VOLUME II. ADAM AND CHARLES BLACK, EDINBURGH; M.DCCC.XLII. t* i v ■ ■ - i' ■ ENCYCLOPAEDIA BRITANNICA A. A THE first letter of the alphabet in every known } language, the Ethiopic or Abyssinian alone excepted, in which it is the thirteenth. Of the sixteen elementary sounds of the human voice, that which is represented by this initial letter is the simplest, and requires the least ex¬ ertion of the organs to produce it; for its enunciation is effected by merely opening the mouth, and breathing, so that the air propelled through the glottis may resound audibly in the cavity of the mouth and nostrils. Hence this sound is remarkable for its universality as well as simplicity. Many of the lower animals possess the capa¬ city of uttering it, as every one must be sensible who has attended to their distinguishing cries, in all, or at least in many of which, it may be easily recognised. It is also the basis, so to speak, of vocality; for, on attentive examina¬ tion, it will be found that the other vowels are little more than labial, lingual, dental, or palatal modifications of this primary, universal, and most elementary sound. It is not without reason therefore that the symbol of this sound is (with one solitary exception) placed at the commencement of every known alphabet. Cicero seems to have disliked the sound of this letter; for in his treatise De Oratore, c. xlix. he denominates it insuavissima littera, probably on account of the out-breathing or expiration necessary to produce the sound of it; but, upon the same principle, the other vowels ought also to have shared his displeasure, seeing that they are merely modifications of this primary aroiyiiov or element. In the English language, A is the mark or symbol of three different sounds, termed by grammarians the broad, the open, and the slender; epithets, the two former of which have an immediate reference to organic modification, as well as to the impulse or volume of voice ; while the latter seems to apply to the degree of intonation alone. Of these varieties of sound, the first, which resembles that of the German A, occurs in such monosyllables as hall, wall, pall, thrall, where the a is pronounced in the same man¬ ner as au in cause ; that is, broad and long. The Saxons, it is probable, expressed only this sound of the letter, which is still commonly retained in the north of England, and prevails universally throughout Scotland, the only parts of the island where the genius and idiom of the Saxon language have withstood modern innovations. The open sound of A, again, resembles that of the Italian in adagio and such like words, and is nearly the same with that of a \n father, rather, &c. But the slender sound, which is peculiar to the English language alone, is identi¬ cal with the sound of the French diphthong ai in such words as mais, paix, gai, and is exemplified in hate, late, waste, paste, place, race; as also in polysyllables, such as toleration, justification, with many others which it is unne¬ cessary to specify. So much for the varieties of this initial sound in English words. A, however, is sometimes employed as an affix in burlesque poetry; in which case it has no other effect than to add a syllable to the line, with¬ out any alteration of the sense, just as the vowel or inter¬ jection O very often does in our old ballads, and in some modern imitations of them. It is also thought to be re¬ dundant and insignificative in such words as arise, awake, aright, adoing, agoing. But this seems a mistake ; for the a here used as a prefix, is probably the French abbreviation of the Latin preposition ad ; and hence it appears to have an intensive effect, adding to and strengthening the import of the word with which it is combined. In the line, “ Arise, awake, or be for ever fall’n,” it is evident that the words “ arise, awake,” convey a meaning stronger in degree than the simple words rise, wake would have done. The pre¬ positionary effect in such words as a-doing, a-going, is in¬ deed admitted by grammarians; but, if this be the case, where is the distinction between these instances and a-rise, a-wake, where the prefix is said to be redundant, except that, by usage, it has coalesced in some measure with the word to which it is prefixed ? In such compounds as afoot, a-sleep, a-week, a-head, a-man, as well as when used before local surnames, as Cornelius a Lapide, Thomas a Kempis, Thomas a Bechet, nobody has ever doubted that the o is a preposition. When a is used as an article, it is merely an abbreviation of the old primary numeral one, one, and consequently it has no plural signification. Thus a house, a field, a ship, mean one house, one field, one ship; but as it is not one of two, ten, or twenty houses, fields, or ships, but of any number, however great or small, hence it be¬ comes in effect quite general and indefinite, or, in other words, the opposite of the, which defines and limits the at¬ tention to something spoken of, pointed out, or referred to. Among the ancients, A was a numeral letter, and stood for 500, and when a dash was placed on the top, thus, A, for ten times that number, or 5000. In the Julian calen- 2 A A. dar it is the first of the seven Dominical Letters. Long before the establishment of Christianity, it had been in use among the Romans as one of the eight Litterce Nundinales ; and it was in imitation of this usage that the Dominical Letters were first introduced. Among logicians, the let¬ ter A is employed as a symbol or sign to denote an uni¬ versal affirmative, in contradistinction to an universal ne¬ gative proposition, in conformity with the following, which is the first verse of a well-known distich: Asserit a, negat e, sed universaliter ambae. Thus, the first mode of the first figure, which is a syllogism consisting of three universal affirmative propositions, is said to be a syllogism in Barbara, a word in which the alphas alone are significant, the repetition of that letter thrice de¬ noting so many of the propositions to be affirmative and universal, conformably to the technical classification— Barbara, Celarent, Darii, Ferio, dato primae. In the public assemblies or comitia of the Romans the let¬ ter A was used in giving votes or suffrages. When a new law was proposed, each voter received a couple of wooden tallies or ballots, one of them marked with a capital A, signifying Antique, q. d. antiquam volo ; and the other with U. R., the initials of Uti Rogas. Those who were against the proposed law, (or rogatio, as it was called) threw the former of these into the urn ; meaning thereby / antiquate it, I prefer the ancient law, and desire no innovations; while such as were favourable to the bill, as we would call it, threw in the latter, signifying, Be it as you desire, or I vote for the measure you propose. A was also marked on tadlies or tablets used in voting in criminal trials, and, stand¬ ing for Absolvo, denoted acquittal; whence Cicero, in his speech for Milo, denominates it littera salutaris, or the letter of acquittal. We may add, in explanation, that, on criminal trials, three of these tallies or tablets were distri¬ buted to each of the judices, or persons constituting the assize, by whom the accused was to be tried; one of them marked with the letter A, absolvo, I acquit; another with the letter C, {littera tristis) condemno, I condemn; and a (| third with the letters N. L. non liquet, it is not clear. From the number of ballots cast into the urn, those marked with N. L. were deducted, and the praetor or magistratus pronounced sentence of acquittal or condemnation, accord¬ ing as the A’s or the C’s were the more numerous. In cases of equality the prisoner was absolved. In ancient inscriptions, whether on marble, brass, or stone, A stands for Augustus, Augustalis, ager, agit, aiunl, aliquando, antique, assolet, aut; A A for Augusti, Au¬ gusta;, Aulus Agerius, ces alienum, ante audita, apud agrum, aurum argentum ; AAA for Augusti when they are three in number, and aurum, argentum, ces; and sometimes its meaning can only be determined by the context of the in¬ scription. Isidore adds, that when this letter occurs after the word miles, a soldier, it denotes him young {miles adolescens). On the reverse of ancient medals, it indi¬ cates the place where they were struck, as Argos or Athens; but on coins of a modern date, it is the mark of the city of Paris, probably taken anagramwise from the last letter of the word Lutetia. A, as an abbreviation, is likewise of frequent occurrence in the works of modern authors; as A. D. for anno Domini, A. M. for artium magister, anno mundi, &c. The letter a with a line above it thus, a, is used in medical prescriptions for ana, of each ; and sometimes it is written thus, dd; for example, met. sacchar, et mann. d vel dd ; that is, take honey, sugar, and manna, of each one ounce. Put to bills of exchange, A is, in England, an abbreviation of accepted, and in France of accepte. It is likewise usual A A L with merchants to mark their sets of books with the letters Aa A, B, C, &c. instead of the ordinary numerals, 1, 2, 3, &c. || A A A is the chemical abbreviation for amalgama or Aalborg. amalgamation.

AALBORG, one of the four sees (stiffs) into which the Danish kingdom, properly so called, to distinguish it from the two provinces of Holstein Sleswick and Lauen- burg, which are a part of Germany, is divided. The see of Aalborg is the northernmost part of the peninsula of Jutland, encompassed on the east, west, and north sides by the ocean, and on the south bounded by the provinces of Ribe, Aarhuus, and Wiborg. The extent is 2902 square miles, or 1,857,280 English acres. The surface is gene¬ rally level, with on the northern part a succession of lakes, that nearly extend from one side of the province to the other. In the north-east and east part are some hills, the highest of which attain the height of 1200 feet. The agriculture is in a neglected state, and the manufactures are in a still lower condition. The chief branch of indus¬ try is the fishing, especially for herrings, which, when cured, are exported in large quantities. The see is di¬ vided into three amts or bailiwicks, comprehending 10 cities, 3 market towns, and 114 parishes. The inhabitants amount to about 124,000: in the year 1814 the births were 2756, and the deaths 1997. The whole of the po¬ pulation are of the Lutheran profession, and speak the Danish language; but among the superior classes the German is generally understood. Aalborg, a city in Denmark, the capital of the see of the same name. It is situated on the Lumfiord, at the spot where the Oosterae joins it; is tolerably fortified; contains a cathedral and several other public buildings, with 830 houses, and 660d inhabitants. There are manufactories of sugar, soap, snuff, chocolate, and scythes, with several distilleries; but the woollen and hosiery trades which formerly existed are nearly ex¬ tinct. The entrance to the harbour is such as to require vessels drawing more than 10 feet of water to lighten be¬ fore they approach the city. The chief exports are her¬ rings, corn, wool, hides, tar, tallow, and corn spirits. It is in Lat. 57. 2. 57. N., and Long. 9. 50. 36. E. The amt or bailiwick of Aalborg, which is the best part of the see, extends over 1088 square miles, of which three-fifths is ploughed land, and the rest either heaths or morasses, with some woods. It has 3 cities, 2 towns, 113 villages, and 64,600 inhabitants. .AAR Aalen AALEN, a bailiwick in the circle of Jaxt, in the king- 11 dom of Wirtemherg. Its extent is 108 square miles, or Aargau. 69,120 acres. It is watered by the river Kocher, has --^v^^some lofty mountains in the southern part, and is most abundantly wooded. It produces but little corn, and nei¬ ther fruit nor wine, but pastures a competent number of cattle. There are some iron mines worked. Many arti¬ cles of wood-ware are produced, and some wool and cotton are spun. It contains one city, one market town, and 190 smaller towns and villages, with 17,899 inhabitants. Aalen, a city, the capital of the bailiwick of the same name. Its chief trade is in woollens and in breweries, and some cotton is spun. It contains 2370 inhabitants. It is in Lat. 48. 47. 20. N. Long. 10. 7. 27. E. AALSMEER, a town in the arrondissement of Am¬ sterdam, in the province of North Holland. It is near the lake of Haarlem ; celebrated for its strawberries; con¬ tains 1811 inhabitants, employed in making cotton goods. AALTEN, a town in the arrondissement of Zutphen, and province of Gelderland, in the Netherlands, contain¬ ing 3524 inhabitants. AAM, or Haam, a liquid measure in common use among the Dutch, containing 128 measures called mingles, each weighing nearly 36 ounces avoirdupois; whence the Aam contains 288 English, and 148f pints Paris measure. AAMADOT, a town of Norway, in the bailiwick of Hedemarken and see of Aggerhuus. It is situated on the river Glommen, has 2729 inhabitants, and some trade in making woollen and cotton caps. AAR, the name of two rivers; one in Switzerland, the other in Westphalia, in Germany. It is also the name of a small island in the Baltic. AARASSUS, in Ancient Geography, a town of Pisidia, in the Hither Asia, thought to be the Anassus of Pto¬ lemy. AARAU, or Arau, a circle in the canton of Aargau, in Switzerland, containing the city from which its name is derived, and 12 other places, with 2260 houses and 11,820 inhabitants. Aarau, the chief city of the canton of the same name, on the banks of the river Aar, over which there is a covered bridge. It is well built, paved, and, at night, lighted. It has a handsome government house, a church, a hospital, 427 dwellings, and 3100 inhabitants, who are very industrious manufacturers. The chief pursuits are making silk ribbons, spinning and weaving cotton, some tanning and cutlery, bleaching, and casting cannon. It is in Lat. 47. 23. 31. N. Long. 8. 4. 32. E. AARBURG, a city in Switzerland, in the circle of Zofin- gen, and canton of Aargau. It stands at the confluence of the rivers Aar and Bigger, has a strongly fortified castle, the only one in Switzerland, which is the depot for mili¬ tary stores. The city contains 154 houses, and 1000 in¬ habitants, who make cotton goods and hosiery. AARDENBURG, a town in the arrondissement of Middleburg, in the province of Zealand, in the kingdom of the Netherlands, with 1376 inhabitant*. AARGAU, or Argovia, one of the cantons of Swit¬ zerland. It was originally a part of Berne, but by ar¬ rangements begun in 1798, and continued in 1803, it was erected into a separate and independent canton. It is bounded on the north by the river Rhine, which divides it from the duchy of Baden, on the east by Zurich, on the south-east by Zug, on the south by Lucerne, on the south-west by Berne, and on the west by Solothurn and Basle. Its extent is about 600 square miles, and its divi¬ sions are into eleven circles, which are again subdivided into forty-eight smaller ones. By the census taken in 1814, the number of inhabitants appeared to be 143,960, and AAR 3 they are supposed to have increased since that period. Aargau Then the reformed Protestants were 75,279, and the Ca- || tholics 67,000, besides which there were about 1800 Jews. Aaron. The greater part of the canton is either level or undu-^^^^-^ lating, but some of the mountains on the right bank of the Aar are of the height of 2700 feet. The chief river is the Rhine, which forms the boundary, and is navigable, though, on account of shoals and rocks, with difficulty. That river receives into it the water of the Aar, the Wig- ger, the Suren, the Reuss, and the Limmath, as well as that of many smaller brooks and rivulets. The climate is milder than in most parts of Switzerland. In the valley of the Aar figs and almonds ripen, and some wine is pro¬ duced. The principal occupation is husbandry. The products are corn, wine, and some rape-oil, hemp, flax, potatoes, wood, and turf, and all the common kinds of cattle. Some iron is drawn from the mines by Tegerfel- den. The trade consists in the export of corn and wine, and of some cotton and half-cotton goods, silk ribbons, cutlery, leather, straw hats, and some smaller wares. The legislative power is in the greater council of 150, and the smaller, of 13 members, exercise the executive. These consist of half Catholics and half Protestants. In each circle is an amtman or bailiff, and in each subdivi¬ sion a justice of the peace, from whom there is an appeal to a supreme court, composed equally of Protestants and Catholics. The contingent of men for the defence of the confederation is 2410, and of money 48,200 francs. The income of the canton is supposed to amount to 500,000 francs, arising from land, salt, and gun-powder monopoly, tolls, and postage. The expenditure is 10,000 francs less than the income. AARHUUS, one of the sees {stiffs) into which Den¬ mark is divided. It is in the southernmost part of the peninsula of Jutland. The extent is 1810 square miles, or 1,158,400 acres. It is a level country, somewhat un¬ dulating, having on its coasts several indentions forming bays, and in the exterior having several lakes, rivers, low hills, and woods. The climate is considered to be the best in Jutland. The greater part of the inhabitants are engaged in cultivation, and produce more corn, potatoes, and flax, than their consumption requires, and thus leave a portion for exportation. The ecclesiastical bishopric of Aarhuus differs from the political see. The latter is di¬ vided into two jurisdictions or bailiwicks, and 22 baronies {herrerders) comprehending 7 cities, 253 parishes, and 69 noble domains and dwellings. The inhabitants amount to 88,000, many of whom are occupied in the fisheries, and the females in spinning. Aarhuus, one of the bailiwicks into which the see of the same name in Denmark is divided. Its extent is 864 square miles, or 558,400 acres, comprehending 2 cities and 134 parishes, divided into 12 baronies, and containing 42,100 inhabitants. Aarhuus, a city, the capital of the see and of the bailiwick of the same name. It is situated on the Cattegat, in a low plain, where an inland lake empties itself into the sea. The cathedral is a Gothic building, and the largest church in Denmark. It contains 892 dwelling-houses, and about 6000 inhabitants. The harbour is small, but good and secure; and there are 46 vessels belonging to the city, chiefly in the coasting trade, but lately have gone on voyages to the West Indies. There are some sugar-houses, tanneries, and snuff-mills. The chief ex¬ ports are corn, wool, and fish. It is in Lat. 56. 9. 35. N. Long. 10. 8. E. AARON, high-priest of the Jews, and brother to Moses, was by the father’s side great-grandson, and by . the mother’s, grandson of Levi. By God’s command he AAR Aaron met Moses at the foot of Mount Horeb, and they went i. together into Egypt to deliver the children of Israel. He had a great share in a11 tllat Moses did f01, their deliver¬ ance. The Scriptures call him the prophet of Moses, and he acted in that capacity after the Israelites had passed oyer the Red Sea. He ascended Mount Sinai with two of his sons, Nadab and Abihu, and seventy elders of the people; but neither he nor they went higher than half¬ way, from whence they saw the glory of God; only Moses and Joshua went to the top, where they stayed forty days. During their absence, Aaron, overcome by the people's eager entreaties, set up the golden calf, which the Israel¬ ites worshipped by his consent. This calf has given rise to various conjectures. Some Rabbis maintain that he did not make the golden calf, but only threw the gold into the fire, to get rid of the importunities of the people; and that certain magicians who mingled with the Israelites at their departure from Egypt, cast this gold into the figure of a calf. According to some authors, the fear of falling a sacrifice to the resentment of the people, by giving a refusal, made Aaron comply with their desire: and they allege also, that he hoped to elude their request, by demanding of the women to contribute their ear-rings; imagining they would rather choose to remain without a visible deity, than be deprived of their personal orna¬ ments. This affair of the golden calf happened in the third month after the Israelites came out of Egypt. In the first month of the following year, Aaron was appoint¬ ed by God high-priest; which office he executed during the time that the children of Israel continued in the wil¬ derness. He died upon Mount Hor, in the fortieth year after the departure from Egypt, being then 123 years old; a. m. 2522, of the Julian period 3262, before the Chris¬ tian era 1452. Aaron, the Caraite, a learned Jew who flourished about the year 1299. He left many works on the Old Testa¬ ment, among which there is one entitled H Commentary on the Pentateuch, which has been much valued. It was written in Hebrew, and printed in folio with a Latin translation, at Jena, in 1710. Aaron, another Caraite Jew, who lived in the 15th century, wrote a concise Hebrew grammar, entitled The Perfection of Beauty, which was printed at Constantinople in 1581. F Aaron and Julius, Saints, were brothers who suffer¬ ed martyrdom together, during the persecution under the emperor Dioclesian, in the year 303, about the same time with St Alban the first martyr of Britain. We are not told what their British names were, it being usual with the Christian Britons, at the time of baptism, to take new names from the Greek, Latin, or Hebrew. Nor have we any certainty as to the particulars of their death; only that they suffered the most cruel torments. Two churches were dedicated to the brothers, in which their bodies were interred, at Caer-Leon, the ancient metropolis of Wales. Aaron, or Haroun, Al Raschid, a celebrated caliph, or Mahometan sovereign of the Saracen empire; whose his¬ tory is given under the article Bagdad. AARSENS, Francis, Lord of Someldyck and Spyck, one of the greatest negotiators of the United Provinces. He was born at the Hague in 1572. His father, Cor¬ nelius Aarsens, was secretary to the States; and being acquainted with Mr Mornay du Plessis, at the court of William prince of Orange, he prevailed upon him to take his son under him, with whom he continued some years. John Olden Barneveldt, who presided over the affairs of Holland and all the United Provinces, sent him afterwards as resident into France, where he learned to negotiate under those profound politicians A B Ab.

Laert. in Vita Solonis.) fi ABA Abacus, ing of balanced accounts, says, that the pebbles were clear- ed away, and none left.1 His rival, Demosthenes, repeat¬ ing his expression, employs further the verb avran\uv, which means to take up as many counters as were laid down. It is evident, therefore, that the ancients, in keep¬ ing their accounts, did not separately draw together the credits and the debts, but set down pebbles for the for¬ mer, and took up pebbles for the latter. As soon as the board became cleared, the opposite claims were exactly balanced. We may observe, that the phrase to clear ones scores or accounts, meaning to settle or adjust them, is still preserved in the popular language of Europe, being suggested by the same practice of reckoning with count¬ ers, which prevailed indeed until a comparatively late period. Roman The Romans borrowed their Abacus from the Greeks, Abacus. and never aspired higher in the pursuit of science. To each pebble or counter required for that board they gave the name of calculus, a diminutive formed from calx, a stone; and applied the verb calculate, to signify the ope¬ ration of combining or separating such pebbles or count¬ ers. Hence innumerable allusions by the Latin authors. Ponere calculum—subducere calcidum, to put down a counter, or to take it up; that is, to add or subtract; co- care aliquid ad calculum, ut par sit ratio acceptorum et da- torum—to submit any thing to calcidation, so that the ba¬ lance of debtor and creditor may be struck. The emperor Helvius Pertinax, who had been taught, while a boy, the arts of writing and casting accounts, is said, by Julius Ca- pitolinus, to be litteris elementariis et calcido imbutus. St Augustine, whose juvenile years were devoted to pleasure and dissipation, acquaints us, in his extraordinary Con¬ fessions, that to him no song ever sounded more odious than the repetition or cantio, that one and one make two, and two and two make four. The use of the Abacus, call¬ ed sometimes likewise the Mensa Pythagorica, formed an essential part of the education of every noble Roman youth: Nec qui abaco numeros, et secto in pulvere met a a Scit risisse vafer. Peks. Sat. i. 131. From Martianus Capella we learn that, as refinement advanced, a coloured sand, generally of a greenish hue, was employed to strew the surface of the abacus. Sic abacum perstare jubet, sic tegmine glauco Pandere pulvereum formarum ductibus sequor. Lib. vii. De Arithmetica. A small box or coffer, called a Loculus, having com¬ partments for holding the calculi or counters, was a ne¬ cessary appendage of the abacus. Instead of carrying a slate and satchel, as in modern times, the Roman boy was accustomed to trudge to school, loaded with his arithme¬ tical board, and his box of counters: Quo pueri magnis e centurionibus orti, Lcevo suspensi loculos tubulamque lacerto. Horat. Sat. i. 6. In the progress of luxury, tali, or dies made of ivory, Avere used instead of pebbles, and small silver coins came to supply the place of counters. Under the em¬ perors, every patrician living in a spacious mansion, and indulging in all the pomp and splendour of eastern princes, generally entertained, for various functions, a nu¬ merous train of foreign slaves or freedmen in his palace. Of these, the librarius or miniculator, was employed in c u s. teaching the children their letters; but the notarius re- Abacus, gistered expenses, the rationarius adjusted and settled accounts, and the tabularius or calculator, working with his counters and board, performed what computations might be required. Sometimes these laborious combiners of numbers were termed reproachfully canculones or cal- cidones. In the fervour of operation, their gestures must often have appeared constrained and risible. Computat, ac cevet. Ponatur calculus, adsint Cum tabula pueri. Juv. Sat. ix. 40. The nicety acquired in calculation by the Roman youth, was not quite agreeable to the careless and easy temper of Horace. Romani puen longis rationibus assem Discunt in parteis centum diducere. Dicat Filius Albini, Si de quincunce remota est Uncia, quid superet ? Poteras dixisse, Triens. Eu ! Rem poteris servare tuam. Redit uncia; quid fit ? Semis. Episl. ad Pisones. It was a practice among the ancients to keep a diary, by marking their fortunate days by a lapillus, or small white pebble, and their days of misfortune by a black one. Hence the frequent allusions which occur in the Classics: O diem laetum, notandumque mihi candidissimo calculo ! Plin. Epist. vi. 11. diesque nobis Signandi melioribus lapiltis ! Mart. ix. 53. Hunc, Macrine, diem numera meliore lapillo, Qui tibi labentes apponit candidus annos. Pers. Sat. ii. 1, 2. To facilitate the working by counters, the construction of the abacus was afterwards improved. Instead of the perpendicular lines or bars, the board had its surface di¬ vided by sets of parallel grooves, by stretched wires, or even by successive rows of holes. It was easy to move small counters in the grooves, to slide perforated beads along the wires, or to stick large nobs or round-headed nails in the different holes. To diminish the number of marks required, every column was surmounted by a short¬ er one, wherein each counter had the same value as five of the ordinary kind, being half the index of the Denary Scale. The abacus, instead of wood, was often, for the sake of convenience and durability, made of metal, fre¬ quently brass, and sometimes silver. In the Plate en¬ titled Arithmetic, we have copied, from the third vo¬ lume of the Supplement added by Polenus to the im¬ mense Thesaurus of Graevius, two varieties of this instru¬ ment, as used by the Romans. They both rest on good authorities, having been delineated from antique monu¬ ments,—the first kind by Ursinus, and the second by Marcus Velserus. In the one, the numbers are repre¬ sented by flattish perforated beads, ranged on parallel wires; and, in the other, they are signified by small round counters moving in parallel grooves. These instruments contain each seven capital bars, expressing in order units, tens, hundreds, thousands, ten thousands, hundred thousands, and millions; and above them are shorter bars following the same progression, but having five times the relative value. \\ ith four beads on each of the long wires, and 1 Kcf,v xaJaoai uffiv ai YrioMu- insular Hyperboreans, makes him a Scythian ; as do some jfrar/(S others, misled by the same vulgar error ; though Diodorus vop j, ’ has truly fixed his country in an island, and not on the con-p. 161. tinent. Indeed (continues Mr Toland) the fictions and8 Diod. Sic. mistakes concerning our Abaris are infinite : however, it^b. ii. iii. is agreed by all that he travelled quite over Greece, and from thence into Italy, where he conversed familiarly with Pythagoras, who favoured him beyond all his dis¬ ciples, by instructing him in his doctrines (especially his thoughts of nature) in a plainer and more compendious method than he did any other. This distinction could not but be very advantageous to Abaris. The Hyper¬ borean, in return, presented the Samian, as though he equalled Apollo himself in wisdom, with the sacred arrow on which the Greeks have fabulously related9 that he 2 J.-.mb- sat astride, and flew upon it, through the air, over rivers hchi Vita and lakes, forests and mountains; in like manner as our vulgar still believe, particularly those of the Hebrides, P" that wizards and witches fly whithersoever they please on their broom-sticks. The orator Himerius above mention¬ ed, though one of those who, from the equivocal sense • of the word Hyperborean, seem to have mistaken Abaris for a Scythian, yet describes his person accurately, and gives him a very noble character. “ They relate,” says he, “ that Abaris the sage was by nation a Hyperbo¬ rean, appeared a Grecian in speech, and resembled a Scythian in his habit and appearance. He came to Athens holding a bow in his hand, having a quiver hanging on his shoulders, his body wrapt up in a plaid, girt about the loins with a gilded belt, and wearing trousers reaching from his v/aist downward.” By this it is evident (says Mr Toland) that he was not habited like the Scythians, who were always covered with skins ; but appeared in the na¬ tive garb of an aboriginal Scot. ABARTICULATION, in Anatomy, a species of arti¬ culation, admitting of a manifest motion ; called also Di¬ arthrosis, and Dearticulatio, to distinguish it from that sort of articulation which admits of a very obscure motion, and is called Synarthrosis. ABAS, a weight used in Persia for weighing pearls. It is one-eighth less than the European carat. Abas, in heathen mythology, was the son of Hypothoon and Meganira, who entertained Ceres, and offered a sacrifice to that goddess; but Abas ridiculing the ceremony, and giv¬ ing her opprobrious language, she sprinkled him with a certain mixture she held in her cup, on which he became a newt or water lizard. ABASCIA, or Abcassia, the northern district of the western division of Georgia, situated on the coast of the Black Sea, and tributary to the Turks. The inhabitants trade in furs, tiger-skins, linen yarn, boxwood, and bees’ ABA ABA 11 Abansi wax; but their principal traffic consists in the sale of || their own children to the Turks, and to one another. Abatos. They have the name of Christians, but have nothing left '^v^x*>,but the name, any more than the Mingrelians their north¬ ern neighbours. ABASSI, or Abassis, a silver coin current in Persia, equivalent in value to a French livre, or tenpence half¬ penny sterling. It took its name from Schah Abbas II. king of Persia, under whom it was struck. ABASSUS, in Ancient Geography, a town of the Greater Phrygia, on the confines of the Tolistobagii, a people of Galatia in Asia. ABASTAS, a town in the department of Carrion, and pr : vince of Toro, in Spain. ABATAMENTUM, in Law, is an entry to lands by interposition, i. e. when a person dies seized, and another who has no right enters before the heir. ABATE, in the manege, implies the performing any downward motion properly. Thus a horse is said to abate or take down his curvets, when he puts both his hind legs to the ground at once, and observes the same exactness in all the times. To Abate, (from the French abattre, to pull down, overthrow, demolish, batter down, or destroy,) a term used by the writers of the English common law both in an active and neuter sense ; as, To abate a castle, is to beat it down. To abate a writ, is, by some exception, to defeat or overthrow it. A stranger abateth; that is, entereth upon a house or land void by the death of him that last possessed it, before the heir takes possession, and so keepeth him out: wherefore, as he that putteth out him in possession is said to disseize, so he that steppeth in between the former possessor and his heir is said to abate. In the neuter signification thus : The writ of the demandant shall abate; that is, shall be disabled, frus¬ trated, or overthrown. The appeal abateth by covin ; that is, the accusation is defeated by deceit. ABATELMENT, in commerce, a term used for a pro¬ hibition of trade to all French merchants in the ports of the Levant who will not stand to their bargains, or refuse to pay their debts. It is a sentence of the French consul, which must be taken off before they can sue any person for the payment of their debts. ABATEMENT, in Heraldry, an accidental figure sup¬ posed to have been added to coats of arms, in order to denote some dishonourable demeanour or stain, whereby the dignity of coat armour was rendered of less esteem. ABATIS, an ancient term for an officer of the stables. Abatis, or Abattis, in military affairs, a kind of de¬ fence made of felled trees. In sudden emergencies, the trees are merely laid lengthwise beside each other, with the branches pointed outwards to prevent the approach of the enemy, while the trunks serve as a breast-work to the de¬ fendants. When the abatis is employed for the defence of a pass or entrance, the boughs of the trees are stripped of their leaves and pointed, the trunks are planted in the ground, and the branches interwoven with each other. ABATON, a building at Rhodes, erected as a fence to the trophy of Artemisia, queen of Halicarnassus, Coos, &c. raised in memory of her victory over the Rhodians ; or rather to conceal the disgrace of the Rhodians from the eyes of the world; for, to efface or destroy the trophy was with them a point of religion. ABATOR, in Law, a term applied to a person who enters a house or lands void by the death of the last pos¬ sessor, before the true heir. ABATOS, in Ancient Geography, an island in the lake near Memphis, formerly famous for its papyrus. It was the burial place of Osiris. ABATSKAJA, a town on the river Tabask, in the Abatskaja circle of Ischim and stadtholdership of Tobolsk, in the || Russian dominion of Siberia, in Asia. It may be more Abauzit. properly denominated a township, as the dwellings are'w‘^v^w/ scattered about at considerable distance from each other. The houses are 385, and the inhabitants about 2000. ABAUJVAR, one of the palatinates into which the Austrian kingdom of Hungary is divided. Its extent is about 700,000 acres, nearly one-half of which is in woods, the other half cultivated. It contains one city, 10 mar¬ ket towns, and 227 villages. The inhabitants are about 140,000, mostly Catholics; the remainder Lutherans, Calvinists, and Greek church, with some Jews. The chief productions are corn, flax, hemp, tobacco, fruit, wine, and wood. There are also valuable quarries of marble. ABAUZIT, Firmin, a learned Frenchman, was born at Usez, in Languedoc, in November 1679. His father died when he was but two years of age. To avoid the rigours of persecution to which the Protestants of France were exposed in the time of Louis XIV. young Abauzit’s mother, who was a Protestant, fled with her son to Geneva, wdiere he remained secure from danger, and enjoyed the benefit of education. From his 10th to his 19th year, his time was wholly devoted to literature; and having made great progress in languages, he studied mathematics, physics, and theology. In the year 1698, he travelled into Holland, where he became acquainted with Bayle, Basnage, and Jurieu. Thence he passed over to England, and was introduced to Sir Isaac Newton, who entertained a very high opinion of his merit. For this philosopher afterwards sent him his Commercium Epistolicum, accom¬ panied with a very honourable testimony: “ You are well worthy, says Newton, to judge between Leibnitz and me.” The reputation of Abauzit reached the ears of King William, who encouraged him by a very handsome offer to settle in England; which he declined, and returned to Geneva. In 1715 he entered into the society formed for the purpose of translating the New Testament into the French language, and contributed valuable assistance to this work. The chair of philosophy in the university was offered to him in 1723, which he refused; but in 1727 he accepted of the office of librarian to the city, the duties of which were neither burdensome, nor subjected him to any particular restraint. Abauzit was one of the first who embraced the grand truths which the sublime discoveries of Newton disclosed to the world. He defended the doctrines of that philo¬ sopher against Father Castel; and discovered an error in the Principia, which was corrected by Newton in the second edition of his work. He was a perfect master of many languages; his knowledge was extensive and pro¬ found ; and the different sciences which he had studied were so well digested and arranged in his retentive mind, that he could at once bring together all that he ever knew on any subject. Rousseau (in his Heloise) addressed to Abauzit one of the finest panegyrics which he ever wrote; and a stranger having addressed Voltaire in a flatter¬ ing manner, by saying he had come to Geneva to see a gre^t man, the poet asked him whether he had seen Abauzit. This excellent man, having lived universally respected to the great age of 87 years, died in the year 1767, la¬ mented by the republic, and regretted by the learned. His writings are chiefly on religious subjects; but he was also the author of several antiquarian and critical pieces. In his Essay on the Apocalypse, he endeavoured to show, that the predictions in that book were to be ap¬ plied to the destruction of Jerusalem. This work was translated into English by Dr Twells, who added a re¬ futation, which satisfied Abauzit so much that he was 12 ABB Abavo mistaken in his views, that he ordered an edition then II ready for publication in Holland to be stopped. His Abbas, other theological works are, Reflections on the Eucharist; On Idolatry; On the Mysteries of Religion; and Para¬ phrases and Explanations of sundry parts of Scripture. His principal works were published in Holland in 1773, by Be- renger, in 2 volumes 8vo. under the title CEuvres de feu M. Abauzit. ABAVO, in Botany, a synonyme of the Adansonia. ABB, a term among clothiers applied to the yarn of a weaver’s warp. They say also Abb-wool in the same sense. ABBA, in Ancient Geography, a town of Africa Pro¬ pria, near Carthage. Abba, in the Syriac and Chaldee languages, literally signifies a father ; and figuratively, a superior, reputed as a father in respect of age, dignity, or affection. It is more particularly used in the Syriac, Coptic, and Ethiopic churches, as a title given to the bishops. The bishops themselves bestow the title of Abba more eminently on the bishop of Alexandria; which occasioned the people to give him the title of Babba, or Papa, that is Grandfather; a title which he bore before the bishop of Rome. It is a Jewish title of honour given to certain Rabbis called Tanaites: and it was particularly used, by some writers of the middle age, for the superior of a monastery, usually called abbot. ABB AC H, a town of the kingdom of Bavaria, on a stream flowing into the Danube, with a castle, in which the Emperor Henry II. was born. It is in the district of Kellhaim, and circle of Regensburg, with 600 inhabitants. ABBADIE, James, an eminent Protestant divine, born at Nay in Bern in 1654i; first educated there under the fa¬ mous John la Placette, and afterwards at the university of Sedan, from whence he went into Holland and Ger¬ many, and was minister in the French church of Berlin. He left that place in 1690; came into England ; was some time minister in the French church in the Savoy, Lon¬ don ; and was made dean of Killalo in Ireland. He was strongly attached to the cause of King William, as ap¬ pears in his elaborate defence of the Revolution, and his History of the Assassination Plot. The materials for the last were furnished by the secretaries of state. He had great natural abilities, which he improved by useful learn¬ ing. He was a most zealous defender of the primitive doc¬ trine of the Protestants, as appears by his writings; and that strong nervous eloquence for which he was so remark¬ able, enabled him to enforce the doctrines of his profes¬ sion from the pulpit with great spirit and energy. He possessed uncommon powers of memory. It is said that he composed his works without committing any part to writing, till they were wanted for the press. He died in London in 1727, after his return from a tour in Hol¬ land. He published several works in French that were much esteemed; the principal of which are, A Treatise on the Truth of the Christian Religion ; The Art of Know¬ ing one’s Self; A Defence of the British Nation, that is, of the Revolution 1688 ; the Deity of Jesus Christ essen¬ tial to the Christian Religion; The History of the last Conspiracy in England, called the Assassination Plot, writ¬ ten by order of King William III.; and the Triumph of Providence and Religion, or the opening the Seven Seals by the Son of God. ABBAS, Mahomet’s Uncle, opposed his nephew with all his power, regarding him as an impostor and traitor to his country; but in the second year of the Hegira, being overcome and made a prisoner at the battle of Beder in 623, a great ransom being demanded for him, he repre¬ sented to Mahomet, that his paying it would reduce him to beggary, which would bring dishonour on the family. ABB Mahomet, who knew that he had concealed large sums of Abbas money, said to him, “ Where are the purses of gold that II you gave your mother to keep when you left Mecca ? Mb03** Abbas, who thought this transaction secret, was much surprised; and conceiving that his nephew was really a prophet, embraced his religion. He became one of his principal captains, and saved his life when in imminent danger at the battle of Honain, against the Thakesites, soon after the reduction of Mecca. But besides being a great commander, Abbas was one of the first doctors of Islamism. He is said to have read lectures on every chapter of the Koran, as his nephew pretended to receive them from heaven. He died in 652, and his memory is held in the highest veneration among the Mussulmans to this day. Abbas, Schah, the Great, was third son of Codabendi, 7th king of Persia of the race of the Sophis. Succeeding to his father in 1585, at the age of 18, he found the affairs of Persia at a low ebb, occasioned by the conquests of the Turks and Tartars. He regained several of the provinces they had seized; but death put a stop to his victories in 1629, after a reign of 44 years. He was the greatest prince who had reigned in Persia for many ages ; and it was he who made Ispahan the metropolis of Persia. His memory is held in the highest veneration among the Persians. Abbas, Schah, his grandson, 9th king of Persia of the race of the Sophis, succeeded his father Sesi at 13 years of age. He was but 18 when he made himself master of the city of Candahar, which had surrendered in his father’s reign to the great Mogul, and all the province about it; and he preserved it afterwards against this Indian emperor, though he besieged it more than once with an army of 300,000 men. He was a very merciful prince, and openly protected the Christians. He had formed a design of ex¬ tending the limits of his kingdom toward the north, and had for that effect levied a powerful army; but death put a stop to all his great designs, at 37 years of age, a. d. 1666. ABBASSIDES, the name of a race who possessed the caliphat for 524 years. There were 37 caliphs of this race who succeeded one another without interruption. ABBATEGGIO, a town in the kingdom of Naples, in the province of Abruzzo Citeriore, with 440 inhabitants. ABBE', in a monastic sense, the same with Abbot. Abbe', in a modern sense, the denomination of a class of persons which has been popular in France. They were not in orders; but having received the ceremony of tonsure, were entitled to enjoy certain privileges in the church. The dress of abbes was that of academics or professed scholars. In colleges they were the instructors of youth, and were employed as tutors in private fami¬ lies. Many of them have risen to a distinguished rank in the state, while others have been no less eminent in science and literature. ABBEHAUSEN, a bailiwick or circle of Oldenburg, in the duchy of Holstein Oldenburg, in Germany. It con¬ tains 1255 houses and 6263 inhabitants. The chief town of the same name has 303 houses and 1502 inhabitants. ABBESS, the superior of an abbey or convent of nuns. The abbess has the same rights and authority over her nuns that the abbots regular have over their monks. I he sex indeed does not allow her to perform the spiritual functions annexed to the priesthood, with which the abbot is usually invested; but there are instances of some abbesses who have a right, or rather a privilege, to commission a priest to act for them. They have even a kind of epis¬ copal jurisdiction, as well as some abbots who are exempt¬ ed from the visitation of their diocesans. Martene, in his treatise on the rights of the church, observes, that abbesses formerly confessed nuns; but ABB Abbeville he adds, that their excessive curiosity carried them such II lengths, that there arose a necessity of checking it. How- Abbey. ever> st Basil, in his Rule, allows the abbess to be pre- ' sent with the priest at the confession of her nuns. ABBEVILLE, an arrondissement of the department of the Somme, in the north-east of France, which extends over 606 square miles, or 387,840 acres. It is divided into 11 districts and 178 communes, and contains 120,303 inhabitants. Abbeville, a city, the capital of the arrondissement of that name, through which the river Somme passes. It is strongly fortified, and the country around it can be easily inundated. It is built in the old mode, has several bridges, 4 squares, 14 churches, one of them, St Wulfram’s, very an¬ tique and curious; 3641 houses, and 17,900 inhabitants. It has long been the seat of the woollen manufacture, be¬ sides which there are manufactories for linen, cotton, soap, leather, and twine. The river is navigable by the help of the tides; and by it oil, linseed, and hemp, are export¬ ed. It is in Lat. 50. 7. 4. N. Long. 1. 43. 50. E. ABBEY, a monastery, or religious house, governed by a superior under the title of abbot or abbess. Abbeys differ from priories in this, that the former are under the direction of an abbot, the latter of a prior; for abbot and prior (we mean a prior conventual) are much the same thing, differing in little but the name. Fauchet observes, that, in the early days of the French monarchy, dukes and counts were called abbots, and duchies and counties abbeys. Even some of their kings are men¬ tioned in history under the title of abbots. Philip I. Louis VI. and afterwards the duke of Orleans, are called abbots of the monastery of St Aignan. The dukes of Aquitain were called abbots of the nwnastery of St Hillary at Poic- tiers ; and the earls of Anjou, of St Aubin, Sfc. Monasteries were at first established as religious houses, to which persons retired from the bustle of the world to spend their time in solitude and devotion. But they soon degenerated from their original institution, and obtained large privileges, exemptions, and riches. They prevailed greatly in Britain before the Reformation, particularly in England; and as they increased in riches, so the state became poor: for the lands which these regulars possessed were in mortua manu, i. e. could never revert to the lords who gave them. This inconvenience gave rise to the statutes against gifts in mortmain ; and Lord Coke tells us, that several lords, at their creation, had a clause in their grant, that the donor might give or sell his land to whom he would (exceptis viris religiosis et Judceis) ex¬ cepting monks and Jews. These places were wholly abolished in England at the time of the Reformation; Henry VIII. having first ap¬ pointed visitors to inquire into the lives of the monks and nuns, which were found in some places to be extremely irregular. The abbots, perceiving their dissolution unavoid¬ able, were induced to resign their houses to the king, who by that means became invested with the abbey lands: these were afterwards granted to different persons, whose descendants enjoy them at this day. Though the suppression of religious houses, even con¬ sidered in a political light only, was a national benefit, it must be owned, that at the time they flourished, they were far from useless. Abbeys or monasteries were then the repositories, as well as the seminaries, of learning; many valuable books and national records, as well as private history, having been preserved in their libraries, the only places in which they could have been safely lodged in those turbulent times. Many of those which had escaped the ravages of the Danes, were de¬ stroyed with more than Gothic barbarity at the dissolu- A B B 33 tion of the abbeys. These ravages are pathetically lament- Abbey ed by John Bale : “ A number of those,” says he, “ who II purchased these superstitious mansions, reserved of the library books, some to serve their jakes, some to scour the candlesticks, and some to rub their boots; some they sold to the grocer and soapseller; and some they sent over sea to the bookbinders, not in small numbers, but in whole ships full; yea, the universities of this realm are not clear of so detestable a fact. I know a merchant that bought the contents of two noble libraries for 40s. price; a shame it is to be spoken ! This stuff hath he occupied instead of gray paper, by the space of more than these ten years, and yet he hath store enough for as many years to come. I shall judge this to be true, and utter it with heaviness, that neither the Britons under the Romans and Saxons, nor yet the English people under the Danes and Normans, had ever such damage of their learned mo¬ numents as we have seen in our time.” Every abbey had at least one person whose office it was to instruct youth; and the historians of this country are chiefly beholden to the monks for the knowledge they have of former national events. In these houses also the arts of painting, architecture, and printing, were cultivated. They were hospitals for the sick and poor, and afforded entertainment to travellers at a time when there were no inns. They were likewise an asylum for aged and indigent persons of good family. ABBEYBOYLE, a town of Ireland, in the county of Roscommon, and province of Connaught. It is remarkable for an old abbey. ABBEYHOLM, a town in Cumberland, so called from an abbey built there by David king of Scots. It stands on an arm of the sea. ABBIATE GRAFFO, a town in the Austrian delega¬ tion of Pavia, in Italy. It is situated on the great Navig- lio, where that river divides into three branches. It con¬ tains 4000 inhabitants, who cultivate around the place large portions of rice. ABBOT, or Abbat, the superior of a monastery of monks erected into an abbey or priory The name Abbot is originally Hebrew, where it signi¬ fies father. The Jews call father, in their language, Ab ; whence the Chaldeans and Syrians formed Abba ; thence the Greeks ASCag, which the Latins retained; and hence our Abbot, the French Abbe, &c. St Mark and St Paul use the Syriac Abba in their Greek, by reason it was then commonly known in the synagogues and the primitive as¬ semblies of the Christians; adding to it, by way of inter¬ pretation, the word father, A££a 6 . if<{. totidem praelectionibus in Schola Theologica Oxonias, pro forma habitis, discuss® et disceptat® anno 1597, in qui- bus e Sacra Scriptura et Patribus, quid statuendum sit definitur.

Abbot, Robert, elder brother to the former, was born at Guildford in 1560, and completed his studies at Baliol college, Oxford. In 1582, he took his degree of master of arts, and soon became a celebrated preacher; and to this talent he chiefly owed his preferment. Upon the first sermon at Worcester, he was chosen lecturer in that city, and soon after rector of All-saints in the same place. In 1597, he took his degree of doctor in divinity: and, in the beginning of King James’s reign, was appointed chap¬ lain in ordinary to his majesty; who had such an opinion of him as a writer, that he ordered the doctor’s book De Antichristo to be printed, with his own commentary upon part of the Apocalypse. In 1609, he was elected master of Baliol college; which trust he discharged with the ut¬ most care and assiduity, by his frequent lectures to the scholars, by his continual presence at public exercises, and by promoting temperance in the society. In No¬ vember 1610, he was made prebendary of Norman ton in the church of Southwell; and, in 1612, his majesty ap¬ pointed him regius professor of divinity at Oxford. The fame of his lectures became very great; and those which he gave upon the supreme power of kings, against Bellar- mine and Suarez, so much pleased his majesty, that when the see of Salisbury became vacant, he named him to that bishopric, and he was consecrated by his own bro¬ ther at Lambeth, December B. 1615. When he came to Salisbury, he found the cathedral falling to decay, through the avarice and negligence of the clergy belonging to it; however, he found means to draw five hundred pounds from the prebendaries, which he applied towards repair¬ ing it. Here he devoted himself to the duties of his function with great diligence and assiduity, visiting his whole diocese in person, and preaching every Sunday. But his sedentary life, and close application to study, brought upon him the gravel and stone ; of which he died on the 2d of March 1618, in the 58th year of his age; having filled the see only two years and three months. He wrote, 1. The Mirror of Popish Subtleties. Lond. 1594, 4to. 2. The Exaltation of the Kingdom and Priest¬ hood of Christ, sermons on the first seven verses of the 110th Psalm. Lond. 1601, 4to. 3.

ABBREVIATION, or Abbreviature, a contraction of a word or passage, made by dropping some of the let¬ ters, or by substituting certain marks or characters in their place. A late philosophical writer on grammar di¬ vides the parts of speech into words which are necessary for the communication of thought, as the noun and verb, and abbreviations which are employed for the sake of dis¬ patch. The latter, strictly speaking, are also parts of speech, because they are all useful in language, and each has a different manner of signification. Mr Tooke, how¬ ever, seems to allow* that rank only to the necessary * words, and to consider all others as merely substitutes of the first sort, under the title of abbreviations. They are employed in language in three ways—in terms, in sorts of words, and in construction. Mr Locke in his Essay on the Human Understanding treats of the first class ; numerous authors have written on the last; and for the second class of abbreviations, see the work of Mr Tooke entitled Diver¬ sions of Parley. * Lawyers, physicians, &c. use many ab- , breviations, for the sake of expedition. But the Rabbis are the most remarkable for this practice, so that their writings are unintelligible without the Hebrew abbrevia¬ tures. The Jewish authors and copyists do not content themselves with abbreviating words like the Greeks and Latins, by retrenching some of the letters or syllables; they frequently take away all but the initial letters. They even take the initials of several succeeding words, join them together, and, adding vowels to them, make a sort of barbarous words, representative of all those which they have thus abridged.

ABBREVIATORS, a college of 72 persons in the chan¬ cery of Rome, who draw up the pope’s brieves, and reduce petitions, when granted by him, into proper form for being converted into bulls. ABBS, St, a promontory on the eastern coast of Scot¬ land, Lat. 55.55. N. Long. 2. 8. 30. W. The shore around is steep and rocky, and there is a depth of 30 or 40 fathoms water not far from land. The tide runs by it with a strong current, and a little wind causes a great rolling sea. ABBUTALS signify the buttings or boundings of land towards any point. Limits were anciently distin¬ guished by artificial hillocks, which were called botemines; and hence butting. In a description of the site of land, the sides on the breadth are more properly adjacentes, and those terminating the length are abbutantes; which, in old surveys, were sometimes expressed by capitare, to head ; whence abbutals are now called head-lands. ABCEDARY, or Abcedarian, an epithet given to compositions, the parts of which are disposed in the order of the letters of the alphabet: thus we say, Abcedarian psalms, lamentations, hymns, &c.; such * are Psal. xxv. xxxiv. cxix. &c. ABCHASIEN, a province of the Asiatic Russian em¬ pire, on the border of the Black Sea, comprehended between Lat. 42. 30. and 44. 45. N., and between Long. 37. 3.'and 40. 36. E. The high mountains of Caucasus on the north and north-west divide it from Circassia; on the south-west it is bounded by Mingrelia; and on the south, south-west, and north-west by the Black Sea. The extent is about 5080 square miles. The climate is gene¬ rally mild, being defended from the northerly winds by the lofty range of mountains. The sea-coast is in many parts a sandy soil; but in many of the vallies which run up between the projections of the Caucasus the land is fertile, but better adapted for pasturage than for the growth of corn ; and hence the greater part of the inha¬ bitants are in the pastoral state. The grape and all other fruits come to perfection. Under the Turkish dominion the trifling commerce was with the Asiatic provinces of that power; but its course is now changed, and passes towards the north. The number of inhabitants is esti¬ mated at 56,500, of whom 40,000 are aboriginal. The Turcomans, Nogay Tartars, with the Greeks, Armenians, and Jews that occupy the towns and ports on the coast, are reckoned to be 15,000, and the Russians and Cossacks 1500. In early times the Abchasiens were heathens, but adopt¬ ed Christianity under the Emperor Justinian, who built a church to the Virgin Mary in 550, and sent missionaries. Under the Turks their Christianity gradually disappeared; and at present the higher classes adhere to Mahomedan- ism, whilst the mass of the people follow each a separate species of idolatry. Though by the peace of 1812 Rus¬ sia entered into all the rights enjoyed by the Turks, it scarcely interfered with the interior authority of the seve¬ ral chiefs, who by force gain the superiority; nor does it draw any revenue from the country, but is satisfied with possession of a few commanding fortresses, and with the trade which falls into the new channels from the effect of the political changes. A B D ABDALLA, the son of Abdalmotalleb, was the father Abdalla of the prophet Mahomet. He was the most beautiful I! and modest of the Arabian youth ; and when he married Abdallatif, Amina, of the noble race of the Zahrites, 200 virgins are^-*^"^ said to have died of jealousy and despair. Several other Arabians of eminence bore the same name. ABDALLATIF, or Abdollatiph, a celebrated phy¬ sician and traveller, and one of the most voluminous writers of the East, was born at Bagdad, in the 557th year of the Hegira, being the 1161st of the Christian era. Of the life of this learned person there has for¬ tunately been preserved a memoir, written by himself, together with some additions by a contemporary bio¬ grapher, named Osaiba. The whole of this curious piece has been translated into French, and published with a work of Abdallatif’s, of which we shall afterwards give some account. Long before the period of his birth, the empire of the Caliphs had begun to decline; but their capital still continued to enjoy those advantages for education which it had originally derived from their liberal patronage of learning and science. Abdallatif was carefully instructed in every branch of know¬ ledge then taught in that renowned city; and the bio¬ graphical piece just alluded to is not a little interest¬ ing, from the glimpses it affords of the studies which engaged the attention of the more aspiring of the Mus¬ sulman youth. After learning to read, the rules of grammar appear to have been studied with a degree of care and earnestness, which has not perhaps been equalled in any other coun¬ try. With the study of grammar was joined that of the Koran and the traditionary doctrines, and the whole of the sacred book was carefully committed to memory. This faculty seems, indeed, to have been severely taxed ; for it was also thought necessary to be able to repeat several treatises on grammar and jurisprudence, besides some of the choicer collections of Arabian poetry. In these arduous exercises, Abdallatif says that he was for a considerable time accustomed to pass the greater part of the night. Having attained to great proficiency in the usual studies, he afterwards applied to the natural philosophy of that day, and to medicine ; and with the view of still further improving himself by converse with the learned of other places, he set out, when in his twenty-eighth year, to Mosul in Mesopotamia. Having resided about a year in this city, he next proceeded to Damascus, then a place of great resort to the learned of the surrounding coun¬ tries. Abdallatif found here many of the most eminent men of that age, part of whom were busied in the chime¬ rical pursuits of the Hermetic art, and part in philologi¬ cal and speculative inquiries. He seems always to have entertained great contempt for the sort of chemistry then in vogue, but he entered with eagerness into speculative discussions ; and he at this time composed a treatise upon the Divine essence and attributes, in consequence of some discussions with Alkendi, a philosopher of eminence, who was not, however, thought to be quite orthodox in his faith. The active curiosity of Abdallatif was next directed to Egypt; and he accordingly proceeded to Acre, where its sultan, the great Saladin, was at the time encamped, in order to solicit his permission to visit that country. This monarch was a liberal protector of the learned, and fond of their conversation ; but having been lately defeated by the crusaders under Richard Cceur de Lion, he was too much occupied with the cares consequent upon this dis¬ aster, to admit Abdallatif to the expected honour of a personal interview. He was, however, received in a A £ D A B D 21 Abdallatif. courteous manner by the Vizier A1 Fadhel, whom he found in his tent writing and dictating at the same time to two secretaries; employments which he continued whilst he conversed with his visitor upon sundry points of grammar and philology. Having obtained the neces¬ sary credentials from this minister, he proceeded to Cairo; and the munificence which Saladin and his courtiers ex¬ tended towards the learned, was strikingly exemplified in his reception and treatment in that city. He was pro¬ vided with a house, with provisions, and money; and the vizier seldom failed to recommend him anew, in those letters of business which he had occasion to write to the governor of the place. Here Abdallatif enjoyed the long wished for opportu¬ nity of conversing with that Eagle of the Doctors, as he was called, the celebrated Maimonides, who had been for a considerable time settled in Egypt, and was physi¬ cian to the sultan. Here, too, he was fortunate enough to meet with a sage, who weaned him of his admiration for the writings of Avicenna, by pointing out the supe¬ rior value of the ancients. But the philosophers of Grand Cairo were not all of this stamp ; for some of them were pretenders to the transmutation of metals, and one boast¬ ed that his art enabled him to fabricate a tent of the waters of the Nile. Having passed a considerable time in making various observations and collections in this in¬ teresting city, Abdallatif set out for Jerusalem, on learn¬ ing that he would there see Saladin, who had at length concluded a truce with the crusaders. Saladin received him with every mark of respect for his talents, and bestowed upon him a pension. He was then busied in repairing the walls of the Holy City, him¬ self, says Abdallatif, often carrying stones upon his shoul¬ ders, to animate the undertaking. But in spite of all his cares and projects, he daily conversed with the learned men whom his bounty had drawn around him. Abdalla¬ tif mentions, that when first introduced, he found him in the midst of a circle of this description; and he adds, that upon all the various subjects which were discussed, the sultan spoke with the most agreeable address, as well as ingenuity. From Jerusalem, Abdallatif returned to Damascus; and, after a considerable interval, a fresh opportunity having occurred of revisiting Egypt, he again proceeded to Cairo, where he taught medicine and philo¬ sophy for several years. During this period, Egypt w'as visited with a terrible famine and pestilence, of which, and the horrors and crimes which ensued, he has given a most appalling de¬ scription in the two last chapters of his Account of this country. Human nature was scarcely ever presented to observation under so hideous an aspect; the wretched Egyptians were driven, not only to feed upon the bodies of those who had fallen victims to want or disease, but to seize upon children, whom they killed and devoured; and Abdallatif asserts, that they thus cam# to acquire such a relish for those inhuman repasts, that they with difficulty refrained from them after the famine had subsided. It was likewise during his second stay in Egypt that he wit¬ nessed an insane attempt to pull down the Pyramids ; a project to which the reigning sultan (a son of Saladin’s, who, after his death, succeeded to this part of his domi¬ nions) had been instigated by some of his favourites, and in which he persisted for eight months, without being able to make any sensible impression upon these inde¬ structible monuments of the ancient world. About the year 1207, Abdallatif left Egypt for his for¬ mer residence, Damascus; and here he for some time practised as a physician, and lectured upon medicine with great success. But his love of new scenes, and desire of extending his knowledge and fame, still urged him to tra- Abdallatif vel; and he seems to have passed the rest of his life in || Aleppo, and various parts of Armenia and Asia Minor, Abdalma- acquiring both wealth and glory by his abilities as a phy- ^elc* sician and an author. Having returned to his native city, purposing to present some of his works to the caliph, and then to set out on a pilgrimage to Mecca, he was seized with illness soon after his arrival, and died1 there in the year 1231. He was undoubtedly a person of great knowledge, and of an ardent, inquisitive, and penetrating mind. Accord¬ ing to his Arabian biographer, to whom he was well known, he showed himself, in conversation, somewhat vain of his own attainments; and was accustomed to speak rather scornfully of most of his contemporaries. But it ought to be mentioned, to the credit of his understanding, that his derision seems partly to have flowed from his contempt of those chemical fooleries to which they were so much addicted, that, to use the words of Gibbon, “ the reason and the fortune of thousands were evaporated in the crucibles of Alchemy.” Of that long list of treatises on medicine, philosophy, and literature, which Osaiba has appended to the account of Abdallatif’s life, one only has found its way into Europe; nor do any of the others appear to be known at this day in the East. The work here alluded to is his Account of Egypt, which was fortunately discovered and brought to this country by our celebrated orientalist Pococke. The manu¬ script, which is a very old one, is still preserved in the Bodleian Library. Of this work, an elegant edition, with a Latin translation, notes, and a life of Abdallatif, was published in 1800, by Dr White, professor of Arabic in the University ofx Oxford. A French translation, with enlarged notes, was published at Paris in 1810, by M. Silvestre de Sacy ; and to this, among other valuable illus¬ trations, is appended a translation from an Arabic manu¬ script, of the curious biographical memoir to which we have above alluded. This account of Egypt consists of two books ; the first of which, in six chapters, gives a general view' of the country, of its plants, animals, antiquities, buildings, and modes of navigating on the Nile ; and the second, in three chapters, treats at large of this river, and of that terrible famine already mentioned, which was occasioned by a failure in the usual annual increase of its waters. The book undoubtedly is, upon the whole, one of the most interesting productions which has come to us from the East; inasmuch as it presents us with a detailed and au¬ thentic view of the state of Egypt during the middle ages, and thus supplies a link which was wanting between the accounts of ancient and of modern times.

ABDALMALEK, the son of Mirvan, and the fifth ca¬ liph of the race of the Ommiades. He surpassed all his predecessors in power and dominion; for in his reign the Indies were conquered in the east, and his armies pe¬ netrated Spain in the west: he likewise extended his em¬ pire toward the south, by making himself master of Me¬ dina and Mecca. Under his reign the Greek language and character were excluded from the accounts of the public revenue. If this change, says Gibbon, w'as pro¬ ductive of the invention or familiar use of the Arabic or Indian ciphers, which are our present numerals, a regu¬ lation of office'has promoted the most important discove¬ ries of arithmetic, algebra, and the mathematical sciences. He began his reign in the 65th of the Hegira, A. b. 684; 22 A B D Abdalma- reigned 15 years; and four of his sons successively en- laU j°yed the caliphate. Abdalmalek. See Avenzoar. ABDALONYMUS, or Abdolonymus, in classic his¬ tory, of the royal family of Sidon, and descended from King Cinyras, lived in obscurity, and subsisted by culti¬ vating a garden, while Strato was in possession of the -crown of Sidon. Alexander the Great having deposed Strato, inquired whether any of the race of Cinyras was living, that he might set him on the throne. It was ge¬ nerally thought that the whole race was extinct; but at last Abdalonymus was thought of, and mentioned to Alexan¬ der, who immediately ordered some of his soldiers to fetch him. I hey found the good man at work, happy in his poverty, and entirely a stranger to the noise of arms, with which all Asia was at that time disturbed; and they could scarcely persuade him they were in earnest. Alexander was convinced of his high descent by the dignity of his person; and not only bestowed on him all that belonged to Strato, but augmented his dominions, and gave him a large present out of the Persian spoils. ABDALS, in the eastern countries, a kind of saints supposed to be inspired to a degree of madness. The word is perhaps derived from the Arabic, Abdallah, the servant of God. Hurried on by excess of zeal, especially in the Indies, they often run about the streets, and kill all they meet who are of a different religion. The English sailors call this running a muck, from the name of the in¬ strument, a sort of poniard, which they employ on those desperate occasions. If they are killed, as it commonly happens before they have done much puschief, they reckon it highly meritorious ; and are esteemed, by the vulgar, martyrs for their faith. ABDERA, in Ancient Geography, a maritime town of Thrace, not far from the mouth of the river Nessus, on the east side. The Abderites, or Abderitani, were very much derided for their want of wit and judgment: yet their city has given birth to several eminent persons ; as Protagoras, Democritus, Anaxarchus, Hecataeus the his¬ torian, Nicenaetus the poet, and many others, who were mentioned among the illustrious men. In the reign of Lysimachus, Abdera was afflicted for some months with ^ucianus, a most extraordinary disease :x this was a burning fever, quomodo whose crisis was always on the seventh day, and then it left them; but it so distracted their imaginations, that they fancied themselves players. After this, they were ever repeating verses from some tragedy, and particularly from the Andromeda of Euripides, as if they had been upon the stage ; so that many of these pale meagre actors were pouring forth their tragic exclamations m every street. This delirium continued till the winter following ; which was a very cold one, and therefore fitter to remove it. Lucian, who has described this disease, endeavours to account for it in this manner : Archelaus, an excellent player, acted the Andromeda of Euripides before the Ab¬ derites, in the height of a very hot summer. Several had a fever at their coming out of the theatre ; and as their imaginations were full of the tragedy, the delirium which the fever raised perpetually represented Andromeda, Per¬ seus, Medusa, &c. and the several dramatic incidents, and called up the ideas of those objects, and the pleasure of the representation, so strongly, that they could not for¬ bear imitating Archelaus’s action and declamation: And from these the fever spread to others by infection. * ABDERAHMA, a Saracen viceroy in Spain, who re¬ volted and formed an independent principality at Cordova. He had several successors of the same name. A viceroy and captain-general of this name led the Saracens and their followers into France, ravaging the country wherever Hist, sit conscriben dus initio. A B D they came. At length he was met at Tours by Charles Abdest Martel, who had received reinforcements of Germans |[ and Gepidae; and after many skirmishes, the Saracen Abduction, army, in a general action, was totally routed, and Abder- ahma was killed, with 370,000 Moors. This great event, which first broke the power of the Saracens, and taught the Europeans that they were not invincible, happened about the year 732 of the Christian era, and of the He¬ gira 114. ABDEST, a Persian word, properly signifying the wa¬ ter placed in a basin for washing the hands ; but it is used to imply the legal purifications practised by the Maho¬ metans before prayer, entering the mosque, or reading the Alcoran. ABDIAS of Babylon, one of the boldest legend- writers, who boasted that he had seen Christ, that he was one of the 70 disciples, had been eye-witness of the ac¬ tions and prayers of several of the apostles at their deaths, and had followed into Persia St Simon and St Jude, who, he said, made him the first bishop of Babylon. His book, entitled Historia Certaminis Apostolici, was published by Wolfgang Lazius, at Basil, 1551; and has passed through several editions in other places. ABDICATION, the action whereby a person in office renounces and gives up the same before the term of ser¬ vice is expired. This word is frequently confounded with resignation ; but differs from it: for abdication is done purely and simply, whereas resignation is in favour of some third person. In this sense, Dioclesian is said to have abdi¬ cated the crown; Philip IV. of Spain resigned it. It is said to be a renunciation, quitting, and relinquishing, so as to have nothing further to do with a thing; or the doing of such actions as are inconsistent with the holding of it. On King James’s leaving the kingdom, and abdi¬ cating the government, the lords proposed that the word desertion should be employed ; but the commons thought that it was not sufficiently comprehensive. Among the Roman writers it is more particularly used for the act whereby a father discarded or disclaimed his son, and ex¬ pelled him the family. It is distinguished from exhcere- datio or disinheriting, in that the former was done in the father’s lifetime ; the latter, by will at his death : so that whoever was abdicated, was also disinherited; but not vice versa.

E. ^ ABDUCTION,in Logic, a kind of argumentation, by the Greeks called apagoge, wherein the greater extreme is evidently contained in the medium, but the medium not so evidently in the lesser extreme as not to require some further medium or proof to make it appear. It is called abduction, because, from the conclusion, it draws us on to prove the proposition assumed. Thus, in the syllogism, “ All whom God absolves are free from sin; but God absolves all who are in Christ; therefore all who are in Christ are free from sin,”—the major is evident; but the minor, or assumption, is not so evident without some other proposition to prove it, as, “ God received full satisfaction for sin by the sufferings of Jesus Christ.” ABE Abductor ABDUCTOR, or Abducent, in Anatomy, a name given )| to several of the muscles, on account of their serving to Abelard, withdraw, open, or pull back the parts to which they be- long.

ABEJAR, a town in the province of Soria, in Old Cas¬ tile, in Spain. ABEL, second son of Adam and Eve, was a shepherd. He offered to God some of the firstlings of his flock, at the same time that his brother Cain offered the fruits of the earth. God was pleased with Abel’s oblation, but dis¬ pleased with Cain’s ; which so exasperated the latter, that he rose up against his brother and killed him. These are the only circumstances Moses relates of him. It is re¬ markable, that the Greek churches, who celebrate the feasts of every other patriarch and prophet, have not done the same honour to Abel. His name is not to be found in any catalogue of saints or martyrs till the 10th century ; nor even in the new Roman martyrology. However, he is prayed to, with some other saints, in several Roman litanies said for persons who lie at the point of death. Abel-Keramin, or Vinearum, beyond Jordan, in the country of the Ammonites, where Jephthah defeated them, seven miles distant from Philadelphia, abounding in vines, and hence the name.

ABELARD, Peter, an eminent scholastic philosopher of France, of noble descent, was born at Palais near Nantes in Bretagne, in the year 1079. Devoted to letters by his father’s appointment, and by his own inclination, his liter¬ ary attainments could at this time only be exhibited in the field of scholastic philosophy ; and, that he might be fitted for his destined career of life, he was placed, after a pre¬ vious course of grammatical studies, under the tuition of Rosceline, a celebrated metaphysician, and founder of the sect of the Nominalists. Under the instructions of this able master, at the early age of sixteen, he furnished him¬ self with a large store of scholastic knowledge, and acquir¬ ed a subtiltyand quickness of thought, a fluency of speech, and facility of expression, which were necessary qualifica¬ tions in scholastic disputation. Having spent some time in visiting the schools of seve¬ ral provinces, in the twentieth year of his age he fixed his residence in the university of Paris, then the first seat of learning in Europe. The master, William de Cham- peaux, was at that time in high repute for his knowledge of philosophy, and his skill in the dialectic art; to him he committed the direction of his studies, and was at first contented with receiving instruction from so eminent a preceptor. De Champeaux was proud of the talents of his pupil, and admitted him to his friendship. But the aspiring youth ventured to contradict the opinions of his master, and in the public school held disputations with him, in which he was frequently victorious. The jealousy ABE 23 of the master and the vanity of the pupil naturally occa- Abelard, sioned a speedy separation. Elated by success, and confident of his own powers, Abelard, without hesitation, at the age of twenty-two, opened a public school of his own. Melun, a town ten leagues from Paris, where the court frequently resided, was the place which lie chose for this bold display of his talents. But it was not without considerable difficulty that Abelard executed his plan ; for De Champeaux, who regarded him as a rival, openly employed all his interest against him. Abelard at length prevailed, his school was opened, and his lectures were attended by crowded and admiring auditories. Emboldened by this success, and perhaps stimulated by unworthy resentment, Abelard re¬ solved to maintain an open contest with his master, and for this purpose removed his school to Corbeil near Paris. The disputants frequently met in each other’s schools; and the contest was supported on each side with great spirit, amidst crowds of their respective scholars. The young champion was in the end victorious, and his anta¬ gonist was obliged to retire. Constant application and violent exertions had now so far impaired Abelard’s health, that it was become neces¬ sary for him to interrupt his labours ; and, with the advice of his physician, he withdrew to his native country. Two years afterwards, he returned to Corbeil, and found that De Champeaux had taken the monastic habit among the regular canons in the convent of St Victor; but that he still continued to teach rhetoric and logic, and to hold public disputations in theology. Returning to the charge, he renewed the contest, and his opponent was obliged to acknowledge himself defeated. The scholars of De Cham¬ peaux deserted him, and went over in crowds to Abelard. Even the new professor, who had taken the former school of De Champeaux, voluntarily surrendered the chair to the young philosopher, and requested to be enrolled among his disciples. A triumph so complete, while it gratified the vanity of Abelard, could not fail to provoke the resentment of his old master, who had influence to obtain the appoint¬ ment of a new professor, and drive Abelard back to Melun. De Champeaux’s motive for this violent proceeding was soon perceived ; even his friends were ashamed of his con¬ duct ; and he retired from the convent into the country. When Abelard was informed of the flight of his adversary, he returned towards Paris, and took a new station at the abbey on Mount St Genevieve. His rival, the new pro¬ fessor, was unequal to the contest, and was soon deserted by his pupils, who flocked to the lectures of Abelard. De Champeaux, too, returning to his monastery, renewed tire struggle; but so unsuccessfully, that Abelard was again victorious. During a short absence, in which Abelard visited his native place, De Champeaux was preferred to the see of Chalons. The long and singular contest between these philosophers terminated; and Abelard, perhaps for want of a rival to stimulate his exertions, or possibly through envy of the good fortune of his rival, determined to exchange the study and profession of philosophy for that of theology. He therefore quitted his school at St Genevieve, and removed to Laon, to become a scholar of Anselm. From this celebrated master he entertained high expectations ; but they were soon disappointed. On at¬ tending his lectures, he found that, though he possessed uncommon fluency of language, he left his auditors with¬ out instruction. Abelard gradually retired from these unprofitable lectures, but without offering offence either to the veteran professor or his scholars. In conversation one of them asked him, what he thought of the study of the Scriptures ? Abelard replied, that he thought the ex- 24 ABE Abelard, planation of them a task of no great difficulty; and to prove his assertion, he undertook to give a comment, the next day, upon any part of the Scriptures they should mention. They fixed upon the beginning of the prophecy of Ezekiel; and the next morning he explained the pas¬ sage in a theological lecture, which was heard with admi¬ ration. For several successive days, the lectures were, at the request of the»audience, continued ; the whole town pressed to hear them ; and the name of Abelard was echo¬ ed through the streets of Laon. Anselm, jealous of the rising fame of this young theologian, prohibited his lec¬ tures, under the pretence that so young a lecturer might fall into mistakes, which would bring discredit upon his master. Abelard, whose ambition required a wider field than that of Laon, obeyed the prohibition, and withdrew. He returned to Paris, whither the fame of his theological talents had arrived before him, and opened his school with his lectures on the prophecy of Ezekiel. His auditors were delighted; his school was crowded with scholars ; and he united in his lectures the sciences of theology and philosophy with so much success, that multitudes repair¬ ed to him from various parts of France, from Spain, Italy, Germany, Flanders, and Great Britain. Hitherto Abelard has appeared with high distinction, as an able disputant, and a popular preceptor: we must now view him under a different character, and when near¬ ly arrived at the sober age of forty, see him, on a sudden, exchanging the school of philosophy for the bower of pleasure, and even disgracing himself, as will too plainly appear in the sequel, by forming and executing a deli¬ berate plan for the seduction of female innocence. It happened that there was at this time, resident in Paris, Pleloise, the niece of Fulbert, one of the canons of the cathedral church, a lady about eighteen years of age, of great personal beauty, and highly celebrated for her lite¬ rary attainments. Abelard, whose vanity had been satiat¬ ed with fame, and the vigour of whose mind was now en¬ ervated by repose, found himself inclined to listen to the voice of passion. He beheld with ardent admiration the lovely Heloise, and confident that his personal attractions were still irresistible, he determined to captivate her af¬ fections. Fulbert, who doubtless thought himself ho¬ noured by the visits of so eminent a scholar and philoso¬ pher, received him into his house as a learned friend. He was soon afterwards prevailed upon, by a handsome pay¬ ment which Abelard offered for his board, to admit him into his family ; and, apprehending no hazard from a man of Abelard’s age and profession, requested him to under¬ take the instruction of Heloise. Abelard accepted the trust, but, as it seems, without any other intention than to betray it. The hours of instruction were employed in other lessons than those of learning and philosophy ; but Fulbert’s respectful opinion of the philosopher, and his partiality for his niece, long concealed from him an amour, which was become the subject of general conversation. Upon discovering her pregnancy, it was thought neces¬ sary for her to quit her uncle’s house ; and Abelard con¬ veyed her to Bretagne, where his sister was prepared to receive them. Here Heloise was delivered of a son, to whom they gave the whimsical name of Astrolabus. Abe¬ lard, upon the birth of the child, proposed to Fulbert to marry his niece, provided the marriage might be kept secret: Fulbert consented, and Abelard returned to Bre¬ tagne to fulfil his engagement. Heloise, partly out of re¬ gard to the honour of Abelard, whose profession bound him to celibacy, and partly from a romantic notion that love like hers ought not to submit to ordinary restraints, at first gave Abelard a peremptory refusal. He, however, at last prevailed, and they were privately married at Pa- A B E ris. Heloise from this time met with severe treatment Abelard, from her uncle, which furnished Abelard with a plea for removing her from his house, and placing her in the abbey of Benedictine nuns, in which she had been educated. Fulbert concluded, perhaps not without reason, that Abe¬ lard had taken this step, in order to rid himself of an en¬ cumbrance which obstructed his future prospects. Deep resentment took possession of his soul, and he meditated revenge. He employed several ruffians to enter his chamber by night, and inflict upon his person a disgrace¬ ful and cruel mutilation. The deed was perpetrated ; the ruffians were taken, and suffered, according to the Lex Talionis, the punishment they had inflicted; and Ful¬ bert, for his savage revenge, was deprived of his benefice, and his goods were confiscated. Unable to support his mortifying reflections, Abelard resolved to retire to a convent. At the same time he formed the selfish resolu¬ tion, that, since Heloise could no longer be his, she should never be another’s, and ungenerously demanded from her a promise to devote herself to religion ; and even insisted upon her taking the holy vow before him, suspecting, as it seems, that if he first engaged himself, she might violate her promise, and return to the world. A few days after Heloise had taken her vows, Abelard assumed the monastic habit in the abbey of St Denys, determined, as it seems, to forget, in hope of being for-* gotten by the world. However, his admirers and scholars in Paris were unwilling that the world should lose the benefit of his labours, and sent deputies to entreat him to return to his school. After some deliberation, he again yielded to the call of ambition; and at a small village in the country, he resumed his lectures, and soon found himself surrounded with a numerous train of scholars. The revival of his popularity renewed the jealousy of other professors, who took the first opportunity of bring¬ ing him under ecclesiastical censure. A treatise which he published at this time, entitled, The Theology of Abelard, was supposed to contain some heretical tenets. A synod was called at Soissons in the year 1121 ; the work was condemned to be burnt, and Abelard was com¬ manded to throw it into the flames. After being involved in other controversies, new charges were brought against him, and he fled to the convent of St Ayoul at Provins in Champagne, the prior of which wras his intimate friend. The place of his retreat was soon discovered, and threats and persuasions were in vain employed to recall him : at last he obtained permission to retire to some solitary re¬ treat, on condition that he should never again become a member of a convent. The spot which he chose was a vale in the forest of Champagne, near Nogent upon the Seine. Here Abelard, in 1122, erected a small oratory, which he dedicated to the Trinity, and which he afterwards enlarged, and con¬ secrated to the Third Person, the Comforter, or Paraclete. Here he was soon discovered, and followed by a train of scholars. A rustic college arose in the forest, %nd the number of his pupils soon increased to six hundred. Jea¬ lousy again provoked the exertions of his enemies, and he was meditating his escape, when, through the interest of the duke of Bretagne, and with the consent of the abbot of St Denys, he was elected superior of the monastery of St Gildas, in the diocese of «Vannes, where, though not without frequent and grievous vexations, he remained se¬ veral years. About this time, Suger, the abbot of St Denys, on the plea of an ancient right, obtained a grant for annexing the convent of Argenteuil, of which Heloise was now prioress, to St Denys; and the nuns, who were accused of irregular practices, were dispersed. Abelard, informed of the dis- ABE Abelard tressed situation of Heloise, invited her, with her com¬ il panions, eight in number, to take possession of the Pa- Abella. raclete. / It was during Abelard’s residence at St Gildas that the interesting correspondence passed between him and He¬ loise, which is still extant. The letters of Heloise, in this correspondence, abound with proofs of genius, learn¬ ing, and taste, which might have graced a better age. It is upon these letters that Mr Pope has formed his celebrated Epistle from Eloisa to Abelard. Here, too, Abelard probably wrote his Theology, which again sub¬ jected him to persecution. His opinions were pronounced heretical by a council; and although he appealed to Rome, the judgment of the council was confirmed by the pope; and he was sentenced, unheard, to perpetual silence and imprisonment. By the interposition of some friends, however, and by a submissive apology, he obtain¬ ed his pardon, with permission to end his days in the mo¬ nastery of Cluni. At Cluni he was retired, studious, and devout. The monks of the convent importuned him to resume the busi¬ ness of instruction. In a few occasional efforts he com¬ plied with their solicitations ; and his lectures were heard with undiminished applause. But his health and spirits were much enfeebled, and gradually declined till he died in the 63d year of his age, A. d. 1142. His body was sent to Heloise to be interred in the convent of the Pa¬ raclete. Heloise survived her husband 21 years, a pattern of conjugal affection and monastic virtue ; and was buried in the same grave. The writings of Abelard will not give the reader a high idea of his genius or taste ; but it can¬ not be questioned, that the man who could foil the first masters of the age at the weapons of logic, draw round him crowded and admiring auditors, and collect scholars from different provinces and countries wherever he chose to form a school, must have possessed extraordinary ta¬ lents. Had his love of truth been equal to his thirst of fame, and had his courage in adhering to his principles been equal to his ingenuity in defending them, his suffer¬ ings and persecutions might have excited more regret, and his title to honourable remembrance would have been better established. His principal works, written in Latin, are, An Address to the Paraclete on the Study of the Scriptures ; Problems and Solutions; Sermons on the Festivals; A Treatise against Heresies; An Exposition of the Lord’s Prayer; A Commentary on the Romans; A System of Theology; and his Letters to Heloise and to others. Of some of those letters, and the answers, there are translations in Bonnington's History of the Lives of Abelard and Heloise. The best Latin edition is that of Rawlinson, London, 1716, 8vo. ABELIANS, Abeolites, or Abelonians, in church history, a sect of heretics mentioned by St Austin, which arose in the diocese of Hippo in Africa, and is supposed to have begun in the reign of Arcadius, and ended in that of Theodosius. Indeed it was not calculated for being of any long continuance. Those of this sect regu¬ lated marriage after the example of Abel; who, they pre¬ tended, was married, but died without ever having known his wife. They therefore allowed each man to marry one woman, but enjoined them to live in continence ; and, to keep up the sect, when a man and woman entered into this society, they adopted a boy and a girl, who were to inherit their goods, and to marry upon the same terms of not begetting children, but of adopting two of different sexes.

He was also a perfect master of the Arabic. His principal work is, Commen¬ taries on the Old Testament, which is much esteemed: these are printed in Bomberg’s and Buxtorf’s Hebrew Bibles. His style is clear, elegant, concise, and much like that of the Holy Scriptures: he almost always ad¬ heres to the literal sense, and everywhere gives proofs of his genius and good sense; he, however, advances some erroneous sentiments. The scarcest of all his books is entitled Jesud Mora, which is a theological work, in¬ tended as an exhortation to the study of the Talmud.

ABERBROTHICK, or Arbroath, a seaport town of Scotland, in the county of Angus, situated at the dis¬ charge of the little river Brothic into the sea, as the name imports, Aber in the British implying such a situation. It is a flourishing place, well built, and still increasing. Having been in an improving state for the last forty years, it has now a considerable trade, and employs about 6000 tons of shipping, chiefly in the importation of flax, the raw material of its manufactures; of flax-seed, tim¬ ber, iron, &c. from the Baltic. The chief employment of the inhabitants is the spinning of flax by machinery, D 26 ABE Aberbro- and its subsequent manufacture into sheetings. A consi- thick derable coasting trade is carried on to London and to the II ports on the east coast of England, as well as to Leith Abercrora- anc] ^}le other ports in the frith of Forth. At this place, in default of a natural harbour, an artificial one of piers has been formed, where, at spring tides, which rise here fifteen feet, ships of two hundred tons can come, and of eighty at neap tides ; but they must lie dry at low water. Its chief fault is that it is small, and offers no re¬ fuge from the German Ocean in easterly storms, though it is capable of improvement, and, with some expense, might be rendered secure. A battery, which was erected for its defence in 1781, in consequence of an attack from a French privateer, has since been dismantled. This port is of great antiquity: there is an agreement yet extant between the abbot and the burghers of Aberbrothick, in 1194<, concerning the making of the harbour. Both parties were bound to contribute their proportions ; but the largest fell to the share of the former, for which he was to receive an annual tax payable out of every rood of land lying within the borough. The glory of this place was the abbey, whose very ruins give some idea of its former magnificence. It was founded by William the Lion in 1178, and dedicated to our celebrated primate Thomas a Becket. The founder was buried there; but there are no remains of his tomb, or any other, excepting that of a monk of the name of Alexander Nicol. The monks were of the Tyronensian order; and were first brought from Kelso, whose abbot declared those of this place, on the first institution, to be free from his jurisdic¬ tion. The last abbot was the famous Cardinal Beaton, at the same time archbishop of St Andrews, and, before his death, as great and absolute here as Wolsey was in Eng¬ land. King John, the English monarch, granted this monastery most uncommon privileges; for, by charter under the great seal, he exempted it a teloniis et consue- tudine in every part of England, except London. At Aberbrothick is a chalybeate water, similar to those of Peterhead and Glendye. The only public buildings worthy of notice, besides the ruins of the abbey, are the parish church and chapels of ease, the town-house, the public schools, and the signal tower which communicates with the Bell Rock light-house at 12 miles distance in the German Ocean. Arbroath is a royal burgh, and unites with Aberdeen, Bervie, Montrose, and Brechin, in send- / ing a member to the British parliament. 58 miles N.N.E. of Edinburgh.

ABERCROMBY, The Honourable Alexander (Lord Abercromby), a Judge in the Courts of Session and Justiciary in Scotland, was the youngest son of George Abercromby, of Tullibody, Esq. of a respectable family in Clackmannanshire, and was born on the 15th October 1745. Mr Abercromby was early destined for the profession of the law, and with this view he was educated at the univer¬ sity of Edinburgh, where he passed through the requisite course of languages, philosophy, and law, and was admitted advocate in the year 1766. In 1780 he resigned the office ABE of sheriff-depute of Stirlingshire, which he had held for Abercrcm several years, and accepted of that of depute-advocate, by. with the hope of extending his employment in the line ofv'-^'v'v' his profession. In this step he was not disappointed ; for his reputation and business rapidly increased, and soon raised him to the first rank at the Scotch bar. But he still retained a taste for the elegant amusements of polite literature, and was one of that society w ho set on foot two periodical papers, the Mirror and Lounger, published at Edinburgh; the former in 1779, and the latter in 1785. To the Mirror he contributed ten papers, and to the Lounger nine. The names of the authors have been pub¬ lished in the late editions of these works, which renders it unnecessary to point out those papers of which Mr Abercromby was the author. In May 1792, he was ap¬ pointed one of the Judges of the Court of Session, and in December following he was called to a seat in the Court of Justiciary. Lord Abercromby continued to discharge the arduous duties of these important offices till summer 1795, when he was seized with a pectoral complaint, of which he died on the 17th November the same year, at Exmouth in Devonshire, where he had gone for the re¬ covery of his health. Abercromby, Sir Ralph, knight of the Bath, arid a lieutenant-general in the British army, an elder brother of the preceding, was born in the year 1738. Being destined for the army, he obtained, in May 1756, a cornet’s com¬ mission in the 2d dragoon guards ’; and rose, April 24. 1762, to the rank of a captain in the 3d regiment of horse. Ascending through the intermediate gradations of rank, he was appointed, November 3. 1781, to the colonelcy of the 103d infantry. September 28. 1787, he was promoted to the rank of major-general. November 5. 1795, he ob¬ tained the command of the 7th regiment of dragoons. Having been nearly 40 years in the army, having served with honour in two wars, and being esteemed one of the ablest, coolest, and most intrepid officers in the whole British forces, he was employed on the continent under his Royal Highness the Duke of York, in the com¬ mencement of the war against the French republic. In the action on the heights of Gateau, he commanded the advanced guard, and was wounded at Nimeguen. He conducted the march of the guards from Deventer to 01- densal, in the retreat of the British out of Holland, in the winter of 1794-5. In August 1795, he was appointed to succeed Sir Charles Gi*ey, as commander-in-chief of the British forces in the West Indies. March 24.1796, Grena¬ da was suddenly attacked and taken by a detachment of the army under his orders. He afterwards obtained pos¬ session of the settlements of Demerara and Essequibo, in South America. St Lucia was next taken by more diffi¬ cult exertions, in which his ability was signally displayed. St Vincent was, by the middle of June, added to the British conquests. Trinidad, in February 1797, shared the same fate. He returned the same year to Europe, and, in reward for such important services, was invested with the red ribbon, appointed to the command of the regi¬ ment of Scots Greys, intrusted with the governments of the Isle of Wight, Fort George, and Fort Augustus, and raised to the rank of lieutenant-general. ^He held, for a time, the chief command of the forces in Ireland. Ip that command, he laboured to maintain the discipline of the army, to suppress the rising rebellion, and to protect the people from military oppression, with a care worthy alike of the great general and the enlightened and benefi¬ cent statesman. From that station he was called to the chief command of the forces in Scotland. When the en¬ terprise against Holland was resolved upon, Sir Ralph Abercromby was called again to command, under his ibercrom- by II ' Aberdeen. ABE Royal Highness the Duke of York. The difficulties of the ground, the inclemency of the season, delays, though inconvenient, yet unavoidable, the disorderly movements of the Russians, and the timid duplicity of the Dutch, dis¬ appointed our hopes of that expedition. But by the Dutch, the French, the British, it was confessed, that even victory the most decisive could not have more con¬ spicuously proved the talents of this distinguished officer. His country applauded the choice, when, in 1801, he was sent with an army to dispossess the French of Egypt. His experience in Holland and Flanders, and in the cli¬ mate of the West Indies, particularly fitted him for this new command. He accomplished some of the first duties of a general, in carrying his army in health, in spirits, and with the requisite intelligence and supplies, to the des¬ tined scene of action. The landing, the first dispositions, the attack, and the superiority over the French which the British infantry under his command evinced, all bear tes¬ timony to the high military talents of this commander. It was his fate to fall in the moment of victory. General Lord Hutchinson, who succeeded him in the command, in the dispatches with the account of his death, has given a fine eulogium on his character as a soldier, and strongly expressive of the high estimation in which he was held by the army.—“ We have sustained an irreparable loss in the person of our never sufficiently to be lamented com¬ mander-in-chief, Sir Ralph Abercromby, who was mortally wounded in the action, and died on the 28th of March. I believe he was wounded early, but he concealed his si¬ tuation from those about him, and continued in the field, giving his orders with that coolness and perspicuity which had ever marked his character, till long after the action was over, when he fainted through weakness and loss of blood. Were it permitted for a soldier to regret any one who has fallen in the service of his country, I might be excused for lamenting him more than any other person ; but it is some consolation to those who tenderly loved him, that, as his life was honourable, so was his death glorious. Flis memory will be recorded in the annals of his country—will be sacred to every British soldier—and embalmed in the recollection of a grateful posterity.” His remains were conveyed on board Admiral Lord Keith’s flag-ship to Malta, attended by Colonel Sir John Dyer, and were interred in the commandery of the grand master, with the highest military honours. A monument to his memory was erected in St Paul’s church, London, in pursuance of a vote of the House of Commons. His widow was created a peeress, and a pension of L.2000 a-year for her and three lives settled on the family. {Gent. Mag.) ABERDEEN, Old, is a place of great antiquity. Ac¬ cording to tradition, it was of note in the reign of Gre- gory, who conferred on it some privileges about the year 898. In 1004i, Malcolm II. founded a bishopric at a place called Mortlich in Banffshire, in memory of a signal vic¬ tory which he there gained over the Danes: which bishopric was translated to Old Aberdeen by David I.; and in 1153, the then bishop of Aberdeen obtained a new charter from Malcolm IV. There is extant a charter of Alexander II. by which, in 1217, the king grants to Aber¬ deen the same privileges he had granted to his town of 1 erth.^ Ihe town lies about a mile to the north of the New iown, at the mouth of the river Don, over which is a fine Gothic bridge, of a single arch, greatly admired, which rests on a rock on each side. This arch, said to have been built by a bishop of Aberdeen about the year 1290, is 67 feet wide at the bottom, and 34|- feet high above the surface of the river, which at ebb tide is here 19 feet deep. This town, which consists chiefly of one long street, was formerly the seat of the bishop, and had a ABE 27 large cathedral commonly called St Machar’s. Two very Aberdeen, antique and lofty spires of stone, and the nave, which is' used as a church, are now the only remains of it. They are finely ornamented, and are in a state of complete re¬ pair. The bishopric was founded in the time of David I. above mentioned. The cathedral had anciently two rows of stone pillars across the church, and three turrets ; the steeple, which was the largest of these turrets, rested upon an arch, supported by four pillars. In this cathe¬ dral there was a fine library ; but about the year 1560, it was almost totally destroyed. But the capital building is the King’s College, on the south side of the town, which is a large and stately fabric. It is built in form of a square, with cloisters on the south side. The chapel is very ruinous within; but there still remains some wood work of exquisite workmanship. This was preserved by the spirit of the principal at the time of the Reformation, who armed his people, and checked the blind zeal of the barons of the Mearns ; who, after stripping the cathedral of its roof, and robbing it of the bells, were about to violate this seat of learning. The steeple is vaulted with a double cross arch ; above which is an imperial crown, supported by eight stone pillars, and closed with a globe and two gilded crosses. In the year 1631, this steeple was thrown down by a storm, but was soon after rebuilt in a more stately form. This college was founded in 1494, by Wil¬ liam Elphinston, bishop of this place, lord chancellor of Scotland in the reign of James III. and lord privy seal in that of James IV. But James IV. claimed the patronage of it, and it has since been called the Kings College. The library is considerable, but not remarkable for curiosi¬ ties. Hector Boethius was the first principal of the col¬ lege, and was sent for from Paris for that purpose, on an annual salary of forty merks Scots, at thirteen pence each. The square tower on the side of the college was built by contributions from General Monk and the officers under him then quartered at Aberdeen, for the reception of stu¬ dents. The professorships are Divinity, Medicine, Civil Law, Moral Philosophy, Mathematics, Natural Philoso¬ phy, Greek, Humanity, and Oriental Languages; and there are numerous bursaries for the poorer students. Population, by the last return, 1483. ABERDEEN, New, a considerable seaport, and capital of the county of Aberdeen. It is situated on the German Ocean, at the mouth of the river Dee, and in point of popu¬ lation, wealth, and commerce, ranks as the chief town in the north of Scotland. In 1800, an act was obtained for the general improvement of the city ; and since this period its whole appearance and plan have been changed. New and spacious streets have been opened, bridges of commu¬ nication have been built, and other improvements executed, ornamental as well as useful. Union Street, which affords a splendid access from the south and west, extends from the market-place 1350 yards, and is 70 feet wide The houses are built of dressed granite ; and when the street is completely filled up, it will present a fine appearance. To facilitate the access into the town by means of this street, an elegant bridge, of a single arch, the span of which is 132 feet, has been erected at an expense of L.10,000. A new opening to the north has been made by King’s Street; and on the line of this street there is also a bridge over the river Don, of five arches, each of 75 feet, which has been constructed at an expense of L. 14,000. Since 1800, numerous other new streets have been opened, and many of them nearly completed. In consequence of these improvements, Aberdeen may be considered as a spacious, elegant, and well-built city. The public buildings are numerous. There are about 30 places for divine worship. Connected with the established 28 ABE ABE Aberdeen, religion are the East and West churches, forming one continued building 170 feet in length, and adorned with a spire 150 feet in height; besides seven chapels of ease. St Andrew’s church is an elegant new building, construct¬ ed of freestone. There are three episcopal chapels; five meeting-houses for seceders ; eight congregational and baptists ; one methodist meeting-house ; a Roman Catholic chapel, in which there is a good organ ; a quaker meeting¬ house ; two meeting-houses for relief people ; and four for independents. The charitable institutions are numerous. The infir¬ mary is a large and commodious building, for the recep¬ tion and cure of the diseased poor, and has lately receiv¬ ed considerable additions. The managers were incorpo¬ rated by royal charter in 1773. It has extensive funds, derived from donations, bequests, and periodical contri¬ butions. The lunatic asylum was opened in 1800, and is under the same management as the infirmary. A large and elegant building has lately been added to the original house, and ample accommodation is now afforded to all the various classes of lunatics. There is a poor-house for the relief of the indigent, the maintenance and education of destitute children and orphans. Gordon’s hospital, for the maintenance of 90 boys, the sons of decayed bur¬ gesses, is a handsome building, with a good statue of the founder in front. A large addition is about to be made to this institution, in consequence of a magnificent legacy lately received. There are two schools, one for boys and the other for girls, on the Lancasterian plan. There is also another for the education of the deaf and dumb. In addition to these, there are various other schools and seminaries, which are supported by subscriptions, dona¬ tions, and bequests. There are ample funds of the seven incorporated trades for the support of decayed members, widows, and orphans. The college called Marischal College was founded by George Keith, earl marshal, in the year 1593. It has a library containing about 11,000 volumes, an observatory, and an excellent apparatus of philosophical instruments attached to the class of natural philosophy. The languages, mathematics, moral and natural philosophy, natural history, and medicine, are taught here. The other public buildings are the town-house and old tolbooth, which stands on the north side of the market-place, and which is surmounted by a handsome spire 120 feet high; behind which, and con¬ nected with it, has lately been erected the new court-house, which combines the advantages of elegance, convenience, and comfort. In the square, and fronting the town-house, stands the cross. It is adorned with busts cut in stone of the royal family of Scotland, from James I. to James VII. inclusive. The assembly-rooms, in Union Street, were built in 1821, by subscription. They are constructed of beautiful granite, handsomely ornamented. The rooms, which are 90 feet in front, and' 156 feet at the back of the edifice, are splendidly finished in the interior. There are military barracks, which were erected in 1796; a bride¬ well, opened in 1809; and a neat theatre. The commerce and manufactures of Aberdeen are ex¬ tensive and flourishing. One of the most important branches of manufacture is the cotton, which was intro¬ duced about the year 1779, and has given rise to some very great establishments, in some of which steam-en¬ gines are employed. There are other smaller works, which manufacture stripes, winseys, druggets, &c. The whole give employment to about 4000 hands. There are four large woollen manufactories, three of which are moved by water, and the other, being the most extensive, by steam. In these are manufactured superfine broad and narrow cloths, blankets and serges, stockings, worsted yarns, &c. The manufacture of carpeting, chiefly for the Aberdeen London and American markets, has been introduced within these few years. The linen manufacture, parti¬ cularly that of thread, is carried on in all its branches to a great extent. There are several breweries, in which porter and ales are made ; and considerable quantities are annually exported to America and the West Indies. There are also several distilleries, the number of which has been increased since the late reduction of the duty on spirits. Of late years some extensive iron-works have been established, in which are manufactured ships’ an¬ chors, chain-cables, steam-engines, spinning machinery, locks, hinges, &c. The proprietors of these works also built a large steam-vessel of 564 tons burden. There are manufactures of soap, candles, leather, &c. The granite stones," so famous for their durability and strength, which are quarried, dressed, and shipped from this port, form a staple commodity for exportation, and are a great source of wealth to the place, by giving employment to many thousands of industrious labourers. These stones are chiefly used for paving streets; for building bridges, wharfs, and docks; for erecting light-houses, &c. There are six banking establishments in the town. The vessels which belong to the port of Aberdeen amount to 218, carrying 33,572 tons burden. They trade to North and South America, the West Indies, the Medi¬ terranean, the Baltic, Greenland, Davis’ Straits, and most of the ports of the united kingdom. Ship-building is car¬ ried on to a great extent, and gives employment to nu¬ merous hands. The want of any proper harbour was long a detriment to the trade of Aberdeen, and occasion¬ ed the loss of many lives, and of much property. It was narrow at the mouth, and being exposed in easterly storms to the surf from the German Ocean, a bar of sand was raised quite across, on which, at low water, there was not occasionally above three feet of water. To remedy this defect a pier was built in 1776, by Smeaton, on the north side of it, which extended a considerable vray into the German Ocean; and by an act obtained in 1810, it was still farther enlarged. This extensive quay is built of large masses of dressed granite, and measures in length 2300 yards. In consequence of this improvement they have now, a little to the south of the bar, a depth of 17 fathoms at low water, and at the bar from 8 to 9 fathoms, where they had formerly a few feet. The harbour is at present (1829) undergoing some important improve¬ ments, by the construction of wet and dry docks, the extension of the quay, &c. for which purpose a new act was lately obtained from the legislature. Aberdeen is a place of antiquity, its records being pre¬ served from the time of William the Lion, a. d. 1214. From the beginning of the 15th century the journals of the magistrates and town-council came down in a regular series. In the 13th century Aberdeen was a commercial place, and soon grew to be of some note. It suffered oc¬ casionally from the casualties and calamities incident to the almost continued warfare of that rude age. About the beginning of the 14th century an English garrison oc¬ cupied the castle of Aberdeen. But this stronghold was taken by a sudden rising of the citizens, and the English troops were all put to the sword. In 1333 and 1336 the town was burnt by a fleet of Edward III.; it was speedily afterwards rebuilt, and was afterwards known by the name of New Aberdeen. It unites with the burghs of Bervie, Brechin, Montrose, and Arbroath, in sending a representative to parliament. Population by the last re¬ turn in 1821, 43,312, and has since increased by several thousands. Distant 108 miles N. of Edinburgh, 118 from Inverness. Long. 2. 8. W. Lat. 57. 9. N. (f.) A B E Mjrdeen- ABERDEENSHIRE, a county in Scotland, situate in shire, the north-east, between 56. 52. and 57. 42. north latitude, ‘^v^'and between 1. 49. and 3. 48. of longitude west from Greenwich. It is bounded by the German Ocean on the north and east; by the counties of Kincardine, Forfar, and Perth, on the south; and by those of Inverness, Moray, and Banff, on the west. Its greatest length is 85, and breadth 40 miles ; the bounding line being about 280 miles, of which 60 are on the sea-coast. By a careful measure¬ ment of Arrowsmith’s map, it is found to contain 1960 square miles, an area equal to 1,254,400 English or 994,520 Scotch acres; of which somewhat more than one-third is under cultivation. It contains 85 parishes, and is usually described under five divisions. First, Marr, which is a mountainous district, particularly Braemar, the highland part of it; few of the bounding mountains being less than 3000 feet, and several of them more than 4000 feet above the level of the sea. Red deer are here found in great numbers, sometimes 300 in a flock; and moor game abounds in this as in all the more elevated parts of the county. Second, Formartin, of which the land on the sea-coast is low and fertile ; but hills and mosses are spread over the interior. Third, Buchan, the most extensive division next to Marr, having a bold precipitous shore of 50 miles, but generally a flat surface, the soil of which has been greatly improved of late by the cultivation of turnips and clover. The Bullers of Buchan, about 6 miles south from Peterhead, is a natural curiosity, which has been often de¬ scribed by tourists. Fourth, Garioch, a large and beauti¬ ful valley, naturally very fertile. Before the introduction of modern husbandry, it was termed the granary of Aber¬ deen. And, fifth, Strathbogie, the greater part of which consists of hills, mosses, and moors. On a comprehensive review, it may be said, that, with the exception of the low grounds of Buchan, and the highlands of the south-west division, Aberdeenshire consists for the most part of tracks nearly level, but often bleak, naked, and unfertile, though interspersed with many rich spots in a high state of culti¬ vation. In extent, it is very nearly one-sixteenth part of Scotland. Aberdeenshire is not rich in mineral productions. No coal has been found in it, and limestone, though it exists in many parts, is by no means abundant. Slate quarries are wrought to a small extent on the hill of Foudland, in the Garioch division; manganese is found near Aberdeen ; and black lead has been discovered in the neighbourhood of Huntly. The mountains of Braemar contain those precious stones called Cairngorums by the country people, who go thither in whole families to search for them dur¬ ing the summer season ; they are sold, sometimes at high prices, chiefly to the London jewellers. But granite is the most abundant mineral, and has brought considerable sums into the county, besides supplying the inhabitants with excellent stones, for building and other purposes. As many stones have been raised from an acre of land under preparation for tillage, as brought from L.30 to L.50, for paving the streets of London. The exportation of granite to the capital employed at one time about 70 vessels of 7000 tons, and 400 men ; and the value of all the stones exported yearly was stated at L.40,000. The principal rivers are the Dee and the Don. The gross annual produce of the salmon-fisheries on these two rivers was estimated a few years ago at nearly L.35,000. The Ythan and Ugie within the county, and the Deveron and Bogie on its boundaries, are also considerable streams. Muscles are plentiful near the mouth of the Ythan ; and pearl muscles have been sometimes discovered at its lower extremity. One of the jewels of the ancient crown of Scotland, a valuable pearl, is said to have been found here. ABE 29 There are also several lakes well stored with pike, trout, Aberdeen- eels, and other kinds of fish. The county is noted for its shire, chalybeate springs at Peterhead, Fraserburgh, and at Pan- anich on the Dee. The climate of Aberdeenshire, except in the mountain¬ ous districts, is rendered comparatively mild by its being bounded on two sides by the sea. The winters are not so severe as in some of the southern counties, but the springs are late, owing to the prevalence of easterly winds; and in autumn the weather is often wet and stormy. Wheat, however, and all the other crops cultivated in Scotland, come to perfection ; and the inhabitants, who are not sub¬ ject to any local diseases, sometimes live to a great age. The district of Marr, containing almost half the county, abounds in natural woods, which are a source of wealth to their proprietors, and of profitable employment to the in¬ habitants. This country is so well adapted to the growth of trees, that it is only necessary to shut out the cattle by in¬ closures, and the birds and winds supply it with seeds that soon rise into vigorous plants. These woods consist chiefly of Scotch fir ; and the timber, especially what grows in the forests of Braemar, has been thought superior to any that Scotland has imported from the north of Europe. About a tenth part of the whole surface of the county is under wood ; and the trees found in the peat mosses indicate the existence of still more extensive forests in former ages. Ruins of ancient edifices are seen in different parts of the county. In the Garioch district, the vitrified fort called Dun-o-Deer, built on the summit of a beautiful conical hill, which springs about 300 feet from its base, is supposed to be 1000 years old ; and is said to have been the residence of King Gregory the Great (as he is called by the old Scotish historians), who died in 892. The ruins of two buildings, supposed to have belonged to Malcolm Ken- more, who died in 1004, are still pointed out. One of them, situate at Castletown of Braemar, was his hunting seat; the other stands in a small island in Loch Kanders, and must have been inaccessible, except when the lake was frozen. A wooden bridge, which connected it with the land, has been found in the lake. The castle of Kil- drummy, which in 1150 was the property of David Earl of Huntingdon, must have been a princely edifice, cover¬ ing nearly an acre of ground; and its venerable remains still show the power and grandeur of the chieftains by whom it was inhabited. In the same district are some ancient subterraneous retreats, supposed to have been used by the Piets as places of refuge from an invading enemy. The agriculture of Aberdeenshire has been considerably improved of late years; potatoes, turnips, and clover, as well as wheat and other crops, are nowr cultivated accord¬ ing to the best courses of modern husbandry. Farms, how¬ ever, are still generally of a small size, compared with those of the south-eastern counties; and the buildings, though gradually improving, are for the most part much less convenient and comfortable. Here, as in every other part of Scotland, a lease for nineteen years is the most common bond of connection between the landholder and farmer ; but it would appear that the covenants of leases are still in a considerable degree dictated by feudal ideas. In most parts of Aberdeenshire, cattle are a more important object to the tenantry than com ; the number is stated at 110,000; and the sales, to England and to the south of Scotland, amounting to about 12,000, were esti¬ mated some years ago to bring L.150,000 annually. About two-thirds of the population depend entirely on agricul¬ ture ; oatmeal, prepared in different waj^s, with potatoes, is the principal food of the labouring classes. Besides the salmon-fisheries already noticed, the sea- 30 ABE Aberdeen- fishing employs a number of hands. The Greenland shire whale-fishery is carried on with great success, by ships Aber ^ttec*. out from Aberdeen and Peterhead. The whole Venn?' fisheries connected with the county are said to yield from L.80,000 to L.100,000 annually. The old staple manufacture, the knitting of stockings, has declined considerably for several years; but those in wool, cotton, and flax, are upon an extensive scale, and employ a large proportion of the inhabitants. There are also establishments for making sail-cloth, inkle, paper, &c.; and, from the characteristic ingenuity and enterprise of the people, Aberdeenshire may soon assume a still higher rank among the manufacturing counties of Britain. A share of our foreign trade, chiefly with the north of Europe, has been long enjoyed by this county, and the -ecent improvements on the harbour of Aberdeen must contribute essentially to the extension of its commerce. There were, in 1810, belonging to Aberdeen, Peterhead, and Newburgh, 207 vessels, carrying 23,390 tons, and em¬ ploying 1473 men. In 1807 a canal was opened from the harbour of Aberdeen to the town of Inverury, a distance of 18A miles, the expense of which was about L.44,000. The facilities which this canal affords for the conveyance of coal and lime have already proved highly beneficial to the agriculture of the county. The valued rent of the county is L.235,665. 8s. lid. DISTRICTS.

ABERNETFIY, John, an eminent dissenting minister, was the son of Mr John Abernethy, a dissenting minister m Coleraine, and was born there on the 19th of October 1680. When about nine years of age he was separated r°ur 11!LPare.nts’ fiis father being obliged to attend some public affairs m London ; and his mother, to shelter herself rom the mad fury of the Irish rebels, retiring to Derry, a relation who had him under his care, having no oppor¬ tunity of conveying him to her, carried him to Scotland; and thus he escaped the hardships and dangers of the siege of Derry, in which Mrs Abernethy lost all her other children. He afterwards studied at the university of Glasgow where he remained till he took the degree of master m arts; and, in 1708, he was chosen minister of a dissenting congregation at Antrim, in which situation he continued above 20 years. About the time of the Bangorian controversy (for which see Hoadley), a dis¬ sension arose among his brethren in the ministry at Bel¬ fast, on the subject of subscription to the Westminster Confession of haith. In this controversy he became a leader on the negative side, and incurred the censure of Aber¬ nethy.

But his labours were terminated by a sudden attack of the gout in the head, to which he had been subject; and he died in December 1740, in the 60th year of his age. His writings, like his character, are distinguished for candour, liberality, and manly senti¬ ment. He published a volume of sermons on the Divine Attributes; after his death a second volume was pub¬ lished by his friends ; and these were succeeded by four other volumes on different subjects, all of which have been greatly admired. ABERNETHY, a town of Scotland, in Perthshire, si¬ tuated at a short distance to the southward of the right bank of the river Tay, a little above the mouth of the Earne. It is of very ancient date, and is said to have been the seat of the Pictish kings; and there are some uncertain traditions of its existence prior to this period. It is distinguished by a curious piece of antiquity; name¬ ly, a circular tower 74 feet high and 16 in diameter, con¬ sisting of 64 courses of hewn stone. It continued long to be the see of an archbishop, which was afterwards trans¬ ferred to St Andrews. The inhabitants are engaged in the manufacture of linen. The population in 1821 was 1701. 7 miles from Perth. ABERRATION, in Astronomy, a remarkable pheno¬ menon, by which all the stars appear, at certain seasons of the year, to deviate in a slight degree from their true si¬ tuation in the heavens, in consequence, as is now ascer¬ tained, of the motion of the light from every star com¬ bining itself with the motion in the eye of the observer, caused by the earth’s annual revolution round the sun. All vision, it is well known, is performed by the particles or rays of light from any object striking against the eye, and the object invariably appears in that direction in which the rays finally impinge. Hence, for example, arise the effects of refraction, by which the heavenly bo¬ dies appear more elevated in the horizon than they really are; the rays of light, as they penetrate the atmosphere, bending gradually downwards towards the surface of the earth, so as at last to reach the eye of the spectator in a direction more inclined from the horizon than that in which they issue from the object: and thus the latter appears more elevated in the sky than it really is, as in the an¬ nexed sketch. *Slarinits * Star elevated by refraction, truevplace 23*. \ In a similar manner the rays of light which fall directly from the stars, in certain circumstances, owing to the mo¬ tion of the earth, really impinge on the eye of a spectator in a direction somewhat oblique, so that they appear on this account in a situation different from what they really occupy; and this constitutes the aberration. Suppose, for example, the earth is moving in a direction at right angles to that of the light from any star, then it is evident there will be a mutual collision between them; the light will Aberra- not only strike the eye of a spectator, but the eye will tion- also strike the light; the effect will be exactly the same as if the eye had been at rest, and the light had been en¬ dowed with an equal motion in the contrary direction; so that in addition to its direct motion, it has also a slight motion laterally; and the true direction of the impact, therefore, or of the compound motion of the light, ac¬ cording to the well-known laws of the composition of forces, will be the diagonal of the rectangle, the sides of which represent the directions and velocities of the light and of the eye, as in the annexed sketch, where S E represents the direc¬ tion and velocity of the light, F E the direction and velocity of the motion of the earth, and E F, therefore, the direction and velocity of the contrary motion in the light, the earth being supposed at rest. When the light arrives at the eye there¬ fore at E, it has not only the direct motion S E or E G, which is made by construction equal to S E, but also a lateral motion E F; so that the compound motion will be re¬ presented by the diagonal E H, which is the true direction in which the light will really impinge on the eye; so that the star, instead of appearing at S, will appear at s, as far in advance of its true position as the earth has moved in the time the light travels from the star to the eye. To determine the amount of this aberration, therefore, we have only to compare the motion of light with that of the earth in its orbit. Now, from the celebrated discovery of the Danish astronomer Roemer, regarding the successive propagation of light, as found by the observations of the eclipses of Ju¬ piter’s satellites at different seasons of the year, it appears that light actually employs about 15 minutes to travel from the one circumference to the other of the earth’s orbit; and from other still more accurate observations, its velo¬ city has been determined at about 194,000 miles per se¬ cond, while the mean velocity of the earth in her orbit does not exceed 19 miles. Hence it is easy to calculate that the aberration in this case will amount to an angle of about 20" of a degree ; and this case in which the earth’s motion is perpendicular to that of the light is that in which the aberration is the greatest of all; for, as the motion of the earth becomes oblique to that of the light, the aberration gradually diminishes, until at last it disap¬ pears altogether, when the two motions become in one straight line, that is, when the earth is moving either directly from or directly towards the stars. In all cases the apparent direction of the stars will be in the diagonal of the parallelogram, the sides of which represent the direction and the relative motions of the light and of the earth. The aberration of light having been discovered by means of the telescope, this has given rise to a familiar illustration of the subject, which it may be proper to state. It is evident, that before the star can be visible in the telescope, the light in its progress through it must be continually in the axis. Were the telescope, there¬ fore, affected with any considerable lateral motion, this could not take place if the telescope were held directly up to tjie star; because, though the light might enter the telescope in the axis, the lateral motion would quickly with¬ draw the axis from the line of the light, which would strike against the side of the telescope and never reach the eye. If, for example, the light moved successively 32 ABERRATION. I HGF at i, Fig. II G F Aberra- to the points A, B, C, D, E, while the telescope or tube tion. nioved successively parallel to itself into the positions E A, Fyi G g, H h, I i; then A. the light entering at A, by the time it reaches B the tube is off into the position F f and by B the time it could reach E the tube is removed to I i ; so that it is evi¬ dent the star will not be visible at all in the true direction of the light. In order that this may always remain in the telescope, and traverse it from end to end, this must be set in the posi- • E tion E i, oblique to E A; then the light entering 2. will advance to b in the same time that the axis of the tube advances parallel to itself to F f; so that the light will still remain in the axis. In the same manner the light and the tube will continue to advance by pro* portional steps till the former reaches the eye, where the star will appear in the direction of the tube, and that as formerly in the diagonal of the parallelogram formed by the directions and velocities of the two motions. An¬ other illustration was suggested by Clairaut in the Memoires de 1’Academic des Sciences for the year 1746, by supposing drops of rain to fall rapidly and quickly after each other from a cloud, under which a person moves with a very narrow tube; in which case, it is evident that the tube must have a certain inclination, in order that a drop which enters at the top may fall freely through the axis of the tube, without touching the sides of it; which inclination must be more or less, according to the velocity of the drops in respect to that of the tube: then the angle made by the direction of the tube and of the falling drops is the aberration arising from the combination of those two motions. In all cases it will be observed the aberration takes place in the direction of the earth’s motion. Hence it is easy to deduce, from what we have stated, the effects on the different stars. Consider, for example, those situated in the pole of the ecliptic. To the rays of light from these, the earth’s motion will always be at right angles; the aberration on them, therefore, will always be of the same amount, viz. about 20"; but as the earth changes the direction of its motion along the ecliptic, the aberration will change its di¬ rection also, so that the star will appear to move in a little orbit, similar to, and parallel with the ecliptic; the apparent situation of the star revolving annually round the true place, as the earth revolves round the sun. Con¬ sider again the stars situated in the plane of the ecliptic. To the rays of light from these, the earth's motion will be at one time at right angles, as at A and B in the annexed sketch, and at another in the same direction, as at C and D; for in all these cases we may hold the dimensions of the earth’s orbit as nothing compared with the distance of the star. At A, 7> s therefore, the earth being supposed to move in the di¬ rection A D B, so as to make the star appear at a, the aberration will be 20" in the direction Sa, and at B 20" in'’ the direction S b, so as to make the star appear at b, while at C and D it will be nothing, and the star will appear in its true place at S. The apparent situation will, therefore, appear annually to oscillate on each side of the true, to the extent of 20". Between the two extremes therefore, namely, the pole of the ecliptic, where the aberration causes the star to revolve in a circle, and the plane of the ecliptic, where it causes it to oscillate in a straight line, the stars will all describe elliptic curves, elongated 40" in a direction parallel to the plane of the ecliptic, and the breadth or lesser axis diminishing continually from the pole towards the plane of the ecliptic, where the curve passes into a straight line. These motions in the stars are confirmed by the observations of astronomers, (see Astronomy,) and they furnish one among many other beautiful examples of that remarkable and perfect accordance which in this science subsists everywhere be¬ tween theory and fact. The effects of aberration also present a striking, and one of the few direct proofs which astronomy furnishes of the motion of the earth, these being quite unaccountable on any other hypo¬ thesis. Such are the principal phenomena of aberration. This great discovery, one of the finest in modern astronomy, we owe to the accuracy and ingenuity of the distinguish¬ ed astronomer Dr Bradley, who was led to it in the year 1727, by the result of some observations which he made, with a view of determining the annual parallax of the fixed stars. See Parallax. The annual motion of the earth about the sun had been much doubted and warmly contested. The defenders of that motion, among other proofs of the reality of it, con¬ ceived the idea of adducing an incontestible one from the annual parallax of the fixed stars, if the stars should be within such a distance, or if instruments and observations could be made with such accuracy, as to render that pa¬ rallax sensible. And with this view various attempts have been made. Before the observations of M. Picard, made in 1672, it was the general opinion that the stars did not change their position during the course of a year. Tycho Brahe and Ilicciolus fancied that they had assured them¬ selves of it from their observations ; and from thence they concluded that the earth did not move round the sun, and that there was no annual parallax in the fixed stars. M. Picard, in the account of his Voyage d Uranibourg, made in 1672, says that the pole star, at different times of the year, has certain variations, which he had observed for about 10 years, and which amounted to about 40" a year : from whence some, who favoured the annual motion of the earth, were led to conclude that these variations were the effect of the parallax of the earth’s orbit. But it was im¬ possible to explain it by that parallax, because this mo¬ tion was in a manner contrary to what ought to follow only from the motion of the earth in her orbit. In 1674 Dr Hooke published an account of observations which he said he had made in 1669, and by which he had found that the star y Draconis was 23" more northerly in July than in October; observations which, for the pre¬ sent, seemed to favour the opinion of the earth’s motion, although it be now known that there could not be any truth or accuracy in them. Ilamsteed having observed the pole star with his mural quadrant, in 1680 and the following years, found that its declination was 40" less in July than in December; which observations, although very just, were yet, however, im¬ proper for proving the annual parallax; and he recom- Aberra tion.

(liug, to be firmly fixed on a strong foundation, for decid- ing a doubt which was otherwise not soon likely to be brought to a conclusion. In this state of uncertainty and doubt, then, Dr Brad¬ ley, in conjunction with Mr Samuel Molineux, in the year 1725, formed the project of verifying, by a series of new observations, those which Dr Hook had communicated to the public almost 50 years before. And as it was his at¬ tempt that chiefly gave rise to this, so it was his method in making the observations, in some measure, that they followed; for they made choice of the same star, and their instrument was constructed upon nearly the same principles: but had it not greatly exceeded the former in exactness, they might still have continued in great uncer¬ tainty as to the parallax of the fixed stars. For this, and many other convenient and useful astronomical instru¬ ments, philosophers are indebted to the ingenuity and ac¬ curacy of Mr Graham. The success of the experiment evidently depending so much on the accuracy of the instrument, this became a leading object of consideration. Mr Molineux’s appara¬ tus then having been completed, and fitted for observing, about the end of November 1725, on the third day of December following, the bright star in the head of Draco, marked y by Bayer, was for the first time observed, as it passed near the zenith, and its situation carefully taken with the instrument. The like observations were made on the fifth, eleventh, and twelfth days of the same month ; and there appearing no material difference in the place of the star, a further repetition of them, at that sea¬ son, seemed needless, it being a time of the year in which no sensible alteration of parallax, in this star, could soon be expected. It was therefore curiosity that chiefly urged Dr Bradley, who was then at Kew, where the in¬ strument was fixed, to prepare for observing the star again on the 17th of the same month; when,-having ad¬ justed the instrument as usual, he perceived that it passed a little more southerly this day than it had done before. Not suspecting any other cause of this appearance, it was ascribed to the uncertainty of the observations, and that either this or the foregoing was not so exact as had been supposed. For which reason they proposed to re¬ peat the observation again, to determine from what cause this difference might proceed: and upon doing it, on the 20th of December, the doctor found that the star passed still more southerly than at the preceding observation. This sensible alteration surprised them the more, as it was the contrary way from what it would have been had it proceeded from an annual parallax of the star. But being now pretty well satisfied that it could not be en¬ tirely owing to the want of accuracy in the observations, and having no notion of any thing else that could cause such an apparent motion as this in the star, they began to suspect that some change in the materials or fabric of the instrument itself might have occasioned it. Under these uncertainties they remained for some time ; but being at length fully convinced, by several trials, of the great exactness of the instrument, and finding, by the gradual increase of the star’s distance from the pole, that there must be some regular cause that produced it, they took care to examine very nicely, at the time of each ob¬ servation, how much the variation was ; till about the be¬ ginning of March 1726, the star was found to be 20" more southerly than at the time of the first observation : it now indeed seemed to have arrived at its utmost limit south¬ ward, as in several trials, made about this time, no sen¬ sible difference was observed in its situation. By the middle of April it appeared to be returning back again VOL. II. A T I O N. 33 towards the north ; and about the beginning of June it Aberra- passed at the same distance from the zenith as it had tion. done in December, when it was first observed. From the quick alteration in the declination of the star at this time, increasing about one second in three days, it was conjectured that it would now proceed northward, as it had before gone southward, of its present situation; and it happened accordingly; for the star continued to move northward till September following, when it again became stationary; being then near 20" more northerly than in June, and upwards of 39" more northerly than it had been in March. From September the star again re¬ turned towards the south, till, in December, it arrived at the same situation in which it had been observed twelve months before, allowing for the difference of declination on account of the precession of the equinox. This was a sufficient proof that the instrument had not been the cause of this apparent motion of the star; and yet it seemed difficult to devise one that should be ade¬ quate to such an unusual effect. A nutation of the earth’s axis was one of the first things that offered itself on this occasion; but it was soon found to be insufficient; for though it might have accounted for the change of declina¬ tion in y Draconis, yet it would not at the same time accord with the phenomena observed in the other stars, particu¬ larly in a small one almost opposite in right ascension to y Draconis, and at about the same distance from the north pole of the equator: for though this star seemed to move the same way as a nutation of the earth’s axis would have made it, yet changing its declination but about half as much as y Draconis in the same time, as appeared on comparing the observations of both made on the same-days, at different seasons of the year, this plainly proved that the apparent motion of the star was not occasioned by a real nutation; for had this been the case, the alteration in both stars would have been nearly equal. The great regularity of the observations left no room to doubt, but that there was some uniform cause by which this unexpected motion was produced, and which did not depend on the uncertainty or variety of the seasons of the year. Upon comparing the observations with each other, it was discovered that, in both the stars above mentioned, the apparent difference of declination from the maxima was always nearly proportional to the versed sine of the sun’s distance from the equinoctial points. This was an inducement to think that the cause, whatever it was, had some relation to the sun’s situation with respect to those points. But not being able to frame any hypothesis suf¬ ficient to account for all the phenomena, and being very desirous to search a little further into this matter, Dr Bradley began to think of erecting an instrument for him¬ self at Wanstead; that, having it always at hand, he might with the more ease and certainty inquire into the laws of this new motion. The consideration likewise of being able, by another instrument, to conform the truth of the observations hitherto made with that of Mr Moli¬ neux, was no small inducement to the undertaking; but the chief of all was, the opportunity he should thereby have of trying in what manner other stars should be af¬ fected by the same cause, whatever it might be. For Mr Molineux’s instrument being originally designed for observing y Draconis, to try whether it had any sensible parallax, it was so contrived as to be capable of but little alteration in its direction; not above seven or eight mi¬ nutes of a degree : and there being but few stars within half that distance from the zenith of Kew bright enough to be well observed, he could not, with his instrument, thoroughly examine how this cause affected stars that E 34 ABERRATION.

Pursuing this happy idea, he calculated the observing, before he perceived that the notion they had aberration from the relative velocities of the earth and of before entertained, that the stars were farthest north and light, and comparing it with his own observations, was south when the sun was near the equinoxes, was ofily delighted to find them agree in every particular; so that true of those stars which are near the solstitial colure, no doubt could remain of the truth of his discovery.

When the in the morning. planet is stationary, the aberration disappears altogether, Though he afterwards discovered that the maxima, in because the light itself, participating of the motion of the most of these stars, do not happen exactly when they planet, strikes the earth not only with its usual direct pass at those hours; yet, not being able at that time to motion, but also with a lateral motion exactly the s&me prove the contrary, and supposing that they did, he en- as that of the earth itself.

It is the same as if inclination equally. It has been before noticed, that it both the earth and the planet were at rest, and therefore appeared from Mr Molineux’s observations, that y Bra- there cannot be any aberration. In every other case, the conis changed its declination above twice as much as the aberration is determined by combining the motion of light before-mentioned small star that was nearly opposite to not only with the earth’s, but with the planet’s motion it; but examining the matter more nicely, he found that also; and doing this it is found, that in every case the the greatest change in the declination of these stars was aberration is equal to the motion of the planet about the as the sine of the latitude of each star respectively. This earth or its geocentric motion, during the interval that ABE ^.berra- light employs in passing from the planet to the earth. tion. Thus, in the sun, the aberration in longitude is constant- *~v~**J ly 20", that being the space moved by the sun, or, what is the same thing, by the earth, in 8' 7", the time in which light passes from the sun to the earth. In like manner, knowing the distance of any planet from the earth, by proportion it will be, as the distance of the sun is to the distance of the planet, so is 8' 7" to the time of light passing from the planet to the earth: then computing the planet’s geocentric motion in this time, that will be the aberration of the planet, whether it be in longitude, lati¬ tude, right ascension, or declination. Since the motion of the planets affects so much the aberration, ought not the motion of the fixed stars rela¬ tively to our system, if they have any, as some have sus¬ pected, be rendered sensible in this- manner ? Their pro¬ digious distance has hitherto rendered these motions, if they do exist, almost insensible. But this would not affect the motion of light. This element flies through the re¬ motest parts of the system; and if it be really material, the motion with which it is propelled from one point must con¬ tinue for ever afterwards to affect it, unless opposed or modified by extraneous influence. If the stars, therefore, have any motion laterally in respect of the earth, so will the light which issues from them, and which, preserving undiminished its original impulse, must strike the eye of a spectator on the earth not only with a direct motion, but also with one to the right or left similar to that of the star; and this ought to affect the aberration just in the same manner as if the star were no farther off than any of the planets. The same thing would be observed if the earth, along with the whole solar system, as the late Dr Herschel and other astronomers have attempted to prove, be advancing forward among the stars. Since, however, no such effect has ever been noticed, it would seem to follow, that the stars, as well as the sun, are really at rest; or if they have any motion, it is but a slow one, even compared with that of the earth or the planets round the sun. This is certainly a curious speculation, which we have never seen discussed by astronomers. See Astro¬ nomy. (c.) Aberration, in Optics, a certain deviation in the rays of light, from the true or geometrical focus of re¬ flection or refraction in curved specula or lenses, arising from two causes, viz. Is#, the figure of the speculum or lens, giving rise to what is called the spherical aberration ; and, 2d, the unequal refrangibility of the rays of light giving rise, in lenses only however, to a far more mate¬ rial, and in other respects inconvenient aberration, term¬ ed the chromatic, or the aberration of colour, or of refran- gibility. The object of all specula or lenses, is to collect the rays of light proceeding from any object into a single point, so as to form there a distinct image of the object, either enlarged or diminished, according as our purposes may require: and on this principle depends the whole operation of the telescope, the microscope, and other opti¬ cal instruments. The more completely the rays can be collected into a focus, so much the more distinctly, in every case, does the image of the object appear at that point, and so much the more perfect is the operation of the instrument. But there are certain curves or figures in the speculum or lens, which are necessary to produce this effect. Parallel rays, for example, can only be collected into one focus by a reflecting speculum of a parabolic form, or by a refracting lens of parabolic or hyperbolic, combined with spherical curves: all other forms cause more or less a dispersion or aberration of the rays from the focus. In practice, however, it is extremely difficult to form the lenses into these complex curves; and as the ABE 35 spherical form is much more easily constructed, and as the Aberra- aberration from it is not generally attended with serious tion inconvenience, this form has been universally adopted. II The amount of the aberration is measured either by the. Atex‘ distance longitudinally at which the rays meet from the true focus, or by the distance laterally by which they are dispersed from it. In all double convex lenses of equal spheres, the longitudinal aberration of the ex¬ treme ray is If of the thickness of the lens. The small¬ est aberration takes place when the radii of the spheres are as 1 to 6, the more convex surface being exposed to the rays; in that case, it is only ly^th of the thickness of the lens. See Optics. The aberration of refrangibility is of far more import¬ ance. It arises from this circumstance, that in a homo¬ geneous lens of glass the violet rays are greatly more refracted than the red. The latter are therefore thrown to a greater distance, and the others in proportion almost all deviating from the true focus: hence arises that con¬ fusion of images, and that fringe of extraneous colour with which objects are surrounded when seen through glasses of this description, which has ever formed the great obstacle to the perfection of the refracting telescope; so much so, that Sir Isaac Newton, misled at the time by a partial view of the subject, and others after him, were led to de¬ spair of success in correcting this defect, and thus direct¬ ed their chief attention to those of the reflecting kind. Subsequent discoveries, however, led to the invention of achromatic glasses, by which the refracting telescope has been wonderfully improved ; and some important experi¬ ments, we understand, are now going on at the Royal In¬ stitution in London, by M. Faraday, under the direction of the Board of Longitude, in the manufacture of a more perfect glass than has hitherto been used, from which we may hope to see these instruments carried to a yet higher degree of perfection.

Abi¬ melech afterwards gave considerable presents to Abra¬ ham ; and a covenant, that of Beersheba, was entered in¬ to between them, a. m. 2107. After the death of Abra¬ ham, there being a famine in the neighbouring countries, Isaac his son also withdrew into Gerar, which was then likewise governed by a king called Abimelech, probably the successor of the former. Here Rebekah’s beauty forced her husband to employ Abraham’s artifice. Abimelech, discovering that they were nearly related, chid Isaac for calling his wife his sister; and at the same time forbade all his subjects, upon pain of death, to do the least injury to Isaac or Rebekah. Isaac’s prosperity lost him the king’s friendship, and he was desired to go from among them. He obeyed; but Abimelech afterwards entered into a covenant with him, a. m. 2200.

ABINGDON, a market-town in Berkshire, situated on a branch of the Thames, derives its name from an an¬ cient abbey. The streets, which are well paved, termi¬ nate in a spacious area, in which the market is held; and in the centre of this area is the market-house, which is supported on lofty pillars, with a large hall of freestone above, in which the summer assizes for the county are held, and other public business done, the Lent assizes being held at Reading. It has two churches; one dedi¬ cated to St Nicholas, and the other to St Helena: the latter is adorned with a spire, and both are said to have been erected by the abbots of Abingdon. Here are also two hospitals, one for six, and the other for thirteen poor men, and as many poor women; a free school; and a cha¬ rity school. The town was incorporated by Queen Mary. It sends two members to parliament, who are chosen by the inhabitants at large not receiving alms. Its great manufactures are sail-cloth, sacking, and especially malt, large quantities of which are sent by water to London. It is seven miles south of Oxford, 47 east of Gloucester, and 55 west of London. This town is supposed by Bishop Gibson to be the place called in the Saxon annals, Clove- s/too. Long. 1. 12. W.

ABINTESTATE, in Law, is applied to a person who inherits the right of one who died intestate, or without making a will. ABIPONIANS, a tribe of American Indians, who formerly inhabited the district of Chahs in Paraguay; but the hostilities of the Spaniards have now obliged them to remove southward into the territory lying between Santa he and St Jago. M. Dobrizhoffer, who lived seven years in their country, informs us, in his account of them pub¬ lished in 1785, that , they are not numerous, the whole nation not much exceeding 5000; for which he assigns as a reason an unnatural custom among their women of sometimes destroying their own children, from mptives of jealousy lest their husbands should take other mates during the long time they give suck, which is not A B L 37 less than two years. They are naturally white, but, by Abipo- exposure to the air and smoke, become of a brown colour, nians They are a strong and hardy race of people, which our II author attributes to their marrying so late, an Abiponian ^hjacta- seldom or never thinking of marriage till 30 years of age. / They are greatly celebrated on account of their chastity and other virtues; though, according to our author, they have no knowledge of a Deity. They make frequent in¬ cursions into the territories of the Spaniards, mounted on the horses which run wild in those parts. They have a kind of order of chivalry for their warriors; and are so formidable, that 100 of their enemies will fly before ten of these horsemen. The hatred which these savages, whose manners, though rude and uncultivated, are in many respects pure and virtuous, bear to the Spaniards, is invincible. “ These pretended Christians,” says our author, “ who are the scum of the Spanish nation, prac¬ tise every kind of fraud and villany among these poor barbarians; and their corrupt and vicious morals are so adapted to prejudice the Abiponians against the Christian religion, that the Jesuit missionaries have, by a severe law, prohibited any Spaniard from coming, without a for¬ mal permission, into any of their colonies.” From his account of the success of the Jesuits in converting them to Christianity, however, it does not appear that they have been able to do more than bribe them to a compli¬ ance with the ceremonies of the Popish superstition; so that in general they are quite ignorant and uncivilized; a most striking instance of which is, that in counting they can go no further than three; and all the art of the Je¬ suits to teach them the simplest use and expression of numbers has proved unsuccessful. Dobrizhoffer’s account of this people was translated into English by Mr Southey, and published in 1822, in 3 vols. 8vo. ABIRAM, a seditious Levite, who, in concert with Ko- rah and Dathan, rebelled against Moses and Aaron, in order to share with them in the government of the people; when Moses ordering them to come with their censers before the altar of the Lord, the earth suddenly opened under their feet, and swallowed up them and their tents; and at the same instant fire came from heaven and consumed 250 of their followers.

ABJURATION, in our ancient customs, implied an oath taken by a person guilty of felony, and who had fled to a place of sanctuary, whereby he solemnly engaged to leave the kingdom for ever.

II ABLANCOURT. See Perrot. ABLANQUEJO, a river of Spain, in the province of Soria, which falls into the Tagus. ABLATIVE, in Grammar, the sixth case of Latin nouns. The word is formed from auferre, “ to take away.” Priscian also calls it the comparative case; as serving among the Latins for comparing, as well as taking away. The ablative is opposite to the dative; the first ex¬ pressing the action of taking away, and the latter that of giving. In English, French, &c. there is no precise mark where¬ by to distinguish the ablative from other cases; and we only use the term from analogy to the Latin. Thus, in the two phrases, the magnitude of the city, and he spoke much of the city ; we say, that of the city in the first is ge¬ nitive, and in the latter ablative; because it would be so if the two phrases were expressed in Latin. The question concerning the Greek ablative has been the subject of a famous literary war between two great grammarians, Frischlin and Crusius; the former maintain¬ ing, and the latter opposing, the reality of it. The dis¬ pute still subsists among their respective followers. The chief reason alleged by the former is, that the Roman writers often joined Greek words with the Latin pre¬ positions which govern ablative cases, as well as with nouns of the same case. To which their opponents answer, that the Latins anciently had no ablative themselves, but in¬ stead thereof made use, like the Greeks, of the dative case ; till at length they formed an ablative, governed by prepositions, which were not put before the dative : that, at first, the two cases had always the same termination, as they still have in many instances; but that this was afterwards changed in certain words. It is no wonder, then, that the Latins sometimes join prepositions which govern an ablative case, or nouns in the ablative case, with Greek datives, since they were originally the same; and that the Greek dative has the same effect as the La¬ tin ablative. Ablative Absolute, in Grammar, is a phrase detach¬ ed or independent of the other parts of a sentence or dis¬ course. In the Latin language it is frequent, and it has been adopted by the moderns. ABLAY, a country of Great Tartary, governed by a Calmuck chief, but subject to Russia, to obtain its pro¬ tection. It lies east of the river Irtisch, and extends 500 leagues along the southern frontiers of Siberia. ABLE, or Abel, Thomas, chaplain to Queen Cathe¬ rine, consort to Henry VIII. distinguished himself by his zeal in opposing the proceedings against that unfortunate princess for a divorce. For this purpose he wrote a piece entitled Tractatus de non dissolvendo Henrici et Catharince matrimonio. But the title of the book, according to Bishop Tanner, was Invicta Veritas. He took the degree of bachelor of arts at Oxford on the 4th of July 1513, and that of master of arts on the 27th July 1516. In 1534 he fell under a prosecution for1 being concerned in the af¬ fair of Elizabeth Barton, called the Holy Maid of Kent. This was an infamous impostor, suborned by the monks to use strange gesticulations, exhibit fictitious miracles, and to feign the gift of prophecy ; and so well did she act her part, that she drew some persons of respectability to her interest: but being detected, she was condemned and executed, after discovering the names of her princi¬ pal accomplices and instigators. On her account Able was charged with misprision of treason; and being also one of those who denied the king’s supremacy over the church, he was apprehended and imprisoned. He was ABO afterwards hanged, drawn, and quartered, at Smithfield, in Ablecti 1540. || ABLECTI, in Roman antiquity, a select body of sol- diers chosen from among those called Extraordinarii. ABLEGMINA, in Roman antiquity, those choice parts of the entrails of victims which were offered in sacrifice to the gods.

Ablutions ap¬ pear to be as old as any ceremonies, and external worship itself. Moses enjoined them, the heathens adopted them, and Mahomet and his followers have continued them; thus they have got footing among most nations, and make a considerable part of many established religions. ABNER, the son of Ner, father-in-law to Saul, and general of all his forces, served him on all occasions with fidelity and courage. After the death of that prince, Abner set Ishbosheth, Saul’s son, on the throne. A war breaking out between the tribe of Judah, who had elected David king, and Israel, Abner marched against that prince with the flower of his troops, but was defeated. Abner afterward, being disgusted, went over to David, and in¬ duced the chiefs of the army and the elders of Israel to declare for him. He was received by David with every mark of affection, which gave offence to Joab, by whom he was insidiously put to death, a. m. 2956. ABNOBA, now Abenow, in Geography, a long range of mountains in Germany, extending from the Rhine to the Necker, and having different names according to the different countries through which they stretch. About the river Maine they are called the Oden or Otenwald; between Hesse and Franconia, the Spessart; and about the duchy of Wirtemberg, where the Danube takes its rise, they receive the name of Baar. ABO, a circle in the province of Finland, recently transferred to Russia from Sweden. By the new division, it extends over 12,145 square miles, between Lat. 59. 50. and 62. 20. N. and Long. 19. 10. and 23. 46. E. It is bounded on the north by the circle of Wasa; on the east by Helsingfors; on the south by the Gulf of Finland; on the south-east by the Baltic Sea; and on the west by the Gulf of Bothnia, in which the Aland group of islands comprehended in this circle are situated. It contains 6 cities, and 4980 hamlets. The inhabitants, at the census of 1805, were 207,960; of wdiom 18,591 lived in the citiefe, and the remainder in the country places. On the sea- coast, and on the eastern side of the circle, it is rather hilly; but the centre is chiefly a level country. The land is of medium fertility, producing rye, potatoes, hemp, flax, hops, and tobacco. The forests produce plants, pitch, and tar, and some potash. The coasts yield abundance of fish. It is divided into 9 horads or baronies. ABO, a city, the capital of the late Swedish, but now Russian, province of Finland. The river Aurajchi divides it into two parts. By a most extensive fire in November 1827, nearly the whole city was destroyed, with the public buildings, including the university, and its valuable library. Before this calamity, Abo contained 1100 houses and 11,300 inhabitants, was the see of a bishop, and the chief ABO ABO 39 Aboard trading port of Finland.

Hence any person who enters a ship is said to go aboard: but when an enemy enters in the time of battle, he is said to board; a phrase which always implies hostility To fall aboard of is to strike or encounter another ship when one or both are in motion, or to be driven upon a ship by the force of the wind or current.—Aboard-main-tacJi, the order to draw the main-tack, i. e. the lower corner of the main-sail, down to the Chess-tree. ABOCRO, or Aborrel, in Geography, a town near the river Ankobar or Cobre, on the African Gold Coast. It gives name to a republican province. ABOD, a market town of Hungary, in the circle of hither Theiss, and the district of Erlau, where woollen manufactories are established. ABOLA, in Geography, a division of the Agow, in Abyssinia, is a narrow valley, through which runs a river of the same name, whose waters receive many tributary streams from the lofty, rugged, and woody mountains that form the valley. ABOLI1ION, in the Roman law, is the annulling a prosecution, or legal accusation: and in this sense it is different from amnesty; for, in the former, the accusation might be renewed by the same prosecutor, but in the latter it was extinguished for ever. Within 30 days after a public abolition, the same accuser, with the prince’s licence, was allowed to renew the charge ; after a private abolition, another accuser might renew it, but the same could not. Abolition was also used for expunging a per¬ son s name from the public list of the accused, hung up in the treasury. It was either public, as that under Au¬ gustus, when all the names which had long hung up were expunged at once; or private, when it was done at the motion of one of the parties. ABOLLA, in antiquity, a wrarm kind of garment, lined or doubled, worn by the Greeks and Romans, chiefly out of the city, in following the camp. Critics and antiquaries are greatly divided as to the form, use, kinds, &c. of this garment. . Papias makes it a species of the toga, or gown; but Nonnius, and most others, suppose it to be a species of the pallium, or cloak. The abolla seems rather to have stood opposed to the toga, which was a garment of peace, as the abolla was of war ; at least Varro and Martial place *n °PPosite light. There seem to have been different kinds of abollee, appropriated to different charac- ters and occasions. Even kings appear to have used the abolla.- Caligula was offended with King Ptolemy for appearing at the shows in a purple abolla, the splendour oi which drew the eyes of the spectators from the empe¬ ror to himself. 1 ABON, Abona, or Abonis, in Ancient Geography, a town and river of Albion. The town, according to Cam¬ den, is Abingdon ; and the river, Abhon or Avon. Others take the town to be Porshut, at the mouth of the river Avon, near Bristol. Abuin or Avon, in the Celtic lan¬ guage, denotes a river. ABORAS, in Ancient Geography, by Xenophon called Araxes, a river of Mesopotamia, which flows into the Euphrates at Circesium. In the negotiation between JJioelesian and Narses, near the end of the third century, i was hxed as the boundary between the Roman and Persian empires. . ABORIGINES, in History, originally a proper name, Abori- given to a certain people in Italy, who inhabited the an- gines cient Latium, or country now called Campagna di Roma. II Whence this people came by the appellation is much dis- Abortlon- puted. St Jerome says, they were so called, as being absque origine, the primitive planters of the country after the flood: Dionysius of Halicarnassus accounts for the name, as denoting them the founders of the race of inha¬ bitants of that country: others think them so called as being originally Arcadians, who claimed to be earth-born, and not descended from any people. The term Abori¬ gines, in modern geography, is applied to the primitive in¬ habitants of a country, in contradistinction to colonies, or new races of people. ABORTION, in Midwifery, the premature exclusion of a foetus. It has sometimes been doubted whether this unnatural practice was ranked as a crime in the laws of Greece and Rome. This question has been revived, and elaborately discussed in France, by some members of the Institute. The subject, it seems, had been incidentally alluded to in a discourse of Gregoire’s upon the influence of Christianity on the condition of the female sex, read in the early part of 1814. This produced two dissertations, one by M. Clavier, and the other by M. Boissonade; the first maintaining the impunity of the practice among the ancients, the last, that it was on the contrary viewed as a penal offence. We find, says M. Clavier, that in one of Plato’s dia¬ logues (Theat.) Socrates is made to speak of artificial abortion, as a practice not only common, but allowable; and Plato himself authorizes it in his Republic, (lib. v.) Aristotle {Polit. lib. vii. c. 17) gives it as his opinion, that no child ought to be suffered to come into the world, the mother being above forty, or the father above fifty-five years of age. Lysias maintained, in one of his pleadings quoted by Harpocration, that forced abortion could not be considered homicide, because a child in utero was not an animal, or separate existence. M. Clavier admits, that, in a treatise ascribed to Galen, (An animal sit quod in utero est ?) there is mention made of enactments by Solon and Lycurgus against this crime; but he maintains that this is a spurious production, and that, at any rate, his testimony cannot be opposed to that of so many writers who lived long before his age. Among the Romans, Ovid (Amor. lib. ii.), Juvenal (Sat. vi. v. 594), and Seneca (Consol, ad Helv. 16), though they lament in strong terms the frequency of this enormity, yet they never al¬ lude to any laws by which it might be suppressed. Vari¬ ous other writers, it is said, preserve the same silence on this point, whilst joining in general reprobation of the crime. On the other hand, M. Boissonade appeals not only to the authority of Galen, but of Cicero, (Pro Cluentio,) as placing it beyond a doubt, that, so far from being allowed to pass with impunity, the offence in question was some¬ times punished with death. WTith regard to the autho¬ rity of Lysias, he states, that the pleading referred to is quoted by Harpocration himself as of dubious authenti¬ city ; and, as to Plato and Aristotle, he observes, that their speculative reasonings, in matters of legislation, ought not to be confounded with the actual state of the laws. And he adds, that Stobseus (Serm. 73) has preserved a pass¬ age from Musonius, in which that philosopher expressly states, that the ancient lawgivers inflicted punishments on females who caused themselves to abort. It seems indeed difficult to believe, that the practice in question should have been allowed to prevail without being denounced as criminal by the lawgivers of Greece and Rome; but it is not so clear that there was any law which 40 ABO ABO Abortion punished it with death. Thnse readers who have any II curiosity to enter more deeply into the inquiry, will be Aboulfeda. enabled to do so by consulting the various authorities to which M. Clavier and M. Boissonade have appealed, in support of their respective views of the question. The notorious frequency of the practice forms an odious feature in the manners of ancient times. Seneca makes it a ground of distinction for Helvia, that she had never, like others of her countrywomen, destroyed the child in her womb, in order to preserve her shape. « By the law of England till lately, the only party held to be guilty of murder in forcingabortion was the woman, when she was proved to have taken means to destroy a child quick in the womb, and actually to have thereby destroyed it. But in 1803, an act was passed, inflicting the punishment of death upon all concerned in administering any noxious substance with the intent to procure the miscarriage of any woman quick with child. The procuring or attempt¬ ing it before the child has quickened, is punishable only with imprisonment or transportation. This law is evident¬ ly grounded upon a false hypothesis, that the foetus is not quick or alive till its motion in the womb becomes per¬ ceptible to the mother; and, what is of more importance, it makes no provision against the attempt to procure abor¬ tion by manual application. The reader will find a curi¬ ous illustration of this defect, in a trial which occurred at the assizes held at Bury St Edmunds in 1808. See Trial of William Pizzy, &c. Ipswich, 1808. The case of John Fenton, tried at Perth in 1763, was the first instance of a criminal prosecution for this offence in Scotland; and here the public prosecutor restricted the libel to an arbitrary punishment. Our writers indeed agree, that, by the law of Scotland, the forcing of abortion is not homicide, whether the child be quick or not, ex¬ cept where the mother is killed in the process. Imprison¬ ment or transportation may, and is all that can, in any case, be inflicted. Abortive Vellum, is made of the skin of an abortive or immature calf. ABOUKIR, a small town of Egypt, with a castle and a little island adjoining, with which it is connected by a chain of rocks. It stands at the eastern extremity of the long neck of land between the sea and the lakes Mareotis and Maadie, upon which Alexandria, about twelve miles to the westward, is also situated. Eastward lies the spa¬ cious bay of Aboukir, reaching to the mouth of the Nile. This vicinity was the scene of some of the greatest events which distinguished the late war between Britain and France. In the bay of Aboukir, Nelson found the French fleet which had conveyed Buonaparte to Egypt, and in¬ stantly penetrating its line, gained that signal victory usually called the “ Battle of the Nile,” in which the whole of the enemy’s fleet, with the exception of two vessels, were destroyed or captured. It was at Aboukir also that Sir Ralph Abercromby, in 1801, effected his landing, and having driven the enemy up the sand hills, took possession of the place. In other respects Aboukir is not of much importance. ABOULFEDA, or Abulfeda, the most celebrated of the Arabian writers on history and geography. Among his contemporaries he was also distinguished both as a ruler and a warrior. His descent was in a direct line from Ayoub, father to Saladin, and from whom the house of that conqueror received the appellation of Ayoubites. Omar, the grandson of Ayoub, was one of Saladin’s most distmguished generals, and enjoyed the privilege, which he transmitted to his posterity, of being placed always on the right of the army. In reward of his services, he was created Prince of Hamah, the ancient Apamea, which, with some territories adjoining, became hereditary in his Aboulfeda family. They were transmitted, in the course of succes- sion, to Mahommed Mahmoud, and to Mahommed, the uncle of Aboulfeda. Although none of these princes equalled the military glory of Omar, they were yet distinguished both in arms and letters. Continually engaged in military expeditions, their court was at the same time open to learned men. It is mentioned, among the proofs of their zeal for science, that Mahmoud caused to be constructed at Hamah, a gilded sphere of great magnitude, on which all the stars then known were represented. Aboulfeda was son to Ally, the brother of Mahommed. He was born at Damascus in the year 672 of the Hegira, (1273 a. d.) His early years were spent in the study of the Koran and of the sciences. By the age of twelve, however, he was summoned to the field, and was present at the attack of Marcab, a castle belonging to the knights of St John. Syria was then shaken by continual war, and thus scarcely a year elapsed, in which the young prince wras not called out upon some military expedition. He suc¬ cessively assisted at the sieges of Tripoli, Acre, and Roum. In 1298, Prince Mahmoud, his cousin, who held the sove¬ reignty, died, and left Aboulfeda heir. The succession, however, being violently disputed by his two brothers, the court, in consequence of their dissensions, took occasion to supersede all the three ; and the Ayoubites lost the principality which they had enjoyed for more than a cen¬ tury. Aboulfeda, however, by his valour and other emi¬ nent qualities, soon recommended himself to the favour of the Sultan Melik-el-Nassir. He was present, and took an active part in the victory gained at Alkoroum in 1302, and in the still more signal one near Damascus in 1303, by which Syria was for the time delivered from the incursions of the Tartars. But peace was soon followed by inter¬ nal dissensions. The throne of Egypt was disputed with Melik-el-Nassir by Bibars, who at first succeeded in ob¬ taining possession of it. His rival, however, being sup¬ ported by the great men of Syria, among whom Aboulfeda took a conspicuous part, finally triumphed. Aboulfeda, who had always stood well with Melik-el-Nassir, rose then into peculiar favour. The sultan took the first opportuni¬ ty of establishing him in his patrimonial dignity of Prince of Hamah. Honours continued to shower upon him ; he was invested with the distinctive marks of sovereignty, which consisted in the power of coining money, and in hav¬ ing prayers said in his name. The epithet Melik Moway- yad, victorious Prince, was conferred upon him; and it is stated by an Arabian author, that the sultan, in writing, addressed him by the appellation of brother. The rest of Aboulfeda’s life was spent in splendour and tranquillity, devoted to the government of his territory, and to the pursuits of science. Besides cultivating, he patronised literature; and his court became the rendezvous of all the learned men of the East. He conversed with them familiarly, bestowed upon them honours and pensions, and being himself superior to all in learning, felt no jea¬ lousy of their acquirements. During the same period he composed the works which have transmitted his name to posterity. In this enviable manner he spent the period of twenty years, when an illness, of which the particulars are not related, carried him off on the 26th October 1331. He was succeeded by his son Melik-el-Afdhal, of whom little is recorded, and who was the last Prince of Hamah. The two works by which Aboulfeda is known in Europe, are his Geography and his History. The former ranks at least equal to any composed upon that subject by the Arabian writers. It partakes indeed of their general de¬ fects; for, although he seems to have paid more attention to the latitudes and longitudes than the rest of his coun- A B R A B R 41 joulfeda trymen, yet the imperfect application of astronomy, and after.

It is chiefly in the his¬ torical and descriptive parts that he can now be regarded as an authority. Here too his knowledge, as he himself candidly confesses, is chiefly confined to the circle of Moslem dominion ; but within those limits, the information conveyed by him is undoubtedly valuable. His History possesses still higher claims to distinction. His method, as was usual with his countrymen, is entirely that of annals, and is in many parts too much abridged; but the work contains much valuable information with regard to the Saracen, and even to the Greek empire. It is di¬ vided into five parts, beginning at the creation of the world, and ending with the year 1328. There are copies of his Geography in manuscript in the national library of France, in that of the university of Ley¬ den, and in the Bodleian. It has hitherto been published only in fragments, of which the following are the principal. Chorasmia et Mawaralnahra a Joan.

ABRABANEL, Abarbanel, or Avrava^el, Isaac, a celebrated rabbi, descended from King David, and born at Lisbon a. d. 1437. He became counsellor to Alphon- so V. king of Portugal, and afterwards to Ferdinand the a 10 ic, but in 1492 was obliged to leave Spain with the other Jews. In short, after residing at Naples, Corfu, and several other cities, he died at Venice in 1508, aged " V, • Abrabanel passed for one of the most learned of the rabbis; and the Jews gave him the names of the Sage, the Prince, and the Great Politician. We have a com¬ mentary of his on all the Old Testament, which is pretty scarce : he there principally adheres to the literal sense ; aud “is style is clear, but a little diffuse. His other works are, A 1 realise on the Creation of the World; in which etJrfnlA Anstatle’ who imagined that the world was rehflnJ / lre™Se °n1 the ExI)lication of the Prophecies relating to the Messiah, against the Christians: A book concerning Articles of kaith ; and some others less sought bra Abraham. abracadab abracada abracad abraca abrac abra abr ah a sion to Christianity in all his writings, yet he treated Christians with politeness and good manners in the com¬ mon affairs of life. ABRACADABRA, a magical word, recommended by Serenus Samonicus as an antidote against agues and se¬ veral other diseases. It was to be written upon a piece of paper as many times as the word contains letters, omitting the last letter of the former every time, as in the margin,1 and repeated in the same order ; and then sus- » pended about the neck by a linen thread. Abracadabra abracadabra was the name of a god worshipped by the Syrians, the abraca,labr wearing of whose name was a sort of invocation of his aid. ahrn‘-^h ABRAHAM, the father and stock whence the faithful spuing, was the son of Ferah. He was descended from Noah by Shem, from whom he was nine degrees removed. Some fix his birth in the 130th year of Terah’s age, but others place it in his father s 70th year. It is highly pro¬ bable he was born in the city of Ur, in Chaldea, which he and his father left when they went to Canaan, where they remained till the death of Terah ; after which, Abraham resumed his first design of going to Palestine. The Scrip¬ tures mention the several places he stopped at in Canaan; his journey into Egypt, where his wife was carried off from him; his going into Gerar, where Sarah was again taken from him, but restored as before; the victory he obtained over the four kings who had plundered Sodom; his compliance with his wife, who insisted that he should make use of their maid Hagar in order to raise up chil¬ dren ; the covenant God made with him, sealed with the ceremony of circumcision; his obedience to the command of God, who ordered him to offer up his only son as a sa¬ crifice, and how this bloody act was prevented ; his mar¬ riage with Keturah; his death at the age of 175 years; and his interment in the cave of Machpelah, near the body of Sarah his first wife. Abraham is said to have been well skilled in many sciences, and to have written several books. Josephus2 * Jntig. lib. tells us that he taught the Egyptians arithmetic andi. cap. 7, 8. geometry ; and according to Eupolemus and Artapan, he instructed the Phoenicians, as well as the Egyptians, in astronomy. A work which treats of the creation has been long ascribed to him: it is mentioned in the Talmud,3 3 HekW- and the rabbis Chanina and Hoschia used to read it on ger, Hist. the eve before the Sabbath. In the first ages of Christian- Patriarch. ity, according to St Epiphanius,4 an heretical sect, calledtom-iL Sethimans, dispersed a piece which had the title of Abra- ^ hams Revelation. Origen mentions also a treatise sup-nJT posed to have been written by this patriarch. The book 286“. on the creation was printed at Paris in 1552, and translat¬ ed into Latin by Postel: Rittangel, a converted Jew, and professor at Kbnigsberg, gave also a Latin translation of it, with remarks, in 1642. Abraham, Ben Chaila, a Spanish rabbi, in the 13th century, who professed astrology, and assumed the cha¬ racter of a prophet. He pretended to predict the coming of the Messiah, which was to happen in the year 1358; but fortunately he died in 1303, fifty-five years before the time when the prediction was to be fulfilled. He wrote a book, De Nativitatibus, which was printed at Rome in 1545. . Abraham Usque, a Portuguese Jew, who, in conjunc¬ tion with Tobias Athias, translated the Hebrew Bible into Spanish. It was printed at Ferrara in 1553, and reprint- ed in Holland in 1630. This Bible, especially the first edition, which is most valuable, is marked with stars at certain words, which are designed to show that these words are difficult to be understood in the Hebrew, and that they may be used in a different sense. 42 A B R A B R Abraham Abraham, or Abram, Nicholas, a learned Jesuit, born li in the diocese of Toul, in Lorrain, in 1589. He obtained Abraxas. rank of divinity professor in the university of Pont-a- Mouson, which he enjoyed 17 years, and died September 7. 1655. He wrote Notes on Virgil and on Nonnius; A Commentary on some of Cicero’s Orations, in two vols. folio ; an excellent collection of theological pieces in folio, entitled Phams Veteris Testamenti ; and a Hebrew Gram¬ mar m verse. ABRAHAMITES, an order of monks exterminated for idolatry by Theophilus in the ninth century. Also the name of another sect of heretics who had adopted the errors of Paulus. ABRAHAMSDORF, or Abrahamsfalva, a village in Hungary, in the circle of hither Theiss, one of sixteen which were formerly part of Poland, but in 1772 united with Hungary, in consequence of which they all enjoy some peculiar rights of exemption from the Austrian taxes and judicatories. ABRANTES, a town of Portugal, in the province of Estremadura. It is situated on the Tagus, near its junc¬ tion with the Zezare, which is navigable for barges. The situation is delightful, on the upper part of a sloping hill, with a country below it covered with olive trees, and in¬ terspersed with vineyards. One of Buonaparte’s generals had the title of .duke of this place conferred on him. It has 4 monasteries, 1 hospital, 1 poor-house, and 3500 in¬ habitants. Its trade with Lisbon employs 100 boats. ABRASAX, or Abraxas, the supreme god of the Basilidian heretics. It is a mystical or cabbalistic word, composed of the Greek letters a, £, g, a, a, (, which to¬ gether, according to the Grecian mode of numeration, make up the number 365. For Basilides taught, that there were 365 heavens between the earth and the em¬ pyrean ; each of which heavens had its angel or intelli¬ gence, which created it; each of which angels likewise was created by the angel next above it; thus ascending by a scale to the Supreme Being, or first Creator. The Basil idians used the word Abraxas by way of charm or amulet. ABRASION is sometimes used among medical writers for the effect of sharp corrosive medicines or humours in wearing away the natural mucus which covers the mem¬ branes, and particularly those of the stomach and intes¬ tines. The word is composed of the Latin ab and rado, to shave or scrape off. ABRAVANNUS, in Ancient Geography, the name of a promontory and river of Galloway in Scotland, so called from the Celtic term Aber, signifying either the mouth of a river or the confluence of two rivers, and Avon, a river. ABRAUM, in Natural History, a name given by some writers to a species of red clay, used in England by the cabinet-makers, &c. to give a red colour to new mahogany wood. We have it from the Isle of Wight; but it is also found in Germany and Italy. ABRAXAS, an antique stone with the word abraxas engraven on it. They are of various sizes, and most of them as old as the third century. They are frequent in the cabinets of the curious; and a collection of them, as complete as possible, has been desired by several. There is a fine one in the abbey of St Genevieve, which has occa¬ sioned much speculation. Most of them seem to have come from Egypt; whence they are of some use for ex¬ plaining the antiquities of that country. Sometimes they Rave no other inscription besides the word: but others have the names of saints, angels, or Jehovah himself an¬ nexed ; though most usually the name of the Basilidian god. Sometimes there is a representation of Isis sitting on a lotus, or Apis surrounded with stars; sometimes monstrous compositions of animals, obscene images, Phalli Abreast and Ithyphalli. The engraving is rarely good, but the word [I on the reverse is sometimes said to be in a more modern i style than the other. The characters are usually Greek, Hebrew, Coptic, or Hetrurian, and sometimes of a m6ng- rel kind, invented, as it would seem, to render their meaning the more inscrutable. It is disputed whether the Veronica of Montreuil, or the granite obelisk men¬ tioned by Gori, be Abraxases. ABREAST (a sea term), side by side, or opposite to; a situation in which two or more ships lie, with their sides parallel to each other, and their heads equally advanced. This term more particularly regards the line of battle at sea, where on the different occasions of attack, retreat, or pursuit, the several squadrons or divisions of a fleet are obliged to vary their dispositions, and yet maintain a pro¬ per regularity by sailing in right or curved lines. When the line is formed abreast, the whole squadron advances uniformly, the ships being equally distant from and pa¬ rallel to each other, so that the length of each ship forms a right angle with the extent of the squadron or line abreast. The commander-in-chief is always stationed in the centre, and the second and third in command in the centres of their respective squadrons.—Abreast, within the ship, implies on a line with the beam, or by the side of any object aboard ; as, the frigate sprung a leak abreast of the main hatchway, i. e. on the same line with the main hatchway, crossing the ship’s length at right angles, in opposition to afore or abaft the hatchway. ABRIDGEMENT, in Literature, a term signifying the reduction of a book into a smaller compass. “ The mode of reducing,” says the author of the Cu¬ riosities of Literature, “ what the ancients had written in bulky volumes, practised in preceding centuries, came into general use about the fifth. As the number of stu¬ dents and readers diminished, authors neglected litera¬ ture, and were disgusted with composition; for to write is seldom done, but when the writer entertains the hope of finding readers. Instead of original authors, there suddenly arose numbers of abridgers. These men, amidst the prevailing disgust for literature, imagined they should gratify the public by introducing a mode of reading works in a few hours, which otherwise could not be done in many months; and observing that the bulky volumes of the ancients lay buried in dust, without any one conde¬ scending to examine them, the disagreeable necessity in¬ spired them with an invention that might bring those works and themselves into public notice, by the care they took of renovating them. This they imagined to effect by forming abridgements of these ponderous vo¬ lumes. “ All thes?e Abridgers, however, did not follow the same mode. Some contented themselves with making a mere abridgement of their authors, by employing their own ex¬ pressions, or by inconsiderable alterations. Others com¬ posed those abridgements in drawing them from various authors, but from whose works they only took what ap¬ peared to them most worthy of observation, and dressed them in their own style. Others, again, having before them several authors who wrote on the same subject, took passages from each, united them, and thus formed a new work. They executed their design by digesting in com¬ mon-places, and under various titles, the most valuable parts they could collect, from the best authors they read. To these last ingenious scholars we owe the rescue of many valuable fragments of antiquity. They happily preserved the best maxims, the characters of persons, descriptions, and many other subjects which they found interesting in their studies. A B R A B R Abridge¬ ment “ There have been learned men who have censured these Abridgers, as the cause of our having lost so many Abruzzo exce^ent ent*re works of the ancients ; for posterity be- coming less studious, was satisfied with these extracts, and neglected to preserve the originals, whose voluminous size was less attractive. Others on the contrary say, that these Abridgers have not been so prejudicial to literature as some have imagined ; and that had it not been for their care, which snatched many a perishable fragment from that shipwreck of letters which the barbarians occasioned, we should perhaps have had no works of the ancients re¬ maining. “ Abridgers, Compilers, and even Translators, in the present fastidious age, are alike regarded with contempt; yet to form their works with skill requires an exertion of judgment, and frequently of taste, of which their con¬ temners appear to have no conception. It is the great misfortune of such literary labours, that even when per¬ formed with ability, the learned will not be found to want them, and the unlearned have not discernment to appre¬ ciate them.” (DTsraeli’s Curiosities of Literature.) ABRIES, a town in France, in the department of the Upper Alps, and arrondissement of Briancon. It was for¬ merly a portion of Savoy. Inhabitants 2030. ABROGATION, the act of abolishing a law, by au¬ thority of the maker; in which sense the word is syno¬ nymous with abolition, repealing, and revocation. Abrogation stands opposed to rogation: it is distin¬ guished from derogation, which implies the taking away only some part of a law; from subrogation, which denotes the adding a clause to it; from abrogation, which implies the limiting or restraining it; from dispensation, which only sets it aside in a particular instance; and from anti- quation, which is the refusing to pass a law. ABROKANI, or Majllemolli, a kind of muslin, or clear, white, fine cotton cloth, brought from the East In¬ dies, particularly from Bengal. ABROTONUM, in Ancient Geography, a town and harbour on the Mediterranean, one of the three cities that formed Tripoli. ABRUCENA, a town on the district of Guadix, in the province of Granada, in Spain, between the Sierra Ne¬ vada and Jaen. ABRUD-BANYA, a town of Hungary, in the province of Magyoren, in the circle of Weissenburg. It is situated on the river Ampoy, has one Reformed and one Greek church, is the seat of a board of mining, and in its vicinity mines of gold and of silver are wrought. It is in Lat. 46. 14. 9. N. and Long. 23. 49. 3. E. ABRUS, in Botany, the trivial name of the Glycine. ABRUZZO, one of the four provinces into which the continental part of the kingdom of Naples, or of the two Sicilies, was formerly divided, but now the name given to three out of the 17 provinces of the later division of that country. It is, with altered boundaries, now distinguish¬ ed as Abruzzo Ulteriore First, Abruzzo Ulteriore Second, and Abruzzo Citeriore. Abruzzo Ulteriore hirst, is a maritime province on the Adriatic Sea,which is its boundary towards the north¬ east. On the north-west the Papal dominions bound it, on the south-east Abruzzo Citeriore, and on the south¬ west Abruzzo Ulteriore Second. The western part of the province is very mountainous; the highest crest of the Appenines divides it from Abruzzo Ulteriore Second, and extends towards the sea. The district on the sea-coast is flat, but everywhere else hilly. The valleys between the mils possess a rich soil, well watered by rivulets and brooks in the winter and spring, but which are generally dried up in the summer months. These streams either 43 1’u,n mt0 Vv6 P.esGara’ w,llc]l bounds the province towards Abruzzo. Abruzzo Citeriore, or into the Tronto, which is the boun-^V"w dary on the Papal frontier. The extent of the province is 1140 square miles, or 730,600 English acres. The cul¬ tivation is badly conducted, and many districts are almost left in a state of natural wildness. The art of irrio-ation is not understood, nor embankment of the rivers practis¬ ed, so that the best of the land is often rendered useless. There are owners of two or three hundred acres of land,' who scarcely raise sufficient food for their families; ami yet the soil, when tolerably managed, will yield 12 grains of wheat for one. The corn most cultivated and preferred is maize. Hemp and flax are raised, but, like corn, mere¬ ly sufficient for the home supply. Olives, almonds, figs, grapes, and chesnuts, are abundant, as is wood for con¬ struction and fuel. The number of inhabitants is 157,339, according to the late census. They are a hardy, bold, idle, and superstitious, race. The most industrious of them stroll yearly into the territories of the Church to w ork at harvest and in making charcoal, and return home in winter with their wages. The province is divided into two districts, Teramo and Civita di Penne. The city of Teramo is the capital of the province. Abruzzo Ulteriore Second, a province in the conti¬ nental division of the kingdom of Naples. It is an inland district, bounded on the north by the Papal States, on the north-east by Abruzzo Ulteriore First, on the south-east by Abruzzo Citeriore, on the south by the province Terra di Lavora, and on the west by the States of the Church, The extent is 2210 square miles, or 1,414,400 acres. The whole province is nearly covered with mountains of various heights, one of which, the Grand Casso dTtalia, near Aquila, is the loftiest peak of the Appenines. There are no plains ; but among these mountains some beauti¬ ful and fruitful vaileys have been formed by the various streams that run through them. None of the rivers are navigable, but all of them have abundance ofwrater, except in the hottest of the summer months. The largest fresh lake of the kingdom is that of Cellano, 14 miles long, and 9 broad, surrounded with hills. A canal, built by the Romans to carry off the surplus water, has been long neglected and stopped up, but is now in course of being cleaned and opened. The air is generally temperate, and the sirocco is never felt. The cultivation just suffices to provide suf¬ ficient corn for the inhabitants, who, when the maize is dear, make out their subsistence by the help of chesnuts. Olives and vines rarely bring their fruit to full ripeness. Some flax and hemp are raised, and a vast quantity of saffron, which is generally preferred to all other. The sheep produce fine wool when the flocks migrate, and the flesh is good. The cows yield good butter and cheese, which form the chief articles of exportation to the neigh¬ bouring provinces. The inhabitants amount to 249,600. Like all mountaineers, they are a strong and active race, and frugal in their habits. The manufactures are insignifi¬ cant, consisting of some little woollen and linen cloth, some paper, pottery, and wood-ware ; but not sufficient of any for the demand of the territory, which is supplied by the exchange of almonds, figs, saffron, wool, butter, and cheese. The chief city is Aquila. Abruzzo Citeriore, a province in the kingdom of Naples. It is bounded on the north-west by Abruzzo Ulteriore First, on the north-east by the Adriatic Sea, on the south-west by the province Molise, and on the west by that of Abruzzo Ulteriore Second. This pro¬ vince is less hilly than the other two Abruzzos, but the Appenines are extended through the south-west part. They, however, gradually decline in height, and extend themselves in wide plains of sand and pebbles. The rivers 44 A B S Abruzzo all run to the Adriatic, and are very deficient in water II during the summer months. Agriculture is in a very rus13' hcickwai’d state, and the soil is rather ungrateful when labour is bestowed upon it; and the inhabitants prefer the chase and the fishery to it. The corn is sufficient for the population, who grow and consume much more maize and rice than wheat or barley. On the coast some oil and some silk are produced, which, with wine, form the chief export articles. Hemp, flax, liquorice, almonds, and figs, are grown for home consumption. The cattle are more neglected than in the other Abruzzos, though there is ex¬ cellent pasture both for sheep and cows. There are, however, abundance of swine, goats, and asses. The ma¬ nufactures are very insignificant. All the exchange of commodities is carried on by land; for though the pro¬ vince has an extensive frontier to the sea, it has no har¬ bour or secure anchoring places. The extent is 1920 square miles, or 1,228,800 acres. The inhabitants are 222,730. There is but one decent road through the pro¬ vince. The capital is Civita di Chieti, formerly called Teti. ABSALOM, in Scripture History, the son of David by Maacah, was brother to Tamar, David’s daughter, who wras ravished by Amnon, their eldest brother by another mother. Absalom waited two years for an opportunity of revenging the injury done to his sister ; and at last pro¬ cured the assassination of Amnon at a feast which he had prepared for the king’s sons. He took refuge with Talmai, king of Geshur; and was no sooner restored to favour than he engaged the Israelites to revolt from his father. Absalom was defeated in the wood of Ephraim: as he was flying, his hair caught hold of an oak, where he hung till Joab came and thrust him through with three darts. David had expressly ordered his life to be spared, and ex¬ tremely lamented him. The weight of Absalom’s hair, which is stated at “ 200 shekels after the king’s weight,” has occasioned much critical discussion. If, according to some, the Jewish shekel of silver was equal to half an ounce avoirdupois, 200 shekels would be 6^ pounds; or, according to Josephus, if the 200 shekels be equal to 5 minse, and each mina 2^ pounds, the weight of the hair would be 121 pounds, a supposition not very credible. It has been supposed by others, that the shekel here denotes a weight in gold equal to the value of the silver shekel, or half an ounce, which will reduce the weight of the hair to about 5 ounces ; or that the 200 shekels are meant to ex¬ press the value, not the weight. ABSCESS, in Surgery ; from abscedo, to separate ; a cavity containing pus, or a collection of puriform matter in a part: So called, because the parts which were joined are now separated; one part recedes from another, to make way for the collected matter. ABSCISSE, in Conics, a part of the diameter or trans¬ verse axis of a conic section, intercepted between the vertex or some other fixed point and a semiordinate. See Conic Sections. ABSCONSA, a dark lantern used by the monks at the ceremony of burying their dead. ABSENTEE. See Ireland. ABSIMARUS, in History, having dethroned Leontius, cut off his nose and ears, and shut him up in a monastery, was proclaimed by the soldiers emperor of the East, a. d. 698. Leontius himself was also an usurper. He had de¬ throned Justinian II. who afterwards, with the assistance of the Bulgarians, surprised and took Constantinople, and made Absimarus prisoner. Justinian, now settled on the throne, and having both Absimarus and Leontius in his power, loaded them with chains, ordered them to lie down on the ground, and with a barbarous pleasure held a foot on the neck of each for the space of an hour A B S in presence of the people. They were beheaded A. d. Absinth! 705. * ated ABSINTHIATED, any thing tinged or impregnated II with absinthium or wormwood. Bartholin mentions a " u‘ woman whose milk was become absinthiated, and rendered as bitter as gall, by the too liberal use of wormwood. Vinum absinthites, or poculum absinthiatum, “ worm¬ wood wine,” is much spoken of among the ancients as a wholesome drink, and even an antidote against drunken¬ ness. Its medical virtues depend on its aromatic and bit¬ ter qualities. Infused in wine or spirits, it may prove be¬ neficial in cases of indigestion or debility of the stomach. ABSINTHIUM, in Botany, the trivial name of the common wormwood. ABSOLUTE, in a general sense, something that stands free or independent. Absolute is more particularly understood of a being or thing which does not proceed from any cause, or does not subsist by virtue of any other being, considered as its cause ; in which sense God alone is absolute. Absolute, in this sense, is synonymous with independent, and stands opposed to dependent. Absolute also denotes a thing that is free from condi¬ tions or limitations; in which sense the word is synony¬ mous with unconditional. We say, an absolute decree, ab¬ solute promise, absolute obedience. Absolute Government, that in which the prince is left solely to his own will, being not limited to the observance of any laws except those of his own discretion. Absolute Equations, in Astronomy, is the aggregate of the optic and eccentric equations. The apparent inequa¬ lity of a planet’s motion, arising from its not being equally distant from the earth at all times, is called its optic equation, and would subsist even if the planet’s real mo¬ tion were uniform. The eccentric inequality is caused by the planet’s motion being uniform. To illustrate which, conceive the sun to move, or to appear to move, in the circumference of a circle, in whose centre the earth is placed. It is manifest, that if the sun moves uniformly in this circle, it must appear to move uniformly to a spectator on the earth; and in this case there will be no optic nor eccentric equation : but suppose the earth to be placed out of the centre of the circle, and then, though the sun’s motion should be really uniform, it would not appear to be so, when seen from the earth; and in this case there would be an optic equation, without an eccen¬ tric one. Imagine further, the sun’s orbit to be not circu¬ lar but elliptic, and the earth in its focus; it will be as evident that the sun cannot appear to have an uniform motion in such ellipse : so that his motion will then be subject to two equations, the optic and the eccentric. Absolute Number, in Algebra, is any pure number standing in any equation without the conjunction of lite¬ ral characters ; as 2 a? 36 = 48 ; where 36 and 48 are absolute numbers, but 2 is not, as being joined with the letter x. ABSOLUTION, in Civil Law, is a sentence whereby the party accused is declared innocent of the crime laid to his charge. Absolution, in the Canon Law, is a juridical act, whereby the priest declares the sins of such as are peni¬ tent remitted.—The Romanists hold absolution a part of the sacrament of penance ; the council of Trent, sess. xiv. cap. iii. and that of Florence, in the decree ad Armenos, declare the form or essence of the sacrament to lie in the words of absolution, “ I absolve thee of thy sins.” The for¬ mula of absolution, in the Roman church, is absolute; in the Greek church, it is deprecatory; and in the churches of the Reformed, declarative. A B S A B S 45 osolution Absolution is chiefly used among Protestants for a H sentence by which a person who stands excommunicated bstemii. js released or freed from that punishment. ^ J ABSORBENT, in general, any thing possessing the fa¬ culty of absorbing, or swallowing up another. Absorbent Medicines, testaceous powders, or sub¬ stances into which calcareous earth enters, as chalk, crabs eyes, &c. which are taken inwardly, for drying up or ab¬ sorbing any acid or redundant humours in the stomach or intestines. They are likewise applied externally to ulcers or sores with the same intention. Absorbents, or Absorbing Vessels, in Anatomy, a name given promiscuously to the lacteal vessels, lympha¬ tics, and inhalant arteries ; a minute kind of vessels found in animal bodies, which imbibe fluids that come in contact with them. On account of their minuteness and transpa¬ rency, they escape observation in ordinary dissection. They have, however, been detected in every tribe of ani¬ mals, and, in the animals which have been examined, in every part of the body. ABSORPTION, in the animal economy, is the function of the absorbent vessels, or that power by which they take up and propel substances. This power has been as¬ cribed to the operation of different causes, according to tlie theories which physiologists have proposed. Some attribute it to capillary attraction, others to the pressure of the atmosphere, and others to an ambiguous or un¬ known cause, which they denominate suction; for this last is nothing else than the elastic power of one part of the air restoring the equilibrium, which has been destroy¬ ed by the removal or rarefaction of another part. Absorptions of the Earth, a term used by Kircher and others for the sinking in of large tracts of land by means of subterranean commotions, and many other accidents. Pliny tells us, that in his time the mountain Cybotus, with the town of Curites, which stood on its side, were wholly absorbed into the earth, so that not the least trace of either remained; and he records the like fate of the city of 1 antalis in Magnesia, and after it of the mountain Sipylus, both thus absorbed by a violent opening of the earth. Galanis and Gamales, towns once famous in Phoenicia, are recorded to have met the same fate; and the vast promontory called Phegium, in Ethiopia, after a violent earthquake in the night-time, was not to be seen in the morning, the whole having disappeared, and the earth closed over it. These and many other histories, attested by the authors of greatest credit among the an¬ cients, abundantly prove the fact in the earlier ages ; and there have not been wanting too many instances of more modern date. (Kircher’s Mund. Subter. p. 77.) Picus, a lofty mountain in one of the Molucca isles, which was seen at a great distance, and served as a land¬ mark to sailors, was entirely destroyed by an earthquake; and its place is now occupied by a lake, the shores of which correspond exactly to the base of the mountain. In 1556, a similar accident happened in China. A whole province of the mountainous part of the country, with all the inhabitants, sunk in a moment, and was totally swal¬ lowed up: the space which was formerly land was also coveied with an extensive lake of water. And, during the earthquakes which prevailed in the kingdom of Chili, in the year 1646, several whole mountains of the Andes sunk and disappeared. ABSORUS, Apsorus, Absyrtis, Absyrtides, (Stra- b°, Mela, Ptolemy); islands in the Adriatic, in the gulf o Carnero; said to be so called from Absyrtus, Medea’s brother, there slain. They are now called Cherso and Usero. ABSTEMII, in church history, a name given to such persons as could not partake of the cup of the eucharist Abstergent on account of their natural aversion to wine. Calvinists Medicfnes allow these to communicate in the species or bread only, II touching the cup with their lip; which, on the other hand, Absti- is by the Lutherans deemed a profanation. nence. A.BSTERGENT Medicines, those employed for re¬ solving obstructions, concretions, &c. such as soap, &c. ABSTINENCE, in a general sense, the act or habit of refraining from something to which there is a strong pro¬ pensity. Among the Jews, various kinds of abstinence were ordained by their law. The Pythagoreans, when initiated, were enjoined to abstain from animal food, ex¬ cept the remains of sacrifices; and to drink nothing but water, unless in the evening, when they were permitted to take a small portion of wine. Among the primitive Christians, some denied themselves the use of such meats as were prohibited by that law, others regarded this ab¬ stinence with contempt; of which St Paul gives his opin¬ ion, Rom. xiv. 1-3. The council of Jerusalem, which was held by the apostles, enjoined the Christian converts to abstain from meats strangled, from blood, from fornica¬ tion, and from idolatry. Abstinence, as prescribed by the gospel, is intended to -mortify and restrain the passions, to humble our vicious natures, and by that means raise our minds to a due sense of devotion. But there is an¬ other sort of abstinence, which may be called ritual, and consists in abstaining from particular meats at certain times and seasons. It was the spiritual monarchy of the western world which first introduced this ritual absti¬ nence, the rules of which were called rogations ; but gross¬ ly abused from the true nature and design of fasting. In England, abstinence from flesh has been enjoined by statute since the Reformation, particularly on Fridays and Saturdays, on vigils, and on all commonly called/is/a days. The like injunctions were renewed under Queen Eliza¬ beth ; but at the same time it was declared that this was done, not out of motives of religion, as if there were any difference in meats, but in favour of the consumption of fish, and to multiply the number of fishermen and marin¬ ers, as well as to spare the stock of sheep. The great fast, says St Augustin, is to abstain from sin. Abstinence is more particularly used for a spare diet, or a slender parsimonious use of food. Physicians relate wonders of the effects of abstinence in the cure of many disorders, and protracting the term of life. The noble Venetian Cornaro, after all imaginable means had proved vain, so that his life was despaired of at 40, recovered, and lived to near 100, by the mere effect of abstinence; as he himself gives the account. It is indeed surprising to what a great age the primitive Christians of the East, who retired from the persecutions into the deserts of Ara¬ bia and Egypt, lived, healthful and cheerful, on a very little food. Cassian assures us, that the common rate for 24 hours was 12 ounces of bread, and pure water: with such frugal fare St Anthony lived 105 years; James the Hermit, 104; Arsenius, tutor of the Emperor Arcadius, 120; St Epiphanius, 115; Simeon the Stylite, 112; and Romauld, 120. Indeed, we can match these instances of longevity at home. Buchanan informs us, that one Lau¬ rence arrived at the great age of 140 by force of temper¬ ance and labour ; and Spotswood mentions one Kentigern, afterwards called St Mongah or Mungo, who lived to 185 by the same means. Abstinence, however, is to be re¬ commended only as it means a proper regimen; for in general it must have bad consequences when observed without a due regard to constitution, age, strength, &c. According to Dr Cheyne, most of the chronical diseases, the infirmities of old age, and the short lives of English¬ men, are owing to repletion, and may be either cured. 46 A B S A B T Abstract Mathema¬ tics. » Phil. Trans. No. 194. Abstinence prevented, or remedied by abstinence; but then the kinds of abstinence which ought to be observed, either in sick¬ ness or health, are to be deduced from the laws of diet and regimen. Among the inferior animals, we see extraordinary in¬ stances of long abstinence. The serpent kind, in parti¬ cular, bear abstinence to a wonderful degree. We have seen rattle-snakes which had lived many months without any food, yet still retained their vigour and fierceness. Dr Shaw speaks of a couple of cerastes (a sort of Egyptian serpents), which had been kept five years in a bottle close corked, without any sort of food, unless a small quantity of sand in which they coiled themselves up in the bottom of the vessel may be reckoned as such; yet when he saw them, they had newly cast their skins, and were as brisk and lively as if just taken. But it is natural for divers spe¬ cies to pass four, five, or six months every year, without either eating or drinking. Accordingly, the tortoise, bear, dormouse, serpent, &c. are observed regularly to retire, at those seasons, to their respective cells, and hide them¬ selves, some in the caverns of rocks or ruins; others dig holes under ground; others get into woods, and lay them¬ selves up in the clefts of trees; others bury themselves under water, &c. And these animals are found as fat and fleshy, after some months’ abstinence, as before.—Sir G. Ent1 weighed his tortoise several years successively, at its going to earth in October, and coming out again in March; and found, that of four pounds four ounces, it only used to lose about one ounce. We have instances of men passing several months as strictly abstinent as other creatures. In particular, the records of the Tower mention a Scotsman imprisoned for felony, and strictly watched in that fortress for six weeks, during which time he did not take the least sus¬ tenance ; and on this account he obtained his pardon. Numberless instances of extraordinary abstinence, particu¬ larly from morbid causes, are to be found in the different periodical Memoirs, Transactions, Ephemerides, &c. It is to be added, that, in most instances of extraordinary abstinence related by naturalists, there were said to have been apparent marks of a texture of blood and humours, much dike that of the animals above-mentioned. Though it is no improbable opinion that the air itself may furnish something for nutrition, it is cei'tain there are substances of all kinds, animal, vegetable, &c. floating in the atmo¬ sphere, which must be continually taken in by respira¬ tion ; and that an animal body may be nourished there¬ by, is evident in the instance of vipers; which, if taken when first brought forth, and kept from every thing but air, will yet grow very considerably in a few days. So the eggs of lizards are observed to increase in bulk after they are produced; and in like manner the eggs or spawn of fishes grow and are nourished with the water. And hence, say some, it is that cooks, turnspit dogs, &c. though they eat but little, yet are usually fat. ABSTINENTS, or Abstinentes, a set of heretics that appeared in France and Spain about the end of the third century. They are supposed to have borrowed part of their opinions from the Gnostics and Manicheans, because they opposed marriage, condemned the use of flesh meat, and placed the Holy Ghost in the class of created beings. We have, however, no certain account of their peculiar tenets. ABSTRACT, in a general sense, any thing separated from something else. Abstract Ideas, in Metaphysics. See Abstraction. Abstract Mathematics, otherwise called Pure Mathe¬ matics, is that which treats of magnitude or quantity, ab¬ solutely and generally considered, without restriction to any species of particular magnitude; such are Arithmetic Abstract and Geometry. In this sense, abstract mathematics is lumbers opposed to mixed mathematics; wherein simple and ab- *11 stract properties, and the relations of quantities primi- tively considered in pure mathematics, are applied to sensible objects, and by that means become intermixed with physical considerations: such are Hydrostatics, Op¬ tics, Navigation, &c. Abstract Numbers, are assemblages of units, consid¬ ered in themselves, without denoting any particular and determinate things. Thus, six is an abstract number when not applied to any thing; but if we say 6 feet, 6 becomes a concrete number. Abstract Terms, words that are used to express ab¬ stract ideas. Thus beauty, ugliness, whiteness, roundness, life, death, are abstract terms. Abstract, in Literature, a compendious view of any large work; shorter and more superficial than an abridge¬ ment. ABSTRACTION, in Metaphysics, is a term used to denote the mind’s power of considering certain qualities or attributes of an object apart from the rest; or the power which the understanding has of separating the combinations which are presented to it. Abstraction is chiefly employed in these three ways. First, When the mind considers any one part of a thing, in some respect distinct from the whole; as a man’s arm, without the consideration of the rest of the body. Se¬ condly, When we consider the mode of any substance, omitting the substance itself; or when we separately con¬ sider several modes which subsist together in one subject. This abstraction the geometricians make use of when they consider the length of a body separately, which they call a line, omitting the consideration of its breadth and thick¬ ness. Thirdly, It is by abstraction that the mind forms general ideas. Thus, when we would understand a think¬ ing being in general, we gather from our self-conscious¬ ness what it is to think; and omitting those things which have a particular relation to our own minds, or to the human mind, we conceive a thinking being in general. Ideas formed in this manner, which are what we pro¬ perly call abstract ideas, become general representatives of all objects of the same kind. Thus the idea of colour that we receive from chalk, snow, milk, &c. is a repre¬ sentative of all of that kind; and has a name given it, white¬ ness, which signifies the same quality wherever found or imagined. See the article Metaphysics. ABSURDUM, reductio ad absurdum, is a mode of de¬ monstration employed by mathematicians when they prove the truth of a proposition by demonstrating that the con¬ trary is impossible, or leads to an absurdity. It is in this manner that Euclid demonstrates the fourth proposition of the first book of the Elements, by showing that the contrary involves a manifest absurdity, viz. That two straight lines can inclose a space. ABSYRTUS, in heathen mythology, the son of iEetes and Hypsea, and the brother of Medea. The latter run¬ ning away with Jason, after her having assisted him in carrying off the golden fleece, was pursued by her father; when, to stop his progress, she tore Absyrtus in pieces, and scattered his limbs in his way. ABTERODE, a town in the bailiwick of Bilstein, in Hesse-Cassel, in Germany, with 972 inhabitants, who find employment chiefly in making woollen cloth. ABTHANES, in History, a title of honour used by the ancient inhabitants of Scotland, who called their nobles thanes, which in the old Saxon signifies king's ministers; and of these the higher rank were styled abthanes, and those of the lower underthanes. ABU Abu ABU and CANDU, a group of twelve islands in the 'I southern division of the Indian Ocean, to the south of the Maldives, in Lat. 5. 6. S. and Long. 74. 23. E. They are rocky, but have good anchorage, under the shelter of a reef. There are no inhabitants, nor has any good water been found. ABU-ARISCH, the capital of the territory of the same name, on the Red Sea, in a fruitful plain, with rock-salt mines near it. It is in Lat. 16. 45. N. and Long. 42. 33. E. ABUBEKER, or Abu-Becr, the first caliph, the im¬ mediate successor of Mahomet, and one of his first con¬ verts. His original name was Abdulcaaba, signifying ser¬ vant of the caaba or temple, which, after his conversion to Mahometanism, was changed to Abdallah, servant of God; and on the marriage of the prophet with his daughter Ayesha, he received the appellation of Abu-Becr, Father of the virgin. Illustrious by his family, and possessed of immense wealth, his influence and example were power¬ ful means of propagating the faith he had adopted, and in gaining converts to the new religion. Abubeker was a sound believer; and although he lived in the greatest fa¬ miliarity with Mahomet, he had always the highest vene¬ ration for his character. He vouched for the truth of his revelations after his nightly visits to heaven, and thus ob¬ tained the appellation of the faithful. He was employed in every mission of trust or importance, was the constant friend of the prophet, and when he was forced to fly from Mecca, was his only companion. But notwithstanding his blind devotion to Mahometanism, his moderation and prudence were conspicuous in checking the fanatical zeal of the disciples of the new religion on the death of Ma¬ homet. I his event threatened destruction to the doc¬ trines of Islamism. Its followers could not doubt that it had taken place, and they were afraid to believe it. In this uncertainty and fluctuation of belief, Omar drew his sword, and threatened to cut in pieces all who dared to assert that the prophet was dead. Abubeker, with more coolness and wisdom, addressed the people, Is it, says he, Mahomet ivhom you adore, or the God whom he has re¬ vealed to you ? Know thaff this God is alone immortal, aiul that all those whom he has created are subject to death. Appeased and reconciled by this speech, they elected him successor to Mahomet, and ^ie assumed the modest title of caliph, which has continued with all his successors. Ali, the son-in-law of the prophet, regarding the elevation of Abubeker as a violation of his legal rights to the suc¬ cession, refused at first to recognise the appointment, till he was forced by threats into compliance and submission. His partisans, however, still considered him as the legiti¬ mate successor, and their opinion has prevailed among many Mussulmans, who believe that the sovereign authority, both spiritual and temporal, remains with his descendants. Abubeker first collected and digested the revelations of Mahomet, which had hitherto been preserved in detached fragments, or in the memories of the believers ; and to this the Arabians gave the appellation Almoshaf or the Book. He died in the 13th year of the Hegira, respected as a prudent and equitable ruler. ,. ABUCCO, Abocco, or Abochi, a weight used in the kingdom of Pegu. One abucco contains 121 teccalis ; two abuccos make a giro or agire ; two giri, half a hiza ; and a hiza weighs an hundred teccalis; that is, two pounds tive ounces the heavy weight, or three pounds nine ounces the light weight of Venice. ABUCHOW, a village in Russia, in the circle of Bo- goradsk, and government of Moscow, where are mills be- longing to the emperor, from whence 10,000 poods of gun¬ powder are annually delivered. It stands on the river ivliasma, whose stream turns seven mills. ABU 47 ABUKESO, in commerce, the same with Aslan. Abukeso ABUKOR, a town near Lepanto, in the province of || Aimabochte, in Turkey in Europe. Abundant ABULAHOR, a town of Turkey in Europe, on the Number. river Aspre, in the Sandschacor Standard of Joanina, and'^~v'v‘-' province of Romelia. ABULAWO, a town of Russia, in the circle of Kra- piwna, and government of Tula. ABULFARAGIUS, Gregory, son of Aaron, a physi¬ cian, born in 1226, in the city of Malatia, near the source of the Euphrates in Armenia. He followed the profession of his father, and practised with great success; but he acquired a higher reputation by the study of the Greek, Syriac, and Arabic languages, as well as by his knowledge of philosophy and divinity; and he wrote a history which does great honour to his memory. It is written in Arabic, and divided into dynasties. It consists of ten parts, being an epitome of universal history from the creation of the world to his own time. The parts of it relating to the Saracens, Tartar Moguls, and the conquests of Jenghis Khan, are esteemed the most valuable. He professed Christianity, was bishop of Aleppo, and is supposed to have belonged to the sect of the Jacobites. His contempora¬ ries speak of him in a strain of most extravagant panegy¬ ric. He is styled the king of the learned, the pattern of his times, the phoenix of the age, and the croivn of the vir¬ tuous. Dr Pococke published his history with a Latin translation in 1663, in 2 vols. 4to. ABULFAZEL, who is called by Sir William Jones, “ a learned and elegant,” and by others, “ the most ele¬ gant” writer that the East has produced, was vizier and historiographer to the Great Mogul, Akber. We have not been able to discover the year of his birth, but his death took place in 1604, when he was assassinated on his return from a mission to the Decan. According to some writers, this foul act was perpetrated at the instigation of the heir apparent to the throne, who had become jealous of the minister’s influence with the emperor. Akber greatly lamented the loss of a man who was not only an able minister of state, but of such talents as a writer, as to make it a common saying in the East, “ that the neigh¬ bouring monarchs stood more in awe of his pen than of the sword of his master.” He wrote, by the emperor’s command, a history of his reign, which came down to the forty-seventh year, in which he was assassinated. In con¬ nection with this, he also compiled a volume, intended to exhibit a geographical and statistical view of the empire, and of the revenue, household, and expenses of the sove¬ reign. It likewise embraces an account of the religion of the Hindoos, of their sacred books, and their several sects in religion and philosophy. This work, which is fraught with much curious and valuable information, is known under the name of the Ayeen Akbery. It has been trans¬ lated into English with great accuracy by Mr Francis Gladwin. The translation was undertaken and published at Calcutta, under the intelligent patronage of Mr Hast¬ ings. “ Such a work,” he said, in a minute of council, “ could not but prove peculiarly useful; as it comprehends the original constitution of the Mogul Empire, described under the immediate inspection of its founder, and will serve to assist the judgment of the Court of Directors on many points of importance to the first interests of the company.”—The Calcutta edition, published in 1783-6, in three volumes quarto, is a splendid book, and the most valuable in every respect, as the London reprints are by no means accurate. ABUNA, the title given to the archbishop or metropo¬ litan of Abyssinia. ABUNDANT Number, in Arithmetic, is a number, the 48 ABU Abundan- sum of whose aliquot parts is greater than the number tia itself. Thus, the aliquot parts of 12 being 1, 2, 3, 4, and II 6, they make, when added together, 16. An abundant Abu. number is opposed to a deficient number, or that which is remj“Vgreater than all its aliquot parts taken together; as 14, whose aliquot parts are 1, 2, and 7, which makes no more than 10; and to a perfect number, or one U> which its aliquot parts are equal, as 6, whose aliquot parts are 1, 2, and 3. ABUNDANTIA, a heathen divinity, represented in ancient monuments under the figure of a woman with a pleasing aspect, crowned with garlands of flowers, pouring all sorts of fruits out of a horn which she holds in her right hand, and scattering grain with her left, taken pro¬ miscuously from a sheaf of corn. On a medal of Trajan she is represented with two cornucopiae. ABUS, in Ancient Geography, a river of Britain, now the Humber. ABUS AID, Ebn Aljaptu, sultan of the Moguls, suc¬ ceeded his father anno 717 of the Hegira. He was the last monarch of the race of Jenghis Khan, who held the undivided empire of the Moguls; for after his death, which happened the same year that Tamerlane was born, it became a scene of blood and desolation, and was broken into separate sovereignties. ABUSIR, a town of Egypt, twelve hours to the west of Alexandria. It is in a ruinous condition, with remains of an ancient temple, and many scattered vestiges of for¬ mer extent and population. ABUSUMBOL, or Ebsambul, or Ipsambul, a town on the Nile, in Nubia, to the south of the island of Kogos, in Lat. 22. 20. 11. N. and Long. 31. 40. 57. E. About twenty feet above the river is a temple hewn out of the perpendicular face of the rock. At the entrance are six colossal figures of young persons, in bas-relief, and the space between them filled with hieroglyphics which denote a very high antiquity. ABU-TEMAN, an Arabian poet, of whom, though but little can be said, it would be improper altogether to omit, because he was held to be the prince of Arabian poets, during the best periods of Arabian literature. He was born about the year 787; and, happily for him, under so¬ vereigns whose love and patronage of literature made poe¬ tical eminence an unfailing road to wealth and honour. Part of his early life was passed in Egypt, in the servile capacity of administering drink to those who frequented a mosque. It is also said, that he was for some time em¬ ployed in the trade of a weaver at Damascus. But his talents for poetry soon lifted him from this humble sphere, and removed him to Bagdad, where the caliphs loaded him with presents, and treated him with the greatest re¬ spect. If we are to believe the Arabian historians, a single poem sometimes procured for him many thousand pieces of gold. So highly was he esteemed by his countrymen, that it was said “ no one could ever die whose name had been praised in the verses of Abu-Teman 1” His own life was very short, for he died in his fortieth year; “ the -ardour of his mind,” says one of his contemporaries, “hav¬ ing wasted his body, as the blade of an Indian scimitar destroys its scabbard.” Besides being a great original poet, he was the compiler of three collections of select pieces of the poetry of the East; the most esteemed of A B Y which collections is that called the Hamasa. Sir William Abu- Jones speaks of it as a very valuable compilation. Many Teman of the elegant specimens of Arabian poetry contained in '' Professor Carlyle’s well-known work, were translated from pieces contained in this miscellany. A large portion of it, with a Latin version, was annexed by Schultens to his edition of Erpenius’s Arafo'c Grammar,published atLeyden in 1748; and there are also many extracts from it in the collection entitled Anthologia Arabica, published at Jena in 1774. ABUTILON, in Botany, the trivial name of several species of the sida. ABUZOW, a town of Russia, in the circle of Sergatsch, and government of Rishegorod. ABYDOS, in Ancient Geography, anciently a town built by the Milesians, in Asia, on the Hellespont, where it is scarce a mile broad, opposite to Sestos, on the Euro¬ pean side. It was famous for Xerxes’s bridge, and for the loves of Leander and Hero (Musaeus, Ovid); celebrated also for its oysters (Ennius, Virgil). The old castle of the Dardanelles, built by the Turks, lies a little southward of Sestos and Abydos. ABYDUS, in Ancient Geography, an inland town of Egypt, between Ptolemais and Diospolis Parva, famous for the palace of Memnon and the temple of Osiris. ABYLA (Ptolemy, Mela), one of Hercules’s pillars, on the African side, called by the Spaniards Sierra de las Monas, opposite to Calpe in Spain, the other pillar ; sup¬ posed to have been formerly joined, but separated by Her¬ cules, and thus to have given entrance to the sea now call¬ ed the Mediterranean ; the limits of the labours of Hercu¬ les. (Pliny.) ABYSS, in a general sense, denotes something pro¬ found, and, as it were, bottomless. The word is original¬ ly Greek, aCu the Tacazze, which rolls for a great part of its course through deep valleys, choked with luxuriant vegetation, and tenanted only by wild beasts and human savages. It then penetrates the sands of Nubia, and joins the Nile in the district of Berber. The numerous streams of Go* jam unite in forming the Dembea, a great lake in the heart of the kingdom, out of which flows the Azergue, or Blue River, which many of the moderns have obstinately held to be the main stream of the Nile. Bruce, indeed, on viewing its sources, announced himself as having ac¬ complished the object of an arduous journey, by discover¬ ing the springs of that famous river. It is now, however, considered to be a clear point, that when the Blue River, after taking a semicircular sweep through Abyssinia, and passing its precincts, meets the Abiad, or White River, the latter, coming from sources far to the west and in the interior of Africa, is a much deeper and greater stream, and entitled to be considered as the real Nile, to which the other is only a tributary. Abyssinia, though thus mountainous, does not contain many mineral productions; for the gold, of which a good deal passes through it, is brought from countries farther in the interior. It has, however, on its frontier a great plain, about four days’ journey across, covered entirely with salt. There is generally a depth of two feet of perfectly pure and hard salt on the surface ; below, the mineral is coarser and softer. Both the digging for the salt and the carry¬ ing it off are very dangerous operations, from the vicinity of barbarous plundering tribes, always ready to attack those employed, who must therefore be associated in nu¬ merous and well-armed bodies. Abyssinia was evidently included by the ancients un¬ der that wide territory to which they gave the name of Ethiopia, and which includes all Africa south of Egypt, and of the mountain range of Atlas. It formed no part, how¬ ever, of the celebrated Ethiopia, whose capital was Meroe, This region, involved in dim religious mystery, which conquered Egypt, and which Cambyses vainly sought to conquer, comprised the territory along the Upper Nile now known by the name of Nubia. Abyssinia, barred by lofty mountains, by forests, marshes, and deserts, is not recorded as having ever been reached by any land expedition. Neither Petronius, when sent by Augustus against Queen Candace, nor Probus in his expedition, against the Blemmyes, arrived even at Meroe ; and con¬ sequently did not make an approach towards Abyssinia. Herodotus indeed mentions the isle of the Exiles, on which a numerous body of deserters from Psammetichus, king of Egypt, were settled by the Ethiopian monarch. As that historian, however, evidently understands this isle, by which, according to the practice of antiquity, he means a region inclosed by river-channels, to extend along the Nile, which river he understood to come from the west, it would appear that this description must have pointed either to Sennaar, or some region on the Bahr-el-Abiad, and could comprehend no part of the mo¬ dern Abyssinia. The only slight notices which the an¬ cients gleaned respecting that country, were obtained by the way of its coast, situated on the Red Sea. It is a firm article in the national creed of Abys- History, sinia, that the Queen of Sheba, who came from the re¬ motest south to listen to and admire the wisdom of Solo- 50 A B Y S Abyssinia, mon, was their queen ; and that it was Abyssinia which fur- nished the splendid and costly presents which she brought to Jerusalem. They add with equal confidence, that her majesty returned pregnant by that great monarch, and brought forth a son, Menilek, whose posterity, though with some interruption, continued to rule over Abyssinia; the monarchs of which country thus boast themselves to be of the race of Solomon. This genealogy, however deeply root¬ ed in Abyssinian conviction, does not seem tenable on any rational grounds. The two leading features were the pro¬ fusion of aromatics and the numerous camels. But the camel is an animal decidedly Arabian, has never been na¬ turalized in Abyssinia, nor is at all suited to the rugged surface of that country ; and even if an Abyssinian queen had possessed a stock of these animals, she would have had no convenience, or even possibility, in that era of na¬ vigation, of transporting them across the Arabian Gulf. The abundance of spices is equally foreign to the rugged soil of Abyssinia, and characteristic of that of Sabea, or the happy Arabia of the classic writers, to which, indeed, every indication points as identical with the Sheba of Scripture. The commerce between Sheba and Judea is often mentioned in the sacred writings, and always as a land intercourse, carried on by camels, and in numerous caravans. It may be observed, also, that the inspired writers nowhere give the least hint of that species of in¬ timacy between Solomon and her majesty, upon which the Abyssinians found this genealogical claim. Strabo has given some notices of Abyssinia, not in con¬ nection with Egypt or with Africa, but with Arabia, as forming the western coast of the Arabian Gulf. It would be difficult, and not very edifying, to verify the successive chain of his positions ; but we may recognise already the leading features which distinguish modern Abyssinia ; the vast herds and huntings of the elephant; the extreme rude¬ ness of many among the native tribes, living in caves under the shelter of trees; the prevalence of barbarous and dissolute manners ; the use of blood as an article of diet; copious libations of hydromel among the higher ranks, and of an infusion of grain among the lower. He represents them as wrapping pieces of flesh in skins, and swallowing both together; probably an erroneous ver¬ sion of the custom of wrapping slices of meat in teff cakes, and stuffing them down in huge mouthfuls. After a long range of this coast came another, producing in¬ cense, aromatics, and even a species of cinnamon. This coast, evidently that of Berbera, terminated in the Southern Horn; the region beyond which was unknown to Strabo, and to Artemidorus, from whom his information was chiefly derived. An important series of early Abyssinian history has been disclosed by a very slight and casual circumstance. An Egyptian monk, named Cosmas Indicopleustes, having penetrated into Abyssinia, was employed by Elesbaan, the king, to copy two inscriptions on a chair and small column of white marble, which had been erected at the port of Adulis. One of these inscriptions commemorates con¬ quests made in Asia by Ptolemy Euergetes, king of Egypt; the other relates conquests which extended over the great¬ er part of Abyssinia, the provinces of which are mention¬ ed almost under their modern names. Such extensive dominion obtained by Euergetes in this part of Africa excited considerable surprise, especially as no hint of it had been given in any of the Greek writers. Mr Salt copied at Axum a tablet, in which similar exploits, al¬ most in the same terms, are ascribed to Aeizanes, king of the Axumites; and considering the silence of ancient authorities, and that such an extent of Egyptian conquest was rather improbable, he inclines to believe that the S I N I A. second inscription of Cosmas, the commencement of which Abyssinia, had been obliterated, related not to Euergetes, but tov-^V^ Aeizanes, and was only a repetition of the Axum inscrip¬ tion. Dr Vincent, however, still adhered to the opinion which makes Ptolemy the subject of both these inscrip¬ tions, and consequently supposed him to have made the conquest of Abyssinia. Some notices respecting the early state of Abyssinia are found in the work entitled Periplus of the Erythrean Sea, written by Arrian, a merchant of Alexandria, and intended seemingly as a coasting guide for the merchants of that capital. In this work Adulis, situated near the modern Masuah, is described as the great emporium of this region, the trade of which consisted chiefly in the exportation of fine ivory, and rhinoceros’ horns ; in return for which, they imported wine, oil, and many manufactures and luxuries produced in the Roman empire. The ivory was brought chiefly from Coloe, situated three days’ jour¬ ney in the interior; while five days beyond was Axum, the metropolis, and a city of great magnificence, as its ruins still attest. The coast beyond Adulis, forming now the territory of the Baharnegash, was ruled by a prince called Zoskales, who is described as highly polished and intelligent, and as giving the most hospitable reception to the strangers who visited this coast. Abyssinia appears thus by its intercourse with Egypt to have acquired a degree of improvement and refinement which it lost at a subsequent period. The first event in the modern history of Abyssinia was the introduction of Christianity by Frumentius, in the fourth century. That religion was then embraced by the court and a great proportion of the inhabitants; and the church of Abyssinia has since, with a short interval, dur¬ ing which the Romish religion prevailed, continued sub¬ ject to the patriarch of Alexandria, and has observed the peculiar doctrines and ritual of the Alexandrian church. Soon after this period reigned Elesbaan, the most power¬ ful and only conquering prince that ever occupied the throne of Abyssinia. Involved by religious antipathies in hostility with the Sabaeans or Homerites, on the op¬ posite coast of Arabia Felix, he invaded, and appears to have made himself completely master of that country. He assembled next a formidable force, with which he ad¬ vanced and laid siege to the already sacred city of Mecca. Tradition represents his army as partly mounted upon ele¬ phants, from which this expedition was termed the war of the elephant. According to the Arabian historians, a miraculous shower of stones destroyed the Ethiopian army; and we may probably conclude that famine and disease, in this barren and dreary region, thinned its ranks, and com¬ pelled it to a disastrous retreat. Notwithstanding this check, the Ethiopian monarchs ap¬ pear to have held sway over a considerable part of Abyssi¬ nia, till the time when the rise of the religion of Mahomet, and its diffusion by force of arms, changed the face of the East. The Mahometans boast that they established their faith in Abyssinia; but no tradition or history of that country gives any countenance to the assertion, nor does its present state exhibit the least vestige of such a change. It appears, however, that they were driven before this torrent of fanatical conquest out of all their possessions in Arabia; that Islamism even crossed the sea, and estab- lished itself in Adel and other territories, by which Abys¬ sinia is closely hemmed in, and with whose people she was ever after involved in rooted hostility, both religious and political. J 6 From this time we are reduced to the dim lights of Abyssinian tradition, which appear, however, to record a remarkable revolution. The Mahometan conquest had AB Y S byssinia. driven before it a considerable number of Jews, who, amid the calamities of their country, had established themselves in different parts of Arabia. They sought refuge in Abys¬ sinia, where they became numerous and powerful, and even established an independent dominion in the province of Samen. Judith, a Jewish princess, possessed of more than manly courage, and ruthless ambition, conceived the de¬ sign of usurping for herself and her country the entire so¬ vereignty of the kingdom. Availing herself of the singu¬ lar custom of immuring the whole royal family on the top of a mountain, she gained possession of this post, and made a general massacre of all those who could advance any claim to the throne. The infant king, however, was carried off by some faithful adherents, and conveyed to Shoa, where his authority was acknowledged ; while Judith reigned for forty years over the rest of the kingdom, and transmitted the crown to her posterity. In 1268, however, the house of Solomon, as it was called, (chiefly, it is said, through the influence of Tecla Haimanout, a monk highly revered for sanctity,) was restored in the person of Icon Amlac. From the time of Icon Amlac the Abyssinians appear to have kept regular annals, and record a list of successive kings. Mr Bruce has even drawn up from these annals a somewhat detailed history of Abyssinia. But a narrative containing only the contests of these barbarous tribes, mingled with superstition and fable, and illumined by few traits of honour and generosity, is little calculated to edify or interest. For a long time it was diversified chiefly by the wars with Adel, a country situated along the coast of the Arabian Gulf. The Adelians had embraced the Mos¬ lem creed, so that national antipathies were heightened by religious bigotry, which rages so fiercely in uninformed minds. The war was therefore carried on with excessive fury, each party signalizing their victory by burning towns and villages, and making a general massacre of the people. After a contest of several centuries, Adel appears to have been completely humbled, and is no longer mentioned among the enemies of Abyssinia. Violent dissensions then arose on the subject of religion. The Romish faith was introduced by a succession of missionaries from Europe; and several of the kings not only embraced, but endeavoured to impose this religion by violence upon their subjects. This gave rise to civil wars, which did not terminate even after the missionaries had been banished, the Catholic system abolished, and the nation had been replaced under the spiritual sway of the Patriarch of Alexandria. About two centuries ago, Abyssinia began to suffer from a new and formidable enemy, by which she has ever since been more and more hardly pressed. From the southern interior regions the Galla, a negro and Pagan race of the most uncouth and savage aspect, and surpassing in ferocity even the Abyssinians themselves, began a series of de¬ solating inroads, sparing neither age nor sex. For a long time they succeeded only in desultory incursions, and were uniformly routed in the open field; but at last, taking advantage of the dissensions in which the kingdom was still plunged, they insinuated themselves into the ser¬ vice of different chiefs, and acquired a degree of discipline which rendered them truly formidable. They have thus finally succeeded in overrunning all the central and finest portions of the kingdom, and leaving to the native rulers only two detached and severed portions. rogress of After this rapid sketch of Abyssinian history, it will be •iscovery. a more interesting object to trace the steps by which the country was penetrated and explored by Europeans, and their observations on the peculiar and striking features of nature and society which it presents. About the year 330, an ecclesiastic named Frumentius, / S I N I A. 51 who had been travelling with his relation, Meropius, a Abyssinia. Tyrian philosopher, and who, at an island in the Red Sea,^-^^-^ had become acquainted with some Abyssinians, represented to Athanasius, the patriarch of Alexandria, the wish of these people to have Christianity introduced into their cquntry. Frumentius was accordingly consecrated Bishop of Axum by the patriarch, and appears to have made many converts among the Abyssinians. But as Constantine the Roman Emperor had embraced Arianism, and was at va¬ riance with the patriarch of Alexandria, he was desirous to recall Frumentius, either that he might appoint an Arian bishop, or that Frumentius might be re-consecrated by one of that persuasion. With this view he wrote a letter to the monarch of Abyssinia, By whom this letter was conveyed is not certain, though it is probable that it was by a person named Theophilus, who travelled into that country about A. d. 333. The only notice which re¬ mains of the journey of Theophilus is given by Philo- storgius (Hist. JEccles.), and it is very meagre. Theophilus found the descendants of some Syrians in Abyssinia, sprung, he supposes, from a Syrian colony planted there in the time of Alexander the Great. In the year 533, the conquests of the Abyssinians in Arabia, and the warm professions of friendship which they held out to the Roman empire, induced Justinian to send an embassy into that remote country, with the hope of persuading its sovereign to employ his forces then in Arabia against the Persian monarch. At this period the Abyssinians were acquainted with the arts of navigation, and had recently imbibed the spirit of trade, and acquired the sea-port of Adule, from which they penetrated along the African coast, as far as the equator, in search of gold, emeralds, and aromatics. For this important commission Justinian selected Nonnosus, descended from a family of ambassadors. He took the route of the Nile, from which he crossed to the Red Sea, and landed at the port of Adule. Though the distance of this place from Axnm, at that period the residence of the sovereigns of Abys¬ sinia, is only fifty leagues, yet the winding passes of the mountains which lie between them detained Nonnosus fifteen days. He was received with great pomp and fa¬ vour by the Abyssinian monarch, Amda, or Ameda; but we are not very distinctly informed as to the fate of his mission. Of his original narrative, some extracts only are preserved in the JBibliotheca of Photius, and in the Chro- nographia of John Malala. From these, among other particulars, we learn that Nonnosus saw, in his passage through the forests which intervene between Adule and Axum, an immense number of wild elephants ; and that the Abyssinian monarch gave audience in an open field, seated on a lofty chariot drawn by four elephants superb¬ ly caparisoned, and surrounded by his nobles and musi¬ cians. In his hand he held two javelins, and a light shield; his clothing was a linen garment and fillet; and though thus imperfectly covered, he displayed a profu¬ sion of gold chains, collars, and bracelets, adorned with pearls and precious stones. Nonnosus represents Axum as large and populous. In detailing his passage over the mountains of Taranta, he remarks the great contrast of the seasons on different sides of it; from Ave to the coast, it was summer and harvest time; whereas from Ave to Axum, and the rest of Abyssinia, it was winter. The truth of this observation is amply confirmed by Mr Salt. About the same period Cosmas, surnamed Indico- pleustes, or the Indian Navigator, visited Adule. It was the design of this author, in publishing his work entitled Topographia Christiana, to confute the heretical opinion that the earth is a globe, and offer proofs that it was a flat oblong, as represented in the Scriptures. His voyage 52 , A B Y S Abyssinia, was performed A. d. 522, and his book published at Alex- andria a. d. 547. Photius, to whom we are indebted for many curious extracts from works now lost, gives some interesting passages from it; and the complete work was published by Montfaucon, at Paris, in 1707, in the Nova Collectio Patmim, tom. ii. The most valuable part of it has been published in French and Greek, by Melchisidec Thevenot, in his Relations de Divers Voyages Curieux, non encore publiees ou traduites, Paris, 1682. To this author we are indebted for the Adulic inscriptions. It appears that Elesbaan, king of the Axumites, had order¬ ed the governor of Adule to send him a copy of these in¬ scriptions ; and the governor employed Cosmas, who hap¬ pened to be there at that time, and one Menas, a mer¬ chant, for that purpose. Till Mr Salt examined these inscriptions, during his first journey, they had always been regarded as forming only one; though in this view their meaning was not very clear, and they were at variance with authenticated history : but he satisfactorily proved, that instead of being a single inscription, referring ex¬ clusively to Ptolemy Euergetes, there were two distinct inscriptions, one of which refers to Ptolemy, and the other to the affairs of Abyssinia. The former inscription, among other things, mentions that Ptolemy and his father were the first that brought elephants from the Troglodytes and Ethiopia. Besides the interesting information which Cosmas af¬ fords respecting the port and inscription of Adule, he particularly describes the trade of the Axumites along the African coast of Barbaria or Zingi, and as far as Trapobane, Ceylon ; and mentions, that every other year the king of Axum sent several persons of distinction to traffic with the natives of Agow for gold, which they bartered for cattle, salt, and iron. The journey com¬ monly occupied six months. He represents the fountains of the Nile as in the vicinity of Agow, which sufficiently points it out as the country of the Agows mentioned by Peter Paez, who travelled in Abyssinia in the beginning of the seventeenth century. Respecting Abyssinia, the notices of travellers are few and very meagre, from the time of Cosmas and Nonnosus, to the conclusion of the fifteenth century. We find it mentioned by Marco Polo, and by Ibn El Wardi, an Ara¬ bian author ; and some slight notices, particularly of the religious missions into that country, till the year 1500, are supplied by Renaudot, from the Coptic writers, in his Historia Patriarcharum Alexandrinormn, Paris, 1713. At the close of the fifteenth century, the Portuguese missions into Abyssinia commenced: they originated in rather a singular circumstance. John II. king of Portugal was extremely anxious to discover the residence of Prester John, who had long been represented in Europe as a Christian sovereign of great power, ruling somewhere in the centre of Asia. For this purpose, John sent Peter Covilham and Alphonso or Michael de Payva into Asia: the latter soon died, but the former, during his abode on the western coasts of the Red Sea, hearing much of the Abyssinian emperor, and of his being a Christian, con¬ cluded that he had found the object of his search. He immediately conveyed this information to his own court, and proceeded himself to Shoa, then the residence of the Negush, or monarch of Abyssinia. He was received and treated with great kindness and respect; but, according to the usual policy of the Abyssinian court at that period, he was not permitted to leave the country. An account of his residence is given by Damiano Goez, in his Legatio S I N I A. Magni Indorum Presb. Joan, ad Emanuel Lusitania;, Abyssinj Antwerp, 1552. King Emanuel, who was desirous oP^va maintaining an intercourse with the sovereign of Abys¬ sinia, (not less from commercial and political than religious motives,) sent an embassy into that country in the year 1520. At the head of this embassy he placed the famous Edward Galvan, who had been secretary of state, and ambassador in France, Germany, and Rome. The selec¬ tion of such a man points out the importance which Emanuel attached to this mission. But unfortunately, Galvan, being extremely old, was unequal to the fatigues of so long and dangerous a journey, and died soon after the embassy entered the Red Sea. In his stead Rodri¬ guez de Lima was appointed; and Francisco Alvarez, who had been chaplain to Galvan, was continued in the same office by Rodriguez. Their journey from the coast of the Red Sea was long and troublesome, on account of the heat of the climate and the badness of the roads; but they arrived at the Abyssinian court on the 12th of April 1520, where they were received with much splendour and courtesy by the Emperor David. They were detained in Abyssinia six years, from various causes ; and on their de¬ parture, the emperor requested Rodriguez to leave behind him his physician, John Bermudez, and a painter of his retinue, with which request the ambassador complied. Alvarez wrote a minute account of Abyssinia, of which there are several editions ;—that published by himself at Lisbon in 1540; a Spanish translation from the Portuguese, published at Antwerp in 1557 ; an Italian translation from the Portuguese manuscript, published by Ramusio in his Collection of Voyages, lib. i., (which differs materially from the Lisbon edition) ; a French translation in 1558; and an English translation, in Purchas’s Collection of Voyages. The value and accuracy of this author’s state¬ ments have been differently appreciated; but it seems probable that several fabrications were published in his name; for Damiano Goez asserts that he had seen a journal Avritten by Alvarez, very different from most of the published works.1 In some respects, the descrip¬ tion which he gives of Abyssinia is extremely valuable. No European traveller, since his time, has visited Angot, Amhara, and Shoa; the first a region occupied by the Pagan Galla, and bordering with some barbarous tribes near the Red Sea. This traveller visited Axum a short time before it was almost totally destroyed by the Turkish invasion, and he describes it as a large and beautiful place. According to him, none of the cities of Abyssinia contained more than fifteen hundred houses; a statement with which the assertion of Bruce, that Gondar, when he was there; contained ten thousand families, can hardly be reconciled. In the year 1538, Bermudez was sent back to Portugal, as ambassador from the Abyssinian monarch; and after a short abode at Lisbon, he was ordered to return by the way of Goa, and take from that place some troops to re¬ inforce the Abyssinian, who at this period had been com¬ pelled to take shelter from the Moors in the mountainous part of his kingdom. The reinforcement was landed at Massowa, and after a difficult journey through the moun¬ tainous passes and defiles, they joined the emperor. Ber¬ mudez published an account of his journey at Lisbon in 1565. There are also editions of it published at the same place in 1569 and 1615, which are very scarce. It was translated into English by Purchas {Pilgrims, 1. vii. c. vii. p. 1149), and from thence into French by La Croze, (Christianisme d Ethiope, p. 92—265.) But the greater part of his work relates to the victories, defeat, and death 1 The translation of Ramusio was made from a manuscript supplied by Goez. ABYSSINIA. 53 »vssirtia. of the Portuguese general, Christopher de Gama; and is society of Jesuits called Antonio de Angelis, who was Abyssinia, principally valuable from the description which he gives famous for his skill in the Amharie language. In of some, otherwise little known, parts of the country, Alphonso Mendez was sent patriarch into Abyssinia.

The Portuguese having lost their credit and influence in Abyssinia by the haughty behaviour of Mendez-, the French resolved to use their endeavours to establish themselves in that country; and for this purpose Louis XIV. wrote a letter to the father of the emperor, who wras then on the throne, which reached him, though by what means we are not informed. At the same time in¬ structions were sent to M. Maillet, the French consul at Cairo, to second the plans of his court; and accordingly, having learned that the emperor was ill, he dispatched Poncet, a physician, to cure him. Along with Poncet was sent, by the influence of the Jesuits, Father de Bre- vedent, a man particularly conversant in astronomy. They embarked on the Nile on the 10th of June 1698, and ar¬ rived within a day and half’s journey of Gondar on the 3d of July of the following year. Here the father died, and Poncet, having rested himself till the 21st of the same month, set out for Gondar. He particularly describes the public audience which was granted him by the emperor, and his rich and splendid attire. Respecting the latter, and also in what he says concerning Gondar, his accounts are considerably at variance with the relations of the Por¬ tuguese missionaries : hence the fidelity of his work has been called in question, especially by Le Grand, though on no sufficient grounds. Having succeeded in curing the Abyssinian monarch, he set out from Gondar in the summer of 1700, by the way of Massowa, and arrived safe in France, where he published a distinct account of his journey. A translation of it is given in Lockman’s Tra¬ vels of the Jesuits. The learned works of Ludolphus— Historia Ethiopica, Francof. 1681 ; Commentarius in Historiam Ethiopicam, Francof. 1691 ; and Relatio Nova, &c. 1693, must not be passed over: for though he chiefly compiled them from the writings of the Portuguese mis¬ sionaries already mentioned, he was enabled to add con¬ siderably to their stock of information, by means of his great knowledge of the Ethiopian language,—by his conversations with Gregory, an intelligent and liberal Abyssinian priest, whom he invited from Rome to the court of Saxe-Gotha, and by the report of Morat, an Armenian merchant, who had often been in Abyssinia. The Theologia Ethiopica of Gregory is published in Fabricius’s Lux Evangelii. In 1750, three Franciscans succeeded in penetrating as far as Gondar. From this time, Abyssinia was not reach¬ ed by any European traveller, till the journey of Bruce. Bruce’s At the time when Mr Bruce entered Abyssinia, it was journey, rent by civil war. The king Yasous, otherwise popular, had married a Galla princess, an unpopular step, in con¬ sequence of which an inveterate prejudice against her, her family, and the king himself,, became rooted in the mind of the Abyssinians. The eldest son, after suc¬ ceeding to the throne, having died, not without sus¬ picion of poison, was succeeded by loas, the son of this Galla queen; but the evident preference which he show¬ ed for his relations belonging to this hated race, excited a violent discontent, which issued in the rebellion of Mariam-Barea, governor of the great province of Be- gemder. The king was obliged to call in the aid of Suhul Michael, the almost independent governor of Tigre. Michael immediately obeyed the call, and soon crushed Mariam-Barea, who sought refuge among the Galla, by whom he was killed. Michael himself, however, now the real master of the kingdom, could not brook the ascend¬ ancy of the king s Galla favourites; and having involved himself in a quarrel with Fasil, the most powerful among that body, both parties took arms. Michael gained a SIN I A. complete victory, after which he put the king to death, Abys?; and substituted in his place Hannes, an old man, brother to the late monarch, in whose name he administered the affairs of the kingdom with absolute sway. He had be¬ fore increased his power by marrying Ozoro Esther, widow of Mariam-Barea, and reckoned the greatest beauty in the kingdom. Such was the state of affairs when Mr Bruce entered Abyssinia; and as it is to him chiefly that we are indebted for wrhat we know of the remarkable features of that country, it must be interesting to introduce here at some length the particulars of his journey. On the 15th of November 1769, Mr Bruce, with two guides, left Arkeeko, on the eastern coast of Africa, and proceeded southwards for Gondar, the capital of Abys¬ sinia. After an hour’s journey, he pitched his tent near a pit full of rain water, where he remained all day; and being detained by some arrangements with his guides, did not finally set out till the evening of the 16th. For the short space they had travelled, the ground was covered with grass broader in the leaf than ours; but in a little time the soil became hard, dry, gravelly, and full of acacia, or Egyp¬ tian thorn. On the 17th, they changed their course from south to west, and soon arrived at a range of mountains standing so close to one another, that there was no passage between them except what was worn by torrents; the bed of one of which consequently now became their road. In the evening they pitched their tent at some distance from this torrent, which contained scarcely any water when they left it; but all the afternoon there had been an ap¬ pearance of rain, with much thunder and lightning at a distance. On a sudden they heard a noise among the mountains louder than thunder; and instantly saw the torrent, swollen immensely by the distant rains, running like a rapid river, and the foremost part of it present¬ ing a body of water about the height of a man. Having run for some time thus violently, the current, no longer supplied by the rains, began to diminish, and by the next morning was entirely gone. Among these mountains the nights are cold even in summer. On the 18th the journey was resumed, following the bed of the torrent, now almost dry, though the stones were rendered very slippery by the quantity of rain which had fallen. Leaving this disagreeable road, they came to a fine rivulet; which being the first clear water they had seen from the time Mr Bruce left Syria, was exceedingly agreeable. They proceeded along the banks of this river for some time; and soon after leaving it, they came to another of the same kind; but next day were obliged to resume their course in the bed of a torrent. The moun¬ tains in this part of the world are excessively rugged and full of precipices, entirely destitute of soil, and covered with loose stones of a black colour. On the side of the torrent in which they marched, however, there grew very large sycamore trees, some of them little less than 7^ feet in diameter. Their branches afforded shelter to an infi¬ nite number of birds, many of them without song, but others having notes very different from the European kinds, and peculiar to the continent of Africa. Most of those which had very beautiful colours were of the jay or magpie kind. The trees were loaded with figs; but they came to nothing, by reason of the ignorance of the sa¬ vages, who knew not the process of caprification. The sti earns of water themselves, which at this season were ound so delightful, run only after October; they appear on the other side of the mountains when the summer rams in Abyssinia are ceasing; at other times no water is to be met with, excepting what is contained in stag¬ nant pools. On the 20th of November they began to ascend the AB Y S yssinia. high mountain of Taranta. Their road was now exceed- 'W-^'ingly rugged and uneven, intersected with monstrous gullies and holes made by the torrents, as well as by huge fragments of rocks which had tumbled down. It was with the utmost difficulty that they could carry the astrono¬ mical instruments up the hill; in which work Mr Bruce himself, and one of his attendants named Yasine, a Moor, bore a principal share. The only misfortune they met with was, that their asses, being unloaded, and committed to the care of a single person, refused to ascend this barren mountain; and in spite of all that their drivers could do, set off at a brisk trot for the fertile plains be¬ low. Luckily, however, they were afterwards recovered by four Moors sent after them, and the journey resumed without any material interruption. Taranta is so destitute of earth, that there was no pos¬ sibility of pitching a tent upon it; so that our travellers were obliged to take up their lodging in one of the caves with which it abounds. The under part of the mountain produces in great plenty the tree called kolquall, which was here observed in greater perfection than in any other place throughout the whole journey. The middle part produced olives, which bore no fruit; and the upper part was covered with the oxycedras, or Virginia cedar, called arze in the language of the country. On the top is a small village named Halai, inhabited by poor shepherds, who keep the flocks of the wealthy inhabitants of the town of Dixan below. They are of a dark complexion, inclining to yellow; their hair black, and curled artificial¬ ly by means of a stick, and which our author supposes to be the same with the crisping-pin mentioned Isa. iii. 22. The men have a girdle of coarse cotton cloth, swathed six times round their middle ; and they carry along with them two lances, and a shield made of bulls’ hides. Be¬ sides these weapons, they have in their girdles a crooked knife with a blade about sixteen inches in length, and three in breadth at the lower part. There is here great plenty of cattle of all kinds ; the cows generally milk-white, with dewlaps hanging down to their knees; their horns wide like those of the Lincolnshire cattle, and their hair like silk. The sheep are all black, both here and throughout the province of Tigre ; having hair upon them instead of wool, like the rest of the sheep within the tropics, but remarkable for its lustre and softness, without any bristly quality. On the top of the mountain is a plain, which, at the time our author was there, they had sown with wheat. The air seemed excessively cold, though the barometer was not below 59° in the evening. On the west side the cedars, which on other parts are very beautiful, degene¬ rate into small shrubs and bushes. The road down this mountain was for some time not inferior in ruggedness to that by which they had ascend¬ ed ; but as they approached Dixan, it improved consid¬ erably. This is the first town on the Abyssinian side of Taranta. It is seated on the top of a hill of a form exact¬ ly conical, surrounded by a deep valley like a ditch ; and there is no access to it but by a path which winds round the hill. The inhabitants were formerly exterminated by Michael Ras ; and the succeeding race were found by Mr Bruce composed of the worst characters from the terri¬ tories of the Baharnagash and the province of Tigre, on both of which it borders. Here he was in danger from the treachery of his guide Saloome, who wished to have decoyed him into the power of some assassins. Finding that this could not be done, he surrounded Mr Bruce and his retinue with a body of armed men; but they were dispersed by the authority of Hagi Abdelcarder, who had received orders to provide for the safety of the travellers. T he only trade carried on here is that of buying and sell- 55 ing slaves, who are stolen from Abyssinia, chiefly by the Abyssinia, priests, and sent into Arabia and India. The next stage was from Dixan to Adowa, capital of the province of Tigre. Leaving Dixan on the 25th of November, they pitched their tent the first night under a large spreading tree called daroo, which, Mr Bruce says, was one of the finest he saw in Abyssinia, being about 7^ feet in diameter. They had been joined by some Moors driving 20 loaded asses and two bulls, which in that coun¬ try are likewise used as beasts of burden. Here, our au- * thor says, he recovered a tranquillity of mind which he had not enjoyed since his arrival at Masuah; they were now entirely w ithout the dominions of the naybe, and en¬ tered into those of the emperor. Saloome attended them for some way, and seemed disposed to proceed; but one of the company, who belonged to the Abyssinian mo¬ narch, having made a mark in the ground w ith his knife, told him, that if he proceeded one step beyond that, he would bind him hand and foot, and leave him to be de¬ voured by wild beasts. Being now in a great measure delivered from their fears and embarrassments, the company proceeded on their journey with pleasure, through a much better country than they had hitherto passed. In some places it was covered with wild oats, wood, high bent grass, &c. but in not a few places rocky and uneven. Great flocks of a bird as large as a turkey, called in the Amharic language erkoom, w'ere seen in some places. A large animal of the goat kind, called agazan, was found dead and newly killed by a lion. It was about the size of a large ass, and afforded a plentiful repast. Numbers of kolquall trees were also seen; and the sides of the river Habesh were adorned with a beautiful tree of the same name with the stream. There wrere in this place also many flowers of various kinds, particularly jessamine. The mountains of Adowa, which they came in sight of on the 5th of De¬ cember, are totally unlike any thing to be met with in Europe; their sides being all perpendicular rocks, like steeples or obelisks of many different forms. Adowa, though the capital of an extensive province or kingdom, does not contain above 300 houses; it occupies nevertheless a large space, by reason of the inclosures of a tree called ivanzey, which surround each of the houses. It stands on the declivity of a bill, situated on the west side of a small plain surrounded by mountains. It is watered by three rivulets, which never become dry, even in the greatest heats. A manufacture is carried on here of a kind of coarse cotton cloth, wdiich passes for money throughout all Abyssinia. The houses are built of rough stone cemented with mud; lime being only used in the construction of those at Gondar, and even there it is very bad. Our traveller was very hospitably entertained at Adowa, by one Janni, with whom he resided during his stay there. Leaving it on the 17th of December, he visited the ruins of Axum, once the capital of the empire. He found 40 obelisks, but without any hieroglyphics. A large one is still standing, but the two largest have fallen. There is also a curious obelisk, of which he gives a figure, with other antiquities which our limits will not allow us to en¬ large upon. The town has at present about 600 houses, and carries on manufactures of the coarse cotton cloth al¬ ready mentioned. It is watered by a small stream which flows all the year, and it is received into a fine basin, 150 feet square, where it is collected for the use of the neigh¬ bouring gardens. Its latitude was found by Mr Bruce to be 14. 6. 36. N. On the 20th of January 1770, our traveller set out from Axum. The road was at first smooth and pleasant, SIN I A. 56 A B Y S Abyssinia.but afterwards very difficult; being composed of stones raised one above another, the remains, as he conjectures, of a magnificent causeway. As they passed farther on, however, the air was everywhere perfumed by a vast num¬ ber of flowers of different kinds, particularly jessamine. One species of this, named again, was found in such plen¬ ty, that almost all the adjacent hills were covered by it; the whole country had the most beautiful appearance; the weather was exquisitely fine, and the temperature of the air agreeable. In this fine country, however, Mr Bruce had the first opportunity of beholding the horribly barbarous practice of the Abyssinians, in cutting off pieces of flesh from the bodies of living animals, and de¬ vouring them raw; while at the same time they have the utmost horror and religious aversion at pork of every kind; insomuch that Mr Bruce durst not venture to taste the flesh of a wild boar, just after having assisted in the destruction of five or six. During the remaining part of the journey from Adowa to Sire, the country continued equally beautiful, and the variety of flowers and trees greatly augmented; but as a report was propagated that Has Michael had been defeated by Basil, they now met with some insults. These, how¬ ever, were but trifling; and on the 22d in the evening they arrived safely at Sire, situated in Lat. 14. 4. 35. N. This town is still larger than Axum, but the houses are built only of clay covered with thatch; the roofs in the form of cones, which indeed is the shape of all those in Abyssinia. Sire stands on the brink of a very steep and narrow valley, through which the road is almost im¬ passable. It is famous for a manufacture of cotton cloth, which, as already observed, passes as money throughout the whole empire. Beads, needles, antimony, and in¬ cense sometimes pass in the same way. The country in the neighbourhood is extremely fine ; but the inhabitants, from the low situation, are subject to putrid fevers. On leaving it on the 24th, our travellers passed through a Vast plain, where they could discern, as far as the eye could reach, only some few detached hills standing on the plain, covered with high grass, which the inhabitants were then burning. The country to the northward is flat and open. In the way to Gondar, however, lies that ridge of mountains called Samen; of which one named Lamalmon is the most remarkable, and by some supposed to be the highest in Abyssinia. Betwixt Sire and these mountains flows the river Tacazze, which, next to the Nile, is the largest in Abyssinia. Mr Bruce informs us that it car¬ ries near one-third of the water which falls on the whole empire; and when passing it he saw the marks of its stream, the preceding year, 18 feet perpendicular above the bottom; nor could it be ascertained whether this was the highest point to which it had reached. The Tacazze has its source in the district of Angot, rising from three sources, like the Nile, in a flat country, about 200 miles to the S. E. of Gondar. It is extremely pleasant, being shaded with fine lofty trees, the water extremely clear, and the banks adorned with the most fragrant flowers. At the ford where they crossed, this river was fully 200 yards broad, and about three feet deep, running very swiftly over a bottom of pebbles. At the very edge of the water the banks were covered with tamarisks, behind which grew tall and stately trees, that never lose their leaves. It abounds with fish, and is inhabited by croco¬ diles and hippopotami; the former of which frequently carry off people who attempt to cross the river upon blown up skins. The neighbouring woods are full of lions and hyenas. The Tacazze is marked by Mr Bruce in his map as a branch of the Astaboras, which falls into the Nile. The latitude of the ford was found to be 13. 42. 45. N. S I N I A. This river was passed on the 26th of January; after Abyss!) which our travellers entered into the country of Samen the governor of which, Ayto Tesfos, had never acknow¬ ledged the authority of Has Michael, nor any of the em¬ perors set up by him since the death of loas. The coun¬ try therefore was hostile ; but the uncertainty of the event of the war, and the well-known severity of Michael’s dis¬ position, preserved our traveller and his company from any insult, excepting a feeble and unsuccessful attempt to ex¬ tort money. Here Mr Bruce observes that the people were more flat-nosed than any he had hitherto seen in Abyssinia. The path among the mountains was for the most part exceedingly dangerous, having a precipice of vast height close by it which way soever you turn. The mountains appeared of very extraordinary shapes; some like cones; others high and pointed, like columns, pyra¬ mids, or obelisks. In one place a village was observed in so dangerous a situation, that scarce the distance of a yard intervened between the houses and a dreadful pre¬ cipice. The lions and hyenas were very numerous among these mountains, and devoured one of the best mules our travellers had. The hyenas were so bold, that they stalked about as familiarly as dogs, and were not intimidated by the discharge of fire-arms. Their voracity was such, that they ate the bodies of those of their own species which our travellers had killed in their own defence. On the 7th of February the travellers began to ascend Lamalmon by a winding path scarcely two feet broad, on the brink of a dreadful precipice, and frequently intersect¬ ed by the beds of torrents, which produced vast irregular chasms. After ascending two hours with incredible toil up this narrow path, they came to a small plain named Kedus or St Michael, from a church of that name situated there. On ascending to the very top of the mountain, where they arrived on the 9th of February, our travellers were surprised to find, that though from below it had the appearance of being sharp-pointed, it was in reality a large plain full of springs, which are the sources of most of the rivers in this part of Abyssinia. These springs boil out of the earth, sending forth such quantities of water as are sufficient to turn a mill. A perpetual verdure prevails; and it is entirely owing to indolence in the husbandman if he has not three harvests annually. Lamalmon stands on the north-west part of the mountains of Samen; but though higher than the mountains of Tigre, our author is of opinion that it is considerably inferior to those which are situated on the south-east. The plain on the top is N altogether impregnable to an army, both by reason of its situation and the plenty of provisions it affords for the maintenance of its inhabitants; even the streams on the top are full of fish. Here the mercury in the barometer stood at 20^ inches. During the*time our travellers remained at Lamalmon, a servant of Has Michael arrived to conduct them safely to the capital, bringing a certain account of the victory over Fasil; so that now the difficulties and dangers of their journey were over. The country appeared better cultivated as they approached the capital; and they saw several plantations of sugar-canes, which are raised from the seed. In some places, however, particularly in Wog- gora, great damage is done by swarms of ants, rats, and mice, which destroy the fruits of the earth. Mr Bruce had already experienced the mischief arising from a small spe¬ cies of ant, whose bite was not only more painful than the sting of a scorpion, but which issued out of the ground in such numbers as to cut in pieces the carpets and every thing made of soft materials. M lien Mr Bruce approached the capital, he was dress¬ ed like a Moor: and this dress he was advised to keep AB Y S byssinia. until he should receive some protection from government; vr~v''^/his greatest, indeed his only, danger arising from the priests, who were alarmed at hearing of the approach of a Frank to the capital. This was the more necessary, as the emperor and Michael Ras were both out of town. For this reason also he took up his residence in the Moorish quarter of Gondar, a large city, containing not fewer than 3000 houses. The only inconvenience he underwent here, was the not being allowed to eat any flesh : for we have already taken notice of a law made by one of the emperors, that none of his subjects should eat flesh but such as had been killed by Christians ; and a de¬ viation from this would have been accounted equal to a renunciation of Christianity itself. Here he remained till the 15 th of February ; when Ay to Aylo waited upon him, and addressed him in the character of physician, which he had assumed. By this nobleman he was carried to the palace of Koscam, and introduced to the old queen. His advice wras required for one of the royal family who was ill of the small-pox; but a saint had already under¬ taken his cure. The event, however, proved unfortunate; the patient died, and the saint lost his reputation. Our limits will not allow us to give any particular account of the steps by which Mr Bruce arrived at the high degree of reputation which he enjoyed in Abyssinia. In general, his success in the practice of medicine ; his skill in horse¬ manship and the use of fire-arms, which by his own ac¬ count must have been very extraordinary; his prudence in evading religious disputes; as well as his personal in¬ trepidity and presence of mind, which never once failed him, even in the greatest emergencies; all conspired to render him agreeable to persons of every denomination. By the king he was promoted to the government of Ras- el-Feel, was his constant attendant on all occasions, and was with him in several military expeditions; but never met with any opportunity of distinguishing his personal valour, though he had the command of a body of horse at one of the battles fought at a place named Serbraxos. Thus honoured and employed, he had an ample oppor¬ tunity of exploring the sources and cataracts of the Bahr- el-Azrek, which he considered the Nile, as well as the geography and natural products of the whole country ; ob¬ taining also leave at last to return home. Ihe truth and accuracy of Mr Bruce’s narrative have excited greater controversy than has arisen in regard to any other work of the same description. No book ever passed through a severer ordeal; and some have not even scrupled to represent it as a mass of fiction from beginning to end. Such an opinion is now on all hands admitted to be unfounded. There certainly do appear to be some pas¬ sages that are highly coloured; nor are there wanting a few adventurous sallies, that seem to have but little foun¬ dation in reality. But it is no longer doubted that the events of his journey, and his account of the country and people, are in the main correct. Mr Salt, though he pointedly exposed the mistakes and exa£>Serations of Mr Bruce, yet bears ample and willing testimony to the general accuracy of his descriptions and narrative; and records, in more than one instance, the astonishment which the Abyssinians expressed at the knowledge which Mr Bruce displayed of their history and country. Mr Browne and Mr Antes, who had excellent oppoi tunities of comparing Mr Bruce’s statements with 11e accounts given by persons well acquainted with , yssmia, bear testimony to the general accuracy of his etai s; and Dr C larke, while at Cairo, obtained from an Abyssinian Dean, whom he met there, direct and specific 'evidence in favour of the correctness of some parts of his narrative, which had till then been regarded w ith suspicion. VOL. ii. r S I N I A. 57 The plates given in Mr Bruce’s Travels, especially those of Abyssinia, natural history, were early represented as inaccurate: and^v^-' that they may be so in some of the minutiae is not improbable, as Bruce laid no claim to a scientific knowledge of the sub¬ ject; but when Dr Clarke showed these plates to the Abyssinian Dean, though he knew not the nature of the book in which they w'ere contained, and the name of Bruce was not mentioned, the latter immediately gave the same appellations, and assigned the same uses as Bruce, to the Ergett-denimo, Eyett el krone, Emsett, Kolquall, Gergir, Kantuffa, &c. He confirmed the account of the zimb fly, and asserted that he had heard of armies being destroyed by it. When Bruce’s map was laid before him, though of course he could not read the names, he pointed out the locality of Gondar, exactly where Bruce had placed it. A considerable period elapsed between the date of Mr Bruce’s travels, and those of Mr Salt, the next European traveller in Abyssinia; and Mr Browne informs us, that, for nine years preceding 1796, there was even no com¬ munication between Egypt and that country, probably in consequence of the unsettled state of Sennaar and Nubia. Mr Salt’s first journey into Abyssinia took place in the Mr Saifs year 1805. Having accompanied Lord Valentia in hisjourneys. travels in the East, and his Lordship being desirous of ascertaining the state of Abyssinia, and the probability of opening a commercial intercourse between it and Bri¬ tain, and her oriental dominions, Mr Salt undertook the conveyance of some presents from his Lordship to the Ras. An abstract of the most important information con¬ tained in both his journeys will afterwards be given; at present we shall confine ourselves to a brief outline of his route. From Massowa he proceeded to Arkeeko; and thence southwards, with a little inclination to the west, he passed over Taranta to Dixan. On leaving this place, he proceeded to Antalo, through Abha, Agowma, and Chelicut. At Antalo he found the Ras, and deliver¬ ed Lord Valentia’s presents. From Antalo he made an excursion to Axum, by the route of Mucullah and Adowa, at which latter place he met with Fasilydas, the son of Yasous, formerly king of Abyssinia. At Axum he par¬ ticularly examined the obelisks, inscriptions, and ruins; he also discovered a Greek inscription fifteen hundred years old, which proves Axum to have been the capital of a people called the Axumites, and gives credibility to the accounts before doubted, of embassies sent to them by the Romans. This inscription fixes the conquest of part of Arabia by the Abyssinians at an earlier period than w'as hitherto supposed. From Axum Mr Salt returned to Antalo by the road he came ; and on his leaving the coun¬ try, he again visited Axum and Dixan. Mr Pearce, one of his attendants, was left behind at Antalo; and when Mr Salt arrived in Abyssinia the second time, about five years afterwards, he learned from Mr Pearce, that during his residence in that country he had made an attempt to reach Gondar. For this purpose he set out from Antalo, and directed his course through the province of Wojjerat, a plain inhabited by negroes called Doha, and a district of the Galla tribe. Soon after¬ wards he reached the town of Mocurra, and the village of Dufat on one of the high Lasta mountains ; his course dur¬ ing the whole of this part of his journey being nearly south. After passing the village of Dufat he arrived at the town of Senare, and visited the sources of the river Tacazze, having before this met with no stream of importance. He now changed his route, following the course of the river, nearly due north, and afterwards north-east to Socota, the reputed capital of Lasta, the district which, before his de¬ parture from Antalo, he was advised to pass through, as lying in the most accessible road to Gondar. From Socota H 58 ABYSSINIA. Abyssinia, he proceeded northwards along the banks of the Tacazze, 'and, having crossed it, entered the province of Samen, the mountains of which he ascended till he reached Mishekka, and afterwards descended them to Inchetkaab, where Ras Gabriel resided. Here having learned that Ras Welud Se- lasse, with whom he had been left by Mr Salt at Antalo, was in danger of being attacked by the Galla, he return¬ ed to that town by a more direct route than he pursued in his journey to Inchetkaab. His next excursion was, in company with the Ras, against his enemies, through Lasta; and, the Galla having been defeated, he went into the plains of the Edjow. Next year, engaging again in the campaign, he accompanied the army into Hamazen. He also passed over the salt-plain by Amphila. These were the principal parts of Abyssinia which Mr Pearce had an opportunity of visiting, during the interval between Mr Salt’s departure from and return to that country. Mr Salt, in his second journey, proceeded from the coast of the Red Sea, by the route of Weah, to the foot of the Taranta mountains, which he crossed to Dixan, and thence proceeded to Chelicut. Here he ascertained that it was impracticable to accomplish the immediate object of his journey, the personal delivery of the presents with which he had been intrusted by his Majesty to the em¬ peror of Abyssinia; as that monarch lived entirely neglect¬ ed, and in fact a prisoner at Gondar, which was in the possession of Guxo, a chief of the Galla, and the decid¬ ed opponent of Mr Salt’s friend, Ras Welud Selasse. Dis¬ appointed in this object, he made’an excursion to the Ta¬ cazze, through the province of Avergale, a distance of sixty miles west from Chelicut; and on his return to the latter town, he made another excursion to Antalo. On finally quitting Chelicut, he passed through the high dis¬ trict of Giralta, whence he descended the steep pass of Atbara, to the banks of the Warre. His route was next to Adowa, over several ridges of hills. From Adowa he made an excursion to Axum, for the purpose of re-exa¬ mining its ruins and inscriptions. Having accomplished this object, he returned to Adowa, and thence to the sea- coast. From this brief outline of Mr Salt’s two journeys, and of the excursions of Mr Pearce, it will appear that neither of them penetrated so far into Abyssinia as Mr Bruce had done; nevertheless, their narratives are of very consider¬ able value, not only on account of the new information which they supply, but also as they enable us to place more steady confidence in such parts of Mr Bruce’s state¬ ments regarding Abyssinia as they had the opportunity of verifying; and to ascribe to his Travels their just de¬ gree of value and accuracy. The voyage of Hemprich, Ehrenberg, and their compa¬ nions, of which we have as yet only a rapid sketch from the pen of M. Humboldt, does not promise to throw much light on the civil and interior state of Abyssinia. It appears that they never passed the barrier chain of mountains, but merely explored that north-eastern face which looks to the Red Sea. Their researches and collections relative to the natural history of this region, as well as of Nubia, and the others to which their journey extended, appear to have been very extensive ; but the details have not yet been communicated to the public. It will now be our object to draw, from the narratives . . of Mr Bruce and Mr Salt, a connected view of the statis- Abyssmia. tjc^ an(j tpe c—j an(j gociai con(liti0n of this remark¬ able country. When Mr Salt was last in Abyssinia, it was divided into three distinct and independent states. Tigre, which was the most powerful, was under the dominion of Ras Welud Selasse, who possessed the monopoly of all the muskets Present state of imported, and of all the salt. Tigre comprehends about Abyssin four degrees of latitude, and the same of longitude; it possesses the sea-coast, is naturally strong, and is inhabit¬ ed by a warlike people. Its divisions are, 1. Tigre pro¬ per ; the general character of which is, a range of hills, in¬ tersected by deep gullies and cultivated plains. 2. Agame, which lies to the east of Tigre proper. This division, being level land, at a considerable height above the sea, and consequently enjoying a favourable climate, is rich and fertile. On its eastern frontier, and near the Taltal, it is strong; the salt-plain is in its vicinity. 3. The di¬ vision of Enderta, to the south of Agame, is mostly moun¬ tainous ; its capital is Antalo, in which the Ras resides, on account of its being situated so as to protect the southern provinces from the Galla. 4. To the south of Enderta ia the division of Wojjerat; a wild district, full of forests, in which the lion, elephant, and rhinoceros are found. 5. . Adjoining to Wojjerat, is the small and low division of Wofila, which borders on the lake Ashangel. Here the Galla are intermixed with the native Abyssinians, and pro¬ fess the Christian religion. 6. The division of Lasta is rug¬ ged, and almost entirely composed of inaccessible moun¬ tains. To the north of this there are two mountainous districts ; and between them and the Tacazze are two low districts, inhabited by Christian Agows. 7. Farther to the north lies the division of Avergale. It is very narrow, and stretches, for about fifty miles north and south, along the Tacazze. It is inhabited by the Agows. 8. The division of Samen, which is to the east of the Tacazze, is the highest land in Abyssinia. Its mountains run north and south, about eighty miles. 9. Between the northern border of Samen and Tigre proper lies the valuable dis¬ trict of Zemben. 10. Above Zemben, to the west of Axum, is the division of Shire, the most picturesque part of Abyssinia, abounding in rich valleys, flowery meadows, and shady groves. 11. The last division of Tigre is com¬ monly called the kingdom of the Baharnegash. The second independent state is that which still retains the name of Amhara. This is almost entirely in the pos¬ session of the Galla, whose chief is Guxo, the enemy of Ras Welud Selasse. His power on the west side of the Tacazze is absolute; and it is much strengthened and in¬ creased by his connection with the southern Galla. His cavalry are estimated at twenty thousand, chiefly from the district of Begemder. Gondar belongs to him. The third grand division, which lies in the south of Abyssinia, is now entirely separated from the two others by the Galla : it consists of the united provinces of Shoa and Efat, which are supposed to retain a larger portion of Ethiopian literature and manners than any other part of Abyssinia. Efat lies between the ninth and eleventh de¬ grees of north latitude. It is principally high land, running north and south, and gradually declining on each side into a plain country. Streams flow from both sides of the moun¬ tains, and fall into the Nile and Hawush. Two branches of the latter nearly encircle this province. The present ruler is the grandson of Yasous, mentioned by Bruce (but, as Dofter Esther informed Mr Salt, incorrectly) as having visited Gondar while he was there. He resides at Anko- ber, the capital of Efat. This district is one of the finest in Abyssinia, and in power equal to that of Ras Welud Se¬ lasse. Its force is chiefly cavalry, who are very skilful and courageous. The province of Shoa lies on a lower level than that of Efat; there is extremely rich pasturage in its valleys ; it contains several large towns, and many monasteries. The district of Walaka and Gondar are de* pendent on the united provinces of Shoa and Efat. Of the rivers, the Tacazze rises from three small springs in the plains of Margilla; it is joined by the river Arequa, ABYSSINIA. 59 . which runs through the province of Avergale, in a north¬ west direction, in the district of Zemben ; and it forms one of the larger branches of the Nile. The Bahr-el-Azrek, or Blue River, or Azergue, the chief Abyssinian branch of the Nile, rises from two fountains in Sacala, near Geesh, flows through the lake of Dembea, sweeps, after quitting the lake, in a semicircular direction round the provinces of Damot and Gojam, and unites with the Bahr-el-Abiad, or White River, at Wed Hogela, in latitude 16. N. This river, the real Nile, is supposed to rise in the Jibbel- el-Kumri, or mountains of the Moon. The other rivers are, the Maleg, which joins the Abyssinian Nile, after a parallel course, on the west; the Mareb, which forms the boundary between Tigre and the kingdom of the Baharne- gash ; the Hanazo and Hawush, which flow in an opposite direction, towards the entrance of the Red Sea; and the Jemma. The principal lakes are, Dembea, or Tzana, about sixty miles long, and thirty broad, where most extensive, and in the wet seasons; the lake of Lawasa, in the south¬ ern extremity of Abyssinia, a chief source of the Hawush ; the lake of Haik, near the rocks of Geshen and Ambazel; and the Ashangel. The great difference of climate, owing to the vast ex¬ tent and variety of elevation in different parts of this em¬ pire, is very perceptible in its soil and productions. The mountains in many places are not only barren, but alto¬ gether inaccessible, except by those who make it their constant practice to climb amongst them; and even by them they cannot be ascended without great difficulty and danger. The shapes of these mountains, as we have al¬ ready had occasion to observe, are very strange and fan¬ tastical ; exceedingly different from those of Europe : some resembling towers and steeples, while others are like a board or slate set up on end ; the base being so narrow, and the whole mountain so high and thin, that it seems wonderful how it can stand. In the valleys, however, and flat parts of the country, the soil is excessively fruitful,, though in the warmest places grain cannot be brought to perfection. Wine is also made only in one or two places; hut the greatest profusion of fruits of all kinds is to be met with everywhere, as well as many vegetables not to be found in other countries. There is a vast variety of flowers, which adorn the banks of the rivers in such a manner as to make them resemble fine gardens. Among these a species of rose is met with, which grows upon trees, and is much superior in fragrance to those which grow on bushes. Senna, cardamom, ginger, and cotton, are likewise produced here in great quantities. Among the rare plants to be met with in Abyssinia, Mr Bruce particularly describes the following:—1. The papyrus, the ancient material for paper; which our au¬ thor supposes to have been a native of Ethiopia, and not of Egypt, as has been supposed. 2. Balessan, balm, or balsam plant; a tree growing to the height of 14 or 15 feet, and used for fuel along with other trees in the coun- try- It grows on the coast of the Red Sea, among the myrrh trees behind Azab, all the way to Babelmandel. Dus is the tree producing the balm of Gilead mentioned in Scripture. 3. The sassa, myrrh, and opocalpasum trees. These grow likewise along the coast of the Red Sea. The sassa or opocalpasum is used in manufactures; and, ac¬ cording to our author, resembles gum adragant, probably tragacanth. The tree which produces it grows to a great size, and has a beautiful flower, scarce admitting of descrip¬ tion without a drawing. 4. Ensete, an herbaceous plant, growing in Narea, in swampy places; but it is supposed to grow equally well in any other part of the empire, where there is heat and moisture sufficient. It forms a great part of the vegetable food of the Abyssinians. It produces a kind of figs, but these are not eatable. When Abyssinia, used for food, it is to be cut immediately above the small detached roots, or perhaps a foot or two higher, according to the age of the plant. The green is to be stripped from the upper part till it becomes w'hite; and when soft, it affords an excellent food when eaten with milk or butter. 5. Rack is a large tree, growing not only in Abyssinia, but in many places of Arabia Felix. Its wood is so hard and bitter, that no worm will touch it; for which reason it is used by the Arabs for constructing their boats. It grows, like the mangrove, among the salt water of the sea, or about salt springs. 6. Cusso, or Banksia anthelmintica, is a very beautiful and useful tree, being a strong anthelmin¬ tic, and used as such by the Abyssinians. 7. Teff is a kind of grain sown generally throughout Abyssinia, and constituting the bread commonly made use of by the in¬ habitants. They have indeed plenty of wheat, and are as skilful in forming it into bread as the Europeans; but this is only made use of by people of the first rank: however, the teff is sometimes of such an excellent quality, that the bread made from it is held in equal estimation with the finest wheat. From the bread made of this grain a sourish liquor called bouza is prepared, which is used for common drink like our small beer. A liquor of the same kind, but of inferior quality, is made from barley cakes. Some have been of opinion that the use of teff occasions worms; but this is controverted by Mr Bruce. 8. Nook, a plant not to be distinguished from our marigold, either in shape, size, or foliage, is also sown very generally over the country, and furnishes all Abyssinia with oil for the kitchen and other uses. Our knowledge in this department is considerably in¬ creased by Dr Murray’s edition of Bruce, and Mr Salt’s two journeys. The lehem, or Toberne montana, a tree common near the lake of Dembea, is remarkable for its beauty and fragrance ; it grows to a considerable size, the extremities of its branches trailing along the ground, laden with flowers from top to bottom in great profusion, each cluster con¬ taining between eighty-five and ninety, open or shut; the fruit is eaten, but has rather a harsh taste. The anguah, found near the Tacazze, produces a gum resembling frank¬ incense. The leaves of the geesh, which is very common, are put by the Abyssinians into their maize; they are likewise reduced to powder, and mixed with the other ma¬ terials of which they make sown. The mergombey, a spe¬ cies of Solarium, is used as a cathartic ; and from the niche, or niege, they extract their vegetable oil: it is a species of Sesanum. These are the principal plants, descriptions and plates of which are given from Mr Bruce’s manuscripts and drawings, by Dr Murray. Mr Salt’s researches have added eight new genera, and one hundred and twenty- four new species, to botany. Near Shela, a species of narrow-leaved Ficus grows, called by the natives chekunit; the inner rind of the bark of which, having been bruised on a stone, twisted round a stick, and dried, is used as matches for their fire-arms. Near Adowa, Mr Salt found a new and beautiful species of Amaryllis, bearing ten or twelve spikes of bloom on each stem, from one receptacle, as large as those of the belladonna. The corolla is white; each petal is marked down the middle with a single streak of bright purple ; it is sweet-scented, like the lily of the valley; the bulbs are frequently two feet under ground. Mr Salt brought this plant to England. The domesticated animals are oxen. The Galla oxen, or sanga, were not seen by Mr Bruce; and his account of them is not strictly correct, their large horns not being the effect of disease. The largest Mr Salt ever saw was four feet in length, and the circumference at the base twenty-one inches. The horns of one of them are in the 60 AB Y S Abyssinia, museum of the College of Surgeons in London. The ani- mal itself is of the usual size, and of various colours ; it is by no means common in Abyssinia, being brought only by the cqfilas, or salt caravans, as a valuable present, from the south. The sheep are small and black ; the horses strong and beautiful. Besides these, there are mules, asses, a few camels, and two species of dogs ; one of which owns no master, but lives in packs in the villages, like the paria dog in India; the other is kept for game, especially for Guinea fowls, which it catches very expertly. The wild animals are, the elephant, which is hunted by the Shangalla for their teeth : the cawe leopard, only found in the interior districts ; very shy; its skin is an article of barter : the two-horned rhinoceros, only found in the forests of Wojjerat, and the low land near the Funge; its horns have no connection with the bone of the head, consequently the opinion of Sparman, that they can raise and depress them at pleasure, may be cor¬ rect. This rhinoceros has no folds in the skin, as the one-horned has; its skin is used for shields ; its horns for handles to swords and daggers, and, according to the Abyssinian Dean whom Dr Clarke interrogated at Cairo, as a lining to drinking vessels, being regarded as an anti¬ dote to poison. The foremost horn is two feet long, and very large in other respects. The buffalo is very com¬ mon in the forests of Ras-el-fil; shields are made from its skin with great art. The zebra, in the south chiefly ; its mane decorates the collars of the war-horses belonging to chiefs of great rank on days of state. The wild ass is found in some parts; lions occasionally, especially in the sandy districts near the Tacazze. Whoever kills one wears the paw on his shield : the skin, richly ornamented, forms a dress like that worn by the Caffre chiefs. There are several species of leopard, one black, extremely rare, the skin of which is worn only by governors of provinces. The lion-cat, tiger-cat, or grey lynx, and wild-cat, are not uncommon. From the libet, civet is procured, and is an article of commerce. The hyena: Mr Salt remarks that it has a singular cry—three distinct deep-toned cries ; then silence for a few minutes, succeeded by the same kind of cry. The hyena and dog seldom fight; they even feed on the same carcass. A small kind of wolf; common fox; sea fox; and jackal. There is a great variety of antelopes, one of which is probably allied to the chamois,' being confined to the cold and mountainous district of Samen. Several species of monkey ; the wild boar ; por¬ cupine ; cavy, nearly allied to that of the Cape ; a small grey hare, deemed by the natives unclean ; squirrel; rats, very numerous in the fields; an undescribed species of lemur, the size of a cat, with a long tail, faintly striped with black and white, with white bushy hair at the end : the hair on the body is long, and of a clear white, except on the back, where there is a large oval spot covered with short deep-black hair. Of this every man in Tigre en¬ deavours, if possible, to have a piece on his shield. The hippopotami are chiefly found in the deep pits, like lochs, between the fords of the Tacazze ; they roll and snort like a porpus; they cannot remain longer than five or six minutes under water; their colour is a dusky brown, like the elephant; their usual length sixteen feet. Whips are made of their skin, and used to brush away the flies, which are very troublesome in hot weather : the butt-ends of the whips are ornamented with hair from the tail of the camelopard. The number of birds in this country is immense. Great numbers of eagles, vultures, hawks, and others of that kind, are met with, and come punctually every year after the tropical rains have ceased. They feed at first upon the shell-fish, which are met with in great quantities on S IN I A. the edges of the deserts, where they had lived in the salt Abyssi springs, but being forced from their natural habitations's-^v' when these springs were swollen by the rains, are after¬ wards left to perish on dry land. When these fail, their next resource is from the carcasses of the large animals, such as the elephant and rhinoceros, which are killed in the flat country by the hunters. Their next supply is afforded by the multitude of rats and field-mice which infesi the country after harvest. The vast slaughter of cattle made by the Abyssinian armies, the multitude of persons killed, whose bodies are allowed to rot on the field of battle, &c. furnish them also with another resource. These supplies, how¬ ever, all fail at the beginning of the rainy season, when the hunters and armies return home, and the vast quantity of water which continually overflows the ground renders it impossible for them to find any other food. The rarest birds brought home by Mr Salt from Abys¬ sinia are, a new species of JBttcco, since called JB. Saltii, which clings like the woodpecker to the branches of trees: a variety of the Upupa erythrorhynchos, with a black tail; it feeds on the figs of the Ficus sycamorus : a non-descript species of Merops; a non-descript species of Tanapq, which perches on the backs of the cattle, and feeds on the grubs which infest them in hot weather; the Columba Abys- sinica, wild among the daro trees, eaten by the Abyssi- nians ; the Tringa Senegalla ; the Erodia a?nphilorsis, al¬ lied in some degree to the Arodea Pondiceriana, probably a new genus ; the Cursorius Europceus, an extremely rare bird, shot on the sandy plains near the Tacazze. Bees are domesticated in the province of "Wojjerat, which is famous for white honey, sold at Antalo. Mr Salt gives a dreadful account of the ravages of the Abys* sinian locust. Little is known respecting the mineralogy of Abys¬ sinia. Near Weah there are low hills of granitic rocks, resting on a bed of micaceous earth. In the district of Tigre the soil is sandy; the rocks, composed of slate, schistus, and granite, lie in perpendicular strata. In the districts of Geralta and Enderta the strata are rather horizontal. But the salt-plain is the most interesting, not only in a mineralogical, but also in an economical view, as from it the Abyssinians obtain the pieces of salt which they use as money. This plain lies near the coun¬ try of the Assa Durwa, about fifty miles west of Amphila, on the road to Massowa ; it is about four days’ journey in extent from north-east to south-west, and is crossed in sandals made of the leaves of a species of palm. The plain is perfectly flat; for the first half-mile the salt is soft; it then becomes hard and crystallized, like ice on which snow has fallen after it has been partially thawed: branches of pure salt occasionally rise above the surface. It is cut with an adze into pieces the shape of a whet¬ stone. For about two feet immediately under the sur¬ face it is hard and pure ; afterwards it is coarse and soft¬ er, till exposed to the air. The employment of cutting the salt is very dangerous, on account of the Galla, who frequently attack the workmen : none, therefore, are em¬ ployed except the lowest order of the natives, who lie down on their backs, or flee to the mountains, on the ap¬ proach of the Galla. Salt caravans, called cafilas, are regularly sent for salt from Antalo; and the situation of Balgudda, or protector of these caravans, is of great im¬ portance as well as emolument; for on their safe arrival mainly depends the internal and external commerce of the Abyssinians: when they arrive, therefore, they are received with great acclamation and joy. The Galla fre¬ quently attack them. The pay of the Balgudda is derived from the duty imposed on the importation of salt;—-a camel, the usual load of which is two hundred pieces, I i ysainia. pays eleven; a mule, carrying eighty, pays nine ; an ass I ^ pays six. With respect to the climate, Mr Salt found that the thermometer, in March, April, and May, averaged 70° at Chelicut, 65° at Antalo, 95° on the banks of the Tacazze, and on the mountains of Samen he supposed it to be be¬ low the freezing point. He contradicts, from his own ob¬ servation, Mr Bruce’s statement, that snow is not known in Abyssinia. The Samen mountains were covered with snow at the time Mr Salt saw them; and Mr Pearce, in his passage over them, experienced a heavy fall. Ijricul- Two varieties of1 wheat are cultivated, of which they tu;- make large loaves, either baked or prepared by steam. These, however, are used only at the tables of the great. The teff, which is their usual food, varies in colour from white to black. The Abyssinian Dean informed Dr Clarke that beer, or sowa, was made from selleh, and not from teff; and that it is not made from the latter, is con¬ firmed by the testimony of Michael, Mr Bruce's servant. (Murray’s Life of Bruce, 4to. p. 252.) The neug, which is like the raggy of India, is next in esteem to the teff, with which, or with barley, it is mixed to make bread. It is harsh and dry. Two kinds of barley are sown; the black in great quantity, but it is only given to horses and mules. Maize is much cultivated between Galla and Dixan, but not made into bread. The vetch is cultivated for the purpose of mixing it with teff, or forming it with ghee and curds into balls. It is eaten in the morning. The worst grain of every kind is generally used for seed. As almost every man cultivates enough for his family, it is seldom sold. On the low lands there are two crops. The ploughs are rudely made, from the root or branch of a tree ; sometimes the shares are of iron. They are drawn by oxen. The land is twice ploughed, afterwards the clods are broken by women; and when the corn is half ripe, it is weeded by men, women, and children, singing as they work: only females reap, and when strangers pass they utter a sharp shrill cry, the Liralect of Syria, where it is used on the same occasion. It is produced by trilling the tongue against the roof of the mouth, without any dis¬ tinct words, but a constant repetition of the syllable al, uttered with the utmost rapidity. In some parts the grain, when carried, is secured from the weather by means of tanned kid-skins. The plain of Larai> near Dixan, re¬ sembles the vale of Evesham. It is highly cultivated, and irrigation is practised in it. Cotton is grown near the Tacazze, and sold at Adowa. pltoms, Mr Saifs description of a brind feast, though not so I r highly coloured as that of Mr Bruce, is still sufficient to prove the barbarism of the Abyssinians. The sides of the table are covered with piles of thin cakes made of teff, reach¬ ing to the height of a foot, and two feet and a half in dia¬ meter ; in the middle a row of curry dishes is placed. Near f the lias there are a number of fine wheaten rolls, for his own use, and that of his favourites. The signal to begin the feast is given by his breaking and distributing them : im¬ mediately female slaves, having washed their hands, dip the tell into the curry, and serve it to all the guests, ex¬ cept the Has, who receives his portion from a male slave, and afterwards distributes it among the chiefs, who ac¬ knowledge the favour by standing up and bowing. Balls composed of teff, greens, and curds, are next handed about. In the mean time the process of killing the cattle proceeds in the adjoining yard. That process is simple:— the beast is thrown on the ground, and its head separated from the body with a Jambea knife, during which an invoca¬ tion is always pronounced. The skin is immediately stript oh one side, and the entrails being taken out, are devour¬ ed by the attendants. While the fibres are yet quivering, the flesh is cut into large pieces. These are of no regu- Abyssinia- lar size; but generally a piece of bone is attached to the^-^v^-' flesh, by which it is brought into the dining-room. The chiefs with their crooked knives cut off large steaks, which they divide into long stripes, half an inch in diametey. If they are not pleased with the piece they haye got, they hand it to a dependant, who, in his turn, if not pleased, hands it to another, till it comes to one whose taste or rank does not induce or authorize him to reject it. As soon as the first party is satisfied, they rise from the table and give way to others. The last cakes are scrambled for with a great noise. It appears from Mr Salt, that though the chiefs sometimes feed themselves at these feasts, yet more frequently, as Mr Bruce relates, they feed one another. Mr Pearce witnessed a live meal, when travelling with the Lasta soldiers. Plaving fasted long, one of them pro¬ posed to cut out the shulada: a cow was throwjn down, and two pieces of flesh, weighing about a pound, cut from the buttock, which they called the shulada. Whenever Mr Salt mentioned the term, he was always understood. After the pieces were cut out, the wounds were sewed up, and plastered over with cow-dung. The animal was driven on, but killed at the end of the journey. The Abyssinians are very expert in dissecting a cow, as there are always a number of applicants, each of whom claims a right to a particular portion. The Abyssinians are very fond of pictures. Their churches are full of them ; and such chiefs as can afford it ornament their principal rooms with them. They paint their pictures on the surface of the walls, tracing the out¬ line with charcoal; they afterwards go over it with coarse Indian ink; and lastly, introduce the colours, which are excessively gaudy. They exaggerate the size of the eye, and paint all classes with full faces, except the Jews, whom they uniformly paint with side faces. On their journeys they sing extemporary verses, one person alone composing and singing them at first, after which they are repeated in chorus by the rest. Their dress consists of a large folding mantle, and close drawers. To these the priests add a vest of white linen next the skin. On their head they wear a small shawl of white cotton, with the crown exposed. Their houses are of a conic form, covered with thatch. In Dixan the houses are flat-roofed, without windows : instead of chim¬ neys, there are pots of earthen ware on the roofs. There are also caves near this place used as dwellings, which are expeditiously made, in a very simple manner—the earth being dug out, and the mortar tempered occasionally with the blade-bone of an ox, and the stones that are used shaped with an adze. Their principal liquor is called maize, made of honey fermented with barley, and strengthened with the root of the Rhamnus inebrians, called sadoo. The liquor is drunk out of Venetian decanters, called brulhes. But the com¬ mon drink among the lower class is made of the bread left at their feasts, and parched barley ; it is called sowa, and is drunk out of horns. Marriage is generally a civil contract. The female, who is seldom consulted on the occasion, is carried to the house of her husband on his shoulders, or those of his friends. The bride and bridegroom are sometimes seated on a throne of turf, shaded with boughs, round which the relations, &c. dance. The dowry consists of gold, cattle, muskets, and cloth, and is always kept apart, and return¬ ed in case of separation. Marriage by civil contract can be dissolved at pleasure ; by religious contract it is more sacred, especially when the parties take the sacrament after marriage. Ladies of rank retain their estates ancl ABYSSINIA. 62 Abyssinia, maiden names, and assume great superiority over their husbands. At Dixan they allow the nails on their left hand to grow to a great length, and cover them with cases of leather to preserve them. In some parts it is not uncommon for one man to have several wives ; only one, however, is deemed his lawful wife: each has her sepa¬ rate residence. When a person is seized with a species of fever called Tigre-ter, his relations show him all the gold and silver ornaments, fine clothes, &c. which they can collect, mak¬ ing, at the same time, a dreadful noise with drums and other musical instruments, to drive the devil out; for they believe all diseases come from the devil. When death is at hand, the drums, &c. cease ; and when it ac¬ tually takes place, howling and tearing the hair and skin from the temples ensue. No time is lost in washing the body and fumigating it with incense, after which it is sewed up in the clothes of the deceased, and buried in great haste. Wben the burial is over, the toscar or feast of the dead commences; an image of the deceased, in rich garments, on his favourite mule, is carried through the town, accompanied by other mules, &c. in gay ap¬ parel, and by female hired mourners, crying out, as in Ireland, “ Why did you leave us ? had you not houses and land ?” When the procession returns, cattle are killed, and an immense number of people feasted: a repetition of this feast, at certain intervals, is given by the different relations of the deceased, who vie with one another in profusion and splendour. When a person is murdered, the criminal is generally given up to the relations of the deceased, who take him to the market-place, and dispatch him with their knives and spears, every relation and friend making a point of striking a blow. When a person accused of any crime is apprehended, he is tied by his garments to another; and it is always considered a sure proof of guilt, if he runs away and leaves his garments behind. The Ras decides disputes ; before him each party makes his statement, and stakes a quantity of salt, a mule, slaves, gold, &c. on the veracity of his statement; the party convicted is punished by the forfeiture to the Ras of what he staked. Lands descend from father to son; when there is no son, they go to the brother. All the children and relations have a claim on the property of the deceased; if he has neither, he generally directs it to be sold, and one half to be given to the priests, and the other to the poor. Their Lent continues fifty-two days, during which they never taste food till after sunset. The chief amusement on the holydays after Lent, among the lower classes, very much resembles the English game of bcmdy. On the feast of Epiphany, which, according to the Abys- sinians, is the 11th of January, they assemble, in com¬ memoration of our Saviour’s baptism, near brooks, into which they jump, after having received the blessing of the priest, leaping, dancing, ducking one another, and shout¬ ing. In the performance of baptism three priests are en¬ gaged ; one Avith the incense, another with a golden cross, and the third with the consecrated oil from the patriarch of Alexandria. The person to be baptized is first washed over with water, and afterwards crossed on the forehead with some of that element, over which the incense has been waved, and into which the consecrated oil has been dropped. When the person is a Mahometan, every joint and limb is crossed with the consecrated oil; he is then wrapped in a white linen cloth, and partakes of the sacra¬ ment. No unbaptized person is allowed to enter a church. The sacrament is given in both kinds, with new leavened bread, and wine made of a red grape common in some parts of the country. Great numbers of pilgrims, in a yel¬ low dress, with cords round their waists, resort to theAbyssk rich and beautiful plains of Walasse, where they spend their time, by no means innocently, amidst its retired groves. The Christians near Dixan are distinguished by a cross on their breast, arm, &c. and a blue silk string round their neck. They say prayers over whatever they eat, drink, receive, or give, and afterwards blow on it, turning their heads to the east. They turn the heads of animals to the west when they kill them. A striking resemblance may be traced between some of the superstitions of the Abys- sinians and those which still linger in our own country. The falcon, called goodie-goodie, is never killed by them; and when an Abyssinian sets out on a journey and meets one, he watches it carefully; if it sit still, with its breast towards him till he is past, he regards it as a good omen; if its back is towards him, it is unpropitious; and if it fly away, no motive will induce him to proceed on his journey. It is a prevalent belief, that every worker in iron transforms himself, at night, into an hyena, and preys on human flesh ; but if, while thus transformed, he is wounded, the wound remains in the corresponding part of his own body. The languages spoken in Abyssinia and the neighbour¬ ing districts are, a corruption of the Geez, called Tigre, Amharic, Falasha, Gafat, Agow, Tcheretch Agow, Shan- galla, and Galla. According to Dr Murray, the written Geez is the oldest dialect of the Arabic in existence. The Amharic, the modern language of Abyssinia, is likewise an Arabic dialect, more simple than the Geez in the form of its verbs, but in all other respects the same. The Falasha is spoken by the tribes professing the Jewish re¬ ligion, who formerly ruled in Dembea, Samen, and near the Angrab and Kahha ; it is one of the ancient Ethiopian tongues, and has no affinity to the Arabic or Hebrew. The language of the Gafat nation is a corrupted dialect of the Amharic. Respecting the tribes which border upon, or are inter¬ mixed with, the Abyssinians, Mr Salt has supplied us with some additional information. The Jews are very numerous in Gondar and the pro¬ vinces of Samen and Kuara; they are chiefly employed in building and thatching houses. The Hazorta tribe inhabit the mountains near Tubbo, and command the only practicable passage into Abyssinia. They are a brave and rude people. Their population is about 5000, over whom there are five chiefs. They pos¬ sess many cattle, which they seldom kill, but barter with the Abyssinians for grain, being almost entirely ignorant of the art of raising corn. They assist the Abyssinians in getting in their harvests. During the rainy season they go to the sea-side for three, four, or five months, and on their return bring salt, which they exchange for grain with the Abyssinians. When they beat their tom-toms, they clap their hands, and hiss in such a manner, that the sound resembles the quick alternate pronunciation of the letters p t s. Only one person dances at a time, generally a chief; his feet move little, but his body, and particularly his shoulders, is extremely agitated with a kind of writh¬ ing gesture. The name Shangalla (or, according to Bruce, Shankala) is applied by the Abyssinians to the whole race of ne¬ groes. One tribe of them were represented to Mr Salt as living three days’ journey beyond the Nile, and as having a very imperfect notion of any supreme being. The only species of adoration which they exhibit occurs during a great holyday, when all the people assemble and kill a cow, by stabbing it in a thousand places. They have no priests or rulers, but pay respect to old age; the ABYSSINIA. 63 j yssinia. old men being allowed to drink first, and take two wives. In their marriages they mutually take each other’s sisters. If one of the parties has no sister, he gives one of his female slaves. The women assist the men in ploughing, &c. and have an equal share of the produce of the land. These people are named from some circumstances relating to their birth, as “ Born in the nightor “ Born while making boozaor from some marks on their bodies. They are buried in their clothes, without ceremony, the relatives feasting on the cattle of the deceased, his wife getting the household furniture, and the sons his arms, land, and agricultural implements. When hunting, they eat whatever they can procure, even an elephant or a rat. They tie the legs of their prisoners, and employ them in making cloth, or manufacturing iron. Those who cannot work, they kill. The Abyssinians consider it as sport to hunt the Shangalla. There are at least twenty tribes of the Galla, some of whom, entering Abyssinia from the south, have become naturalized, and adopted the manners of the Abyssinians. The tribes out of Abyssinia have little connection with one another, though they speak the same language; each has its own chief, and they are often engaged in mutual hostilities. There are two divisions larger than the rest, one of which, near the Abiad, or White River, retains its natural ferocity: they drink warm blood, adorn them¬ selves with the entrails of animals, and ride on oxen. The Assubee Galla wear garments like the Abyssinians ; grease and powder their hair; and cover their arms with bracelets, and with trophies, according to the number of the enemies slain. The inhabitants of Hamazen differ from the rest of the Abyssinians, being darker and stronger limbed, and more like the Funge, who live near Sennaar; they fight des¬ perately with two-edged swords. In the province ofWoj- jerat, also, the men are larger and stouter than the other Abyssinians. They are said to be the descendants of Portuguese soldiers. Their fidelity to their rulers is pro¬ verbial. The plain, eight hours’ distance from Wojjerat, is inhabited by the Doha, one of the isolated tribes of ne¬ groes found in all parts of Africa. They are mentioned by Alvarez, as, in his time, not marrying till they could make oath that they had put to death twelve Christians. The Agows, who were worshippers of the Nile till the seventeenth century, always fix their residence near the great branches of that river, for whose waters they still retain a veneration so great, that they will supply a stranger with milk, but not with water. Their buildings are without mortar. The houses of the higher ranks are in the form of Egyptian temples. At the earliest dawn of day they assemble before the doors of their chiefs, and chant their prayers, i inufac- It has already been mentioned, that one of the objects H1 es an(l of Mr Salt’s journeys was to ascertain whether Abyssinia imerce- was jjjjgjy f.0 affortt any new openings to British com¬ merce. How far this is likely, will best appear from a sketch of the manufactures and commerce of that coun¬ try. The former are few and contemptible : though cot¬ ton grows in many parts, and is of a superior quality, yet they import a considerable quantity from India, which they manufacture into a coarse cloth. As they have no dark blue colour, they unravel the threads of the blue cloth of Surat, and weave them again into their own webs: they procure a black dye from an earth, and red, yellow, and light blue from vegetables. Fine cloth is manufac¬ tured at Gondar, and coarse at Adowa ; the latter, besides its common use, circulates as money: a coarse piece six- Abyssinia, teen cubits long, one and three-fourths wide, is equal to* thirty pieces of salt, or one dollar; a piece not so coarse, fifty cubits long, sufficient to make a dress for a chief, is equal to twelve dollars. Coarse carpets, from sheeps’ wool, and the hair of goats dyed red and light blue, are manu¬ factured at Gondar and in Samen. In some parts the sheep-skins are tanned, and worn by the women round their waists, or over their shoulders, whenever they stir out. At Axum, skins are made into parchment, and finished well. Manufactures of iron and brass are com¬ mon ; the former is procured from Sennaar, Walkayt, and Berbera: knives are made at Adowa, and spears at An- talo: highly finished chains of brass are made by the Galla. There are many fairs and weekly markets. At a weekly market near Abha, were exposed for sale, iron, wrought and unwrought, for ploughshares, &c. cattle, horses, skins, cotton, ghee, butter in round balls and very white, &c. It is not infamous, as Mr Bruce asserts, for men to attend the markets. Through Adowa, there are imported for Gondar and the interior of Abyssinia, lead, block-tin, gold-foil, Per¬ sian carpets, raw silks from China, velvets, French broad cloths, coloured skins from Egypt, and glass beads and decanters from Venice. Ivory, gold, and slaves, are the principal exports through Adowa to the coast. A few slaves from Abyssinia reach Cairo, by way of Cossir and Suez; they are esteemed more beautiful than those of Soudan. In estimating the probability that Abyssinia may afford a new opening for British commerce, there are two cir¬ cumstances which require particular consideration. There can be no doubt, that, in so far as a more accurate know¬ ledge of the navigation of the Red Sea, and convenient places for landing the goods, are requisite for this object, the journeys of Lord Valentia and Mr Salt have been of great utility; but there can be no communication with Gondar and the interior of Abyssinia, unless we could either form an alliance with the chief who commands there,—in which case we should be exposed to the en¬ mity of the Ras of T^gre, and thus be prevented even from advancing to a short distance from the coast,—or assist the Ras to liberate his sovereign, and replace him on his throne. Direct assistance could not be given, and the result seems very doubtful were we only to furnish the Ras with a supply of arms. In the. second place, suppos¬ ing the communication with Gondar to be open and easy, Abyssinia at present can furnish nothing in exchange for our goods. We could indeed supply them, either from Britain or from our Indian possessions, with most of the articles which they procure from Arabia ; especial¬ ly with India goods and raw cotton from India, for which, as cotton is used for clothing in the greater part of Africa, there must be a great demand : besides, our goods could be sold cheaper, being exempt from the heavy duty im¬ posed on what they now import. But for exchange with us, Abyssinia produces only ivory and gold : the latter in small quantities; the former we can procure cheaper elsewhere. On the whole, therefore, when we consider that the communication with the interior will probably always be liable to interruption; and that, even if the case were other¬ wise, no returns could be looked for, except from the in¬ creased industry and skill of the Abyssinians, or from re¬ gions with which the intercourse is slow and precarious; there seems but little reason to expect that this country will afford any new openings to British commerce. f 64 A B Y Abyssi*. ABYSSINIAN, in Ecclesiastical History, is the name nian. 0f a sect in the Christian church, established in the em- pire of Abyssinia. The Abyssinians are a branch of the Copts or Jacobites, with whom they agree in admitting but one nature in Jesus Christ, and rejecting the council of Chalcedon: whence they are called Eutychians or Monophysites, and stand opposed to the Melchites. They are only distinguished from the Copts, and other sects of Jacobites, by some peculiar national usages. The Abys¬ sinian sect or church is governed by a bishop or metro¬ politan styled Abuna, sent them by the Coptic patriarch of Alexandria residing at Cairo, who is the only person that ordains priests. The next dignity is that of Komos, or Hegumenos, who is a kind of archpresbyter. They have canons also, and monks : the former of whom marry; the latter, at their admission, vow celibacy, but with a reservation: these, it is said, make a promise aloud, be¬ fore their superior, to keep chastity; but add in a low voice, as you keep it. The emperor has a kind of supre¬ macy in ecclesiastical matters. He alone takes cogni¬ zance of all ecclesiastical causes, except some smaller ones reserved to the judges; and confers all benefices, except that of Abuna. The Abyssinians have at different times expressed an inclination to be reconciled to the see of Rome; but rather out of interests of state than any other motive. The Emperor David, or the queen regent on his behalf, wrote a letter on this head to Pope Clement VII. full of submission, and demanding a patriarch from Rome to be instructed by; which being complied with, he publicly abjured the doctrine of Eutychius and Dioscorus in 1626, and allowed the supremacy of the pope. Under the em¬ peror Sultan Seghed all was undone again; the Romish missionaries settled there had their churches taken from them, and their new converts banished or put to death. The congregation de propaganda have made several at¬ tempts to revive the mission, but to little purpose.—The doctrines and ritual of this sect form a strange compound of Judaism, Christianity, and superstition. They prac¬ tise circumcision, and are said to extend the practice to the females as well as males; th^ observe both Satur¬ day and Sunday as Sabbaths ; they eat no meats prohi¬ bited by the law of Moses; women are obliged to the legal purifications ; and brothers marry their brothers’ wives, &c. On the other hand, they celebrate the Epi¬ phany with peculiar festivity, in memory of Christ’s bap¬ tism ; when they plunge and sport in ponds and rivers ; which has occasioned some to affirm that they were bap¬ tized anew every year. They have four Lents : the great one commences ten days earlier than ours, and is observ- fed with much severity, many abstaining therein even from fish, because St Paul says there is one kind of flesh of men, and another of fishes. They allow of divorce, which is easily granted among them, and by the civil judge ; nor do their civil laws prohibit polygamy itself. They have at least as many miracles and legends of saints as the Romish church ; which proved no small embarrassment to the Jesuit missionaries, to whom they produced so many miracles, wrought by their saints, in proof of their religion, and those so well circumstantiated and attested, that the Jesuits were obliged to deny miracles to be any evidence of a true religion ; and in proof hereof, to allege the same arguments against the Abyssinians which Pro¬ testants in Europe allege against Papists. They pray for the dead, and invoke saints and angels; have so great a veneration for the virgin, that they charge the Jesuits with not rendering her honour enough. They venerate images in painting ; but abhor all those in relievo, except the cross. They hold that the soul of man is not creat- A C A ed ; because, say they, God finished all his works on the Aca sixth day. They admit the apocryphal books, and the t| canons of the apostles, as well as the apostolical consti- tutions, for genuine. Their liturgy is given by Alvarez, and in English by Pagit; and their calendar by Ludolph. ACA, Ace, or Acon, in Ancient Geography, a town of Phoenicia, on the Mediterranean ; afterwards called Pto- lemais ; now Acre. ACACALOTI, the Brazilian name of a bird called by some corvus aquaticus, or the water raven : properly, the pelicanus carbo, or corvorant. ACACIA, Egyptian Thorn, or Binding Bean-tree, in Botany, a species of mimosa, according to Linmeus; though other botanists make it a distinct genus. The flowers of a species of the acacia are used by the Chinese in making that yellow which we see bears wash¬ ing in their silks and stuffs, and appears with so much elegance in their painting on paper. The method is this: They gather the flowers before they are fully open; these they put in a clean earthen vessel over a gentle heat, and stir them continually about as they do the tea-leaves, till they become dryish and of a yellow colour; then to half a pound of the flowers they add three spoonfuls of fair water, and after that a little more, till there is just enough to hold the flowers incorporated together; they boil this for some time, and the juice of the flowers mixing with the water, it becomes thick and yellow; they then take it from the fire, and strain it through a piece of coarse silk. To the liquor they add half an ounce of common alum, and an ounce of calcined oyster-shells reduced to a fine powder. All is then well mixed together; and this is the fine lasting yellow they have so long used. The dyers of large pieces use the flowers and seeds of the acacia for dyeing three different sorts of yellow'. They roast the flowers, as before observed ; and then mix the seeds with them, which must be gathered for this purpose when fully ripe : by different admixtures of these they give the different shades of colour, only for the deepest of all they add a small quantity of Brazil wood. Mr Geofff oy attributes the origin of bezoar to the seeds of this plant; which being browsed by certain animals, and vellicating the stomach by their great sourness and astringency, cause a condensation of the juices, till at length they become coated over with a stony matter, which we call Bezoar. Acacia, in the Materia Medica, the inspissated juice of the unripe fruit of the Mimosa Nilotica. The juice is brought to us from Egypt, in roundish masses wrapt up in thin bladders. It is outwardly of a deep brown colour, inclining to black; inwardly of a red¬ dish or yellowish brown; of a firm consistence, but not very dry. It soon softens in the mouth, and discovers a rough, not disagreeable taste, which is followed by a sweet¬ ish relish. This inspissated juice entirely dissolves in watery liquors, but is scarce sensibly acted on by recti¬ fied spirit. Acacia is a mild astringent medicine. The Egyptians give it in spitting of blood, in the quantity of a drachm, dissolved in any convenient liquor; and repeat this dose occasionally: they likewise employ it in collyria for strengthening the eyes, and in gargarisms for quinsy. Among us, it is little otherwise used than as an ingredi¬ ent in mithridate and theriaca, and is rarely met with in the shops. What is usually sold for the Egyptian acacia, is the inspissated juice of unripe sloes; this is harder, heavier, of a darker colour, and somewhat sharper taste, than the true sort. See the next article. German Acacia, the juice of unripe sloes inspissated nearly to dryness over a gentle fire, care being taken to II A C A A C A 65 L cacia prevent its burning. It is moderately astringent, similar I || to the Egyptian acacia, for which it has been commonly A'demy, substituted in the shops. It is given in fluxes, and other ^'v^'/,$sorders where styptic medicines are indicated, from a scruple to a drachm. Acacia, among antiquaries, something resembling a roll or bag, seen on models, as in the hands of several con¬ suls and emperors. Some take it to represent a handker¬ chief rolled up, wherewith they made signals at the games ; others, a roll of petitions or memorials ; and some, a purple bag full of earth, to remind them of their mortality. ACACIANS, in ecclesiastical history, the name of se¬ veral sects of heretics; some of which maintained, that the Son was only a similar, not the same, substance with the Father; and others, that he was not only a distinct but a dissimilar substance. Two of these sects had their denominations from Acacius, bishop of Caesarea, who lived in the fourth century, and changed his opinions so as, at different times, to be head of both. Another was named from Acacius, patriarch of Constantinople, who lived in the close of the fifth century. ACACIUS, surnamed Luscus, because he was blind of one eye, was bishop of Caesarea in Palestine, and suc¬ ceeded the famous Eusebius: he had a great share in the banishment of Pope Liberius, and bringing Felix to the see of Rome. He gave name to a sect, and died about !the year 365. He wrote the life of Eusebius, which is lost, and several other works. Acacius, Saint, bishop of Amida in Mesopotamia, in 420, was distinguished by his piety and charity. He sold the plate belonging to his church, to redeem seven thou¬ sand Persian slaves who were perishing with hunger. He gave each of them some money and sent them home. Veranius, their king, was so affected with this noble in¬ stance of benevolence, that he desired to see the bishop; and this interview procured a peace between that prince and Theodosius I. There have been several other eminent persons of the same name; particularly, a martyr under the Emperor Decius; a patriarch of Antioch, who succeeded Basil in 458, and died in 459 ; a bishop of Miletum in the fifth century; a famous rhetorician in the reign of the Empe¬ ror Julian ; and a patriarch of Constantinople in the fifth century, who was ambitious to draw the whole power and ! authority of Rome by degrees to Constantinople, for which he was excommunicated by Pope Felix II. He in his turn passed sentence of excommunication against the pope. Still, however, he held his patriarchate till his death in 488. ACAD, or Achad, in Ancient Geography, the town in which Nimrod reigned, called Archad by the Seventy; Academics situated in Babylonia, to the eastward of the Tigris. || ACADEMICS, or Academists, a denomination given Academy, to the cultivators of a species of philosophy originally de-'^^-^^ rived from Socrates, and afterwards illustrated and en¬ forced by Plato, who taught in a grove near Athens, con¬ secrated to the memory of Academus, an Athenian hero ; from which circumstance this philosophy received the name of Academical. Before the days of Plato, philoso¬ phy had in a great measure fallen into contempt. The contradictory systems and hypotheses which had succes¬ sively been advanced were become so numerous, that, from a view of this inconstancy and uncertainty of human opinions, many were led to conclude, that truth lay be¬ yond the reach of our comprehension. Absolute and uni¬ versal scepticism was the natural consequence of this con¬ clusion. In order to remedy this abuse of philosophy and of the human faculties, Plato laid hold of the principles of the academical philosophy; and, in his Phaedo, reasons in the following manner: “ If we are unable to discover truth,” says he, “ it must be owing to two circumstances: either there is no truth in the nature of things; or the mind, from a defect in its powers, is not able to appre¬ hend it. Upon the latter supposition, all the uncertainty and fluctuation in the opinions and judgments of mankind admit of an easy solution: Let us therefore be modest, and ascribe our errors to the real weakness of our own minds, and not to the nature of things themselves. Truth is often difficult of access : in order to come at it, we must proceed with caution and diffidence, carefully examining every step ; and, after all our labour, we will frequently find our greatest efforts disappointed, and be obliged to confess our ignorance and weakness.” Labour and caution in the researches, in opposition to rash and hasty decisions, were the distinguishing charac¬ teristics of the disciples of the ancient academy. A phi¬ losopher possessed of these principles will be slow in his progress, but will seldom fall into errors, or have occa¬ sion to alter his opinion after it is once formed. In his essay on the academical or sceptical philosophy, Mr Hume has confounded two very opposite species of philosophy. After the days of Plato, the principles of the first academy were grossly corrupted by Arcesilaus, Carneades, &c. This might lead Mr Hume into the notion, that the aca¬ demical and sceptical philosophy were synonymous terms. But no principles can be of a more opposite nature than those which were inculcated by the old academy of So¬ crates and Plato, and the sceptical notions which were propagated by Arcesilaus, Carneades, and the other dis¬ ciples of the new academical school. ACADEMY. ^j^CADEMY, axaSjj/A/a, axaSjj^e/a, or i-mhrigita, (the first two forms being probably derived from axoj, medela, and driyog, populus, and the last from exag, procul or seorsim, and drifiog, populus), a garden, villa, or grove, situated in the Ceramicus, one of the suburbs of Athens, about six stadia, or nearly a Roman mile to the north-west of the city. The common tradition is, that it took its name from one Academus or Ecademus, the original owner, who was contemporary with Theseus, and made it a kind of gym¬ nasium ; and that after his death it retained his name, and was consecrated to his memory. When Castor and Pollux came to Athens to reclaim by force of arms the person of their sister Helena, who, according to the legend, ad been carried off by Theseus, and concealed in some VOL. II. obscure retreat by the ravisher, the Athenians declared that they knew not where the lady was to be found ; but as this answer was not deemed satisfactory by the warlike brothers, Academus, cognisant with the secret, and anxi¬ ous to avert a contest about so frivolous a subject of dis¬ pute, apprized them that she was concealed in the town of Aphidna; which was immediately attacked, taken by assualt, and razed to the ground. Grateful for this tradi¬ tionary service, the Lacedemonians, who worshipped the Dioscuri (Castor and Pollux), spared the house and gar¬ dens known by the name of the Academy, when they ravaged the suburbs of Athens; and, in consideration of the disclosure just mentioned, they honoured the me¬ mory of the original owner, from whom the place took its I ACADEMY. 66 .Academy, name.1 Such is the legend which the Greek writers have transmitted to us. With regard to the spot itself, which afterwards became so famous, in connection with the name of Plato and his philosophical disciples, it appears to have remained almost in a state of nature, covered with stag¬ nant water, and exceedingly insalubrious, until the time of Cimon, when it was drained, planted with alleys of trees, and embellished with groves and with fountains: after which it became the promenade of the most distinguished Athenians, and particularly of the Platonic philosophers, thence called the Academics ; just as the Lyceum, another gymnasium, situated to the south-east of Athens, became the pi’omenade of the Aristotelian sect of philosophers, called also Peripatetics (a mynursw, obambulo), from the locomotive fashion in which they communicated or dis¬ coursed concerning their peculiar doctrines. The Aca¬ demy formed part of the Ceramicus (a word derived from ■Aipayog, signifying potter s earth or earthen vase, from its being filled with cinerary urns), and was therefore devoted to purposes of sepulture; it being then the practice to inter in a public garden or grove, as in a sort of elysian field, those who had signalized themselves by rendering important services to their country. Cicero, desirous to revive or preserve the name of the Academy, bestowed.it on his villa or country-seat near Puzzuoli, where he loved to converse with his friends on philosophical subjects, and where, also, he composed his Academical Questions, his treatise on the Nature of the Gods, and his celebrated work on the Commonwealth, a considerable portion of which was, several years ago, recovered from rescribed or palimpsest manuscripts, by Signor Angelo Maio, libra¬ rian of the Vatican. Academy, in its generalized acceptation, is employed to signify a society of learned men, established for the im¬ provement of science, literature, or the arts. This term, as we have seen, is one of very high antiquity. It was amidst the umbrageous recesses of the gardens of Aca- demus, so favourable to philosophical meditation, that the divine Plato, surnamed the swan of the Academy, esta¬ blished his school, collected his disciples, and taught his sublime morality; wherefore the sect of this illustrious philosopher was called the Academic, and the philosophers who adopted his doctrines Academics. For a long pe¬ riod, accordingly, this title marked out the disciples of Plato alone; but it came afterwards to be applied to all those who belonged to the different learned or literary societies instituted, under the name of Academies, in imi¬ tation of the school of Athens, and in order to extend the boundaries of human knowledge. Of these institutions several were established in Athens itself, but none ever equalled the renown of that founded by Plato; and, in point of fact, they were merely schools where Arcesilaus, Carneades, Philo, Antiochus, and other philosophers of less note, explained the different systems with which each in his turn sought to supersede those of his predecessors, but which have since fallen into the most profound neglect Acadti and oblivion. Ptolemy Soter, having by his victories secured undis¬ turbed possession of the throne of Egypt, and wishing to unite to the title of conqueror the more glorious appella¬ tion of patron of learning, founded, under the name of Musaeon, the celebrated Academy of Alexandria, and provided it with a collection of books, which formed the nucleus of the Alexandrian library. Here he assembled the most distinguished philosophers and scholars of his time, charging them with the investigation of philosophical truth and the improvement of art; and it was to the care and re¬ searches of these eminent men and their successors that the famous library, commenced by Ptolemy, and after¬ wards so barbarously given up to the flames by the Caliph Omar, was enlarged and improved, until it became the pride of Egypt and the glory of the world. This academy, distinguished alike for its useful labours and its improve¬ ments in science, has served as a model to modern aca¬ demies, both as regards the principles on which it was founded, and the object and end of its institution. It admitted into the number of its associates the poets and philosophers of all countries: persons came from every part of the earth to seek instruction, or to deposit new information in its bosom : and all parties were enriched by the continual interchange of ideas and discoveries. For a long period it was the great centre of knowledge. All the literary treasures, scattered throughout the different countries which the tide of barbarism had overflowed, were there collected together: towards the period when Greece began to decline, the spirit and the genius which once pre¬ sided in her schools of philosophy were in some degree revived in that of Alexandria; and it shone forth like a resplendent beacon-light in the midst of the surrounding darkness, shooting forth rays which have traversed the long course of ages, and guided the academies of modern times in their researches and investigations. Rome had no academies. In the eyes of the conque¬ rors and masters of the world, the sciences appeared only a secondary object, and of comparatively little importance. This Virgil has admitted in his iEneid, where he says, that in art and in science the Romans must yield the palm to other nations, and content themselves with the glory of conquest, and a knowledge of the means by which it might be secured and maintained.2 The Latin poets and writers, indeed, were formed by the study of Greek models. But no national establishment fostered their genius and favoured their progress, either under the republic, which despised letters, or under the imperial tyrants, who dread¬ ed them. Augustus himself only patronised and reward¬ ed the poets who flattered him ; while Maecenas, in sur¬ rounding himself wdth assemblages of celebrated writers, thought less of extending the boundaries of learning, than of tasting the pleasures of learned society, and wearing off the fatigues of business amidst the sweets of an inter- 1 From certain expressions of Eupolis, and this among others, e» ivaxioa 'bov^cimi Bcov, “ in the umbrageous groves of the god Academus,” it would appear that this person was accounted not merely a hero, but a sort of divinity. Hence the Academy was con¬ secrated to Bacchus Academus, or to the beneficent sun of the ascending signs ; as the Lyceum with its tcmenos or hicus was dedicat¬ ed to Apollo Lycseus (so called from Xvkos, a wolf), or to the destroying sun of the descending signs of the zodiac: and hence also these schools were the astronomical symbols or representatives of the celestial houses of the two solstices; the Academy, of the higher, and the Lyceum, of the lower solstice. 2 Excudent alii spirantia mollius sera, Credo equidem; vivos ducent de marmore voltus; Orabunt caussas melius, ccelique meatus Describent radio, et surgentia sidera dicent: Tu regere imperio populos, llomane, memento; Hse tibi erunt artes; pacisque imponere morem, Parcere subjectis, et debellare superbos. , .

Ldemy. course entirely Epicurean, or of enjoyments such as lite- L.v'C'rature alone can afford to men of refined and cultivated miWhen the darkness which had settled down upon Eu¬ rope after the fall of the Western Empire began at length to disperse, and when a faint glimmering of light, symp¬ tomatic of slowly approaching day, began to flicker and tremble on the dusky brow of the long night of ignorance and barbarism, a passion for instruction became in some measure the mode, and gave birth simultaneously to a multitude of learned associations; and these proceeded at once to the study and improvement of the sciences and arts, long neglected, and almost lost in those very coun¬ tries where they had formerly been cultivated with the greatest success. The Gauls, however, although partial¬ ly civilized by the Romans and by Julian the philosopher (vulgarly called the Apostate), had relapsed, under the in¬ dolent and imbecile monarchs of the first race, into the most profound ignorance ; while the monks, who passed for learned men when they could read, were from policy op¬ posed to the instruction of the people. The spirit of mo¬ nopoly and exclusion was then, as afterwards, a prominent characteristic of the ecclesiastical system; and the danger of educating the people was as vehemently exaggerated as by certain alarmists of our own day. “ The clergy,” said Charlemagne, “ wish to monopolize all learning, and to continue the sole expounders of the sciences and the laws.” Nevertheless this prince, who would have done honour to an age far less barbarous, attempted to resusci¬ tate letters, with which he had some acquaintance ; and with this view he, encouraged by the celebrated Alcuin, founded in his palace an academy for promoting the study of grammar, orthography, rhetoric, poetry, history, and the mathematics. This academy was composed of the principal I ‘ wits of the court, Charlemagne himself being a member. In their academical conferences, every member was to give an account of the ancient authors which he had read ; and in order to efface all distinctions of rank among the acade¬ micians, he required each of them to choose a name pure¬ ly literary (as, for example, that of some ancient author or celebrated person of antiquity), which should in no degree serve to recall the birth, station, or dignity of the person assuming it. Accordingly, Egilbert, a young lord, and one of the grandees about the court, modestly took the name of Homer; the archbishop of Mayence called himself Damcetas; Alcuin became Flaccus Albinus; Eginhard, Calliopus ; Adelard, abbot of Corbie, Augustin; Theodulph, Pindar; and Charlemagne himself, somewhat forgetful of his own rule, David.1 Fantastical as all this may appear to us, it was nevertheless productive of good. The nobles, who had been accustomed to value themselves solely on their birth and ancestry, began to acquire a re¬ lish for more substantial distinctions, and to feel the force of Charlemagne’s remark, that the state was likely to be better served by men who had improved their minds and cultivated their talents, than by those who had no other re¬ commendation than overweening pride and a long pedigree. Hence the academy of Charlemagne soon obtained great celebrity; and although few monuments of its labours 67 remain, yet it unquestionably gave an impulse to learning, Academy, diffused a taste for knowledge, and probably laid the first foundations of the French language, which was then a rude idiom, composed of a barbarous mixture of the language of the Goths, of Latin, and of the dialect of Celtic spoken by the ancient Gauls. This idiom the academy subject¬ ed to principles, forming it into a regular language, which afterwards became the provencal, or language of romance: and when it had thus, as it were, been licked into shape, Charlemagne proposed to have the hymns, the prayers, and the laws translated into it, for the benefit of the peo¬ ple ; a proposal which reflects the greatest honour on his memory. But the clergy resolutely set their faces against an innovation which would have deprived them of part of their influence as the sole expounders both of the civil and the divine laws, and thus in a great measure frustrated the principal object which Charlemagne had in view in founding his academy. Still its labours, though in some respects neutralized by the personal interest of the monks, were not altogether useless, but, on the con¬ trary, were instrumental in diffusing the first gleams of light throughout France, and in preparing it to emerge from a state of barbarism. In the following century, Alfred, a man worthy of being classed with the first French legislator, founded an aca¬ demy at Oxford, which formed the basis of the University afterwards established there; but this being a school for instruction rather than an institution for exciting emula¬ tion among the instructed, it does not, for that reason, fall within the scope of the present article. About the same period the Moors of Spain, celebrated for their gal¬ lantry, their chivalrous manners, and their taste for poetry, music, and letters, had also their academies at Granada and Cordoba; but of the precise nature and object of these institutions little or nothing is known. In the year 1325, the Academy of the Floral Games was established at Toulouse. This academy is still in existence, and is of course the most ancient establishment of the kind in Europe. The members assumed the somewhat fantastical name of Maintainers of the Gay Science; and the prizes which it awarded, consisting of flowers of gold and silver, excited a strong spirit of emulation among the Troubadours of Languedoc and Provence. This society, to which Clemens Isaurus bequeathed the whole of his pro¬ perty, still enjoys a considerable reputation; and many of the young poets of France, who aspire to be one day crowned with the genuine laurels of Parnassus, repair to it, at the commencement of their career, to dispute for the violet, the marigold, the amaranth, and the eglantine. A whole host of academies sprung up in different coun¬ tries immediately after the revival of letters in the fifteenth century; but it was in Italy that they were most nume¬ rous, every city in fact having its own; and they were frequently distinguished by appellations remarkable either for their oddity or extravagance. Thus, Rome had its Lincei; Naples, its Ardenti; Parma, its Insensati; and Genoa, its Addormentati;—names which some modern academicians might adopt without the slightest impro¬ priety. Many flourishing academies existed in France 1 Some modern writers have supposed that this assumption of ancient or classical names originated in an ardent admiration of an¬ tiquity, blended with the genius of an age essentially pedantic ; and thus they have endeavoured to account for Alcuin taking the surname of Horace as a prsenomen, and calling himself Flaccus Albinus. But from what is stated in the text, this appears to be a mistake. With regard to the circumstance of Charlemagne taking the name of David, which, as a royal one, appears to have been a contravention of his own rule, it is evident that his choice was determined by his passion for the composition ot canticles or psalms, in which he believed himself to be eminently skilful, and also by his decided preference of sacred to profane literature. 1 he empe¬ ror, in fact, had great pretensions as a theologian ; and on one occasion, when reproaching Iteibode, archbishop of Treves, with his admiration of Virgil’s poetry, he remarked of himself, that he would much rather possess the spirit of the four evangelists than that of the twelve books of the ASneid. 68 ACADEMY. Academy, before the Revolution, most of them having been esta- v^v-'^blished and endowed by the munificence of Louis XIV. In Britain we have but few, and those of the greatest note fall to be classed under a different appellation, name¬ ly, Society, to which the reader is referred. In giving an account of the principal academies, which is all that this article professes to do, we shall, for the sake of clearness, arrange them under different heads, accord¬ ing to the subjects for the cultivation and improvement of which they were instituted. And we shall commence with I. Medical Academies. Of this description are, the Academy of the Naturce Curiosi of Germany; that found¬ ed at Palermo in 1645; that established at Venice in 1701, which used to meet weekly in a hall near the grand hospital; and an institution which took its rise at Geneva in 1715. The Royal Colleges of Physicians at London and Edinburgh have also been ranked by some in the number of academies, but, in our opinion, erroneously; for they are rather of the nature of corporations, organized with a view to guard the privileges and promote the in¬ terests of a particular profession, than academies insti¬ tuted for facilitating the advancement of medical science. This is the exclusive object of the Royal Medical Society, and other institutions of the same sort; which, however, fall to be treated of under a different head, viz. that of Society. The Academy of Naturae Curiosi, called also the Leo- poldine Academy, was founded in 1662, by J. L. Bau- schius, a physician, who, imitating the example of the English, published a general invitation to medical men to communicate all extraordinary cases that occurred in the course of their practice: and, the scheme meeting with success, the institution was regularly organized, and Bauschius elected president. The works of the Naturae Curiosi were at first published separately; but this being attended with considerable inconvenience, a new arrange¬ ment was formed, in 1770, for publishing a volume of obser¬ vations annually. From some cause, however, the first volume did not make its appearance until 1784, when it came forth under the title of Ephemerides ; and the work was afterwards continued, at irregular intervals, and with some variations in the title. In 1687, the Emperor Leo¬ pold took the society under his protection, and granted its members several privileges, the most remarkable of which was, that its presidents should be entitled to enjoy the style and rank of counts palatine of the holy Roman empire; and hence the title of Leopoldine which it in consequence assumed. But though it thus acquired a name, it had no local habitation or fixed place of meeting, and no regular assemblies; instead of which there was a kind of bureau or office, first established at Breslau, and afterwards removed to Nuremberg, where letters, observations, and communications from correspondents, were received, and persons properly qualified admitted as members. By its constitution, the Leopoldine Aca¬ demy consists of a president, two adjuncts or secre¬ taries, and colleagues or members, without any limita¬ tion as to numbers. At their admission, the last come under a twofold obligation; first, to choose some subject for discussion out of the animal, vegetable, or mineral kingdom, provided it has not been previously treated of by any colleague of the academy; and, secondly, to apply . themselves to furnish materials for the annual Epheme¬ rides. Each member also bears about with him the symbol of the academy, consisting of a gold ring, whereon is represented a book open, with an eye on one side, and on the other the academical motto of Nunquam otiosus. II. Chirurgical Academies. An association of this sort was, not many years ago, instituted, by public au¬ thority, at Paris; the members of which were not only ^cade to publish their own observations and improvements, and'^-y those of their correspondents, but also to give an account of the various publications on surgery, and to compose a complete history of the art from the works of all the authors, ancient and modern, who have treated of it. Be¬ sides, a question in surgery was to be annually proposed, as the subject of a prize essay, and a gold medal of the value of 200 livres given to the successful competitor. The Academy of Surgery at Vienna was instituted by the present emperor, under the direction of the celebrat¬ ed Brambella. In it there were at first only two profes¬ sors; and to their charge the instruction of a hundred and thirty young men was committed, thirty of whom had formerly been surgeons in the army. But latterly the number both of teachers and pupils was considerably in¬ creased. Gabrielli was appointed to teach pathology and practice; Boecking, anatomy, physiology, and physics; Streit, medical and pharmaceutical surgery; Hunczowsky, surgical operations, midwifery, and the chirurgia forensis; and Plenk, chemistry and botany. To these was also added Beindel, as prosector and extraordinary professor of surgery and anatomy. Besides this, the emperor pro¬ vided a large and splendid edifice in Vienna, which af¬ fords accommodation both for the teachers, the students, pregnant women, patients for clinical lectures, and ser¬ vants. For t^e use of this academy the emperor also pur¬ chased a medical library, which is open every day ; a com¬ plete set of chirurgical instruments ; an apparatus for ex¬ periments in natural philosophy; a collection of natural history ; a number of anatomical and pathological prepa¬ rations ; a collection of preparations in wax, brought from Florence ; and a variety of other useful articles. Adjoin¬ ing to the building, also, there is a good botanical garden. With a view to encourage emulation among the students of this institution, three prize medals, each of the value of 40 florins, are annually bestowed on those who return the best answers to questions proposed the year before. These prizes, however, are not entirely founded by the emperor, but are in part owing to the liberality of Bren- dellius, formerly protochirurgus at Vienna. III. Ecclesiastical Academies. Under this head may be mentioned the academy at Bologna in Italy, instituted in 1687, for the purpose of investigating the doctrine, discipline, and history, of each age of the church. IV. Cosmographical Academies; as that at Venice, called the Argonauts. This was instituted at the solicita¬ tion of F. Coronelli, for the improvement of geographical knowledge. Its design was to publish exact maps, parti¬ cular as well as general, both of the celestial and terres¬ trial sphere, together with geographical, historical, and astronomical descriptions. Each member, in order to defray the expense of such a publication, was to subscribe a proportional sum, for which he was to receive one or more copies of each piece published. To this end three societies were established ; one under F. Moro, provincial of the Minorites in Hungary; another under the Abbot Laurence au Ruy Payenne au Marais; and the third un¬ der F. Baldigiani, Jesuit, professor of mathematics in the Roman College. Ihe device of this academy is the ter¬ raqueous globe, with the motto Plus ultra; and at its expense all the globes, maps, and geographical writings of I. Coronelli have been published. In the year 1799, a Geographical Academy was esta¬ blished at Lisbon, principally for the purpose of elucidat¬ ing the geography of Portugal. By the labours of the members of this academy, an accurate map of the coun¬ try, which was much wanted, has been completed. V. Academies of Science. These comprehend such ACADEMY. Aulemy. as have been erected for improving natural and mathe- urv-^S matical knowledge, and are otherwise called Philosophical and Physical Academies. The first of these was instituted at Naples, about the year 1560, in the house of Baptista Porta. It was called the Academy Secretmum Naturce; and was succeeded by the Academy of Lined, founded at Rome by Prince Frederic Ceoi, towards the end of the same century. This academy was afterwards rendered famous in conse¬ quence of the discoveries made by some of its members, among whom, the first place is due to the celebrated Ga¬ lileo, one of the most illustrious names of which the his¬ tory of science can boast. Several other academies, in¬ stituted about this time, also contributed to the advance¬ ment of the sciences; but none of them was in any re¬ spect comparable to that of the Lined. Some years after the death of Torricelli, the Accademia del Cimento made its appearance, under the protection of Prince Leopold, afterwards Cardinal de’ Medici. Redi was one of its chief members. In so far as regards the studies pursued by the other academicians, a very correct idea of them may be formed from the curious experiments pub¬ lished in 1667, by their secretary Count Laurence Magu- lotti, under the title of Saggi di JSaturali Esperienze ; a copy of which was presented to the Royal Society, trans¬ lated into English by Mr Waller, and published at Lon¬ don in 4to. The Accademia degVLnquieti, afterwards incorporated into that of Della Tracia, in the same city, followed the example of that of Del Cimento. Some excellent dis¬ courses on physical and mathematical subjects, by Gemi- niano Montenari, one of the chief members, were published in 1667, under the title of Pensieri Fisico-Matematici. The Academy of Rossano, in the kingdom of Naples, was originally an academy of belles lettres, founded in 1540, and transformed into an academy of sciences in 1695, at the solicitation of the learned abbot Don Giacin- to Gimma; who being made president, under the title of Promoter General of the institution, gave it a new set of regulations. He divided the academicians into the fol¬ lowing classes: grammarians, rhetoricians, poets, histo¬ rians, philosophers, physicians, mathematicians, lawyers, and divines; with a class apart for cardinals and persons of quality. To be admitted a member, it was requisite to have taken a degree in one or other of the faculties. The members were not allowed to take the title of Academi¬ cians mthc title-pages of their works, without a written permission from their president, which was not granted till their works had been examined by the censors of the academy; and this permission was the greatest honour the academy could confer, as they thereby adopted the works thus examined, and became answerable for them against all criticisms that might be made upon them. To this law the president or promoter himself was subject; and no aca¬ demician was allowed to publish anything against the writ¬ ings of another without leave obtained from the society. But Italy boasts of a number of scientific academies besides those above mentioned. The Royal Neapolitan Academy was established in 1779; and the published memoirs contain some valuable researches on mathema- ica subjects. The Royal Academy of Turin was esta¬ blished by the late king when duke of Savoy. Its memoirs were originally published in Latin, under the title of Mis¬ cellanea 1 hilosophica Mathematica Societatis Privata: Taud- Mnsis; and the first volume appeared in 1759. Among the original members of this institution the most cele¬ brated was Lagrange, who burst on the scientific world quite unexpectedly, by the novelty and depth of his papers m the first volume of the transactions. An Aca- 69 demy of Sciences, Belles Lettres, and Arts, was established Academy, at Padua by the senate, near the close of the eighteenth' century. It is composed of twenty-four pensionaries, twelve free associates, twenty-four pupils, twelve asso¬ ciates belonging to the ci-devant Venetian States, and twenty-four foreigners, besides honorary members. It has published several volumes of memoirs in the Ita¬ lian language. The Academy of Sciences and Belles Lettres of Genoa was established in 1783. It consists of thirty-two members; but their labours have been chiefly directed to poetry, nor are we aware that they have published any memoirs. The Academy of Milan was preceded, and perhaps introduced, by a literary as¬ sembly, consisting of ten persons, who published a sheet weekly, containing short remarks on subjects of science, belles lettres, and criticism. This society terminated in 1767. But soon afterwards another was established, the transactions of which, published under the title of Scelta d’Opuscoli Scientifici, contain several very interesting pa¬ pers. The Academy of Sciences at Siena, instituted in 1691, published the first volume of its transactions in 1761, and has since continued them, at long intervals, un¬ der the title of Atti dell'Accademia di Siena. Between the years 1770 and 1780, M. Lorgna established at Ve¬ rona an academy of sciences of a novel description. The object of it was to form an association among the princi¬ pal scientific men in all parts of Italy, for the purpose of publishing their memoirs. The first volume appeared in the year 1782, under the title of Memode di Matematica e Fisica della Societa Italiana. The most celebrated names that appear in this volume are those of Boscovich, the two Fontanas, and Spallanzani. There are also sci¬ entific academies at Mantua, Pisa, Pavia, and Modena; but several of these do not publish their transactions. Towards the beginning of the seventeenth century, F. Mersenne is said to have given the first idea of a philoso¬ phical academy in France, by the conferences of naturalists and mathematicians occasionally held at his lodgings. At these Gassendi, Descartes, Hobbes, Roberval, Pascal, Blondel, and other celebrated persons, assisted. F. Mer¬ senne proposed to each certain problems to be examined, or certain experiments to be made, and acted, to use a Gallic idiom, as the centre of re-union. By and by these private assemblies were succeeded by more public ones, formed by M. Montmort, and by Thevenot the celebrated traveller. Nor was this spirit confined to France. Ani¬ mated by the example which had been set in that coun¬ try, several Englishmen of learning and distinction insti¬ tuted a kind of philosophical academy at Oxford towards the close of Cromwelfs government; and this, after the Restoration, was erected into a Royal Society. (See So¬ ciety.) And the English example, in its turn, re-acted upon France; for, in 1666, Louis XIV., assisted by the counsels of Colbert, founded at Paris The Royal Academy of Sciences. Being desirous of establishing the sciences, arts, and literature upon a solid foundation, Louis, immediately after the peace of the Py¬ renees, directed M. Colbert to form a society of men of known abilities and experience in the different branches of knowledge, who should meet together under the king’s protection, in order to communicate freely their respective discoveries ; and with the view of carrying his design the more effectually into execution, he appropriated a suffi¬ cient revenue, not only to defray the charge of experi¬ ments, but likewise to afford moderate salaries to the mem¬ bers. The commands of the Grand Monarque were execut¬ ed with equal zeal and ability by his minister. For having conferred with those who were at that time most celebrat¬ ed for their learning, M. Colbert resolved to form a society 70 A C A D E M Y. Academy, of such persons as were conversant in natural philosophy and mathematics; to join to them persons skilled in his¬ tory and other branches of erudition ; and, lastly, to draw together those who were engaged in the cultivation of what was then called the belles lettres, as well as of grammar, eloquence, and poetry. The geometricians and natural philosophers were ordered to meet on Tues¬ days and Saturdays, in a great hall of the king’s library, where the books of mathematics and natural philosophy were contained; the learned in history to assemble, on Mondays and Thursdays, in the hall where the books of history were arranged; and the class of belles lettres to meet on Wednesdays and Fridays; while all the dif¬ ferent classes were directed to assemble together upon the first Thursday of every month, and by their respective secretaries to make a report of the proceedings of the pre¬ vious month. In a short time, however, the classes of history and belles lettres were united to the French Aca¬ demy, which was originally instituted for the improvement of the French language; in consequence of which the Royal Academy contained only two classes, viz. that of natural philosophy and that of mathematics. In the year 1696, the king, by an ordonnance datecf the 26th of January, gave this academy a new form, and put it upon a footing still more respectable. By this decree it was provided, that henceforth it should consist of four descrip¬ tions of members, viz. honorary, pensionary, associates, and eleves ; which last were a kind of pupils or scholars, one of whom was attached to each of the pensionaries. The first class was to contain ten persons, and each of the rest twenty. The honorary academicians were to be all inhabitants of France, the pensionaries were all to reside in Paris, and the eleves were also to live in the capital; but eight of the associates might be chosen from among foreigners. The officers were, a president, named by the king out of the class of honorary academicians, and a secretary and treasurer, who held their offices for life. Of the pensionaries, three were to be geometricians, three astronomers, three mechanicians, three anatomists, three botanists, and the remaining two perpetual secretary and treasurer. Of the twelve associates, two were to apply themselves to geometry, two to botany, and two to che¬ mistry ; while the eleves were to devote themselves to the particular branches of science cultivated by the pension¬ aries to whom they were respectively attached, and not to speak except when called to do so by the president. Clerical persons, whether regular or otherwise, were de¬ clared inadmissible, except into the class of honorary academicians; nor could any one be admitted an associate or pensionary unless known by some considerable printed work, some machine, or other discovery. The assemblies were held on Wednesdays and Saturdays, except when either chanced to be a holyday; in which case the meeting was held on the day immediately preceding. To en¬ courage members to pursue their inquiries and researches, the king engaged to pay not only the ordinary pensions, but even to confer extraordinary gratifications according to the degree of merit displayed in their respective per¬ formances ; and, furthermore, his Majesty became bound, as we have already stated, to defray the whole expense of experiments and other investigations which it might be judged necessary from time to time to institute. Flence, if any member gave in a bill of charges for experiments he had made, or desired the printing of any book, and ten¬ dered an account of the disbursements required to effect that object, the money was immediately paid by the king, upon the president’s allowing and signing the bill. In like manner, if an anatomist required, we shall say, live tor¬ toises in order to make experiments on the action and functions of the heart, he had only to signify his intention Acadei through the president, and as many as he pleased were^-^v brought him at the king’s charge. The motto of the aca¬ demy was Invenit et perfecit. In the year 1716, the Duke of Orleans, then regent, made an alteration in the constitution of this body, aug¬ menting the number of honorary members and of associ¬ ates eligible from among foreigners, admitting regular clergy among such associates, and suppressing the class of eleves, the existence of which had been attended with some inconveniences, particularly that of producing too great an inequality among the academicians, and of giving rise to misunderstandings and animosities among the mem¬ bers. At the same time he created two other classes; the one consisting of twelve adjuncts, who, like the as¬ sociates, were allowed a deliberative voice in matters re¬ lative to science; and the other of six free associates, who were not attached to any particular science, nor ob¬ liged to pursue any particular work. From the period of its re-establishment in 1699, this academy was very exact in publishing annually a volume containing either the works of its own members, or such memoirs as had been composed and read to the academy during that year. To each volume was prefixed a his¬ tory of the academy, or an extract of the memoirs and of the res gestcc of the different sittings ; and appended to the history were eloges pronounced on such academicians as had died in the course of the year. M. Rouille de Mes- lay, counsellor to the parliament of Paris, founded two prizes, one of 2500 and the other of 2000 livres; the for¬ mer for the best work, essay, or treatise, on physical as¬ tronomy, and the latter for any treatise or improvement relating to navigation and commerce. But notwithstand¬ ing all the advantages which the members of this aca¬ demy enjoyed, and the great facilities afforded them for the prosecution of their researches, the institution latterly degenerated; in consequence, doubtless, of the perpetual in¬ terference of the court in behalf of its favourites, or to effect the exclusion of men of unquestionable merit who had in¬ curred its displeasure. The effect of all this was, that persons of inferior acquirements were frequently admitted, while those of the most distinguished talents and reputation were excluded ; and hence it gradually sunk in public es¬ timation, until admission not only ceased to be an honour, but even became a subject of contempt and derision. Hence the well-known lines— Ci git Pirot, qui ne fut rien, Pas meme Academicien. The Revolution swept away the academy amidst the wrecks of the monarchy. It was suppressed by the Con¬ vention in the year 1793; and being new-modelled and re-organized upon a better and more efficient plan, it received the name of Institute, an appellation which it still bears, notwithstanding the great political changes which have since taken place. See Institute. The French had also considerable academies in most of their great cities. Montpellier, for example, had a royal academy of sciences on nearly the same footing as that at Paris, of which, indeed, it was in some measure the counterpart; Toulouse also had an academy under the denomination of Lanternists; and there were analogous institutions at Nismes, Arles, Lyons, Dijon, Bordeaux, and other places. Of these several, we believe, are still in existence, if not in activity. The Foyal Academy of Sciences at Berlin was founded in 1700, by Frederic II. king of Prussia, on the model of the Royal Society of England; excepting that, besides natural knowledge, it likewise comprehended the belles lettres. In 1710, it was ordained that the president should ACADEMY. .demy, be one of the counsellors of state, and nominated by the king. The members were divided into four classes : the first for prosecuting physics, medicine, and chemistry; the second for mathematics, astronomy, and mechanics ; the third for the German language and the history of the country; and the fourth for oriental learning, particularly in so far as it concerns the propagation of the gospel among heathen nations. Each class was empowered to elect a director for itself, who should hold his post for life. The members of any of the classes were entitled to free ad¬ mission into the assemblies of the other classes. The great promoter of this institution was the celebrat¬ ed Leibnitz, equally distinguished as a jurist, philologist, linguist, antiquary, mathematician, and philosopher, and who accordingly was chosen the first director. The first volume of their transactions was published in 1710, under the title of Miscellanea Berolinensia; and although the institution received but few marks of the royal favour for some time, they continued to publish new volumes in 1723, 1727, 1734, and 1740. But Frederic III., the late king of Prussia, at length imparted new vigour to this academy, by inviting to Berlin such foreigners as were most dis¬ tinguished for their merit and literature, at the same time that he encouraged his own subjects to prosecute the study and cultivation of the sciences ; and thinking that the aca¬ demy, over which some minister or opulent nobleman had till that time presided, would derive advantage from having a man of letters at its head, he conferred that honour on M. Maupertuis. At the same time he gave a new set of regulations to the academy, and took upon himself the title of its protector. The effect of these changes, however, it is not neces¬ sary to enlarge upon, as innovations still more recent have been introduced, with a view to direct the attention of the members to researches of real utility, to improve the arts, to stimulate national industry, and to purify the dif¬ ferent systems of moral and literary education. To attain these ends a directory was chosen, consisting of a presi¬ dent and the four directors of the classes, and two men of business, not members of the academy, though at the same time persons of acknowledged learning; and to the body thus constituted was intrusted the management of the funds, and the conduct of the economical affairs of the institution. I he power of choosing membei'S was granted to the academy; but the king reserved to him¬ self the privilege of confirming or annulling their choice, as he might think fit. The public library at Berlin, and the collection of natural curiosities, were united to the academy, and intrusted to its superintendence. The academicians hold two public assemblies annually ; at the latter of which is given, as a prize, a gold medal of fifty ducats value. The subject prescribed for this prize is successively taken from natural philosophy, mathema¬ tics, metaphysics, and general erudition. The Imperial Academy of Sciences at St Petersburg was projected by the Czar Peter the Great. That despotic reformer, haying in the course of his travels observed the advantage of public societies for the encouragement and promotion of literature, formed the design of founding an afdemy of sciences at St Petersburg. By the advice of Wolf and Leibnitz, whom he consulted on this occa¬ sion, the society was accordingly regulated, and several earned foreigners were invited to become members. I eter himself drew the plan, and signed it on the 10th of February 1724 ; but he was prevented, by the suddenness ot his death, from carrying it into execution. His de- cease, however, did not prevent its completion; for on ie ~lst of December 1725, Catharine I. established it according to Peter’s plan, and on the 27th of the same month the society assembled for the first time. On the 1st Academy, of August 1726, Catharine honoured the meeting with her' presence, when Professor Bulfinger, a German naturalist of great eminence, pronounced an oration upon the ad¬ vances made in the theory of magnetic variations, and also on the progress of research in so far as regarded the discovery of the longitude. A short time afterwards the empress settled a fund of L.4982 per annum for the sup¬ port of the academy; and fifteen members, all eminent for their learning and talents, were admitted and pension¬ ed, under the title of Professors in the various branches of science and literature. The most distinguished of these professors were Nicholas and Daniel Bernoulli, the two De Lisles, Bulfinger, and Wolf. During the short reign of Peter II. the salaries of the members were discontinuetl, and the academy utterly ne¬ glected by the court; but it was again patronised by the Empress Anne, who even added a seminary for the edu¬ cation of youth, under the superintendence of the pro¬ fessors. Both institutions flourished for some time under the direction of Baron Korf; but upon his death, towards the latter end of Anne’s reign, an ignorant person being appointed president, many of the most able members quitted Russia. At the accession of Elizabeth, however, new life and vigour were infused into the academy. The original plan was enlarged and improved; some of the most learned foreigners were again drawn to Petersburg; and, what was considered as a good omen for the litera¬ ture of Russia, two natives, Lomonosof and Rumovsky, men of genius and abilities, who had prosecuted their studies in foreign universities, were enrolled among its members. Lastly, the annual income was increased to L. 10,659, and sundry other advantages were conferred upon the institutioh. The late Empress Catharine II., with her usual zeal for promoting the diffusion of knowledge, took this useful so¬ ciety under her immediate protection. She altered the court of directors greatly to the advantage of the whole body, corrected many of its abuses, and infused a new vigour and spirit into their researches. By her Majesty’s particular recommendation the most ingenious professors visited the various provinces of her vast dominions ; and as the funds of the academy were not sufficient to defray the whole expense of these expeditions, the empress sup¬ plied the deficiency by a grant of L.2000, which was re¬ newed as occasion required. The purpose and object of these travels will appear from the instructions given by the academy to the several persons who engaged in them. They were ordered to institute inquiries respecting the different sorts of earths and waters; the best methods of cultivating barren and desert spots; the local disorders incident to men and animals, together wuth the most efficacious means of re¬ lieving them; the breeding of cattle, particularly of sheep ; the rearing of bees and silk-worms ; the different places and objects for fishing and hunting; minerals of all kinds; the arts and trades; and the formation of a Flora Russica, or collection of indigenous plants. They were particularly instructed to rectify the longitude and latitude of the principal towns; to make astronomical, geographical, and meteorological observations; to trace the courses of the rivers; to construct the most exact charts; and to be very distinct and accurate in remark¬ ing and describing the manners and customs of the differ¬ ent races of people, their dresses, languages, antiquities, traditions, history, religion; in a word, to gain every information which might tend to illustrate the real state of the whole Russian empire. More ample instructions cannot well be conceived; and they appear to have been 72 ACADEMY. Academy, very zealously and faithfully executed. The consequence ^-^v^^has been, that perhaps no country can boast, within the space of so few years, such a number of excellent publi¬ cations on its internal state, its natural productions, its to¬ pography, geography, and history, and on the manners, customs, and languages of the different tribes who inhabit it, as have issued from the press of this academy. The first transactions of this society were published in 1728, and entitled Commentarii Academice Scientiarum Imperialis Petropolitance ad annum 1726, with a dedica¬ tion to Peter II. The publication was continued under this form until the year 1747, when the transactions were called Novi Commentarii Academice, &c.; and in 1777, the academy again changed the title into Acta Academice Scientiarum Imperialis Petropolitance, and likewise made some alteration in the arrangement and plan of the work. The papers, which had been hitherto published in the Latin language only, are now written indifferently either in that language or in French ; and a preface is added, en¬ titled Partie Historique, which contains an account of its proceedings, meetings, the admission of new members, and other remarkable occurrences. Of the Commentaries, fourteen volumes were published: the first of the New Commentaries made its appearance in 1750, and the twentieth in 1776. Under the new title of Acta Aca¬ demice, a number of volumes have been given to the public ; and two are printed every year. These transac¬ tions abound with ingenious and elaborate disquisitions upon various parts of science and natural history; and it may not be an exaggeration to assert, that no society in Europe has more distinguished itself for the excellence of its publications, particularly in the more abstruse parts of the pure and mixed mathematics. The academy is still composed, as at first, of fifteen professors, besides the president and director. Each of these professors has a house and an annual stipend from L. 200 to L.600. Besides the professors, there are four adjuncts, with pensions, who are present at the sittings of the society, and succeed to the first vacancies. The direction of the academy is generally intrusted to a per¬ son of distinction. The buildings and apparatus of this academy are ex¬ traordinary. There is a fine library, consisting of 36,000 curious books and manuscripts; together with an exten¬ sive museum, in which the various branches of natural history, &c. are distributed in different apartments. The latter is extremely rich in native productions, having been considerably augmented by the collections made by Pal¬ las, Gmelin, Guldenstaedt, and other professors, during their expeditions through the various parts of the Russian empire. The stuffed animals and birds occupy one apart¬ ment. The chamber of rarities, the cabinet of coins, &c. contain innumerable articles of the highest curiosity and value. The motto of the society is exceedingly modest: it consists of only one word, Paulatim. The Academy of Sciences at Bologna, called the Insti¬ tute of Bologna, was founded by Count Marsigli in 1712, for the cultivation of physics, mathematics, medicine, chemistry, and natural history. Its history is written by M. de Limiers, from memoirs furnished by the founder himself. The Academy of Sciences at Stockholm, or the Royal Swedish Academy, owes its institution to six persons of distinguished learning, amongst whom was the celebrated Linnaeus. They originally met on the 2d of June 1739, when they formed a private society, in which some dis¬ sertations were read; and in the latter end of the same year their first publication made its appearance. As the meetings continued and the members increased, the so¬ ciety attracted the notice of the king; and, accordingly, Acaden on the 31st of March 1741, it was incorporated under'^-'V' the name of the Royal Swedish Academy. Not receiv¬ ing any pension from the crown, it is merely under the protection of the king, being directed, like our Royal Society, by its own members. It has now, however, a large fund, which has chiefly arisen from legacies and other donations; but a professor of experimental philosophy, and two secretaries, are still the only persons who receive any salaries. Each of the members resident at Stock¬ holm becomes president by rotation, and continues in office during three months. There are two kinds of mem¬ bers, native and foreign; the election of the former de¬ scription takes place in April, that of the latter in July; and no money is paid at the time of admission. The disserta¬ tions read at each meeting are collected and published four times in the year: they are written in the Swedish language, and printed in octavo; and the annual publica¬ tions make a volume. The first forty volumes, which were completed in 1779, are called the Old Transac¬ tions ; for in the following year the title was changed into that of New Transactions. The king is often present at the ordinary meetings, and regularly attends the annual as¬ sembly in April for the election of members. Any per¬ son who sends a treatise which is thought worthy of being printed, receives the Transactions for that quarter gratis ; together with a silver medal, which is not esteemed for its value, being worth only three shillings, but for its rarity and the honour conveyed by it. All the papers relating to agriculture are published separately under the title of (Economica Acta. Annual premiums, in money and gold medals, principally for the encouragement of agriculture and inland trade, are also distributed by the academy. The fund for these prizes is supplied by private donations. The Royal Academy of Sciences at Copenhagen owes its institution to the zeal of six individuals, whom Christian VI., in 1742, ordered to arrange his cabinet of medals. These persons were, John Gram, Joachim Frederic Ramus, Christian Louis Scheid, Mark Woldickey, Eric Ponto- pidan, and Bernard Moelman, who, occasionally meeting for this purpose, extended their designs ; associated with them others who were eminent in several branches of science ; and forming a kind of literary society, employed themselves in searching into, and explaining the history and antiquities of their country. The Count of Holstein, the first president, warmly patronised this society, and recommended it so strongly to Christian VI. that, in 1743, his Danish majesty took it under his protection, called it the Royal Academy of Sciences, endowed it with a fund, and ordered the members to join to their former pur¬ suits, natural history, physics, and mathematics. In con¬ sequence of the royal favour, the members engaged with fresh zeal in their pursuits; and the academy has pub¬ lished fifteen volumes in the Danish language, some of which have been translated into Latin. The American Academy of Sciences was established in 1780, by the council and house of representatives in the province of Massachusetts Bay, for promoting a knowledge of the antiquities of America, and of the natural history of the country; for determining the uses to which its various natural productions might be applied; for en¬ couraging medicinal discoveries, mathematical disquisi¬ tions, philosophical inquiries and experiments, astronomi¬ cal, meteorological, and geographical observations, and im¬ provements in agriculture, manufactures, and commerce; and, in short, for cultivating every art and science which may tend to advance the interest and increase the hap¬ piness of the people. The members of this academy can never exceed 200, nor fall below forty. ACADEMY. 73 AcJemy.

Academy, livres. The academy consisted of a protector, a vice- protector, a director, a chancellor, four rectors, adjuncts to the rectors, a treasurer, fodr professors (one of whom was professor of anatomy, and another of geometry), seve¬ ral adjuncts and counsellors, an historiographer, a secre¬ tary, and two ushers. Every day for two hours in the afternoon, the Academy of Painting held a public assembly, to which the painters resorted either to design or to paint, while the sculp¬ tors modelled after the naked figure. There were twelve professors, each of whom kept the school for a month ; and there was an equal number of adjuncts to supply their places in case of need. The professor upon duty placed the naked figure as he thought proper, and set it in two different attitudes every week. This was what they call¬ ed setting the model. In one week of the month he set two models together, which was called setting the group. The paintings and models made after this model, were called academics, or academical figures. They had likewise a woman who stood as a model in the public school. Three prizes for design were distributed among the eleves or disciples every quarter; and four others, two for paint¬ ing, and two for sculpture, every year. There was also an Academy of Painting, Sculpture, &c. at Rome, established by Louis XIV., wherein those who had gained the annual prize at Paris were entitled to be three years entertained at the king’s expense, for their further improvement. In 1778, an Academy of Painting and Sculpture was established at Turin. Their meetings were held in the palace of the king, who distributed prizes among the most successful members. In Milan, an Academy of Architec¬ ture was established so early as the year 1380, by Galeas Visconti. About the middle of the last century, an Aca¬ demy of the Arts was established there, after the exam¬ ple of those at Paris and Rome. The pupils were fur¬ nished with originals and models, and prizes were distri¬ buted annually. The prize for painting was a gold medal, and no prize was bestowed till all the competing pieces had been subjected to the examination and criticism of competent judges. Before the effects of the French re¬ volution reached Italy, this was one of the best establish¬ ments of the kind in that kingdom. In the hall of the academy were some admirable pieces of Correggio, as well as several ancient paintings and statues of great me¬ rit ; particularly a small bust of Vitellius, and a statue of Agrippina, of most exquisite beauty, though it wants the head and arms. The Academy of the Arts, which had been long established at Florence, but which had fallen into decay, was restored by the late Grand Duke. In it there are halls for naked and plaster figures, for the use of the sculptor and the painter. The hall for plaster figures had models of all the finest statues in Italy, arranged in two lines; but the treasures of this, as well as all the other institutions for the fine arts, were greatly diminished by the rapacity of the French. In the saloon of the Aca¬ demy of the Arts at Modena, there are many casts of an¬ tique statues; but since it was plundered by the french it has dwindled into a petty school for drawings from living models : it contains the skull of Correggio. There is also an Academy of the Fine Arts in Mantua, and an¬ other at Venice. In Madrid, an Academy for Painting, Sculpture, and Architecture, was founded by Philip V. The minister for foreign affairs is president. Prizes are distributed every three years. In Cadiz, a few students are supplied by government with the means of drawing and modelling from figures; and such as are not able to purchase the requisite instruments are provided with them. An Academy of the Fine Arts was founded at Stock- AcadJj holm in the year 1733 by Count Tessin. In its hall arev->~v the ancient figures of plaster presented by Louis XIV. to Charles XL The works of the students are publicly ex¬ hibited, and prizes are distributed annually. Such of them as display distinguished talents obtain pensions from government, to enable them to reside in Italy for some years, for the purposes of investigation and improvement. In this academy there are nine professors, and generally about four hundred students. In the year 1705, an Academy of Painting, Sculpture, and Architecture was established at Vienna, with the view of encouraging and promoting the fine arts. The Royal Academy of Music is a name given in France to the grand opera, which is considered as in some sort a combination of all the liberal arts ; painting, music, and the dance forming the principal part of that enchanting spec¬ tacle. The opera is of Venetian origin; and the Abbe Perrin, who officiated as master of the ceremonies to Gas¬ ton, Duke of Orleans, was the first who introduced it at Paris. He obtained letters patent from the king, dated the 28th June 1669, conferring upon him the privilege of establishing Operatic Academies in Music and in French Verse throughout the kingdom. Latterly, the theatre where operas are represented has been denominated the Theatre des Arts ; a name which has probably been sug¬ gested by the following verses of Voltaire, which convey a just definition of this delightful entertainment:— II faut se rendre a ce palais magique, Ou les beaux vers, la danse, la musique, L’art de tromper les yeux par les couleurs, L’art plus heureux de sdduire les coeurs, De cent plaisirs font un plaisir unique. The Academy of Ancient Music was established in Lon¬ don in 1710, by several persons of distinction, and other amateurs, in conjunction with the most eminent masters of the time, in the view of promoting the study and practice of vocal and instrumental harmony. This institution, which had the advantage of a library, consisting of the most ce¬ lebrated compositions, both foreign and domestic, in ma¬ nuscript and in print, and which was aided by the per¬ formances of the gentlemen of the chapel royal, and the choir of St Paul’s, with the boys belonging to each, con¬ tinued to flourish for many years. In 1731, a charge of plagiarism brought against Bononcini, a member of the academy, for claiming a madrigal of Lotti of Venice as his own, threatened tlie existence of the institution. Dr Greene, who had introduced the madrigal into the aca¬ demy, took part with Bononcini, and withdrew from the society, taking with him the boys of St Paul’s. In 1734, Mr Gates, another member of the society, and master of the children of the royal chapel, also retired in disgust; so that the institution was thus deprived of the assistance which the boys afforded it in singing the soprano parts. From this time the academy became a seminary for the instruction of youth in the principles of music and the laws of harmony. Dr Pepusch, who was one of its foun¬ ders, was active in accomplishing this measure; and by the expedients of educating boys for their purpose, and admitting auditor members, the subsistence of the aca¬ demy was continued. The Royal Academy of Music M as formed by the principal nobility and gentry of the king¬ dom, for the performance of operas, composed by Mr Handel, and conducted by him at the theatre in the Hay- market. The subscription amounted to LAO,000, and the king, besides subscribing L.1000, allowed the society to assume the title of Royal Academy. It consisted of a governor, deputy-governor, and tM^enty directors. A con¬ test between Handel and Senesmo, one of the performers, ACADEMY. 75 idemy. in which the directors took the part of the latter, occa- v^Ogioned the dissolution of the academy, after it had subsist¬ ed with reputation for more than nine years. The Academy of Architecture was founded, under Louis XIV., by his celebrated minister Colbert in 1671, and was composed of the most distinguished architects of the time. It was provided, however, that the professor of architecture, and the secretary to the academy, should al¬ ways be chosen from those Architects intrusted with the superintendence of royal edifices ; and the title of acade¬ mician was conferred by brevet. The Academy of Archi¬ tecture held its sittings every Monday at the Louvre, where it occupied the apartment called the Queens Sa¬ loon ; but at the commencement of the Revolution it was remodelled, like the Academy of Sciences, and transform¬ ed into a school for the cultivation and improvement of the fine arts. This school was divided into two sections, the first of which was devoted to painting and sculpture, and the second to architecture; and these two sections received, by a royal ordonnance of the 11th August 1819, the title of Royal Academy of the Fine Arts. The in¬ struction in architecture at this institution consists of lessons given in special courses of lectures by four dif¬ ferent professors ; first, on the theory of the art; secondly, on its history; thirdly, on the mathematical principles of construction; and, fourthly, on perspective; which last branch is common to both sections. By the munificence of the government, this institution is amply provided with means for supporting the pupils admitted within its walls, as also for affording them every facility in the prosecution of their studies ; and with the view of exciting emulation as well as rewarding excellence, a grand prize is annually ‘ given. The Academy of Dancing was erected by Louis XIV., and had particular privileges conferred upon it. VII. Academies of Law. Under this head we may mention the famous academy at Berytus, and that of the Sitientes at Bologna. We are not aware of any other. VIII. Academies of History. The first of these to which we shall advert, is the Royal Academy of Portuguese History at Lisbon. This academy was instituted by King John V. in 1720. It consists of a director, four censors, a secretary, and fifty members, to each of whom is assign¬ ed some part of the ecclesiastical or civil history of the nation, which he is required to treat either in Latin or Portuguese. In the church history of each diocese, the prelates, synods, councils, churches, monasteries, acade¬ mies, persons illustrious for sanctity or learning, and places famous for miracles or relics, must be distinctly i*elated in twelve chapters. The civil history comprises the transac¬ tions of the kingdom, from the government of the Ro¬ mans down to the present time. The members who re¬ side in the country are obliged to make collections and extracts out of all the registers, &c. where they live. Their meetings take place once every fifteen days. A medal was struck by this academy in honour of their prince, on the obverse of which was his effigy, with the inscription Johannes V. Lusitanorum Rex, and on the reverse, the same prince represented standing, and raising History, almost prostrate before him, with the legend, Historia, Rxsurges. Underneath are the following words in abbre¬ viature : REGia ACADemia HISTorim LUSITan®, IN- SlITuta VI. Idus Decembris MDCCXX. An Academy of History was some time ago established by some learned men at Tubingen, for publishing the best historical writings, the lives of the chief historians, and compiling new memoirs on any matter of importance con¬ nected with either. 1 c About the year 1730, a few individuals in Madrid agreed to assemble at stated periods, for the purpose of pre- Academy, serving and illustrating the historical monuments of Spain. In the year 1738, the rules which they had drawn up were confirmed by a royal cedula of Philip V. This aca¬ demy consists of twenty-four members. The device is a river at its source ; the motto, Ln patriampopulumquefluit. It has published editions of Mariana, Sepulveda, Solis, and the ancient Chronicles relative to the affairs of Castile, several of which were never before printed. All the di¬ plomas, charters, &c. belonging to the principal cities in Spain, since the earliest period, are in its possession. It has long been employed in preparing a geographical dic¬ tionary of that country. IX. Academies of Antiquities; as that at Cortona in Italy, and that at Upsal in Sweden. The first is designed for the study of Pletrurian antiquities ; the other for illus¬ trating the northern languages, and the antiquities of Sweden, in which valuable discoveries have been made by it. The head of the Hetrurian academy is called Luco- mon, a name by which the ancient governors of the coun¬ try were distinguished. One of their laws is, to give audience to poets only one day in the year; and another is, to fix their sessions, and impose a tax of a dissertation on each member in his turn. The Academy of Medals and Inscriptions at Paris was set on foot by M. Colbert, under the patronage of Louis XIV. in 1663, for the study and explanation of ancient mo¬ numents, and for perpetuating great and memorable events, especially those of the French monarchy, by coins, relievos, inscriptions, &c. The number of members w’as at first con¬ fined to four or five, chosen out of those of the French acade¬ my ; and they met in the library of M. Colbert, from whom they received his Majesty’s orders. Though the days of their meetings were not determined, they generally as¬ sembled on Wednesdays, especially in the winter season; but, in 1691, the king having given the inspection of this academy to M. de Pontchartrain, comptroller-general of the finances, he fixed their meetings on Tuesdays and Saturdays. By a new regulation, dated the 16th of July 1701, the academy was composed of ten honorary mem¬ bers ; ten associates, each of whom had two declarative voices; ten pensioners; and ten eleves, or pupils. They then met every Tuesday and Wednesday, in one of the halls of the Louvre; and had two public meetings yearly, one the day after Martinmas, and the other the 16th after Easter. The class of eleves was suppressed, and united to the associates. The king nominated their president and vice-president yearly; but their secretary and treasur¬ er were perpetual. The rest were chosen by the mem¬ bers themselves, agreeably to the constitutions on that head given to them. One of the first undertakings of this academy was to compose, by means of medals, a con¬ nected history of the principal events of Louis XIV.’s reign. In this design, however, they met with very great difficulties, and consequently it was interrupted for a number of years; but at length it was completed down to the advancement of the Duke of Anjou to the crow* of Spain. In this celebrated work, the establishment of the academy itself was not forgotten. The medal on this subject represents Mercury sitting, and writing with an antique stylus on a table of brass ; he leans with his left hand upon an urn full of medals, and at his feet are several others placed upon a card. The le¬ gend is, Rerum gestarum fides, and on the exergue, Aca¬ demia Regia Inscriptionum et Numismatum, instituta MDCLXIII.; signifying, that the Royal Academy of Me¬ dals and Inscriptions, founded in 1663, ought to give to future ages a faithful testimony of all great actions. Be¬ sides this work, we have several volumes of their me- 76 ACADEMY. Academy, moirs; and their history, written and continued by their secretaries. Under this class the Academy of Herculaneum proper¬ ly ranks. It was established at Naples about 1^55, at which period a museum was formed of the antiquities found at Herculaneum, Pompeii, and other places, by the Marquis Tanucci, who was then minister of state. Its ob¬ ject was to explain the paintings, &c. which were discover¬ ed at those places ; and for this purpose the members met every fortnight, and at each meeting three paintings were submitted to three academicians, who made their report on them at their next sitting. The first volume of their labours appeared in 1775, and they have been continued under the title of Antichitd di Ercolarw. They contain engravings of the principal paintings, statues, bronzes, warble figures, medals, utensils, &c. with explanations. In the year 1807, an Academy of History and Antiquities, on a new plan, was established at Naples, by Joseph Buona¬ parte. The number of members was limited to forty; twenty of whom were to be appointed by the king, and these twenty were to present to him, for his choice, three names for each of those wanted to complete the full num¬ ber. Eight thousand ducats were to be annually allotted for the current expenses, and two thousand for prizes to the authors of four works, which should be deemed by the academy most deserving of such a reward. A grand meet¬ ing was to be held every year, when the prizes were to be distributed, and analyses of the works read. The first meeting took place on the 25th of April 1807 ; but the sub¬ sequent changes in the political state of Naples have pre¬ vented the full and permanent establishment of this insti¬ tution. In the same year an academy was established at Florence, for the illustration of Tuscan antiquities, which has published some volumes of memoirs. In consequence of the attention of several literary men in Paris having been directed to Celtic antiquities, a Celtic Academy was established in that city in the year 1807. Its objects were, first, the elucidation of the history, cus¬ toms, antiquities, manners, and monuments of the Celts, particularly in France ; secondly, the etymology of all the European languages, by the aid of the Celto-British, Welsh, and Erse; and, thirdly, researches relating to Druidism. The attention of the members was also parti¬ cularly called to the history and settlements of the Galatae in Asia. Lenoir, the keeper of the museum of French monuments, was appointed president. A fasciculus, con¬ sisting of 150 or 160 pages, was to be published monthly; and the engravings illustrative of Celtic antiquities were to be under the inspection of Lenoir. The devices are, Gloria. Majorum, and Sermonem patriam moresque re- quiret. X. Academies of Belles Lettres are those wherein eloquence and poetry are chiefly cultivated. These are very numerous in Italy, and were not uncommon in France. The Academy of Umidi at Florence has contributed greatly to the progress of the sciences by the excellent Italian translations executed by some of its members, of the ancient Greek and Latin historians. But their chief attention was directed to Italian poetry, at the same time that they applied themselves to the polishing of their lan¬ guage, which produced the Academy della Crusca. The Academy of Humourists, Umoristi, had its origin at Rome in the marriage of Lorenzo Marcini, a Roman gentleman, at which several persons of rank were guests; for it being carnival time, to give the ladies some diver¬ sion, they betook themselves to the reciting of verses, sonnets, speeches, first extempore, and afterwards preme¬ ditately ; which gave them the denomination of Bdli Hu- marl After some experience, and coming more and more Acade into the taste of these exercises, they resolved to form an^v academy of belles lettres, and changed the title of Belli Humori for that of Humoristi; choosing for their de¬ vice a cloud, which, after being formed of exhalations from the salt waters of the ocean, returns in a gentle sweet shower; with this motto from Lucretius, Redlt agmine dulci. In 1690, the Academy of Arcadi was established at Rome, for reviving the study of poetry and of the belles lettres. Besides most of the politer wits of both sexes in Italy, this academy comprehended many princes, cardi¬ nals, and other ecclesiastics ; and, to avoid disputes about pre-eminence, all appeared masked after the manner of Arcadian shepherds. Within ten years from its first establishment, the number 6f Academicians amounted to six hundred. They held assemblies seven times a year in a meadow or grove, or in the gardens of some noble¬ man of distinction. Six of these meetings were employed in the recitation of poems and verses of the Arcadi re¬ siding at Rome, who read their own compositions; ex¬ cept ladies and cardinals, who were allowed to employ others. The seventh meeting was set apart for the com¬ positions of foreign or absent members. This academy is governed by a custos, who represents the whole society, and is chosen every four years, with a power of electing twelve others yearly for his assistance. Under these are two sub-custodes, one vicar or pro-custos, and four depu¬ ties or superintendents, annually chosen. The laws of the society are immutable, and bear a near resemblance to the ancient model. There are five modes of electing members. The first is by acclamation. This is used when sovereign princes, cardinals, and ambassadors of kings desire to be ad¬ mitted ; and the votes are then given viva voce. The second is called annumeration. This was introduced in favour of ladies and academical colonies, where the votes are taken privately. The third, representation, was established in favour of colonies and universities, where the young gentry are bred, who have each a privilege of recommending one or two members privately to be balloted for. The fourth, surrogation, whereby new members are substituted in the room of those dead or expelled. The last, destination, whereby, when there is no vacancy of members, persons of poetical merit have the title of Arcadi conferred upon them till such time as a vacancy shall happen. All the members of this body, at their admission, assume new pas¬ toral names, in imitation of the shepherds of Arcadia. The academy has several colonies of Arcadi in different cities of Italy, who are all regulated after the same man¬ ner. XI. Academies of Languages, called by some, Gram¬ matical Academies ; as, The Academy della Crusca at Florence, famous for its voca¬ bulary of the Italian tongue, which was formed in 1582, but scarce heard of before the year 1584, when it became noted for a dispute between Tasso and several of its members. Many authors confound this with the Florentine academy. The discourses which Torricelli, the celebrated disciple of Galileo, delivered in the assemblies, concerning levity, the wind, the power of percussion, mathematics, and mili¬ tary architecture, are a proof that these academies applied themselves to things as well as words. The Academy of Fructiferi had its rise in 1617, at an assembly of several princes and nobility of the country, who met with a design to refine and perfect the German tongue. It flourished long under the direction of princes of the empire, who were always chosen presidents. In 1668, the number of members arose to upwards of nine hundred. It was prior in time to the French academy, ACADEMY. 77 A idemy. which only appeared in 1629, and was not established ^ into an academy before the year 1635. Its history is written in the German tongue, by George Neumarck. The French Academy had its rise from a meeting of men of letters in the house of M. Conrart, in 1629. In 1635, it was erected into an academy by Cardinal Riche¬ lieu, for refining and ascertaining the French language and style. The number of its members was limited to forty, out of whom a director, chancellor, and secretary were to be chosen; the two former of whom were to hold their posts for two months; the latter was perpetual. The members of this academy enjoyed several privileges and immunities, among which was that of not being obliged to answer be¬ fore any court but that of the king’s household. They met three limes a week in the Louvre. At the breaking up of each meeting forty silver medals were distributed among the members, having on one side the king of France’s head, and on the reverse, Protecteur de VAcademic, with laurel, and this motto, A FImmortalite. By this distribution, the attendance of the academicians was secured; for those who were present received the surplus intended for the absent. To elect or expel a member, the concurrence of at least eighteen was required; nor could any one be chosen unless he petitioned for it; by which expedient the affront of refusals on the part of persons elected was avoided. Re¬ ligious persons were not admitted ; nor could any nobleman or person of distinction be elected on any other footing than as a man of letters. None could be expelled, except for base and dishonest practices ; and there were but two in¬ stances of such expulsions, the first of M. Grainer for re¬ fusing to return a deposit, the other of the Abbe Fure- tiere for plagiarism. The design of this academy was to give not only rules, but examples, of good writing. They began with making speeches on subjects taken at pleasure, about twenty of which were printed. At their first insti¬ tution they jnet with great opposition from the parliament; it being two years before the patents granted by the king could be registered. This institution has been severely satirized, and the style of its compositions has been ri¬ diculed as enervating instead of refining the French lan¬ guage. They were also charged with having surfeited the world by flattery, and exhausted all the topics of pane¬ gyric in praise of their founder; it being a duty incumbent on every member, at his admission, to make a speech in praise of the king, the cardinal, the chancellor Seguier, and the person in whose room he is elected. The most remarkable work of this academy is a dictionary of the French tongue ; which, after fifty years spent in settling the words and phrases to be used in writing, was at last published in 1694. An academy similar to the ab»ve was founded at Peters¬ burg under the auspices of the Princess Dashkof; and the plan having been approved by the crown, a fund was esta¬ blished for its support. It is attached to the Imperial Academy of Sciences at St Petersburg. The Royal Spanish Academy at Madrid held its first meeting in July 1713, in the palace of its founder, the Duke d’Escalona. It consisted at first of eight acade¬ micians, including the duke; to which number fourteen others were afterwards added, the founder being chosen president or director. In 1714, the king granted them the royal confirmation and protection. Their device is a crucible in the middle of the fire, with this motto, Limpia, Fixa,' y da Esplendor ; “ It purifies, fixes, and gives bright¬ ness. The number of members was limited to twenty- four ; the Duke d’Escalona was chosen director for life, but his successors were elected yearly, and the secretary for life. 1 heir object, as marked out by the royal declaration, was to cultivate and improve the national language. They were to begin with choosing carefully such words and Academy! phrases as have been used by the best Spanish writers ;V^-vr's*-'' noting the low, barbarous, or obsolete ones ; and cofnpos- ing a dictionary wherein these might be distinguished from the former. The Royal Swedish Academy was founded in the year 1786, for the purpose of purifying and perfecting the Swe¬ dish language. A medal is struck by its direction every year in honour of some illustrious Swede. This academy does not publish its transactions. XII. Academies of Politics. Of this description was that at Paris, consisting of six persons, who met at the Louvre, in the chamber where the papers relating to fo¬ reign affairs were lodged. But this academy proved of little service, as the kings of France were unwilling to trust any but their ministers with the inspection of foreign af¬ fairs. Academy is a term also applied to those royal col¬ legiate seminaries in which young men are educated for the navy and army. In our country there are three se¬ minaries of this description ; the Naval Academy at Ports¬ mouth, the Royal Military Academy at Woolwich, and the Royal Military College at Farnham and Sandhurst. Of these we shall give some account in their order. I. The Naval Academy at Portsmouth was founded by George I. in 1722; but the official warrant for its esta¬ blishment does not appear to have been issued till the 21st of February 1729. This warrant bears, that the aca¬ demy was instituted for the education of forty young gentlemen, fifteen of whom were to be sons of commis¬ sioned officers in the navy. The commissioner of the navy at Portsmouth was, ex officio, to be governor; and there were to be two masters for the instruction of the students in navigation and the sciences introductory or auxiliary to it; besides a master for writing and drawing. The annual expense was about L.1169. In the year 1773, George III., during a visit he paid to Portsmouth, suggested the extension and improve¬ ment of the Naval Academy; but no steps were taken to¬ wards this object till the year 1806, when an order in council was issued for a new and enlarged establishment. By this order it was henceforward to be called the Royal Naval College, at Dock-yard, Portsmouth, and the follow¬ ing officers were appointed: first, a Governor, who was to be the First Lord of the Admiralty for the time being; and, second, a Lieutenant-Governor and inspector, who was to be a post-captain in the navy. As the course of edu¬ cation which the students were to follow necessarily em¬ braced the mathematical sciences, the order directed that the University of Cambridge should recommend three of its graduates, who were able mathematicians; one of whom, the First Lord of the Admiralty, as governor, was to nominate professor. In order to incite him to the re¬ gular and faithful discharge of his duty, he was to receive no fixed salary, but to be paid L.8 annually by each stu¬ dent attending the academy. The next in rank and au¬ thority under the professor is the preceptor, or head master, who must be a graduate of one of the universities. He has the control of the students at all hours, and is to instruct them in the classics, moral philosophy, geography, history, and general literature. The order in council also appointed a writing-master, who, besides giving instructions in his own immediate line, was to prepare the students for the lectures of the professor, by teaching them arithmetic, fractions, algebra, and geometry. There are, besides, masters for drawing, French, dancing, and fencing. The surgeon of the dock¬ yard gives his professional advice and assistance. The domestic economy of the establishment is intrusted, by 78 ACADEMY. Academy, the order in council, to a disabled and meritorious half- pay lieutenant. The peculiar advantages of this academy, however, consist in the practical knowledge which it is intended and calculated to bestow on those who are admitted. For this purpose, the master attendant of the dock-yard gives weekly lessons on the management of ships afloat, in one of the cruising sloops; and likewise lessons in rigging and preparing ships for sea, on board such vessels as are preparing to sail from Portsmouth harbour. Forty-seven lessons are given in each of these branches annually, five weeks being allowed for holydays. The master shipwright of the dock-yard instructs ‘the students in the principles on which ships of war are built, and in the mode of putting the several parts to ether; making masts, and all other branches of naval architec¬ ture, by attending them one day in the week, during the six summer months, through the dock-yards. The gunner of marine artillery also instructs them in the practical knowledge of gunnery, and in the use of the firelock. The number of scholars, by the order in council of February 1806, was increased from forty to seventy: of these, thirty might be indiscriminately sons of officers, noblemen, or gentlemen ; but forty were invariably to be sons of commissioned officers in the naval service. None are admitted under thirteen, nor above sixteen years of age; and those are preferred to fill vacancies who have been previously at sea, provided they are of the proper age. No student can remain at the academy longer than three years; and the whole period of his residence is to be reckoned as two of the six years which it is necessary for a midshipman to serve before he can obtain a lieuten¬ ant’s commission. Each student, while actually at the academy, that is, during three hundred and thirty days in the year, receives four shillings daily; out of which he pays L.8 annually to the professor. The annual expense of the establishment, as fixed by the order in council of 1806, is about L.6363. In order to secure to the country the services of the students in that line for which they have been educated, the parents of all of them, except such as have been previously at sea, grant a bond of L.200, which is for¬ feited in case they do not enter into the naval service. The first year they are at sea, they are rated as vo¬ lunteers, on able searnaris pay; the second year, they have the rank and pay of midshipmen. They are direct¬ ed to keep journals, to draw head-lands, &c.; and when the ship comes into port, they are to attend the professor, who is to inspect their journals, and examine them regard¬ ing their advancement in the theoretical and practical knowledge of this profession. This academy, as established by the order in council already mentioned, was confined entirely to the education of young cadets for the navy: but in the third report of the commissioners, appointed to inquire into the civil affairs of the navy, laid before Parliament in June 1806, a regular system of education for shipwrights was also proposed; and the suggestion was accordingly carried into effect, though not till some years afterwards. The professor of the naval academy is also the instructor of the shipwright apprentices, but his instructions extend only to that class who are to serve on board his Majesty’s ships of war. No apprentice can be admitted to the aca¬ demy under sixteen years of age; and he must be pre¬ viously examined by the professor, before a committee of the navy board, in arithmetic, the first six books of Eu¬ clid, and in French. If the candidate is approved, he must be bound to the resident commissioner of the dock¬ yard for seven years, six of which he spends at the aca¬ demy, and one at sea. The salary of the apprentices in- Acadet creases yearly, from L.60 to L.140; out of which theyv-^v pay L.8 to the professor. The number of these appren¬ tices was originally limited to twenty-five; but latterly, six more have been added. They spend half the day un¬ der the professor; and the other half under the master shipwright, in the mould lofts, learning the management of timber, and manual labour in ship-building. Lectures are delivered three times a week, after working hours, on the branches of science connected with naval architec¬ ture ; and annual examinations take place before the re¬ sident commissioner, the master shipwright, and the pro¬ fessor. Out of the class of shipwright apprentices thus educat¬ ed, are selected the master measurers, foremen of ship¬ wrights, master boat-builders, master mast-makers, assist¬ ants to master ship-builders, mechanists in office of in¬ spector-general of naval works, assistants to surveyors of the navy, master shipwrights, second surveyor of navy, inspector-general of navy works, and first surveyor of navy. II. The Royal Military Academy at Woolwich was es¬ tablished by George II. by warrants dated 30th of April and 18th November 1741, for the purpose of instructing “ raw and inexperienced people belonging to the military branch of the ordnance, in the several parts of the mathe¬ matics necessary for the service of the artillery, and the business of engineers.” We find no further notice re¬ specting this institution till the year 1776, when the num¬ ber of scholars, then called cadets, amounted to forty- eight. In the year 1786, they were increased to sixty; in 1796, to ninety; and in 1798, to one hundred, forty of whom were educated for the service of the East India Company. This number continued till the year 1806, when the establishment was improved and further ex¬ tended, the number of masters being increased, and the cadets being divided into two bodies. This latter regula¬ tion took place in consequence principally of the unhealthy and confined situation of the old buildings in the royal arsenal; new buildings having been erected on Woolwich Common, on the side of Shooter’s Hill, in a more open and dry situation. As soon as these were finished, one hundred and twenty-eight cadets were lodged in them; sixty still continuing in the royal arsenal. At this period, there were nine masters of mathematics. In 1810, the cadets for the service of the East India Company were withdrawn from Woolwich; and the extra cadets, who, for want of room, had been sent to Marlow, or to private schools, were taken into the college, under the name of supernumeraries. The establishment at present consists of two hundred cadets, one hundred and twenty-eight of whom are in the new buildings, and seventy-two, includ¬ ing twelve supernumeraries, reside in the arsenal. The number of cadets is not fixed by warrant, but is at the discretion of the master-general of ordnance, who, with the board of ordnance, have the entire superintendence of the institution. The immediate direction, however, is vested in the lieutenant-governor and inspector, who are chosen generally from the artillery or engineers by the master-general of the ordnance. It is the duty of these officers, aided by the assistant inspector, to control the masters and professors, and to see that the cadets are taught the necessary branches of instruction. The pro¬ fessors and masters are appointed on the recommendation ot the lieutenant-governor, who, assisted by men of science, previously examines them. One master is appointed for every sixteen cadets. At present there are a professor of fortification, with two assistants ; a professor of mathema¬ tics, with six masters and assistants ; two French masters; ACADEMY. 79 tjemv.a drawing-master for ground, and an assistant; a drawing- ' / master for figures, and another for landscape ; a dancing- master ; a fencing-master; two modellers ; and a lecturer on chemistry. Lectures are also given on the different branches of natural philosophy. The inferior branches of education are taught at the lower institution in the arse¬ nal, and the higher branches at the buildings on the com¬ mon. The young men educated at the Royal Military Aca¬ demy of Woolwich are the sons of noblemen, gentlemen, or military officers. They are called gentlemen cadets, and cannot be admitted under fourteen, nor above sixteen years of age. They are nominated by the master-general of the ordnance, as governor of the academy; but they must be well grounded in English grammar, -arithmetic, and French ; and they undergo a previous public exami¬ nation before the masters of the academy. The cadets educated at Woolwich are considered as the first company of the royal regiment of artillery, of which the master-ge¬ neral of the ordnance is the captain. They are also divided into companies, each company having a captain and two subalterns, as military directors. Each cadet receives 2s. 6d. a day, or L.45. 12s. 6d. a year, which covers all his regular expenses, except keeping up his linen. The annual vacations consist of twelve weeks. Monthly returns of the studies of the cadets, showing the relative progress of each in every branch, with his particular character subjoined, are sent to the master- general of the ordnance: there are also public examina¬ tions before the general officers of the ordnance corps. Commissions are given to the cadets according to the report of their merits and acquirements ; they have their choice of entering either into the artillery or engineers. The whole expense to government, of the Royal Military Academy at Woolwich, is at the rate of about L.100 for each cadet. III. The Royal Military College, which is at present established at Farnham, in Surrey, and at Sandhurst, near Bagshot, was originally settled at High Wycombe and Great Marlow. • The establishment at High Wycombe commenced in January 1799, at which time there was a superintendent, commandant, two or three professors, and thirty-four students. Next year four more professors were added; and in 1801 it took the name of the Royal Military College by warrant of George III. A supreme board of commissioners, to superintend and regulate its concerns, was appointed, consisting of the commander-in- chief, secretary of war, and the heads of the great mili¬ tary departments, with others of high rank in the army ; three of whom, including the secretary of war, and the adjutant or quartermaster-general, were to form a board of management. By his Majesty’s warrant, dated the 4th of June 1802, another department, called the Junior De¬ partment of the Royal Military College, was formed; and the objects of this, as well as of the original, or Senior Department, were specifically pointed out. A collegiate board was also established, for the internal government of the college, consisting of the governor, lieutenant-go¬ vernor, and the commandants of the two departments. The last warrant relating to this establishment is dated 27th May 1808. It places both the departments, form¬ ing one college, under the command of the governor and lieutenant-governor; it continues the collegiate board; and it vests the appointment of professors and masters, after public notice of vacancies, and the examination of the candidates in the presence of the collegiate board, in the supreme board. By these warrants it was declared, that the Junior Department of the Institution, which was then at Marlow, was principally intended for those who w’ere destined for Academy, the military profession, in order to ground them in thev-^v^*-^ necessary sciences by the time they could hold commis¬ sions ; and also to afford provision for the orphan sons of meritorious officers, who had fallen or been disabled in the service of their country, or whose pecuniary circumstances rendered them unable to educate their sons properly for a military life. The warrant of 1808 fixed the number of students in the Junior Department at four hundred and twelve, divided into four companies of a hundred and three cadets each. They are admitted upon three differ¬ ent establishments:—1. Orphan sons of officers of the army or navy, who have fallen, died, or been disabled in the service: these are admitted free of expense, except that they are to bring the first suit of uniform on their admission, and to keep up their stock of linen, during their residence at the college. 2. The sons of officers actually serving in the army or navy, who pay a certain sum annually, from L.10 to L.60, according to the rank of their fathers. 3. The sons of noblemen and gentlemen, who pay L.100 per annum each. The military branch of the establishment attached to the Junior Department, consists of a commandant, a major, three captains, an adjutant, and inferior officers. The studies pursued in this department are, mathema¬ tics, natural philosophy, history, geography, fortification, military drawing, landscape drawing, arithmetic, classics, French, German, fencing, and writing. There are seven masters of mathematics, four of fortification, five of mili¬ tary drawing, three of landscape drawing, four of history, geography, and classics, six of French, one of German, and three of fencing. The course for this department lasts from three and a half to four years. Applications for admission must be made to the com¬ mander-in-chief, through the governor of the college, and his Majesty’s approbation obtained. Every candidate, previously to admission into the Junior Department, must pass an examination in Latin and English grammar, and in the first four rules of arithmetic ; and no candidate can be admitted under thirteen or above fifteen years of age. Examinations are held monthly, which are conducted by the professors of the Senior Department, for the pur¬ pose of ascertaining the progress of each cadet, previously to his removal from one class to another. There are also half-yearly examinations, in presence of the collegiate board, on which occasion one or more members of the supreme board, not being members of the collegiate board, attend. These examinations are held previously to the cadets’ receiving commissions from the college; and if they acquit themselves well, they are furnished by the board of commissioners, in whose presence the examina¬ tion takes place, with certificates of qualification to serve in the army as officers. The third class, or gentlemen cadets, are allowed to purchase commissions at any time during their continuance at the college ; but no gentle¬ man cadet can be recommended for a commission by pri¬ vate interest, until he has made a certain progress in his studies. The Senior Department of the Royal Military College, which was originally established at High Wycombe, is in¬ tended for the purpose of instructing officers in the scien¬ tific parts of their profession, with a view of enabling them better to discharge their duty when acting in the command of regiments ; and, at the same time, of qualify¬ ing them for being employed in the quartermaster’s and adjutant-general’s department. The military branch of the establishment of the Senior Department consists of a commandant and adjutant. The studies pursued are, mathematics in all their various branches, fortification, 80 A C A Academy gunnery, castrametation, military drawing and surveying, . ^^ the reconnoitring of ground, the disposition and move- /J^^ment of troops under all the various circumstances of de¬ fensive and offensive war, rules for estimating the mili¬ tary resources of a country, and the German and French languages. There are six professors in this department; one for mathematics, one for fortification, two for military drawing, one for French, and one for German. The full completnent of the Senior Department consists of thirty students. No officer can be admitted till he has completed the twenty-first year of his age, and actually served with his regiment, as a commissioned officer, three years abroad, or four years at home. Applications for ad¬ mission must be made to the governor, through the com¬ manding officer of the regiment to which the candidate belongs; and the governor transmits the application to the commander-in-chief, for his Majesty’s approbation. Such examination as may be deemed requisite, is required pre¬ viously to admission. Each student of this department pays into the funds of the college thirty guineas annually ; and after a certain period he is obliged to keep a horse, for the purpose of receiving such instruction as is given in the field. Therfe are public examinations half-yearly, conducted on the same principle as the half-yearly exa¬ minations of the Junior Department. Such officers as A C A have gone through the regular course of studies, and have Acadi passed this examination with credit, receive certificates ||] that they are duly qualified for staff-appointments, signed Acai by the board who examined them, and sealed with the'v>^v seal of the college. Officers or students of the first department, non-com¬ missioned officers, and other military persons belonging to the college, as well as the gentlemen cadets of the junior department, are subject to the articles of war; for which reason the latter are placed on the establishment of the army, and receive 2s. 6d. per day. This money contri¬ butes towards the expense of their education. The gentlemen cadets wear military uniforms. The general staff of the college consists of the gover¬ nor, the lieutenant-governor, the inspector-general of in¬ struction, and the chaplain, who, besides performing divine service, teaches the evidences and principles of Christian¬ ity. The rest of the staff are exclusively occupied with the finances of the college. In 1801, five hundred acres of land were purchased at Sandhurst, near Bagshot; and on this space large and commodious buildings were erected, into which the Junior Department was removed from Great Marlow; but the Senior Department remained at Farnham, which is at no great distance from Sandhurst. Academy Figure, a drawing of a naked man or woman, taken from the life; which is usually done on paper with red or black chalk, and sometimes with pastils or crayons. AC ADIE, or Ac Any, in Geography, a name formerly given to Nova Scotia, or New Scotland, in America. ACADNA, in antiquity, a Grecian measure of length, being a ten feet rod, used in measuring their lands. AC AM ANTIS, the ancient name of the island of Cy¬ prus, taken from one of its promontories situated to the west, and called Mania?. Teos in Ionia was also called thus from Acamas the founder. _ ACAMAS, son of Theseus, followed the rest of the Gre¬ cian princes to the siege of Troy; and was deputed, with Diomedes, to the TrojanS, in order to get Helen restored. Laodice, Priam’s daughtfer, fell in love with, and had a son by him, called Munitus. He was one of the heroes who concealed themselves in the wooden horse. One of the tribes of Athens was called Acamantides from him, by the appointment of the! oracle; and he founded a city in Phrygia Major, called Acamantium. Homer men¬ tions two other heroes of this name: one a Thracian prince, who came to succour Priam; another a son of Antenor. ACANGIS, that is, Ravdc/ers or Adventurers; a name which the Turks give their hussars or light troops, who are generally sent out in detachments to procure intelli¬ gence, harass the enemy, or ravage the country. ACANTHA, in Botany, the prickle of any plant: in Zoology, a term for the lupine or prickly fins of fishes. ACANTHABOLUS, in Surgery, an instrument for pulling thorns, or the like, out of the skin. ACANTHINE, any thing resembling or belonging to the herb acanthus. Acglithine garments, among the an¬ cients, are said to be mdde df the down of thistles ; others think they were garments embroidered in imitation of the acanthus.

ACAPULCO, a considerable town and port in Mexico, on a bay of the South Sea, distant from the city of Mexi¬ co south-east 210 miles. It has a remarkably fine har¬ bour, from whence a ship annually sails to Manilla in the Philippine islands in Asia; and another returns annually from thence with all the treasures of the East Indies, such as diamonds, rubies, sapphires, and other precious stones; the rich carpets of Persia; the camphire of Bor¬ neo ; the benjamin and ivory of Pegu and Cambodia; the silks, muslins, and calicoes, of the Mogul’s country; the gold dust, tea, china ware, silk, and cabinets, of China and Japan ; besides cinnamon, cloves, mace, nutmegs, and pepper; insomuch that this single ship contains more riches than many whole fleets. The goods brought to Acapulco are carried to the city of Mexico by mules and pack-horses. Acapulco is but a small place, containing about 4000 inhabitants, mostly people of colour; who are increased to 9000 by the resort of strangers to the annual fair, held wdien the Manilla galleon arrives. A wretched fort, with 31 pieces of cannon, defends the har¬ bour, which is equally extensive, safe, and commodious. Ihe basin which constitutes this harbour is surrounded by lolty mountains, which are so dry that they are even destitute of water, dhe air here is hot, heavy, and un¬ wholesome ; to which none can habituate themselves ex¬ cept certain negroes that are born under a similar climate, or some mulattoes. Upon the arrival of the galleons, traders flock hither from all the provinces of Mexico. The value of the precious metals exported in the galleon amounts in general to about L.200,000 or L.250,000, the value of the goods to about L.300,000 or L.400,000, ac¬ cording to Humboldt.

ACASTUS, in classic history, the son of Pelias, king of Thessaly, and one of the most famous hunters of the time, married Hippolita, who falling desperately in love with Peleus her son-in-law, and he refusing to gratify her wishes, she accused him to her husband of a rape; on which he slew them both. ACATALECTIC, a term in ancient poetry for such verses as have all their feet or syllables, in contradistinc¬ tion to those that have a syllable too few. The first verse of the two following from Horace is acatalectic or com¬ plete, the last catalectic or deficient. Solvitur acris hiems grata vice veris et Favoni, Trahuntque siccas machinee carinas. ACATALEPSY signifies the impossibility of compre¬ hending something. The distinguishing tenet of the Pyr- rhonists was their asserting an absolute acatalepsy in re¬ gard to every thing. ACATERY, or Accatry, anciently an officer of the king’s household, designed for a check betwixt the clerks of the kitchen and the purveyors.

ACATHISTUS, the name of a solemn hymn or vigil, anciently sung in the Greek church on the Saturday of the fifth week of Lent, in honour of the Virgin, for having thrice delivered Constantinople from the invasions of the barbarous nations. It was denominated uxudiisros, i. e. without sitting, because, in the celebration of the praises of the Virgin, the people stood all night singing. ACATlUM, in Ancient Navigation, a kind of boat or pinnace used for military purposes. The acatium was a species of those vessels called naves actuarice, i. e. such as were wrought with oars. It was sometimes made use of in battle. Strabo describes it as a privateer or pirate sloop, and Suidas as a fishing vessel.

ACCEDAS ad curiam, in English Law, a writ used where a man has received, or fears, false judgment in an inferior court. It lies also for justice delayed, and is a species of the writ Recordare. ACCELERATION, in Natural Philosophy, denotes generally an increase of motion or velocity, and is chiefly applied to the motion of such bodies as go on, not with a uniform motion, but one which becomes continually quick¬ er and quicker as they advance. A body, for example, roll¬ ing down a hill proceeds slowly at first, but gradually in¬ creases as it descends, until at last it acquires a velocity and momentum which bears down every thing before it. The same thing takes place when a body is dropped, and allowed to fall freely in the air; although the acceleration is here less observable, on account of the great rapidity of the de¬ scent. The earth, in its annual motion round the sun, is subject to a continued acceleration from the apogee to the perigee, while from thence again it suffers a similar retardation. Many other examples occur of such ac¬ celeration ; but the most interesting is the Acceleration of Falling Bodies. That such an acceleration does take place, is obvious from many circumstances, particu¬ larly the increasing momentum which a body acquires in proportion to the height of its descent. But it was only by considering the cause of the descent that the true law of the acceleration was determined. This great discovery we owe to the genius of Galileo. Various theories had been framed by philosophers to account for the accele¬ rated descent of falling bodies, but all of them incon¬ clusive and visionary. Some, for instance, ascribed it to the weight of the pure air above increasing as the body descended. The followers of Gassendi pretended that there are continually issuing out of the earth certain attractive corpuscles directed in an infinite number of rays; those, say they, ascend and then descend in such a manner, that the nearer a body approaches to the earth’s centre, the more of these attractive rays press upon it, in consequence of which its motion becomes accelerated. The Cartesians again ascribed the effect to the reiterated impulses of their materia suhtilis acting continually on falling bodies, and propelling them downwards. It ap¬ pears now incredible how such dreams could have been gravely proposed by men having the reputation of philoso¬ phers. Galileo, however, on considering the subject at¬ tentively, and applying the powerful aids of geometry and mathematics, soon discovered that the true cause was simply the continued action of the moving force of gravi¬ ty. This force, Galileo reasoned, must operate continu¬ ally on the body, not only at the moment of starting, but also during every moment of its descent. And as the body retains and accumulates all these impressions ac¬ cording to the great and original law of moving bodies, no wonder that its motion should become continually accelerated: for, suppose that gravity were to act only at certain small intervals, each second for instance, and suppose that at first it communicates such a mo¬ tion to the body as causes it to descend, say ten feet in the first second; the body could not stop here even though gravity were ceasing altogether to act on it: retaining the original impression, it would still go on moving uniformly at the rate of ten feet every second of its descent; but at the end of the first second, gravity B 82 ACC Accelera- again acts on it and communicates a second impression, by tion. virtue of which it would descend ten feet during the se¬ cond interval, in addition to the ten feet arising from the original impulse ; so that on the whole it descends 20 feet in the second interval. In the same manner, during the third interval it would descend 30 feet, and during the fourth 40, and so on ; the space described in each second thus increasing regularly with the increase of the time. Hence Galileo deduced the fundamental law of acce¬ leration in falling bodies, that the Velocity, which in every case is just the space described in each second or other fixed interval, increases in exact proportion to the whole time of descent; so that whatever be the ve¬ locity at the end of the first second, then at the end of any number of seconds the velocity would just be as many times greater,—a law from which he easily deduced all the others regarding the descent of falling bodies, which are of so much importance in mechanical inquiries. The most remarkable is that which regards the Space1 described, or the total amount of the descent in a given time. This Galileo deduced very elegantly from a simple geometrical consideration. In every case of a body moving uniformly without acceleration, the space describ¬ ed in any given time must be proportional to the time, and must be found by multiplying the time by the velo¬ city : it may be represented, therefore, by a simple dia¬ gram. Let A B,for instance, de¬ note by its length the velocity of the body, or the number of feet described by it in a second, and CD the time or number of se¬ conds during which it is in motion; then, if we construct a rectangle a E, of which one of the sides, a b, is equal to A B, and the other, c d, equal to C D, t this rectangle, that is, the number of square feet in it, will denote the space, that is, the number of lineal feet described during the- whole period. Let us now apply this principle to the case of a body moving with an accelerated velocity, and let AB, CD, EF, &c. denote the velocities at the end of certain equal intervals of time, of which let each be denoted by l m ; and _ suppose also, that during each of these inter¬ vals the motion is uniform, and is only accelerated by a sort of start which takes place at the end of each : then, if we construct a rectangle a l b, of which a b is, equal to A B, the velo¬ city at the end of the first interval, and a l equal to l m the first interval, this rectangle will denote the space de¬ scribed during that interval. Continue now the line a / to m, making lm — a l ■=. I m, and continue also l c to d, so that l d may be equal to D C, the velocity during the second interval, and complete the rectangle dime, this will denote the space de¬ scribed in the second in¬ terval ; and, in the same manner, each of the D- ■B —D -F -H K succeeding rectangles in descending will denote the space described in l Q_d e 1 ACC the succeeding interval, so that the total amount of the Aecelera. descent will be denoted by the sum of all the rectangles together, or by the compound figure which they form.^^^ But what is the nature of this figure ? It is evidently, as appears more clearly by taking out the parallel lines, triangular, only that the longest side presents a ser¬ rated outline. What is the cause of this ? It is clearly owing to the supposition we have made of the motion continuing uniform during the intervals, and then in¬ creasing by starts; instead of growing continually, as it really does. Suppose then that we shorten the intervals one-half, for instance, and double their number, we shall then be much nearer the truth ; but the inequa¬ lities in the hypothenuse of the triangle are now great¬ ly reduced ; and the more we thus diminish the intervals, and increase their num¬ ber, the more nearly does it approach to a straight line. In the extreme case, therefore, where there are in re¬ ality no intervals, but where the velocity goes on con¬ tinually increasing, neither will there be any inequalities in the outline; the figure will be really a triangle : and while the vertical side A B denotes the time of descent, and the horizontal B C the velocity, the area of the triangle will denote in square measure the space descended in the given time. But the areas of similar triangles are in every case proportional to the squares of their corresponding sides; that is, the area A B C is to A D E as the square of A B or B C is to the square of A D or D E. Hence in general it follows, that the spaces de¬ scribed in any given time or times are always pro¬ portional to the squares of these times, and also to the squares of the velocities at the end of such times. Thus, if a body describes 16 feet during the first second of its descent, it will, during the next, descend 4 times as much, or 64; during the third 9 times, or 144 feet; during the fourth 16 times, or 256, and so on. Such, then, is the great law of acceleration in re¬ gard to the spaces described. It is easily deducible also from numerical or algebraical considerations. Let the velocity, for example, at the end of any given time, such as a second, be denoted by 1; then in the se¬ cond, third, and fourth, it will be 2, 3, 4, &c. But the space described at the end of any time is evi¬ dently equal to the time multiplied by the mean velo¬ city; that is, the velocity at the half-interval. During the first second, therefore, the space described will be -i, during the second §, during the third f, during n -- o ^ the fourth and so on; adding these successively, the whole space from the beginning at the end of each in¬ terval will be f, 1£, &c., being each proportional to the square of the time. Algebraically again, if we suppose gravity to act only at the end of successive intervals, and the motion to continue uniform during these, then the spaces described will form an arithmetical progression, such as a, 2 a, 3 a, 4 a, 5 a, &c. ... n a, and the whole space will be the sum of this series, or a + ?J« X ^ ;= ' hnu v iui* lo 3dr ji oSijfinjsnQtS tofhf ——’——■ 1 This phrase, we may remark, probablv from Galileo’s geometrical illustration, has been rather aukwardly introduced in these discussions, and in a way which tends to produce a little obscurity.

In every view, then, this great law is established; and when we come to try it experimentally, which is done by means of Atwood’s machine, it is confirmed by the nicest observation; every falling body describing in the first second 16-^ feet, and in every other a space propor¬ tional to the time. See Atwoods Machine, Dynamics, Mechanics, &c. (c.) Acceleration, in Astronomy, is applied in various ways, and to different objects. Thus, the Acceleration of the Fixed Stars denotes that apparent increase of motion or velocity by which night after night they arrive sooner and sooner upon the meridian than before. A star which passes the meridian to-night at 10 o’clock, for instance, will to-morrow night arrive at it 3' 56" sooner, or at 56' 4" past nine, and so on each succeeding evening; thus anticipating continually the niQtion of the sun, which regulates the length of the day. A star which passes the meridian to-day with the sun, will to-morrow pass 3' 56" sooner; so that it appears to revolve with a quicker or accelerated motion. It is in reality the sun, however, moving continually backwards among the stars which causes in them this apparent acceleration. Acceleration of the Planets denotes that accelerated mo¬ tion with which they all, as well as the earth, advance from the perigee to the apogee of their orbits. This acceleration is most readily observed by comparing the successive diur¬ nal motions of the planet in its orbit. When the actual diurnal motion exceeds the mean diurnal motion, the planet is accelerated ; and, on the other hand, when it falls short of it, it is retarded, as takes place between the apogee and perigee. Acceleration of the Moon is a remarkable increase which has been discovered in the moon’s motion in her orbit, which has been going on increasing from age to age by a gradation so imperceptible, that it was only discovered or suspected by Dr Halley, on comparing the ancient eclipses observed at Babylon and others with those of his own time. The quantity of this acceleration was afterwards determined by Mr Dunthorne from more accurate data regarding the longitudes of Alexandria and Babylon, and from the most authentic eclipse of which any good ac¬ count remains, observed at Babylon in the year 721 be¬ fore Christ. The beginning of this eclipse, as observed at that time, was about an hour and three quarters sooner than he found it would have been by computation; and hence he found the mean acceleration, or what has since been termed the moon’s secular equation, about 10" of a de¬ gree each century. According to Laplace, it amounts to 11*135". This remarkable fact had long excited the atten¬ tion of astronomers; as, along with several others of the same kind among the heavenly bodies, it seemed to betray imperfection; exhibiting inequalities which were contin¬ ually increasing, instead of correcting themselves or being somehow compensated by that admirable design which prevailed in every other part of the system. At last, how¬ ever, it was discovered, by the application of a refined analysis, that these inequalities were not perpetual; that they actually terminate in the lapse of ages, and again return in the opposite direction, thus preserving entire tire harmony of the celestial motions. This fine discovery, which observation alone could never have disclosed, we owe to the genius of Laplace. See Astronomy in this work; also Phil. Tram.

ACCENDENTES, alower order of ministers in the Ro¬ mish church, whose office is to light and trim the candles. ACCENDONES, in Roman antiquity, a kind of gladi¬ ators, whose office was to excite and animate the com¬ batants during the engagement. The orthography of the word is contested: the first edition of Tertullian, by Rhenanus, has it accedones ; an ancient manuscript, accen- dones. Aquinas adheres to the former, Pitiscus to the latter. The origin of the word, supposing it accendones, is from accendo, I kindle ; supposing it accedones, from accedo, I accede, am added to. The former places their distin¬ guishing character in enlivening the combat by their ex¬ hortations and suggestions: the latter supposes them to be much the same with what among us are called seconds, among the Italians, patroni; excepting that these latter only stand by to see the laws of the sword duly observed, without intermeddling to give advice or instruction. ACCENSI, in the Roman armies, certain supernumer¬ ary soldiers, designed to supply the place of those who should be killed or anywise disabled. They were thus denominated, quia accensebantur, or ad censum adjicieban- tur. Vegetius calls them supernumerarii legionum. Cato calls them ferentarii, in regard they furnished those en¬ gaged in battle with weapons, drink, &c. Nonnius sug¬ gests another reason of that appellation, viz. because they fought with stones, slings, and weapons, quce feruntur, such as are thrown, not carried in the hand. They were sometimes also called velites, and velati, because they fought clothed, but not in armour ; sometimes adscriptitii, and adscriptivi; sometimes rorarii. The accensi, Livy observes, were placed in the rear of the army, because little was expected from them: they were taken out of the fifth class of citizens. Accensi, in antiquity, denotes ah inferior order of officers, appointed to attend the Roman magistrates, some¬ what in the manner of ushers, serjeants, or tipstaves among us. They were thus called from accire, to send for ; one part of their office being to call assemblies of the people, summon parties to appear and answer before the judges, &c. Accensi was also an appellation given to a kind of ad¬ jutants, appointed by the tribune to assist each centurion and decurion ; in which sense accensus is synonymous with optio. In an ancient inscription, given by Torre, we meet with Accensus Equitum Romanorum ; an office no¬ where else heard of. That author suspects it for a cor¬ ruption ; and instead thereof reads, A Censibus. ACCENSION, the action of setting a body on fire: thus the accension of tinder is effected by striking fire with flint gnd steel. ACCENT, in reading or speaking, an inflection of the voice, which gives to each syllable of a word its due pitch in respect of height or lowness. See Reading. The word is originally Latin, accentus ; a compound of ad, to, and cano, to sing. Accentus quasi adcantus, or juxta can- turn. In this sense, accent is synonymous with the Greek rows; the Latin tenor, or tonor; and the Hebrew oim, gustus, taste. Accent, among grammarians, is a certain mark or ACCENT. 84 Accent, character placed over a syllable to direct the stress of its pronunciation. We generally reckon three grammatical accents in ordinary use, all borrowed from the Greeks, viz. the acute accent ('), which shows when the tone of the voice is to be raised; the grave accent (v), when the note or tone of the voice is to be depressed; and the circum¬ flex accent (A), which is composed of both the acute and the grave, and points out a kind of undulation of the voice. The Latins have made the same use as the Greeks of these three accents. The Hebrews have a grammatical, a rhetorical, and a musical accent; though the first and last seem, in effect, to be the same, both being comprised under the general name of tonic accents, because they give the proper tones to syllables; as the rhetorical accents are said to be euphonic, because they tend to make the pronunciation more sweet and agreeable. There are four euphonic ac¬ cents, and twenty-five tonic: of these some are placed above, and others below the syllables; the Hebrew accents serving not only to regulate the risings and fallings of the voice, but also to distinguish the sections, periods, and members of periods, in a discourse, and to answer the same pur¬ poses with the points in other languages. Their accents are divided into emperors, kings, dukes, &c. each bearing a title answerable to the importance of the distinction it makes. Their emperor rules over a whole phrase, and terminates the sense completely ; answering to our point. Their king answers to our colon; and their duke to our comma. The king, however, occasionally becomes a duke, and the duke a king, as the phrases are more or less short. It must be noted, by the way, that the management and combination of these accents in Hebrew poetry differ from their management and combination in prose. The use of the tonic or grammatical accents has been much contro¬ verted ; some holding that they distinguish the sense, while others maintain that they are only intended to re¬ gulate the music or singing, alleging that the Jews sing 1 Cooper, rather than read the Scriptures in their synagogues.1 Be Dom. Mo- this, however, as it will, it is certain the ancient Hebrews saic. Clav. were not acquainted with these accents. The opinion V' 31* which prevails amongst the learned is, that they were invented about the sixth century, by the Jewish doctors of the school of Tiberias, called the Massorets. As to the Greek accents, now seen both in manuscripts and printed books, there has been no less dispute about their antiquity and use than about those of the Hebrews. Isaac Vossius endeavours to prove them of modern inven¬ tion ; asserting, that anciently they had nothing of this kind, but only a few notes in their poetry, which were invented by Aristophanes the grammarian, about the time of Ptolemy Philopater; and that these were of musical rather than grammatical use, serving as aids in the sing¬ ing of their poems, and being very different from those af¬ terwards introduced. He also shows, from several ancient grammarians, that the manner of writing the Greek accents in those days was quite different from that which appears in our books. The author of La Methode Grecque, p.546, observes, that the right pronunciat ion of the Greek language being natural to the Greeks, it was need¬ less for them to mark it by accents in their writings; so that, according to all appearance, they only began to make use of them about the time when the Romans, wishing to learn the Greek tongue, sent their children to study at Athens, thinking thereby to fix the pronuncia¬ tion, and to facilitate it to strangers; which happened, as the same author observes, a little before Cicero’s time. Wetstein, Greek professor at Basil, in a learned disserta¬ tion, endeavours to prove the Greek accents of an older standing. He owns that they were not always formed in the same manner by the ancients, but he thinks that differ- Accent, ence owing to the different pronunciation which obtained in the different parts of Greece. He also brings several reasons, a priori, for the use of accents, even in the earliest days : as, that all writing being then in capital letters equi¬ distant from each other, without any distinction either of \fords or phrases, it could scarcely have been rendered in¬ telligible without accents ; and that accents were necessary to distinguish ambiguous words, and to point out their proper meaning, as appears from a dispute in regard to a passage of Homer, mentioned by Aristotle in his Poetics, chap. v. Accordingly, he observes that the Syrians, vtdio have tonic, but not distinctive accents, have yet in¬ vented certain points, placed either below or above the words, to show their mood, tense, person, or sense. Mr Browne of Trinity College, Dublin, has entered more deeply into this investigation; and as he had an op¬ portunity of conversing with the crew of a Greek ship from Patras, a town situated not far distant from the an¬ cient Corinth, which had been driven by stress of weather into the port of Dingle in Ireland, the result of his in¬ quiries wa.s, that the practice of the modern Greeks is dif¬ ferent from any of the theories that have been delivered in books. “ It is true,” he observes, “ they have not two pro¬ nunciations for prose and for verse, and in both they read by accent; but they make accent the cause of quantity, they make it govern and control quantity, they make the syllable long on which the acute accent falls, and they allow the acute accent to change the real quantity. They always read poetry as well as prose by accent. Whether any inference can hence be drawn as to the pronunciation of the ancients, I must leave, after what I have premised above, to men of more learning; but I think it at least so probable as to make it worth while to mention the in¬ stances which occurred in proof of this assertion more particularly. Of the two first persons whom I met, one, the steward of the ship, an inhabitant of the island of Cephalonia, had had a school education: he read Euri¬ pides, and translated some easier passages, without much difficulty. By a stay in this country of near two years, he was able to speak English very tolerably, as could also the captain and several of the crew; and almost all of them spoke Italian fluently. The companion, however, of the stewarch could speak only modern Greek, in vrhich I could discover that he was giving a description of the distress in which the ship had been ; and though not able to under¬ stand the context, I could plainly distinguish many words, such as divdga, i^uXov, and among the rest the sound of Av6^umg pronounced short. This awoke my curiosity, which was still more heightened when I observed that he said Avdgurruv long, with the same attention to the alteration of the accent with the variety of case, which a boy would be taught to pay at a school in England. W’atching there¬ fore more closely, and asking the other to read some ancient Greek, I found that they both uniformly pro¬ nounced according to accent, without any attention to long or short syllables where accent came in the way ; and on their departure, one of them having bid me good day, by saying KuXrifiiga,, to which I answered KaXrigtga, he with strong marks of reprobation set me right, and repeat¬ ed Kahripiga; and with like censure did the captain upon another occasion observe upon my saying Socrates instead of Socrates. “ I now had a strong wish to know whether they ob¬ served the distinction in this respect usually between verse and prose ; but from the little scholarship of the two men with whom I had conversed, from the ignorance of a third whom I afterwards met, (who however read Lucian with ease, though he did not seem ever to have heard of ACCENT. 85 Aent. the book,) and on account of my imperfect mode of con- J versing with them all, I had little hopes of satisfaction on the point-; nor was I clear that they perfectly knew the difference between verse and prose. At length, having met with the commander of the ship, and his clerk Atha¬ nasius Kovo/iof, and finding that the latter had been a schoolmaster in the Morea, and had here learnt to speak English fluently, I put the question to them in the pre¬ sence of a very learned college friend, and at another time, to avoid any error, with the aid of a gentleman who is perfectly master of the Italian language. Both the Greeks repeatedly assured us that verse as well as prose was read by accent, and not by quantity; and exemplified it by reading several lines of Homer, with whose name they seemed perfectly well acquainted. “ I shall give an instance or two of their mode of reading; S’ kytim vugu S/to -ffoXuipXo/tfSo/o Sa'Xdffffvig, Tm 5’ ava/AtiQofuvos trgoatpri mdag uxvg ’A^iXXsug, 'Eg b' egirag Emrqbsg ayz/gofisv, eg b’ haro/iZriv.

Revertentem ex •provincia modulatis carmi- nibus prosequebantur, says Suetonius, who gives another instance in the time of Tiberius : a false report of Germa- nicus’s recovery being spread through Rome, the people ran in crowds to the Capitol with torches and victims, singing, Salva Roma, Salva Patria, Salvus est Germani- cus. Nero, passionately fond of music, took special care to improve and perfect the music of acclamations. Charm¬ ed with the harmony with which the Alexandrians, who came to the games celebrated at Naples, had sung his praises, he brought several over to instruct a number of youth, chosen from among the knights and people, in the different kinds of acclamations practised in Alexandria. These continued in use as long as the reign of Theodoric. But the people did not always make a single chorus; sometimes there were two, who answered each other al¬ ternately : thus, when Nero played in the theatre, Bur¬ rhus and Seneca, who were on either hand, giving the sig¬ nal by clapping, 5000 soldiers, called Augustals, began to chant his praise, which the spectators were obliged to re¬ peat. The whole was conducted by a music-master, call¬ ed mesoclwrus or pausarius. The honour of acclamations was chiefly rendered to emperors, their children, and fa¬ vourites; and to the magistrates who presided at the games. Persons of distinguished merit also sometimes received them, of which Quintilian gives us instances in Cato and Virgil. The most usual forms were, Feliciter, Longiorem vitam, Annos felices. The actors themselves, and they who gained the prizes in the games of the cir¬ cus, were not excluded the honour of acclamations. To theatrical acclamations may be added those of the soldiery and the people in time of triumph. The victo¬ rious army accompanied their general to the Capitol; and, among the verses they sung in his praises, frequently re¬ peated lo Triumphe, which the people answered in the same strain. It was also in the way of acclamation that the soldiers gave their general the title of Imperator, after some notable victory; a title which he only kept till the time of his triumph. The acclamations of the senate were somewhat more serious than the popular ones, but arose from the same principle, viz. a desire of pleasing the prince or his fa¬ vourites ; and aimed likewise at the same end, either to express the general approbation and zeal of the company, or to congratulate him on his victories, or to make him new protestations of fidelity. These acclamations were usually given after a report made by some senator, to which the rest all expressed their consent by crying, Om- nes, Omnes ; or else, ^Equum est, Justum est. Some¬ times they began with acclamations, and sometimes end¬ ed with them, without other debates. It was after this manner that all the elections and proclamations of empe¬ rors, made by the senate, were conducted; something of which practice is still retained at modern elections of kings and emperors, where Vivat Rex, and Long live the King, are customary forms of acclamation. The Greeks borrowed the custom of receiving their emperors in the public places from the Romans. Luit- prand relates, that at a procession where he was present, they sung to the Emperor Nicephorus, noKha irea ; that is, many years; which Coddin expresses thus, by ro ■^ujOsm to ‘TroXv^oviov, or by ro ; and the wish or salu¬ tation by wokvygovHJfjM. And at dinner, the Greeks then present wished with a loud voice to the emperor and Bar- das, Ut Deus annos multiplicet, as he translates the Greek. Plutarch mentions an acclamation so loud, upon occasion ACC of Flaminius’s restoring liberty to Greece, that the very Acclai birds fell from heaven with the shout. The Turks prac- tio tise something like this, on the sight of their emperors and grand viziers, to this day. -Accois For the acclamations with which authors, poets, &c.'^v were received, who recited their works in public ; it is to be observed, the assemblies for this purpose were held with great parade in the most solemn places, as the Ca¬ pitol, temples, the Athenaeum, and the houses of great men. The chief care was that the acclamations might be given with all the order and pomp possible. Men of fortune who pretended to wit, kept able applauders in their service, and lent them to their friends. Others en¬ deavoured to gain them by presents and treats. Philo- stratus mentions a young man named Vavus, who lent money to the men of letters, and forgave the interest to such as applauded his exercises. These acclamations were conducted much after the same manner as those in the theatre, both as to the music and the accompaniments : they were to be suited both to the subject and to the person. There wrere particular ones for the philosophers, for ora¬ tors, for historians, and for poets. It would be difficult to rehearse all the forms of them ; one of the most usual was Sophos, which was to be repeated three times. Martial comprehends several other usual forms in this verse: Graviter, Cito, Nequiter, Page, Reate. Neither the Greeks nor Romans were barren on this head. The names of gods and heroes were given to those whom they would extol. It was not enough to do it after each head of discourse, chiefly after the exordium; but the acclamations w'ere renewed at every fine passage, frequently at every period. The acclamations with which the spectators honoured the victories of the athletae, were a natural consequence of the impetuous motions which attended the gymnastic games. The cries and acclamations of the people, some¬ times expressing their compassion and joy, sometimes their horror and disgust, are strongly painted by different poets and orators. _ Acclamations made also a part of the ceremony of mar¬ riage. They were used for the omen’s sake, being the Lata Omina sometimes spoken of before marriage in Roman writers. Acclamations, at first practised in the theatre, and pass¬ ing thence to the senate, &c. were, in process of time, re¬ ceived into the acts of councils, and the ordinary assem¬ blies of the church. The people expressed their appro¬ bation of the preacher variously; the more usual forms were, Orthodox ! Third Apostle, &c. These acclamations being sometimes carried to excess, and often misplaced, were frequently prohibited by the ancient doctors, and at length abrogated; though they appear to have been in some use about the time of St Bernard. Acclamation Medals, among Antiquaries, such as re¬ present the people expressing their joy in the posture of acclamation. r r & . J ^ i ACCLIVITY, the rise or ascent of a hill, in opposition to the declivity or descent of it. Some writers on forti¬ fication use it for the talus of a rampart. ACCOLA, among the Romans, signified a person who lived near some place; in which sense it differed from incola, the inhabitant of such a place. ACCOLADE, a ceremony anciently used in the con¬ ferring of knighthood. Antiquaries are not agreed wherein the accolade pro*- perly consisted. The generality suppose it to be the embrace or kiss which princes anciently gave the new kmght, as a token of their affection; whence the word ACC A C C 89 I, colee accolade; q. d. a clasping, or taking round the neck.

His death took place in 1466. He wrote in Latin a treatise concerning the war which the Christians carried on against the infidels to recover Judea and the holy sepulchre. This work is the ground-plot of Tasso’s Jerusalem Delivered. It only includes, however, the history of the first crusade. He also wrote an ac¬ count of the Excellent Personages of his Time, in the form of a dialogue. Accolti, Francis, brother of Benedict, was born about the year 1418. He was professor of jurisprudence in Bologna, Ferrara, and some other universities. He died in 1483, leaving behind him several works on law, some translations from the Greek, and some poetical pieces. There is, in the Ambrosian library at Milan, a collection of his Letters, written in the Latin language. ACCOMMODATION, the application of one thing, by analogy, to another; or the making two or more things agree with one another. To know a thing by accommo¬ dation, is to know it by the idea of a similar thing referred thereto. A prophecy of Scripture is said to be fulfilled in various ways : properly, as when a thing foretold comes to pass ; and improperly, or by way of accommodation, when an event happens to any place or people, like to what fell out some time before to another. Thus, the words of Isaiah, spoken to those of his own time, are said to be fulfilled in those who lived in our Saviour’s, and are accommodated to them: “ Ye hypocrites, well did Esaias prophesy of you, &c.; which same words St Paul afterwards accommo¬ dates to the Jews of his time. . prinfitive church accommodated multitudes of Jew¬ ish, and even Heathen ceremonies and practices, to Chris¬ tian purposes ; but the Jews had before done the same by the Gentiles: some will even have circumcision, the tabernacle, brazen serpent, &c. to have been originally of Egyptian use, and only accommodated by Moses to tin? ■’P1’ Purposes ot Judaism.1 Speqcer maintains, that most of fill ‘ T' riMeS ot tlle ol4 law were in imitation of those of the r Gentiles, and particularly of the Egyptians ; that God, in order to divert the children of Israel from the worship they paid to their false deities, consecrated the greater part of the ceremonies performed by those idolaters, and ia formed out of them a body of the ceremonial law; lat he had indeed made some alterations therein, as barriers against idolatry; and that he thus accommodated his worship to the genius and occasions of his ancient people. To this condescension of God, according to vol. 11. • ® Accompaniment, in Painting, denotes such objects as are added, either by way of ornament or fitness, to the principal figures; as dogs, guns, game, &c* in a hunting piece. Accompaniment, in Heraldry, any thing added to a shield by way of ornament; as the belt, mantling, sup¬ porters, &c. It is also applied to several bearings about a principal one ; as a saltier, bend, fesse, chevron, &c. ACCOMPLICE, one that has a hand in a business, or is privy in the same design or crime with another. The Council of Sens, and the statutes of several other synods, expressly prohibit the revealing of accomplices. ACCOMPLISHMENT, the entire execution or ful¬ filling of any thing. Accomplishment is principally used in speaking of events foretold by the Jewish prophets in the Old Testa¬ ment, and fulfilled under the New. We say a literal ac¬ complishment, a mystical or spiritual accomplishment, a single accomplishment, a double accomplishment, a Jewish accomplishment, a Christian, a Heathen accomplishment. The same prophecy is sometimes accomplished in all or in several of those different ways. Thus, of some of the prophecies of the Old Testament, the Jews find a literal accomplishment in their own history, about the time when the prophecy was given; the Christians find another in Christ, or the earliest days of the church; the Heathens, another in some of their emperors; the Mahometans another in their legislator, &c. There are two principal ways of accomplishing a prophecy; directly, and by ac¬ commodation. See Accommodation, and Prophecy. ACCORD, in Painting, is the harmony that reigns' among the lights and shades of a picture. ACCORDS, Sieur des. See Tabourot, Stephen. ACCORSO (in Latin Accursius), Francis, an eminent lawyer, was born at Florence, according to some, in 1151, according to others, in 1182. He began the study of law at a late period of life; but such were his assiduity and proficiency, that he soon distinguished himself. He was appointed professor at Bologna, and became a very emi¬ nent teacher. He undertook the great work of uniting and arranging into one body the almost endless comments and remarks upon the Code, the Institutes, and Digests, which only tended to involve the subjects in obscurity and contradiction. When he was employed in this work, it is said that, hearing of a similar one proposed and begun by Odofred, another lawyer of Bologna, he feigned indis¬ position, interrupted his public lectures, and shut himself up, till he had, with the utmost expedition, accomplished M 0 90 A C C -Accorso his design. His work has the vague title of the Great II Gloss. The best edition of it is that of Godefroi, published Account. Lyons in 1589, in 6 vols. folio. Accursius was greatly extolled by the lawyers of the twelfth and thirteenth centuries, but those of the fourteenth and of the sixteenth formed a much lower estimate of his merits. There can be no doubt that he has disentangled with much skill the sense of many laws ; but it is equally undeniable that his ignorance of history and antiquities has often led him into absurdities, and been the cause of many detects in his explanations and commentaries. He is said to have lived in opulence, and to have died at Bologna in the seventy-eighth year of his age. His eldest son, Francis, who filled the chair of law at Bologna with great reputa¬ tion, was invited to Oxford by King Edward I., and in 1275 or 1276 read lectures on law in that university. In 1280 he returned to Bologna, where he died in 1321. Accorso, or kcc\msivs,Mariangelo,?L learned and inge¬ nious critic, was a native of Aquila, in the kingdom of Naples, and lived about the beginning of the sixteenth century. To a perfect knowledge of Greek and Latin he added an intimate acquaintance with several modern lan¬ guages. Classical literature was much improved and pro¬ moted by his labours. In discovering and collating an¬ cient manuscripts he displayed uncommon assiduity and diligence. His work entitled Diatribce in Ausonium, Solinum, et Ovidium, printed at Rome, in folio, in 1524, is a singular monument of erudition and critical skill. He bestowed, it is said, unusual pains on Claudian, and made above seven hundred corrections in the works of that poet, from different manuscripts. Unfortunately the world has been deprived of the advantage of these criti¬ cisms, for they were never published. An edition of Ammianus Marcellinus, which he published at Augsburg in 1533, contains five books more than any former one. He was the first editor of the Letters of Cassiodorus, with his Treatise on the Soul. The affected use of antiquated terms, introduced by some of the Latin writers of that age, is humorously ridiculed by him, in a dialogue published in 1531, entitled Osco, Volsco, Romanaque Lloquentia Interlocutoribus, Dialogus Ludis Romanis actus. It was republished at Rome in 1574, in 4to, with his name. He was also the author of a poem entitled Protrepticon ad Corynym, published in a scarce collection named Cary- ciana, printed at Rome in 1524. Accorso had been ac¬ cused of plagiarism in his notes on Ausonius; and the solemn and determined manner in which he repelled this charge of literary theft, presents us with a singular in¬ stance of his anxiety and care to preserve his literary re¬ putation unstained and pure. It is in the following oath : “ In the name of gods and men, of truth and sincerity, I solemnly swear, and if any declaration be more binding than an oath, I in that form declare, and I desire that my declaration may be received as strictly true, that I have never read or seen any author from which my own lucubrations have received the smallest assistance or im¬ provement ; nay, that I have even laboured, as far as pos¬ sible, whenever any writer has published any observations which I myself had before made, immediately to blot them out of my own works. If in this declaration I am for¬ sworn, may the pope punish my perjury; and may an evil genius attend my writings, so that whatever in them is good, or at least tolerable, may appear to the unskilful multitude exceedingly bad, and even to the learned trivial and contemptible; and may the small reputation I now possess be given to the winds, and regarded as the worth¬ less boon of vulgar levity.” ACCOUNT, or Accompt, in a general sense, a compu¬ tation or reckoning of any thing by numbers.—Collective- ACC ly, it is used to express the books which merchants, traders, Accoi bankers, &c. use for recording their transactions in business. an Chamber of Accounts, in the French polity, a sove- U reign court of great antiquity, which took cognizance of. t™ and registered the accounts of the king’s revenue ; nearly the same with the English Court of Exchequer. ACCOUNTANT, or Accomptant, in the most general sense, is a person skilled in accounts. In a more restrict¬ ed sense, it is applied to a person or officer appointed to keep the accounts of a public company or office; as the South Sea, the India Company, the Bank, the Excise, &c. ACCOUNTANT-general, a new officer in the court of chancery, appointed by act of parliament to receive all moneys lodged in court, instead of the masters, and con¬ vey the same to the bank of England for security. ACCRETION, in Physics, the increase or growth of an organical body, by the accession of new parts. Accretion, among civilians, the property acquired in a vague or unoccupied thing, by its adhering to or follow¬ ing another already occupied: thus, if a legacy be left to two persons, one of whom dies before the testator, the le¬ gacy devolves to the survivor by right of accretion. ACCROCHE, mHeraldry, denotes a thing’s being hook¬ ed with another. ACCUBATION, a posture of the body, between sitting and lying. The word comes from the Latin accubare, compounded of ad, to, and cubo, I lie down. Accubation, or Accubitus, was the table posture of the Greeks and Romans; whence we find the words particularly used for the lying, or rather (as we call it) sitting down to meat. The Greeks introduced this posture. The Romans, dur¬ ing the frugal ages of the republic, were strangers to it; but as'luxury got footing, this posture came to be adopt¬ ed, at least by the men; for as to women, it was re¬ puted an indecency in them to lie down among the men, though afterwards this too was got over. Children did not lie down, nor servants, nor soldiers, nor persons of meaner condition. They took their meals sitting, as a posture less indulgent. The Roman manner of disposing themselves at table was this:—A low round table was placed in the ccenaculum, or dining-room, and about this, usually three, sometimes only two, beds or couches; and, according to their number, it was called biclinium or tri¬ clinium. These were covered with a sort of bedclothes, richer or plainer, according to the quality of the person, and furnished with quilts and pillows, that the guests might lie the more commodiously. There were usually three persons on each bed; to crowd more was esteem¬ ed sordid. In eating, they lay down on their left sides, with their heads resting on the pillows, or rather on their elbows. The first lay at the head of the bed, with his feet extended behind the back of the second; the second lay with the back of his bead towards the navel of the first, only separated by a pillow, his feet behind the back of the third ; and so of the third or fourth. The middle place was esteemed the most honourable. Before they came to table, they changed their clothes, putting on what they called ccenatoria vestis, the dining garment; and pulled off their shoes, to prevent soiling the couch. ACCUBITOR, an ancient officer of the emperors of Constantinople, whose business was to lie near the empe¬ ror. He was the head of the youth of the bed-chamber, and had the cuhicularius and procubitor under him. ACCUMULATION, in a general sense, the act of heaping or amassing things together. Among lawyers it is used in speaking of the concurrence of several titles to the same thing, or of several circumstances to the same proof. AccumulA non of Degree^ in a uriircrsity, is the taking ACC A C ,K 91 ^cursed of several of theYn together, or at shorter intervals than II usual, or than is allowed by the rules of the university. • ccusa- ACCURSED; something that lies under a curse, or f sentence of excommunication.—In the Jewish idiom, ac- mrse(i an(j crucified were synonymous. Among them, every one was accounted accursed who died on a tree. This serves to explain the difficult passage in Rom. ix. 3, where the apostle Paul wished himself accursed after the nianner of Christ, i. e. crucified, if happily he might, by such a death, save his countrymen. The pre¬ position avo, here made use of, is used in the same sense, 2 Tim. i. 3, where it obviously signifies after the manner of. ACCUSATION, the charging of any person with a cri¬ minal action, either in one’s own name or in that of the public. The word is compounded of ad, to, and causari, to plead. Writers on politics treat of the benefit and the incon¬ veniences of public accusations. Various arguments are alleged both for the encouragement and discouragement of accusations against great men. Nothing, according to Machiavel, tends more to the preservation of a state than frequent accusations of persons intrusted with the admini¬ stration of public affairs. This, accordingly, was strictly observed by the Romans in the instance of Camillus, ac¬ cused of corruption by Manlius Capitolinus, &c. Accu¬ sations, however, in the judgment of the same author, are not more beneficial than calumnies are pernicious; which is also confirmed by the practice of the Romans. Man¬ lius, not being able to make good his charge against Ca¬ millus, was cast into prison. By the Roman law, there was no public accuser for public crimes; every private person, whether interested in the crime or not, might accuse, and prosecute the ac¬ cused to punishment or absolution. Cato, the most inno¬ cent person of his age, had been accused 42 times, and as often absolved. But the accusation of 'private crimes was never received but from the mouths of those who were immediately interested in them: None {e. g.) but the husband could accuse his wife of adultery. The ancient Roman lawyers distinguished between j»os- tulntio, delatio, and accusatio. For, first, leave was desired to bring a charge against one, which was called postulare: then he against whom the charge was laid was brought before the judge, which was called deferre, or nominis de¬ latio: lastly, the charge was drawn up and presented, which was properly the accusatio. The accusation pro¬ perly commenced, according to Pedianus, when the reus or party charged, being interrogated, denied he was guilty of the crime, and subscribed his name to the delatio made by his opponent. In Britain, by Magna Charta, no man shall be impri¬ soned or condemned on any accusation, without trial by his peers or the law; none shall be vexed with any accu¬ sation, but according to the law of the land; and no man shall be molested by petition to the king, &c. unless it be by indictment or presentment of lawful men, or by pro¬ cess at common law. Promoters of suggestions are to find surety to pursue them, and if they do not make them good, shall pay damages to the party accused, and also a fine to the king. No person is obliged to answer upon oath to a question whereby he may accuse himself of any crime. ACCUSATIVE, in Latin Grammar, is the fourth case of nouns, and signifies the relation of the noun on which the action implied in the verb terminates; and hence, in such languages as have cases, these nouns have a particu¬ lar termination, called accusative, as, Augustus vicit Anto- nium, Augustus vanquished Antony. Here Antonium is the noun on which the action implied in the word vicit terminates, and therefore must have the accusative ter¬ mination. Ovid, speaking of the palace of the sun, says, ACe Materiem superabat opus. The work surpassed the mate- || rials. Here materiem has the accusative termination, be- Acepha- cause it terminates the action of the verb superabat.—In ^ous‘ the English language there are no cases, except the geni-V^~v~Nk tive; the relation of the noun being shown by the assist¬ ance of prepositions, as of, to, from, &c. ACE, among gamesters, a card or die marked only with one point. ACELDAMA, in Scripture history, a place without the south wall of Jerusalem, beyond the brook of Siloam, which was called the Potter’s Field, because clay of which pots were made was dug out of it. It was afterwards bought with the money with which the high-priests and rulers of the Jews purchased the blood of Jesus Christ; and hence it was called Aceldama, the field of blood. ACENTETUM, or Acenteta, in Natural History, a name given by the ancients to the purest and finest kind of rock-crystal. They used the crystal in many ways; sometimes engraving on it, and sometimes forming it into vases and cups, which were held next in value to the vasa murrhina of those times. The crystal they obtained from the island of Cyprus was much esteemed, but often faulty in particular parts, having hairs, cracks, and foulnesses, which they called salts, in the middle of the large pieces. Pliny tells us, that when it was used for engraving on, the artist could conceal all these blemishes among the strokes of his work; but when it was to be formed into cups or precious vases, they always chose the Acentetum, which had no flaws or blemishes. ACEPHALI, or Acephalit^e, a term applied to seve¬ ral sects who refused to follow some noted leader. Thus, the persons who refused to follow either John of Antioch or St Cyril, in a dispute that happened in the council of Ephesus, were termed Acephali, without a head or leader. Such bishops, also, as were exempt from the jurisdiction and discipline of their patriarch, were styled Acephali. Acephali, the levellers in the reign of King Henry I. who acknowledged no head or. superior. They were reckoned so poor, that they had not a tenement by which they might acknowledge a superior lord. ACEPHALOUS, or Acephalus, in a general sense, without a head. The term is more particularly used in speaking of certain nations or people, represented by ancient naturalists and cosmographers, as well as by some modern travellers, as formed without heads; their eyes, mouth, &c. being placed in other parts. Such are the Blemmyes, a nation of Africa, near the head of the Niger, represented to be by Pliny and Solinus: Blemmyis traduntur capita abesse, ore et ocidis pectori affixis. Ctesias and Solinus mention others in India, near the Ganges, sine cervice, oculos in humeris habentes. Mela also speaks of people, quibus capita et vultus in pec- tore sunt. And Suidas, Stephanus Byzantinus, Vopiscus, and others after them, relate the like. Some modern tra¬ vellers have pretended to find acephalous people in Ame¬ rica. Several opinions have been framed as to the origin of the fable of the Acephali. The first is that of Thomas Bartholine, who turns the whole into a metaphor; being convinced, that the name Acephali was anciently given to such as had less brain, or conducted themselves less by the rules of prudence, than others. Olearius rather apprehends that the ancient voyagers, viewing pertain barbarous people from the coasts, had been imposed on by their uncouth dress; for that the Samogitians, being short of stature, and going in the severity of winter with their heads covered in hoods, seem at a distance as if they were headless. F. Lafitau says, that by Acepfiali 92 AGE Acephalusare only meant people whose heads are sunk below their || shoulders. Hulsius, in his epitome of Sir Walter Ra- Acerra. Sigh’s Voyage to Guiana, speaks of a people which that traveller found between the lakes of Panama and Cassipa, who had no head or neck; and Hondius, in his map, marks the place with the figures of these monsters. But y Descript. De Laet1 rejects the story; being informed by others, Amer. lib. that the inhabitants of the banks of the Caora, a river that xvii. c. 22. flows out 0f the lake of Cassipa, have their heads so far sunk between their shoulders, that many believed they had their eyes in their shoulders, and their mouths in their breasts. Acephalus, an obsolete term for the taenia or tape¬ worm, which was long supposed to be acephalous. I he first who gave it a head was Tulpius, and after him Fehr: the former even makes it biceps, or two-headed. Acephalus is also used to express a verse defective in the beginning. ACEQUAR A, a town of the kingdom of Naples, in the principality of Citra, with 2263 inhabitants. ACEQUARIA, a town of Italy, in the grand duchy of Modena, about 18 miles south-west from the capital, with 1360 inhabitants. It is chiefly celebrated for its mineral springs. ACEQUI, a city, the capital of the province of the same name, in Italy. It is a walled city, partly on the banks of the Bormida, and partly on a hill rising above that river. It has a cathedral, three monasteries, and a nunnery. The inhabitants, who chiefly trade in silk, are 6600. There are some celebrated warm baths, which were known in ancient times, and used by the Romans. It is in Long. 8. 31. E. Lat. 44. 40. N. ACER, the Maple or Sycamore Tree. ACERA, the name of a town of Spain, on the river Carion, in the jurisdiction of Saldana and province of Valencia; and also of another on the Ebro, in the depart¬ ment of Reynosa and province of Toro. ACERB, a sour rough astringency of taste, such as that of unripe fruit. ACERENZA, a town of the kingdom of Naples, in the province of Basilicata, 80 miles east from Naples, con¬ taining 1800 inhabitants. ACERINA, in Ichthyology, a name given by Pliny and other old naturalists to the fish we at this time call the ruffe. ACERNO, a town of Italy, in the citerior principality of Naples, with a bishop’s see, and 2400 inhabitants. It is situated 12 miles north-east of Saluno, in Long. 15. 46. E. Lat. 40. 45. N. ACERRA, in antiquity, an altar erected among the Romans, near the bed of a person deceased, on which his friends daily offered incense till his burial. The real intention probably was to overcome any offensive smell that might arise about the corpse. The Chinese have still a custom like this: they erect an altar to the de¬ ceased in a room hung with mourning, and place an image of the dead person on the altar, to which every one that approaches it bows four times, and offers oblations and perfumes. The acerra also signified a little pot, wherein were put the incense and perfumes to be burnt on the altars of the gods and before the dead. It appears to have been the same with what was otherwise called thuribulumandipyxis. The Jews had their acerrce, in our version rendered cen¬ sers ; and the Romanists still retain them under the name of incense pots. In Roman writers we frequently meet with plena acerra, a full acerra; to understand which, it is to be observed, that people were obliged to offer in¬ cense in proportion to their estate and condition; the ACE rich in larger quantities, the poor only a few grains: the Acerr, former poured out full acerrce on the altar, the latter took || out two or three bits with their fingers. ^sar Acerra, a town of Italy, in the kingdom of Naples, and in the Terra di Lavoro, seated on the river Agno, 7 miles north-east of Naples ; anciently Acerra. It con¬ tains 6256 inhabitants. Long. 14. 13. E. Lat. 40.55. N. ACESCENT, a word used to denote any thing which is turning sour, or which is slightly acid. It is only applied properly to the former of these two meanings. The second may be expressed by either of the two words acidulous or sub-acid. ACESINES, in Ancient Geography, a large and rapid river of India, which Alexander passed in his expedition into that country. The kingdorti of Porus, which was conquered by Alexander, lay between the Hydaspes and this river, which, uniting with the former and other con¬ siderable rivers, pours its waters into the Indus. Accord¬ ing to Major Rennell, the modern Chunab is the Acesines of the ancients. ACESIUS, a bishop of Constantinople in the reign of Constantine, was a rigid adherent to the Novatian doc¬ trines, according to which those whom persecutions had shaken from the faith, or who were guilty of any mortal sin after baptism, could not be admitted to the commu¬ nion of the church, even after exhibiting the most con¬ vincing proofs of sincere repentance. Constantine, who was extremely displeased with the severity of this rigid sect, in discouraging and rejeding repentance, is said to have thus expressed himself: “ Then, Acesius, make a ladder for yourself, and go up to heaven alone.” ACETABULUM, in antiquity, a measure used by the ancients, equal to one-eighth of our pint. It seems to have acquired its name from a vessel in which acetum or vinegar was brought to their tables, and which probably contained about this quantity. Acetabulum, in Anatomy, a cavity in any bone for re¬ ceiving the protuberant head of another, and thereby forming that species of articulation called Enarthrosis, Acetabulum, in Botany, the trivial name of a species of the peziza, or cup peziza, a genus belonging to the cryptogamia fungi of Linnaeus. It has got the name of acetabulum from the resemblance its leaves bear to a cup. ACETARY. Grew, in his Anatomy of Plants, applies this term to a pulpy substance in certain fruits, e. g. the pear, which is inclosed in a congeries of small calculous bodies towards the base of the fruit, and is always of an acid taste. ACETOSA, Sorrel ; by Linnaeus joined to the genus Rumex. ACETOSELLA, in Botany, a species of Oxalis. ACETOUS, an epithet applied to such substances as are sour, or partake of the nature of vinegar. ACETUM, Vinegar, the vegetable acid of the che¬ mists. ACH/EA, in Ancient Geography, a town of the island of Rhodes, in the district of lalysus, and the first and most ancient of all; said to be built by the Heliades, or grandsons of the sun. ACILEANS, the inhabitants of Achaia Propria, a Peloponnesian state. This republic was not considerable, in early times, for the number of its troops, nor for its wealth, nor for the extent of its territories; but it was famed for its probity, its justice, and its love of liberty, Its high reputation for these virtues was very ancient. The Crotonians and Sybarites, to re-establish order in their towns, adopted the laws and customs of the Achseans. Af¬ ter the famous battle of Leuctra, a difference arose betwixt the Lacedemonians and Thebans, who held the virtue of A C H A C H 93 A* cans this people in such veneration, that they terminated the dispute by their decision. The government of the Achaeans was democratical. They preserved their liberty till the time of Philip and Alexander; but in the reign of these princes, and afterwards, they were either subjected to the Macedonians, who had made themselves masters of Greece, or oppressed by domestic tyrants. The Achaean com¬ monwealth consisted of twelve inconsiderable towns in Peloponnesus. Towards the 124th Olympiad, about the time when Ptolemy Soter died, and when Pyrrhus invad¬ ed Italy, the republic of the Achaeans recovered its old institutions and unanimity. The inhabitants of Patrae and of Dymae were the first assertors of ancient liberty. The tyrants were banished, and the towns again made one commonwealth. A public council was then held, in which affairs of importance were discussed and determined. A register was appointed to record the transactions of the council. This assembly had two presidents, who were nominated alternately by the different towns. But instead of two presidents, they soon elected but one. Many neighbouring towns, which admired the constitution of this republic, founded on equality, liberty, the love of justice, and of the public good, were incorporated with the Achaeans, and admitted to the full enjoyment of their laws and privileges.—The arms which the Achaeans chief¬ ly used were slings. They were trained to the art from their infancy, by slinging from a great distance, at a cir¬ cular mark of a moderate circumference. By long prac¬ tice they took so nice an aim, that they were sure, not only to hit their enemies on the head, but on any part of the face they chose. Their slings were of a different kind from those of the Balearians, whom they far surpass¬ ed in dexterity. ACHiEI, Ach;eans, the inhabitants of Achaia Propria. In Livy, the people of Greece; for the most part called Achivi by the Roman poets. In Homer, the general name for Grecians. See Ach-zeans. ACHiEMENES, according to Herodotus, was grand¬ father of Cambyses, and great-grandfather of Cyrus the first, king of Persia. Most of the commentators of Ho¬ race are of opinion, that the Achaemenes whom that poet mentions, Ode xii. of his 2d book, was one of the Persian monarchs; but if that were true, he must have reigned before the Medes subdued the Persians; for we do not hear of any king of that name from the time that the Persians founded that great monarchy, which is looked upon as the second universal one. However this be, the epithet AcJuemenians is frequently given to the Persians in the old Latin poets. Acha:menes, son of Darius I. king of Persia, and brother of Xerxes, had the government of Egypt bestow¬ ed on him, after Xerxes had forced the Egyptians to re¬ turn to their allegiance. He some time after commanded the Egyptian fleet in the celebrated expedition which proved so fatal to all Greece. The Egyptians having again taken up arms after the death of Xerxes, Achasmenes was sent into Egypt to suppress the rebellion, but was vanquished by Inarus, chief of the rebels, succoured by the Athenians. ACHyEUS, cousin-german to Seleucus Ceraunus and Antiochus the Great, kings of Syria, became a very powerful monarch, and enjoyed the dominions he had usurped for many years; but at last he was punished for his usurpations in a dreadful manner, in the 140th year of Xj ili. Rome, as related by Polybius.1 , ACHAFALAYA, a river in Louisiana, in North Ame¬ rica, or more properly a secondary channel of the Missis- sippi, by which a part of its waters flows off from the main trunk, and passes to the Gulf of Mexico. Its mouth is about 100 miles westward of the proper mouth of the Achaia Mississippi.! 1| ACHAIA, a name taken for that part of Greece which Acheen. Ptolemy calls Hellas, the younger Pliny Gracia; now called Livadia. Achaia Propria, anciently a small district in the north of Peloponnesus, running westward along the bay of Co*- rinth, and bounded on the west by the Ionian Sea, on the south by Elis and Arcadia, and on the east by Sicyonia : inhabitants, the Achceans, properly so called; its metropolis Patra. It is now called Romania Alta, in the Morea. Achaia also denoted all those countries that joined in the Achaean league, reduced by the Romans to a province. Likewise for Peloponnesus. Achaiji: Presbyteri, or the Presbyters of Achaia, were those who were present at the martyrdom of St Andrew the apostle, a. d. 59; and are said to have written an epistle in relation to it. Bellarmin, and several other eminent writers in the church of Rome, allow it to be genuine; while Du Pin and some others expressly rer ject it. ACHAIUS, son of Ethwin, was raised to the crown of Scotland, a. d. 788. The Emperor Charlemagne sent an embassy to this prince, to request an alliance with him against the English, whose pirates so infested the seas that the merchants could not carry on their trade. The alliance was concluded in France, upon conditions so ad¬ vantageous to the Scots, that Achaius, to perpetuate the memory of it, added to the arms of Scotland a double field sowed with lilies. He died in 819. ACHALALACTLI, a species of king’s-fisher. ACHAN, the son of Carmi, of the tribe of Judah, at the taking of Jericho, concealed two hundred shekels of silver, a Babylonish garment, and a wedge of gold, con¬ trary to the express command of God. This sin proved fatal to the Israelites, who were repulsed at the siege of Ai. In this dreadful exigence, Joshua prostrated himself before the Lord, and begged that he would have mercy upon his people. Achan was discovered by casting lots, and he and his children were stoned to death. This ex¬ piation being made, Ai was taken by stratagem. (Josh, vii. viii.) ACHANE, an ancient Persian corn measure, contain¬ ing 45 Attic medimni. ACHARACA, anciently a town of Lydia, situated be¬ tween Tralles and Nysa; in which were the temple of Pluto and the cave Charonium, where patients slept in order to obtain a cure. ACHAT, in Law, implies a purchase or bargain. And hence probably purveyors were called Achators, from their making bargains. ACHATES, the companion of iEneas, and his most faithful friend, celebrated in Virgil. Achates, in Natural History, the same as Agate. Achates, in Ancient Geography, a river of Sicily, now the Drillo ; which runs from north to south, almost pa¬ rallel with, and at no great distance from the Gela ; and rises in the north of the territory of Noto. It gave name to the achates, or agate, said to be first found there. ACHAZIB, or Achzib, in Ancient Geography, a town of Galilee, in the tribe of Asher, nine miles from Ptole- mais.—Also a town in the more southern parts of the tribe of Judah. ACHEEN, Ache', or Achen, a kingdom of Sumatra, in the East Indies, situated on the north-western part of the island, and not extending inland above 50 miles to the south-east. It was formerly a flourishing and extensive state, but has now greatly declined from its importance, having become a prey to anarchy, from the contests of 94 A C H A C H Acheen. petty chiefs. In 1820 it was bounded, according to the most correct reports, by Tamiang on the eastern, and Sinkel on the western coast of Sumatra. Acheen is es¬ teemed comparatively healthy, being more free from woods and swamps than most other portions of the island; and the fevers and dysenteries to which these are supposed to give occasion, are there said to be un¬ common. The soil is light and fertile, and produces a variety of the finest fruits and vegetables; also rice and cotton in great plenty and perfection. Cattle are abundant, and reasonable in price. Though no longer the great mart of eastern commodities, it still carries on a consider¬ able trade with the natives of that part of the coast of Indostan called Tellinga, who supply it with the cotton goods of their country, and receive in return, gold dust, sapan wood, betel-nut, patch-leaf, a little pepper, sulphur, camphor, and benzoin. The country is supplied with Bengal opium, and also with iron, and many other articles of merchandise, by the European traders. A manufac¬ ture to some extent of a thick species of cotton cloth, and of striped and checked stuffs for the short drawers Worn both by Malays and Achenese, is established here, and meets with an extensive sale. They weave also very handsome silk pieces, of a particular form, for that part of the dress which is called by the Malays cayen serrong. But this manufacture has of late declined, owing probably to the decay of industry among the in¬ habitants, and also to the failure in the breed of silk-worms. Gold dust is collected in the mountains near Acheen, but the greater part is brought from the southern ports of Nalaboo and Soosoo. Sulphur is gathered from a vol¬ canic mountain in the neighbourhood, which supplies their own consumption for the manufacture of gunpowder, and admits of a large exportation. Having no convenient coins, though most species of money will be taken here at a valuation, traders commonly make their payments in gold dust, and for that purpose are all provided with scales or small steelyards. They carry their gold about them, wrapped up in pieces of bladder, and often pur¬ chase to so small an amount as to make use of grain or seeds for weights. They have besides a thin adulterated gold coin, rudely stamped with Arabic characters, called mans. In their persons the Achenese differ from the rest of the Sumatrans, being taller, stouter, and of a darker com¬ plexion. They do not appear to be a distinct people, but are thought, with great appearance of reason, to be a mixture of Battas, Malays, and Moors, from the west of India. In their dispositions they are more active and industrious than their neighbours; they possess more penetration and sagacity; hav$ more general knowledge; and, as merchants, they deal upon a more extensive and liberal footing. Their religion is Mahometanism ; and having a great number of mosquqs and priests, its forms and cere¬ monies are strictly observed. They speak a mixed lan¬ guage of Malay and-Batta, with all the other jargons used by the eastern Mahomedans. In writing, they use the Malay character. The monarchy is hereditary, and the king usually main¬ tains a guard gf 100- sepoys about his palace. When Acheen was a flourishing state, he ruled with despotic authority. There was, however, according to Mr Marsden, a grand council of the nation, which consisted of the sultan at its head; of four chief counsellors, and eight of a lower degree, who sat qn the king’s right hand; and of 16 others who sat on his left. How far this council shares or con¬ trols the royal prerogative, does not seem to be ascertained. At the king’s feet,” says Mr Marsden, “ sits a woman, to whom he makes known his pleasure; by her it is com¬ municated to an eunuch, who sits next to her; and by Acl him to an officer, who then proclaims it aloud to the as-k^ sembly. There are also present two other officers, one of whom has the government of the bazar or market, and the other the superintending and carrying into execution the punishment of criminals. All matters relative to commerce and the customs of the port come under the jurisdiction of another functionary, who performs the ce¬ remony of giving the chap or 'licence for trade ; which is done by lifting a golden-hafted kris over the head of the merchant who arrives, and without which he dares not to land his goods. Presents, the value of which is become pretty regularly ascertained, are then sent to the king and his officers. If the stranger be in the style of an ambassador, the royal elephants are sent down to carry him and his letters to the monarch’s presence; these being first delivered into the hands of an eunuch, who places them in a silver dish, covered with rich silk, on the back of the largest elephant, which is provided with a machine for that purpose. Within about an hundred yards of an open hall where the king sits, the cavalcade stops, and the ambassador dismounts, and makes his obeisance by bending his body and lifting his joined hands to his head. When he enters the palace, if an European, he is obliged to take off his shoes; and having made a second obeisance, is seated upon a carpet on the floor, where betel is brought to him.” The crown revenues, which fluctuate considerably, are derived from import and ex¬ port duties levied on all goods. Monopolies, the approved resource of despotism, also afford a revenue. These are managed by the officer who has the superintendence of commerce, and who frequently uses his power as an in¬ strument of extortion. Acheen, like all states in the same stage of civilisation, is distinguished by the severity of its punishments ; and no commutation is admitted, as in the southern countries. But it is on the poor chiefly that the rod of justice falls with its full weight, the nobles being secure from its retri¬ bution by the number of their dependents. Petty theft is punished by suspending the criminal from a tree, with a guh or heavy weight tied to his feet; or by cutting off a finger, a hand, or leg, according to the nature of the theft. Many of these mutilated and wretched objects are daily to be seen in the streets. Robbery on the high¬ way and housebreaking are punished by drowning, and afterwards exposing the body on a stake for a few days. If the robbery is committed upon an imaum or priest, the sacrilege is expiated by burning the criminal alive. A man who is convicted of adultery is delivered up to the friends and relations of the injured husband. These dis¬ couragements to vice might seem to bespeak a moral and virtuous people; yet all travellers agree in representing the Achenese as one of the most dishonest and flagitious nations of the East. * Acheen was first visited by Portuguese adventurers in 1509, after they had discovered the passage to the East Indies by the Cape of Good Hope. Hostilities imme¬ diately commenced with the inhabitants, and continued with various success, until the Portuguese lost Malacca in 1641. About the year 1586 the monarchy of Acheen attained to its greatest height of power and prosperity. It had a flourishing commerce ; and the port of Acheen was crowded with vessels from all the Asiatic countries, which were allowed to carry on their trade with the most perfect security. About the year 1600, when the Dutch navigators had penetrated to these seas, some of their vessels which had entered the port of Acheen were nearly cut off by the treachery of the inhabitants. It was in 1602 that Acheen was first visited by the English ship*. a e h cheen. under Captain Lancaster, where they were well recelv- > ecl. In 1607, the reigning sultan, having greatly extended his dominions on every side, assumed the title of sovereign. He had some correspondence with King James; and in answering one of his letters, he takes the title of King of Sumatra, and intimates to the king of England his wish that he would send out to him one of- his countrywomen for a wife. The French visited Acheen in 1621 under Commo¬ dore Beaulieu. The Dutch were now become the powerful rivals of the Portuguese in the eastern seas. They suc¬ ceeded in 1640, by the aid of their allies the Achenese, in wresting from them Malacca, which they had so long maintained. They afterwards commenced their encroach¬ ments on the Achenese, and reduced the extent of their ancient dominion, which, joined to the weakness of the government, occasioned the decline of the Achenese power. In 1641, the sultan Peducka Siri, who, though of a cruel disposition, was a powerful sovereign, died; and the Achenese monarchy continued in the female line till 1700, when a priest found means to acquire the supreme power. The country was agitated during the whole of the eighteenth century by anarchy, and the most san¬ guinary revolutions. In 1813, the state of Acheen, for¬ merly so flourishing, was found with hardly any form of civil order existing, every port and village being occupied by petty usurpers, who subsisted by piracy and smug¬ gling. At length the reigning monarch was compelled to abdicate the throne in favour of a shop-keeper’s son in Prince of Wales Island; but he was restored in 1819 to his dignity. In the following year, Mr Sartorius, being deputed to Acheen, found the country in a most miserable state; the king’s authority a mere nullity; and though a commercial treaty had been concluded, there appeared in the distracted state of the country not the least chance of its provisions being carried into effect, without some direct and active interference to uphold the authority of the government. Acheen, the capital of the above state, is situated on a river at the north-western extremity of Sumatra, and about a league from the sea, where a road is formed, in which the shipping may be secure under the shelter of several islands. The town is indifferently built of bam¬ boos and rough timber, and raised some feet from the ground on account of the overflow of the river in the rainy season. Its appearance and the nature of the buildings resemble the generality of the Malay bazars, excepting that the superior wealth of this place has occa¬ sioned a great number of public edifices, which do not however possess the smallest? pretensions to magnificence. The sultan’s palace, which is the chief public building, a very rude and uncouth piece of architecture, designed to resist the force of an enemy, and surrounded with a moat and strong walls, but without any regular plan, or any view to the modern system of military attack. Several pieces of ordnance are planted near the gate, some of which are Portuguese; but two were sent from England by James L, on which the founder’s name and the date are still legible. The river on which the town is situated is not large ; and the stream being di¬ vided into several channels, is rendered shallow at the bar. In the dry monsoon it will not admit boats of any burden, much less large vessels, which lie without in the road formed by the islands off the point. The com¬ merce has fallen off. The chief exports are, brimstone, betel-nut, ratans, benzoin, camphor, gold dust, pepper, and horses ;'the imports, opium, salt, piece-goods, muslin, &c. The town fcofitains-about 8000 houses.

Marsden’s Sumatra, Forrest’s Voyage, Hamilton’s Ehst India Gazetteer* A c n sis ACHELOUS, in fabulous history, wrestled with Her- Achelous cules, for no less a prize than Dejanira, daughter of King 11 CEneus ; but as Achelous had the power of assuming all Acfieri- shapes, the contest was long dubious. At last, as he took that of a bull, Hercules tore off one of his horns, so that he was forced to submit, and to redeem it by giving the conqueror the horn of Amalthea, the same with the cor¬ nucopia, or horn of plenty; which Hercules, having filled with a variety of fruits, consecrated to Jupiter. Some explain this fable, by saying, that Achelous is a winding river of Greece, whose stream was so rapid, that it roared like a bull, and overflowed its banks; but Hercules, by bringing it into two channels, broke off one of the horns, and so restored plenty to the country. See the next article. Achelous, a river of Acarnania, which rises in Mount Pindus, and dividing iEtolia from Acarnania, falls into the Ionian Sea. It was formerly called Thoas, from its impe¬ tuosity, and king of rivers. (Homer.) The epithet Ache- loius is used for Aqueus (Virgil), the ancients calling all water Achelous, especially in oaths, vows, and sacrifices, according to Ephorus : now called Aspro Potamo. Rivers are by the ancient poets called Tauriformes, either from the bellowing of their waters, or from their ploughing the earth in their course. Hercules, restraining by dykes and mounds the inundations of the Achelous, is said to have broken off one of his horns, and to have brought back plenty to the country. See the preceding article. ACHENWALL, Gottfried, a German writer, who obtained considerable celebrity from having first reduc¬ ed statistics to a regular branch of study, and excited much of the attention of others to the subject. He was born at Elbing, in East Prussia, in October 1719. He studied, according to the custom of Germany, in several universities; and was at Jena, Halle, and Leipsic, before he took a degree at the last of those cities. He removed to Marburg in 1746, where he continued during two years to read lectures on history, and on the law of nature and of nations, and commenced those inquiries in statistics by which his name became known. In 1748 he removed to Gottingen, where he resided till his death in 1772. He made several journeys to Switzerland, France, Holland, and England, and published numerous small but accurate works on their history, population, products, laws, reve¬ nues, and administration. His chief merit lay in the lec¬ tures he delivered at the university, where he was a pro¬ fessor, in which he brought forward, in a fixed and steady form, and in a new and luminous point of view, those active powers of states which conduce to their physical and moral prosperity. He was married in 1752 to a lady named Walther, who obtained some celebrity by a volume of poems published in 1750. Both Achenwall and his, wife were great contributors to the periodical publications of Gottingen, by which they gained a degree of reputa¬ tion which, from their labours not having been published in a separate form, has been since nearly forgotten, and owing to which we are unable to place before our readers a correct list of their writings. ’ > • (g.)

During the period of his reign, the Turkish empire enjoyed at one time great pros¬ perity, and at another was depressed with adversity. The Asiatic rebels, who took refuge in Persia, involved the two empires in a war, during which the Turks lost Bag¬ dad, to recover which every effort proved unsuccessful. In his reign, Transylvania and Hungary were the scenes of war between the Turks and Germans. In addition to the calamities and distresses of war abroad, and internal tumults and broils, a pretender to his throne disturbed his repose, and made attempts on his life. He was much devoted to amusements, and spent his time chiefly in the harem and in the sports of the field. His seraglio con¬ sisted of 3000 women; and his hunting establishment was composed of 40,000 falconers, and an equal number of huntsmen, in different parts of his dominions. He ex¬ pended great sums of money in building, and particularly on a magnificent mosque which he erected in the Hippo¬ drome. Achmet was less cruel than some of his prede¬ cessors, but he was haughty and ambitious. He died in 1617, at the age of 29. His three sons successively ascended the throne after him. Achmet II. emperor of the Turks, son of Sultan Ibra¬ him, succeeded his brother Solyman in 1691. The ad¬ ministration of affairs during his reign was feeble and un¬ settled. The Ottoman territory was overrun by the im¬ perialists; the Venetians seized the Morea, took the isle of Chios, and several places in Dalmatia; and the Arabs attacked and plundered a caravan of pilgrims, and even laid siege to Mecca. Though he never discovered the vigour and sagacity that are essentially requisite in the character of a sovereign, in private life he wras mild, de¬ vout, and inoffensive. He was fond of poetry and music ; and to those about his person, he was cheerful and ami¬ able. He died in 1695, at the age of 50. Achmet III. emperor of the Turks, son of Mahomet IV. succeeded his brother Mustapha II. who was deposed in 1703. After he had settled the discontents of the em¬ pire, his great object was to amass wealth. With this view he debased the coin, and imposed new taxes. He received Charles XII. of Sweden, who took refuge in his dominions after the battle of Pultowa in 1709, with great hospitality; and, influenced by the sultana mother, he de¬ clared war against the Czar Peter, Charles’s formidable rival. Achmet recovered the Morea from the Venetians; but his expedition into Hungary was less fortunate, for his army was defeated by Prince Eugene at the battle of Peterwaradin, in 1716. As the public measures of Ach¬ met were influenced by ministers and favourites, the em¬ pire during his reign was frequently distracted by politi¬ cal struggles and revolutions. The discontent and sedi¬ tion of his soldiers at last drove him from the throne. He was deposed in 1730, and succeeded by his nephew Mahomet V. He wras confined in the same apartment which had been occupied by his successor previously to his elevation to the throne, and died of apoplexy in 1736, at the age of 74. The intentions of this prince, it is said, were upright; but his talents were moderate, never dis¬ covering that vigour of mind and steadiness of action which are so necessary in the character of a sovereign. Excessive confidence in his vizier diminished the splen¬ dour of his reign, and probably tended to shorten the period of it.

The invention of the Invention telescope, by which the powers of vision are extended °f t*16 lele- to the utmost boundaries of space, forms an epoch inSC0Pe* the history of science. The human intellect had at last emerged from the long night of error, and begun to shine with unclouded lustre. The age of erudition, which arose on the revival of letters, had been succeeded by the age of science and philosophy. The study of the ancient classics had infused some portion of taste and vigour. But men did not long remain passive admirers; they began to feel their native strength, and hastened to exert it. A new impulsion was given to the whole frame of society; the bolder spirits, bursting from the trammels of authority, ventured to question inveterate opinions, and to explore, with a fearless yet discerning eye, the wide fields of human knowledge. Copernicus had partly restored the true system of the world; Stevinus had ex¬ tended the principles of mechanics; the fine genius of Galileo had detected and applied the laws of motion ; the bold excursive imagination of Kepler had, by the aid of immense labour, nearly completed his discovery of the great laws which control the revolutions of the heavenly bodies; and our countryman Napier had just rendered himself immortal by the sublime discovery of logarithms. At this eventful period, amidst the fermentation of talents, the refracting telescope was produced by an obscure glass- grinder in Holland,—a country then fresh from the struggle against foreign oppression, and become the busy seat of commerce and of the useful arts. Yet the very name of that meritorious person, and the details connected with his invention, are involved in much obscurity. On a question of such peculiar interest we shall afterwards en¬ deavour to throw some light, by comparing together such incidental notices as have been transmitted by contempo¬ rary writers. In the mean time, we may rest assured that the construction of the telescope was not, as certain authors would insinuate, the mere offspring of chance, but was, like other scientific discoveries, the fruit of close and patient observation of facts, directed with skill, and incited by an ardent curiosity. A new and perhaps incidental N 98 ACHROMATIC GLASSES. Achroma- appearance, which would pass unheeded by the ordinary ^ spectator, arrests the glance of genius, and sets all the powers ot fancy to work. But the inventor of the tele¬ scope, we are informed, was acquainted besides with the elements of geometry, which enabled him to prosecute his views, and to combine the results with unerring success. No sooner was this fine discovery—admirable for the very simplicity of its principle—whispered abroad, than it fixed the attention of the chief mathematicians over Europe. Kepler, with his usual fertility of mind, produced a trea¬ tise on Dioptrics, in which he investigated at large the distinct effects of the combinations of different lenses.1 Galileo, from some very obscure hints, not only divined the composition of the telescope, but actually constructed one, with a concave eye-glass, which still bears his name. This telescope is shorter, but gives less light than another one proposed by Kepler, and called the astronomical tele¬ scope, which inverts the objects, and consists likewise of only two lenses, that next the eye being convex. With such an imperfect instrument—the same, indeed, though of rather higher magnifying power, with our mo¬ dern opera-glass—did the Tuscan artist, as our great poet quaintly styles the philosopher, venture to explore the heavens.2 He noticed the solar spots, surveyed the cavernous and rocky surface of the moon, observed the successive phases of the planet Venus, and discovered the more conspicuous of Jupiter’s satellites. The truths thus revealed shook the inveterate prejudices of the learn¬ ed, and furnished the most triumphant evidence to the true theory of the universe. It is painful to remark, that the application of the first telescope in the country which had given it birth was directed to a very different purpose. The maker, after having finished one, judging it of singular use in the mili¬ tary profession, was naturally induced, by the hope of patronage, to present it to the younger Prince Maurice, whose bravery and conduct had so beneficially contribut¬ ed to the independence of the United Provinces. But at this moment a bloody tragedy was acting in Holland. The chief of the republic, not content with that high station which the gratitude of his fellow-citizens had con¬ ferred upon him, sought to aggrandize his power by crush¬ ing all opposition. In the prosecution of his ambitious designs, he artfully gained the favour of the undiscerning populace, and joining his intrigues fio the violence of the Calvinistic clergy, he succeeded in preferring the charge of a plot against the more strenuous supporters of the com¬ monwealth, which involved them in ruin. Not only was the celebrated Grotius condemned to the gloom of perpetual imprisonment, but the aged senator Barneveldt, whose wise and upright counsels had guided the state amidst all the troubles of a long revolutionary conflict, was led to the scaffold, on the 14th of May 1619, while his persecutor, Achr., ashamed to approach the spectacle of his sufferings, beheld ti at a distance, with the coolness of a tyrant, from the win- ^*as . dows of his palace, and by help of a telescope, the gesture'^’'7 •' and aspect of the venerable patriot, and all the melancholy circumstances attending the decollation.3 * * * The skill and ingenuity of artists and mathematicians Imprc , were now exerted in attempts to improve the construction of the t, of an instrument so fortunately contrived. The perfec-SC0Pe' j tion of the telescope would require the union, as far as they are capableof being conjoined, of three different qualities,— distinctness of vision, depth of magnifying power, and ex¬ tent of field. Of these requisites, the first two are evidently the most important, and to attain them was an object of persevering research. For the condition of amplitude and clearness, it was necessary that the principal image, or the one formed by the eye-glass, should be large, bright, and well defined. On the supposition then genei'ally re¬ ceived, that, in the passage of light through the same media, the angle of incidence bears a constant, ratio to the angle of refraction, which is very nearly true in the case of small angles, it followed, as a geometrical consequence, that the spherical figure would accurately collect all the rays into a focus. To obtain the desired improvement of the telescope, therefore, nothing seemed to be wanting but to enlarge sufficiently its aperture, or to employ for the eye-glass a more considerable segment of the sphere. On trial, however, the results appeared to be at variance with the hasty deductions of theory, and every sensible en¬ largement of aperture was found to occasion a correspond¬ ing glare and indistinctness of vision. But a discovery made soon afterwards in optics led to more accurate con¬ clusions. Willebrord Snell, a very ingenious Dutch ma- Snell, thematician, who was snatched away at an early age, traced out by experiment, about the year 1629, the true law that connects the angles of incidence and of refraction; which the famous Descartes, who had about this time chosen Holland for his place of residence, published, in 1637, in his Dioptrics, under its simplest form, establish¬ ing, that the sines of those angles, and not the angles themselves, bore a constant ratio in the transit of light between the same diaphanous media. It hence followed, that the lateral rays of the light which enter a denser medium, bounded by a spherical surface, in the direction of the axis, will not meet this axis precisely in the same point, but will cross it somewhat nearer the surface. In short, the constant ratio or index of refraction will be that of the distances of the actual focus from the centre of the sphere, and from the point of external impact. Since an arc differs from its sine by a quantity nearly proportioned to its cube, the deviation of the extreme rays from the correct focus, or what is called the spherical aberration, 1 Kepler explained the construction of the astronomical telescope with two convex lenses; he likewise proposed a third glass to restore the inverted image. But Schemer first employed the astronomical telescope, and described his observations with it in 1630. Father Kheita placed the third lens of Kepler near the primary focus, and thus enlarged the field of view. Such is the arrangement in the common spy-glass, which he gave in 1665. 2 „ like the moon, whose orb Through optic glass the Tuscan artist views At evening from the top of Fesole', Or in Yaldarno, to descry new lands, Rivers, or mountains, on her spotty globe. {Paradise Lost, hook i. 286-290 ) * The discovery of the telescope, from the mystery at first practised, is involved in considerablAincertainty. The most probable statement, however, ascribes the invention so early as 1590 to Zachary Jansen, an intelligent spectacle-maker at Middleburg. This intelligent person, led by accident to exercise his ingenuity on the subject, appears to have in private matured the execution of that wonderful though simple instrument. In a short time, however, the secret had transpired; and Laprey or Lippersheim, a townsman of the same profession, produced telescopes for sale between the years 1600 and 1610. But, in 1608, Jansen likewise constructed the compound microscope; and both instruments, by the activity of trade, were now spread quickly over Europe. The telescope was copied, and perhaps improved, by Adrian Metms, son of the celebrated mathematician. It was publicly sold at Frankfort in 1608, and m the following year the instruments were brought by Drebbel for sale to London.

It was now attempted to modify ^ the figure of the object-glass, and to give it those curved surfaces which an intricate geometrical investigation marks out as fitted to procure a perfect concentration of all the refracted rays. Various contrivances were accordingly proposed for assisting the artist in working the lenses into a parabolic or spheroidal shape, and thus obtaining the exact surfaces generated by the revolution of the different conic sections. All those expedients and directions, how¬ ever, were found utterly to fail in practice, and nature seemed, in this instance, to oppose insurmountable barriers to human curiosity and research. Philosophers began to despair of effecting any capital improvement in dioptrical instruments, and turned their views to the construction of those depending on the principles of catoptrics, or formed by certain combinations qf reflecting specula. In 1663, (.'gory, the famous James Gregory, who in many respects may be regarded as the precursor, and in some things even the rival of Newton, published his Optica Promota ; a work distinguished by its originality, and containing much in¬ genious research and fine speculation. In this treatise, a complete description is given of the reflecting telescope now almost universally adopted, consisting of a large per¬ forated concave reflector combined with another very small and deep speculum placed before the principal focus. But such was still the low state of the mechanical arts in England, that no person was found capable of casting and polishing the metallic specula with any tolerable delicacy, and the great inventor never enjoyed the satisfaction and transport of witnessing the magic of his admirable contriv¬ ance. It was after the lapse of more than half a century, Nlley- that Hadley—to whom we likewise owe another instrument scarcely less valuable, the quadrant, or sextant, known by his name—at last succeeded in executing the reflecting telescope. In the first attempt, silvered mirrors had been substituted for the specula; nor did the reflectors come to obtain much estimation, till, about the year 1733, the ingenious Mr Short distinguished himself by constructing them in a style of very superior excellence. But though thus late in guiding the efforts of artists, the optical treatise of Gregory proved the harbinger of that bright day which soon arose to illumine the recesses M ton. of physical science. The capacious mind of Newton, nursed in the calm of retirement and seclusion, was then teem¬ ing with philosophical projects. In 1665, when the tre¬ mendous visitation of the plague raged in London, and threatened Cambridge and other places communicating with the capital, this sublime genius withdrew from the routine of the university to his rural farm near Grantham, and devoted himself to most profound meditation. Amidst i his speculations in abstruse mathematics and theoretical astronomy, Newton was induced to examine the opinions entertained by the learned on the subject of light and co¬ lours. With this view he had recently procured from the Continent some prisms of glass, to exhibit the phenomena of refraction. Having placed the axis of the prism or glass wedge at right angles to a pencil of light from the sun, admitted through a small hole of the window-shutter m a darkened room, he contemplated the glowing image or spectrum now formed on the opposite wall or screen. This illuminated space was not round, however, as the young philosopher had been taught to expect, but appear¬ ed very much elongated, stretching out five times more than its breadth, and marked by a series of pure and bril¬ liant colours. It was therefore obvious that the colours were not confined to the margin of the spectrum, nor could proceed from any varied intermixture of light and shade ; and the conclusion seemed hence irresistible, that Achroma- the white pencil, or solar beam, is really a collection of tic distinct rays, essentially coloured and differently refract- Glasses, ed; that the ray, for instance, which gives us the sensa-V^v^^ tion of the violet, is always more bent aside from its course by refraction than the ray which we term green,—and that this green ray again is more refracted than the red. When the spectrum was divided, by interposing partially a small screen, and each separate parcel of rays made to pass through a second prism, they, still retained their peculiar colour and refractive property, but now emerged in parallel, and not in diverging lines as at first. The sun’s light is thus decomposed by the action of the prism into a set of primary coloured rays; and these rays, if they be after¬ wards recombined in the same proportions, will always form a white pencil. It was hence easy to discern the real cause of the imperfection of dioptrical instruments, which is comparatively little influenced by the figure of the object-glass or spherical aberration, but proceeds mainly from the unequal refraction of light itself. The focal distance of the red ray being, in the most favourable case, about one fortieth part shorter than that of the violet ray, the principal image is necessarily affected with mistiness, and its margin always encircled by a coloured ring; for each point of the remote object from which the light arrives is not represented by a corresponding point in the image, but by a small circle composed of graduat¬ ing colours, the centre being violet and the circumference red. This radical defect seemed at that time to be alto¬ gether irremediable. Newton had recourse, therefore, to the aid of catoptrics, and contrived his very simple though rather incommodious reflecting telescope, consisting of a concave speculum, with a small plane one placed oblique¬ ly before it, to throw the image towards the side of the tube. This instrument he actually constructed; and with all its rudeness, it promised essential advantages to astronomy. The Newtonian reflector, after having been long neglected, was lately revived by Dr Herschel; and from its great simplicity and moderate dissipation of light, it is perhaps on the whole not ill calculated for celestial observations. These unexpected and very important discoveries, wfliich entirely changed the face of optics, were soon com¬ municated to the Royal Society, and published in the Philosophical Transactions for 1672. They were not re¬ ceived however by the learned with that admiration to which they were justly entitled, but gave occasion to so much ignorant opposition and obstinate controversy, that the illustrious author, thoroughly disgusted at such un¬ merited reception, henceforth, pursuing his experimental researches in silence, made no disclosure of them to the world till more than thirty .years afterwards, when his fame being mature, and his authority commanding respect, he suffered his Treatise on Optics to appear abroad. This celebrated production has long been regarded as a model of pure inductive science. The experiments which it re¬ lates appear ingeniously devised; the conclusions from them are drawn with acuteness, and pursued with exqui¬ site skill; and the whole discourse proceeds in a style of measured and elegant simplicity. Though the researches were conducted by a process of strict analysis, the com¬ position of the work itself is cast into the synthetical or didactic form, after the manner followed in the elemen¬ tary treatises of the ancient mathematicians. But with all its beauty and undisputed excellence, it must be con¬ fessed that the treatise of optics is not exempt from faults, and even material errors. We should betray the interests of science, if we ever yielded implicit confidence even to the highest master. It is the glory of Newton to have led the way in sublime discovery, and to have impressed 100 ACHROMATIC GLASSES. Glasses. Achroma- whatever he touched with the stamp of profound and ori- tic ginal genius. The philosopher paid the debt of human , infirmity, by imbibing some tincture of the mystical spirit of the age, and taking a slight bias from the character of his studies. The difficult art of experimenting was still in its infancy, and inquirers had not attained that delicacy and circumspection which, in practice, are indispensable for obtaining accurate results. Most of the speculations in the second and third books of Newton’s Optics, as we shall afterwards have occasion to observe, are built on mistaken or imperfect views of some facts, which the ad¬ mixture of extraneous circumstances had accidentally disguised. The very ingenious, but hasty, and often un¬ tenable hypotheses, which are subjoined, under the mo¬ dest and seemingly hesitating title of Queries, have, on the whole, been productive of real harm to the cause of science, by the splendid example thus held forth to tempt the rashness of loose experimenters, and of superficial reasoners. Even in the first book of Optics, some of the capital propositions are affected by hasty and imperfect statements. The term ref Tangibility, applied to the rays of light, is at least unguarded; it conveys an indistinct conception, and leads to inaccurate conclusions. The dif¬ ferent refractions which the primary rays undergo are not absolute properties inherent in these rays themselves, but depend on the mutual relation subsisting between them and the particular diaphanous medium. When the me¬ dium is changed, the refraction of one set of rays cannot be safely inferred from that of another. Nay, in the pas¬ sage among certain media, those rays which are designat¬ ed as the most refrangible will sometimes be the least re¬ fracted. To ascertain correctly, therefore, the index of re¬ fraction, it becomes necessary, in each distinct case, to examine the bearing or disposition of the particular species of rays ; since the principle, that the refraction of the ex¬ treme rays is always proportioned to that of the mean rays, involves a very false conclusion. When Newton attempted to reckon up the rays of light decomposed by the prism, and ventured to assign the famous number seven, he was apparently influenced by some lurking disposition towards mysticism. If any un¬ prejudiced person will fairly repeat the experiment, he must soon be convinced, that the various coloured spaces which paint the spectrum slide into each other by indefi¬ nite shadings; he may name four or five principal colours, but the subordinate divisions are evidently so multiplied as to be incapable of enumeration. The same illustrious mathematician, we can hardly doubt,' was betrayed by a passion for analogy, when he imagined, that the primary colours are distributed over the spectrum after the pro¬ portions of the diatonic scale of music, since those inter¬ mediate spaces have really no precise and defined limits. Had prisms of a different kind of glass been used, the dis¬ tribution of the coloured spaces would have been mate¬ rially changed. The fact is, that all New'ton’s prisms being manufactured abroad, consisted of plate or crown glass, formed by the combination of soda, or the mineral alkali, with silicious sand. The refined art of glass-mak¬ ing had only been lately introduced into England, and that beautiful variety called crystal, or flint-glass, which has so long distinguished this country, being produced by the union of a silicious material with the oxyde of lead, was then scarcely known. The original experimenter had not the advantage, therefore, of witnessing the varied ef¬ fects occasioned by different prisms, which demonstrate, that the power of refraction is not less a property of the peculiar medium than of the species of light itself. He mentions, indeed, prisms formed with water confined by plates of glass; but the few trials which he made with them had evidently been performed with no sufficient Achi:!. attention. In spite of his habitual circumspection, he t could not always restrain the propensity so natural to ^a: genius, that of hastening to the result, and of trusting to^'"^ general principles more than to any particular details. But the same indulgent apology will not be conceded to some later authors. It is truly astonishing that systematic wi'iters on optics, in obvious contradiction to the most un¬ doubted discoveries related by themselves, should yet re¬ peat with complacency the fanciful idea of the harmonical composition of light. Admitting the general conclusion which NewTon con¬ ceived himself entitled to draw from analogy and concur¬ ring experiment, that “ the sine of incidence of every ray considered apart, is to the sine of refraction in a given ratioit was strictly demonstrable, that no contrary refrac¬ tions whatever, unless they absolutely restored the pencil to its first direction, could collect again the extreme rays, and produce, by their union, a white light. Thus, let the ratios of the sines of the angles of incidence and refraction of the violet rays in their transit from air to other two denser mediums, be expressed by 1 : ilf and \ : m; and the like ratios of the red rays under the same circumstances, by 1 : iV and 1 : w; where M m and N n respectively denote the refracting indices of those ex¬ treme rays. It is manifest that the refracting indices, corresponding to the passage of the violet and red rays from the first to the second medium, will be represented by M-N, and m-n. But by hypothesis, M: m \ : N: n, and consequently M: m : : M-N: ni-n\ so that the ex¬ treme rays would not be still separated and dispersed in proportion to the mean extent of the final refraction. The great philosopher appears to have contemplated with re¬ gret the result of his optical principle; and he had the penetration to remark, that if a different law had ob¬ tained, the proper combination of distinct refracting media would have corrected the spherical aberration. With this view, he would propose for the object- glass of a telescope, a compound lens, consisting of two exterior meniscuses of glass, their out- J|p^|p sides being equally convex, and their insides of jpl ^=^ip similar but greater concavity, and having the in- M M terior space filled with pure water, as in the figure annexed. He gives a rule, though without demonstration, and evidently disfigured or im¬ perfect, for determining the curvature of the two sur¬ faces : “ And by this means,” he subjoins, “ might tele¬ scopes be brought to sufficient perfection, were it not for the different refrangibility of several sorts of rays. But, by reason of this different refrangibility, I do not see any other means of improving telescopes by refractions alone, than that of increasing their lengths.” These remarks appeared to preclude all attempts to improve the construction of the refracting telescope. Brightness and range of sight were sacrificed to distinct¬ ness. Instead of enlarging the aperture, recourse was had to the expedient of increasing the length of the focus. For nice astronomical observations, telescopes were sought of the highest magnifying powers, and their tubes had by degrees been extended to a most enormous and inconvenient size. But the famous Dutch mathemati-Huv: cian Huygens contrived to supersede the use of these in certain cases, by a method which required, however, some address. Many years afterwards the reflecting, or rather catadioptric telescope, of the Gregorian con¬ struction, was executed with tolerable perfection. But a long period of languor succeeded the brilliant age of dis¬ covery. Not a single advance was made in the science of light and colours, till thirty years after the death of ACHROMATIC GLASSES. Airoma- Newton.1 His immortal Principia had not yet provoked tic discussion, and philosophers seemed inclined to regard (asses. t]ie conclusions in the Treatise of Optics with silent and incurious acquiescence. This memorable fact not only evinces the danger of yielding, in matters of science, im¬ plicit confidence even to the highest authority, but shows, amidst all the apparent bustle of research, how very few original experiments are made, and how seldom these are repeated with the due care and attention. The impossibility of correcting the colours in object- glasses of telescopes was therefore a principle generally adopted ; though some vague hopes, grounded chiefly on the consideration of final causes, were still at times en¬ tertained of removing that defect. As the eye consists of two distinct humours, with a horny lens or cornea in¬ terposed, it was naturally imagined that such a perfect structure should be imitated in the composition of glasses. This inviting idea is concisely mentioned by David Gre¬ gory, the nephew of James, in his little tract on Dioptrics. It has also been stated that a country gentleman, Mr Hall of Chesterhall, in Worcestershire, discovered, about the year 1729, the proper composition of lenses by the united segments of crown and flint-glass, and caused a London artist, in 1733, to make a telescope under his directions, which was found on trial to answer extremely well. But whatever might be the fact, no notice was taken of it at the time, nor indeed till very long after, when circum¬ stances had occurred to call forth public attention. The Newtonian principle was first openly rejected, and a discussion excited, which eventually led to a most valu¬ able discovery in optics, by a foreign mathematician of great celebrity and transcendent talents. Leonard Euler was one of those rare mortals who arise, at distant inter¬ vals, to shed unfading lustre on our species. Endowed with a penetrating genius and profound capacity, he was capable of pursuing his abstruse investigations with unre¬ mitting ardour and unwearied perseverance. To him the modern analysis stands chiefly indebted for its prodigious extension; and he continued to enrich it in all its depart¬ ments with innumerable improvements and fine discove¬ ries, during the whole course of a most active, laborious, and protracted life. Unfortunately the philosophical cha¬ racter of Euler did not correspond to his superlative emi¬ nence as a geometer. Bred in the school of Leibnitz, he had imbibed the specious but delusive metaphysics of the sufficient reason, and of the necessary and absolute con¬ stitution of the laws of nature. He was hence disposed in all cases to prefer the mode of investigating a priori, and never appeared to hold in due estimation the humbler yet only safe road to physical science, by the method of experiment and induction. Euler expressed the indices of refraction by the powers of a certain invariable root, and fancied that the exponents of those powers are pro¬ portional for the several rays in different media. Instead of making, in short, the numbers themselves proportional, as Newton had done, he assigned this property to their logarithms. In the Berlin Memoirs for 1747, he inserted a short paper, in which he deducted from his optical prin¬ ciple, by a clear analytical process, conducted with his usual skill, the composition of a lens formed after certain proportions with glass and water, which should remove entirely all extraneous colours, whether occasioned by the unequal refraction of the several rays, or by spherical 201 aberration; and in concluding, he remarked, with high .4chroma- satisfaction, the general conformity of his results with the tic wonderful structure of the eye. Glasses. But this paper met with opposition in a quarter where it could have been least expected. John Dolland, who John Dol- had afterwards the honour of completing one of the finest lancl- and most valuable discoveries in the science of optics, was born in 1706, in Spitalfields, of French parents, whom the revocation of the edict of Nantes had compelled to take refuge in England, from the cruel persecution of a bigoted and tyrannical court. Following his father’s oc¬ cupation, that of a silk-weaver, he married at an early age ; and being fond of reading, he dedicated his leisure moments to the acquisition of knowledge. By dint of so¬ litary application, he made some progress in the learned languages ; but he devoted his main attention to the study of geometry and algebra, and the more attractive parts of mixed or practical mathematics. He gave instructions in these branches to his son Petex-, who, though bred to the hereditary profession, soon quitted that employment, and commenced the business of optician, in which he was afterwards joined by his father. About this time the volume of the Berlin Memoirs, containing Euler’s paper, fell into the hands of the elder Dolland, who examined it with care, and repeated the calculations. His report was communicated by Mr Short to the Royal Society in 1752, and published in their Transactions for that year. Dolland, as might well be expected, could detect no mis¬ take in the investigation itself, but strenuously contested the principle on which it was built, as differing from the one laid down by Newton, which he held to be irrefrag¬ able. “ It is, therefore,” says he, rather uncourteously, and certainly with little of the prophetic spirit, “ it is, therefore, somewhat strange that any body now-a-days should attempt to do that which so long ago has been demonstrated impossible.” The great Euler replied with becoming temper, but persisted in maintaining that his optical principle was a true and necessary law of nature, though he frankly confessed that he had not been able to reduce it yet to practice. The dispute now began to pro¬ voke attention on the Continent. In 1754, Klingenstier- na, an eminent Swedish geometer, demonstrated that the Newtonian principle is in some extreme cases incompati¬ ble with the phenomena, and therefore ought not to be received as an undoubted law of nature. Thus pressed on all sides, Dolland at length had recourse to that ap¬ peal which should have been made from the beginning,— to the test of actual experiment. He constructed a hol¬ low wedge with two plates of glass, ground parallel, in which he laid inverted a common glass prism, and filled up the space with clear water, as in the annexed figure. He now continued to enlarge the angle of the wedge, till the refi’action produced by the water came to counterba¬ lance exactly the opposite refraction of the glass, which 1 The fine discovery of the apparent aberration of the fixed stars, made by our countryman Dr Bradley in 1729, cannot be justly deemed an exception to this remark. It belongs more to astronomy than to optics, and is indeed merely the result, however im¬ portant, of the progressive motion of light, detected near sixty years before by the Danish philosopher Itoemer, combined with the revolution of the earth in her oroit. 102 ACHROMATIC GLASSES.

Glasses. contrary to what he so firmly expected, the external objects appeared glaringly bordered with coloured fringes; as much, indeed, as if they had been viewed through a glass prism with an angle of thirty degrees. It was therefore quite decisive that Newton had not performed his experiment with scrupulous accuracy, and had trust¬ ed rather too hastily to mere analogical inference. But to remove every shadow of doubt from the subject, Mr Dolland, finding that large angles were inconvenient for ob¬ servation, ground a prism to the very acute angle of nine degrees, and adjust¬ ed, by careful trials, a wedge of water to the same precise measure of refrac¬ tion. Combining the opposite refrac¬ tions as before, he beheld, on looking through the apparatus (as here repre¬ sented), their various objects real posi¬ tion, but distinctly marked with the prismatic colours. . In these experi¬ ments, although the mean ray pursues the same undeviating course, the ex¬ treme rays which enter parallel with it emerge from the compound prism, spreading out on both sides. The capital point being completely ascertained, Dol¬ land next tried so to adapt the opposite refractions as to destroy all extraneous colour. This effect he found to take place when the angle of the wedge had been further increased, till the refracting power of the water was to that of the glass in the ratio of five to four. His conclu¬ sive experiments were made in 1757, and he lost no time in applying their results to the improvement of the object- glasses of telescopes. Following the proportion just as¬ certained, he conjoined a very deep convex lens of water with a concave one of glass. In this way he succeeded in removing the colours occasioned by the unequal refraction of light; but the images formed in the foci of the tele¬ scopes so constructed, still wanted the distinctness which might have been expected. The defect now proceeded, it was evident, merely from spherical aberration; for the excess of refraction in the compound lens being very small, the surfaces were necessarily formed to a deep curvature. But this partial success only stimulated the ingenious artist to make further trials. Having proved that the sepa¬ ration of the extreme rays, or what has been since termed the dispersive power, is not proportioned to the mean re¬ fraction in the case of glass and water, he might fairly presume that like discrepancies must exist among other diaphanous substances, and even among the different kinds of glass itself. The charm of uniformity being once dispelled, he was encouraged to proceed, with the confident hope of ultimately achieving his purpose. His new researches, however, were postponed for some time by the pressure of business. But on resuming the inqui¬ ry, he found the English crown-glass and the foreign yel¬ low or straw-coloured, commonly called the "Venice glass, to disperse the extreme rays almost alike, while the crys¬ tal, or white flint-glass, gave a much greater measure of dispersion. On this quarter, therefore, he centred his attention. A wedge of crown and another of flint-glass were ground till they refracted equally, which took place when their angles were respectively 29 and 25 de¬ grees, or the indices of refraction were nearly as 22 to 19; but on being joined in an inverted position, they pro¬ duced, without changing the general direction of the pencil, a very different divergence of the compound rays of light. He now reversed the experiment, and formed wedges of crown and flint-glass to such angles as might destroy all irregularity of colour A _ .; by their opposite dispersions. When this condition was ob¬ tained, the refractive powers of those wedges of crown and flint-glass were nearly in the ratio of three to two, and con¬ sequently the sines of half their angles, or the angles themselves, if small, were as 33 to 19, or nearly as 7 to 4. The rays which enter parallel now escape likewise parallel, but all of them deflected equally from their course. The appearance was rendered still more con- ■ spicuous by repeating the combination of the glass wedges, as in the figure here adjoined. It will be perceived that the pencils of rays which enter at equal distances on both sides of the common junction, must nearly meet in the same point of the axis ; for in small arcs the chords are almost proportional to the arcs themselves. This arrangement, indeed, with the projecting wedge of crown-glass in front, represents ac¬ tually the composition of an object-glass formed of two distinct and opposing lenses, which would produce a similar effect. It was only required to apply a semi-convex lens of crown-glass be¬ fore a semi-concave one of flint-glass, such that the curvature of the former be to that of the lat¬ ter nearly as 7 to 4; but with some modifications in this ratio, according to the peculiar qualities of the glass. [The figure annexed represents this combination.] But the depth of the lenses might be diminished, by giving them curvature on both sides. Thus, if a double convex of crown-glass were substituted, of the same power, and consequently with only half the curva¬ ture on each side; the lens of flint-glass adapt¬ ed to it having, therefore, their common surface of an equal concavity, would need, in order to produce the former quantity of refraction, and consequently to maintain the balance of oppo- site dispersions, a concavity eight times less than before on the other surface. Or if a double concave of flint-glass with half its first depth were SiwMff used, the front convexity of the lens of crown- HHl® glass would be five-sevenths of the former cur¬ vature, as here represented. The surface where the two lenses are united may hence have its curvature changed at pleasure; but every alteration of this must occasion corre¬ sponding changes in the exterior surfaces. In all these cases, the refraction of the con¬ vex pieces being reduced to one-third by the contrary refraction of the concave piece, the focal distance of the compound glass must be triple of that which it would have had singly. But a most important advantage results from the facility of varying the adaptation of the lenses; for, by rightly proportioning the conspiring and counteracting curvatures, it was possible to remove almost entirely the en ors arising from spherical aberration. This delicate pro¬ blem Mr Dolland was the better prepared to encounter, as he had already, in 1753, improved the telescope materially, by introducing no fewer than six eye-glasses, disposed at pi oper distances, to divide the refraction. The research it- sell, and the execution of the compound lens, presented pe¬ culiar difficulties; but the ingenuity and toilsome exertions of the artist were at length, in 1758, rewarded with com¬ plete success. “ Isotwithstanding,” says he, in concluding Acli 'WM_ ACHROMATIC GLASSES. 103 IA roma- his paper, “ so many difficulties as I have enumerated, I I tic have, after numerous trials, and a resolute perseverance, I ( isses. ’Dr0Ught the matter at last to such an issue, that I can construct refracting telescopes, with such apertures and magnifying powers, under limited lengths, as, in the opin¬ ion of the best and undeniable judges, who have experi¬ enced them, far exceed any thing that has been produced, as representing objects with great distinctness, and in their true colours.” The Royal Society voted to Mr Dolland, for his valu¬ able discovery, the honour of the Copley medal. To this new construction of the telescope Dr Bevis gave the name of Achromatic (from a privative, and colour), which was soon universally adopted, and is still retained. The inventor took out a patent, but did not live to reap the fruits of his ingenious labours. He died in the year 1761, leaving the prosecution of the business to his son Pe • Dol- and associate Peter Dolland, who realized a very large fortune by the exclusive manufacture, for many years, of achromatic glasses, less secured to him by the invi¬ dious and disputed provisions of legal monopoly, than by superior skill, experience, and sedulous attention. In 1765, the younger Dolland made another and final im¬ provement, to which his father had before ad- e vanced some steps. To correct more effectually the spherical aberration, he formed the object- glBi glass of three instead of two lenses, by dividing §|||g the convex piece; or he inclosed a concave lens 811f|| of flint-glass between two convex lenses of ff|Bjl crown-glass, as exactly represented in the figure R ill here annexed. He showed a telescope of this improved construction, having a focal length of three feet and a half, with an aperture of three inches and three quarters, to the celebrated Mr Short, who tried it with a magnifying power of fill one hundred and fifty times, and who, superior gjnf to the jealousy of rivalship, and disposed to pa¬ tronise rising merit, most warmly recommended it, and declared that he found “ the image distinct, bright, and free from colours.” What were the curvatures of those distinct component lenses, Dolland has not mentioned, and perhaps he rather wished to conceal them. The Duke de Chaulnes was enabled, however, by means of a sort of micrometer, to ascertain the radii of the several surfaces, in the case of one object-glass of the best composition. He found these radii, beginning with the front lens, to be respectively 311^, 392; 214, 294; 294 and 322^, in French lines, which corresponded, in English inches, to 32'4, 408; 22’2, 306; 30*6 and 33-5. If these measures were cor¬ rect, however, it would follow, that the middle lens of flint-glass was not perfectly adapted to the curvature of the lens of crown-glass placed immediate¬ ly before it. Similar admeasurements have been repeated by others, but the results differ considerably, and no general conclu¬ sion can be safely drawn. There is no doubt that the artist varied his practice, according to the nature of the glass which he was obliged to use. The more ordinary proportions for the curvatures of the com¬ ponent lenses would be represented by a truncated prism, formed with a double cluster of wedges, the outer ones having angles of 25° 53', and 14° 27', and consist¬ ing of crown-glass, and the inner one ma(k °f flint-glass, with an inverted angle of 2i° 3'. Ihese two wedges of crown-glass would pro¬ duce the same refraction, it might be shown, as a single one having an angle of 40° 54'; wherefore this refraction Achroma- will be diminished, by the opposite influence of the wedge tic of flint glass, in the ratio of 49 to 16, or reduced to nearly Glasses- one-third.. Thus was achieved, and fully carried into practical ope¬ ration, the finest and most important detection made in optics since the great discovery of the unequal refraction of the several rays of light. It was drawn forth by a long series of trials, directed with judgment and ingenuity, but certainly very little aided by the powers of calculation. Such a slow tentative procedure was perhaps the best suited, however, to the habits of an artist, and it had at least the advantage of leaving no doubt or hesitation be¬ hind it. On this occasion, we cannot help being struck with a remark, that most of those who have ever distin¬ guished themselves in the philosophical arts by their ori¬ ginal improvements, were seldom regularly bred to the profession. Both the Dollands, we have seen, began life with plying at the loom; Short had a liberal education, being designed for the Scotish church, but, indulging a taste for practical optics, he afterwards followed it as a trade, in which he rose to pre-eminence; Ramsden, whose ingenuity and exquisite skill were quite unrivalled, was bred a clothier in Yorkshire; Tassie, who revived or cre¬ ated among us the nice art of casting gems, was originally a stone-mason at Glasgow; and Watt, who, by his very happy applications of mechanics, and his vast improve¬ ments on the steam-engine, has, more than any other in¬ dividual perhaps, contributed to the great national ad¬ vancement, was early an ivory-turner in that same city,, and still found pleasure, in his declining years, with the amusement of the lathe. We might easily enlarge this catalogue ; but enough has been said to prove the justness of the observation, and it suggests reflections which are not favourable to fixed and systematic plans of education. The theory of achromatic telescopes, embraced in all Subse- its extent, opened a field of abstruse and difficult investi-quent gation. But the English mathematicians at that period, lmPr°ve- though they might appear to be especially invited to thements‘ discussion, very generally neglected so fine an opportunity for the exercise of their genius. They coldly suffered the artists to grope their devious way, without offering to guide their efforts by the lights of science. On the Con¬ tinent the geometers of the first order were all eager to attempt the solution of problems at once so curious and important. For several years subsequent to 1758, the Transactions of the foreign academies were filled with memoirs on the combination of achromatic lenses, dis¬ playing the resources and refinements of the modern ana¬ lysis, by Euler, Clairaut, and D’Alembert,—by Boscovich, Klingenstierna, Kasstner, and Hennert. On this, as on other occasions, however, we have to regret the want of close union between artists and men of science. Those profound investigations are generally too speculative for any real use; they often involve imperfect or inaccurate data; and the results appear wrapped in such comprehen¬ sive and intricate formulae, as to deter the artist from en¬ deavouring to reduce them into practice. We should have thought it preferable, on the whole, not to load the solu¬ tion of the main problem with minute conditions, but to aim at a few general rules, which could afterwards be modified in their application according to circumstances. All this might have been accomplished, without scarcely travelling beyond the limits of elementary geometry. Euler and his adherents at Berlin were still not dis-Euler, posed to abandon his favourite optical hypothesis. It was even pretended that Dolland must have owed his success to a nice correction of spherical aberration, and not to any really superior dispersive power belonging to the 104 ACHROMATIC GLASSES. Clairaut D’Alem¬ bert. Achroma- flint-glass. But that candid philosopher afterwards yield- tic ed to the force of reason and testimony; and, collecting Glasses, ^his various optical papers, he published, in the successive years 1769, 1770, and 1771, a complete treatise on Diop¬ trics, occupying three quarto volumes, which contain a store of ingenious and elegant disquisitions. The last memoir which Clairaut ever wrote related to achromatic glasses. D’Alembert prosecuted the subject with diligence and ardour; and the volumes of his Ma¬ thematical Opuscules, published between the years 1761 and 1767, contain some elaborate dioptrical investigations. Among other conclusions which he deduced from his mul¬ tiplied researches, he proposed a new composition for the object-glass of a telescope, to consist of three lenses, the outmost one being a meniscus of crown-glass, or having a convex and a concave surface, then a meniscus of flint- glass in the middle, and adapted to this, on the inside, a double convex of crown-glass. Of all the continental works, however, which treat of achromatic combinations, TJoscovidi. the tracts of Boscovich, who possessed a very fine taste for geometry, may be held as the simplest and clearest. We cannot help noticing, by the way, a curious theorem of his concerning the form and arrangement of eye-glasses, which would be free from irregular colours. It is, that the correction will be produced by means of two lenses of the same kind of glass, if separated from each other by an interval equal to half the sum of their focal distances. This principle furnishes a very simple construction for the common astronomical telescope, through which the objects are seen inverted. In the annexed figure, the object- glass, as usual, is achromatic, being composed of two con¬ vex lenses of crown-glass, with a concave one of flint- glass fitted between them; but the eye-glass consists of two distinct lenses of crown-glass, both of them convex, and exactly similar, the first having every dimension triple that of the other, and their mutual distance double the focal length of the smaller. Supposing, however, that the errors occasioned by sphe¬ rical aberration were completely removed, the principle of achromatic combination is yet far from being so perfect as it has often been represented. Although the opposite dispersions of the flint and of the crown-glass should bring together the extreme rays, we are not, from this coincidence, warranted to infer that the several interme¬ diate rays would likewise be accurately blended. In fact, a wedge of flint-glass not only separates all the rays much more than a similar one of crown-glass, but divides the coloured spaces after different proportions. While the combined lenses formed of those two kinds of glass give an image entirely free from the red and violet borders, they may still introduce secondary shades of green or yellow, sufficient to cause a certain degree of indistinct¬ ness. The mode of correcting this defect would be, to produce a counterbalance of colours, by conjoining seve¬ ral media endued with different refractive and dispersive powers. In these qualities, crown-glass itself admits of some variation, owing to the measure of saline ingredient; but flint-glass differs widely with regard to its optical pro¬ perties, owing chiefly to the diversified proportion of mi¬ nium or oxyde»oflead which enters into its composition, and partly to the variable admixture of manganese em¬ ployed to discharge the yellow tint occasioned by the lead. Manifest advantages, therefore, would result from a choice combination of three or more varieties of glass, Acf ^ since both the primary and the secondary deviations of colour would be corrected. Without pretending to any^j^ theoretical perfection, every thing really wanted in prac¬ tice would be thus attained. A series of nice experiments on the optical relations of glass could not fail, by their results, to reward the assiduity of the ingenious artist. He would trace and determine the separate influence exerted on the refractive and dispersive powers by soda in the crown-glass, and by minium and manganese in the flint-glass. It is highly probable, that with perseve¬ rance he might discover a vitreous composition better adapted than any yet known for achromatic purposes. It is very generally believed, that the achromatic telescopes now manufactured in London are not of the same excel¬ lence with those first made by Peter Dolland. This de¬ clension of such a beautiful art has frequently been im¬ puted to the baneful operation of a severe and oppressive system of excise. Whether the new mode of charging the duty on glass at the annealing arch has produced any beneficial effects, we are still to learn. An extensive and ingenious set of experiments on the 1 dispersive powers of different liquids, was undertaken, about the year 1787, and successfully prosecuted for some time afterwards, by Dr Robert Blair, for whom there had been recently created,* under royal patronage, the chair of practical astronomy in the University of Edinburgh; one of the very few professorships in that distinguished se¬ minary which have been suffered to remain inefficient and merely nominal. Of these experiments, a judicious ac¬ count was, in 1790, communicated by their author to the Royal Society of Edinburgh, in a paper drawn up with evident ability, but rather too diffuse, and unnecessarily digressive. Dr Blair had a very small brass prism per¬ forated with a hole, which he filled with a few drops of the liquid to be examined, and confined each end by a plate of glass with parallel surfaces. He then applied, in¬ verted to the prism in succession, a number of glass wedges which he had provided of different angles, and observed, when the bars of the window, seen through this compound prism, appeared colourless, the angle of the wedge now expressed the relative dispersive power of the liquid. This way of experimenting was sufficiently sim¬ ple, but a more accurate and expeditious method might have easily been devised. For instance, if the prism, fur¬ nished with a graduated arch, had remained fixed, and a single glass wedge made to turn upon it, and present suc¬ cessive, inclinations to the observer, the refracting angle at which the irregular colours were united could be de¬ duced by an easy calculation. Dr Blair found, by his trials, that muriatic acid, in all its combinations, but par¬ ticularly with antimony and mercury, shows a very great dispersive power. The essential oils stood the next with | regard to that property, though differing considerably among themselves. In Dr Blair’s first attempts to im¬ prove the achromatic telescope, he conjoined two com¬ pound lenses; the one formed with a double concave of crown-glass and a semi-convex of essential oil, and the other composed of a double convex filled with essential oil, of great dispersive power, and of a semi-concave, like¬ wise containing essential oil, but less apt for dispersion. This very complex arrangement seemed, however, to pro¬ duce the desired effect, not only discharging from the image the extreme fringes of red and violet, but ex¬ cluding also the intermediate shades of green or yellow. A simpler combination was afterwards used, requiring merely one liquid, composed of muriatic acid joined with antimony, or the triple salt of that acid united in certain proportions to ammonia and mercury. This liquid, idalius. A C I hroma- being accurately prepared, was inclosed between two tic thin glass shells, to form a double convex lens : asses on the front was applied a semi-convex of crown- glass, and a meniscus of the same material be¬ hind, the whole being secured by a glass ring. ' An object-glass so constructed seemed to per¬ form its office with great perfection, effectually correcting both the primary and the secondary admixture of colours. This kind of eye-glass Dr Blair proposed to denominate aplanatic (from a privative, and vXamu, to err or wander), and he obtained a patent for his invention. The late George Adams, optician in Fleet Street, was intrusted with the fabrication and sale of the telescopes thus constructed. Some of them were said to answer ex¬ tremely well; but, whether from want of activity on the part of the tradesman, or from defect of temper in the paten¬ tee, these instruments never acquired much circulation. It was alleged that the liquid by degrees lost its transpa¬ rency. Indeed we suspect that there is no combination in which liquids are concerned, which can be judged suffi- A c i 10.' ciently permanent for optical purposes. It seems hardly Achroma- possible to preclude absolutely the impression of the ex- tic ternal air; the liquid must, therefore, have a tendency Glasses both to evaporate and to crystallize; and, in the course A • f of time, it will probably, by its activity, corrode the sur- faces of the glass. The manufacture of achromatic telescopes in England furnished, for a long period, a very profitable article of exportation. Even after the introduction of those instru¬ ments was prohibited by several foreign governments, the object-glasses themselves, in a more compendious form, were smuggled abroad to a large amount. In fact, no flint-glass of a good quality was then made on the Con¬ tinent. A very material alteration, however, in that re- French spect, has taken place, at least in France, where the sti-achroma- mulus impressed by the revolution has worked so many tic tele¬ changes, and where ingenuity and science, in most of the scopes- mechanical arts, have so visibly supplied the scantiness of capital. The French now construct achromatic tele¬ scopes, equal, if not superior, to any that are made in England. (b.) ACHTELING, a measure for liquids, used in Germany.

ACIDALIUS, Valens, would, in all probability, have been one of the greatest critics of modern times, had he lived longer to perfect those talents which nature had given him. He was born at Witstock, in Brandenburg; and having visited several academies in Germany, Italy, and other countries, where he was greatly esteemed, he afterwards took up his residence at Breslaw, the metropo¬ lis of Silesia. Here he remained a considerable time, in expectation of some employment; but nothing offering, he turned Roman Catholic, and was chosen rector of a school at Niessa. It is related, that about four months after, as he was following a procession of the host, he was seized with a sudden phrenzy; and being carried home, expired in a very short time. But Thuanus tells us, that his excessive application to study was the occasion of his untimely death ; and that his sitting up in the night com¬ posing his Conjectures on Plautus, brought upon him a dis¬ temper which carried him off in three days, on the 25th of May 1595, having just completed his 28th year. He wrote a Commentary on Quintus Curtins ; also, Notes on Tacitus, on the twelve Panegyrics,-besides speeches, letters, and VOL. II. poems. His poetical pieces are inserted in the Delicice of the German poets, and consist of epic verses, odes, and epigrams. A little work, printed in 1595, under the title of Mulieres non esse homines, i. e. “ That women are not thinking and reasonable beings,” was falsel3r ascribed to him. M. Baillet has given him a place among his Enfant Celebres ; and says, that he wrote a comment upon Plau¬ tus when he was but 17 or 18 years old, and that he com¬ posed several Latin poems at the same age.

ACIDS, in Chemistry, a class of substances which are distinguished by the following properties:— 1. When applied to the tongue, they excite that sensa¬ tion which is called sour or acid. 2. They change the blue colours of vegetables to a red.

If these colours have been previously converted to a green by alkalies, the acids restore them. 3. They unite with water in almost any proportion. 4. They combine with all the alkalies, and most of the metallic oxides and earths, and form with them those compounds which are called salts. It must be remarked, however, that every acid does not possess all these properties ; but all of them possess a sufficient number of them to distinguish them from other substances. And this is the only purpose which artificial definition is meant to answer. See Chemistry. ACIDULfE.

ACILIUS GLABRIO, Marcus, consul in the year of Rome 562, and 211 years before the Christian era, distinguished himself by his bravery and conduct in gain¬ ing a complete victory over Antiochus the Great, king of Syria, at the Straits of Thermopylae in Thessaly, and on several other occasions. He built the temple of Piety at Rome, in consequence of a vow which he made before this battle. He is mentioned by Pliny, Valerius Maximus, and others. ACINODENDRUM, in Botany, the trivial name of a species of Melastoma. ACINOS, in Botany, the trivial name of a species of Thymus. ACINUS, or Acini, the small protuberances of mul¬ berries, strawberries, &c., and by some applied to grapes. Generally it is used for those small grains growing in bunches, after the manner of grapes, as ligustrum, &c. ACIS, in Mythology, the son of Faunus and the nymph Simaethis, was a beautiful shepherd of Sicily, who being beloved by Galatea, Polyphemus the giant was so enraged, that he dashed out his brains against a rock ; after which Galatea turned him into a river, which was called by his name.—The Sicilian authors say, that Acis was a king of this part of the island, who was slain by Polyphemus, one of the giants of iEtna, in a fit of jealousy. Acis, a river of Sicily, celebrated by the poets, run¬ ning from a very cold spring, in the woody and shady foot of Mount .dEtna, for the space of a mile eastward into the sea, along green and pleasant banks, with the speed of an arrow, from which it takes its name. Its waters are now impregnated with sulphureous vapours, though formerly they were celebrated for their sweetness and salubrity, and were held sacred by the Sicilian shep¬ herds.

It is now called II Flume Freddo, Aci, laci, or Chiaci, ac¬ cording to the different Sicilian dialects: Antonine calls it Acius. It is also the name of a hamlet at the mouth of the Acis. ACKERMANN, John Christian Gottlieb, a very learned physician and professor of medicine, was born at Zeulenrode in Upper Saxony, in the year 1756. Hav¬ ing acquired the rudiments of his medical education under the tuition of his father, who was also a physician, he proceeded to Jena and to Gottingen, and studied un¬ der Bal dinger and Heyne. On quitting the latter uni¬ versity, he established himself in practice at Stendal, the numerous manufactories of which place enabled him to contribute many important observations to the translation of Rammazzini’s Treatise of the Diseases of Artificers, which he published in 1780-83. After practising here several years, he was appointed public professor in ordi¬ nary of medicine in the university of Altorf in Franconia, which office he continued to fill with great repute to the time of his death, which took place in 1801. All Dr Ackermann’s works display great erudition. To the his¬ tory of medicine he contributed many valuable articles ; the disquisitions, in particular, on the lives and writings of Hippocrates, Galen, Theophrastus, Dioscorides, Are- taeus, and Rufus Ephesius, which he furnished to Harles’s edition of Fabricius’s Bibliotheca Grceca, are justly esteem¬ ed as masterpieces of critical research. As a practitioner he appears to have possessed no mean talents for obser¬ vation ; though he has been accused, and, it must be ac- A C O knowledged, not without reason, of betraying occasionally a predilection for antiquated hypotheses. Besides various translations of English, French, and Italian medical au¬ thors, which were published, for the most part, previously to his removal to Altorf, the following works have appear¬ ed under his name :—De Trismo Commentatio Medics. 1775, 8vo. 2.

Each warrior was furnished with two. ACLOWA, in Botany, a barbarous name of a species of Colutea. It is used by the natives of Guinea to cure the itch: they rub it on the body as we do unguents. ACME, the top or height of any thing. It is usually applied to the maturity of an animal just before it begins to decline ; and physicians have used it to express the utmost violence or crisis of a disease. ACMELIA, in Botany, the trivial name of a species of Spilanthus. ACNIDA, Virginian Hemp. ACNUA,in Roman antiquity, signified a certain measure of land, about an English rood, or fourth part of an acre. ACO, a town of Peru, in South America. It is also the name of a river in Africa, which rises in the Abyssinian mountains, runs in a south-east course, and discharges itself into the Indian Ocean. ACOEMETAE, or Acoemeti, men who lived without sleep; a set of monks who chanted the divine service night and day in their places of worship. They divided themselves into three bodies, who alternately succeeded one another, so that the service in their churches was never interrupted. This practice they founded upon the precept, Pray without ceasing. They flourished in the East about the middle of the fifth century. There are a kind of acoemeti still subsisting in the Romish church, viz. the religious of the holy sacrament, who keep up a perpetual adoration, some one or other of them praying before the holy sacrament day and night. ACOLUTHI, or Acoluthists, in antiquity, was an appellation given to those persons who were steady and immovable in their resolutions; and hence the Stoics, because they would not forsake their principles nor alter their resolutions, acquired the title of acoluthi. The Acke laai . II Acok AGO AGO 107 i olutiii word is Greek, and compounded of a privative, and xcktvdoi, II way ; as never turning from the original course. Amtius. Acoluthi, among the ancient Christians, implied a jv-^^''pecUiiar order of the inferior clergy in the Latin church, for they were unknown to the Greeks for above 400 years. They were next to the subdeacon; and we learn from the fourth council of Carthage, that the archdeacon, at their ordination, put into their hands a candlestick with a taper, giving them thereby to understand that they were ap¬ pointed to light the candles of the church ; as also an empty pitcher, to imply that they were to furnish wine for the eucharist. Some think they had another office, that of attending the bishop wherever he went. The word is Greek, and compounded of a privative, and xwXuco, to hinder or disturb. ACOLYTHIA, in the Greek church, denotes the office or order of divine service ; or the prayers, ceremonies, hymns, &c. whereof the Greek service is composed. ACOMINATUS, Nicetas, was secretary to Alexius Comnenus and to Isaacus Angelus successively. He wrote a history from the death of Alexius Comnenus in 1118, where Zonaras ended his, to the year 1203, which has gone through many editions, and has been much applaud¬ ed by the best critics. ACONCROBA, in Botany, the indigenous name of a plant which grows wild in Guinea, and is in great esteem among the natives for its virtues in the small-pox. They give an infusion of it in wine. The leaves of this plant are opaque, and as stiff as those of the philyrea; they grow in pairs, and stand on short foot-stalks; they are small at each end, and broad in the middle; and the largest of them are about three inches in length, and an inch and a quarter in breadth in the middle. Like those of our bay, they are of a dusky colour on the upper side, and of a pale green underneath. ACONITI, in antiquity, an appellation given to some of the Athlet^e, but differently interpreted. Mercu- rialis understands it of those who only anointed their bodies with oil, but did not smear themselves over with dust, as was the usual practice. ACONITUM, Aconite, Wolfsbane, or Monks-hood. ACONTIAS, in Zoology, an obsolete name of the an- guis jaculus, or dart-snake, belonging to the order of am- phibia serpentes. ACONTIUM, axe mo v, in Grecian antiquity, a kind of T'/^ along the line. otfuhro- It is not through one series of particles merely that the ugBta on oscillatory motion is communicated. The sounding body 11 having every part of it in a state of agitation, generally acts all round ; but even though it were only to act in one direc¬ tion, the impulse, once begun at the centre, is propagated in all directions; for though only one particle were ori¬ ginally affected, so intimately are they all connected to¬ gether and united into a system by their mutual attrac¬ tions and repulsions, that this cannot advance in any de¬ gree forwards without affecting the particles on each side : these affect what are before and around them; and thus the impulse is communicated, and diffuses itself on all sides. These lateral impressions would appear to be ne¬ cessarily somewhat enfeebled, yet it is one remarkable characteristic of such oscillatory movements, that, like the vibrations of a distended cord, or the oscillations of a pendulum in a cycloid, they are all performed in the same time, however minute or however extended. The lateral impressions, therefore, though ever so feeble, are yet transmitted with the same rapidity as the direct; the sound may be weakened, and we often observe it so;—a speaker, for example, is always best heard in front; the report of a cannon is also loudest in that direction, but still the sound is heard at the very same instant all round. It is owing to this'diffusion of the agitation in all direc¬ tions, the original impression being spread out, not mere¬ ly in concentric circles like the little waves in a pool, but expanding continually, if we can conceive it, into a wider and wider concentric sphere,—it is owing to this that every sound decreases so rapidly as we recede from it, and at last dies away altogether in the distance. It requires a very loud sound to be heard at the distance of a mile, yet we have heard the guns of Edinburgh Castle at the distance of 20 miles; and the noise occasioned by the falls of Niagara is said to be often heard at 60 miles. That this diffusion of the agitating impression is the true cause of the diminution of the sound, is proved in a re¬ markable manner by confining the air on all sides, as in a tube. M. Biot, in his Traite de Physique, gives an account of some very interesting experiments made by himself in the train of cast-iron pipes used for the conducting of water into Paris, and which extended about 2860 feet, thus including in their interior a cylindrical column of air upwards of half a mile in length; at which distance a person standing at one end of the pipes, and speaking within, could be easily heard at the other. “ The low¬ est voice,” says he, “ was heard at this distance so as to distinguish completely the words, and to establish a continued conversation. I wished to ascertain at how low a tone the voice ceased to become audible, and I could not reach it. Words spoken as low as when one whispers in the ear of another were heard and appre¬ ciated; so that if we wished to speak so as not to be understood, there was only one way of doing it, and that was not to speak at all.” It is on this principle that de¬ pends the effect of those tubes which are now in such general use, as modes of communication between distant apartments, in houses and public offices. Hence, also, are performed many amusing tricks with statues or busts, situated in differsmt parts of a room, answering questions, and speaking to one another; the figures being con¬ nected by tubes concealed under the walls or floor, or communicating with an apartment below, in which a speak¬ er is stationed. locit if In regard to the actual velocity with which the impulse n<" of sound advances, it appears, from the most accurate ex¬ periments on the discharge of pieces of ordnance, and marking the interval between the flash and the report, at Acoustics, a distance carefully measured, that in ordinary circum-v--*’'v^-/ stances this amounts to no less than 1130 feet each second, which is nearly equal to the velocity of a cannon ball the moment it issues from the piece. This last is very speedily retarded by the resistance of the air; but sound advances with undiminished velocity. Hence it will travel a mile in a little more than four seconds and a half, or 12-| miles per minute. On this depends an easy method of deter¬ mining in many cases our distance from objects, and which may often prove useful, particularly in military operations. We have only to observe, in seconds, the interval between the flash and report of the cannon or musket, and allow 4^ seconds to every mile, or 1130 feet to every second. Thus, in a house in Lothian Street, directly opposite to the castle of Edinburgh, we have frequently observed a sen¬ sible interval elapse, as the sound of the guns travelled across the intermediate valley, we think about 2" or more ; and the distance in a straight line is about 760 yards, or a little less than half a mile. In the same manner, by ob¬ serving the interval between the flash of lightning and the thunder, we can tell the distance of the point where the electric discharge takes place. It is remarkable also, that all kinds of sound, strong or weak, acute or grave, advance with the same velocity; and this arises from the circumstance already noticed, that all the oscillatory movements in the air, however mi¬ nute or however extended, are performed each in the very same interval of time. This effect was distinctly proved in the experiments made by Biot in the cast-iron pipes already noticed, by playing different airs on the flute at one of the extremities of the tube. Now, it is well known that a musical air is adapted to a certain measure or time, which regulates very nicely the inter¬ vals between the successive notes ; consequently, if any of these were propagated more rapidly or more slowly than others, by the time they reached the ear these would have been confounded with what preceded or fol¬ lowed them; and the air would have appeared quite altered, in place of which it was uniformly regular, and in its natural time ; whence it clearly followed, that all sounds are propagated with equal velocity. The above view of the propagation of sound explains Cause of at once the remarkable phenomenon of the echo, which echoes, arises in every case from obstacles opposing the progress of sound. The agitation in the air, however, though in¬ terrupted by such obstacles, is not destroyed: each aerial particle which strikes against the opposing surface is re¬ flected from it like an elastic ball which strikes against any wall or table. The sound is thus reflected at an an¬ gle equal to the angle of incidence; and it is when a number of these reflected impressions are thrown back to the point whence the original sound issues, by the confi¬ guration of the opposing obstacles, as so frequently hap¬ pens among rocks, walls, &c. that an echo is produced. Hitherto we have considered the air only as the vehicle Air not the of sound, and, without doubt, it is the grand medium ofonly vehU its transmission. Other bodies, however, convey it in a ^ similar manner, and some of them even with much greater rapidity and force. In the liquid element this is proved by the acuteness which fishes display to sounds made in the air, and by many experiments. Professor Robison re¬ lated, that with his head plunged under water, he could hear the sound of a bell, rung also in the water, at the distance of 1200 feet. We have already seen how the tre¬ mor of the piano-forte is communicated to the floor of the apartment; and many other familiar facts show clearly that sound is transmitted through the most solid bo¬ dies. How readily do we hear from one apartment of a 112 ACOUSTICS. Acoustics, house, or from one floor to another. The scratch of a v^''’~v^“'/pin is easily heard from one end of a log to another. A well-known but striking experiment in illustration of the transmission of sound is, to suspend any sonorous body, as a bell, a glass, a silver spoon, or a tuning fork, from a thread, and putting with the finger the extremities of the thread one in each ear;—if the body be then struck against any obstacle, the apparent loudness and depth of the sound are quite surprising. Again, if we shut the ears altogether, we yet feel very sensibly the impression of any sound conveyed through the mouth, the teeth, or the head :—if we put a small stick or rod in the mouth, and touch with the other extremity a watch lying on the table, the beats will become quite audible, though the ears be actually shut. Every noise in the mouth or among the teeth is conveyed internally to the ear in the same man¬ ner. Sound, therefore, is transmitted through liquids and solids, as well as through the air; and indeed, when we consider that the former are quite similarly constituted with the air, being composed of an infinite number of little particles, combined into a system by the same spe¬ cies of attractive and repulsive forces, it is noway sur¬ prising that an impulse communicated to any of these bodies should in like manner be diffused throughout the mass; and this must be by the same species of internal oscillations among the particles. Such being the nature and propagation of sound, and its actual velocity as determined by experiment, it has long been the study of philosophers to reconcile these ef¬ fects with those physical properties of the air and of liquid bodies, which are known from other circumstances, and can be calculated by the laws of mechanics, aided by the powers of mathematical analysis. This subject is inves¬ tigated in the following Part; written, as already men¬ tioned, by Professor Leslie. (c.) Part II. The doctrine of sound is unquestionably the most sub¬ tile and abstruse in the whole range of physical science. It has given occasion, in recent times, to much contro¬ versy and discussion, and has eventually called forth all the mighty resources of a refined and elaborate calculus. Yet an evident obscurity still remains to overcloud the subject. The discrepancies between theory and observa¬ tion have been made entirely to disappear from astronomy, which has at last attained a degree of perfection befitting the sublimity of the science. But some latent suspicions pervade the structure of acoustics, sufficient to disturb that feeling of confidence which is calculated to invigorate our pursuits. Sound con- The impression of sound is conveyed by means of a veyed by a certain tremor or internal agitation, which shoots, with !noraintre’more or less celerity and force, through any substance, whether solid or fluid. Nor is it requisite that the con¬ ducting medium should belong to the class of bodies which are commonly denominated elastic. In fact, all bodies whatever, in the minute and sudden alterations of their form, exert a perfect elasticity, and only seem to want this energy when they undergo such great changes that their component particles take a new set or arrange¬ ment, which prevents the full effect of re-action. It is not every kind of tremulous motion, however, that will excite the sensation of sound. A certain degree of force and frequency in the pulsations appears always ne¬ cessary to affect our sense of hearing. Yet the impression of sound is not confined to the mere external organ: the auditory nerves have a considerable expansion, and sym¬ pathize w ith those of taste and of smell. The only inlet of vision is by that very narrow aperture, the pupil of the eye; but the reception of sound partakes more of theAcoi character of the general sense of feeling, which, though'^" most vivid at the extremities of the fingers, is likewise diffused over the whole surface of the body. The intima¬ tion of the ear is accordingly assisted by the consent of the palate, the teeth, and the nostrils. Fishes hear very acutely under water, though the organ itself lies so concealed in the head as to have long escaped the di¬ ligence of anatomists. It was formerly supposed, that the transmission of im¬ pulse through a solid body is perfectly instantaneous. This formed, indeed, one of the Cartesian tenets, which Newton himself has tacitly admitted. But accurate ob¬ servations have since proved, that motion is always really progressive, and propagated in succession. Professor Leslie has shown that the darting of impact through any substance, whether hard or soft, is accomplished by the agency of the same interior mechanism as that of sound, and has furnished the method of calculating, in some of the more difficult cases, the celerity of transmission. All bodies may be considered as composed of physical All b points, without any sensible magnitude, but connected to-essen gether by a system of mutual attraction and repulsion.elasti When those integrant particles are compressed by exter¬ nal violence, a repulsive force is exerted to regain their first position; or if they be dilated, a corresponding at¬ traction now draws them back to their neutral site of equilibrium. We may further presume, that in solids these constituent forces are confined to the proximate particles only, but that in the case of liquids or other fluids they embrace the particles in their near vicinity, and include a sphere of action varying in its extent. Hence, the former suffer disruption, without bending or giving way to powerful pressure ; while the latter, acting by a sympathetic union, gently recede and take a new arrangement. In fact, the attribute of hardness applied to body is only a relative, and not an absolute quality; in the inferior degrees it relapses into softness, and softness again passes through interminable shades to the most yielding fluidity. The application of heat, by enlarging the sys¬ tem of internal connection, generally promotes softness, and heightens the degree of fluidity itself. The effect is conspicuous in the increased flow from a capillary sy¬ phon, when kept warm. But even liquids, when struck with a blow so rapid and sudden as to preclude the sympathy of their adjacent molecules, will assume all the character of the hardest substances. This fact has a familiar illus¬ tration in the play of duck and drake; but it is beauti¬ fully exemplified in the successive rebounds made by can¬ non-shot, from the surface of the sea. In confirmation of the remark, we may quote a very singular and curious circumstance, mentioned by travel¬ lers, relative to the method of catching fish, which is suc¬ cessfully practised in some of the more northern coun¬ tries. I he hardy peasant, when the smaller lakes and rivers of Lapland or Siberia are completely frozen over, as soon as he observes, through the clear ice, a fish, per¬ haps at a considerable depth, but lying close to the bot¬ tom, strikes a smart blow against the firm surface, and the impulse sent through the vertical column of water instant¬ ly stuns or kills his prey, which he draws up by a large hook let down through the hole just mad.e in the ice. If we conceive a conducting substance to be struck at one extremity, the proximate particles, yielding at first to the impulsion, will again expand themselves, like the recoil of a spring, and press against the next particles in the chain. I he vibratory commotion will thus be con- veyed, by a successive transfer of impressions, along the whole series of physical points. Analogous also to the A C O U A'ustics. oscillations of a spring or a pendulum, this multitude of ICj''/'^concatenated internal pulses, whatever be the force or ex¬ tent of agitation, will constantly be performed in the same instants of time. The celerity of transmission must de¬ pend on the elasticity of the medium compared with its gravity. This estimate is most readily obtained by de- TUi ulus termining what may be called the modulus of elasticity, of asti- or the height of a column of the same density as the con- ,cil ducting substance, whose weight would measure that elasticity; or, to speak more precisely, that the thousandth part of such a column, for instance, should be equivalent to the repulsive force corresponding to a condensation of one thousandth part in the vibrating body. It may be demonstrated from the principles of dynamics, that the celerity of the transmission of ifnpulse or sound through any medium is equal to what a falling body would ac¬ quire in falling through half the height of the modulus of elasticity. Hence this celerity for each second will be expressed in English feet by multiplying the square root of half the modulus by 8, or by extracting the square root of the modulus multiplied by 32. lejrity of Mr Leslie has pointed out a very simple method for as- liwd certaining the modulus of elasticity in the case of solid (fiflrent ro(^s or P'an^s’ ^7 observing, when they are laid in a sol: hbrizontal position, with their ends resting against two bolts. props, the swag or curvature which they take. By an ex¬ periment of this kind, he found that Memel fir had a mo¬ dulus equal to 671,625 feet. Wherefore, an impulse would shoot through the substance of a deal-board with the velocity of 4,636 feet each second, or about four times the rapidity of sound. Professor Chladni, who has thrown so much curious light on the convoluted curves formed by vibrations spreading along the surface of solid bodies,, inferred, from a very different procedure,—from the musi¬ cal note which a bar of the substance emits when struck, —the celerity of the transmission of sound through iron and glass, which he reckoned for both at 17,500 feet, or above three miles each second, being more than fifteen times swifter than the ordinary communication through the atmosphere. The rate with which the tremor of sound is transmitted through cast-iron, was very lately ascertained, from actual experiment, by the ingenious M. Biot. This philosopher availed himself pf the opportunity of the laying of a sys¬ tem of iron pipes, to convey water to Paris. These pipes were about eight feet each in length, connected together by narrow leaden rings. A bell being suspended with¬ in the cavity, at one end of the train of pipes, on striking the clapper at the same instant against the side of the bell and against the internal surface of the pipe, two dis¬ tinct sounds were successively heard by an observer sta¬ tioned at the other extremity. In these observations M. Biot was often assisted by the late M. Malus, who has, too soon for the progress of science, been hurried away by death, after having opened the delicate discovery of the polarization of light. With a train of iron pipes of 2550 feet, or nearly half a mile in length, the interval between the two sounds was found, from a mean of two hundred trials, to be 2*79 seconds. But the transmission of sound through the internal column of air would have taken 2-5 seconds; which leaves *29" for the rapidity of the tremor conducted through the cast-iron. From other more direct trials, it was concluded that the exact interval of time during which the sound performed its passage through the substance of the train of pipes, amounted only to 26-100th parts of a second; being ten to twelve times less than the ordinary transmission thi'ough the atmo- sphere. Except the observations of M. Hassenfratz, in the fa- VOL. II. S T I C S. 113 mous subterranean quarries which extend under almost the Acoustics, whole of Paris, we are not acquainted with any attempts that have been made to measure the elasticity of stone or brick. Yet sound is conveyed through these materials with great effect. The rattling of a carriage on the street spreads a very sensible tremor along the most so- licj buildings and the stateliest edifices. If a large stone be rubbed against the outside of the wall of a house, it will occasion within doors a strange rumbling noise. A miner will strike his pick against the side of a long gal¬ lery, when he wishes to give intimation to his companion, who listens at the other extremity. But stones or bricks, without being directly excited, may yet form a part of the chain which transmits sound, by receiving the tre¬ mulous impressions from the air on the one side, and de¬ livering them again to that fluid on the other. We all know how easily the voice is heard through a thin parti¬ tion. The mode of obstructing the passage of sound is, either to employ very thick masonry, or to interrupt the facility of communication and transfer, by means of sub¬ divisions opposed. Hence another distinct use of lath and plaster. Experiments on the elasticity of stones and other articles of building are not only curious, but of real importance ; for, in many cases, their efficient strength must depend on their fitness to resist incidental impres¬ sions. This consideration is peculiarly necessary in se¬ lecting and combining the materials employed in the con¬ struction of bridges. Respecting the elasticity of water and other liquids, Supposed our information is more satisfactory and complete. Itincompres- was long held as an axiom, that the substance of water °f absolutely incompressible. Yet the experiments on which waten this belief was grounded would, if weighed attentively, point to an opposite inference. On such a subject it were idle to cite Lord Bacon, whose credulity and igno¬ rance of mathematical science betrayed him so often into false or shallow conclusions. The philosophers of the Florentine academy del Cimento tried the compression of water in three different ways, which are described in the account of their experiments printed in 1661. L Hav¬ ing provided two glass tubes terminated by hollow balls, they filled the one partly and the other to excess with pure water, and joined the tubes hermetically, so as to form one piece. Then applying heat to the first ball till the water boiled, they forced its vapour to press against the column in the other stem. But no contraction of the fluid took place, though a copper ball was afterwards substituted; and when the action of the heat was still far¬ ther urged, the tube at last burst with violence. 2. Into a glass tube, immediately above six pounds of water, they introduced eighty pounds of quicksilver, without causing any diminution of volume. 3. Their most noted experiment was, having filled a hollow silver ball with water by a small hole, afterwards soldered accurately, to give it a few smart blows with a hammer ; when, far from suffering compression, the water was seen to ooze or spirt from the pores, as they imagined, of the silver. Mr Boyle, whose practice it was generally to repeat the more striking experiments made on the Continent, had a round tin or pewter vessel filled carefully with water, and tightly plugged : the blow of a wooden mallet beat it flat, but on piercing the tin with the point of a small nail, the confined water instantly sprung to the height of two or three feet. About the year 1752, Dr Peter Shaw, who read public lectures in London, exhibit¬ ed a stout copper ball of four inches in diameter, and fill¬ ed with water by a small orifice, into which a screw was fitted, and forced to enter by turning an iron arm or lever; the globe was partly opened by this enormous p 114 ACOUSTICS. Acoustics, squeeze, and the water spouted from the crevice as from a fountain. , These experiments all concur to show that water is capable of sustaining an immense pressure without under¬ going any very sensible contraction; but they prove, at the same time, the actual existence of such a contraction, since the projecting of the water, after a crack has once begun in the vessel that confines it, could only proceed from the evolution of an internal repulsive force. Divers, accordingly, at considerable depths under water, hear dis¬ tinctly the collision of two stones, or the remote ringing of a bell. Authentic instances are mentioned of sounds being transmitted audibly more than two miles through that fluid. Compres- The compressibility of water was first demonstrated by Ability of the ingenious Mr Canton in 1762, by a very simple and monstrat" conclusive experiment. To a glass ball of rather more ed by Mr t^ian an an(^ ^a^ *n diameter, he joined hermetically Canton. a tube about four inches long, and having a bore equal to the hundredth part of an inch. The relative capacity of this ball and of the stem he ascertained by introducing mercury, and weighing nicely its separate portions. The stem was then marked by the edge of a file into divisions, corresponding each to the hundred thousandth part of the whole capacity of the ball. This instrument was now filled with distilled water, carefully purged of its adher¬ ing air, and placed under the receiver of a pneumatic machine : on producing an exhaustion, the water appeared . constantly to swell, rising four divisions and three-fifths in the stem, or a space nearly equal to the mercurial ex¬ pansion corresponding to half a degree of heat on Fahren¬ heit’s scale. In a condensing engine, the water sunk just as much, for each additional pressure of an atmosphere,— the bulb remaining always at the same temperature, or at the fiftieth degree of Fahrenheit. Since the stem was left open, the pressure exerted by the air, both on the inside and the outside of the instrument, must in all cases have been precisely the same ; and consequently, the glass had no disposition to alter its figure, and modify the results. The contraction or expansion produced was, therefore, confined wholly to the body of water and to the thin shell of glass, of which indeed the influence might be rejected as insignificant. It was hence decided that the purest water suffers a visible concentration, or a diminu¬ tion of its volume, under a powerful compression. But, in the course of his experiments, Mr Canton observed a curious circumstance, that water is more compressible in cold than in warm weather. Thus, the contraction, under a single incumbent atmosphere, amounted to 4*9 divisions when the thermometer stood at 34°, but was only 4-4 divisions when the heat rose to 64°. This singular fact might afford room for speculation ; but it were better, in the mean while, to repeat the experiment again with more delicacy, and on a greater scale. Compressi- The compression of some other fluids was likewise bility of measured in the same way. The contraction, under the fluids. wciSht of an atmosphere, and at the ordinary temperature, amounted, in millionth parts of the entire capacity of the ball, to sixty-six with alcohol, to forty-eight with olive oil, to forty with sea-water, and only to three when mercury was opposed. We may therefore estimate, in round num¬ bers, the modulus of elasticity belonging to those different substances as under: Alcohol 580,000 English feet. Distilled water 700,000 Olive oil 730,000 Sea-water 780,000 Mercury..... *....800,000 In liquids of so distinct a nature, we should have expected a greater diversity in their elastic power ; nor is it easy to Acoust conceive on what conditions or habitudes that quality actually depends. The elasticity of a body, like its other constitutional properties, may result from the peculiar in¬ ternal structure, or the arrangement of the integral mole¬ cules. v Some experiments on the compressibility of water have been since performed with more striking effect, but not equally exempt from all objections. In 1779, Professor Zimmerman of Brunswick printed a short account of someZimnie trials made by him and Abich, director of the salt-mines, man. with a press of a particular construction, consisting of a tight cylinder of very thick brass, with a piston nicely fitted, to be pushed down by means of a long lever, at whose extremity different weights were appended, liain- water being introduced into the cavity, was subjected to an enormous pressure, equivalent to that of 313 atmo¬ spheres, and had its volume then diminished between one thirty-fifth and one thirty-sixth part. This quantity gives, for the effect of a single incumbent atmosphere, a conden¬ sation amounting to seventy-five millionth parts, instead of forty-six, as found by Mr Canton. The excess was no doubt owing to the distention of the brass cylinder, which, with all its strength and solidity, would yet partially yield to the action of such prodigious force. This circumstance renders the experiment somewhat unsatisfactory, and the influence of friction must likewise affect the accuracy of the calculation. The effect of such distention is easily witnessed in the case of glass. If a large bulb of a thermometer be sud¬ denly squeezed between the finger and the thumb, the mercury will start up in the stem perhaps several degrees, and will again sink as quickly after the pressure is remov¬ ed. To prevent any derangement from communication of heat, the hand may be covered with a thick glove. But the fact can be shown in a less exceptionable way: Let a mercurial thermometer, with a large bulb and a long stem, be first held upright, and then immediately inverted; be¬ tween these two positions the column of mercury will de¬ scend through a visible space. This apparent change of | volume has been hastily supposed by some experimenters to mark the compressibility of mercury, which could not be sensible but under the action of a column of incompar¬ ably greater height. It would be most desirable to institute a new set of ob¬ servations on the condensation of different substances, by means of Bramah’s hydraulic press, which is a far more Eramab perfect machine, and scarcely subject at all to the dis-hydrauli turbance of friction. Having once ascertained the dis-P™5, tention of the metallic cavity from pressure, it would be hence easy to correct all the other results. This mode of experimenting promises also the important advantage of enabling us to determine, with ease, the compressibility of solids themselves. It would only be required to give those bodies a cylindrical form nearly adapted to the cavity, and to fill up the interstice with water, or rather with mercury. Tlhe contraction which the thin sheet of fluid would undergo, being deducted from the whole con¬ traction, would exhibit the contraction suffered by the solid nucleus. . From all these investigations we may gather, that an Celerity impulse, or a sonorous tremor, would shoot through a body sound of fresh water with the velocity of about 4,475 feet each through second, being four times swifter than the ordinary flightwater’ of sound in the atmosphere. Through the waters of the ocean, the transmission of sound would be still more rapid, by a seventeenth part. It hence follows, that a, violent commotion, excited under that vast mass, might reach from pole to pole in the space of three hours and twenty minutes. ACOUSTICS. A lustics. The swell of the sea is accordingly always observed to precede the coming storm. The shocks of the famous earthquake at Lisbon, in 1755, were partially felt at very distant points of the ocean, as far even as the West Indies, but after a considerable interval of time. Respecting the power of ice to conduct sound, we pos¬ sess not sufficient data for the solution of the problem. The Danish philosophers are indeed said to have lately performed experiments of this kind on a very extensive a scale, along the frozen surface of the Baltic. We are not tlflugh acquainted with the precise results ; but it seems probable, ki from various analogies, that ice has nearly the same faculty of transmission as water itself. If a heavy blow be struck against any part of the frozen surface of a large pool or lake, a person standing at a wide distance from the spot will feel, under foot, a very sensible tremor, some con¬ siderable time before the noise conveyed through the at¬ mosphere has reached his ear. It is asserted, that the savage tribes who rove on the icy steppes of Tartary can readily distinguish, from afar, the approach of cavalry, by applying their head close to the frozen surface of the ground. Pibaga- But the proper and ordinary vehicle of sound is our 11,1 ot atmosphere. Aristotle, deriving his information probably ■’r , from the tenets of the Pythagorean school, seems to have Ihlatmo- accluired tolerably just notions of the nature of sound and spl're. °f the theory of harmonics. The language of that philo¬ sopher was so much corrupted, however, and disguised by ignorant transcribers, that Galileo, who not only studied music as a science, but practised it as a delightful art, may be fairly allowed to have rediscovered those general doctrines. Mersenne and Kircher afterwards made a variety of most ingenious experiments, which, though rather overlooked at the time, tended greatly to extend the science of harmony. But it was reserved for the ge¬ nius of Newton to sketch out the true theory of sound, ■•flton’s In his Principia he explained the origin of aerial pulses, ■-uy °f jjy a gne application of dynamics, conducted with his gai n 'd'1" usual sagacity, he succeeded in calculating their celerity so d. transmission. The solution which he has given of this intricate problem is far, however, from being unexception¬ able in the form and mode of reasoning. Instead of at¬ tempting to embrace all the conditions affecting the pro¬ blem, in a differential equation, for which, indeed, his fluxionary calculus was not yet far enough advanced, he pro¬ ceeds less boldly, and only arrives at the conclusion by an indirect process and a sort of compensation of errors. His investigation of the progress of sound through the air is chiefly drawn from the analogy of the motion of waves along the surface of water. This comparison greatly assists our conceptions, but it fails in a variety of essential points. Newton further assumed the rising and subsiding of waves to be a reciprocating motion, similar to that of the oscillations of a fluid contained in a wide and long tube, with its ends turned upwards. On this supposition, it was not difficult to prove, that those alternating move¬ ments would correspond to the vibrations of a pendulum of half the length of the tube. Transferring the inference, therefore, to the undulations of a fluid, it followed, that the space between two consecutive waves would be de¬ scribed during the sweep of a pendulum having a length equal to this interval. But the conclusion does not very well accord with the phenomena. That a wave travels with a velocity as the square root of its breadth, may be nearly true; and that its reciprocating motions, whatever be the height, are all performed in the same time, is a ne¬ cessary consequence of the great principle in dynamics first pointed out by Huygens and Hooke,—that when the effort to restore equilibrium is proportioned to the quan¬ 115 tity of displacement, the alternations of figure are con-Acoustics, stantly isochronous. But the velocity of the undulating progression, as calculated from those principles, will not be found to correspond with actual observation. Newton was apparently sensible of this disagreement, and would consider his proposition as only an approximation to the truth; assigning as the cause of discrepancy, that the particles of water do not rise and fall perpendicularly, hut rather describe arcs of a circle. The great defect of the hy¬ pothesis, however, consisted in supposing all the parts of a wave to rise up and sink together in the same spot. The fact is, that the fore part of a wave is always in the act of ascending, while the hinder part of it is as constantly sub¬ siding ; Avhich combined but contrary movements, with¬ out actually transferring any portion of the water, give an appearance of progressive advance to the swell. In extending this theory to the propagation of sound, Newton was, on the whole, more successful. It resulted from his investigation, that the aerial pulses fly uniformly, spreading themselves equally on every side, and with a celerity equal to what would be acquired by a body in falling through half the height of the modulus of the air’s elasticity. This modulus, or the altitude of a column His correc- of air, of uniform density, and whose pressure would be A011 °f the equivalent to the ordinary elasticity of that fluid, was com- th601-!- puted in the first edition of the Principia, which came out in 1687, on the supposition that water is 850 times denser than air, mercury 13-h times denser than water, and that the mean height of the barometer is thirty English inches. The modulus of elasticity, or the height of an equiponde¬ rant column of air, was therefore estimated at 29,042 feet, which gave 968 feet each second for the celerity of the transmission of sound through the atmosphere. In the next edition, which did not appear till twenty-six years thereafter, the computation of the modulus was somewhat altered, but certainly not rendered more correct. Assum¬ ing the same standard of barometric height as before, and supposing mercury to be 13§ times heavier than water, and water 870 times heavier than air, the modulus would be 29,725 feet, to which the corresponding velocity of sound is 979 feet in the second. In these successive estimates, there is perhaps betrayed some desire to magnify the result, yet without nearly ap¬ proaching to the amount of actual observation. Dr Der- ham had recently determined, from repeated trials made with care, that the ordinary flight of sound is at the rate of 1142 feet each second; and Newton endeavoured, by some very strained hypotheses, to accommodate his calcu¬ lation to this correct measure. 1. He supposes the particles of air to be perfectly solid spherules, whose diameter is the ninth part of their mutual distance. Sound, being in¬ stantaneously communicated through these, would thus have its velocity increased by one-ninth, or 109 feet, or brought up to 1088 feet in the second. 2. He next assumes, that the particles of vapour concealed in the air, and augmenting the common elasticity without partaking of the impression of sound, amount to a tenth part of the whole. This would increase the celerity of the sonorous pulse in the subduplicate ratio of 10 to 11, or as 20 to 21 nearly, and consequently advance the last measure from 1088 to 1142 feet. But these random and fanciful conjectpres hardly require Remarks any serious consideration. What may be the size of the on these ultimate particles of air, or whether they have any sensible c.orrec- magnitude at all, we are utterly without the means of de-tlons- termining. There appears no limit, indeed, to the degree of condensation of which the air is capable, but what pro¬ ceeds from the imperfection of the engines employed for that purpose. Nay, supposing so large a proportion of ab- 116 ACOUSTICS. city of sound. Acoustics, solute matter to exist ip the composition of our atmosphere, it really would not affect the result, since the transit of §ound, as we have showh, is necessarily progressive, even through the most solid substance. To this principle there could be no exception, unless the particles of air were held to be mere atoms, incapable of further subdivision,—in short, without actual magnitude, and therefore bearing no relation whatever to the space in which they float. The second hypothesis advanced is still more insufficient to rectify the general conclusion. That moisture, in its latent or gaseous form, is united with the air, will be granted; but it by no means constitutes so notable a share of the fluid as Newton has assumed, scarcely exceeding, at the ordinary temperature, perhaps the five-hundredth part of the whole weight. But this diffuse vapour could not in the least derange the original calculation; for, being always combined with the air, the measure of elasticity assigned by experiment was really that of the compound fluid which forms our atmosphere. Rectified We are now enabled, by the help of more perfect data, calculation to rectify the modulus of atmospheric elasticity, or the height of a homogeneous and equiponderant column of the fluid. From the observations made with barometrical measurements, it appears that such a column, exerting a pressure equivalent to the elasticity of the air, has, at the limit of freezing water, an altitude of 26,060 feet, and con¬ sequently, that the modulus would, at an ordinary tempera¬ ture of 62° by Fahrenheit, amount to 27,800 feet. This corrected estimate gives only 943 feet each second for the celerity of sound. And since the elasticity of the medium is exactly proportioned to its density, the result is the same, whatever be the rarefaction or condensation of the air, so long as its temperature continues unaltered. The flight of sound is hence as rapid near the surface as in the higher regions of the atmosphere. It is the conjunction of heat alone that will increase the celerity of transmission, by augmenting the elasticity of the medium without add- fng to its weight. The acceleration thus produced must amount to rather more than one foot in the second for each degree by Fahrenheit’s scale. Such a difference ought to be perceptible under the torrid zone. But the rate of the transmission of sound must vary in different gases, after the inverse subduplicate ratio of their densities. Thus, through carbonic gas, the communica¬ tion of the tremor would be about one-third slower than ordinary; but through hydrogen gas, which is twelve times more elastic than common air, the flight would very nearly exceed three and a half times the usual rapidity. An admixture of this gas with the atmosphere would, therefore, greatly accelerate the transmission of sound. The joint combination of heat and moisture, by heighten¬ ing the elasticity of the air, must likewise produce a simi¬ lar effect. These inferences are'confirmed by observation, as far as it extends. The velocity of sound was determined with considerable accuracy, and on a great scale, by Cassini and Maraldi, while employed in conducting the trigono¬ metrical survey of France. During the winter of the years 1738 and 1739, these astronomers repeatedly dis¬ charged, at night, when the air was calm and the tempera¬ ture uniform, a small piece of ordnance, from their station on Mont Martre, above Paris, and measured the time that elapsed between the flash and the report, as observed from their signal tower at Montlehery, at the distance of about eighteen miles. The mean of numerous trials gave 1130 feet for the velocity of the transmission of sound. About the same time, Condamine, who was sent with the other academicians to ascertain the length of a degree in Peru, took an opportunity of likewise measuring the Rate of transmis. sion through different gases. Experi¬ ment in France, and in America. celerity of sound, at two very different points. He found Acoust this was 1175 feet on the sultry plain of Cayenne, and only'^v- 1120 feet on the frozen heights of Quito. It was obvious, therefore, that the rarefaction of the air in those lofty regions had in no degree affected the result. Compared with what had been observed in France, the velocity of the aerial pulses was somewhat diminished at Quito by the prevailing cold, but was, on the other hand, consider¬ ably augmented by the excessive heat and moisture which oppress Cayenne. But the "difference, amounting indeed to one-fifth of the whole, between the velocity of sound as deduced from theory, and as determined by actual experiment, still ap¬ peared very perplexing. This want of congruity was the more felt, since the Newtonian system of gravitation, after maintaining a long struggle with the adherents of the Cartesian philosophy, had at last obtained the undisput¬ ed possession of the Continent. Its triumph was insured by the admirable dissertations on the subject of tides, transmitted to the Academy of Sciences at Paris in the year 1740, when our celebrated countryman Maclaurin had the honour of sharing the prize with Euler and Daniel Bernoulli. The law of attraction received, indeed, a temporary shock a few years afterwards, from the re¬ sult of the investigation which Clairaut first gave of the lunar inequalities; but, on resuming his analysis of the problem, and computing the values of the smaller terms of the formula, that great geometer obtained, in 1752, a final product, exactly conformable to the best astronomi¬ cal observations; and the solidity of the Newtonian sys¬ tem was henceforth placed on the firmest foundation. It was therefore peculiarly desirable to examine like¬ wise the justness of the hydrodynamical conclusions of Newton. The propositions concerning the propagation of sound were perhaps justly considered as the most ob¬ scure part of the whole Principia. Some of the first-rate mathematicians abroad, particularly D’Alembert and John Bernoulli, declared their utter inability to comprehend such intricate and disjointed demonstrations. At last the problem of sonorous pulses was attacked directly, and in its full extent, by the late Count Lagrange, whose Invest! death, although at a ripe age, will be lamented as a mostfl°nof severe loss to mathematical science. That illustrious §ranSe' geometer shone forth at once like a meteor, and before he had completed his twenty-third year he gave a rigorous and profound analysis of the propagation of sound through the atmosphere, in the first volume of the Turin Memoirs, which appeared in 1759. “ He pointed out some mistakes that even Newton had committed in the reasoning; but mistakes which, by a haj^py compensation of errors, did not affect essentially the results. Advancing from these discussions, he assigned the dynamical conditions of un¬ dulation, which, after the proper limitations, were reduced to an equation involving partial differences of the second order. But this refined branch of analysis, invented by D’Alembert and Euler, is still so imperfect, that, in order to integrate the final expression, it had become requisite to omit the higher powers of the differentials. Yet after all this display of accurate research and skilful adaptation of symbols, followed by a lax and incomplete calculus, the same conclusion was obtained as that which Newton had derived chiefly from the force of analogy and sagacity of observation; and philosophers were thus obliged to sub¬ mit, and to content themselves with recording the va¬ riance between theory and experiment in regard to the celerity of sound, or with referring that discrepancy to some extraneous influence.” (Edinb. Review, vol. xv. p. 431.) V M. Poisson, one of those interesting men whose native A C O U Ac istics. genius has surmounted all the obstacles of fortune, very lately attempted a more complete analysis of the propa¬ gation of sound, in the Papers of the Polytechnic School. The final equation is more fully expressed, and its integra¬ tion is pushed some few steps farther; but still the result is precisely the same as before. The skill and precaution displayed in framing the conditions of the problem are afterwards mostly abandoned in the various simplifications adopted to arrive at the conclusion, lelifica- A very ingenious and apparently satisfactory method Uotof the of reconciling theory with observation, in the estimate of thdy by the transmission of sound, was not long since suggested Lajace. ^ the celebrated Count Laplace. If the heat contained in air had, at every state of the density, been united con¬ stantly after the same proportion, the elasticity resulting from the infusion of this subtile and highly distensible element would invariably accord with what observation assigns to the compound aerial fluid. But the capacity of air, or its aptitude to retain heat, varies with its internal condition; being increased by rarefaction, and propor¬ tionally diminished by condensation. When air is com¬ pressed, therefore, it liberates a portion of its heat; and when it undergoes dilatation, it becomes disposed to abstract more heat from the adjoining bodies. Till the equilibrium of heat is restored, the air will be sen¬ sibly warmer after each act of compression, and colder when suffered to dilate. If the shock given to a portion of air be very sudden and violent, the quantity of heat evolved from it is profuse and powerful. On this princi¬ ple, M. Mollet, member of the academy of Lyons, led by some facts noticed by artists who manufactured wind- guns, first constructed, in 1804, the curious instrument for producirig fire by the rapid condensation of air confined in a tube. But such evolution of heat must besides augment the elasticity of the air, as the contrary abstrac¬ tion of it will, in a like degree, diminish that force. At every sudden alteration of density, therefore, a new power is infused, which had not entered into the ordinary and undisturbed estimate of the air’s elasticity. Conse¬ quently, from this consideration alone, the aerial pulses must shoot with some greater celerity than calculation as¬ signs, because the particles of air, which are suddenly condensed, have their elasticity further augmented by the portion of heat evolved, while the corresponding particles, which are simultaneously dilated, have their disposition to contract likewise increased, by the momentary preva¬ lence of cold. jiina- The principle advanced by Laplace must therefore jif this have a real operation, tending to reconcile the calculated coi fction. velocity of sound with that which is deduced from expe¬ riment. The only question is, how far its influence could actually extend. But, according to the formula given in Leslie’s Elements of Geometry, p. 495, a condensation equal to the 90th part of the volume of air would occasion the extrication of one degree of heat by Fahrenheit’s scale. Now, since each degree of heat enlarges the bulk or augments the elasticity of the air by the 450th part, it follows, that the heat, extricated by sudden impulse, will communicate to the air a momentary additional spring, amounting to one-fifth of the whole elastic force. Where¬ fore the celerity of sound would, by that influence, be in¬ creased in the subduplicate ratio of five to six, or nearly as 21 to 23 ; which gives an addition of only 90 feet each second to the whole quantity, bringing it up to 1033 feet. The correction is thus insufficient, not amounting to half of the discrepancy which it was its object to reconcile. It may be suspected, therefore, that some inaccuracy or omission infects the investigation itself. Till the inte¬ gral calculus has arrived at much greater perfection, it STICS. ]17 will often be requisite for the analyst, in the solution of Acoustics, dynamical problems, to descend from his elevation, andv-*“v'%fc'/ seek to simplify the differential expressions by a sober and judicious application of the principles of physics. “ Imagine a string of particles, or physical points, A, B, C, D, E, F, &c. in a state of rest, or mutual balance. If A were pushed nearer to B, and then suddenly abandon¬ ed, it would recoil with a motion exactly similar to the oscillation of a pendulum. The time of this relapse might easily be determined, from a comparison of the force of gravity with that of elasticity, or from the number of par¬ ticles contained in a column of equipoise. The minute interval between the adjacent particles, being now divided by the duration of each fit of contraction, will give the velocity with which the vibratory influence shoots along the chain of communication. This simple investigation leads still to the same result as before. But it proceeds on assumptions which are evidently incorrect; for it sup¬ poses the pulses to follow each other in accurate succession, every contraction terminating as the next begins. Since the particles, however, do not exist in a state of insulation, while B repels A, it must likewise press against C ; and C, in its turn, must gradually affect D. Before the contrac¬ tion of A and B is completed, that of B and C is therefore partially performed; and this anticipated influence may even extend to the remoter particles. Nor is the system of mutual action at all materially disturbed by such anti¬ cipations. Each pulsation is performed in the same way as if it were quite detached; only the succeeding one is partly accomplished before the regular period of its com¬ mencement. The velocity of aerial undulation is in this way much accelerated.” (Edinb. Rev. vol. xv. p. 433.) Each successive movement among the particles may be viewed as produced by a force not regularly decreasing, but partaking of the uniformity which obtains in projec¬ tion. Hence the velocity of sound is intermediate be¬ tween that derived from theory and that with which air would rush into a vacuum. But the arithmetical mean between 943 and 1334 feet is 1138^-, and the geometrical is 1121! feet; neither of which differs much from 1130 feet, the quantity determined by actual experiment. After the last correction, however, proposed by M. Modifica- Laplace, for adjusting theory with observation relative totions re- the celerity of the transmission of sound, the difference quired in will not perhaps be regarded such as longer to present any fee the°ry serious obstacle ; especially when the coincidence appears01 sounc " closer than what generally attends the theoretical deduc¬ tions concerning the motions of fluids. The remaining difficulties affecting the subject refer chiefly to the way in which the aerial pulses are propagated, and the modi¬ fications which they are afterwards capable of receiving. 1. No sensation is ever excited, unless the impression j)uratjon made upon our organs be repeated or continued during a and certain short space of time. On this principle depends strength of the whole success of the juggler, who contrives to change polsation. the situation of the various objects before us with a ra¬ pidity exceeding the ordinary exercise of sight or touch. A brand whirled swiftly round the head gives all the ap¬ pearance of a circle of fire ; and if one presses very hard an ivory ball between his fingers, he will seem still to feel it for several instants after it has been withdrawn. To excite the sensation of sound, it is requisite that the aerial pulses should have a certain force and duration. Accord¬ ing to some observations, the ear is not affected at all, unless the tremulous impulse communicated to the tym¬ panum lasts during the tenth part of a second. Every pulsation of a more transient kind is lost absolutely and completely to our organ of hearing. On the other hand, the impression of sound is not pro- 118 ACOUSTICS. Acoustics, longed beyond the time of its actual production. If it were otherwise, indeed, all sounds would degenerate into indistinct noises; and articulate discourse, wdiich distin¬ guishes man from the lower animals, and constitutes the charm of social life, would have been utterly impossible. This fact, so obvious, and yet so important, shows indis¬ putably that.the propagation of sonorous pulses through the atmosphere is not, in all its circumstances, analogous to the succession of waves on the surface of water. These undulations continue long afterwards to rise and spread from the centre of their production. The pulsations of the air, no doubt, likewise survive their excitement; but such of them as succeed the first impulsion must not have the force and character of those which are directly shot through the fluid. What is the precise discrimina¬ tion between these different pulses, we are not enabled from mere theory to determine. But such a distinction must undoubtedly exist, otherwise indeed all discourse would continue to fill the ear with a monotonous hum, or an indistinct muttering. It would be difficult to institute conclusive experiments on this subject, yet collateral re¬ searches might be devised which could not fail to guide our inquiry. Concentra- 2. But another defect in the analogy between waves tion in a an(j sonorous pulses is, that the latter, without affecting direction1 t0 sPreac^ e(luaPy> are capable of acquiring a superior force or tendency in some given direction. Certain unconfined sounds, indeed, are diffused uniformly on every side. Thus, the noise of the explosion of a powder-mill is heard, and often dreadfully felt, at a great distance all round the scene of disaster. But the report of a cannon, though audible in every direction, appears invariably loudest in the quarter to which the engine is pointed. On this principle, a seaman, when he seeks to be heard more audibly, or at a greater distance, is accustomed, if no other help occurs, to apply his spread hands on each side of his mouth, and thus check or diminish the waste of sound by its lateral dispersion. For the same reason, the bent and projecting circular piece annexed to the farther end of a speaking-trumpet is of most decided use, in as¬ sisting to give direction to the flight of the aerial pulses. Accumula- 3. The theory of undulatory movements furnishes some tion along elucidation, but no adequate explication, of the augment- barners. e(j effect 0f soun(j in thg direction of a lateral barrier. The extension of such an obstacle might appear to check merely the spread and consequent attenuation of the so¬ norous pulses; but the great accumulation of impulse always occurs, on either side, at the extremity of the ad¬ vancing wave. By what system of interior forces this ef¬ fect is produced, it would be difficult satisfactorily to ex¬ plain. Yet we perceive something analogous in the swell which runs along the margin of a pool, and in the billow which, flowing from the open sea, heaves against the sides of a projecting mole. It is hence that sound is made to sweep with such in¬ tensity over the smooth surface of a long wall or of an ex¬ tended gallery. An elliptical figure, though of manifest advantage, is not really essential to a whispering gallery; for the point of sonorous concentration is found beyond the true catoptrical focus, and much nearer to the wall. A fact of the same kind is well ascertained—that sounds are always heard the most audibly, and at the greatest dis¬ tance, in a level open country, or still better on the smooth surface of a vast lake, or of the ocean itself. The roaring of the cannon in certain naval engagements has been noticed at points so very remote from the scene of action, as might seem, if not perfectly authenticated, to be altogether incredible. On the other hand, again, sound is enfeebled and dissipated sooner in alpine regions. Thus, the traveller, roving at some height above a valley, des- Acou cries, with uncommon clearness, perhaps a huntsman on'^\ the brow of the opposite mountain, and while he watches every flash, yet can he scarcely hear the report of the fowling-piece. On a similar principle, we would explain the operation of the ear-trumpet, which affords such relief to one of the most cheerless maladies that can afflict humanity. The wide mouth of that instrument, it is well known, is turn¬ ed to catch the stream of sound ; the extent of pulsation is gradually contracted as the tide advances; and the same quantity of impulse being probably maintained, the vibratory energy is intensely accumulated at the narrow extremity, where it strikes the cavity of the ear. A trum¬ pet of this form might, in many cases, be found very ad¬ vantageous, not only for remedying the defects of the or¬ gan of hearing, but for assisting the observer to collect feeble and distant sounds. Even an umbrella held close behind the head, with its concavity fronting the sonorous pulses, will, it has been alleged, sensibly heighten their impression. 4. To explain legitimately the reflection of sound, would Reflec require some modifications in the theory of atmospheric modifi undulation. Each obstructing point is certainly not the centre of a new system of pulses ; for, in many cases, this would occasion unutterable confusion. Nor can the ex¬ citement of sound be supposed to dart in straight lines, or to perform the same accurate reflection as the rays of light. In fact, neither smoothness nor exact regularity of surface is required for the production of an echo. A range of buildings, a row of tall trees, a ridge of rocks, or a chain of heights, will, in certain positions, reflect sound with clear and audible effect. It follows, therefore, that the reflection must be formed, not at the immediate sur¬ face of those obstacles, which could occasion only an ir¬ regular dispersion, but at some boundary at a small dis¬ tance, and running parallel to the mean direction of the whole barrier. We may conceive the tide of sound accu¬ mulating where it stops, and investing the opposite sur¬ face like an atmosphere, till a repulsion is exerted, which again rolls it back. What seems to constitute the per¬ fection of an echo is, that the sum of the distances of every point of the reflecting surface from the person who speaks, and from him who listens, should be the same. When this disposition obtains, all the reflected sounds must reach the ear in due succession, without being in¬ termingled or confused. We may observe, that echoes are often confounded with the mere resonance occasioned by vibrations excited among the obstacles themselves. In a large empty room, with its naked floor, and walls, and benches, the voice quickly throws the whole into a tremulous commotion, and seems drowned in the ringing prolonged sound which is produced ; nor does this unpleasant effect cease, until the spectators have occupied the benches, filled the hall, and obstructed by their weight the vibration of the floor. What is called the deadening of sound, consists in merely checking or preventing the disturbance of extraneous tre¬ mor. for this purpose, the floor is covered with carpets, and the walls lined with wainscot or hangings. Such bar¬ riers, we have seen, would not, by their yielding quality, blunt or obstruct the formation of echoes. Their only effect is, to muffle the elastic surfaces which they cover. 1 he performance of the speaking-trumpet has generally gpeak: been referred to the concentrated reflection of sound.trumw Some authors have carried the hypothesis even so far as to investigate, from mathematical principles, the best figure of that instrument. Much labour and great inge¬ nuity have been utterly wasted in this fruitless attempt. , ACOUSTICS. 119 ' Aiiustics. Kircher proposed the tube to be shaped like a truncated parabolic conoid, the mouth-piece occupying the focus; and he concludes that all the rays of sound would, by re¬ flection from such a surface, be sent forward exactly in pa¬ rallel lines. Other philosophers have imagined, from a fanciful analogy to the property of ivory balls, that the figure described by the revolution of the logarithmic curve about its absciss would be the most proper for the speak¬ ing-trumpet. M. Lambert, of the Berlin academy, whose genius and originality were both of the first order, has given a solution still different. But it would be idle to recite the various attempts which have ended in no prac¬ tical result. The true physical explication of the speaking-trumpet was first given, as far as we know, in the course of an in¬ cidental remark by Professor Leslie, in his Experimental Inquiry into the Nature and Propagation of Heat. “ In the case of articulate sounds,” says he, “ the confining of the air does not affect the pitch of voice, but it augments the degree of intonation. The lateral flow being checked, that fugacious medium receives a more condensed and vigorous impulsion. As the breath then escapes more slowly from the mouth, it waits and bears a fuller stroke from the organs of speech. But the speaking-trumpet is only an extension of the same principle. Its performance does certainly not depend upon any supposed repercussion of sound; repeated echoes might divide, but could not augment the quantity of impulse. In reality, however, neither the shape of the instrument, nor the kind of ma¬ terial of which it is made, seems to be of much conse¬ quence. Nor can we admit that the speaking-trumpet possesses any peculiar power of collecting sound in one : direction; for it is distinctly audible on all sides, and is perhaps not much louder in front,'comparatively, than the simple unassisted voice. The tube, by its length and narrowness, detains the efflux of air, and has the same effect as if it diminished the volubility of that fluid, or in¬ creased its density. The organs of articulation strike with concentrated force; and the pulses, so vigorously thus excited, are, from the reflected form of the aperture, finally enabled to escape, and to spread themselves along the atmosphere. To speak through a trumpet costs a very sensible effort, and soon fatigues and exhausts a per¬ son. This observation singularly confirms the justness of the theory which I have now brought forward.” Nearly about the same time, this theory was confirmed Ha:;n. by some ingenious experiments made by M. Hassenfratz, **tl at Paris. His method of estimating the power of a speaking-trumpet consisted in fixing a small watch in the mouth-piece, and observing at what distance the beats ceased to be distinctly audible. He found that the effects were precisely the same with a trumpet of tinned iron, whether used in its naked form, or after it was tightly bound with linen to prevent any vibration of the metal. Nor could there be the smallest reflection of sound from the internal surface of the tube, for the beating of the watch was heard exactly at the same distance after the whole of the inside had been lined with woollen cloth. These simple experiments prove decisively that the per¬ formance of the speaking-trumpet depends principally on the intenser pulsation which is excited in the column of confined air. In the same way, sound is prodigiously aug- mented in a long narrow passage. If a musket be fired within the gallery of a mine, thfe explosion heard in a remote corner will have the loudness and character of thunder. . The progressive motion of sound furnishes the explica- P ry* tion of various remarkable facts and striking phenomena. Thus, to a person standing at some distance, and directly Acoustics, in front of a long file of musketry, the general discharge will appear as a single collected sound, the numerous re¬ ports all reaching his ear nearly at the same instant. But one stationed at the end of the line will hear only a pro¬ longed rolling noise, not unlike a running fire ; because the distinct sounds, from the different distances which they have to travel, will arrive in a continued succession. Hence, likewise, the tremendous rumbling noise of dis-Noise of tant thunder, which is not produced, as many have sup-thunder, posed, by the repetition of echoes. In certain situations, indeed, and particularly in hilly tracts, echoes may no doubt contribute to augment the general effect; but their ordinary influence seems to be really insignificant, since it should cause the same modification of sound in the explosion of a cannon, which is essentially different, however, from the muttering and crash of thunder. This lengthened and varied noise must yet be the production of a moment. The rapidity of lightning surpasses concep¬ tion, and the prolongation of the sound which follows it is owing to the various distances of the chain of points which emit the sonorous impressions. The electrical in¬ fluence darts with immeasurable swiftness from cloud to cloud, till perhaps it strikes at last into the ground. But from every point of this tortuous path distinct pulses of sound are transmitted, which consequently reach the ear at very different intervals. Sometimes they arrive inter¬ mingled, and give the sensation of a violent crash; at other times they seem suspended, and form a sort of pause. It would not be very difficult in any case to imagine the zig-zag track which the lightning must pursue in or¬ der to produce a given protracted rumbling noise. The duration of each peal of thunder will evidently be short¬ ened if it chance to shoot athwart, but must continue the longest when it runs in the line of the spectator. As the distance of thunder is estimated by allowing some¬ what more than a mile for every five seconds that elapse between the flash and the beginning of the report, so the space traversed by the lightning, if its general direction were known, might be computed by the same rule, from the endurance of the sound. We will not enter at present on that branch of acoustics Musical which treats of the doctrine of harmony ; but a few scat- note, tered remarks may trace the general outline of the sub¬ ject. A musical note, far from being only a repetition of the same simple sound, should be considered as the con¬ junction of subordinate sounds reiterated at proportional intervals. The sweetness of this compound effect or tone appears to depend on the frequent recurrence of interior unison. The secondary sounds which naturally and in¬ variably accompany the fundamental note are repeated only two, three, or four times faster; nor does the science of music admit of any proportions but what arise from the limited combinations of those very simple num¬ bers. Harmony, again, is created by an artificial union of different notes, analogous to the natural composition of tone. All tones are produced by the regular vibrations either Vibrating of solid substances or of confined air itself. Strings instru- of gut or of metal are most generally used; but small ments. plates or pillars of wood, of glass, or even of stone, will answer the same purpose, forming the singular instru¬ ment called staccata or harmonica. In these cases, the quality of the vibrations depends on the joint influence of a variety of circumstances; not only on the length of the fibres, but on their thickness, their elasticity, their density, and the degree of tension to which they are sub¬ jected. The motion of a musical stretched chord v/as first investigated by the very ingenious Dr Brook Taylor, 120 ACOUSTICS. Acoustics, though his solution has been since proved to be incom- plete. At the same time, in fact, that the whole chord oscillates, its simpler portions, the half, the third, and the fourth of its length, actually perform a set of intermediate vibrations. Wind-in- Wind-instruments produce their effect by the vibra- struments. tions of a column of air confined at one end, and either open or shut at the other. These vibrations are deter¬ mined merely by the length of the sounding column. Yet interior and subordinate vibrations are found to co-exist with the fundamental one. The whole column sponta¬ neously divides itself into portions equal to the half, the third, or the fourth of its longitudinal extent. We shall more easily conceive these longitudinal vibrations, by ob¬ serving the contractions and expansions of a long and very elastic string, to the end of which a ball is attached. A spiral spring shows still better the repeated stretching and recoil, if struck suddenly at the one end, it will ex¬ hibit not only a total vibration, but likewise partial ones, winding vermicularly along the chain of elastic rings. But when the air is struck with uncommon force, the subordinate vibrations become predominant, and yield the clearest and loudest tones. This we perceive in the dy¬ ing sounds of a bell, which rise by one or two octaves, and expire in the shrillest note. On such a very narrow foun¬ dation—on the variable force with which it is blown— rests the whole performance of the bugle-horn, whose compass is extremely small, consisting only of the simplest notes. In other wind-instruments, the several notes are caused by the different lengths of the tube, or by the va¬ rious positions of the holes made in its side. Tones pro- The longitudinal vibrations of a column of air, contain- duced by ed within a tube open at both ends, are powerfully excit- the burn- e(J? an(J Very loud and clear tones produced, by the inflam • \ng -r" mation of a streamlet of hydrogen gas. This curious ex- t rogengas. perjment wag ma(je grst jn Germany, an{i appears indeed to have been scarcely known, or at least noticed in other countries. Yet it is most easily performed, and will be considered as amusing, if not instructive. A phial, having a long narrow glass pipe fitted to its neck, being partly filled with dilute sulphuric acid, a few bits of zinc are dropt into the liquid. As the decomposition of the water embodied with the acid now proceeds, the hydrogen gas thus generated flows regularly from the aperture, and is capable of catching fire, and of burning for some consid¬ erable time, with a small yet steady round flame. This very simple arrangement, frequently styled the philosophic lamp, is in reality of the same nature with the combina¬ tion, on a large scale, of the gas lights. A glass tube be¬ ing passed over the exit-pipe, the burning speck at its point instantly shoots into an elongated flame, and creates a continued sharp and brilliant musical sound. This effect is not owing to any vibrations of the tube itself, for it is nowise altered by tying a handkerchief tightly about the glass, or even by substituting a cylinder of paper. The tremor excited in the column of air is therefore the sole cause of the incessant tone, which only varies by a change in the place of the flame, or a partial obstruction applied at the end of the tube. But still it is not easy to con¬ ceive how the mere burning of a jet of hydrogen gas ^within the cavity should produce such powerful vibra¬ tions. The exciting force must necessarily act by starts, and not uniformly. The length of the flame might seem to prove, that the hydrogen gas is not consumed or con¬ verted into aqueous vapour as fast as it issues from the aperture. A jet of it catches instantaneous fire, but is immediately followed by another, the succession of in¬ flamed portions being so rapid as entirely to escape the keenness of sight. The column of air contained within the tube would thus be agitated by a series of incessant Acou strokes or sudden expansions. The singular fact now described had occurred inciden¬ tally to the writer of this article in the course of his ear¬ liest experiments; and he has often thought since, that, on the same principle, an organ might be constructed, which would have a very curious and pleasing effect. A vertical motion of the glass tubes, and the partial shutting or opening of their upper ends, would occasion a consider¬ able variety of notes. By passing the hydrogen gas over different metals, the flame would be made to assume va¬ rious colours. The apparatus might work by a spontane¬ ous mechanism; and while the eye was gratified by the display of rich and vivid tints, the ear would be charmed with strains of new and melodious symphony. (b.) Part III. We shall here add some further explanations in regard pistjr to the nature of different sounds, and particularly oftionb musical sounds. tween Nothing appears more surprising than that variety ofsical! sounds which different bodies emit when excited eitherother by percussion or by any other method. If we strike,80™ for example, upon a log of wood, or a table, or a book, we obtain nothing but a harsh sort of noise, which ceases almost the moment it is emitted. Whatever shape we form the wood into, it makes hardly any dif¬ ference. The same thing takes place with other bodies, such as metal, or glass, or earthen ware, &c. when these are in large masses; but how different is the case if we form them into rods or slips, into thin plates, or, still better, into cylindrical or hemispherical vessels, as cups, tumblers, bells, cymbals, &c. These, when struck, inva¬ riably emit a sound much more prolonged, and in general highly musical or grateful to the ear. What, then, is the cause of this remarkable distinction ? All that we can observe generally in regard to these sonorous bodies when sounding is, that the whole body is agitated by an inter¬ nal tremor, which continues so long as the sound can be heard. But if we examine them in their simplest forms, some very remarkable circumstances are brought to light. Take, for example, a slip of metal or glass, fix it firmly at one extremity, and then strike the other; the body, as in other cases, emits a prolonged and musical note, and becomes agitated with the usual sonorous tremor. This is particularly well observed in a common tuning fork. But the nature of this agitation is of a very simple kind. The slip merely oscillates backwards and forwards with great rapidity on the extremity by which it is fixed. Each of these oscillations, as the slip strikes the surrounding air, must produce a distinct sound; but these impressions following each other in very rapid succession, the ear can distinguish nothing but a single continued and prolonged note. The same thing takes place if we fix the slip at both ends, providetl it be long enough and thin enough to oscil¬ late in the middle; and this is the case with all kinds of distended wires or strings. These are fixed at the two ends, and when they are struck, as with the hammer of the key of the piano-forte, or drawn aside by the hand and then abandoned, they continue to vibrate for a long time, and to emit tones varying in gravity or acuteness, but all highly musical. One remarkable circumstance regarding the vibrations of these slips or chords is, that they are all performed in the very same time, however minute or how¬ ever extended. They vary in different slips or chords, ac¬ cording to their length, tension, and other circumstances; but in the same slip or chord they are all alike. When any chord or slip is drawn out of the straight line and then abandoned, the oscillations are wide at first, but 1 ACOUSTICS. 121 ustics. continually diminish in extent till they cease altogether, as at Plate I. Fig. 1. Now the smallest of these vibra¬ tions takes just as long time in its performance as the largest; and the latter, again, however wide, is performed just as quickly as the former. The reason is, that the force of elasticity, which produces the vibrations, increases as the chord is drawn farther from the straight line, and thus accelerates the wide vibrations in proportion to their extent, as can easily be demonstrated. The consequence is, that the successive impressions of sound which consti¬ tute the continued and prolonged note, all follow each other at the same interval; and the regularity with which these impressions successively fall on the ear appears to be one essential ingredient in that melody or agreeable effect which the sound produces. This is proved by a very simple experiment. If we sound one of the strings of a violin or violoncello, it emits for a long time the mu¬ sical note which belongs to it; but if, while it is sounding, we move the finger quickly along it from the bottom upwards, so as to shorten continually the length of the string, to accelerate thereby the vibrations, and thus alter the regularity of their succession, the sound continues, but all sort of melody is gone. Some philosophers, and in particular Dr Robison, have thought that this regular succession of sonorous impressions is the only source of melody; but this is far from being the case, else how could we account for those diversities in the sweetness of different tones, produced by different instruments or from different sources ? What can be more regular in succession than the impressions of sound from a distant water-fall ? And accordingly the effect is soft and agreeable in a high degree, yet how inferior in melody to the tone of a fine bell, or of an organ, or the notes of a distant bugle. Another remarkable circumstance regarding the vibrations of these slips or chords is, that the sound is not emitted from the string itself so much as from the mass with which it com¬ municates. If, for example, we strike a tuning fork gently, so as to make it vibrate, it emits a sound so feeble that it cannot be heard until we bring it close up to the ear; but if, when it is vibrating, we press the extremity on a table, or a book, or any similar substance, the sound becomes perfectly audible. In the same manner a distended wire, if quite insulated, hardly emits an audible tone ; but set it on a board, or, which is still better, on a hollow box, and then the tones are loud, deep, and highly musical. Many authors who have treated this subject ascribe the sound to the wire or chord striking the air at every vibration. This, however, is but an imperfect view of what really takes place. The tones arising from this source are in general perfectly inaudible, and the use of the wire is rather to excite the vibrations in the mass with which it is con¬ nected. This is the true sonorous body; and in this man¬ ner even wood, which appears when struck the most tune¬ less of all substances, is yet made to emit tones of the most exquisite sweetness; as appears in the violin and violoncello, harp, and indeed in all stringed instruments. The wood appears incapable of having a continued series of vibrations excited in it by percussion; but the strings produce this effect in a very remarkable manner, and which has hardly received that attention from writers on Acoustics which it deserves. They put the whole mass of the wood into a tremor, they excite its vibrations, and they deter¬ mine and govern their frequency and the regularity of their succession. These vibrations over the whole surface of the wood communicate an infinite multitude of similar vibrations in the air, all which reaching the ear at the same instant, produce those powerful and audible tones which we observe. Let us now consider the nature of those remarkable VOL. II distinctions of musical sounds into grave and acute, on Acoustics, the combination of which depends the whole charm of'^-v^-' music. Every one knows, that in stringed instruments Grave and this depends entirely on the length and tension of theacute string, as is well observed in the violin. By shorteningS0UIul3 the strings with the fingers, we obtain notes always more and more acute; and by tightening the strings with the pins at their extremities, we produce the same effect. In different strings, also, another circumstance has a sensible effect, namely, the thickness or mass of the string: the greater this is, the sound is the more grave, and the less the more acute. All these effects are very clearly ob¬ served, and proved with mathematical accuracy, by means of an instrument termed the monochord or sonometer; which is an apparatus contrived for stretching different strings and causing them to sound by vibration, with props or bridges to vary their lengths, and weights sus¬ pended to vary and measure the different tensions, the vi¬ brations of the strings being communicated to a hollow box of thin elastic wood, to augment the sound. Fig. 2. represents the instrument in an upright form, which is best adapted for experiment with tension, because the weight can be applied directly under the string without friction. Fig. 3. is a horizontal form: the weight here is applied over a pulley, and therefore the tension cannot be so very ac¬ curately measured. It answers, however, better for some other kinds of experiments, in regard to the length of the strings and the subordinate vibrations. Whichever of these forms of the instrument be used, we obtain invari¬ ably the same results. The more weight we apply to stretch any of the chords, the more acute does the sound become. If we lengthen the strings again in any degree, the more grave does the sound become; and the same takes place if we substitute a heavy for a light string. It is very remarkable, however, that if we examine these effects carefully, and apply the aid of mathematical investigation, they all resolve into one general law. Adding to the weight and tension on the strings, shortening their length and diminishing their weight, have all the same common effect; namely, to quicken their vibrations. It is on the single circumstance, therefore, of the quickness or slow¬ ness of the vibrations of the strings, in whatever way it is produced, that the acuteness or gravity of the tones de¬ pends. This, then, is the great law on which all the gradations of musical notes depend: quicken the vibra¬ tions of the chord by any means, and we are sure to sharpen the tone in the very same proportion: make the vibrations slower in any way, and in the same proportion does the tone become more grave. The above circumstances, how¬ ever, do not all alter the rate of vibration in the same de¬ gree. If we shorten or lengthen the string, the vibrations are quickened or slackened, and consequently the tones made more acute or grave in the very same proportion; that is, a string half the length of another just makes double the number of vibrations in the same time, and one one-third of the length three times ; one double the length, again, makes half the number of vibrations, and one triple the length one-third of the number. The effect of the tension, again, and the weight of the strings, follows a different law. If we load one string with double the weight of another, it does not double the number of vibra¬ tions : it requires four times the weight to do this, and nine times the weight to triple the number; the quickness being in all cases in proportion to the square root of the weight. The effect of the weight of the string follows a similar law; one string requiring four times the mass of another to make its vibrations in half the time, and nine times this to make them in one-third of the time. So that if we denote the length of the string by L, the weight Q ACOUSTICS. Acoustics, of a lineal inch by W, and the weight or force of tension by T, then the number of vibrations, N, in a given time will be /T in proportion to On this law depends the construction of all kinds of stringed instruments, and the adjustment of the length, magnitude, and tension of the strings, to produce the tones that we wish in the instrument, without over¬ straining the materials, or making them any way liable to go out of tune. Accurate experiments, however, are want¬ ing to apply with success the above formula to actual practice. On the above principle, also, of the velocity of the vibrations regulating the tone of every sound, de¬ pends entirely the system of our musical scale, as well as all those combinations of sound which constitute concord or harmony in music. Every one knows, that if with any sound we strike its octave at the same time, the two coalesce so completely together as to form al¬ most a single continued note, which in music forms the most perfect concord. Now the octave above is emitted from that string whose vibrations are exactly double in number to the original note. The vibrations of the latter, therefore, must coincide completely with the former at every other vibration. The impression of both thesereaches the ear at the very same instant, and thus the two sounds are blended into one. The intermediate sound of the octave which intervenes between these is hardly perceiv¬ ed, owing to the rapidity of their succession; and as it also recurs at regular intervals, it does not interrupt the harmony, but rather contributes to give fulness and rich¬ ness to the combined tone. The same thing takes place, though in a less degree, with the double, the triple, and other octaves, and with all the different sounds which form concords together; and the more frequently the two sounds unite, the more perfect in every case is the con¬ cord. When they do not unite but at sensible intervals, there is then produced at each of these a distinct rise in the sound, which becomes suddenly louder from the union of the two, and then diminishes as they begin to separate, producing a succession of swells, or beats, as they are termed in music. The intervals between these beats are filled up by the vibrations of the two sounds occurring, first one and then the other; and as they form on the whole a very irregular succession of impressions, they pro¬ duce a jarring effect, which grates on the ear. These combined sounds are hence termed discords. All this will be readily understood by an example or two, and a figure. Take first the fundamental tone and its octave; let the vibrations of each which produce the continued sound be represented by dots, as at Fig. 4 ; and when the two sounds concur, let this be denoted by dots larger in size: then the succession of impressions will be as at Fig. 5, where we have a regular succession of beats, re¬ curring in such rapid succession that the ear can only distinguish a single sound. The octave also intervenes, but quite regularly, and also in such rapid succession, that it seems rather to heighten than to mar the general harmony. In the same manner, Fig. 6. represents the union of the fundamental sound and its double octave; which is the same system, only the beats are at wider in¬ tervals, and the intermediate octaves double in number. Take now two sounds, the number of whose vibrations are to each other as 2 to 3 ; that is, suppose one of them performs its vibrations in- two very small parts of a second, and the other in three. If we take the annexed scale to represent the parts of a second, we easily form the series of sounds and of beats at Fig. 7. We have still, it will be seen, a regular succession of beats, but the in¬ termediate single sounds do not recur at regular intervals. v We have first an interval of two parts of a second; then we Acoil have three sounds succeeding each other during the other three parts; and then a:a interval of two parts between that and the beat. There is obviously, therefore, a tendency to discord; but the whole series occurs in such rapid suc¬ cession that the effect on the ear is quite harmonious. Take now the proportion of 5 to 7. Here, as at Fig. 8, we have a regular succession of beats, but we have no fewer than ten intermediate single sounds, and these suc¬ ceeding each other in a very irregular manner. We have all the elements of discord, therefore; and accordingly the union of these two sounds would be sure to grate on the ear, unless they were of so high a pitch that the beats should become inaudible. These would then produce, as before, a continued sound; and the effect of the interme¬ diate ones would be in some degree, but not altogether, lost: we might have a concord, but not a very perfect one. It hence appears obvious why the union of some notes, which on a grave key are discordant, become har¬ monious by raising sufficiently the pitch. In the same manner, in every other case the greater the intervals be¬ tween the successive conjunctions of the sounds, and the more irregular the succession of the intermediate impres¬ sion, the greater will be the discord. Such are the effects of combined sounds; but it is ex¬ tremely remarkable that every single sound, besides its fundamental note, yields also spontaneously various others of the most perfect concord with it, but all higher, and each rising successively in pitch, so that they have hence received the name of Acute Harmonics. This curious and important fact, first noticed by Galileo, to whom also we are indebted for the theory of musical strings, has since excited much attention among succeeding philoso¬ phers, as well as among those skilled in the practice of music. In stringed instruments, it is best observed in the low notes of the piano-forte or violoncello. These wrere formerly thought to emit one simple uniform tone. An attentive ear, however, as is now universally allowed by musicians, can actually discover three others besides the original, viz. the octave above, the twelfth, and the double octave. This was first distinctly proved by Ra¬ meau ; and the experiment is easily tried by striking one of the low keys, and withdrawing the finger briskly: j then, after the fundamental note has ceased, the three shriller ones will be heard. The octave being in some measure blended with the original note, is not so easily perceived, except by an ear habituated to the minutest discrimination of sound. But with ordinary attention the twelfth and the double octave are heard distinctly. Nothing in the whole science of Acoustics has given rise to so much speculation and varied discussion as this singu¬ lar property of musical strings. It would appear at first sight to overturn the whole doctrine we have been laying down regarding the effect of the rapidity of the vibrations in regulating the tone ; for here we have the same string yielding at once a diversity of notes, varying in a wide gradation from grave to acute. Can it be possible that the string, besides one principal series of vibrations from end to end, may at the same time execute vibrations among its parts, throwing itself, as in Fig.Q, into two, three, or four subdivisions; and the whole string, as it oscillates between its extremities, serving as a movable axis on which such partial vibrations may be at the same time performed ? This appeared at first so extraordinary and wild a conjecture, that it was long ere it could meet with any serious attention among philosophers, far less be ad¬ mitted as an accurate view of what really takes place. It was rather ascribed to something unconnected with thp string; some referring the production of these harmonic ACOUSTICS. 123 j Adistics. notes to the structure of the ear, and the mode in which receives the impression of the fundamental note; others, as the celebrated Lagrange, (to whom, along with our countryman Taylor, and Bernoulli, Euler, and D’Alembert, we owe the whole theory of the curves assum¬ ed by the vibration of musical strings,) supposed that they arose from sympathetic vibrations excited in the dif¬ ferent bodies adjacent to the string, but without attempt¬ ing to give any reason why these affections should always excite notes more acute than the fundamental. The pos¬ sibility of these partial vibrations, however, was clearly proved by Daniel Bernoulli; and, however curious it may seem, the fact has now been established by many conclu¬ sive experiments and observations. That strings are cap¬ able of vibrating in this way, we may be convinced, from the following considerations. If we take any string, and withdraw it from the straight line by applying the finger, not to the centre, but nearer to one of the ends, so as to bring it into the position ABC, Fig. 10, then it will on the other side assume the position ADC, in every way the reverse of the first, as is easily proved by experiment. In general, the vibrations are so quick that they cannot be perceived by the eye ; but if the finger be held op¬ posite to B, or in any other part between A and C, it will be found that the vibration is nowhere so great as at D. In the same manner, if we apply both fingers in opposite directions, and at equal distances from the extremities, so as to draw the string into the position A B D C, the cen¬ tre E remaining unchanged, thdn, on the other side, it will assume the position A 6 E C; and as the central point E continues all the time immovable, it is evident that the whole string will continue vibrating partially, in I the very same manner as if it had been composed of two strings, each half the length, and fixed at E. This point E is hence generally termed a node, or nodal point. In the same way, by applying the moving forces at other different points, the string may be made to perform three, four, or any greater number of partial vibrations, in relation to so many intermediate nodal points, Fig. 12; and it is not difficult to conceive, therefore, how, by the application of certain forces, the whole string may be performing its oscillations from end to end, while at the same time it may be agitated internally by two, three, or more partial vibrations; and this is proved by actual experiment. If we take a piece of common twine about fifteen or twenty feet long, and stretch it between two fixed points rather loose¬ ly ;—if we then cause it to vibrate by the middle, it merely makes the ordinary vibrations; but if we apply our force to withdraw it from the straight line near one of the ex¬ tremities, we can then see distinctly, besides its principal vibrations, a series of subordinate ones going on throughout its whole length. It is remarkable also that strings of this kind are extremely susceptible of these subordinate vibra¬ tions. When the string is vibrating regularly between its extremities, the slightest deranging circumstance is sufficient to excite and to superinduce the partial actions; as appears very distinctly in an experiment contrived by Mr Hawkins of London, by stretching between two bridges a long and spirally coiled brass wire, the spirals being about the diameter of a quill, and extended considerably more than those of a cork-screw. The tension was such as hardly to emit any sound, but to leave the vibrations when touched quite visible to the eye. If, when the whole string I is vibrating, we oppose a slight obstacle, say at the middle, the string then instantly divides itself into two, and along with its principal vibration performs two others between the centre and each extremity. If the obstacle—and even a puff of wind from the mouth is sufficient—be placed at the distance of one-fourth the length of the string from either extremity, then it divides itself into four, and along Acoustics, with its principal vibration performs four others ; and so on, according to whatever aliquot part of the string the obstacle be presented ; the latter always subdividing itself into the same number of parts, and performing a series of subordinate vibrations between each, which can often be observed and heard for several minutes accompanying the principal one. The same effects are beautifully ob¬ served, as was first shown by Professor Robison, by means of a monochord sounded by an ivory wheel. When the string was vibrating simply, if its middle point was then touched slightly with a quill, this point instantly stopped, but the string continued to vibrate in two parts, sounding the octave; and the same thing happened if it was touched at one-third,—it then divided itself into three parts, with two nodal points, and sounded the twelfth ; and any thing soft, such as a lock of cotton, put in the way of the wide vibrations of the string, was sufficient to produce the effect. From these facts and observations, therefore, no doubt can remain that the acute harmonics accompanying the fundamental note arise entirely from these partial vibra¬ tions, of which every string appears to be so suscep¬ tible. But one important question still remains, and has never yet received any satisfactory solution; namely, what are the circumstances which determine these par¬ tial vibrations so generally in every string ? Very slight ob¬ stacles are no doubt sufficient, but still there must be some particular causes to determine every string to divide itself so regularly into two, three, four, or more parts; exe¬ cuting in such regular succession the vibration peculiar to each. Inequalities in the densities or thicknesses of the different parts of the strings have been suggested as a probable reason; but this appears quite inadequate to pro¬ duce effects so very constant in their operation, and v/hich besides occur, let the string or wire be ever so uniform in its texture. This subject requires further examination, and the trial of several experiments. The only probable circumstance to which we can ascribe these effects consists in the re-action of the supports to which the extremities of the strings are attached. It is well known, that when two strings in the same instrument are tuned to the same note, if one of them be struck, the other begins to vibrate, and to sound at the same time. Strings differing by an octave have the same effect; and even those differing more in tone, yet appear to act and to re-act on each other. These effects have usually been ascribed to the action of the air, communicating the vibrations from one string to another. This, however, is not the case, as is proved by a simple experiment. If we stretch two similar strings on two different boards, and tune them to the same note; then if we detach the one wholly from the other, the vibrations of the one do not in the least affect those of the other, let them be even brought quite close together. But the moment we place the boards in contact with each other, though the strings themselves be thereby farther separated than before, yet the one vibrates uniformly in sympathy with the other ; and the moment the boards are again de¬ tached, the effect ceases. It is clear, therefore, that the vibrations of the one string are communicated to those of the other, not through the medium of the air, but through that of the wood; and this can only take place by means of the vibrations of the one string communicating through the supports to the wood. This agitates the supports of the other string, and these giving at first a very slight vibrating motion to the extremities, this gradually increases as it is continued, until the whole string is made to vibrate with the other. Instead of the effect, therefore, proceed¬ ing from the middle of the string to either extremity, as \ 124 A C Q Acoustics would be the case with aerial pulses, it is just the reverse. II When once the motion is begun, the aerial undulations Acqs. may certainly aid and augment the effect; but this, with¬ out doubt, originates at the extremities of the strings, and from these is communicated to the centre. That strings in unison with each other should vibrate in this manner more read'ly than any other, is quite easily accounted for; because in that case the vibrations of the one, however they may be produced, are quite isochronous with those of the other: they are more readily excited, therefore, because when they are once begun, however minute they may be at first, they yet harmonize exactly with the other, and every succeeding impulse from it justarrives in the proper time to augment the effect of the preceding, until the two motions become exactly alike. Were the string not isochronous, the succeeding impulses might tend sometimes to augment and sometimes to diminish the effect of the preceding ones; so that no sensible vibration would take place, as really hap¬ pens with all discordant strings. With octaves, however, and other concords, the vibrations are still produced, because the vibrations of the fundamental note always concur with those at certain intervals, and at others do not oppose them. All these effects are very similar to what occurs in the motion of pendulums ; a very slight impulse is suffi¬ cient to put a large pendulum into very wide vibrations, if it be often repeated, and always at the proper time to aug¬ ment and not oppose the motion already communicated. Here it is that pendulums swinging in the same frame affect wonderfully the vibrations of each other, exactly like musical strings in the same instrument. If when two isochronous pendulums are at rest one of them be set in motion, in a short time the other commences to vibrate, in a very slight degree at first, but always increasing and in¬ creasing, until at last its oscillations become quite as wide as the other. This effect arises entirely from the vibrations of the one pendulum communicating through the wood very slight impulses to the axis or centre on which the other moves. This sets it in motion, and the impulses being constantly repeated and properly timed, excite at last vibrations as wide as the original. In a similar man¬ ner it is that one string causes another in the same instru¬ ment to vibrate, by means of the supports on which it is stretched; and if this be the case so remarkably in dif¬ ferent strings, may not the vibrations of any single string re-act on itself through its own supports, and thus excite all those secondary vibrations which produce the acute har¬ monics ? The string being first struck in the centre, the fundamental note must first of all be emitted. But the vibration of this agitating the supports at each extre¬ mity, these must necessarily re-act upon the string it¬ self, must modify the original central impulse, and ex¬ cite all those subordinate vibrations which are observed. That this is the true cause of these partial actions, and con¬ sequently of all those varied tones which they excite, appears extremely probable. But experiments, as we observed, are wanting to demonstrate these effects satisfactorily. Such, then, are the singular phenomena of the acute harmonics, and of the subordinate vibrations of strings from whence they arise. Whatever be the cause of these, no doubt whatever can remain of the fact itself; and it is to this circumstance that we must perhaps ascribe much of that agreeable effect, so pleasing to the ear, which A C Q we experience in the tones of our musical instruments. Aco Regularity of succession may determine a certain pitch in the sound; but it is from the harmonic tones ming- Acjl ling together, and blending with the gravity of the ori-yj^ ginal note, that appears to arise all that sweetness and rich melody which so peculiarly belongs to them. Hence also we can now understand the reason of the musical ef¬ fect arising from the sound of thin plates, cups, or bells : in all these, when they are examined minutely, we observe numerous vibrations among the parts ; the substance of the plate dividing itself into various subdivisions, separated by nodal lines, between which all the parts are thrown into vibration. Hence arise a variety of harmonious notes; and these mingling together, produce that highly musical ef¬ fect which we observe. It is to Professor Chladni that we owe a 'variety of curious facts regarding these vibra¬ tions of plates ; which he observed by strewing them with fine sand: the nodal points and lines were then shown by the sand throwing itself from all the vibrating parts, and accumulating in little heaps along the lines which divide the vibrating surface, and where, therefore, there was no agitation at all. Squares of plate glass are well adapted for showing these effects. If we hold these by the centre in a sort of small wooden vice, as at Fig. 13, and then cause them to sound by drawing a bow along any of the edges, which are smoothed for the purpose with emery, the gravest tone is produced by applying the bow to one of the angles ; and then the sand assumes the figure represented in Fig. 14. The tone next to this in graveness is produced by applying the bow to the mid¬ dle of one of the sides; and then the sand assumes the figure represented in Fig. 15. By varying the points of ap¬ plication in this manner, and the figure of the plates, we obtain many other figures and curves for the nodal lines; such as Fig. 16, 17, 18, 19, &c. These effects are ex¬ tremely curious and interesting: they are also very beau¬ tifully exhibited by plates of paper or other flexible mem¬ branes, stretched on frames like those of a drum or tam¬ bourine. But we must refer for further details on this subject to the Traite d'Acoustique of Chladni. Besides the lateral vibrations above described, of strings, membranes, and plates, all these bodies are cap¬ able of vibrating longitudinally, and of emitting sounds which are in general much more acute than the others, and are regulated in their pitch by the length of the rods or strings. In this manner even the air itself, confined in a tube or pipe, is made to vibrate regularly, and to emit mu¬ sical tones; and from this source arises another extensive and very important class of sounds, namely, those which are produced by the various kinds of wind-instruments, and of which also the tones of the human voice and of that of different animals present interesting examples. One is apt to imagine that the sound of a pipe or flute is emitted from the wood or other material of which it is composed ; it really, however, arises from the cylinder of inclosed air, which is thrown into vibration by the current 1 of air striking against the reed of the pipe, or against the sides of the hole in the plate. For a particular account of this class of sounds, see Wind-Instruments, Organ, Trumpet, &c. ; and for a more particular accodnt of the scale, and of musical harmony, see Harmonics, Music, Temperament.

ACQS, a town at the foot of the Pyrenean moun- ACQUAPENDENTE, a pretty large town of Italy, in tains, in the department of Arriege and late province of the territory of the Church and patrimony of St Peter, toix, in prance. It takes its name from the hot waters with a bishop’s see. It is seated on a mountain near the m these parts. river Paglia, 10 miles west of Orvieto, and 57 north by A C R A ria west of Rome. It takes its name from a fall of water 11| near it, and is now almost desolate, iragas. ACQUARIA, a small town of Italy, in Frigana, a ^ v-0(jjstrict 0f Modena, which is remarkable for its medi¬ cinal waters. It is 18 miles south-west of the city of Modena. ■ T • a j * ACQUEST, or Acquist, in Law, signifies goods got by purchase or donation. ACQUI, one of the provinces into which the conti¬ nental dominions of the king of Sardinia are divided. It is bounded on the north-east by Alessandria, on the south¬ east and south by Genoa, on the south-west by Mondovi, on the west by Alba, and on the north-west by Asti. The extent is 534 square miles, or 341*760 acres. In the north the mountains decline to a fine undulating plain, watered by the rivers Bormido, Orbo, Erro, and Belbo, which in the adjoining province fall into the Tanaro, and then join the Po. The land is productive, and yields wheat, garden vegetables, wine, fruit, chesnuts, and much silk. Some cattle are bred and fattened; but the chief call for labour is in winding and throwing the silk. There are a few mines of iron and of some other minerals, but all inconsiderable. This province, which formerly was SUpper Montserrat, contains two cities, 81 towns and vil¬ lages, and nine hamlets, with a population amounting to 91,535 persons. Acqui, a town of Italy, in the duchy of Montferrat, with a bishop’s see and commodious baths. It was taken !by the Spaniards in 1745, and retaken by the Piedmontese in 1746; but after this it was taken again and dismantled by the French, who afterwards forsook it. It is seated on the river Bormia, 25 miles north-west of Genoa, and 30 south of Casal. Long. 8. 19. E. Lat. 44. 4. N. ACQUISITION, in general, denotes the obtaining or procuring something. Among lawyers it is used for the right or title to an estate got by purchase or donation. ACQUITTANCE, a release or discharge in writing for a sum of money, witnessing that the party has paid the said sum. ACRA, a considerable country near the eastern extre¬ mity of the Gold Coast of Africa. It is fertile, healthy, and the inhabitants are of a more polished and civilized character than the majority of those found upon that coast. While the slave-trade was carried on with acti¬ vity, there was a great resort of the European nations to Acra, and the factories established by them: Fort James I by the English, Crevecceur by the Dutch, and Christians- borg by the Danes, were the centre of an extensive trade. Acra has now greatly declined; and it may be considered, along with the rest of the coast, as dependent upon Ashantee. Adams considers this country as the boundary of the gold trade on the one side, and the ivory trade on the other; and sharing to a certain degree in I both, though not to the same extent with some other dis¬ tricts. Acra, in Ancient Geography, one of the hills of Jeru¬ salem, on which stood the lower town, which was the old Jerusalem; to which was afterwards added Zion, or the city of David. It was probably called Acra, from the fortress which Antiochus built there in order to annoy the temple, and which Simon Maccabeus took and razed to the ground. Acra Japygia, in Ancient Geography, called Salentia by Ptolemy; now Capo di Lexica : a promontory in the kingdom of Naples, to the south-east of Otranto. ACRAGAS, or Agragas, in Ancient Geography, so called by the Greeks, and sometimes by the Romans, but more generally Agrigentum by the latter; a town on the south coast of Sicily. See Agrigentum. A C R 125 ACRAMAR. See Van. Acramar ACRASIA, among physicians, implies the predomi- II nancy of one quality above another, either with regard ^ to artificial mixtures, or the humours of the human body. The word is Greek, and compounded of a pri¬ vative, and xigavvvgi, to mix; q. d. not mixed in a just proportion. ACRE, or Acra, a town and seaport of Palestine, in the pachalic of Acre, and formerly a splendid city of antiquity, called Ptolemais, from Ptolemy, king of Egypt. It was named Acra from its fortifications; and by the knights of St John of Jerusalem it was called St John d’Acre. No town has experienced greater changes from poUtical revolutions and the calamities of war. It has been successively possessed by Alexander’s successors, who ruled in Egypt, by the Romans, the Sa¬ racens, the Christian crusaders, and finally by the Turks. According to some travellers, this city was the Accho of the Scriptures, one of the strongholds of which the Is¬ raelites could not dispossess the Canaanites; and in con¬ firmation of this supposition, Mr Buckingham, who visited Acre in 1816, found in the ditches which they were then digging around the wall, fragments of houses which bore marks of the highest antiquity; consisting of that highly sun-burnt brick, with a mixture of cement and sand, which was only used in buildings constructed in the re¬ motest ages. It is only, however, during its possession by Ptolemy, and when it was called Ptolemais, that history gives any certain account of it. It was known during those ancient times to be a great city; and although no perfect monument of its grandeur now remains, yet throughout the modern town are seen fine marble and granite pillars, used at the thresholds of door-ways, or in the other parts of ordinary buildings, or lying neglected on the ground. When the empire of the Romans began to extend over Asia, Ptolemais came into their posses¬ sion ; and it yielded in like manner to the growing power of the Saracens. They were expelled from it in 1192 by Richard I. of England and Philip of France, who pur¬ chased this conquest by the sacrifice of 100,000 troops. They gave the town to the knights of St John of Jeru¬ salem, and it afterwards became the principal scene of contest between the Crusaders and the Saracens. In 1187 it was recovered from the Christians by Saladin, sultan of Egypt; and after a siege of three years was re¬ taken by the Christians, in whose possession it remained during a whole century. It was at this time a large and extensive city, on the direct route to Jerusalem, and a place of great resort. It was accordingly populous and wealthy, and contained numerous churches, convents, and hospitals, of which no traces now remain. The city was under a peculiar system of government, being ruled by all the Christian powers both of Europe and Asia, 19 of whom exercised independent authority within its bounds. It was taken by the Saracens after a bloody siege in 1291, during which it suffered severely, and afterwards fell into decay. So late as the year 1696, Maundrell, who visited it, states that it had never recovered from its last over¬ throw ; and that, with the exception of the residences of the French factors, a mosque, and a few poor cottages, it presented a vast and spacious scene of ruin. Since this period Acre has again become a considerable city; within the last 30 years it has been enlarged, and at the same time strengthened and improved. The last siege to which it was exposed was the celebrated one in 1799, lyhen it was attacked by the French under Buonaparte; but was gallantly defended by the Turks, animated by the example and advice of Sir Sydney Smith. During the siege the French succeeded in making repeated breaches in the 126 A C R Acre, walls, through which they rushed to the assault with the most desperate bravery; but they were as often repulsed with dreadful carnage by the Turks and their gallant allies, and finally abandoned the attempt on the 20th of May, after they had continued the siege for 61 days. The town is situated at the extremity of a plain on the edge of the sea-shore, and at the point of a bay formed by the promontory of Mount Carmel on the south-west, and the termination of the plain itself on the north-east. This bay faces the north-west, and from Cape Carmel to the city it may be about ten miles across. The bay affords no shelter in bad weather, being open to the north-west winds, which blow violently on the coast; and the port of Acre is a small hollow basin behind a ruined mole, scarcely capable of containing a dozen of boats. Vessels coming to this coast, therefore, either to load or discharge their cargoes, generally frequent the road of Caipha, a place of anchorage at the bottom of the bay, near which the river Kishon flows into the sea. The town, on the sides which face towards the sea, is inclosed by a single wall which on the north-west ranges along a sandy beach, and is unfortified; on the south-west side it is built on rocks washed by the sea, and is mounted with 40 pieces of can¬ non, chiefly brass. The north-east and south-east sides, which face towards the land, are surrounded by a double wall and ditch. The outer wall, which is but of very indifferent workmanship, is from 30 to 40 feet in height, provided with semicircular bastions at stated distances, and with embrasures for cannon ; and it is further strength¬ ened by a dry ditch, from 15 to 20 feet in depth, and 20 to 25 in breadth. The outer walls are the w'ork of Djez- zar Pacha, who, after the expulsion of the French from Syria, was at great pains to improve the fortifications ot the place. On the outer and inner walls are planted from 100 to 120 pieces of cannon. The only gate of en¬ trance into the city is on the south-east front near the sea, where is a Turkish cemeterj^ and a small garden. The town presents in the interior that incongruous ap¬ pearance of gaudy splendour and extreme wretchedness which is so common in all the cities of the East. Among the chief buildings may be reckoned an extensive palace of Suliman Pacha, with spacious courts, fountains, &c. Opposite to this is a fine mosque, built also by him, the lofty dome and minaret of which are conspicuous from a distance, and another palace of Ali Pacha. These build¬ ings have all a fountain near them in the public street, inclosed by a brass-work frame. They are highly orna¬ mented, and executed in the style common at Constanti¬ nople. The other mosques, which are six in number, are built in the same fashion as that of Suliman Pacha; but they are of a smaller size, and are every pne of them sur¬ mounted by the crescent. The other religious edifices are a Catholic convent, a Greek church, and a Maronite place of worship. The Jews have also a synagogue. Of the bazaars, besides several ordinary ones, there are two long ranges covered in by an arched roof, and light¬ ed from above. They are paved with flag-stones, have benches on each side, and afford shelter both from the sun and rain. The property deposited is secured by two large gates, which are closed at each end. They are well supplied with provisions, and at a moderate price. The old khane, or caravansary, is one of the best that is anywhere to be seen. It consists in general of a large square court, with a fine marble fountain in the centre, a piazza of arcades going round the whole, and galleries above, containing rooms for strangers. These galleries are furnished with lattice-work balconies, or projecting windows, quite in the Arabian style. The whole edifice, A C R from the peculiar style and furnishing of its ornaments Acre and construction, maybe considered as most interesting, and the only perfect memorial of Saracen architecture still remaining in the place. Besides the inn allotted to the Franks, there are several others throughout the town occupied by Christians of different sects, all resembling caravansaries in their arrangement. There are also many spacious and well-built magazines, particularly one constructed by the pacha, having a paved court in the centre, surrounded by a piazza of arcades, consisting of about 40 granite pillars, taken from the ruins of the an¬ cient city. The private dwellings are all of stone, diffeiv ing in size and plan. The roofs are invariably flat, and provided with terraces for taking the air in the evenings of summer. The streets are in general narrow and dirty; only one or two are of any tolerable breadth. Many of them are paved. Near the north-western extremity of the town is a large space covered with ruined buildings, heaps of rubbish, and an accumulation of rain water. The popu¬ lation of Acre consists, one-half of Mahometans, in equal portions of Arabs and Turks; one-fourth of Christians of different persuasions ; and one-fourth of Jews. Acre re¬ tains scarcely any memorials of its ancient state. The Sa¬ racenic remains are only partially to be traced in the inner walls of the town, which have been so often broken down and repaired as to preserve few traces of the original work. All the mosques, fountains, bazaars, and other buildings, with the exception of the caravansary already mentioned, are in a style rather Turkish than Arabic. The Christian ruins are altogether gone. There is not the slightest trace of any of the magnificent churches and convents described by Maundrell. Even the three Gothic arches mentioned by Dr Clarke, and called by the English sailors King Richard’s Palace, have been razed to the ground. It is not easy to ascertain the causes which have swept away s? .m.any traces of the ancient city between Maundrell’s visit in 1696, and Dr Clarke’s in 1801; but the subsequent destruction was occasioned by Djezzar Pacha, when he was improving the fortifications of the town. The trade of Acre consists in the export of cotton, and in the im¬ portation of manufactures for the consumption of the sur¬ rounding country. It is 23 miles north-north-west of Je¬ rusalem, and 27 south of Tyre. Long. 39. 25. E. Eat. 32. 40. N. Acre, in Hindostan, the same with lack, signifies the sum of 100,000 rupees; the rupee is of the value of the French crown of three livres, or 30 sols of Holland; 100 lacks of rupees make a couron in Hindostan, or 10,000,000 rupees: the pound sterling is about eight rupees, accord¬ ing to which proportion a lack of rupees amounts to L.12,500 sterling. Acre, a measure of superficies, and the principal de¬ nomination of land-measure in use throughout the whole of Great Britain. The word (formed from the Saxon acher, or the German aker, a field) did not originally signify a determinate quantity of land, but any open ground, espe¬ cially a wide campaign; and in this antique sense it seems to^ be preserved in the names of places, as Castle-acre, west-acre, &c. The English standard acre, now the im¬ perial acre of Britain, is a square raised from the basis of tfle chain of 66 feet, or 22 yards, or l-80th of a mile, len of these squares form the acre, which thus contains 4840 square yards. This is divided into roods, of which there are four in the acre; and into poles or perches, of which there are 40 in each rood, or 160 in the acre. The rood will thus measure 1210 square yards, and the pole 04 square yards, according to the following table, which contains also other denominations useful to be compared with the acre. A C R The above is the standard acre of England; but vari¬ ous customary acres are in use throughout the different counties, deviating considerably from this standard both in excess and defect, though all of them are now illegal since the act 5 George IV., which establishes the same standard throughout the whole kingdom. In Bedford¬ shire, it is sometimes only two roods ; Cheshire, formerly, and still in some places, 10,240 square yards; Cornwall, sometimes 5760 yards; Dorsetshire, generally 134 perches; Hampshire, from 107 to 120 perches, but sometimes 180; Herefordshire, two-thirds of a statute acre. The acre for hops contains 1000 plants, and is only equal to half a statute acre; for wood, again, it is 256 perches. Leicestershire, 2308f square yards ; Lincolnshire, five roods, particularly for copyhold land; Staffordshire, nearly 2£ acres ; Sus¬ sex, 107, 110, 120, 130, or 212 perches; the short acre 100 or 120 perches, the forest acre 180 perches. West¬ moreland, 6760 square yards, or 160 perches of 6-| yards square ; in some parts the Irish acre is used : Worcester, the hop acre, of 1000 stocks, 90 perches, sometimes 132 or 141 perches. In North Wales, the Brio or true acre is 4320 square yards, the Stang or customary acre 3240 square yards, as in Anglesea and Caernarvonshire, making 5^ Llathen, r=160 perches of 4^- yards square, caWed.paladr : 8 acres make an ox-land, and 8 of these a plough-land, in Pem¬ brokeshire. In South Wales the Erw varies greatly with the perch; sometimes this is nine feet square, 160 perches making one stangell, and four stangells one erw of 5760 yards; sometimes 101 feet square, making a quart or quarter of a Hath, 40 of which make a stangell, and four stangells an erw, which is thus 7840 yards, equal to the Irish acre; sometimes 11 feet, called bat or eglwys haw, making the erw 9384 yards, as in Glamorganshire, one-fifth more = 11,261 yards ; sometimes 11^- feet, called a Hath, 48 making a quarter cyvar, and four cyvars an erw of 11,776 yards; lastly, 12 feet, giving an erw of 10,240 yards, equal to the Staffordshire acre. Nothing can show more clearly than the existence of such numerous and useless diversities, the necessity of the late act for establishing a uniform standard throughout Great Britain, and which only requires to be enforced with strictness to abolish for ever every other measure. In Scot¬ land the acre is much more uniform, scarcely deviating in any part more than one per cent, from the standard. It is raised from the chain of 24 ells ; and by the verdict of the jury assembled at Edinburgh on the 4th February 1826, to determine the proportion between the existing mea¬ sures and the imperial, the ell was found, according to an accurate measurement made by Mr Jardine, civil engineer, 37,0598 inches, making the chain 74'1196 feet, and the acre 6104 square yards and •12789, &c. decimals of a yard. It is considerably larger, therefore, than the imperial acre; and as the act of uniformity establishes this latter in its stead, it makes an important change throughout Scotland, a c R 127 and it becomes necessary to know exactly the proper- Acre tions between them. The imperial, we have seen, con- II tains 4840 square yards, while the Scotish contains Acrido- 6104*12789, &c. They are to each other, therefore, as is to 1*26118345; so that 1000 acres Scotish are equal to 1261*18345 imperial; and in every case, to convert Scot¬ ish into imperial, multiply by the fraction 1*26118345: such minuteness, however, is seldom required in practice. A ready and very accurate approximation will be obtain¬ ed by reckoning one acre Scotish equal to five quarters imperial, and g^th part more. This will give the value of the acre almost to one-fourth of a square yard in defect. Hence we have this general rule : To convert Scotish acres into imperial, add one-fourth; and if that is not sufficiently mi¬ nute, add ffth more. Take, for example, 1000 acres, add one-fourth or 250, and we have 1250; add still -g^th, or 11, and we have 1261. This rule is obtained by expressing the above fraction in a series of which we take only the first three terms. It is one acre Scotish = 1 + j ^c* acres imperial. By a similar rule, it is easy to convert the Scotish money rates or prices of land into imperial: we have only to multiply the Scotish prices by the frac¬ tion 0*792906, the reciprocal of the other; or deduct one-fifth from the price, and for greater accuracy -fffh more; or ivhat is still simpler, deduct 20^ per cent, or 4s. in the pound from the Scotish prices. An estate of 1000 acres, for example, is to be let at 30s. per acre : What is the rent per imperial acre ? Deduct 4s. l£d. and the half of it for the additional 10s., and we have 6s. 2^d. less, or on the whole 23s. O^d. These rules will apply in every practical case; and for very particular and extremely accurate pur¬ poses, recourse must be had to the original fractions 0*792906 and 1*26118345. Such are the relations of the Scotish standard acre to the imperial; but until of late years, it was the practice of land-surveyors to measure with a chain of 74 feet and 4-10ths of a foot in length, the length of the ell having been erroneously estimated at 37 inches and 2-10ths of an inch. This practice increased the acre from 6104*13448 to 6150*4 square yards; it made the ratio of this acre to the imperial as 1 to 1*27074, &c.; or we may reckon one acre equal to five quarters imperial, and ^th more. When this error in the length of the chain came to be discovered, surveyors took to the chain of exactly 74) feet; this length being recommended by tbe round num¬ ber, and the nearer approach to the standard. By it the acre contains only 6084*4444, &c. yards; it is to the im¬ perial acre as 1 to 1*25711662, &c. or we make one of these acres equal to five quarters imperial, and j-^th more. In Ireland the perch, of which the acre contains as usual 160, is a square of seven yards. The acre, therefore, con¬ tains 7840 square yards. See Weights and Measures; Parliamentary Deports of the Commissioners of Weights and Measures; Act 5 Geo. IV.; and Buchanan’s Tables of Weights and Measures, where the conversions are all given ty inspection. (c.) AcRE-Fight, an old sort of duel fought by English and Scotish combatants, between the frontiers of their king¬ doms, with sword and lance: it was also called camp¬ fight, and the combatants champions, from the open field being the stage of trial. ACRIBEIA, a term purely Greek, literally denoting an exquisite or delicate accuracy; sometimes used in our language, for want of a word of equal signification. ACIIIDOPHAGI, in Ancient Geography, an Ethiopian people, represented as inhabiting near the deserts, and to have fed on locusts. This latter circumstance their name imports, the word being compounded of the Greek 128 A C R Acrisius locust, and E ebii }[u; Ecd, lib.j. cap. 2.a![ix.5. •CihUist, LU'jt. chffians, Encratites, and Apotactics. 6. The Acts of St Thomas the Apostle ; received particularly by the Mani- checans. 7. The Acts of St Philip. This book the Gnostics made use of. 8. The Acts of St Matthias. Some have imagined that the Jews for a long time had concealed the original Acts of the life and death of St Matthias, written in Hebrew; and that a monk of the abbey of St Matthias at Treves, having got them out of their hands, procured them to be translated into Latin, and published them; but the critics will not allow them to be genuine. Acts of Pilate, a relation sent by Pilate to the Empe¬ ror Tiberius, concerning Jesus Christ, his death, resurrec¬ tion, ascension, and the crimes of which he was convicted before him.1 It was a custom among the Romans, that the proconsuls and governors of provinces should draw up acts, or memoirs, of what happened in the course of their government, and send them to the emperor and senate. The genuine acts of Pilate were sent by him to Tiberius, who reported them to the senate ; but they were rejected by that assembly, because not immediately addressed to them; as is testified by Tertullian, in his Apol. cap. 5. and 20, 21. The heretics forged acts in imitation of them: in the reign of the Emperor Maximin, the Gentiles, to throw an odium on the Christian name, spread about spurious Acts of Pilate ; which the emperor, by a solemn edict, ordered to be sent into all the provinces of the em¬ pire, and enjoined the schoolmasters to teach and explain them to their scholars, and make them learn them by heart. These acts, both the genuine and the spurious, are lost. There is indeed extant, in the Pseudo-Hegesippus, a letter from Pilate to the Emepror Claudius, concerning Jesus Christ;2 but it discovers itself at first sight to be spurious. ACTiE were meadows of remarkable verdure and luxuriancy near the sea-shore, where the Romans used to indulge themselves to a great degree in softness and deli¬ cacy of living. The word is used in this sense by Cicero and Virgil; but Vossius thinks it can only be used in speaking of Sicily, as these two authors did. ACTtEA, Herb-Christopher, or Bane-Berries. ACTfEON, in fabulous history, the son of Ar.istaeus and Autonde; a great hunter. He was transformed by Diana into a stag, because he looked on her while bathing; and was devoured by his own dogs. The effect of imper¬ tinent curiosity and expensive pleasures seem to be the moral of the fable. ACTIAN Games, in Roman antiquity, were solemn games instituted by Augustus, in memory of his victory over Mark Antony at Actium, held every fifth year, and celebrated in honour of Apollo, since called Actius. Hence Actian Years, an era commencing from the battle of Actium, called the Era of Augustus. Virgil insinuates them to have been instituted by TEneas, from that pas¬ sage, iEn. iii. v. 280: Actiaque Iliads celebramus littora ludis. But this he only does by way of compliment to Augustus ; attributing that to the hero from whom he descended, which was done by the emperor himself; as is observed by Servius. ACTINIA, in Zoologig, a genus belonging to the order of Vermes mollusca, called Animal Flowers and Sea Anemonies. ACTIO, in Roman antiquities, an action at law in a court of justice. The formalities used by the Romans, in judicial actions, were these : If the difference failed to be made up by friends, the injured person proceeded in jus reum vocare, to summon the offending party to the court, who was obliged to go, or give bond for his appearance. The offending party might be summoned into court viva Actio voce, by the plantiff himself meeting the defendant, declar- II ing his intention to him, and commanding him to go be- •A■ctlon■ fore the magistrate and make his defence. If he would not go willingly, he might drag and force him along, un¬ less he gave security for his appearance on some appoint¬ ed day. If he failed to appear on the day agreed on, then the plaintiff, whensoever he met him, might take him along with him by force, calling any by-standers to bear witness, by asking them visne antestari ? The by-standers upon this turned their ear toward him in token of their consent. To this Horace alludes in his satire against the impertinent, lib. i. sat. 9. Both parties being met before the pretor, or other su¬ preme magistrate presiding in the court, the plaintiff pro¬ posed the action to the defendant, in which he designed to prosecute him. This they termed edere actionem ; and was commonly performed by writing it in a tablet, and offering it to the defendant, that he might see whether he had better stand the suit or compound. In the next place came the postulatio actionis, or the plaintiff’s petition to the pretor for leave to prosecute the defendant in such an action. The petition was granted by writing at the bottom of it actionem do, or refused by writing in the same manner actionem non do. The petition being granted, the plaintiff vadabatur reum, i. e. obliged him to give sureties for his appearance on such a day in the court; and this was all that was done in public before the day fixed upon for the trial. In the mean time, the difference was often made up either transactione, by letting the cause fall as dubious; or pactione, by composition for damages amongst friends. On the day appointed for hearing, the pretor ordered the several bills to be read, and the parties summoned by an accensus, or beadle. Upon the non-appearance of either party, the defaulter lost his cause : if they both appeared, they were said se stetisse ; and then the plaintiff proceeded litem sive actio¬ nem intendere, i. e. to prefer his suit; which was done in a set form of words, varying according to the difference of the actions. After this the plaintiff desired judgment of the pretor, that is, to be allowed a judex or arbiter, else the recuperatores or centumviri. These he requested for the hearing and deciding the business : but none of them could be desired but by the consent of both parties. The pretor, having assigned them their judges, defined and determined the number of witnesses to be admitted, to hinder the protracting of the suit; and then the parties proceeded to give their caution, that the judgment, what¬ ever it was, should stand and be performed on both sides. The judges took a solemn oath to be impartial; and the parties took the juramentum calumnies. Then the trial began with the assistance of witnesses, writings, &c. which was called disceptatio causcc. ACTION, in a general sense, implies nearly the same thing with Act. Grammarians, however, observe some distinction between action and act; the former being ge¬ nerally restricted to the common or ordinary transactions, whereas the latter is used to express those which are re¬ markable. Thus, we say it is a good action to comfort the unhappy; it is a generous act to deprive ourselves of what is necessary for their sake. The wise man proposes to himself an honest end in all his actions; a prince ought to mark every day of his life with some act of greatness. The Abbe Girard makes a further distinction between the words action and act. The former, according to him, has more relation to the power that acts than the latter; whereas the latter has more relation to the effect pro¬ duced than the former; and hence the one is properly the 132 ACT Action, attribute of the other. Thus, we may properly say, “ Be sure to preserve a presence of mind in all your actions, and take care that they be all acts of equity." Action, in Commerce, is a term used abroad for a cer¬ tain part or share of a public company’s capital stock. Thus, if a company has 400,000 livres capital stock, this may be divided into 400 actions, each consisting of 1000 livres. Hence a man is said to have two, four, &c. actions, according as he has property of 2000, 4000, &c. livres capital stock. The transferring of actions abroad is per¬ formed much in the same manner as stocks are with us. Action, in Mechanics, implies either the effort which a body or power makes against another body or power, or the effect itself of that effort. As it is necessary, in works of this kind, to have a par¬ ticular regard to the common language of mechanics and philosophers, we have given this double definition ; but the proper signification of the term is the motion which a body really produces, or tends to produce, in another; that is, such is the motion it would have produced had nothing hindered its effect. All power is nothing more than a body actually in mo¬ tion, or which tends to move itself; that is, a body which would move itself if nothing opposed it. The action therefore of a body is rendered evident to us by its mo¬ tion only; and consequently we must not fix any other idea to the word action than that of actual motion, or a simple tendency to motion. The famous question relat¬ ing to vis viva and vis mortua owes, in all probability, its existence to an inadequate idea of the word action ; for had Leibnitz and his followers observed that the only precise and distinct idea we can give to the word force or action reduces it to its effect, that is, to the motion it actually produces or tends to produce, they would never have made that curious distinction. Quantity of Action, a name given by M. de Mauper- tuis, in the Memoirs of the Parisian Academy of Sciences for 1744, and those of Berlin for 1746, to the product of the mass of a body by the space which it runs through, and by its celerity. He lays it down as a general law, that, “ in the changes made in the state of a body, the quantity of action necessary to produce such change is the least possible.” This principle he applies to the in¬ vestigation of the laws of refraction, of equilibrium, &c. and even to the ways of acting employed by the Supreme Being. In this manner M. de Maupertuis attempts to connect the metaphysics of final causes with the funda¬ mental truths of mechanics; to show the dependence of the collision of both elastic and hard bodies upon one and the same law, which before had always been referred to separate laws; and to reduce the laws of motion and those of equilibrium to one and the same principle. Action, in Law, is a demand made before a judge for obtaining what we are legally entitled to demand, and is more commonly known by the name of law-suit or process. Action, in Oratory, is the outward department of the orator, or the accommodation of his countenance, voice, and gesture, to the subject of which he is treating. Action, in Painting and Sculpture, is the attitude or position of the several parts of the face, body, and limbs, of such figures as are represented, and whereby they seem to be really actuated by passions. Thus, we say, the action of such a figure finely expresses the passions with which it is agitated; we also use the same expression with regard to animals. Action, in Physiology, is applied to the functions of the body, whether vital, animal, or natural The vital tunctions, or actions, are those which are absolutely necessary to life, and without which there is no life; ACT as the action of the heart, lungs, and arteries. On the Ac action and re-action of the solids and fluids on each other, depend the vital functions. The pulse and respiration are the external signs of life. Vital diseases are all^ those which hinder the influx of the venous blood into the cavities of the heart, and the expulsion of the arterial blood from the same.—The natural functions are those which are instrumental in repairing the several losses which the body sustains ; for life is destructive of itself, its very offices occasioning a perpetual waste. The man- ducation of food, the deglutition and digestion thereof, also the separation and distribution of the chyle and ex- crementitious parts, &c. are under the head of natural functions, as by these our aliment is converted into our nature. They are necessary to the continuance of our bodies.—The animal functions are those which we per¬ form at will, as muscular motion, and all .the voluntary actions of the body : they are those which constitute the senses of touch, taste, smell, sight, hearing, perception, reasoning, imagination, memory, judgment, affections of the mind. Without any or all of them a man may live, but not so comfortably as with them. Action, in Poetry, the same with subject or fable. Critics generally distinguish two kinds, the principal and the incidental. The principal action is what is generally called the fable, and the incidental an episode. ACTIONARY, or Actionist, a proprietor of stock in a trading company. ACTIVE denotes something that communicates action or motion to another; in which acceptation it stands op¬ posed to passive. Active, in Grammar, is applied to such words as ex¬ press action, and is therefore opposed to passive. The active performs the action, as the passive receives it. Thus we say, a verb active, a conjugation active, &c. or an active participle. Active Verbs are such as do not only signify doing, or acting, but have also nouns following them, to be the sub¬ ject of the action or impression. Thus, to love, to teach, are verbs active ; because we can say, to love a thing, to teach a man. Neuter verbs also denote an action, but are distinguished from active verbs, in that they cannot have a noun following them: such are, to sleep, to go, &c. Some grammarians, however, make three kinds of active verbs; the transitive, where the action passes into a subject different from the agent; reflected, where the action returns upon the agent; and reciprocal, where the action returns mutually upon the two agents who pro¬ duced it. ACTIVITY, in general, denotes the power of acting, or the active faculty. Sphere of Activity, the whole space in which the virtue, power, or influence of any object is exerted. ACTIUM, in Ancient Geography, a town situated on the coast of Acarnania, in itself inconsiderable, but famous for a temple of Apollo, a Safe harbour, and an adjoining promontory of the same name, in the mouth of the Sinus Ambracius, opposite to Nicopolis, on the other side of the bay. It became famous on account of Augustus’s victory over Antony and Cleopatra, and for quinquennial games instituted there, called Actia, or Ludi Actiaci. Hence the epithet Actius, given to Apollo. (Virgil.) Actiaca cera, a computation of time from the battle of Actium. ACTIUS, in mythology, a surname of Apollo, from Actium, where he was worshipped. ACTON, a large village in the county of Middlesex and hundred of Ossulton, about five miles from London. It was formerly frequented on account of some saline springs, which have now fallen into disuse. The grand ACT A r junction canal, in its way from Uxbridge to London, passes through the parish. It is a rectory in the patron- 1 AcU'te. Le of the bishop of London. The number of inhabitants 'were, in 1801, 1425; in 1811, 1674; and in 1821, 1929. ACTOR, in general, signifies a person who acts or per¬ forms something. Actor, among Civilians, the proctor or advocate in civil courts or causes; as Actor ecclesicc has been some¬ times used for the advocate of the church, actor dominicus for the lord’s attorney, actor villce for the steward or head bailiff of a village. Actor, in the Drama, is a person who represents some part or character. See Drama. Actors were highly honoured at Athens: at Rome they were despised, and not only denied all rank among the citizens, but even when any citizen appeared upon the stage, he was expelled his tribe, and deprived of the right of suffrage by censors. The French have in this respect adopted the ideas of the Romans; the English those of the Greeks. Women actors were unknown to the ancients, among whom men always performed the female character; and hence one reason for the use of masks among them. Actresses are by some said not to have been introduced on the English stage till after the restoration of King Charles II. who has been charged with contributing to the corrupting of our manners by importing this usage from abroad. But this can be but partly true, for Prynne, in his Histriornastix, speaks of women actors as prostitutes ; which, as the queen of Charles I. sometimes acted in the court dramas, was one occasion of the severe prosecution brought against him for that book. See Bibliography, sect. 6. Actor, the name of several persons in fabulous history. One Actor among the Aurunci is described by Virgil as a hero of the first rank. (2En. xii.) ACTORUM Tabulae, in antiquity, were tables insti¬ tuted by Servius Tullius, in which the births of children were registered. They were kept in the treasury of Saturn. ACTUAL, something that is real and effective, or that exists truly and absolutely. Thus, philosophers use the terms actual heat, actual cold, &c. in opposition to virtual or potential. Hence, among physicians, a red-hot iron, or fire, is called an actual cautery, in distinction from cau¬ teries, or caustics, that have the power of producing the same effect upon the animal solids as actual fire, and are czWeA. potential cauteries. Boiling water is actually hot; brandy, producing heat in the body, is potentially hot, though of itself cold. Actual Sin, that which is committed by the person himself, in opposition to original sin, or that which he contracted from being a child of Adam. ACTUARLE Naves, a kind of long and light ships among the Romans, thus denominated because they were chiefly designed for swiftness and expedition. They correspond to what the French call brigantines. ACTUARIUS, a celebrated Greek physician of the thirteenth century, and the first Greek author who has treated of mild purgatives, such as cassia, manna, senna, &c. He is the first also who mentions distilled waters. His works were printed in one volume folio, by Henry Stephens, in 1567. Actuarius, or Actarius, a notary, or officer, appoint¬ ed to write the acts or proceedings of a court, or the like. In the eastern empire, the actuarii were properly officers who kept the military accounts, received the corn from the susceptores, or storekeepers, and delivered it to the soldiers. ACTUATE, to bring into act, or put a thing in action. Thus an agent is said, by the schoolmen, to actuate a power, when it produces an act in a subject. Thus the A C U 133 mind may be said to actuate the body; and thus a medi- Actus cine is said, by ancient physicians, to be actuated or ,11 brought into action, when by means of the vital heat it is Acus- made to produce its effect. ACTUS, in Ancient Architecture, a measure, in length equal to 120 Roman feet. In Ancient Agriculture the word signified the length of one furrow, or the distance a plough goes before it turns. Actus Intervicinalis, a space of ground four feet in breadth, left between the lands as a path or way. Actus Major, or Actus Quadratus, a piece of ground in a square form, whose side was equal to 120 feet, equal to half the jugerum. Actus Minimus was a quantity of land 120 feet in length and four in breadth. ACUANITES, in Ecclesiastical History, the same with those called more frequently Manichees. They took the name from Acua, a disciple of Thomas, one of the twelve apostles. ACULEATE, or Aculeati, a term applied to any plant or animal armed with prickles. ACULEI, the prickles of animals or of plants. ACULER, in the Manege, is used for the motion of a horse when, in working upon volts, he does not go far enough forward at every time or motion, so that his shoul¬ ders embrace or take in too little ground, and his croupe comes too near the centre of the volt. Horses are natu¬ rally inclined to this fault in making demi-volts. ACUMINA, in Antiquity, a kind of military omen, most generally supposed to have been taken from the points or edges of darts, swords, or other weapons. ACUNA, Christopher de, a Spanish Jesuit, born at Burgos. He was admitted into the society in 1612, being then but 15 years of age. After having devoted some years to study, he went to America, where he assisted in making converts in Chili and Peru. In 1640 he returned to Spain, and gave the king an account how far he had succeeded in the commission he had received to make discoveries on the river of the Amazons; and the year following he published, at Madrid, in a quarto volume, a description of this river, entitled Nuevo Descubri- miento del Gran Rio de las Amazonas. He was ten months together upon this river, having had instruc¬ tions to inquire into every thing with the greatest exactness, that his Majesty might thereby be enabled to render the navigation more easy and commodious. He went aboard a ship at Quito with Peter Texiera, who had already been so far up the river, and was therefore thought a proper person to accompany him in this expedition. They embarked in February 1639, but did not arrive at Para till the December following. It is thought that the revolution of Portugal, by which the Spaniards lost Bra¬ zil, and the colony of Para, at the mouth of the river of the Amazons, led to the suppression of Acuna’s narrative; for, as it could not be of any advantage to the Spaniards, they were afraid it might prove of service to the Portuguese, by instructing them in the navigation of that great river. M. de Gomberville, the possessor of one of the few copies that escaped, published a French translation at Paris in * 1682, in 2 vols. 12mo. Acuna appears to have returned to Peru, and to have died there; but the year of his death is uncertain. ACUPUNCTURE, the name of a surgical operation among the Chinese and Japanese, which is performed by pricking the part affected with a silver needle. They employ this operation in headachs, lethargies, convulsions, colics, &c. ACUS, in Ichthyology, the trivial name of a species of Syngnathus. 134 ADA ADA Acute Adam. ACUTE, an epithet applied to such things as terminate in a sharp point or edge; and in this sense it stands op¬ posed to obtuse. AcuTE-angled, in Geometry, is that which is less than a right angle, or which does not subtend 90 degrees. AcuTE-angled Cone is, according to the ancients, a right cone, whose axis makes an acute angle with its side. AcuTE-angled Triangle is a triangle whose three angles are all acute. Acute Diseases, such as come suddenly to a crisis. This term is used for all diseases which do not fall under the head of chronic diseases. Acute, in Music, is applied to a sound or tone that is sharp or high in comparison of some other tone. In this sense, acute stands opposed to grave. ACUTIATOR, in writers of the barbarous ages, denotes a person that whets or grinds cutting instruments; called also in ancient glossaries acutor, ay.cv^r^g, samiarius, cotia- rius, &c. In the ancient armies there were acutiatores, a kind of smiths, retained for whetting or keeping the arms sharp. AD, a Latin preposition, originally signifying to, and frequently used in composition both with and without the d, to express the relation of one thing to another. Ad Bestias, in antiquity, is the punishment of criminals condemned to be thrown to wild beasts. Ad Hominem, in Logic, a kind of argument drawn from the principles or prejudices of those with whom we argue. Ad Ludos, in antiquity, a sentence upon criminals among the Romans, whereby they were condemned to entertain the people by fighting either with wild beasts or with one another, and thus executing justice upon themselves. Ad Metalla, in antiquity, the punishment of such cri¬ minals as were condemned to the mines, among the Ro¬ mans ; and therefore called Metallici. Ad Valorem, a term chiefly used in speaking of the duties or customs paid for certain goods. The duties on some articles are paid by the number, weight, measure, tale, &c.; and others are paid ad valorem, that is, accord¬ ing to their value. ADAGE, a proverb, or short sentence, containing some wise observation or popular saying. Erasmus has made a very large and valuable collection of the Greek and Ro¬ man adages; and Mr Ray has done the same with regard to the English. We have also Kelly’s Collection of Scots Proverbs. ADAGIO, in Music. Adverbially, it signifies softly, leisurely ; and is used to denote the slowest of all times. Used substantively, it signifies a slow movement. Some¬ times this word is repeated, as adagio, adagio, to denote a still greater retardation in time of the music. ADALIDES, in the Spanish policy, are officers of jus¬ tice, for matters touching the military forces. In the laws of King Alphonsus, the adalides are spoken of as of¬ ficers appointed to guide and direct the' marching of the forces in time of war. ADAM, the first of the human race, was formed by the Almighty on the sixth day of the creation. His body was made of the dust of the earth ; after which, God animat¬ ed or gave it life, and Adam then became a rational crea¬ ture. His heavenly Parent did not leave his offspring in a destitute state to shift for himself, but planted a gar¬ den, in which he caused to grow not only every tree that was proper for producing food, but likewise such as were agreeable to the eye, or merely ornamental. In this gar¬ den were assembled all the brute creation, and, by their Maker, caused to pass before Adam, who gave all of them names, which were judged proper by the Deity himself. In this review Adam found none for a companion to him¬ self. This solitary state was seen by the Deity to be at-C^ tended with some degree of unhappiness, and therefore he threw Adam into a deep sleep, in which condition he took a rib from his side, and, healing up the wound, formed a woman of the rib he had taken out. On Adam’s awak¬ ing, the woman was brought to him ; and he immediately knew her to be one of his own species, calling her his bone and his flesh, and giving her the name of woman, be¬ cause she was taken out of man. The first pair being thus created, God gave them au¬ thority over the inferior creation, commanding them to subdue the earth, also to increase and multiply, and fill it. They were informed of the proper food for the beasts and for them; the grass or green herbs being appointed for beasts, and fruits or seeds for man. Their proper em¬ ployment also was assigned them; namely, to dress the garden and to keep it. Though Adam was thus highly favoured and instructed by his Maker, there was a single tree, which grew in the middle of the garden, of the fruit of which they were not allowed to eat; being told that they should surely die in the day they ate of it. This tree was named the Tree of the Knowledge of Good and Evil. This prohibition, how¬ ever, they soon broke through. The woman having en¬ tered into conversation with the Serpent, was by him per¬ suaded, that by eating of the tree she should become as wise as God himself; and accordingly, being invited by the beauty of the fruit, and its desirable property of im¬ parting wisdom, she plucked and ate; giving her husband of it at the same time, who did likewise eat. Before this transgression of the divine command, Adam and his wife had no occasion for clothes, neither had they any sense of shame ; but immediately on eating the for¬ bidden fruit, they were ashamed of being naked, and made aprons of fig-leaves for themselves. On hearing the voice of God in the garden, they were terrified, and hid themselves : but being questioned by the Deity, they confessed what they had done, and received sentence ac¬ cordingly ; the man being condemned to labour, the wo¬ man to subjection to her husband, and to pain in child¬ bearing. They were now driven out of the garden, and their access to it prevented by a terrible apparition. They had clothes given them by the Deity, made of the skins of beasts. In this state Adam had several children; the names of only three of whom we are acquainted with, viz. Cain, Abel, and Seth. He died at the age of 930 years. These are all the particulars concerning Adam that we have on divine authority ; but there is a vast multitude of others, all of them conjectural, part of them downright falsehoods or absurdities. The curiosity of our readers, it is presumed, will be sufficiently gratified by the few which are here subjoined. According to the Talmudists, when Adam was created, his body was of immense magnitude. When he sinned, his stature was reduced to a hundred ells, according to some; to nine hundred cubits, according to others; who think this was done at the request of the angels, who were afraid of so gigantic a creature. According to the revelations of the famous Madame Bourignon, Adam before his fall possessed in himself theipn principles of both sexes, and the virtue or power of pro-to a ducing his like without the concurrent assistance of wo-6”111 r man. The division into two sexes, she imagined,1 was ^ the consequence of man’s sin; and now, she observes, man- you kind are become so many monsters in nature, being much feA less perfect in this respect than plants or trees, which are Aw capable of producing their like alone, and without pain or LdjKl- «ihe itimal ■ituctd as ibovjde- tcril,'. ADA misery. She even imagined, that being in an ecstasy, she saw the figure of Adam before he fell, with the manner how, by himself, he was capable of procreating other men. “ God,” says she, “ represented to my mind the beauty of the first world, and the manner how he had drawn it from the chaos: every thing was bright, transparent, and darted forth life and ineffable glory. The body of Adam was purer and more transparent than crystal, and vastly fleet; through his body were seen vessels and rivulets of light, which penetrated from the inward to the outward parts, through all his pores. In some vessels ran fluids of all kinds and colours, vastly bright, and quite diaphanous. The most ravishing harmony arose from every motion, and nothing, resisted or could annoy him. His stature was taller than the present race of men; his hair was short, curled, and of a colour inclining to black; his up¬ per lip covered with short hair; and instead of the bestial parts which modesty will not allow us to name, he was fashioned as our bodies will be in the eternal life, which I know not whether I dare reveal. In that region his nose was formed after the manner of a face, which diffused the most delicious fragrancy and perfumes; whence also men were to issue, all whose principles were inherent in him; there being in his belly a vessel where little eggs were formed, and a second vessel filled with a fluid which im¬ pregnated those eggs; and when man heated himself in the love of God, the desire he had that other creatures should exist beside himself, to praise and love God, caus¬ ed the fluid above mentioned (by means of the fire of the love of God) to drop on one or more of these eggs, with inexpressible delight; which being thus impregnated, issued, some time after, out of man by this canal,1 in the shape of an egg, whence a perfect man was hatched by insensible degrees. Woman was formed by taking out of Adam’s side the vessels that contained the eggs ; which she still possesses, as is discovered by anatomists.” Many others have believed that Adam at his first crea¬ tion was both male and female; others, that he had two bodies joined together at the shoulders, and their faces looking opposite ways, like those of Janus. Hence, say these, when God created Eve, he had no more to do than to separate the two bodies from one another. Of all others, however, the opinion of Paracelsus seems the most ridiculous.2 Negabat primos parentes ante lapsum habuis- se partes generationi hominis necessarias ; credebat postea accessisse, ut strumam gutturi. Extravagant things are asserted concerning Adam’s knowledge. Some rabbis, indeed, have contented them¬ selves with equalling it to that of Moses and Solomon; but others have maintained that he excelled the angels themselves. Several Christians seem to be little behind these Jews in the degree of knowledge they ascribe to Adam; nothing being hid from him, according to them, except contingent events relating to futurity. One writer indeed (Pinedo) excepts politics ; but a Carthusian friar, having exhausted in favour of Aristotle every image and comparison he could think of, at last asserted that Aris¬ totle’s knowledge was as extensive as that of Adam. In consequence of this surprising knowledge with which Adam was endued, he is supposed to have been a con¬ siderable author. The Jews pretend that he wrote a book on the Creation, and another on the Deity. Some rabbis ascribe the 92d psalm to him; and in some manuscripts the Chaldee title of this psalm expressly declares that this is the song of praise which the first man repeated for the Sabbath-day. Strange stories are told concerning Adam’s children, lhat he had none in the state of innocence, is certain from Scripture ; but that his marriage with Eve was not ADA 135 consummated till after the fall, cannot be proved from Adam, thence. Some imagine, that, for many years after thek'-^v“^ fall, Adam denied himself the connubial joys by way of penance; others, that he cohabited with another woman, whose name was Lillith. The Mahometans tell us, that our first parents having been thrown headlong from the celestial paradise, Adam fell upon the isle of Ser- endib, or Ceylon, in the East Indies; and Eve on lodda, a port of the Red Sea, not far from Mecca. After a se¬ paration of upwards of 200 years, they met in Ceylon, where they multiplied: according to some Eve had twenty, according to others only eight deliveries; bringing forth at each time twins, a male and a female, who afterwards married. The rabbis imagine that Eve brought forth Cain and Abel at a birth; that Adam wept for Abel a hundred years in the valley of tears near Hebron, during which time he did not cohabit with his wife; and that this separation would probably have continued longer, had it not been forbid by the angel Gabriel. The inhabitants of Ceylon affirm, that the salt lake on the mountain of Colombo consists wholly of the tears which Eve for one hundred years together shed because of Abel’s death. Some of the Arabians tell us, that Adam was buried near Mecca, on Mount Abukobeis ; others, that Noah hav¬ ing laid his body in the ark, caused it to be carried after the deluge to Jerusalem, by Melchizedek, the son of Shem : of this opinion are the eastern Christians ; but the Persians affirm that he was.interred in the isle of Seren- dib, where his corpse was guarded by lions at the time the giants warred upon one another. Some are of opinion that he was buried at Jerusalem, on the place where Christ suffered, that so his bones might be sprinkled with the Saviour’s blood. Adam, Alexander, Rector of the High School, Edin¬ burgh, and author of several valuable works connected with Roman literature, was born on the 24th of June 1741, on a small farm which his father rented, not far from Forres, in Morayshire. He does not appear to have received any powerful direction to literary pursuits, either from the at¬ tainments of his parents or the ability of the parochial schoolmaster; but is referable to a class of men, of which Scotland can produce a very honourable list, whom the secret workings of a naturally active mind have raised above the level of their associates, and urged on to dis¬ tinction and usefulness under the severest pressure of dif¬ ficulties. The gentle treatment of an old schoolmistress first taught him to like his book; and this propensity in¬ duced his parents to consent that he should learn Latin. To the imperfect instruction which he received at the parish school, he joined indefatigable study at home, not¬ withstanding the scanty means and poor accommodation of his father’s house. Before he was sixteen, he had read the whole of Livy, in a copy of the small Elzevir edition, which he had borrowed from a neighbouring clergyman ; omitting for the present all such passages as his own sa¬ gacity and Cole’s Dictionary did not enable him to con¬ strue. It was before day-break, during the mornings of winter, and by the light of splinters of bog'-wood dug out of an adjoining moss, that he prosecuted the perusal of this difficult classic; for, as the whole family were col¬ lected round the only fire in the evening, he was prevent¬ ed by the noise from reading with any advantage; and the day-light was spent at school. In the autumn of 1757, he was a competitor for one of those bursaries, or small exhibitions, which are given by the university of Aberdeen to young men who distinguish themselves for their classical attainments; but as the prize was awarded to the best written exercises, and as Adam, with all his reading, had not yet been accustomed to write 136 Adam. ADA he was foiled by some youth who had been more fortu¬ nate in his means of instruction. About the same time Mr Watson, a relation of his mother’s, and one of the mi¬ nisters of the Canongate, sent him a tardy invitation to come to Edinburgh, “ provided he was prepared to endure every hardship for a season,”—a condition not likely to appal one who yet knew nothing of life but its hardships. The interest of Mr Watson procured him free admission to the lectures of the different professors; and as he had now also access to books in the College Library, his lite¬ rary ardour made him submit with cheerfulness to the greatest personal privations. Eighteen months of assidu¬ ous application enabled him to repair the defects of his early tuition, and to obtain, after a comparative trial of candidates, the head mastership of the foundation known by the name of Watson’s Hospital. At this period he was only nineteen, on which account the governors of the in¬ stitution limited the appointment to half a year ; but his steadiness and ability speedily removed their scruples. After holding the situation for three years, he was induc¬ ed, by the prospect of having more leisure for the prose¬ cution of his studies, to resign it, and become private tutor to the son of Mr Kincaid, a wealthy citizen, and afterwards Lord Provost of Edinburgh; and it was in consequence of this connection that he was afterwards raised to the office for which he was so eminently quali¬ fied. He taught in the High School, for the first time, in April 1765, as substitute for Mr Matheson the rector; in consequence of whose growing infirmities, an arrangement was made, by which he retired on a small annuity, to be paid from the profits of the class; and Mr Adam was con¬ firmed in the rectorship on the 8th of June 1768. From this period the history of his life is little more than the history of his professional labours and of his li¬ terary productions. No sooner was he invested with the office, than he gave himself up with entire devotion to the business of his class, and the pursuits connected with it. For forty years his day was divided with singular regu¬ larity between the public duties of teaching and that un¬ wearied research and industry in private which enabled him, amidst the incessant occupation of a High School master’s life, to give to the world such a number of ac¬ curate and laborious compilations. So entirely did these objects of public utility engross his mind, that he mixed but little with society, and considered every moment as lost that was not dedicated in some way or other to the improvement of youth. Few men certainly could adopt, with more truth and propriety, the language of Horace, both with regard to his own feelings and the objects on which he was occupied: mihi tarda fluunt ingrataqye tempera, qiue spem Consiliumque morantur agendi gnaviter id, quod ASque pauperibus prodest, locupletibus aeque, ASque, neglectum, pueris senibusque nocebit. Epist. i. 1. S3. The rector’s class, which in the High School is the most advanced of five, consisted of no more than between thirty and forty boys when Dr Adam was appointed. His celebrity as a classical teacher, joined to the progress of the country in wealth and population, continued to in¬ crease this number up to the year of his death. His class-list for that year contained 167 names,—the largest number that had ever been collected in one class, and, what is remarkable, equal to the amount of the whole five classes during the year when he first taught in the school. He performed an essential service to the literature of his country by introducing, in his own class, an addition¬ al hour of teaching for Greek and Geography; neither of which branches seems to have been contemplated in the ADA original formation of the school. The introduction of Ai Greek, which he effected a year or two after his election,^ j was regarded by some professors of the university as a ^ dangerous innovation, and an unwarrantable encroachment on the province of the Greek chair; and the measure was accordingly resisted (though, it is satisfactory to think, unsuccessfully) by the united efforts of the Senatus Aca- demicus, in a petition and representation to the town- council, drawn up and proposed by the celebrated Princi¬ pal of the university, Dr Robertson. This happened in 1772. It is not possible for a man of principle and ordinary affections to be occupied in training a large portion of the youth of his country to knowledge and virtue, without feeling a deep responsibility, and a paramount interest in their progress and welldoing. That such were Dr Adam’s feelings is proved, not less by the whole tenor of his life, than by his mode of conducting the business of his class; by the free scope and decided support he gave to talent, particularly when the possessor of it was poor and friend¬ less ; by the tender concern with which he followed his pupils into life; and by a test not the least unequivocal, the enthusiastic attachment and veneration which they entertain for his memory. In his class-room, his manner, while it imposed respect, was kindly and conciliating. He was fond of relieving the irksomeness of continued atten¬ tion by narrating curious facts and amusing anecdotes. In the latter part of his life, he was perhaps too often the hero of his own tale; but there was something amiable even in this weakness, which arose from the vanity of hav¬ ing done much good, and was totally unmixed with any alloy of selfishness. Dr Adam’s first publication was his Grammar, which appeared in 1772. He had two principal objects in com¬ piling it;—to combine the study of English and Latin grammar, so that they might mutually illustrate each other; and to supersede the preposterous method of teach¬ ing Latin by a grammar composed in that language, and of overloading the memory with rules in Latin hexame¬ ters, for almost every fact and every anomaly in its gram¬ matical structure. The change he proposed, reasonable as it was, could not be effected without running counter to confirmed prejudices, and interfering with established books. Although, therefore, the grammar met with the approbation of some eminently good judges, particularly of Bishop Lowth, the author had no sooner adopted it in his own class, and recommended it to others, than a host of enemies rose up against him, and he was involved in much altercation and vexatious hostility with the town- council and the four under masters. Dr George Stewart, then professor of humanity, was related to Ruddiman, whose grammar Dr Adam’s was intended to supersede; and to this cause may be traced the commencement of the determined opposition that was long made to any change. In these squabbles, the acrimony displayed by some of his adversaries now and then altered the natural suavity of Dr Adam’s temper; and his high notions of in¬ dependence, and contempt of presumptuous ignorance, led him perhaps to neglect too much those easy arts of conciliation, which enable a man, witliout the slightest com- promise of his integrity, “ to win his way by yielding to His work on Roman Antiquities was published in 1791, and has contributed, more than any of his other produc¬ tions, to give him a name as a classical scholar. The vast variety ol matter, the minuteness and accuracy of the de¬ tails, the number and fidelity of the references, the con¬ stant bearing the work has upon the classics, and the light it throws on them at every step, were soon perceived and ADA am. appreciated over the whole island. These solid excellen- /-v_/'cies abundantly compensate for a certain air of heaviness, and the absence of the lighter graces of interesting style and manner. His reader follows him as he would do a faithful guide, through a strange and difficult country, with a feeling of perfect assurance that he will arrive at the end of his journey, if not by the pleasantest road, at least by the most direct and secure. The Roman Anti¬ quities is now adopted as a class-book in many of the English schools; and, even in those where the influence of custom opposes innovation, it is found in every master’s library, and recommended by him to his advanced pupils for private reading and reference. In 1794 he published his Summary of Geography a7id History, in one thick 8vo volume of 900 pages, which had grown in his hands to this size from a small treatise on the same subject, printed for the use of his pupils in 1784. The object of this work was to connect the study of the classics with that of general knowledge ; and it ac¬ cordingly contains a curious compound of interesting mat¬ ter, unwieldy as a school-book, and not always arranged in the most luminous or engaging order, but valuable to the young student for its succinct account of the first principles of astronomical, mathematical, and physical science, and for the mass it contains of geographical and historical information, especially with regard to the fabu¬ lous ages of antiquity. His Classical Biography, published in 1800, is the least in request of all his works; a circumstance owing, per¬ haps, to the more comprehensive and popular plan of Lempriere’s Classical Dictionary. It exhibits, however, ample proofs of well-directed industry; and in the number and unfailing accuracy of the references, furnishes an ex¬ cellent index to the best sources of information, even where the book itself may be thought meagre and scanty. His last work was his Latin Dictionary, which appear¬ ed in 1805, printed, like every other production of his pen, in the most unassuming form, and with the utmost anxiety to condense the greatest quantity of useful know¬ ledge into the smallest bulk, andlafford it to the student at the cheapest rate. It was intended chiefly for the use ot schools, and to be followed by a larger work, contain¬ ing copious illustrations of every word in the language. Ihe character which he had acquired by his former works for patient research and correct detail stamped a high and deserved authority on this book. The clear account of the different meanings of words, the explanation of idioms, and happy translation of difficult passages, which abound, particularly in the latter half, are admirably well adapted to remove the difficulties of the younger student, and render the work, notwithstanding the modesty of its pretensions, equally valuable to the more advanced. It is much to be regretted he did not live to complete his larger work on the extended scale on which the latter part of the small one is executed. He had proceeded as far as the word Comburo, with a plenitude of illustration that would have made the work a treasure of Latinity, when he was seized in school with an apoplectic affection ; oc¬ casioned, perhaps, by the intenseness of his application, and the small portion of sleep he allowed himself,—certain¬ ly not by his mode of living, which was simple and ab¬ stemious to an extreme degree. He lingered five days under the disease. Amidst the wanderings of mind that accompanied it, he was constantly reverting to the busi¬ ness of the class, and addressing his boys ; and in the last hour of his life, as he fancied himself examining on the lesson of the day, he stopped short, and said, “ But it grows dark, you may goand almost immediately expired. He died on the 18th of December 1809, at the age of 68. VOL. II. ADA 137 The magistrates of Edinburgh, whose predecessors had Adam, not always been alive to his merits, showed their respect for his memory by a public funeral. A short time before his death, he was solicited by some of his old pupils to sit to Mr Raeburn for his portrait, which was executed in the best style of that eminent artist, and placed, as a memo¬ rial of their gratitude and respect, in the library of the High School. He was twice married; first in 1775, to Miss Munro, eldest daughter of the minister of Kinloss, by whom he had several children, the last of whom died within a few days of his father; and in 1789, to Miss Cosser, daughter of Mr Cosser, Comptroller of Excise, who, with two daughters and a son, are still alive. (h.) Adam, Melchior, lived in the seventeenth century. He was born in the territory of Grotkaw in Silesia, and edu¬ cated in the college of Brieg, where he became a firm Protestant, and was enabled to pursue his studies by the liberality of a person of quality, wdio had left several ex¬ hibitions for young students. He was appointed rector of a college at Heidelberg, where he published, in the year 1615, the first volume of his Vitce Germanorum Phi- losophorum, &c. This volume, which treated of philoso¬ phers, poets, writers on polite literature, and historians, &c. was followed by three others : that which treated of divines was printed in 1619; that of the lawyers came next; and, finally, that of the physicians : the last two were published in 1620. All the learned men whose lives are contained in these four volumes lived in the sixteenth or beginning of the seventeenth century, and are either Germans or Flemings ; but he published in 1618 the lives of twenty divines of other countries in a separate vo¬ lume, entitled Decades duce, continentes Vitas Theologorum exterorum principum. All his divines are Protestants. The Lutherans were not pleased with him, for they thought him partial, and will not allow his work to be a proper standard of the learning of Germany. He was the author of some other works of less consequence than his Lives. His industry as a biographer is commended by Bayle, who acknowledges his obligations to his labours. He died in 1622. Adam, Robert, an eminent architect, was born at Edin¬ burgh in the year 1728. He was the second son of Wil¬ liam Adam, Esq. of Maryburgh, in the county of Fife, who has also left some respectable specimens of his genius and abilities as an architect in Plopetoun-house and the Royal Infirmary of Edinburgh, which were erect¬ ed from designs executed by him. And it was perhaps owing to the fortunate circumstance of his father’s exam¬ ple that young Adam first directed his attention to those studies, in the prosecution of which he aftenvards rose to such distinguished celebrity. He received his education at the university of Edinburgh, where he had an opportunity of improving and enlarging his mind, by the conversation and acquaintance of some of the first literary characters of the age, who were then rising into reputation, or have since established their fame as historians and philosophers. Among these were Mr Hume, Dr Robertson, Dr Smith, and Dr Ferguson, who were the friends and companions of the father, and who continued through life their friend¬ ship and attachment to the son. In the year 1754, Mr Adam travelled to the Continent, with a view to extend his knowledge and improve his taste in architecture, and resided in Italy for three years. Here he surveyed and studied those noble specimens of ancient grandeur which the magnificent public edifices of the Romans, even in ruins, still exhibit. In tracing the progress of architecture and the other fine arts among the Romans, Mr Adam observed that they had visibly declined 138 ADA Adam, previously to the time of Dioclesian ; but he was also con- ' vinced that the liberal patronage and munificence of that emperor had revived, during his reign, a better taste for architecture, and had formed artists who were capable of imitating the more elegant style of a purer age. He had seen this remarkably exemplified in the public baths at Rome, which were erected by him, the most entire and the noblest of the ancient buildings. Admiring the extent and fertility of genius of the artists from whose designs such magnificent structures had been executed, he was anxious to see and study any remains that yet existed of those masters whose works were striking monuments of an elegant and improved taste, but whose names, amid the wrecks of time, have sunk into oblivion. It was with this view that he undertook a voyage to Spalatro, in Dal¬ matia, to visit and examine the private palace of Diocle¬ sian, in which that emperor resided for nine years previous to his death, and to which he retired in the year 305, when he resigned the government of the empire. Mr Adam sailed from Venice in July 1754, accompanied by M. Clerisseau, a French artist and antiquary, and two ex¬ perienced draughtsmen. On their arrival at Spalatro, they found, that though the palace had suffered much from the injuries of time, yet it had sustained no less from the dilapidations of the inhabitants to procure materials for building; and even the foundations of the ancient structure were covered with modern houses. With high expectations of success they commenced their labours, but were soon interrupted by the jealous vigilance of the government. Suspecting that their object was to view and make plans of the fortifications, an immediate and peremptory order was issued by the governor, command¬ ing them to desist. This order, however, was soon coun¬ teracted through the mediation of General Graeme, the commander-in-chief of the Venetian forces; and they were permitted to proceed in their undertaking. They resumed their labours with double ardour, and in five weeks finished plans and views of the fragments which re¬ main, from which they were enabled to execute perfect designs of the entire building. Mr Adam now returned to England, and soon rose to very considerable professional eminence. In 1762 he was , appointed architect to the king ; and the year following he presented to the public the fruit of his voyage to Spalatro, in a splendid work, containing engravings and descriptions of the ruins of the palace. “ For the account of Diocle- sian’s palace,” says Mr Gibbon, “ we are indebted to an ingenious artist of our own time and country, whom a very liberal curiosity had carried into the heart of Dalmatia. But there is room to suspect that the elegance of his designs and engravings has somewhat flattered the ob¬ jects which it was their purpose to represent. We are informed by a more recent and very judicious traveller, the Abbe Fortis, that the awful ruins of Spalatro are not less expressive of the decline of the arts than of the great¬ ness of the Roman empire in the time of Dioclesian.” Upon this we may observe, that Mr Adam allows, that previously to this period of the Roman empire the arts had visibly declined : and only contends, that the buildings erected in the reign of Dioclesian exhibit convincing proofs of the style and manner of a purer age. In the year 1768, Mr Adam obtained a seat in parlia¬ ment. He was chosen to represent the county of Kin¬ ross ; and about the same time he resigned his office of architect to the king. But he continued his professional career with increasing reputation; and about the year 1773, in conjunction with his brother James, who also rose to considerable eminence as an architect, he publish¬ ed another splendid work, consisting of plans and eleva- ADA tions of public and private buildings which were erected a from their designs. Among these are, Lord Mansfield’s l house at Caenwood; Luton-house in Bedfordshire, belong- Jdar ing to Lord Bute; the new Gateway of the Admiralty1 Office ; the Register Office at Edinburgh, &c.; which are universally admired as precious monuments of elegant de¬ sign and correct taste. The Adelphi buildings at London, which are also striking examples of the inventive genius of the Messrs Adam, proved an unsuccessful speculation. The wealth and power of a nation only were equal to so extensive an undertaking ; it was too great to be attempt¬ ed by private citizens. The buildings more lately erected from the designs of Mr Adam afford additional proofs of his invention and skill. We may mention in particular the Infirmary of Glasgow, as exhibiting the most perfect symmetry and useful disposition of parts, combined with great beauty and lightness. To the last period of his life Mr Adam displayed an increasing vigour of genius and refinement of taste; for, in the space of one year preceding his death, he designed eight great public works, besides twenty-five private buildings, so various in their style and beautiful in their composition, that they have been allowed, by the best judges, sufficient of themselves to establish his fame. The improved taste which now pretty generally prevails in our public and private edifices, undoubtedly owes much to the elegant and correct style introduced by this distin¬ guished artist. He died on the 3d of March 1792, by the bursting of a blood-vessel, in the 64th year of his age, and was buried in Westminster Abbey. The natural suavity of his man¬ ners, joined to the excellence of his moral character, se¬ cured to him the affectionate regard of his friends,* and the esteem of all who enjoyed his acquaintance.

ADA i Aims. They rejected marriage, maintaining that the conjugal Union would never have taken place upon earth had sin been unknown. This obscure and ridiculous sect did not at first last long; but it was revived, with additional absurdities, in the twelfth century, by one Tandamus, since known by the name of Tanchelin, who propagated his errors at Ant¬ werp in the reign of the emperor Henry V. He main¬ tained that there ought to be no distinction between priests and laymen, and that fornication and adultery were meritorious actions. Tanchelin had a great number of followers, and was constantly attended by 3000 of these profligates in arms. His sect did not, however, continue long after his death; but another appeared under the name of Turlupins, in Savoy and Dauphiny, where they committed the most brutal actions in open day. About the beginning of the fifteenth century, one Pi¬ card, a native of Flanders, spread these errors in Germany and Bohemia, particularly in the army of the famous Zisca, notwithstanding the severe discipline he maintain¬ ed.

Adams, John, a distinguished statesman of the United States of North America. He was born on the 19th or (new style) 30th of October 1736, in that part of the town¬ ship of Braintree, in Massachusetts, which on a subse¬ quent division was called Quincey. His parents were of that class, then abounding in New England, who united the profession of agriculture with that of some one of the mechanic arts. His ancestor Henry had emigrated from Devonshire in the year 1632, and had established himself at Braintree with six sons, all of whom married: from one descended the subject of this memoir, and from another that Samuel Adams who, with John Hancock, was by name proscribed by an act of the British parliament, for the conspicuous part he acted in the early stages of the opposition to the measures of the mother country. When about 15 years of age, his father proposed to his son John either to follow the family pursuits, and to receive m due time, as his portion, a part of the estate which they had cultivated, or to have the expense of a learned edu¬ cation bestowed upon him, with which, instead of any rortune, he was to make his way in future life. The son c lose the latter alternative ; and having received some pre- paratory instruction, was admitted a student at Howard College in the year 1751. After passing about three years in that seminary, he removed to the town of Wor¬ cester, where, according to the economical practice of that ay in New England, he became a tutor in a grammar school, and at the same time was initiated into the prac¬ tice of the law in the office of Mr Putnam, then an at- orney and a colonel of militia, and subsequently a gene¬ ral ot some celebrity in the revolutionary war. A letter of Mi Adams, which has lately come before the public, written Adams, at the early age of 19, shows a degree of forecast which,' like many other productions, may have led to its own ac¬ complishment. It is dated 12th October 1755, and says, Soon after the Reformation, a few people came over to this new world for conscience’ sake. Perhaps this appa¬ rently trivial incident may transfer the great seat of empire to America. It looks likely to me ; for if we can remove the turbulent Gallic (the French in Canada), our people, according to the exactest computation, will in another cen¬ tury become more numerous than England itself. Should this be the case, since we have, I may say, all the naval stores of the nation in our hands, it will be easy to obtain the mastery of the seas; and then the united force of all Europe will not be able to subdue us. The only way to keep us from setting up for ourselves is to disunite us. He was admitted to practice in the year 1758, and gra¬ dually rose to the degree of eminence which a local court can confer; and obtained distinction by some essays on the subject of the canon and feudal law, which were direct¬ ed to point to the rising difference which commenced be¬ tween the mother country and the colonies, soon after the' peace of 1763 had delivered the latter from all disquietude respecting the establishments of France in the adjoining province of Canada. Elis character rose, both as a law¬ yer and a patriot, so as to induce Governor Barnard, who wished to gain him over to the royal party, to offer him the office of advocate-general in the Admiralty Court, which was deemed a sure step to the highest honours of the bench. Two years after, he was chosen one of the repre¬ sentatives of his native town to the congress of the pro¬ vince. r His professional integrity was soon after exhibited in the defence of Captain Preston and some soldiers, who were tried before a Boston jury on a charge of murder. In this case Adams was counsel for the defence; and being con¬ sidered by the people, then in an inflamed state against the troops, as a determined friend of liberty, his eloquence obtained a verdict of acquittal, without lessening his popu- larity. When it was determined, in 1774, to assemble a general congress from the several colonies, Mr Adams was one of those solicited for the purpose by the people of Massa¬ chusetts. Before departing for Philadelphia to join the congress, he parted with the friend of his youth, his fel¬ low-student and associate at the bar, Jonathan Sewall, who had attained the rank of attorney-general, and was necessarily opposed to his political views. Sewall made a powerful effort to change his determination, and to deter him from going to the congress. Fie urged, that Britain was determined on her system, and was irresistible; and would be destructive to him and all those who should persevere in opposition to her designs. To this Adams replied: “ I know that Great Britain has determined on her system, and that very fact determines mfe on mine. You know I have been constant and uniform in opposition to her measures ; the die is now cast; I have passed the Rubicon ; to swim or sink, live or die, survive or perish with my country, is my unalterable determination.” The conversation was then terminated by Adams saying to his friend, “ I see we must part; and with a bleeding heart, I say, I fear for ever. But you may depend upon it, this adieu is the sharpest thorn on which I ever set my foot.” J When the continental congress was assembled, Mr Adams became one of its most active and energetic lead¬ ers. He was a member of that committee which framed the. declaration of independence, and one of the most powerful advocates for its adoption by the general body ; 140 ADA Adams, and by his eloquence obtained the unanimous suffrages of that assembly. Though he was appointed chief justice in 1776, he declined the office, in order to dedicate his talents to the general purpose of the defence of the country. In 1777, he, with three other members, was appointed a commissioner to France. He remained in Paris about a year and a half, when, in consequence of disagreements among themselves, in which Adams was not implicated, all but Franklin were recalled. In the latter end of 1779, he was charged with two commissions, one as a plenipoten¬ tiary to treat for peace, the other empowering him to form a commercial treaty with Great Britain. When arrived in Paris, the French government viewed with jealousy the purpose of the second commission; and Count de Ver- gennes advised him to keep it secret, with a view to pre¬ vail on the congress to revoke it. Mr Adams refused to communicate to the Count his instructions on that subject; and an altercation arose, from a claim made by France for a discrimination in favour of French holders of Ame¬ rican paper money in the liquidation of it. The Count complained to congress, transmitted copies of Mr Adams’ ' letters, and instructed the French minister at Philadel¬ phia to demand his recall. The demand was rejected, but afterwards four others were joined with him in the commission. Whilst these negotiations were in progress, he went to Holland, and there, in opposition to the in¬ fluence and talents of the British minister, Sir Joseph Yorke, succeeded both in negotiating a loan, and in pro¬ curing the assistance of that country in the defence against Great Britain. He formed a commercial treaty with that republic, and joined in the ephemeral association called “ the armed neutrality.” In 1785 Mr Adams was appointed ambassador to the court of his former sovereign, where his conduct was such as to secure the approbation of his own country, and the respect of that to which he was commissioned. Whilst in London, he published his work entitled De¬ fence of the American Constitution, in which he combat¬ ed ably the opinions of Turgot, Mably, and Price, in fa¬ vour of a single legislative assembly; and thus perhaps contributed to the division of power and the checks on its exercise, which became established in the United States. At the close of 1787 he returned, after ten years devoted to the public service, to America. He received the thanks of congress, and was elected soon after, under the presidency of Washington, to the office of vice-presi¬ dent. In 1790 Mr Adams gave to the public his Dis¬ courses on Davila, in which he exposed the revolutionary doctrines propagated by France and her emissaries in other countries. On the retirement of Washington, the choice of president fell on Mr Adams, who entered on that office in May 1797. At that time the government was entangled by the insolent pretensions of the French dema¬ gogues, and by their partisans in many of the states. Great differences of opinion arose between the individuals at the head of affairs: one party, with Mr Hamilton at their head, was disposed to resist the pretensions of France by open hostilities ; whilst Mr Adams was disin¬ clined to war, so long as there was a possibility of avoiding it with honour. Owing to this division of his own friends, rather than to a want of public confidence, at the conclu¬ sion of the four years for which the president is chosen, Mr Adams was not re-elected. Perhaps this was in some measure owing to the preponderance of the slave states, in which Mr Jefferson, his rival, and a proprietor of slaves, had a fellow-feeling among the chief of the people. He retired with dignity at 68 years of age to his native place, formed no political factions against those in power, but publicly expressed his approbation of the measures ADA which were pursued by him who had been his rival, who At, had become his successor in power, but had never ceased to be his firmly attached friend. i The last public occasion on which Mr Adams appeared,^ J was as a member of the convention for the revision of the constitution of Massachusetts, in which some slight altera¬ tions were requisite, in consequence of the province of Maine being separated from it. He seems to have enjoyed his mental faculties to the close of his protracted life; and even on the last day of it, two hours only before its final close, on the 4th July 1825, the fiftieth anniversary of the act of independence, he dictated to a friend, as a sentiment to be given at the public dinner of the day, “ Independence for ever.” Mr Adams was considered as a sound scholar, well versed in the ancient languages, and in many branches of general literature. His style in writing was forcible and perspicuous, and, in the latter years of his life, remark¬ ably elegant. In person he was of middling stature ; his manners spoke the courtesy of the old school; and his address, at least when he was in England, was dignified and manly. (g.)

ADAMSON, Patrick, a Scotish prelate, archbishop of St Andrews, was born in the year 1543 in the town of Perth, where he received the rudiments of his education; and afterwards studied philosophy, and took his degree of master of arts, at the university of St Andrews. In 1566 he set out for Paris as tutor to a young gentle¬ man. In the month of June of the same year, Mary Queen of Scots being delivered of a son, afterwards James YI. of Scotland and I. of England, Mr Adamson wrote a Latin poem on the occasion. In this poem he gave the prince the title of king of France and England; and this proof of his loyalty involved him in difficulties, for the French court was offended, and ordered him to be arrest¬ ed ; and he was confined for six months. He was releas¬ ed only through the intercession of Queen Mary and some of the principal nobility, who interested themselves in his behalf. As soon as he recovered his liberty, he re¬ tired with his pupil to Bourges. He was in this city dur¬ ing the massacre at Paris; and the same persecuting spirit prevailing among the Catholics at Bourges as at the metropolis, he lived concealed for seven months in a pub¬ lic house, the master of which, upwards of 70 years of age, was thrown from its top and had his brains dashed out, for his charity to heretics. Whilst Mr Adamson lay thus in his sepulchre, as he called it, he wrote his Latin poetical version of the book of Job, and his tragedy of Herod in the same language. In the year 1573, he re¬ turned to Scotland, and, having entered into holy orders, became minister of Paisley. In the year 1575, he was appointed one of the commissioners, by the general as¬ sembly, to settle the jurisdiction and policy of the church; and the following year he was named, with Mr David Lindsay, to report their proceedings to the earl of Mor¬ ton, then regent. About this time the earl appointed him one of his chaplains; and, on the death of Bishop Dou¬ glas, promoted him to the archiepiscopal see of St An¬ drews, a dignity which brought upon him great trouble and uneasiness ; for now the clamour of the Presbyterian party rose very high against him, and many inconsistent absurd stories were propagated concerning him. Soon after his promotion, he published his catechism in Latin verse, a work highly approved even by his enemies; but, nevertheless, they still continued to persecute him with great violence. In 1578 he submitted himself to the ADA ADA 141 I I A na. Aduson general assembly, which procured him peace but for a very little time ; for, the year following, fresh accusations were brought against him. In the year 1582, being at- ' tacked with a grievous disease, in which the physicians could give him no relief, he happened to take a simple medicine from an old woman, which did him service. The woman, whose name was Alison Pearson, was thereupon charged with witchcraft, and committed to prison, but es¬ caped out of her confinement; however, about four years afterwards, she was again found and burnt for a witch. In 1583 King James came to St Andrews; and the arch¬ bishop, being much recovered, preached before him, and disputed with Mr Andrew Melville, in presence of his Ma¬ jesty, with great reputation; which drew upon him fresh calumny and persecution. The king, however, was so well pleased with him, that he sent him ambassador to Queen Elizabeth, at whose court he resided for some years. His conduct during his embassy has been various¬ ly reported by different authors. Two things he princi¬ pally laboured, viz. the recommending the king his master to the nobility and gentry of England, and the procuring some support for the episcopal party in Scotland. His eloquent preaching drew after him such crowds of people, and raised in their minds so high an idea of the young king his master, that Queen Elizabeth forbade him to enter the pulpit during his stay in her dominions. In 1584 he was recalled, and sat in the parliament held in August at Edinburgh. The Presbyterian party was still very violent against the archbishop. A provincial synod was held at St Andrews in April 1586: the archbishop was here accused and excommunicated. He appealed to the king and the states, but this availed him little ; for the mob being excited against him, he durst scarcely ap¬ pear in public. At the next general assembly, a paper being produced containing the archbishop’s submission, he was absolved from the excommunication. In 1588 fresh accusations were brought against him. The year following he published the Lamentations of the prophet Jeremiah in Latin verse, which he dedicated to the king, complaining of his hard usage. In the latter end of the same year he published a translation of the Apocalypse in Latin verse, and a copy of Latin verses, addressed also to his Majesty, deploring his distress. The king, however, was not moved by his application, for the revenue of his see was granted to the duke of Lennox; so that the pre¬ late and his family were literally reduced to the want of bread. During the remaining part of his unfortunate life he was supported by charitable contribution, and he died m 1591. The character of this prelate has been various¬ ly represented, according to the sentiments of religion and politics which prevailed. But there is little doubt that lie encouraged and supported, under the authority of the king, oppressive and injurious measures. His learning was unquestioned, and he acquired great reputation as a popular preacher. In his adversity he submitted with pious resignation to his hard fate. The panegyric of the editor of his works, Mr Wilson, is extravagant and absurd. He says, that “ he was a miracle of nature, and rather seemed to be the immediate production of God Almighty, than born of a woman.” ADAMUS. The philosopher’s stone is so called by alchemists: they say it is an animal, and that it has car¬ ried its invisible Eve in its body since the moment they were united by the Creator. ADANA, a town of Asia Minor, in Natolia, and in the province of Caramania. It is situated on the river Choquen, on the banks of which stands a small but strong castle, built on a rock. It has a great number ol beautiful fountains brought from the river by means of water-works. Over the river there is a stately bridge of Adanson. fifteen arches, which leads to the water-works. The cli-^-'y'-^ mate is pleasant and healthy, and the winter mild and se¬ rene ; but the summer is so hot as to oblige the principal inhabitants to retire to the neighbouring mountains, where they spend six months among shady trees and grottos, in a most delicious manner. The adjacent country is rich and fertile, and produces melons, cucumbers, pome¬ granates, pulse, and herbs of all sorts, all the year round; besides corn, wine, and fruits in their proper season. It is 30 miles north-east of Tarsus, on the road to Aleppo. Long. 36. 12. E. Lat. 38. 10. N. ADANSON, Michael, a celebrated naturalist, wras de¬ scended from a Scotish family which had at the Revo¬ lution attached itself to the fortunes of the house of Stuart; and was born the 7th of April 1727 at Aix in Pro¬ vence, where his father was in the service of M. de Yin- timille, then archbishop of that province. On the trans¬ lation of this prelate to the archbishopric of Paris, about the year 1730, the elder Adanson also repaired thither, accompanied by his infant family of five children, all of whom were provided for by their father’s patron. A small canonry fell to the lot of our future naturalist, the revenue of which defrayed the expenses of his education at the college of Plessis. While there, he was distinguish¬ ed for great quickness of apprehension, strength of me¬ mory, and mental ardour; but his genius took no particu¬ lar bent, until he received a microscope from the celebrat¬ ed Tuberville Needham, who happened to be present at one of the public examinations, and was struck with ad¬ miration of his talents and acquirements. From the mo¬ ment that young Adanson received this donation, to the last hour of his life, he persevered, with a zeal almost un¬ exampled, in the observation and study of nature. On leaving college, his youthful ardour was well em¬ ployed in the cabinets of Reaumur and Bernard de Jus¬ sieu, as well as in the Jardin des Plantes. Such was his zeal, that he repeated the instructions of the profes¬ sors to such of his fellow-students as could not advance with a rapidity equal to his own ; and before he had completed his 19th year, he had actually described (for his own improvement) four thousand species of the three kingdoms of nature. In this way he soon exhausted the rich stores of accumulated knowledge in Europe; and having obtained a small appointment in the colony of Se¬ negal, he resigned his canonry, and embarked on the 20th of December 1748 for Africa. The motives which decided the choice of Senegal as the scene of his observations are recorded by himself, and are too remarkably indicative of his ardent thirst of know¬ ledge not to be noticed. “ It was,” says he, in a memo¬ randum found after his death, “ of all Pluropean establish¬ ments the most difficult to penetrate, the most hot, the most unhealthy, the most dangerous in every respect, and consequently the least known to naturalists.” His ardour remained unabated during the five years that he remained in Africa, in which period he collected and described an immense number of animals and plants ; delineated maps of the country, and made astronomical observations; prepared grammars and dictionaries of the languages spoken on the banks of the Senegal; kept me¬ teorological registers; composed a detailed account of all the plants of the country; and collected specimens of every object of commerce. M. Cuvier mentions that he had seen the produce and results of all these multifari¬ ous and laborious exertions. The situation in which Adanson was placed was ad¬ mirably adapted to foster originality of genius ; but it was also attended with every disadvantage that can arise from 142 ADA ' ADA Adanson. a want of comparison and rivalry.

V ^ Twenty-seven large volumes of manuscripts were employ¬ ed in displaying the general relations of all these matters, and their distribution. One hundred and fifty volumes more were occupied with the alphabetical arrangement of 40,000 species. There was also a vocabulary, which con¬ tained 200,000 words, with their explanations; and the whole was closed by a number of detached memoirs, 40,000 figures, and 30,000 specimens of the three king¬ doms of nature. The committee of the academy, to which the inspection of this enormous mass had been intrusted, warmly recommended to Adanson to separate'and publish all that was peculiarly his own, leaving out what was merely compilation: but he obstinately rejected this rea¬ sonable advice; by which means science has been depriv¬ ed of many essays, which, if we may judge from others which he at different times gave to the world, would have possessed great merit. In the midst of his scientific ardour, Adanson devoted much of his attention to a subject on which his feelings had probably been powerfully awakened during his re¬ sidence in Senegal:—we need scarcely name the slave trade. Anxious to contribute to the comforts of Europe, as well as to the security of Africa, he addressed a me¬ moir to the minister, in which he attempted to demon¬ strate that Senegal was well fitted for the production of all the valuable produce of the West Indian Archipelago, and that by suitable encouragement free negroes might be induced to engage in the cultivation of the soil. This proposition received no encouragement either from the minister or the French African Company; and as his mistaken notions of patriotism led him to reject all over¬ tures from the friends of the abolition in England, the de¬ tails of his plan still remain unknown to the world. Of Adanson’s public life little further remains to be said; for after his rejection of the proffered counsel of the academicians, he seems to have pursued his philosophic career in silent and unobtrusive retirement. Engaged in such occupations, it might have been supposed that he would have been exempted from the evils of that terrible I revolution which has been productive of so many calami¬ ties to his country and to Europe. But the case was very different. As he had devoted his life to science for its own sake, he had never made it the means of acquiring wealth; and having no patrimony from hrs ancestors, his only fortune consisted of pensions, the reward of his labours in Senegal, and the price of the specimens fur¬ nished by him to the royal cabinet. With an injustice and illiberality distinctive of revolutionary Frenchmen, the Constituent Assembly deprived this harmless man, who was known only as an. ornament to science, of what he had so hardly earned. A trifling pension from the academy still remained, and was sufficiept for his limited wants; but on the dissolution of that respectable body by the fanatical republicans, this his last resource was also anni- 1 hilated. When the revolutionary frenzy had subsided, and science again received the homage of Frenchmen, the reproachful poverty of this veteran sage was at length re¬ lieved from the public funds ; and the founders of the In¬ stitute were proud to enrol his name in the catalogue of its members. But his life was now drawing near to its close. He died, after many months of severe suffering, on the 3d of August 1806. Adanson was never married. In his will he requested, as the only decoration of his grave, a garland of flowers gathered from the fifty-eight families which he had esta¬ blished ;—“ a touching though transitory image,” says Cuvier, “ of the more durable monument which he has erected to himself in his works.” His zeal for science, his ADA 143 unwearied industry, and his talents as a philosophical ob- Adanson server, are conspicuous in all his writings. The serenity 11 of his temper, and the unaffected goodness of his heart, Adatais. endeared him to the few who knew him intimately. Onv^^>>w/ the other hand, it must be admitted, that, from early habits, he trusted too exclusively to his own talents, and would never deign to examine the discoveries of others; so that he persisted in a thousand times refuted errors, with as much pertinacity as he did in the most unquestion¬ able truths of science. Cuvier relates a remarkable in¬ stance of his contempt for every thing that did not fall within the scope of his own observations. Although he had bestowed much care on the subject of mosses, yet, in 1800, he was ignorant not only of the discoveries, but even of the very existence, of Hedwig. But though his vanity was great, it was not accompanied with any malig¬ nant feelings; and, notwithstanding his misfortunes, he was never heard to accuse any person of having contri¬ buted to inflict them. His most important works are, his Voyage to Senegal, and his Families of Plants. To the former some essays, already noticed, were subjoined; and various others were published, at different times, in the Transactions of the Academy of Sciences. The volumes for the years 1759 and 1761 contain his observations upon the Taret (a species of shell-fish exceedingly destructive to vessels), and his account of the Baobab, an enormous African tree, now known under the name of Adansonia. The volume for 1769 contains an interesting discussion by Adanson, upon the origin of the varieties of cultivated plants ; and in those for 1773 and 1779 will be found his valuable observations on gum-bearing trees. In the Trans¬ actions of 1767 he gave an account of the Oscillaioria Adansonii, which he considered a self-moving vegetable ; but which ought, according to some observations of M. Vaucher, to be ranked as a zoophyte. Besides these essays, Adanson contributed several valuable articles in natural history to the earlier part of the Supplement to the first Encyclopedic; and he is also supposed to have been the author of an essay on the Electricity of the Tourma¬ line (Paris 1757), which bears the name of the duke of Noya Caraffa.

ADDISON, Lancelot, son of Lancelot Addison, a clergyman, was born in the parish of Crosby-Ravensworth, in Westmoreland, in the year 1632. He was educated at Queen’s College, Oxford, and at the restoration of King Charles II. accepted of the chaplainship of the garrison of Dunkirk; but that fortress being delivered up to the French in 1662, he returned to England, and was soon after made chaplain to the garrison of Tangier, wdiere he continued seven years, and was greatly esteemed. In 1670 he re¬ turned to England, and was made chaplain in ordinary to the king; but his chaplainship of Tangier being taken from him on account of his absence, he found himself straitened in his circumstances, when he seasonably ob¬ tained the rectory of Milston in Wiltshire, worth about L.120 per annum. He afterwards became a prebendary of Sarum, took his degree of doctor of divinity at Ox¬ ford, and in 1683 was made dean of Lichfield, and the next year archdeacon of Coventry. His life was ex¬ emplary, his conversation pleasing and greatly instruc¬ tive, and his behaviour as a gentleman, a clergyman, and a neighbour, did honour to the place of his residence. He wrote, 1. A Short Narrative of the Revolutions of the Kingdoms of Fez and Morocco; 2. The present State of the Jews ; 3. A Discourse on Catechising; 4. A Modest Plea for the Clergy; 5. An Introduction to the Sacra¬ ment ; 6. The first State of Mahometism; and several other pieces. This worthy divine died on the 20th of April 1703, and left three sons ; Joseph, the subject of the next article; Gulston, who died while governor of Fort St George ; Lancelot, master of arts, and fellow of Magdalen College in Oxford; and one daughter, first married to Dr Sarte, prebendary of Westminster, and afterwards to Ad, Daniel Combes, Esq. Addison,the son of the preceding Dean Addison, was born at Milston, near Ambresbury, in Wiltshire, on the 11th of May 1672; and not being thought likely to live, was baptized the same day. He received the first rudiments of his education at the place of his nativity under the reverend Mr Naish, but was soon removed to Salisbury under the care of Mr Taylor, and from thence to the Charter-house, where his acquaintance with Sir Richard Steele commenced. About the age of 15, he was entered at Queen’s College, Oxford, where he applied very closely to the study of classical learning, in which he made a surprising proficiency. In the year 1687, Dr Lancaster, dean of Magdalen Col¬ lege, having by chance seen a Latin poem of Mr Addison’s, was so pleased with it, that he immediately got him elect¬ ed into that house, where he took his degrees of bachelor and master of arts. His Latin pieces, in the course of a few years, were exceedingly admired in both universi¬ ties ; nor were they less esteemed abroad, particularly by the celebrated Boileau, who is reported to have said, that he would not have written against Perrault had he before seen such excellent pieces by a modern hand. He published nothing in English before the 22d year of his age, when there appeared a short copy of verses written by him, and addressed to Mr Dryden, which procured him great reputation from the best judges. This was soon followed by a translation of the fourth Georgic of Virgil (omitting the story of Aristaeus), much commended by Mr Dryden. He wrote also the Essay on the Georgies prefixed to Mr Dryden’s transla¬ tion. There are several other pieces written by him about this time; amongst the rest, one dated the 3d of April 1694, addressed to H. S. that is, Dr Sacheverel, who be¬ came afterwards so famous, and with whom Mr Addison lived once in the greatest friendship; but their intimacy was some time after broken off, by their disagreement in political principles. In the year 1695 he wrote a poem to King William on one of his campaigns, addressed to Sir John Somers, lord-keeper of the great seal. This gentle¬ man received it with great pleasure, took the author into the number of his friends, and bestowed on him many marks of his favour. Mr Addison had been closely pressed while at the uni¬ versity to enter into holy orders, and had once resolved upon it; but his great modesty, his natural diffidence, and an uncommonly delicate sense of the importance of the sacred function, made him afterwards alter his resolution; and having expressed an inclination to travel, he was en¬ couraged thereto by his patron above mentioned, who by his interest procured him from the crown a pension of L.300 per annum to support him in his travels. He ac¬ cordingly made a tour to Italy in the year 1699; and in 1701 he wrote a poetical epistle from Italy to the earl of Halifax, which has been much esteemed both abroad and at home. It was translated into Italian verse by the abbot Antonio Maria Salvini, Greek professor at Florence. In the year 1705 he published an account of his travels, de¬ dicated to Lord Somers ; which, though at first but indif¬ ferently received, yet in a little time met with its deserv¬ ed applause. In the year 1702 he was about to return to England, when he received advice of his being appointed to attend Prince Eugene, who then commanded for the emperor in Italy; but the death of King William happening soon after, put an end to this affair, as well as his pension ; and he re¬ mained for a considerable time unemployed. But an un¬ expected incident at once raised him, and gave him an ADD :ison. opportunity of exerting his fine talents to advantage ; for, /"^in the year 1704*, the lord treasurer Godolphin happened to complain to Lord Halifax that the duke of Marl¬ borough’s victory at Blenheim had not been celebrated in verse in the manner it deserved; and intimated, that he would take it kindly if his lordship, who was the known patron of the poets, would name a gentleman capable of doing justice to so elevated a subject. Lord Halifax re¬ plied, somewhat hastily, that he did know such a person, but would not mention him; adding, that long had he seen with indignation men of no merit maintained in luxury at the public expense, whilst those of real worth and modesty were suffered to languish in obscurity. The treasurer answered very coolly, that he was sorry there should be occasion for such an observation, but that he would do his endeavour to wipe off such reproaches for the future; and he engaged his honour, that whoever might be namedby his lordship as a person capable of celebrating this victory, should meet with a suitable recompense. Lord Halifax thereupon named Mr Addison; insisting, however, that the treasurer himself should send to him ; which he promised. Accordingly he prevailed on Mr Boyle (after¬ wards Lord Carlton), then chancellor of the exchequer, to make the proposal to Mr Addison ; which he did in so polite a manner, that our author readily undertook the task. The lord treasurer had a sight of the piece when it was carried no further than the celebrated simile of the angel, and was so pleased with it, that he immediately appointed Mr Addison a commissioner of appeals, vacant by the promotion of Mr Locke, chosen one of the lords commissioners for trade. The Campaign is addressed to the duke of Marlborough : it gives a short view of the military transactions in 1704, and contains a noble descrip¬ tion of the two great actions at Schellemberg and Blen¬ heim. In 1705 he attended Lord Halifax to Hanover, and the ensuing year was appointed under secretary to Sir Charles Hedges, secretary of state, in which office he acquitted himself so well that the earl of Sunderland, who succeeded Sir Charles in December, continued Mr Addi¬ son in his employment. A taste for operas beginning at this time to prevail in England, and many persons having solicited Mr Addison to write one, he complied with their request, and composed his Rosamond. Tins, however, whether from the defect of the music, or from the prejudices in favour of the Italian taste, did not succeed upon the stage ; but the poetry of it has been, and always will be, justly admired. About this time Sir Richard Steele composed his comedy of the Tender Husband, to which Mr Addison wrote a prologue. Sir Richard surprised him with a dedication of this play, and acquainted the public that he was indebted to him for some of the most excellent strokes in the performance. -The marquis of Wharton, being appointed lord lieutenant of Ireland in 1709, took Mr Addison with him as his secretary. Her Majesty also made him keeper of the re¬ cords of Ireland, and as a further mark of her favour, con- siderably augmented the salary annexed to that place. Wlnlst he was in this kingdom, the Tatler was first publish¬ ed ; and he discovered his friend Sir Richard Steele to be the author, by an observation on Virgil, which he had communicated to him. He afterwards assisted consider- ? y 111 carrying on this paper, which the author acknow- ec ges. ^ Ihe latter being laid down, the Spectator vtas set on foot, and Mr Addison furnished great part of the m°st admired papers. The Spectator made its first ap¬ pearance in March 1711, and was brought to a conclusion in September 1712. His celebrated Cato appeared in 1713. He formed the aesign of a tragedy upon this subject when he was very VOL.

It was received with the most uncommon applause, having run 35 nights without interruption. The Whigs applaud¬ ed every line in which liberty was mentioned, as a satire on the lories; and the Tories echoed every clap, to show" that the satire was unfelt. When it was printed, notice was given that the queen would be pleased if it was dedi¬ cated to her; “ but as he had designed that compliment elsewhere, he found himself obliged,” says Tickell, “ by his duty on the one hand, and his honour on the other, to send it into the world without any dedication.” It was no less esteemed abroad, having been translated into trench, Italian, and German; and it was acted at Leghorn and several other places with vast applause. The Jesuits of St Omer made a Latin version of it, and the students acted it with great magnificence. About this time another paper called the Guardian was published by Steele, to which Addison was a principal contributor. It was a continuation of the Spectator, and was distinguished by the same elegance and the same variety; but, in consequence of Steele’s propensity to politics, was abruptly discontinued in order to write the Englishman. The papers of Addison are marked in the Spectator by one of the letters in the name of Clio, and in the Guardian by a Hand. Many of these papers were written with powers truly comic, with nice discrimination of characters, and accurate observation of natural or accidental devia¬ tions from propriety ; but it was not supposed that he had tried a comedy for the stage, till Steele, after his death, declared him the author of the Drummer. This, how¬ ever, he did not know to be true by any cogent testimony; for when Addison put the play into his hands, he only told him it was the work of a gentleman in the company: when it was received, as is confessed, with cold disapprobation, he was probably less willing to claim it. Tickell omitted it in his collection; but the testimony of Steele, and the total silence of any other claimant, has determined the public to assign it to Addison, and it is now printed with his other poetry. Steele carried the Drummer to the playhouse, and afterwards to the press, and sold the copy for 50 guineas. To Steele’s opinion may be added the proof supplied by the play itself, of which the characters are such as Addison would have delineated, and the ten¬ dency such as Addison would have promoted. It is said that Mr Addison intended to compose an English dictionary, upon the plan of the Italian Della Crusca ; but that upon the death of the queen, being ap¬ pointed secretary to the lords justices, he had not leisure to carry on such a work. When the earl of Sunderland was appointed lord-lieutenant of Ireland, Mr Addison was again made secretary for the affairs of that kingdom; and upon the earl’s being removed from the lieutenancy, he was chosen one of the lords of trade. Not long afterwards an attempt was made to revive the Spectator, at a time indeed by no means favourable to li¬ terature, when the accession of a new family to the throne filled the nation with anxiety, discord, and confusion; and either the turbulence of the times or the satiety of the readers put a stop to the publication, after an experiment of 80 numbers, which were afterwards collected into an eighth volume, perhaps more valuable than any of those that went before it: Addison produced more than a fourth part. T 146 ADDISON. Addison. In 1715 he began the Freeholder, a political paper, which was much admired, and proved of great use at that juncture. He published also, about this time, verses to Sir Godfrey Kneller upon the king’s picture, and some to the princess of Wales with the tragedy of Cato. Before the arrival of King George he was made secre¬ tary to the regency, and was required by his office to send notice to Hanover that the queen was dead, and that the throne was vacant. To do this would not have been dif¬ ficult to any man but Addison, who was so overwhelmed with the greatness of the event, and so distracted by choice of expression, that the lords, who could not wait for the niceties of criticism, called Mr Southwell, a clerk in the house, and ordered him to dispatch the message. Southwell readily told what was necessary, in the common style of business, and valued himself upon having done what was too hard for Addison. In 1716 he married the countess dowager of Warwick, whom he had solicited by a very long and anxious court¬ ship. He is said to have first known her by becoming tutor to her son. The marriage, if uncontradicted report can be credited, made no addition to his happiness. The year after, 1717, he rose to his highest elevation, being made secretary of state; but is represented as having proved unequal to the duties of his place. In the House of Commons he could not speak, and therefore was useless to the defence of the government. In the office he could not issue an order without losing time in quest of fine expressions. At last, finding by experience his own in Addison’s course of life before his marriage has been Ad ^ detailed by Pope. His chief companions were Steele, ^jvj Bugdell, Philips, Carey, Davenant, and Colonel Brett. With one or other of these he always breakfasted. He studied all morning; then dined at a tavern, and went afterwards to Button’s. From the coffee-house he went to the tavern, where he often sat late and drank too much wine. Dr Johnson justly observes, that Addison “ not only made the proper use of wit himself, but taught it to others; and from his time it has been generally subser¬ vient to the cause of reason and of truth. He has dissi¬ pated the prejudice that had long connected gaiety with vice, and easiness of manners with laxity of principles. He has restored virtue to its dignity, and taught inno¬ cence not to be ashamed. This is an elevation of literary character, above all Greek, above all Roman fame. No greater felicity can genius attain, than that of haying pu¬ rified intellectual pleasure, separated mirth from indecen¬ cy, and wit from licentiousness; of having taught a suc¬ cession of writers to bring elegance and gaiety to the aid of goodness; and, to use expressions yet more awful, of having turned many to righteousness!'—“ As a describer of life and manners,” says the same author, “ he must be allowed to stand perhaps the first of the first rank. His humour, which, as Steele observes, is peculiar to himself, is so happily diffused as to give the grace of novelty to domestic scenes and daily occurrences. He never out¬ steps the modesty of nature, nor raises merriment or wonder ability for public business, he^was forced to solicit his dis- by the violation of truth. His figures neither divert by mission, with a pension of L.1500 a year. Such was the distortion nor amaze by aggravation. He copies life with 1 Evidences of the Christian Religion. account of those who were inclined to detract from his abilities ; but by others his relinquishment was attributed to declining health, and the necessity of recess and quiet. In his retirement he applied himself to a religious work,1 which he had begun long before; part of which, scarce finished, has been printed in his works. He intended also to give an English paraphrase of some of David’s psalms; but his ailments increased, and cut short his designs. He had for some time been oppressed by an asthmatic disorder, which was now aggravated by a drop¬ sy, and he prepared to die conformably to his precepts and professions. He sent, as Pope relates, a message by the earl of Warwick to Mr Gay, desiring to see him. Gay, who had not visited him for some time before, obeyed the summons, and was received with great kindness. The purpose for which the interview had been solicited was then discovered: Addison told him that he had injured him, but that if he recovered he would recompense him. What the injury was he did not explain, nor did Gay ever know; but supposed that some preferment de¬ signed for him had by Addison’s intervention been with¬ held. Another death-bed interview, of a more solemn nature, is recorded. Lord Warwick was a young man of very irregular life, and perhaps of loose opinions : Addi¬ son, for whom he did not want respect, had very diligent¬ ly endeavoured to reclaim him; but his arguments and expostulations had no effect. One experiment, however, remained to be tried. When he found his life near its end, he directed the young lord to be called; and when he desired, with great tenderness, to hear his last in¬ junctions, told him, “ I have sent for you that you may see how a Christian can die.” What effect this awful scene had on the earl’s behaviour is not known: he died himself in a short time. Having given directions to Mr Tickell for the publication of his works, and dedicated them on his death-bed to his friend Mr Craggs, he died June 17. 1719, at Holland-house, leaving only one child, a daughter, by his marriage. so much fidelity, that he can hardly be said to invent; yet his exhibitions have an air so much original, that it is difficult to suppose them not merely the product of imagination. As a teacher of wisdom he may be confi¬ dently followed. His religion has nothing in it enthu¬ siastic or superstitious ; he appears neither weakly credu¬ lous nor wantonly sceptical; his morality is neither dan¬ gerously lax nor impracticably rigid. All the enchant¬ ment of fancy and all the cogency of argument are em¬ ployed to recommend to the reader his real interest, the care of pleasing the Author of his being. 'I ruth is shown sometimes as the phantom of a vision, sometimes appears half-veiled in an allegory; sometimes attracts regard in the robes of fancy, and sometimes steps forth in the con¬ fidence of reason. She wears a thousand dresses, and in all is pleasing. “ His prose is the model of the middle style; on grave subjects not formal, on light occasions not grovelling; pure without scrupulosity, and exact without apparent elaboration; always equable, and always easy, without glowing words or pointed sentences. W hoever wishes to attain an English style, familiar but not coarse, and ele¬ gant but not ostentatious, must give his days and nights to the volumes of Addison.” (Johnson’s Lives of the Poets!) Dr Johnson has related the following anecdote, which every admirer of Addison, every man of feeling, must be reluctant to believe. “ Steele,” says the doctor, “ whose imprudence of generosity or vanity of profusion kept him always incurably necessitous, upon some pressing exi¬ gence, in an evil hour, borrowed a hundred pounds of his friend, probably without much purpose of repayment; but Addison, who seems to have had other notions of a hundred pounds, grew impatient of delay, and reclaimed his loan by an execution. Steele felt, with great sensi¬ bility, the obduracy of hrs creditor; but with emotions of sorrow rather than of anger.” It is much to be wished, says Dr Kippis, that Dr Johnson had produced his autho- add ADD 14/ A lison. rity for thl-s narration. It is very possible that it may be L.y-x-^only a story the doctor had somewhere heard in conver¬ sation, and which is entirely groundless; “ and this I am the rather inclined to believe, as I have been assured, by one of the most respectable characters in the kingdom, that the fact hath no foundation in truth.” Mr Potter, in a late publication, hath informed us, that he is told by the best authority that the story is an absolute falsehood. Mr Tyers, in A Historical Essay on Mr Addison, print¬ ed, but not published, has mentioned some facts concern¬ ing him, with which we were not before acquainted. These are, that he was laid out for dead as soon as he was born ; that when he addressed his verses on the Eng¬ lish poets to Henry Sacheverel, he courted that gentle¬ man’s sister; that whenever Jacob Tonson came to him for the Spectator, Bayle’s French Historical and Critical Dictionary lay always open before him; that upon his return to England, after his travels, he discharged some old debts he had contracted at Oxford, with the genero¬ sity of good interest; that he was put into plentiful cir¬ cumstances by the death of a brother in the East Indies; that, having received encouragement from a married lady, of whom he had been formerly enamoured, he had the integrity to resist the temptation; that he refused a gra¬ tification of a three hundred pounds bank-note, and after¬ wards of a diamond-ring of the same value, from a Major Dunbar, whom he had endeavoured to serve in Ireland by his interest with Lord Sunderland; and that his daughter by Lady Warwick died unmarried, residing at Bilton near Rugby, and possessing an income of more than twelve hundred a year. The following letter, which probably relates to the case of Major Dunbar, reflects great honour on Mr Addison’s integrity. “ June 26. 1715. Sir,—I find there is a very strong opposition formed against you; but I shall wait on my lord-lieutenant this morning, and lay your case before him as advantageously as I can, if he is not engaged in other company. I am afraid what you say of his grace does not portend you any good. And now, Sir, believe me, when I assure you I never did, nor ever will, on any pretence whatsoever, take more than the stated and cus¬ tomary fees of my office. I might keep the contrary practice concealed from the world, were I capable of it, but I could not from myself; and I hope I shall always fear the reproaches of my own heart more than those of all mankind. In the mean time, if I can serve a gentle¬ man of merit, and such a character as you bear in the world, the satisfaction I meet with on such an occasion is always a sufficient, and the only reward to, Sir, your most obedient humble servant, J. Addison.” Ihe anecdote which follows was told by the late Dr Birch. Addison and Mr Temple Stanyan were very in¬ timate. In the familiar conversations which passed be¬ tween them, they were accustomed freely to dispute each other s opinions. Upon some occasion Mr Addison lent Stanyan five hundred pounds. After this Mr Stanyan behaved with a timid reserve, deference, and respect; not conversing with the same freedom as formerly, or canvassing his friend’s sentiments. This gave great un¬ easiness to Mr Addison. One day they happened to fall upon a subject, on which Mr Stanyan had always been used strenuously to oppose his opinion. But even upon ms occasion he gave way to what his friend advanced, wrthout interposing his own view of the matter. This hurt Mr Addison so much, that he said to Mr Stanyan, rp.r contradict me, or pay me the money.” \ ■ Eckell s edition of Mr Addison’s works, published in 4 vols. 4to, there are several pieces hitherto unmen- noned, viz. The Dissertation on Medals; The Present State of the War, and the Necessity of an Augmentation Addita- considered; The late Trial and Conviction of Count Ta- ment riff; The Whig Examiner. Five of these papers were at- . Ij tributed to Mr Addison, and they are the severest pieces, Ade ’ he ever wrote. He is said also to have been the author of a performance entitled Dissertatio de insignioribus Ro- manorum Poetis, and of a Discourse on Ancient and Mo¬ dern Learning. ADDITAMENT, something added to another. Thus physicians call the ingredients added to a medicine al¬ ready compounded, additaments. ADDITION, in Music, a dot marked on the right side of a note, signifying that it is to be sounded or lengthened half as much more as it would have been without such mark. Addition, in Law, is that name or title which is given to a man over and above his proper name and surname, to show of what estate, degree, or mystery he is; and of what town, village, or country. Additions of Estate or Quality are, Yeoman, Gen¬ tleman, Esquire, and such like. Additions of Degree are those we call names of dig¬ nity ; as Knight, Lord, Earl, Marquis, and Duke. Additions of Mystery are such as Scrivener, Painter, Mason, and the like. Additions of Place are, of Thorpe, of Dale, of Wood- stock. Where a man hath household in two places, he shall be said to dwell in both, so that his addition in either may suffice. By stat. 1 Hen. V. cap. 5. it was or¬ dained, that in such suits or actions where process of outlawry lies, such addition should be made to the name of the defendant, to show his estate, mystery, and place where he dwells ; and that the writs not having such ad¬ ditions should abate if the defendant take exception thereto, but not by the office of the court. The reason of this ordinance was, that one man might not be troubled by the outlawry of another ; but by reason of the certain addition, every person might bear his own burden. Additions, in Distilling, a name given to such things as are added to the wash or liquor while in a state of fermentation, in order to improve the vinosity of the spi¬ rit, procure a larger quantity of it, or give it a particular flavour. All things, of whatever kind, thus added in the time of fermentation, are called by those of the business who speak most intelligently, additions; but many confound them with things of a very different nature, under the name offerments. Additions, in Heraldry, some things added to a coat- of-arms, as marks of honour; and therefore directly oppo¬ site to abatements. Among additions we reckon Bor- dure, Quarter, Canton, Gyron, Pile, &c. ADDRESS, in a general sense, is used for skill and good management, and of late has been adopted from the French. It is used also in commerce, as synonjunous with direction to a person or place. The word is formed of the French verb adresser, to direct any thincr to a person. ADDUCENT Muscles, or Adductors, in Anatomy, are those muscles which pull one part of the body towards another. ADEB, in Commerce, the name of a large Egyptian weight, used principally for rice, and consisting of 210 okes, each of three rotolos, a weight of about two drams less than an English pound. But this is no certain weight, for at Rosetto the adeb is only 150 okes. ADEL, a kingdom on the eastern coast of Africa, which reaches as far as the Straits of Babelmandel, which unite the Red Sea to the sea of Arabia. This country produces corn, and feeds a great number of cattle. The 148 A D E A D E Adelfors inhabitants carry on a trade in gold, sdver, ivory, oil, I! frankincense, a sort of pepper, and other merchandises of Adelung.^ Arabia and the Indies. The king was formerly a vassal ' to the grand negus of Abyssinia ; but being Mahometans, and the Abyssinians a sort of Christians, they could not agree, and in 1535 came to an open rupture, when the Adelians threw off the yoke, seeking protection from the «rand signior. The principal places are Adela, seated in the centre of the country, and the town where the king resides* ADELFORS, a town in Sweden, in the province of Jbnkbping and district of Oestra, wherein are two gold mines worked but very sluggishly ; whilst the iron mines found there are very productive, and give employment both to the forges in making bar-iron, and to individuals as nail- makers. ADELME, or Aldhelm, son to Kenred, nephew to Ina, king of the West Saxons, was bishop of Sherburn in the time of the Heptarchy. He was the first Englishman who wrote in Latin, and the first wdio made any consider¬ able attempts in versification. He lived in great esteem till his death, which happened in 709. He was canonized, and many miracles were ascribed to him. He is mention¬ ed with great honour by Camden and Bale; and his life was written bv William of Malmesbury. ADELNAU, a circle in the province of Posen, in Prus¬ sia. It extends Over 346 square miles, or 324,440 acres, and contains, in four cities and 111 villages, 31, i 18 inhabitants. The river Proszna waters the east side, and the Ollabok the centre of the circle. There are several smaller rivers, and some lakes, the most considerable of which bears the name of the chief place near to which it is found. It is a * poor district, abounding with woods and game, and yield¬ ing fresh-water fish in plenty. It is very deficient in corn and cattle. The capital, of the same name, contains two Catholic and one Lutheran church, with 147 houses, and 1112 inhabitants. ADELPHIANI, in Church History, a sect of ancient heretics, who fasted always on Sundays. ADELSCALC, in ancient customs, denotes a servant of the king. The word is also written adelscalche, and adelscalus. It is compounded of the German culcl, oi edel, noble, and scale, servant. Among the Bavarians, adel- scalcs appear to have been the same with royal thanes among the Saxons, and those called ministri regis in an¬ cient charters. ADELSHEIM, a city in the bailiwick of Osterburken, and circle of the Maine and lauber, in the grand duchy of Baden. It belongs to a mediatised family of the same name, is walled, has two churches, 200 houses, and 1264 inhabitants. ADELSO, an island in Sweden, in the same lake in which the city of Stockholm is built, a little to the west of Munso, containing a parish of the same name. ADELUNG, John Christopher, a very eminent Ger¬ man grammarian, philologer, and general scholar, was born at Spantekow in Pomerania, on the 30th of August 1734. He acquired his elementary instruction at the public school of Anclam, and that of Closterbergen, near Magdeburg, and completed his academical education at the university of Halle. In the year 1759 he was ap¬ pointed professor at the gymnasium of Erfurt, but relin¬ quished this situation two years after, and went to reside in a private capacity at Leipsic, where he continued to de¬ vote himself for a long period to the cultivation of let¬ ters, and particularly to those extensive and laborious phi¬ lological researches which proved so useful to the lan¬ guage and literature of his native country. In 1787 he received the appointment of principal librarian to the elector of Saxony at Dresden, with the honorary title of Adi 1?, Aulic Counsellor. Here he continued to reside during^ \j the remainder of his useful life, discharging with dili¬ gence and integrity the duties of his situation, and prose¬ cuting his laborious studies to the last with indefatigable industry and unabated zeal. He died at Dresden on the 10th of September 1806, at the age of 72. The life of a mere scholar is generally destitute of in¬ terest ; and that of Adelung, which was spent entirely in literary seclusion, presents no variety of incident to the pen of the biographer. Of his private character and habits few memorials have been preserved; but in these few he is represented as a man of an amiable disposition. He was never married. His constitution, which was re¬ markably robust, rendered him capable of the most intense and unremitted application to study, insomuch that, down to the period of his death, he is said to have devoted four¬ teen hours of every day to literary labour. He was a lover of good cheer, and spared neither pains nor expense in procuring a variety of foreign wines, of which his cellar, which he facetiously denominated his Bibliotheca Selectis- sima, is said to have contained no less than forty different kinds. His manners were easy and affable, and the ha¬ bitual cheerfulness of his disposition rendered his society most acceptable to a numerous circle of friends. The works of Adelung are very voluminous; and there is not one of these, perhaps, which does not exhibit some proofs of the genius, industry, and erudition of the author. But although his pen was usefully employed upon a variety of subjects in different departments of literature and science, it is to his philological labours that he is principally indebted for his great reputation ; and no man ever devoted himself with more zeal and assiduity, or with greater success, to the improvement of his native lan¬ In a country which is subdivided into so many distinct sovereign states, possessing no common political centre, and no national institution whose authority could com¬ mand deference in matters of taste,—in a ^country w hose indigenous literature was but of recent growth, and where the dialect of the people was held in contempt at the several courts,—it was no easy task for a single writer to undertake to fix the standard of a language which had branched out into a variety of idioms, depending in a great measure upon principles altogether arbitrary. Ade¬ lung effected as much in this respect as could well be ac¬ complished by the persevering labours ot an individual. By means of his excellent grammars, dictionary, and va¬ rious works on German style, he contributed greatly to¬ wards rectifying the orthography, refining the idiom, and fixing the standard of his native tongue. Of all the dif¬ ferent dialects, he gave a decided preference to that ot the margraviate of Misnia, in Upper Saxony, and positive¬ ly rejected every thing that was contrary to the phrase¬ ology in use among the best society of that province, and in the writings of those authors whom it had produced. In adopting this narrow principle, he is generally thought to have been too fastidious. The dialect of Misnia was undoubtedly the richest, as it was the earliest cultivated, of any in Germany; but Adelung probably went too far in restraining the language within the limits of this single idiom, to the exclusion of others, from which it might have, and really has, acquired additional richness, flexibility) and force. His dictionary of the German language is generally al¬ lowed to be superior to our English dictionary by Dr Johnson. It is eminently so in its etymologies; and is, perhaps, upon the whole, the best work of the kind of which any nation can boast. Indeed, the patient spirit of A D E At lung, investigation which Adelung possessed in so remarkable a ^ degree, together with his intimate knowledge of the an¬ cient history and progressive revolutions of the different dialects from which the modern German is derived, ren¬ dered him peculiarly qualified for the successful perform¬ ance of the duties of a lexicographer. It would greatly exceed our limits, and lead us into far too wide a field, were we to attempt to present our read¬ ers with an analysis of the several productions of this voluminous author; but we should do injustice to his me¬ mory, were we to pass over in total silence his last very learned work, entitled Mithridates, or a General History of Languages, with the Lord's Prayer, as a specimen, in nearly Jive hundred, languages and dialects. The hint of this work appears to have been taken from a publication, with a similar title, published by the celebrated Conrad Gesner in 1555; but the plan of Adelung is much more extensive. Unfortunately, he did not live to finish what he had undertaken; but the work has been continued with much ability by that eminent philologer, Professor Vater, formerly of Halle, now of Kdnigsberg. The first volume, which contains the Asiatic languages, was pub¬ lished immediately after the death of Adelung; the second, which comprehends the European dialects, was published by Professor Vater in 1809; the first part of the third volume, which is almost entirely the work of the last-mentioned scholar, appeared in 1812. This third and last volume is to contain the languages of Africa and Ame¬ rica, and will be enriched with some very valuable mate¬ rials, communicated to the editor by Baron de Humboldt. Many of the works of Adelung were published anony¬ mously, but we believe the following list will be found to be complete and correct. 1.

In the above list there are more than one work which might probably be published with advantage in the English tongue. (k.) ADEMPTION, in the Civil Law, implies the revoca¬ tion of a grant, donation, or the like. ADEN, a city on the Arabian coast, to the east of the Straits of Babelmandel. It is situated in Lat. 12. 50. N. Long. 45. 10. E. According to the Arabians, it derives its name from Aden, the son of Saba, and grandson of Abra¬ ham. Be this as it may, it was once the most flourishing city of Arabia, though it now presents little more than a heap of ruins surrounded with miserable huts. But it is nevertheless a place of considerable consequence on that coast, from the superiority of its harbour, and its other advantages for trade. It is accessible at all times of the year; and from it a constant intercourse may be maintained with the coast of Africa. Coffee of the best quality, and all the other articles which enter into the commerce of the Red Sea, may be procured at this port. In particular, it is the chief mart for the gums brought over from the north-eastern districts of Africa; on which account this drug may be procured here at a cheaper rate than at Mocha. The English traders are much in favour at Aden. —See Salt’s Voyage to Abyssinia, and Milburn’s Oriental Commerce. ADENANTHERA, in Botany, Bastard Flower- fence. ADENAU, a circle in the department Rhine Moselle, in the Prussian province of the Lower Rhine. It extends over 172 square miles, or 110,080 acres, and contains 19,210 inhabitants, all Catholics, except 16 Jews and eight Protestants, in one city, three market towns, and 267 villages. It is watered by the river Ahr. It is generally a hilly and woody country, where little corn except oats grows, and where the chief subsistence is potatoes. Cattle and sheep are bred with tolerable success ; and potashes and charcoal are made from the forests. There is some little employment furnished by spinning and weaving both linens and wmollens on a small scale. The chief place of the same name contains 1250 inhabitants. ADENBURG, or Aldenburg, a town of Westphalia, and in the duchy of Berg, subject to the elector palatine. It is 12 miles north-east of Cologne, and 17 west of Bonn. Long. 7. 25. E. Lat. 51. 2. N.

ADEONA, in Mythology, the name of a goddess in¬ voked by the Romans when they set out upon a journey. ADEPHAGIA, in Mythology, the goddess of gluttony, to whom the Sicilians paid religious worship. ADEPS, in Anatomy, the fat found in the abdomen. It also signifies animal fat of any kind. ADEPTS, a term among alchemists for those who pre¬ tended to have found the panacea and philosopher’s stone. A D H Ad - ADIGE, a river in Italy, which, taking its rise south of the lake Glace, among the Alps, runs south by Trent, then east by Verona, in the territory of Venice, and falls into the Gulf of Venice north of the mouth of the Po. ADJOURNMENT, the putting off a court or other meeting till another day. There is a difference between the adjournment and the prorogatian of the parliament; the former not only being for a shorter time, but also done by the house itself; whereas the latter is an act of royal authority. ADIPOCIRE, derived from adeps, fat, and cera, wax, denotes a substance which has been lately examined by chemists. It is formed by a certain change which the soft parts of animal bodies undergo when kept for some ! time in running water, or when a great number of dead bodies are heaped together in the same place. Great i quantities of this substance were found on removing the I i animal matters from a burial-ground at Paris in the year | 1787. In this burial-ground 1200 or 1500 bodies were thrown together into the same pit, and being decomposed, were converted into this substance. It has some of the properties of wax or spermaceti. ADIPOSE, a term used by anatomists for any cell, membrane, &c. that is remarkable for its fatness. . ^ ADIRBEITSAN, in Geography, a province of Persia, in Asia, and part of the ancient Media. It is bounded on the north by the province of Schirvan, on the south by Irac-Agemi and Kurdistan, on the east by Ghilan and the Caspian Sea, and on the west by Turcomania. Long. 42. to 48. E.

The term is sometimes used for the air- shaft, which is a hole driven perpendicularly from the sur- j ! face of the earth into some part of the mine, to give en¬ trance to the air. ADJUDICATION, in Scotish Law, the name of that ac¬ tion by which a creditor attaches the heritable estate of i his debtor, or his debtor's heir, in order to appropriate it to himself either in payment or security of his debt; or | that action by which the holder of an heritable right, i labouring under any defect in point of form, may supply j i that defect. ADJUNCT, among philosophers, signifies something added to another, without being any necessary part of it- Thus, water absorbed by cloth or a sponge is an adjunct, | but no necessary part of either of these substances. Adjunct, in Metaphysics, some quality belonging to 1 either the body or mind, whether natural or acquired. Thus, thinking is an adjunct of the mind, and growth an adjunct of the body. Adjunct, in Music, a word which is employed to de¬ nominate the connection or relation between the principal ADM Aincts mode and the modes of its two-fifths, which, from the in¬ tervals that constitute the relation between them and it, At-inis- are called its adjuncts. lr or. Adjuncts, in Rhetoric and Grammar, signify certain ^ words or things added to others, to amplify or augment the force of the discourse. Adjunct Gods, or Adjuncts of the Gods, among the Romans, were a kind of inferior deities, added as assistants to the principal ones, to ease them in their functions. Thus, to Mars was adjoined Bellona and Nemesis ; to Nep¬ tune, Salacia; to Vulcan, the Cabiri; to the Good Genius, the Lares; to the Evil, the Lemures, &c. ADJUTANT, in the military art, is an officer whose business it is to assist the major. Each battalion of foot and regiment of horse has an adjutant, who receives the orders every night from the brigade-major ; which, after carrying them to the colonel, he delivers out to the serjeants. When detachments are to be made, he gives the number to be furnished by each company or troop, and assigns the hour and place of rendezvous. AoJUTANTs-general, among the Jesuits, a select num¬ ber of fathers, who resided with the general of the order, each of whom had a province or country assigned him, as England, Holland, &c.; and their business was to inform the father-general of state occurrences in such countries. To this end they had their correspondents delegated, emissaries, visitors, regents, provincials, &c. ADJUTORIUM, a term used by physicians for any medicine in a prescription but the capital one. ADLE Eggs, such as have not received an impregnation from the semen of the cock. ADLEGATION, a term formerly used in the public law of the German empire, to denote the right claimed by the states of the empire of adjoining plenipotentiaries, in public treaties and negotiations, to those of the emperor, for the transacting of matters which relate to the empire in general; in which sense adlegation differs from lega¬ tion, which is the right of sending ambassadors on a per¬ son’s own account. ADLOCUTION, Adlocutio, in Antiquity, is chiefly understood of speeches made by Roman generals to their armies, to encourage them before a battle. We frequent¬ ly find those adlocutions expressed on medals by the ab¬ breviature Adlocut. Coh.—The general is sometimes re¬ presented as seated on a tribunal, often on a bank or mound of turf, with the cohorts ranged orderly round him, in manipuli and turmce. The usual formula in adlocutions was, Forth esset ac fidus. ADMANUENSES, in ancient law-books, persons who swore by laying their hands on the book, as was the case with laymen. Clerks did not swear on the book, their word being reputed as their oath ; whence they were also denominated fide digni. ADMINICLE, a term used chiefly in old law-books to imply an aid, help, assistance, or support. The word is Latin, adminiculwn; and derived from adminicular, to prop or support. Adminicle, in Scotish Law, signifies any writing or deed referred to by a party, in an action of law, for proving his allegations. ADMINICULATOR, an ancient officer of the church, w lose business it was to attend to and defend the cause ° widows, orphans, and others destitute of help. ADIVIINis,j’R..A'ITC)N, in general, the government, di¬ rection, or management of affairs, and particularly the exercise of distributive justice. Among ecclesiastics, it is o ten used to express the giving or dispensing of the sacra¬ ments, &c. ° o r t, ADMINIS1R ATOR, in English Law, he to whom the vol. n. A D M 153 Admiral. ordinary commits the administration of the goods of a Adminis- person deceased, in default of an executor. If the admi- trator nistrator die, his executors are not administrators ; but the court is to grant a new administration. The origin of ad-, ministrators is derived from the civil law. Their establish-^ ment in England is owing to a statute made in the 31st year of Edward III. Till then, no office of this kind was known beside that of executor; in case of a want of which, the ordinary had the disposal of goods of persons intestate, &c. Administrator, in Scotish Law, a. person legally em¬ powered to act for another whom the law presumes in¬ capable of acting for himself. Administrator is sometimes used for the president of a province ; for a person appointed to receive, manage, and distribute the revenues of an hospital or religious house; for a prince who enjoys the revenues of a secu¬ larized bishop; and for the regent of a kingdom during the minority of a prince or a vacancy of the throne. ADMIRABILIS Sal, the same with Glauber’s Salt. ADMIRAL, a great officer or magistrate, who has the government of a navy, and the hearing of all maritime causes. Authors are divided with regard to the origin and de¬ nomination of this important officer. Sir Henry Spelman thinks that both the name and dignity were derived from the Saracens, and, by reason of the holy wars, brought amongst us ; for admiral, in the Arabian language, signi¬ fies a prince, or chief ruler, and was the ordinary title of the governors of cities, provinces, &c.; and therefore they called the commander of the navy by that name, as a name of dignity and honour. Ducange assures us that the Sicilians were the first, and the Genoese the next, who gave the denomination of admiral to the commanders of their naval armaments; and that they took it from the Saracen or Arabic emir, a general name for every com¬ manding officer. As for the exact time when the word was introduced among us, it is uncertain. Some think it was in the reign of Edward I. Sir Henry Spelman is of opinion that it was first used in the reign of Henry III. because neither the laws of Oleron, made in 1266, nor Bracton, who wrote about that time, make any mention of it. In the latter part of that reign, not only the historians, but the charters themselves, very frequently use the word admiral. Anciently there were generally three or four admirals appointed for the English seas, all of them holding the office durante heneplacito, and each of them having par¬ ticular limits under his charge and government; as admirals of the fleet of ships from the mouth of the Thames, northward, southward, or westward. Besides these, there were admirals of the Cinque Ports. We sometimes find that one person had been admiral of the fleets to the southward, northward, and westward; but the title of Admiralis Anglice was not frequent till the reign of Henry IV. when the king’s brother had that title given him, which in all commissions afterwards was granted to the succeeding admirals. It may be observed, that there was a title above that of admiral of England, which was, locum tenens regis super mare, the king’s lieutenant-general of the sea: this title we find mentioned in the reign of Richard II. Before the use of the word admiral was known, the title of custos maris was made use of. Of the rank of admiral there are three degrees; admiral, vice-admiral, rear-admiral. Each of these degrees consists of three divisions, which are distinguished by as mainy different colours or flags ; hence all admirals assume the common title offlag-officers, and take rank and command in the following order :— U 154 5 ADMIRAL. Admiral. Admirals of the Red, of the White, of the Blue Squad* rons, bearing their respective flags at the main-top-gallant- mast head; Vice-admirals of the Red, of the White, of the Blue Squadrons, bearing their respective flags at the fore-top-gallant-mast head; Rear-admirals of the Red, of the White, of the Blue Squadrons, bearing their re¬ spective flags at the mizen-top-gallant-mast head. It may be remarked, that for a century nearly we had no Admiral of the Red Squadron; that flag, according to a vulgar error, having been taken from us by the Dutch in one of those arduous struggles for naval superiority which that nation was once able to maintain against the naval power of England. But the fact is, the red flag was laid aside on the union of the two crowns or England and Scotland, when the Union flag was adopted in its place, and usually hoisted by the admiral commanding in chief. The red flag, however, has recently been revived, on an occasion worthy of the event; namely, on the pro¬ motion of naval officers which took place in November 1805, in consequence of the memorable victory off Tra¬ falgar. See Navy. Admiral of the Fleet is a mere honorary distinc¬ tion, which gives no command, but an increase of half¬ pay, his being three guineas a day, and that of an admi¬ ral two guineas. It is sometimes conferred, but not al¬ ways, on the senior admiral on the list of naval officers, being held at present by his royal highness the duke of Clarence. If the admiral of the fleet should happen to serve afloat, he is authorized to carry the union flag at the main-top-gallant-mast head; which was the case when the duke of Clarence escorted Louis XVIII. across the Channel to take possession of the throne of France. The comparative rank which flag-officers hold with offi¬ cers in the army has been settled as follows by his Ma¬ jesty’s order in council:— The admiral and commander-in-chief of the fleet has the rank of a field-marshal in the army; admirals with flags at the main take rank with generals of horse and foot; vice-admirals with lieutenant-generals; rear-admi¬ rals with major-generals; commodores with broad pendants with brigadier-generals. See Navy. Admiral, the Lord High, of England, an ancient officer of high rank in the state, in whom not only the go¬ vernment of the navy is vested, but who, long before any regular navy existed in England, presided over a sove¬ reign court, with authority to hear and determine all causes relating to the sea, and to take cognizance of all offences committed thereon. There can be little doubt of the Asiatic origin of the name given to this officer, which does not appear to have been known in the languages of Europe before the time of the holy wars. Amir, in Arabic, is a chief or com¬ mander of forces; it is the same word as the ameer of the peninsula of India (as ameer al omrah, the chief of lords or princes), and the emir of the Turks or Sa¬ racens, who had, and still have, their emir or ameer l dureea, commander of the sea; amir l asker dureea, com¬ mander of the naval armament. The incorporation of the article with the noun appears, we believe, for the first time in the Annals of Eutychius, patriarch of Alexandria, in the tenth century, who calls the Caliph Omar Amirol munumim, seu, Imperator fidelium. Spelman says, “ In regno Saracenorum quatuor praetores statuit, qui admiralli Yocabantur.” The d is evidently impertinent, and is omitted by the French, who say Amiral. The Spanish write Almirante; the Portuguese the same. Milton would seem to have been aware of the origin of the word, when he speaks of “ the mast of some great Ammiral.” It is obvious, then, that the supposed derivations of dkiwoog from the Greek, aumer from the French, and aen Adn mereal from the Saxon, are fanciful and unauthorized ety- ^ ) mologies. The period of time about which this officer first makes his appearance in the governments of European nations, corroborates the supposition of its having been adopted in imitation of the Mediterranean powers, at the return of the Christian heroes from the holy wars. According to Moreri, Florent de Varenne, in the year 1270, was the first admiral known in France ; but by the most approved writers of that nation, the title was unknown till, in 1284, Enguerand de Coussy was constituted Admiral. The first admiral by name that we know of in England was W. de Leybourne, who was appointed to that office by Edward I. in the year 1286, under the title of Admiral de la mer du Roy d'Angleterre. Mariana, in his History of Spain, says that Don Sancho, having resolved to make war on the barbarians (Moors), prepared a great fleet; and as the Genoese were at that time very powerful by sea, and experienced and dexterous sailors, he sent to Genoa to invite, with great offers, Benito Zacharias into his service; that he accepted those offers, and brought with him twelve ships; that the king named him his ad¬ miral {Almirante), and conferred on him the office for a limited time. This happened in the year 1284. Several Portuguese authors observe, that their office of Almirante was derived from the Genoese, who had it from the Sici¬ lians, and these from the Saracens; and it appears, from Souza’s Historia Genealogica da Caza Real, that, in 1322, Micer Manuel Pi^agow was invited from Genoa into Por¬ tugal, and appointed to the office of Almirante, with a sa¬ lary of three thousand pounds {livras) a year, and certain lands, &c. on condition that he should furnish, on his part, twenty men of Genoa, all experienced in sea affairs, and qualified to be alcaidis (captains) and arraises (masters) of ships : all of which terms, almirante, alcaidi, and arrais, are obviously of Arabic derivation. Edward 1. who began his reign in 1272, went to the Holy Land, and visited Sicily on his return. He must therefore have had an opportunity of informing himself concerning the military and naval science of the various countries bordering on the Mediterranean—an opportuni¬ ty which so able and warlike a prince would not neglect; but whether the title and office of admiral existed in England before his time, as some are inclined to think, or whether W. de Leybourne was first created to that office in 1286, as before mentioned, we believe there is no authentic record to enable us to decide. Supposing him, however, to be the first, Edward may either have adopted the office and title from the Genoese, or the Si¬ cilians, or the Spaniards, or the French; or even had it directly from the Saracens, against whom he had fought, and with whom he had afterwards much amicable inter* course. It would seem, however, that the office was in Edward's time merely honorary; for that monarch, in ! 1307, orders the lord mayor of London, at his peril and without delay, to provide a good ship, well equipped, to carry his pavilions and tents; and, in the same year, an- i other order is addressed to the Vicecomes Kantice, to pro¬ vide, for immediate passage across the seas, tot et tales pontes et claias as the constable of Dover Gastle should demand, without one word being mentioned of the admi¬ ral. (Rymer, vol. iii. p. 32.) From the 34th Edward II. we have a regular and un¬ interrupted succession of admirals. In that year he ap¬ pointed Edward Charles Admiral of the North, from the mouth of the river Thames northward, and Gervase Al¬ lard Admiral of the West, from the mouth of the Thames westward; and these two admirals of the north and the admiral. Adirai- west were continued down to the 34th Edward III., when V^ ^^John de Beauchamp, lord warden of the Cinque Ports, constable of the Tower of London, and of the Castle of Dover, was constituted High Admiral of England; but nine years afterwards the office was again divided* into north and west, and so continued until the 10th Richard II., when Richard, son of Alain earl of Arundel, was ap¬ pointed Admiral of England. Two years after this it was again divided as before; and in the 15th year of the same reign, Edward earl of Rutland and Cork, afterwards duke of Albemarle, was constituted High Admiral of the North and West; and after him the marquis of Dorset, and earl of Somerset, son of John of Gaunt, duke of Lancas¬ ter; then Percy earl of Winchester next succeeded to the same title, which once more was dropped in the 2d of Henry IV. and divided as before. But in the 6th of the same reign the office of Admiral of England became permanently vested in one person. In the 14th Henry VI. John Holland duke of Exeter was created -A.dmiral of England, Ireland, and Aquitaine for life; and in the third year of Edward VI. John Dudley earl of Warwick was constituted High Admiral of England, Ireland, Wales, Calais, Boulogne, the marches of the same, Normandy,’ Gascony, and Aquitaine, also Captain-general of the navy and seas of the king, &c. In the 27th Elizabeth, Charles Lord Howard had all the aforesaid titles, with the addi¬ tion of Captain-general of the navy and seas of the said kingdoms. On the 20th November 1632, the office of high admi¬ ral was for the first time put in commission, all the great officers of state being the commissioners. During the Commonwealth, a committee of parliament managed the affairs of the admiralty. At the Restoration, in 1660, his royal highness James duke of York was constituted Lord High Admiral of England. The commission was revoked on the 22d May 1684, and King Charles II. held t ic admiralty in his own hands, and managed it by the great officers of his privy council until his death. He took this occasion of reserving for his own use all the droits and perquisites claimed by the lord high admi- TS: j ^ .James IL declared himself in council Lord High Admiral and Lord General; and he managed the affairs of the admiralty and navy by Mr Secretary Pepys ah the time of his reign. In the 1st William and Mary, the admiralty was again put in commission. In the 6th Anne (1/07), his royal highness George prince of Den¬ mark was appointed High Admiral of Great Britain (in consequence of the union of the two crowns), with a ta ass}st J"11; and at his death the queen acted 1 Jje.office by .Mr Burchett. On the 29th November «, it was again put in commission, or rather, the earl ol Pembroke was constituted High Admiral, with a coun- i to assist him; since which time the office of lord ugh admiral continued to be executed by lords com¬ missioners of the admiralty, until the 2d of May 1827 SJ1* ro/al highness the duke of Clarence was ap- P nted Lord High Admiral, with a council of four mem- ers to assist him ; in which office he continued to act, to mvn grCat sat,lsfactlon of the navy at large, until, at his h s h;!?Uem ’ 16 Wat Perrnitted by his Majesty to resign °n the 19th September 1828, when it was a^ain put in commission. Geo^e of Denmark, when lord high admiral, nrofii? surrendered, by a formal instrument, all the rights, ino- and advantages whatsoever, appertain- Se the benefitW use of the public, with of in sn?h n °f t le ST ofL-2500 a year, to be disposed Maiestv manner, and for such particular uses, as her fJ y, under her sign manual,, should direct; the salary 155 of the lord high admiral, which had hitherto hopn a a • i ™rivy JeT^LTCIOoV™ n°WJXhd’ by Warrant p ivy seal, at D./000 a year; which sum, by 1st George . was divided equally among seven commissioners, and continued to be so down to the present time, the part of the commissioner who stood first in the patent havino- however, been made up from other funds to L.SOOO^a year, and, m the year 1806, further increased by Lord Mowick, then first lord commissioner, to L.5000 a year, bince the surrender above mentioned, all the droits of ad'- miralty, as they are called, with all the fees, emoluments, perquisites, &c. whatsoever, have been taken from the admiral, and applied to public purposes. Ihese droits and perquisites are by no means incon¬ siderable. As enumerated in the patent, they consist of notson, jetson, lagon, treasure, deodands, derelicts, found within his jurisdiction; all goods picked up at sea; all fines, forfeitures, ransoms, recognizances, and pecuniary punishments; all sturgeons, whales, porpusses, dolphins, rigs, and grampusses, and all such large fishes; all ships and goods of the enemy coining into any creek, road, or port, by stress of weather, mistake, or ignorance of the war; all ships seized at sea, salvage, &c. together with his shares of prizes; which shares were afterwards called tenths, in imitation probably of the French, who o-ave their admiral, for supporting the dignity of his office, son droit de dixieme. All prizes are now wholly given up by the crown to the captors, and such share of the .droits as trom circumstances may be thought proper. The lord ugh admiral also claimed, and enjoyed as his due, the cast ships; and the subordinate officers of the navy as their perquisites, all other decayed and unserviceable stores. Though by act of 2d William and Mary the lords commissioners of the admiralty are vested with all and singular authorities, jurisdictions, and powers, which have been and are vested, settled, and placed in the lord high admiral of England for the time being, to all in¬ tents and purposes, as if the said commissioners were m admiral of England; yet there is this remark¬ able difference m the two patents by which they are con¬ stituted, that the patent of the lord high admiral men¬ tions very little of the military part of his office, but chief¬ ly details his judicial duties as a magistrate; whilst, on the contrary, the patent to the lords commissioners of the admiralty is very particular in directing them to go¬ vern the. affairs of the navy, and is almost wholly silent as to their judicial powers. These powers, as set forth in the patent to the earl of 1 embroke in 1/01, are, the power to act by deputy; to take cognizance of all causes, civiLand maritime, within Ins jurisdiction; to arrest goods anti persons ; to preserve public streams, ports, rivers, fresh waters, and creeks whatsoever, within his jurisdiction, as well for the preser¬ vation of the ships, as of the fishes; to reform too straight nets, and unlawful engines, and punish offenders; to arrest ships, mariners, pilots, masters, gunners, bombardiers, and any other persons whatsoever, able and fit for the service of the ships, as often as occasion shall require, and where¬ soever they shall be met with; to appoint vice-admirals judges, and other officers, durante beneplacito ; to remove, suspend, of expel them, and put others in their places, as he shall see occasion; to take cognizance of civil and maritime laws, and of death, murder, and maim. It was by no means necessary that the lord high ad¬ miral should be a professional man. Henry VIII. made his natural son, the duke of Richmond, lord high ad¬ miral of England, when he was but six years old. When the high admiral, however, went to sea in person, he had 156 ADM Admiral usually a commission under the great seal, appointing him ]l Admiral and Captain-general of the fleet, sometimes with Admiralty. p0wers t0 confer knighthood, and generally to punish with life and limb. Such a commission was granted by Henry VIII. to Sir Edward Howard, who executed indenture with the king to furnish 3000 men, 18 captains, 1750 soldiers, 1232 mariners and gunners; the pay of himself to be 10s. a day, of a captain Is. 6d., of the rest 5s. as wages, and 5s. for victuals each man, for twenty-eight days, together with certain dead shares. It appears, from Mr Pepys’s Naval Collections, that the lord high admiral did anciently wear, on solemn occasions, a gold whistle, set with precious stones, hanging at the end of a gold chain. The whistle, it would seem, has long since descended to the boatswain and his mates, (m.) Admiral, Lord High, of Scotland, one of the great officers of the crown, and supreme judge in all maritime cases within that part of Britain. Admiral is also an appellation given to the most con¬ siderable ship of a fleet of merchantmen, or of the vessels employed in the cod fishery of Newfoundland. This last has the privilege of choosing what place he pleases on the shore to dry his fish; gives proper orders, and appoints the fishing places to those who come after him; and as long as the fishing season continues, he carries a flag on his main-mast. Admiral, in Conchology, the English name of a species of the voluta, a shell-fish belonging to the order of vermes testacea. ADMIRALTY, High Court of. This is a court of law, in which the authority of the lord high admiral is exercised, in \\\s> judicial capacity, and wherein all causes are determined appertaining to the sea, and all offences tried that are committed thereon. Very little has been left on record of the ancient prerogative of the admirals of England. For some time after the first institution of the office, they judged all matters relating to merchants and mariners, which happened on the main sea, in a sum¬ mary way, according to the laws of Oleron, promulgated by Richard I. These laws, which were little more than a transcript of the Rhodian laws, became the universally received customs of the western part of the world. “ All the sea-faring nations,” says Sir Leoline Jenkins, “ soon after their promulgation, received and entertained these laws from the English, by way of deference to the sove¬ reignty of our kings in the British ocean, and to the judg¬ ment of our countrymen in sea affairs.” In the patents granted to the early admirals between the latter end of the reigfr of Henry III. and until the close of that of Edward III. no mention is made of marine perquisites or of civil power, nor does it appear that the admirals enjoyed either; but after the death of the lat¬ ter, new and extraordinary powers were granted to them, and it would appear that they usurped others. The pre¬ amble to the statute of 13th Richard II. sets forth, that “ forasmuch as a great and common clamour and com¬ plaint hath been oftentimes made before this time, and yet is, for that the admirals and their deputies hold their sessions within divers places of this realm, accroaching to them greater authority than belongeth to their office, in prejudice of our lord the king, and in destruction and im¬ poverishing of the common peopleand it is therefore directed that the admirals and their deputies shall not meddle from henceforth of any thing done within the realm, but only of a thing done upon the sea. And two years afterwards, in consequence, as stated in the preamble of the statute, “ of the great and grievous complaint of all the commons,” it was ordained that the admiral’s court should have no cognizance of any contracts, pleas, or quar- ADM rels, or of any thing done or arising within the bodies ofAdm counties, whether by land or by water, nor of wreck ofv- the sea; but that the admiral should have cognizance of the death of a man, and of maihern done in great ships beino- and hovering in the main stream of great rivers, yet only'beneath the bridges of the same rivers nigh the sea. Ho may also arrest ships in the great floats for the great voyages of the king and of the realm, and have jurisdic¬ tion over the said floats, but during the said voyages only. But if the admiral or his lieutenant exceed that jurisdic¬ tion, then, by 2d Henry IV., the statute of 13th Richard II. and common law may be holden against them ; and if a man pursues wrongfully in the admiralty court, his ad¬ versary may recover double damages at common law, and the pursuant, if attainted, shall incur the penalty of L.10 to the king. The place which, according to Spelman, is absolutely subject to the jurisdiction of the admiral, is the sea; which, however, comprehends public rivers, fresh waters, creeks, and all places whatsoever, within the ebbing and flowing of the sea, at the highest water, the shores or banks adjoining, from all the first bridges to the seaward; and in these, he observes, the admiralty hath full juris¬ diction in all causes, criminal and civil, except treasons and the right of wreck. Lord Coke observes, that “ be¬ tween the high water mark and the low water mark, the admiral hath jurisdiction super aquam, when the sea is full, and as long as it flows, though the land be infra cor¬ pus comitatus at the reflow, so as of one place there is divi- sum imperium at several times.” But though the statute restraineth the lord high ad¬ miral, that he shall not hold plea of a thing rising in the body of a county, he is not restrained from making exe¬ cution upon the land, but is empowered to take either body or goods upon the land; otherwise his jurisdiction would often prove a dead letter. He also can and does hold his court in the body of a county. So, likewise, the civil power may apprehend and try persons who may have been guilty of offences cognizable at common law, though committed in the fleet, in any port or harbour of Great Britain, or at sea, provided such persons have not already been tried for such offences, either by court-martial or in the admiralty court; and in all ports, harbours, creeks, &c. lying in any county, the high admiral and the sheriff, or coroner, as the case may be, have concurrent jurisdic¬ tion. The Lord High Admiral is assisted in his judicial functions by the following principal officers:—1. The Vice-admiral; 2. the Judge; 3. the Registrar; 4. the Marshal; 5. Advocate-general; 6. Procurator-general; 7. Counsellor; 8. Solicitor. 1. The Vice-admiral. This officer is the admiral’s de¬ puty or lieutenant, mentioned in the statutes of 13th and 15th Richard II., and was the person, most probably, who presided in the court. At present the office of vice-ad¬ miral of England is a perfect sinecure, generally conferred on some naval officer of high rank and distinguished cha¬ racter in the service, having a salary attached to it in ad¬ dition to his half-pay of L.469. 5s. 8d. per annum, lhat of rear-admiral of England is the same, and the salary in addition to his half-pay is L.370. 4s. 3d. per annum. Each county of England has its vice-admiral, which is little more than an honorary distinction, though the patent gives to him all the powers vested in the admiral himself. Similar powers were also granted to the judges of the ad¬ miralty county-courts; but this was found so inconveni¬ ent and prejudicial to those who had suits to commence or defend before them, that the duke of York, when lord high admiral, in 1663, caused instructions to be drawn ADMIRALTY. 157 Adn alty.up in order to ascertain to each his province, whereby goods that are or shall be taken; and to hear and deter-Admiralty v^.-Othe whole judicial power remained with the judge, and the mine according to the course of the admiralty, or the law ^^v-v^ upholding of the rights of the admiral, and levying and of nations; and a warrant issues to the judge of the ad- receiving the perquisites, &c. appertained to the vice-ad- miralty accordingly. miral. _ _ The admiralty court being in this respect a court in Each of the four provinces of Ireland has its vice-ad- which foreigners of all nations may become suitors an miral.

They are opposed to Jehovists ; of whom the principal are Drusius, Capellus, Buxtorf, Alting, and Reland, who has published a collection of their writings on this subject. ADOPTIANI, in Church History, a sect of ancient he¬ retics, followers of Felix of Urgel and Elipand of Toledo, who, towards the end of the eighth century, advanced the notion that Jesus Christ in his human nature is the Son of God, not by nature, but by adoption. . ADOPTION, an act by which any one takes another into his family, owns him for his son, and appoints him for his heir. The custom of adoption was very common among the ancient Greeks and Romans; yet it was not practised but for certain causes expressed in the laws, and with certain formalities usual in such cases. It was a sort of imitation of nature, intended for the comfort of those who had no children: wherefore, he that was to adopt was to have no children of his own, and to be past the age of getting any; nor were eunuchs allowed to adopt, as being under an actual impotency of begetting children : neither was it lawful for a young man to adopt an elder, because that would have been contrary to the order of nature; nay, it was even required that the person who adopted should be eighteen years older than his adopted son, that there might at least appear a probability of his being the natural father. Among the Greeks it was called u/onjs, filiation. It was allowed to such as had no issue of their own, ex¬ cepting those who were not xuwo/ saurwv, their own masters, e. g. slaves, women, madmen, infants, or persons under twenty years of age; who being incapable of making wills, or managing their own estates, were not allowed to adopt heirs to them. Foreigners being incapable of in¬ heriting at Athens, if any such were adopted, it was ne¬ cessary first to make them free of the city. The cere¬ mony of adoption being over, the adopted had his name enrolled in the tribe and ward of his new father; for which entry a peculiar time was allotted, viz. the festival SagyriAia. To prevent rash and inconsiderate adoptions, the Lacedemonians had a law, that adoptions should be transacted, or at least confirmed, in the presence of their ADO kings. The children adopted were invested with all the Adop privileges, and obliged to perform all the duties, of natural'^ children; and being thus provided for in another family, ceased to have any claim of inheritance or kindred in the family which they had left, unless they first renounced their adoption, which by the laws of Solon they were not allowed to do, unless they had first begotten children to bear the name of the person who had adopted them; thus providing against the ruin of the families, which would otherwise have been extinguished by the desertion of those who had been adopted to preserve them. If the children adopted happened to die without children, the inheritance could not be alienated from the family into which they had been adopted, but returned to the rela¬ tions of the adopter. It should seem that, by the Athe¬ nian law, a person, after having adopted another, was not allowed to marry without permission from the magi¬ strate ; and there are instances of persons who, being ill used by their adoptive children, petitioned for such leave. However this may be, it is certain that some men married after they had adopted sons ; in which case, if they begat legitimate children, their estates were equally shared be¬ tween the begotten and the adopted. The Romans had two forms of adoption; the one before the pretor, the other at an assembly of the people, in the times of the commonwealth, and afterwards by a re¬ script from the emperor. In the former, the natural father addressed himself to the pretor, declaring that he eman¬ cipated his son, resigned all his authority over him, and consented that he should be translated into the family of the adopter. The latter was practised where the party to be adopted was already free ; and this was called adrogation. The person adopted changed all his names, assuming the prename, name, and surname, of the person who adopted him. Besides the formalities prescribed by the Roman law, various other methods have taken place, which have given denominations to different species of adoption among the Gothic nations, in different ages. Thus, Adoption by Arms was when a prince made a present of arms to a person, in consideration of his merit and va¬ lour. The obligation here laid on the adoptive son was to protect and defend the father from injuries, affronts, &c. And hence, according to Selden, the ceremony of dubbing knights took its origin as well as name. Adoption by Baptism is that spiritual affinity which is contracted by godfathers and godchildren in the cere¬ mony of baptism. This kind of adoption was introduced into the Greek church, and came afterwards into use among the ancient Franks, as appears by the capitulars of Charlemagne. Adoption by Hair was performed by cutting off the hair of a person, and giving it to the adoptive father. It was thus that Pope John VIII. adopted Boson, king of Arles, which perhaps is the only instance in history of adoption in the order of the ecclesiastics; a law that professes to imitate nature, not daring to give children to those in whom it would be thought a crime to beget any. Adoption by Matrimony is the taking of the children of a wife or husband by a former marriage into the condi¬ tion of proper or natural children, and admitting them to inherit on the same footing with those of the present marriage. Adoption by Testament, that performed by appointing a person heir by will, on condition of his assuming the name, arms, &c. of the adopter; of which kind we meet with several instances in the Roman history. Among the Turks, the ceremony of adoption is performed by oblig¬ ing the person adopted to pass through the shirt of the T ADO i0] ye adopter. Hence, among that people, to adopt is ex¬ pressed by the phrase, to draw another through my shirt. ,rion.jt is said that something like this has also been ob- served among the Hebrews, where the prophet Elijah adopted Elisha for his son and successor, and communi¬ cated to him the gift of prophecy, by letting fall his cloak or mantle on him. But adoption, properly so called, does not appear to have been practised among the ancient Jews. Moses says nothing of it in his laws ; and Jacob’s adoption of his two grandsons, Ephraim and Manasseh, is not so properly an adoption as a kind of substitution, whereby those two sons of Joseph were allotted an equal portion in Israel with his own sons. ADOPTIVE denotes a person or thing adopted by another. Adoptive children, among the Romans, were on the same footing with natural ones, and accordingly were either to be instituted heirs or expressly disinherited, otherwise the testament was null. The emperor Adrian preferred adoptive children to natural ones; because we choose the former, but are obliged to take the latter at random.—M. Menage has published a book of eloges or verses addressed to him, which he calls Liber Adoptions, an adoptive book, and adds it to his other works. Hein- sius, and Furstemberg of Munster, have likewise publish¬ ed adoptive books.—In ecclesiastical writers we find adop¬ tive women or sisters (adoptivce ftemince or sorores) used for those handmaids of the ancient clergy, otherwise call¬ ed sub-introductce. Adoptive Arms are those which a person enjoys by the gift or concession of another, and to which he was not otherwise entitled. They stand contradistinguished from arms of alliance.—We sometimes meet with adoptive heir by way of opposition to natural heir, and adoptive gods by way of contradistinction to domestic ones. The Romans, notwithstanding the number of their domestic, had their adoptive gods, taken chiefly from the Egyp¬ tians : such were Isis, Osiris, Anubis, Apis, Harpocrates, and Canopus. ADORATION, the act of rendering divine honours, or of addressing a being, as supposing it a god. The word is compounded of ad, to, and os, oris, mouth; and lite- rally signifies to apply the hand to the mouth; manum ad os admovere, to kiss the hand; this being in the eastern countries one of the great marks of respect and submission.—The Romans practised adoration at sacri¬ fices and other solemnities ; in passing by temples, altars, groves, &c.; at the sight of statues, images, or the like, whether of stone or wood, wherein any thing of divinity was supposed to reside. Usually there were images of the gods placed at the gates of cities, for those who went in or out to pay their respects to. The ceremony of ado¬ ration among the ancient Romans was thus:—The devotee, having his head covered, applied his right hand to his lips, the fore finger resting on his thumb, which was erect, and thus bowing his head, turned himself round from left to right. The kiss thus given was called osculum labratum ; tor ordinarily they were afraid to touch the images of their gods themselves with their profane lips. Sometimes, owever, they would kiss their feet, or even knees, it being held an incivility to touch their mouths; so that the uttair passed at some distance. Saturn, however, and ercules were adored with the head bare; whence the vvors up of the last was called institutum peregrinum, and Tl , (xjGcanicus, as departing from the customary Roman method, which was to sacrifice and adore with the face veiled, and the clothes drawn up to the ears, to prevent any interruption in the ceremony by the sight of un- uc y objects. The Jewish manner of adoration was by prostration, bowing, and kneeling. The Christians adopt- VOL. II. r ADO ed the Grecian rather than the Roman method, and ador¬ ed always uncovered. The ordinary posture of the ancient Christians was kneeling, but on Sundays standing; and they had a peculiar regard to the east, to which point they ordinarily directed their prayers. J Adoration is also used for certain extraordinary civil honours or respects which resemble those paid to the Deity, yet are given to men. The Persian manner of adoration, introduced by Cyrus, was by bending the knee and falling on the face at the’ piinces feet, striking the earth with the forehead, and kissing the ground. This ceremony, which the Greeks called ‘x^oer.vmv, Conon refused to perform to Artaxerxes, and Calisthenes to Alexander the Great, as reputing it impious and unlawful. The adoration performed to the Roman and Grecian emperors consisted in bowing or kneeling at the prince’s feet, laying hold of his purple robe, and presently with¬ drawing the hand and clapping it to the lips. Some at¬ tribute the origin of this practice to Constantius. It was only persons of some rank or dignity that were entitled to the honour. Bare kneeling before the emperor to deliver a petition was also called adoration. , The practice of adoration may be said to be still sub¬ sisting in England, in the ceremony of kissing the king’s or queen’s hand, and in serving them at table, both being performed kneeling. Adoration is also used among Roman writers for a high species of applause given to persons who had spoken or performed well in public. See Acclamation. We meet with adoration paid to orators, actors, musicians, &c. The method of expressing it was, by rising, putting both hands to their mouth, and then returning them towards the person intended to be honoured. Adoration is also used in the court of Rome for the ceremony of kissing the popes feet. It is said of Dioclesian, that he had gems fastened to his shoes, that divine ho¬ nours^ might be more willingly paid him, by kissing his feet. The like usage was afterwards adopted by the popes, and is observed to this day. These prelates, finding a vehement disposition in the people to fall down before them and kiss their feet, procured crucifixes to be fasten¬ ed on their slippers; by which stratagem the adoration intended for the pope’s person is supposed to be trans¬ ferred to Christ. Adoration is also used for a method of electing a pope. The election of popes is performed two ways; by adora¬ tion and by scrutiny. In election by adoration, the cardi¬ nals rush hastily, as if agitated by some spirit, to the ado¬ ration of some one among them, to proclaim him pope. When the election is carried by scrutiny, they do not adore the new pope till he is placed on the altar. Barbarous AdorAtion is a term used, in the laws of King Canute, for that performed after the manner of the heathens, who adored idols. The Romish church is charged with the adoration of saints, martyrs, images, crucifixes, relics, the virgin, and the host; all which by Protestants are generally aggravated into idolatry, on a supposition that the honour thus paid to them is absolute and supreme, called by way of distinction Latria, which is due only to God. The Roman Catholics, on the con¬ trary, explain them as only a relative or subordinate wor¬ ship, called Dulia and Hyperdulia, which terminates ulti¬ mately in God alone. But may not the same be said of the idol worship of the heathens ? The Phoenicians adored the winds, on account of the terrible effects produced by them : the same was adopted by most of the other nations, Persians, Greeks, Romans, &c. The Persians chiefly paid their adorations to the sun and fire; some say also to 161 Adoration. 162 ADR Adorea rivers, the wind, &c. The motive of adoring the sun was II the benefits they received from that glorious luminary, which of all creatures has doubtless the best pretensions to such homage. ADOREA, in Roman Antiquity, a word used in dif¬ ferent senses : sometimes for all manner of grain ; some¬ times for a kind of cakes made of fine flour, and offered in sacrifice ; and, finally, for a dole or distribution of corn, as a reward for some service ; whence by metonymy it is put for praise or rewards in general. ADOSCULATION, a term used by Dr Grew to imply a kind of impregnation without intromission ; and in this manner he supposes the impregnation of plants is effected, by the falling of the farina fbecundans on the pistil. ADOSSEE, in Heraldry, signifies two figures or bear¬ ings being placed back to back. ADOUR, the name of a river of France, which rises in the mountains of Bigorre, in the department of the Upper Pyrenees, and running north by Tarbes through Gascony, afterwards turns east, and passing by Dax, falls into the Bay of Biscay below Bayonne. ADOWA, the capital of Tigre in Abyssinia, is situated on the declivity of a hill, on the west side of a small plain, which is surrounded on every side by mountains. The name, signifying -pass or passage, is characteristic of its si¬ tuation ; for the only .road from the Red Sea to Gondar passes by Adowa. The town consists of 300 houses, is the residence of the governor, and has a manufactory of coarse cotton cloth, which circulates in Abyssinia as the medium of exchange in place of money. Long. 38. 50. E. Lat. 14. 7. N. ADOXA, in Botany, Tuberous Moschatel, Hol¬ low-root, or Inglorious. ADRA, a seaport town of the province of Granada, in Spain, 47 miles south-east of Granada.

ADRAMMELECH, one of the gods of the inhabitants of Sepharvaim, who were settled in the country of Sama¬ ria in the room of those Israelites who were carried be¬ yond the Euphrates. The Sepharvaites made their chil¬ dren pass through the fire in honour of this idol and an¬ other called Anammelech. It is supposed that Adramme- lech meant the sun, and Anammelech the moon : the first signifies the magnificent king, the second the gentle king. ADRAMYTTIUM, in Ancient Geography, now Adra- miti, a town of Mysia, at the foot of Mount Ida, an Athe¬ nian colony, with a harbour and dock. ADRASTEA, in Mythology, was the daughter of Ju¬ piter and Necessity, and, according to Plutarch, the only fury who executed the vengeance of the gods. The name is derived from King Adrastus, who first erected a temple to that deity. Adrastea Certamina, in Antiquity, a kind of Pythian games instituted by Adrastus, king of Argos, in the year of the world 2700, in honour of Apollo, at Sicyon. These are to be distinguished from the Pythian games celebrat¬ ed at Delphi. ADRASTUS, in Ancient History, king of Argos, son of Talaus and Lysianassa, daughter of Polybius, king of Si¬ cyon, acquired great honour in the famous war of Thebes, in support of Polynices his son-in-law, who had been ex¬ cluded the sovereignty of Thebes by Eteocles his brother, notwithstanding their reciprocal agreement. Adrastus, followed by Polynices, and Tydeus his other son-in-law, by Capaneus and Hippomedon his sister’s sons, by An?- phiaraus his brother-in-laAv, and by Parthenopmus, marched against the city of Thebes; and this is the expedition of ADR the Seven Worthies, which the poets have so often sung. Ad,, They all lost their lives in this war except Adrastus, who was saved by his horse called Avion. This war was re- t vived ten years after by the sons of those deceased war-^^ riors, which was called the war of the Epigones, and end¬ ed with the taking of Thebes. None of them lost their lives except iEgialeus, son of Adrastus; which afflicted him so much that he died of grief in Megara, as he was leading back his victorious army. ADRAZZO, or Ajaccio, the same with Adjazzo. ADRIA, a city of Italy, in the Austria-Venetian pro¬ vince of Bovigio. It is a city of high antiquity, and gave its name to the sea on whose shores it is built. From its situation on a peninsula formed by the rivers Po and Tar- taro, it is very unhealthy. The inhabitants are 9620. The chief trade is that of tanning leather. Long. 12. 2.E. Lat. 45. 2. N. ADRIAN, or Hadrian, Publius tElius, the Roman emperor. He was born at Rome on the 24th of January, in the 76th year of Christ, A. u. c. 829. His father left him an orphan, at ten years of age, under the guardianship of Trajan, and Coelius Tatianus, a Roman knight. He be¬ gan to serve very early in the armies, having been tribune of a legion before the death of Domitian. He was the person chosen by the army of Lower Mcesia to carry the news of Nerva’s death to Trajan, successor to the empire. Trajan, however, conceived some prejudices against him; and Adrian, perceiving that he was no favourite with the emperor, endeavoured to ingratiate himself with the em¬ press Plotina, by which means he succeeded in obtaining for his wife Sabina, the emperor’s grand-niece and next heiress. This was probably the first step to his future advancement, and facilitated his ascent to the throne. As questor he accompanied Trajan in most of his expedi¬ tions, and particularly distinguished himself in the second war against the Dacians. Afterwards he was successively tribune of the people, pretor, governor of Pannonia, and consul. After the siege of Atra in Arabia was raised, Trajan, who had already given him the government of Sy¬ ria, left him the command of the army; and at length, when he found death approaching, it is said he adopted him. Adrian, who was then in Antiochia, as soon as he received the news thereof, and of Trajan’s death, declared himself emperor, on the 11th August, A. d. 117. No sooner had he arrived at the imperial dignity than he made peace with the Persians, to whom he yielded up great part of the conquests of his predecessors ; and from generosity or policy he remitted the debts of the Roman people, which, according to the calculation of those who have reduced them to modern money, amounted to 22,500,000 golden crowns; and he burnt all the bonds and obligations relating to those debts, that the people might be under no apprehension of being called to an ac¬ count for them afterwards. There are medals in comme¬ moration of this fact, in which he is represented holding a flambeau in his hand, to set fire to all those bonds which he had made void. He went to visit all the provinces, and did not return to Rome till the year 118, when the senate decreed him a triumph, and honoured him with the title of Father of his Country ; but he refused both, and desired that Trajan’s image might triumph. No prince travelled more than Adrian, there being hardly one pro¬ vince in the empire which he did not visit. In 120 he v/ent into Gaul; from thence he w'ent over to Britain, in order to subdue the Caledonians, who were making con¬ tinual inroads into the provinces. Upon his arrival they retired towards the north. He advanced, however, as far as York, where he was diverted from his intended con¬ quest by the description there given him of the country ADR by some old soldiers who had served under Agricola. 'In hopes, therefore, of keeping them quiet by enlarging their bounds, he delivered up to the Caledonians all the lands lying between the two friths and the Tyne ; and at the same time, to secure the Roman province from their future incursions, built the famous wall which still bears his name.1 Having thus settled matters in Britain, he returned to Rome, where he was honoured with the title of Restorer of Britain, as appears by some medals. He soon after went into Spain, to Mauritania, and at length into the East, where he quieted the commotions raised by the Parthians. After having visited all the provinces of Asia, he returned to Athens in 125, where he passed the winter, and was initiated in the mysteries of Eleusinian Ceres. He went from thence to Sicily, chiefly to view Mount fEtna, contemplate its phenomena, and enjoy the beautiful and extensive prospect afforded from its top. He returned to Rome in the beginning of the year 129 ; and, according to some, he went again the same year to Africa; and, after his return from thence, to the East. He was in Egypt in the year 132, revisited Syria the year following, returned to Athens in 134, and to Rome in 135. The persecution against the Christians was very violent under his reign; but it was at length suspended, in con¬ sequence of the remonstrances of Quadratus, bishop of Athens, and Aristides, two Christian philosophers, who presented the emperor with some books in favour of the Christian religion. He conquered the Jews, and by way of insult erected a temple to Jupiter on Calvary, and placed a statue of Adonis in the manger of Bethlehem: he caused also the images of swine to be engraven on the gates of Jerusalem. At last he was seized with a dropsy, which vexed him to such a degree that he became almost raving mad. A great number of physicians were sent for, and to the multitude of them he ascribed his death. He died at Baiae in the 63d year of his age, having reigned 21 years. The Latin verses he addressed to his soul, which he composed a short time before his death, in a strain of tender levity, have been much criticised, and have been the subject of numerous translations and imi¬ tations.

He also w rote the history of his own life ; to which, however, he Adrian, dul not choose to put his name; but that of Phlegon, one of his freedmen, a very learned person, was prefixed to it. . He had great wit and a retentive memory, and he 2 Sparti- distinguished himself in the various branches of literature anus? in and science. In his natural disposition he was suspicious, envious, cruel, and lascivious. In his character there was a strange composition of virtues and vices. He was affable, courteous, and liberal; but he was capricious and unsteady in his attachments, and violent in his resentment. Thus he was distrusted by his friends, and dreaded by his ene¬ mies. Antoninus his successor obtained his apotheosis, and prevented the rescission of his acts, which the senate once intended. Adrian I. Pope, ascended the papal throne A. d. 772. He was the son of Theodore, a Roman nobleman, and possessed considerable talents for business. Lie maintain¬ ed a steady attachment to Charlemagne, which provoked Desiderius, a king of the Lombards, to invade the state of Ravenna, and to threaten Rome itself. Charlemagne rewarded his attachment by marching with a great army to his aid; and having gained many considerable advan¬ tages over Desiderius, he visited the pope at Rome, and expressed his piety by the humiliating ceremony of kiss¬ ing each of the steps as he ascended to the church of St Peter. The affairs of the church now' claimed Adrian’s particular attention; for Irene, who in 780 assumed the regency at Constantinople during the minority of her son Constantine, wishing to restore tlie worship of images, ap¬ plied to Adrian for his concurrence. The pontiff readily acquiesced in her proposal for calling a council, and com¬ missioned two legates to attend it. The first council, however, was dispersed by an insurrection of the citizens; but at the next meeting, in the city of Nice, in 787, which was protected by a military force, a decree was passed for restoring the worship of images. Adrian approved the decree, but in the western church it was deemed heretical and dangerous. Charlemagne condemned the innovation, and the French and English clergy concurred in opposing it. A treatise, containing 120 heads of refutation, was circulated as the work of Charlemagne, under the title of The Caroline Books, in opposition to the decree of the council. This work was presented to the pope by the king s ambassador, and the pope wrote a letter to Charle¬ magne by way of reply. The king, and also the Gallican and English churches, retained their sentiments; and in 794 a council was held at Frankfort on the Maine, consist¬ ing of about 300 western bishops, by which every kind of image-worship was condemned. Adrian did not live to see a termination of this contest; for after a pontificate of nearly twenty-four years, he died in 795. Adrian seems to have directed his chief attention to the embellishment of the churches and the improvement of the city of Rome; and he was probably furnished by Charlemagne, out of the plunder of his conquests, with ample means for this purpose. creen thou^ called by the Roman historians^ murus, which signifies a wall of stone, was only composed of earth covered with river Tvne on'ti!tCallfCl f°^/r01? tle Solway Frith, a little west of the village of Burgh on the Sands, in as direct a line as possible, to the 70 Roman mUoc, 5, TSt’ tha place where the town of Newcastle now stands; so that it must have been above (>0 English, and near 2.

ADRIANUM, or Adriaticum Mare, in Ancient Geo¬ graphy, now the Gulf of Venice, a large bay in the Me¬ diterranean, between Dalmatia, Sclavonia, Greece, and Italy. It is called by the Greeks A^/as KoXwos, and Adria by the Romans, (as Arbiter Advice Notus, Hor.) Cicero calls it Hadrianum Mare, Virgil has Hadriaticas Undas. It is commonly called Mare Adriaticum, without an aspiration; but whether it ought to have one, is a dis¬ pute. If the appellation is from Hadria, the town of the Piceni, it must be written Hadriaticum, because the em¬ peror’s name who thence derives his origin is on coins and stones Hadrianus ; but if from the town in the terri¬ tory of Venice, as the more ancient, and of which that of the Piceni is a colony, this will justify the common appel¬ lation Adriaticum. It extends from latitude 40. to 45.55. north, between the coasts of Italy and Illyria. I he tides in this sea are distinguishable, but the ebb and flow is incon¬ siderable, though greater than in the Mediterranean. AD RIP ALDA, a city in the province of Principato Ulteriore, in the kingdom of Naples. It is situated on the river Sabato, near to Avellino, The number of inhabitants is 4236, who carry on trade in cloth and paper, in iron and copper goods, and make large quantities of nails. ADROGATION, in Roman Antiquities, a species of adoption, whereby a person who was capable of choosing for himself was admitted by another into the relation of a son. The word is compounded of ad, to, and rogare, to ask, on account of a question put in the ceremony of it. Whether the adopter would take such a person for his son ? and another to the adoptive, Whether he con¬ sented to become such a person’s son ? ADSIDELLA, in Antiquity, the table at which the flamens sat during the sacrifices. . ADSTRICTION, among physicians, a term used to denote the rigidity of any part. ADVANCED, in a general sense, denotes something posted or situated before another. Thus, Advanced Ditch, in Fortification, is that which sur¬ rounds the glacis or esplanade of a place. Advanced Guard, or Vanguard, in the art of war, the first line or division of an army, ranged or marching in or¬ der of battle; or, it is that part which is next the enemy, and marches first towards them. Advanced Guard is more particularly used for a small party of horse stationed before the main guard. ADVENT, in the calendar, properly signifies the ap¬ proach of the feast of the nativity. It includes four Sun¬ days, and begins on St Andrew’s day or on the Sunday before or after it. During advent, and to the end of the octaves of epiphany, the solemnizing of marriage is for¬ bidden without a special licence. It is appointed to em¬ ploy the thoughts of Christians on the first advent or coming of Christ in the flesh, and his second advent or coming to judge the world. The primitive Christians prac¬ tised great austerity during this season. Ad ventrem inspiciendum, in Law, a writ by which a woman is to be searched whether she be with child by a former husband, on her withholding lands from the next, failing issue of her own body. . Tr „ Adventure Bay, the name of a bay in Van Diemens Land, so called by Captain Cook. 166 A D U A D U Adven¬ turer ADVENTURER, in a general sense, denotes one who ^ hazards something. Adult,?ra- Adventurers is particularly used for an ancient cona¬ tion. Pany merchants and traders, erected for the discovery of lands, territories, trades, Ax. unknown. The society of adventurers had its rise in Burgundy, and its first esta¬ blishment from John duke of Brabant in 1248, being known by the name of the Brotherhood of St Thomas a Bechet. It was afterwards translated into England, and successively confirmed by Edwards III. and IV. Richard III. Henries IV. V. VI. and VII. who gave it the appellation of Merchant Adventurers. A.DVERB, in Grammar, a particle joined to a verb, ad¬ jective, or participle, to explain their manner of acting or suffering, or to mark some circumstance or quality signi¬ fied by them. The word is formed from the preposition cul, to, and verbum, a verb ; and signifies literally a word joined to a verb, to show how, when, or where, one is, does, or suffers; as, the boy paints neatly, writes ill; the house stands there. Ax. ADVERSARIA, among the ancients, a book of ac¬ counts not unlike our journals or day-books. It is also used as a title for books of miscellaneous remarks and ob¬ servations. ADVERSATIVE, in Grammar, a word expressing some difference between what goes before and what fob lows it. Thus, in the phrase, he is an honest man, but a great enthusiast, the word but is an adversative conjunction. ADVERSAfOR, in Antiquity, a servant who attended the rich in returning from supper, to give them notice of any obstacles in the way, on which they might be apt to stumble. . ADVERTISEMENT, in a general sense, denotes any information given to persons interested in an affair; and is more particularly used for a brief notice inserted in the public papers, for the information of all concerned. ADULA, in Ancient Geography, a mountain in Rhaetia, or the country of the Orisons, part of the Alps, in which are the fountains of the Rhine; now St Gothard. ADULE, or Adulis, in Ancient Geography, a town of ®Sypb built by fugitive slaves, distant from its port on the Red Sea 20 stadia. Pliny calls the inhabitants Adulitce. The epithet is either Adulitanus, as Monumentum Adu- htanum, on the pompous inscription of the statue of Ptolemy Euergetes^ published by Leo Alatius at Rome in 1631, and to be found in Spon and Thevenot; or Adu- licus, as Adulicus Sinus, a part of the Red Sea. . ADULT, an appellation given to any thing that is ar¬ rived at maturity : thus, we say an adult person, an adult plant, Ax. Among civilians, it denotes a youth between 14 and 25 years of age. ADULIERATION, the act of debasing, by an impro¬ per mixture, something that was pure and genuine. The word is Latin, formed of the verb, adulterare, to cor¬ rupt, by mingling something foreign to any substance. Adulteration of Coin properly imports the making or casting of a wrong metal, or with too base or too much al¬ loy. Adulterations of coins are effected divers ways : as, by forging another stamp or inscription; by mixing im¬ pure metals with the gold or silver; by making use of a wrong metal, or an undue alloy, or too great an admixture of the baser metals with gold or silver. Counterfeiting the stamp, or clipping and lessening the weight, does not so properly come under the denomination of adulterating. Ibis term is somewhat less extensive than debasing, which includes diminishing, clipping, Ax. To adulterate or de¬ base the current coin is a capital crime in all nations. I he ancients punished it with great severity. Among the ^Sjpbans both hands were cut off, and by the civil law the offender was thrown to wild beasts. The emperor Adu Tacitus enacted, that counterfeiting the coin should be ^ capital; and under Constantine it was made treason, as it AdltrT. is also among us. ' ADULTERINE, in the Civil Law, is particularly ap¬ plied to a child issued from an adulterous amour or com¬ merce. Adulterine children are more odious than the il¬ legitimate offspring of single persons. The Roman law even refuses them the title of natural children, as if na¬ ture disowned them. Adulterine children are not easily dispensed with for admission to orders. Those are not deemed adulterine who are begotten of a woman openly married, through ignorance of a former wife being alive. By a decree of the parliament of Paris, adulterine children are declared not legitimated by the subsequent marriage of the parties, even though a papal dispensation be had for such marriage, wherein is a clause of legitimation. Adulterine Marriages, in St Augustine’s sense, de¬ note second marriages contracted after a divorce. ADULIERY, an unlawful commerce between one married person and another, or between a married and unmarried person. Punishments have been annexed to adultery in most ages and nations, though of different degrees of severity. In many it has been capital ; in others venial, and attend¬ ed only with slight pecuniary mulcts. Some of the pe¬ nalties are serious, and even cruel; others of a jocose and humorous kind. Even contrary things have been enacted as punishments for adultery. By some laws the crimi¬ nals are forbidden marrying together in case they become single ; by others they are forbidden to marry any besides each other: by some they are incapacitated from ever committing the like crime again ; by others they are glut¬ ted with it till it becomes nauseous. Among the rich Greeks, adulterers were allowed to re¬ deem themselves by a pecuniary fine: the woman’s fa¬ ther, in such cases, returned the dower he had received from her husband, which some think was refunded by the adulterer. Another punishment among those people was putting out the eyes of adulterers. I he Athenians had an extraordinary way of punishing adulterers, called a.'irogacpu.vthoRn; vagariX/Ao;, practised at least on the poorer sort who were not able to pay the fines. This was an awkward sort of empalement, performed by thrusting one of the largest radishes up the anus of the adulterer, or, in defect thereof, a fish with a large head, called mugil, mullet. Alcaeus is said to have died in this way, though it is doubted whether the punishment was icputed mortal. Juvenal and Catullus speak of this cus¬ tom as received also among the Romans, though not au¬ thorized by an express law, as it was among the Greeks. There are various conjectures concerning the ancient punishment of adultery among the Romans. Some will have it to have been made capital by a law of Romulus, and again by the twelve tables; others, that it was first made capital by Augustus; and others, not before the emperor Constantine. The truth is, the punishment in the early days was very various, much being left to the discretion of the husband and parents of the adulterous wife, who exercised it differently, rather with the silence and countenance of the magistrate than by any formal au- thonty from him. Thus, we are told the wife’s father was allowed to kill both parties, when caught in the fact, pro¬ vided he did it immediately, killed both together, and as it were with one blow. The same power ordinarily was not indulged the husband, except the crime were commit¬ ted with some mean or infamous person ; though, in other cases, if his rage carried him to put them to death, he was not punished as a murderer. On many occasions^ A D U A D V 167 >rv however, revenge was not carried so far ; but mutilating, ^castrating, cutting off the ears, noses, &c. served the turn. The punishment allotted by the lex Julia was not, as many have imagined, death, but rather banishment or deportation, being interdicted fire and water ; though Oc¬ tavius appears in several instances to have gone beyond his own law, and to have put adulterers to death. Under Macrmus, many were burnt at a stake. C onstantine first by law made the crime capital. Under Constantius and Constans, adulterers were burnt, or sewed in sacks and thrown into the sea. Under Leo and Marcian, the penalty was abated to perpetual banishment, or cutting off the nose. Under Justinian, a further mitigation was granted, at least in favour of the wife, who was only to be scourged, lose her dower, and be shut up in a monastery. After two years, the husband was at liberty to take her back again; if he refused, she was shaven, and made a nun for life; but it still remained death in the husband. The reason alleged for this difference is, that the woman is the weaker vessel. Matthaeus declaims against the empress Theodora, who is supposed to have been the cause of this law, as well as of others procured in favour of that sex from the emperor. Under Theodosius, women convicted of this crime were punished after a very singular manner, viz. by a public constupration; being locked up in a narrow cell, and forced to admit to their embraces all the men that would offer themselves. To this end the gallants were to dress themselves on purpose, having several little bells fasten¬ ed to their clothes, the tinkling of which gave notice to those without of every motion. This custom was abolish¬ ed by the same prince. By the Jewish law, adultery was punished with death in both parties, where they were both married, or only the woman. The Jews had a particular trial or ordeal for a woman suspected of the crime, by making her drink the bitter waters of jealousy ; which, if she were guilty, made her swell. Amongst the Mingrelians, according to Chardin, adul¬ tery is punished with the forfeiture of a hog, which is usually eaten in good friendship between the gallant, the adulteress, and the cuckold. In some parts, of the Indies, it is said any man’s wife is permitted to prostitute herself to him who will give an elephant for the use of her; and it is reputed no small glory to her to have been rated so high. Adultery is said to be so frequent in Ceylon, that there is not a woman who does not practise it, notwith¬ standing its being punishable with death. Among the Japanese, and divers other nations, adultery is only penal in the woman. In the Marian islands, the woman is not punishable for adultery; but if the man go astray he pays severely; the wife and her relations waste his lands, turn him out of his house, &c. In Spain they punished adultery in men by cutting off the instrument of the crime. In Poland, before Christi¬ anity was established, they punished adultery and forni¬ cation in a particular manner : the criminal they carried to the market-place, and there fastened him by the offend¬ ing part with a nail, laying a razor within his reach, and leaving him under a necessity either of doing justice upon himself, or of perishing in that condition. In England adultery by the ancient laws was severely punished. King Edmund the Saxon ordered it to be punished in the same manner as homicide; and Canute the Dane ordered that a man who committed adultery should be banished, and that the woman should have her nose and ears cut off. In the time of Henry I. it was punished with the loss of eyes and genitals. In Britain adultery is now reckoned a spiritual offence, that is, cognizable by the spiritual courts, where it is Adultery punished by fine and penance. The common law takes no I! further notice of it than to allow the party aggrieved an Advocate, action and damages. This practice is often censured by foreigners, as making too light of a crime, the bad conse¬ quences of which, public as well as private, are so great. It has been answered, that perhaps this penalty, by civil action, joined with the ignominy attached to it, is more calculated to prevent the frequency of the offence, which ought to be the end of all laws, than a severer punishment. Adultery is, both in England and Scotland, a ground of divorce ; but in the former a complete divorce can only be obtained through an act of parliament, whereas in the latter a complete divorce may be effected by the sentence of the consistorial or commissary court. The adulterous parties are by the law of Scotland prohibited from inter¬ marrying with each other. See Divorce. Adultery is used in Scripture for idolatry, or depart¬ ing from the true God to the worship of a false one. Adultery is used by ecclesiastical writers for a per¬ son’s invading or intruding into a bishopric during the former bishop’s life. The reason of the appellation is, that a bishop is supposed to contract a kind of spiritual marriage with his church. The translation of a bishop from one see to another was also reputed a species of adultery, on the supposition of its being a kind of second marriage, which in those days was esteemed a degree of adultery. This conclusion was founded on the text of St Paul, Let a bishop be the husband of one wife ; by a forced construction of church for wife, and of bishop for husband. Adultery is used by ancient naturalists for the act of ingrafting one plant upon another ; in which sense Pliny speaks of the adulteries of trees, arborum adulteria, which he represents as contrary to nature, and a piece of luxury or needless refinement. ADVOCATE, among the Romans, a person skilled in their law, who undertook the defence of causes at the bar. The Roman advocates answered to one part of the office of a barrister in England, viz. the pleading part; for they never gave counsel, that being the business of thejuris- consulti. The Romans, in the first ages of their state, held the profession of an advocate in great honour; and the seats of their bar were crowded with senators and consuls, they whose voices commanded the people thinking it an honour to be employed in defending them. They were styled comites, honorati, clarissimi, and even patroni; as if their clients were not less obliged to them than freed- men to their masters. The bar was not at that time venal. Those who aspired to honours and offices took this way of gaining an interest in the people, and always pleaded gratis. But no sooner were luxury and corruption intro¬ duced into the commonwealth, than the bar became a sharer in them. Then it was that the senators let out their voices for pay, and zeal and eloquence were sold to the highest bidder. To put a stop to this abuse, the tri¬ bune Cincius procured a law to be passed, called from him Lex Cincia, whereby the advocates were forbidden to take any money of their clients. It had before this been prohibited the advocates to take any presents or gratuities for their pleading. The emperor Augustus added a pe¬ nalty to it; notwithstanding which, the advocates played their part so well, that the emperor Claudius thought it an extraordinary circumstance, when he obliged them not to take above eight great sesterces, which are equivalent to about L.64 sterling, for pleading each cause. Advocate is still used in countries and courts where the civil law obtains, for those who plead and defend the causes of clients intrusted to them. 168 A D V A D V Advocates. Advocate of a City, in the German polity, a magistrate 'appointed in the emperor’s name to administer justice. Advocate is more particularly used in church history for a person appointed to defend the rights and revenues of a church or religious house. The word advocatus, or advowee, is still retained for what we usually call the pa¬ tron, or he who has the advowson or right of presentation in his own name. Consistorial Advocates, officers of the consistory at Rome, who plead in all oppositions to the disposal of be¬ nefices in that court. They are ten in number. Elective Advocates, those chosen by the abbot, bishop, or chapter, a particular licence being had from the king or prince for that purpose. The elections were originally made in the presence of the count of the province. Feudal Advocates. These were of the military kind, who, to make them more zealous for the interest of the church, had lands granted them in fee, which they held of the church, and did homage and took an oath of fide¬ lity to the bishop or abbot. These were to lead the vas¬ sals of the church to war, not only in private quarrels of the church itself, but in military expeditions for the king’s service, in which they were the standard-bearers of their churches. Fiscal Advocate, fisci advocatus, in Roman Antiquity, an officer of state under the Roman emperors, who plead¬ ed in all causes wherein the fiscus or private treasury was concerned. Juridical Advocates, in the middle age, were those who, from attending causes in the court of the comes or count of the province, became judges themselves, and held courts of their vassals thrice a year, under the name of the trio, placita generalia. In consideration of this fur¬ ther service, they had a particular allowance of one third part of all fines or mulcts imposed on defaulters, &c. besides a proportion of diet for themselves and servants. Matricular Advocates were the advocates of the mo¬ ther or cathedral churches. Military Advocates, those appointed for the defence of the church, rather by arms and authority than by plead¬ ing and eloquence. These were introduced in the times of confusion, when every person was obliged to maintain his own property by force. Bishops and abbots not being permitted to bear arms, and the scholastic or gowned ad¬ vocates being equally unacquainted with them, recourse was had to knights, noblemen, soldiers, or even to princes. Nominative Advocates, those appointed by a king or pope. Sometimes the churches petitioned kings, &c. to appoint them an advocate ; at other times this was done of their own accord. By some regulations, no person was capable of being elected advocate unless he had an estate in land in the same country. Regular Advocates, those duly formed and qualified for their profession by a proper course of study, the re¬ quisite oath, subscription, licence, &c. Subordinate Advocates, those appointed by other su¬ perior ones, acting under them, and accountable to them. There are various reasons for the creation of these subor¬ dinate advocates ; as, the superior quality of the principal advocate, his being detained in war, or being involved in other affairs; but chiefly the too great distance of some of the church-lands, and their lying in the dominions of foreign princes. Supreme Sovereign Advocates were those who had the authority in chief, but acted by deputies or subordinate advocates. These were called also principal, greater, and sometimes general advocates. Such, in many cases, were kings, &c. wdien they had either been chosen advocates, or became such by being founders or endowers of churches. Princes had also another title to advocateship, some of a them pretending to be advocati nati of the churches with- ' in their dominions. ^ Advocates, in the English courts, are more eenerallv^ l called counsel. 6 y ' Facidty of Advocates, in Scotland, a respectable body of lawyers, who plead in all causes before the courts of session, justiciary, and exchequer. They are also enti¬ tled to plead in the house of peers and other supreme courts in England. A candidate for the office of an advocate undergoes three several trials : the first is in Latin, upon the civil law, and Greek and Roman antiquities; the second, in English, upon the municipal law of Scotland; and, in the third, he is obliged to defend a Latin thesis, which is im¬ pugned by three members of the faculty. All this, how- ever, has become very much matter of form. Immediately before putting on the gown, the candidate makes a short Latin speech to the lords, and then takes the oaths to the government and defideli. The faculty at present (1829) consists of 324 members. As the profession of an advocate is esteemed the genteelest in Scotland, many gentlemen of fortune become members of the faculty without having any intention of practising at the bar. This circumstance greatly increases their num¬ ber, gives dignity to the profession, and enriches their library and public fund. It is from this respectable body that all vacancies on the bench are generally supplied. Lord Advocate, or Kings Advocate, one of the eight great officers of state in Scotland, who as such sat in par¬ liament without election. Pie is the principal crown lawyer in Scotland. His business is to act as a public prosecutor, and to plead in all causes that concern the crown, but particularly in such as are of a criminal nature. The office of king s advocate is not very ancient: it seems to have been established about the beginning of the six¬ teenth century. Originally he had no powder to prosecute crimes without the concurrence of a private party; but, in the year 1597, he was empowered to prosecute crimes at his own instance. He has the privilege of pleading in court with his hat on. This privilege was first granted to Sir Thomas Hope, who having three sons lords of ses¬ sion, it was thought indecent that the father should plead uncovered before the sons, who as judges sat covered. AD\ OCATION, in Scotish Law, a mode of appeal from certain inferior courts to the supreme court. The writ employed is called a Fill of Advocation. AD VOW EE, in ancient customs and law-books, denotes the advocate of a church, religious house, or the like. I here were advowees of cathedrals, abbeys, monasteries, &c. Thus, Charlemagne had the title of advowee of St Peter s ; King Hugh, of St Riquier; and Bolandus men¬ tions some letters of Pope Nicholas, by which he consti¬ tuted King Edward the Confessor and his successors ad¬ vowees of the monastery at Westminster, and of all the churches in England. These advowees were the guardians, piotectors, and administrators of the temporal concerns of the churches, &c.; and under their authority were passed all contracts which related to them. It appears also, from tie most ancient charters, that the donations made to churches were conferred on the persons of the advowees. 4 hey always pleaded the causes of the churches in court, and distributed justice for them, in the places under their jurisdiction. They also commanded the forces furnished by their monasteries, &c. for the war; and even were their champions, and sometimes maintained duels for them. This office is said to have been first introduced in the fourth century, in the time of Stillico; though the Bene¬ dictines do not fix its origin before the eighth century. By Udv'P-6 Ljvovon A D V degrees men of the first rank were brought into it, as it was found necessary either to defend with arms or to pro¬ tect with power and authority. In some monasteries they were only called conservators; but these, without the name, had all the functions of advowees. There were also sometimes several sub-advowees or sub-advocates in each monastery, who officiated instead of the advowees themselves; which, however, proved the ruin of monas¬ teries, those inferior officers running into great abuses. Hence also, husbands, tutors, and every person in ge¬ neral who took upon him the defence of another, were denominated advowees or advocates. Hence several cities had their advowees, which were established long after the ecclesiastical ones, and doubtless from their example. Thus, we read in history of the advowees of Augsburg, of j^rraS The vidames assumed the quality of advowees ; and hence it is that several historians of the eighth century confound the two functions together. Hence also it is that several secular lords in Germany bear mitres for their crests, as having anciently been advowees of the great churches. . Spelman distinguishes two kinds of ecclesiastical ad¬ vowees : the one, of causes or processes, advocati causa- rum ; the other, of territory or lands, advocati soli. The former were nominated by the king, and were usually lawyers, who undertook to plead the causes of the monas¬ teries. The other, which still subsist, and are sometimes called by their primitive name, advowees, though more usually patrons, were hereditary, as being the founders and endowers of churches, &c. or their heirs. Women were sometimes advowees, advocatissw; and the canon law mentions some who had this title, and who had the same right of presentation, &c. in their churches which the advowees themselves had. In statute 25 Edw. III. we meet with advowee paramount for the highest patron; that is, the king. ADVOWSON, or Advowzen, in Common Law, sig¬ nifies a right to present to a vacant benefice. Advowson is so called because the right of presenting to the church was first gained by such as were founders, benefactors, or maintainers of the church. Though the nomination of fit persons to officiate in every diocese was originally in the bishop, yet they were content to let the founders of churches have the nomination of the persons to the churches so founded, reserving to themselves a right to judge of the fitness of the persons nominated.—Advow- sons formerly were most of them appendant to manors, and the patrons were parochial barons. The lordship of the manor and patronage of the church were seldom in different hands, until advowsons were given to religious houses. But of late times the lordship of the manor and advowson of the church have been divided.—Advow¬ sons are presentative, collative, or donative: presentative, where the patron presents or offers his clerk to the bishop of the diocese, to be instituted in his church; collative, where the benefice is given by the bishop, as original pa¬ tron thereof, or by means of a right he has acquired by lapse; donative, where the king or other patron does, by a single donation in writing, put the clerk into posses¬ sion, without presentation, institution, or induction. Sometimes, anciently, the patron had the sole nomina¬ tion of the prelate, abbot, or prior, either by investiture (i. e. delivery of a pastoral staff) or by direct presentation to the diocesan; and if a free election was left to the brother¬ hood, yet a conge delire, or licence of election, was first to be obtained of the patron, and the person elected was confirmed by him. If the founder’s family became extinct, the patronage of the convent went to the lord of the ma- VOL. II. iE A C nor.—Advowsons are temporal inheritances and lay fees : they may be granted by deed or will, and are assets in the hands of heirs or executors. Presentations to advow¬ sons for money or other reward are void. (31 Eliz. cap. 6.) In Scotland this right is called patronage. ADY, in Natural History, a name given to the palm-tree of the island of St Thomas. It is a tall tree, with a thick, bare, upright stem, growing single on its root, of a thin light timber, and full of juice. The head of this tree shoots into a vast number of branches, which being cut off, or an incision being made therein, afford a great quantity of sweet juice, which, fermenting, supplies the place of wine among the Indians. The fruit of this tree is called by the Portuguese caryoces and cariosse, and by the black natives abanga. This fruit is of the size and shape of a lemon, and contains a kernel, which is good to eat. The fruit itself is eaten roasted, and the raw kernels are often mixed with mandioc meal. These kernels are supposed very cordial. An oil is also prepared from this fruit, which answers the purpose of oil or butter. Ihis oil is also used for anointing stiff and contracted parts of the body. ADYNAMIA, in Medicine, of a privative, and buvaiMig, strength, want of power, debility or weakness from sickness. ADYNAMON, among ancient physicians, a kind of weak factitious wine, prepared from must boiled down with water, to be given to patients to whom genuine wine might be hurtful. ADYTUM, in Pagan Antiquity, the most retired and sacred place of temples, into which none but the priests were allowed to enter. The Sanctum Sanctorum of the temple of Solomon was of the nature of the pagan adytum, none but the high-priest being admitted into it, and he but once a year. ADZE, or Addice, a cutting tool of the axe kind, having its blade made thin and arching, and its edge at right angles to the handle ; chiefly used for taking off thin chips of timber or boards, and for paring away certain ir¬ regularities which the axe cannot come at. The adze is used by carpenters, but more by coopers, as being con¬ venient for cutting the hollow sides of boards, &c. It is ground from a base on its inside to its outer edge ; so that, when it is blunt, they cannot conveniently grind it without taking its helve out of the eye. AE, or M, a diphthong compounded of A and E. Authors are by no means agreed as to the use of the w in English words. Some, out of regard to etymology, insist on its being retained in all words, particularly technical ones, borrowed from the Greek and Latin; while others, from a consideration that it is no proper diphthong in our language (its sound being no other than that of the sim¬ ple e), contend that it ought to be entirely disused; ami in fact the simple e has of late been adopted instead of the Roman ce, as in the word equator, &c. yEACEA, in Grecian Antiquity, solemn festivals and games celebrated at iEgina in honour of iEacus. ABACUS, the son of Jupiter by TEgina. When the isle of iEgina was depopulated by a plague, his father, in compassion to his grief, changed all the ants upon it into men and women, who were called Myrmidones, from an ant. The foundation of the fable is said to be, that when the country had been depopulated by pirates, who forced the few that remained to take shelter in caves, yEacus encouraged them to come out, and by commerce and industry recover what they had lost. His character for justice was such, that, in a time of universal drought, he was nominated by the Delphic oracle to intercede for Greece, and his prayer was answered. See the article jEgina. The Pagans also imagined that iEacus, on ac- Y 169 Ady II yEacus. 170 M D I M G I ^Cdile. jEhudse count of his impartial justice, was chosen by Pluto one of 11 the three judges of the dead; and that it was his pro¬ vince to judge the Europeans. /EBUDiE, a name anciently given to the Western Islands of Scotland. JECIIMALO TA RCH A, in Jewish Antiquity, a title given to the principal leader or governor of the Hebrew captives residing in Chaldea, Assyria, and the neighbour¬ ing countries. This magistrate was called by the Jews rasch-galuth, i. e. the chief of the captivity ; but the above term, of like import in the Greek, is that used by Origen and others who wrote in the Greek tongue. iEDES, in Roman Antiquity, besides its more ordinary signification cf a house, likewise signified an inferior kind of temple, consecrated to some deity. vEDICULA, a term used to denote the inner part of the temple, where the altar and statue of the deity stood. iEDILE (fp.dilis), in Roman Antiquity, a magistrate whose chief business was to superintend buildings of all kinds, but more especially public ones, as temples, aque¬ ducts, bridges, &c. To the aediles likewise belonged the care of the highways, public places, weights and mea¬ sures, &c. They also fixed the prices of provisions, took cognizance of debauches, punished lewd women and such persons as frequented gaming-houses. The custody of the plebiscita, or orders of the people, was likewise committed to them. They had the inspection of comedies and other pieces of wit; and were obliged to exhibit magnificent games to the people, at their own expense, whereby many of them were ruined. They had the power, on certain occasions, of issuing edicts, and by degrees they procured to themselves a considerable jurisdiction. All these func¬ tions, which rendered the aediles so considerable, belonged at first to the aediles of the people, cedilesplebeii, or minores. These were only tw o in number, and were first created in the same year as the tribunes; for the tribunes, finding themselves oppressed with the multiplicity of affairs, demanded of the senate to have officers to whom they might intrust mat¬ ters of less importance ; and accordingly two aediles were created; and hence it was that the aediles were elected every year at the same assembly as the tribunes. But these plebeian aediles having refused, on a signal occasion, to treat the people with shows, pleading that they were un¬ able to support the expense thereof, the patricians made an offer to do it, provided they would admit them to the honours of the wdilate. On this occasion there were two new aediles created, of the number of the patricians, in the year of Rome 388. They were called cediles curules, or ma- jores, as having a right to sit on a curule chair, enriched with ivory, wRen they gave audience; whereas the ple¬ beian aediles only sat on benches. Besides that the curule aediles shared all the ordinary functions with the plebeian, their chief employment was, to procure the celebration of the grand Roman games, and to exhibit comedies, shows of gladiators, &c. to the people; and they were also ap¬ pointed judges in all cases relating to the selling or ex¬ changing of estates. To ease these first four aediles, Csesar created a new kind, called cediles cereales, as being deputed chiefly to take care of the corn, which was called donum Cerens; for the heathens honoured Ceres as the goddess who presided over corn, and attributed to her the inven¬ tion of agriculture. These 'aediles cereales were also taken out of the order of patricians. In the municipal cities there were aediles, and with the same authority as at Rome. We also read of an cedilis alimentarius, expressed in ab¬ breviature by JEdil. alim. whose business seems to have been to provide diet for those who were maintained at the public charge, though others assign him a different office. —In an ancient inscription we also meet with ccdile of the $<] camp, cedilis castrorum. iEDILITIUM Edictum, among the Romans, was that «, whereby a remedy was given to a buyer in case a vicious^ or unsound beast or slave was sold to him. It was call¬ ed cedilitium, because the preventing of frauds in sales and contracts belonged especially to the curule aediles. iEDITUUS, in Roman Antiquity, an officer belonging to the temple, who had the charge of the offerings, treasure, and sacred utensils. The female deities had a female officer of this kind called AEditua. iEGADES, islands off the western coast of Sicily, be¬ tween Trapani and Marsala, consisting of Maritime, Le- vanso, and Favignana, which were of some note during the first Punic war. A2GAGROPILA, a ball composed of hair, generated in the stomach of the chamois goat, which is similar to those found in cows, hogs, &c. There is another species of ball found in some animals, particularly horses, which is a calculous concretion. AEGEAN Sea, in Ancient Geography, now the Archi¬ pelago, a part of the Mediterranean, separating Europe from Asia Minor; washing, on the one hand, Greece and Macedonia ; on the other, Caria and Ionia. The origin of the name is greatly disputed. Festus advances three opinions: one, that it is so called from the many islands therein appearing at a distance like so many goats; an¬ other, because iEgea, queen of the Amazons, perished in it ; a third, because ^Egeus, the father of Theseus, threw himself headlong into it. j iEGEUS, in fabulous history, was king of Athens, and the father of Theseus. The Athenians having basely killed the son of Minos, king of Crete, for carrying away the prize from them, Minos made war upon them; and being victorious, imposed this severe condition on -'Egeus, that he should annually send into Crete seven of the noblest of the Athenian youths, chosen by lot, to be devoured by the Minotaur. ‘ On the fourth year of this tribute, the choice fell on Theseus; or, as others say, he himself entreated to be sent. The king, at his son’s de¬ parture, gave orders, that as the ship sailed with black sails, it should return with the same in case he perished; but, if he became victorious, he should change them into white. When Theseus returned to Crete, after killing the Minotaur, and forgot to change the sails in token of his victory, according to the agreement with his father, the latter, who watched the return of the vessel, supposing by the black sails that his son was dead, cast himself head¬ long into the sea, which afterwards obtained the name of the AEgean Sea, The Athenians decreed YEgeus divine honours, and sacrificed to him as a marine deity the adopted son of Neptune. among physicians, a white speck on the pupil of the eye, which occasions a dimness of sight. iEGIDA, now Capo d’Istria, the principal town on the north of the territory of Istria, situated in a little island, joined to the land by a bridge. In an inscription it is called AEgidis Insula. Long. 14. 20. E. Lat. 45. 50. N. It was afterwards called Justinopolis, after the emperor Justinus. iEGILOPS, the name of a tumour in the great angle of the eye, either with or without an inflammation. The word is compounded of a/^, goat, and u^, eye ; as goats are supposed extremely liable to this distemper. If the aegilopsbe accompanied with an inflammation, it is supposed to take its rise from the abundance of blood which a ple¬ thoric habit discharges on the corner of the eye. If it be without an inflammation, it is supposed to proceed from a viscous pituitous humour, thrown upon this part. The M G I ii irus method of cure is the same as that of the ophthalmia. ^ But before it has reached the lachrymal passages, it is iia. managed like other ulcers. If the aegilops be neglected, ,'v"/it bursts, and degenerates into a fistula, which eats into the bone. . . . . , iEGIMURUS, in Ancient Geography, an island in the bay of Carthage, about 30 miles distant from that city, (Livy); now the Goletta. This island being afterwards sunk in the sea, two of its rocks remained above water, which were called Arm, because the Romans and Carthaginians entered into an agreement or league to limit their respec¬ tive boundaries by these rocks. iEGINA, in fabulous history, the daughter of Asopus, kino- of Bceotia, was beloved by Jupiter, who debauched heAn the similitude of a lambent flame, and then carried her fromEpidaurus to a desert island called CEnopia, which afterwards obtained her own name. TEgina, in Ancient Geography, an island in the Saronic gulf, 20 miles distant from the Piraeus, formerly vying with Athens in naval power, and at the sea-fight of Salamis disputing the palm of victory with the Athenians. It was the country and kingdom of iEacus, who called it AEgina, from his mother’s name, it being before called (Enopia. (Ovid.) The inhabitants were called JEginetm, and Mginenses. The Greeks had a common temple dedi¬ cated to Jupiter in iEgina, the remains of which still exist. The (Eginetae applied themselves to commerce, and were the first who coined money called No/wc/ia A/y/va/ov; hence AEgineticum ms, formerly in great repute. The inhabit¬ ants were called Myrmidones, or a nation of ants, from their great application to agriculture. The island was reckoned 180 stadia, or 22 miles and a half, in circumfer¬ ence. It is now called AEgina, the g soft and the i short, and was generally the seat of the Greek government in 1828 and 1829. The temple above mentioned is situ¬ ated upon the summit of a mountain called Panhellenius, at some distance from the shore. It was of the Doric or¬ der, and had six columns in front. Twenty-one of the exterior columns are yet standing, with two in the front of the pronaos and of the posticum, and five of the number which formed the ranges of the cell. The entablature, except the architrave, is fallen. The stone is of a light brownish colour, much eaten in many places, and indicating a very great age. Some of the columns have been injured by boring to their centres for the metal. In several, the junction of the parts is so exact that each seems to con¬ sist of one piece. This ruin Mr Chandler considers as scarcely to be paralleled in its claim to a remote antiquity. The situation, on a lonely mountain at a distance from the sea, has preserved it from total demolition amid all the changes and accidents of numerous centuries. The soil of this island is, as described by Strabo, very stony, es¬ pecially the bottoms; but in some places not unfertile in grain. Besides corn, it produces olives, grapes, and al¬ monds ; and abounds in pigeons and partridges. It has been related, that the TEginetans annually wage war with the feathered race, carefully collecting or breaking their eggs, to prevent their multiplying to such numbers as to produce a famine. They have no hares, foxes, or wolves. The rivers in summer are all dry. (Egina, the capital of the above island. Its site has been long forsaken. Instead of the temples mentioned by Pausanias, there are 13 lonely churches, all very mean ; and two Doric columns supporting their architrave. These stand by the sea-side, towards the low cape ; and, it has been supposed, are a remnant of a temple of Venus, which was situated by the port principally frequented. The walls belonging to the ports and arsenal were of excellent masonry, and may be traced to a considerable extent, JE G I 171 above, or nearly even with the water. At the entrance /Egineta of the mole, on the left, is a small chapel of St Nicholas ; li. and opposite, a square tower with steps before it, detach- ^gls* ed from which a bridge was laid across, to be removed on^-^^^^ any alarm. This structure, which is mean, was erected by the Venetians while at war with the Turks in 1693. iEGINETA, Paulus, a celebrated surgeon of the island of iBgina, from whence he derived his name. According to M. le Clerc’s calculation, he lived in the fourth cen¬ tury; but Abulfaragius the Arabian, who is allowed to give the best account of those times, places him with more probability in the seventh. His knowledge in surgery was very great, and his works are deservedly famous. Fabricius ab Aquapendente has thought fit to transcribe him in a great variety of places. Indeed, the doctrine of Paulus fEgineta, together with that of Celsus and Albu- casis, make up the whole text of this author. He is the first writer who takes notice of the cathartic quality of rhubarb ; and, according to Dr Milward, is the first in all antiquity who deserves the title of man-midwife. 7EGINHARD, the celebrated secretary and supposed son-in-law of Charlemagne. He is said to have been car¬ ried through the snow on the shoulders of Imma, to pre¬ vent his being traced from her apartments by the empe¬ ror her father; a story which the elegant pen of Addi¬ son has copied and embellished in the third volume of the Spectator. There is a letter of AEginhard’s still extant, lamenting the death of his wife, written in the tenderest strain of connubial affliction : but it does not say that this lady was the affectionate princess ; and indeed some late critics have proved that Imma was not the daughter of Charlemagne. He was a native of Germany, and educat¬ ed by the munificence of his imperial master, of which he has left the most grateful testimony in his preface to the life of that monarch. fEginhard, after the loss of his wife, is supposed to have passed the remainder of his days in religious retirement, and to have died soon after the year 840. His life of Charlemagne, his annals from 741 to 889, and his letters, are all inserted in the 2d volume of Duchesne’s Scriptores Francorum. An improved edi¬ tion of this valuable historian, with the annotations of Hermann Schmincke, in 4to, was published in 1711. iEGIPAN, m Heathen Mythobgy, a denomination given to the god Pan, because he was represented with the horns, legs, feet, &c. of a goat. AEGIPPIILA, in Botany, Goat-friend. AEGIS, in Ancient Mythology, a name given to the shield or buckler of Jupiter and Pallas. The goat Amal- thsea, which had suckled Jove, being dead, that god is said to have covered his buckler with the skin; whence the appellation mgis, from a/g, a/yog, she-goat. Jupiter afterwards restored the animal to life, covered it with a new skin, and placed it among the stars. He made a present of his buckler to Minerva; whence that goddess s buckler is also called mgis. Minerva having killed the Gorgon Medusa, nailed her head in the middle of the aegis, which henceforth had the faculty of converting into stone all those who looked upon it; as Medusa herself had during her life. Others suppose the aegis not to have been a buckler, but a cuirass or breastplate; and it is certain that the aegis of Pallas, described by Virgil, AEn. lib. viii. ver. 435, must have been a cuirass, since that poet says expressly that Medusa’s head was on the breast of the goddess. But the aegis of Jupiter, mentioned a little higher, ver. 354, seems to have been a buckler. The words— Cum ssepe nigrantem jEgida concuteret dextra, are descriptive of a buckler, but not at all of a cuirass or 172 IE L F /Elfric. jEgisthus breastplate. Servius makes the same distinction on the two passages of Virgil; for on verse 354 he takes the ^ aegis for the buckler of Jupiter, made, as above mentioned, of the skin of the goat Amalthaea; and on verse 435 he describes the aegis as the armour which covers the breast, and which in speaking of men is called cuirass, and aegis in speaking of the gods. Many authors have overlooked these distinctions for want of going to the sources. iEGISTHUS, in Ancient History, was the son of Thyes- tes by his own daughter Pelopea, who, to conceal her shame, exposed him in the woods. Some say he was taken up by a shepherd, and suckled by a goat; whence he was called JEgisthus. He seduced Clytemnestra, the wife of Agamemnon, and lived with her during the siege of Troy. Afterwards with her assistance he slew her hus¬ band, and reigned seven years in Mycenae. He was, to¬ gether with Clytemnestra, slain by Orestes. Pompey used to call Julius Caesar JEgisthus, on account of his having seduced his wife Mutia, whom he afterwards put away, though he had three children by her. iEGIUM, in Ancient Geography, a town of Achaia Propria, five miles from the place where Helice stood, and famous for the council of the Achaeans, which usually met there, on account probably of the commodious situation of the place. fEGOBOLIUM, in Antiquity, the sacrifice of a goat offered to Cybele. The asgobolium was an expiatory sacri¬ fice, which bore a near resemblance to the taurobolium and criobolium, and seems to have been sometimes joined with them. iEGOPODIUM, in Botany, Small Wild Angelica, Goatwort, Goatsfoot. iEGOSPOTAMOS, in Ancient Geography, a river in the Thracian Chersonesus, falling with a south-east course into the Hellespont, to the north of Sestos; with a town, and a station or road for ships, at its mouth. Here the Athen¬ ians under Conon, through the fault of his colleague Iso¬ crates, received a signal overthrow from the Lacedemon¬ ians under Lysander, which was followed by the taking of Athens, and put an end to the Peloponnesian war. 7EG YPTIAC UM, in Pharmacy, the name of several detergent ointments; as black, red, white, simple, and compound. 7EGYPTILLA, in Natural History, the name of a stone described by the ancients, and said by some authors to have the remarkable quality of giving water the colour and taste of wine. This seems a very imaginary virtue, as are indeed too many of those in former ages attributed to stones. The descriptions left us of this remarkable fossil tell us, that it was variegated with, or composed of, veins of black or white, or black and bluish, with sometimes a plate or vein of whitish red. The authors of these ac¬ counts seem to have understood by this name the several stones of the onyx, sardonyx, and cameo kind; all which we have at present common among us, but none of which possesses any such strange properties. 7EGYPTUS, in fabulous history, was the son of Belus, and brother of Danaus. AEINAUT7E, in Antiquity, ativavrcu, always mariners, a denomination given to the senators of Miletus, because they held their deliberations on board a ship, and never returned to land till matters had been agreed on. 7ELFRIC, an eminent ecclesiastic of the 10th century, was the son of an earl of Kent, and a monk of the Bene¬ dictine order in the monastery of Abingdon. In 963 he was settled in the cathedral of Winchester, under Athel- wold the bishop, and undertook the instruction of the youth of the diocese ; for which purpose he compiled a Latin-Saxon vocabulary, and some Latin colloquies. He JE M I also translated from the Latin into Saxon many of the historical books of the Old Testament. While he resided at Winchester he drew up Canons, which are a kind of charge to be delivered by the bishops to their clergy. He was afterwards abbot of St Albans, bishop of Wilton, and finally, in 994, translated to the-see of Canterbury. Here he had a hard struggle for some years in bravely defend¬ ing his diocese against the incursions of the Danes. He died in 1005, and was buried at Abingdon; but his re¬ mains were removed to Canterbury in the reign of Canute. Hilfric is held up as one of the most distinguished prelates of the Saxon church. His learning, for the times, was considerable, his morals pure, and his religious sentiments untainted with many of the corruptions of his age. Be¬ sides the works already mentioned, he translated two vo¬ lumes of Homilies from the Latin Fathers. TELIA, Capitolina, a name given to the city built by the emperor Adrian, a. d. 134, near the spot where the ancient Jerusalem stood, which he found in ruins when he visited the eastern parts of the Roman empire. A Ro¬ man colony was settled here, and a temple, in place of that of Jerusalem, was dedicated to Jupiter Capitolinus. Hence the name is derived, to which he prefixed that of his own family. TELIAN, Claudius, born at Praeneste, in Italy. He taught rhetoric at Rome, according to Perizonius, under the emperor Alexander Severus. He was surnamed MiXryXuaeog, Honey-mouth, on account of the sweetness of his style in his discourses and writings. He was like¬ wise honoured with the title of Sophist, an appellation in his days given only to men of learning and wisdom. He loved retirement, and devoted himself to study. He greatly admired and studied Plato, Aristotle, Iso¬ crates, Plutarch, Homer, Anacreon, Archilochus, &c. and, though a Roman, gives the preference to the writers of the Greek nation. His curious and entertaining work entitled Variae Historice has been frequently republished. The edition published at Amsterdam in 1731, by Gro- novius, cum notis variorum, consists of two 4to volumes. His treatise Be Natura Animalium has also been several times reprinted. A very useful edition, in all respects indeed the best, was published by Schneider, at Leipsic, in 1784, in 8vo. Besides the above, the collated edition of his works, published by Gesner, contains his Epistolce Rusticce. AELTERE, a town with 3973 inhabitants, in the ar- rondissement of Ghent, and province of East Flanders. TEL UR US, in Egyptian Mythology, the deity or god of cats; represented sometimes like a cat, and sometimes like a man with a cat’s head. The Egyptians had so superstitious a regard for this animal, that the killing of it, whether by accident or design, was punished with death; and Diodorus relates, that, in the time of extreme famine, they chose rather to eat one another than touch these sacred animals. AEM, Am, or Ame, a liquid measure used in most parts of Germany, but different in different towns. The aem commonly contains 20 vertils, or 80 masses: that of Hei¬ delberg is equal to 48 masses, and that of Wirtemberg to 160 masses. 7EMILILTS, Paulus, the son of Paulus TEmilius who was killed at the battle of Cannae. He was twice consul. In his first consulate he triumphed over the Ligurians, and in the second subdued Perseus, king of Macedonia, and reduced that country to a Roman province, on which he obtained the surname of Macedonicus. He returned to Rome loaded with glory, and triumphed for three days. He died 168 years before Christ. TEmilius, Paulus, a celebrated historian, born at Ve- Q* iE N I rona who obtained such reputation in Italy, that he was °' invited into France by the cardinal of Bourbon, in the reien of Louis XIL, in order to write the history of the ,is. kjmrg of France in Latin, and was presented to a canonry ’^in the cathedral of Paris. He died at Paris on the 5th of Mav 1539- His work entitled Be Rebus gestis Franco- rum was translated into French by Renard in 1581, and it has also been translated into Italian and German. 7EMOBOLIUM, in Antiquity, the blood of a bull or ram offered in the sacrifices, called taurobolia and criobolia; in which sense the word occurs in ancient inscriptions. TENSAS, in fabulous history, a famous Trojan prince, the son of Anchises and Venus. At the destruction of Troy, he bore bis aged father on his back, and saved him froin the Greeks; but, Being too solicitous about his son and household gods, lost his wife Creiisa in the escape. Landing in Africa, he was kindly received by Queen Dido ; but quitting her coast, he arrived in Italy, where he married Lavinia, the daughter of King Latinus, and de¬ feated Turnus, to whom she had been contracted. After the death of his father-in-law, he was made king of the Latins, over whom he reigned three years; but joining with the Aborigines, he was slain in a battle against the Tuscans. Virgil has rendered the name of this prince immortal, by making him the hero of his poem. TEneas Sylvius, Pope. See Pius II. TEN E A TO RES, in Antiquity, the musicians in an army, including those that played on trumpets, horns, &c. The word is formed from ceneus, on account of the brazen in¬ struments used by them. TENEID, the name of Virgil’s celebrated epic poem, devoted to celebrate the establishment of iEneas in Italy. TENGIA, one of the islands of the Archipelago. It lies in the bay of Engia, and the town of that name contains about 800 houses and a castle ; and near it are the ruins of a magnificent structure, which was formerly a temple. TENIGMA denotes any dark saying, wherein some well- known thing is concealed under obscure language. The word is Greek, Aiviyga, formed of aimndGai, obscure in- nuere, to hint a thing darkly, and of a/vog, an obscure speech or discourse. The popular name is riddle; from the Belgic raedcn, or the Saxon araethan, to interpret. Painted JEnigmas are representations of the works of nature or art, concealed under human figures, drawn from history or fable. A Verbal AEnigma is a witty, artful, and abstruse de¬ scription of any thing. In a general sense, every dark saying, every difficult question, every parable, may pass for an aenigma. Hence obscure laws are called cenigma- ta, juris. The alchemists are great dealers in the enig¬ matic language, their processes for the philosopher s stone being generally wrapt up in riddles: e. g. Fac ex mare et fcemina circulum, indc quadrangulum, hinc triangulum, fac circulum, et habebis lapidem philosophorum. F. Menestrier has attempted to reduce the composition and resolution of enigmas to a kind of art, with fixed rules and principles, which he calls the philosophy of (enigmatic images. The Suly'ect of an JEnigma, or the thing to be conceal¬ ed and made a mystery of, he justly observes, ought not to be such in itself; but, on the contrary, common, ob¬ vious, and easy to be conceived. It is to be taken either from nature, as the heaven or stars ; or from art, as paint¬ ing, the compass, a mirror, or the like. The Form of JEnigmas consists in the words which, whether they be in prose or verse, contain either some description, a question, or a prosopopoeia. The last kind are the most pleasing, inasmuch as they give life and action to things which otherwise have them not. To iE O L 173 TEolic. make an senigma, therefore, two things are to be pitched iEnigmas on which bear some resemblance to each other, as the sun " and a monarch, or a ship and a house; and on this re¬ semblance is to be raised a superstructure of contrarieties, to amuse and perplex. It is easier to find great subjects for senigmas in figures than in words, inasmuch as paint¬ ing attracts the eye and excites the attention to discover the sense. The subjects of senigmas in painting are to be taken either from history or fable : the composition here is a kind of metamorphosis, wherein, e. g. human figures are changed into trees, and rivers into metals. It is es¬ sential to aenigmas, that the history or fable under which they are presented be known to every body, otherwise it will be two aenigmas instead of one; the first of the history or fable, the second of the sense in which it is to be taken. Another essential rule of the aenigma is, that it only admits-of one sense. Every aenigma which is sus¬ ceptive of different interpretations, all equally natural, is so far imperfect. What gives a kind of erudition to an aenigma, is the invention of figures in situations, gestures, colours, &c. authorized by passages of the poets, the cus¬ toms of artists in statues, basso-relievos, inscriptions, and medals. As to the solution of aenigmas, it may be observed, that those expressed by figures are more difficult to explain than those consisting of words, because images may signify more things than words can; so that to fix them to a particular sense, we must apply every situation, sym¬ bol, &c. and without omitting a circumstance. As there are few persons in history or mythology without some particular character of vice or virtue, we are, before all things, to attend to this character, in order to divine what the figure of a person represented in a painting signifies, and to find what agreement this may have with the sub¬ ject whereof we would explain it. Thus, if Proteus be represented in a picture, it may be taken to denote incon¬ stancy, and applied either to a physical or moral subject, whose character is to be changeable, e. g. an almanack, which expresses the weather, the seasons, heat, cold, storms, and the like. The colours of figures may also help to unriddle what they mean ; white, for instance, is a mark of innocence, red of modesty, green of hope, black of sor¬ row, &c. When figures are accompanied with symbols, they are less precarious ; these being, as it were, the soul of amigmas, and the key that opens the mystery of them. AENIGMATOGRAPHY, or iENiGMATHOLOGY, the art of resolving or making aenigmas. AENITHOLOGIUS, in Poetry, a verse of two dactyls and three trochaei; as Prcelia dir a placent truci juventw. TEOLIiE Insulas, now Isoli Lipari, in Ancient Geo¬ graphy, seven islands situated between Sicily and Italy; so called from iEolus, who reigned there about the time of the Trojan war. The Greeks call them Rephcestiades ; and the Romans Vulcanice, from their fiery eruptions. They are also called Liparceorum Insulce, from their prin- ■ cipal island Lipara. Dionysius Periegetes calls them nXura/, because circumnavigable. iEOLIAN Harp. See Acoustics, and Harp. iEOLIC, in a general sense, denotes something belong¬ ing to iEolis. iEoLic, or TEolian, in Grammar, denotes one ot the five dialects of the Greek tongue. It was first used in Bceotia, whence it passed into iEolia, and was that which Sappho and Alcmus wrote in. The .Eolic dialect general¬ ly throws out the aspirate or sharp spirit, and agrees in so many things with the Doric dialect, that the two are usually confounded together. The Aolic digamma is a name given to the letter P, which the JEolians used to prefix to words beginning with 174 iE O N ^Eolic ^Eon. vowels, as Yotvog for o/vog; also to insert between vowels, as oF/j for o/g. JEolic Verse, in Prosody, a verse consisting of an iam¬ bus or spondee; then of two anapests, separated by a long syllable ; -and, lastly, of another syllable : such as, O stelliferi conditor orbis. ihis is otherwise called eulogic verse ; and, from the chief poets who used it, Archilochian and Pindaric. iEOLIPILE, in Hydraulics, is a hollow ball of metal, generally used in courses of experimental philosophy, in order to demonstrate the possibility of converting water into an elastic steam or vapour by heat. The instrument, therefore, consists of a slender neck or pipe, having a narrow orifice inserted into the ball by means of a shoulder¬ ed screw. This pipe being taken out, the ball is filled almost full of water, and the pipe being again screwed in, the ball is placed on a pan of kindled charcoal, where it is well heated, and there issues from the orifice a vapour, with prodigious violence and great noise, which continues till all the included water is discharged. The stronger the fire is, the more elastic and violent will be the steam; but care must be taken that the small orifice of the pipe be not by any accident stopped up, because the instru¬ ment would in that case infallibly burst in pieces, with such violence as might greatly endanger the lives of the persons near it. Another way of introducing the water is to heat the ball red-hot when empty, which will drive out almost all the air ; and then by suddenly immerging it in water, the pressure of the atmosphere will force in the fluid, till it is nearly full. Descartes and others have used this instrument to account for the natural cause and gene¬ ration of the wind : and hence it was called JEolipila : q. d. ])ila Mali, the ball of fEolus, or of the god of the winds. FEOLLS, or Alolia, in Ancient Geography, a country of the Hither Asia, settled by colonies of fEolian Greeks. Taken largely, it comprehends all Troas and the coast of the Hellespont to the Propontis, because in those parts there were several iEolian colonies. In a more limited sense it is applied to the district between Troas to the north and Ionia to the south. The people are called JEoles or JEolii. 7EOLUS, in Heathen Mythology, the god of the winds, was said to be the son of Jupiter by Acasta or Sigesia, the daughter of Hippotas; or, according to others, the son of Hippotas by Meneclea, daughter of Hyllus, king of Lipara. He dwelt in the island Strongyle, now called Strombolo, one of the seven islands called fEolian, from their being under the dominion of fEolus. Others say that his residence was at Rhegium, in Italy ; and others, again, place him in the island Lipara. He is represented as haying authority over the winds, which he held en¬ chained in a vast cavern, to prevent their continuing the devastations they had been guilty of before they were put under his direction. fEON, a Greek word, properly signifying the age or duration of any thing. b fEox, among the followers of Plato, was used to signify any virtue, attribute, or perfection: hence they repre- sented the deity as an assemblage of all possible mons, and called him pleroma, a Greek term signifying fulness. The Valentinians, who, in the first ages of the church, blended the conceits of the Jewish cabalists, the Platonists, and the Chaldean philosophers, with the simplicity of the Christian doctrine, invented a kind of Theogony, or Gene- alogy of Gods (not unlike that of Hesiod), whom they called by several glorious names, and all by the general appellation of Aions : among which they reckoned Zw>j, life; Aoyog, word; Movoyovqs, only-begotten; UXriPojga, fulness; and many other divine powers and emanations, iE P I amounting in number to thirty; which they fancied to be successively derived from one another, and all from one self-originated deity, named Bythus, i. e. profound m un- 1 fathomable ; whom they called likewise, the most high andf* ineffable father. AiORA, among ancient writers on medicine, is used for gestation ; which sort of exercise was often prescribed by the physicians of those days. Other exercises consisted principally in the motion of the body ; but in the ceora the limbs were at rest, while the body was carried about and moved from place to place, in such a manner as the phy. sician prescribed. It had therefore the advantage of ex¬ ercise, without the fatigue of it. This exercise was pro¬ moted several ways ; sometimes the patient was laid in a sort of hammock, supported by ropes, and moved back- ward and forward ; sometimes his bed ran nimbly on its feet; and sometimes he was carried in a litter, in a boat or ship, or on even ground in a chariot. Asclepiades was the first who brought gestation into practice, which was used as a means to recover strength after a fever, &c. iEPINUS, Francis Ulrich Theodore, eminent in the mathematics, and in natural philosophy, was born at Rostock in Lower Saxony in 1724, and died at Dorpt in Livonia in 1802. We regret that our means of informa¬ tion do not enable us to communicate any particulars in regaid to his personal history; but we shall give some account of his contributions to science; and these, after all, form the most interesting memorials of a philosopher’s life! The work by which he is best known is entitled Ten- tamen Theoriai Electricitatis et Magnetismi, published at Petersburg in 1759. It appeared under the sanction of the Imperial Academy, to which the theory had been in part communicated ; and it is said on the title-page to be Instar Supplementi Comment. Acad. Petropolitance. The work indeed merited this distinction, as being the first systematic and successful attempt to apply mathematical reasoning to the subjects of electricity and magnetism. Already the theory of Franklin with regard to the for- mer was very generally received, and was supposed to affoi d a satisfactory explanation of the phenomena. But though it seemed sufficient for this purpose in the common and somewhat loose manner in which the matter had hitherto been treated, it was not certain that the same would hold when the conclusions were accurately and mathematically deduced. To apply this test was what /Epinus undertook, and what he has executed in a manner very satisfactory and complete. He has treated very ful- ly, and perhaps has nearly exhausted, what may be called the statics of electricity and magnetism, or the equilibrium of their forces. A great field yet remains, where the mo¬ tion of the electric fluid is to be considered, and its dis- tiibution over the surfaces of bodies of a given figure; where greater difficulties are to be encountered, and where the latest improvements of the integral calculus in the hands of Laplace and Poisson have begun to be applied, ihe investigations of Aipinusin their own department led to very satisfactory results, and the exact agreement be¬ tween them and the phenomena actually exhibited was extensively observed. Notwithstanding this agreement, we cannot consider the theory of positive and negative electricity as being yet sufficiently established. Though the assumption on which it is founded appear very simple at first, it is found more complex on a nearer inspection. I he assumption is, that a fluid resides in the surfaces of all the bodies termed electrics, which is highly elastic, and strongly attracted, at the same time, by the particles of the body; and that while this fluid remains equally diffused over t le suiface of the body, no phenomenon whatever gives any information of its existence. By certain mechanical opera- M P I £ ip. t;ons> however, the equilibrium of this fluid maybe destroy- kWed; the fluid may be accumulated at one end, or on one side of a body, and entirely withdrawn from the opposite. It is when an electric is brought into this state that it exhibits the phenomena of electricity, between which and the cal¬ culus instituted on the suppositions just laid down, jEpinus has everywhere remarked the most exact agreement. One „reat difficulty, however, still remains : the negative ends of two electrified bodies repel one another just as much as the ends which are reckoned positive. But such an effect cannot result from the mere absence of a substance : when the electric fluid is withdrawn, if repulsion still continue, it must arise from the mutual action of the particles of the body itself. Thus it would appear, that, in the absence of the electric fluid, the tendency of the particles of matter is to repel one another. This is an essential part of the theory; and it is not accurate to say, that the doctrine of Franklin or iEpinus supposes no more than the existence of an elastic fluid diffused over the surfaces, and strongly attracted by the particles, of bodies. It supposes, besides, that those particles, in the absence of this fluid, mutually repel one another. This not only takes away from the simplicity of the hypothesis, but it is obviously a very un¬ natural, not to say a contradictory supposition ; because, when the electric matter is removed, how comes it to pass that the particles of the body, notwithstanding their mu¬ tual repulsion, still cohere together as firmly as before ? This difficulty is acknowledged by fEpinus himself; but it would seem that the theory had taken a strong hold of his mind before he was aware of this consequence from it, so that he became by degrees reconciled to a supposition which appeared to him at first not a little incongruous. This must not surprise us: it is not always that, even among philosophers, we meet with the candour, or perhaps we should say the courage, with which Newton suspended his belief in his own great discovery, the principle of uni¬ versal gravity, as long as the erroneous opinion then exist¬ ing about the magnitude of the earth made the moon’s motion in her orbit appear inconsistent with the descent of falling bodies. Another remark, made by AEpinus himself, involves in it a difficulty which should have induced him to view his theory with considerable diffidence. Though he considers the difference of the two electricities to be the same as between excess and defect, or to consist in this, that the fluid which is deficient in the one part is in excess in the other, he admits that no phenomenon points out on which side the excess, or on which the defect lies. This is a strong indication that the difference is not of the kind sup¬ posed. We are not left at a loss to tell whether cold is the absence of a substance which we call heat, or heat the absence of a substance which we call cold. If there were just as much reason for asserting the one of these propo¬ sitions as the other, one would certainly be inclined to re¬ ject both. The same should be done with respect to elec¬ tricity and magnetism. The investigations of iEpinus, however, are by no means rendered useless, even if the theory of positive and nega¬ tive electricity, or of positive and negative magnetism, be exchanged for that of two elastic fluids, each attracting the other, and both attracted by the particles of bodies. Most of his investigations may be easily accommodated to this supposition, and, therefore, they are, fortunately for themselves and for their author, of a more permanent na¬ ture than the principles from which they were deduced. It is to be added to this, that iEpinus was the first who saw the affinity between electricity and magnetism in its full extent, and perceived the light that these two mutu¬ ally cast on one another. He instituted a regular series iE P I 175 of experiments on the nature of the tourmaline, on which -®pinus. he wrote a small treatise, published in 1762. He is to be' regarde'd also as the inventor of the condenser of electri¬ city, and of the electrophorus, of which he gave the com¬ plete theory. A very excellent view of the theory of ASpinus was published at Paris by M. Hauy in 1787, in 8vo. The same author has, however, -adopted the theory of the two fluids in his own treatise, Lemons de Physique. There is a remarkable coincidence between vEpinus’s work on elec¬ tricity and magnetism, and that of Mr Cavendish, given in the Philosophical Transactions for 1771, p. 584. The prin¬ ciples from which they set out, and the conclusions at which they arrive, are in a great measure the same. It appears, however, quite certain, that Mr Cavendish knew nothing of the work of the Russian philosopher till his own was completed. His mode of proceeding is more geome¬ trical, and in some parts he has gone farther. The researches of iEpinus were not confined to the subjects now mentioned, but extended to most of the branches of natural philosophy. Beside the treatise on the tourmaline, he published, in 1762, a work, in 4to, On the distribution of heat at the surface of the earth ; a work which, though translated into French, has hardly, we believe, made its way into this country, and of which we are therefore unable to speak from our own knowledge. He is also the author of many valuable memoirs on dif¬ ferent subjects in pure mathematics, in astronomy, mecha¬ nics, optics, meteorology, contained in the 7th, 8th, 9th, 10th, and 12th volumes of the Novi Commentarii Petro- politance, and in the volumes of the Berlin Memoirs for 1755, 1756. In a memoir contained in the last of these, is the first account of his experiments on the tourmaline, which were conducted with great accuracy and judgment, and do honour to the author as a man of a sound and philosophical understanding, well instructed in the true principles of inductive investigation. Indeed, notwith¬ standing the objections we have made to his theories of electricity and magnetism, we must acknowledge that this is the general impression produced by the perusal of his works. He appears to have been well acquainted with practical astronomy, and sometimes to have had the charge of the imperial observatory. He made improve¬ ments on the micrometer and the reticulum, and wrote a memoir on the effects of parallax in the transit of a planet over the sun ; a difficult subject, and one rendered at that time (1764) peculiarly interesting, on account of the tran¬ sit of Venus which was just past, and that which was soon expected. (Novi Com. Pet. tom. x. p. 433.) In the same volume he has a memoir on the subject of accidental colours, which at that time had hardly been treated of by any author but Buffon ; and another on the affinity between electricity and magnetism. In the 12th volume he notices, we believe for the first time, the electric property of the Brazilian emerald. He was not aware that this emerald is in reality the green tourmaline (Brogniart, tom. i. p. 418.) ; a variety of that mineral on which he had already exercised his ingenuity with so much success. It is rare, in an advanced state of science, to have the satisfaction of making a new discovery with regard to a subject quite elementary, and one that has been long a subject of attention. This, however, happened to iEpinus with respect to the lever, and to the simplest kind of le¬ ver—that which has equal arms; of which he has demon¬ strated a new property, in the 8th volume of the Com¬ mentaries above referred to. It is this :—If a lever with equal arms be acted on at its opposite ends by forces in a given ratio to one another, and having their directions parallel to straight lines given in position; and if these 176 iE R A A E R ^quime- forces be resolved each into two, one at right angles to lium - /Rrarium. the lever, and the other in the direction of it; in the case of equilibrium, the sum of the two forces, having the same ^ direction with the lever, will be the greatest possible. This theorem, remarkable for its simplicity, and for illustrating the connection between the equilibrium of bodies, and certain problems concerning the maxima or minima of variable quantities, occurred when he was pursuing some of his inquiries concerning magnetism. He seems not to have been very fortunate, however, in his investigation, which is more complex than is necessary, as the proposi¬ tion admits of a geometrical demonstration remarkable for its simplicity. (n.) iEQUIMELIUM, in Antiquity, a place in Rome where stood the house of Spurius Melius, who, by largesses cor¬ rupting the people, affected the supreme power. Refusing to appear before the dictator Cincinnatus, he was slain by Servilius Ahala, master of the horse ; his house was razed to the ground, and the spot on which it stood was called Area JEquimelii. (Livy.) fERA, in Chronology, a fixed point of time from whence any number of years is begun to be counted. It is sometimes also written in ancient authors Era. The origin of the term is contested, though it is general¬ ly allowed to have had its rise in Spain. Sepulveda sup¬ poses it formed from A. ER. A. the notas or abbreviatures of the words annus erat Augusti, occasioned by the Spa¬ niards beginning their computation from the time their country came under the dominion of Augustus, or that of receiving the Roman calendar. This opinion, however ingenious, is rejected by Scaliger, not only on account that in the ancient abbreviatures A never stood for annus, un¬ less when preceded by V for vixit; but that it seems im¬ probable they should put ER for erat, and the letter A, without any discrimination, both for annus and Augustus. Vossius nevertheless favours the conjecture, and judges it at least as probable as either that of Isidore, who de¬ rives ara from ces, the tribute-money wherewith Augustus taxed the world ; or that of Scaliger himself, who deduces it likewise from as, though in a different manner. JEs, he observes, was used among the ancients for an article or item in an account; and hence it came also to stand for a sum or number itself. From the plural cera, came by corrup¬ tion ara, arum, in the singular; much as Ostia, Ostiam, the name of a place, from Ostia, the mouths of the Tiber. The difference between the terms ara and epoch is, that the aeras are certain points fixed by some people or na¬ tion, and the epochs are points fixed by chronologists and historians. The idea of an sera comprehends also a cer¬ tain succession of years proceeding from a fixed point of time, and the epoch is that point itself. Thus, the Chris¬ tian aera began at the epoch of the birth of Jesus Christ. iERARIUM, the treasury or place where the public money was deposited amongst the Romans. JErarium Ilithya, or Jiinonis Lucina, was where the moneys were deposited which parents paid for the birth of each child. JErarium Privatum was the emperor’s privy purse, or the place where the money arising from his private patri¬ mony was deposited. JErarium Sanctius contained the moneys arising from the twentieth part of all legacies: this was kept for the extreme necessities of the state. JErarium Vicesimarum, the place where the money arising from the taxes levied from foreign countries was laid up ; so called because it most commonly consisted of a twentieth part of the produce. There are several other treasuries mentioned in history, as the JErarium Juventutis, Veneris, &c. The temple of Saturn was the public treasury of Rome, either because Saturn first taught the Italians to coin money, or, which is most likely, because this temple was the strongest and most secure, and therefore the fittest place for that purpose. JErarium differs from Fiscus, as the first contained the public money, the second that of the prince. The two are however, sometimes indiscriminately used for each other! fERARIUS, a name given by the Romans to a degrad! ed citizen, who had been struck off the list of his century. Such persons were so called, because they were liable to all the taxes (ara), without enjoying any of its privileges. The ararii were incapable of making a will, of inheriting of voting in assemblies, or of enjoying any post of honour or profit; in effect, they were only subject to the burdens, without the benefits of society; yet they retained their freedom, and were not reduced to the condition of slaves. To be made an ararius was a punishment inflicted for some offence, and reputed one degree more severe than to be expelled a tribe, tribu moveri. AHrarius was likewise an officer instituted by Alexan¬ der Severus, for the distribution of the money given in largesses to the soldiery or people. fERARius was also used for a person employed in coin¬ ing or working brass. These are sometimes called ararii fusores. At other times, ararius is distinguished from fusor ; the former answering to what we now call copper¬ smiths, the latter to founders. fERARius was also applied to a soldier who receives pay. AERIA, or Eeria, in Ancient Geography, the ancient name of Egypt. The scholiast on Apollonjus Rhodius says, tha.t not only Thessaly, but Egypt, was called Higm by the Greeks, which Eusebius also confirms ; and hence Apollinarius, in his translation of the 114th Psalm, uses it for Egypt. Hesychius applies this name to Ethiopia. AERIANS, in Church History, a branch of Arians, who to the doctrines of that sect added some peculiar dogmas of their own; as, that there is no difference between bishops and priests,—a doctrine maintained by many mo¬ dern divines, particularly of the presbyterian and reform¬ ed churches. The sect received its denomination from Aerius, an Arminian priest of the fourth century. Flos iERIS, among alchemists, small scales procured from copper melted by a strong heat: it is sometimes used for aerugo or verdigris. AERNEN, a market town near the river Rhone, in the canton of Walles or Valais, in Switzerland, in the district of Sambs. It has a state-house and other good buildings, and is the seat of justice for the district. AEROGRAPH Y, from cojg, air, and ygoupu, I describe; a description of the air or atmosphere, its limits, dimen¬ sions, properties, &c. AEROLITE, a term recently, but perhaps improperly, applied to those singular substances commonly called Meteoric Stones. AEROMANCY, a species of divination performed by means of air, wind, &c. AEROME TRY, the science of measuring the air. It comprehends not only the doctrine of the air itself, con¬ sidered as a fluid body, but also its pressure, elasticity, rarefaction, and condensation. But the term is at present not much in use, this branch of natural philosophy being more frequently called Pneumatics. AERONAU1ICA, from ajjff, and munxog, derived from vccvg, ship ; the art of sailing in a vessel or machine through the atmosphere, sustained as a ship in the sea. See Aeronautics. AEROPH^LACEA, a term used by naturalists for caverns or reservoirs of air, supposed to exist in the bowels of the earth. l\ -rim /,-Aj 177 AERONAUTICS. Uro u. TN every stage of society men have eagerly sought, by the tk I- combination of superior skill and ingenuity, to attain - those distinct advantages which nature has conferred on radl the different tribes of animals, by endowing them with a ;SC°U peculiar structure and a peculiar force of organs. The rna a’ rudest savage learns from his very infancy to imitate the swimming of a fish, and plays on the surface of the water with an agility and a perseverance which seem to decline with the advancement of civilisation. But an art so con¬ fined in its exercise, and requiring such a degree of bo¬ dily exertion, could not be considered of much avail. It was soon, perceived, that the fatigue of impulsion through the water could be greatly diminished, by the support and floating of some light substance. The trunk of a tree would bear its rude proprietor along the stream; or, hol¬ lowed out into a canoe, and furnished with paddles, it might enable him even to traverse a river. From this simple fabric, the step was not great to the construction of a boat or barge, impelled by the force of oars. But it was a mighty stride to fix masts and apply sails to the vessel, and thus substitute the power of wind for that of human labour. The adventurous sailor, instead of plying on the narrow seas, or creeping timidly along the shore, could now launch with confidence into the wide ocean. Navigation, in its most cultivated form, may be fairly re¬ garded as the consummation of art, and the sublimest triumph of human genius, industry, courage, and perse¬ verance. Having by his skill achieved the conquest of the waters that encompass the habitable globe, it was natural for 'man to desire likewise the mastery of the air in which we breathe. In all ages, accordingly, has ingenuity been tortured in vain efforts at flying. The story of Icarus tes¬ tifies how fatal such daring attempts had generally proved to their projectors. Trials made with automatons, though less liable to risk and danger, were yet equally fallacious. Archytas, a most eminent Greek geometer and astrono¬ mer, who perished by shipwreck on the coast of Calabria, was believed by his admiring contemporaries to have con¬ structed an artificial dove, which, by the action of a sys¬ tem of internal springs, wafted itself through the air. If such a piece of mechanism was ever made, we may be sure that its flight was really produced, as in the scenes of the opera, by means of invisible strings or wires. - So thoroughly were the ancients convinced of the im¬ possibility of men being able to fly, that they ascribed the absolute rule of the sky to divinities of the first order. The supreme Jupiter alone reposed on his empyreal throne, far above the heights of Olympus; and to him was it given, from the region of the clouds, to point the winged lightning, and to hurl the flaming thunderbolt. On spe¬ cial missions he dispatched Mercury, as his messenger, through the wide range of atmosphere. The oriental nations, from whom we have borrowed the greater part of our vulgar mythology, likewise committed such journeys to certain genii or ministering spirits. But the glowing visions of the East received a darker tinge from the cha¬ racter and climate of our Gothic ancestors. The arch¬ fiend himself was, at no very distant period, firmly be¬ lieved to have the especial control of the air, and to career in the whirlwind and impel the howling tempest. Those wretched creatures whom the unfeeling credulity of our ancestors, particularly during the prevalence of religious fanaticism, stigmatized and murdered under the denomi- vol. n k„“ iniujj, nation of witches, were supposed to work all their enchant- Aeronau- ments, to change their shapes at will, and to transport i tics- themselves through the air with the swiftness of thought, by a power immediately derived from their infernal masr ter. At a period somewhat earlier, every person in pos¬ session of superior talents and acquirements was believed to deal in magic, and to perform his feats of skill chiefly through the secret aid granted him by the prince of darkness. In spite of the incurable perverseness of his conduct, it must be confessed that the devil has always had the credit of retaining some little inclination to assist the efforts of genius. During the darkness of the middle ages, every one at and to ma- all distinguished by his knowledge in physics was gene-gicians. rally reputed to have attained the power of flying in the air. Our famous countryman Friar Bacon, among other dreams engendered in his fervid brain, has not scrupled to claim the invention of that envied and transcendent art. To these pretensions the credulity and indulgent admiration of some authors have lent more credit than they really deserved. Any person who will take the trouble to examine the passages of Bacon’s obscure though ponderous works, must soon be convinced, that the pro¬ positions advanced by him are very seldom founded on reality, but ought rather to be considered as the sportive illusions of a lively and teeming fancy. Albertus Magnus, who lived about the same period, and was esteemed in Germany as a perfect prodigy, pretended also to the art of flying. More than a century afterwards, John Muller of Kbnigsberg, and thence styled Regiomontanus, one of the chief restorers of genuine mathematical learning in Europe, was reported by some writers of note to have, like Archy¬ tas, fashioned an artificial dove, which displayed its wings, and flew before the emperor Charles V. at his public entrance into Niiremburg. But, unfortunately for the veracity of the story, Regiomontanus died in early life, full sixty years before that visit took place. While the belief in necromancy prevailed, such tales Dark fea_ assumed colours of the most lurid hue. Fiery dragons, tures of created by infernal machination, were imagined to rush that art. impetuous through the sky, vomiting flames, and widely scattering the seeds of pestilence. Grave writers, in those benighted ages, even ventured to describe the me¬ thod of imitating the composition of such terrific monsters. A mass of large hollow reeds were to be disposed and bound together, then sheathed completely in skin, and smeared over with pitch and other inflammable matters : this light and bulky engine, partially set on fire, and launched in the thickest darkness into the air, might be sufficient, when borne along by the force of the wind, to strike the ignorant populace with affright and horror. But such spectacles would come to lose their terrors by repeated failure and the insensible progress of knowledge. So late as the year 1750, a small Catholic town in Swabia was almost entirely burnt to ashes by an unsuccessful expe¬ riment of that sort, instigated, and probably directed, no doubt for the edification of their flock, by the lowest or¬ der of priests. It was attempted to represent the effigy of Martin Luther, whom the monks firmly believe to be the very imp of Satan, under the form of a winged serpent, furnished with all the requisite appendages of a forked tail and hideous claws. Unluckily for the skdl of the machinist, this phantom directly fell against the chimney of a house, to which it set fire and the flames spreading furiously in AERONAUTICS. Later at¬ tempts at flying. Impossibi¬ lity of fly. ing first demon¬ strated by Borelli. every direction, the people had soon cause to lament bit¬ terly their intemperate zeal. The scheme of flying in the air, which men of the first genius had once entertained, appears to have gradually descended to a lower class of projectors. Those who afterwards occupied themselves with such hopeless at¬ tempts, had commonly a smattering of mechanics, with some little share of ingenuity, but wrought up by exces¬ sive conceit. In the beginning of the sixteenth century, an Italian adventurer visited Scotland, during the reign of James IV.; and being a man of some address, and at the same time a pretender to alchemy, he contrived to insinuate himself into the favour of that gay and needy prince, by holding out hopes of augmenting his scanty treasury by the acquisition of the philosopher’s stone. He was collat¬ ed by royal favour to the abbacy of Tungland in Galloway; but not having succeeded in creating artificial riches, he resolved, in the height of his enthusiasm, at once to gra¬ tify and astonish the courtiers, by the display of a feat still more extraordinary. Having constructed a set of ample wings, composed of various plumage, he undertook, from the walls of Stirling Castle, to fly through the air to France. This experiment he had actually the folly or hardihood to try; but he soon came to the ground, and broke his thigh-bone by the violence of the fail. For his unlucky failure, however, the abbot had the dexterity to draw a very plausible excuse from the wretched sophistry, termed science in that age. “ My wings,” said the artful Italian, “ were composed of various feathers ; among them were the feathers of dunghill fowls, and they, by a certain sympathy, were attracted to the dunghill; whereas, had my wings been composed of the feathers of eagles alone, the same sympathy would have attracted them to the re¬ gion of the air.” This anecdote has furnished to Dunbar, the Scotish poet, the subject of one of his rude Satires. A century afterwards, Fleyder, rector of the grammar- school at Tubingen, entertained, in 1617, the worshipful magistrates of that city with a lecture on the art of flying, which he published at the lapse of eleven years, yet pru¬ dently contented himself with barely explaining his theory. A poor monk, however, ambitious to reduce this theory into practice, having provided himself with spacious wings, took his flight from the top of a high tower; but encoun¬ tering a cross wind, his machinery misgave, and falling precipitously to the ground, he broke both his legs, and perished miserably. An accident of a similar kind is re¬ lated to have happened not long since near Vienna. The impossibility of rising, or even remaining suspend- ■ ed in the air, by the action of any machinery impelled by human force, was first demonstrated by Borelli, a most eminent Italian mathematician and philosopher, who lived in the fertile age of discovery, and was thoroughly ac¬ quainted with the true principles of mechanics and pneu¬ matics. In his celebrated and excellent work De Motu Animalium, published in 1670, he showed, by accurate calculation, the prodigious force which the pectoral mus¬ cles of birds must exert and maintain. The same princi¬ ples, applied to the structure of the human frame, proved how very disproportionate was the strength of the cor¬ responding muscles in man. It is not, therefore, the mere difficulty of contriving and combining machinery which should perform the peculiar motions of wings, that has rendered all attempts of the kind futile, but the utter want of adequate force in the human body to give such impulsion to those extended vanes as would be necessary for supporting so great a weight in the thin medium of the atmosphere. Having found by experience the impossibility, from any application of inherent strength, of ascending into the atmosphere, it* was natural for men of ardent minds, " who still pursued that dazzling project, to look for someMA extraneous aid among the varied powers of the elements. The notions entertained by the ancients respecting theC 4 composition of the world might have suggested importantg' il hints for realizing the scheme of aerial navigation. The11 °ft four elements—earth, water, air, and fire or ether, ar ranged according to their several qualities and tendencies, were supposed to constitute this universal frame. Earth being heavy and inert, occupies the centre of the system and above it flowed the waters; air, from its lightness rose upwards, and invested the globe with an atmosphere; while the diffuse ethereal substance soared, by its extreme buoyancy, to the celestial regions, and filled with splen¬ dour their pure expanse. Every portion of these distinct elements, if transported from its place, was conceived as having a natural and constant appetency to return to its original situation. Earth and water sink downwards by their gravity, while air and fire, endued with an opposite principle, as invariably rise to the higher spaces. A por¬ tion of fire, joined to water or to air, communicates, in a corresponding degree, its levity, or disposition to ascend. Thus, warm air always rises ; water, subdued by excessive heat, flies upwards in the form of vapour; and the volatile parts of inflamed bodies are borne to the sky in smoke. The first person that seems to have formed a just idea Id of the principle on which a balloon could be constructed® was Albert of Saxony, a monk of the respectable order of^ ft St Augustin, who lived in the fourteenth century, andjj’1 w . — J7 and! wrote a learned commentary on the physical works of^ Aristotle. Since fire is more attenuated than air, and of floats above the region of our atmosphere, this ingenious person conceived that a portion of such ethereal substance, inclosed in a light hollow globe, would raise it to a cer¬ tain height, and keep it suspended in the sky. But the same philosopher rightly subjoined, that a greater mixture of air introduced into the balloon, by rendering this heavier than before, would cause it to descend proportionally, in the same way precisely as water admitted through the seams of a ship makes the vessel to sink in the ocean. It is evident that nothing was wanted for completing Montgolfier’s discovery, but to carry those fine views into execution. Ihe ideas of Albert of Saxony were long afterwardsam zealously embraced by Francis Mendoza, a Portuguese6^ Jesuit, who died at Lyons in the course of a tour through ^ France in 1626, at the age of 46. He maintained that the combustible nature of fire was no real obstacle to its application in balloons, since its extreme levity, and the exclusion of the air, would hinder it from supporting in¬ flammation. Casper Schott, a Jesuit likewise, pursued am more soberly the same speculation in Germany. He^ stated that no air of these lower regions is ever light enough to produce an ascent, and that the lucid ethereal matter which swims above our atmosphere is alone fit¬ ted for aerial navigation. Were any superhuman power, therefore, to bring down a store of that buoyant substance, to be inclosed in a hollow ball of wood or thin lead, the vessel, being furnished with a rudder and sails, might then, he conceived, boldly navigate the sky. Similar notions have been renewed at different times.Bh They were likewise often blended with the alchemical"’’; tenets so generally received in the course of the fifteenth, sixteenth, and part of the seventeenth centuries. Con- 10 ceiving with the ancients that the dew which falls during the night is of celestial origin, and shed by the stars, speculative men still imagined this pure humidity to be drawn up again to the heavens by the sun’s rays in the AERONAUTICS. 179 ,auu Lgr.au- heat of the day. Many persons, imbued with the wretch- ’ ti. ed learning of that age, had the simplicity to believe that ^'^an egg-shell filled with the morning dew, and placed at the foot of a ladder leaning against the roof of a house, would, as the day advanced, spontaneously rise along the tv hi iicalbars, and mount to the chimney-tops. This whimsical rojt s offancy is confidently related as an observed fact by Father 'athi Lauretus Laurus. “ Take,” says he, very gravely, “ a goose egg, and, having filled it with dew gathered fresh in the morning, expose it to the sun during the hottest part of the day, and it will ascend, and rest suspended for a few moments.” To perform the experiment on a greater scale, however, he proposed to employ the largest swan’s egg, or a bag artificially prepared from the thinnest and lightest skin, into which, instead of dew, he would intro¬ duce the three alchemical elements, nitre, sulphur, and mercury; and he imagined that these active bodies, ex¬ panded and sublimed by the mere heat of the sun, must spring powerfully upwards. In this way he thought the dove of Archytas might be constructed. But the vision¬ ary priest had yet another scheme to advance for effect¬ ing the ascent of the automaton : he proposed to cram the cavity of the dove with highly condensed air ; and was so grossly ignorant of the principles of motion as to suppose that this imprisoned fluid would impel the machine in the same manner as wind does a sail. Should such a force be found not sufficiently efficacious, he finally recom¬ mended the application of fire; not, however, on account of its buoyant property, but because of the propulsive power which it exerts. To prevent the fire from con¬ suming the wooden machine, he recommends lining the inside with cloth of asbestos or other incombustible mate¬ rials ; and to feed and support steadily this fire, he sug¬ gested a compound of butter, salts, and orpiment, lodged in metallic tubes, which he imagined would at the same time heighten the whole effect, by emitting a variety of musical tones like an organ. Influenced by the same views, other authors, and par¬ ticularly the famous Cardan, have proposed, for aerial (1 Jury.ascents, to apply fire acting as in a rocket. Still later, but in the same country, Honoratus Fabry, penitentiary of the pope, and teacher in the gymnasium at Rome, who died about the end of the seventeenth century, de¬ scribed a huge apparatus, consisting of very long tin pipes, in which air was compressed by the vehement action of fire below. In a boat suspended from the machine, a man was to sit and direct the whole, by the opening or shut¬ ting of valves. The projects and vagaries of learned men about the misty period of the restoration of science were finely de r‘d'culed by Cyrano de Bergerac, a very witty and elo- iv -quent French writer, in a philosophical romance, entitled The Comical History of the States and Kingdoms in the Sun and Moon. This eccentric genius, born at Perigord in 1620, was noted for his impetuous temper and boiling courage. He spent his youth in dissipation and feats of arms; but afterwards, in riper life, he quitted the military profession, and betook himself to the study of poetry and philosophy, which he prosecuted with great ardour and success till he died, at the early age of 36. In his ro¬ mance, from which perhaps Swift borrowed the idea of Gulliver’s voyage to Laputa, Bergerac introduced a good deal of the Cartesian philosophy, then just coming into vogue; but lashed severely the pedantry and ignorance of various pretenders to science. To equip himself for per¬ forming the journey to the moon, the French traveller fastens round his body a multitude of very thin flasks fill¬ ed with the morning’s dew. The heat of the sun, by its attractive power exerted on the dew, raised him up to ilo. fa. ncf )f the middle region of the atmosphere ; where some of his Aerqnau- flasks happening unluckily to break, the adventurer sunk tlcs- again to the ground, and alighted in Canada. There constructed a new machine, acting by a train of wheels, with which he mounted to some height; but falling down, he had the misfortune to break his leg. He crept aside, in search of ox-marrow to compose a salve, with which he instantly healed his bruises; and returning again, he found his engine in the possession of some soldiers, who had fixed to it a number of sky-rockets. Replacing himself now in the car, he applied fire to the rockets, and darted upwards with inconceivable swiftness: the earth retired gradually from view, while the orb of the moon appeared proportionally to expand, till, approaching the sphere of her activity, he was borne softly along, and descended on the lunar surface into a most delicious and luxuriant grove. Here, of course, he met with angelic personages, endowed with every perfection of body and mind, and far exalted above the mean vices and the rancorous passions which poison and inflame the inhabitants of this blood¬ stained globe. In the conversations which Bergerac held with those supernal beings, he was informed that a na¬ tive of our planet, utterly disgusted at the crimes which pollute its “ sin-worn mould,” had once on a time provided himself with a pair of very large and thin metallic vessels, which he filled with smoke, and sealed in the light; and having attached himself below them, the buoyant power of the confined smoke carried him to the highest region of our atmosphere, where the attraction of the moon at length prevailing, drew him to her surface, while the great extent of the machinery, by opposing resistance, served to break the force of his fall. The moment, however, those slender capacious vessels were liberated from his weight, they rose again by the action of the smoke, till they reached a medium of the same density, and finally took their station in the bright fields of ether, where they form the constellation now called the Balance. In further discourse with his sublime-instructor, our romantic voyager was shown how to obtain the power of ascension from the loadstone. He was directed to take two magnets, each about a foot square, to roast them in the fire, to separate their impurities by solution, and thus concentrate their attractive virtue in a mere calx, which could be formed into a ball. Aided by such counsels, he now resolved to visit the sun. Mith much labour and perseverance he constructed a chest of very thin steel, six feet high and three feet wide; an icosahedron of crystal, the highest of all the regular solids, being fitted into the top, and the bottom having a small valve which opened outwards. Into this chest he shut himself, while the sun’s rays, concentrated and multiplied by reflection from the numerous facets of the crystal, heated the air intensely, and drove a great part of it out below; and he ascended rapidly towards the glorious luminary, breathing ecstaticly in divine light, which gleamed with the richest tints of enamelled gold and purple. But it would be fo¬ reign to our purpose to follow the rest of the narrative, which, though disguised and mingled with fantastic vi¬ sions, evidently contains the true principles of aeronautics. The most noted and elaborate scheme for navigating Lana’s the atmosphere was proposed by the Jesuit Francis Lana, scheme for in a book written in the Italian language, and printed at^vigating Brescia in 1670, with the aspiring title of Prodromo dell Arte Maestra. His project was to procure four copper balls of very large dimensions, yet so extremely thin, that, after the air had been extracted, they should become, in a considerable degree, specifically lighter than the sur¬ rounding medium. He entered into some calculations to prove that the buoyant power thus obtained would be 180 AERONAUTICS. Aeronau- fully adequate to produce the desired effect. Yet he ties. seems to have had only a slender knowledge of geometry, and but little acquaintance with the progress of physical science. For instance, he founds his computations en¬ tirely on the pneumatical discoveries of Galileo and Tori- celli, without making any reference to those important facts which the invention of the air-pump by Otto Gue¬ ricke had successively detected in the course of near 30 years. He assumes that air is 640 times lighter than water; that a cubic foot of water weighs 80 pounds, and . consequently that the weight of the same bulk of air is His calcu- an ounce and a half. If we rectify the estimate of Lana, lation.s. an(j reduce it to English measures, each of his copper balls had about 25 feet in diameter, with the thickness of only the 225th part of an inch, the metal weighing 365 pounds avoirdupois, while the weight of the air which it contain¬ ed must amount to 670 pounds, leaving, after a vacuum had been formed, an excess of 305 pounds, for the power of ascension. Those four balls would therefore rise to¬ gether into the atmosphere with a combined force of 1220 pounds, which was thought sufficient by the projector to transport a boat completely furnished with masts, sails, oars, and rudders, and carrying several passengers. To extract the air from their cavities, the method proposed was, to procure a Toricellian vacuum, by connecting each globe, fitted with a stop-cock, to a tube of at least thirty- five feet long; the whole being filled with pure water, and raised gently into a vertical position, the mass of liquid, exceeding the pressure of the atmosphere, would flow out, and subside to some point below the cock, which could then be shut. His at- Lana enumerates the different objections which might tempts to be urged against his scheme, and endeavours to answer answer ob- them. He thinks that the spherical and perfectly arched jections. form 0f sjieq 0p COpper WOuld, notwithstanding its ex¬ treme thinness, enable it, after the exhaustion was effect¬ ed, to sustain the enormous pressure of the external air, which, acting equally on every point of the surface, would rather tend to consolidate than to crush or tear the metal. As the atmosphere becomes always lighter in the upper regions, the machinery could only rise to a certain limit; and if this were found too high for easy breathing, the ascent could be regulated by opening occasionally the cocks to admit some air into the cavity of the balls, and thus increase their specific gravity. There seemed to him no very great difficulty in directing and impelling the aerial bark, by means of rudders, oars, and sails; but the objection was more serious on account of the hazards of tremendous shipwreck, from the violence of winds and tempests. Yet what most alarmed the insinuating Jesuit, and which he earnestly prays God to avert, was the dan¬ ger that would result, from the successful practice of the art of aeronautics, to the existence of civil government, and of all human institutions. No walls or fortifications could then protect cities, which might be completely sub¬ dued or destroyed, without having the power to make any sort of resistance, by a mere handful of daring as¬ sailants, who should rain down fire and conflagration from the region of the clouds. So sanguine was Lana, as to conceive that the very moderate sum of a hundred ducats would be sufficient to defray the expense of all this huge and delicate apparatus. But his poverty, fortunately, no doubt, for his credit as a man of learning, prevented him from proceeding further than mere speculation; and none of the foreign princes, who about that period often squandered, like gamesters, much of their wealth in the dark and chimerical search after the philosopher’s stone, seemed any way disposed to engage in the magnificent scheme of aerial navigation. The project of Lana appears to have in some degree / excited the attention of the learned, though it was at the same time very generally condemned. Hooke, Borelli k /\; Leibnitz, and Sturmius, examined it, and severely expos¬ ed its defects. Indeed, any person at all acquainted with actual experiment must see that it was absolutely im¬ practicable. Passing over other circumstances, the at¬ tenuated shell of copper, from its size and excessive thin¬ ness, could not have strength enough to support even its own weight, far less the slightest pressure of the atmo¬ sphere. The plate, however, that Lana has given of his whole combined apparatus appears very striking ;andafter Montgolfier’s discovery, it could not fail to attract a greater share of notice than it was otherwise entitled to claim. So late as the year 1755, and not very long before thefjUj final invention of balloons, a very fanciful scheme, yet onQ the grandest scale, for navigating the atmosphere, was pub¬ lished with most circumstantial detail, in a small pamphlet, by Joseph Galien, a Dominican friar, and professor of phi¬ losophy and theology in the papal university of Avignon. This visionary proposed to collect the fine diffuse air of the higher regions, where hail is formed, above the sum¬ mit of the loftiest mountains, and to inclose it in a bag of a cubical shape, and of the most enormous dimensions, extending more than a mile every way, and composed of the thickest and strongest sail-cloth. With such a vast machine, far outrivalling in boldness and magnitude the ark of Noah, it would be possible, he thought, to transport a whole army, and all their ammunitions of war. But we need not stop one moment to consider a project so per¬ fectly chimerical, which involves, besides, the erroneous supposition that the air of the upper regions is, indepen¬ dently of its diminished compression, essentially thinner and more elastic than the air below. It cannot fail to strike the reader, that the persons who have occupied themselves the most with attempts at aerial navigation, were all of them Catholic priests whether this pursuit is to be explained from their habits of seclusion and their ignorance of the affairs of real life, or from their familiar acquaintance with the relations of miracles and other legendary tales, which might lead them to see nothing very extraordinary in the art of flying through the air. The various schemes of that kind, pro¬ duced at different times, contain a few just principles, generally mixed up, however, with a large portion of ab¬ surdity. But very wide is the distance from such specu¬ lations to the real exhibition of the experiment itself. Some writers have stated that Lord Bacon first pub-( lished the true principles of aeronautics. This round as-id sertion we cannot help noticing, because it has really no I foundation, except in the propensity, fostered by indolence,0 which would gladly refer all theMiscoveries ever made to1' a few great names. They mistake, indeed, the character of Bacon, who seek to represent him as an inventor. His claim to immortality rests chiefly on the profound and comprehensive views which he took of the bearings of the different parts of human knowledge; for it would be difficult to point out a single fact or observation with which he enriched the store of physical science. On the contrary, being very deficient in mathematical learning, he disregarded or rejected some of the noblest discoveries made in his own time. We can find only two passages in Lord Bacon’s works which can be considered as referring to aeronautics, and they both occur in that collection of loose facts and in¬ conclusive reasonings which he has entitled Natural His¬ tory. The first is styled Experiment Solitary, touching l1 lying in the Air, and runs thus : “ Certainly many birds of good wing (as kites and the like) would bear up a good AE R ONAUTI C S. 181 ... „011 weieht as they fly; and spreading feathers thin and close, . . 1 Ji.U wt-* 11 1 Root* IITA Ci CTl'AQf' Trj the and in great breadth, will likewise bear up a great 'weight, being even laid, without tilting up on the sides. The further extension of this experiment might be thought upon.” This hint is not in fairness obnoxious to stric¬ ture,'since the ingenious Bishop Wilkins, twenty years afterwards, still believed that men could acquire the art of flying. Nor waS there any reason to despair, till Borelli at length demonstrated its absolute impos- sibility. The second passage is more diffuse, but less intelligible : it is styled Experiment Solitary, touching the Flying of unequal Bodies in the Air. “ Let there be a body of unequal weight (as of wool and lead, or bone and lead); if you throw it from you with the light end forward, it will turn, and the weightier end will recover to be for¬ wards, unless the body be over long. The cause is, for that the more dense body hath a more violent pressure of the parts from the first impulsion; which is the cause (though heretofore not found out, as hath been often said) of all violent motions: and when the hinder part moveth swifter (for that it less endureth pressure of parts) than the forward part can make way for it, it must needs be that the body turn over; for (turned) it can more easily draw forward the lighter part.” The fact here alluded to is the resistance that bodies experience in moving through the air, which depending on the quan¬ tity of surface merely, must exert a proportionally great¬ er effect on rare substances. The passage itself, however, after making every allowance for the period in which it was written, must be deemed confused, obscure, and un- philosophical. That a body must remain suspended in a fluid denser on bal- than itself, was first established by Archimedes, whose pro- ioojj positions in hydrostatics were further extended in modern times by Stevinus and other early mathematicians. But the principles on which a balloon could be made to rise in the atmosphere were scarcely understood till very long afterwards, when chemistry, near the latter part of the last century, had succeeded in ascertaining the properties of the different kinds of aeriform substances. The Greeks of the lower empire knew that air is greatly dilated by warmth; and Sanctorio, the ingenious medical professor at Padua, by applying this expansion, about the year 1590, to the construction of the thermometer, had hap¬ pily placed it in a strong light. His countryman Borelli remarked, almost a century afterwards, that a heated iron or a burning taper brought near one of the scales of a well-poised balance, by exciting a vertical current, will cause it to mount up with force,—a fact which affords the only true explication of the numerous experiments of Buffon with the weighing of red-hot balls, whose regular and constant results appeared to that eloquent philosopher to exhibit a conclusive demonstration of the actual pon¬ derability of heat. Yet warm air, alone and unassisted, has still no very great power of ascension. The buoyancy communicated to that fluid by the distensible vapour of water and other more volatile liquids is in some cases considerable, especially when combined at the same time with heat. But those aeriform substances which are more elastic than common air display the most steady and powerful tendency to rise in the atmosphere. Such, in a remarkable degree, is the hydrogen gas, owing pro¬ bably to the expansive force communicated by the very L tness large share of heat which is embodied with it. The late 1 rlll'°' most ingenious and accurate Mr Cavendish, in 1766, as found, by a nice observation, this fluid to be at least seven bv ndish.times lighter than atmospheric air. It therefore occurred to Dr Black of Edinburgh, that a very thin bag filled with hydrogen gas would rise to the cieling of a room. He provided, accordingly, the allantois of a calf, with the Aeronau- view of showing, at a public lecture, such a curious ex- tics- periment before his numerous auditors; but, owing some unforeseen accident or imperfection, it chanced to fail, and that celebrated professor, whose infirm state of health and cold or indolent temper more than once al¬ lowed the finest discoveries, when almost within reach, to escape his penetration, did not attempt to repeat the exhi¬ bition, or seek to pursue the project any farther. Several years afterwards, a similar idea occurred to Mr Cavallo, who found, however, that bladders, though carefully scraped, are too heavy, and that China paper is permeable to the gas. It is rather singular that he did not think of gold-beater’s skin, which had for like purposes been re¬ commended two centuries before by the grammarian Joseph Scaliger and some other writers. But in 1782 this ingenious person succeeded with the pretty experi¬ ment of elevating soap-bubbles, by inflating them with hydrogen gas. To construct an aeronautic machine, it is only required, Power of therefore, to provide a thin bag, of sufficient capacity, andascension- to fill it with hydrogen gas, or with air which is kept in a rarefied state. The form and strength of the material are not so essential as in Lana’s project, since it here suffers an equal pressure on both its outer and its inner side. Nor is it an absolute condition that the substance of the bag should be quite impervious to the gas or confined air; though such a defect, by allowing the partial escape of the buoyant fluid, must inevitably diminish the vigour and abridge the duration of the power of the balloon’s ascent. This power is evidently the excess of the weight of an equal bulk of atmospheric air above the aggregate weight of the included gas, joined to that of the bag, and of all its appendages: in other words, the final power of ascent is the difference between the weight of the included gas and of that of an equal volume of external air, further diminished by the weight of the whole apparatus. But supposing the form of the balloon to remain the same, this counteracting load, as it depends on the quantity of sur¬ face contained in the bag, must be proportioned to the square the diameter; whereas the difference between the internal and external volume of fluid, which consti¬ tutes the whole of the buoyant force, increases in a faster ratio, being proportioned to the capacity of the bag, or the cube of its diameter. It hence follows, that however small the excess may be of the specific gravity of the external air above that of the collected fluid, there must always exist some corresponding dimension which would enable a balloon to mount in the atmosphere. The theory of aeronautics, considered in its detail, in¬ cludes three distinct things : first, the power of a bal¬ loon to rise through the air; second, the velocity of its ascent; and, third, the stability of its suspension at any given height in the atmosphere. These points we shall examine separately. I. The buoyant force of balloons. Since balloons in Buoyancy their shape generally approach to the spherical form, it01 t)dUoons will be more convenient to ground our calculations on that figure. A globe of common air at the level of the sea, and of the mean density and temperature, is found to weigh about the 25th part of a pound avoirdupois. Con¬ sequently, if a perfect vacuum could be procured, a bal¬ loon of ten feet diameter must rise with a force of 40 pounds; one of twenty feet diameter, with that of 320 pounds; and a balloon of thirty feet in diameter would mount in the atmosphere with the power of 1080 pounds: thus augmenting always in the ratio of the cube of the diameters. But air expands by heat about the 450th part from heat; 182 Aeronau tics. AERONAUTICS. from hu¬ midity ; from heat joined to moisture. Smoke bal loons. l“ ifs bulk for each degree on Fahrenheit’s scale. Sup¬ posing, therefore, that the air included within the bag were heated 50 degrees, which is as much perhaps as could be well supported, it would follow *thaf one ninth part of this fluid would be driven out by the warmth, and consequently, that the tendency of the balloon to rise up¬ wards would be equal only to the ninth part of the entire power of ascension. Were it possible to maintain a heat of 75 degrees within the balloon, the buoyant force would yet not exceed the sixth part of the absolute ascensional power. 1 he dilatation which the presence of humidity commu¬ nicates to air will, during fine weather in this climate, amount generally to one eighteenth part, though it may sometimes reach to more than the double of this quantity. But, in the tropical regions, such dilatation will commonly exceed the twentieth part of the volume of fluid. Hence moist air thrown into a bag, likewise wetted, and suf¬ ficiently large, would cause it to rise in the atmosphere. To succeed, however, in this way, the balloon construct¬ ed of coarse linen would require enormous dimensions; not less than three hundred feet in diameter. But it is the union of heat and moisture that gives to air the greatest expansion. The white smoke with which the balloons are filled on Montgolfier’s plan, was found, by computation, to be at least one-third specifically lighter than the external air. This purer sort of smoke is scarcely any thing but air itself charged with vapour, being pro¬ duced by the burning of chopped straw or vine twigs in a brasier, under the orifice of the bag. It would have re¬ quired no fewer than 150 degrees of heat alone to cause the same extent of rarefaction. We have therefore sufficient data for calculating the buoyant force of the common fire, or rather smoke balloons. This force, being estimated about ISJ- pounds avoirdupois when the diameter of the bag is ten feet, would amount to 1562J pounds if the diameter were fifty feet, and to 12,500 pounds if it were a hundred feet. The weight of the linen case may be reckoned at two-fifths of a pound for a sphere of one foot in diameter. Consequently, a balloon of ten feet diameter would, without its appen¬ dages, weigh 40 pounds ; one of fifty feet diameter, 1000 pounds ; and one of a hundred feet diameter, 4000 pounds. Such a balloon of ten feet diameter would need 274 pounds to make it rise, but one of fifty feet diameter would ascend with a force of 562t pounds, and one of a hundred feet diameter would exert an ascending power of not less than 8500 pounds. There is besides to be de¬ ducted the weight of the cordage, the car, the ballast, and the passengers. It would require, on these estimates, a diameter of 33| feet, to procure merely an equilibrium between the weight of the canvass and the buoyant force of the rarefied air. The hydrogen gas obtained from the action of dilute sulphuric acid upon iron filings is only six times lighter than atmospheric air ; but the gas evolved during the so¬ lution of zinc in that acid is not less than twelve times lighter than the standard fluid. The ordinary way of ex¬ amining the specific gravity of the different gases requires a very delicate operation of weighing with the most ex¬ quisite balance ; a serious difficulty, which long retarded our knowledge of their comparative densities. " In one of the notes to his Treatise on Heat, Professor Leslie has pointed out a very simple method, founded on the princi¬ ples of pneumatics, for discovering the relative specific gravities of the aeriform fluids. This consists in observ¬ ing the time that a given portion of the gas, under a de¬ terminate pressure, takes to escape through a very small aperture. The density of the gaseous fluid must be in- c versely as the square of the interval elapsed. Thus, the k hydrogen gas procured from zinc, but without any depu- p, ration, was found, under a pressure of the same column of'"' "V water, to flow thrice as fast as atmospheric air. This ex¬ periment is very striking, and requires no more apparatus than a cylindrical glass jar, open below, and surmounted by a cap terminating in a fine tubular orifice. On a very moderate supposition, therefore, and after B t, making every allowance for imperfect operation, we maywi f consider the hydrogen gas which fills a balloon as six^r' times lighter than the like bulk of common air. Conse¬ quently, such a balloon must exert five-sixths of the whole buoyant force corresponding to its capacity, or will have a tendency to mount in the atmosphere, that is equal to the thirtieth part of a pound avoirdupois for a globe of one foot diameter. A spherical balloon of fifteen feet diameter would hence have a buoyancy of 112^ pounds; one of thirty feet, 900 pounds ; and one of sixty feet no less than 7200 pounds. But thin silk, varnished with caoutchouc or elastic gum, to render it impervious to air, is found to weigh only the twentieth part of a pound when formed into a globe of one foot diameter. A silk balloon of fifteen feet diameter would hence weigh 11} pounds ; one of thirty feet, 45 pounds ; and one of sixty feet diameter, 180 pounds. Wherefore, the power of as¬ cension exerted by such balloons would, in pounds avoir¬ dupois, be respectively 101^, 855, and 7020. It follows, also, that a balloon of a foot and a half in diameter would barely float in the atmosphere, the weight of its varnished silk being then exactly balanced by the buoyant effort of the body of hydrogen gas. But the calculations now given would in strictness re¬ quire a small modification. The weight of the bag and of all the appendages must evidently compress the in¬ cluded gas, and thereby render it in some degree denser. To compute this minute effect, we have only to consider, that the pressure of a column of atmosphere, at the mean temperature, and near the level of the sea, is 1632 pounds, on a circle of a foot diameter. Thus, in the large balloon of sixty feet diameter, if we suppose the whole load to have been 6000 pounds, the compression of the bag would only amount to five-thirds of a pound for each circle of a foot diameter in the horizontal section, or correspond to the 979th part of the entire pressure of the atmosphere. But the weight of the confined gas being 1200 pounds, its buoyancy must have suffered a diminution of somewhat more than a pound, or -A- from the encumbrance opposed to it. This correction is therefore a mere theoretical nicety, which may be totally disregarded in practice. II. The next circumstance to be considered in aero-Cek ^ nautics is, the celerity with which balloons make their ascent. ^1 ! It is obvious that the efficient power of ascension, or the0 2 excess of the whole buoyant force above the absolute weight of the apparatus, would, by acting constantly, pro¬ duce always an accelerated motion. But this acceleration is very soon checked, and a uniform progress maintained, by the increasing resistance which the huge mass must experience in its passage through the air. The velocity which a balloon would gain from unobstructed acceleration must, from the theory of dynamics, be to that which a falling body acquires in the same time, as the efficient buoyancy is to the aggregate weight of the apparatus and of the contained fluid. Thus, if the balloon were to rise with a force equal to the eighth part of its compound weight, the celerity resulting from a constant acceleration w^oulcl be expressed by multiplying four feet into the number of seconds elapsed since it was launched into the air. Its accelerating advance, however, being opposed, AERONAUTICS. 1S3 Ai>inau. la. Terminal velttty* ixriple. rerial brqla. the balloon may to all appearance attain, though still af¬ fected with partial oscillations, the final velocity in per- s haps little more than double the time required without such obstruction. , . . t This final velocity, or the velocity at which the ascent becomes uniform, the resistance from the air being then equal to the efficient buoyancy of the balloon, is easily cal¬ culated. The resistance a circle encounters in moving through any fluid in the direction perpendicular to its plane, is measured by the weight of a column of that fluid, having the circle for its base, and an altitude equal to the height from which a heavy body in falling would acquire the given celerity. But near the level of the sea, and at the mean temperature, a column of atmospheric air 17 feet high, and incumbent on a circle of one foot diameter, weighs a pound avoirdupois ; which is therefore the resist¬ ance that such a circle would suffer if carried forwards with the celerity of 33 feet each second. According to the same theory, however, which we owe to the sagacity of Newton, the resistance of a sphere is just the half of that of its generating circle, and consequently a velocity of 46§ feet in a second through the air would, in ordinary cases, create a resistance of one pound to a ball of one foot diameter. In other circumstances, the quantity of resist¬ ance must be proportional to the squares of the velocities and of the diameters. Whence, if the buoyant force were always the same, the velocity of the ascent of a bal¬ loon would be inversely as its diameter. Suppose a balloon to have thirty feet in diameter, and an ascensional power of 100 pounds. This effort is evi¬ dently the same as the ninth part of a pound for a globe of a foot diameter, and would therefore be countervailed by the resistance corresponding to a velocity of 46S divid¬ ed by 3, the square root of 9, or 15| feet each second. The balloon would therefore reach the altitude of a mile in about six minutes. Its accelerating force being only the sixteenth part of its total weight, it might have acquired the uniform motion of ascent in twenty seconds, or before it had attained the height of 200 feet. This example dif¬ fers very little from reality, and the method of computa¬ tion will easily be transferred to other cases. But the resistance of the air assigned by theory is, from the circumstances omitted in the simplification of the pro¬ blem, generally somewhat less than the results of obser¬ vation. In low velocities this difference amounts seldom to the fifth part of the whole effect; but in the high velocities it increases considerably, exceeding even the third part in certain extreme cases. From the numerous and accurate experiments of Dr Charles Hutton, we may, however, deduce a simple formula for expressing the ter¬ minal velocity of balloons, or the celerity of their uniform ascent. Let a denote the diameter of the balloon in Eng¬ lish feet, and/ its ascensional power, measured in pounds avoirdupois; then—-v// will very nearly represent in feet a " the velocity each second of its regular ascent, or that ve¬ locity which would cause a resistance from the air pre¬ cisely equal to the buoyant force. Or, to express the rule in words: As the diameter of the balloon in feet is to the constant number 40, so is the square root of the ascen¬ sional power in pounds to the terminal or uniform velocity ot ascent each second. To illustrate the application of the formula by an easy example ; suppose the balloon to have a diameter of 60 feet, with an acceleratin'g power of 144 pounds; the corresponding rate of uniform ascent 40 2 becomes —^144, or ^ X 12, that is, 8 feet each second, or about a mile in eleven minutes. III. The last point which demands attention in aero- Aeronau- nautics is, the stability of the suspension of a balloon at any tics‘ given height in the atmosphere. The circumstances which might regulate or determine that stability, requiring some 0faSURpen_ little exercise of thought, have been commonly neglected, sion. and very seldom examined with due care. It will be pro¬ per to consider,/^, the fire or smoke balloons, and, second¬ ly, the balloons filled with hydrogen gas. 1. The warm humified air of the balloon constructed Smoke after Montgolfier’s plan suffering less external compres-^1100113, sion as it approaches the upper strata of the atmosphere, must at the same time necessarily expand, and partly escape by the orifice above the brasier. The weight of the included fluid, and that of the part expelled, constituting its buoyant force, will hence be reduced, in proportion to the diminished density of the medium in which it floats. The balloon will continue to ascend till, its enfeebled buoy¬ ancy is no longer able to support the incumbent load. At the height of a mile above the surface, the power of ascen¬ sion would be diminished rather more than one fifth part; but at an altitude of three miles and a half it would be reduced to one-half. At the ordinary temperature, this buoyancy would suffer a reduction of the hundredth part for each ascent of 278 feet. Resuming the data formerly stated, and supposing the balloon to have a spherical shape, its actual power of ascension, estimated in pounds avoir- d5 dupois, will be denoted by —> where a signifies the dia¬ meter in feet, or the cube of the diameter divided by the constant number 80. If m : n express the ratio of atmo¬ spheric density at the surface and at any given height, then will — denote the diminished buoyant force at m 80 that altitude. We shall select, for example, a balloon of 100 feet dia¬ meter, which is one of the largest dimensions ever ac¬ tually constructed. Near the level of the sea, and at the ordinary temperature, its power of ascension would be 12,500 pounds ; but at the height of8000 feet, or somewhat more than a mile and a half, when the density is diminished one-fourth, or — z=-, that power becomes reduced to m 4 ^><12,500, or 9375 pounds, being a deficiency of 3125 4 pounds. On the supposition that the balloon was at first so much loaded as to rest just suspended at the ground, a bal¬ last of 3125.pounds must have been thrown out, to make it rise to the altitude of a mile and a half. Hence also the rejection of 125 pounds would have been sufficient to give the balloon an elevation of 278 feet. For the same reason, 10 pounds of ballast heaved out would raise it 22 feet at the surface, 29 feet at the height of a mile and a half, and 44 feet at that of three miles and a half. 2. The stability of the suspension of balloons filled with Balloons hydrogen gas must depend on principles which are very charged different and less marked. In these aeronautic machinesAvith hy. after the gas has been once introduced, it is closely shutd™gen up; and therefore, having constantly the same absolute weight, it should likewise, in all situations, exert the same buoyant force. Flence, if the balloon were capable of inde¬ finite extension, it would still continue its ascent through unbounded space. The determinate capacity of the bag alone can oppose limits to its rise in the atmosphere. The upper strata being rarer than those below, will have less power to keep any given bulk suspended ; and the actual buoyancy being diminished from that cause, the balloon will find its station at a corresponding height in the dif¬ fuse medium. But this diminution of the buoyant force, 184 AERONAUTICS. should not he com¬ pletely filled; unstable when flac¬ cid. IMode of adjusting balloons. and the consequent increase in the density of the hydro- gen gas, must necessarily be confined within very mode¬ rate limits, otherwise the thin silk case would be torn to shreds by the expansive efforts of the imprisoned fluid. A safety-valve is accordingly placed at the top of the balloon, calculated to give vent to the gas before the distension has become such as to endanger the bursting of the case. A balloon should not at first be filled completely with hydrogen gas, but allowed to begin its ascent in a flac¬ cid state. As it mounts into the rarer atmosphere, it will gradually swell, till it has attained its full distension, when the safety valve may come to act. But such dissipa¬ tion of the gas ought, by a previous arrangement, to be as much as possible avoided. If the balloon were intended to rise to the height of four miles, it would not be requisite to fill more than half its capacity with the elastic fluid. To push the charge any farther in this case, would only oc¬ casion a superfluous waste of materials. By throwing out part of his ballast, the aeronaut may raise himself higher; and by opening the valve to permit some of the imprison¬ ed gas to escape, he may descend again: but both those expedients are attended by a wasteful expenditure of power. It is evident that a balloon can have no stability of equi¬ poise, so long as it remains in a loose or flaccid state. The slightest action would then be sufficient to make it rise or fall, since, under such circumstances, any change of its station could not in the smallest degree affect the measure of its buoyant force. The general elevation to which the balloon will ascend must be determined by its quantity of ballast, conjoined with the regulation of the safety-valve; but the strain of the silk case itself would be sufficient to confine the ascent within certain limits, and to procure the stability of the floating mass. Thus, if a balloon fully distended had yet a slight disposition to rise, the imprisoned gas, suffering more and more compression as it gradually ascends, would become proportionally den¬ ser, and therefore lose a corresponding part of its previous buoyancy. An equilibrium would hence soon obtain, which must arrest the floating machine at a determinate height in the atmosphere. Suppose a balloon to be capable, without any danger of bursting, of sustaining an expansion equal to the hun¬ dredth part of the elasticity of the included fluid; the whole buoyancy would, by such an alteration, be diminished one five hundredth part,' or this floating machine would sub¬ side 55 feet near the surface, and sink proportionally more in the upper regions. To produce the effect, it would only be requisite to throw common air into the bag, with¬ out suffering any portion of the hydrogen gas to escape. On this principle Meusnier, an ingenious French chemist, very soon after the first discovery of balloons, proposed to regulate with nicety their ascent and position of equili¬ brium in the atmosphere. The mode which he suggested was, to place within the principal balloon a much smaller one, to be filled occasionally with common air by help of bellows, or emptied again by opening an exterior valve. The aeronaut would thus have it in his power, without expending the charge of hydrogen gas, either to sink gently through a short space, or to rise again at will, by inflating the inner balloon, or allowing it to collapse. The adjustment of the height of a balloon could hence be man¬ aged with great precision. The command possessed by the aeronaut of raising or depressing his machine at pleasure, might afford him the means of influencing the direction of its course. From the various motions of the several ranges of clouds, we may infer that different currents exist at the same time in the atmosphere. The aeronaut has, therefore, in his as¬ cent, only to seek the current best suited to his purpose Ao, and, taking his station in that stratum, to commit his ffioi! ^ sy vessel to the guidance of the stream. ^ Any other attempts to direct or control the flight of ^ balloon are altogether fallacious. Since it is carried alongapip with the swiftness of the wind, no rudders or sails cans% have any action whatever. The aeronaut might fancy1111 himself to float in a perfect calm, unless he chances to en¬ counter irregular currents. The application of oars may turn a balloon, but can have no sensible effect in divertino- or impelling its course. How vastly disproportionate is the force of the human arm to the overwhelming pressure of the wind against so huge a machine! To adapt ma¬ chinery under these circumstances would be preposterous and to look for help from such a quarter is visionary in the extreme. It must be admitted, however, that after a bal¬ loon has once gained its station of equilibrium, or passively floats in the air, the vigorous action of broad vanes, down¬ wards or upwards, might serve to raise or depress the machine through a small space. Thus, a vertical force, exerted equal to nine pounds, would lift a balloon of thirty feet in diameter 278 feet higher. The application of bal¬ last is hence infinitely preferable to any such bulky and unmanageable apparatus. At the period where we left our narrative, the principles on which a balloon could be constructed were therefore pretty generally known to men of science. But to reduce these principles to complete effect, was still an enterprise of the most dazzling kind. This experiment seemed un¬ fit for a cabinet or a laboratory, and it could succeed only on a large scale, exposed to the gaze of the multitude. W ithout the toil of investigation, or indeed any exercise of thought, all the world might witness the result, and admire the magnificent spectacle which it would present. This triumph over matter was at length achieved by the^i, skill and perseverance of Stephen and Joseph Montgolfier, Md, sons of the proprietor of an extensive and very celebrated fier i- paper manufactory established at Annonay, on the banksual - of a rivulet which flows into the Rhone, near forty miles c0!, e below Lyons. These remarkable persons, though bred inba ' a remote provincial town, possessed in a high degree in¬ genuity and the spirit of observation. Without' having the benefit of a liberal education, their active curiosity had led them to acquire a more extensive and accurate stock of knowledge than is usually found in the same | condition of life. Stephen was more attached to mathe- ! matics, but Joseph directed his studies chiefly to chemistry ; and natural philosophy. They were associated in business with their father, who passed his quiet days, like a patri¬ arch, amidst a large family, and a numerous body of work¬ men, and reached the very advanced age of 93. Of the younger brother, who survived the other, and lived to make the very valuable yet much neglected discovery of the hydraulic ram, we may venture to speak from personal acquaintance. He was a man of great modesty and sim¬ plicity of character, yet firm and undaunted, of a calm and sedate aspect, tall and athletic in his person, and of a swarthy complexion, not unlike the celebrated Mr Watt, whom he resembled in some other particulars of his for¬ tune. He was too speculative, perhaps, to succeed in the details of business; for, after trying various schemes of im¬ provement, he quitted his paper manufactory and repaired to the capital, where he obtained a situation of trust un¬ der the late imperial government, at the -chamber of mo¬ dels, as inspector of patents and internal improvements. In 1809 he had a stroke of palsy, which induced him to i esort to the waters of Bourbonne; but receiving no be¬ nefit from them, he gladly preferred those of Balaruc, AERONAUTICS. 185 A-r. iu- near his old friends, where he died on the 26th of June in * ti the following year, at the age of 60. The two brothers, who were accustomed to form their 'hajsuc-p]ans in concert, had long contemplated the floating and !X" ascent of clouds in the atmosphere. It seemed to them, enn n S that a sort of factitious cloud, formed of very thin vapour, inclosed in a light bag of immense size, would mount to the higher regions. In pursuit of this idea, they selected a fluid specifically lighter than atmospheric air ; and, ac¬ cordingly, introduced hydrogen gas into large bags of paper and of thin silk, which rose up, as had been expect¬ ed, to the cieling, but fell down in a few seconds, owing to the rapid escape of the gas through the cracks and pores of the case. This great facility with which hydro¬ gen gas makes its way through any substance of a loose and incompact texture, is partly due to its extreme flui¬ dity, but is chiefly occasioned by its strong and obstinate attraction for common air. The mode of preventing, or at least checking that escape, by the application of a proper varnish, was yet unknown. The prospect of overcoming the Idifliculty was so discouraging, that our experimenters had recourse to another scheme, more analogous to their origi¬ nal ideas, and it rewarded their continued efforts with the most complete success. In the month of November 1782, Joseph Montgolfier, happening, in the course of his fre- quent excursions, to be then at Avignon, procured a small silk bag, of the form of a parallelopipedon, open below, like ia lady’s hoop, and having a capacity of about forty-five cubic feet; under its orifice he burnt some paper, and saw, with inexpressible transport, the bag quickly swell, and mount rapidly to the height of seventy-five feet, where it * remained till by cooling it lost its buoyancy. Returning to Annonay, he communicated the happy result to his brother, and it was resolved by them to prosecute the ex¬ periment on a large scale. Having provided a large quan¬ tity of coarse linen, they formed it into the shape of a globe, about thirty feet in diameter, which they lined with paper. On lighting a fire within its cavity, to warm and expand the air, they had the delightful satisfaction of seeing the bag ascend with a force equivalent to 500 pounds. It was very natural that the brothers should now de¬ sire an occasion for exhibiting this grand experiment in their native town. They invited the members of the pro¬ vincial meeting of the states of the Vivarais, then assem¬ bled at Annonay, to witness the first public aerial ascent, nrstjib. On the 5th June 1783, amidst a very large concourse of spectators, the spherical bag or balloon, consisting of difi. oon. " . rent pieces of linen, merely buttoned together, was sus¬ pended from cross poles ; two men kindled a fire under it, and kept feeding the flames with small bundles of chopped straw ; the loose bag gradually swelled, assuming a grace¬ ful form, and in the space of five minutes it was com- | pletely distended, and made such an effort to escape, that eight men were required to hold it down. On a signal being given, the stays were slipped, and the balloon in¬ stantly rose with an accelerating motion, till it reached some height, when its velocity continued uniform, and carried it to an elevation of more than a mile. All was admiration and transport. Amidst the shouts of unbound¬ ed acclamation, the progress of the artificial cloud retiring rom sight arrested every eye. It was hurried along by t ie wind; but, its buoyant force being soon spent, it re¬ gained suspended only ten minutes, and fell gently in a vineyard, at the distance of about a mile and a half from the P ace of its ascension. So memorable a feat lighted up t le glow of national vanity, and the two Montgolfiers were jailed and exalted by the spontaneous impulse of their teilow-citizens. Of this splendid experiment a very hasty and imperfect account was transmitted to Paris, and quickly circulated Aeronau- over Europe. In those halcyon days, during the transient tics, calm of political turmoils, and the happy absence of all military events, the prospect of navigating the atmosphere The V"' excited a very general ferment, and engrossed the con- madebv it versation of all ranks. Yet the tale appeared so extraordi- in^urope. nary as to leave some doubts of its veracity. In many places, and especially in this country, the more ignorant class of men, and those who affected superior wisdom, both agreed in considering the relation of Montgolfier s discovery as nothing but an imposition practised on the public credulity. To dispel the suspicions which infected the subject, it was necessary to repeat the experiment in every large capital. When the intelligence of the first ascent of a balloon reached St Petersburg, it found the venerable Euler in a state of great debility, worn out with years and unremit¬ ting intellectual toil. Having lost, in the middle of his career, the sight of an eye, he had been for several years visited with total blindness. But in this afflicting situa¬ tion his mind was still entire, and found delightful exer¬ cise in his former habits of calculation. It was in training a domestic to act as his amanuensis, that this great genius now condescended to dictate, in the German language, to his humble pupil, a work of the highest merit, The Ele¬ ments of Algebra. During his last illness, Euler made an expiring effort, and applied his favourite analysis to de¬ termine the ascending motion of a balloon. He dictated the preliminary steps of the problem to one of his grand¬ children : but the hand of death was already stretched over the patriarch ;—no farther could he proceed with his investigation ;—and composing himself for nobler scenes, he calmly expected the moment of dissolution. The virtuosi at Paris were eager to repeat the experi- imitated ment of the ascension of a balloon. M. Faujas de St Fond, at Paris, an active and zealous naturalist, set on foot a subscription for defraying the expense, which was soon filled up. The construction of the machine was intrusted to the skill of two brothers of the name of Robert, under the superin¬ tendence of M. Charles, an ingenious lecturer in natural philosophy. It had at first been proposed merely to copy the process of Montgolfier, but Chaides preferred the ap¬ plication of hydrogen gas; a resolution which afterwards occasioned much difficulty and delay. The balloon con¬ sisted of thin silk or tiffany, varnished with a solution of elastic gum, disposed into a globular shape, of about thirteen feet in diameter. The hydrogen gas was procured from the action of dilute sulphuric acid upon iron-filings, and was introduced through leaden pipes. But this gas, being rapidly formed, without having been made to pass through a body of cold water, entered the cavity of the balloon excessively hot, and charged with acid fumes, which after¬ wards condensed against the inside of the bag, injuring its texture, and loading it with superfluous humidity. Not fewer than 500 pounds of sulphuric acid were used, and twice this weight of iron-filings; yet several days were spent in abortive attempts to fill the balloon completely. At last it rose, and was kept suspended at the height of 100 feet above the ground. In this state it was convey¬ ed with acclamations to the Place des Victoires, where it rested, and underwent some repair. About midnight it was thence transported in silent procession, preceded by torch-lights, and guarded by a detachment of horse and foot soldiers, to the Champ de Mars, at the distance of near two miles. The few passengers found at that still hour on the streets gazed with astonishment at the float¬ ing mass; and the very coachmen, filled with a sort of awe, respectfully saluted it as they passed. Next day, being the 27th of August 1783, an immense 2 A 186 AERONAUTICS.

By Charles 0t ^iree 0’e^0Ch every avenue was filled with carriages, and ami Ro- t^ie beauty and fashion of Paris flocked towards the bert. Ecole Militaire. The preparations being finished, a can¬ non was discharged as the signal of ascent. The balloon, liberated from its stays, shot upwards with such rapidity as in two minutes to reach, according to calculation, the height of 3000 feet, wher* it seemed lost in a dark cloud. It re-appeared at a greater elevation, but was soon obscured again amidst other clouds; and after performing a flight of about fifteen miles in the space of three quarters of an hour, it sunk to the ground in a field near Ecouen, where the peasants secured it, having noticed a rent in the upper part of the bag, to which its fall might be im¬ puted. The success of the experiment was complete. The incredulous were sadly mortified; but every minor reflection was drowned in the tumult of excessive joy and exultation. It began to rain immediately after the balloon was launched, yet this unlucky circumstance had no effect to abate the curiosity of the spectators. Regardless of the torrents that fell, they were wholly absorbed in following with eager gaze the progress of the machine through the air. Even elegant ladies, dressed in their finest attire, stood exposed, looking intently the whole time, and were drenched to the skin. This small balloon weighed only thirty pounds, and had at first a buoyant force of forty pounds avoirdupois. If we employ the formula before given, the terminal velocity would be — yMO — 19 f~ feet in a second, or 1168 feet each minute; which appears to correspond very well with fact. Joseph About this time Joseph Montgolfier visited Paris, and Montgol- was invited by the Royal Academy of Sciences to repeat tier eon- experiment of Annonay on a larger scale. He con- e structed, with coarse linen and a paper lining, a balloon loons at a Pear shape, and about 43 feet wide and 75 feet high. Paris. The smoke of fifty pounds of dry straw, in small bundles, joined to that of twelve pounds of wool, was found suf¬ ficient to fill it in the space of ten minutes. The bag duly swelled, and made an effort to rise equivalent to the weight of 500 pounds ; but being reserved for exhibition the next day, it was totally destroyed, by its exposure during the night to incessant and violent rain. It became necessary, therefore, to prepare another balloon; and such was the expedition of the artist, that in five days he go't the whole completed. Early on the morning of the 19th of September, it was placed upon an octagon scaffold, in front of the palace of Versailles. It had a very showy appearance, being painted with ornaments in oil colours. By ten o’clock the road from Paris was crowded with car¬ riages of all descriptions. Every person of any note or fashion hurried from the metropolis to view the experi¬ ment ; ladies of distinguished rank filled the windows; and the spacious courts and walks, and even the tops of the houses, were covered with impatient spectators. The royal family and their attendants came forth, and examined the details of the apparatus. About one o’clock the dis¬ charge of a mortar gave notice that the filling of the bal¬ loon was to commence. In eleven minutes another dis¬ charge announced that it was completely inflated; and on the third discharge of the mortar, the cords were cut, and the balloon instantly liberated. After balancing at first in a moment of anxious expectation to the spectators, it rose majestically, in an oblique direction, under the impulse of the wind, till it reached the height of 1500 feet, where it appeared for a while suspended; but in the space of eight minutes it dropped to the ground, at the distance of two miles from the point of its ascent. A sheep, a cock, and Aei a duck, which had been put into the basket, the first ani- 1 mals ever carried up into the air, were found perfectly^ safe and unhurt by the journey, and the sheep even feed¬ ing at perfect ease. See Plate II. for a view of this bal¬ loon and the following ones. This successful experiment encouraged Montgolfier to prepare, on a more solid construction, another balloon, of a spheroidal form, 45 feet wide and 75 feet high. While it was filling with smoke, Pilatre de Rozier, a young na¬ turalist of great promise, and full of ardour and courage, leaped into the car, and was borne up to the height of 300 feet, where he continued some minutes suspended, the balloon being held down by long cords till it gently de¬ scended. The dangers of navigating the balloon being thus brought to a more correct estimate, it was resolved speedily to attempt the daring but sublime experiment. The badness of the weather, however, at this late season of the year, made the project be deferred several days. At last, on the 21st of November, every thing was ready for the ascent in the spacious gardens of the chateau of Muette, belonging to the court of the Dauphin. The sky had a lowering aspect, being loaded with heavy clouds, driven about by irregular winds. But the adventurers were not to be easily discouraged. After a first trial, Ma which had nearly proved fatal to them, the balloon wasfirs again filled; and Rozier, with the marquis d’Arlandes, av0.v major of infantry, who had volunteered to accompany him, took their seats in the car, having a store of ballast, and a provision of straw to supply the fire. About two o’clock the machine was launched, and it mounted with a steady and majestic pace. Wonder, mingled with anxiety, was depicted in every countenance ; but when, from their lofty station in the sky, the navigators calmly waved their hats, and saluted the spectators below, a general shout of accla¬ mation burst forth on all sides. As they rose much higher, however, they were no longer discernible by the naked eye. ni. o t’a ill in the surging smoke Uplifted spurn the ground; thence many a league, As in a cloudy chair ascending, ride Audacious. This balloon soared to an elevation of more than 3000 feet, and traversed, by a circuitous and irregular course, the whole extent of Paris, whose gay inhabitants were all absorbed in admiration and amazement. A curious cir- J ; cumstance occurred during the passage of the floating | I mass : to the gazers planted on the towers of the metro¬ politan church of Notre Dame, it chanced to intercept the body of the sun, and thus gave them, for a few seconds, the spectacle of a total eclipse. It has been alleged, that when the balloon had reached so high that the objects on earth were no longer distinguishable, the marquis d’Ar¬ landes began to think that his curiosity and ambition were sufficiently gratified. He was therefore anxious to descend, and murmured against his companion, who still kept feeding the fire. At last, on hearing some cracks from the top of the balloon, and observing holes burning in the sides, the major became outrageously alarmed at his imminent danger, and applying wet sponges to stop the progress of combustion, he compelled the savant to desist > from his officious operations. As they now descended too fast, however, M. d’Arlandes' was not less anxious and diligent in throwing fresh straw upon the fire, in order to gain such an elevation as would clear the different ob¬ stacles. The navigators dexterously avoided the lofty buildings of Paris, by supplying fuel as occasion required; and, after a journey of 20 or 25 minutes, they safely alighted beyond the Boulevards, having described a track of six miles.

It will therefore be sufficient henceforth to notice very succinctly some of the more dis¬ tinguished attempts of that kind. Andreani. The Chevalier Paul Andreani of Milan had a spherical balloon, of 70 feet in diameter, formed after Montgolfier’s plan, at his own charge, in which, accompanied by two companions, he ascended from that capital on the 25th of February 1784. The machine rose to the height of 1300 feet; but after having described, in twenty minutes, a very circuitous track, it settled upon a large tree, from which however the voyagers, by applying fresh fuel, ex¬ tricated themselves, and alighted on clear ground, without receiving any hurt. Blanchard. On the 2d of March Blanchard, who had been for some years before occupied with the chimerical project of flying in the air, and who fancied that the same prin¬ ciples and contrivances might be applied to direct the mo¬ tion of balloons, mounted alone, and with great intrepidity, at Paris, in a silk balloon 40 feet in diameter, constructed by subscription, and filled with hydrogen gas. He darted rapidly to the height of above a mile, and after being driven about by cross winds for an hour and three quarters, he descended in the plain of Billancourt. On the 28th of June in the same year, an ascent was made at Lyons before the King of Sweden, who then tra¬ velled under the name of Count Haga, with a fire-balloon, having somewhat of a pear shape, and 75 feet in height. T-'leurant Two passengers, M. Fleurant and a young lady, Madame andThible. Thible, the first female that ever adventured on such a daring voyage, entered the car, and ascended with great velocity. In four minutes the noise of the multitude was no longer audible, and in two more the eye could not dis¬ tinguish them. It was inferred, from a trigonometrical cal¬ culation, that they had reached the altitude of 13,500 feet. Their flag, with its staff of 14 pounds weight, being thrown down, took seven minutes to fall to the ground. The thermometer had dropt to 43° on Fahrenheit’s scale ; and to the sensation of cold which they felt was joined that of a ringing in the ears. Different currents were found to occupy distinct strata of the atmosphere ; and in passing from one stratum to another, the balloon was affected by a sensible undulation. The travellers continued to feed their fire with the loppings of vines, till this provision being nearly spent, they safely alighted in a corn-field, having traversed about six miles in three quarters of an hour. Rozierand About a fortnight afterwards, the same prince was gra- Proust. tified by a more splendid ascent, commanded for his en¬ tertainment by the French monarch. A large fire-balloon, carrying the naturalists Rozier and Proust, was launched from the outer court of Versailles. It soared to the height of 12,520 feet, and might appear to float in a vast con¬ gregation of extended and towering white clouds. The thermometer stood at 21° of Fahrenheit, and the flakes of snow fell copiously on the voyagers, while it only rained below. ' Descending again from that chaotic abyss, they were charmed with the lively aspect of a rich and populous district. They alighted at the entrance of the forest of Chantilly, about thirty-six miles from Versailles, after a flight of an hour and five minutes. We omit the relation of a prosperous ascent performed at Rhodes on the 6th of August, by the Abbe Carnus 4 and his companion, with a fire-balloon, of a globular shape, 1,1,11 and 57 feet in diameter.—The longest aerial journey yetM made was accomplished at Paris, on the 19th of Septem¬ ber. The duke de Chartres, afterwards Orleans, and the d noted Egalite, employed Robert to construct for him a0 silk balloon, which should be filled with hydrogen gas. It had 56 feet in height and 36 feet diameter, being compos¬ ed of a cylinder terminated by two hemispheres ; a con¬ struction which was rightly supposed to give much ad¬ ditional solidity to the machine. A small bag, on Meus- nier’s plan, had been introduced within it, and the boat besides, furnished with a helm and four oars. This balloon, bearing the duke himself, the two artists, and an¬ other companion, and having 500 pounds of ballast, was allowed to rise very slowly, with a buoyancy of only 27 pounds. At the height of 1400 feet, the voyagers perceiv¬ ed, not without uneasiness, thick dark clouds gathering along the horizon, and threatening the approach of a thun¬ der-storm. They heard the distant claps, and experienced something like the agitation of a whirlwind, although they had not felt the slightest concussion in the air from the dis¬ charge of cannon. The thermometer suddenly dropped from 77° Fahrenheit to 61° ; and the influence of this cold caused the balloon to descend within 200 feet of the tops of the trees near Beauvais. To extricate themselves, theynow threw out more thanforty pounds of ballast, and rose to an elevation of 6000 feet, where it was found that the confined gas had so obstinately retained its heat, as to be no less than 42° warmer than the external air. The duke became alarmed, and betrayed such impatience to return again to the earth, that he is said to have pierced the lower part of the silk bag in holes with his sword. After narrowly escaping the dangers from wind and thunder, the balloon at last descended in safety near Bethune, having perform¬ ed a course of 135 miles in the space of five hours. On the 25th of April in the same year, the celebrated Gt chemist Guyton-Morveau, with the Abbe Bertrand, as-Mli cended from Dijon in a balloon, nearly of a globular shape, 29 feet in diameter, composed of the finest varnish¬ ed tiffany, and filled with hydrogen gas. They did not start till five o clock in the evening, the barometer being at 29*3 inches, and the thermometer at 57° on Fahren¬ heit’s scale ; and, after surmounting some accidents, they rose ,to an altitude of 10,465 feet, or very nearly two Eng¬ lish miles, where the barometer had sunk to 19-8 inches, and the thermometer to 25°. They felt no inconvenience, however, except from the pinching of their ears with cold. They saw an ocean of clouds below them, and in this si¬ tuation they witnessed, as the day declined, the beautiful phenomenon of a parhelion, or mock sun. The real lumi¬ nary was only ten degrees above the horizon, when, all at once, another sun appeared to plant itself within six de¬ grees of the former. It consisted of numerous prismatic rings, delicately tinted, on a ground of dazzling whiteness. At half-past six o’clock, after a voyage of an hour and a half, they safely alighted near Magny, about fifteen miles distant from Dijon. With the same balloon, M. Guyton-Morveau made ajiis second ascent on the 12th of June, accompanied by theascf I resident De \ irly. It was launched at seven o’clock in the morning, the barometer being then at 29*5 inches, the thermometer at 66°, and Saussure’s hygrometer at 81^°. It swelled very fast, however, owing to the effect of the sun s increasing heat; and the upper valve being at inter¬ vals opened, to give vent to excess of the gas, this escaped with a noise like the rushing of water. As the voyagers did not mount to any very great elevation, they enjoyed an agreeable temperature, and could easily, by observing AERONAUTICS. 189 Ah- au- the situation of the different villages scattered below them, tj. trace out their tortuous route on the surface of the map. By nine o’clock they had reached the height of 6030 feet, the barometer now standing at 24*7 inches, the thermome¬ ter at 70°, and the hygrometer at 65£. Three quarters of an hour afterwards they descended at the village of Ete- vaux, only twelve miles from Dijon, having described at least double this distance in the air. The heat had in¬ creased so much since the morning, that, notwithstanding the loss of elastic fluid, the balloon seemed yet nearly in¬ flated on touching the ground. Ren ka- An aerial voyage, most remarkable for its duration and Ljevi'age its adventures, was performed on the 18th of June 1786, jt'T u. from Paris, by M. Testu, with a balloon 29 feet in diameter, constructed by himself, of glazed tiffany, furnished with auxiliary wings, and filled, as usual, with hydrogen gas. It had been much injured by wind and rain during the night before its ascension; but having undergone a slight repair, it was finally launched, with its conductor, at four o’clock in the afternoon. The barometer then stood at 29-68 inches, and the thermometer as high as 84°, though the day was cloudy and threatened rain. The balloon had at first been filled only five-sixths, but it gradually swelled as it became drier and warmer, and acquired its utmost distension at the height of 2800 feet. But, to avoid the waste of gas or the rupture of the silk, the navigator endeavoured to descend by the re-action of his wings. Though this force had little efficacy, yet at half-past five o’clock he softly alighted on a corn-field in the plain of Montmorency. Without leaving the car, he began to collect a few stones for ballast; when he was surrounded by the pro¬ prietor of the field and a troop of peasants, who insisted on being indemnified for the damage occasioned by his idle and curious visitors. Anxious now to disengage himself, he persuaded them that, his wings being broken, he was wholly at their mercy. They seized the stay of the balloon, which floated at some height, and dragged their prisoner through the air in a sort of triumph towards the village. But M. Testu, finding that the loss of his wings, his cloak, and some other articles, had considerably lightened the ma¬ chine, suddenly cut the cord, and took an abrupt leave of the clamorous and mortified peasants. He rose to the re¬ gion of the clouds, where he observed small frozen parti¬ cles floating in the atmosphere. He heard thunder roll¬ ing beneath his feet, and, as the coolness of the evening advanced, the buoyant force diminished, and, at three quarters after six o’clock, he approached the ground near the abbey of lloyaumont. There he threw out some bal¬ last, and in the space of twelve minutes rose to a height of 2400 feet, where the thermometer was only 66 degrees. He now heard the blast of a horn, and descried huntsmen below in full chace. Curious to witness the sport, he pulled the valve, and descended, at eight o’clock, between Etouen and Varville, when, rejecting his oars, he set him¬ self to gather some ballast. While he was thus occupied, the hunters galloped up to him. He mounted a third time, and passed through a dense body of clouds, in which thun¬ der followed lightning in quick succession.

In this region the voyager sailed till >a t-past nine o’clock, at which time he observed from his watch-tower in the sky” the final setting of the sun. ie was now quickly involved in darkness, and enveloped in the thickest mass of thunder-clouds. The lightnings Aeronau- flashed on all sides, and the loud claps were incessant. tics- The thermometer, seen by the help of a phosphoric light which he struck, pointed at 21°, and snow and sleet fell copiously around him. In this most tremendous situation the intrepid adventurer remained the space of three hours, the time during which the storm lasted. The balloon was affected by a sort of undulating motion upwards and down¬ wards, owing, he thought, to the electrical action of the clouds. The lightning appeared excessively vivid, but the thunder was sharp and loud, preceded by a sort of crack¬ ling noise. A calm at last succeeding, he had the plea¬ sure to see the stars, and embraced this opportunity to take some necessary refreshment. At half-past two o’clock the day broke in; but his ballast being nearly gone, and the balloon again dry and much elevated, he resolved to descend to the earth, and ascertain to what point he had been carried. At a quarter before four o’clock, having already seen the sun rise, he safely alighted near the vil¬ lage of Campremi, about 63 miles from Paris. At this period, ascents with balloons had been multi-Balloons in plied, not only through France, but all over Europe. They England, were very seldom, however, directed to any other object than amusement, and had soon degenerated into mere exhibitions for gain. The first balloon seen in England was constructed by an ingenious Italian, the Count Zam-Zambec- beccari. It consisted of oiled silk, in a globular shape, cari. about ten feet in diameter, and weighed only eleven pounds. It was entirely gilt, which riot only gave it a beautiful appearance, but rendered it less permeable to the gas. On the 25th of November 1783 it was filled about three-fourths, and launched at one o’clock from the artillery ground, and in the presence of a vast concourse of spectators. At half-past three in the afternoon it was taken up at Petworth, in Sussex, about the distance of 48 miles. It was not till the following year, on the 21st of September, that a countryman of his, named Lunardi, first mounted I.unardf. in a balloon at London. He afterwards repeated the ex¬ periment in different parts of England, and during the following year in Scotland. This active person took an expeditious but careless method of filling his balloon with gas. He had two large casks, sunk into the ground for their better security, in which he deposited 2000 pounds of the borings of cannon, divided by layers of straw, to present a larger surface. An equal weight of sulphuric acid, or common oil of vitriol, diluted with six times as much water, was poured upon the iron, and the hydrogen gas now formed, without being cooled or washed, was im¬ mediately introduced into the balloon. To Lunardi suc¬ ceeded Blanchard, who possessed just as little science,Blanchard, but had greater pretensions, and some share of dexterit}' and skill. This adventurer is said to have performed not fewer than thirty-six voyages through the air, and to have acquired a large sum of money by those bold and attractive exhibitions. His most remarkable journey was across the British Channel, in company with Dr Jeffries, an Ameri¬ can physician. On the 7th of January 1785, in a clear frosty day, the balloon was launched from the cliff of Dover, and, after a perilous course of two hours and three quarters, it alighted in safety on the edge of the forest of Guiennes, not far beyond Calais. By the magistrates of this town were the two aerial travellers treated with the utmost kindness and hospitality; and their wondrous ar¬ rival was welcomed as a happy omen, alas! how fallaci¬ ous, of the lasting harmony to subsist between rival na¬ tions, now cemented by the conclusion of the famous Commercial Treaty.

Aeronau- have gradually fallen into disrepute, and the more elegant ties. an{j expensive, but far more powerful construction, which employs varnished silk to contain hydrogen gas, came to be generally preferred. With due precaution and management, the sailing through the atmosphere is perhaps scarcely more dangerous now than the navigating of the ocean. Of some hundred ascents made at different times with balloons, not above two or three cases are recorded to have had a fatal termination. The first was rendered memorable by the shocking death of the accomplished and interesting Rozier, who perished a martyr to his ardent zeal for the promotion of science. Being anxious to return the visit which Blanchard and Jeffries had paid to the French coast, by crossing the channel again and descending in England, he transported his balloon, which was of a globular shape, and forty feet in diameter, to Boulogne; and after various delays, oc¬ casioned chiefly by adverse winds, he mounted on the 15th June 1785, with his companion M. Romain. From some vague idea of being better able to regulate the ascent of the balloon, he had most incautiously suspended below it a small smoke one of ten feet diameter; a combination to which may be imputed the disastrous issue. Scarcely a quarter of an hour had elapsed, when the whole apparatus, ltomaPnd at ^le °f above three thousand feet, was observed onmm. to ke on £re. an(j jtg scat;tered fragments, with the unfor¬ tunate voyagers, were precipitated to the ground. They fell near the sea-shore, about four miles from Boulogne, and were instantly killed by the tremendous crash, their bodies being found most dreadfully mangled. The next fatal accident with balloons happened in Italy, several years later, when a Venetian nobleman and his lady, after having performed successfully various ascents, fell from a vast height, and perished on the spot. Shocking late of The Para. Balloonists have no doubt been often exposed, in their clmte. aerial excursions, to the most imminent hazard of their lives. The chief danger consists in the difficulty of pre¬ venting sometimes a rapid and premature descent. To guard, in some degree, against the risks arising from the occurrence of such accidents, the Parachute was after¬ wards introduced ; being intended to enable the voyager, in case of alarm, to desert his balloon in mid-air, and drop, without sustaining injury, to the ground. The French language, though not very copious, has yet supplied this convenient term, signifying a guard for falling, as it has likewise furnished the words of analogous composition, parapluie, paravent, and parasol, to denote an umbrella, a door-screen, and a shade for the sun. The parachute very much resembles the ordinary umbrella, but has a far greater extent. The umbrella itself, requiring such strength to bear it up against a moderate wind, might na¬ turally have suggested the application of the same prin¬ ciple to break the force of a fall. Nothing was required but to present a surface having dimensions sufficient to experience from the air a resistance equal to the weight of descent, in moving through the fluid with a velocity not exceeding that of the shock which a person can sustain without any danger. Accordingly, in the East, where the umbrella, or rather the parasol, has been from the remot¬ est ages in familiar use, this implement appears to be occasionally employed by vaulters, for enabling them to jump safely from great heights. Father Loubere, in his curious account of Siam, relates that a person, famous in that remote country for his dexterity, was accustomed to divert exceedingly the king and the royal court by the prodigious leaps which he took, having two umbrellas with long slender handles fastened to his girdle. Fie general!}7 alighted on the ground, but was sometimes car¬ ried by the wind against trees or houses, and not unfre- i«i quently into the river. Not many years since, the um- i brella was, at least on one occasion, employed in Europe with similar views, but directed to a very different purpose.^) A In the early part of the campaign of 1793, the French general Bournonville, having been sent by the National Convention, with four more commissioners, to treat with the Prince of Saxe-Cobourg, was, contrary to the faith or courtesy heretofore preserved in the fiercest wars that have raged among civilized nations, detained a prisoner with his companions, and sent to the fortress of Olmutz, where he suffered a rigorous confinement. In this cruel situation he made a desperate attempt to regain his liber¬ ty. Flaving provided himself with an umbrella, he jump, ed from a window at the height of forty feet; but being a very large heavy man, this screen proved insufficient to check his precipitate descent. He struck against the oppo¬ site wall, fell into the ditch, and broke his leg, and was carried in this condition back again to his dungeon. Blanchard was the first who constructed parachutes, Fi and annexed them to balloons, for the object of effecting his escape in case of accident. During the excursion which he undertook from Lisle, about the end of August 1785, when this adventurous aeronaut traversed, without halting, a distance not less than 300 miles, he let down a dog from a vast height in the basket of a parachute, and the poor animal, falling gently through the air, reached the ground unhurt. Since that period the practice and management of the parachute have been carried much farther by other aerial travellers, and particularly by M. Garnerin, who has dared repeatedly to descend from the region of the clouds with that very slender machinev This ingenious and spirited Frenchman visited London Girii'i during the short peace of 1802, and made two fine ascentsdef; with his balloon, in the second of which he threw himself from an amazing elevation with a parachute. This con¬ sisted of thirty-two gores of white canvass formed into a hemispherical case of twenty-three feet diameter, at the top of which was a truck or round piece of wood ten inches broad, and having a hole in its centre, admitting short pieces of tape to fasten it to the several gores of the can¬ vass. About four feet and a half below the top, a wooden hoop of eight feet in diameter was attached by a string from each seam ; so that when the balloon rose, the pa¬ rachute hung like a curtain from this hoop. Below it was suspended a cylindrical basket covered with canvass, about four feet high, and two and a quarter wide. In this basket the aeronaut, dressed in a close jacket and a pair of trousers, placed himself, and rose majestically from an inclosure near North Audley Street at six o’clock in the evening of the 2d of September. After hovering seven or eight minutes in the upper region of the atmosphere, he meditated a descent in his parachute. Well might he be supposed to linger there in dread suspense, and to look a while Pondering his voyage; for no narrow frith He had to cross He views the breadth, and, without longer pause, Downright into the world’s first region throws His flight precipitant, and winds with ease, Through the pure marble air, his oblique way. He cut the cord by which his parachute was attached to the net of the balloon; it instantly expanded, and for some seconds it descended with an accelerating velocity till it became tossed extremely, and took such wide oscil- j lations that the basket or car was at times thrown almost into a horizontal position. Borne along likewise by the influence of the wind, the parachute passed over Mary-le- bone and Somers-town, and almost grazed the houses of St Pancras. At last it fortunately struck the ground in a W-neighbouring field; but so violent was the shock as to % thr„w poor Garnerm on his face, by winch accident he rv'^rec AERONAUTICS. 191 Hutton's valuable experiments for the basis of the calcula- Aeronau- tion, the terminal velocity of descent may be expressed in ived s«m£^lutf:;^rKi/;/eiTKu!r!er^ round numbers, by ^ in feet each second, and con- lUtf. to be much agitated, and trembled exceedingly at the moment he was released from the car. One of the stays of the parachute had chanced to give way; which un¬ toward circumstance deranged the apparatus, disturbed its proper balance, and threatened the adventurer, during the1 whole of his descent, with immediate destruction. The feeling of such extreme peril was too much for human nature to bear. i f prom the principles before explained, we may easily e j'a determine the descent of a parachute. When, with its attached load, it is abandoned in the air, it must, from the continued action of gravity, proceed at first with an accelerated motion, till its increasing velocity comes to oppose a resistance equal to the force of attraction, or to the combined weight of the whole apparatus. After this counterpoise has taken place, there existing no longer any cause of acceleration, the parachute should descend uni¬ formly with its acquired rapidity. This perfect equili¬ brium will not, however, be attained at once. The accu¬ mulation of swiftness produced by the unceasing operation of gravity, is not immediately restrained by the corre¬ sponding increased resistance of the atmosphere. The motion of a parachute must hence, for some short time, be subject to a sort of interior oscillation, alternately accele¬ rating and retarding. It first shoots beyond the terminal velocity, and then, suffering greater resistance, it relaxes, and contracts within the just limits. This unequal and undulating progress which a parachute exhibits subse-. quently to the commencement of its fall, is calculated to excite disproportionate alarms of insecurity and danger, efts The terminal velocity of a parachute, or the uniform sequently the length of fall which would occasion the same shock, is ©•/ or very nearly Thus, if the parachute had thirty feet in diameter, and weighed, to- 26 getherwith its appended load, 225 pounds; then^- ^225 or.v 'rmu -26 * “ 30 X 15 = — 15 X 15 ri 13 feet, or the velocity with which it would strike the ground; and (rl^T 225 = \120/ velocity to which its motion tends, would, according to theory, be equal, if its surface were flat, to the velocity that a heavy body must acquire in falling through the al¬ titude of a column of air incumbent on that surface, and having, under the usual circumstances, the same weight as the whole apparatus. But we have already seen, that a cylinder of air, one foot in diameter and height, weighs only, in ordinary cases, the seventeenth part of a pound avoirdupois. Wherefore, if the square of the diameter of a parachute be divided by 17, the quotient will give the number of pounds equivalent to the weight of an atmo¬ spheric column of one foot; and the weight of the appara¬ tus being again divided by this quotient, the result will ex¬ press the entire altitude of an equiponderant column. Of this altitude, the square root multiplied by 8 will denote the final velocity, or that with which the parachute must strike the ground. Suppose, for example, that the dia¬ meter of the parachute were 25 feet; then 25 x 25 = 625; and this, divided by 17, gives 36j-|. Consequently, if the parachute with its load weighed only 36j-^ pounds, the shock received at the surface of the earth would be precisely the same as that which is felt in dropping from an elevation of one foot. Had the weight of the appara¬ tus, therefore, been four times greater, or 14)7^ pounds, the shock sustained would be the same as that from a fall of four feet; which is near the limit, perhaps, of what a person can bear without suffering injury from the violence of concussion. The velocity of descent, on this latter supposition, would be 8 ^/4, or sixteen feet each second. But the actual resistance of the air is rather greater than what theory would give; and it is besides augmented by the concavity of the opposing surface, which occasions an accumulation of the fluid. Let a denote the diameter of a parachute, and f the total weight of the apparatus abandoned to its gravity in the atmosphere ; if we take Dr feet, being the height from which a person dropping freely would receive the same shock. Since the resistance which air opposes to the passage of Celerity in a body is diminished by rarefaction, it is evident, that the the higher parachute disengaged from a balloon, in the more elevated reSlons- regions of the atmosphere, will at first acquire a greater velocity than it can afterwards maintain as it approaches the ground. Resuming the notation employed before, the ratio of the density of the air at the surface, and at any given height, being expressed by n : m‘ then the velocity of counterpoise at that elevation would be — I m .f,ov it would be equal to what is accumulated a ktj n, J 1 0 -I- ^2 /T* # in falling freely a height of —2- • — -J feet. It is the final velocity, however, that must be chiefly considered in parachutes, being what determines the shock sustained in alighting. The violence of the rushing through the air will seldom be attended with any serious inconvenience. If we suppose the mean velocity with which a parachute descends to be twelve feet each second, this will corre¬ spond to the rate of a mile in 7^ minutes ; not more than that of a very gentle trot. We are not told from what height Garnerin dropped; but if he took four minutes in his descent, it was probably about half a mile. The practice of aeronautics has not realized those ex¬ pectations of benefit to mankind which sanguine projectors were at first disposed to entertain. It was soon found, that a balloon, launched into the atmosphere, is abandoned, without guidance or command, to the mercy of the winds. To undertake to direct or impel the floating machine by any exertion of human strength, was evidently a chimeri¬ cal attempt. All the influence which the aeronaut really possesses consists in a very limited power of raising or depressing it, according to circumstances. He cannot hope to shape his course, unless by skilfully adapting his elevation to catch the prevailing currents. Almost the only purpose to which balloons have hither-Balloons to been applied with success, had for its object that of used in military reconnaissance. In the early part of the French war. revolutionary war, when ingenuity and science were so eagerly called into active service, a balloon, prepared under the direction of the Aerostatic Institute in the Polytechnic School, and intrusted to the command of two or three ex¬ perienced officers, was distributed to each of the republi¬ can armies. The decisive victory which General Jpurdan gained, in June 1794, over the Austrian forces in the plains of Fleurus, has been ascribed principally to the ac¬ curate information of the enemy’s movements before and during the battle, communicated by telegraphical signals from a balloon which was sent up to a moderate height in the air. The aeronauts, at the head of whom was the cele- 192 AERONAUTICS. Aeronau- brated Guyton-Morveau, mounted twice in the course of ^^^j^that day, and continued, about four hours each time, hovering in the rear of the army at an altitude of 1300 feet. In the second ascent, the enterprise being discovered by the enemy, a battery was opened against them ; but they soon gained an elevation above the reach of the cannon. Another balloon, constructed by the same skilful artist, M. Conte, was attached to the army sent on the memorable expedition to Egypt. What service it rendered the dar¬ ing invader in the wide plains and sandy deserts of Africa, we are not informed ; but, after the capitulation of Cairo, it was brought back, with the remains of the army, to France, and employed in the sequel, as we shall find, more innocently in philosophical research. These balloons, being calculated for duration, were of a more solid and perfect Method of construction than usual. Originally they were filled with them* hydrogen gas, obtained from the decomposition of water on a large scale. For this purpose, six iron cylinders had been fixed by masonry in a simple kind of furnace, each of their ends projecting, and covered with an iron lid. Two sets of metal tubes were also inserted, the one for convey¬ ing hot water, and the other for carrying off the gas which was formed. The cylinders being charged with iron-turn¬ ings, and brought to a red heat, the humidity was instantly converted into steam, and decomposed, the oxygen uniting with the iron, while the hydrogen gas was discharged, and made to deposit any carbonic gas that might adhere to it, by passing through a reservoir filled with caustic lye be¬ fore it entered the balloon. By this method there was procured, at a very moderate expense, and in the space of about four hours, a quantity of hydrogen gas sufficient to inflate a balloon of thirty feet in diameter. The ascents with balloons should appear to furnish the readiest means of ascertaining important facts in meteo¬ rology and atmospheric electricity, departments of science which are still unfortunately in their infancy. Some aeronauts have asserted that the magnetic needle ceased to traverse at very great elevations in the atmosphere; a statement which received some countenance from the ob¬ servations made by Saussure on the lofty summit of the Col du Geant, where that celebrated naturalist thought he had found the magnetic virtue to be diminished one fifth part. It has been pretended by others, that the air of the higher regions is not of the same composition as at the surface of the earth, and is, independently altogether of its rarity, less fitted for the purpose of respiration. To determine these, and other relative points, was, therefore, an object interesting to the progress of physical science. Scientific A few years since, two young and ardent French philoso- BioT11°/ P^ers, MM. Biot and Gay-Lussac, proposed to undertake Gay Lus aerial ascent, in order to examine the magnetic force sac.’ ' great elevations, and to explore the constitution of the higher atmosphere and its electrical properties. For such a philosophical enterprise they were eminently qualified, having been educated together at the Polytechnic School, and both of them deeply versed in mathematics; the for¬ mer indulging in a wide range of study, and the latter con¬ centrating his efforts more on chemistry and its applica¬ tion to the arts. Their offer to government was seconded by Berthollet and Laplace, and the celebrated chemist Chaptal, then minister of the interior, gave it his patronage and warm support. The balloon which had once visited Egypt was delivered to the custody of Biot and Gay- Lussac ; and the same artist who constructed it was, at the public expense, ordered to refit and prepare it under their direction. Besides the usual provision of barometers, ther¬ mometers, hygrometers, and electrometers, they had two compasses, and a dipping-needle, with another fine needle, carefully magnetized, and suspended by a very delicate silk thread, for ascertaining by its vibrations the force of magnetic attraction. To examine the electricity of the1' different strata of the atmosphere, they carried several metallic wires, from sixty to three hundred feet in length and a small electrophorus feebly charged. For galvanic experiments they had procured a few discs of zinc and copper, with some frogs; to which they added insects and birds. It was also intended to bring down a portion of air from the higher regions, to be subjected to a chemical analysis; and for this purpose a flask, carefully exhaust¬ ed, and fitted with a stop-cock, had been prepared. The balloon was placed in the garden of the Conserva¬ toire des Arts, or Repository of Models, formerly the Con¬ vent of St Martin ; and no pains were spared by Conte in providing whatever might contribute to the greater safety and convenience of the voyagers. Every thing being now ready for their ascent, these adventurous philosophers, in the presence of a few friends, embarked in the car at ten o’clock in the morning of the 23d of August 1804. The barometer was then at 30T3 inches, the thermometer at 61-7° on Fahrenheit’s scale, and Saussure’s hygrometer pointed at 80-8o, or very near the limit of absolute hu- midity. They rose with a slow and imposing motion. Their feelings were at first absorbed in the novelty and magnificence of the spectacle which opened before them; and their ears were saluted with the buzz of distant gra- tulations, sent up from the admiring spectators. In a few minutes they entered the region of the clouds, which seemed like a thin fog, and gave them a slight sensation of humidity. The balloon had become quite inflated, and they were obliged to let part of the gas escape, by opening the upper valve; at the same time, they threw out some ballast, to gain a greater elevation. They now shot through the range of clouds, and reached an altitude of about 6500 English feet. These clouds, viewed from above, had the ordinary whitish appearance ; they all oc¬ cupied the same height, only their upper surface seemed marked with gentle swells and undulations, exactly re¬ sembling the aspect of a wide plain covered with snow. MM. Biot and Gay-Lussac now began their experimen-T tal operations. The magnetic needle was attracted, asPe usual, by iron; but they found it impossible at this time0"' to determine with accuracy its rate of oscillation, owing to a slow rotatory motion with which the balloon was affected. In the meanwhile, therefore, they made other observations. A Voltaic pile, consisting of twenty pairs of plates, exhibited all its ordinary effects,—gave the pungent taste, excited the nervous commotion, and occa¬ sioned the decomposition of water. By rejecting some more ballast, they had attained the altitude of 8940 feet, but afterwards settled to that of 8600 feet. At this great elevation, the animals which they carried with them ap¬ peared to suffer from the rarity of the air. They let off a violet bee, which flew away very swiftly, making a hum¬ ming noise. The thermometer had fallen to 56-4° by Fahrenheit, yet they felt no cold, and were, on the con¬ trary, scorched by the sun’s rays, and obliged to lay aside their gloves. Both of them had their pulses much acce¬ lerated : that of Biot, which generally beat seventy-nine times in a minute, was raised to one hundred and eleven; while the pulse of his friend Gay-Lussac, a man of a less robust frame, was heightened from sixty to eighty beats in the minute. Notwithstanding their quickened pulsation, however, they experienced no sort of uneasiness, nor any difficulty in breathing. What perplexed them the most was the difficulty ofM observing the oscillations of a delicately suspended mag'0,*1 netic needle. But they soon remarked, on looking atten-1*0 irds nC' ited : ist fight} AERONAUTICS. 193 Aen iu- lively down upon the surface of the conglomerated clouds, r ti' that the balloon slowly revolved, first in one direction, and jr‘vw* then returned the contrary way. Between these opposite motions there intervened short pauses of rest, which it was necessary for them to seize. Watching, therefore, the moments of quiescence, they set the needle to vibrate, but were unable to count more than five, or very rarely ten oscillations. A number of trials, made between the alti¬ tudes of 9500 and 13,000 feet, gave 1" for the mean length of an oscillation, while at the surface of the earth it required 1 to perform each oscillation. A difference so very minute as the hundred and fortieth part could be imputed only to the imperfection of the experiment; and it was hence fairly concluded, that the force of magnetic attraction had in no degree diminished at the greatest ele¬ vation which they could reach. The direction of this force, too, seemed, from concurring circumstances, to have continued the same; though they could not depend on observations made in their vacillating car with so delicate an instrument as the dipping needle. At the altitude of 11,000 feet they liberated a green linnet, which flew away directly; but, soon feeling itself abandoned in the midst of an unknown ocean, it returned and settled on the stays of the balloon. Then mustering fresh courage, it took a second flight, and dashed down¬ wards to the earth, describing a tortuous yet almost perpen¬ dicular track. A pigeon which they let off under similar circumstances afforded a more curious spectacle. Placed on the edge of the car, it rested a while, measuring as it were the breadth of that unexplored sea which it designed to traverse: now launching into the abyss, it fluttered ir¬ regularly, and seemed at first to try its wings in the thin element; till, after a few strokes, it gained more confi¬ dence, and, whirling in large circles or spirals, like the birds of prey, it precipitated itself towards the mass of ex¬ tended clouds, where it was lost from sight. It was difficult, in those lofty and rather humid regions, to make electrical observations ; and the attention of the scientific navigators was besides occupied chiefly by their rnagnetical experiments. However, they let down from the car an insulated metallic wire of about 250 feet in length, and ascertained, by means of the electrophorus, that the upper end indicated resinous or negative electri¬ city. This experiment was several times repeated; and it seemed to corroborate fully the previous observations of Saussure and Volta relative to the increase of electricity met with in ascending the atmosphere. The diminution of temperature in the higher regions was found to be less than what is generally experienced at the same altitude on mountains. Thus, at the eleva¬ tion of 12,800 feet, the thermometer was at 51° by Fah¬ renheit, while it stood as low as 63^° at the observatory; being only a decrement of one degree for each 1000 feet of ascent. This fact corresponds with the observations made by former aeronauts, and must have been produced, ve conceive, by the operation of two distinct causes, first, the rays from the sun, not being enfeebled by pass¬ ing through the denser portion of the atmosphere, would act with greater energy on the balloon and its car, and consequently affect the thermometer placed in their vici- fy. Next, the warm current of air, which during the nay rises constantly from the heated surface of the ground, must augment the temperature of any body which is exposed to its influence. During the night, on the con- the upper strata of the atmosphere would be found co der, we presume, than the general standard, owing to ie copious descent of chill portions of air from the high¬ est regions. , & The hygrometer, or rather hygroscope, of Saussure, ad- VOL.

At the elevation of 13,000 tics- feet it had changed from 80-8° to 30°. But still the con- elusion, that the air of the higher strata is drier than that of the lower, we are inclined to consider as fallacious. In fact, the indications of the hygroscope depend on the re¬ lative attraction for humidity possessed by the substance employed, and the medium in which it is immersed. But air has its disposition to retain moisture always augmented by rarefaction, and consequently such alteration alone must materially affect the hygroscope. The only accu¬ rate instrument for ascertaining the condition of air with respect to dryness is founded on a property of evapora¬ tion. But we shall afterwards have occasion to discuss this subject at due length. The ballast now being almost quite expended, it was Their resolved to descend. The aeronauts therefore pulled the descent, upper valve, and allowed part of the hydrogen gas to escape. They dropped gradually, and when they came to the height of 4000 feet, they met the stratum of clouds, extending horizontally, but with a surface heaved into gentle swells. When they reached the ground, no people were near them to stop the balloon, which dragged the car to some distance along the fields. From this awkward and even dangerous situation they could not extricate themselves without discharging the whole of their gas, and therefore giving up the plan of sending M. Gay-Lussac alone to explore the highest regions. It has been reported that his companion M. Biot, though a man of activity and not deficient in personal courage, was so much overpowered by the alarms of their descent, as to lose for the time the entire possession of himself. The place where they alighted, at half-past one o’clock, after three hours and a half spent in the midst of the atmo¬ sphere, was near the village of Meriville, in the depart¬ ment of the Loiret, and about fifty miles from Paris. It was the desire of several philosophers at Paris, that M. Gay-Lussac should mount a second time, and repeat the different observations at the greatest elevation he could attain. Experience had instructed him to reduce his apparatus, and to adapt it better to the actual circum¬ stances. As he could only count the vibrations of the magnetic needle during the very short intervals which oc¬ curred between the contrary rotations of the balloon, he preferred one of not more than six inches in length, which therefore oscillated quicker. The dipping needle was magnetized and adjusted by the ingenious M. Coulomb. To protect the thermometer from the direct action of the sun, it was inclosed within two concentric cylinders of pasteboard covered with gilt paper. The hygrometers, constructed on Richer’s mode, with four hairs, were shel¬ tered nearly in the same way. The two glass flasks in¬ tended to bring down air from the highest regions of the atmosphere had been exhausted till the mercurial gage stood at the 25th part of an inch, and their stop-cocks were so perfectly fitted, that, after the lapse of eight days, they still preserved the vacuum. These articles, with two barometers, were the principal instruments which M. Gay- Lussac took with him. The skill and intelligence of the artist had been exerted in further precautions for the safety of the balloon. At forty minutes after nine o’clock on the morning ofGay-Lus- the 15th of September, the scientific voyager ascended, as sac ,ascends before, from the garden of the Repository of Models. The a«ain barometer then stood at 30-66 English inches, the ther- one‘ mometer at 82° by Fahrenheit, and the hygrometer at 571°. The sky was unclouded, but misty. Scarcely had the observer reached the height of 3000 feet, when he observed spread below him, over the whole extent of the 2 B 194 AERONAUTICS. magne tism. ture. Aeronau- atmosphere, a thin vapour, which rendered the distant ob- tics. jects very indistinct. Having gained an altitude of 9950 feet, he set his needle to vibrate, and found it to perform twenty oscillations in 83", though it had taken 84'33" to make the same number at the surface, of the earth. At His obser- the height of 12,680 feet he discovered the variation of vations in compass to be precisely the same as below ; but with macme- the pains he could take, he was unable to determine with sufficient certainty the dip of the needle. M. Gay- Lussac continued to prosecute his other experiments with the same diligence, and with greater success. At the al¬ titude of 14,480 feet he found that a key, held in the magnetic direction, repelled with its lower end, and at¬ tracted with its upper end, the north pole of the needle of a small compass. This observation was repeated, and with equal success, at the vast height of 20,150 feet ; a clear proof that the magnetism of the earth exerts its influence at remote distances. He made not fewer than fifteen trials at different altitudes, with the oscillations of his finely suspended needle. It was generally allowed to vi¬ brate twenty or thirty times. I he mean result gives 4*22" for each oscillation, while it was 4-216" at the sur¬ face of the earth ; an apparent difference so extremely small, as to be fairly neglected. Successive During the whole of his gradual ascent, he noticed, at (iecre- g-f^ intervals, the state of the barometer, the thermome- nients of an(j the hygrometer. Of these observations, amount- tempera- .n all to twenty.one, he has given a tabular view. We regret, however, that he has neglected to mark the times at which they were made, since the results appear to have been very considerably modified by the progress of the day. It would likewise have been desirable to have compared them with a register noted every half hour at the Observatory. From the surface of the earth to the height of 12,125 feet, the temperature of the at¬ mosphere decreased regularly from 82° to 47-3° by Fah¬ renheit’s scale. But afterwards it increased again, and reached to 53-6°, at the altitude of 14,000 feet; evidently owing to the influence of the warm currents of air which, as the day advanced, rose continually from the heated ground. From that point the temperature diminished, with only slight deviations from a perfect regularity. At the height of 18,636 feet the thermometer subsided to 32-9°, on the verge of congelation; but it sunk to 14'9° at the enormous altitude of 22,912 feet above Paris, or 23,040 feet above the level of the sea, the utmost limit of the balloon’s ascent. From these observations no conclusive inference, we son of tliese think, can be drawn respecting the mean gradation of cold t:ons'Va" which is maintained in the higher regions of the atmo¬ sphere ; for, as we have already remarked, the several stra¬ ta are during the day kept considerably above their per¬ manent temperature by the hot currents raised from the surface through the action of the sun’s rays. If we adopt the formula given by Professor Leslie at the end of his Elements of Geometry, which was the result of some ac¬ curate and combined researches, the diminution of tem¬ perature corresponding to the first part of the ascent, or 12,125 feet, ought to be forty degrees of Fahrenheit. It was actually 34-7°, and would no doubt have approached to 40°, if the progressive heating of the surface, during the interval of time, were taken into the account. In the next portion of the voyage, from the altitude of 14,000 to that of 18,636 feet, or the breadth of 4636 feet, the de¬ crement of temperature according to the formula should only have been 16^°, instead of 20*7°, which was really marked; a proof that the diurnal heat from below had not yet produced its full effect at such a great height. In the last portion of the balloon’s ascent, from 18,636 feet to Compari- 22,912, a range of 4276 feet, the decrease of heat ought Ai to be 15^°, and it was actually 18° ; owing most probably to the same cause, or the feebler influence which warmH currents of air from the surface exert at those vast eleva- tions. Taking the entire range of the ascent, or 22,912 feet, the diminution of temperature according to the same formula would be for the gradation of temperature in as¬ cending the atmosphere 85-4°. The decrease actually observed would be 67-1°, which might be raised to 80°, if we admit the very probable supposition, that the sur- face of the earth had become heated from 82° to 94-9° during the interval between ten o’clock in the morning and near three in the afternoon, when the balloon floated at its greatest elevation. After making the fair allowances, therefore, on account of the operation of deranging causes, the results obtained by M. Gay-Lussac, for the gradation of temperature in the atmosphere, appear, on the whole, to agree very nearly with those derived from the formula which theory, guided by delicate experiments, had before assigned. This gra¬ dation is evidently not uniform, as some philosophers have assumed; but proceeds with augmented rapidity in the more elevated regions. The same conclusion results from a careful inspection of the facts which have been stated by other observers. The hygrometers, during the ascent of the balloon, held In a progress not quite so regular, but tending obviously to-tin wards dryness. At the height of 9950 feet they had11" changed from 57-5° to 62°; from which point they con-^' tinued afterwards to decline, till they came to mark 27-5°, at the altitude of 15,190 feet. From this inferior limit the hygrometers advanced again, yet with some fluctua¬ tions, to 35-1°, which they indicated at the height of 18,460 feet. Above this altitude the variation was slight, though rather inclining to humidity. There can exist no doubt, however, that, allowing for the influence of the prevailing cold, the higher strata of the atmosphere must be generally drier than the lower, or capable of retaining, at the same temperature, a larger share of moisture. At the altitude of 21,460 feet M. Gay-Lussac openedb one of his exhausted flasks ; and, at that of 21,790 feet, ^ the other. The air rushed into them through the narrow“ aperture, with a whistling noise. He still rose a little higher, but, at eleven minutes past three o’clock, he had attained the utmost limit of his ascent, and was then ,22,912 feet above Paris, or 23,040 feet, being more than four miles and a quarter, above the level of the sea. The air was now more than twice as thin as ordinary, the ba¬ rometer having sunk to 12-95 inches. From that stupen¬ dous altitude, sixteen hundred feet above the summit of the Andes, more elevated than the loftiest pinnacle of our globe, and far above the heights to which any mortal had ever soared, the aerial navigator might have indulged the feelings of triumphant enthusiasm. But the philosopher, in perfect security, was more intent on calmly pursuing his observations. During his former ascent, he saw the fleecy clouds spread out below him, while the canopy of heaven seemed of the deepest azure, more intense than Prussian blue. This time, however, he perceived no clouds gathered near the surface, but remarked a range of them stretching, at a very considerable height, over his head: the atmosphere, too, wanted transparency, and had a dull, misty appearance. The different aspect of the sky was probably owing to the direction of the wind, which blew from the north-north-west in his first voyage, but in his second from the south-east. While occupied with experiments at this enormous ele-o vation, he began, though warmly clad, to suffer from ex- AERONAUTICS. iron - cessive cold, and his hands, by continual exposure, grew 195 • 7 # , J , 1 7 O v ” tics benumbed. He felt likewise a difficulty in breathing, and pvVhis pulse and respiration were much quickened. His throat became so parched from inhaling the dry attenu¬ ated air, that he could hardly swallow a morsel of bread; but he experienced no other direct inconvenience from his situation. He had indeed been affected, through the whole of the day, with a slight headache, brought on by the preceding fatigues and want of sleep; but though it conti¬ nued without abatement, it was not increased by his ascent, ides The balloon was now completely distended, and not Jt- more than 33 pounds of ballast remained: it began to drop, and M. Gay-Lussac, therefore, only sought to regulate its descent. It subsided very gently, at the rate of about a mile in eight minutes; and after the lapse of thirty-four minutes, or at three quarters after three o’clock, the an¬ chor touched the ground, and instantly secured the car. The voyager alighted with great ease near the hamlet of St Gourgon, about sixteen miles north-west from Rouen. The inhabitants flocked around him, offering him assist¬ ance, and eager to gratify their curiosity. [ana As soon as he feached Paris, he hastened to the labo- f ratory of the Polytechnic School, with his flasks, contain- a'r ing air of the higher regions, and proceeded to analyze it in the presence of Thenard and Cresset. Opened under water, the liquid rushed into them, and apparently half filled their capacity. The transported air was found, by a very delicate analysis, to contain exactly the same propor¬ tions as that collected near the surface of the earth, every 1000 parts holding 215 of oxygen. From concurring ob¬ servations, therefore, we may conclude that the atmo¬ sphere is essentially the same in all situations, jad The ascents performed by MM. Biot and Gay-Lussac are memorable, for being the first ever undertaken solely r' for objects of science. It is impossible not to admire the intrepid coolness with which they conducted those expe¬ riments, operating, while they floated in the highest re¬ gions of the atmosphere, with the same composure and precision as if they had been quietly seated in their cabi¬ nets at Paris. Their observations on the force of terres¬ trial magnetism show most satisfactorily its deep source and wide extension. The identity of the constitution of the atmosphere to a vast altitude was likewise ascer¬ tained. The facts noted by Gay-Lussac, relative to the state of the thermometer at different heights, appear ge¬ nerally to confirm the law which theory assigns for the gradation of temperature in the atmosphere : but many interesting points were left untouched by this philosopher. We are sorry that he had not carried with him the cycmo- mter, which enabled Saussure to determine the colour of the sky on the summits of the Swiss mountains. Still more we regret that he was not provided with an hygro¬ meter and a photometer, of Leslie’s construction. These delicate instruments could not have failed, in his hands, to furnish important data for discovering the relative dry¬ ness and transparency of the different strata of air. It would have been extremely interesting, at such a tremen¬ dous height, to have measured with accuracy the feeble hght reflected from the azure canopy of heaven, and the intense force of the sun’s direct rays, and hence to have determined what portion of them is absorbed in their pas¬ sage through the lower and denser atmosphere. Since that time numerous ascents have been per- tormed in different countries, generally by adventurers guided by no philosophical views, nor leading to any •ic va uahle results. It would therefore be superfluous to ;s Fecount such repeated attempts. Balloons have at different times been thought capable 0 useful application. It has been even proposed to em¬ ploy their power of ascepsion as a mechanical force. This Aeronau- might be rendered sufficient, it was believed, to raise wa- tics, ter from mines, or to transport obelisks, and place them'w^v^-/' on great elevations. We can easily imagine situations where a balloon could be used with advantage ; such as to raise, without any scaffolding, a cross or a vane to the top of a high spire. But the power would then be purchased at a very disproportionate expense. It would require pounds of iron, or 6 of zinc, with equal quantities of sul¬ phuric acid, to yield hydrogen gas sufficient to raise up the weight of one pound. The proposal of employing balloons in the defence and attack of fortified places appears truly chimerical. They have rendered important service, however, in reconnoitring the face of a country, and communicating military sig¬ nals ; and it is rather surprising that a system, which promised such obvious benefits, has not been carried much farther. But to a skilful and judicious application of balloons, we Their ap- may yet look for a most essential improvement of the in-plication fant science of meteorology. Confined to the surface ofproposed this globe, we have no direct intimation of what passes infor tIie iln- the lofty regions of the atmosphere. All the changes 0fP™vement weather, which appear so capricious and perplexing, pro-pol^e°" ceed, no doubt, from the combination of a very few simple ’ causes. Were the philosopher to penetrate beyond the seat of the clouds, examine the circumstances of their formation, and mark the prevailing currents, he would probably remove in part the veil that conceals those mighty operations. It would be quite practicable, we conceive, to reach an elevation of seven miles, where the air would be four times more attenuated than ordinary. A silk balloon, of forty feet diameter, if properly con¬ structed, might be sufficient for that enormous ascent, since its weight would only be 80 pounds, while its buoy¬ ant force, though not more than a quarter filled with hy¬ drogen gas, would amount to 533^ leaving 453^ pounds for the passenger and the ballast. The balloon could be safely charged, indeed, to the third part of its capacity, on account of the contraction which the gas would afterwards suffer from the intense cold of the upper regions ; and this gives it an additional buoyancy of 177| pounds. The voyager would not, we presume, suffer any serious incon¬ venience from breathing the very thin air. The animal frame adapts itself with wonderful facility to external cir¬ cumstances. Perhaps the quickened pulse and short re¬ spiration, which some travellers have experienced on the summits of lofty mountains, should be attributed chiefly to the suddenness of their transition, and the severity of the cold. The people of Quito live comfortably 9560 feet above the level of the sea ; and the shepherds of the ham¬ let of Antisana, the highest inhabited spot in the known world, who breathe, at an elevation of 13,500 feet, air that has only three-fifths of the usual density, are nowise de¬ ficient in health or vigour. But the intenseness of the cold is probably what the resolute observer would have most to dread, at the height of seven miles. This decrease of temperature, perhaps equal to 148 degrees, might ex¬ tend below the point at which mercury freezes. Yet se¬ veral circumstances tend to mitigate such extreme cold, and proper clothing might enable an experimenter for a short time to resist its effects. Much could be done, however, without risk or material expense. Balloons from fifteen to thirty feet in diameter, and carrying register thermometers and barometers, might be capable of ascending alone to altitudes between eight and twelve miles. Dispatched from the centres of the great continents, they would not only determine the ex¬ treme gradation of cold, but indicate by their flight the 1 196 iE S C Aerschot direction of the regular and periodic winds which doubtless II. obtain in the highest regions of the atmosphere. But we /^"^^’will not enlarge. In some happier times, such experiments may be performed with the zealous concurrence of different governments ;—when nations shall at last become satisfied with cultivating the arts of peace, instead of wasting their energies in sanguinary, destructive, and fruitless wars, (b.) In Plate II. there is a view of the principal balloons. The figure in the centre represents the shape of the gores AERSCHOT, a fortified city in the Netherlands, on the river Dander, 7 miles from Louvain, and 20 from Antwerp, containing 2750 inhabitants. TERUGINOUS, an epithet given to such things as re¬ semble or partake of the nature of the rust of copper. iERUGO, in Natural History, properly signifies the rust of copper, whether natural or artificial. The former is found about copper mines, and the latter, called verdi¬ gris, made by corroding copper plates with acids. iERUSCATORES, in Antiquity, a kind of strolling beg¬ gars, not unlike gypsies, who drew money from the credu¬ lous by fortune-telling, &c. It was also a denomination given to griping exactors, or collectors of the revenue. The Galli, or priests of Cybele, were called ceruscatores tnagnce matris ; and yr~?aywrai, from their begging in the streets ; to which end they had little bells to draw people’s atten¬ tion, similar to some orders of mendicants abroad. AERZEELE, a town of 2809 inhabitants, in the arron- dissement of Kortryk, and province of West Flanders. AERZEN, a bailiwick in the province of Kalenberg, in the kingdom of Hanover, with 1 market town, 19 villages, 852 houses, and 4895 inhabitants. The extent is about 28,400 acres. The chief town of the bailiwick has the same name. It contains 159 houses, and 901 inhabitants. iES uxorium, in Antiquity, a sum paid by bachelors, as a penalty for living single to old age. This tax for not marrying seems to have been first imposed in the year of Rome 350, under the censorship of M. Furius Camillus and M. Posthumus. At the census, or review of the people, each person was asked, Et tu ex animi sententia uxorem habes liberorum qucerendorum causa ? He who had no wife was hereupon fined after a certain rate, called ces uxorium. AEs per et libram was a formula in the Roman law, whereby purchases and sales were ratified. Originally the phrase seems to have been only used in speaking of things sold by weight, or by the scales; but it afterwards was used on other occasions. Hence even in adoptions, as there was a kind of imaginary purchase, the formula there¬ of expressed, that the person adopted was bought per ces et libram. AESCHINES, an Athenian, a Socratic philosopher, the son of Charinus, a sausage-maker. He was continually with Socrates; which occasioned this philosopher to say, that the sausage-maker’s son was the only person who knew how to pay a due regard to him. It is said that poverty obliged him to go to Sicily to Dionysius the tyrant; and that he met with great contempt from Plato, but was ex¬ tremely well received by Aristippus, to whom he showed some of his dialogues, and received from him a handsome reward. He would not venture to profess philosophy at Athens, Plato and Aristippus being in such high esteem; but he opened a school, in which he taught philosophy, to maintain himself. He afterwards wrote orations for the forum. Phrynicus, in Photius, ranks him amongst the A3 S C for forming the cloth into a globular shape. AE, the length of the gore, is equal to the half of the circumference of the globe ; BC, the breadth, is the same proportional part ^ of the circumference as the number of gores which it re-^ quires to form the sphere. The figures between CB and A denote the breadths of the half-gore, at equal distances from the centre ; the breadth BD at the centre being taken equal to 1, and the others in decimals. In this manner it is easy to construct an exact pattern of the gores, all which, being united, will form a true sphere. 'Jim best orators, and mentions his orations as the standard of the pure Attic style. Hermogenes has also spoken very highly of him. He wrote, besides, several Dialogues, of which there are only three extant: 1. Concerning virtue, whether it can be taught. 2 Eryxias, or Erasistratus; concerning riches, whether they are good. 3. Axiochus; concerning death, whether it is to be feared. M. le Clerc has given a Latin translation of them, with notes and several dissertations, entitled Silvce Philologicce. JEschines, a celebrated Grecian orator, was born at Athens 327 years before the Christian era. According to his own account, he was of distinguished birth ; according to that of Demosthenes, he was the son of a courtesan, and a humble performer in a company of comedians. But whatever was the true history of his birth and early life, his talents, which were considerable, procured him great applause, and enabled him to be a formidable rival to Demosthenes himself. The two orators, inspired pro¬ bably with mutual jealousy and animosity, became at last the strenuous leaders of opposing parties. iEschines was accused by Demosthenes of having received money as a bribe, when he was employed on an embassy to Philip of Macedon. He indirectly retaliated the charge by bringing an accusation against Ctesiphon, the friend of Demosthenes, for having moved a decree, contrary to the laws, to confer on Demosthenes a golden crown, as a mark of public ap¬ probation. A numerous assembly of judges and citizens met to hear and decide the question. Each orator employ¬ ed all his powers of eloquence; but Demosthenes, with su¬ perior talents, and with justice on his side, was victorious; and iEschines was sent into exile. The resentment of De¬ mosthenes was now softened into generous kindness; for when ZEschines was going into banishment, he requested him to accept of a sum of money; which made him ex¬ claim, “ How do I regret leaving a country where I have found an enemy so generous, that I must despair of ever meeting with a friend who shall be like him !” ZEschines opened a school of eloquence at Rhodes, which was the place of his exile ; and he commenced his lectures by reading to his audience the two orations which had been the cause of his banishment. His own oration received great praise, but that of Demosthenes was heard with boundless applause. In so trying a moment, when vanity must be supposed to have been deeply wounded, with a noble generosity of sentiment, he said, “ What would you have thought if you had heard him thunder out the words himself.”—iEschines afterwards removed to Samos, where ; he died in the 75th year of his age. Three of his orations only are extant. His eloquence is not without energy, but it is diffuse and ornamented, and more calculated to please than to move the passions. ZESCHYLUS, the tragic poet, was born at Athens. The time of his birth is not exactly ascertained. Some suppose that it was in the 65th, others in the 70th Olym¬ piad ; but according to Stanley, who follows the Arunde- .ESC ?lus lian marbles, he was born in the 68d Olympiad. He was 5 the son of Euphorion, and brother to Cynsegirus and Amy- ^cjla- njas, who distinguished themselves in the battle of Mara- 1 I'f thon and the sea-fight of Salamis, at which engagements ^gchylus was likewise present. In this last action, ac¬ cording to Diodorus Siculus, Amynias, the youngest of the three brothers, commanded a squadron of ships, and fought with so much conduct and bravery, that he sunk the admiral of the Persian fleet, and signalized himself above all the Athenians. To this brother our poet was, upon a particular occasion, obliged for saving his life, ^lian relates, that Aeschylus, being charged by the Athe¬ nians with certain blasphemous expressions in some of his pieces, was accused of impiety, and condemned to be stoned to death: they were just going to put the sen¬ tence in execution, when Amynias, with a happy presence of mind, throwing aside his cloak, showed his arm without a hand, which he had lost at the battle of Salamis in de¬ fence of his country. This sight made such an impression on the judges, that, touched with the remembrance of his valour, and with the friendship he showed for his brother, they pardoned iEschylus. Our poet, however, resented the indignity of this prosecution, and resolved to leave a place where his life had been in danger. He became more determined in this resolution when he found his pieces less pleasing to the Athenians than those of Sophocles, though a much younger writer. Some affirm, that iEschy- lus never sat down to compose but when he had drunk liberally. He wrote a great number of tragedies, of which there are but seven remaining ; and notwithstanding the sharp censures of some critics, he must be allowed to have been the father of the tragic art. In the time of Thespis there was no public stage to act upon, the strollers driving about from place to place in a cart. iEschylus ; furnished his actors with masks, and dressed them suit¬ ably to their characters. He likewise introduced the bus¬ kin, to make them appear more like heroes. The ancients gave Aischylus also the praise of having been the first who removed murders and shocking sights from the eyes of the spectators. He is said likewise to have lessened the number of the chorus. M. Le Fevre has observed, that AEschylus never represented women in love in his tragedies, which, he says, was not suited to his genius; but in representing a woman transported with fury he was incomparable. Longinus says, that AEschylus has a noble boldness of expression, and that his imagination is lofty and heroic. It must be owned, however, that he affected pompous words, and that his sense is too often obscured by figures. This gave Salmasius occasion to say that he was more difficult to be understood than the Scripture itself. But notwithstanding these imperfections, this poet was held in great veneration by the Athenians, who made a public decree that his tragedies should be played after his death. He was killed in the 69th year of his age, by an eagle letting fall a tortoise upon his head as he was walking in the fields. He had the honour of a pompous funeral from the Sicilians, who buried him near the river Gela; and the tragedians of the country per¬ formed plays and theatrical exercises at his tomb. The best editions of AEschylus are those of Stanley, folio, Lond. 1663, with an excellent Latin translation and com¬ mentary ; and of Schiitz, in 3 vols. 8vo, Halle, 1782. AESCULAPIUS, in the Heathen Mythology, the god of physic, was the son of Apollo and the nymph Coronis. He was educated by the centaur Chiron, who taught him physic, by which means AEsculapius cured the most des- perate diseases. But Jupiter, enraged at his restoring to life Hippolytus, who had been torn in pieces by his own horses, killed him with a thunderbolt. According to Cicero, S O 197 there were three deities of this name: the first, the son .Escula- of Apollo, worshipped in Arcadia, who invented the probe pius and bandages for wounds; the second, the brother of !l Mercury, killed by lightning; and the third, the son of /EsoP- Arsippus and Arsinoe, who first taught the art of tooth- drawing and purging. At Epidaurus, AEsculapius’s statue was of gold and ivory, with a long beard, his head sur¬ rounded with rays, holding in one hand a knotty stick, and the other entwined with a serpent: he was seated on a throne of the same materials as his statue, and had a dog lying at his feet. The Romans crowned him with laurel, to represent his descent from Apollo; and the Phliasians represented him as beardless. The cock, the raven, and the goat, were sacred to this deity. His chief temples were at Pergamus, Smyrna, Trica, a city in Ionia, and the isle of Coos; in all which votive tablets were hung up, showing the diseases cured by his assistance. But his most famous shrine was at Epidaurus, where, every five years, games were instituted to him, nine days after the Isthmian games at Corinth. AESOP, the Phrygian, lived in the time of Solon, about the 50th Olympiad, under the reign of Crcesus, the last king of Lydia. As to genius and abilities, he was greatly indebted to nature; but in other respects not so fortunate, being born a slave and extremely deformed. St Jerome, speaking of him, says he was unfortunate in his birth, condition in life, and death; hinting thereby at his defor¬ mity, servile state, and tragical end. His great genius, however, enabled him to support his misfortunes; and in order to alleviate the hardships of servitude, he composed those entertaining and instructive fables which have ac¬ quired him so much reputation. He is generally supposed to have been the inventor of that kind of writing; but this is contested by several, particularly Quintilian, who seems to think that Hesiod was the first author of fables. AEsop, however, certainly improved this art to a very great degree; and hence it is that he has been accounted the author of this sort of productions; JEsopus auctor quam materiam reperit, Hanc egopolivi versibus senariis. Pii.-t.d. Mine is the task, in easy verse, The tales of iEsop to rehearse. The first master whom AEsop served was one Carasius Demarchus, an inhabitant of Athens; and there, in all probability, he acquired his purity in the Greek tongue. After him he had several masters, and at length came under a philosopher named Idmon or ladmon, who en¬ franchised him. After he had recovered his liberty, he soon acquired a great reputation amongst the Greeks; so that, according to Meziriac, the report of his wisdom having reached Crcesus, he sent to inquire after him, and engaged him in his service. He travelled through Greece, according to the same author, whether for his own plea¬ sure or upon the affairs of Crcesus is uncertain; and passing by Athens soon after Pisistratus had usurped the sovereign power, and finding that the Athenians bore the yoke very impatiently, he told them the fable of the frogs who petitioned Jupiter for a king. The images made use of by AEsop are certainly very happy inventions to instruct mankind: they possess all that is necessary to perfect a precept, having a mixture of the useful with the agreeable. “ AEsop the fabulist,” says Aulus Gellius, “ was deservedly esteemed wise, since he did not, after the manner of the philosophers, rigidly and imperiously dictate such things as were proper to be advised and persuaded; but framing entertaining and agreeable apologues, he thereby charms and captivates the human mind.” AEsop was put to death at Delphi. Plutarch tells us, that he came thither with a 198 A E T iE T H iEsop Aeth. great quantity of gold and silver, being ordered by Croesus to offer a sacrifice to Apollo, and to give a considerable , sum to each inhabitant; but a quarrel arising betwixt him and the Delphians, he sent back the money to Croesus; for he thought those for whom the prince designed it had rendered themselves unworthy of it. The inhabitants of Delphi brought an accusation of sacrilege against him; and pretending they had convicted him, threw him head¬ long from a rock. For this cruelty and injustice, we are told, they were visited with famine and pestilence; and con¬ sulting the oracle, they received for answer, that the god halia Netherlands, and province of Hainault, situated on the river Dender, about 20 miles south-west of Brussels. iETHALIA, or Ilua, in Ancient Geography, now Elba, pier. | an island on the coast of Etruria, in compass a hundred^ v\j miles, abounding in iron. It was so called from atiuXrj, smoke, which issued from the shops of V ulcan. iETHELSTAN, see Athelstan. iETHER is usually understood of a thin, subtile mat¬ ter or medium, much finer and rarer than air, which, commencing from the limits of our atmosphere, possesses the whole heavenly space. The word is Greek, ai^o, sup. designed this as a punishment for their treatment of posed to be formed from the verb aifciv, to burn, to flame; some of the ancients, particularly Anaxagoras, supposing it to be of the nature of fire. The philosophers cannot conceive that the largest part of the creation should be perfectly void; and therefore they fill it with a species of matter under the denomina¬ tion of cether. But they vary extremely as to the nature and character of this aether. Some conceive it as a body sui generis, appointed only to fill up the vacuities between the heavenly bodies, and therefore confined to the regions above our atmosphere. Others suppose it of so subtile and penetrating a nature as to pervade the air and other bodies, and to possess the pores and intervals thereof. Sat. iii. iEsop. They endeavoured to make an atonement, by rais ing a pyramid to his honour. iEsop, Clodius, a celebrated actor, who flourished about the 670th year of Rome. He and Roscius were contem¬ poraries, and the best performers who ever appeared upon the Roman stage; the former excelling in tragedy, the latter in comedy. Cicero put himself under their direc¬ tion, to perfect his action. TEsop lived in a most expen¬ sive manner, and at one entertainment is said to have had a dish which cost above L.800. This dish, we are told, was filled with singing and speaking birds, some of which cost near L.50. The delight which iEsop took in this sort of birds proceeded, as M. Bayle observes, from the 'Others deny the existence of any such specific matter, expense. He did not make a dish of them because they and think the air itself, by that immense tenuity and ex- could speak, according to the refinement of Pliny upon pansion it is found capable of, may diffuse itself through the this circumstance, this motive being only by accident, interstellar spaces, and be the only matter found therein, but because of their extraordinary price.

Some suppose it of an elementary nature, speak of this as a common practice of his; but others like other bodies, and only distinguished by its tenuity, mention his falling into this excess only on a particular and the other affections consequent thereon; which is the day, when he was treating his friends.

In fine, this same matter seems the primum mobile, the first source or spring of physical action in the R cs- modern system. The Cartesian aether is supposed not only to pervade, but adequately to fill, all the vacuities of bodies ; and thus to make an absolute plenum in the universe. But Sir Isaac Newton shows that the celestial spaces are void of all sensible resistance; and hence it follows, that the matter contained therein must be immensely rare, in regard the resistance of bodies is chiefly as their density: so that if the heavens were thus adequately fill¬ ed with a medium or matter, how subtile soever, they would resist the motion of the planets and comets much more than quicksilver or gold. But it has been supposed that what Newton has said of aether is to be considered only as a conjecture, and especially as no new proofs of its existence have been adduced since his time. The late discoveries in electricity have thrown great light upon this subject, and rendered it extremely proba¬ ble that the aether so often talked of is no other than the electric fluid, or solar light, which diffuses itself through¬ out the whole system of nature. ^ETHEREAL, AUthereus, something that belongs to, or partakes of, the nature of jEther.

The Chaldees placed an aethereal world between the empy- reum and the region of the fixed stars. Besides which, they sometimes also speak of a second aethereal world, meaning by it the starry orb; and a third aethereal world, by which is meant the planetary region. ETHIOPIA.

AETION, a celebrated painter, who left an excellent picture of Roxana and Alexander, which he exhibited at the Olympic games. It represents a magnificent chamber, where Roxana is sitting on a bed of a most splendid ap¬ pearance, which is rendered still more brilliant by her beauty. She looks downwards in a kind of confusion, being struck with the presence of Alexander standing be¬ fore her. A number of little Cupids flutter about, some holding up the curtain, as if to show Roxana to the prince, whilst others are busied in undressing the lady; some pull Alexander by the cloak, who appears like a young bashful bridegroom, and present him to his mis¬ tress. He lays his crown at her feet, being accompanied by Hephaestion, who holds a torch in his hand, and leans upon a youth, who represents Hymen. Several other little Cupids are represented playing with his arms: some carry his lance, stooping under so heavy a weight; others bear along his buckler, upon which one of them is seated, whom the rest carry in triumph; another lies in ambush in his armour, waiting to frighten the rest as they pass by. fhis picture gained Aetion so much reputation, that the president of the games gave him his daughter in marriage. ETIfES, or Eagle-stone, in Natural History, a flinty or crustated stone, hollow within, and containing a nuckus, which, on •shaking, rattles within. It was former¬ ly in repute for several extraordinary magical as well as medical powers; such as preventing abortion, discovering thieves, and other ridiculous properties. The word is T N 199 formed from afro;, eagle, the popular tradition being, that Aetius it is found in the eagle’s nest, whither it is supposed to II be carried while the female sits, to prevent her eggs from -®tna* being rotten. It is found in several parts. Near Trevoux,V^^V^^ in France, one can scarcely dig a few feet without finding considerable strata or beds of the coarser or ferruginous kind. They are originally soft, and of the colour of yel¬ low ochre. But the finest and most valued of all the eagle-stones are accidental states of one or other of our common pebbles. AETIUS, one of the most zealous defenders of Arian- ism, was born in Syria, and flourished about the year 336. After being servant to a grammarian, of whom he learned grammar and logic, he was ordained deacon, and at length bishop, by Eudoxus, patriarch of Constantinople. Aetius was banished into Phrygia on account of his religious opinions; but was recalled from exile on the accession of Julian, and was much esteemed by that emperor. He died, it is supposed, at Constantinople, about the year 366. St Epiphanius has preserved 47 of his propositions against the Trinity. His followers were called Aetians. Aetius, a famous physician, born at Amida in Meso¬ potamia, and the author of a work entitled Tetrabiblos, which is a collection from the writings of those physicians who went before him. He lived, according to Dr Freind, in the end of the fifth or the beginning of the sixth century. 1 Aetius, governor of Gallia Narbonensis in the reign of Valentinian III., forced the Franks who were passing into Gaul to repass the Rhine. He defeated the Goths, and routed Attila, king of the Huns, who invaded Gaul with an army of 700,000 men. But the emperor, jealous of the merit of this great man, killed him in 454, with his own hand, under the pretence that he had permitted the inva¬ sion of the Huns, after Attila’s defeat. ETNA, (in the Itineraries JEthana, supposed from aiQ'ji, to burn; according to Bochart, from athuna, a furnace, or cetuna, darkness), now Monte Gibello ; a vol¬ cano or burning mountain of Sicily, situated in Long. 15. E. Lat. 38. N. This mountain, famous from the remotest antiquity, both for its bulk and terrible eruptions, stands in the eastern part of the island, in a very extensive plain, called Val di Demona, from the notion of its being inhabited by devils, wTio torment the spirits of the damned in the bowels of this volcano.

They all agree that 200 JS T N A. iEtna. Crater de¬ scribed. this single mountain affords an epitome of the different climates throughout the whole world. Towards the foot it is extremely hot; farther up, more temperate; and grows gradually more and more cold the higher we as¬ cend. At the very top it is perpetually covered with snow : from thence the whole island is supplied with that article, so necessary in a hot climate, and without which, the natives say, Sicily could not be inhabited. So great is the demand for this commodity, that the bishop’s re¬ venues, which are considerable, arise from the sale of Mount ^Etna’s snow ; and he is said to draw L.1000 a year from one small portion lying on the north side of the mountain. Great quantities of snow and ice are likewise exported to Malta and Italy, making a considerable branch of commerce. The snow of iEtna, says Captain Smyth, is not only consumed in vast quantities all over the island, but forms an extensive article of commerce with Malta and Italy, to which places it is sent in such profusion as to be sold from a penny to threepence the pound, a rate which renders it accessible to the lower orders. In the middle of the snowy region stands the great crater, or mouth of iEtna. Sir William Hamilton describes the crater as a little mountain, about a quarter of a mile perpendicular, and very steep, situated in the middle of a gently inclining plain, of about nine miles in circumfer¬ ence. It is entirely formed of stones and ashes; and, as he was informed by several people of Catania, had been thrown up about 25 or 30 years before the time (1769) he visited Mount ./Etna. Before this mountain was thrown up, there was only a prodigiously large chasm or gulf in the middle of the above-mentioned plain ; and it has been remarked, that about once in 100 years the top of iEtna falls in ; which undoubtedly must be the case at certain periods, otherwise the mountain would continually increase in height. As this little mountain, though emitting smoke from every pore, appeared solid and firm, Sir William Hamilton and his companions went up to the very top. In the middle is a hollow, about two miles and a half in circumference, according to Sir William Hamilton ; three miles and a half, according to Mr Brydone ; and three or four, according to M. D’Orville. The inside is crusted over with salts and sulphur of different colours. It goes shelving down from the top, like an inverted cone; the depth, in Sir William Hamilton’s opinion, nearly corre¬ sponding to the height of the little mountain. From many places of this space issue volumes of sulphurous smoke, which being much heavier than the circumambient air, instead of ascending in it, roll down the side of the moun¬ tain, till, coming to a more dense atmosphere, it shoots off horizontally, and forms a large track in the air, accord¬ ing to the direction of the wind; which, happily for our tra¬ vellers^ carried it exactly to the side opposite to that on which they stood. In the middle of this funnel is the tre¬ mendous and unfathomable gulf, so much celebrated in all ages, both as the terror of this life and the place of punishment in the next. From this gulf continually issue terrible and confused noises, which in eruptions are in¬ creased to such a degree as to be heard at a prodigious distance. Its diameter is probably very different at dif¬ ferent times; for Sir William Hamilton observed, by the wind clearing away the smoke from time to time, that the inverted hollow cone was contracted almost to a point; while M. D’Orville and Mr Brydone found the opening very large. Both Mr Brydone and Sir William Hamilton found the crater too hot to descend into it; but M. D’Or¬ ville was bolder; and accordingly, he and his fellow-tra¬ veller, fastened to ropes which two or three men held at a distance tor fear of accidents, descended as near as pos¬ sible to the brink of the gulf; but the small flames and smoke which issued from it on every side, and a greenish sulphur, and pumice stones, quite black, which covered M the margin, would not permit them to come so near as to have a full view. They only saw distinctly, in the middle a mass of matter which rose in the shape of a cone, to the5 height of above 60 feet, and which towards the base, as far as their sight could reach, might be 600 or 800 feet. While they were observing this substance, some motion was perceived on the north side, opposite to that whereon they stood; and immediately the mountain began to send forth smoke and ashes. This eruption was preceded by a sensible increase of its internal roarings; which, however did not continue, but, after a moment’s dilatation, as if to give it vent, the volcano resumed its former tranquillity; but as it was bj no means proper to make a long stay in such a place, our travellers immediately returned to their attendants. The top of ./Etna being above the common region oD’i^J vapours, the heavens appear with exceeding great splen-1’1 ial dour. Mr Brydone and his company observed, as they1" 1 ascended in the night, that the number of stars seemed to be indefinitely increased, and the light of each of them appeared brighter than usual; the whiteness of the milky way was like a pure flame which shot across the heavens; and with the naked eye they could observe clusters of stars that were invisible from below. Had Jupiter been visible, he is of opinion that some of his satellites might have been discovered with the naked eye, or at least with a very small pocket-glass. He likewise took notice of several of those meteors called falling stars, which ap¬ peared as much elevated as when viewed from the plain; a proof, according to Mr Brydone, that “ these bodies move in regions much beyond the bounds that some phi¬ losophers have assigned to our atmosphere.” To have a full and clear prospect from the summit of Mount iEtna, it is necessary to be there before sunrise, as the vapours raised by the sun in the daytime will ob¬ scure every object. Accordingly, our travellers took care to arrive there early enough; and all agree, that the beauty of the prospect from thence cannot be described. Here Mr Brydone and Sir William Hamilton had a view of Calabria in Italy, with the sea beyond it; the Lipari islands, and Stromboli, a volcano at about 70 miles dis¬ tance, appeared just under their feet: the whole island of Sicily, with its rivers, towns, harbours, &c. appeared distinct, as if seen on a map. Massa, a Sicilian author, affirms, that the African coast, as well as that of Naples, with many of its islands, has been discovered from the top of ./Etna. The visible horizon here is no less than 800 or 900 miles in diameter. The pyramidal shadow of the mountain reaches across the whole island, and far into the sea on the other side, forming a visible track in the air, which, as the sun rises above the horizon, is shortened, and at last confined to the neighbourhood of ./Etna. The most beautiful part of the scene, however, in Mr Bry- done’s opinion, is the mountain itself, the island of Sicily, and the numerous islands lying round it. These last seem to be close to the skirts of ./Etna, the distances appearing reduced to nothing. M. Houel gives the following description of the view he enjoyed from the summit of the mountain. Here, being sheltered from the wind, and the day advancing, they began to enjoy the glorious prospect, which every moment became more extensive. At the rising of the sun, the horizon was serene, without a single cloud. “ The coast of Calabria,” says our author, “‘was as yet undis- tinguishable from the adjoining sea ; but in a short time a fiery radiance began to appear from behind the Italian hills which bounded the eastern part of the prospect. iE T N A. The fleecy clouds, which generally appear early in the kvK morning, were tinged with purple ; the atmosphere became r str0ngly illuminated, and, reflecting the rays of the rising sun, appeared filled with a bright effulgence of flame. The immense elevation of the summit of ./Etna made it catch the first rays of the sun’s light, whose vast splendour, while it dazzled the eyes, diffused a most cherishing and enliven¬ ing heat, reviving the spirits, and diffusing a pleasant sen¬ sation throughout the soul. But though the heavens were thus enlightened, the sea still retained its dark azure, and the fields and forests did not yet reflect the rays of the sun. The gradual rising of this luminary, however, soon diffused his light over the hills which lie below the peak of iEtna. This last stood like an island in the midst of the ocean, with luminous points every moment multiplying around, and spreading over a wider extent with the greatest rapidity. It was as if the universe had been observed suddenly springing from the night of non-existence. The tall forests, the lofty hills, and extensive plains of iEtna, now presented themselves to view. Its base, the vast tracts of level ground which lie adjacent, the cities of Si¬ cily, its parched shores, with the dashing waves and vast expanse of the ocean, gradually presented themselves; while some fleeting vapours, which moved swiftly before the wind, sometimes veiled part of this vast and magnifi¬ cent prospect.” In a short time every thing was display¬ ed so distinctly that they could plainly recognise all those places with which they were before acquainted. On the south were seen the hills of Camerata and Trapani; on the north, the mounts Pelegrino and Thermini, with the cele¬ brated Enna once crowned with the temples of Ceres and Proserpine. Among these mountains were seen a great many rivers running down, and appearing like as many lines of glittering silver winding through a variety of rich and fertile fields, washing the walls of 28 cities, while their banks were otherwise filled with villages, hamlets, &c. ris¬ ing among the ruins of the most illustrious republics of antiquity. On the south and north were observed the rivers which bound by their course the vast base of Mount iEtna, and afford a delightful prospect to the eye ; while at a much greater distance were seen the isles of Lipari, Alicudi, Felicocide, Parinacia, and Stromboli. pgi<|l This mountain is divided into three parts or zones, which are distinguished by the names of the Regions Culta, the fertile or cultivated region ; the Regions Syl- vosa, the woody or temperate region ; and the Regions Deserta, the frigid or desert zone or region. All these are plainly distinguished from the summit. The desert region is a dreary waste of black lava, scoria, and ashes, in the centre of which, in a desolate plain, rises the cone, to the height of eleven hundred feet. Imme¬ diately under the cone is an edifice, erected at the ex¬ pense of the British officers who during the late war were stationed in Sicily, containing rooms and stabling; a great convenience to those travellers who resort to it in the proper season, but during the greater part of the year a single snow storm is sufficient to overwhelm it. Not far from this house are the vestiges of a brick build¬ ing, called the Philosopher s Tower, from the supposition of its having been the dwelling of Empedocles. M. Houel, however, says, “ it seems not to be very ancient, neither the materials of which it consists, nor the mode of archi¬ tecture, bearing any resemblance to those of the Greeks i . or Romans.” tfv| ' . Immediately below the desert region is the woody region, which is an extensive forest of about six or seven miles in length, encircling the mountain, and affording pasturage to the numerous flocks and herds that are fed there. The woods are irregularly distributed, ac- VOL. II. 201 cording to the ravages of the lava, and the senseless de- jEtna. struction of them by the natives. The neighbourhood of Maletto is richly clothed with fine oaks, pines, and poplars ; above Nicolosi and Milo are produced stunted oaks, with fir, beech, cork, hawthorn, and bramble; and in the dis-- tricts of Mascali and Piraino there are groves of cork, and luxuriant chesnut trees. The vicinity of Bronte abounds with pines of great magnitude; but the Carpinetto boasts that father of the forest, the venerable Castagno di cento cavalli, or chesnut of the hundred horses, supposed to be one of the oldest known trees, and, as far as is known, the largest tree in Europe. Some travellers describe it as a single tree ; others, and with more plausibility, as produced by the inosculation of several young chesnut trees. It ap¬ pears to consist of five large and two smaller trees. The largest trunk Captain Smyth found to measure 38 feet in circumference, and the circuit of the whole five, measured just above the ground, is 163 feet. It still bears rich fo¬ liage, and much small fruit, though the heart of the trunk is decayed, and a public road leads through them. Be¬ sides this, there is abundance of other trees in the neigh¬ bourhood, very remarkable for their size. One is men¬ tioned as being upwards of 70 feet in circumference. Many parts of this region are remarkably picturesque, and even romantic; and its cool temperature is extreme¬ ly grateful when contrasted with the heat of the lower region. “ These majestic forests of jEtna,” says Houel, “ afford a singular spectacle, and bear no resemblance to those of other countries. Their verdure is more lively, and the trees of which they consist are of a greater height. These advantages they owe to the soil whereon they grow ; for the soil produced by volcanoes is particularly favourable to vegetation, and every species of plants grows here with great luxuriance. In several places, where we can view their interior parts, the most enchanting prospects are dis¬ played. The hawthorn trees are of an immense size. Our author saw several of them of a regular form, and which he was almost tempted to take for large orange trees cut artificially into the figures they represented. The beeches appear like as many ramified pillars, and the tufted branch¬ es of the oak like close bushes impenetrable to the rays of the sun. The appearance of the woods in general is ex¬ ceedingly picturesque, both by reason of the great number and variety of the trees, and the inequality of the ground, which makes them rise like the seats in an amphitheatre, one row above another; disposing them also in groups and glades, so that their appearance changes to the eye at every step; and this variety is augmented by accidental circumstances, as the situation of young trees among others venerable for their antiquity; the effects of storms, which have often overturned large trees, while stems shooting up from their roots, like the Lernsean hydra, show a number of heads newly sprung to make up that which was cut off.” Several extensive caverns occur in this region, among which, one is well known by the name of the Goats Ca¬ vern or Grotto, because it is frequented by those animals, which take refuge there in bad weather. Formerly tra¬ vellers on their ascent rested here, but since the erection of the more convenient shelter higher up the mountain, called the English House, it has been abandoned. The fertile district or region comprises the delightful Regione country round the skirts of the mountain, and is veryCuita. unequal in its dimensions, being in many parts from six to nine miles broad, and above Catania nearly eleven ; while on the northern side, where the woods encroach, it is little more than half a mile broad. The whole is more or less covered with towns, villages, and monasteries, and 2 c 202 iE T N A. jEtna. is well peopled, notwithstanding the danger of such a situa- tion. The soil is made up of decomposed lava and tuffa. It is easily worked and very productive, yielding the finest corn, oil, wine, fruit, and aromatic shrubs, in Sicily. The inhabitants, however, of many of these districts, as Smyth remarks, from the numerous minute particles of volcanic dust that fly about, severely injuring and disfiguring their eyes, and soiling their persons, their furniture, and their houses, have a squalid, slovenly, and dejected appearance. These circumstances, with the want of water, and the nu¬ merous and arid patches of lava amidst the surrounding vegetation, leave such a paradise little to be envied. In addition to these inconveniences, the constant danger of losing both landed and movable property by an erup¬ tion must be borne in mind; a disaster compared with which, earthquakes, hurricanes, plagues, and other visita¬ tions are light, as these may be counteracted in a few years, while the other destroys for ages. The terrible erup¬ tion of 1699 burst forth in this region. In this region the river Acts, so much celebrated by the poets, in the fable of Acis and Galatea, takes its rise. It bursts out of the earth at once in a large stream, runs with great rapidity, and about a mile from the source throws itself into the sea. Season for The most desirable season, according to Smyth, for as- ascending cending the mountain, is during the full moons that occur taf m°Un* between the middle of June and the first autumnal 1’ains. The latter appear in the form of snow on the summit; and the peasants below attentively observe whether the east or west side is covered earliest, because in the former case they expect a wet season, and in the latter a dry one. After the equinox the weather again becomes settled, and the journey is practicable and easy until the middle of October. The ascent from Catania, through Nicolosi, to the English house, is effected on mules with the greatest ease, or even in a Lettiga ; but from thence to the top of the . cone the journey is very fatiguing. The obstacles are nu¬ merous : the surface, towards the summit, is frequently so hot as to make even resting inconvenient, and the materials, being only scoria, puzzolana, and triturated ashes, occasion the foot to sink and recede more or less at every step. Geognosti- This mighty mountain, which rises suddenly from the cal struc- surrounding low country, is mostly composed of porphyri- ture‘ tic lavas, which in every instance possess such characters as show that in all probability they have been ejected above the surface of the waters, and not under pressure. It rises out of a basaltic crater of elevation, hence its lower part is of a basaltic nature. The products of the eruptions of this mountain, in point of magnitude, form a striking con¬ trast with those of Vesuvius; for even the greatest bodies of lava erupted from the Neapolitan mountain almost sink into insignificance when compared with those of TEtna some of the streams or coulees of iEtna being four or five miles in breadth, 15 in length, and from 50 to 100 feet in thickness. The elevation of iEtna, too, is so great that the lava fre¬ quently finds less resistance in piercing the flanks of the mountain than in rising to its summit; and has in this man¬ ner formed a number of minor cones, many of which pos¬ sess their respective craters, and have given rise to con¬ siderable streams of lava. The most striking and original feature in the physiognomy of iEtna, says Dr Daubeny, is the zone of subordinate volcanic hills with which it is encompassed, and which look like a court of subaltern princes waiting upon their sovereign. Of these, some are covered with vegetation, others are bare and arid, their relative antiquity being probably denoted by the progress vegetation has made upon their surface; and the great difference which exists in this respect seems to indicate, that the mountain, to which they owe their origin, must have been in a state of activity, if not at a period ante¬ cedent to the commencement of the present order of things, at least at a distance of time exceedingly remote. It must be remarked, however, continues Daubeny, that the time which it takes to bring a volcanic mountain or stream of lava into cultivation is very variable ;l and that the progress is generally more rapid in a cone composed of finely comminuted cinders, than in a stream of lava, which consists of a hard glossy substance, that yields but slowly to the causes of decomposition. There is nothing in the nature of lava, chemically considered, prejudicial to vege¬ tation ; but mechanically, the hard surface is inimical, as it gives no support to the tender shoots, and from its vesicularity often carries off all the moisture that falls on its surface. From these causes, the surface of a stream of lava must always require a long time to bring it into cul¬ tivation. This being the case, we naturally feel desirous of verifying an observation reported by Brydone, on the authority of the canon Recupero, which might render us doubtful as to the correctness of our received chronologies. This writer, says Dr Daubeny, after giving an instance of a lava, the date of which goes back to the time of the second Punic war, proceeds to state, that at Aci Reale we see seven such beds superimposed one on the other, each of which has its surface thoroughly decomposed and con¬ verted into rich vegetable mould. Now, if a single bed of lava has continued for more than 2000 years without ex¬ periencing any alteration, what a lapse of time must it have required to reduce seven successive beds of the same material into a state of such decomposition. “ Although I have no reason,” says Dr Daubeny, “ to doubt that Brydone received from Recupero the observa- 1 “ This will appear from the following statement of the condition of a few of the lavas of Vesuvius, which I examined with reference to this question in 1823 : Lava of 1551—Fossa di Gaetano. Much decomposed; heaths grow upon it, and vines begin to be planted. 1737—But little decomposed; moss alone grows on it. 1760.—Near the hill of the Camalduli. Still unfit for vegetation ; surface, however, whitened and crumbly, owing to decomposition, which has proceeded farther than in that of 1737. 1771.—Colour grey; moss grows upon it, but no heath. 1785—Fossa di Sventurato. Lava still quite hard and rough. 1794.—I ossa di Cucazzello. Surface much decomposed ; moss grows upon it, and a few heaths, but no trees or shrubs. It is to be observed, that even the latter are met with on the surface of the crater from which this lava flowed, and which was formed by heaps of scoriae ejected at the same time ; a proof of what I have asserted in the text with respect to the more rapid decomposition ofloose ashes than of a bed of lava. 1805—Fossa del Noce. Colour very white ; no moss appears to grow upon it; but, being covered with the loose scoria- of later eruptions, it has trees growing upon it in a few' parts. 1810—Colour grey ; surface rough, though somewhat decomposed ; moss grows upon it, but no heaths or trees are seen, except in one part where it is covered with cinders. • 1822—Colour black; surface very rough and irregular; no moss as yet to be seen. It will be seen that many of these lavas are in a more forward state than that of Ischia, which flowed in 1302, more than 200 years before.” (Daubeny's Volcanoes, p. 204.) iE T N A. 203 tion on which he grounds his inferences, I think it most L/'-fw-'probable that the conclusion itself was his own, though he perhaps thought it would sound more piquant if put into the mouth of the Canon, whose scientific knowledge he seems willing to exalt at the expense of his orthodoxy. In reality, however, this good priest appears to have, en¬ joyed in both respects a reputation which he very little deserved. The reports of Dolomieu and other really scien¬ tific travellers make him out to have been a man of but slender philosophical attainments, but as one who at least was free from all imputation of scepticism. It is curious, nevertheless, that another foreigner has stated, as an in¬ stance of the intolerant spirit prevailing in the country in which he lived, that the poor Abbe was thrown into pri¬ son for his religious opinions, although the truth appears to have been, that the reports circulated in his favour by Brydone, Borch, and others, induced the Neapolitan go¬ vernment to grant him a pension on the score of his scien¬ tific deserts. Indeed, the only annoyance, it is said, he ever experienced in consequence of his imagined disco¬ very, was the being informed that certain foreigners, to whom he communicated his observation, not content with wresting it to a purpose of which he had never dreamt, had given him credit for the inferences which th'y had chosen to deduce from it themselves. “ The fact, nevertheless, reported by Brydone, obtain¬ ed a currency proportionate to the popularity which his work enjoyed; and the heterodox conclusion excited at the time no slight degree of consternation among divines. It was generally combated, by remarking the great vari¬ ableness as to the period which a bed of lava will take to undergo decomposition ; and even Spallanzani, though he visited Sicily, seems to have contented himself with point- ingout instances in which newer beds of lava have taken the start of older ones in their progress towards cultivation. “ I was therefore not a little surprised, when, on visit¬ ing the celebrated spot of the Abbe’s observation, I found that the beds of vegetable mould, which proved, accord¬ ing to Brydone, the degree to which the decomposition of the lava had extended, were in reality nothing more nor less than beds of a ferruginous tuffa, formed probably at the very period of the flowing of the lava, and originating perhaps from a shower of ashes that immediately succeed¬ ed its eruption. It is true that the cliff, which exhibits a section of these lava beds with interposed tuffa, shows also the greater facility with which the latter has yielded to the action of the elements, as the bare and mural preci¬ pices presented by the lava are in contrast with the gentler slope of the beds of tuffa, which afford a soil sufficient for the hardy cactus, and in some places even for the vine. Still there is not the slightest evidence that the decom¬ position exists internally, or that it had taken place in any one instance before the superincumbent bed of lava was deposited. “ Even had the tuffa in question been in xedSXy vegetable mould, the validity of Mr Brydone’s conclusion might very easily be disputed, for I think it cannot be shown that any one of the beds, of which the cliff of Aci Reale exposes a section, are of postdiluvial origin. So abrupt and lofty a face of rock would hardly have been cut by processes now in operation, but may be attributed with more probability to the cause which last reduced our con¬ tinents to their existing form. “ If we examine, too, the characters of these beds, we shall find them sufficiently distinguished by their greater compactness and stony aspect from modern lavas; whilst the general correspondence in mineralogical characters that exists between them all, affords a strong presumption of their having been produced about the same period. “ But it is useless to multiply proofs of the fallacy of ^tna. Mr Brydone’s statement; and the only circumstance that^^v^- needs surprise us is, that thirty years should have elapsed without any traveller having visited the spot with the view of ascertaining the correctness of the observation. “ Should the high antiquity I have assigned to this volcano be questioned, I may remark, that there are valleys on the slope of the mountain which appeared to me too considerable to be the result of torrents, and that among * the diluvial matter at its foot, I have found rolled masses of cellular as well as compact lava; the presence of the former seeming to prove that the volcano was in activity at some period intermediate between the general retreat of the ocean and the event which formed the valleys, and reduced the fragments of rock detached to the rounded condition in which we observe them.” (Daubeny’s Volca¬ noes, p. 206.) We shall close this article with an enumeration of all the different eruptions from Mount /Etna which are found upon record. 1. The first is that of which Diodorus Siculus speaks, List of but without fixing the period at which it happened. That eruptions, eruption, says he, obliged the Sicani, who then inhabited Sicily, to forsake the eastern and retire to the southern part of the island. A long time after that, the Sicilians, a people of Italy, migrated into Sicily, and took up their abode in that part of the island which had been left desert by the Sicani. 2. The second eruption known to have issued from this volcano is the first of the three mentioned by Thucydides; of none of which he fixes the date, mentioning only in general, that from the arrival of the first Greek colonies that settled in Sicily (which was in the 11th Olympiad, and corresponds to the 734th year before the Christian era), to the 88th Olympiad, or the year 425 before Christ, iEtna at three different times discharged torrents of fire. This second eruption happened, according to Eusebius, in the days of Phalaris, in the 565th year before the Chris¬ tian era. The assertion of Eusebius is confirmed by a letter from that tyrant to the citizens of Catania, and by the answer of the Catanians (if, after Bentley’s Dissertations against their authenticity, any credit be due to the Epistles of Phalaris). But Diodorus gives both these pieces. 3. The third, which is the second of the three mention¬ ed by Thucydides, happened in the 65th Olympiad, in the 477th year before the Christian era, when Xantippus was archon at Athens. It was in this year that the Athenians gained their boasted victory over Xerxes’s general Mar- donius near Plataea. Both the eruption of the volcano and the victory of the Athenians are commemorated in an ancient inscription on a marble table, which still remains. An ancient medal exhibits a representation of an astonishing deed to which that eruption gave oc¬ casion. Two heroic youths boldly ventured into the midst of the flames to save their parents : their names, which well deserve to be transmitted to future ages, were Amphi- nomus and Anapius. The citizens of Catania rewarded so noble a deed with a temple and divine honours. Seneca, Silius Italicus, Valerius Maximus, and other ancient authors, mention the heroism of the youths with just applause. 4. The fourth eruption, the third and last of those mentioned by Thucydides, broke out in the 88th Olympiad, in the 425th year before the Christian era. It laid waste the territory of Catania. 5. The fifth is mentioned by Julius Obsequens and Oro- sius, who date it in the consulship of Sergius Fulvius Flaccus and Quintus Calpurnius Piso, nearly 133 years before the Christian era. It was considerable; but no peculiar facts are related concerning it. JE T 6. In the consulship of Lucius iEmilius Lepidus and Lucius Aurelius Orestes, in the 125th year before the Christian era, Sicily suffered by a violent earthquake. Such a deluge of fire streamed from iEtna as to render the adjoining sea, into which it poured, absolutely hot. Orosius says, that a prodigious quantity of fishes were destroyed by it. Julius Obsequens relates, that the inhabitants of the Isles of Lipari ate such a number of those fishes as to suffer, in consequence of it, by a distemper which proved very generally mortal. 7. Four years after the last mentioned, the city of Ca¬ tania was desolated by another eruption, not less violent. Orosius relates, that the roofs of the houses were broken down by the burning ashes which fell upon them. It was so dreadfully ravaged, that the Romans found it necessary to grant the inhabitants an exemption from all taxes for the space of ten years, to enable them to repair it. 8. A short time before the death of Caesar, in the 43d 3^ear before Jesus Christ, there was an eruption from Mount ./Etna. Livy mentions it. Rhegium suffered dur¬ ing this eruption. It was afterwards considered as an omen of the death of Caesar. 9. Suetonius, in the life of Caligula, mentions an erup¬ tion from Mount /Etna which happened in the 40th year after the Christian era. The emperor fled on the very night on which it happened, from Messina, where he at that time happened to be. 10. Carrera relates, that in the year 253 there was an eruption from Mount .Etna. 11. He speaks of another in the year 420, which is also mentioned by Photius. 12. In the reign of Charlemagne, in the year 812, there was an eruption from Etna. Charlemagne, who witness¬ ed it, was much alarmed. 13. In the year 1169, on the 4th February, about day¬ break, there was an earthquake in Sicily, which was felt as far as Reggio, on the opposite side of the strait. Ca¬ tania was reduced by it to ruins; and in that city more than 15,000 souls perished. The bishop, with 44 monks of the order of St Benedict, was buried under the ruins of the roof of the church of St Agatha. Many castles in the territories of Catania and Syracuse were overturned; new rivers burst forth, and ancient rivers disappeared. The ridge of the mountain was observed to sink in on the side next Taormino. The spring of Arethusa, so famous for the purity and sweetness of its waters, then became muddy and brackish. The fountain of Ajo, which rises from the village of Saraceni, ceased to flow for two hours, at the end of which the water gushed out more copiously than before. Its waters assumed a blood colour, and re¬ tained it for about an hour. At Messina, the sea, without any considerable agitation, retired a good way beyond its ordinary limits; but soon after returning, it rose beyond them, advanced to the walls of the city, and entered the streets through the gates. A number of people who had fled to the shore for safety were swallowed up by the waves. Ludovico Aurelio relates, that the vines, corn, and trees of all sorts were burnt up, and the fields cover¬ ed over with such a quantity of stones as rendered them unfit for cultivation. At this time a great part of Syria was wasted by an earthquake. 14. Twelve years after this, in the year 1181, a dread¬ ful eruption issued from Etna, on the east side. Streams of fire ran down the declivity of the mountain, and en¬ circled the church of St Stephen, but without burning it. Nicholas Speciale, who relates, though he did not see, this event, was witness to another conflagration on Etna 48 years after this, in the year 1329, on the 23d of June, of which he has given a description. N A. 15. On that day, says he, about the hour of vespers Etna was strongly convulsed, and uttered dreadful noises: not only the inhabitants of the mountain, but all Sicily, were struck with consternation and alarm. On a sudden' a terrible blaze of fire issued from the southern summit and spread over the rocks of Mazzara, which are always covered with snow. Together with the fire, there appear¬ ed a great deal of smoke. After sunset, the flames, and the stones that issued out with them, were seen to touch the clouds. The fire making way for itself with the most furious impetuosity, burnt up or reduced to ruins all those structures which the piety of former times had consecrat¬ ed to the Deity. The earth yawning, swallowed up a great many springs and rivulets. Many of the rocks on the shore of Mascali were shaken and dashed into the sea. A succession of these calamities continued till the 15th of July, when the bowels of Etna were again heard to rebellow. The conflagration of Mazzara still went on unextinguished. The earth opened near the church of St John, called II Paparmecca ; on the south side fire issued from the gap with great violence. To add to the horrors of the day, the sun was obscured from morning to evening with clouds of smoke and ashes, as entirely as in an eclipse. Nicholas Speciale went towards the new opened crater, to observe the fire and the burning stones which were issuing from the volcano. The earth rebel¬ lowed and tottered under his feet; and he saw red-hot stones issue four times successively in a very short space from the crater with a thundering noise, the like of which, he says, he had never before heard. In a few days after this, all the adjacent fields were burnt up by a shower of fire and sulphurous ashes; and both birds and quadrupeds, being thus left destitute of food, died in great numbers. A great quantity of fishes likewise died in the rivers and the contiguous parts of the sea. “ I cannot think,” says he, “ that either Babylon or Sodom was destroyed with such awful severity.”—The north winds, which blew at the time, carried the ashes as far as Malta. Many persons of both sexes died of terror. 16. Scarcely had four years elapsed after this terrible event, when Etna made a new explosion, and discharged volleys of stones, causing the neighbouring fields to trem¬ ble. This happened in the year 1333. 17. Forty-eight years after this, on the 25th of August 1381, an eruption from Etna spread its ravages over the confines of the territory of Catania, and burnt up the olive yards in the neighbourhood of that city. 18. In the year 1444, 63 years after the last eruption, a torrent of lava issued from Etna, and ran towards Ca¬ tania. The mountain shook; and the shocks were so violent, that several huge masses of rock were broken from its summit, and hurled into the abyss with a tremen¬ dous noise. 19. After this Etna was scarcely at rest for 18 months or two years. On Sunday the 25th of September 1446, about an hour after sunset, an eruption issued from the place called La Pietra di Mazzara. This eruption was soon over. 20. In the following year, 1447, on the 21st of Septem¬ ber, there was another, with a good deal of fire; but this eruption was likewise of short duration. 21. Etna now ceased to emit fire, and that for a con¬ siderable time. The neighbouring inhabitants not only ascended to the summit of the mountain, but even, if we may credit accounts, went down into the fiery gulf, and believed the volcanic matter to be now exhausted. But on the 25th of April 1536, near a century from the slight eruption in 1447, a strong wind arose from the west, and a thick cloud, reddish in the middle, appeared over the .ETNA. 205 summit of the mountain. At the very same instant a Vx -'L'large body of fire issued from the abyss, and fell, with the noise and rapidity of a torrent, along the eastern side of the mountain, breaking down the rocks, and destroying the flocks and every other animal that was exposed to its fury. From the same crater, on the summit of the moun¬ tain, there issued at the same time a stream of fire more terrible than the other, and held its course towards the west. It ran over Bronte, Adrans, and Castelli. It con¬ sisted entirely of sulphur and bitumen. On the same day the church of St Leon, which stood in a wood, was first demolished by the shocks of the earthquake, and its ruins after that were consumed by the fire. Many chasms were opened in the sides of the mountain; and from these issued fire and burning stones, which darted up into the air with a noise like that produced by a smart discharge of artillery. Francis Negro de Piazza, a celebrated phy¬ sician, who lived at Lentini, wishing to have a nearer view of the eruptions, and to make some observations which he thought might be of consequence, was carried off and burnt to ashes by a volley of the burning stones. This conflagration of .Etna lasted some weeks. 22. In less than a year, on the 17th of April 1537, the river Simeto swelled so amazingly as to overflow the ad¬ jacent plains, and carry off the country people, and their cattle and other animals. At the same time, the country around Paterno, the neighbouring castles, and more than 500 houses, were destroyed by the ravages of the river ; and most of the wood was torn up by the roots by violent blasts of wind. These ravages of the elements were fol¬ lowed by .Etna, which on the 11th of the following month was rent in several places, disclosing fiery gulfs, and pour¬ ing out a deluge of fire in more terrible torrents than those of the preceding year. They directed their course to¬ wards the monastery of St Nicholas d’Arena ; destroyed the gardens and vineyards ; and proceeding onwards to¬ wards Nicolosi, burnt Montpellieri and Fallica, and de¬ stroyed the vineyards and most of the inhabitants. When the conflagration ceased, the summit of the mountain sunk inward with such a noise, that all the people in the island believed the last day arrived, and prepared for their end by extreme unction. These dreadful disturbances con¬ tinued throughout the whole year, more especially in the months of July and August, during which all Sicily was in mourning. The smoke, the noise, and the shocks of the earthquake, affected the whole island ; and if Filotes may be believed, who relates this event, many of the Sicilians were struck deaf by the noise. Many structures were demolished; and among others the castle of Cor- leone, though more than 25 leagues distant from the volcano. 23. During the succeeding 30 years there was no dis¬ turbance of this nature. At the end of that space, Sicily was alarmed by a new eruption from the mountain. Etna discharged new streams of fire, and covered the adjacent country with volcanic ashes, which entirely ruined the hopes of the husbandman. 2L In the year 1579 Etna renewed its ravages; but [ no particular account of the damage which it did upon this occasion has been transmitted to us. 25. Twenty-five years had elapsed, when Etna, in the month of June 1603, flamed with new fury. Peter Car¬ rera affirms that it continued to emit flames for the space ot 33 years, till 1636, without interruption, but not always with the same violence. In 1607 the streams of lava which flowed from it destroyed the woods and vineyards on the west side of the mountain. In 1609 they turned their course towards Aderno, and destroyed a part of the forest Del Pino, and a part of the wood called La Sciam- brita, with many vineyards in the district Costerna. These Etna, torrents of lava continued to flow for three months. the year 1614 a new effort of the subterraneous fire open¬ ed another crater, from which fire was discharged on Randazzo, in the district called U Piro. The fire continued to flame for 10 or 12 years longer. 26. The same Peter Carrera relates, that a dreadful conflagration happened in the year 1664, of which he himself was witness. It happened on the 13th of Decem¬ ber, and lasted without interruption, but with different degrees of violence, till the end of May 1678. But in 1669 the inhabitants of Nicolosi were obliged to forsake their houses, which tumbled down soon after they left them. The crater on the summit of Etna had not at this time a threatening aspect, and every thing there con¬ tinued quiet till the 25th of March : but on the 8th of that month, an hour before night, the air was observed to become dark over the village La Pedara and all that neigh¬ bourhood ; and the inhabitants of that country thought that an almost total eclipse was taking place. Soon after sunset, frequent shocks of earthquakes began to be felt: these were at first weak, but continued till day-break to become more and more terrible. Nicolosi was more af¬ fected than any other tract of country on that side of Etna. About noon every house was thrown to the ground; and the inhabitants fled in consternation, invoking the protec¬ tion of heaven. On the 10th of March a chasm several miles in length, and five or six feet wide, opened in the side of the mountain ; from which, about two hours before day, there arose a bright light, and a very strong sulphur¬ ous exhalation was diffused through the atmosphere. About 11 in the forenoon of the same day, after dread¬ ful shocks of earthquake, a crater was opened in the hill called Des Noisettes, from which there issued huge volumes of smoke, not accompanied with fire, ashes, or stones, but with loud and frequent claps of thunder, displaying all the different phenomena with which thunder is at different times attended. And what was very remarkable, the chasm was formed on the south side, between the top and the bottom of the mountain. On the same day another chasm, was formed two miles lower, from which issued a great deal of smoke, accompanied with a dreadful noise and earthquake. Towards the evening of the same day, four other chasms were opened towards the south, in the same direction, accompanied during their formation with the same phenomena, and extending all the way to the hill called La Pusara. About twelve paces beyond that, another of the same kind was formed. On the succeeding night, a black smoke, involving a quantity of stones, issued from this last chasm: it discharged at the same time flakes of a dark-coloured spongy matter, which became hard after they fell. There issued from the same gulf a stream of lava, which held its course into a lake called La Hardia, six miles from Mont¬ pellieri, and on its way thither destroyed many dwelling- houses and other buildings in the neighbouring villages. On the next day, March 12th, this stream of fire di¬ rected its course towards the tract of country called Mal- passo, which is inhabited by 800 people: in the space of 20 hours it was entirely depopulated and laid waste. The lava then took a new direction, in which it destroyed some other villages. The mount of Montpellieri was next destroyed, with all the inhabitants upon it. On the 23d of the same month, the stream of fire was in some places two miles broad. It now attacked the large village of Mazzalucia; and on the same day a vast gulf was formed, from which were discharged sand or ashes, which produced a hill with two summits, two miles iE T N A. in circumference, and 150 paces high. It wag observed 'to consist of yellow, white, black, grey, red, and green stones. The new mount of Nicolosi continued to emit ashes for the space of three months ; and the quantity discharged was so great as to cover all the adjoining tract of country for the space of 15 miles. Some of these ashes were con¬ veyed by the winds as far as Messina and Calabria ; and' a north wind arising, covered all the southern country about Agosta, Lentini, and even beyond that, in the same manner. While at that height on Nicolosi so many extraordinary appearances were passing, the highest crater on the sum¬ mit of iEtna still preserved its usual tranquillity. On the 25th of March, about one in the morning, the whole mountain, even to the most elevated peak, wras agi¬ tated by a most violent earthquake. The highest crater of iEtna, which was one of the loftiest parts of the moun¬ tain, then sunk into the volcanic focus ; and in the place which it had occupied, there now appeared nothing but a wide gulf more than a mile in extent, from which there issued enormous masses of smoke, ashes, and stones. At that period, according to the historian of this event, the famous block of lava on Mount Frumento was discharged from the volcanic focus. In a short time after, the torrent of fire, which still continued to flow, directed its course towards Catania with redoubled noise, and accompanied with a much greater quantity of ashes and burning stones than before. For several months many most alarming shocks of earthquakes were felt, and the city was threatened with destruction by the torrent of fire. In vain they attempted to turn or divert its course: the lava rose over the walls, and enter¬ ed by an angle near the Benedictine convent on the 11th of June following. This awful events related by Francis Monaco, Charles Mancius, Vincent Auria, and Thomas Thedeschi. A description of the lava issuing from Mount Aiitna in 1669 was sent to the court of England by Lord Winchel- sea, who at that time happened to be at Catania on his way home from an embassy to Constantinople. Sir W. Hamilton gives the following extract from it. “ When it was night, I went upon two towers in divers places ; and I could plainly see, at ten miles distance, as we judged, the fire begin to run from the mountain in a direct line, the flame to ascend as high and as big as one of the great¬ est steeples in your Majesty’s kingdoms, and to throw up great stones into the air. I could discern the river of fire to descend the mountain, of a terrible fiery or red colour, and stones of a paler red to swim thereon, and to be some as big as an ordinary table. We could see this fire to move in several other places, and all the country covered with fire, ascending with great flames in many places, smoking like a violent furnace of iron melted, making a noise with the great pieces that fell, especially those that fell into the sea. A cavalier of Malta, who lives there, and attended me, told me, that the river was as liquid, where it issues out of the mountain, as water, and comes out like a tor¬ rent with great violence, and is five or six fathom deep, and as broad, and that no stones sink therein.” The account given in the Philosophical Transactions is to the same purpose. W’e are there told, that the lava is “ nothing else than divers kinds of metals and minerals, ren¬ dered liquid by the fierceness of the fire in the bowels of the earth, boiling up and gushing forth as the water doth at the head of some great river; and having run in a full body for a stone’s cast or more, began to crust or curdle, becoming, when cold, those hard porous stones which the people call sciarri. These, though cold in comparison of what first issues from the mountain, yet retained so much heat as to resemble huge cakes of sea-coal strongly ignited,1^ \j and came tumbling over one another, bearing down or burning whatever was in their way. In this manner the lava proceeded slowly on till it came to the sea, when a most extraordinary conflict ensued betwixt the two ad¬ verse elements. The noise ivas vastly more dreadful than the loudest thunder, being heard through the whole coun¬ try to an immense distance ; the water seemed to retire and diminish before the lava, while clouds of vapour dark¬ ened the sun. The whole fish on the coast were destroyed, the colour of the sea itself was changed, and the trans¬ parency of its waters lost for many months.” While this lava was issuing in such prodigious quantity, the merchants, whose account is recorded in the Philoso¬ phical Transactions, attempted to go up to the mouth it¬ self, but durst not come nearer than a furlong, lest they should have been overwhelmed by a vast pillar of ashes, which to their apprehension exceeded twice the bigness of St Paul’s steeple in London, and went up into the air to a far greater height. At the mouth itself was a continual noise, like the beating of great waves of the sea against rocks, or like distant thunder, which was sometimes so violent as to be heard 60, or even 100 miles off; to which distance also part of the ashes was carried. Some time after, having gone up, they found the mouth from whence this terrible deluge issued to be only a hole about 10 feet diameter. This is also confirmed by Mr Brydone; and is probably the same through which Sir William Hamilton de¬ scended into the subterranean caverns already mentioned. 27. Some years after this conflagration, a new burning gulf opened, in the month of December 1682, on the sum¬ mit of the mountain, and spread its lava over the hill of Mazzara. 28. On the 24th of May 1686, about ten in the even¬ ing, a new eruption burst out from the summit of the mountain, on the side contiguous to the hill Del Bue. Such a quantity of inflamed matter was thrown out as consum¬ ed woods, vineyards, and crops of grain, for four leagues round. It stopped its course in a large valley near the castle of Mascali. Several people from the neighbourhood had ascended a hill between the wood of Catania and the confines of Cirrita, to observe the progress of the lava; but the hill on a sudden sunk inwards, and they were buried alive. 29. iLtna was now long quiet; for no less a space of time indeed than one half of the present age. In the year 1755 its eruptions were renewed. During these eruptions, there issued from the mountain a great torrent of boiling- hot salt water. This water took its course down the west side of theErJo# mountain; and the channel which it cut for itself is still of j1 visible. The eruption of water from burning mountains is h' still much less frequent than that of lava or half-vitrified solid matters, ashes, &c. though that of water, and even mixed with the shells of marine animals (though we are not told whether it was salt or not), has sometimes been observed in other volcanoes, particularly Vesuvius. The eruption we now speak of happened in the month of Fe¬ bruary 1755. It was preceded by an exceedingly thick black smoke issuing from the crater, intermixed with flashes of fire. This smoke gradually became thicker, and the bursts of flame more frequent. Earthquakes and sub¬ terraneous thunder convulsed the mountain, and struck the inhabitants of the adjacent parts with the utmost terror. On Sunday the 2d of March, the mountain was seen to emit a huge column of smoke, exceedingly dense and black, with a dreadful noise in the bowels of the earth, accompanied also with violent flashes of lightning. From iE T N A. 207 time to time there were loud cracks, like the explo- v'L/gions of cannon; the mountain appeared to shake from its ' foundations; the air on that side next Mascali became very dark, and loud peals of thunder were heard. These seemed to issue from two caverns, considerably below the summit, on the side of the mountain, and were accom¬ panied with violent blasts of wind like a tempest. 1 These terrible phenomena continued and increased. jEtna seemed ready to swallow up at once all those ma¬ terials which it had been for so many years disgorging, or rather about to sink at once into the bowels of the earth, from whence it appeared to have been elevated. The prospect was far beyond any idea that can be given by description of this tremendous scene. The inhabitants were alarmed beyond measure; the sight of the flames driven by the winds against the sides of the mountain, the shocks of the earthquake, and the fall of rocks, struck the imagination with a horror not to be conceived. During this dreadful commotion, an immense torrent of water was emitted from the highest crater of the mountain. The whole summit of iEtna was at that time covered with a thick coating of snow. Through this the boiling water directed its course eastward, and in its passage met with frightful precipices. Over these it dashed with the ut¬ most violence, adding its tremendous roaring to the com¬ plicated horrors of this awful scene. The snow, melting instantaneously as the boiling torrent advanced, increased its destructive power by augmenting its quantity; while the mischievous effects of the heat were scarcely diminished, by reason of the immense quantity of boiling liquid which continued to pour from the summit of the mountain. This boiling torrent having dashed its awful cataracts from one chain of rocks to another, at length reached the cultivated plains, which it overflowed for a number of miles. Here it divided itself into several branches, form¬ ing as many deep and rapid rivers, which, after several other subdivisions, discharged themselves into the sea. Though the mountain continued to discharge water in this manner only for half an hour, the ravages of it were very terrible. Not only those of common inundations, such as tearing up trees, hurrying along rocks and large stones, took place here, but the still more dreadful effects of boiling water were felt. Every cultivated spot was laid waste, and every thing touched by it was destroyed. Even those who were placed beyond the reach of the torrent, beheld with inexpressible horror the destruction occasion¬ ed by it; and though the alarming noises which had so long issued from the mountain now ceased in a great measure, the shocks of earthquakes, and the violent smoke which continued to issue from the mountain, showed that the danger was not over. Two new openings were now observed, and two torrents of lava began to make their way through the snow. On the 7th of March a dreadful noise was again heard in the bowels of the mountain, and a new column of very thick and black smoke began to issue from it. A horrid explosion of small stones succeeded, some of which were carried as far as the hills of Mascali, and great quantities of black sand to Messina, and even quite over the strait to Reggio in Calabria. On the shifting of the wind to the northward this sand reached as far as the plains of Agosta. iwo days after, the mountain opened again, and a new torrent of lava was discharged ; which, however, advanced very slowly towards the plain, moving only at the rate of a mile in a day. ' It continued to flow in this manner for six days, when every thing appeared so quiet that the canon Recupero set out to view the changes which had taken place. That gentleman’s design was to trace the course of the dreadful torrent of water above mentioned. * This he was J<:;tna. very easily enabled to do by the ravages it had made; and, by following the channel it had cut all the way from bourse of the sea to the summit of the volcano, he found that thisthecurrent immense quantity of water had issued from the very bowels j>aced '°:v of the mountain. After issuing from the crater, and in-1 eLupero* creasing its stream by passing through and melting the snow which lay immediately below the summit, it destroy¬ ed in an instant a fine and extensive forest of fir-trees. All of these were torn up by the violence of the current, though many were no less than from 24 to 30 inches in diame¬ ter. He observed that the great stream had in its descent divided itself into four branches ; and these had again sub¬ divided themselves into several smaller ones, easily dis¬ tinguishable by the quantity of sand they had deposited. Afterwards re-uniting their streams, they formed many islands, and rivers 900 feet in breadth, and of a depth which could not easily be determined. Proceeding farther down, and still forcing its way among the beds of old lava, the channel of the waters was widened to 1500 feet, until it was again contracted in the valleys as before. Every object which stood in the way of this tremendous torrent was moved from its place. Enormous rocks were not only hurried down, but several of them moved to more elevated situations than those they formerly occupied. Whole hills of lava had been removed and broken to pieces, and their fragments scattered along the course of the river; and the valleys were filled up by vast quantities of sand which the waters had deposited. Our author observed, that even at the time he visited the mountain, about ten years after the eruption, the whole side of it still bore the marks of this deluge. 30. In the year 1763 there was an eruption, which con¬ tinued three months, but with intervals. iEtna was at first heard to rebellow. Flames and clouds of smoke were seen to issue out, sometimes silver-coloured, and at other times, when the rays of the sun fell upon them, of a pur¬ ple radiance. At length they were carried off by the winds, and rained, as they were driven before them, a shower of fire all the way to Catania and beyond it. An eruption soon burst out: the principal torrent divided into two branches, one of which ran towards the east, and fell into a deep and extensive valley. The flames which issued from this new crater afforded a noble spectacle. A pyramid of fire was seen to rise to a prodigious height in the air, like a beautiful artificial fire¬ work, with a constant and formidable battery, which shook the earth under those who were spectators of the scene. Torrents of melted matter, running down the sides of the mountain, diffused a light bright as day through the darkness of night. At sunrising the burning lava was observed to have run round some oaks that were still standing unburnt. Their leaves were all withered. Some birds had fallen from their branches, and been burnt to death. Some people cast wood upon the lava, and it was immediately burnt. This lava continued hot, and exhaled smoke, for two years. For five years after this, no snow appeared on the summit of iEtna. 31. In the year 1764 a new crater was opened at a great distance from Mount iEtna. 32. In the year 1766 another was opened at the grotto of Paterno : fire, smoke, and an inconsiderable torrent of lava, issued out of it. 33. On the 27th of January 1780 a new opening was formed two miles under the last-mentioned crater. On the 28th of February and the 14th of March the earth¬ quake was renewed on the north side, and accompanied with terrible noises. 208 iE T N JE T O vEtna, Between the 6th of April and the 7th of May the con- vulsions were renewed, accompanied with noise as before. A quantity of pumice stones and fine sand was dis¬ charged from it. On the 18th of May the shocks were renewed. On the 23d a new crater was formed on the side of Mount Fru- mento on the summit of iBtna, and from it a torrent of lava discharged, which spread through the valley ofLau- dunza. It was 200 paces in breadth. Two other chinks were opened in the mountain near Paterno, and very near one another. The lava issuing from them proceeded, in the space of seven days, six miles ; on the 25th it had run nine miles. A new crater was likewise opened on the 25th, from which a quantity of red-hot stones continued to issue for half an hour, and fell at a very great distance. There pro¬ ceeded likewise from it a stream of lava, which in the same space of time ran over a tract of country two miles in extent. Several parts of those streams of lava were observed to be cold on the surface, and formed into solid masses, but melted again by a new stream of burning lava, which, however, did not melt the old lava. Account 34. In 1787 there was a great eruption. From the 1st of the to the 10th of July there were signs of its approach. On eruption tpie nth, after a little calm, there was a subterraneous in 1787. no;se) ]ike the sound of a drum in a close place, and it was followed by a copious burst of black smoke. It was then calm till the 15th, when the same prognostics re¬ curred. On the 17th the subterraneous noise was heard again: the smoke was more abundant, slight shocks of an earthquake followed, and the lava flowed from behind one of the two little mountains which form the double head of JEtna. On the 18th, while the spectators were in anxious expectation of a more severe eruption, all was quiet, and continued so for more than 12 hours. Soon after they per¬ ceived some new shocks, accompanied with much noise ; and the mountain threw out a thick smoke, which, as the wind was westerly, soon darkened the eastern horizon. Two hours afterwards a shower of fine black brilliant sand descended : on the east side it was a storm of stones, and at the foot of the mountain a deluge of flashes of fire, of scoria and lava. 4 These appearances continued the whole day. At the setting of the sun the scene changed: a number of conical flames rose from the volcano; one on the north, another on the south, were very conspicuous, and rose and fell alternately. At three in the morning, the mountain appeared cleft, and the summit seemed a burning mass. The cones of light which arose from the crater were of an immense extent, particularly the two just mentioned. The two heads seemed to be cut away; and at their separation was a cone of flame, seemingly composed of many lesser cones. The flame seemed of the height of the mountain placed on the mountain, so that it was probably two miles high, on a base of a mile and a half in diameter. This cone was still covered with a very thick smoke, in which there appeared very brilliant flashes of lightning, a phenomenon which vEtna had not before afforded. At times, sounds like those from the explosion of a large cannon were heard, seemingly at a less distance than the mountain. From the cone, as from a fountain, a jet of many flaming vol- cauic matters was thrown, which were carried to the dis¬ tance of six or seven miles. From the base of the cone a thick smoke arose at the time when the rivers of lava broke out, which for a moment obscured some parts of the flame. This beautiful appearance continued three quarters of an hour. It began the next night with more force, but continued only half an hour. In the intervals, however, iEtna continued to throw out flames, smoke, ig. nited stones, and showers of sand. From the 20th to the 22d, the appearances gradually ceased. The stream of ^ lava was carried towards Bronte and the plain of Lago. ^ After the eruption, the top of the mountain on the western side was found covered with hardened lava, scoria, and stones. The travellers were annoyed by smoke, by showers of sand, mephitic vapours, and excessive heat. They saw that the lava which came from the western point divided into two branches, one of which was direct¬ ed towards Libeccio, the other, as we have already said, towards the plain of Lago. The lava on the western head of the mountain had, from its various shapes, been evidently in a state of fusion ; from one of the spiracula, the odour was strongly that of liver of sulphur. The thermometer, in descending, was at 40 degrees of Fahren¬ heit’s scale; while near the lava, in the plain of Lago, it was 140 degrees. The lava extended two miles; its width was from 13f to 21 feet, and its depth 13J feet. 35. Eruptions in 1792. Eruptions of greater and less magnitude from May until the close of the year. 36.

(0.) iETOLARCHA, in Grecian Antiquity, the principal magistrate or governor of the iEtolians. iETOLIA, a country of ancient Greece, comprehend¬ ing all that tract now called the Despotat, or Little Greece. It was parted on the east by the river Evanus, now the Fidari, from the Locrenses Ozolae ; on the west, from Acarnania, by the Achelous; on the north, it bordered on the country of the Dorians and part of Epirus; and on the south extended to the Bay of Corinth. The iEtolians were a restless and turbulent people, seldom at peace among themselves, and ever at war with their neighbours; utter strangers to all sense of friendship or principles of honour; ready to betray their friends upon the least prospect of reaping any advantage from their treachery: in short, they were looked upon by the other states of Greece no otherwise than as outlaws and public robbers. On the other hand, they were bold and enter¬ prising in war; inured to labour and hardships; undaunt¬ ed in the greatest dangers; jealous defenders of their li¬ berties, for which they were on all occasions willing to venture their lives, and sacrifice all that was most dear to them. They distinguished themselves above all the other nations of Greece in opposing the ambitious designs of the Macedonian princes, who, after having reduced most of the other states, were forced to grant them a peace upon very honourable terms. The constitution of the /Etolian republic was copied from that of the Achaeans, and with a view to form, as it ■were, a counter-alliance; for the jEtolians bore an irreconcilable hatred to the Achaeans, and had conceived no small jealousy at the growing power of that state. The Cleomenic war, and that of the allies, called the social war, were kindled by the vEtolians in the heart of Peloponnesus, with no other view than to humble their antagonists the Achaeans. In the latter they held out, with the assistance only of the Eleans and Lacedemonians, for the space of three years, against the united forces of Achaia and Macedon; but were obliged at last to purchase a peace, by yielding up to Philip all Acarnania. As they parted with this pro¬ vince much against their will, they watched all opportu- T O A F F 209 r ; nities of wresting it again out of the Macedonian’s hand ; >r-l.vL',fbr which reason they entered into an alliance with Rome ainst him, and proved of great service to the Romans in their war with him; but growing insolent on account of their services, they made war upon the Romans them¬ selves. By that warlike nation they were overcome, and granted a peace on the following severe terms :—1. The majesty of the Roman people shall be revered in all jEtolia. 2. -ditolia shall not suffer the armies of such as are at war with Rome to pass through her territories, and the enemies of Rome shall be likewise the enemies of iEtolia. 3. She shall, in the space of 100 days, put into the hands of the magistrates of Corcyra all the prisoners and deserters she has, whether of the Romans or their allies, except such as have been taken twice, or during her alliance with Rome. 4. The iEtolians shall pay down in ready money, to the Roman general in iEtolia, 200 Euboic talents, of the same value as the Athenian talents, and engage to pay 50 talents more within the six years following. 5. They shall put into the hands of the consul 40 such hostages as he shall choose, none of whom shall be under 12, or above 40 years of age : the pretor, the general of the horse, and such as have been already hostages at Rome, are excepted out of this number. 6. iEtolia shall renounce all pretensions to the cities and territories which the Romans have conquered, though these cities and terri¬ tories had formerly belonged to the iEtolians. 7. The city ofOenis and its district shall be subject to the Acarnanians. After the conquest of Macedon by iEmilius Paulus, they were reduced to a much worse condition; for not only those among them who had openly declared for Per¬ seus, but such as were only suspected to have favoured him in their hearts, were sent to Rome, in order to clear themselves before the senate. There they were detained, and never afterwards suffered to return into their native country. Five hundred and fifty of the chief men of the nation were barbarously assassinated by the partisans of Rome, for no other crime than that of being suspected to wish well to Perseus. The iEtolians appeared before Emilius Paulus in mourning habits, and made loud com¬ plaints of such inhuman treatment, but could obtain no redress; nay, ten commissioners, who had been sent by the senate to settle the affairs of Greece, enacted a de¬ cree, declaring that those who were killed had suffered justly, since it appeared to them that they had favoured the Macedonian party. From this time those only were raised to the chief honours and employments in the iEto- lian republic who were known to prefer the interest of Rome to that of their country ; and as these alone were countenanced at Rome, all the magistrates of iEtolia were the creatures and mere tools of the Roman senate. In this state of servile subjection they continued till the de¬ struction of Corinth and the dissolution of the Achaean league, when iEtolia, with the other free states of Greece, was reduced to a Roman province, commonly called the province of Achaia. Nevertheless, each state and city was governed by its own laws, under the superintendency of the pretor whom Rome sent annually into Achaia. The whole nation paid a certain tribute, and the rich were for- bidden to possess lands anywhere but in their own country. ' In this state, with little alteration, TEtolia continued under the emperors till the reign of Constantine the Great, who, in his new partition of the provinces of the empire, divided the western parts of Greece from the rest, calling them Neiv Epirus, and subjecting the whole coun¬ try to the prcefectus preetorii for Illyricum. Under the successors of Constantine Greece was parcelled out into several principalities, especially after the taking of Con¬ stantinople by the western princes. At that time The- , VOL. II. odorus Angelus, a noble Grecian of the imperial family, Afer seized on iEtolia and Epirus. The former he left to Mi- II ehael his son, who maintained it against Michael Palaeo- Affiance, logus, the first emperor of the Greeks, after the expulsion of the Latins. Charles, the last prince of this family, dy¬ ing in 1430 without lawful issue, bequeathed fEtolia to his brother’s son, named also Charles ; and Acarnania to his natural sons Memnon, Turnus, and Hercules. But great disputes arising about this division, Amurath II., after the reduction of Thessalonica, laid hold of so favourable an op¬ portunity, and drove them all out in 1432. The Maho¬ metans were afterwards dispossessed of this country by the famous prince of Epirus, George Castriot, commonly called Scanderbeg, who with a small army opposed the whole power of the Ottoman empire, and defeated these barbarians in 22 pitched battles. That hero at his death left great part of fEtolia to the Venetians ; but they not being able to make head against such a mighty power, the whole country was soon reduced by Mohammed II. wRose successors hold it to this day. AFER, Domitius, a famous orator, born at Nismes, flourished under Tiberius, and the three succeeding em¬ perors. Quintilian makes frequent mention of him, and commends his pleadings. But he disgraced his talents, by turning informer against some of the most distinguish¬ ed personages in Rome. Quintilian, in his youth, culti¬ vated the friendship of Domitius very assiduously. He tells us that his pleadings abounded with pleasant stories, and that there were public collections of his witty say¬ ings, some of which he quotes. He also mentions two books of his On Witnesses. Domitius was once in great danger from an inscription he put upon a statue erect¬ ed by him in honour of Caligula, wherein he declared that this prince was a second time consul at the age of 27. This he intended as an encomium, but Caligula taking it as a sarcasm upon his youth and his infringe¬ ment of the laws, raised a process against him, and pleaded himself in person. Domitius, instead of making a defence, repeated part of the emperor’s speech with the highest marks of admiration; after which he fell upon his knees, and begging pardon, declared that he dreaded more the eloquence of Caligula than his imperial power. This piece of flattery succeeded so well, that the emperor not only pardoned, b*t also raised him to the consulship. Afer died in the reign of Nero, a. d. 59. AFFA, a weight used on the Gold Coast of Guinea, equal to an ounce : the half of it is called eggeba. Most of the blacks on the Gold Coast give these names to these weights. AFFECTION, in a general sense, implies an attribute inseparable from its subject. Thus magnitude, figure, weight, &c. are affections of all bodies; and love, fear, hatred, &c. are affections of the mind. Affection is a term used by various writers on Moral Philosophy to denote all those active principles whose di¬ rect and ultimate object is the communication either of enjoyment or of suffering to any one of our fellow-creatures. (Stewards Philosophy of the Active Powers, vol. i. p. 75.) Affection, among physicians, is the same as disease. Thus, hysteric affection is the same as hysteric disease. AFFERERS, or Afferors, in Law, persons appointed in courts-leet, courts-baron, &c. to settle, upon oath, the fines to be imposed upon those who have been guilty of faults arbitrarily punishable. AFFETTUOSO, or Con Affetto, in the Italian music, intimates that the part to which it is added ought to be played in a tender, moving way, and consequently rather slow than fast. AFFIANCE, in Law, denotes the mutual plighting of troth between a man and woman to marry each other. 2 D 1 210 A F G A F G Affidavit AFFIDAVIT signifies an oath in writing, sworn before li . some person who is authorized to take the same. tan1113" AFFINITY, among civilians, implies a relation contract- ed by marriage, in contradistinction to consanguinity, or relation by blood. Affinity does not found any real kin¬ ship ; it is no more than a kind of fiction, introduced on account of the close relation between husband and wife. It is even said to cease when the cause of it ceases: hence a woman who is not capable of being a witness for her husband’s brother during his lifetime, is allowed for a wit¬ ness when a widow, by reason the affinity is dissolved. Yet with regard to the contracting of marriage, affinity is not dissolved by death, though it be in every thing else.— There are several degrees of affinity, wherein marriage was prohibited by the law of Moses : thus, the son could not marry his mother, or his father’s wife (Lev. xviii. 7. et seq.) ; the brother could not marry his sister, whether she were so by the father only or by the mother only, and much less if she was his sister both by the same father and mother; the grandfather could not marry his grand-daughter, either by his son or daughter. No one could marry the daughter of his father’s wife; nor the sis¬ ter of his father or mother; nor the uncle his niece ; nor the aunt her nephew; nor the nephew the wife of his uncle by the father’s side. The father-in-law could not marry his daughter-in-law; nor the brother the wife of his brother while living, nor even after the death of his brother if he left children. If he left no children, the surviving brother was to raise up children to his deceased brother, by marrying his widow. It was forbidden to marry the mother and the daughter at one time, or the daughter of the mother’s son, or the daughter of her daughter, or two sisters together. Affinity is also used to denote conformity or agree¬ ment. Thus we say, the affinity of languages, the affinity of words, the affinity of sounds, &c. Affinity, in Chemistry, a term employed to express that peculiar propensity which the particles of matter have to unite and combine with each other exclusively, or in pre¬ ference to any other connection.—The attractions between bodies at insensible distances, and which of course are con¬ fined to the particles of matter, have been distinguished by the name of affinity; while the term attraction has been more commonly confined to cases of sensible distance. AFFIRMATION, in Logic, the asserting of the truth of any proposition. Affirmation, in Law, denotes an indulgence allowed to the people called Quakers, who, in cases wdiere an oath is required from others, may make a solemn affirma¬ tion that what they say is true; and if they make a false affirmation, they are subject to the penalties of perjury. But this relates only to oaths taken to the government, and on civil occasions; for Quakers are not permitted to give their testimony in any criminal case, &c. Affirmation is also used for the ratifying or confirm¬ ing of the sentence or decree of some inferior court. Thus we say, the house of lords affirmed the decree of the chan¬ cellor, or the decree of the lords of session. 'Ua. n. ■v AFFIRMATIVE, in Grammar. Authors distinguish affirmative particles, such as yes. The term affirmative e is sometimes also used substantively. Thus we say, the affirmative is the more probable side of the question: there ^ ^ were so many votes, or voices, for the affirmative. , AFFIX, in Grammar, a particle added at the close of a word, either to diversify its form or alter its signification. We meet with affixes in the Saxon, the German, and other northern languages, but more especially in the Hebrew, and other oriental tongues. The Hebrew affixes are single syllables, frequently single letters, subjoined to nouns and verbs, and contribute not a little to the brevity of that language. The oriental languages are much the same as to the radicals, and differ chiefly from each other as to affixes and prefixes. AFFLATUS literally denotes a blast of wind, breath, or vapour, striking with force against another body. The word is Latin, formed from ad, to, and flare, to blow. Naturalists sometimes speak of the afflatus of serpents. Tully uses the word figuratively, for a divine inspiration; in which sense he ascribes all great and eminent accom¬ plishments to a divine afflatus. The Pythian priestess being placed on a tripod or perforated stool, over a holy cave, received the divine afflatus, as a late author expres¬ ses it, in her belly; and being thus inspired, fell into agi¬ tations, like a phrenetic; during which she pronounced, in hollow groans and broken sentences, the will of the Deity. This afflatus is supposed by some to have been a subterraneous fume or exhalation, wherewith the priestess was literally inspired. Accordingly, it had the effects of a real physical disease, the paroxysm of which was so vehement, that, Plutarch observes, it sometimes proved mortal. Van Dale supposes the pretended enthusiasm of the Pythia to have arisen from the fumes of aromatics. AFFORESTING, Afforestatio, the turning of ground into forest. The Conqueror and his successors continued afforesting the lands of the subject for many reigns, till the grievance became so notorious, that the people of all degrees and denominations were brought to sue for relief; which was at length obtained, and commissions were granted to survey and perambulate the forest, and sepa¬ rate all the new-afforested lands, and reconvert them to the uses of their proprietors, under the name and quality oHpurlieu or pouralle land. AFFRAY, or Affrayment, in Law, formerly signified the crime of affrighting other persons, by appearing in un¬ usual armour, brandishing a weapon, &c.; but at present aff ray denotes a skirmish or fight between two or more. AFFRONTEE, in Heraldry, an appellation given to ani¬ mals facing one another on an escutcheon ; a kind of bear¬ ing which is otherwise called confrontee, and stands opposed to adossee. AFFUSION, the act of pouring some fluid substance on another body. Dr Grew gives several experiments of the luctation arising from the affusion of divers men- struums on all sorts of bodies. Divines and church his¬ torians speak of baptism by affusion, which amounts to much the same with what we now call sprinkling. AFGHANISTAN, A N extensive and powerful kingdom of Asia, which YjL formed at one time a considerable portion of the Mogul empire. On the decline of that power, it rose to the rank of an independent state ; and from its population and extent, and still more from the character of the peo¬ ple, who are brave, hardy, and enterprising, as well as from its commanding position in the heart of Asia, it soon acquired political importance, and has since acted a prin¬ cipal part in all the revolutions which have occurred either in Hindostan or in Persia. It is only of late years that Europeans have obtained any authentic account of this interesting country. In AFGHANISTAN. • 1793 Mr Foster, in the course of an overland journey from AfyniS‘ jn(ya’ jn which he was exposed to the greatest danger the predatory habits and religious prejudices of the people, succeeded in penetrating into those mountainous regions. He visited the cities of Cashmere, Cabul, and Candahar, respecting which his information is equally curious and instructive. But the most complete and sa¬ tisfactory account of Afghanistan is derived from the work of Mr Elphinstone, by whom it was visited in 1808. It was supposed that about this time the French were me¬ ditating an invasion of British India ; and Afghanistan be- inf in a manner one of the outworks of Hindostan through which an invading army must make its approaches on the north, it was judged necessary to apprize the sovereign of his danger, in order to secure his co-operation against the common enemy. With this view a mission was sent to him by the British government, at the head of which was Mr Elphinstone, who, along with the other members of the embassy, determined, with a laudable and enlighten¬ ed zeal, to profit by so favourable an opportunity for col¬ lecting information respecting the geography and pro¬ ductions of the country, the manners of the people, and their condition, character, and habits ; on all which sub¬ jects they have accordingly furnished the most satisfac¬ tory and ample details. From the valuable materials fur¬ nished by those travellers, the following account has been chiefly composed. Bouia. It is extremely difficult to fix the boundaries of this ries. country, which frequently extend into wild mountainous tracts, or into deserts, where no definite line of demarca¬ tion is to be found, either political or natural. Its boun¬ daries are also apt to fluctuate, from the constant warfare of the frontier tribes, who own but a very imperfect alle¬ giance to their monarch, whoever he may be, and who by their lawless inroads continually encroach on his do¬ minions. Afghanistan, in the era of its greatest prospe¬ rity, extended to 16 degrees of longitude from Sirhind, about 150 miles from Delhi to Meshed, and about the same distance from the Caspian Sea. In breadth it extended from the Oxus to the Persian Gulf, a space of 910 miles. But its territories have been greatly reduced by war ; and the authority of the sovereign, even in many of those countries which are included within his dominions, is but feebly acknowledged. In defining the irregular limits of this diminished kingdom, we may premise, that from the east of Bengal, in long. 90°, to Herat, in long. 62°, a vast chain of mountains, which tower above the level of per¬ petual snow, extends under the names of the Himalaya, Hindoo Coosh, and Paropamisus. The country of the Afghans is bounded on the north by this great moun¬ tain wall, which from Cashmere, the eastern limit of Afghanistan, takes a south-west direction as far as the snowy peak of Hindoo Coosh, nearly north of Cabul, from which the whole range derives its name. From this peak the same chain, with a lower declination, extends westward, under the name of the Paropamisan Mountains, 350 miles to Herat, and thus completes the northern boundary of Afghanistan. On the east the Indus is the boundary so long as the river continues near the hills, which is as far as lat. 32. 20. The plain on the western bank of the river to the south of this is inhabited, not by the Afghans, but by the Beloches, an independent tribe, and intervenes between die Afghan territory and the river. The Soliman Mountains, therefore, which are a branch from the Hindoo Coosh, running south-south-east along the course of the Indus, with their subordinate ranges, and the plain immediately at their base, are includ- ; ed in the country of the Afghans, and form here its eastern boundary. In lat. 29° north, where the Soliman Moun¬ 211 tains terminate, this plain extends westward, and has new Afghanis- boundaries. On the north it has hills which stretch east tan. and west at right angles to the Soliman range; and those hills form the southern boundary of Afghanistan, sepa¬ rating it from the low and hot plain of Cutch Gundawa or Seweestan on the south. The southern frontier of the Afghan country is extremely irregular. Before reach¬ ing the table-land of Kelat, in long. 66° E., it recedes towards the north, and extends west as far as the desert, which separates it on the north-west from Persia. The Afghans have no general name for their country but that of Afghanistan, which, Mr Elphinstone thinks, was pro¬ bably first employed in Persia. It is frequently used in books, and is not unknown to the inhabitants. It is some¬ times known under the appellation of the kingdom of Cabul. Afghanistan to the west of the Soliman Mountains, Aspect of which form an eastern barrier, may be described generally the coun- as a table-land, lying higher than most of the neighbour-tr75 moun- ing countries. The Hindoo Coosh Mountains, its northern'■f1”8’ anc* bulwark, overlook the low country of Balk, the ancientnvers‘ Bactria, formerly a province of Persia, and inhabited by the Usbeck Tartars. On the east it is equally elevated above the lower plains of the Indus. On the south it overlooks Seweestan; and on the south-west a deep val¬ ley runs between it and Belochistan. It slopes gra¬ dually to the west, and loses the appearance of elevation as it approaches the Paropamisan Mountains. The mountainous chain of Hindoo Coosh is a continuation of the great Himalaya ridge, which it rivals in grandeur and elevation. From the elevated plains of Afghanistan these mountains are seen on the north in four distinct ranges. The first and lowest had no snow in February, when it was observed by Mr Elphinstone from the plain of Peshawer; but the tops of the second still had their winter covering, and the third had snow half-way down. The fourth and highest range is covered with snow at all seasons. It is of great elevation, some of its peaks rising, according to measurement, to the height of 20,493 feet, and is conspicuous from Bactria, from the borders of In¬ dia, and from places in Tartary at the amazing distance of 250 miles. “ The stupendous heights of these moun¬ tains,” says Elphinstone, “ the magnificence and variety of their lofty summits, the various nations by whom they are seen, and who seem to be brought together by this common object, and the awful and undisturbed solitude which reigns amid their eternal snows, fill the mind with an admiration and astonishment which no language can express.” The inferior ranges of the Hindoo Coosh Mountains decrease in height according to their distance from the principal chain. The title of table-land, which has been applied to Afghanistan, if it is understood to imply any thing more than that it is raised above the level of the surrounding regions, will convey a very inaccurate idea of the nature of the country, which, so far from be¬ ing a plain, is of the most diversified surface, being inter¬ sected everywhere with chains of mountains, which di¬ verge in various directions from the main ridge of Hindoo Coosh. We will not enter into any detailed description of this complicated mass of mountains, which, however accurate, would fail to present any very clear view of the topography of the country. It may be generally stated, that the ridges branch off southward, not exactly at right angles from the main ridge, but in irregular lines, to the distance of 60 or 70 miles, when they decline to a lower level; and that those ridges are separated by intervening valleys, each of which is watered by a river flowing down the southern declivity of the Hindoo Coosh Mountains into the Cabul, which, after an easterly course along 212 AFGHANISTAN. Afghanis- the base of the mountains of about 350 miles, joins the tan. great Indus. These valleys or glens all open from the south into the great valley of Cabul; and the country is described as being fertile, and of a pleasing appearance. On the lower hills by which the valleys are closed in, the snow generally lies for four months in the year; there are few trees on the tops, but their sides are covered with forests of pine, oak, and wild olive. Lower down, the country improves, and is interspersed with many little valleys, watered by clear and beautiful streams, and enjoying a delicious climate, under which European fruits and flowers grow wild in the utmost variety and perfec¬ tion ; and even the rocks add to the beauty of the scene¬ ry, from the rich verdure of mosses with which they are covered. The narrow and alluvial plain at the bottom, through which the river runs, is in general highly pro¬ ductive. The valley of the river Swaut, which may be taken as a sample of all the others, yields two harvests, and produces most sorts of grain; and on the plains are numerous mulberry trees and planes, besides other fruit- trees improved by culture. Westward from the Indus about 150 miles, an immense curve or angle projects southward from the mountain barrier of the country into the interior to the distance of 70 miles, when the snowy mountain abruptly descends into the low and hot plain of Jellalabad. The range then resumes its westerly course, when lower hills assume their former appearance and character, and form the Co- histan or high lands of Cabul, a country watered by the river of this name and its tributary streams, and described as fruitful and of a delightful aspect. The Paropamisan chain bounds this country on the west, and forms a maze of mountains, of which the most intimate knowledge would scarcely be able to trace the plan. They afford a habi¬ tation to some wandering and predatory tribes. This ge¬ neral description applies to that portion of the country from east to west which extends southward about 100 or 150 miles from the Hindoo Coosh Mountains. Beyond this the aspect of the country is varied by the range of the Soliman Mountains, which, commencing with Suffaid Coh, or the White Mountain, so called from the snow with which it is covered at all seasons, extend south- south-west almost parallel to the course of the Indus. These mountains decline towards the west by lower ridges, which run nearly in the same direction as the main ridge ; while other ridges branch off eastward toward the Indus. The height of these mountains is greatly in¬ ferior to that of the Plindoo Coosh; but it is still great, as they are covered with snow to the end of spring, which, in the latitude of 31 degrees, gives a considerable altitude. Beyond the Soliman ridges on the west, the country consists for the most part of high and bleak downs, interspersed with moderate hills; in some places desert and ill cultivated, bare and open, better fitted for pasturage than for the plough, and inhabited by migratory tribes of shepherds. There are exceptions, however, to this general description. In the country which is watered by the Helmund and its tributary streams are found many fertile and delightful spots, which afford pleasant retreats to the shepherds, and pasturage to their flocks. The country round Candahar is fertile and highly culti¬ vated ; but to the south, and especially as it recedes west from the Helmund, it is a complete desert. Livers. Afghanistan has few large rivers for a country of such extent, and so interspersed with mountains. With the exception of the Indus, there is not one which is not fordable throughout its course for the greater part of the year. They partake generally of the character of moun¬ tain torrents, swelling rapidly, and running off; or they are sometimes all drained away for the irrigation of the A fields. The Indus, the eastern boundary of the country, from its volume of water, and the length of its course 1 which has Been traced 1350 miles from its mouth, and which has its source much higher, may be reckoned one of the greatest rivers in the world. Of the rivers of Af¬ ghanistan it alone is navigable, though little use is made of it for this purpose. All the rivers of this country which take their rise in the Hindoo Coosh Mountains are tributary to this great stream. The Cabul is the drain of all the waters which fall on the southern declivity of the Hindoo Coosh Mountains. The most important river which it receives is the Kaushkhaur, which has its rise beyond the Hindoo Coosh range, in the same snowy peak which contains the sources of the Oxus. It rushes with surprising violence into the valley of the Cabul river, which it joins about 100 miles west of the Indus. Lower down, the Indus is joined by the Koorum from the west. The only river south of this which runs into the Indus is the Gomul, which, however, unless when it is swollen by the rains, never reaches its destination, being generally consumed in the irrigation of the country. The greatest of the rivers which run through the rest of Afghanistan is the Helmund or Etymander. This river is the drain of that extensive slope which lies between the Soliman and the Paropamisan Mountains. It has its rise in the latter, and running a south-west course of 400 miles, terminates in the Lake Seestan. The Urghundaub rises 88 miles north-east of Candahar, and after passing within a few miles of that city, joins the Helmund. It is never more than 150 yards broad. The Kashrood, which is a larger river, joins the Helmund after a course of 150 miles. The Furrahrood is a still larger stream; it has a course of 200 miles, and it is uncertain whether it reaches the Lake of Seestan, or is lost in the sands. The Turnuk is a tributary of the Urghundaub, which it joins about 75 miles west of Candahar. It is a rapid torrent, and re¬ ceives the Urghessaun and other smaller rivers. Not¬ withstanding these additions, its stream rather decreases, being consumed in the irrigation of the country, or in the parched and barren sands through which it passes. The Lera, which rises in the south of Afghanistan, has a west¬ ern course from the Soliman Mountains of 200 miles, where it disappears before it reaches the Helmund. The climate of Afghanistan is extremely various, owing ( to the height and inequality of its surface. According to ! its latitude, which is between the 29th and 35th degrees, it should have a decidedly hot temperature; but the ge¬ neral law of climate is here modified by the elevation of i the ground, and great diversities of heat and cold are ac¬ cordingly experienced within a very limited space. The mountainous nature of the country also occasions peculi¬ arities in its climate, and distinguishes it in some degree from that of the adjacent regions. In almost all the countries of Asia within the same latitude as Afghanistan, one important circumstance in their climate is the season and quantity of the periodical rains. Throughout the greater part of India the rainy season is ushered in by the south-west monsoon, which drives the rolling clouds from the ocean on the land, where they descend in rains. The monsoon is earlier in the south of India, and in the vicini¬ ty of the ocean, than in the north, and the rains are heavier. In many cases the opposition of mountains in the interior either arrests entirely the progress of the clouds,. or it varies their direction; and hence large tracts of country are exempted from, or only partially experience, the influence of the monsoons. Before they make their way from the Indian Ocean to Afghanistan, these periodi¬ cal tempests are greatly moderated, having to traverse ate.; AFGHANISTAN. if i us- the whole extent of Bengal in their progress to the Hima- i lava Mountains, when they are forced by this impassable ^ ^ barrier out of their original course towards the south¬ east and afterwards towards the east by the range of Hindoo Coosh; and it is from that quarter that such parts of Afghanistan as are exposed to the monsoon receive the periodical rains. But the clouds are exhausted as they pass on westward to this country, the rains gradually be¬ come less heavy, and are at last merely sufficient to water the mountains, without much affecting the plains below. In the north-eastern districts of Afghanistan, near the Indus, the countries under the range of Hindoo Coosh have their share of the rains; but 50 miles west, in the valley of Swaut, the season of the monsoon is merely a month of clouds, with occasional rains; and in the plain ci Peshawer, which is other 50 or 60 miles farther west, and in some of the valleys to the south, it appears only in some clouds and showers : it is still less felt in the valley of the Cabul river. But the passing clouds being opposed by the southern projection of the Hindoo Coosh Mountains and the Soliman range, collect over some of the plains below, which are accordingly plentifully deluged with the periodical rains. In the country of Damaun, eastward of the Soliman Mountains, along the Indus, the monsoon prevails; as also generally in the southern parts of the country. But it varies greatly in different countries, being merely in some parts a month of clouds with showers. Its influence is less felt towards the north. Besides the par¬ tial influence of the south-west monsoons to which the eastern and southern provinces of Afghanistan are expos¬ ed, it has the winter and the spring rains, which are of great consequence to agriculture in all those countries between the Indus and the Hellespont which are not subjected to the full effect of the south-west monsoon. The temperature of Afghanistan varies of course with the difference of level, and also from local causes. It is affected by the direction of the prevailing winds, some blowing over snowy mountains, others being heated in sum¬ mer and rendered cold in winter by their passage over deserts and arid tracts of great extent. The heat of summer is refreshed in some places by the breezes from moister countries, and others are so environed with hills as to be sheltered from all winds. Thus, throughout this extensive country, great diversity of temperature takes place often within very short distances. In the Hindoo Coosh Mountains perpetual winter reigns, and among the lower ranges snow frequently lies for four months in the year. In the plain of Peshawer, which is within view of these snowy summits, the thermometer in summer rises as high as in the hottest parts of India. It is mentioned by Mr Elphinstone, that in a tent artificially cooled, the ther¬ mometer stood for several days of summer at 112° and 118° in the shade. But the heat is not so uniform, nor does it last so long, as that of an Indian summer. At intervals in June and July cold north-west winds set in, which refresh the air, and render it pleasant. The last half of September is so cold as to be counted among the winter months, and the cold continues to increase till February. But the win¬ ter is not severe ; and though there is frost in the night, it is always dispelled during the day by the influence of the sun. The temperature of the different valleys de¬ pending in this manner on their respective levels, they frequently exhibit the most remarkable contrasts of heat and cold. The plain of Jellalabad during summer is in¬ tolerably hot, while to the south, and immediately above ’h ’be mountain of Suffaid Coh lifts its snowy summit to the clouds. To the north the nearest hills are cold; and in the distance the Hindoo Coosh Mountains are seen skirting the horizon with a bright outline of perpetual 213 snow, while the taole-land of Cabul, immediately to the Afghanis- west, enjoys the coolness and. verdure of a temperate tan. summer. Among the Soliman Mountains, the higher countries are exposed to severe cold; but there are some of the lower valleys where the heat is even greater than at Peshawer. The low plains of Damaun, which run along the shores of the Indus, are oppressed during summer by scorching heats both night and day. On the western plains heat predominates, and they are accordingly de¬ serted in the summer by the wandering shepherds, for the cool retreat and grassy valleys of the mountains. At Candahar the heat of summer is excessive, and is oc¬ casionally aggravated by the simoom winds. In proceed¬ ing north-east, however, along the course of the Helmund and its tributary streams, we reach elevated ground, where the cold is excessive, and where winter is experienced in all its severity. If we ascend the course of the Turnuk to Ghuzni, we find the snow lying deep for some time after the equinox, and so thick a covering of ice on the rivers as to afford a passage for camels. At Cabul the winter is more steady and severe than in England, while the summer heat is greater. The great difference between the seasons, and the quickness with which they change, are marked by the changes which take place in the dress of the inhabitants. In winter they wear woollen garments, and in some places clothes of felt, and over these a large great¬ coat of well-tanned sheep-skin with the long shaggy wool inside. With the vernal equinox the snow disappears, the country is covered with young grass, the buds burst forth, and are soon followed by a profusion of flowers; and the in¬ habitants change their winter dress for a thin one of chintz or cotton, and frequently sleep at night under trees in the open air. The prevailing winds throughout Afghanistan are from the west, and they are generally cold ; while the easterly wind is hot, and brings clouds. On the whole, the climate of this extensive country seems little subject to rains, clouds, or fogs; and judging from the size and strength of the inhabitants, it must be considered salubri¬ ous. Some fatal diseases are, however, common; such as fevers and agues, which prevail in autumn and in spring; also colds, which are sometimes dangerous in winter ; and the small-pox, which still carries off many persons, though the practice of inoculation has long been introduced in all parts; and lastly, the ophthalmia. Afghanistan abounds in wild animals, which find ample Animals, range in the extensive forests and large tracts of unfre¬ quented deserts which it contains. The lion, however, though so common in Persia, and though it has been lately found in such numbers in Guzerat, and in the Hurriana, north-west of Delhi, is rare. In the hilly country around Cabul there is a small animal which bears the name with¬ out any of the qualities of the lion. In the districts east of the Soliman range tigers and leopards are common, and they are to be found in most of the woody tracts of the country. Wolves, hyenas, jackals, foxes, hares, porcupines, and hedgehogs, are to be seen everywhere. The wolves are formidable during the winter in the cold parts, where they assemble in troops, destroying cattle, and frequently attacking men. The hyenas sometimes attack a bullock singly, and, as well as the wolves, they make great havock among the sheep. Bears of two kinds, the one the black bear of India, and the other of a dirty white, are quite common in all the woody mountains; but they rarely leave their haunts, except when they are tempted by the sugar-cane. There are also mangooses, ferrets, and wild dogs. Monkies are common in the north-eastern parts. The wild boars of Persia and India are seldom seen ; and the wild ass is confined to the south-western districts, on the lower Helmund, and to the sandy country round Can- 214 AFGHANISTAN. Afghanis- dahar. The mountains abound with many kinds of deer, tan. including the elk ; but the antelopes are rare, and confin¬ ed to the plains. A species of deer is seen, which is re¬ markable for the size of its horns, and the strong but not disagreeable smell of its body. The king.is in possession of a few elephants ; but neither that animal nor the rhi¬ noceros is to be found in any part of the country. Among the domestic animals is the horse, a consider¬ able number of which is bred in the Afghan dominions ; and those bred near Herat are very fine, uniting the figure of the Arab horse with superior size. In general, however, the breed of Afghan horses is not good. There is a very strong and useful breed of ponies. On the other hand, the mules and asses are the most wretched that can be conceived. The camel is the animal most employed in carrying burdens. The dromedary, the tall long-legged animal common in India, is found all over the plains. The Bactrian camel, with two distinct humps, which is lower than the other by one-third, but stout, and covered with shaggy black hair, is much more rare, and is brought from the country beyond the Jaxartes. Buffaloes are to be found in many parts; and oxen are universally em¬ ployed in the plough, and sometimes camels. They are not reared in the country, but are imported from the Raj¬ poot States, where they are the best in India. The sheep forms the principal stock of the pastoral tribes: it is re¬ markable for a tail about a foot in breadth, and consisting almost entirely of fat; in other respects it resembles the English sheep. The goat abounds in all the mountains, and is not scarce in the plains. Some of the breeds have remarkably long and curiously twisted horns. The pas¬ toral tribes in the country, who are extremely fond of hunting, breed great numbers of excellent greyhounds, and even pointers, resembling those in England both in shape and quality. There is a breed of long-haired cats in great esteem, and of which great numbers are exported. Of the birds, there are three sorts of eagles, and many kinds of hawks; namely, the gentle falcon, a large grey short-winged bird; the gos-hawk; the shauheen, which soars over the falconer’s head, and strikes the quarry as it rises; and the chirk, which is trained to strike the an¬ telope, and, by fastening on its head, to retard its flight till the greyhounds come up. The other birds are, he¬ rons, cranes, storks, wild ducks, geese, swans, partridges, quails, and a bird known in Europe under the name of the Greek partridge. There is another smaller bird resem¬ bling it, which is found nowhere except in Afghanistan. Pigeons, doves, crows, and sparrows, are common in all countries. Cuckoos, which are rare, and magpies, which are unknown in India, abound in the colder climate of those northern mountains ; while peacocks, so commonly found wild in India, are here seen only in their domesticated state. Parrots make their appearance in the eastern pro¬ vinces near the Indus. The country is not infested with venomous reptiles. The snakes are mostly harmless; and though in Pesh- awer the scorpions are noted for their size and venom, their bite is scarcely ever fatal. There are no crocodiles, but there are turtles, as well as tortoises. In Khorassan, great flights of locusts have sometimes occasioned famine by their devastations, though this rarely occurs. Mus- quittoes are less troublesome than in India, except in the southern district of Seestan, where they sting as severely as in Bengal. In most parts of Afghanistan there are two harvests, one in spring and the other in autumn. In the countries west of the Soliman range the former is the most import¬ ant; but in the eastern parts the autumn harvest is the most considerable. The produce of the first, which is anil. sown in spring and reaped in autumn, is wheat, barley a peas, beans, and other grains; that of tfie second, sown in the end of spring and reaped in autumn, is rice, IndianS{% corn, and various kinds of pulse. Cotton is confined to theC|ill hot climates, and sugar is cultivated in some of the rich P: lets, plains. Tobacco is produced in most parts. There is another distinct harvest, which is counted of great import¬ ance, of musk-melons, water-melons, the scented melon and various sorts of cucumbers, pumpkins, and gourds' which are grown in the open fields. All common garden- stuff’s are abundant, “such as carrots, turnips, beetroot lettuce, onions, garlic, spinnage, greens of all kinds, cal> bages, cauliflowers, and many of the Indian vegetables. The castor oil plant is found everywhere. Madder abounds over all the western provinces, and the assafeetida plant in the hills. In the west, lucerne and a sort of trefoil are among the most important products of husbandry. Of the fruits and trees which abound in tropical countries, few are to be found east of the Soliman range, and none to the west; but almost all the European trees and fruits are indigenous in the congenial climate of those elevated regions. They are frequently found growing wild in different parts of the country, and are still more common in gardens and orchards. The most common trees in the mountains are pines, oaks, cedars, a sort of gigantic cypress, the walnut and the wild olive tree, the birch, the holley, and the hazel. In Hindoo Coosh the pistachio tree grows wild; and on the plains are the mul¬ berry, the tamarisk, and the willow; also the plane and the poplar. English flowers, such as roses, jessamines, poppies, narcissuses, and hyacinths, are found in the gar¬ dens, and often in a wild state. Of the minerals produced in the country little is known.M all Gold is said to be washed down the streams that flow from the Hindoo Coosh Mountains. Small quantities of silver are found in Caffristan; also lead, iron, and anti¬ mony, in different parts ; sulphur and rock-salt in the salt range of mountains, and saltpetre everywhere. The political institutions of the Afghans present theGi rude and disjointed materials of a free constitution. Them< form of the government is patriarchal. The nation is supposed to derive its origin from four tribes, which are divided and subdivided into inferior clans, until the last subdivision does not include more than a few families. The chief of a tribe is called Khan, and is elected in general by the king; while the head of one of the inferior divisions owes his choice to the people. To the khan, among the aristocratic tribes, is committed the collection of the royal revenue and the raising of the militia; and from the exercise of these duties, and the emoluments of his office, he derives extensive power and influence, more especially where he presides over a numerous tribe. Each inferior division of the tribe has its respective head; and in cases of emergency these all meet together and form a general assembly, called a Jeerga, which, with the khan presiding over it, deliberates and decides in all matters of public importance. The heads of the inferior branches of the tribe hold similar assemblies, which de¬ cide on minor matters, and are guided by the same rules as the greater convention. When wars arise among the different tribes, it is the business of the assemblies to pro¬ vide the means of carrying them on, to concert the plan of operations, or to settle the terms of peace. They have the power, along with the khan, to call out all the fighting men of the tribe, or they may levy taxes for any purpose of public utility. There is scarcely a petty community throughout the nation which does not make its own ar¬ rangements for the support of moollahs, an order of Ma¬ hometan priests, and for the maintenance and reception AFGHANISTAN. if„hiis* of strangers into the tribe, whom it is always reckoned a I tai duty to treat with peculiar attention. 1 The Afghan nation consists in this manner of numerous rude democracies, which are formed into one state by the supreme authority of the sovereign. He is the natural head of the tribe of Dooraunee, the greatest, bravest, and most civilized in the nation. He has, besides, a general superintendence over the whole kingdom, and may levy troops or money from each tribe for the common defence. But his authority is not equally respected by all the tribes. In the plains around the towns, throughout a con¬ siderable portion of the country, and in all the foreign provinces, he rules with full power, and collects a revenue and maintains an army without the aid of the khans or the popular assemblies. He employs for this purpose officers of his own appointment, namely, a haukim, wdio collects the revenue and commands the militia; a sirdar, who commands the regular troops, and whose duty it is to enforce submission to the haukim, and to the cauzy, who presides over the administration of justice. The heads of tribes, and under them the heads of the divisions of tribes, act in the revenue and police departments, under the haukim and the sirdar. Where the royal authority is strong, the khans have comparatively little influence; but, on the other hand, where it is weak, it is frequently re¬ sisted by the powerful influence of the khans, who form the aristocracy of the land, as their authority is also resist¬ ed by the inferior assemblies ; and it sometimes happens that those assemblies differ with each other about the limits of their own powers; and hence the democratic tribes are often involved in dissension by this complicat¬ ed collision of rival authorities. In the concerns of some of the tribes the king never interferes; he merely levies supplies of money for the public service, which, notwith¬ standing the presence of one of the royal sirdars, are fre¬ quently withheld or granted, according to the discretion of the khan: and in like manner the khan and the cauzy contend with more or less success, according to the state of the king’s authority, for the exercise of the judicial power. One or two tribes, such as the Eusofzyes, in the eastern corner of the country, set the king at defiance, and boast of their independence. The country is divided into 27 provinces, in 18 of which the royal authority prevails, and the king’s officers, the haukims and the sirdars, constantly reside. These are, Herat, Furrah, Candahar, Ghuzni, Cabul, Baumican and Ghorebund, Jellalabad, Lugh- man, Peshawer, Dera Ismael Khan, Dera Ghauzi Khan, Shekarpoor, Sewee, Sinde, Cashmere, Chuch Hazareh, Leia, and Mooltan. Several of these provinces, owing to the distraction of the country, have since aspired to inde¬ pendence ; and in the other nine the royal authority car¬ ries little weight. The government of the Afghans, though it contains in this manner the elements of freedom, fails entirely in the great end of securing to the community the blessings of good order and peace. The people are bold and inde¬ pendent, and spurn the restraints of law. Among such a variety of independent communities, imperfectly con¬ trolled by the royal authority, wars arise, which are waged 'wth great fierceness, and in which the tumultuary mi- htua of the tribes frequently come to blows, and w^aste each other s territories. Private revenge also, though prohibited by the laws, is sanctioned by manners: it is accordingly practised by all classes, and is accounted the unalienable right of every freeman. Hence family ends arise, which are not only carried on with bitterness at t ie time, but being transmitted from generation to ge- ;;ieraV°n> produce a long-continued course of violence and oodshed. Afghanistan, with its bold and turbulent aristo- 215 cracy, and the rude independence of its people, presents a Afghanis- hvely picture of the state of society in Europe under the extent, owing principally to its physical construction. ^’•vt desert of sand, which in a broad belt stretches quite across the continent, forbade every attempt to pass it until the introduction of the camel by the Arabs. The want of any known great river, except the Nile, that might conduct into the interior, contributed to confine the Greek and Roman colonists to the habitable belt along the northern coast. We know, however, from unquestionable authority, for so we deem the sacred records to be, that 4000 "years ago the grandson of Ham fled to and settled in Egypt or Misraim, names which that country has preserved to the present day; and that3600 years ago it was as well or better known to eastern nations than any part of Europe was at that time. The latter, indeed, may be said to have re¬ ceived the germs of civilisation from the Egyptian colo¬ nies on the shores of the Mediterranean; for we have sufficient proof that Egypt had reached to a considerable degree of civilisation in the patriarchal ages, from the circumstance of the sons of Jacob proceeding thither out of Asia to purchase corn; for a commerce in grain im¬ plies civilisation. The Carthaginians are also known to have formed establishments on the northern coast of Africa at a very early period of history, certainly not less than 2700 years ago ; and the conquest of Egypt by Cam- byses dates as far back as 2300 years. We may con¬ sider, therefore, the coasts of Egypt, of the Red Sea, and of the Mediterranean, to have been settled and well known to the ancient Asiatics, who were constantly pass¬ ing the narrow isthmus which divided their country from Africa, and led them immediately from parched deserts into a fertile valley, watered by a magnificent river. But whether they were much or little acquainted with the western coast, which bounds the Atlantic, and the eastern coast washed by the Indian Ocean, is a question that has exercised the research and ingenuity of the ablest scho¬ lars and geographers, and has not yet been satisfactorily answered. This question being one of curiosity rather than utility, Western we shall only state the case, and the results of the several coast, inquiries, without entering into the merits of the argu¬ ments advanced by the different parties. We are told by Herodotus, that Necho, king of Egypt, sent out an expe¬ dition under the command of certain Phoenician seamen, for the purpose of circumnavigating Africa; and that, on their return, they asserted that they had accomplished this undertaking. Few of the ancient writers give credit to the story; but, among the moderns, the Abbe Paris and Montesquieu have contended that this voymge was actually performed. Isaac Vossius and D’Anville have strong doubts ; and Dr Vincent and M. Gosselin maintain that such an expedition, at such a period, exceeds all the means and resources of navigation, then in its infancy. Last of all comes Major Rennell, who, in his elucidation of the geo¬ graphy of Herodotus, has done more than all the rest in clearing away the doubts of history; and he argues the possibility of such a voyage, from the construction of their ships, with flat bottoms and low masts, enabling them to keep close to the land, and to discover and enter into all the creeks and harbours which any part of the coast might present. At all events, one thing is evident: if such an expe¬ dition ever left the Pillars of Hercules, and proceeded down the coast, the fruits of it have nearly, if not entirely, perished. About half a century after this supposed expedition, the account of another voyage, down the western coast, is contained in the Periplus of Hanno, which has also called forth many learned and elaborate discussions among mo¬ dern geographers. The principal persons engaged in this controversy were Bougainville, Rennell, and Gosselin, the several results of whose researches will be seen in the fol¬ lowing table; the first column of which exhibits the de¬ scription of the successive lines of coast, and their most remarkable features, as given by Hanno, who commences his narrative from the Pillars of Hercules or Straits of Gibraltar. The others show the correspondent modern positions, as severally assigned by these three distin¬ guished geographers. DESCRIPTION OF OBJECTS ON THE COAST, AS GIVEN BY HANNO.

Delisle, Huet, and Bochart, made the discovery of the coast to extend as far south as Mozambique and Ma¬ dagascar. D’Anville could trace such discovery no far¬ ther than to Cape Delgado; and M.

But Dr Vincent, who has entered more pro¬ foundly into the subject than any of his predecessors, and brought a great fund of learning to bear on the question, in his Periplus of the Erythrean Sea, has with great plau¬ sibility extended these boundaries to Mozambique and to the island of Madagascar.

The story told by Herodotus at fourth hand, of some Nasamonians crossing the desert and arriving at the same river, appears to be deserving of very little credit. The abs. The people from whom we derive the first information con- * cerning the interior of Northern Africa are the Arabs, who, by means of the camel, were able to penetrate across the great sandy desert to the very centre of the continent, and along the two coasts as far as the Senegal and the Gambia on the west, and to Sofala on the east. On this latter coast they not only explored to an extent far be¬ yond any supposed limits of ancient discovery, but plant¬ ed colonies at Sofala, Mombas, Melinda, and at various other places. The rtu- The fifteenth century produced a new era in maritime gm discovery. The voyages of the Portuguese were the first to give any thing like an accurate outline of the two coasts, and to complete the circumnavigation of Africa. The discovery of America and the West India islands gave rise to that horrible traffic in African negroes, which has since been carried on without intermission; and this traffic has been the means of acquiring a more extended and accurate knowledge of that part of the coast which lies between the rivers Senegal and the Cameroons, as well as of the manners and character of the people who inhabit this extended line of coast. . The English settle¬ ments along this line gave opportunities for making sur¬ veys, and occasionally of visiting certain portions of the interior. Still more recently, a regular survey has been made by Captain Owen of the navy, between the Cape Guardafui or Guardefan, in the Arabian Sea, to the Cape of Good Hope, and thence continued to the Gulf of Guinea, the completion of which is now (1829) in progress, as far as to the Straits of Gibraltar. Afrit As- The uncertainty and the confusion that prevailed in the •ockiin. geography of the interior of Africa, induced a few learned and scientific individuals to form themselves into an asso¬ ciation for promoting discoveries in the interior of Africa; under whose patronage those important additions made by Houghton, Hornemann, Mungo Park, and Burckhardt were effected, and under which an individual, who had travelled as draughtsman to Mr William Banks, has more recently been employed in exploring the source of the Conf ix- Bahr-el-Abiad. In consequence of an opinion given by pditii. park an(] Maxwell, as to the southern course of the Niger, an expedition was fitted out by the government to explore the source of the river Congo, under the direction of Cap¬ tain Tuckey, the result of which did not add so much to our information respecting that great river and surrounding country as might have been expected, owing to the great mortality of the party, occasioned, as it would seem, more from imprudent exposure and exertion, than from un- V*50' -• healthiness of climate. The next attempt to push disco- Qudl • VeiT 'nto ^le interior of Africa was the mission of Oud- Ea; ney, Denham, and Clapperton, from Tripoli to Bornou, and ([p. under the auspices of government; which was followed up Peru by another under Clapperton, from the Bight of Benin to the same part of the country which he had reached on tile first journey; thus supplying a complete series of ob- I c A. 221 servations for the latitudes and longitudes, from the Medi- Africa, terranean to the Gulf of Guinea. These two expeditionsv V ' have cleared away all those conjectural speculations of the courses of rivers, ranges of mountains, and positions of lakes and cities, many of which are now ascertained to have no existence; while others that do exist are found to have been placed on the maps several hundred miles out of their true situations, to the utter confusion of topo¬ graphical consistency. In short, our maps of this great continent were very little better than those of the six¬ teenth century, wherein, as Swift facetiously says, Geographers, in Afric maps, With savage pictures fill their gaps ; And o’er uninhabitable downs Place elephants for want of towns. In consequence of the recent expeditions and surveys above mentioned, and a variety of other information, we are now in a condition to give a far more accurate and detailed account of this great continent than has appear¬ ed in any former edition of this work. It may be right, however, in the first place, to take a general and com¬ prehensive view of this quarter of the globe, on which will be found to exist many peculiarities to distinguish it from the other continents. Africa is separated from Asia by the Isthmus of Suez, and General from Europe by the Straits of Gibraltar; stretching from the description equator to about the average latitude of 35° N., and also to °* Mrica. the same degree of latitude south. It embraces every va¬ riety of temperature, from extreme heat to the mildest of European climates, the softness and salubrity of the latter of which are experienced in the Barbary States, and at the Cape of Good Hope. On the other hand, its tropical regions, especially on the sea-coast, are most destructive to Europeans who attempt to settle in them, by diseases occa¬ sioned by a rich and swampy soil, clothed with an exuberant vegetation. The greatest length, from north to south, is Dimen- from Cape Serrat in Algiers, in lat. 37. 18. N., to Capesi°ns- Laguillas, in lat. 34. 55. S.; and the greatest breadth, from Cape Verde, in long. 17. 31. W., to Cape Guardafui, in long. 51. 15. E. Its mean length may be estimated at about 4000, and mean breadth at 2000 miles, containing an area of 8,000,000 geographical miles. The northern por¬ tion of this great continent is fully twice the size of the southern portion, and may be considered as about equal to South America. South Africa is contracted to half the width of the northern part, and is, as nearly as may be, about the size of Australia or New Holland. The inspection of a map of the world would induce one to conclude, that the two continents of Africa and America were once united; the bulging part of the former fitting in exactly to the Gulf of Mexico; and the bulging part of South America, about Paraiba and Pernambuco, being about the size and shape to fill up the Gulf of Guinea. Africa has neither the lofty mountain chains nor the Moun- magnificent rivers of the opposite continent of America, tains. Of the mountains, those of the greatest height that are actually known are the great cluster of the Atlas, one chain of which runs southerly to the desert of Zahara, and another easterly to the neighbourhood of the Syr- tes; two or three points of which are said to be per¬ petually covered with snow, which would give them an elevation of from 12,000 to 13,000 feet. The cluster of Abyssinian mountains, on the opposite side, are very simi¬ lar in their shape and grouping to those Of Atlas. Those parts which lie in the provinces of Tigre and Gojam, from being almost constantly covered with snow, may be con¬ sidered as about the same height as those of Atlas. The Kong mountains, which were supposed, and are so drawn 222 AFRICA. Africa. Kivers. in the maps, to run across the continent in one unbroken 'chain near the equator, are of doubtful existence as to their continuity. Where crossed by Clapperton, they no¬ where rose to the height of 3000 feet; but they were of granite; and a few degrees to the southward, and behind the river Cameroons, two or three lofty peaks are visible from the sea, which appear by triangulation to be from 13,000 to 14,000 feet. Along the eastern coast, one conti¬ nued chain extends from the Abyssinian range to the Table Mountain of the Cape of Good Hope, but of no great height, as far as known. Perhaps we may consider the continent of Africa as one great plateau, supported by littoral chains, presenting their steep sides seawards, and sloping gently into the interior, in which many rivers will be found to descend from them, that in all probability never reach the ocean. All the rivers discharged into the Mediterranean, with the exception of the Nile, are small mountain streams. The same is the case from Ceuta along the western coast • to the commencement of the desert, a distance of about eight degrees of latitude. On the coast of the Zahara there are no rivers. The Senegal, the Gambia, and the Rio Grande, are rivers of considerable magnitude, and each has its source in the same system of mountains. But it is into the Gulf of Guinea that the largest rivers of Africa discharge their waters. The Volta, the Benin or Formosa, the Bonny, the Old and New Calabar, the Rio del Rey, and the Cameroons, are all of them large rivers; but nothing is known of them farther than some forty or fifty miles from their mouths, and they have been supposed, except the last two, to be branches of one and the same river. Farther down, and near the equator, are the Angra, the Gaboon, and the Lopez, all of which, with the others, probably derive their sources from the range of lofty peaked mountains which have been mentioned as seen from the sea. Still farther south is the great river Zaire or Congo, and lower down still the Coanza, and a few smaller ones, comprehended within the Portuguese settlements, which extend from about lat. 6. to 16. S. From hence to the Cape of Good Hope, with the exception of the Gariep or Orange River, there is none deserving of notice. On the eastern coast the rivers are much smaller, but more numerous. From the Isthmus of Suez, along the whole coast of the Red Sea, and from Babelmandel to Cape Guardafui, and from this cape to Pattah, in lat. 2. 15. S., opposite to which is the river Obii or Zebee, there is not a stream of any note throughout the distance of 2500 miles. In proceed¬ ing hence southerly we have the Quilimance, Mombas, Monghow or Mongallow, Mozambique, Quiloa, Lindy, Quillimane, Jambeze, Sofala, Inhambane, and Marfooma and Mapoota, which fall into De la Goa Bay. From hence to the Cape of Good Hope a few streams of little importance fall into the Eastern Ocean. Face of the A very short description will suffice to give a general country, outline pf the surface of Africa. Between the Straits of Gib¬ raltar and the Gulf of the Syrtis, which is about two-thirds of the Mediterranean coast, the country exhibits a broken chain of mountains, interspersed with fertile valleys, in width extending between the 35th and 29th parallels, or about 360 miles. The rest of this coast, including Egypt (Vhich, with Abyssinia, extends to the 12th pa¬ rallel), is generally composed of fine fertile hills and dales and valleys, mixed, however, with deserts, in which are a few insulated spots of verdure, known by the name of oases. I his portion of Africa belongs (with the excep¬ tion of Egypt) to the Barbary states of Tripoli, Tunis, Algiers, and Morocco. The next region, proceeding southerly, is the Zahara or great sandy desert, lying be¬ tween the 29th and 16th parallels, or about 780 miles in aL| breadth, and extending across the continent, from the^L Atlantic to the borders of Nubia. It is inhabited only by ^ wandering pastoral tribes, who move about from one oasis to another, where a little verdure may be found. Some of these tribes add, to the scanty means of subsistence, the plunder of such feeble caravans as they may venture to attack, and others are employed in collecting salt and na¬ tron for the markets of Bornou and Soudan. The third region is that of Soudan, or the country of the negroes, extending in a belt quite across the continent as far as Abyssinia, and from the 16th to the 5th parallels, or about 660 miles in width ; a rich and fertile region, yielding, with little labour, all the valuable productions of tropical cli¬ mates. Beyond the latter degree of latitude we are in utter ignorance of what the rest of North, and the whole of South Africa may contain, with the exception of the Cape of Good Hope and the Portuguese settlements on the eastern and the western coasts, between which they are said at one time to have kept up a communication ■ but if so, they have taken good care to keep to them¬ selves whatever knowledge of the intermediate country they might have acquired. The colony of the Cape, on the southern angle, extends not above 500 miles on either coast from that promontory. Thus, then, there still remains a tract of country at the least 30 degrees of latitude, by 25 of longitude, or about 2,600,000" square geographical miles, of which nothing whatever is known. The vegetable productions of a country which embraces Ve? k such a variety of surface, soil, and climate, must neces-prod sarily be very varied. There is, however, a great simi-tio!ls larity in those, both of the vegetable and animal world, which exist in the two temperate extremities; and most of the larger kinds of animals, peculiar to this continent, are found in every part of it, north and south of the line, except perhaps in Egypt, which is too thickly inhabited, and on the broad belt of the desert, where there is nothing for them to subsist on. At the two extremities, the forest trees are not remarkable, either for their exuberance of growth or their utility in naval and civil architecture, ma¬ chinery, or domestic uses. In the valleys, and on the sides of the hills of Mount Atlas, are extensive forests; but in no other part of the northern region. The erythrina, several mimosas or accasias, particularly the mimosa nilotica, numerous species of euphorbia and cactus, of rhamnus, aloe, and the huge adansonia, are found in the most arid soils, even on the great desert, but there in a more dwarfish state. The scanty vegetation, however, that partially appears on the surface of this “ land of perpetual thirst,” this “ leonum arida nutria*” is mostly confined to the more humble tribe of mysembri-anthema, salsolse, salicor- nias, gnaphaliae, and a few other species of saline and suc¬ culent plants, which are able to support a feeble exist¬ ence in a soil unrefreshed by rain or moisture. The southern extremity of Africa enjoys, in addition to the northern Flora, the magnificent family of proteas, and innumerable species of the elegant heaths. The tropical regions, it is almost unnecessary to add, abound with fo¬ rests of the finest timber trees, many of them of dimen¬ sions that can scarcely be credited. The finest naval timber, stated to be superior either to oak or teak, is im¬ ported from the western coast of Africa, chiefly from the neighbourhood of Sierra Leone and the River Gambia. Ihroughout Soudan, wherever there is soil, vegetation is most vigorous, and much more labour is requisite to keep it under, than would be necessary for the cultivation of alimentary and other useful plants, if the ground were once cleared. Those vegetable productions which are raised by the am hand of man, and which administer to his sustenance, his —fiwNothing and shelter, and also to his other comforts, are abundantly supplied, without severe labour, in all parts of this continent, with the exception of the sandy desert. Jn the tropical regions, near the coast, they have the two most useful trees, the cocoa-palm and the common spe¬ cies of palm, which supply them with oil and wine. They have citrons, lemons, oranges, pomegranates, plan¬ tains, and bananas; rice and Indian corn, and various other useful plants, the introduction of some of which they owe to the Portuguese ; perhaps the only benefit con¬ ferred, in compensation for the many evils inflicted by them on this unfortunate people. In the interior they have figs, pomegranates, plantains, abundance of fine yams, melons, gourds, and pumpkins; earth-nuts, coly- cynth, dourrha, and other kinds of millet; maize or Guinea corn, rice, vegetable butter, sweet potatoes, onions,* and pepper. But the dourrha is the grain chiefly cultivated; and from this, with a mixture of pepper and honey, they make the fermented beverage, known in almost every part of Africa under the name of booza, with which the negroes delight to make themselves intoxicated. Cotton and in¬ digo are everywhere cultivated with the greatest ease; and they have plants which afford them dyes of every shade of colour for their cloths. In the temperate parts of the continent, the finest grain of every species is produced, not excluding the maize and millets; every kind of Eu¬ ropean fruits and vegetables, and many of the tropical ones, particularly oranges, lemons, and limes. All the varieties of grapes, figs, peaches, and apricots, are of the richest and most delicious flavour; but apples, pears, plums, and cherries, are found to deteriorate, both at the northern and southern extremities. Melons, pumpkins, and every species of pulse, are as fine as can be produced in any part of Europe. In the northern portion grows the rhamnus lotos or jujube, on which the lotophagi of the ancients are supposed to have fed; and on the skirts of the desert, that most useful tree the date-palm grows in whole forests, affording a very considerable part of the subsistence of the natives. iiima; It would require a volume to name the several objects in the vegetable world. We proceed, therefore, to take a glance at the animal part of the creation ; and first, as Ian. being most important, of its lord and master, Man. The first peopling of any country is always an object of curi¬ ous research, though rarely productive of a satisfactory result. If we admit the grandson of Ham to have settled in Egypt, perhaps we shall not err in considering the rest of Africa, at least of tropical Africa, to have been ori- egro ginally peopled by the negroes, and every other race of «pr man now found on it, whether pure or mixed, to be ad- " venfifi°us. This hypothesis is grounded on the fact, that piu all the people now in Africa, except the blacks, can be traced to an Asiatic origin ; while no negroes were ever found, except as slaves, in Asia, though they are met with on some of the Asiatic islands. Whether this nation, now confined to the tropical regions, were ever in possession ol the two extremities of the continent, it were in vain to inquire; but, considering their indolent disposition, which makes them averse from labour, and anxious to avoid it whenever it is possible, their great delight being to bask in the sun all day, and to sing, dance, drum, and drink booza all night, we may naturally suppose they would make choice ol a country where all the necessaries of life are either produced spontaneously, or with the least possible exer¬ tion of those who are to use them. This is not the case in the extra-tropical regions of Africa, where labour is | required to render the soil productive. It has been con¬ jectured, on grounds slender enough—the features of the fPhythat the ancient Egyptians were negroes; the Africa, lips, however, are the only negro feature in that extraor- dinaiy piece of sculpture. But were it completely negro, it would prove nothing, unless it could be shown that this statue was more ancient than all the temples of Egypt the Memnonium, Epsambul, Tentyra, the tombs of the kings of Thebes, and many others—in all of which the sculpture and the paintings of the human figure are in¬ variably represented with features that approach nearest to the Persians, that original hive, as Sir William Jones has supposed, of the human race, or at least of the greater portion of the orientals. The negroes are by nature a harmless and inoffensive race, and their easy and timid disposition has been turned to their disadvantage, by the facility with which they have suffered themselves, and still submit, to be dragged from their country and friends into a state of foreign slavery. Domestic slavery has undoubtedly existed in all times among the negroes, as well as among other nations, and without being consider¬ ed as an evil; but the peculiarly unfortunate lot of the negro is that of being torn away from all his connections, never to see them again. In the interior, the slaves are as happy and cheerful as their masters, and treated just as well; and strangers are received by them with cheerful¬ ness, kindness, and hospitality. Considering, then, the negroes as the sole aborigines of Africa, and the other races inhabiting this continent as ca¬ pable of being traced to an Asiatic origin, the numbers that have poured in are easily accounted for, by the faci¬ lity with which the Isthmus of Suez afforded them a pas¬ sage, like a bridge, from one continent to the other. They may be classed, according to the purity of their race, as follows: the Berbers, the Moors, the Arabs, and the Turks; of the mixed breeds, the Copts, Nubians, and Abyssinians, are not greatly dissimilar ; the Caffres (Kafirs) or infidels of the eastern coast are obviously of Arab and negro extraction; and the Hottentots, crammed into one single and the most distant corner of Africa, if not an original race, are, it must be admitted, a most singular anomaly among mankind. Of the Jews it is unnecessary to say any thing, as they are scattered over the whole world, and everywhere the same. The Berbers are probably the most ancient inhabitants Berbers, of the northern belt of Africa. The authors of Mithri- dates seem to consider them as the remains of the an¬ cient Getuloe, to the west of Mount Atlas, and of the Libyans to the east. But from whence did these two people proceed? At present they are found in dif¬ ferent parts of the continent under different names. The Shillas in the mountains of Morocco, the Kabyles in the mountains of Algiers and Tunis, the Tibboos in the eastern part of the great desert, and the Tuaricks in the western and central parts of the desert, may all be considered as emanating from the same race. They all speak different modifications of the same language, which, though written in a character wholly distinct (if Oudney be correct) from every other existing, is said to partake of the Hebrew and Phoenician. Mr Marsden, who has paid great attention to the subject, has traced this lan¬ guage from the extreme east to the extreme west of Northern Africa, and conjectures that it may have been the general language of the northern part, antecedent to the period of the Mahometan conquests; and that so marked is its affinity to certain forms of the oriental lan¬ guages, as to make it not unreasonable to consider it as connected with the ancient Punic; an opinion in which M. Dangles is disposed to concur. They are a stout hardy race, of a complexion varying in hue from white to almost black, according to the exposure they have en* n 224 A F R Africa, dured, and the degree of latitude they inhabit. Their form generally well made, tall and thin, their carriage erect and independent. They are most abstemious, their food con¬ sisting chiefly of coarse brown bread, dates, olives, and water. Even on the heated desert, where the thermo¬ meter generally is from 90° to 120°, they are clothed from head to foot; and they cover the face up to the eyes with a black or coloured handkerchief. Those who inhabit the desert live by plundering the caravans from Morocco to Soudan, or by carrying salt to Timbuctoo, Kano, and even as far as Soccatoo. Lander, the servant of the late Cap¬ tain Clapperton, describes a troop of 500 camels laden with this article for the Soccatoo market. “ They were preceded,” he says, “ by a party of 20 Tuarick salt mer¬ chants, whose appearance was grand and imposing. They entered at full trot, riding on handsome camels, some of them red and white, and others black and white. All the party were dressed exactly alike. They wore black cotton tobes and trousers, and white caps with black tur¬ bans, which hid every part of the face but the nose and eyes. In their right hand they held a long and highly polished spear, whilst the left was occupied in holding their shields and retaining the reins of their camels. The shields were made of white leather, with a piece of silver in the centre. As they passed on, their spears glittering in the sun, and their whole bearing bold and warlike, they had a novel and singular effect, which delighted me.” They are, however, a very dirty people, and never wash themselves. Water, they say, was given to man to drink, and that it does not agree with the skin of a Tuarick, who always falls sick after much washing. They have partly embraced Mahometanism, and make use of water to perform their ablutions. They are exceed¬ ingly superstitious; and their whole clothing, spears, swords and muskets, if they have them, are covered over with charms. Tibboos. The Tibboos are apparently of a less pure race than the Tuaricks, being much more slender in their shape, having softer features, of a dark shining colour, nearly black, but with little or no appearance of the negro features. The women are described by Lyon as models of black beauties, full of vivacity, and tbnd of music and dancing. On the desert they frequent all the wells and wadeys, or little oases, with their sheep and goats. Neither the men nor the women cover their faces, but have the same bold indepeudent gait as the Tuaricks. The men are great traffickers in slaves to Bornou, Kanem, and Baghermi, which they carry to Fez- zan, Tripoli, and Egypt, in exchange for horses, which they sell at a high rate to the Bornouese. They are re¬ ported to be great thieves, laying wait to rob the caravans between Tripoli and Bornou, but never daring to attack them openly. Poor as they are, they are constantly ex¬ posed to the predatory excursions of the more fierce and warlike Tuaricks, who carry on their marauding expedi¬ tions to the very frontiers of Bornou and Soudan. The language of these several tribes of Berbers of the desert, as far as the few vocabularies extend, has been found to be very nearly the same. Moors. The Moors are numerously spread over that northern belt of Africa which is known, as we have already said, by the name of the Barbary States. They are a handsome race of men, resembling in their stature and features the best formed Europeans or western Asiatics, but of a darker com¬ plexion. They are more robust than the Arabs, their features more full; but they speak a dialect of the Arabic, abounding in expressions, however, that are peculiar to themselves. They are supposed to be the descendants of the ancient Mauritanians, from whom they derive their I C A. name, mixed perhaps with the Numidians, and subsequent- , ly the Arabs ; and as Sallust says that the Numidians and^ v Mauritanians were originally descended from an Asiatic colony composed of Armenians, Medes, and Persians, a comparison of the Moorish with these languages might prove interesting to the philologist. The Moors are de¬ scribed as a cruel, revengeful, and blood-thirsty race. They abound most in Morocco and Tripoli. The emperor of the former state was of the race of Moors that conquer¬ ed Spain, but since 1547- the posterity of Mahomet has sat on the throne; but the pasha of the latter state is of the Moorish race. The reigning family of both the one and the other, have been guilty of such atrocious and cold-blooded acts as make human nature shudder. The present pasha of Tripoli shot his own brother in cold blood, while he was sitting and conversing with his mother on an ottoman; and two years ago, his second son, Sidi Hamet, who is to succeed to the throne, the eldest being in exile, deliberately drew a pistol and shot his wife, a beautiful Georgian, just after her confinement, for having accused him of infidelity with two of her slaves. The Moors are temperate in their diet, and simple in their dress; but the women of Tunis, Tripoli, and Algiers wear splendid apparel, and deck themselves all over with gold, silver, and ornaments of precious stones. In the towns the Moors are merchants, and in the country the la¬ bours of the field are chiefly in their hands. On the borders of the desert, particularly in the Morocco dominions, they are found in considerable numbers, living, like the Arabs, in tents, and subsisting on dates, millet, and Indian corn, in the most frugal and abstemious manner. Here they practise the art of weaving, and of preparing what is known by us as Morocco leather. They dye skins and cotton cloth of different colours; they manufacture swords, and decorate their scabbards with plates of gold and silver; make stirrups and bridle-bits of single pieces of metal; work gold rings, chains, bracelets, and all other decorative ornaments, with great taste and skill; and are, in short, an ingenious people. The Arabs are spread over every known part of Africa, An and are just now in possession of the finest portions of Sou¬ dan. Mounted on their camels, or the swifter species of dromedary called moherey, they fly across the desert, and have planted the standard of their prophet from the shores of the Red Sea to Cape Negro, and from the Se¬ negal to Sofala. “ The conquest of Africa,” says Gibbon, “ from the Nile to the Atlantic Ocean, was first attempt¬ ed by the arms of the Caliph Othman. The pious design was approved by the companions of Mahomet and the chiefs of the tribes; and 20,000 Arabs marched from Medina with the gifts and the blessing of the commander of the faithful.” This event took place in the year of Christ 647. These conquests, however, were suspended, and about forty years afterwards the complete subjugation of this unfortunate country was reserved for Ackbah, whose career, as we are told, but not his zeal, was checked by the prospect of a boundless ocean. “ He spurred his horse,” says the Roman historian, “ into the waves, and raising his eyes to heaven, exclaimed, with the voice of a fanatic, ‘ Great God ! if my course were not stopped by this sea, I would still go on to the unknown kingdoms of the west, preaching the unity of thy holy name, and put¬ ting to the sword the rebellious nations who worship any other gods than thee.’ ” Gibbon had no dislike to an ori¬ ental hyperbole, and the one just quoted is made up from two French interpreters of Novaire’s Encyclopedia. The Greek colonists were expelled the country, but it was some time before the Moors consented to receive the laws, the religion, and the language of the Arabs. It is the custom to speak of the conquest of Spam by the Moors; but the motley crew which passed the strait, from Ceuta and Tangier, consisted of a far greater pro¬ portion of Arabs than of Moors. The true unmixed Arabs, or those who call themselves Shirifs, the descendants of the family of Mahomet, are easily distinguished from the Bedouins and the numerous tribes who have freely mingled with the people among whom they have planted themselves. The true Arab has a more lively and expressive physiognomy; a com¬ plexion more approaching to the olive colour; a small, dark, sparkling eye, deeply sunk in the head; an angular face; a short pointed beard; hair strong and black; a mouth but half-closed, discovering his teeth ; and a form of body more adapted for agility than strength. Those who dwell near the towns are cultivators of the soil, but the greater number lead a wandering pastoral life; and though capa¬ ble of the greatest exertion, and patient of hunger and fatigue, they are nearly as fond of an indolent inactive life as the negroes. The Arab women are almost univer¬ sally ill-featured, and when a little advanced in years are horribly ugly; notwithstanding which they exercise a considerable degree of influence over the men. rks It might have been supposed that the Moors and Arabs, who had driven the Greek and Roman colonists out of Africa, and who had succeeded in conquering Spain, when driven back out of the latter, would have been able to maintain their government in the former country ; but this unfortunate portion of Africa was doom.- ed to endure the more galling yoke of Turkish ferocity, nurtured by fanaticism and ignorance. A handful of Turkish adventurers succeeded in establishing their do¬ minion on the Barbary coast, and, by the payment of an annual tribute to the Ottoman Porte, have ever since continued their barbarous rule, by means of a few Turkish troops, over the more docile and industrious Moors and Arabs. The Turks are an ignorant, bigoted, and indolent race. They will lounge whole days, lying at full length on the flat roofs of their houses, or on the ground in the pub¬ lic places, or in frequenting the baths, or smoking opium and drinking coffee in the houses where these ingredients are sold ; but they are very rarely found to submit to any kind of labour. In Africa, indeed, they are almost exclu¬ sively employed in the military service. The most en¬ lightened Turkish ruler in Africa is Mahomed Ali Pasha of Egypt, but he has yet done as little as any of the rest to meliorate the condition of his subjects. Aiming at in¬ dependence, since the fatal blow recently given to the Ottoman dominion, and being free from the fanaticism of Islam, there is some hope, by the ardour with which he is adopting European arts and habits, that he may live to regenerate the fertile country over which he presides. ts' The Copts are very generally supposed to be the de¬ scendants of the ancient Egyptians, mingled with the Persians who are said to have been left by Cambyses, and with the Greeks carried thither by Alexander and the Ptolemies, the Romans under the eastern empire, and most, probably with the Arabs, more particularly those who inhabit Upper Egypt and Nubia. Their complexion js somewhat darker than that of the Arabs, their fore¬ heads flat, and their hair partakes rather of a soft and woolly character; their noses are short, but not flat; mouths wide, and lips thick; the eyes are large, and bent upwards in an angle like those of the Mongols; and their cheek-bones also are high, and their beards thin; and enon says there is no grace or symmetry in their shape, and that their bandy-legs and long flat toes are ill adapt- e ..;or agdity. Their original language, which they have 8 ul preserved, is a relic of the ancient Egyptian, mixed vol. ii. with some Arabic and Greek words. The Coptic alpha- Africa, bet, though evidently modelled on the Greek, contains some characters belonging to the ancient writing of the Egyptians; and the knowledge of this language has greatly facilitated the alphabet, which Champollon by years of application has extended a little, and but a little, beyond the attempts originally instituted by De Sacy and Dr Young, and of which he has availed himself, without the decency of acknowledging the obligation, as he ought to have done. The Copts are Christians, and addicted to trade and business; a habitude which affords them generally employment under the ignorant and in¬ dolent Turks. The Nubians are a mixed race between Arabs and Nubians. Ethiopians. The Barabras or Berbers, though somewhat similar to those already mentioned, are supposed to be a different people, or at least to have a greater intermixture with the Arab: their language also is different, as far as the vocabularies have been compared. Like the Arabs, they are so remarkably spare in their persons, as to have apparently almost neither fat nor muscle. Their skin is shining, and in colour not unlike bronze. “ Their hollow eyes sparkle under an uncommonly projecting eye-brow ; their nostrils are large, the nose sharp; the mouth wide, but the lips thin ; the hair of the head and beard is thin, and in small tufts. They become wrinkled at an early age, but are always lively and nimble ; they only betray their age by the whiteness of their beards. Their phy¬ siognomy is cheerful, and their dispositions lively and good-humoured. They dress in a piece of white or blue woollen cloth ; earn very little by their labour, subsist on next to nothing, and are always attached and faithful to their masters.’’ {Malte-Brun.) These people are found from Darfoor to Sennaar, and they are described by Burckhardt, at least such of them as dwelt at Berber and Shendi, to be a most debauched and drunken set,—men and women equally immoral and abandoned. The next class of Nubians are the Ababdes, who inhabit Ababde the deserts to the east of the Nile. They are Arabs, but Arabs, differ in customs, language, and dress, from the Arabs in Egypt. They are nearly black, but have Asiatic features ; live in tents, use little clothing, possess sheep, horses, and cattle ; but what they take most pride in is a species of camel, smaller and more active than the common kind, which they call aguine. They are Mahometans. Burck¬ hardt says they have for ages preserved the purity of their race, and will not permit their women to intermarry with the Nubians. “ They pride themselves, and justly,” says this intelligent traveller, “ in the beauty of their girlsand he describes them as an honest and hospitable people. The Nubians to the west of the Nile are descendants, in all probability, of the Nubae or Ethiopians of Ptolemy. They are a gentle kind of negroes, with small features, flat noses, and woolly hair. They are idolaters, and, ac¬ cording to Bruce, worship the new moon. They use cir¬ cumcision, but feed pigs, and eat pork without any scru¬ ple. They are found in this neighbourhood, and the whole way between the Nile and the great desert; and as far down as Bornou are found a great number of different tribes of Arabs, mixed more or less with the original native blacks of Africa, of many of which Burckhardt has given the best account probably that is extant, from his intimate knowledge of the language and history of the Arabians. Abyssinia is the country of the ancient Ethiopians. Abyssi- The inhabitants, however, are, strictly speaking, notnians. black, but their complexion is rather peculiar to them¬ selves, which Mr Bruce compares to the colour of pale ink; or, as may be inferred, a sort of iron-grey. Many, 2 F 226 A F El Africa, however, are described as of an olive brown, somewhat re- sembling bronze. And although in their well-shaped forms, their regular features, and their long hair, they ap¬ proach to the European, there may still be discovered in their features some faint traits of the negro. The Gheez language, in which the books of the Abyssinians are writ¬ ten, is considered to be a dialect of the Arabic; and the Amharic, which is the spoken language, and in use at court, though full of Arabic roots, is of a peculiar con¬ struction. It is concluded, therefore, that whatever the original race may have been, it has received a mixture of Arab blood; and the maritime parts, most probably, at some period or other, have been peopled by an Arab co¬ lony. They have, however, successfully resisted Islam- ism; but their Christianity is mixed with some of the Jewish rituals, and admits circumcision in both sexes as a harmless practice. The Troglodytes, who inhabit the country of Habesh, which extends along the Arabian Gulf, or Red Sea, seem to have changed little of the manners and customs ascribed to them by the ancients. The hol¬ lows of the rocks were, and still are, their dwellings; they subsist by fishing, and breeding a few sheep and goats; they speak the Gheez language, and are in all probability a branch of the original Abyssinians. CafTYes or Along the whole range of the eastern coast of Africa, Kafirs. from Cape Guardafui to within 500 miles of the Cape of Good Hope, are a race of people more or less black, ge¬ nerally of a deep bronze colour, large in stature, of a bold and independent gait, of fine forms, and strongly built, having the head shaped like the most perfect of Euro¬ peans, the nose a little arched, the lips somewhat thick¬ ened, the hair frizzled, but wiry rather than woolly, and, when suffered to grow long, hanging in spiral locks like so many cork-screws. They make u§e of different dialects of the same language, in all of which may be heard a mixture of Arabic words, more or less as they are nearer to or farther from the Strait of Babel- mandib. The Portuguese, when they had first doubled the Cape of Good Hope, and touched at the Arab settle¬ ments on the eastern coast, learned from the Mahometan settlers, that these people were called Caffres or Ka¬ firs, by which they meant only that they were infidels. Those tribes nearest to the colony of the Cape still bear the name. It does not appear that they anywhere ex¬ tend a great way into the interior, as the whole of the many thousand slaves that have lately been carried away from this coast of Africa by the French, the Portuguese, and the Imaum of Moscat, were negroes, the warlike Caffres having successfully repelled every attempt of these infamous traders to reduce them to a state of sla¬ very. The tribe nearest to the Cape colony call them¬ selves Koussie. Beyond them are the Hamboonas, and at Port Natal the Zoolas. Those who inhabit the inte¬ rior to the north and north-west are the Boshuanas, the Barroloos, and the Wanketzens ; and thus, till we reach the Gallas, at the foot of the Abyssinian Mountains, each tribe has its own name, though they are evidently sprung from the same origin, a mixture of Arabs with the native black African. These several tribes subsist almost en¬ tirely by their herds of cattle, and a little millet (holcus), and a species of bitter gourd, these being almost the only plants they cultivate, at least to the southward. More northerly, the country, increasing in warmth of cli¬ mate and fertility, may probably afford them spontaneous products of nutriment. At Port Natal a lieutenant of the English navy has established a little colony, to which these people bring him large quantities of ivory, skins, bees-wax, and some other articles, which he purchases cheap, and sends to the Cape of Good Hope. I C A. In the southern angle of Africa, and confined within very narrow limits, is a race of men totally distinct from every other tribe of people on that continent, and, inH 5 some respects, from every known people in any part ofto! the globe. Where they originally came from, and how they happened to be hemmed in, and confined entirely to this remote corner of the earth, is a problem not likely to be ever satisfactorily solved. The only people to whom the Hottentot has been thought to bear a resemblance are the Chinese or Malays, or their original stock the Mon¬ gols. Like these people, they have the broad forehead the high cheek-bones, the oblique eye, the thin beard and the dull yellow tint of complexion, resembling the colour of a dried tobacco leaf; but there is a difference with regard to the hair, which grows in small tufts, harsh, and rather wiry, covering the scalp somewhat like the hard pellets of a shoe-brush. The women, too, have a peculiarity in their physical conformation, which, though occasionally to be met with in other nations, is not uni¬ versal, as among the Hottentots. Their constitutional “ bustles” sometimes grow to three times the size of those 1 artificial stuffings, with which our ladies are now (1829) disfiguring themselves. Even the females of the diminu¬ tive Bosjesmen Hottentots, who frequently perish of hun¬ ger in the barren mountains, and are reduced to skeletons, have the same protuberances as the Hottentots of the plains. It is not known even whence the name of Hottentot pro¬ ceeds, as it is none of their own. It has been conjectured that hot and tot frequently occurring in their singular lan¬ guage, in which the monosyllables are enunciated with a palatic clacking with the tongue, like that of a hen, may have given rise to the name, and that the early Dutch settlers named them hot-en-tot. They call themselves qui-quoe, pronounced with a clack. They are a lively, cheerful, good-humoured people, and by no means want¬ ing in talent; but they have met with nothing but harsh treatment since their first connection with Europeans. Neither Bartholomew Diaz, who first discovered, nor Vasco de Gama, who first doubled, the Cape of Good Hope, nor any of the subsequent Portuguese navigators, down to 1509, had much communication with the natives of this southern angle of Africa; but in the year above mention¬ ed, Francisco d’Almeyda, viceroy of India, having Landed, on his return, at Saldanha (now Table) Bay, was killed, with about twenty of his people, in a scuffle with the na¬ tives. To avenge his death, a Portuguese captain, about three years afterwards, is said to have landed a piece of ordnance loaded with grape shot, as a pretepded present to the Hottentots. Tw o ropes were attached to this fatal engine ; the Hottentots poured down in swarms. Men, women, and children flocked round the deadly machine, as the Trojans did round the wooden horse, u funmque manu contingere gaudent” The brutal Portuguese fired off the piece, and viewed with savage delight the mangled carcasses of the deluded people. The Dutch effected their ruin by gratifying their propensity for brandy and tobacco, at the expense of their herds of cattle, on which they sub¬ sisted. Under the British sway they have received pro¬ tection, and shown themselves not unworthy of it. They now possess property, and enjoy it in security. One of the most beautiful villages, and the neatest and best culti¬ vated gardens, belong to a large community of Hot¬ tentots, under the instruction and guidance of a few Mo¬ ravian missionaries. Africa possesses in abundance all the larger kinds ofQt quadrupeds that are found on other continents, with manyPe that are peculiar to itself; as, for instance, the giraffe or Camelopardalis, the hippopotamus, the zebra, the quacha, the gnoo, and some other species of the antelope tribe, AFRICA. 227 of the last of which there are about twenty, and the ► Afi,W two-horned rhinoceros, of which tl^ere are at least two ^ varieties. Of the minor quadrupeds, there are also many species unknown to other countries, and many yet, no doubt, remain to be discovered. The ancients had a strange no¬ tion, from the extraordinary nature of the Camelopardalis, the ostrich, and some others, that newly-created species were constantly springing up in Africa, which is thus ac¬ counted for by Pliny: “ Africa hcec maxime special, inopia aquarum ad paucos amnes congregantibus se feris. Idea multformes ibi animalium partus, varie fceminis cujusque generis mares awl vi aut voluptate miscente. Unde etiam vulgare Grcecice dictum—semper aliquid novi Africam afferre.” A brief notice of some of the more remarkable animals will suffice, in the general view we are now taking of the continent of Africa. Ip, ( That extraordinary animal, named the Camelopardalis jji', or giraffe, is found in all the dry regions of Africa, between the sources of the Senegal and Dongola; but it is doubt¬ ful whether it is ever met with in the rich soil of Soudan. There is reason to believe, however, that it is common in most parts of South Africa, as far down as the Orange River, along the northern banks of which they are found in great numbers; but none has been known to cross this river. For a long time the existence of such an animal was considered to be doubtful, though various writers have mentioned their being exhibited at Rome ; but it is now familiar enough, particularly since the pasha of Tripoli sent over two living species, one for his Majesty, and the other for the king of France. In its native country it browses on trees, particularly on a species of mimosa; but when domesticated, which it soon becomes, it will eat any kind of vegetable food. On the passage of the two in question from Tripoli, they were fed chiefly on cow’s milk. They are mild and inoffensive animals. ’he iip- This singular and unwieldy animal, we believe, ispecu- opoU liar to Africa, in almost all the large rivers of which it is found in considerable numbers, though it has been sup¬ posed to exist in the rivers of Sumatra. This is not very probable, as it would not be easily explained how it came into this insulated situation, seeing that it has no existence in India or China, or in any other of the large islands of the Indian Ocean. This amphibious creature seems to derive its chief sustenance from the land, though its dwelling is mostly in the water, from which it never proceeds to any great distance. It browses on the near¬ est shrubs, and feeds on the reeds of the marshes. “ He lieth,” we are told in the book of Job, “ under the shady trees, in the covert of the reed and fens ; the shady trees cover him with their shadow, the willows of the brook compass him about.” In their track, which is easily dis¬ covered by two deep furrows like the ruts of waggon- wheels, the negroes make a deep pit carefully covered oyer, into which if he once fall, there is no possibility of his ever getting out. The Caffres and Hottentots, how¬ ever, say that he has learnt to be too cunning to fall into the trap; and their mode of taking him is to watch by eight, and to wound him with their darts or spears in the tendons of the knee-joint, which lames him so much that they easily dispatch him with their numerous hassagais. Ihe little Bosjesmen Hottentots, however, continue to take them in pits. Mr Barrow says, that in the Orange River his party shot no less than four in one day, out of one of which a perfectly formed foetus was taken, wanting only the teeth and tusks. It was only seven inches long, while the weight of the parent was estimated to be from three to four thousand pounds. i f 1 ns curwus animal, of the asinine tribe, is singular h'om having its body striped in every part, from the tip of the nose to the end of the tail; but its head is large, Africa, its ears long, and it is without beauty of form in any part of its body. It is difficult, if not impossible to tame it, when taken at full growth, being vicious in the highest de¬ gree. An Irishman belonging to a dragoon regiment per¬ sisted in mounting a half-tamed female zebra belonging to the Landrost of Zwellendam. She kicked, plunged, and threw herself down, to no purpose ; the man kept his seat. She then threw herself from a high bank into a hole in the river; the dragoon was thrown, but still kept hold of the bridle, and she dragged him to the shore, when turning quickly round, and putting her head close to his face, she completely bit off his ear. This animal is also peculiar to Africa, and was long The considered as the female zebra. It is, however, a distinct Quacha. species, less striped, but much more robust, and better shaped, than the zebra, and not difficult to domesticate. A pair of these animals were to be seen not long ago draw¬ ing a light carriage in Hyde Park. The late Lord Mor¬ ton had a stallion that covered an Arabian mare, which produced a handsome horse, partaking much of the form, and having the stripes of the quacha. But the most re¬ markable circumstance is, that the same mare afterwards produced two foals in succession, on which the stripes were very visible, though she had been removed from the quacha to another part of the country, and had never seen him but at the time above alluded to. This fact has been attested by Sir Everard Home, who examined the two foals. This animal, of the antelope genus, for so it has been The Gnoo. classified by naturalists, is a most extraordinary creature. It has been described as partaking in its form of the horse, the ox, the stag, and the antelope; the shoulders, body, thighs, and mane, being equine; the head completely bo¬ vine ; the tail partly of the one and partly of the other, exactly resembling that of the quacha; the legs and feet slender and elegant like those of the stag; and lastly, it has the subocular sinus, which is supposed to be the dis¬ tinguishing characteristic of the antelope tribe. In the Systerna Naturce of Linnaeus, it is described, by Sparrman, among the antelopes, and mentioned also a second time as a variety of the bos Coffer, under the description of ele- gans et parvus Africanus bos. It is so fierce, and so full of gambols, that the Dutch boors of the Cape have named it the wilde beest. It possesses in an eminent degree strength, swiftness, a nice nose, and a quick sight. Its motions are free, varied, and always elegant: whole herds of them are seen together in the plains bordering the Orange River. Truter and Somerville procured in the Boshuana country a much larger species called the kokoon, having a long flowing black mane, not erect and trimmed, as it appears to be in the common gnoo. The common two-horned rhinoceros of Africa is alto- The Rhi- gether different from that of India in its figure and cha- noceros. racter. The skin may be called smooth when compared with the folds that are so remarkable in the Indian species, which is covered as it were with a hide of mail. The eyes are very low in the head, almost at the root of the nose, and close under the upper horn, and so minute, that one would be apt to conclude them of little use to so en¬ ormous an animal; but by being placed in a sort of pro¬ jecting socket, nature has compensated this apparent want by giving them a greater range, allowing them, with¬ out moving the head, to sweep round a portion of the horizon equal perhaps to 260 degrees. The variety found near the mouth of the Orange River is called the white rhinoceros, being much larger than the other, having its hide remarkably thin, and of a pale carnation colour, all of which, however, may be the effects of age. Another variety was met with at a considerable distance to the 228 AFRICA. or Eland. Africa, north-east of the Cape colony by the missionary Camp- bell, having the longer horn almost perfectly straight and of an unusual length, while the lesser one was smaller in proportion. And Truter and Somerville, in the Boshu- ana country, met with a very large species, with the two horns nearly of the same length, which the natives called the jeckloo. This large animal, of one species or another, is found in all the woods of Africa, from Soudan to the Cape of Good Hope. The Oreas Of this family of animals Africa contains more species than are to be found in all the rest of the world, and of all sizes, from the large oreas, which the Dutch call eland, to the small pigmy antelope; but then Africa is supposed not to possess a single species of the Cervus or deer tribe in a state of nature. The oreas is the finest species of this numerous genus; it has a large dewlap, and other characteristics of the bovine genus. The male has been known to measure the enormous length of ten feet and a half, by six feet and a half in height. The flesh resembles that of beef, on which account the boors hunt them, and salt the flesh for winter provision; and so easily are these animals overtaken, that in all probability the eland has ere this disappeared from the colony. This is another large species, also partaking of the ox, and hunted down for the sake of its carcass. Like the for¬ mer, this is also a mild and patient animal; its size about seven feet long by five high. Like the eland, too, it is a gregarious animal; but being easily hunted down, both species will probably disappear altogether. The Strep- This is a noble animal, but somewhat inferior in size to siceros or the bubalus. It is the striped antelope of Pennant, and is remarkable for its long spiral horns, which are commonly to be met with in almost every museum of natural history. A black mane adorns the neck of the male, and along the spine is a ridge of white hairs. The female has none of these, nor any horns. This is one of the most elegant, and by far the most nu¬ merous, of all the species of antelope that frequent South¬ ern Africa. They have been known to assemble in herds of thousands, particularly when about to migrate towards the north. The leaps that this creature is enabled to take are quite astonishing, being from fifteen to twenty-five feet. No dog is able to approach them, except when jammed together like a flock of sheep, which sometimes happens in making their way through a narrow pass. The other antelope species that are met with in the colony of the Cape, are (taken in the order of their size), the gems-bok; (A. Oryx of Syst. Nat. and Passan of Buffon); the blau-bok (A Leucophcea) \ bonte-bok (A. Scripta); the steen-bok; the bosch-bok; the klip-springer; the greis-bok; the duyker; the reit-bok; the Orabie ; and the Pygmcea, the smallest perhaps of hoofed quadrupeds, with the exception of the little Indian musk-deer. Many other species of this extensive genus are no doubt to be found in other parts of Africa. Two new ones were seen by Messrs Truter and Daniell in the Boshuana country, the one named the palla, resembling the spring-bok in shape and horns, but larger; and the tak-heize, or wild crea¬ ture, so named from its ferocity, though apparently partak¬ ing of the cow and the antelope. Two or three others, apparently new, were also seen by Denham and Clapper- ton in Soudan. The numbers that formerly frequented the Cape have considerably diminished since the forma¬ tion of the new settlements to the eastward: even previ¬ ously to this, where the Caffres had possession of the plains of the Zeure-feld, their mode of hunting was not only most destructive to the several kinds of game, but calcu¬ lated to drive them away beyond the limits of the colony. A party, consisting of several hundreds, men, women, and The Buba. lus or Ha- sJebeest. Koodo. The Py. gargus or Spring¬ bok. children, formed a circle round the plain on which they discovered a herd of antelopes: they then marched to-^ wards the centre, narrowing the diameter till the obiects of their pursuit were completely fenced in. The ante¬ lope tribe, more particularly the spring-bok, follow their leaders like sheep. An opening is made in the circle through which all endeavour to rush, and while impeding each other, the men with their hassagais get in among them and make a dreadful slaughter. This huge animal is found in all the wooded parts ofTb Africa, from the southern boundary of the great desert pha to the Cape of Good Hope, on the eastern coast of which they are still very numerous. Gigantic as it is, the ele¬ phant is a harmless animal in comparison with the lion the leopard, wolves, and hyenas; but if irritated, he never fails to seek revenge. The Caffres and the Negroes usual- ly take them in pits, at the bottom of which are fixed sharp stakes. The African elephant is of a less size than those of India, Pegu, Siam, Cochin-China, and Ceylon, rarely averaging more than nine feet; whereas in the coun¬ tries above mentioned they attain the height of eleven feet. Dr Lichtenstein was assured by experienced hun¬ ters, and he was silly enough to believe them, that in the forests of Tsitsikamma, in Southern Africa, there are ele¬ phants eighteen feet high, that run in troops of 500 to¬ gether. Major Denham also says, that on the margin of the lake Tsad may sometimes be seen elephants of sixteen feet high, in troops of 400. It does not appear, however, that he ever had any opportunity of measuring one, other¬ wise he would have corrected his mistake as to size. This animal is the bos Coffer of the Systerna Natura, The If. and is probably the most fierce and powerful of the bo-bo¬ vine tribe. Its height is about that of a common-sized ox, but it is nearly twice its bulk. Its horns are twelve or thir¬ teen inches broad at the base, separated only by a narrow channel, which fills up with age, and gives to the animal a forehead of solid horn, hard as rock. The lion is said some¬ times to measure his strength with the buffalo, but his at¬ tack is, as usual, by stratagem. Couching till his prey is within his reach, he springs upon his back, fixes his fangs in his throat, strikes his paw in his face, and pins him by the horns down to the ground. The African lion is the noblest animal of his race. The! None of the Asiatic lions are to be compared with him for size, strength, or beauty. Indeed it is a remarkable fact, that all the animals in Africa are superior to those of the same species in other countries, with the exception perhaps of the elephant, which, as we have said, is much smaller than those of India, Siam, and Cochin-China, and also of Ceylon. The habits of the lion differ little from those of the rest of the feline tribe. He seldom attacks openly, and not at all except when pressed by hunger. Much of his life is supposed to be passed in sleep, from which he is roused only by hunger. He then watches in ambush till an opportunity offers for pouncing on his prey; but if nothing present itself near his den, he walks out leisurely; and in the exact manner of a cat when she ad¬ vances towards a mouse or bird, does the kingly mon¬ ster approach a flock of antelopes or sheep, till he may be able to pounce upon his victim. The Hottentots say, and the Dutch boors of the Cape confirm it, that if a lion should get near a flock of sheep guarded by one of these people, he will invariably prefer the biped to the quad¬ ruped, and in doing so he shows his judgment; for, to un¬ case a sheep of its woolly covering would require some labour, which his indolent habits prompt him to avoid. The naked Hottentot requires no preparation; besides which, he is generally well basted with grease. The lion is found in every part of Africa. The striped Bengal tiger is peculiar to India and some rvMother parts of Asia; but in Africa there are various species of the tiger family, less powerful, but not less fero¬ cious than that of Bengal. Leopards are numerous and very fierce; and a smaller kind, known as the tiger-cat, not less so; and all of them, if hard pressed, will turn round and spring upon their pursuers. u p , The native dogs are of two kinds, one large, resembling the common wolf and another small, not unlike the fox or common jackal. There are besides two species of ravenous wolves, which commit great depredations among the cattle ; two species of jackal; and two of hyenas, one striped, the other a dark brown colour. These disgusting animals, in the early periods of the Cape settlements, were numerous in the caves of the Table Mountain, and used to prowl the streets of the town at night. Kolbe relates a story of a drunken trumpeter, while asleep in the street, being seized and dragged along by one of these powerful animals. The man awaking, and without exactly knowing what was going on, got his trumpet to his mouth and blew a blast, which so terrified the ravenous beast, that he im¬ mediately let loose his prey, and ran off at full speed, bor That curious animal, the sus Ethiopica, is found in all iriru: the woods, whose hooked tusks, curved upwards, have !*■ puzzled philosophers so much in endeavouring to explain their utility: they are certainly not intended, as an in¬ genious Frenchman suggested, to hang up the animal’s head on a branch while it sleeps. The earth hog of the Dutch is the myrmecophaga, or ant-eater. The hystrix icristata, or crested porcupine, is also common; and al¬ most every species of the genus viverra is abundant¬ ly found in all parts of Africa. Baboons and monkeys of all sizes and varieties are most abundant in the woods of the tropical regions; but the cynocephalus, or black baboon, is almost the only one that frequents the more temperate climates. Lizards abound in all the sandy deserts, and tw6 or three species of the cameleon; and the crocodile or alligator is found in all the larger rivers, to the great terror of the negroes. In fact, they are as dangerous to man when in the water as the sharks are. The singular attack made by one of these animals on Isaaco, who accompanied Mungo Bark, would not be credited on less authority than that of the unfortunate traveller himself, ffts d It is almost unnecessary to observe, that in such a cli- ^eS: mate as Africa, noxious insects and reptiles of almost every kind abound : scorpions, scolopendras, enormous spiders, snakes, and other venomous creatures. But the Africans suffer less from any of these than from two other objects, which, though individually harmless, are, when in swarms, I the greatest scourge that can be inflicted on a country. These are the termites or white ants, and the grylli or lo- k u custs. These ants, small as they are, construct their habi¬ tations of clay of an enormous size. Clapper ton met with some of these in his last journey, rising to the height of ten or twelve feet, and having the appearance of so many gothic cathedrals in miniature. In the extra-tropical parts they rarely exceed four or five feet. This destructive creature devours every thing in the shape of wood, leather, cloth, &c. that falls in its way ; and they march together in such swarms, that the devastation they commit is al¬ most incredible. One of the Portuguese missionaries to Congo relates, that an army of these insects not only drove him out of his house, but ate the whole of it except the "alls; and another says, that having tied up a cow in an outhouse, he found in the morning nothing left of the ani- mal but the skeleton. Stories equally wonderful are told 0 r!1’8 Pernicious insect in India. ^ocusts are still more destructive, for they some- 1 tlrnes lay waste a whole country. They are gregarious, and whenever an army of these insects is on its march, Africa, not a blade of grass or leaf of tree or shrub escapes their voracious appetite; and the tract of country over which they have passed appears as if it had been swept with a broom. In a few hours a whole field of corn is totally consumed. No remedy has yet been discovered to stay this afflicting scourge. The smoke of green wood seems to annoy them; but if they rise from one place, it is only to alight again in the immediate vicinity. It has been stated by various travellers of undoubted veracity, that, when on the wing, they form so numerous and dense a phalanx, as to obscure the face of the sun like a black cloud. Africa contains the hugest of birds, the ostrich, as well Birds, as the largest of quadrupeds; and it has specimens of the feathered race of all gradations of size, and brilliant plum¬ age, down to the beautiful little certhia or creeper. The con¬ dor vulture is not uncommon; the percnopterus or Egyp¬ tian vulture, and the sociable vulture, are most abundant; and all that Pliny has related of this bird, as to its sagacity in discovering dead carcasses, seems to be perfectly correct. We are told, that if an animal should die in the very midst of the dreary desert, in the course of a few minutes there will be seen, high in the zenith, a number of minute objects descending in regular gyrations, and increasing in size at every revolution, and these on their approach to the earth are discovered to be vultures. Thus descending even in the presence of man, they will at once pounce on the prey, which they devour with such greediness as frequent¬ ly to be unable to rise from the ground. The serpentarius, or snake-eater, called by the Dutch the secretary bird (from some quill-feathers growing out of the head), is the declared enemy of snakes, which it attacks wherever they are met with, and feeds its young with them. Eagles, kites, and crows are abundant; and guinea fowls, bus¬ tards of an enormous size, grouse, partridges, and quails, much more so. The Numidian, the virgin, and Balearic cranes, the rose-coloured flamingo, the solitary pelican, and a great variety of water-fowl, frequent the lakes and rivers of every part of Africa except the sandy desert. In the equinoctial regions are parrots and paroquets innumer¬ able, and birds of the most beautiful plumage, but with¬ out those sweet notes with which our more modestly clothed warblers are gifted. Nothing can exceed in ele¬ gance and brilliancy, on a sunny day, the numerous tribes of certhias, which, perched on the petals of the vase¬ shaped corollas of the protea mellifera, may be seen in great numbers, sipping out the honey with their long scimitar-shaped beaks. It is almost unnecessary to say, that on both coasts of Fishes. Africa, within the tropics, sharks are most abundant. Whole shoals of them may be seen in the Bight of Benin and that neighbourhood, following the slave ships in parti¬ cular, from which no day occurs without some unfortunate victim being launched overboard. On the southern coasts, on both sides of the continent, both the black and sperma¬ ceti whales are plentiful. The edible fish are various, and some of them, of the perch genus in particular, are very good. Having thus taken a very general view of the face of the Distribu- country, its productions and varied inhabitants, the next tion of step will be to give a brief account of their particular dis- Africans, tribution and condition, state of society, habits of industry, ^c' and other particulars, as far as our limits will allow; com¬ mencing with Egypt and Abyssinia, continuing down the eastern coast to the Cape of Good Hope, thence to the Straits of Gibraltar, and returning along the Mediter¬ ranean to the Isthmus of Suez, whence we set out: after this to take a condensed view of the interior of Northern 230 AFRICA. Africa Egypt. • Africa, as far as the late geographical discoveries will with ^ certainty admit. The government of Egypt, under its present ruler Ma¬ homed Ali, is unquestionably the most civilized of any in Northern Africa. Perhaps also it is the most populous, and, with its late conquests, embraces a larger extent of territory, comprehending Nubia, Dongola, Sennaar, and, nominally at least, Cordofan, and Darfoor. The pasha nominally holds under the Ottoman Porte; and his confidential officers, and those of the army, were mostly Turks, until the late unfortunate campaign with Russia, since which he is said to have discharged every Turk from his army. There are however many Arabs, particularly in the upper parts of Egypt, and in the deserts on each side of the Nile. The Copts are mostly in Lower Egypt, and are many of them employed as writers and factors. The great mass of the population are the fel¬ lahs or cultivators of the land, a mixed race of Moors, Arabs, Copts, and Negroes. The chief city is Cairo, which has often been described, and the pi'incipal port Alexan¬ dria. It is said, that from 20,000 to 40,000 pilgrims, from the Barbary States and other parts of Africa, on their way to Mecca, used annually to pitch their tents under the walls of Cairo, where they were supplied with provi¬ sions for their future journey, on which the pasha took care to levy a contribution; but there is reason to sup¬ pose that these pilgrimages have received their death¬ blow by the late events. From Cairo", the two chains of hills which bound the valley of the Nile begin to diverge, the one turning east to Suez, the other north-west to the Mediterranean. The valley they inclose is the delta of the seven-mouthed Nile, all now closed up except two ; the one emptying itself into the Mediterranean at Rosetta, the other at Damietta. This great triangular plain owes its fertility to the annual overflowing of the Nile, which is of so extraordinary a na¬ ture, that without manure or lying fallow, it has continued to yield an annual crop for several thousand years. The mud which the Nile deposits, on being analyzed by the French, was found to contain nearly one-half of pure argil¬ laceous earth, about one-fourth of carbonate of lime, the remaining fourth carbonate of magnesia, oxide of iron, and water. All kinds of grain and vegetables grow on the delta with the greatest luxuriance. Cotton, flax, indigo, carthemum, tobacco, beans in great variety, and cucurbi- taceous vegetables, are the most common products of Lower Egypt. In Upper Egypt, Nubia, Dongola, and Sennaar, the dourrha (hole us) is the common food of the people. The date-palm is seen in groves of thousands together, and gives a striking character to the country. Citrons, lemons, oranges, pomegranates, bananas, figs, the carob, jujube, and olives, and the laurus Persia, are abundant. The cassia fistula and the mulberry are also com¬ mon. The few trees not of much use are chiefly confined to accacias or mimosas, sycamores and willows. They have plenty of good horses; those from Dongola being of an excellent breed. They have also fine asses and mules, camels and buffaloes, sheep and goats. Poultry is abundant; and the factitious incubation of eggs, by means of artificial heat, is still practised. The Nile is not much celebrated for esculent fish; and the huge hippo¬ potamus and the crocodile are almost entirely banished from Egypt, particularly the former. The ibis, held sacred by the ancient Egyptians, is a species of curlew still extant; and the perenopterus vulture still acts as the scavenger of the towns and villages. The invasion by the French destroyed what little trade the port of Alexandria then possessed, which it has not yet recovered, though it is on the increase. Most travel¬ lers agree in the melancholy feelings, excited by the forlorn and neglected state of this once magnificent city, which abounded in temples, palaces, baths, and theatres, and which is said to have reckoned 300,000 freemen amone its population, when it first fell under the dominion of the Romans. On Mahomed Ali’s accession to the govern¬ ment, not more than about 100 vessels frequented the port: they are now at least 1000. The population may be reckoned about 20,000. Rosetta is a dark and dismal city, the upper parts of whose houses, like those in the old towns on the continent of Europe, overhang the ground stories, and almost meet at top ; but it is surrounded with date-trees, bananas, and sycamores. Damietta is sur- rounded by a swamp or morass, which is noted for the excellence of its rice. It is a dirty town, with a consi¬ derable population, among whom fevers, agues, and blind¬ ness, are the predominant diseases. The former of these cities contains about 20,000 inhabitants, and the latter about 40,000. The total population of Egypt, exclusive of the wandering Arab tribes, is reckoned at about 2,000,000; and these pastoral tribes may perhaps amount to about half a million more. The Greek war, in which the pasha was compelled to take a part, and the annual tribute he has been obliged to pay to the Ottoman Porte, have greatly embarrassed his finances. Before the battle of Navarin, he is said to have had 50 sail of ships of war, great and small, and from 30,000 to 40,000 regular troops! To recruit these, both the agriculturists and the merchants, chiefly Jews and Armenians, have been greatly oppressed by new and excessive contributions. The condition of all classes of the population, but more especially of the agriculturists, is as miserable as can well be imagined. It would appear indeed to have undergone no change for the better since the days of the Pharaohs; and in later times, whether under the yoke of the Persians, the Greeks, Romans, Arabians, Turks, Mamelukes, or French, this unfortunate country, as Niebuhr has justly observed, has enjoyed no interval of tranquillity and free¬ dom, but has constantly been oppressed and pillaged by the lieutenants of a distant lord; the sole object of both being that of extorting as large a revenue as possible from the hard hands of the peasants. In Nubia, the mass of the inhabitants who are named Barabras, or Berebers, or Berbers, are more independent than those below the cataracts of the Nile. They are found in Dongola and Sennaar, and along the western side of the Nile, residing among the Arabs and Negroes, and their mixed offspring, from whom however they are easily distinguished. They are stated to be a frugal, harmless, and honest people, subsisting chiefly on dates, dourrha, and a few leguminous plants. When Mr Legh visited Dehr, which he calls the capital of Nubia, the cachef was drunk. He had 300 armed negroes at his elbow, and at least 3000 in the district. These fellows, as Burck- hardt observes, are to be dreaded by travellers ; but there is nothing to fear from the Nubians, who are in general free from the vice of pilfering. This intelligent traveller makes a remark which is curious, that the size and figure of the Nubians were generally proportioned to the breadth of their cultivable soil, that is, in other words, to the quantity of food they had to subsist upon. The chief produce is dourrha, of which they make a kind of cake, not unlike the teff of the Abyssinians ; and they also brew a strong beer or spirit from it, called booza, which, it ap¬ pears, is known under the same name all over Soudan, and in which all classes were observed by Burckhardt to indulge to the greatest excess, as he advanced to the southward, more particularly at Berber and Shendi. Still farther south is Sennaar, which also submitted a frits, Al AFRICA. few years ago to the arms of the pasha of Egypt; but the m0untaineers to the southward and westward, between the rivers Azrek and Abiad, refused to acknowledge their new master. These mountaineers are described as a fine and handsome race of men, quite black, but with Arab features, which nearly resemble those of the inhabitants of Sennaar. They are called Bokki, and resemble in their dress very much the Indians of South America, being covered almost with beads, bracelets, and trinkets, made of pebbles, bones, and ivory. The men have helmets of iron, coats of mail made of leather, carry long lances, and a weapon resem¬ bling the ancient bills used by the yeomanry of England. A musket, which was new to them on the invasion of the Turks, they called a coward’s weapon, which destroy¬ ed life by an invisible stroke. An American gentleman, who accompanied the pasha’s army, describes the people from Assuan to Sennaar as differing in character and complexion as follows: Those of Succoot are less black than the Nubian and Dongolese; the latter are dirty, idle, and ferocious ; those of the third ,cataract are indolent, but honest and obliging. The Ber¬ bers are the most civilized; the people of Shendi and Halfeya are sullen, scowling, crafty, and ferocious ; while the peasants of Sennaar are a quiet and respectable peo¬ ple, but very much the reverse in the capital. They re¬ semble, he thinks, the Indians of America in possessing the general characteristics of courage and self-respect. That long strip of land interjacent between the Nile and the Red Sea, and from the Isthmus of Suez to the Strait of Babelmandib, an extent of 13 degrees of latitude, or 780 geographical miles, is a naked and arid desert of rock and sand, wholly destitute of water. A precipitous chain of mountains bounds the eastern shores of the Nile like an artificial wall; and the boundary next the Red Sea is in most places equally precipitous, affording very few, and these but indifferent, harbours. , This country seems to have no particular name, though it is sometimes called Habesh, by some Asiatic Egypt, and by others African Arabia. The latter might be the most proper, as it is chiefly inhabited by a few straggling Ababde Arabs, with their sheep and goats, and by some mixed Arabs, and Negroes, and Copts, as fishermen on the sea- coast. Bruce calls them Agazi or Gheez, which means shepherds; and they speak the Gheez language, which is a dialect of the Arabic. It was in this miserable country that the ancients placed the small race of men called the Troglodytes, from their dwellings being the caverns of the rocks; and it was here, too, that the ancients were supposed to have worked the emerald and the topaz mines, and which the present pasha of Egypt employed a frenchman of the name of Caillaud to explore and work. At Mount Zaborah, seven leagues from the Red Sea, and 45 to the southward of Cosseir, he gives a mar¬ vellous account of a mine into which he descended through difficult and winding passages, 400 feet under ground, and brought back a hexahedral prism of emerald. This mountain appears to be the Jebel Zumnid of Bruce, who “ saw in four days more granite, porphyry, marble, and jasper, than would build Rome, Athens, Corinth, Syra¬ cuse, Memphis, Alexandria, and half a dozen such cities.” Belzoni thought these mines, with their pits and shafts, nothing more than stone quarries. The pasha, however, nas so pleased with his emerald, that he gave Caillaud ~ camels, and 50 Ababde Arabs to take care of them, to load with the precious stones; but the whole party, men and beasts, had nearly perished for want of water. e brought back, however, to Cairo several pounds’ weight o green stones, which he called emeralds, but which were pi obably nothing more than beryl or aqua marina, which 231 did not answer the purpose of the pasha, and the search Africa, was discontinued. He talks of thousands of excavations, and traced the ruins of a Greek city of stone, 500 houses of which were still standing, in which were lamps, broken vases of earth and glass, and circular stones for grinding corn. The Arabs call it Sekket Bender el Kebyr. It was on this desert also that Ptolemy Philadelphus built the city of Berenice, which afterwards became the emporium of the eastern trade carried on by the Romans, and whose site is supposed to be near the port of Habesh. It was on this arid desert also that the ancient Ascetics, equally ignorant and uncivilized as the savage Troglodytes, had their cells; and it is said that the monasteries of St An¬ thony and St Paul are still inhabited by Coptic monks, who pretend to have power over the serpents and scor¬ pions, the demons, and the few prowling beasts of prey that infest the country, while they are unable to protect themselves from the depredations of the starving Arabs of the desert. Cosseir, and Suakim, and Massuah, are the principal ports on this barren coast of the Red Sea. The name of Habesh, or the mixed people, is given to Abyssinia, the Abyssinians by the Mahometans. Abyssinia is a moun¬ tainous country of considerable extent, divided into seve¬ ral kingdoms, or rather provinces, as Tigre, Wagora, Sa- men, Dembea, Gojam, Amhara, Damota, and some others. Whatever may have been the primitive race of Abyssinia, it is evident, from the two languages of the country, the Gheez and the Amharic, being dialects of the Arabic, that the present inhabitants are a mixed race of Arabs and some other, probably that of the Copts, with a little of na¬ tive African or negro blood also in their veins. They have a history which goe.s back to the celebrated queen of Sheba, who travelled to Judea to admire the magnificence of So¬ lomon, and is said to have brought back a living token of the effect which her charms produced on the Jewish king; and that his descendants continued to reign for 960 years after the birth of Christ. In the fourth century, the Christian religion was introduced into Abyssinia, and has continued ever since; but they retain the Jewish rite of circumcision. The city of Axum, in Tigre, is the ancient residence of the Abyssinian monarchs, who still go thither to be crowned. The obelisk described by the early Portuguese travellers, of a single block of granite, was seen by Salt, who states it to be 80 feet high. There are many ruins of temples, and palaces, and monuments, bearing inscriptions in the Greek, Latin, and Ethiopian languages. This town has now not more than 600 houses, and a few manufactories of parchment and cotton stuffs. Gondar is stated by Bruce to contain 10,000 families and 100 Christian churches. One quarter is inhabited by Moors or Arabs. There is a good market; and the medium of exchange is gold, salt, and cotton cloth. The natives, whatever they might originally have been, are at present what the Arabs call them, a very mixed race, partaking much of the Arab and the Negro charac¬ ter ; and even their language, though confined to this great cluster of mountains, has a very considerable mixture of Arabic roots in it. Their manners are brutal, and their habits filthy. Their houses are mostly circular, and co¬ vered with conical-shaped roofs, which is the common form through the central parts of Africa, among the ne¬ groes, and down to the colony of the Cape of Good Hope. The children go naked to an advanced age. They are excessively indolent, and all the works of artisans and ar¬ tificers are in the hands of the Jews. The great lords have the newly-dressed food actually put into their mouths by their servants. They eat raw flesh, quivering almost with life, and placed between cakes of teff, made from a 232 AFRICA. Africa, species of small millet, or rather grass-seed (Poa Abys- ’ sinica); but they do not cut the flesh from the animal while alive, as Bruce has asserted. This is one of those romances, or exaggerated pictures, which brought his whole narrative into discredit; but which, though cir¬ cumstantially false, is substantially true. The principal alimentary plants of Abyssinia are millet, barley, wheat, maize, and various cucurbitaceous vegetables, and a con¬ siderable variety of fruit. Their domestic animals are small horses, buffaloes with long extended horns, cows with bumps between the shoulders, goats, and sheep ; be¬ sides asses and mules as beasts of burden. Most of the animals already enumerated as natives of Africa, both great and small, are to be found in Abyssinia. Their southern neighbours, the Gallas and Shangallas, have more of the negro and less of the Arab blood in their veins, and are somewhat less civilized. Beyond them to the southward and westward are the negroes, and to the eastward the Samaulies, who a little farther back in the interior take the name of Caffres. From the narrow entrance into the Red Sea, or Babel- mandib, along the southern coast of the Gulf of Aden, and from thence south by Cape Guardafui to Cape Bashas, in lat. 5. N., the whole territory of both coasts is inha¬ bited by the Samaulies, who are supposed to be a tribe of the same people as the Gallas, mixed, however, with the Arabs, who have from time immemorial occupied the east¬ ern coast of Africa down to Sofala, and whose language is partially incorporated with the native tongue, and traced through all the Samaulie or Caffre tribes, down to the co¬ lony of the Cape of Good Hope. The territory above mentioned was known to the ancients under the name of Asania, which is obviously taken from the Arabic name Azine, a descriptive term signifying a rocky, barren, in¬ accessible coast. The rocky cliffs rise out of the sea to the height of three and four hundred feet, and where they cease, in about 7. 40. N., the coast is sandy, but improves towards the equator. The want of harbours along this coast, the general barrenness of the country, the fierceness of the natives, and probably the difficulty of procuring negroes in this portion of Africa, have pre¬ vented any traffic of slaves in this quarter. From the equator to 10. 50. S., the whole country is extremely fertile, clothed with forests of the finest timber, well watered with numerous fine rivers, and contains many excellent ports. The river Jubo or Jabon, or, as the natives call it, Wooreenda, immediately under the line, is a very fine river, said to have its source in the mountains of Abyssinia. At Raas Boorghal, in lat. 1. 13. S., is port Durnford, having safe anchorage, and a fine river. The bays and harbours of Lamoo, Patta, Quayhoo, but particularly between Lamoo and Mandra Islands, in about the lat. 2. 15. S., afford safe and convenient anchorage. The port of Melinda, in lat. 3. 12. S., though deprived of its former splendour, possesses all the advantages of a good harbour. The pillar erected here by Vasco de Gama is still standing. The island and city of Mombas, placed in the centre of a most magnificent harbour, sufficient to contain the largest fleets, appears to be the central point of Arab commerce on this coast, more particularly in slaves, who are brought down in great numbers by the two fine rivers which fall into the southern and western sides of the harbour. The city is situated in lat. 4. 4. S. In 5. 30. S. is the Quillimane, one of the largest rivers on the east coast. Quiloa or Kulwa Island, like Mombas, is surrounded by a fine harbour, into which flow two large rivers. It is situated in lat. 9. S. There is also a port and river at Querimba, named Lindy, in lat. 9. 59. S.; and in 10. 7. is the great river and port of Monghow or Mongallow. The whole of this country to Cape Delgado is under the dominion of the imaum of Moscat, who an' points his officers to the several stations on the coast to levy taxes on the natives, and to participate, as he does largely, in the slave-trade. In fact, he is said to demand as his share of the revenues, one-half, careless how they are raised, or in what manner the people are oppressed The governor of Mombas, who exercises a sort of con¬ trol over all the other settlements, was so dissatisfied with the conduct of the imaum, that when Captain Owen called there, he waited on him at the head of 200 chiefs and at least 2000 of the inhabitants, to entreat that he would accept the country, in the name of the king of Eng. land, as a free gift, without any reservation or restriction and take it under his protection. His Majesty’s govern’ ment, however, did not think it proper to accept the offer of a territory, nominally at least, belonging to the imaum of Moscat. From Cape Delgado, in about the lat. 10., to De la Goa Bay in lat. 26., the whole extent of coast, though every, where inhabited by Arabs, and Samaulies or Caffres, is nominally belonging to the Portuguese, or the half-casts of that people, who are held in great contempt by the Arabs, some of whom told Captain Owen that they could at any time drive them away from every part of the coast, even their head-quarters, on the small island of Mozam¬ bique, if it were not for fear of drawing upon them the hostility of the English, under whose protection these Portuguese represent themselves to be. This settlement, which once bore some appearance of prosperity, while suffered to carry on an uninterrupted trade in slaves, is now reduced to a very contemptible state. The popula¬ tion consists of about 500 half-cast Portuguese, a mixed race of Arabs and Caffres, and an equal number of negro slaves, the whole not amounting to 3000 souls. The si¬ tuation for trade is admirable, and behind it is a fine deep bay, with rivers that communicate with the interior, from whence they still clandestinely procure slaves, a small quantity of gold dust, ivory, bees-wax, rice and other grain, fruits and vegetables. In the district of Sofala is also a fine river, named Quil¬ limane, or Great Water, which preserves its width of more than a mile up to the town, situated at the distance of twelve miles from its mouth, which, however, has a bar across it. Near the town it divides into two other branches, forming an extensive delta; and at Senne, it is formed by the union of two large rivers, the Jambeze from the south- west, and the Suaba from the north-west. To explore these rivers, Captain Owen sent Lieutenant Brown, Mr Forbes, a botanist, Assistant-surgeon Kilpatrick, an in¬ terpreter, and three servants, accompanied by a Portu¬ guese serjeant. They arrived at Senne all well; but after this the only account received of them was, that they had all died. Senne is about 250 miles from the mouth of the river, and another settlement called Tete, 150 miles farther in the interior. About a hundred miles farther west are the silver mines of Chicova; and on the Suaba, the other branch of the Quillimane, are Monica and Zamba, where it is supposed the gold mines are situated. Neither the one nor the other, however, is productive; and the pro¬ bability is, that the small quantity of gold brought down to Mozambique is collected by the natives from washing the sand and the alluvial soil of the rivers. Sofala itself is a miserable village, having a governor who is a petty trafficker, with a small fort, defended by about 60 soldiers, half black and half Portuguese; the inhabitants a mixture of Arabs, Moors, Portuguese, and Negroes ; the country fertile, producing rice, pulse, palms, wangoes, bananas, pine-apples, and numerous other fruits. •J? 2. AFRICA. 233 Af^' ?eof The river has a bar across its mouth, which is also the case with the fine river Inhambane, in lat~ 23.45. S. The whole of the coast of this district is intersected with rivers and hays, and fenced in, as it were, with numerous fertile islands, remarkable for the number of large trees of the cassuarina genus. The continent is here thickly covered with wood, and the native inhabitants appear to be spar¬ ingly scattered along the coast. The kingdom of Monomotapa, of whose queen we have heard nearly as much as of the queen of Sheba, is at the distance inland of about 40 days journey from Sofala. The natives are clothed in goat-skins, and subsist chiefly on rice and millet, manioc and sweet potatoes. Their weapons are bows and arrows. A small quantity of gold, topazes, and rubies, are brought down to Sofala, in ex¬ change for such luxuries as the governor, the chief trader, may have to dispose of. De la Goa Bay, where the Portuguese establishments, if they can be so called, end, in about the 26th parallel of latitude, has the two rivers Mafooma or English River falling into it from the west, and Mapoota from the south. A black Portuguese serjeant, or corporal, with a handful of men of the same colour, commands a miserable fort in this fine bay. From hence to the Great Fish River, in lat. 33^. S., where the colony of the Cape of Good Hope commences, the sea-coast is inhabited by the Hamboonas, the Mam- bookis, the Tambookis, the Zoolas, and the Koussie, or Ma- kousie, adjoining the Cape, all of whom are of the same race of people as those farther north; Caffres or Samaulies, or by whatever name they may be called—a mixed breed of Arabs and Negroes. The Zoolas, who are stationed along the coast of Natal, having driven down their next neigh¬ bours to the borders of the Cape colony, and alarmed its nearest residents, the Caffres, about 500 English troops were sent into the country of the latter to drive them back. They resisted, and a battle ensued. About ten thousand of them, armed with spears, and covered with shields of leather, stood the fire of musketry, which seemed to make but little impression. Our troops then charged them with the bayo¬ net, and some accounts state that more than a thousand were left dead on the field before they gave way, while the cowardly Caffres, on whose behalf they were thus attacked, looked on, or rather began to massacre the women and child¬ ren, and to plunder them of their cattle, which, however, was speedily put a stop to by the English forces. In fact, the cattle form the chief support of these roving tribes, who on moving them from place to place in search of food, en¬ croach upon some other tribe, and hostilities ensue, which, with occasional famines, keep down the population to the level of subsistence. A little millet (holcus sorghum), and a sort of tasteless water-melon, and a bitter gourd, are the only vegetables they attempt to cultivate. It is not known how far the Caffre race extend into the interior, but, from the number of negroes that are brought to every part of the coast, from the equator to Mozambique, and part of Sofala, it may be concluded that they extend to no very great distance ; nor is there any good authority for the great chain of mountains, which are called Lapoota or the Spine of the Earth, as laid down on the maps. It would seem, however, from the accounts drawn from some negro children brought down to Mozambique, that there must be high land in the interior, as they spoke of hunting the boar in the cold season, when “ they can walk on the water.” The colony of the Cape of Good Hope extends on the east to the Great Fish River, and on the north to the Gariep or Orange River, which empties itself into the Southern Atlantic in lat. 28. 50. S. While in the hands VOL. II. of the Dutch, this colony was little more than an inter- Africa, mediate convenient station between Holland and its In- dian possessions, from which it received tea, nankeens, muslins, spices, and other articles, in exchange for wheat and wine, which were raised chiefly by the labour of negro slaves; even the boors or farmers in the interior, who were of the laziest description of men, cultivating only what was barely sufficient for their owm families, and employing Hottentots to tend their cattle. The popula¬ tion of Europeans was very limited, and all in good cir¬ cumstances. Since it has become an English settlement, the population is supposed to have nearly doubled, and the slaves diminished more than one-half; and in the course of a few years they will probably disappear altogether. The colony, however, can never become of much value in an agricultural point of view, owing to the very great proportion of waste land, unfit either for culture or pas¬ turage, which is at least two-thirds of the whole. The frequent visitations of drought, rust, and locusts, make the crops of grain very uncertain, and numbers of cattle perish for want of food. The great value of this colony to England is its position as a half-way house to India, where troops required for the latter country become well- seasoned, and on an emergency can speedily be forward¬ ed thither, as has been done on several occasions. As a general emporium of commerce, there is not perhaps a spot on the globe more favourably situated ; but the East India Company have strong objections to its being made a free-port, or even to its receiving any India and China produce for the consumption of the natives, but such as may be carried thither in their own vessels. The exportable products of the Cape are, wine, dried fruits, hides, salted meat, ostrich feathers, leopard skins, a small quantity of ivory, whale-oil, wax, and a few other trifling articles, for which they receive clothing, furniture, and other manufactures from England. Almost every species of animal, already enumerated as belonging to Africa in general, is to be found within the limits of the colony; and nothing can exceed the beauty of the vege¬ table part of the creation, as our conservatories can testi¬ fy. About 300 species of heath are supposed to be scat¬ tered over the colony; those of protea are numerous, beautiful, and magnificent; the bulbous-rooted plants are inexhaustible; and those of a succulent nature, such as euphorbia, crassula, aloe, and cotelydon, in great variety and grandeur. Forest trees, however, are scarce, except along the sea-coast, and accacias or mimosas along the banks of some permanent or occasional stream. Oaks, chesnuts, and other European trees grow well in the valleys, where- ever they have been planted; and the fruit-trees of Eu¬ rope, with the exception of those of the apple and cherry, all do well; and figs, pomegranates, oranges, lemons, and limes, are everywhere met with in great abundance in this fine and healthful climate. The western coast of' the Cape colony is sandy and Western barren, with here and there a spring of water and a little coast from verdure in the valleys. On it is the beautiful harbour of t|‘e Cape to Saldanha, whose shores are surrounded by sterility. From ^ etlua- the Orange River to Cape Negro, in lat. 16. S., upwards of 1000 miles, the whole coast consists of sand-hills, with¬ out a tree or a drop of water, having only in all this dis¬ tance three bays entirely exposed to the north-west winds, the Great Fish Bay, Walvisch Bay, and Angra Pequina. From Cape Negro, where the hilly country commences, to the equator, are the Portuguese settle¬ ments of Caconda, Benguela, Angola, Congo, and Loango, of the wealth and splendour of which we read so much in the old accounts of the Jesuits, who, to magnify their own merits and the success of their missions, exaggerated and 2 c 234 AFRICA. Africa. Sierra Leone. falsified their reports and descriptions wherever they went. These colonies are now miserable in the extreme, and scarcely a trace remains among the wretched natives, a great part of whom are a sort of half-cast between Portu¬ guese and Negroes, of former prosperity, or of that religion to which these holy fathers represented many hundred thousands to have been converted. To add to the general stock of misery in which these countries are involved, the person who at present (1829) holds the throne of Portugal has banished thither several hundred families, who must perish from famine and the climate. Till within a few years, the governors and lieutenant-governors, and officers of black troops, and other employees, had subsisted en¬ tirely by the abominable traffic in slaves ; but this resource appears to have failed them, not in consequence of the ex¬ piration of the time allowed by treaty for carrying on that traffic,but because the interior hasbeen completely exhaust¬ ed of its negro population. Captain Tuckey’s unfortunate expedition afforded some insight into the interior of the dis¬ trict of Congo. The extraordinary mortality that took place was never satisfactorily explained. The climate, after pass¬ ing the falls, appears, by Captain Tuckey’s journal, to have been excellent, the thermometer having never descended below 60° in the night, and seldom rising above 76° of Fah¬ renheit during the day, and the atmosphere being remark¬ ably dry. The slave-dealers towards the lower part of the river are described as the vilest of mankind, a mongrel breed of French, Portuguese, and Negroes. Above the cataracts the negro population was far more respectable, but so indolent, that with difficulty they could be prevail¬ ed on to assist, on any terms, to push forward the canoes. Captain Tuckey states his reasons for concluding that the source of the Zaire must be to the northward of the equa¬ tor, probably in those high mountains, a portion of which are visible from the sea in the Bight of Biafra. Proceeding to the northward, and crossing the equa¬ tor, we arrive at the bottom of that great bay or indent generally known as the Gulf of Guinea, a part of which forms the Bights of Benin and Biafra. Beginning at Cape Palmas, the extreme western point of this gulf, we have in succession the Ivory Coast, the Gold Coast, and the Slave Coast, the last extending from the river Volta to Gabon under the line. The inhabitants of this great ex¬ tent of coast are nearly the same, very much corrupted by their intercourse with Europeans, more especially at those several places where European settlements have been formed. They are all intolerably lazy, and the richness of the soil, and the great heat and constant mois¬ ture, enable them to be so, and at the same time may be considered as some excuse for indolence. Nothing can exceed the fertility of the coast of Guinea. Maize, rice, holcus of various species, yams, cassava, sugar-cane, fruits of every kind common to tropical climates, spices, peppers, gums of five or six sorts, the oil, the tallow, and the butter-tree, cotton, indigo, and various dye-woods, are produced with little labour, and many of them spon¬ taneously. Behind the Ivory Coast elephants roam in the woods and savannahs, in the latter of which the grass and reeds are said to exceed the height of 20 feet, and into which these huge animals retire to rest: these are some¬ times caught by the negroes setting fire to the thickets, but mostly by pitting. In Bambouk and Akim, and various other places, gold-dust is collected in the sand brought down the mountain streams, but in no great quantity. Higher up the coast is the settlement of Sierra Leone, which, as a place for civilising the negroes by education and free labour, would appear to have entirely failed: it certainly is of very little value, either as a commercial or naval depot, and every body avoids it as much as possible, on account of its extreme insalubrity. Its chief value a national point of view is the great quantity of ship-timber, C. ^ said to be superior to oak, which is brought down the river from the interior, and imported at a lower price than Eng. lish oak bears in the market. To the northward of this the half-cast Portuguese have a slave-dealing settlement among the Bissagos Islands; and higher up on the coast is the English colony on the river Gambia; and lastly, the French settlement on the Senegal. The chief articles of the trade which is carried on at the last two settlements are spirituous liquors and tobacco ; in return for gums of different kinds, bees-wax, a litle gold-dust, and ivory. The territory in the neighbourhood of these rivers is in possession of various mixed tribes, Moors, Arabs, Berbers, and Negroes; but the pure negro is rarely found among them, except in a state of slavery. The Felatas, under the name of Foulahs, are numerous ; so are the Serrawolles of Galam, the Mandingos, the Bamboukis, the Feelops, the Jalofs, the Soosoos, and an endless number of tribes, half Mahometans, half Pagans, most of them of a treache¬ rous and inhuman disposition, very little advanced in the arts, conveniencies, and manners of civilized life, and al¬ most constantly at war with each other. The country in¬ habited by this description of people brings us to the commencement of the great desert of Zahara, the coast of which is occasionally inhabited by prowling Arabs looking out for shipwrecked vessels, which they plunder without mercy. This barren coast extends northerly as far as Suz, where the emperor of Morocco’s dominions may be said to commence, though the Moors and Berbers on this skirt of the desert are a lawless race, and scarcely pay al¬ legiance to any sovereign but of their own choosing. Why this Barbary state should be dignified with the Mo: name of Empire is by no means obvious, unless it be that the title of Sultan has been translated into that of Em¬ peror. The present ruler is a Shirif, or descendant of Mahomet. The country is of great extent, and very varied in its productions; but owing to the bad system of government, agriculture and commerce are both neglect¬ ed, and the population scanty, the highest estimate of which cannot be considered to reach five millions, though Jackson, the loosest of all writers on Africa, has swelled it to fifteen millions, which is absurd. The Atlas Moun¬ tains, which occupy the central parts, send forth their fertilizing streams in every direction ; and the perpe¬ tual snow which appears on one of the highest peaks, behind the city of Morocco, tempers the summer heat, and communicates a freshness to the climate, scarcely known in other parts of the African continent. Grain of every description may be raised in Morocco. All the fruits of Europe, and most of those of Asia, thrive re- ! markably well. The shrubby and herbaceous plants are rich and in great variety. The oaks of Atlas are of good dimensions, but forest trees in general are rather stunted in their growth. These are chiefly the quercus suber, and ilex, thuia, mimosa, cedar, walnut, and chesnut. The olive and argan (eleodendron) supply them with abundance of oil. They have black-cattle and broad¬ tailed sheep in abundance, and bees producing the finest honey and wax. But the late emperor Muley Soliman, in one of his despotic mandates, prohibited the exporta¬ tion of oil, wheat, and wool, three of the most productive articles, which at once impoverished the agriculturists,— so much indeed, that wheat and barley have since been imported from Europe; and the nephew, who usurped the sovereign power, ruined the merchants and manu¬ facturers of Fez by his excesses and extortions. All the foreign establishments at Mogadore have left the place, except one single English house. Only twelve small AFRICA. Afri> vessels entered that port during the year 1828, which amounted formerly to thirty or forty; and these twelve are stated to have found a bad market, and not half cargoes in return. The port of Santa Cruz has long been wholly abandoned by European traders, and the town is now little better than a heap of ruins. The trade from Tetuan, Tangier, and Rabat is very trifling. The present emperor Muley Abderahman, like some of his predecessors, has been mostly employed, since his ac¬ cession in 1821, in efforts to bring into proper submission his refractory subjects in the southern provinces, who have felt themselves strong enough to refuse paying contribu¬ tions; and in levying additional taxes, taking off heads, and confiscating the property of those who have any, parti¬ cularly that of Jews and Moorish merchants. Even the slave-trade with Soudan by means of the caravans has greatly diminished. There are very few Turks in Mo¬ rocco. The population consists chiefly of Moors, Arabs, Berbers, Negroes, with all their varied mixtures, and Jews. The last are subject to the worst treatment, but, as it has been stated, “ no insult, indignity, or oppression, prevents the Israelite from domiciliating himself wherever he hap¬ pens to fix his abode. He is a plant that seems to be suited for every soil, and generally thrives best when the pruning-knife is most applied. Among the Moors he is made to suffer beyond what any nature but that of a Jew could bear; yet such is the ignorance of the ruling powers and their Moorish subjects, that the affairs of state could hardly be carried on without him. Most of the trades and professions are exercised by Jews; they farm the re¬ venues; act as commissaries and custom-house officers, as secretaries and interpreters; they coin money; furnish and fabricate all the jewellery and silver ornaments and trappings for the sultans, beys, and bashaws, and their respective harems; and in return for all this they are op¬ pressed by the higher ranks, and reviled and insulted by the rabble.” Such is their situation in all the four Bar¬ bary states. Hie chief cities of Morocco are, the capital of that name, supposed to contain about 30,000 inhabitants ; Fez, about the same number ; Mequinez, not quite so many; Tetuan, on the coast, about 20,000; and Tangier, 16,000. The buildings are flat-roofed, and the streets narrow and dirty. On the south are Tafilet and Segilmessa, once populous cities, but now depending mostly on the caravans to Soudan, which resort to these places. Still farther south, and bordering on the desert, is the Bled-el-Jereed, or country of dates. Ihe manufactures are chiefly confined to cotton and woollen cloths, silks, paper, and morocco leather. ' The Morocco territory is separated from that of Algiers by the desert of Angara, on which the Arabs pursue lions, ostriches, and antelopes, and plunder the defenceless traveller. Ihe mountain chain of Atlas extends behind it, and separates it from the great desert. In front of these is a long tract of fertile country, productive of all mds of grain and good fruits. Numerous rills pour down tie sides of the mountains, some of which are frequently covered with snow, giving a freshness to the temperature, w inch is almost always agreeable. The southern parts of ie range of mountains, and various places from the ng lest Atlas to the Gulf of Sidra, or the Syrtis, are inha- 5 ’ by tnbes of Berbers, usually called Shillooks, who 'ery much resemble the Tuaricks of the desert. 1 he city of Algiers rises in the form of an amphitheatre •>n the side of a hill, surrounded by a wall, and having its ■■ea- rout completely protected by strong batteries, which ■lave resisted every attempt against them save one—that In 1 fei . x.rno.u*'b>—one °f the most daring, the most u ul in its issue, and most brilliant exploits on record. 235 The city is said to contain 80,000 inhabitants. It is placed Africa, in the midst of a country well clothed with all manner of' fruit-trees, among which are scattered a great number of villas or country seats, to which the inhabitants repair in the hot season. The city of Constantine is said to contain 100,000 souls. Its site is entirely covered with broken walls, cisterns, aqueducts, and other ruins. Shershell, the ancient Caesarea, is covered with similar ruins of great ex¬ tent and grandeur. Indeed the whole of this part of Africa exhibits the remains of temples, aqueducts, am¬ phitheatres, triumphal arches, and other ancient edifices of extraordinary magnificence. Besides these, numerous other cities and modern towns are found in the interior and along the sea-coast, as Mascara, Oran, and Bona; near the last of which is the great coral fishery. The army is composed of Turks, who elect the dey, whose arbitrary power is in some degree mitigated by the divan, composed of the oldest and highest of the military officers. He ac¬ knowledges the sovereignty of the grand signior, and pays him an annual tribute. One of the chief sources of re¬ venue is the monopoly of grain ; to which are added, con¬ fiscations, taxes on the Jews and other foreigners, and the sale and ransom of prisoners, which has been greatly diminished since the Barbary powers have been compell¬ ed, by the interference of England, to liberate all Christian slaves. Bordering on Algiers, and to the eastward of it, is Tunis. Tunis, once the flourishing capital of the Carthaginian power. The hereditary bey is neither Turk nor Moor, but the descendant of a Greek renegado and a Genoese slave. Christians and Jews are less subject in this state to oppression and insult than in any of the other three ; and the Tunisians are also less addicted to piracy. Their great pursuit is agriculture and commerce, which are mostly in the hands of the Moors; but a vast number of Nomade Arabs are scattered over the interior of the coun¬ try. The cattle and horses are small, but the sheep are of a large size. The southern side of the tail of the Atlas range of mountains is sandy and barren, and a desert in¬ tervenes between it and the oasis of Ghadamis, which, from its position, ought to belong to Tunis, but nominally is under the dominion of the bashaw of Tripoli. The crops of grain are very fine, and the Tunisians have all the fruits that are common to the other states. The city of Tunis, if we except Cairo, is the first in all Africa, and possesses a well-fortified harbour. The Go- letta, a strong fortress, commands the roadstead, and the entrance of the lagoon or lake, which, however, is navi¬ gable only by boats. The ruins of ancient Carthage ap¬ pear a little to the north-west of it. The ruins of the works that formed her harbour, and the remains of an aqueduct, are still visible. In the interior is the Arabian city of Cairoan, which for many centuries was reckoned the capital of Africa, but of which little is known at pre¬ sent. Its principal mosque is reported by the Moors to be supported by 500 columns of granite. Along the coast are several towns and small harbours, as Sooza, Gabes, and Porto-Farina, near which the ancient Utica was situ¬ ated, where the younger Cato underwent a voluntary death. In all the towns of this state are considerable manufac¬ tories of silks, velvets, cloths, and morocco leather, and a peculiar kind of red cloth cap, which is very much worn by the seamen and peasantry of the coasts of the Medi¬ terranean. The state of Tripoli may be said to expend from the Tripoli. Lesser Syrtis or Gulf of Gabes to the eastern extremity of Barca, on the confines of Egypt. On its deserts and its arid mountains are numerous tribes of Nomade Arabs, Moors, and Tuaricks or Berbers, who frequently threaten 236 AFRICA. Africa, the bashaw in his capital. It has a tolerably good har- hour, and a strong castle to command both it and the town. To the eastward is Lebida, the ancient Leptis Magna, where the remains of temples, triumphal arches, and aqueducts, are still visible. The French carried off a great number of large and beautiful columns; and Cap¬ tain Smyth of the British navy sent home several shafts and capitals, which were lying for a long time in the court-yard of the British Museum. Farther east is the town and bay of Mesurata, and beyond it the Libyan Pentapolis, the ruins of whose five cities, Cyrene, Barce, Ptolemais, Berenice, and Taukera, still exist, under names scarcely dissimilar from their ancient appellations, and are still inhabited as towns' and villages, but with a very different description of people. Cyrene was undoubtedly the most ancient and splendid of the Greek colonies on the coast of Africa, whose ruins and catacombs, scattered along the summit of the third stage of hills, or last terrace which overlooks the Mediterranean, are still magnificent. The succession of terraces corresponds very accurately with the description given of the face of the country by Herodotus; and among the splendid ruins still flows the limpid spring described by him, along whose verdant banks the Arab now pitches his tent. Tolemata or Pto¬ lemais, in the port of Barca, preserves its ancient walls, co¬ vered with inscriptions 5 and the ruins of it£ temples and arches are all to be traced. Flere, indeed, we are on , classic ground; and modern travellers have fancied even to have discovered the gardens of the Hesperides. At Derne the country puts on a beautiful appearance, and receives fertility from the rills descending from the moun¬ tains. It is governed by a bey appointed by the bashaw of Tripoli, and so is Bengazi. These two towns are in¬ habited by Moors, Jews, and Arabs; but the greater part of the country is in possession of the wandering tribes of Arabs, who pasture their flocks as far as the oasis of Audjela, and along the edge of the desert to Fezzan, both of which are, nominally at least, dependent on the bashaw of Tripoli. Of the sea-coast of this part of Africa, from Tripoli round the Greater Syrtis, of the Cyrenaica, and to the confines of Egypt, we have the best detailed in¬ formation as to its present state, its antiquities, and pro¬ ductions, from Della Celia and Mr Beechey. Interior of It is quite true, as Major Rennell has observed, that Northern “ nothing can evince the low state of African geography Africa. more than M. D’Anville’s having had recourse to the works of Ptolemy and Edrisi to compose the interior part of his map of Africa in 1749.” This map, and indeed all that have followed of the interior, are now (1829) ren¬ dered nearly worthless by the discoveries of modern tra¬ vellers. The first traveller who made much progress into the interior was Mungo Park, who proceeded from Pisa- nia, on the river Gambia, to Medina, Fatteconda, Kem- moo, Jarra in Ludimar, the frontier town of the Moors, who took him prisoner, and confined him at Benown for two months. On being released, he travelled, chiefly by the charity of negroes, through a wooded country to Sego, where he fell in with the Niger, so named by Leo Africanus, who supposed it to be the Niger of Pliny. From Sego, continuing his journey along the banks of the river, he reached Silla, from which place he deemed it prudent to return, on account of the jealousy of the Moors, whose ill treatment he had already experienced. Return¬ ing by a more southerly route, along the northern banks of the great river thus discovered, as far as Bammakoo, where it appears first to become navigable, and passing through Manding, Konkodoo, Dentila, Neola, and Tenda, he at length reached Medina on the Gambia, having add¬ ed greatly to our knowledge of this part of Africa. We have no account of his proceeding farther in his second journey than Sansanding, a little way beyond Sego ; and^ all account of his discoverieg from thence to Boussa, where he was wrecked, has perished with him. That he did so perish at that place, is rendered certain by the visit of Clapperton, and subsequently by that of his servant Lander. To Mr Browne we owe whatever particulars he was able!) to collect (and, being kept a prisoner, they were not many) concerning Darfoor and the position of the oasis and ruins of the temple of Jupiter Ammon; the latter of which were afterwards corroborated by Florneman. From a vocabulary of the language of the natives of this oasis, Mr Marsden came to the conclusion that they were the same people as the Tuaricks, who inhabit the western part of the great desert from Morocco to Timbuctoo. In this oasis, and that of Augela, the inhabitants grow a little grain, and cultivate fruits and vegetables, chiefly dates. The women are mostly employed in weaving a coarse woollen cloth, the only covering they wear. The largest of the several islands interspersed among the sands of the desert, or rather a cluster of them, is Fezzan, the ancient Garamantes, whose chief town is Mourzouk. This is the intermediate station in the desert for the trade of Bornou and Soudan with Egypt and Tripoli, receiving gold-dust, slaves, and horses, in exchange for salt, fruit, and vege¬ tables, goats and sheep for the caravans. The population of this oasis is stated to be from 70,000 to 80,000 souls. They cultivate barley, maize, pulse, and dates; figs and pomegranates grow in abundance. They have no water but what they receive from partial springs or deep wells, and it is generally brackish, from the salt and natron with which the soil abounds. The Zahara or Great Desert has also its oases, and 71 wadeys or valleys, in which springs of water are found,ra and shrubby plants, chiefly stunted accacias, and tufts ot'^1 grass. For hundreds of miles, however, the surface is one continued plain of sand, in some places blown up into high ridges, in others in undulating lines, like the waves of the sea. In parts of the desert, insulated hills of naked sand¬ stone rock, or ridges of hills, rise out of the sandy or stony surface, appearing like so many islands in the ocean. Many indeed have supposed that the Zahara must once have been the bed of the ocean, judging from the springs and pools of salt water, the flags of rock-salt, the beds of natron, and the saline particles that abound in the sand, and also from the shells and fragments of marine animals that are found in the limestone of Augela and other parts of the desert. On the eastern side is the Bohr Bellama, or sea without water; and Riley describes an immense ravine on the side of the Atlantic, running from the sea¬ shore more than 300 miles into the interior, full of salt water springs, and the sandy surface incrusted with ma¬ rine salt, which “ crumbled,” he says, “ under the feet of the camels like a crust of snow.” The banks of this deep ravine were distant from each other eight or ten miles, and were from 500 to 600 feet high. This valley Riley calls the bed of an arm of the sea, and supposes it to lie somewhere about the 20th parallel of latitude. Other travellers describe ravines of the same kind between the southern foot of the Atlas Mountains and the Zahara, like so many deep beds of a formerly existing sea, with incrustations of salt, rolled pebbles, and broken shells. It would be very desirable to trace the levels somewhere across the northern commencement of the Zahara, from the bottom of the Gulf of Syrtis to the Atlantic. We know nothing of the southern face of the Mauritanian Atlas, and the plains of Segilmessa, and the Bled-el- Jereed, or land of dates; and we cannot help thinking, ria /V ’alia. ,;eai AFRICA. 237 f, t}jat while we are sending out travellers to perish in the central parts of Africa, it would be as well, in the first place, to obtain a knowledge of the emperor of Morocco’s dominions; more especially of those parts to the southward of Atlas, and contiguous to the Great Desert. It has been suggested that the whole country between the Syrtis and the Atlantic, over which the Atlas chain extends, may have once been insulated, and in that state formed the celebrated Atlantis. This, however, is not very probable, but might easily be determined by a series of levels. ny The Zahara, miserable as it is, is not wholly without ants ■ inhabitants. On the western shore are scattered a few lie I Moorish and Arab shepherds and goat-herds, usually ;rt. looking out for plunder of shipwrecks. Towards the cen¬ tre are the Tuaricks, traders in salt, and robbers of the caravans; and to the eastward, chiefly in the neighbour¬ hood of the salt-water pools and marshes of Bilmah, are the Tibboos, a less pure people than the Tuaricks, who also collect-salt for the Bornou market, and feed a few sheep and goats. ouda The Desert ceases in about 15. north latitude, sloping gradually down to the fertile and well-watered countries of Bornou on the east, Houssa in the centre, and the re¬ gions already mentioned to the westward of Timbuctoo. Houssa and Bornou collectively comprehend that region of Africa known by the name of Soudan, or Land of the Blacks: the former is under the rule of the Sultan Bello, a descendant of the Foula tribe, called by the negroes Foulatas or Fellatas; and the latter is governed by the Sheik el Kanemy of some Arab tribe. These two chiefs, dividing this fine country between them, are, or recently were, in a state of hostility, by which the poor and peaceable negroes are made to suffer greatly. The elite of the black troops of Bornou are habited in coats of mail, composed of iron chains, with helmets or skull-caps of the same metal. The heads of their horses are also defended by plates of iron or brass, sufficient room being left only for the eyes of the animal, irnop There are 13 principal towns in Bornou. Kouka, the modern capital, is situated on the eastern border of the lake Tsad. Among the other principal towns are Mew Birnie, Old Birnie, Affagy, Angola, Kabshary, Showy, and Angornow; the last of which is said to be the largest town in Bornou, and supposed to contain about 30,000 inha¬ bitants. The market held at this place every Wednesday, is said by Denham to be attended sometimes by 80,000 or 100,000 persons. Bornou is intersected by two considerable rivers which fall into the Tsad; the Yeou, which has its rise in a ridge of hills about Katagum, and which divide this country from that of the Fellatas; and the Shary, whose source is unknown, but which falls into the lake from the southward. Kanem, to the north of the lake, and Baghermi to the westward, are dependent on Bornou; but the coun¬ try to the southward of it, and as far as the great range of mountains, is in possession of the Fellatas. On all sides of the lake are tribes of Arabs in great numbers, particular¬ ly those of the Shoua tribe of Beni Hassan, feeding their numerous flocks and herds. Ihe climate is far from being healthful. Though situated between the 10th and 15th parallels of latitude, the cold of winter is sometimes very severe, the thermometer rare¬ ly reaching 74° or 75°, while in the mornings it usually stands at 58° or 60°. In summer it rises sometimes to 10o° and 107°, with suffocating and scorching winds from the south and south-east. During the rains of summer, from the extreme flatness of the country, tracts of many miles in extent are converted into lakes. The soil is rich, but the people are indolent, and cultivate little for food but a species of millet, which they call gressub, and three 01 tour kinds of beans known by the name of gufooly, the common food of slaves and the poorer class of people. Indian Africa, corn, cotton and indigo, with a little senna, make up nearly the catalogue of their husbandry. Indigo indeed grows wild, and with it they dye their blue tobes or frocks. ^They have domestic fowls in great numbers; and all the quad¬ rupeds and birds which have been already mentioned, besides many others, are natives of the woods, the lakes, and the plains of Bornou. They have little commerce except with the people of Fezzan and Tripoli, chiefly sup¬ plying the Moors with slaves, horses, elephants’ tusks, and ostrich feathers, receiving in return red caps, brass basins, coral, fire-arms, powder and shot, swords, and salt. The Soudan population consisted originally of negroes; Houssa. but the Arabs, and the Moors, and the Berbers have con-the Fellata verted it into a mixed race, in which not only the features country* have been changed, but the native simplicity of the pure Ethiopian destroyed, if we may judge from the character and disposition of the unmixed negroes, whom Clapperton met with to the southward, beyond the line to which the Fellatas had carried their conquests. Corrupted as they are within the limits subjected by these people, Clapper- ton speaks of them in high terms of praise. In his way to Soccatoo, the residence of Bello, the country not only im¬ proved in appearance, from the moment he crossed the Bornou boundary, but the valleys were well peopled and cultivated, and the plains were covered with herds of cattle. Crowds of people were on the road from the market of Kano, bearing their purchases on bullocks, on asses, or on their heads. This city, the Ghana of the Arabs, is the great emporium of Houssa, about 15 miles in circumference, surrounded with a clay wall about 30 feet high, having a dry ditch within and without. The space within contains fields, orchards, and gardens. It is said to contain from 30,000 to 40,000 inhabitants. The market is well stocked with goods from every part of Northern Africa, and with European articles, even to English um¬ brellas. From Kano to Soccatoo the country increased in population, and town followed town in quick succession, most of them surrounded with walls and ditches. Clap¬ perton says that this part of the country resembled one of our English ornamented parks, clothed with woods and clumps of trees.. Bello sent out 150 of his horsemen with drums and trumpets to meet this traveller, and escort him to Soccatoo. This city he considered to be the most populous of any he had met with in Africa, though it was founded only in 1805 ; but the mud walls of an African town are soon run up, and as soon demolished. It is situated in long. 6. 12. E. lat. 13. 5. N., near to a small river which, rising in the hills between Kashna and Kano, and running to the west, is said to fall into the Quorra (Niger) at four days’ journey to the westward of Soccatoo. There is one city of considerable strength at no great distance from Socca¬ too, which Bello has not been able to conquer. It is named Goober, and the people, by the sultan’s own ac¬ count, “are free-born, because their origin is from the Copts of Egypt.” Clapperton, on his second visit, was present at the siege of this place, of which he gives an amusing account, not very creditable to the army of Bello. By the second journey of this unfortunate traveller we Negro na- are made acquainted with the manners and habits of a lions of negro population in the interior, behind or to the north-in¬ ward of the range of mountains that are supposed to crossnor* Northern Africa like a belt. From the Bight of Benin to Soccatoo large and populous kingdoms follow each other, containing towns and cities of mud houses, surrounded with mud walls, peopled with 10,000, 15,000, 20,000, and even 40,000 inhabitants ; the country well cultivated, and the people employed in various manufactures for domestic 238 AFRICA. Africa. use; such as weaving, dying, tanning, working in iron and other metals, and in pottery. In all the towns he found them a good-humoured, but a vitious and licentious set, both male and female ; fond of music, dancing, and drink¬ ing booza; extremely superstitious, and placing confidence in the power of various charms. The chief or king of Yourriba had as many wives, he told Clapperton, as, if linked, hand in hand, would reach from one end of his kingdom to the other; but these queens are less for luxury than for use, being employed in all kinds of hard labour. The emperor of China does not receive from his ministers more humiliating submission than does the king of Your¬ riba from his black vassals, who fall flat on their bellies before him, and cover themselves with dust. Next to Yourriba is the kingdom of Borghoo, whose capital is Kiama, famous for its horses. The sultan is at¬ tended by a body-guard of young females, when he makes his appearance in public. He waited on Clapperton, at¬ tended by six naked young girls, from 15 to 17 years of age, a white bandeau or fillet of white cloth round the fore-head, and a string of beads round the waist, being their only clothing. Each carried three light spears. “ Their light form, the vivacity of their eyes, and the ease with which they appeared to fty over the ground, made them appear something more than mortal, as they flew alongside his horse.” The subjects of Borghoo had the reputation of being great robbers, but Clapperton received nothing but civility in passing through their country. Kiama is said to contain 30,000 inhabitants. From hence he proceeded to Wawa, a town with 18,000 inhabitants, also belonging to Borghoo. From Wawa our traveller proceeded to the northward as far as Boussa, situated on the Quorra, for the purpose of gaining information respecting the death of Mungo Park, which happened at this spot of the river. The re¬ ports varied, though they all agreed in the main point, that the boat upset over a ledge of rocks which here crosses the river, and the few that were in her were un¬ fortunately drowned. It appears, too, that by a mistake they were engaged in hostility at the moment with the natives on shore. On Lander’s return, the sultan of Boussa employed him in cleaning some muskets, six of which had the Tower mark upon them. Clapperton got some indirect information respecting Park’s papers, but it appeared doubtful whether they were still in exist¬ ence. On his return to Wawa, he fell in with a coffle or caravan, from Ashantee to Houssa, which occupied a long line of march, consisting of bullocks, asses, horses, and wo¬ men and men to the amount of a thousand persons. From Wawa he proceeded to the ferry of the river Quorra, which was here about the width of the Thames at West¬ minster. Having crossed the river, the first town was Koolfa, in Nyffe, a walled town, containing from twelve to fifteen thousand inhabitants, Mussulmans and Pagans. Here the whole night was spent in singing, dancing, and drinking booza. Beyond this, towns and villages increas¬ ed in number, and the fields were better cultivated than had hitherto been the case ; but every labourer was armed to protect himself against the inroads of the Fellatas, who were very numerous in this part of Africa. Zaria, the capital of Zeg-zeg, is a large Fellata city, as populous as Kano, and has several Mahometan mosques with minarets; and the houses are flat-roofed. The en¬ virons are stated to be very beautiful and well cultivated, which continues to be the character of the country the whole way from thence to Kano. On the whole, it may be collected from this interesting journey of Clapperton, that though sobriety and chastity form no part of the character of the native negroes, they are a happy, kind-hearted, and sociable people, undergoing just as much labour as i? necessary to procure them food, clothing,and booza; and v. having accomplished this, preferring to bask in the sun' or to sleep in the shade all day, and to commit all kinds I of debauchery in the night; just like the booza-drinkers of Berber and Shendi, as described by the late Mr Burckhardt. It would appear, from the journal of Clapperton’s ser¬ vant, on his return by a more easterly route, that the in¬ habitants are several degrees lower in the scale of civili- sation than those more to the westward. In one place men, women, and children exposed themselves without any covering whatever; and a range of hills to the east¬ ward of his route was pointed out as being inhabited by a ferocious tribe of people called Yam-yams, who were declared by all to be cannibals. The Sultan Bello assur- ed Clapperton that he had seen these people eat human flesh. These, however, may be considered as exceptions. The great mass of the people are gentle and docile; but so long as the Fellatas send out their marauding parties to carry off slaves and cattle, there is little reason to ex- pect they will make any progress in civilisation. Domes¬ tic slavery has in all probability existed among them for ages past, and even yet the slave appears to be treated like any other member of the family; but the foreign slave-trade, that greatest of all curses, leads to perpetual wars among neighbouring tribes, it being well known that a coffle of human beings is a species of traffic easiest to be conveyed to the sea-coast, and fetches there the high¬ est prices, for which the venders are enabled to purchase in return ardent spirits and other articles suited to their depraved appetites. There is one way, and but one, of putting an end to this infamous traffic, and that is by all the maritime nations of Europe and America declaring it to be piracy ; but there are too many interested in its con¬ tinuance to allow us to indulge a hope that this will ever be done. The discoveries of Clapperton and Denham have done In much to reform the geography of Northern Africa, thege* maps of which were disgraceful to that branch of know-of ledge in the nineteenth century. All those gratuitous611 lakes, rivers, and mountains, put down at random to fill up the vacant paper, may now be swept away, and those cities or towns that do exist, be placed in their proper situations; some of which, before the late expeditions, were from 300 to 500 miles out of their true positions. The Arab writers, from Edrisi downwards, appear to have been wholly ignorant of the course of the Joliba or Quorra, some making it run directly eastward, as far as the Nile of Egypt, and others in a contrary direction. Some placed the cities of Kashna, Kano, Nyffe, &c. along its banks, all in an easterly series ; mistaking possibly, as they make no use of river navigation, the Yeou for a continuation of the said Quorra; a mistake that a very ingenious French writer has fallen into, even subsequently to the publication of Clapperton’s journal; and an English author has also done the same, and carried its waters under ground through the Great Desert, and into the Gulf of the Syrtis. We now know that, at some distance beyond Timbuctoo, the Joliba or Quorra, the Niger of modern days, turns off to the southward, passes to the westward of Soccatoo, through Boussa, where Park was wrecked, skirts the province of Nyffe, and continues to flow southerly to at least the 9th parallel of latitude; and here all information as to its course ceases. But there can only be two alternatives,— either that it penetrates the range of granite mountains, whose width is somewhere about 80 miles, and height from 2000 to 3000 feet, and falls into the Bight of Benin, through the river Formosa,—or, that it turns off to the % '"V Fwir A F R A F R 239 eastward, joins the Shary, and falls into the lake Tsad. Tes- of the continuous low swampy country reported to extend Africa 1 timonies, such as they are, have been procured in favour easterly from Bornou, in which the lake Fittre and other - || (tfric of both suppositions ; and if those for the latter course lakes are said to be situated.

In what direction the one and the same river: they have the same character inV^v^N^ waters of the Tsad discharge themselves, is as yet mere all respects; the same high banks, with the same dark soil, conjecture, as little is known for certain to the eastward of which gives a colour to the water: the same birds, the that lake; but the water of the lake being at all times fresh, same fish, and the same plants, accompany both ; but the which it could not be if discharged only by evaporation, Bahr-el-Abiad and the Nile are totally different. Low there must be some outlet, and that outlet will probably meadow banks accompany the former, as far as it has been be found on the yet unexamined eastern side, creeping traced; the birds, the fish, and the animals, are wholly on in a connected chain of nearly stagnant pools to the distinct. The elephant, the hippopotamus, and the rhino- “ dead-flowing” stream of the Bahr-el-Abiad. ceros, are here found in whole herds. They are unknown The Bahr-el-Abiad, as far as it has yet been traced in the neighbourhood of the Nile. The water of the one from its junction with the Nile, strongly favours this suppo- is black and turbid; of the other it is of a white opal sition. It has been ascended as far as Aleis, by Monsieur colour. The only difficulty in exploring this interesting Linant, in the employ of the African Association. It has river upwards seems to be the hostility of a tribe, at 150 or been ascended by M. Rouppel; and Lord Prudhoe and 200 miles from its junction with the Nile, called Shillooks, Major Felix ascended it to a considerable distance, and who are a large race of men, entirely black, and without obtained some curious information of the country through clothing, and are represented by their lower neighbours, which it passes, and the singular character of the river, not exactly as cannibals, for they never can want fish to Foragreat part of the year it is very shallow, and the water eat, but as a very fierce and savage race. But the real nearly stagnant; its width extends from two to twenty character of people living in a savage state is not to be miles;and it is thickly studded with islands that are cover- procured from their neighbours, especially when in a state edv/ith fine forest-trees. In this state it resembles an end- of warfare with each other. The Shillooks, however, may less lake rather than a river; but when the freshes come easily be passed, by proceeding through the Denka coun¬ down, about the same time as the Nile begins to swell, try on the right bank, or to the southward between the they are not gradual, like those of that river, but the tor- mountains and the Bahr-el-Abiad, where an intelligent rent rises with great rapidity, sweeping all before it, and sheik of the name of Idrees Adelan resides; who, being bringing down most extraordinary multitudes of fish, now subject to the pasha of Egypt, would readily conduct These circumstances led the travellers to conclude that any traveller, recommended by the pasha, beyond the it was supplied from some great reservoir far in the west, territory of these formidable blacks, whese would proba- and that tliis reservoir is probably the lake Tsad. Some bly be met some of those pastoral tribes of Arabs that are of the officers of the pasha of Egypt’s army had been known to feed their flocks along this prolonged valley of nearly 400 miles up the river, still coming from the set- Soudan, even to the confines of Boraou. An expedition ting sun; and in that direction not a mountain nor a hill of from the Nile to Bornou through this tract of country, the any size was visible. It would seem, therefore, to form a most fertile probably in the whole interior, would afford i sort of great drain to carry off the waters of Bornou, and materials to complete the geography of Northern Africa. (m.) AFRICAN COMPANY. See Company. AFRICAN INSTITUTION. This institution was formed in 1807. Its general objects, and the views which influenced its formation, are clearly stated in the follow¬ ing resolutions, adopted at the constituent meeting, held on the 14th of April 1807. “ 1. That this meeting is deeply impressed with a sense of the enormous wrongs which the natives of Africa have suffered in their intercourse with Europe; and, from a desire to repair those wrongs, as well as from general feelings of benevolence, is anxious to adopt such mea¬ sures as are best calculated to promote their civilisation and happiness. “ 2. That the approaching cessation of the slave-trade, hitherto carried on by Great Britain, America, and Den¬ mark, will, in a considerable degree, remove the barrier j jvhich has so long obstructed the natural course of social improvement in Africa; and that the way will be thereby opened for introducing the comforts and arts of a more civilized state of society. ,41 That the happiest effects may be reasonably anti¬ cipated from diffusing useful knowledge and exciting in¬ dustry among the inhabitants of Africa, and from obtain¬ ing and circulating throughout this country more ample mul authentic information concerning the agricultural mid commercial faculties of that vast continent; and that, through the judicious prosecution of these benevolent en¬ deavours, we may ultimately look forward to the esta¬ blishment, in the room of that traffic by which Africa has been so long degraded, of a legitimate and far more ex¬ tended commerce, beneficial alike to the natives of Africa and to the manufacturers of Great Britain and Ireland.” The particular means which this society proposes to employ for promoting civilisation and improvement in Africa, are of the following kind:— “ L To collect and diffuse, throughout this country, accurate information respecting the natural productions of Africa, and, in general, respecting the agricultural and commercial capacities of the African continent, and the intellectual, moral, and political condition of its inha¬ bitants. “ 2. To promote the instruction of the Africans in let¬ ters and in useful knowledge, and to cultivate a friendly connection with the natives of that continent. “ 3. To endeavour to enlighten the minds of the Afri¬ cans with respect to their true interests, and to diffuse information amongst them respecting the means whereby they may improve the present opportunity of substituting a beneficial commerce in place of the slave-trade. “ 4. To introduce amongst them such of the improve¬ ments and useful arts of Europe as ax-e suited to their condition. “ 5. To promote the cultivation of the African soil, not only by exciting and directing the industry of the i 240 A G A A G A African natives, but by furnishing, where it may appear advan- Institution tageous to do so, useful seeds and plants, and implements II of husbandry. “ 6. To introduce amongst the inhabitants beneficial medical discoveries. “ 7. To obtain a knowledge of the principal languages of Africa, and, as has already been found to be practi¬ cable, to reduce them to writing, with a view to facilitate the diffusion of information among the natives of that country. “ 8. To employ suitable agents, and to establish corre¬ spondences as shall appear advisable, and to encourage and revvard individual enterprise and exertion in promot¬ ing any of the purposes of the institution.” The management of the affairs of this institution is vested in a patron and president, 20 vice-presidents, a treasurer, and a board of 36 directors. These offi¬ cers are chosen annually from among that class of the subscribers who are called governors of the institution. Those who subscribe 60 guineas at one time become he¬ reditary governors; but 30 guineas subscribed at one time makes the subscriber a governor for life; or three guineas annually, a governor during the continuance of this annual subscription. Every subscriber of one guinea becomes an ordinary member, and continues so during the continuance of his subscription. The proceedings of the society are fully detailed in its annual reports, which are regularly published. These re¬ ports contain much valuable and interesting information in regard to Africa, and the means of civilizing it. AFRICANUS, Junius, an excellent historian of the third century, the author of a chronicle which was great¬ ly esteemed, and in which he reckons 5500 years from the creation of the world to Julius Csesar. This work, of which we have now no more than what is to be found in Eusebius, ended at the 221st year of the vulgar era. Africanus also wrote a letter to Origen on the history of Susanna, which he reckoned supposititious; and we have still a letter of his to Aristides, in which he reconciles the seeming contradictions in the two genealogies of Christ recorded by St Matthew and St Luke. AFSLAGERS, persons appointed by the burgomasters of Amsterdam to preside over the public sales made in that city. They must always have a clerk of the secre¬ tary’s office with them, to take an account of the sale. They correspond to our brokers, or auctioneers. AFT, in the sea language, the same with Abaft. AFTERMATH, in Husbandry, signifies the grass which springs or grows up after mowing. AFTERNOON, the latter half of the artificial day, or that space between noon and night. AFWESTAD, a large copper-work belonging to the crown of Sweden, which lies on the Dala, in the province of Dalecarlia, in Sweden. It looks like a town, and has its own church. Here they make copper-plates; and have a mint for small silver coin, as well as a royal post- house. Long. 14. 10. E. Lat. 58. 10. N. AGA, in the Turkish language, signifies a great lord or commander. Hence the aga of the janizaries is the com- mander-in-chief of that corps; as the general of horse is denominated spachiclar aga. The aga of the janizaries is an officer of great importance. He is the only person who is allowed to appear before the grand signior without his arms across his breast in the posture of a slave. Eu¬ nuchs at Constantinople are in possession of most of the principal posts of the seraglio: the title aga is given to them all, whether in or out of employment. This title is also given to all rich men without employ, and especially to wealthy landholders. We find also agas in other countries. The chief officers under the khan of Tartary are called by this name; and among the Algerines we read of agas chosen from amon? the boluk bashis (the first rank of military officers), and'' sent to govern in the chief towns and garrisons of that state. The aga of Algiers is the president of the divan or senate. For some years the aga was the supreme officer, and governed the state in place of the bashaw whose power dwindled to a shadow. But the soldiery rising against the boluk bashis or agas, massacred most of them, and transferred the sovereign power to the caliph, with the title of Dey or King. AGADES, a kingdom and city of Negroland, in Africa. It lies nearly under the tropic of Cancer, between Gubur and Cano. The town stands on a river that falls into the Niger; it is walled, and the king’s palace is in the midst of it. The king has a retinue, who serve as a guard. The inhabitants are not so black as other negroes, and consist of merchants and artificers. Those that inhabit the fields are shepherds or herdsmen, whose cottages are made of boughs, and are carried about from place to place on the backs of oxen. They are fixed on the spot of ground where they intend to feed their cattle. The houses in the city are stately, and built after the Barbary fashion. This kingdom was, and may be still, tributary to the king of Timbuctoo. It is well watered; and there is great plenty of grass, cattle, senna, and manna. The prevailing religion is the Mahometan, but it is not rigidly practised. Long. 9. 19. E. Lat. 26. 10. N. AGALMATA, in Antiquity, a term originally used to signify any kind of ornaments in a temple, but afterwards for the statues only, which were most conspicuous. AGAMEMNON, the son of Atreus by Aerope, was captain-general of the Trojan expedition. It was foretold to him by Cassandra, that his wife Clytemnestra would be his death: yet he returned to her; and accordingly was slain by iEgisthus, who had gained upon his wife in his absence,, and by her means got the government intol his own hands. AGAN, one of the Ladrone Islands. The circumnavi¬ gator Magellan was assassinated here in the year 1525. AGANIPPE, in Antiquity, a fountain of Bceotia, at Mount Helicon, on the borders between Phocis and Boeo- tia, sacred to the Muses, and running into the river Per- messus. Ovid seems to make Aganippe and Hippocrme the same. Serenus more truly distinguishes them, and ascribes the blending of them to poetical licence. AGANIPPIDES, in ancient poetry, a designation given to the Muses, from a fountain of Mount Helicon called Aganippe. - AGAPE, in Ecclesiastical History, the love-feast, or feast of charity, in use among the primitive Christians, when a liberal contribution was made by the rich to feed the poor. The word is Greek, and signifies love. St Chrysostom gives the following account of this feast, which he derives from the apostolical practice. He says, “ The first Christians had all things in common, as we read in the Acts of the Apostles ; but when that equality of possessions ceased, as it did even in the apostles’ time, the agape or love-feast was substituted in the room of it. Upon certain days, after partaking of the Lord’s Supper, they met at a common feast; the rich bringing provisions, and the poor who had nothing being invited. It was always attended with receiving the holy sacrament; but there is some difference between the ancient and mo¬ dern interpreters as to the circumstance of time, viz. whe¬ ther this feast was held before or after the communion. St Chrysostom is of the latter opinion ; the learned Dr Cave of the former. These love-feasts, during the first three ape, ■A A G A centuries, were held in the church without scandal or ^ offence; but in aftertimes the heathens began to tax Agf- them with impurity. This gave occasion to a reformation ^'^of these agapa. The kiss of charity, with which the cere¬ mony used to end, was no longer given between different sexes; and it was expressly forbidden to have any beds or couches for the conveniency of those who should be disposed to eat more at their ease. Notwithstanding these precautions, the abuses committed in them became so notorious, that the holding of them (in churches at least) was solemnly condemned, at the council of Carthage, in the year 307. AGAPET7E, in Ecclesiastical History, a name given to certain virgins and widows, who, in the ancient church, associated themselves with and attended on ecclesiastics, out of a motive of piety and charity. In the primitive days there were women instituted dea¬ conesses, who, devoting themselves to the service of the church, took up their abode with the ministers, and assist¬ ed them in their functions. In the fervour of the primi¬ tive piety, there was nothing scandalous in these societies; but they afterwards degenerated into libertinism; inso¬ much that St Jerome asks, with indignation, unde aga- petarum pestis in ecclesias introiit ? This gave occasion for councils to suppress them. St Athanasius mentions a priest, named Leontius, who, to remove all occasion of suspicion, offered to mutilate himself, to preserve his be¬ loved companion. AGARD, Arthur, a learned English antiquary, born at Foston, in Derbyshire, in the year 1540. His fondness for English antiquities induced him to make many large collections; and his office as deputy chamberlain of the exchequer, which he held 45 years, gave him great oppor¬ tunities of acquiring skill in that study. Similarity of taste brought him acquainted with Sir Robert Cotton and other learned men, who associated themselves under the name of The Society of Antiquaries, of which society Mr Agard was a conspicuous member. He made the Domesday book his peculiar study, and composed a work purposely to explain it, under the title of Tractatus de Usu et obscurioribus Verbis libri de Domesday. He also compiled a book for the service of his successors in office, which he deposited with the officers of the king’s receipt, as a proper index for succeeding officers. All the rest of his collections, containing at least 20 volumes, he be¬ queathed to Sir Robert Cotton; and died in 1615. AGARIC Mineral, a marly earth, resembling the vegetable of that name in colour and texture. AGARO, an island of Sweden, in the province of West- manland, on the same estuary on which Stockholm is si¬ tuated. AGATE, or Achat (among the Greeks and Latins Ayarjjf and Achates, from a river in Sicily, on the banks of which it was first found), a very extensive genus of the semipellucid gems. These stones are variegated with veins and clouds, but lave no zones like those of the onyx. They are com¬ posed of crystal debased by a large quantity of earth, and neither formed by repeated incrustations round a cen- ra nucleus, nor made up of plates laid evenly on one an- 0 ier, but are merely the effect of one simple concretion, an variegated only by the disposition given by the fluid ey were formed in to their differently coloured veins or matters. Agates are arranged according to the different colours ieir ground. Of those with a white ground there are iree species. 1. The dendrachtes, mocoa stone, or arbo- uiii?*. seems to be the same with what some vo^8 Ca ^16 ac^a^es wRh rosemary in the middle, A G A 241 Agate. and others achates wuh little branches of black leaves. 2. the dull milhy-loohing agate. This, though greatly in-' fenor to the former, is yet a very beautiful stone. It is common on the shores of rivers in the East Indies, and also m Germany and some other parts of Europe. Our lapidaiies cut it into counters for card-playing, and other toys of small value. 3. The lead-coloured agate, called the phassachates by the ancients. . Of the agates with a reddish ground there are four spe¬ cies. 1. An impure one of a flesh-coloured white, which is but of little beauty in comparison with other abates. The admixture of flesh colour is but very slight; and it is often found without any clouds, veins, or other varie¬ gations ; but sometimes it is prettily veined or variegated with spots of irregular figures, having fimbriated edges. It is found in Germany, Italy, and some other parts of Europe, and is wrought into toys of small value, and often into the German gunflints. It has been sometimes found with evident specimens of the perfect mosses bedded deep in it. 2. That of a pure blood colour, called hcema- chates, or the bloody agate, by the ancients. 3. The clouded and spotted agate, of a pale flesh colour, called by the ancients the carnelian achates or sardachates. 4. The red-lead coloured one, variegated with yellow, called the coral agate, or corolla achates, by the ancients! Of the agates with a yellowish ground there are only two known species; the one of the colour of yellow wax, called cerachates by the ancients; the other a very elegant stone, of a yellow ground, variegated with white, black,^and green, called the leonina, and leonteseres, by the ancients. Lastly, Of the agates with a greenish ground, there is only one known species, called by the ancients jas- pachates. Of all these species there are a great many varieties, some of them having upon them natural representations of men and different kinds of animals, &c. Those repre¬ sentations are not confined to the agates whose ground is of any particular colour, but are occasionally found on all the different species. Velschius had in his custody a flesh-coloured agate, on one side of which appeared a half-moon in great perfection, represented by a milky semicircle; on the other side, the phases of vesper, or the evening star; whence he denominated it an aphrodisian agate. An agate is mentioned by Kircher,1 on which i Ephav. was the representation of a heroine armed; and one in German. the church of St Mark in Venice has the representation dec-i-an. 1. of a king’s head adorned with a diadem. On another, in0^* 151* the museum of the prince of Gonzaga, was represented the body of a man with all his clothes, in a running pos¬ ture. A still more curious one is mentioned by De Boot,2 wherein appears a circle struck in brown, as ex-2 De Gem actly as if done with a pair of compasses, and in the 1. ii. c. 95.' middle of the circle the exact figure of a bishop with a mitre on: but inverting the stone a little, another figure appears; and if it is turned yet farther, two others ap¬ pear, the one of a man, and the other of a woman. But the most celebrated agate of this kind was that of Pyrrhus, wherein were represented the nine Muses, with their pro¬ per attributes, and Apollo in the middle playing on the harp.3 We have also seen accounts of an oriental agate, 3 pih, of such size as to be fashioned into a cup, whose dia-i. xxxvii. meter is an ell abating two inches. In the cavity isc. 3. found delineated in black specks, b. xristor. s. xxx. Other agates have also been found, representing the num¬ bers 4191, 191; whence they were called arithmetical agates, as those representing men or women have ob¬ tained the name of anthropomorphous. Agates may be stained artificially with solution of silver in spirit of nitre, and afterwards exposing the part to the 2 H 242 Agate II Asrathocles A G A sun ; and though these artificial colours disappear on laying the stone for a night in aquafortis, yet a knowledge of the practicability of thus staining agates must render these curious figures above mentioned strongly suspected of being the work, not of nature, but of art. Some account for these phenomena from natural causes. Thus Kircher, who had seen a stone of this kind in which were depicted the four letters usually inscribed on crucifixes, I. N. R. I. apprehends that some real crucifix had been buried under ground, among stones and other rubbish, where the in¬ scription happening to be parted from the cross, and to be received among a soft mould or clay susceptible of the impression of the letters, came afterwards to be petrified. In the same manner he supposes the agate of Pyrrhus to have been formed. Others resolve much of the wonder into fancy. The agate is used for making cups, rings, seals, handles for knives and forks, hilts for swords and hangers, beads to pray with, smelling-boxes, patch-boxes, &c. being cut or sawed with no great difficulty. Agate, among Antiquaries, denotes a stone of this kind engraven by art. In this sense, agates make a species of antique gems, in the workmanship whereof we find emi¬ nent proofs of the great skill and dexterity of the sculp¬ tors. Several agates of exquisite beauty are preserved in the cabinets of the curious ; but the facts or histories repre¬ sented on these antique agates, however well executed, are now become so obscure, and their explications so difficult, that several diverting mistakes and disputes have arisen among those who undertook to give their true meaning. Agate is also the name of an instrument used by gold- wire drawers; so called from the agate in the middle of it, which forms its principal part. AGATHA, St, a market town on the Austrian princi¬ pality of the Siebenbirgen, situated on the river Hartbache, with one Greek and one Lutheran church. The people are employed as coopers, shoemakers, and hosiers. Agatha, Santa, a town on the banks of a small river in the province Calabria Ulteriore, in the kingdom of Naples, with a castle, and 1127 inhabitants. AGATHIAS, or, as he calls himself in his epigrams, Agathius, distinguished by the title of Scholasticus, a Greek historian in the sixth century, in the reign of Justi¬ nian. He was born at Myrina, a colony of the ancient iEolians, in Asia the Less, at the mouth of the river Phy- thicus. He was an advocate at Smyrna. Though he had a taste for poetry, he was yet more famous for his history, which begins with the 26th year of Justinian’s reign, where Procopius ends. It was printed in Greek and Latin by Vulcanius, at Leyden, 1594, in 4to ; and at Paris, at the king’s printing house, 1660, in folio. AGATHO, the Athenian, a tragic and comic poet, was the disciple of Prodicus and Socrates, and applauded by Plato, in his Dialogues, for his virtue and beauty. His first tragedy obtained the prize; and he was crowned, in the presence of upwards of 30,000 persons, in the fourth year of the 90th Olympiad. There is nothing now extant of his works, excepting a few quotations in Aristotle, Athengeus, and others. AGATHOCLES, the famous tyrant of Sicily, was the son of a potter at Reggio. He was a thief, a common soldier, a centurion, a general, and a pirate, all in regular succession. He defeated the Carthaginians several times in Sicily, and was once defeated himself. He first made himself tyrant of Syracuse, and then of all Sicily; after which he vanquished the Carthaginians again both in Sicily and Africa. But at length having ill success, and being in arrears with his soldiers, they mutinied, forced him to fly his camp, and cut the throats of his children, AGE whom he left behind. Recovering himself, he relievedAgL Corfu, besieged by Cassander; burnt the Macedonian * fleet; and murdered the wives and children of those who had murdered his. Afterwards meeting with the soldiers^ themselves, he put them all to the sword; and ravaging the sea-coast of Italy, took the city of Hipponium. He was at length poisoned by his grandson Archagathus, in the 72d year of his age, 290 years before Christ, having reigned 28 years. AGATHYRNA or Agathyrnum, Agathyrsa or Agathyrsum, in Ancient Geography, a town of Sicily, now St Marco, as old as the war of Troy, having been built by Agathyrnus, son of TEolus, on an eminence. The gentilitious name is Agathynueus; or, according to the Roman idiom, Agathyrnensis. AGDE, a city of France, in the department of Herault It is seated on the river Herault, a mile and a quarter from its mouth, where it falls into the Gulf of Lyons, and where there is a fort built to guard Its entrance. The greater part of the inhabitants are merchants or seamen. The city is extended along the river, where it forms a little port wherein small craft may enter. AGE, in the most general sense of the word, signifies the duration of any being, from its first coming into ex¬ istence to the time of speaking of it,, if it still continues; or to its destruction, if it has ceased to exist some time before we happen to mention it. Among the ancient poets this word was used for the space of 30 years ; in which sense age amounts to much the same with generation. Thus, Nestor is said to have lived three ages when he was 90 years old. By ancient Greek historians, the time elapsed since the beginning of the world is divided into three periods, which they call ages. The first reaches from the creation to the deluge which happened in Greece during the reign of Ogyges: this they call the obscure or uncertain age, because the history of mankind is altogether uncertain during that period. The second they call the fabulous or heroic age, because it is the period in which the fabulous exploits ol their gods and heroes are said to have been performed. It began with the Ogygian deluge, and continued to the first Olympiad, when the third or historical age commenced. This division, however, it must be observed, holds good only with regard to the Greeks and Romans, who had no histories earlier than the first Olympiad. The Jews, Egyp¬ tians, Phoenicians, and Chaldees, not to mention the In¬ dians and Chinese, who pretend to much higher antiquity, are not*included in it. ,,i cy- * The interval since the first formation of man has been divided by the poets into four ages, distinguished by the epithets of golden, silver, brazen, and iron. During the golden age, Saturn reigned in heaven, and justice and in¬ nocence in this lower world. The earth then yielded her productions without culture ; men held all things in com¬ mon, and lived in perfect friendship. This period is sup¬ posed to have lasted till the expulsion of Saturn from his kingdom. The silver age commenced when men began to deviate from the paths of virtue, and, in consequence of this deviation, their lives became less happy* l‘'e brazen age commenced on a further deviation; and t ie iron age took place in consequence of one still greater. A late author, however, reflecting on the barbarism of tie first ages, will have the order which the poets assign the four ages inverted ; the first being a time of rudeness and ignorance, more properly denominated an iron than a golden age. When cities and states were founded, silver age commenced; and since arts and sciences, navi gation and commerce, have been cultivated, the golden age has taken place. c.y vdl jr r c : li J * AGE Aji In some ancient northern monuments, the rocky or stony age corresponds to the brazen age of the Greeks. It is AGE Agefefth. caiied rocky, on account of Noah’s ark, which rested on Mount Ararat; whence men were said to be descended or sprung from mountains ; or from Deucalion and Pyrrha restoring the race of mankind, by throwing stones over their heads. The northern poets also style the fourth age of the world the ashen age, from a Gothic king, Madenis or Mannus, who, on account of his great strength, was said to be made of ash, or because in his time people began to make use of weapons made of that wood. Among the Jews, the duration of the world is also divid¬ ed into three ages: 1. The seculum inane, or void age, was the space of time from the creation to Moses; 2. The present age denotes all the space of time from Moses to the coming of the Messiah; and 3. The age to come de¬ notes the time from the coming of the Messiah to the end of the world. Various other divisions of the duration of the world into ages have been made by historians. The Sibylline oracles, written, according to some, by Jews acquainted with the prophecies of the Old Testament, divide the du¬ ration of the world into ten ages ; and according to Jose¬ phus, each age contained six hundred years. It appears, by Virgil’s fourth eclogue, and other testimonies, that the age of Augustus was reputed the end of those ten ages, consequently as the period of the world’s duration. By some, the space of time commencing from Constan¬ tine, and ending with the taking of Constantinople by the Turks in the fifteenth century, is called the middle age ; but others choose rather to date the middle age from the division of the'empire made by Theodosius at the close of the fourth century, and extend it to the time of the em¬ peror Maximilian I. in the beginning of the sixteenth cen¬ tury, when the empire was first divided into circles. The middle is by some denoted the barbarous age, and the lat¬ ter part of it the lowest age. Some divide it into the non- acaxkmical and academical ages. The first includes the space of time from the sixth to the ninth century, during which schools or academies were lost in Europe ; the second, from the ninth century, when schools were restored, and universities established, chiefly by the care of Charle¬ magne. ‘ - r ■; 0 The several ages of the world may be reduced to three grand epochs, viz. the age of the law of nature, called by the Jews void age, from Adam to Moses ; the age of the Jewish law, from Moses to Christ; and the age of grace, from Christ to the present time. Age is also frequently used in the same sense with cen¬ tury, to denominate a duration of 100 years. Age likewise signifies a certain period of the duration of human life; by some divided into four stages, namely, infancy, youth, manhood, and old age; the first extending to the 15th year, the second to the 25th, the third to the 50th, and the fourth to the end oflife; by others divided mto infancy;'childhood, youth, manhood, and old age. Age, m Law, Signifies a certain period of life when per¬ sons of both sbxes are enabled to do certain acts. Thus, one at twelve years of age ought to take the oaths of alle¬ giance to the king in a leet; at fourteen he may marry, ciioose his guardian, and claim his lands held in soccage. wenty-one is called/«// age, a man or woman being then capable of acting for themselves, of managing their affairs, Ar ei disPosing of their estates, and the like. AixhLNOTH, Egelnoth, or AEthelnoth, in Latin Aehelnotus, ‘krchbishop of Canterbury in the reign of vJ,U!ao!r ^e.at’ succeeded Livingus in that see in the Furl a m ^ 118 P^utCv surnanied the Good, was son of gilmer, and at the time of his election, dean of Canterbury. After his promotion he went to Rome, and received his pall from Pope Benedict VIII. On his way thither as he passed through Pavia, he purchased, for a hundred talents of silver and one of gold, St Augustin’s arm, which was kept there as a relic, and sent it over to England as a present to Leofric, earl of Coventry. Upon his re¬ turn, he is said to have raised the see of Canterbury to its former lustre. He was much in favour with King Canute, and employed his interest with that monarch to good pur¬ poses. It was by his advice that the king sent over large sums of money for the support of the foreign churches ; and Malmesbury observes, that this prince was prompted' to acts of piety, and restrained from excesses, by the re¬ gard he had for the archbishop. Agelnoth, after he had sat 17 years in the see of Canterbury, departed this life on the 29th of October 1038, and was succeeded by Eadsius, King Harold’s chaplain. This archbishop was an author, having written, 1. A Panegyric on the blessed Virgin Mary; 2. A Letter to Earl Leofric concerning St Augustin ; 3. Letters to several persons. AGEMA, in Macedonian Antiquity, was a body of sol¬ diers, not unlike the Roman legion. AGEMOGLANS, Agiamoglans, or Azamoglans, in the Turkish Polity, are children purchased from the Tartars, or raised every third year, by way of tribute, from the Christians tolerated in the Turkish empire. These, after being circumcised and instructed in the re¬ ligion and language of their tyrannical masters, are taught the exercises of war, till they are of a proper age for carrying arms ; and from this corps the janizaries are re¬ cruited. With regard to those who are thought unfit for the army, they are employed in the lowest offices of the seraglio. Their appointments also are very small, not ex¬ ceeding seven aspers and a half per day, which amount to about threepence halfpenny of our money. AGEN, an arrondissement in the department of the Lot and Garonne, in the south-west of France, extending over 406 square miles, or 259,840 acres, containing 9 cantons and 93 communes, with 79,312 inhabitants. The chief city, of the same name, is situated on the left bank of the Garonne, and contains 10,800 inhabitants. AGENDA, among philosophers and divines, signifies the duties which a man lies under an obligation to per¬ form. Thus, we meet with the agenda of a Christian, or the duties he ought to perform; in opposition to the cre- denda, or things he is to believe. Agenda, among merchants, a term sometimes used for a memorandum-book, in which is set down all the busi¬ ness to be transacted during the day, either at home or abroad. _ Agenda, among ecclesiastical writers, denotes the ser¬ vice or office of the church. We meet with agenda ma- tutina et vespertina, the morning and evening prayers; agenda diei, the office of the day, whether feast or fast; agenda mortuorum, called also simply agenda, the service of the dead. Agenda is also applied to certain church-books, com¬ piled by public authority, prescribing the order and man¬ ner to be observed by the ministers and people in the principal ceremonies and devotions of the church; in which sense agenda amounts to the same with what is otherwise called ritual, liturgy, acalouthia, missal, formu¬ lary, directory, &c. AGENHINE, in our old writers, signifies a guest that has lodged at an inn for three nights, after which time he was accounted one of the family; and if he offended the king’s peace, his host was answerable for him. It is also written Hogenhine and Hogenhyne. AGENOIS, a country of France, in the department of 244 AGE Agenoria the Garonne, formerly the province of Guienne. It con- 11 tains about one hundred and twenty square leagues, is ^Agesilaus.^ fer^je an(j healthful, and, according to Caesar, was inhabit¬ ed by the Nitiobriges. It constituted part of the king¬ dom of Aquitania ; was held by the counts Of Toulouse, and successively by the English and French. AGENORIA, in Mythology, the goddess of courage and industry, as Vacuna was of indolence. AGENT, in a general sense, denotes any active power or cause. Agents are either natural or moral. Natural agents are such inanimate bodies as have a power to act upon other bodies in a certain and determinate manner; as gravity, fire, &c. Moral agents, on the contrary, are rational creatures, capable of regulating their actions by a certain rule. Agent is also used to denote a person intrusted with the management of an affair, whether belonging to a so¬ ciety, company, or private person. Agentes in Rebus, one of the ranks of officers in the court of the Constantinopolitan emperors, whose business was to collect and convey the corn both for the army and household ; to carry letters and messages from court to all parts of the empire; to regulate couriers and their ve¬ hicles ; to make frequent journeys and expeditions through the provinces, in order to inspect any motions, distur¬ bances, or machinations tending that way, and to give early notice thereof to the emperor. The agentes in rebus are by some made synonymous with our post-masters, but their functions were of great ex¬ tent. They correspond to what the Greeks call vrigoyogot, and the Latins veredarii. AGER, in Roman Antiquity, a certain portion of land allowed to each citizen. AGER Picenus, or Picenum, in Ancient Geography, a territory of Italy, to the south-east of Umbria, reaching from the Appennines to the Adriatic. The people are called Picentes (Cicero, Livy), distinct from the Picentini on the Tuscan Sea, though called by Greek writers Tlaivrmi. This name is said to be derived from the bird pious, under whose conduct they removed from the Sa¬ bines, of whom they were a colony. AGESILAUS, king of the Lacedemonians, the son of Archidamus, was raised to the throne in opposition to the superior claim of his nephew Leotychides. As soon as he came to the throne, he advised the Lacedemonians to an¬ ticipate the king of Persia, who was making great prepara¬ tions for war, and to attack him in his own dominions. He was himself chosen for this expedition, and gained so many advantages over the enemy, that if the league which the Athenians and the Thebans formed against the Lace¬ demonians had not obliged him to return home, he would have carried his victorious arms into the very heart of the Persian empire. He gave up, however, all these triumphs readily, to come to the succour of his country, which he happily relieved by his victory over the allies in Bceotia. He obtained another near Corinth ; but, to his great mor¬ tification, the Thebans afterwards gained several over the Lacedemonians. These misfortunes at first raised a cla¬ mour against him. He had been sick during the first ad¬ vantages which the enemy gained ; but as soon as he was able to act in person, his valour and prudence prevented the Thebans from reaping the advantages of their victo¬ ries; so that it was generally believed, had he been in health at the beginning, the Lacedemonians would have sustained no losses, and that all would have been lost had it not been for his assistance. It cannot be denied but he loved war more than the interest of his country required; for if he could have lived in peace, he would have saved the Lacedemonians several losses, and they would not A G G have been engaged in many enterprises which in the end contributed much to weaken their power. He died in the third year of the 104th Olympiad, being the 84th year of his age and 41st of his reign, and was succeeded by his 11 s' son Archidamus. Agesilaus would never suffer any pic^ ture or sculpture to be made of him, and prohibited it also by his will. This he is supposed to have done from a con¬ sciousness of his own deformity ; for he was of a short sta¬ ture, and lame of one foot, so that strangers used to despise him at the first sight. Agesilaus was extremely fond of his children, and would often amuse himself by joining in their diversions. One day when he was surprised riding upon a stick with them, he said to a person who had seen him in this posture, “ Forbear talking of it till you are a father.” AGG A, or Aggonna, a British settlement on the Gold Coast of Guinea. It is situated under the meridian of London, in lat. 6. N. AGGER, in the ancient military art, a work of fortifica¬ tion, used both for the defence and the attack of towns, camps, &c.; in which sense it is the same with what was otherwise called vallum, and in later times aggestum; and, among the moderns, lines, sometimes cavaliers, ter- rasses, &c. The agger was usually a bank or elevation of earth or other matter, bound and supported with timber; having sometimes turrets on the top, wherein the work¬ men, engineers, and soldiery, were placed. It was also accompanied with a ditch, which served as its chief de¬ fence. The height of the agger was frequently equal to that of the wall of the place. Caesar tells us of one he made which was 30 feet high and 330 feet broad. Besides the use of aggers before towns, the generals used to fortify their camps with such works. Agger, in ancient writers, likewise denotes the middle part of a military road, raised into a ridge, with a gentle slope on either side, to make a drain for the water, and keep the way dry.—The term is also used for the whole road or military way. Where highways were to be made in low grounds, as between two hills, the Romans used to raise them above the adjacent land, so as to make them of a level with the hills. These banks they call¬ ed aggeres. Bergier mentions several in Gallia Belgica, which were thus raised, ten, fifteen, or twenty feet above ground. AGGERHUUS, one of the four provinces or sees into which the kingdom of Norway is divided. It extends over 32,790 square miles, with a population of no more than 394,605 inhabitants. It is a very mountainous but most romantic district, abounding in woods, rivers, cas¬ cades, and lakes, with some moderately fruitful spots in the narrow valleys. The climate is raw and cold, and the frosts usually continue till May. The corn is scarcely sufficient for the consumption, though fish and potatoes are extensively used as food. The chief trade is in deals, pitch, and tar, with some iron, butter, tallow, and hides. The inhabitants all speak the peculiar language of Nor¬ way, a dialect of the Teutonic mixed with the Celtic; and are all of the Lutheran confession, and have 307 parish churches and chapels. Aggerhuus, a bailiwick in the see of the same name, m Norway. It is in the middle of the see, near the lake of Christiana, and comprehends 2 cities, 5 market towns, 22 parishes, and 67,808 inhabitants. AGGERS-HERRED, a district of Christiansand and a diocese of Norway. It consists of three juridical places; namely, Ascher, West Barm, and Agger. AGGLUTINANTS, in Pharmacy, a general name for all medicines of a glutinous or viscid nature; which, by A G I _ acihering to the solids, were supposed to contribute to re- tic pair their loss. _ > < I 1 AGGREGATION, in Physics, a species of union, igiiK nt. whereby several things which have no natural dependence ^ or connection with one another are collected together, so as in some sense to constitute one. Thus, a heap of sand, or a mass of ruins, is a body by aggregation. AGHER, a town of Ireland, situated in the southern part of Ulster, not far from Clogher. aghrim, a town of Ireland, in the county of Wicklow and province of Leinster, situated about 31 miles south¬ west of Wicklow. Aghrim, in Galway, a small village, distant about 32 miles from Dublin, and rendered memorable by a decisive battle fought there and at Kilcommodon-hill on the 12th of July 1691, between General Ginkle and Monsieur St Ruth, the commanders under King William III. and James II.; when St Ruth, the general of the Irish army, with 7000 of his men, was slain, but of the English only 600. The victory was the more considerable, as the English army consisted of no more than 18,000 men ; whereas the Irish were computed at 20,000 foot and 5000 horse and dra¬ goons. They lost likewise nine pieces of brass cannon; all their ammunition, tents, and baggage ; and most of their small arms, which they threw away to expedite their flight; with 11 standards, and 32 pairs of colours. AGILITY, an aptitude of the several parts of the body to motion. The improving of agility was one of the chief objects of the institution of games and exercises. The athletae made particular profession of the science of culti¬ vating and improving agility. Agility of body is often supposed peculiar to some people ; yet it seems less owing to any thing peculiar in their frame and structure, than to practice. AGINCOURT, a village of the French Netherlands, situated in N. lat. 50. 35. E. long. 2. 10. famous on ac¬ count of the victory obtained by Henry Y. of England over the French. On the morning of Friday the memorable 25th of Octo¬ ber, a. n. 1415, the day of Crispin and Crispianus, the English and French armies were ranged in order of battle, each in three lines, with bodies of cavalry on each wing. The constable D’Albert, who commanded the French army, fell into the snare that was laid for him, by drawing up his army in the narrow plain between the two woods. This deprived him, in a great measure, of the ad¬ vantage he should have derived from the prodigious supe¬ riority of his numbers; obliged him to make his lines un¬ necessarily deep, about 30 men in file ; to crowd his troops, particularly his cavalry, so close together, that they could hardly move or use their arms; and, in a word, was the chief cause of all the disasters that followed. The French, it is said, had a considerable number of cannon of differ¬ ent sizes in the field; but we do not hear that they did any execution, probably for want of room. The first line of the French army, which consisted of 8000 men-at-arms on foot, mixed with 4000 archers, with 500 men-at-arms mounted on each wing, was commanded by the constable D Albert, the dukes of Orleans and Bourbon, and many other nobles; the dukes of Alen^on, Brabant, and Bar, &c. conducted the second line; and the earls of Marie, Damartine, Fauconberg, &c. were at the head of the third line. The king of England employed various arts to sup¬ ply his defect of numbers. He placed 200 of his best archers in ambush, in a low meadow, on the flank of the first line of the French. His owm first line consisted wholly of archers, four in file ; each of whom, besides his bow and arrows, had a battle-axe, a sword, and a stake pointed with iron at both ends, which he fixed before him A G I 245 in the ground, the point inclining outwards, to protect him Agincourt from cavalry. This was a new invention, and had a happy 11 effect. That he might not be encumbered, he dismissed ASis- all his prisoners on their word of honour to surrender themselves at Calais if he obtained the victory, and lodged all his baggage in the village of Agincourt, in his rear, under a slender guard. The command of the first line was, at his earnest request, committed to Edward duke of York, assisted by the lords Beaumont, Willough¬ by, and Fanhope ; the second was conducted by the king, with his youngest brother Humphrey duke of Gloucester, the earls of Oxford, Marshal, and Suffolk; and the third was led by the duke of Exeter, the king’s uncle. The lines being formed, the king, in shining armour, with a crown of gold adorned with precious stones on his helmet, mounted on a fine white horse, rode along them, and ad¬ dressed each corps with a cheerful countenance and ani¬ mating speeches. To inflame their resentment against their enemies, he told them that the French hacl deter¬ mined to cut off three fingers of the right hand of every prisoner; and to rouse their love of honour, he declar¬ ed, that every soldier in that army who behaved well should from henceforth be deemed a gentleman, and en¬ titled to bear coat armour. When the two armies were drawn up in this manner, they stood a considerable time gazing at one another in solemn silence. But the king, dreading that the French would discover the danger of their situation, and decline a battle, commanded the charge to be sounded, about ten o’clock in the forenoon. At that instant the first line of the English kneeled down and kissed the ground; and then starting up, discharged a flight of arrows, which did great execution among the crowded ranks of the French. Immediately after, upon a signal being given, the archers in ambush arose, and discharged their arrows on the flank of the French line, and threw it into some disorder. The battle now became general, and raged with uncommon fury. The English archers, having expended all their ar¬ rows, threw away their bows, and rushing forward, made dreadful havock with their swords and battle-axes. The first line of the enemy was by these means defeated, its leaders being either killed or taken prisoners. The second line, commanded by the duke D’Alenin (who had made a vow either to kill or take the king of England, or to perish in the attempt), now advanced to the charge, and was encountered by the second line of the English, con¬ ducted by the king. This conflict was more close and furious than the former. The duke of Gloucester, wound¬ ed and unhorsed, was protected by his royal brother till he was carried off the field. The duke D’Alen^on forced his way to the king, and assaulted him with great fury; but that prince brought him to the ground, where he was instantly dispatched. Discouraged by this disaster, the second line made no more resistance, and the third fled without striking a blow ; yielding a complete and glorious victory to the English, after a violent struggle of three hours’ duration. AGIO, in Commerce, is a term chiefly used in Holland, and at Venice, to signify the difference between the value of bank stock and the current coin. AGIOSYMANDRUM, a wooden instrument used by the Greek and other churches, under the dominion of the Turks, to call together assemblies of the people. The agiosymandrum was introduced in the place of bells, which the Turks prohibited their Christian subjects the use of, lest they should make them subservient to sedition. AGIS, king of Lacedemon, was descended from Age- silaus II. in a right line. He projected the reformation of his kingdom, by the restoring of the laws of Lycurgus ; 246 A G I A G L Agis. but he fell under the weight of an enterprise that could not but be disagreeable to all those who had great posses¬ sions, and had been long accustomed to the sweets of a voluptuous life. Agis, being in the flower of his age, and having a very refined desire of glory, practised the ancient discipline first in his own person. His clothes and his table were according to the manners of former times; which is so much the more to be admired, because Agesistrata, his mother, and Acchidamia,his grandmother,had brought him up voluptuously. When he sounded the people’s minds, he found that the younger sort opposed his project less than those who had enjoyed a relaxation of discipline several years. The greatest difficulty was expected to arise from the women. They had at that time more credit than ever; for their power is never greater than when luxury is in fashion. Agis’s mother did not at all relish the proposed reformation. She must have lost her riches, which gave her a share in a thousand sorts of intrigues ; so she opposed the design at once, and treated it as a chimera. But her brother Agesilaus, whom Agis had en¬ gaged in his interests, knew how to manage her in such a manner, that she promised to second the enterprise. She endeavoured to gain the women ; but instead of suffering themselves to be persuaded, they applied to Leonidas, the other king of Lacedemon, and humbly besought him to frustrate the designs of his colleague. Leonidas durst not oppose it openly, for fear of irritating the people, to whom the reformation was -agreeable, because they found their account in it. He contented himself with countermining it by intrigues, and sowing suspicions as if Agis had as¬ pired to tyranny, by pulling down the rich and raising the poor. Agis did not fail to propose his new laws to the senate, relating to the discharge of debts, and a new divi¬ sion of the lands. Leonidas, being supported by the rich, opposed this project so strongly that there was one voice more against it than for it. He paid dear for his success in this affair. Lysander, one of the ephori, who had been the grand promoter of the reformation, caused certain accusations to be preferred against him ; using, at the same time, some expedients to make him an object of superstitious dislike. Leonidas, being frightened, took refuge in the temple of Minerva. He was summoned, and because he did not appear, he was degraded from his dignity, which was conferred on his son-in-law Cleom- brotus. He obtained leave to retire to Tegaea. The new ephori had Lysander and Mandroclidas tried for innova¬ tion : these persuaded the two kings to unite and turn out these ephori. The thing was brought about, but not without a great tumult in the city. Agesilaus, one of the ephori that succeeded those that were just turned out, would have caused Leonidas to be killed on the way to Tegasa, if Agis had not sent him a strong guard. The re¬ formation might then have been established, if Agesilaus had not found means to elude the good intentions of the two kings. Whilst this was transacting, the Achaians asked assistance, which was given them; and Agis had the command of the troops. He acquired a good deal of reputation in this campaign. At his return, he found his affairs so embroiled by the ill conduct of Agesilaus, that it was impossible for him to maintain himself. Leonidas was recalled to Lacedemon : Agis retired into one temple, and Cleombrotus into another. The wife of the latter be¬ haved herself in such a manner that she became the ad¬ miration of every body. Leonidas was contented with banishing his son-in-law; after which he applied himself entirely to the ruin of Agis. One of the ephori, who had no mind to return what Agesistrata, the mother of Agis, had lent him, was the principal instrument of the misfor¬ tune of this family. Agis never went out of his sanctuary i bathe. One day, as he was returning from thence a temple, he was seized by that ephorus and carrier]A ^ but to to the lempit:, nu was sciz-cu uy uiai epnorus and carried to prison. Then he was brought to his trial, condemned to i death* and delivered to the executioner. His mother andSX; grandmother used all the entreaty and importunity ima- ^ ginable, that, as he was king of Lacedemon, he might at least be permitted to plead his cause before the people But they were apprehensive lest his words would make too great an impression, and therefore they ordered him to be strangled that very hour. The ephorus who was in debt to Agesistrata permitted that princess to go into the prison - which he granted likewise to Agis’s grandmother: but he gave orders to strangle them one after another. Agesis¬ trata died in a manner that was extremely to her honour The wife of Agis, who was a princess of great fortune and prudence, was forced away from her apartment by King Leonidas, and obliged to marry his son Cleomenes who was then very young. AGISTMENT, Agistage, or Agistation, in Law the taking in of other people’s cattle to graze at so much per week. The term is peculiarly used for the taking of cattle to feed in the king’s forests, as well as for the profits arising from that practice. It is also used, in a metapho¬ rical sense, for any tax, burden, or charge ; thus, the tax levied for repairing the banks of Romney Marsh was call¬ ed agistamentum. AGISTOR or Agistator, an officer belonging to forests, who has the care of cattle taken in to be grazed, and levies the moneys due on that account. They are generally called quest-takers or gift-takers, and are created by letters patent. Each royal forest has four agistors. AGITATION, the act of shaking a body, or tossing it backwards and forwards. Agitation, in Physic, is often used for an intestine ‘commotion of the parts of a natural body. Fermentation and effervescence are attended with a brisk agitation of the particles. Agitation is one of the chief causes or instruments of mixtion ; by the agitation of the parts of the blood and chyle, in their continual circulation, sanguification is in a good measure effected. Butter is made out of milk by the same means ; in which operation a separation is made of the oleous parts from the serous, and a conjunction of the oleous together. Digestion itself is only supposed to be an insensible kind of agitation. Agitation is reputed one of the symptoms of inspira¬ tion. Petit informs us,1 that in the last century there11 ft arose in a church of Italy, for the space of a year, a pour of an extraordinary kind, which put all the people into trembling and agitations, and, unless they got away betimes, set them a dancing, with strange contortions and gesticulations. This seems to verify what has been re¬ lated of the temple of Delphi. AGITATOR, in Antiquity, a term sometimes used for a charioteer, especially those who drove in the circus at the curule games. Agitators, in English History, certain officers set up in the army in 1647, to take care of its interests. Crom¬ well joined the agitators, only with a view to serve his own ends ; which being once accomplished, he found means to get them abolished. AGLAIA, the name of the youngest of the three Graces, espoused to Vulcan. , - AGLAR or Aquileja, a city of Austria, in the govern¬ ment of Laybach and Trieste, in the district of Quino. It was in ancient times of great extent and celebrity, but now contains only 1420 inhabitants. It is situated in a swampy spot on the banks of the river Anfora, and is very unhealthful.

AGLIONBY, John, an English divine, chaplain in or- A i ^dinary to King James I., was born in Cumberland, and ad- A(rn,, mitted a student at Oxford in 1583. He was a man of universal learning, and had a very considerable hand in tlie translation of the New Testament appointed by King James I. in 1604. He died in 1609. AGMEN, in Antiquity, properly denotes a Roman army in march; in which sense it stands contradistinguished from acies, which denoted the army in battle array; though, on some occasions, we find the two words used indifferently for each other. The Roman armies, in their inarches, were divided into primum ay men, answering to our van-guard; medium agmen, our main-guard; and pos- tremum agmen, the rear-guard. The order of their march was thus: after the first signal with the trumpets, &c. the tents were taken down, and the baggage packed up; at the second signal the baggage was to be loaded on the horses and carriages, and at the third signal they were to begin their march. First came the extraordinarii ; then the auxiliaries of the first wing, with their baggage ; and these were followed by the legions. The cavalry marched either on each side or behind AGNATE, in Law, any male relation by the father’s side. AGNEL, an ancient French gold coin, first struck un¬ der the reign of St Louis, worth about twelve sols six de- niers. The agnel is also called sometimes mouton dor, and agnel dor. The denomination is supposed to have arisen from the figure of a lamb (agnus) or sheep, struck on one side. AGNES, St, a large mining village in the county of Cornwall, 168 miles from London, and five from Truro. It is on a small rocky harbour, only accessible to fishing boats, on the Bristol Channel. It contained, in 1801, 4161 inhabitants ; in 1811, 4960; and in 1821, 5762. It is also the name of one of the Scilly Islands, on the coast of Cornwall. The soil is fertile, and tolerably cultivated ; but there is a great deficiency of water. A light-house on the island, about 50 feet in height, built on one of the loftiest hills, is an important object to seamen. Its exact posi¬ tion, as ascertained by the great trigonometrical survey, is in long. 6. 19. 23. W. and lat. 49. 53. 38. N. from Greenwich. The light is composed of Argand lamps, with reflectors, moving in a circular revolution, and pre¬ senting a bright and conspicuous light in every direction once a minute. To the westward of St Agnes is the Gillstone rock, on which Sir Cloudesley Shovel was lost in the Association ship of wrar in 1707. AGNESI, Maria Gaetana, an Italian lady, who may be justly pronounced one of the greatest wonders and ornaments of her sex, was born at Milan, on the 16th of May 1718. Our materials for an account of this celebrat¬ ed female are by no means so complete, nor in some in¬ teresting particulars so distinct, as we could have wished. Not having been able to procure her Eloge by Frisi,1 we have been obliged to content ourselves with some shorter notices, the most detailed of which is that contained in Mazzuchelli’s History of the Writers of Italy, a work pub¬ lished during the earlier but more brilliant period of her life. The accounts which this writer and some others have given of the intellectual capacities and endowments which she displayed in early youth, call to mind the wonders which have been related of Picus of Mirandula and the Admirable Crichton; nor does there seem any reason to doubt their authenticity. At nine years of age A G N 247 she not only spoke the Latin language with precision, but Agnesi, even composed and delivered an oration in that lano-ua^e intended to prove that the cultivation of letters is not In¬ compatible with the female character. This singular piece was published at Milan the same year in which it was spoken, with the following title : Oratio, qua ostendi- tur artium liberalium studia a foemineo sexu neutiquam cth- horrere, hahita a Maria de Agnesiis, rhetoricce operam dante, anno retatis suae nono nondum exacto, die 18 Augusti 1727. At eleven years of age she spoke Greek with all the fluency of her native tongue. When yet very young, she had also acquired some of the languages of the East; and, in a word, her acquisitions as a linguist were such as to procure for her the appellation of a Walking Polyglot. But her aptitude for acquiring languages, however great, was by no means the only, or the most striking feature of her intellectual character. We have seen how early she essayed the discussion of a general question affecting the mental capacities of her sex; and the vigour and acute¬ ness displayed in this aspiring essay were, ere long, exert¬ ed with ardour and success in scientific inquiries. Flaving gone through the elementary branches of mathematics, she proceeded with alacrity to the study of natural philo- sophy; and she seems also to have carried her researches into the obscurer regions of metaphysical speculation. About the time when she reached her fifteenth year, her father formed a select assembly of the learned of Milan ; and at these meetings, which were held in his house, at stated times, for several years, Agnesi maintained a suc¬ cession of Theses on various points of speculation and philo¬ sophy. The ability which she displayed on these occasions seems to have been altogether surprising; and the effect was not the less, that her person was agreeable, and her whole deportment gentle and prepossessing. We are in¬ debted to the learned president De Brosses for the fol¬ lowing account of one of these conferences, at which he assisted during his travels in Italy, through the introduc¬ tion of Count Belloni. “ I had conceived,” says he, “ when I went to this conversazione, that it was only to talk with this young lady in the usual way, though on learned sub¬ jects ; but to my surprise Belloni addressed her in a fine Latin harangue, with all the formality of an academic ora¬ tion. She replied in the same language with promptness and ability ; and they proceeded, still in Latin, to discuss the origin of fountains, and the causes of the ebbings and flowings observed in some of them. She spoke like an angel on this subject, and I never heard it treated so much to my satisfaction. We then discoursed with her concern¬ ing the manner in which the soul receives impressions from outward objects, and their conveyance to the general sensorium, the brain; and afterwards upon the propagation of light, and the prismatic colours. The conversation afterwards became general, every one speaking to her in the language of his own country, and she answering in the same.” (Lettres sur VItalic, tom. i. p. 243.) But Agnesi seems to have taken but little delight in the glory which she acquired as a philosophical disputant. Her temper was retired and devout, and she appears to have acted this part more to gratify her father than herself. About her twentieth year she accordingly withdrew from these assemblies, and for a long period devoted the greater part of her time to mathematical studies. The Theses which she had maintained with so much applause were published in a quarto volume, under the following title: Proposi- tiones Philosophicce,'quas crebris disputationibus domi hahi- 1 Tliis Eloge has been translated into French by Boulard, and published both separately and at the end of a work entitled Bieiu foiti de la Religion Chretimnc, 1807, 2 vols.

The first fruit of her mathematical studies was a Com¬ mentary on the Conic Sections ot the Marquis de I’Hopital; but this piece she would never consent to publish, though Mazzuchelli says that it was greatly praised by many who had perused the manuscript. In the course of a few years, however, she gave to the world a mathematical work, which must ever secure her a high rank among the most distinguished cultivators of abstract science. This work, entitled Instituzioni Analitiche ad uso della Gioventu Italiana, was published at Milan in 1748, in two volumes quarto. The first volume treats of the analysis of finite quantities; the second, of the analysis of infinitesimals. These two volumes contain a full and satisfactory view of this branch of mathematical science in the state at which it had then arrived; and though improvements have since that time been introduced, the treatise of Agnesi, according to a very competent authority, may still be regarded as perhaps the best introduction that is to be found to the works of Euler and the other ma¬ thematicians of th.e Continent. (Edinb. Review, vol. iii. p. 408.) An English translation of this work was long ago executed by the late Professor Colson of Cambridge ; but the manuscript lay buried in obscurity for many years, and was only published in 1801, through the care and at the expense of Baron Maseres. Besides other literary honours which followed the pub¬ lication of the Analytical Institutions, Agnesi was, in 1750, appointed professor of mathematics and natural philosophy in the university of Bologna. The appoint¬ ment of a young female, of thirty-two years of age, to such a charge, must appear to many as not a little singular; but the truth is, that female professors were by no means un¬ common in Italy; and Lalande mentions several as hav¬ ing been eminent in the same university, one of whom was professor of anatomy. ( Voyage en Italic, tom. ii.) Our scanty information does not enable us to state whether Agnesi ever entered upon the active duties of the mathe¬ matical chair. Though her life was long, we can add but little in regard to her after-history. She died, according to the meagre notice contained in the Biographic Univer- selle, in the year 1799. Her mistaken notions of religious duty rendered the greater part of her existence but a blank to the world. She had early expressed a wish to retire into a convent, and seems to have carried this design into effect not long after the period when her great work pro¬ cured for her the honour's to which we have just alluded. We afterwards hear of her only as a devoted sister of the austere order of Blue Nuns, repelling the approaches of those of the learned who still desired to converse with her, and thus exhibiting another melancholy instance of the inconsistencies of our nature, and the darkening power of superstition over the brightest minds. But she lived long enough for the world to vindicate the intellectual capaci¬ ties of her sex,—to show that the female mind is not only fitted for the lighter exercises of literature, but capable also of fathoming the depths and unravelling the intricacies of abstract science. If there are any, therefore, whose speculations may have led them to more depreciating con¬ clusions, let them, to use the words of a profound and eloquent writer already quoted in this article, “ peruse the long series of demonstrations which the author of the Analytical Institutions has contrived with so much skill, and explained with such elegance and perspicuity: if they are able to do so, they will probably retract their former opinions ; if unable, they will not of course see the reasons for admiring her genius that others do ; but they may at AGO least learn to think modestly of their own.” (Edinb, Her vol. iii. p. 410.) ’ AGNO, a river of Naples, which, taking its rise in the a mountains of Terra di Lavora, falls into the Mediterranean ^ about seven miles north of Puzzuoli. AGNOETiE (from ayvoeu, to be ignorant of), in church history, a sect of ancient heretics, who maintained that Christ, considered as to his human nature, was ignorant of certain things, and particularly of the time of the day of judgment. Eulogius, patriarch of Alexandria, ascribes this heresy to certain solitaries in the neighbourhood of Jerusalem, who built their opinion upon the text, Mark xiii. 32, “ Of that day and hour knoweth no man, no not the angels who are in heaven, neither the Son, but the Father only.” The same passage was made use of by the Arians ; and hence the orthodox divines of those days were induced to give various explications thereof. Some allege that our Saviour here had no regard to his divine nature but only spoke of his human. Others understand it thus: that the knowledge of the day of judgment does not con¬ cern our Saviour considered in his quality of Messiah but of God. AGNOMEN, in Roman Antiquity, a kind of fourth or honorary name, given to a person on account of some extraordinary action, virtue, or other accomplishments. Thus the agnomen Africanus was bestowed upon Publius Cornelius Scipio on account of his great achievements in Africa.—The agnomen was the third in order of the three Roman names : thus, in Marcus Tullius Cicero, Marcus is the praenomen, Tullius the nomen, and Cicero the agnomen. AGNONE, a city at the foot of Monte Capraro, in the province Abruzzo Citeriore, in the kingdom of Naples, with 6000 inhabitants, who prepare many copper wares. AGNUS Dei, in the church of Rome, a cake of wax stamped with the figure of a lamb supporting the banner of the cross. These being consecrated by the pope with great solemnity, and distributed among the people, are supposed to have great virtues; as, to preserve those who carry them worthily, and with faith, from all manner of accidents; to expel evil spirits, &c. The name literally signifies Lamb of God; this being supposed an image or representation of the Lamb of God who took away the sins of the world. They cover it up with a piece of stuff cut in the form of a heart, and carry it very devoutly in their processions. Agnus Dei is also a popular name for that part of the mass wherein the priest, striking his breast three times, rehearses, with a loud voice, a prayer beginning with the words Agnus Dei. It is said to have been first brought into the missal by Pope Sergius I. AGOGE, among ancient musicians, a species of modu¬ lation, wherein the notes proceed by continuous degrees. AGON, a town of Sweden, in the province of Gefleborgs- land, with a good harbour in the Gulf of Finland. Agon, among the ancients, implied any dispute or con¬ test, whether it had regard to bodily exercises or the ac¬ complishments of the mind; and therefore poets, musicians, painters, &c. had their agones, as well as the athletsc. Games of this kind were celebrated at most of the heathen festivals with great solemnity, either annually or at cer¬ tain periods of years. Among the latter were celebrated at Athens, the agon gymnicus, the agon Nemeus instituted by the Argives in the 53d Olympiad, and the agon Olym¬ pias instituted by Hercules 430 years before the first Olympiad.—The Romans also, in imitation of the Greeks, instituted contests of this kind. The emperor Aurelian established one under the name of agon solis, the contest of the sun ; Dioclesian another, which he called agon ca- pitolinus, which was celebrated every fourth year, after the A G R Aji)1 manner of the Olympic games. Hence the years, instead of lustra, are sometimes numbered by agones. Apt- Agon also signified one of the ministers employed in t-^'^the heathen sacrifices, and whose business it was to strike the victim. The name is supposed to have been derived from hence, that standing ready to give the stroke, he asked, Agon ? or Agone ? Shall I strike ? AGONALES, an epithet given to the Salii. AGONALIA, in Roman Antiquity, festivals celebrated in honour of Janus or the god Agonius, whom the Romans invoked before undertaking any affair of importance. AGONALIS Cmcus, now La Piazza Novona, a long, large, beautiful street in the heart of Rome, adorned with fountains, and the obelisk of Caracalla, still retaining the form of that circus. The reason of the name Agonalis is either unknown or doubtful. Ovid seems to derive it from the agones, or solemn games, there celebrated, sup¬ posed to have been the Ludi Apollinares, or Actiaci, in¬ stituted by Augustus ; whence the circus was called Apol- linaris; also Alexandrinus, from the emperor Alexander Severus, who either inclosed or repaired it. AGONISMA, in Antiquity, denotes the prize given to the victor in any combat or dispute. AGONISTARCHA, from ayw, combat, and a^og, chief, in Antiquity, seems to have been much the same with agonotheta ; though some suggest a difference, mak¬ ing it the office of the former to preside at and direct the private exercises of the athletae, which they went through by way of practice, before they made their appearance on the public theatres or amphitheatres. AGONISTICI, in Church History, a name given by Donatus to such of his disciples as he sent to fairs, mar¬ kets, and other public places, to propagate his doctrine ; for which reason they were also called Circutores, Cir- cclliones, Catropitce, Coropitce, and at Rome Montenses. They were called Agonistici, from the Greek ayuv, combat, in regard they were sent as it were to fight and subdue the people to their opinions. AGONIUM, in Roman Antiquity, was used for the day on which the rex sacrorum sacrificed a victim, as well as for the place where the games were celebrated, otherwise called agon. AGONOTHETA, or Agonothetes, in Grecian Anti¬ quity, was the president or superintendent of the sacred games; who not only defrayed the expense attending them, but inspected the manners and discipline of the athletae, and adjudged the prizes to the victors. AGONYCLITfE, or Agonyclites, in Church History, a sect of Christians, in the 7th century, who prayed always standing, as thinking it unlawful to kneel. AGOILEUS, in Heathen Antiquity, an appellation given to such deities as had statues in the market-places ; par¬ ticularly Mercury, whose statue was to be seen in almost every public place. AGORANOMUS, in Grecian Antiquity, a magistrate o Athens, who had the regulation of weights and measures, t le prices of provisions, &c.—The agoranomi, at Athens, were ten in number, five belonging to the city, and as many to the Piraeus ; though others make them 15 in all, o whom they assign 10 to the city. To these a certain to or tribute was paid by all who brought any thing to sell in the market. <= J 5 • a market town in the Austrian dominions, lIl ,Aa with 1825 inhabitants. It is in the government o emce, and in the delegation of Belluno, on the river on evolo. In its vicinity are mines of copper, lead, su P ur’. and vitriol, the preparation of which is the chief occupation of the people. AGRA, a province of Hindostan, chiefly situated be- VOL. II. J A G R tween the 25th and 28th degrees of N. lat. On the north 1VLb and in average breadth to be ~ j® foAowmg are the principal geographical and political divisions:—1. Agra district; 2. the Doab; 3. the district of Etaweh ; 4. the Furruckabad district; 5. Cal- pee, Gohud, and Gualior; 6. the Bhurtpoor territories • 7. Alvar or Machery; 8. the Alighur district. This province has an unequal surface. To the north-east of the Jumna the country is flat and open, and rather bare of tiees ; but to the south of the Chumbul, and also towards the western frontier, it rises into hills, and is interspersed with jungle. Owing to the elevation of the ground, it has for the greater part of the year a temperate climate. In summer, while the hot winds prevail, it is intensely hot, and the climate is unhealthful, especially among the hills. But these winds do not continue for any length of time; and in the winter months it is actually cold, especially during the night. The province is indifferently watered. The chief rivers are the Jumna, the Chumbul, and the Ganges, besides other streams of inferior note. Except in the vicinity of the large rivers, water is scarce for the purposes of irrigation. Rice, which requires an abundant supply of moisture, is not cultivated. The soil is parti¬ cularly adapted to the cultivation of indigo, cotton, and sugar, the production of which is annually increasing in the country under the jurisdiction of the British : in that which is still subject to the native chiefs, agriculture is in a backward state. There are no remarkable mineral pro¬ ductions in the province of Agra. The animals differ in no respect from those found in other parts of Hindostan; and the breed of horses is much esteemed. The prin¬ cipal article manufactured is coarse cotton cloth ; but no great quantity is exported. The most fertile part of the province is the Doab, or the territory included be¬ tween the Ganges and the Jumna, which exports indigo, sugar, and cotton. The country to the north-west of Agra, which is under the dominion of the native chiefs, being scantily supplied with water, is of a very inferior quality, and comparatively unproductive. This province is not nearly so populous as Bengal, Jaupore, and the more flourishing parts of the British territory. It does not con¬ tain above six millions of inhabitants, of whom the greater proportion live under the British jurisdiction ; the remain¬ der under Scindia and others of the native princes. The chief towns, besides Agra, the capital, are Alvar or Aloor, the capital of a native rajah; Bhurtpoor, one of the strongest fortresses in India, which the British carried by storm in 1826 ; Deeg, another strong fortress ; Mathura, Kanoje, Etaweh, Gualior, Gohud, Calpee, Narwar, and Furrucka¬ bad. The natives are in general a robust and handsome race of people, and consist of a mixture of Hindoos and Mahometans. The Hindoo religion and language are pre¬ dominant, although the country has been subject to the Mahometans since the thirteenth century. Agra, the capital of the preceding province, is situ¬ ated on the south-west side of the Jumna, from the banks of which it extends upward in a vast semicircle. It is a large, old, and ruinous city, with little to attract attention beyond that picturesque confusion of houses, balconies, and projecting roofs, common to all Indian towns. The houses consist of several stories, and the streets are so narrow as scarcely to admit a palanquin. The greater part of this once flourishing city is now a heap of ruins, and uninhabit¬ ed. It is still, however, estimated to contain 60,000 in¬ habitants ; and as its commerce improves, which it is likely to do, from the facilities which it affords to the trade of 2 I 249 Agra. 250 A G R A G R western Hindostan, its population is likely to increase also. Since 1818, indeed, in consequence of the tranquillity of the neighbouring province of Rajpootana or Ajmeer, the produce of the customs has continued progressively to in¬ crease. It has a fort, which is very large and ancient, and is surrounded with high walls and towers of red stone, of the hardness and colour of jasper, which command some noble views of the city, its neighbourhood, and the wind¬ ings of the Jumna. The fort has a ditch of great depth, and a double rampart, the inner one being of an enormous height, with bastions at regular distances. Agra is famed for some beautiful edifices, the most remarkable of which is the Jage-mahal, atomb erected by the emperor Shah Jehan, to the memory of Begum Novr-jehan, his beloved wife. Bishop Heber mentions, that after all he had heard of this celebrated mausoleum, its beauty rather exceeded than fell short of his expectations. It is of white marble, and is placed on an elevated terrace of white and yellow mar¬ ble, with four tall minarets of the same material rising at each of its angles. The interior, containing a central hall, in which are the tombs of the emperor and his wife, is re¬ markable for its exquisite finish ; the pavement being laid with alternate squares of marble, and the walls, screens, and tombs, crowned with flowers and inscriptions execut¬ ed in beautiful Mosaic of cornelian, lapis lazuli, and jas¬ per. The general effect of the whole is solemn and im¬ pressive rather than gaudy. There is a tomb erected to another of the emperors, now used as a court of justice, which is a splendid edifice. Agra contains, besides, a beautiful mosque of white marble, carved with exquisite simplicity and elegance, and the palace, built by Acbar chiefly of the same material, and now used as warehouses, offices, and lodging-rooms for the garrison. At Secundra, a ruinous village about six miles from Agra, is the magni¬ ficent tomb of the emperor Acbar, which, Bishop Heber remarks, is the most splendid building in its way that he had seen in India. Agra was greatly enlarged and embellished by Acbar, who made it his capital. The city, which was under the rule of Scindia, surrendered to the British army under Lord Lake in 1803. It was soon after made the seat of the civil establishment for the collection of the re¬ venue and the administration of justice. The fortifications have been lately strengthened and improved. 137 miles travelling distance from Delhi. Long. 77. 53. E. Lat. 27. 11.

For some learned and ingenious inquiries on this subject, see Niebuhr’s Roman History.

It was besieged by the Turks in 1552, with 70,000 men ; but they lost 8000 in one day, and were obliged to raise the siege, though the garrison consisted only of 2000 Hungarians, assisted by the women, who performed wonders on this occasion. However, it was afterwards taken by Mahomet III. in 1596, but was retaken by the emperor in 1687; since which time it has continued under the dominion of the house of Austria.

AGRICOLA, Cn^us Julius, born at Frejus, in Pro¬ vence, was in Vespasian’s time made lieutenant to Vet- tius Bolanus in Britain; and upon his return was ranked by that emperor among the patricians, and made governor of Aquitania. This post he held for three years ; and upon his return was chosen consul, and afterwards appointed governor of Britain, where he greatly distinguished him¬ self. He reformed many abuses occasioned by the ava¬ rice or negligence of former governors, put a stop to ex¬ tortion, and caused justice to be impartially administered. Vespasian dying about this time, his son Titus, knowing the great merit of Agricola, continued him in the govern¬ ment. In the spring he marched towards the north, where he made some new conquests, and ordered forts to be built for the Romans to winter in. He spent the fol¬ lowing winter in concerting schemes to bring the Britons to conform to the Roman customs. He thought the best way of diverting them from rising and taking arms was to soften their rough manners, by proposing to them new kinds of pleasure, and inspiring them with a desire of imi¬ tating the Roman manners. Soon after this the country was adorned with magnificent temples, porticoes, baths, and many other fine buildings. The British nobles had at length their sons educated in learning; and they who before had the utmost aversion to the Roman language, now began to study it with great assiduity. They wore likewise the Roman habit; and, as Tacitus observes, they were brought to consider those things as marks of polite¬ ness, which were only so many badges of slavery. Agri¬ cola, in his third campaign, advanced as far as the Tweed; and in his fourth he subdued the nations betwixt the Tweed and the friths of Edinburgh and Clyde, into which the rivers Glotta and Bodotria discharge themselves ; and here he built fortresses to shut up the nations yet uncon¬ quered. In his fifth he marched beyond the friths, where he made some new acquisitions, and fixed garrisons along the western coasts, over against Ireland. In his sixth lout Mia, V A G R , ola campaign he passed the river Bodotria; ordering his fleet, the first which the Romans ever had in those parts, to row along the coasts, and take a view of the northern parts. u1' jn the following spring, the Britons raised an army of 30,000 men; and the command was given to Galgacus, who, according to Tacitus, made an excellent speech to his countrymen on this occasion. Agricola likewise ad¬ dressed his men in very strong and eloquent terms. The Romans gained the victory, and 10,000 of the Britons are said to have been killed. This happened in the reign of the emperor Domitian, who, growing jealous of the glory of Agricola, recalled him, under pretence of making him governor of Syria. Agricola died soon after; and his death is suspected to have been occasioned by poison given him by that emperor. Tacitus the historian married his daughter, wrote his life, and laments his death in the most pathetic manner. Agricola, George, a German physician, famous for his skill in metals. He was born at Glaucha, in Misnia, on the 24th of March 1494. The discoveries which he made in the mountains of Bohemia gave him so great a desire of examining accurately into every thing relating to metals, that though he had engaged in the practice of physic at Joachimstal by advice of his friends, he still prosecuted his study of fossils with great assiduity, and at length re¬ moved to Chemnitz, where he entirely devoted himself to this study. He spent in pursuit of it the pension he had from Maurice duke of Saxony, and part of his own estate ; so that he reaped more reputation than profit from his la- A o R hours. He wrote several pieces upon this and other sub¬ jects ; and died at Chemnitz on the 21st of November 1555 a very firm Papist. In his younger years he seemed not averse to the Protestant doctrine; and he highly disap¬ proved of the scandalous traffic of indulgences, a^d seve¬ ral other things in the church of Rome. In the latter part of his life, however, he attacked the Protestant reli¬ gion, which rendered him so odious to the Lutherans, that they suffered his body to remain unburied for five days It was then removed from Chemnitz to Zeitz, where it was interred in the principal church. , Ag*ict?la> J°hn, a Saxon divine, born at Eisleben in 14J2. He went as chaplain to Count Mansfeld, when that nobleman attended the elector of Saxony to the diet at Spire in 1526, and that of Augsburg in 1530. He was of a restless, ambitious temper, rivalled and wrote against Melanchthon, and gave Count Mansfeld occasion to re¬ proach him severely. He obtained a professorship at Wittemberg, where he taught particular doctrines, and became founder of the sect of Antinomians; which occa¬ sioned warm disputes between him and Luther, who had before been his very good friend. But though he was never able to recover the favour either of the elector of Saxony or of Luther, he received some consolation from the fame he acquired at Berlin, where he became preach¬ er at court; and was chosen, in 1548, in conjunction with Julius Phlug and .Michael Heldingus, to compose the famous Interim, which made so much noise in the world. He died at Berlin in 1566. 251 Agricola II Agricul¬ ture. AGRICULTURE. TT is our principal object in this article to lay before our *- readers a view of the present state of British agri¬ culture, particularly as the art is practised in our best cultivated counties. Much of what we shall state is de¬ rived from our own experience and observation; but we shall nevertheless be careful, on all matters of importance, to refer to the most approved authorities. It is sufficiently evident that the culture of the soil must have somewhat preceded, and always kept pace with, the increase of population. When we read of the large armies brought into the field in the early ages, and the great number of inhabitants which some of the ancient cities are said to have contained, we must necessarily conclude that the labours of agriculture were conducted with skill, and that its produce was abundant. A con¬ siderable population may, no doubt, subsist upon a rich soil, even in a very rude state of the art, drawing from it only the supply of their own wants; but if much of the cultivator s time be required in the service of the public, and still more, if he has to provide for the subsistence and t ic luxury of large cities, he can obtain the necessary surplus produce only by successive improvements in his art. Not only his gross produce, but his net disposable produce, must be proportionally increased. But of the rural economy even of the most civilized nations of antiquity, we are almost wholly ignorant. From t ie age of Moses, almost down to the commencement of ie Christian era, though something may be gleaned from incidental notices in the Scriptures, and in the writings of a ew ancient authors, we are quite unacquainted with ie means by which food was obtained from the soil to support the rapid increase of mankind; especially when " l nd it accumulated on spots which seem to have been a ways naturally unproductive. We ought, perhaps, to except the W orks and Days of Hesiod, who lived in the tenth century before our era, and who has described at some length the labours and the products of the agri¬ culture of Greece at that early period. His work contains almost all the information we possess respecting the rural economy of that celebrated people. Among the Romans this art seems to have obtained a Am-icul- high degree of improvement. It was practised by the ture of "the rich and the great, and described by their poets and his-Romans, torians, several of whose works have reached our own times. These must be familiar to the classical scholar, and have been rendered accessible to all by Dickson, in his Husbandry of the Ancients, and other writers. We need therefore only mention the names 6f Cato, Varro, Virgil, Columella, Pliny, and Palladius, in the order in which they wrote. The treatises De Re Rustica of Varro and Columella are the most complete; but none of the Roman writers enables us to trace the rise and progress of agriculture, either in Italy or in any other country under their dominion. The most useful lesson they convey to the present age, perhaps, is the importance of attending to minute details, which their greatest names did not consi¬ der beneath their notice in the best period of their history. From the fall of the Roman empire till the revival ofAgricuI- learning in the fifteenth century, little is known of theture °f the state of agriculture in any part of Europe. The historians %U(lal of the period were too much occupied in recording mili-tlmes* tary achievements, and with the rude policy and intestine broils of their respective countries, to give much atten¬ tion to the peaceful, and at that time degraded, labours of the husbandman. The policy of the feudal system, the distribution of society which it occasioned, and the perpetual dissensions and petty hostilities which it en¬ gendered, furnish the best evidence of the low state of an art which can flourish only under the protection of law, and be carried on wdth success only by the energy of free 252 AGRICU Agricul- men. But, during this long interval, the population of ture. Europe was divided into two great classes, of which by —far the larger one was composed of bondmen, without property, or the power of acquiring it, and small tenants, very little superior to bondmen; and the other class, consisting chiefly of the great barons and their retainers, was more frequently employed in laying waste the fields of their rivals, than in improving their own. The super¬ stition of the times, which destined a large portion of the country to the support of the church, and which, in some measure, secured it from predatory incursions, was the principal source of what little skill and industry were then displayed in the cultivation of the soil. “ If we considei the ancient state of Europe,” says Mr Hume,1 “ we shall find, that the far greater part of society were everywhere bereaved of their personal liberty, and lived entirely at the will of their masters. Every one that was not noble was a slave ; the peasants were not in a better condition; even the gentry themselves were subjected to a long train of subordination under the greater barons, or chief vassals of the crown, who, though seemingly placed in a high state of splendour, yet, having but a slender protec¬ tion from law, were exposed to every tempest of the state, and, by the precarious condition on which they lived, paid dearly for the power of oppressing and tyran¬ nizing over their inferiors.”—“ The villains were entirely occupied in the cultivation of their master s land, and paid their rents either in corn or cattle, and other pro¬ duce of the farm, or in servile offices, which they per¬ formed about the baron’s family, and upon farms which he retained in his own possession. In proportion as agri¬ culture improved and money increased, it was found that these services, though extremely burdensome to the vil¬ lain, were of little advantage to the master; and that the produce of a large estate could be much more conveni¬ ently disposed of by the peasants themselves, who raised it, than by the landlord or his bailiff, who were formerly accustomed to receive it. A commutation was therefore made of rents for services, and of money-rents for those in kind; and as men in a subsequent age discovered that farms were better cultivated where the farmer enjoyed security in his possession, the practice of granting leases to the peasant began to prevail, which entirely broke the bonds of servitude, already much relaxed from the former practices. The latest laws which we find in England for enforcing or regulating this species of servitude were enacted in the reign of Henry VII. And though the an¬ cient statutes on this subject remain still unrepealed by Parliament, it appears, that before the end of Elizabeth, the distinction between villain and freeman was totally, though insensibly, abolished; and that no person remained in the state to whom the former laws could be applied.” Leases du- But, long before the fifteenth century, it is certain that ring the there was a class of tenants holding on leases for lives, or for a term of years, and paying a rent in land produce, in services, or in money. Whether they gradually sprung up from the class of bondmen, according to Lord Kames,2 or existed from the earliest period of the feudal constitu¬ tion, according to other writers,3 their number cannot be supposed to have been considerable during the middle ages. The stock which these tenants employed in culti¬ vation commonly belonged to the proprietor, who received a proportion of the produce as rent; a system which still exists in France and in other parts of the Continent, where such tenants are called metayers, and some vestiges of middle ages. L T U R E. which may yet be traced in the steel-bow of the law of U Scotland. Leases of the thirteenth century still remain n ’ and both the laws and chartularies3 clearly prove the^ j existence in Scotland of a class of cultivators distinct from the serfs or bondmen. Yet the condition of these tenants seems to have been very different from that of the tenants of the present day; and the lease approached nearer in its form to a feu charter than to the mutual agreement now in use. It was of the nature of a beneficiary grant by the proprietor, under certain conditions, and for a limited pe- riod: the consent of the tenant seems never to have been doubted. In the common expression, “ granting a lease,” we have retained an idea of the original character of the deed, even to the present time. The corn crops cultivated during this period seem to Crop have been of the same species, though all of them pro-hvat bably much inferior in quality to what they are in the present day. Wheat, the most valuable grain, must have borne a small proportion, at least in Britain, to that of other crops ; the remarkable fluctuation of price, its ex¬ treme scarcity, indicated by the extravagant rate at which it was sometimes sold, as well as the preparatory cultiva¬ tion required, may convince us that its consumption was confined to the higher orders, and that its growth was by no means extensive. Rye and oats furnished the bread and drink of the great body of the people of Europe. Cultivated herbage and roots were then unknown in the agriculture of Britain. It was not till the end of the reign of Henry VIII. that any sallads, carrots, or other edible roots were produced in England. The little of these vegetables that was used, was formerly imported from Holland and Flanders. Queen Catharine, when she wanted a sallad, was obliged to dispatch a messenger thither on purpose.6 The ignorance and insecurity of those ages, which ne¬ cessarily confined the cultivation of corn to a compara¬ tively small portion of country, left all the rest of it in a state of nature, to be depastured by the inferior animals, then only occasionally subjected to the care and control of man. Cultivators were crowded together in miserable hamlets ; the ground contiguous was kept continually un¬ der tillage ; and beyond this, wastes and woodlands of a much greater extent were appropriated to the mainten¬ ance of their flocks and herds, which pastured indiscrimin¬ ately, with little attention from their owners. The low price of butcher-meat, though it was then the food of the common people, when compared with the price of corn, has been justly noticed by several writers as a decisive proof of the small progress of civilisation and industry. According to the reports of a writer who has had ac-«P| f cess to the best sources of information, in addition to his^ , own observations, the present state of the agriculture of the^j P, greater part of the Continent of Europe is not very dif¬ ferent from what it was in Britain during the prevalence of the feudal system. “ The greater part of France, he says, “ a still much greater portion of Germany, and nearly the whole of Prussia, Austria, Poland, and Russia, present a wretched uniformity of system. It is called the three- course husbandry, consisting of, 1st, one year’s clean fal¬ low ; 2d, winter corn, chiefly rye, with a proportion ot wheat commensurate to the manure that can be applied , 3d, summer corn, or barley and oats. There are occasiona and small deviations from this system. In some few cases potatoes, in others peas, are grown, in the fallow year, 1 History of England, chap, xxiii. 3 Bell’s Treatise on Leases. * Chalmers’s Caledonia, book iv. c. 6. 2 Karnes’s Law Tracts. . 4 Sir John Cullum’s History and Antiquities of Hatestcd {Suffolk.) 6 Hume’s History of England, chap, xxiii. AGRICULTURE. 253 ^gy are only minute exceptions to the generally uin" established system. It is not surprising that under such ^/^a system the produce should not be much more than four times the quantity of seed, at which rate it is calcu¬ lated, as appears to be rightly, by Baron Alexander Hum- k°« The fields are almost universally uninclosed, and ex¬ posed to the most injurious effects of a changeable and an intemperate climate. The ancient feudal system of te¬ nure is still continued, modified indeed, and softened in gome few parts, but not to a degree or an extent that de¬ serves to be taken into account in the view now under consideration of the countries as a whole. The peasants, for the most part, are adstricti glebce. ; and where, by re¬ cent laws, their condition has been changed, the practical effect has yet hardly had time to exhibit any observable improvement in their state. Labour, whether of men or of cattle, is usually exchanged for the occupancy of land; and hence the labour is performed in the most negligent and imperfect manner, that the vigilance of an overseer, who cannot be everywhere present, will allow. u The lords of the soil, besides their demesnes, have the mht of pasturage on the fields of their tenants from har¬ vest to the next seed-time: hence none of those interven¬ ing crops which tend to enrich the soil can be cultivated without infringing on their rights. “ Among the cultivators of the land little or no accu¬ mulation of capital has been formed; from the lord to the lowest grade of the peasantry, all are alike destitute of disposable funds. The lords are only rich in land, and sufficiently at their ease, if that land be unencumbered with mortgages or annuities. The peasants, whether own¬ ers of the live stock and of the implements, or having the use of them with the land from its owners, are content to live on, from year to year, eating their own produce, growing their own wool and flax, and converting them into garments. They are quite satisfied if they can dis¬ pose of as much surplus produce as will pay the small share of money rent which becomes due to their lord.” {Tracts relating to the Corn Trade and Corn Laws, by William Jacob, Esq. 1828.) It is certain, howrever, that an improved system has been introduced, and is extending itself, though slowly, in many parts of the countries which this writer has mentioned. Public establishments have been formed, which afford ex¬ amples of correct management; and by these means know¬ ledge is diffused among the principal land-owners in the first instance, and must ere long descend to the cultivator. Since the peace, many of the former class have visited other countries, and particularly Great Britain, with a view to the improvement of their estates. Some of them have held out encouragement to settlers from this coun¬ try ; others carried back our best implements, with farm- bailiffs capable of instructing their people in the use of them, and of introducing our system of management ge¬ nerally ; and not a few individuals of rank and influence in most parts of the Continent of Europe are now well ac¬ quainted with our agriculture, by their own personal ob¬ servation. Prompted by interest, their active minds, no longer occupied in war, seem to enter eagerly upon this new field of employment. It is evident, indeed, from the great increase which has taken place of late in the population of these countries, as well as of our own, that a corresponding increase of produce must now be drawn from the soil. In all old peopled countries, the extension of tillage to fresh lands, without any improvement in the management, presents only a temporary and very limited resource. At present, however, we have certainly little to learn from the agriculture of other countries ; at least very little that can be beneficially introduced into our climate, which forbids any attempt at cultivating the fruits of the south of Europe. Even on a similar soil, and in the same lati¬ tude, the labours of the husbandman must be to a con¬ siderable extent directed and controlled by the local cir¬ cumstances in which he is placed. This, perhaps, is the principal reason why the old system of successive crops of corn still prevails so generally throughout the Continent. The demand for butcher-meat, for instance, may not be such as to afford a suitable return for the extended cul¬ ture of turnips and other ameliorating crops, which are found so beneficial in this country. We should except from this remark much of the Ne¬ therlands, and probably a part of Italy. Flanders has long been celebrated for its agriculture; and the care and suc¬ cess with which its labours are conducted seem not un¬ worthy the attention of our best cultivators. The culture of the Vale of Arno, in Italy, also presents an interesting object, and has been warmly eulogized by Chateauvieux and other travellers. But instead of going into details here, we shall notice, under the heads to which they be¬ long, the practices that appear to us of most importance in the agriculture of other countries, when we come to de¬ scribe our own. Before entering upon this our main object, it may not be without its interest to present a concise view of the progress of our agriculture to its present state, from the rude condi¬ tion in which, in common with that of the rest of Europe, it was found at the time when we first have authorities to refer to on the subject. Such a view must necessarily in¬ clude notices of the principal laws affecting it, as well as of our early writers, whose works are very little known; and it may serve to convey some idea of the successive changes that have occurred in the condition of the great body of our people. The subject of this article will thus be considered under two divisions. In the first, we shall treat of the history of British agriculture ; and in the second, of its present state ; describing under the latter the crops, culture, and general management adapted to different soils, agreeably to the practice of our best cultivators. Agricul¬ ture. Part I. History of British Agriculture. Of the early agriculture of England, and of the condi- Agricul- tion of its cultivators, we may form some conception by ture in adverting to a few of the enactments, from the Conquest down to the beginning of the reign of Henry VII. in 1485, tlie J when the feudal system, which had been gradually falling century. into decay, was almost dissolved in that country. One of the earliest and greatest grievances was the levying of Purveyance. This originally comprehended the necessary provisions, carriages, &c. which the nearest farmers were obliged to furnish to the king s armies at the current prices, and to his houses and castles in time of war. It was called the great purveyance, and the officers who collected those necessaries were called purveyors. The smaller purveyance included the necessary provisions and carriages for the king’s household, when living at home, or travelling through the kingdom, which the ten¬ ants on the king’s demesne lands were obliged to furnish gratis ; and the practice came to be adopted by the ba¬ rons and great men, in every tour which they thought proper to make in the country. These exactions were so grievous, and levied in so licentious a manner, that the farmers, when they heard of the court s approach, often deserted their houses, as if the country had been invaded 254 AGRICULTURE. Agricul- by an enemy. “ Purveyance,” says Dirom,1 “ was per- ture. haps for many centuries the chief obstruction to the ag- riculture and improvement of Great Britain. Many laws were made for the reformation and regulation of purvey¬ ance, but without effect; and the practice continued down to so late a period as the reign of James the First.” The home trade in corn was restrained by acts against forestallers in 1360, and at several subsequent periods. For many years after the Conquest, the greater part of the trade of England was carried on in markets and fairs; and a very considerable part of the revenue of the crown arose from the duties payable to the king, upon the goods brought to them for sale. The barons had also tolls at the fairs within their respective jurisdictions. When farmers v and merchants were bringing their corn and other neces¬ saries to be sold there, they were sometimes met on the way by persons who purchased their commodities, in order to retail them at a higher price. Thus the king and the lords of the manor lost the several duties payable to them; and the price, it was thought, was at the same time raised to the inhabitants. Such were the original forestallers, who were subjected by several statutes to severe penalties. This crime of forestalling, and the kindred ones of regrat¬ ing and engrossing, were carefully defined, and the dif¬ ferent degrees of punishment specified, in a new statute in 1552, to be afterwards noticed. An early law of 1266, for regulating the assize of bread and ale, furnishes a clear proof of the little intercourse that must have subsist¬ ed at that time between town and country. “ Brewers in cities,” says the statute, “ may well afford to sell two gallons of beer or ale for a penny, and out of cities three or four gallons for a penny.” Several laws were made in the fourteenth and fifteenth centuries, permitting the exportation of grain when the price of wheat did not exceed six shillings and eightpence a quarter; and in 1463 importation was prohibited when the price was lower. The last statute, however, was little attended to, and foreign grain was admitted as before; while the state of the country, and the restrictions on in¬ ternal commerce, scarcely permitted any advantage to be derived from the acts allowing exportation. Husban- In Mr Chalmers’s Caledonia, a great many valuable dry of notices are collected regarding the husbandry of Scotland Scotland, during these ages. It is evident from his elaborate re¬ searches, that the progress of cultivation in the 13th cen¬ tury had been greater than we should have expected from the turbulence of the times, and the comparatively rude and uncivilized state of society. Purveyance, and other obstructions to improvement, were nearly the same in Scotland as in England; the laws regarding the corn trade appear, in some instances, to have been copied from those of England ; and in the northern, as in the southern part of the island, the clergy were by far the most skilful and industrious husbandmen. Yet it is difficult to reconcile the idea of any consider¬ able improvement, particularly in so far as regards the extensive cultivation of wheat (which Mr Chalmers infers from the authorities he quotes), with an act passed in 1426, which ordained every husbandman tilling with a plough of eight oxen to sow at least a firlot (little more than a Winchester bushel) of wheat, and half a firlot of peas, with a proportion of beans ; or with the state of the districts only a few years ago, where wheat is said to have been extensively grown at that early period. By statute 1449, the tenant was for the first time se¬ cured in possession, during the term of his lease, against a purchaser of the land; and in 1469 he was protected A from having his property carried off for the landlord’s * debts, beyond the amount of rent actually due; an en- actment which proves his miserable condition before that time. Soon after the beginning of the 16th century, agri-tv culture partook of the general improvement which fol-on lowed the invention of printing, the revival of learning tur and the more settled authority of government; and in' stead of the occasional notices of historians, we can now refer to regular treatises, written by men who engaged eagerly in this neglected and hitherto degraded occupa¬ tion. We shall therefore give a short account of the prin¬ cipal works, as w^ell as of the laws and general policy of Britain, in regard to agriculture, from the early part of the sixteenth century to the Revolution in 1688, when a new era commenced in the legislation of corn, and soon after in the practice of the cultivator. e. 'v The first and by far the best of our early works is the Fit Book of Husbandry, printed in 1534, commonly ascribed ber to Fitzherbert, a judge of the common pleas in the reign of Henry VIIL This was followed, in 1539, by the Book of Surveying and Improvements, by the same author. In the former treatise we have a clear and minute descrip¬ tion of the rural practices of that period, and from the latter may be learned a good deal of the economy of the feudal system in its decline. The Book of Husbandry has scarcely been excelled by any later production, in as far as concerns the subjects of which it treats; for at that time cultivated herbage and edible roots were still un¬ known in England. The author writes from his own ex¬ perience of more than forty years ; and, with the excep¬ tion of passages denoting his belief in the superstition of the Roman wu-iters, there is very little of this valuable work that should be omitted, and not a great deal that need be added, in so. far as regards the culture of corn, in a manual of husbandry adapted even to the present time. Fitzherbert touches on almost every department of the art, and in about a hundred octavo pages has contrived to condense more practical information than will be found scattered through as many volumes of later times; and yet he is, minute even to the extreme on points of real utility. There is no reason to say, with Mr Harte, that he had revived the husbandry of the Romans ; he merely describes the practices of the age in which he lived; and from his commentary on the old statute extenta ma- nerii, in his Book of Surveying, in w hich he does not al¬ lude to any recent improvements, it is probable that the management which he details had been long established. But it may surprise some of the agriculturists of the pre¬ sent day to be told, that, after the lapse of almost three centuries, Fitzherbert’s practice, in some rrfaterial branches, has not been improved upon ; and that in several districts abuses still exist, which were as clearly pointed out by him at that early period as by any writer of the present age. The Book of Husbandry begins with the plough and other instruments, which are concisely and yet minutely described; and then about a third part of it is occupied with the several operations as they succeed one another throughout the year. Among other things in this part of the work, the following deserve notice:—“ Somme (ploughs) wyll tourn the sheld bredith at every landsende, and plowe all one way;” the same kind of plough that is now found so useful on hilly grounds. Of wheel-ploughs he observes, that “ they be good on even grounde that lyeth 1 Inquiry into the Corn Laws, &c. p. 9. AGRICULTURE. V ml- lyghte;” an^ on suc^ ^an(^s they are still most commonly ’ t e. employed. Cart-wheels were sometimes bound with iron, ^ ^of which he greatly approves. On the much agitated question about the employment of horses or oxen in la¬ bour, the most important arguments are distinctly stated. “ In somme places,” he says, “ a horse plough is better,” and in others an oxen plough, to which, upon the whole, he gives the preference; and to this, considering the practices of that period, they were probably entitled. Beans and peas seem to have been common crops. He mentions the different kinds of wheat, barley, and oats ; and after describing the method of harrowing “all maner of cornnes,” we find the roller employed. “ They use to role their barley grounde after a showr of rayne, to make the grounde even to mowe.” Under the article “ To falowe,” he ob¬ serves, “ the greater clottes (clods) the better wheate, for the clotfes kepe the wheat warme all wynter; and at March they will melte and breake and fal in manye small peces, the whiche is a newe dongynge and refreshynge of the corne.” This is agreeable to the present practice, founded on the very same reasons. “ In May, the shepe folde is to be set out;” but Fitzherbert does not much approve of folding, and points out its disadvantages in a very judicious manner. “ In thfe later end of May and the begynnynge of June, is tyme to wede the corne ;” and then we have an accurate description of the different weeds, and the instruments and mode of weeding. Next comes a second ploughing of the fallow ; and afterwards, in the latter end of June, the mowing of the meadows begins. Of this operation, and of the forks and rakes, and the haymaking, there is a very good account. The corn harvest naturally follows : rye and wheat were usu¬ ally shorn, and barley and oats cut with the scythe. This intelligent writer does not approve of the practice, which still prevails in some places, of cutting wheat high, and then mowing the stubbles. “ In Somersetshire,” he says, “ they do shere theyr wheat very lowe ; and the wheate strawe that they purpose to make thacke of, they do not threshe it, but cut off the ears, and bynd it in sheves, and call it rede, and therewith they thacke theyr houses.” He recommends the practice of setting up corn in shocks, with two sheaves to cover eight, instead of ten sheaves, as at present; probably owing to the straw being then shorter. The corn was commonly housed ; but if there be a want of room, he advises that the ricks be built on a scaffold, and not upon the ground. Corn-stacks are now beginning to be built on pillars and frames. The fallow received a third ploughing in September, and was sown about Michaelmas. “ Wheat is moost commonlye sowne under the forowe, that is to say, cast it uppon the falowe, and then plowe it under;” and this branch of his subject is concluded with directions about threshing, winnowing, and other kinds of barn-work. Fitzherbert next proceeds to live stock. “ An hous- bande, he says, “ can not well thryue by his corne with¬ out he have other cattell, nor by his cattell without corne. And bycause that shepe, in myne opynyon, is the mooste profytablest cattell that any man can haue, therefore I pourpose to speake fyrst of shepe.” His remarks on this subject are so accurate, that one might imagine they came hom a storemaster of the present day; and the minutiae w hich he details are exactly what the writer of this ar- , c e has seen practised in the hilly parts of this country, u some places, at present, “ they neuer seuer their ambes from their dammes ;” “ and the poore of the peeke ( ugh) countreye, and such other places, where, as they 'so to milke theyr ewes, they vse to wayne theyr lambes a. T've,, es olde, and to mylke their ewes fiue or syxe 'veekes; but that, he observes, “ is greate hurte to the 255 ewes, and wyll cause them that they wyll not take the A^ricul ramme a the tyme of the yere fo/ pouertye, but goo barreyne. “ In June is tyme to shere shepe ; and ere^v^ t1,ey muSt be verye well washen, the which shall be to the owner greate profyte in the sale of his wool, and also to the clothe-maker.” It appears that hand washing was then a common practice;’ and vet in the west and north of Scotland, at this day, sheep are never washed at all. His remarks on horses, cattle &c are not less interesting; and there is a very good account of the diseases of each species, and some just observations on the advantage of mixing different kinds on the same pasture. Swine and bees conclude this branch of the work. . I he author then points out the great advantages of inclosures ; recommends “ quycksettynge, dychynge, and hedgeyng;” and gives particular directions about the settes, and the method of training a hedge, as well as concerning the planting and management of trees. We have then a short information “ for a yonge gentylman that intendeth to thryue, and “ a prolouge for the wiues occupation,” in some instances rather too homely for the present time. Among other things, she is to “ make her husband and* herself somme clothes;” and “ she maye haue the lockes of the ^shepe eyther to make blankettes and courlettes, or bothe.” This is not so much amiss ; but what follows will bring our learned judge into disrepute even with our most industrious housewives. “ It is a wyues occupation,” he says, “ to wynowe all maner of cornes, to make malte, to washe and wrynge, to make heye, shere corne, and, in time of nede, to lielpe her husbande to fyll the mucke wayne or dounge carte, dryue the ploughe, to loode heye, corne, and suche other; and to go or ride to the market to sel butter, chese, mylke, egges, chekyns, capons, hennes, pygges, gese, and all maner of cornes.” The rest of the book contains some useful advices about diligence and economy; and concludes, after the manner of the age, with many pious exhortations. Such is Fitzherbert’s Book of Husbandry, and such was the state of agriculture in England in the early part of the sixteenth century, and probably for a long time be¬ fore; for he nowhere speaks of the practices which he describes or recommends as of recent introduction. The Book of Surveying adds considerably to our know¬ ledge of the rural economy of that age. “ Four maner of commens” are described; several kinds of mills for corn and other purposes, and also “ quernes that goo with hand;” different orders of tenants, down to the “ bound- men,” who “ in some places contynue as yet;” “ and many tymes, by colour thereof, there be many freemen taken as boundmen, and their lands and goods is taken from them.” Lime and marl are mentioned as common ma¬ nures ; and the former was sometimes spread on the sur¬ face to destroy heath. Both draining and irrigation are noticed, though the latter but slightly. And the work concludes with an inquiry “ how to make a township that is worth XX. marke a yere, worth XX. li. a year;” from which we shall give a specimen of the author’s manner, as well as of the economy of the age. “ It is undoubted, that to every townshyppe that stand- eth in tyllage in the playne countrey, there be errable landes to plowe and sowe, and leyse to tye or tedder theyr horses and mares upon, and common pasture to kepe and pasture their catell, beestes, and shepe upon; and also they have medowe grounde to get theyr hey upon. Than to let it be known how many acres of errable lande euery man hath in tyllage, and of the same acres in euery felde to chaunge with his neyghbours, and to leye them toguy- ther, and to make hym one seuerall close in euery felde for his errable lands ; and his leyse in euery felde to leye 256 A G R I C U Agricul- them togyther in one felde, and to make one seuerall close ture. for them all. And also another seuerall close for his por- tion of his common pasture, and also his porcion of his medowe in a seuerall close by itselfe, and al kept in seue- ral both in wynter and somer; and euery cottage shall haue his portion assigned hym accordynge to his rent, and than shall 'nat the ryche man ouerpresse the poore man with his cattell; and euery man may eate his oun close at his pleasure. And vndoubted, that hay and strawe that will find one beest in the house wyll finde two beestes in the close, and better they shall lyke. For those beestis in the house have short heare and thynne, and towards March they will pylle and be bare; and therefore they may nat abyde in the fylde before the heerdmen in winter tyme for colde. And those that lye in a close under a hedge haue longe heare and thyck, and they will neuer pylle nor be bare; and by this reason the husbande maye kepe twyse so many catell as he did before. “ This is the cause of this approwment. Nowe euery husbande hath sixe seuerall closes, whereof iii. be for corne, the fourthe for his leyse, the fyfte for his commen pastures, and the sixte for his haye; and in wynter time there is but one occupied with corne, and than hath the husbande other fyue to occupy tyll lente come, and that he hath his falowe felde, his ley felde, and his pasture felde al sommer. And when he hath mowen his medowe, than he hath his medowe grounde, soo that if he hath any weyke catell that wold be amended, or dyvers maner of catell, he may put them in any close he wyll, the which is a great advantage; and if all shulde lye commen, than wolde the edyche of the corne feldes and the aftermath of all the medowes be eaten in X. or XII. dayes. And the rych men that hath moche catell wold have the advantage,' and the poore man can have no helpe nor relefe in wynter when he hath moste nede; and if an acre of lande be worthe sixe pens, or it be enclosed, it will be worth VIII. pens whan it is enclosed, by reason of the compostying and dongyng of the catell that shall go and lye upon it both day and nighte ; and if any of his thre closes that he hath for his corne be worne or ware bare, than he may breke and plowe up his close that he hadde for his layse, or the close that he hadde for his commen pasture, or bothe, and sowe them with corne, and let the other lye for a time, and so shall he have aiway reist grounde, the which will bear moche corne with lytel donge; and also he shall have a great profyte of the wod in the hedges whan it is growen ; and not only these profytes and advantages beforesaid, but he shall save moche more than al these, for by reason of these closes he shall save meate, drinke, and wages of a shepeherde, the wages of the heerdman, and the wages of the swine herde, the which may fortune to be as charge¬ able as all his holle rent; and also his corne shall be bet¬ ter saved from eatinge or destroyeng with catel. For dout ye nat but heerdemen with their catell, shepeherdes with their shepe, and tieng of horses and mares, destroy- eth moch corne, the which the hedges wold save. Par- aduenture some men would say, that this shuld be against the common weale, bicause the shepeherdes, heerdmen, and swyneherdes, shuld than be put out of wages. To that it may be answered, though these occupations be not used, there be as many newe occupations that were not used before; as getting of quickesettes, diching, hedging, and plashing, the which the same men may use and oc- cupye.” Tusser. The next author who writes professedly on agriculture is Tusser, whose Five Hundred Points of Husbandry, L T U R E. published in 1562, was formerly in such high repute as to A be recommended by Lord Molesworth to be taught in schools.1 The edition of 1604 is the one we make use of^i here, in which the book of husbandry consists of 118 pages ; and then follows the Points of Housewifrie, occu¬ pying 42 pages more. It is written in verse. Amidst a vast heap of rubbish, there are some useful notices con¬ cerning the state of agriculture at the time in different parts of England. Hops, which had been introduced in the early part of the sixteenth century, and on the culture of which a treatise was published in 1574 by Reynolde Scott, are mentioned as a well-known crop. Buckwheat was sown after barley. It seems to have been the prac¬ tice then, in some places, to “ geld fillies’ as well as colts. Hemp and flax are mentioned as common crops. Inclo¬ sures must have been numerous in several counties; and there is a very good comparison between “ champion (open fields) country, and several,” which Blythe afterwards transcribed into his Improver Improved. Carrots, cab¬ bages, turnips, and rape, are mentioned among the herbs and roots for the kitchen. There is nothing to be found in Tusser about serfs or bondmen, as in Fitzherberfs works. This author’s division of the crop is rather curious, though probably quite inaccurate, if he means that the whole rent might be paid by a tenth of the corn. “ One part cast forth for rent due out of hand. “ One other part for seed to sow thy land. “ Another part leave parson for his tith. “ Another part for harvest, sickle and sith. “ One part for ploughwrite, cartwrite, knacker, and smith. “ One part to uphold thy teemes that draw therewith. “ Another part for servant and workman’s wages laie. “ One part likewise for filbellie daie by daie. “ One part thy wife for needful things doth crave. “ Thyself and thy child the last part would have.” The next writer is Barnaby Googe, whose Whole ArtGi of Husbandry was printed in 1578, and again by Markham in 1614. The first edition is merely a translation of a German work; and very little is said of English hus¬ bandry in the second, though Markham made some trifling interpolations, in order, as it is alleged, to adapt the Ger¬ man husbandry to the English climate. It is for the most part made up of gleanings from the ancient writers ot Greece and Rome, whose errors are faithfully retained, with here and there some description of the practices of the age, in which there is little of novelty or importance. Googe mentions a number of English writers who lived about the time of Fitzherbert, whose works have not been preserved. For more than fifty years after this, or till near the mid¬ dle of the seventeenth century, there are no systematic works on husbandry, though several treatises on particu¬ lar departments of it. From these it is evident, that all the different operations of the farmer were performed with more care and correctness than formerly; that the fal¬ lows were better worked, the fields kept freer of weeds, and much more attention paid to manures of every kind. A few of the writers of this period deserve to be shortly noticed. Sir Hugh Plat, in his Jewel House of Art and Nature, Y\ printed in 1594 (which Weston in his catalogue errone¬ ously gives to Gabriel Plattes), makes some useful obser¬ vations on manures, but chiefly collected from other wri¬ ters. His censure of the practice of leaving farm dung lying scattered about is among the most valuable. :ul. e. V 1 Some Considerations for the promoting of Agriculture and employing the Poor.

In Sir Richard Weston’s Discourse on the Husbandry of Brabant and Flan¬ ders, published by Hartlib in 1645, we may mark the dawn of the vast improvements which have since been effected in Britain. This gentleman was ambassador from England to the elector palatine and king of Bohemia in 1619, and Hartlib s Legacy is a very heterogeneous performance, Hartlib containing, among some very judicious directions, a great deal of rash speculation.

Laws against very useful person in editing tlie works of others, and as a collector of miscellaneous information on rural subjects. It is strange that neither Blythe nor Hartlib, nor any of Hartlib’s correspondents, seem ever to have heard of Fitzherbert’s works. _ Among the other writers previous to the Revolution, we shall only mention Ray the botanist and Evelyn, both men of great talents and research, whose works are still in high estimation. A new edition of Evelyn’s Silva and Terra was published in 1777 by Dr Hunter, with large notes and elegant engravings, and reprinted m 1812. The preceding review commences with a period ot feudal anarchy and despotism, and comes down to the time when the exertions of individual interest were pro¬ tected and encouraged by the firm administration of equal laws ; when the prosperity of Great Britain was no longer retarded by internal commotions, nor endangered by hos¬ tile invasion. The laws of this period, in so far as they relate to agri¬ culture and rural economy, display a similar progiess in improvement. t From the beginning of the reign of Henry VII. to the laying ara- en^ of Elizabeth’s, a number of statutes were made for hie land to the encouragement of tillage, though probably to little pasture, pUrp0se. The great grievance of those days was the practice of laying arable land to pasture, and suffering the farm-houses to fall to ruin. “ Where in some towns,” says the statute 4th Henry VII. (1488), “ two hundred persons were occupied and lived of their lawful labours, now there are occupied two or three herdsmen, and the residue fall into idleness therefore it is ordained, that houses which within three years have been let for farms, with twenty acres of land lying in tillage or husbandry, shall be upheld, under the penalty of half the profits, to be forfeited to the king or the lord of the fee. Almost half a centuiy afto¬ wards, the practice had become still more alarming; and in 1534 a new act was tried, apparently with as little suc¬ cess. “ Some have 24,000 sheep, some 20,000 sheep, some 10,000, some 6000, some 4000, and some more and some lessand yet it is alleged the price of wool had nearly doubled, “ sheep being come to a few persons’ hands.” A penalty was therefore imposed on all who kept above 2000 sheep; and no person was to take in farm more than two tenements of husbandry. By the 39th Elizabeth (1597), arable land made pasture since the 1st Elizabeth shall be again converted into tillage, and what is arable shall not be converted into pasture. ^ Many laws were enacted during this period against va¬ gabonds, as they were called ; and persons who could not find employment seem to have been sometimes confound¬ ed with those who really preferred idleness and plunder. The dissolution of the feudal system, and the suppression of the monasteries, deprived a great part of the rural po¬ pulation of the means of support. They could not be em¬ ployed in cultivating the soil, for there was no middle class of farmers possessed of capital to be vested in im¬ provements ; and what little disposable capital was in the hands of great proprietors could not, in those rude times, be so advantageously embarked in the expensive and pre¬ carious labours of growing corn, as in pasturage, which required much less skill and superintendence. Besides, there was a constant demand for wool on the Continent; while the corn-market was not only confined by laws against exportation, but fettered by restrictions on the in¬ ternal trade. The laws regarding the wages of labour and the price of provisions are a further proof of the ig¬ norance of the age in regard to the proper subject of le- A S1SBythe statute 1552 it is declared, that any person thatMxj shall buy merchandise, victual, &c. coming to market,^* or make any bargain for buying the same before they shall £ be in the market ready to be sold, or shall make any motion for enhancing the price, or dissuade any person from coming to market, or forbear to bring any of the things to market, &c. shall be deemed a forestaller. Any person who buys and sells again in the same market, or within four miles thereof, shall be reputed a regrater. Any person buying corn growing in the fields, or any other corn, with intent to sell again, shall be reputed an unlaw¬ ful ingrosser. It was also declared, that no person shall sell cattle within five weeks after he had bought them. Licences, indeed, were to be granted in certain cases, and particularly when the price of wheat was at or under 6s. 8d. a quarter, and other kinds of grain in that proportion. The laws regarding the exportation and importation ofamrte. corn during this period could have had little effect in en-guL couraging agriculture, though towards the latter part of™ it they gradually approached that system which was finally established at and soon after the Revolution. From the time of the above-mentioned statute against forestallers, which effectually prevented exportation, as well as the freedom of the home trade, when corn was above the price therein specified, down to 1688, there are at least twelve statutes on this subject; and some of them are so nearly the same, that it is probable they were not very carefully observed. The price at which wheat was allowed to be exported was raised from 6s. 8d. a quarter, the price fixed by the 1st and 2d of Philip and Mary (1553), to 10s. in 1562 ; to 20s. in 1593 ; to 26s. 8d. in 1604 ; to 32s. in 1623; to 40s. in 1660; to 48s. in 1663; and at last, in 1670, exportation was virtually permitted without limita¬ tion. Certain duties, however, were payable, which in some cases seem to have amounted to a prohibition; and until 1660 importation was not restrained even in years of plenty and cheapness. In permitting exportation, the object appears to have been revenue rather than the en¬ couragement of production. The first statute for levying tolls at turnpikes, to make or repair roads in England, passed in 1662. Of the state of agriculture in Scotland in the 16th andAi the greater part of the 17th century, very little is known ;^u no professed treatise on the subject appeared till after the^ Revolution. The south-eastern counties were the earliestaD improved, and yet in 1660 their condition seems to havece been very wretched. Ray, who made a tour along t ic eastern coast in that year, says, “ we observed little ox no fallow grounds in Scotland; some ley ground we saw, which they manured with sea wreck. The men seemed to be very lazy, and may be frequently observed to plough m their cloaks. It is the fashion of them to wear cloaks when they go abroad, but especially on Sundays, they have neither good bread, cheese, nor drink. They cannot make them, nor will they learn. Their butter is very in¬ different, and one would wonder how they could contrive to make it so bad. They use much pottage made of coal- wort, which they call kail, sometimes broth of decorticate barley. The ordinary country-houses are pitiful cots, bui of stone and covered with turfs, having in them but one room, many of them no chimneys, the windows very sma holes, and not glazed. The ground. in the valleys an plains bears very good corn, but especially bears bar ey bigge, and oats, but rarely wheat and rye.”1 > nil Select Remains of John Ray. Lond. 1760. AGRICULTURE. It‘s probable that no great change ban taken place in t e. Scotland from the end of the 15th century, except that tenants gradually became possessed of a little stock of their own, instead of having their farm stocked by the landlord. “ The minority of James V., the reign of Mary Stuart, the infancy of her son, and the civil wars of her grandson Charles L, were all periods of lasting waste. The very laws which were made during successive reigns, for protecting the tillers of the soil from spoil, are the best proofs of the deplorable state of (die husbandman.”1 Yet in the 17th century were those laws made which paved the way for the present improved system of agri¬ culture in Scotland; By statute 1633, landholders were en¬ abled to have their tithes valued, and to buy them either at nine or six years’ purchase, according to the nature of the property. The statute 1685j conferring on landlords a power to entail their estates, was indeed of a very dif¬ ferent tendency in regard to its effects on agriculture. But the two acts in 1695, for the division of commons, and separation of intermixed properties, have facilitated in an eminent degree the progress of improvement. j>:og 5s of From the Revolution to the accession of George III. the ipriqtureprogress of agriculture was by no means so considerable as fromj)88 we fog }ec[ t0 imagine from the great exportation of 101 f corn. It is the opinion of well-informed writers,2 that very little improvement had taken place, either in the cultivation of the soil or in the management of live stock, from the Restoration down to the middle of last century. Even clover and turnips, the great support of the present improved system of agriculture, were confined to a few districts, and at the latter period were scarcely cultivated at all by common farmers in the northern part of the island. Of the writers of this period, therefore, we shall notice only such as describe some improvement in the modes of culture, or some extension of the practices that were formerly little known. In Houghton’s Collections on Husbandry and Trade, a periodical work begun in 1681, we have the first notice of turnips being eaten by sheep. “ Some in Essex have their fallow after turnips, which feed their sheep in winter, by which means the turnips are scooped, and so made capable to hold dews and rain water, which, by corrupting, imbibes the nitre of the air, and when the shell breaks it runs about and fertilizes. By feeding the sheep, the land is dunged as if it had been folded; and those turnips, though few or none be carried off for human use, are a very excellent improvement, nay, some reckon it so though they only plough the turnips in without feeding.”3 This was written in February 1694; but ten years before, Wor- hdge, one of his correspondents, observes, “ sheep fatten very well on turnips, which prove an excellent nourish¬ ment for them in hard winters, when fodder is scarce ; for they will not only eat the greens, but feed on the roots in the ground, and scoop them hollow even to the very skin, len acres (he adds) sown with clover, turnips, &c. will eed as many sheep as one hundred acres thereof would before have done.”4 « Tk t^'S » Potatoes were beginning to attract notice. e potato, says Houghton, “ is a bacciferous herb, ww esculent roots, bearing winged leaves and a bell 259 “ This, I have been informed, was brought first out of irgima by Sir Walter Raleigh ; and he stopping at Ire¬ land, some was planted there, where it thrived very well A-ricul oIHIip g00d PurP°se ; for their succeeding warsfwhen ture. all the corn above the ground was destroyed, this supported them; for the soldiers, unless they had dug up all the ground where they grew, and almost sifted it, could not extn pate them ; from whence they were brought to Lan- cashire, where they are very numerous, and now they be" gm to spread all the kingdom over. They are a pleasant food boiled or roasted, and eaten with butter and sugar, ihere is a sort brought from Spain, that are of a longer xoi m? and are more luscious than ours ; they are much set by, and sold for sixpence or eightpence the pound.”5 The next writer is Mortimer, whose Whole Art of Mortimer Husbandry was published in 1706, and has since run through several editions. It is a regular, systematic work, of considerable merit; and it does not appear that much improvement has been made since in the practices he de¬ scribes, in many parts of Britain. From the third edition of Hartlib’s Legacy, we learn that clover was cut green, and given to cattle; and it appears that this practice of soiling, as it is now called, had become very common about the beginning of last century, wherever clover was cultivated. Ryegrass was now sown along with it. Tur¬ nips were hand-hoed, and extensively employed in feed¬ ing sheep and cattle, in the same manner as at present. The first considerable improvement in the practice ofTull. that period was introduced by Jethro Tull, a gentleman of Berkshire, who began to drill wheat and other crops about the year 1701, and whose Horse-hoeing Husbandry was published in 1731. In giving a short account of the innovations of this eccentric writer, it is not meant to en¬ ter into any discussion of their merits. It will not detract much from his reputation to admit that, like most other men who leave the beaten path, he was sometimes misled by inexperience, and sometimes deceived by a too san¬ guine imagination. Had Tull confined his recommenda¬ tion of the drill husbandry to leguminous and bulbous- rooted plants generally, and to the cereal gramina only in particular circumstances; and had he, without puzzling himself about the food of plants, been contented with pointing out the great advantage of pulverizing the soil in most cases, and extirpating weeds in every case, he would certainly have deserved a high rank among the benefactors of his country. A knowledge of his doctrines and practice, however, will serve as a necessary introduc¬ tion to the present approved modes of culture. Tull’s theory is promulgated with great confidence; and in the controversy which he thought proper to main¬ tain in support of it, he scrupled not to employ ridicule as well as reasoning. Besides the Roman writers De lie Bustica, Virgil in particular, whom he treats with high disdain, he is almost equally severe on Woodward, Brad¬ ley, and other writers of his own time. As the distance between his rows appeared much greater than was necessary for the range of the roots of the plants, Tull begins by showing that these roots ex¬ tend much farther than is commonly believed, and then proceeds to inquire into the nature of their food. After examining several hypotheses, he decides this to be fine particles of earth. The chief, and almost the only use of dung, he thinks, is to divide the earth, to dissolve “ this terrestrial matter, which affords nutriment to the mouths of vegetable rootsand this can be done more complete- 1 Chalmers’s Caledonia, vol. ii. p. 732. 1 Annals of Agriculture, No. 270.

Agricul- ly by tillage. It is therefore necessary not only to pul- ture. verize the soil by repeated ploughings before it be seed- but, as it becomes gradually more and more com¬ pressed afterwards, recourse must be had to tillage while the plants are growing, and this is hoeing, which also de¬ stroys the weeds that would deprive the plants of their nourishment. The leading features of Tull’s husbandry are his prac¬ tice of laying the land into narrow ridges of five or six feet, and upon the middle of these drilling one, two, or three rows, distant from one another about seven inches when there were three, and ten inches when only two. The distance of the plants on one ridge from those on the contiguous one he called an interval; the distance be¬ tween the rows on the same ridge, a space or partition: the former was stirred repeatedly by the horse-hoe, the latter by the hand-hoe. The extraordinary attention this ingenious person gave to his mode of culture is perhaps without a parallel:—“ I formerly was at much pains,” he says, “ and at some charge in improving my drills for planting the rows at very near distances, and had brought them to such per¬ fection, that one horse would draw a drill with eleven shares, making the rows at three inches and a half dis¬ tance from one another; and at the same time sow in them three very different sorts of seeds, which did not mix; and these, too, at different depths. As the barley- rows were seven inches asunder, the barley lay four inches deep. A little more than three inches above that, in the same channels, was clover; betwixt every two of these rows was a row of St Foin, covered half an inch deep. “ I had a good crop of barley the first year; the next year two crops of broad clover, where that was sown; and where hop-clover was sown, a mixed crop of that and St Foin ; but I am since, by experience, so fully convinced of the folly of these, or any other mixed crops, and more especially of narrow spaces, that I have demolished these instruments in their full perfection as a vain curiosity, the drift and use of them being contrary to the true prin¬ ciples and practice of horse-hoeing.1” In the culture of wheat, he began with ridges six feet broad, or eleven on a breadth of 66 feet; but on this he afterwards had fourteen ridges. After trying different numbers of rows on a ridge, he at last preferred two, with an intervening space of about ten inches. He allowed only three pecks of seed for an acre. The first hoeing was performed by turning a furrow from the row, as soon as the plant had put forth four or five leaves; so that it was done before or at the beginning of winter. The next hoeing was in spring, by which the earth was returned to the plants. The subsequent operations depended upon the circumstances and condition of the land and the state of the weather. The next year’s crop of wheat was sown upon the intervals which had been unoccupied the former year; but this he does not seem to think was a matter of much consequence. “ My field,” he observes, “ whereon is now the thirteenth crop of wheat, has shown that the rows may successfully stand upon any part of the ground. The ridges of this field were, for the twelfth crop, changed from six feet to four feet six inches. In order for this alteration the ridges were ploughed down, and then the next ridges were laid out the same way as the former, but one foot six inches narrower, and the double rows drilled on their tops; whereby, of consequence, there must be some rows standing on every part of the ground, both on the former partitions, and on every part of the intervals. Notwithstanding this, there was no Agi. manner of difference in the goodness of the rows; and ti the whole field was in every part of it equal, and the bcst^M I believe that ever grew on it. It is now the thirteenth crop, likely to be good, though the land was not ploughed crossways.”2 It follows from this singular management, that Tull thought a succession of crops of different species alto¬ gether unnecessary ; and he labours hard to prove against Ur Woodward, that the advantages of such a change un¬ der his plan of tillage were quite chimerical; though he seems to admit the benefit of a change of the seed itself. But the best method of determining the question would have been to have stated the amount of his crops per acre, and the quality of the grain, instead of resting the superiority of his management on the alleged saving of expense, when compared with the common broad-cast husbandry. On the culture of turnip, both his principles and his practice are much more correct. The ridges were of the same breadth as for wheat, but only one row was drilled on each. His management while the crop was growing differs very little from the present practice. When drilled on the level, it is impossible, he observes, to hoe-plough them so well as when they are planted upon ridges. But the seed was deposited at different depths, the half about four inches deep, and the other half exactly over that, at the depth of half an inch. “ Thus planted, let the weather be never so dry, the deepest seed will come up; but if it raineth immediately after planting, the shal¬ low will come up first. We also make it come up at four times, by mixing our seed half new and half old, the new coming up a day quicker than the old. These four comings up give it so many chances for escaping the fly; it being often seen that the seed sown over night will be destroyed by the fly, when that sown the next morning will escape, and vice versa : or you may hoe-plough them when the fly is like to devour them; this will bury the greatest part of these enemies: or else you may drill in another toav without new-ploughing the land.” Drilling and horse and hand-hoeing seem to have been in use before the publication of Tull’s book. “ Hoeing,” he says, “ may be divided into deep, which is our horse- hoeing; and shallow, which is the English hand-hoeing; and also the shallow horse-hoeing used in some places betwixt rows, where the intervals are very narrow, as 16 or 18 inches. This is but an imitation of the hand-hoe, or a succedaneum to it, and can neither supply the use of dung nor fallow, and may be properly called scratch- hoeing.” But in his mode of forming ridges his practice seems to have been original; his implements display much ingenuity; and his claim to the title of father of the pre¬ sent horse-hoeing husbandry'’ of Great Britain seems in¬ disputable. A translation of Tull’s book was undertaken at one and the same time in France, by three different persons of consideration, without the privity of each other. Two of them afterwards put their papers into the hands of the third, M. Du Hamel du Monceau of the Royal Academy of Sciences at Paris, who published a treatise on husbandry, on the principles of Mr Tull, a few years after. But Tull seems to have had very few followers in England for more than 30 years. The present method of drilling and horse-hoeing turnips was not introduced into Northumberland till about the year 1780 ;3 and it was then borrowed from Scotland, the farmers of which had the merit of first adopting Tull’s management in the cul- 1 Horse-hoeing Husbandry, p. 62.

It appears from this treatise, that the state of the art was not more advanced at that time in North Britain than it had been in Eng¬ land in the time of Fitzherbert. Farms were divided into infield and outfield; corn crops followed one another without the intervention of fallow, cultivated herbage, or turnips, though something is said about fallowing the outfield; inclosures were very rare; the tenantry had not begun to emerge from a state of great poverty and de¬ pression; and the wages of labour, compared with the price of corn, were much lower than at present; though that price, at least in ordinary years, must appear ex¬ tremely moderate in our times. Leases for a term of years, however, were not uncommon; but the want of capital rendered it impossible for the tenantry to attempt any spirited improvements. Donaldson first points out the common management of that period, which he shows to have been very unproduc¬ tive ; and afterwards recommends what he thinks would be a more profitable course. “ Of the dale ground,” he says, “ that is, such lands as are partly hills and partly valleys, of which sorts may be comprehended the greatest part of arable ground in this kingdom, I shall suppose a farmer to have a lease or tack of three score acres, at three hundred merks of rent per annum (L.16. 13s. 4d. sterling). Perhaps some who are not acquainted with rural affairs may think this cheap; but those who are the possessors thereof think otherwise, and find difficulty enough to get the same paid, according to their present way of manuring thereof. But that I may proceed to the comparison, I shall show how commonly this farm-room is managed. It is commonly divided into two parts, viz. one-third croft, and two-thirds outfield, as it is termed. The croft is usually divided into three parts; to wit, one- tliird barley, which is always dunged that year barley is sown thereon ; another third oats ; and the last third peas. The outside field is divided into two parts, to wit, the one half oats, and the other half grass, two years successively. Hie product which may be supposed to be on each acre of croft, four bolls (three Winchester quarters), and that of the outfield, three (2^- quarters) ; the quota is seven score bolls, which we shall also reckon at five pounds (8s. 4d.) per boll, cheap year and dear year one with another. This, in all, is worth L.700 (L.58. 6s. 8d. sterling). “ Then let us see what profit he can make of his cattle. According to the division of his lands, there is 20 acres of grass, which cannot be expected to be very good, be¬ cause it gets not leave to lie above two years, and there¬ fore cannot be well swarded. However, usually, besides tour horses, which are kept for ploughing the said land, ten or twelve nolt are also kept upon a farm-room of the above-mentioned bounds; but, in respect of the badness of the grass, as said is, little profit is had of them. Per¬ haps two or three stone of butter is the most that can be made of the milk of his kine the whole summer, and not 261 above two heffers brought up each year. As to what Agricul- profit may be made by bringing up young horses, I shall ture. say nothing, supposing he keeps his stock good by those of his own upbringing. The whole product, then, of his cattle cannot be reykoned above fifty merks (L.2. 15s. 6d ) For, in respect his beasts are in a manner half-starved they are generally small; so that scarce may a heffer be sold at above twelve pounds (L.l sterling). The whole product of this farm-room, therefore, exceeds not the value of L.733 (L.61. Is. 8d. sterling), or thereabout.” The la¬ bourers employed on this farm were two men and one woman, besides a herd in summer, and other servants in harvest.’ Donaldson then proceeds to point out a different mode of management, which he calculates to be more profit¬ able ; but no notice is taken of either clover or turnips as crops to be raised in his new course, though they are incidentally noticed in other parts of the work. “ I also recommend potatoes as a very profitable root for husbandmen and others that have numerous families. And because there is a peculiar way of planting this root, not commonly known in this country, I shall here show what way it is ordinarily planted or set. The ground must be dry; and so much the better it is if it have a good soard of grass. The beds or riggs are made about eight foot broad, good store of dung being laid upon your ground; horse or sheep dung is the proper manure for them. Throw each potatoe or sett (for they were some¬ times cut into setts) into a knot of dung, and afterwards dig earth out of the furrows, and cover them all over, about some three or four inches deep; the furrows left between your riggs must be about two foot broad, and little less will they be in depth before your potatoes be covered. You need not plant this root in your garden; they are commonly set in the fields, and wildest of ground, for enriching of it.” As to their consumption, they were sometimes “ boiled and broken, and stirred with butter and new milk; also roasted, and eaten with butter; yea, some make bread of them, by mixing them with oat or barley meal; others parboil them, and bake them with apples, after the manner of tarts.” There is a good deal in this little treatise about sheep, and other branches of husbandry; and, if the writer was well informed, as in most instances he appears to have been, his account of prices, of wages, and generally of the practices of that period, is very interesting. The next work on the husbandry of Scotland is, ThejMX& Bei. Countrymans Rudiments, or an advice to the Farmers haven. in East Lothian, how to labour and improve their grounds ; said to have been written by Lord Belhaven about the time of the Union, and reprinted in 1723. In this we have a deplorable picture of the state of agriculture in what is now the most highly improved county in Scot¬ land. His lordship begins with a very high encomium on his own performance. “ I dare be bold to say, there was never such a good easy method of husbandry as this, so succinct, extensive, and methodical in all its parts, published before.” And he bespeaks the fa¬ vour of those to whom he addresses himself, by adding, “ neither shall I affright you with hedging, ditch¬ ing, marling, chalking, paring and burning, draining, watering, and Such like, which are all very good improve¬ ments indeed, and very agreeable with the soil and situ¬ ation of East Lothian ; but I know ye cannot bear as yet a crowd of improvements, this being only intended to ini¬ tiate you in the true method and principles of husbandry.” The farm-rooms in East Lothian, as in other districts, were divided into infield and outfield. “ The infield (where wheat is sown) is generally divided by the tenant into four divisions, or breaks, as they call them, viz. one 262 AGRICULTURE. Agricul- of wheat, one of barley, one of pease, and one of oats; so ture. that the wheat is sowed after the pease, the barley after ',-0!^v>,^/the wheat, and the oats after the barley. The outfield land is ordinarily made use of promiscuously for feeding of their cows, horse, sheep, and oxen; ’tis also dunged by their sheep, who lay in earthen folds ; and sometimes, when they have much of it, they fauch or fallow a part of it yearly.” Under this management the produce seems to have been three times the seed; and yet, says his lordship, “ if in East Lothian they did not leave a higher stubble than in other places of the kingdom, their grounds would be in a much worse condition than at present they are, though bad enough.”—“ A good crop of corn makes a good stubble, and a good stubble is the equalest mucking that is.” Among the advantages of inclosures, he observes, “ you will gain much more labour from your servants, a great part of whose time was taken up in ga¬ thering thistles and other garbage for their horses to feed upon in their stables; and thereby the great trampling and pulling up, and other destruction of the corns, while they are yet tender, will be prevented.” Potatoes and turnips are recommended to be sown in the yard (kitchen- garden). Clover does not seem to have been in use. Rents were paid in corn ; and, for the largest farm, which he thinks should employ no more than two ploughs, the rent wns about six chalders of victual “ when the ground is very good, and four in that which is not so good. But I am most fully convinced they should take long leases or tacks, that they may not be straitened with time in the improvement of their rooms; and this is profitable both for master and tenant.” Society of Such was the state of the husbandry of Scotland in the Improvers, early part of last century. The first attempts at improve¬ ment cannot be traced farther back than 1723, when a number of landholders formed themselves into a society, under the title of the Society of Improvers in the Know¬ ledge of Agriculture in Scotland. The earl of Stair, one of their most active members, is said to have been the first who cultivated turnips in that country. The Select Transactions of this society were collected and published Maxwell, in 1743 by Mr Maxwnll, who took a large part in its proceedings. It is evident from this book that the society had exerted itself in a very laudable manner, and appa¬ rently with considerable success, in introducing culti¬ vated herbage and turnips, as well as in improving the former methods of culture. But there is reason to believe that the influence of the example of its numerous mem¬ bers did not extend to the common tenantry, who are al¬ ways unwilling to adopt the practices of those who are placed in a higher rank, and supposed to cultivate land for pleasure rather than profit. Though this society, the earliest probably in the United Kingdom, soon counted upwards of 300 members, it existed little more than 20 years. Maxwell delivered lectures on agriculture for one or two sessions at Edinburgh, which, from the specimen he has left, ought to have been encouraged. In the introductory paper in Maxwell’s collection, we are told, that “ the practice of draining, inclosing, summer fallowing, sowing flax, hemp, rape, turnip and grass seeds, planting cabbages after, and potatoes with, the plough, in fields of great extent, is introduced ; and that, according to the general opinion, more corn grows now yearly where it was never known to grow before, these twenty years last past, than perhaps a sixth of all that the kingdom was in use to produce at any time before.” Invention In this work we find the first notice of a threshing-ma- of a _ chine ; it was invented by Mr Michael Menzies, advocate, threshing- w]10 obtained a patent for it. Upon a representation made mac me. t0 society that it was to be seen working in several places, they appointed two of their number to inspect it; a and in their report they say, that one man would be sufficient to manage a machine which would do the work^ of six. One of the machines was “ moved by a great water¬ wheel and triddles,” and another “ by a little wheel of three feet diameter, moved by a small quantity of water.” This machine the society recommended to all gentlemen and farmers. The next work is by the same Mr Maxwell, printed in 1757, and entitled the Practical Husbandman; being a collection of miscellaneous papers on Husbandry, &c. In this book the greater part of the Select Transactions is re¬ published, with a number of new papers, among which, an Essay on the Husbandry of Scotland, with a proposal for the improvement of it, is the most valuable. In this he lays it down as a rule, that it is bad husbandry to take two crops of grain successively, which marks a consider¬ able progress in the knowledge of modern husbandry; though he adds, that in Scotland the best husbandmeti after a fallow take a crop of wheat; after the wheat, peas; then barley, and then oats; and after that they fallow again. The want of inclosures was still a matter of com¬ plaint. The ground continued to be cropped so long as it produced twm seeds; the best farmers were contented with four seeds, which was more than the general produce. The first act of parliament for collecting tolls on the highway in Scotland was passed in ITbO, for repairing the road from Dunglass bridge to Haddington. In ten years after, several acts followed for the counties of Edin¬ burgh and Lanark, and for making the roads between Edinburgh and Glasgow. The benefit which agriculture has derived from good roads, it would not be easy to esti¬ mate. The want of them was one great cause of the slow progress of the art in former times. The Revolution in 1688 was the epoch of that system of corn laws to which very great influence has been ascribed, both on the practice of agriculture and the general pro¬ sperity of the country. But for an account of these and later statutes on the subject, we must refer to the article Cohn Laws. The exportation of wTool was prohibited in 1647, in 1660, and in 1688 ; and the prohibition strictly enforced by subsequent statutes. The effect of this on its price, and the state of the wool trade,’ from the earliest period to the middle of last century, are distinctly exhibited by the learned and laborious author of Memoirs on Wool, printed in 1747. The gradual advance in the price of land produce Prog soon after the year 1760, occasioned by the increase ofdncc population, and of wealth derived from manufactures and commerce, has given a more powerful stimulus to rural industry, augmented agricultural capital in a greater de¬ gree, and called forth a more skilful and enterprising race of cultivators, than all the laws for regulating the corn trade could ever have effected. Most of the inven¬ tions for increasing produce and economizing labour have either been introduced, or improved and greatly extended, since that time ; and by means of both, the free surplus has been vastly increased for the supply of the general consumption. The passing of more than 3000 bills of inclosure, in the late reign, before which the whole num¬ ber was only 244, is a proof how much more rapidly the cultivation of new land has proceeded than formerly; and the garden-like appearance of the country, as well as the striking improvement in the condition of all classes of the rural population, display, in the most decided manner, the skill and the success with which this great branch of national industry is now followed throughout the greater part of Britain. 'Ul. !. \ a AGRICULTURE. 263 In a view of the progress of husbandry, any consider- U" able improvements in the species of crops cultivated, and s^^the order in which they succeed one another, in agricul¬ tural machinery, and in the kinds and varieties of live stock, are entitled to hold a very prominent place. Our limits do not permit us to do more than just to notice a few of the most important here; but we shall have occasion to describe them more fully in the second part of this ar¬ ticle, when treating on the practice and present state of our agriculture. . jUte ite The great line of distinction between the present and huskdry. former courses of cropping, consists in the alternation of what are called exhausting and ameliorating crops. The best cultivators rarely take two corn crops in suc- •cession; but corn is almost universally succeeded by a leguminous crop, or one of herbage, cut or pastured, or turnips, cabbages, rape, &c.; or, when the soil is not suited to turnips, by a summer fallow, recurring at as distant an interval as its condition will permit. In common lan¬ guage, a green or a pulse crop, or a plain fallow, is interposed between every two white corn crops. These green crops not only preserve the fertility of the soil, but when sown in rows, as most of them usually are, they afford an opportunity of extirpating weeds, by the use of the horse and hand hoe ; and even when sown broad-cast, by their taking complete possession of the ground, if it is properly prepared, the growth of weeds is effectually checked. In other respects, these interme¬ diate crops are of the utmost importance in every good course of management. Whether they be eaten on the ground or carried to the farm houses and straw yards, much valuable manure is obtained from their consump¬ tion ; and on sandy or gravelly soils, when only a part of a turnip crop is eaten by sheep on the ground, the greatest defect of such land is removed by their treading, and in many cases it is rendered capable of producing as valuable a crop of wheat as soils of a closer texture. It is for these reasons that, by the cultivation of clover, and turnips in particular, in regular alternation with corn, the soil is so much enriched as to yield as much corn on the half of any given extent of land as the whole did under the old course of successive crops of corn; and, unless upon strong clays, an unproductive fallow is wholly dis¬ pensed with. But these crops are not less valuable in another point of view. Before the introduction of clover and turnips, there was nothing for the maintenance of live stock but natural herbage in summer, with the addition of hay and straw in winter; and in the northern parts of the island in particular, where the winters are long and severe, it was seldom possible to do more, for about half the year, than preserve cattle and sheep from starving. Even in the most favourable situations, very little butcher-meat could be brought to market from December to June, un¬ less at an expense wdiich the great body of consumers were quite unable to reimburse. The more early matu¬ rity of cattle and sheep, and the regular supply of the market throughout the year, are therefore chiefly owing to turnips and clover, as well as the vast increase in the number of the live stock kept on arable land, and the great degree of perfection to which some breeds have been brought by the skilful experiments of several eminent agriculturists. Among these, the first place is unquestionably due to e'" Ilobert Bakewell of Dishley, in Leicestershire. By his skilful selection at first, and constant care afterwards, to breed from the best animals, he at last obtained a va¬ riety of sheep, which, for early maturity, and the property of returning a great produce of mutton for the food they consume, as well as for the small proportion which the Agricul- weight of the offal bears to that of the four quarters, are ture. altogether unequalled either in this or any other country, The Dishley or new Leicester sheep, and their crosses, are now spread oyer the principal corn districts of Britain; and, from their quiet domesticated habits, are probably still the most profitable of all the varieties of sheep, on farms where the rearing and fattening of live stock are combined with the best courses of tillage crops. < The practice of Mr Bakewell and his followers fur¬ nishes an instance of the benefits of the division of labour, in a department of business where it was little to be ex¬ pected. Their males were let out every year to breeders from all parts of England; and thus, by judiciously cross¬ ing the old races, all the valuable properties of the Dish¬ ley variety descended, after three or four generations, to their posterity. By no other means could this new breed have spread so rapidly, or been made to accommodate it¬ self so easily to a change of climate and pasture. Another recommendation of this plan was, that the ram-hirer had a choice among a number of males of somewhat different properties, and in a more or less advanced stage of im¬ provement, from which it was his business to select such as suited his particular object. These were reared by ex¬ perienced men, who gave their principal attention to this branch alone; and having the best females as well as males, they were able to furnish the necessary supply of young males in the greatest variety, to those farmers whose time was occupied with other pursuits. The prices at which Mr Bakewell’s rams were hired appear enor¬ mous. In 1789 he received twelve hundred guineas for the hire of three brought at one birth; two thousand for seven; and for his whole letting, at least three thousand guineas. Merino sheep were first brought into England in 1788, Merinos, when his late Majesty procured a small flock by way of Portugal. In 1791 another flock was imported from Spain. In 1804, when the annual sales commenced, this race began to attract much notice. Dr Parry of Bath crossed the Ryeland or Herefordshire sheep with the Merinos, and brought the wool of the fourth generation to a degree of fineness not excelled, it is said, by that of the pure Merino itself; while the carcass, in which the great defect of the Merinos consists, has been much im¬ proved. Lord Somerville and many other gentlemen have bestowed much attention on this valuable race, which, however, has not spread itself over the country; and the wool is understood to have deteriorated. One of the most valuable plants introduced into culti-Swedish vation since 1760 is the ruta baga or Swedish turnip, turnip, which in a great degree supplies the great desideratum of late spring food for live stock, after the common turnip is generally much damaged, and sometimes almost wholly destroyed, by the severity and changes of the weather. The Scotish yellow turnip is for the same reason a most useful variety, coming in between the white turnips and the Swedish, in some situations supplying the place of the latter, and yielding generally a larger produce. A new variety of oats, called the potato oat, was accidentally discovered in 1788. It comes early, and gives, a large pro¬ duce both in grain and in meal, on good soils; and was soon cultivated over all the north of England and south of Scotland. But it has already begun to degenerate. A good many varieties of summer wheat have been intro¬ duced of late, but they are only partially cultivated. Under the head of agricultural machinery, we need only Threshing notice the improvement of the swing-plough by Small, machine, and of the threshing-machine by Meikle ; though the lat¬ ter may rather claim the entire merit of the invention. 264 AGRICULTURE. Agricul¬ ture. We shall have Occasion to notice in its proper place the progress that has been made towards perfecting a ma¬ chine for reaping corn, still an important desideratum. The agriculture of Scotland has been benefited by an act in 1770, which relaxed the rigour of strict entails, and extended the powers of proprietors, in so far as re¬ gards the improvement of their estates and the granting of leases; but there is still much room for improvement in this branch of our legal polity. Agricultu- There is nothing that shows more clearly the rapid pro- ral Socle- gress of agriculture in Britain, than the great number of societies that have been lately formed, one or more in al¬ most every county, for the diffusion of knowledge, and the encouragement of correct operations and beneficial discoveries. We have already noticed the Society of Improvers established in Scodand in 1723. Besides those respectable associations which have for their object the encouragement of arts, manufactures, and commerce generally, several large institutions have been formed, whose chief purpose is the improvement of agriculture. Among these the Bath and West of England Society, es¬ tablished in 1777, and the Highland Society of Scotland, in 1784, hold a conspicuous rank; nor ought we to pass over in silence the labours of the National Board of Agri¬ culture, formed in 1793, but since abolished, which by means of the county-surveys has made us acquainted with the rural affairs of every part of the kingdom. A great many excellent works on agriculture, and rela¬ tive subjects, have been published since 1760; and among these several periodical miscellanies have been favourably received and widely circulated. But as they are com¬ paratively recent, and the best of them well known, it is unnecessary to give any particular account either of their merits or defects. Sj Soils. Part II. The Practice of British Agriculture. We come now to our leading object, the present state of British agriculture, especially as it is found in our best cultivated counties. It is not our purpose to exhibit general views of a statistical nature,—such as the extent and produce of our territory, considered under the seve¬ ral divisions of corn-land, pastures, and wastes or tracts still in a state of nature. The proportion which each of these bears to the whole cannot perhaps be fixed with tolerable accuracy at any time, and is continually varying; and with regard to the aggregate produce, we have seen nothing but conjectural estimates, which, as might be ex¬ pected, differ greatly from one another. . The first thing which naturally calls for our attention in a treatise on the practice of agriculture is the Soil, which may be termed the raw material on which the cul¬ tivator has to operate, and according to the nature of which his general management as well as his labour in detail must in a great measure be regulated. In penetrating the superficial stratum, the first circum¬ stance which presents itself is the different degree of re¬ sistance required to be overcome in different situations. Its component parts are found to be more or less cohesive ; in some places nearly all of the same consistency, and in others mixed with decayed roots and small stones. The colour is also different, without any perceptible difference in other respects. These are the obvious varieties which occur immediately beneath the surface, or in what is pro¬ perly called the soilj but upon going a little deeper, the texture and. colour undergo further changes, even in the same situation. A compact, impervious mass, often im¬ bedded with stones, sometimes succeeds to a superficial stratum of the most incohesive materials: elsewhere th solid and dense surface soil passes, though commonly h* ' slower gradations, into a substratum of an opposite de^ scription; and in many parts the rock itself, from which the soil is supposed to have been formed, rises so near the surface as to stop all further progress. In addition to these obvious distinctions, it is soon ob¬ served that some soils are slow to admit moisture, and do not speedily part with it, but when dried become so in- durated as to be reduced to a pulverulent state with great difficulty; while others are so porous as to allow water to pass through them freely, and so open to the influence of the atmosphere, that if it meets with any obstruction from the subsoil, it is very soon carried off by evaporation. In the classification of soils with a view to practical uti¬ lity, therefore, they may be all reduced under two general divisions, according to their texture. The terms stiff heavy, strong, cohesive, and others of the same import, all denote soils of which the basis or principal ingredient is clay ; as, on the other hand, those in which sand predo¬ minates are called loose, light, porous, friable. Under each of these divisions, however, there are several varie¬ ties, such as gravel, loam, chalk, calcareous, alluvial, peaty, &c.; to which are added the common epithets of rich and poor, cold and hot, thin or shallow, and deep, and various others. Of the crops best suited to these several kinds of soil, Crop it is only necessary to observe here, that wheat, beans,diffa clovers, and fibrous-rooted plants generally, are most pro-soils. ductive on clays; while barley, turnips, and all bulbous and deep-rooted plants, thrive best in sandy soils. Loam, which may partake of either character, is an artificial soil, produced by cultivation and manure, and, when sufficient¬ ly deep, adapted to crops of every kind. Gravelly soils, which are usually considered as forming a distinct class, take their character from that of the rocky materials in which they abound. When very loose and porous, they are sometimes called hungry, the manure applied to them being as it were devoured and lost, from the want of mate¬ rials in a state to be acted upon; but those of a better quality are not only productive both in corn and pasture, but their crops ripen very early. Calcareous matter, such as lime, chalk, and marl, is a necessary ingredient in all fertile soils, without which, indeed, it has been found im¬ practicable to bring most crops to perfection. The soils formed by matters deposited by the tides and by rivers, called alluvial, usually consist of a variety of ingredients, and are for the most part very fertile. What is called a mossy or peaty soil is distinguished by its dark colour and spongy texture, and abounds in the roots of plants in a state of decay, from which, indeed, it seems to have been wholly formed. It is found in a great variety of situations, on the summits of mountains as well as in plains and hollows ; in some cases so saturated with water as not to bear the weight of cattle, in others in so solid a form as to be cut for fuel; sometimes of the depth of many feet, and elsewhere of only a few inches; but in all situations its produce of stunted heath, occasionally intermixed with coarse herbage, is of little or no value. This description of soil, if it deserves the name, is of comparatively recent formation, having been found in several instances super¬ incumbent upon cultivated soils which themselves appear to be alluvial, and consequently not of the earliest class. The terms moor and moorish are applied generally to in¬ ferior soils in a state of nature, whatever may be their distinctive character in other respects. The quality of soils may sometimes be judged of with tolerable accuracy, by attending to the species of plants which they naturally produce, and observing whether they AGRICULTURE. . ui. grow close and vigorous, so as to cover the soil complete- t > fy, or rise feeble and scattered, with unoccupied spaces ^ ^between. The clovers, for instance, grow freely on calca¬ reous soils, and the common ragwort (senecio Jacobcea) and the corn-thistle (serratula Arvensis) usually indicate a fertile soil, whatever be its texture. Science has sup¬ plied other tests, for which we may refer to Sir Humphry Davy’s Agricultural Chemistry. One of the simplest methods of ascertaining the presence of calcareous matter in the soli, is to pour upon it any strong acid, with which, if this ingredient abounds, it will effervesce freely. The power of retaining moisture, and, when dry, of absorbing it from the atmosphere, as well as the greater increase of temperature, which under the same circumstances takes place in some soils,—these and various other criteria may be employed to determine their comparative fertility. And, what is not unworthy of remark, it is known from experience that the productiveness of the soil, under similar circumstances in other respects, depends in some measure on the dryness or humidity of the climate. In the west of Scotland, for instance, where much more rain falls than in the east, light sandy soils do not suffer so much under a severe course of cropping as they are found to do in the latter situation. Lat,;. In describing the practice of agriculture, it may be nent thought that the process by which lands in a state of nature are first brought into cultivation would be entitled to our earliest consideration, and that we should then pro¬ ceed to describe the successive operations by which our fields have arrived at their present condition. But a moment's reflection may convince us that such an arrange¬ ment would be inexpedient, if not impracticable, on the present occasion. The original state of much of our cul¬ tivated land, which has long since passed away, must have been very different in different situations, and would re¬ quire a corresponding variety of operations to prepare it for growing corn ; and a number of implements, however rude, must have been constructed, even before these operations could be commenced. It is only in an ad¬ vanced stage of the art, and as a branch of general ma¬ nagement, that the culture of wastes can demand our at¬ tention; for it is then only that capital and science may en¬ able us to cultivate them with advantage. But without pretending to scientific arrangement, we shall content ourselves with bringing together those parts of our subject that have a mutual relation and dependence on one another in practice, and endeavour to present its more important details under the four following chapters. In first, we shall treat of what regards the cultiva¬ tion and products of arable land ; in the second, of the management of grass lands, and the improvement of wastes ; in the third, of agricultural live stock ; and in fourth, which will be of a more general kind, we shall endeavour to point out those circumstances which have more particularly contributed to the improvement of agri¬ culture in this country, and those also which seem still to obstruct its further advancement. ihere are, besides the subjects which fall to be treated under these divisions, some others, which certainly form component parts of agricultural science, and to which it will be necessary to advert in this work; but as these sub¬ jects are not of equal interest to husbandmen generally, and as they are capable of being treated with advantage m a separate form, we shall reserve them for distinct 265 articles, to be afterwards introduced under their respec- A~ri™l ftve heads. Such are the subjects of the Da.kv? of tar™ Drainage, of Embankment, of Irrigation, and ofv Woods and Plantations. CHAP. I. ARABLE LAND. We shall endeavour to arrange all the most important detads connected with this division of our subject un¬ der the following sections1. Of implements and ma¬ chinery : 2. Of farm-buildings; 3. Of fences: 4. Of tillage : 5. Of fallowing: 6. Of the cultivation of the dif¬ ferent crops: 7. Of the order of their succession: 8. Of the various substances used as manure, and the modes of apply¬ ing them. 1 J Sect. I. Implements and Machinery. The numerous implements of tillage husbandry may be arranged under these six heads;—such as are employed, 1. in preparing land for semination; 2. in depositing the seed; 3. during the growth of the plants ; 4. in reaping and securing the crop ; 5. in preparing it for market; and, 6. in the general purposes of a farm. But as the same implement is sometimes used for more than one purpose, it would be of little consequence to adhere strictly to this or any other arrangement. The implements required for rendering land fit for tillage do not belong to this part of the article, and several others that have not yet been brought into general use, or are employed only for parti¬ cular purposes, shall be noticed under the sections to which they respectively belong. 1. Ploughs. Of ploughs there are a great many different sorts; and, Ploughs, besides the variety of construction occasioned by the dif¬ ference of soils, and the different purposes for which they are employed even on the same soil, there is a considerable diversity in the form, in districts where both the soil and the mode of culture are nearly alike. The most obvious general distinction among ploughs is, their being con¬ structed with or without wheels : and each of these kinds may be again distinguished by other circumstances ;—such as the form of the mould-board and share; their operation in making one or more furrows at a time; their size; and the depth at which they are calculated to work, as in trench-ploughing. It would neither be of much utility, nor at all consistent with our limits, to describe all the numerous varieties of form. The nature of the operation to be performed, and the rules for constructing ploughs that shall be adapted to the different purposes of the cul¬ tivator, have been fully described in a variety of works, particularly in those noted below and all that is neces¬ sary here is to mention those ploughs that are in most ge¬ neral use in the best cultivated districts. The Swing-plough, with a feathered sock or share, and Swing, a curved mould-board, is almost the only one used in Scot-plough, land, and throughout a considerable part of England. The old Scotish plough with a spear sock has been laid aside, except in a few of the least improved counties, where it is still found useful when the soil is encumbered by roots or stones. The swing-plough is drawn with less power than wheel-ploughs, the friction not being so great; and it pro- Small s Treatise on Ploughs and Wheel-Carriages, 178-1: Lord Karnes’s Gentleman Farmer; and Bailey on the Construction of the Plough on Mathematical Principles. yOL.

It is usually drawn by two 'horses abreast in common tillage; but for ploughing be¬ tween the rows of the drill culture, a smaller one, drawn by one horse, is commonly employed. A plough of this kind, having a mould-board on each side, is also used, both in forming narrow ridges for turnips and potatoes, and in laying up the earth to the roots of the plants, after the intervals have been cleaned and pulverized by the hoise and hand hoe. This plough is sometimes made in such a manner that the mould-board may be shifted from one side to the other when working on hilly grounds; by which means the furrows are all laid in the same direction ; a mode of construction as old as the days of Fitzherbert, who wrote before the middle of the sixteenth century. This is called a turn-wrest plough. Swing-ploughs, similar to the present, have been long known in England. In Blythe’s Improver Improved (edit. 1652), we have engravings of several ploughs; and what he calls the “ plain plough” does not seem to differ much in its principal parts from the one now in use. Amos, in an Essay on Agricultural Machines, says that a person named Lummis (whom he is mistaken in calling a Scotch¬ man, see Maxwell’s Practical Husbandman, y. 191.) “first attempted its construction upon mathematical principles, which he learned in Holland; but having obtained a patent for the making and vending of this plough, he withheld the knowledge of these principles from the public. How¬ ever, one Pashley, plough-wright to Sir Charles Turner of Kirkleatham, having a knowledge of those principles, con¬ structed upon them a vast number of ploughs. After¬ wards his son established a manufactory for the making of them at Rotherham. Hence they obtained the name of the Rotherham plough ; but in Scotland they were called the Dutch or patent plough.”—“ At length the Americans, having obtained a knowledge of those prin¬ ciples, either from Britain or Holland, claimed the priority of the invention; in consequence of which, Mr Jefferson, president of the United States, presented the principles for the construction of a mould-board, first to the Institute of France, and next to the Board of Agriculture in Eng¬ land, as a wonderful discovery in mathematics.” (CW- munications to the Board of Agriculture, vol. vi. p. 437.) According to another writer, the Rotherham plough was first constructed in Yorkshire in 1720, about ten years before Lummis’s improvements. (Survey of the West Rid¬ ing of Yorkshire.') But the present improved swing-plough was little known in Scotland till about the year 1764, when Small’s method of constructing it began to excite attention. This ingeni¬ ous mechanic formed the mould-board upon distinct and intelligible principles, and afterwards made it of cast-iron. Flis appendage of a chain has been since laid aside. It has been disputed whether he took the Rotherham or the old Scotish plough for the basis of his improvements. The swing-plough has been since varied a little from Small’s form, for the purpose of adapting it more completely to particular situations and circumstances. Of late it has been made entirely of iron. See Plate V. Wheel-ploughs, used in many parts of England, are also constructed in a great variety of forms. Their chief recommendation is, that they require less skill in the ploughman; but it is admitted, that the friction caused by the wheels adds to the resistance, and that they are more expensive, and more liable to be put out of order, as well as to be disturbed in their progress by clods, stones, and other inequalities, than those of the swing kind. Wheel-ploughs, says Dr Dickson (Practical Agri¬ culture, vol. i. p. 7.), should be seldom had recourse to by the experienced ploughman, though they may be more ^ convenient and more manageable for those who are not ti' perfectly informed in that important and useful art. ^ The Plertfordshire and Kentish turn-wrest wheel-plough, as well as the swing-plough, are described by Blythe; and they do not seem to have received much improvement since his time. The former is thought most suitable for general purposes on stiff tenacious soils, and the latter where very deep ploughing is required. On light, loamy, and friable soils, where deep ploughing is not necessary, the Norfolk wheel-plough will be found convenient and useful: it is compact and light in its form, doing its work with neatness, and requiring only a small power of draught. To the improved common wheel-plough an iron earth-Skink board, firmly screwed to the coulter, has been lately added, ter. It is made use of when ploughing turf, which it takes off by itself, and turns into the furrow, immediately covering it with earth. It is observed that, by this management, turf at one ploughing has the appearance of a fallow, and harrows nearly as well; but more strength is required in the team. A similar sort of skim coulter may be added to any other plough, and may be useful in turning down green crops and long dung, as well as in trench-plough¬ ing. But in most instances it is thought a preferable plan, where the soil has to be stirred to an unusual depth, to make two common swing-ploughs follow each other in the same track ; the one before taking a shallow furrow, and the other going deeper, and throwing up a new furrow upon the former. Two-furrow ploughs are used in a few places, but are Tm not likely ever to become general. They are constructed row either with or without wheels. A plough of this kind wasPlou strongly recommended by Lord Somerville, and used by his lordship and others, apparently with some advantages. In Blythe’s Improver Improved, there is an engraving of this plough also. But with all the improvements made by Lord Somerville, it can never come into competition for general purposeswith the present single furrow ploughs; and he admits that it would be no object to invade the system already established in well-cultivated counties; though, where large teams are employed, with a driver besides the ploughman, it would certainly be a matter of importance to use this plough, at least on light friable soils. “ Their horses,” he says, “ will not feel the difference between their own single furrow working one acre, or the well-constructed two-furrow plough with two acres per day; here is no system deranged, and double work done.’ (Communications to the Board of Agriculture, vol. ii. p* 4J8.) Amos, already mentioned, has gone much beyond this. Tw In his Essay in the Board’s Communications formerly re-^ ferred to, he gives a description, with an engraving, of machine which combines “ two, three, or four ploughs^, together, for ploughing furrows nine by five inches square. On soils of a tenacity next to clay, “ six horses will draw four ploughs, four horses three ploughs, and three horses two ploughs, and every plough to plough an acre a day. It is scarcely necessary to add, that such machines are altogether unfit for agricultural operations; the nature and condition of the soil and surface, varied in ways innu¬ merable, will never permit the general use of them; and even in the few situations where they may be employed, there is reason to believe that ploughing cannot be done cheaper, and certainly not so well as by the two-horse single furrow plough. Various other implements under the name of ploughs ^ have been constructed for stirring the soil;—such as the Miner, for following in the furrow of a common plough, Mil AGRICULTURE. 267 W- and loosening the ground to a greater depth, without shape, each containing twenty tines, five or six inches Aericul u bringing up the subsoil; the Paring Plough, and the long beneath the hulls or bars in which they are inserted tore ^'^Mole and other sorts of ploughs for draining, some of It is still common for every harrow to work senaratelv- which shall be afterwards noticed under their proper heads, and though always two, and sometimes three harrows are Self -an- A plough has been recently constructed by Mr John placed together, each of them is drawn by its own horee fog? igh.

The plough, as is well known, covers the old and exposes lighter harrows are used, which are so constructed, that all the ruts are equidistant. See Plate V. The brake, as commonly constructed, is nothing more Brake, than a heavier harrow, sometimes in one, and sometimes in two pieces joined together; the tines being in number and length, and in the distance from one another at which they are placed, suited to the nature of the soil on which it is employed.

Some of them are used in pre¬ paring it for the seed, and others, as horse-hoes, between drilled crops. It were to no purpose to enumerate and describe all these ; we shall here notice only such as we know to be of practical utility. One of them, called a grubber, from its efficiency in bringing weed-roots to the surface, consists of two strong rectangular frames, the one including the other, and nine bars mortised into the inner one, with eleven qpulters or tines with triangular sharp- edged dipping feet, four cast-iron wheels, two handles, &c. See Plate V. All the coulters are fixed in these bars except two, which are placed in the side beams of cultural implement maker, Edinburgh, and is called the Revolving Brake Harrow. When the soil has been suffi¬ ciently reduced, this is perhaps the best implement of any for bringing the roots to the surface; and to a certain ex¬ tent it also acts in pulverizing the land when under fal¬ low, so as to save one or two ploughings. See Plate VI. (Farmer s Magazine, vol. xviii. &c.)

Agricul¬ ture. In Scotland, turnips are universally sown with a drill- machine, on ridges 27 or 30 inches broad, usually formed ' by one bout of a common plough. When turnips are ex¬ tensively grown, the machine is made to sow two of these ridges at once, and two rollers are attached to it, one for smoothing the tops of the ridges before the seed is depo¬ sited, and the other for compressing the soil and covering the seed. The front roller is now made concave, which leaves the ridges in a better form for the seed. It is drawn by one horse walking between the ridges, and re- ouiring no other driver than the person who guides the machine, which is simple in its construction, and most expeditious in its operation. See Plate VII. Beans and peas, when sown in rows, are either depo¬ sited in the space between two ridgelets, which are after¬ wards reversed to cover them, or in the bottom of a fur¬ row made by a common plough,—in Scotland, usually in that of every third furrow. The implement in most com¬ mon use for this purpose is extremely simple, and is either wheeled forward by a man, or attached to the common plough itself. the seed falls, with small ridges between, the seed is bet- Api ter covered than by harrowing alone. But rollers are tu chiefly used for the purpose of smoothing and compressing the soil and breaking down clods; and their weight is va¬ ried accordingly. See Plate VII. 7. Horse-Rakes. In those districts where corn is cut with the scythe,Hors the horse-rake is found to be a useful implement forrakea saving manual labour; it is also used for hay. The teeth are of iron, 14 or 15 inches in length, and set five or six inches distant. Its construction is very simple. A man and horse are said to be capable of clearing from 20 to 30 acres in a moderate day’s work, disposing the grain in lines across the field, by lifting up the rake and dropping it from the teeth, without stopping the horse. One of these has been lately used in the neighbourhood of Edin¬ burgh for raking hay, and has given much satisfaction. See Plate VI. 8. Threshing-Machines. 5. Horse-Hoes. Horse- The interval between the rows of drilled turnips, pota- hoes. toes, and beans and peas, being commonly from 2 to 2^ feet, admits the employment of a horse-hoe or hoeing- plough. Of this kind of machine there are a great many varieties. A very good one is described in the Isorthum- berland Report, p. 43; the body is of a triangular form, and contains three coulters and three hoes, or six hoes, according to the state of the soil. A hoe of the same kind is sometimes attached to a small roller, and employed between rows of wheat and barley, from 9 to 12 inches distant; it is also used in place of a cultivator, in pre¬ paring bean stubbles for wheat in autumn, and in pulve¬ rizing lands for barley in spring. Small Another implement, which serves both as a double plough and mould-board plough and a horse-hoe, is much approved horse-hoe of in the culture of drilled crops; and with some slight in one. alterations it may be also employed as a small plough for taking the earth from the sides of the ridgelets. When it is used as a horse-hoe, the mould-hoards are taken off, and two curved cutters or coulters expand from the beam on each side, to a less or greater distance, according to the width of the interval between the plants, and approach each other in the bottom of the furrow, where the share supplies their place. This machine is well adapted for light soils, and can be set to work very near the rows of plants; it is particularly useful in cutting up annual weeds preparatory to hand-hoeing, which it greatly faci¬ litates. When it is to be employed as a single or double Universal mould-board plough, the cutters are withdrawn. A very complete implement, answering these different purposes, drill- plough and is known under the name of Morton’s Universal Drill harrow. Plough and Harrow, which is found very convenient in the hands of skilful ploughmen, and seems well suited for the use of small farms, or situations where a variety of implements is not often required; so many of these being combined in one, and admitting of being easily separated and used each by itself. See Plate VII. G. Rollers. Rollers. These are constructed of wood, stone, or cast-iron, and of different dimensions, according to the purposes for which they are used. The spike-roller is employed in some places when the soil rises in large masses, difficult to be reduced. The Norfolk drill-roller, on which rings of iron are fixed at small distances, is considered a useful implement, as, by forming parallel ruts into which Threshing-machines are now common in every part ofThre Scotland, on farms where the extent of tillage land re-math quires two or more ploughs; and they are every year spreading more and more in England and Ireland. They are worked by horses, water, wind, and of late by steam; and their powers and dimensions are adapted to the vari¬ ous sizes of farms. Water is by far the best power; but as a supply cannot be obtained in many situations, and as wind and steam require too much expense for most farms, horses are still employed more generally than any other power. Where wind-mills are erected, it is found necessary to add such machinery as may allow them to be worked by horses occasionally, in very calm weather; and the use of steam must be confined • for the most part to the coal districts. All the essential parts of this machine will be noticed in describing the engraving (Plate IX.), though several slight alterations are occasionally introduced. One of the most useful of these, perhaps, is the method of deli¬ vering the straw, after it has been separated from the corn by the circular rake, to wdiat is called a travelling-ln shaker, which carries it to the straw-barn. This shaker, which revolves like the endless web formerly used fors!ia‘ conveying the corn to the beaters, is composed of small rods, placed so near as to prevent the straw from falling through, while any threshed corn that may not have been formerly separated drops from it in its progress, instead of falling along with it, where it would be trodden down and lost. It is well known that the work of horses at threshing- mills is unusually severe, if continued for any length ot time; that they sometimes draw unequally; that they, as well as the machine itself, are much injured by sudden jerks and strains, which are almost unavoidable ; and that, from this irregularity in the impelling power, it requires much care in the man who presents the corn to the rol¬ lers, to prevent bad threshing. It is therefore highly de¬ sirable that the labour should be equalized among the horses, and the movements of the machine rendered as steady as possible. A method of yoking the horses in such a manner as compels each of them to take his proper share of the labour has accordingly been lately introduced, and the necessary apparatus, which is neither complicated nor expensive, can be added to any machine worked by animal power. {Farmer s Magazine, vol. xiii. p. 279.) See Plate IX. All well-constructed threshing-mills have one winnow¬ ing-machine, which separates the chaff1 from the corn be- AGRICULTURE. 269 fore it reaches the ground; and a second sometimes re- ‘ cejves it from the first, and gives it out ready for market, ✓Wor nearly so; the work done varying with the power and the kind of grain from three to six or eight quarters in the hour. If the height of the building does not admit of this last addition, a separate winnowing-machine, when the mill is of great power, is driven by a belt from it. In either of these ways there is a considerable saving of manual labour. And with a powerful water-mill, it can¬ not be doubted that corn is threshed and dressed at no more expense than must be incurred for dressing alone when threshed with the flail. Besides, the corn is more completely detached from the straw; and, by being threshed expeditiously, a good deal of it may be preserved in a bad season which would have spoiled in a stack. The great advantage of transferring forty or fifty quarters of grain in a few hours, and under the eye of the owner, from the yard to the granary or market, is of itself suf¬ ficient to recommend this invaluable machine, even though there were no saving of expense. I A machine of this kind, which is worked by one or two hrcs! g- men, may probably be found useful on small farms. It nill. is made for L.8 or L.10, and is said to thresh ten or twelve bushels in an hour. (Id. p. 409.) In some parts of England portable machines are in use, and carried from one farm to another, like any common implement. 9. Winnowing-Machine. rt"nr>. This is said to be of Chinese invention, and to have np-m; been brought to Europe by the Dutch, from whom it bine, reached Scotland in the early part of the last century. They were first made by a person of the name of Rodgers, near Hawick, in Roxburghshire, who happened to see one in a granary at Leith in the year 1733, though it would appear that one had been brought from Holland to East Lothian, along with a barley-mill, twenty-two years be¬ fore. Yet it does not seem to have been then known to farmers, nor did it come into general use till long after 1733; and in some parts of England and of the north of Scotland it is not employed even at this day. Two men and three women will dress and measure up into sacks, in about ten hours, from twenty to twenty-five quarters of corn, by means of this machine. 10. Chaff-Cutter, and similar Implements. Chaffj ,t. Chaff-cutters may be either wrought separately by ma- :er. nual labour, or by being attached to some other machine. This implement, like the operation it performs, is sufficient¬ ly simple, though its construction is various. MacdougaTs patent chaff-cutter is understood to be one of the most useful of the kind, and may be easily repaired, when ne- Fiim cessary, by any common mechanic. Another tool of a ‘her similar description is partially used for cutting turnips, which is often an advantageous practice, especially in feeding sheep of a year old in spring, after they have cast Mitclifcs their first teeth. Various contrivances are also adopted for ci ingby some farmers for cutting or bruising corn for horses, ^r1’l l!1f’which ought to become a more general practice, particu¬ larly for old horses, and such as swallow their coni with- Stean) g out mastication. Akin to these inventions is the steaming '1'iwr is. apparatus, which should be considered a necessary ap¬ pendage to every arable and dairy farm of a moderate size. The advantages of preparing food for live stock by means of steam begin now to be generally and justly ap¬ preciated. 11. Wheel- Carriages. Waggons, though they may possess some advantages over carts in long journeys, and when fully loaded, are now admitted to be much less convenient for the general Agricul- purposes of a farm, and particularly on occasions which ture. require great dispatch, as in harvesting the crop. Ac-'^~v'“x“y cording to Marshall, the waggons used in Gloucestershire are the best in England. (Rural Economy of Gloucester¬ shire.') In some places the improved Irish car is employ¬ ed for light loads, while the waggon continues to be used for other purposes. Carts, drawn by one or two horses, are, however, the Carts, only farm-carriages of some of the best cultivated coun¬ ties, and no other are ever used in Scotland. Their load depends upon the strength of the horses and nature of the roads; but in every case, it is asserted that a given number of horses will draw a great deal more, according to some one-third more, in single-horse carts than in wag¬ gons. Two-horse carts are still the most common among farmers in Scotland; but those drawn by one horse, two of which are always driven by one man, are unquestionably preferable for most purposes. The carriers of the west of Scotland usually load from a ton to a ton and a half on a single-horse cart, and nowhere does it carry less than 12 cwts. if the roads are tolerable. For corn in the straw, and hay, the farmers of the south Corn and of Scotland and north of England use a sparred frame, hay cart, which is made to fit the same wheels from which the close body of the cart is removed. In other places the close body is retained, and movable rails attached to it for these loads. See Plate VI. Carts are varied in their construction to suit different Coup-cart, purposes. A very convenient carriage for home work, called a coup-cart, discharges its load with great ease and expedition ; the fore part of the close body being made to rise up from the shafts on drawing out an iron pin, while the other end sinks, and allows the load to fall to the ground. Broad wheels, with conical or convex rims, are common Broad in England ; in Scotland the wheels are generally narrow, wheels, though broader ones are beginning to be introduced. Those used for the common or two-horse carts are usu¬ ally about 41 feet high, and mounted on iron axles. The advantages of broad cylindrical wheels have been illus¬ trated with much force and ingenuity in several late pub¬ lications. ( Communications to the Board of Agriculture, vol. ii. and vol. vii. Part i.) 12. Reaping-Machines. An implement capable of performing the process ofReaping- reaping corn is yet a desideratum in agricultural machi-machines, nery, but which will probably be supplied, at least for fa¬ vourable situations, at no distant period. In all field ope¬ rations, dispatch, in such a climate as this, is a matter of great importance; but in reaping corn at the precise pe¬ riod of its maturity, the advantages of dispatch are incab culable, especially in those districts where the difficulty of procuring hands, even at enormous wages, aggravates the danger from the instability of the season. It cannot, therefore, fail to be interesting, and we hope it may be also useful, to record some of the more remarkable at¬ tempts that have been made towards an invention so emi¬ nently calculated to forward this most important operation. The first attempt of this kind, so far as we have learn-Mr Boyce’s, ed, was made by a Mr Boyce, who obtained a patent for a reaping-machine about 30 years ago. This ma¬ chine was placed in a two-wheeled carriage, somewhat resembling a common cart, but the wheels were fixed upon the axle, so that it revolved along with them. A co<>’-wheel within the carriage turned a smaller one at the upper end of an inclined axis, and at the lower end of this was a larger wheel, which gave a rapid motion to a 270 AGRICULTURE. Agricul- pinion fixed upon a vertical axis in the fore part of the ture. carriage, and rather on one side, so that it went before one of the wheels of the carriage. The vertical spindle descended to within a few inches of the surface of the ground, and had there a number of scythes fixed upon it horizontally. This machine, when wheeled along, would, by the rapid revolution of its scythes, cut down a portion of the corn growing upon the grdund over which it passed; but hav¬ ing no provision for gathering up the corn in parcels and laying it in proper heaps, it was wholly unfit for the pur¬ pose. Mr Pluck- An agr icultural implement maker of London, Mr Pluck- net’s. Mr Glad, stones’s. Mr Sal¬ mon’s. Mr Smith's, net, attempted some years afterwards to improve this ma¬ chine. The principal alteration he made was in substitut¬ ing for the scythes a circular steel plate, made very sharp at the edge, and notched on the upper side like a sickle. This plate acted in the same manner as a very fine-toothed saw, and was found to cut the corn much better than the scythes of the original machine. A description and drawing of a machine, invented by Mr Gladstones of Castle Douglas, in the stewartry of Kirk¬ cudbright, are given in the Farmer s Magazine, vol. vii. p. 273. It operated upon nearly the same principles with Mr Plucknet’s; but Mr Gladstones made it work much better by introducing a circular table, with strong wooden teeth notched below all around, which was fixed imme¬ diately over the cutter, and parallel to it. The use of these teeth was to collect the corn and retain it till it was operated on by the circular cutter. The corn when cut was received upon this table, and, when a sufficient quan¬ tity was collected, taken away by a rake or sweeper, and laid upon the ground beneath the machine, in separate parcels. To this machine was added a small circular wheel of wood covered with emery, which, being always in contact with the great cutter at the back part, or op¬ posite side to that where the cutting was performed, kept it constantly ground to a sharp edge. The next attempt was made by Mr Robert Salmon of Woburn, Bedfordshire, whose invention, it is said, pro¬ mised better than those we have mentioned. It was con¬ structed upon a totally different principle, as it cut the corn by means of shears ; and it was provided with a very complete apparatus for laying it down in parcels as it was cut. One of the most promising machines of this kind of which we have received any account, was constructed by Mr Smith, of the Deanston Cotton Works, Perthshire. He made the first trial of it upon a small scale, during the har¬ vest of 1811. It was then wrought by two men. In 1812 he constructed one upon a larger scale, to be wrought by a horse; but though he cut down several acres of oats and barley with considerable ease, it was found that, when met by an acclivity, the horse could not move the machine with proper effect. In 1813 he made a more successful attempt with an improved machine, worked by one man and two horses; and in 1814) it was still further improved by an additional apparatus, tending to regulate the appli¬ cation of the cutter when working on an uneven surface. The cutter of this machine is circular, and operates ho¬ rizontally ; it is appended to a drum connected with the fore part of the machine, its blade projecting some inches beyond the periphery of the lower end of the drum (See Plate VIII.); and the machine is so constructed as to com¬ municate, in moving forward, a rapid rotatory motion to this drum and cutter, by which the stalks are cut, and, falling upon the drum, are carried round and thrown off in regular rows. This ingenious piece of machinery will cut about an English acre per hour, during which time eaP the cutter requires to be four times sharpened with a com- A* mon scythe-stone. The expense is estimated at from t L.30 to L.35. If properly managed, it may last for many^ sj years, only requiring a new cutter every two or three years; a repair which cannot cost much. But we are sorry to learn that, after some not unsatisfactory trials, Mr Smith has not found it convenient to prosecute his invention. A more recent attempt has been lately made by Bel Mr Patrick Bell, A. M. His machine was tried at^ Gowrie, in the county of Forfar, in the month of Sep-cllil tember 1829, in cutting down oats, barley, and wheat, on ground of uneven surface and considerable declivity. It is about five feet broad, and consequently cuts down this breadth of corn as it moves onward. The stubble left was from three to four inches high ; and the cut corn was deposited as the machine advanced, in a very regular manner. It was worked by one horse, and may cost about L.30, the work done being at about the rate of an imperial acre in the hour. In the opinion of the farmers and others present at this trial, this machine will come immediately into general use, and confer a signal benefit on agriculture. {Quarterly Journal of Agriculture, &c. No. III. p. 331.) The Flemish or Hainault scythe has been tried at dif-Ha ft ferent times, and recommended as a better implement forscj reaping corn than the sickle or scythe in common use; and it was lately brought fully before the public, under the patronage of the Highland Society of Scotland. At the request of this society, M. Masclet, late French con¬ sul at Edinburgh, brought over two young men from Flan¬ ders to show the use of this implement, and to instruct our own labourers. The trials were made, after public notice, in several parts of Scotland, with the different va¬ rieties of grain, and under different circumstances as to the state of the crop at the time ; and the results seem to be very much in its favour. The straw was cut nearly as close as with the common scythe, taken up clean except where the crop was very thin, and laid down regularly in a proper state for binding and threshing. A man will cut with this implement two roods or half an acre a day; and the saving has been calculated as equal to about one-third of what would be required to cut the same crop by the sickle now in use. See Plate VI. Still, however, the most common implement for reapingSic is either the teethed hook or the smooth sickle, sometimesha called the scythe-hook. It has been disputed which of these is preferable. The sickle cuts the straw like a scythe, and where the crops are strong, there can be no doubt that the work is performed with much less labour, and the crop taken up equally clean as by the teethed hook. But where the crop is thin and straggling, some of the stalks drop to the ground as they are cut, instead of being gathered and taken up, as they would have been by the teethed hook. We have thus noticed all the most important imple¬ ments in general use, and shall have occasion, under the proper heads, to advert to some others that are only em¬ ployed occasionally. Our limits require us to pass over those of a more simple kind, which are well known, and may be found fully described in a variety of publications. (See Communications to the Board of Agriculture, the County Reports, and the General Report of Scotland.) Sect. II. Farm-Houses. Suitable farm-buildings are scarcely less necessary toft the husbandman than implements and machinery, and ho might, without much impropriety, be classed along with AGRICULTURE. • . them, and considered as one great stationary machine, ftur'" operating more or less on every branch of labour and pro- tVyduce. There is nothing which marks more decidedly the state of agriculture in any district than the plan and exe¬ cution of these buildings. In erecting farm-houses, the first thing that deserves notice is their situation, both in regard to the other parts of the farm, and the convenience which they ought them¬ selves to possess. In general, it must be of importance on arable farms, that the buildings should be set down at nearly an equal distance from the extremities; or so si¬ tuate that the access from all the different fields should be easy, and the distance from those most remote no greater than the size of the farm renders unavoidable. The advantages of such a position in saving labour are too obvious to require illustration ; and yet this matter is not nearly so much attended to as its importance deserves. In some cases, however, it is advisable to depart from this general rule, of which one of the most obvious is, when a command of water for a threshing-mill and other pur¬ poses can be better secured in another quarter of the farm. The form most generally approved for a set of offices is that of a square, or rather a rectangular parallelogram, the houses being arranged on the north, east, and west sides, and the south side fenced by a stone wall, to which low buildings for calves, pigs, &c. are sometimes attached. The space thus inclosed is usually allotted to young cattle : these have access to the sheds on one or two sides, and are kept separate, according to their size or age, by one or more partition-wqlls. The farmer’s dwelling-house stands at a short distance from the offices, and frequently com¬ mands a view of the inside of the square ; and cottages for servants and labourers are placed on some convenient spot, not far from the other buildings. The number and arrangement, as well as the size of the different houses, must depend in some degree on the extent of the farm and the general management. It is therefore only necessary to notice particularly those which are indispensable in every case on an arable farm, and the degree of accommodation they should afford, m. The barn is always set down so as to be as convenient as possible for the stack-yard, wherever corn is put up in stacks instead of being immediately carried from the field to the barn itself. Relatively to the other buildings, its situation may be varied according to circumstances ; but two things should be-attended to ; first, its contiguity to the granary ; and, second, its facility of access for furnish¬ ing straw to the cattle-houses. In the plan delineated in Plate VL, it is placed in the middle of the north range, with one end projecting into the stack-yard, and the other, where the straw is lodged, on a line with stables on one side, and cattle-houses on the other, and having a door opening towards the straw-yards. As it is to be un¬ derstood throughout this description that a threshing-mill is employed, a width of from 20 to 30 feet within walls, on die length of this side of the square, will generally be suffi¬ cient for the straw-house. The height of the barn must be such as to allow at least one winnowing-machine to be attached to the mill, and its length is determined by the size of the farm. renat A granary is an indispensable accommodation on all to¬ lerably large farms, and is commonly, though in many cases improperly, placed above the cart-sheds, to be after¬ wards noticed. From experience and observation, we would recommend that the granary should be under the roof of the barn, immediately above the floor on which the 271 machine works ; and that the com should be raised to it Agricul- from the ground-floor either by the threshing-mill itself, tore, or a common windlass, easily worked by one man. When'^'v^>f it is to be taken out and carried to market, it may be lowered down upon carts, v/ith the utmost facility and dispatch. There is evidently no greater expense incur¬ red by this arrangement, for the same floor and height of side-walls that must be added to the barn are required in whatever situation the granary may be, and it possesses several advantages. Owing to its being higher than the adjacent buildings, there is a freer circulation of air, and less danger of pilfering, or of destruction by vermin ; the corn can be deposited in it as it is dressed, without being exposed to the weather; while the saving of labour is in most cases considerable. This plan has been lately re¬ commended by several agricultural writers,1 and has been found exceedingly convenient in practice. Stables are now constructed in such a manner that all Stables, the horses stand in a line with their heads towards the same side-wall, instead of standing in two lines, fronting opposite walls, as formerly. Those lately erected are at least sixteen feet wide within walls, and sometimes eighteen, and the width of each stall upon the length of the stable is commonly five feet. To save a little room, stalls of nine feet are sometimes made to hold two horses ; and in that case the manger and the width of the stall are divided into equal parts by what is called a half-tre- vice, or a partition about half the depth of that which se¬ parates one stall from another. By this contrivance, each horse indeed eats his food by himself; but the expense of single stalls is more than compensated by the greater ease, security, and comfort of the horses. The trevices, or partitions which divide the stalls, are of deals two inches thick, and about five feet high; but at the heads of the horses the partition rises to the height of seven feet, and the length of the stall is usually from seven to eight feet. The manger is generally continued the whole length of the stable. It is about nine inches deep, twelve inches wide at the top, and nine at the bottom, all inside mea¬ sure, and is placed about two feet four inches from the ground. Staples or rings are fixed in the breast of the manger, to which the horses are tied. The rack for holding their hay or straw is also com¬ monly continued the whole length of the stable. It is formed of upright spars, connected by cross rails at each end, and from two to two and a half feet in height. The rack is placed on the wall, about one foot and a half above the manger, the bottom almost close to the wall, and the top projecting outwards so as to form an angle with it of twenty or twenty-five degrees. The spars are sometimes made round, and sunk into the cross rails, and sometimes square. In a few stables lately built, the round spars turn on a pivot, which facilitates the horse’s access to the hay* without requiring the interstices to be so wide as to per¬ mit him to draw it out in too large quantities. Immediately above the racks is an opening in the hay¬ loft, through which the racks are filled. When it is thought necessary, this may be closed by boards moving on hinges. Behind the horses, and about nine feet from the front wall, is a gutter, having a gentle declivity to the straw- yard or urine-pit. Allowing about a foot for this, there will remain a width of eight feet to the back wall, if the stable be eighteen feet wide; a part of which, close to the wall, may be occupied with corn-chests and places for harness. 1 Dickson’s Practical Agriculture, voL i. p. 43 ; and General Report of the Agricultural State of Scotland, vol. i. p. 141. 272 AGRICULTURE. Agricul¬ ture. Cattle- houses. Root- house. Cattle and cart- sheds. In some of the best stables the racks occupy one of the angles between the wall and trevices, and form the qua¬ drant of a circle. The spars are perpendicular, and wider placed than in the hanging racks. The ha}r-seed falls into a box below, instead of being dropped on the ground, or incommoding the eyes and ears of the horses. With a view to save both the hay and the seed, it is an advantage to have the hay-stack so near the stable as to admit of the hay being thrown at once upon the loft. In some stables there is no loft, and the hay is stored in a separate apartment. The floor is, for the most part, paved with undressed stones ; but, in some instances, the space from the gutter to the back wall is laid with flags of freestone. According to the plan we are describing, cattle-houses are placed on the other side of the straw-house, and, with a root-house, complete the north side of the square. The extent of these, it is evident, depends not only on the size of the farm, but on the general management, and must vary according as rearing, fattening, or daily cattle, form the principal object. To avoid prolixity, let it be understood that this part of the range is allotted to fattening cattle. There are three ways in which the cattle are placed ; first, in a row towards one of the side walls; second, in two rows, either fronting each other, with a passage between, or with their heads towards both side walls; and, third, across, or upon the width of the house, in successive rows, with intervening passages for feeding and removing the dung. In the first plan it is usual to have openings in the walls, through which they are supplied with turnips, otherwise they must necessarily be served from behind, with much inconvenience both to the cattle-feeder and the cattle themselves. The plan that is most approved of, and which is now becoming general when new buildings are erected, is to fix the stakes to which the cattle are tied about two and a half or three feet from the wall; which allows the cattleman, without going among them, to fill their troughs successively from his wheelbarrow or basket with much ease and expedition. It is also a considerable improve¬ ment to keep the cattle separate by partitions between every two. This will in a great measure prevent acci¬ dents, and secure the quiet animals from being injured by the vicious ; for, in these double stalls, each may be tied up to a stake placed near the partition, so as to be at some distance from his neighbour; and it is easy to lodge together such as are alike in size and in temper. The width of such stalls should not be less than 71 feet, and the depth must be regulated by the size of the cattle. Wherever a number of cattle are fed, an apartment is required for containing turnips, potatoes, Arc. when brought from the field, until they are dealt out into the troughs. This apartment is placed either on the line of the cattle- houses, or begins another side of the square, at the angle of the junction of the two sides. The outer door ought to be so large as to admit a loaded cart; and there is an inner door that opens into the feeder’s walk along the heads of the cattle. At the other end of this, a door opens into the straw-house; so that their food and litter are not exposed to the weather, and the labour of the feeder is greatly diminished. The east and west sides of the square consist chiefly of sheds for the strawr-yard cattle, and cart-sheds. But stables for young horses, riding-horses, and for separating the sick from the others, may be placed upon that side which connects with the common stable already described; and, in like manner, a part of the opposite side, connect¬ ing with the cattle-houses, may be allotted to cows ; or, ifi necessary, the feeding-houses may be continued. The cattle-sheds are open towards the straw-yards, and the cart-sheds outwards to the road. On one of these sides there should be a close apartment for small tools, and an- ^ other for preparing corn and roots by steam, which maySA also serve for other purposes. In some convenient place * near the stables and cattle-houses, or immediately over them, there should be sleeping-rooms for the servants who have the charge of them, that they may be at hand in case of accidents during the night. Along the wall which completes the inclosure, such low j buildings may be set down, particularly hog-styes andai % poultry-houses, as may be thought desirable. These styes should open behind into the straw-yards, to which thel! ^ hogs should have access for picking up corn left on the straw, and such turnips, clover, &c. as are refused by the cattle. When they are kept in great numbers, it may be necessary to allot them a range of styes, with yards in front, in another place, as is commonly done by gentle¬ men farmers; but it is absurd fastidiousness in a rent¬ paying farmer to exclude these profitable animals from a place where a few of them will make themselves fat without a shilling of expense, and without any real in¬ jury to the cattle among which they feed. It will be seen from the engraving (Plate XL), that a road, which should be always kept in good order, goes along three sides of this square, from which there is access to the houses, instead of entering through the^traw-yards from the inclosed area. All the houses in which live stock are kept have an opening behind towards the straw- yards, for carrying out their dung. This plan, which, with slight variations, required by circumstances, is common in the north of England and south of Scotland, is meant to combine convenience with economy, and is well adapted to most arable farms in the occupancy of tenants. Proprietors who farm, sometimes choose to add several other buildings, and at the same time to vary a little their distribution. Thus, it is com¬ mon to separate the straw-yards from the sides of the square by a cart-way, towards which all the doors open, and the hog-styes with yards are usually placed behind one of the sides where they are least exposed to obser¬ vation. In every case, it is absolutely necessary that there should be water in or near the area. In the plan deline-tr ated in Plate XI. a pump is placed at the end of the wall which divides the area, and along this wall are fixed troughs, to which the cattle on each side have access at all times. When a great number of cattle are fed at the stake, itU is necessary to have a reservoir near the square to receive their urine. The urine is either applied to the land in its liquid state, or earth, peat-moss, &c. is thrown into the pit in such quantities as may be necessary to absorb it. Sometimes the reservoir is sunk below the area, and the urine raised by a pump, and spread over the straw- yard. But on those arable farms where no more cattle are reared or fattened, and no more turnips consumed at the homestead, than what are needed for converting the straw into manure, a reservoir for urine is not required, the whole of it being absorbed by the straw as it is dropped. The practice of feeding cattle in small sheds and straw-fi yards, or what are called hammels in Berwickshire, de¬ serves to be noticed with approbation, when saving of ex¬ pense is not a paramount object. Two cattle are usually kept together, and go loose, in which way they are thought by some to thrive better than when tied to a stake, and, at the same time, feed more at their ease than when a number are kept together, as in the common straw-yards. All that is necessary is, to run partition-walls across the sheds and yards already described; or if these are allotted ■pit iwl: .

Agrieul- the course of crops which the quality of the soil points ture. out as the most advantageous; and that, upon all farms ‘ not below a medium size, there should be twice the num¬ ber of inclosures that there are divisions or breaks in the course. Thus, if a six years’ rotation be thought the most profitable, there should be twelve inclosures, two of which are always under the same crop. One very obvious ad¬ vantage in this arrangement is, that it tends greatly to equalize labour, and, with a little attention, may contribute much to equalize the produce also. On large farms, where all the land under turnips and clover, for instance, is near the extremity of the grounds, or at a considerable dis¬ tance from the buildings, supposed to be set down near the centre, it is clear that the labour of supplying the house and straw-yard stock with these crops, as well as the carriage of the manure to the field, is much greater than if the fields were so arranged as that the half of each of these crops had been near the offices. But by means of two fields for each crop in the rotation, it is quite easy to connect together one field near the houses with another at a distance, and thus to have a supply at hand for the home stock, while the distant crops may be consumed on the ground. The same equalization of la¬ bour must be preserved in the cultivation of the corn fields and in harvesting the crops. The time lost in tra¬ velling to some of the fields, when working by the plough, is of itself a matter of some consequence on large farms. But the advantages of this arrangement are not confined to the equalization and economy of labour ; it may also in a great measure render the annual produce uniform and equable, notwithstanding a considerable diversity in the quality of the soil. A field of an inferior soil may be con¬ nected with one that is naturally rich; and in the con¬ sumption of the green crops, as well as in the allowance of manure, the poor land may be gradually brought nearer, in the quantity and quality of its produce, to the rich, without any injury to the latter. Thus, a field under tur¬ nips may be so fertile that it would be destructive to the succeeding corn crop to consume the whole or the greater part on the grbund; while another may be naturally so poor, or so deficient in tenacity, as to make it inexpedient to spare any part for consumption elsewhere. By connect¬ ing these two under the same crop,—by carrying from the one the turnips that are wanted for the feeding-houses and straw-yards, and eating the whole crop of the other on the ground with sheep, the ensuing crop of corn will not be so luxuriant on the former as to be unproductive, while the latter will seldom fail to yield abundantly. The same plan will also be advantageous in the case of other crops. Hay or green clover may be taken from the richer field, and the poorer one depastured; and on the one wheat may succeed both turnips and clover, while the more gentle crops of barley and oats are appropriated to the less fertile field. These observations are particularly applicable to turnip soils, of such a quality as not to require more than one year’s pasturage, and which are therefore cultivated with corn and green crops alternately; but the same principle may be extended to clay lands, and such as require to be depastured two or more years in succession. It is scarcely necessary to add, that upon wet soils, where hedges are employed as fences, it is of importance that the ditches be drawn in such a direction as to serve the purposes of drains, and also that they may receive the water from the covered drains that may be required in the fields contiguous. According as the line of the fence is more or less convenient in this respect, the expense of draining may be considerably diminished or increased. The most common fences, of a permanent character, are stone walls and white thorn hedges. Stone walls have a<- the recommendation of being an immediate fence, but t the disadvantage of going gradually to decay, and of re-^ quiring to be entirely rebuilt, in some cases every twenty years, unless they are constructed with lime mortar, which is in many districts much too expensive to be em¬ ployed in erecting common fences. White thorn hedges, on the contrary, though they require several years to be¬ come a fence of themselves, may be preserved at very little expense afterwards in full vigour for several gene¬ rations. Having thus thrown out a few hints of a general nature on this important subject, we shall only mention such of the fences as are in common use, and of a permanent character, without attempting to enumerate all the va¬ rieties and combinations which may be occasionally found in practice, or such as are only meant to serve a tempo¬ rary purpose. The two leading divisions, as just mentioned, are into Fen ii0 hedges and stone walls; to which are added in parti-comi, cular situations fences of iron, though these last are foruse/ the most part confined to gentlemen’s parks, and partake as much of ornament as utility. With regard to hedges, the plant in most common use is the white thorn, though we have seen very good hedges composed of beech, holly, and other plants; and it is not unusual to find a mixture of all these and others in many parts of England. The best hedges, however, are com¬ posed exclusively of the white thorn, which, when pro¬ perly managed, makes the most effectual and durable of all fences. Tire usual practice is to open a trench or ditch, and with the earth to form a bank, on the face of which thorns are planted almost in a horizontal direction, and w ith their tops protruding a few inches outwards; the bank being continued above the roots of the thorns to such a height as may be deemed necessary. And as a further protection, while the plants are young, a paling or a dead hedge is carried along the top of the bank, which makes an effectual fence at the very outset. When the thorns have growrn up to form a sufficient fence of themselves, the paling or dead hedge is no longer wanted. In some instances whins or furze are sown upon the bank, for the same purpose of protecting the young thorns, and render¬ ing the fence more complete. The dimensions of the ditch and the height of the bank are in a great measure arbitrary, depending upon the nature of the soil, and whether the ditch is or is not required for the purpose of draining the land. A double ditch is sometimes used, with a bank in the middle, and a row of thorns on each side; but in ordinary cases it is a great objection that this fence occupies so much space, besides being more expensive, both in forming and rearing, than the single fence. Stone walls are constructed of different dimensions, according to the purposes for which they are intended. The most common and generally useful for agricultural purposes are about five feet high, built close, and finished on the top with a coping of turf or long stones. Ihe latter are laid on edge, and project a little over the breadth of the wall, the interstices being filled up and closely packed with small stones. In some parts of Scot¬ land, what is called the Galloway Dyke is found to form a very cheap and useful fence on hilly grounds, where the inclosures are large. It is built close or double for about two feet from the ground, and then carried up to the height of four or four and a half feet with stones so placed as to admit of the light passing through the wall; and when any part of it falls down, it is easily repaired. Sheep, it is alleged, are deterred from leaping against such a AGRICULTURE. i\. fence, from its being thus open, more than they would be Au!" if it were built solid and of greater height. ^ A fence which combines in some measure the advan¬ tages of both the quick hedge and the stone wall, has been found to answer in situations where the soil is not well adapted to the ditch and hedge alone, and particu¬ larly where land stones are abundant, and there is a scar¬ city of wood for rails or paling. This fence is executed in the following manner: A ditch is formed, with one side of it perpendicular, or nearly so, and a facing of stone is then begun at the bottom and carried up regularly in the manner that stone walls are usually built, the space between the wall and the side of the bank being filled up with the earth taken out of the ditch, which should be of a good quality, and mixed with lime or compost. The thorns are then laid down in such a manner as that four inches or more of the root or stem shall rest upon the earth, the top of the plant projecting beyond the wall. They are then covered with earth, and the wall and the bank behind carried upwards as far as may be thought necessary. In this way the plants appear to grow from the face of the wall which affords them protection, and they are not so liable to be annoyed with weeds as if they had been planted on a bank of earth. But this method seems better adapted to an outside fence than to one for separating fields on either side, unless the wall be carried up by itself considerably above the height of the bank. (General Report of Scotland, vol. i.) We may add, that in many instances there seems to be a radical error in the first construction and subsequent management of hedge-fences in particular, which might be easily removed under appropriate covenants of lease. The expense of inclosing, and of course the direction and construction of the fences, ought to be undertaken in al¬ most every case by the proprietor, not merely for the sake of relieving the tenant from a burden which may be incompatible with his circumstances and professional du¬ ties, but also from a principle of economy on the part of the landlord. Whatever may be the tenant’s knowledge and capital, it is not to be expected that his views should extend much beyond his own accommodation during his temporary occupation ; whereas the permanent interest of the landlord requires, not so much a minute attention to economy in the first instance, as that the amelioration shall be as complete and as durable as possible. The tenant’s outlay on fences must inevitably be returned by a diminution of the yearly rent, and probably with a large profit for the first advance of the money; while, at the same time, that money may be expended in an improve¬ ment which is neither so complete nor so lasting as it might have been rendered had it been done at the ex¬ pense and under the direction of the proprietor. But another error of the same kind is probably still more common, and by far more pernicious to landholders. Ihe fences are to be kept in repair by the tenant; which, in so far as regards stone walls, is a stipulation no way objectionable. But it often happens that a landlord, even though he runs a hedge-fence at his own expense, leaves it to be trained up by the tenant without his interference; and the consequence is, that in perhaps nine cases out of ten, it never becomes a sufficient fence at all; that the original cost is lost for ever; and that the land which it occupies is not only unproductive, but actually a nuisance. Besides, it is evidently improper to require of a tenant to rcar up a good fence, commonly by a greater outlay than was required for forming it, when the half of his lease perhaps must elapse before he can derive much benefit f!i°m u' on the part of proprietors is proba- y the principal cause of the badness of hedge-fences; 275 for if they are neglected when the plants are young,—if Agricul- cattle are allowed to make gaps,—water permitted to ture. stagnate in the ditch,—or weeds to grow unmolested on the face of the bank, no labour or attention afterwards will ever make an equal and strong fence. As it is well known how difficult or rather impossible it is to enforce this care by any compulsory covenants, the best plan for both parties is that which is adopted in some districts, where hedges are reared at the mutual expense of land¬ lord and tenant,—the thorns, while they require it, being protected by rails, or otherwise, so as to give the tenant all the advantages of a complete fence in the mean time. In this case he cannot justly complain that he pays a share of the expense; and this payment furnishes the strongest motive for preserving the young thorns from damage, and for training them with such care as to be¬ come a complete fence in the shortest possible period. The provisions of the law of Scotland in regard to in- Laws re¬ closing have greatly promoted this invaluable improve-garding ment. It holds out the greatest facilities, both for fences, straightening the boundaries of conterminous properties, and for erecting march-fences, by obliging every proprie¬ tor, upon due notice from his neighbour, to defray half the charges of such a fence as the nature of the soil and surface may render most eligible. By an act in 1686, cattle must bo constantly herded during the day, if the pastures be not inclosed, and are ordered to be kept dur¬ ing the night in houses, folds, or inclosures; a fine is ex¬ igible from the owner if his cattle trespass on his neigh¬ bour’s lands,—so much for every animal,—over and above the damage done, even where there are no fences; and, by the statute 1695, heavy penalties are denounced against such as destroy fences. As connected with the subject of fences and other ru- Odometer, ral works, though applicable to many other purposes, we may notice an instrument called the Odometer, exhibited a few years ago to the Highland Society of Scotland by Mr Hunter of Thurston, of which figures will be found in Plate IX. By merely walking from one end to the other of any wall, road, hedge, ditch, &c. with this instrument, which is not more troublesome than a walking-stick, the length is found much more correctly than by a measuring chain, and with much greater expedition. Mr Hunter has one so constructed as to measure nearly 1300 miles, which may be attached to the wheel of any carriage, and will measure the road passed along at any rate of travelling. Sect. IV. Tillage. As the operations connected with tillage must necessa- General rily be regulated by the condition of the soil and surface, observa- and the crops to be cultivated, as to which we shall tions. have occasion to treat in a subsequent section, all that is at present necessary is, to offer a few general observations, premising that we here take it for granted, that all those obstructions which fall to be considered under the chapter on Natural Pastures and Wastes, have either never exist¬ ed, or been already removed. It is well known to every husbandman, that clayey or tenacious soils should never be ploughed when wet; and that it is almost equally improper to allow them to be¬ come too dry, especially if a crop is to be sown without a second ploughing. The state in which such lands should be ploughed is that which is commonly indicated by the phrase, “between the wet and the dry,”—while the ground is slightly moist, mellow, and the least cohesive. In ploughing the first time for fallow or green crops, \yinter all good farmers begin immediately after harvest, or after ploughing. 276 AGRICULTURE. Awricul- ture. Different modes of wheat sowing is finished; and when this land has been gone over, the old tough swards, if there be any, are next turned up. The reasons for ploughing so early are suf¬ ficiently obvious; as the frosts of winter render the soil more friable for the spring operations, and assist in de¬ stroying the weed-roots. In some places, however, the first ploughing for fallow is still delayed till after the spring seed-time. In the following remarks, the swing-plough, drawn by two horses, is to be understood as the one employed, if no other be mentioned; and we shall here confine ourselves for the most part to the practice of the north of England and the south-east of Scotland. Three different points require particular attention in ploughing: I. the breadth of the slice to be cut; 2. its depth; and 3. the degree in which it is to be turned over;—which last circumstance depends both upon the construction of the plough, particularly the mould-board, and the care of the ploughman. The breadth and depth of the furrow-slice are regulat¬ ed by judiciously placing the dx*aught on the nozzle or bridle of the plough; setting it so as to go more or less deep, and to take more or less land or breadth of slice, according as may be desired. In general, the plough is so regulated that, if left to itself, and merely kept from falling over, it would cut a little broader and a little deep¬ er than is required. The coulter is also placed with some inclination towards the left or land side, and the point of the sock or share has a slight tendency downwards. The degree to which the furrow-slice turns over, is in a great measure determined by the proportion between ploughing. jts brea(Jth and depth, which for general purposes is usu¬ ally as three is to two; or when the furrow is nine inches broad, it ought to be six inches in depth. When the slice is cut in this proportion, it will be nearly half turned over, or recline at an angle of 40 or 45 degrees; and a field so ploughed will have its ridges longitudinally ribbed into angular drills or ridgelets. But if the slice is much broad¬ er in proportion to its depth, it will be almost completely overturned, or left nearly flat, with its original surface downwards; and each successive slice will be somewhat overlapped by that which was turned over immediately before it. And finally, when the depth materially exceeds the width each furrow-slice will fall over on its side, leaving all the original surface bare, and only laid some¬ what obliquely to the horizon. The first of these modes of ploughing, where the breadth and depth are nearly in the proportion already mentioned, is the best adapted for laving up stubble land after harvest, when it is to remain during winter exposed to the mellowing influence of frost, preparatory to fallow or turnips. The second or shallow furrow, of considerable width, as five inches in depth by eight or nine wide, is understood to answer best for breaking up old leys, be¬ cause it covers up the grass turf, and does not bury the manured soil. The third is a most unprofitable and use¬ lessly slow operation, which ought seldom or never to be adopted. The most generally useful breadth of a furrow- slice is from eight to ten inches, and the depth, which ought to be seldom less than four inches, cannot often ex¬ ceed six or eight inches, except in soils uncommonly thick and fertile. When it is necessary to go deeper, as for carrots and some other deep-rooted plants, a trench- ploughing may be given by means of a second plough fol¬ lowing in the same furrow. Shallow ploughing ought al¬ ways to be adopted after turnips are eaten on the ground, that the manure may not be buried too deep; and also in covering lime,—especially if the ground has been pulver¬ ized by fallowing, because it naturally tends to sink in the o soil. In ploughing down farm-yard dung, it is commonly Ag i necessary to go rather deep, that no part of the manure t may be left exposed to the atmosphere. In the first '*' ploughing for fallow or green crops, it is advisable to work as deep as possible ; and no great danger is to be apprehended, though a small portion of the subsoil be at that time brought to the surface. The furrow-slices are generally distributed into beds,Lan varying in breadth according to circumstances ; these areridg called ridges or lands, and are divided from one another by gutters or open furrows. These last serve as guides to the hand and eye of the sower, to the reapers, and also for the application of manures in a regular manner. In soils of a strong or retentive nature, or which have wet, close subsoils, these furrows serve likewise as drains for carrying off the surface water; and being cleared out after the land is sown and harrowed, have the name of water-furrows. Ridges are not only different in breadth, but are raised more or less in the middle on different soils. On clayey, retentive soils, the great point to be attended to is the discharge of superfluous water. But narrow stitches of from three to five feet are not approved of in some of the best cultivated counties. In these a breadth of fifteen or eighteen feet, the land raised by two gatherings of the plough, is most commonly adopted for such soils; such a ridge being thought more convenient for manuring, sow¬ ing, harrowing, and reaping, than a narrower one; and the water is drained off quite as effectually. On dry, porous turnip soils, ridges may be formed much broader ; and were it not for their use in directing the la¬ bourers, may be, and sometimes are, dispensed with alto¬ gether. They are often thirty or thirty-six feet broad, which in Scotland are called hand-win ridges, because reaped by a band of shearers, commonly six, served by one binder. If it be wished to obliterate the intermediate furrows, this may be done by casting up a narrow ridgelet or single-bout drill between the broad ridges, which is af¬ terwards levelled by the harrows. With regard to the mode of forming these ridges straight and of uniform breadth, let us suppose a field perfectly level that is intended to be laid off' into ridges of any determinate breadth. The best ploughman be¬ longing to the farm conducts the operation, with the aid of three or more poles shod with iron, in the following manner: the first thing is to mark off the head ridges, on which the horses turn in ploughing, which should in gene¬ ral be of an equal breadth from the bounding lines of the field, if these lines are not very crooked or irregular. The next operation, assuming one straight side of the field, or a line that has been made straight, as the proper direction of the ridges, is to measure off from it with one of the poles (all of them of a certain length, or expressing specific measures) half the intended breadth of the ridge if it is to be gathered, or one breadth and a half if to be ploughed flat; and there the ploughman sets up a pole as a direction for the plough to enter. On a line with this, and at some distance, he plants a second pole, and then in the same manner a third, fourth, &c. as the irregularity of the surface may render necessary, though three must al¬ ways be employed,—the last of them at the end of the intended ridge, and the whole in one straight line. He then enters the plough at the first pole, keeping the line of poles exactly between his horses, and ploughs down all the poles successively; halting his horses at each, and re¬ placing it at as many feet distant as the ridges are to be 1 - -i ■ v , > 1 " ■* --J—* all broad; so that when he reaches the end of the ridge, his poles are again set up in a new line parallel to the first. He returns, however, along his former track, cor- AGRICULTURE. 277 .1- reeling any deviations, and throwing a shallow furrow on M the side opposite to his former one. These furrows, when ✓v**'reversed, form the crown of the ridge, and direct the ploughmen who are to follow. The same operations are carried on until the whole field is marked out. This is called/chYW# in Scotland, and striking ike farrows in Eng¬ land. It is surprising with what accuracy these lines are drawn by skilful ploughmen. Another method has been adopted for the same pur¬ pose, which promises to be useful with less experienced workmen. A stout lath or pole, exactly equal in length to the breadth of the intended ridge, is fixed to the plough at right angles to the line of the draught, one end of which is placed across the handles exactly opposite the coulter, while the other end projects towards the left hand of the ploughman, and is preserved in its place by a rope passing from it to the collar of the near side horse. At the outer end of the lath, a coulter or harrow tine is fixed perpen¬ dicularly, which makes a trace or mark on the ground, as the plough moves onwards, exactly parallel to the line of draught. By this device, when the plough is feiring the crown of one ridge, the marker traces the line on which the next ridge is to be feired. ( General Report of Scot¬ land, vol. i. p. 3oT) With regard to the direction and the length of ridges, these points must evidently be regulated by the nature of the surface and the size of the field. Short angular ridges, called butts, which are often necessary in a field with irregular boundaries', are always attended with a con¬ siderable loss of time, and ought to be avoided as much as possible. In ploughing steep land it is advisable to give the ridges an inclination towards the right hand at the top, by which in going up the acclivity the furrow falls more readily from the plough, and with less fatigue to the horses. Another advantage of forming ridges in a slanting direc¬ tion on such land is, that the soil is not so apt to be wash¬ ed down from the higher ground, as if the ridges were laid at right angles. Wherever circumstances will permit, how¬ ever, the best direction is due north and south, by which the grain on both sides of the ridge derives nearly equal advantages from the influence of the sun. The land being thus formed into ridges, is afterwards cultivated without marking out the ridges anew, until the inter-furrows have been obliterated by a fallow or fallow crop. This is done by one or other of the following modes ^rewind of ploughing:—1. If the soil be dry and the land has been lu , P^^hed flat, the ridges are split out in such a way, that 01 the space which the crown of the old ridge occupied is now allotted to the open furrow between the new ones, lids is technically called crown-and-farrow ploughing. 2. When the soil is naturally rather wet, or if the ridges have been raised a little by former ploughings, the form of the old ridges, and the situation of the inter-furrows, are preserved by what is called casting ; that is, the1 fur¬ rows of each ridge are all laid in one direction, while those of the next adjoining ridge are turned the contrary ng-way; two ridges being always ploughed together. 3. It is commonly necessary to raise the ridges on soils very tenacious of moisture, by what is called gathering, which is done by the plough going round the ridge, beginning at the crown and raising all the furrow-slices inwards, ■k I his last operation, when it is wished to give the land a level surface, as in fallowing, is reversed by turning all the furrow-slices outwards, beginning at the inter-furrows, and leaving an open furrow on the crown of each ridge. In order to bring the land into as level a state as possible, the same mode of ploughing, or cleaving, as it is called, may be repeated as often as necessary. iasti:. I' 1 Cleav v, High crooked ridges are universally disapproved of, Agricul- and are now very rare in the best cultivated districts. A ture. machine employed in levelling such land is exhibited in'^v'^~/ Plate X.; and a reward was given by the Society of Arts LevellinR- in London for the improvements made on it by Mr David Charles in 1803, On strong lands, a pair of good horses ought to plough Extent three quarters of an acre in nine hours; but upon the ploughed same land, after the first ploughing, or on friable soils, one^ two acre or an acre and a quarter is a common day’s work.1101’868. Throughout the year an acre a day may be considered as a full average on soils of a medium consistency. The whole series of furrows on an English statute acre, sup¬ posing each to be nine inches broad, would extend to 19,360 yards; and adding twelve yards to every 220 for the ground travelled over in turning, the whole work of one acre may be estimated as extending to 20,416 yards, or eleven miles and nearly five furlongs. A kind of ploughing known by the name of ribbing was Ribbing, formerly common on land intended for barley, and was executed soon after harvest, as a preparation for the spring ploughings. A similar operation is still in use in some places, after land has been pulverized by clean ploughings, and is ready for receiving the seed. By this method only half the land is stirred, the furrow being laid over quite flat, and covering an equal space of the level surface. But except in the latter instance, where corn is meant to grow in parallel lines, and where it is used as a substitute for a drill-machine, ribbing is highly objec¬ tionable, and has become almost obsolete. Sect. V. Fallowing. There is no branch of agricultural practice that has en-Opinions gaged more attention of late than this; and after many pf fallow- years’ controversy, in which some of the ablest cultivators in*>' of the present day have entered the lists, and exhausted perhaps all the legitimate arguments on both sides, the practice does not appear to give way, but rather to extend, on wet, tenacious clays; and it is only on such that any one contends for the advantages of fallowing. The expe¬ diency or inexpediency of pulverizing and cleaning the soil by a bare fallow, is a question that can be determined only by experience, and not by argument. No reasons, however ingenious, for the omission of this practice, can bring conviction to the mind of a farmer who, in spite of all his exertions, finds, at the end of six or eight years, that his land is full of weeds, sour, and comparatively unpro¬ ductive. Drilled and horse-hoed green crops, though cul¬ tivated with advantage on almost every soil, are probably in general unprofitable as a substitide for fallow, and after a time altogether inefficient. It is not because turnips, cabbages, &c. will not grow in such soils, that a fallow is resorted to, but because, taking a course of years, the value of the successive crops is found to be so much greater, even though an unproductive year is interposed, as to induce a preference to fallowing. Horse-hoed crops of beans, in particular, postpone the recurrence of fallow, but in few situations can they ever exclude it altogether. On the other hand, the instances that have been ad¬ duced of a profitable succession of crops on soils of this description, without the intervention of a fallow, are so well authenticated, that it would be extremely rash to assert that it can in no case be dispensed with on clay soils.. Instances of this kind are to be found in different parts of Mr Young’s Annals of Agriculture ; and a very notable one, on Mr Greg’s farm of Coles, in Hertfordshire, is ac¬ curately detailed in the sixth volume of the Communica¬ tions to the Board of Agriculture. 278 AGRICULTURE. Agricul¬ ture. The principal causes of this extraordinary difference (among men of great experience may probably be found in the quality of the soil, or in the nature of the climate, or, in both. Nothing is more vague than the names by which soils are known in different districts. Mr Greg’s farm in particular, though the soil is denominated “ heavy arable land,” and “ very heavy land,” is found so suitable to tur¬ nips, that a sixth part of it is always under that crop, and these are consumed on the ground by sheep—a system of management which every farmer must know to be alto¬ gether impracticable on the wet, tenacious clays of other districts. It may indeed be laid down as a criterion for determining the question, that wherever this management can be profitably adopted, fallow, as a regular branch of the course, must be not less absurd than it is injurious both to the cultivator and to the public. It is probable, therefore, that in debating this point, the opposite parties are not agreed about the quality of the soil, and in parti¬ cular about its property of absorbing and retaining mois¬ ture, so different in soils that in common language have the same denomination. Another cause of difference must be found in the cli¬ mate. It is well known that a great deal more rain falls on the west than on the east coast of Britain, and that between the southern and northern counties there is at least a month or six weeks’ difference in the maturation of the crops. Though the soil therefore be as nearly as pos¬ sible similar in quality and surface, the period in which it is accessible to agricultural operations must vary accord¬ ingly. Thus, in the south-eastern counties of the island, where the crops may be all cut down, and almost all car¬ ried home by the end of August, much may be done in cleansing and pulverizing the soil during the months of September and October, while the farmers of the north are exclusively employed in harvest work, which is fre¬ quently not finished by the beginning of November. In some districts in the south of England wheat is rarely sown before December; whereas in the north, and still more in Scotland, if it cannot be got completed by the end of October, it must commonly be delayed till spring, or oats or barley be taken in place of wheat. It does not then seem of any utility to enter farther into this controversy, which every skilful cultivator must determine for himself. All the crops, and all the modes of management which have been proposed as a substitute for fallow, are well known to such men, and would un¬ questionably have been generally adopted long ago, if, upon a careful consideration of the advantages and dis¬ advantages on both sides, a bare fallow was found to be unprofitable in a course of years. The reader who wishes to examine the question fully may consult, among many others, the works noted below.1 However necessary the periodical recurrence of fallow may be on retentive clays, its warmest advocates do not recommend it on turnip soils, or on any friable loams in¬ cumbent on a porous subsoil; nor is it in any case neces¬ sary every third year, according to the practice of some districts. On the best cultivated lands it seldom returns oftener than once in six or eight years, and in favourable situations for obtaining an extra-supply of manure, it may be advantageously dispensed with for a still longer period. Fallows are in many instances so grossly mismanaged, particularly where they recur so often as to make it an object to derive some profit from them by means of sheep, that it may be of use to describe the several operations A according to the justly esteemed practice of East Lothian and Berwickshire. ^ “ Invariably after harvest, the land intended for being f summer-fallowed in the ensuing year gets an end-lontrde! ploughing, which ought to be as deep as the soil will a£ mit, even though a little of the till or subsoil is brought up. This both tends to deepen the cultivated or manured soil, as the fresh accession of hitherto uncultivated earth becomes afterward incorporated with the former manured soil, and greatly facilitates the separation of the roots of weeds during the ensuing fallow process, by detachino- them completely from any connection with the fast sub¬ soil. This autumnal ploughing, usually called the win¬ ter furrow, promotes the rotting of stubble and weeds • and if not accomplished towards the end of harvest, must be given in the winter months, or as early in the sprint as possible. In giving this first ploughing, the old ridges should be gathered up, if practicable, as in that state they are kept dry during the winter months; but it is not un¬ common to split them out or divide them, especially if the land had been previously highly gathered, so that each original ridge of land is divided into two half-ridges. Sometimes, when the land is easily laid dry, the furrows of the old ridges are made the crowns of the new ones, or the land is ploughed in the way technically called crown-and-fur. In other instances, two ridges are ploughed together by what is called casting, which has been already described. After the field is ploughed, all the inter¬ furrows, and those of the headlands, are carefully opened up by the plough, and are afterwards gone over effectual¬ ly by a labourer with a spade, to remove all obstructions, and to open up the water furrows into the fence ditches, wherever that seems necessary, that all moisture may have a ready exit. In every place where water is ex¬ pected to lodge, such as dishes or hollow places in the field, cross or oblique furrows are drawn by the plough, and their intersections carefully opened into each other by the spade. Wherever it appears necessary, cross cuts are also made through the head ridges into the ditches with a spade, and every possible attention is exerted that no water may stagnate in any part of the field. “ As soon as the spring seed-time is over, the fallow land is again ploughed end-long. If formerly split, it is now ridged up; if formerly laid up in gathered ridges, it is split or cloven down. It is then cross-ploughed; and after lying till sufficiently dry to admit the harrows, it is harrowed and rolled repeatedly, and every particle of the vivacious roots of weeds brought up to view, carefully gathered by hand into heaps, and either burnt on the field or carted off to the compost midden. The fallow is then ridged up, which places it in a safe condition in the event of bad weather, and exposes a new surface to the harrows and roller; after which the weeds are again gathered by hand, but a previous harrowing is necessary. It is after¬ wards ploughed, harrowed, rolled, and gathered as often as may be necessary to reduce it into fine tilth, and com¬ pletely to eradicate all root-weeds. Between these suc¬ cessive operations, repeated crops of seedling weeds are brought into vegetation and destroyed. The larvae like¬ wise of various insects, together with an infinite variety of the seeds of weeds, are exposed to be devoured by birds, which are then the farmer’s best friends, though often proscribed as his bitterest enemies. Some writers on husbandry have condemned the use :ul. vlZTAfXuUnfal X A?r;CultnZ' an? ^ritings generally; Hunter’s Georgical Essays; Dickson’s Practical Agriculture; Sir H- Davy s Agricultural Chemistry; Brown’s Treatise on Rural Affairs; The County Reports; and The General Report of Scotland. agriculture. 279 am.!, of the harrow and roller in the fallow process, alleging peas, beans, tares, &c. but also to the different ,• , . »- of herbage, as well as turnips, po" es and ™her Sre' S01, «** «wo divisions root-weeds, by the baking or drying of the clods in the gun and wind; but experience has ascertained, that fre¬ quently turning over the ground, though absolutely ne¬ cessary while the fallow process is going on, can never eradicate couchgrass or other root-weeds. In all clay soils the ground turns up in lumps or clods* which the severest drought will not penetrate so sufficiently as to kill the included roots. When the land is again ploughed, these lumps are simply turned over and no more, and the action of the plough serves in no degree to reduce them, or at least very imperceptibly. It may be added, that these lumps likewise inclose innumerable seeds of weeds, which cannot vegetate unless brought under the influence of the sun and air near the surface. The diligent use, therefore, of the harrow and roller, followed by careful hand-picking, is indispensably necessary to the perfection of the fallow process.” (General Report of Scotland, vol. i. p. 419.) When effectually reduced to fine tilth, and thoroughly cleansed from roots and weeds, the fallow is ploughed end-long into gathered ridges or lands, usually 15 or 18 feet broad, which are set out in the manner already de¬ scribed in treating of the striking of furrows, or feiring. If the seed is to be drilled, the ridges are made of such widths as may suit the construction of the particular drill- machine that is to be employed. After the land has been once gathered by a deep furrow, proportioned to the depth of the cultivated soil, the manure is laid on, and evenly spread over the surface, whether muck, lime, marl, or compost. A second gathering is now given by the plough; and this being generally the furrow upon which the seed is sown, great care is used to plough as equally as possible. After the seed is sown and the land tho¬ roughly harrowed, all the inter-furrows, furrows of the headlands, and oblique or furrows, are carefully opened up with the plough, and cleared out writh the spade, as already mentioned respecting the first or winter ploughing. The expense of fallowing must appear, from what has been said, to be very considerable, when land has been allowed to become stocked with weeds; but if it be kept under regular management, corn alternating with drilled pulse or green crops, the subsequent returns of fallow will not require nearly so much labour. In common cases, from four to six ploughings are generally given, with har¬ rowing and rolling between, as may be found necessary; and, as we have already noticed, the cultivator may be employed to diminish this heavy expense. But it must he considered, that upon the manner in which the fallow operations are conducted depends not only the ensuing wheat crop, but in a great measure all the crops of the rotation. Sect. VI. Of THE DIFFERENT KINDS OF CROPS. ^e. C1’°ps cultivated in Britain present every variety of which the soil and climate will admit; and in an agri- cu tural point of view may be considered under several 1 'visions, according to their nature, or the purposes for ",Hc 1 tllcy are intended. The most popular arrangement p aces all sorts of farm crops under the two general heads o corn and green crops ; the former applicable to the use 0 man> and fhe latter to that of cattle, sheep, and other 'aneties of live stock. The former include the different eerealia, of which the most important are wheat, barley, r}c, and oats. The latter, or green crops, comprise a still eater variety, the words being, in common language, aPP led not only to pulse or leguminous plants, such as is, that corn or other culmiferous plants riplning1 their seeds are held to be scourging crops, whereas those that fall under the denomination of green crops are considered to be of an ameliorating description, or at least as not impairing the productive powers of the soil in the same degree. As it is our object to treat only of matters of practi- ca utility, we shall not attempt any scientific arrangement but content ourselves with describing the principal crops’ with their mode of culture, produce, and application, in popular language, confining our remarks at present chiefly to such as are cultivated from year to year, as distin¬ guished from those which, like the pasture grasses, are intended to occupy the soil permanently or for an inde¬ finite period. Of these by far the most important is, 1. Wheat. The soil best adapted to this grain is a clay or strong Wheat, loam, though its growth is by no means confined to such soils. Before the introduction of turnips and clover, all soils but little cohesive were thought quite unfit for wheat; but, even on sandy soils, it is now grown extensively and with much advantage after either of these crops. The greater part of the wheat crop throughout Britain, how¬ ever, is probably still sown upon fallowed land. When it succeeds turnips consumed on the ground, or clover cut for hay or soiling, it is commonly sown after one plough¬ ing ; but, upon heavier soils, or after grass of two or more years, the land is ploughed twice or three times, or re¬ ceives what is called a rag-falloiv. The varieties of this grain are so numerous as not to Varieties, admit of being enumerated here; but the most general classification is according to colour, all the varieties being divided into white and red, though with several shades between; or according to the time which the grain re¬ quires to remain in the ground, being either sown before winter, or in the spring months ; and hence the distinction between winter and spring or summer wheat. But this last variety must not be confounded with the winter wheats, which are sometimes sown in spring. Several other dif¬ ferences in wheat are sufficiently obvious: thus, the true summer wheat is usually bearded, and some of the winter varieties are distinguished by being woolly-eared, or by the thickness of the chaff; all which and other peculiarities give rise to different names, which are sufficiently under¬ stood in particular districts, though not in general use. The fine white wheats are considered more delicate than the red; but the latter, though seldom sown on rich warm soils, are found most profitable, from their hardiness and early ripening, on inferior land, in an unfavourable climate. A great many different sorts of summer wheat, transmitted some years ago to the president of the Board of Agriculture by the Agricultural Society of Paris, were divided, for the purpose of experiment, among several distinguished agriculturists ( Communications to the Board of Agriculture, vol. vii. page 11); but their comparative merits, or adaptation to the climate of Britain, do not seem to have been satisfactorily ascertained. Summer, or, as it is often called, spring wheat, has, however, been long and extensively cultivated in some parts of England, particularly in Lincolnshire, and may probably be found a valuable crop in the southern counties; but the trials that have been made of it in the north do not entitle it to a preference over winter wheat sown in spring, or even to oats or barley, in that climate. It is sometimes usefully employed in filling up any blanks that appear in spring among the winter-sown wheats 280 AGRICULTURE. Prepara, tion of seed. Agricul- Winter wheat is sown on early turnip soils, after clover ture. or turnips, at almost every period from the beginning of September till the middle of March; but the far greater part is sown in September and October. For summer wheat, in the southern districts, May is sufficiently early; but in the north, the last fortnight of April is thought a more eligible seed-time. In the cultivation of spring- sown winter wheat, it is of importance to use the produce of spring-sown grain as seed, as the crop of such grain ripens about a fortnight earlier than when the produce of the same wheat winter-sown is employed as spring seed. Wheat, before being sown, is usually prepared with pickles or steeps and quicklime, as a preventive of smut. We shall only add a short account of a method of prepa¬ ration which has been followed with success in the south of Scotland, and of the efficacy of which we can speak from our own experience. Take four vessels, two of them smaller than the other two, the former with wire bottoms, and of a size to contain about a bushel, the latter large enough to hold the smaller within them. Fill one of the large tubs with water, and, putting the wheat in a small one, immerse it in the water, and stir and skim off the grains that float above; and renew the water as often as is necessary, till it comes off almost quite clean. Then raise the small vessel in which the wheat is contained, and repeat the process with it in the other large tub, which is to be filled with stale urine; and in the mean time wash more wheat in the water tub. When abun¬ dance of water is at hand, this operation is by no means tedious ; and the wheat is much more effectually cleansed from all impurities, and freed more completely from weak and unhealthy grains and the seeds of weeds, than can be done by the winnowing-machine. When thoroughly washed and skimmed, let it drain a little, then empty it on a clean floor, or in the cart that is to take it to the field, and riddle quicklime upon it, turning it over, and mixing it with a shovel, till it be sufficiently dry for sowing. Broad-cast Wheat is most commonly sown broad-cast, in a manner and drill too well known to need any description. Drilling is, how- sowing. ever, extensively practised in some districts, and is becom¬ ing more general on lands infested with the seeds of annual weeds, especially when sown in spring. A machine which sows at three different intervals, according to the judg¬ ment of the farmer, of 12, 101, 0r 9 inches, is much ap¬ proved of in Scotland. It deposits six, seven, or eight rows at once, according as it is adjusted to one or other of these intervals, and the work is done with ease and accuracy when the ridges are previously laid out of such a breadth, 12^- feet, as to be sown by one bout; the machine going along one side of such a ridge, and returning on the other, and its direction being guided by one of its wheels, which thus always runs in the open furrow between the ridges. If the 101 incb interval be adopted, and it is the most common one in that country, the machine sows seven rows at once, or 14 rows on a ridge of 121 feet. But the space between the rows varies in some parts still more than this machine admits of; it ought not, however, to be so narrow as to prevent hand-hoeing, even after the crop has made considerable progress in growth ; and it cannot advantage¬ ously be so wide as to admit the use of any effective horse-hoe. Sowing on A third mode of sowing is common in some places, by ribbs. which a drill-machine is dispensed with, though the same purpose is nearly answered. This is by what is called ribbing, which we have already adverted to in the section on tillage. The seed is scattered with the hand in the usual broad-cast manner, but as it necessarily falls for the most part in the furrows between the ribbs, the crop rises in straight parallel rows, as if it had been sown by a drill- machine ; and the ribbs are afterwards levelled by bar. rowing across them. This plan has nearly all the advan¬ tages of drilling, in so far as regards exposure to the rays1' A! of the sun, and the circulation of air among the plants- ' * but, as some plants must always rise between the rows it is not quite so proper when hand-hoeing is required. The dibbling of wheat is practised to some extent inp the county of NoiTolk, and occasionally in other quarters though it is perhaps too laborious and tedious a process in our unsteady climate ever to come into general use. An expert dibbler, with the assistance of three children to drop the grains, goes over about half an acre a day; and the seed, which is usually from one bushel to six pecks per acre, is covered by means of a bush-harrow. The prin¬ cipal, if not the only advantage that attends this method is the saving of seed. An attempt was made to employ a machine for the purpose, but it has never come into use. We have seen a field of which a part was sown broad-cast and a part dibbled, for the purpose of comparison; and the latter certainly appeared at the time more equal and luxu- riant than the former, but it had no superiority in point of produce, except perhaps that it contained a less propor¬ tion of small grains, or presented altogether a more equal sample. The quantity of seed necessary depends both on theQ time of sowing and the state of the land; land sown early of [' requiring less than the same land when sown in winterer spring, and poor land being at all times allowed more seed than the rich. The quantity accordingly varies from two bushels or less to three, and sometimes even to four bushels per imperial acre. Winter wheat, when sown in spring, ought always to have a liberal allowance, as the plants have not time to tiller much without unduly retarding their maturation. When wheat is sown broad-cast, the subsequent culture Ai must generally be confined to harrowing, rolling, andtu hand-hoeing. As grass-seeds are frequently sown in spring on winter-sown wheat, the harrows and roller are employed to loosen the soil and cover the seeds. But these operations, to a certain extent, and at the pro¬ per season, are found beneficial to the wheat crop itself, especially on strong clays, and are sometimes performed even when grass-seeds are not to be sowm. One or two courses of han'owing penetrate the crust which is formed on tenacious soils, and operate like hand-hoeing in raising a fresh mould to the stems of the young plants. Rolling in spring ought never to be omitted on dry, porous soils, which are frequently left in so loose a state by the winter frosts, that the roots quit the soil and perish ; and if the land be rough and cloddy, the roller has a still more bene¬ ficial effect than the harrows in pulverizing the inert masses, and extending the pasture of the plants. Hand- weeding, so far as to cut down thistles and other long weeds, is never neglected by careful farmers; but the previous culture ought to leave as little as possible of this work to be done when the crop is growing. Annual weeds, which are the most troublesome, can only be effectually destroyed by hand-hoeing ; and to admit of this, the crop should be made to rise in rows, by being sown either by a drill-machine, or on ribbs. Where grass-seeds are to be sown on drilled wheat, the hand-hoeing assists in covering them. < Wheat, which is almost universally reaped with theKi ?■ sickle, ought not to stand till it be what is called dead ripe, when the loss is considerable, both upon the field and in the stack-yard. When cut, it is usually tied up m sheaves, which it is better to make so small as to be done by bands the length of the straw, than so thick as to re¬ quire two lengths to be joined for bands. The sheaves nil. i _ri J. are set up in shocks or stocks, each containing in all twelve, tui or, if the straw be long, fourteen sheaves. In the latter yv^nase, two rows of six sheaves are made to stand in such a hock [ousi. id sU ireeh*'. AGRICULTURE. 281 Agricul¬ ture. — — ~ manner as to be in contact at the top, though, in order to admit the circulation of air, at some distance below; and along this line two sheaves more are placed as a covering, the corn end of both being towards the extremities of the line. In a few days of good weather the crop is ready for ■ the barn or stack-yard. In the stack-yard, which is com¬ monly contiguous to the farm-offices, having the barn on one of its sides, it is built either in oblong or circular stacks, sometimes on frames supported with pillars, to pre¬ vent the access of vermin, and to secure the bottom from dampness; and as soon afterwards as possible the stacks are neatly thatched. When the harvest weather is so wet as to render it difficult to prevent the stacks from heating, it has been the practice to make funnels through them, a of a boy. The value of the work of eight horses for a day may be stated at 30 shillings, and the wages of the chivei may be called two shdhngs and sixpence. Hence the total expense of threshing 250 bushels may amount to about twopence per bushel, when the wages of the attendants are added; still leaving a considerable differ- ence in favour of threshing by the machine in preference to the nail. W ere it even ascertained that the expense of threshing by horses and by the flail is nearly the same, horse-mills are to be recommended on other ac- c®UI?,t® ;.sucl1 as better threshing, expedition, little risk ot pilfering, &c. 1 he produce of this crop, like that of most others, ne-Produce cessaruy depends mainly upon the nature of the soil and season.

A particular method of constructing pillars, frames, and bosses, as the funnels are called, is described in a recent publication. (Husbandry of Scotland, vol. i. p. 373.) In the best cul¬ tivated counties, the use of large barns for holding the crop is disapproved of, not only on account of the expense, but because corn keeps better, or is less exposed to damage of any kind, in a well-built stack. By means of the threshing-mill all sorts of corn are ex¬ peditiously separated from the straw and dressed for mar¬ ket. One man feeds the grain in the straw into the machine, and is assisted by two half-grown lads, or young women, one of whom pitches or carries the sheaves from the bay close to the threshing-stage, while the other opens the bands of every sheaf, and lays the sheaves successive¬ ly on a small table close by the feeder, who spreads them evenly on the feeding-stage, that they may be drawn in successively by the fluted rollers, to undergo the ope¬ ration of threshing. In the opposite end of the barn or straw-house into which the rakes or shakers deliver the clean threshed straw, one man forks up the straw from the floor to the straw-mow, and two lads, or young women, average cannot perhaps be safely stated higher through¬ out any one county than from 3 to 31 quarters, the weight varying from 54 to 62 or 64 lbs. per bushel. The weight of the straw, which may run from a ton to a ton and half per acre, is used for thatch, packing, and, in the country, chiefly for litter to the live stock. The season best adapted for wheat is universally under¬ stood to be a summer in which there is much sunshine and little rain. Both in regard to quantity and quality, the crop is always best in a season rather too dry and hot for some other crops, the produce being then usually much greater than the bulk of the straw would lead one to expect. heat is liable to a variety of diseases, particularly in Diseases the more advanced stages of its growth. Of these the most destructive are smut and mildew. The former appears Smut, in the shape of a black or smut ball (lycoperdon globosuni), which partially occupies the ear of the stalk, to the exclu¬ sion of the grain, and so far lessens the quantity of pro¬ duce. But its worst effect is, that when the ball crumbles into powder in the threshing and dressing, this powder contaminates more or less all the sound grain, and thus build it md trppd It ~ ‘^'7^ ""‘“T’ Sreatly injures the quality of the whole, whether it be con- u kt it and tread it down. _ In a threshing-machine work- verted into flour or used as seed.

Bear, or bigg, is an earlier, as well as a hardier kind, than the two-rowed barley, and may be sown later. Winter-sown barley, which may be eaten in spring and afterwards stand for a crop, is found to answer well in particular districts. On land infested with annual weeds, the drilling of this grain is an advantageous practice; but throughout the coun¬ try at large, this, and all other culmiferous crops, are more generally sown broad-cast If the land be rich, a small quantity of seed is sufficient; often so little as two bushels per acre, and seldom more than three or three and aCL half; and its produce varies from three to five quartersd the acre, and may average four quarters. The chief con¬ sumption is in the distilleries and breweries; but in the north of England, and in Scotland, it is partially used for bread, either by itself, or mixed up with a small proportion of beans or peas, though much less so now than formerly. Part of it is made into what are called pot barley and pearl barley, in which the husk is taken off at the mill; and, in the latter case, so much of the kernel as to give it a round form. It is also occasionally ground into flour by taking out the bran, and in this state made into cakes, which are much esteemed in some parts of Scotland. Barley, like wheat, is most productive in a dry, warm season. For this reason, what is grown in the south of England is almost always superior to the produce of the northern parts of the island. It is not, like wheat, liable to any peculiar disease ; and is, of all the corn-crops, the best nurse for clover, which, under good management, is usually sown along with it. The straw of this grain, which may' weigh upon an average about a ton per acre, is used chiefly as litter for live stock. Barley is cut down in some places with the sickle, and! in others with the scythe; in England, very commonly with the latter, and in Scotland, almost always with the former. It is the most difficult of all the species of corn to save in a precarious harvest, and usually requires more labour in threshing and dressing, particularly in separat¬ ing the awns from the grain, for which an apparatus called a hummellmg-vnuchine is sometimes added to the threshing-mill. 4. Oats. This hardy grain is sown, with little preparation, on al¬ most every kind of soil, and too often follows culmiferous crops, as well as pulse, herbage, and bulbous-rooted plants. Where a correct course of alternate white and green crops prevails, oats usually succeed clover; and it is almost al¬ ways the first crop on land that has been several years in grass. As it prospers best on a soil not too finely pulve¬ rized, it is commonly sown on one earth. , There are numerous varieties of this species, which are distinguished by colour, form, and the period of ripening, and by the names of the countries, such as the Polan and the Dutch, from whence they are understood to have been brought, or of the places where they were origma ) cultivated. The chief of these are the common white va¬ riety, so well known as to need no description; the re , and what is called the potato-oat. For land in good cu tivation, the two latter are probably the best,—the re Ctifi' AGRICULTURE. A?r il- for uplands exposed to high winds,—and the potato va¬ tu riety in lower situations. Both of these are early, and V-z-v^yield more abundantly, in grain as well as meal, than most others. The potato-oat is said to have been discovered by accident in Cumberland in 1788. {Farmers Maga¬ zine, vol. xiv. p. 167.) But it is now very extensively raised, on suitable soils, in the north of England, and throughout the lowlands of Scotland. It usually brings a higher price at Marklane than any other variety. The red oat is so called from the colour of its husk : it has a thinner and more flexible stem, and the grain is more firmly attached to it, than in any of the early varieties ; so that upon good soils, in high situations, as it is in less danger of suffering from wind, and is at the same time so much earlier than the common kinds, it is entitled to a decided preference, particularly in a late climate. It is understood to have originated in the county of Peebles, and is sometimes called the Magbiehill-oat, from the name of the estate where it was first cultivated. 283 Seasoi f Oats are sown, usually broad-cast, in the months of suwini'i March and April, seldom earlier or later ; and from four to six bushels are allowed to an acre. The produce, which varies greatly, from this grain being sown on land of every quality, may be stated generally at about five quarters per acre. They are often carried to the barn like hay, without being tied up in sheaves; but in the north they are either managed in the way already de¬ scribed for wheat, or set up in single sheaves or gaits as they are cut, and tied more tightly when ready to be car¬ ried, and then built in the stack-yard. Wherever a threshing-mill is employed, as it is necessary, in order to have the work done well, that corn should be presented to the rollers in a regular, uniform manner, the practice of mowing, and carrying it in a loose state, is highly im¬ proper; and, independently of this objection, the season often occasions much damage to corn managed in this slovenly manner, which it would have escaped in sheaves and covered shocks. stm ^le straw oats *s more va^UG as fodder than that fodder - an^ ot*ler corn croP> and it is advantageously used as a substitute for hay diming the winter months in some ot the best cultivated districts, both for farm-horses and cattle. 5. Peas and Beans. Since the introduction of clover and turnips, the culture of peas, which are almost everywhere a most precarious ciop, has been greatly diminished. Their straw or haulm is sometimes more valuable than the grain produce, which, m a wet or late season, is frequently little more than the *eed; and when the straw is not luxuriant, so much of die land is left exposed to the growth of weeds, that it is rendered unfit for carrying corn crops till cleansed by a allow or fallow crop. Drilling is but an ineffectual reme- /. r foose inconveniences, the stems falling over and co- U'rmg the ground in so irregular a manner as in a great measure to prevent either horse or hand-hoeing at the ime when it would be most beneficial. Yet a luxuriant crop of peas, by^completely covering the surface, keeping e soa ln a moist and mellow state, and preventing the orbarhWee^S’ a S00c^ PreParation for either wheat ihe culture of beans is almost confined to clays and iJ,0n k0am8 ^le be.st mana£ed districts, turnip soils lnS y no means suited to this crop.

Peas a Deans. Beans, though still sown broad-cast in several places, Agricul- and sometimes dibbled, are for the most part drilled by ture. judicious cultivators, or deposited after the plough inv-^“\^^ every furrow, or only in every second or third furrow. In Modes of the latter method, the crop rises in rows, at regular in ter-sowinS* vals of 9, 18, or 27 inches, and the hand-hoe ought inva¬ riably to be employed; but it is only where the widest inteival is adopted that the horse-hoe can be used with much effect in their subsequent culture. In the preparation of the land, much depends on the nature of the soil and the state of the weather; for as beans must be sown early in the spring, it is sometimes impossible to give it all the labour which a careful farmer would wish to bestow. It must also be regulated in some measure by the manner of sowing. But as we are de¬ cidedly of opinion that beans ought in general to be plant¬ ed with such a distance between the rows as to admit of horse-hoeing, we shall confine ourselves to this mode of culture, which we think should be generally known, making use of the latest publication on the subject, which contains an accurate account of the different operations. {General Report of Scotland, vol. i. p. 515.) In preparing ground for beans, it ought to be ploughed Prepara, with a deep furrow after harvest or early in winter; andtory cul- as two ploughings in spring are highly advantageous, theture for winter furrow may be given in the direction of the formerbeans' ridges, in which way the land is sooner dry in spring than if it had been ploughed across. The second plough¬ ing is to be given across the ridges, as early in spring as the ground is sufficiently dry ; and the third furrow either forms the drills or receives the seed, as shall be mention¬ ed immediately. Dung is often applied to the bean crop, especially if it succeeds wheat. By some, dung is spread on the stubble previous to the winter ploughing ; but this cannot always be done in a satisfactory manner, at least in the northern parts of the island, unless during frost, when it may lie long exposed to the weather before it can be turned down by the plough. The most desirable mode therefore is, to lay the manure into drills immediately before the beans are sown. There are, as already hinted, two several modes of Sowing in drilling beans. In one of these, the lands or ridges are rows- divided by the plough into ridgelets or one-bout stitches, at intervals of about 27 inches. If dung is to be applied, the seed ought first to be deposited, as it is found incon¬ venient to run the drill-machine afterwards. The dung may then be drawn out from the carts in small heaps, one row of heaps serving for three or five ridgelets ; and it is evenly spread, and equally divided among them, in a way that will be more minutely described when treating of the culture of turnips. The ridgelets are next split out or reversed, either by means of the common plough or one with two mould-boards, which covers both the seed and the manure in the most perfect manner. When beans are sown by the other method, in the bottom of a common furrow, the dung must be previously spread over the surface of the winter or spring ploughing. Three ploughs then start in succession, one immediately behind another, and a drill-barrow either follows the third plough, or is attached to it, by which the beans are sown in every third furrow, or at from 24 to 27 inches asunder, according to the breadth of the furrow-slice. Another approved way of sowing beans, when dung is applied at seed-time, is to spread the dung, and to plough it down with a strong furrow; after which shallow fur¬ rows are drawn, into which the seed is deposited by the drill-machine. Whichever of these modes of sowing is followed, the whole field must be carefully laid dry by 1 284 Agricul¬ ture. Time of sowing. Quantity of seed. Beans and peas mix¬ ed. After-cul¬ ture. Reaping. AGRICULTURE. means of channels formed by the plough, and when ne¬ cessary by the shovel; for neither then nor at any former period should water be allowed to stagnate on the land. The time of sowing beans is as early as possible alter the severity of winter is over; in the south sometimes in January, but never later than the end of March, as the ripening of the crop and its safe harvesting would other¬ wise be very precarious in this climate. The quantity of seed allowed is very different in the southern and northern parts of Britain; in the former, even when the rows are narrow, only two bushels or two bushels and a half; but in Scotland seldom less than four bushels to the English statute acre, even when sown in ridgelets 27 inches distant, and a bushel more when sown broad-cast. Both in the broad-cast and drill husbandry it is com¬ mon to mix a small quantity of peas along with beans. This mixture improves both the quantity and quality of the straw for fodder; and the peas-straw is useful for binding up the sheaves in harvest. . The bean crop is generally harrowed to destroy annual weeds; sometimes just before the plants make their ap¬ pearance, and sometimes after the beans have got their first green leaves, and are fairly above ground, \\hen so^n in rows in either of the modes already mentioned, the harrows are employed about ten or twelve days after ; and, being driven across the ridgelets, the land is laid completely level for the subsequent operations. ; After the beans have made some growth, sooner or later, according as the soil may happen to be encumbered with or free from weeds, the horse-hoe is employed in the interval between the rows, and followed by the hand-hoe for the purpose Of cutting down such weeds as the horse- hoe cannot reach : all the weeds that grow among the beans beyond the reach of either hoe should be pulled up with the hand. The same operations are repeated as often as the condition of the land in regard to cleanness The most approved mode of reaping beans is with the % j. sickle, but they are sometimes mown, and in a few in- ti stances even pulled up by the roots. They should be cut^r as near the ground as possible, for the sake of the straw, which is of considerable value as fodder, and because the best pods are often placed on the stems near the roots. They are then left for a few days to wither, and after- wards bound and set up in the shock to dry, but without any head-sheaves. Beans are built in circular or oblong stacks, often in the latter form ; and it is always proper, if the stack be large, to construct one or more funnels, to allow a free circula¬ tion of air. They may be threshed by the mill, and dress¬ ed by the winnowing-machine, like any other grain. The produce of beans, like that of other pulse crops, is Pro, ^ exceedingly precarious, and probably does not exceed and . upon an average three quarters per acre. That of peas,s™t>n. as we have observed, is still more uncertain. But the haulm of both is valuable in the feeding of live stock; and the bean crop comes in on clay soils as a preparative for wheat, thus postponing the recurrence of a naked fal¬ low. The consumption of peas and beans is chiefly in the feeding of horses and hogs; but the proportion in which the former is grown in the best courses of husband¬ ry is comparatively inconsiderable. In the neighbourhood of London and some other large towns, varieties of the pea are cultivated for supplying green peas at an early period of the season, which at that time bring a very high price; but this belongs to gardening rather than to agriculture. 6. Tares. may require. < Before the introduction of the horse-hoe, which merely stirs the soil, and .cuts up the weeds, a common small plough, drawn by one horse, was used in working between the tows, and is still necessary where root-weeds abound. This plough goes one bout, or up and down in each in¬ terval, turning the earth from the beans, and forming a ridgelet in the middle: then hand-hoes are immediately employed ; and after some time a second hand-hoeing succeeds, to destroy any fresh growth of weeds. The same plough, with an additional mould-board, finally splits open the intermediate ridgelet, and lays up the earth to the roots of the beans on each side. The benefit of lay¬ ing up the earth in this manner, however, is alleged to be counterbalanced by the trouble which it occasions in har¬ vest, when it is difficult to get the reapers to cut low enough, and may be properly dispensed with, unless the soil be very wet and level. In an early harvest, and when the straw is not immo¬ derately rank, the bean crop becomes ripe in good time, and is easily prepared for the stack-yard. But in moist warm seasons the grain hardly ever ripens effectually, and it is exceedingly difficult to get the straw into a proper condition for the stack. In such cases it has been found of advantage to switch off the succulent tops with an old scythe blade set in a wooden handle, with which one man Can easily top-dress two acres a day. This operation, it is said, will occasion the crop to be ready for reaping a fort¬ night earlier, and also perhaps a week sooner ready for the stack-yard after being reaped. In order to have the land prepared for a wheat crop, beans are sometimes re¬ moved from the ground, and set up to dry in another field. The tare, though cultivated for its stems and leaves Ta rather than for its fruit or seeds, is so similar to the pea in its habits and mode of culture, that it seems proper to mention it in this place. The common tare is distinguished into two sorts, theta winter and spring tare. It is the opinion of an eminent botanist that they are the same plant (Walkers Hebrides, vol. i. p. 228); but though this may have been true of the tare in its natural state, there is reason to believe that a material difference now exists, superinduced per¬ haps by cultivation. (Annals oj Agriculture, vol. ii.) The winter tare, by the experiments detailed in the work just referred to, escaped injury from frosts which destroy¬ ed the spring variety. The difference in the colour and size of the seeds is, however, so inconsiderable as to be scarcely distinguished; but “ the winter tare vegetates with a seed leaf of a fresh green colour, whereas the spring tare comes up with a grassy spear of a brown dusky hue.” (Dickson’s Practical Agriculture, vol. ii. p. 889.) The winter variety is sown in September and October, S< and the first sowing in spring ought to be as early as the-0 season will permit. If they are to be cut green for sol ¬ ing throughout the summer and autumn, which is the most advantageous method of consuming them, successive sow¬ ings should follow till the end of May. The quantity o seed to an acre is from 2^ to 3^ bushels, accoi’ding to the time of sowing, and as they are to be consumed green or left to stand for a crop. M Tares are in some places eaten on the ground by dx- J ferent kinds of live stock, particularly by sheep; and as| the winter-sown variety comes very early in spring, the value of this rich food is then very considerable. The waste, however, in this way, even though the sheep e confined in hurdles, must be great; and still greater when consumed by horses or cattle. But if the plants be cu green, and given to live stock either on the held or in t fold-yards, there is, perhaps, no green crop of greater AGRIGULTURE. 285 Amul- value, nor any better calculated to give a succession of ui’- herbage from May to November. The winter-sown tare, in a favourable climate, is ready for cutting before clover; the first spring crop comes in after the clover must be all consumed or made into hay; and the successive spring sowings give a produce more nourishing for the larger animals than the aftermath of clover, and may afford green food at least a month longer. A little rye sown with winter tares, and a few oats with the spring sort, not only serve to support the weak creep¬ ing stems of the tares, but add to the bulk of the crop by growing up through the interstices. There is little difference in the culture of tares and of peas; they are often sown broad-cast, but sometimes in rows, with intervals to admit of hand-hoeing. The land ought to be rolled as a preparation for mowing; and they should always be cut with the scythe rather than with a sickle, which, by tearing up a number of the plants by the roots, renders the second growth of little or no value. When cut with the scythe, even an early spring-sown crop sometimes yields a tolerable after-crop'. In those districts where winter-sown tares are found to succeed, which is not the case in the north, the ground may be cleared in time for being sown with turnips, or dressed like a fallow for wheat to be sown in autumn. 7. Potatoes. Cult;:. Vari es. The varieties of this root are so numerous, that it would be hardly possible to give the names of them all. They differ not only in quality, being more or less farinaceous, but in the appearance of their leaves, haulm, and flowers, and in their time of ripening, as well as in the colour of the roots. Among those most commonly grown in the fields, the latter is the most obvious distinction. They are either of a white or of a purple colour approaching to black; the former being in most repute during the early months of winter, and the latter in the spring and sum¬ mer months. The kind most generally cultivated round London is the early champion, which is very hardy, pro¬ lific, and farinaceous. The yam or Surinam potato, the oxnoble, and the late champion, are grown exclusively for live stock. New varieties may be easily obtained from the seed contained in the apple. The earlier varieties, indeed,1 do not usually carry any flower; but by removing the earth from the roots, and the small potatoes themselves as they began to form, Mr Knight, the president of the Horticultural Society, succeeded in forcing the plant into blossom, and thus obtained seeds from the early as well as the common kinds. Hop i. The potato is planted in almost every description of soil, but thrives best in one that is somewhat loose and porous. In many parts of-Ireland it is the practice to plant them upon what are called lazy-beds, the sets being placed upon the surface and covered with earth taken out of a trench formed around them. tllin | the ^n<^er the best management, the land is prepared for toil. the potato much in the same manner as for the turnip, t is of much importance to free it as completely as possi- e from weed-roots, which cannot be so well extirpated a terwards, as in the culture of turnips and other drilled crops, both because .the horse-hoe must be excluded alto- get ler at a time when vegetation is still vigorous, and be¬ cause at no period of their growth is it safe to work so near the plants, especially after they have made some progress in growth. It is the earlier time of planting and P finishing the after-culture that renders potatoes a very i‘K merent substitute for fallow, and, in this respect, in no cgree comparable to turnips. For this reason, as well as on account of the great quantity of manure required, their small value at a distance from large towns, and the great Agricul- expense of transporting so bulky a commodity, the culture ture. of potatoes is by no means extensive in the best-managed districts. Unless in the immediate vicinity of such towns, or in very populous manufacturing counties, potatoes do not constitute a regular rotation crop, though they are raised almost everywhere to the extent required for the consumption of the farmer and his servants, and in some cases for occasionally feeding horses and cattle, particu¬ larly late in spring. The first ploughing is given soon after harvest, and a Planfiiw second, and commonly a third, early in spring. The land and cul- is then laid up into ridgelets from -37 to 30 inches broad,ture- as for turnips, and manured in the same manner. The usual season of planting potatoes in the fields is April, but it frequently continues till the middle of May. A week or two before the planting begins, the roots are cut into pieces or sets, each having at least one eye ; what is call¬ ed the nose-end of the root being the most valuable for this purpose. Under the drill system the sets are placed in the bottom of the furrow, between the ridgelets, at from four to eight inches distance, and the ridgelets then re¬ versed to cover them. But in some places they are still planted after the plough, commonly in every third furrow; by which means they rise in rows, at much the same dis¬ tance as in the former case, and admit of nearly the same after-culture. In either case the land remains untouched till the tops of the plants begin to rise, above the surface, when it is usual to harrow slightly across the ridges; and afterwards the horse-hoe or small hoeing-plough and the hand-hoe are repeatedly employed in the' intervals and between the plants, as long.as the progress of the crop will permit, or the state of the soil may require. The earth is then gathered once or oftener, from the middle of the intervals towards the roots of the plants, after which any weeds that may be left must be drawn out by hand; for when the radicles have extended far in search of food, and the young, roots begimto form, neither the horse nor hand-hoe can be admitted without injury. , Potatoes are usually taken up with the common plough, Gathering but sometimes with three-pronged forks : the plough goes the crop, twice along each ridgelet, in such a manner as not mate¬ rially to injure any of the roots with its share or coulter, and the potatoes are gathered by women and children placed along the line at proper distances. When the land is somewhat moist, or of a tenacious quality, the fur¬ row-slice does not give out the roots freely, and a harrow, which follows the plough, is commonly employed to break it and. separate them from the mould. Various contri¬ vances have been resorted to for this purpose: a circu¬ lar harrow or brake to be attached to the plough (see Plate VII.) has been found to answer the purpose well, and to effect a considerable saving of labour. Various suggestions have been offered for the purpose Improve- of improving the cultivation of this root. Instead of cut- ments sug- ting the roots to be planted into sets, some have recom-oeste The drill culture of turnips was first firmly established in Scotland by the practice of Mr William Dawson, a farmer at Frogden, in the county of Roxburgh, soon after his entry to that farm in 1759. Turnips had .been sown indeed on narrow ridges, according to the practice of Tull, many years before that period; but chiefly by proprietors} Drill cul¬ ture of Scotland. upon a very small scale; and the several operations were A| u[ neither so correct, so uniform, nor so much simplified as >. to induce general imitation. The first person who ever^ lVJ formed turnip ridges in Scotland with a two-horse plough without a driver was instructed by Mr Dawson, and died only a few years ago. In the drill culture of turnips, the land is ploughed with Pk L a deep furrow soon after harvest, usually in the direction tioi of the former ridges, though, if the soil be dry, it is ofsoil little consequence in what direction. As soon as the spring seed-time is over, a second ploughing is given across the former, and the harrows, and, if necessary, the rollers, are then set to work to clean and pulverize the soil. All the weed-roots that are brought to the surface are carefully gathered into heaps, and either burnt on the ground, or carried off to form a compost, usually with lime. The land is then generally ploughed a third time, again harrowed well, sometimes also rolled, and the weed- roots picked out as before. Unless land is in a much worse state, in regard to cleanness and pulverization, than it usually is after turnips have been for some time a rotation crop, no more ploughings are necessary. It is next laid up in ridgelets from 27 to 30 inches wide, either with the common swing-plough, or one with two mould-boards, which forms two sides of a ridgelet at once. Well-rotted M dung, at the rate of 12 or 15 tons per acre, is then carried to the field, and dropt from the cart in the middle one of three intervals, in such a quantity as may serve for that and the interval on each side of it. The dung is then di¬ vided equally among the three by a person who goes be¬ fore the spreaders, one of whom for each interval spreads it with a small three-pronged fork along the bottom. The plough immediately follows, and, reversing the ridgelets, forms new ones over the dung; and the drill-barrow, com¬ monly one that sows two drills at once, drawn by one horse, deposits the seed as fast as the new drills are form- So s’, ed. This drill machine is usually furnished with two small rollers ; one that goes before the sowing apparatus, and levels the pointed tops of the ridgelets, and another that follows for the purpose of compressing the soil and covering the seed. From the time the dung is carted to the ground, until the seed is deposited, the several opera¬ tions should go on simultaneously : the dung is never al¬ lowed to lie uncovered to be dried by the sun and the wind; and the new ridgelets are sown as soon as formed, that the seed may find moisture to accelerate its vege¬ tation. The time of sowing the several varieties is somewhat Ti different; the Swedish should be put in the earliest, and80 ?' then the yellow,—both of them in the month of May. But as these kinds are much less extensively cultivated than the globe, the month of June is the principal seed¬ time ; and after the first week of July a full crop is not to be expected in the northern parts of the island. The quantity of seed most commonly allowed is two pounds to the acre, which, though much more than sufficient to stock the ground with plants, is thought to be necessary for in¬ suring a regular crop on most soils. The supernumerary plants are easily taken out with the hoe; but if any parts are missed, they can be filled up only by inserting a few Swedish plants: the other varieties seldom succeed after transplantation. As soon as the plants have put forth the rough leaf, orf sooner if annual weeds have got the start of them, aj* horse-hoe is run between the ridgelets, which cuts up the weeds on each side, almost close to the rows of the turnip plants, clearing out the bottom of the interval at the same time. The hand-hoers are always set to work as soon after as possible, and the plants are left about nine inches AGRICULTURE. 287 • i. distant—the Swedish kind somewhat closer. If the ground Aw " haVbeen well prepared, and the plants not allowed to get large, three experienced hoers go over an acre a day. A few days after this a small swing-plough, drawn by one horse, enters the interval between the rows, and, taking a furrow-slice off each side, forms a smaller ridgelet in the middle. If the annuals still rise in great abundance, the horse-hoe may be employed again, otherwise the next operation is to go over them a second time with the hand- lioe when the intermediate ridgelet is levelled. Some¬ times a third hoeing must be given ; but that is done very expeditiously. When no more manual labour is required, a small plough with two mould-boards is employed to lay up the earth to the sides of the plants, leaving the ridge- lets of the same form as when sown, which finishes the process. Large fields, dressed in this manner through¬ out their whole extent, are left as clean and as pleasant to the eye as the best cultivated garden. The horse and hand-hoeing in ordinary cases may cost about fifteen shil- Weic ‘ of 6roi>.: Const p. tiim. i lings per acre. Where the soil is perfectly dry, and has been well pre¬ pared, the small plough has of late been laid aside by many farmers, and the space between the rows is kept clean by the horse and hand-hoe alone ; but if the soil be either wet from springs, or so flat as not easily to part with surface water, it is still considered proper to earth up the roots as the concluding part of the process; and it is always useful to plough between the ridges when couchgrass and other weeds have not been completely picked out before the land was sown. The gathering of the weeds, the spreading of the dung, and the hand-hoeing, are almost always performed by wo¬ men and boys and girls. A good crop of white globe turnips weighs from 25 to 30 tons per acre, the yellow and Swedish commonly a few tons less. Of late there have been instances of much heavier crops; and in Ayrshire it would appear that above 60 tons have been raised on an English acre, the leaves not included. (Farmers Magazine, vol. xv. and xvi.) But such an extraordinary produce must have been obtained by the application of more manure than can be provided, without injustice to other crops, from the home resources of a farm ; and where turnips form a re¬ gular crop in the rotation, no such produce is to be ex¬ pected under any mode of culture. Turnips are consumed either on the spot where they grow, on grass fields, in fold-yards, or in feeding-houses ; the far greater part, wherever they are extensively culti¬ vated, hy sheep. The price per acre when sold depends not only upon the weight of the crop, but also on the mode of its consumption. When eaten by sheep in the place of their growth, tur¬ nips are lotted off, by means of hurdles or nets, that they may be regularly consumed. When the first allowance is nearly eaten up, the bottoms or shells are picked out of the ground by means of a two-pronged blunt hook adapted to the purpose; and then another portion of the field is taken in, by shifting the hurdles or nets ; and so on regularly until the whole are finished ; the cleared part of tlie field being usually left accessible as a drier bed for the sheep, and that they may pick up the shells that re¬ mained when a new portion of the field was taken in. Ihe turnips required for other modes of consumption are usually drawn out at regular intervals before the sheep are put upon the field; unless the soil be so poor as to need all the benefit of their dung and treading, in winch case the whole are consumed where they grow; or so rich as to endanger the succeeding crops, by eating part of the turnips on the ground. In the latter very rare instance, the whole crop is carried to be consumed Agricul- elsewhere, as must always be done if the soil be naturally ture. too wet for sheep feeding. ^ In wet weather, when sheep ought not to be allowed to lie on the turnip field, it becomes necessary to carry die turnips to a grass field; and store sheep, not requiring to be so highly fed, frequently eat their turnips on such fields, as well as rearing cattle, and sometimes milch cows. A grass field contiguous to the turnip one is always very desirable, that the sheep, confined on other sides by hurdles or nets, may always find a dry place to lie on. In the distribution of turnips among young cattle, and sheep in their first year, towards spring, when the loosen¬ ing and shedding of their teeth render them unable to break the hard roots, it is usual to cut or slice the turnip, either by means of a spade or chopping-knife, or by an implement constructed for the purpose, called a turnip- slicer, formerly mentioned; or they are crushed by means of a heavy wooden mallet. During severe frosts, turnips become so hard that no animal is able to bite them. The best remedy in this case is, to lay them for some time in running water, which effectually thaws them; or, in close feeding-houses, the turnips intended for next day’s use may be stored up over night in one end of the building, and the warmth of the animals will thaw them sufficiently before morn¬ ing. But in those months when frosts are usually most severe, it is advisable to have always a few days’ con¬ sumption in the turnip-barn, formerly mentioned. When a severe frost continues lung, or if the ground be covered deep with snow, potatoes ought to be employed as a sub¬ stitute. The advantages of eating turnips on the place of their growth by sheep, both in manuring and consolidating the ground, are sufficiently well known to every farmer. One great defect of the inferior sort of turnip soils is the want of tenacity; and it is found that valuable crops of wheat may be obtained upon very light, porous soils, after turnips so consumed. The value or price by the acre is so various, from dif-Value, ferences in soil and seasons, and fluctuates so much ac¬ cording to the degree of abundance and demand, that nothing can be decisively stated on this subject. It like¬ wise varies according to the modes of application, as above noticed. A farmer who has turnips to sell will de¬ mand more money per acre, if they are to be drawn and consumed by the purchaser in the fold-yard, or on the pastures of the farm, than if eaten by sheep where they grow; and will require a much higher price if they are to be carried off the farm. Indeed, hardly any price will compensate for such abstraction of manure, and con¬ sequent loss of future fertility, unless where manure can be readily purchased to supply the defalcation; and that can only be done by those who are situated near towns and large villages, where a few turnips may be sold in that way for the cows of the inhabitants. Eight guineas an acre is considered a good price, in seasons of uncom¬ mon demand, for a full crop; five guineas in ordinary years; and down to thirty and forty shillings for inferior crops. Upon an average of years, five guineas may be reckoned a fair price for a good crop, eaten by sheep where they grow. Near large towns, where turnips are in demand by cowfeeders, they will sell in ordinary years for double, and when in extraordinary demand, for three or even four times these prices; but in these cases they are always removed from the farm, and consequently the manure which they produce is lost to the soil. _ * It is not uncommon to let turnips at an agreed price, Price per or board, for each sheep or beast weekly. This varies, week. 288 AGRICULTURE. Agricul- according to age and size and the state of the demand, ture. from fourpence or less to eightpence or more for each sheep weekly, and from two shillings to five for each beast. An acre of good turnips, say 30 tons, with straw, will fatten an ox of 60 stone, or 10 Leicester sheep. Supposing the turnips worth six guineas, this may bring the weekly keep of the ox to 6s. 3^d. and of the sheep to about 7^d. a week. In this way of letting, however, dis¬ putes may arise, as the taker may not be careful to have them eaten up clean. The person who lets the turnips has to maintain a herd for the taker; and when let for cattle, and conse¬ quently to be carried off, the taker finds a man and horse, and the letter maintains both. The taker has to provide hurdles or nets for fencing" the allotments to sheep, but the letter must fence his own hedges if necessary. The period at which the taker is to consume the whole is usually fixed in the agreement, that the letter may be enabled to plough and sow his land-in proper season. Storing. Common turnips are seldom stored in any great quan¬ tity, though sometimes a portion is drawn and formed into heaps like potato camps, and lightly covered with straw, or preserved for some time under a shed. On these occasions the shaws or leaves and the tap-roots must be cut off and removed before storing up, to prevent heating and rotting. The heaps must not be covered with earth like potatoes, for in this case their complete destruction is inevitable. This root contains too much water to.be preserved for any length of time in a fresh \ and palatable state after being removed from the ground; and though the loss in seasons unusually severe, particu¬ larly in the white globe variety, is commonly very great, it is probable that a regular system of storing the whole, or the greater part of the crop every season, would upon an average of years be attended with still greater loss; besides, the labour and expense, where turnips are culti- Placing. vated extensively, would be intolerable. Yet it has be¬ come a practice in some parts, particularly in Norfolk, to preserve a portion of the turnip crop through the winter, by what is called placing. They are removed from the field where they grow, and the tap-roots being taken off', the bulbs, with the haulm on, are placed close together in the position in which they grew, upon some dry, shel¬ tered spot near the farm-houses, where they are ready for use as wanted; and in this way, with little or no arti¬ ficial shelter, they are found to keep in a fresh state longer than if they had been left in the field. Diseases. Besides the damage sustained by a turnip crop from beetles and other insects, a very destructive disease, for¬ merly confined to particular districts, has lately begun to extend itself in an alarming manner; and there is reason to fear, if some means of prevention be not soon disco¬ vered, that it may almost put an end to the cultivation of this root, in some situations where it is of essential im¬ portance, both with a view to the produce of grain and Fingers to the rearing and fattening of live stock. In Holderness and toes, it is known by the quaint name of fingers and toes, from the shapes into which the disease distorts either the bulb or tap-root, or frequently both. An ingenious paper on this subject was read to the Holderness Agricultural So¬ ciety in 1811, by Mr William Spence, their president, from which we shall abstract some account of this hitherto local disease. In some plants the bulb itself is split into several fin¬ ger-diverging lobes. More frequently the bulb is, exter¬ nally, tolerably perfect, and the tap-root is the part prin- cipally diseased, being either wholly metamorphosed into a sort of mis-shapen secondary bulb, often larger than the real bulb, and closely attached to it, or having excres- icul. irs. cences of various shapes, frequently not unlike human toes (whence the name of the disease), either springina immediately from its sides or from the fibrous rootsffiaUA issue from it. In this last case each fibre often swells into several knobs, so as distantly to resemble the wire and accompanying tubers of a potato; and not seldom one turnip will exhibit a combination of all these different forms of the disease. These distortions manifest them¬ selves at a very early stage of the turnip’s growth; and plants scarcely in the rough leaf will exhibit excrescences which differ in nothing else than size from those of the full-grown root. The leaves discover no unusual appearance, except that in hot weather they become flaccid and droop; from which symptom the presence of the disease may be sur¬ mised without examining the roots. These continue to grow for some months, but without attaining any consid¬ erable size, the excrescences enlarging at the same time. If divided at this period with a knife, both the bulb and the excrescences are found to be perfectly solid, and in¬ ternally to differ little in appearance from a healthy root, except that they are of a more mealy and less compact consistence, and are interspersed with more numerous and larger sap-vessels. The taste, too, is more acrid ; and on this account sheep neglect the diseased plants. Towards the approach of autumn, the roots, in proportion as they are more or less diseased, become gangrenous and rot, and are either broken (as frequently happens) by high winds, or gradually dissolved by the rain. Some which have been partially diseased survive the winter; but of the rest at this period, no other vestige remains than the va¬ cant patches which they occupied at their first appear, ance. This disease, according to Mr Spence, is not owing to the seed, nor to the time of sowing, nor to any quality oi the soil, either original, or induced by any particular mode of cropping or of tillage ; and he adds, “ that the most attentive and unbiassed consideration of the facts has led him to infer that the disease, though not produced by any insect that has yet been discovered, is yet caused by some unobserved species, which, either biting the turnip in the earliest stage of its growth, or insinuating its egg into it, infuses at the same time into the wound a liquid, which communicates to the sap-vessels a morbid action, causing them to form the excrescences in question.” With regard to the prevention of this disease, marl has been recommended by Sir Joseph Banks and others; and where marl cannot be procured, it has been thought that an addition of mould of any kind that has not borne tur¬ nips will be advantageous ; such as a dressing taken from banks, headlands, ditches, &c. and mixed up with a good dose of lime. But lime alone has been tried in vain; and no great dependence can be placed upon fresh mould, as this disease has been known to prevail upon lands that had scarcely ever before borne a crop of turnips. {Farmers Magazine, vol. xiii.) 9. Mangold Wurzel. The mangold wurzel, or field-beet, is cultivated in much J the same manner as turnip, and used in the same way in"1 the feeding of live stock. It has been long grown in Ger¬ many, Switzerland, and other parts of the Continent, but has been but recently introduced into Britain, and is still cultivated here only upon a small scale. Very heavy crops have been raised upon clay; a circumstance which is alleged to be in favour of introducing it into the gene¬ ral rotation ; but the same thing is true of turnip, the dif¬ ficulty consisting not in the productive power of such a soil, but in its preparation and the carrying away of the Car;:s.

We shall give the substance of this communi¬ cation in his own words. “ I usually sow seed of my own growth, from eight to ten pounds per acre : if purchased, the price is in general from one shilling to one shilling and sixpence per pound. By sowing seed of my own growing, I am enabled to speak both to the nature of its stock, and likewise its quality in regard to newness. The latter circumstance is of parti- the amount of what I withheld in the short winter days. The men who tend the horses slice some of the carrots in the cut chaff or hay, and barn-door refuse; the rest of the carrots they give whole to the horses at night, with a small quantity of hay in their racks: and with this food my horses generally enjoy uninterrupted health.

For the former, perhaps, it would be as well to wash the roots when they are very wet and dirty, though I by no means think wash¬ ing generally necessary. The carrots keep best in the ground, nor can the severest frosts do them any material injury. The first week in March it is necessary to have the remaining part of the crop taken up, and the land cleared for barley. The carrots can either be laid in a heap with a small quantity of straw covered over them, or they may be laid into some empty outhouse or barn in heaps of many hundred bushels, provided they are put together dry. This latter circumstance it is indispensably necessary to attend to ; for, if laid together in large heaps when wet, they will certainly sustain much injury. Such as I want to keep for the use of my horses until the months of May and June, in drawing over the heaps (which is necessary to be done the latter end of April, when the carrots begin to sprout at the crown very fast) I throw aside the healthy and most perfect roots, and have their crowns cut completely off and laid by them¬ selves. By this means carrots may be kept the month of June out in a high state of perfection.” (Communica¬ tions to the Board of Agriculture, vol. vii. p. 72.) Mr Burrows next proceeds to state the expense of his crops for four years successively, in which he cultivated forty-nine acres in all; the average of the first three years being L.10. 13s. 2±d. and the expense of the last year, when he had twenty-five acres, L.8. 8s. 4d. per acre. In these sums, rent, interest of capital, and all other charges are included. He then details at some length the appli¬ cation of the crops, averaging upwards of 800 bushels per acre, to the feeding of cart-horses, hogs, and cattle—both milch cows and fattening bullocks,—from which there ap¬ pears to result a clear profit on the first three crops of no less than L.27. 18s. 3|d. per acre. The fourth crop of twenty-five acres was sold to the tenant who succeeded him in his farm at twenty guineas per acre, the price fixed by neutral men, leaving him a profit of L.12. 11s. 8d. per acre. Mr Burrows was so well convinced of the great advantages of this management, that he began with six¬ teen acres of carrots on his new farm ; and we are told, that the cultivation of this root is becoming more exten¬ sive, in consequence of his successful practice. Carrots in many instances are sown by hand in rows, at narrow intervals for hand-hoeing, the seeds not being easily deposited in a regular manner by the use of the drill-machine. The hand-hoeing is certainly performed more correctly, and with much less labour, when the plants are cultivated in rows.. 11. Parsnip. The parsnip has a root like the carrot; and the soil, preparation, and manure, as well as the after-culture, are nearly the same for both. The quantity of seed when sown in drills is from 4 to 5 lbs. per acre, but in broad¬ cast 6 or 8 lbs. About the middle of February is the usual sowing season, but sometimes September; and the breadth of the drills when sown in this way is 15 or 18 inches. In the island of Jersey, where it is most exten¬ sively cultivated, beans are commonly grown along with it, the beans being first dibbled in, and the parsnip seed afterwards sown, broad-cast. For fattening cattle it is considered equal, if not superior to the carrot, and gives an exquisite flavour and a juicy quality to the meat. About 30 lbs. of the root is the usual allowance to an ox at each meal, with a little hay between. When milch cows are fed with this root and hay in winter, the colour A u and quality of the butter are said to be equal to what is produced by the best pastures. Yet after all, both carrot^ and parsnip require so much labour, and are such uncer¬ tain crops in most parts of Britain, that they cannot be said to enter into the general rotation. 12. Rape. Rape is now grown to a considerable extent in somelta districts, not only for the sake of the oil expressed from its seed, but also for feeding sheep on land not well adapt¬ ed to turnips. It is cultivated on a variety of soils, as a first crop after paring and burning, and when old grass lands are brought into tillage; and it often yields a very valuable crop. Upon lands kept under the plough it comes into the rotation as a green crop; and the prepa¬ ration and after-culture are the same as for turnips; and it is sown much about the same time, or a little later, but may also be transplanted from a seed-bed so late as Sep¬ tember or October. A variety of this plant is largely cultivated in Flanders, chiefly for the sake of the oil ob¬ tained from its seed. The husks, in the form of cake or dust, after the oil is expressed, are a well known manure, which we shall have occasion to notice under the proper head. We shall give some remarks by the late Mr Culley of North¬ umberland, founded on his own excellent practice, in which rape was substituted for fallow on a poor clayey soil. “ Rape may be sown from the 24th of May to the 8th Ti of June, but comes to the greatest growth if sown in May.80'' If sown earlier it is apt to run to seed. From two to three pounds of seed is required per acre, sown by a common turnip-seed drill. But as rape-seed is so much larger than turnip-seed, the drill should be wider. When hoed, the rape should be set out at the same distance as turnip plants. The drills should be from 26 to 28 or 30 inches, according to the quantity of dung given. As many plough- ings, harrowings, and rollings, &c. should be given, as may be necessary to make that kind of poor soil as fine as pos¬ sible, and cleared of twitch, &c.; the produce will be from twenty-five to even fifty tons per acre, or upwards. But it is not so much the value of the green crop (although the better the green crop, the better will the wheat be), as the great certainty of a valuable crop of wheat, that merits attention. The sheep are put on from the begin¬ ning to the middle of August: they must have the rape consumed by the middle, or at latest by the end of Sep¬ tember, so that the wheat may be got sown on such poor damp soils, before the autumnal rains take place. The number of sheep must depend upon the goodness or bad¬ ness of the crop. But as many sheep must be employed as to eat the rape by the middle of September, or end of that month at the latest, for the reasons formerly given. The Burwell red wheat (so called from a village in Cam¬ bridgeshire) is always preferred. Poor clays will not allow deep ploughing; consequently that operation must be governed by the depth of the soil. The land must be made as clean as any naked fallow. There is scarcely an instance known of a crop of wheat, sown after rape and eat off with sheep, being mildewed ; and the grain is ge¬ nerally well perfected. Mr Culley has known a crop of wheat after rape, upon a poor moorish thin clay soil, worth much more than the fee simple of the land that produced it. He has frequently known land, both after rape and after naked fallow, in the same field; and invariably the rape wheat was better in every respect than that after naked fallow.” (Husbandry of Scotland, vol. ii. appendix, p. 45.) 13. Cabbages. The culture of cabbage in the fields is not carried onC AGRICULTURE. ,ul. upon a great scale, though very profitable crops have been t e- raised in particular situations. The variety cultivated for VAOcattle is the large field cabbage, known by several names. It prefers a strong loam, which is to be prepared in much the same manner as for potatoes or turnips, the plants being dibbled along the top of each ridgelet any time from March to June, though the earliest crops are usually the best. Plants to be used in March must be got from seed sown in the month of August preceding; but those planted out in May or June may be raised from a sowing in February or March. The after-culture consists in horse and hand hoeing and weeding, the produce being from 35 to 40 tons the acre, which is commonly used in the feed¬ ing of milch cows, but sometimes also in fattening sheep and oxen. They are excellent food for ewes that have newly dropt their lambs, as they produce abundance of milk. 14. Clovers. dovs. Clovers enter largely into the succession of crops on all soils, and in every productive course of management. Before they were introduced into cultivation, when land was exhausted by grain crops, it was necessary to leave it in a state of comparative sterility for several years before it was either valuable as pasture, or again fit for carrying corn. But at present clovers are not only indispensable in the cultivation of white and green crops alternately upon very rich soils, but are the foundation of convertible husbandry on land that is not so rich as to permit of con¬ stant aration, and which therefore requires two or more years’ pasturage at certain intervals. As the succession of crops forms the subject of the following section, in which we shall have occasion to notice the great value of clover as a crop in the alternate and convertible systems of hus¬ bandry, we shall here consider it without any particular reference to its general utility in that view. Red clover, or, as it is sometimes called, broad clover, is the kind most generally cultivated on land that carries white and green crops alternately, as it yields a larger produce for one crop than any of the other sorts. White and yellow clover are seldom sown with it, unless when several years’ pasturage is intended. As ryegrass is almost invariably sown with clover, it will be necessary to notice it also in this place. Sow ,vith Clover and ryegrass are sown broad-cast along with or corr upon growing culmiferous corn crops of every kind, and are found to prosper almost equally well with spring-sown wheat, barley, and the early varieties of oats. Being most generally sown in spring, they are usually put in immediately after the soil has been pulverized by harrow¬ ing in the corn seed, and are themselves covered by one course more of the harrows ; or if the corn is drilled, they are sown immediately before or after hand-hoeing, and the land is then finished by a course of the harrows. A lighter harrow is generally employed in covering grass- seeds than that used for corn. When the land is under an autumn-sown crop of wheat or other grain, though the clovers and ryegrass are still sown in spring, the proper period must depend both upon its condition and the pro¬ gress of the crop ; and it may be often advisable to break the crust formed on the surface of tenacious soils, by using the harrow before the clovers are sown, as well as afterwards to cover them. Sometimes the roller only is employed at this time; and there are instances of clover and ryegrass succeeding when sown without either har¬ rowing or rolling. But it is commonly of advantage to the wheat crop itself to use the harrows in spring ; and the roller alone cannot be depended on, unless the season e very favourable. In some cases grass-seeds are sown 291 by themselves, either in autumn or spring, but rarely on Agricui- tillage land, the subject of the present chapter. ture. The quantity of red clover and ryegrass sown on an acre is exceedingly various, not only according as more or Q;uantlty less white or yellow clover is sown along with them, asot see< ’ when pasturage is intended ; but even when they are the only kinds sown, the quantity is varied by the quality of the soil, and the different purposes of hay, soiling, or one year’s pasture, to which the crop is to be applied. When pasture is the object, more seed ought to be allowed than is necessary when the crop is to be cut green for soiling; and for hay, less may suffice than for either of the former. Finely pulverized soils do not require so much seed as clays on which clover and ryegrass are very frequently sown among autumn or winter-sown wheat, when there is more danger of a part of it perishing from being imper¬ fectly covered. In general, eight or ten pounds may be taken as the minimum quantity, though there have been instances of good crops from less; and from that to 14 lbs. or more per English statute acre. Ryegrass, com¬ monly at the rate of a bushel per acre, but in many cases only half or two-thirds of a bushel, is mixed with this weight of clover, and both are sown at the same time. The ryegrass may be either of the perennial or annual variety, as it is understood that the herbage is to be con¬ tinued for only one year; and the annual is sometimes sown in preference, as producing a bulkier crop than the perennial. In the selection of clover and ryegrass seeds, particu¬ lar attention should be paid to their quality and cleanness. The purple colour of the clover seed denotes that it has been ripe and well saved, and the seeds of weeds may be detected in it by narrow inspection if there be any; but various noxious weeds are frequently mixed up with the seeds of the ryegrass, which it is difficult either to dis¬ cover or to separate from them. Between the seeds of the annual and perennial ryegrass the difference is hardly Annual discernible ; and therefore, unless it is of his own growth, ryegrass, the cultivator must depend in a great measure on the character of the person from whom he purchases it. Red clover from Holland or France has been found to die out in the season immediately after it has been cut or pas¬ tured; while the English seed produces plants which stand over the second, many of them the third year (Ge¬ neral Report of Scotland, vol. i. p. 537), thus remaining in the latter case four summers in the ground from the time of sowing. Clover and ryegrass, as has been already hinted, are made into hay, cut green for being used in soiling, or de¬ pastured. As we shall have occasion to speak again of hay-making, we shall here only notice the principal ope¬ rations. This sort of herbage ought always to be cut as close to Hay. the ground as possible; and the soil, having been previ¬ ously cleared of any stones that might impede the scythe, and also levelled with a heavy roller, admits of mowing being performed in a very uniform and perfect manner, unless the crop be lodged or broken down by wind. Whatever part of the stems is left by the scythe is not only lost, but the after-growth is neither so vigorous nor so weighty as when the first cutting is taken as low as possible. Clover and ryegrass are commonly all mown in June, Time of though in the north sometimes not till near the end of cutting. July.° The time of mowing must, indeed, be determined by the growth of the plants; bufit is a common error to allow them to stand too long. They should in every case be cut down before the seeds are formed, that their juices may be as much as possible retained in the hay. When 292 Agricul¬ ture. Hay-mak¬ ing. AGRICULTURE. the stems become hard and sapless, by being allowed to bring their seeds towards maturity, they are of little more value as provender than an equal quantity of the finer sort of straw of corn. One of the best among the various modes of hay-mak¬ ing, at least for clover and ryegrass, may be described in a few words. As soon as the swath is thoroughly dry above, it is gently turned over (not tedded or scattered), without breaking it. Sometimes this is done by the hand, or by a small fork; and some farmers are so anxious to prevent the swath from being broken, that they will not permit the use of the rake-shaft. The grass, when turn¬ ed over in the morning of a dry day, is put into cocks in the afternoon. The mode of performing this is very simple and expeditious ; and none but women, boys, and girls, under the eye of a confidential servant, are usually employ¬ ed. If the crop is heavy, a row of cocks is placed in the middle ridge of three, and if light, of five ridges. A dis¬ tinct company of carriers and rakers is allotted to every such number of ridges; and the separate companies pro¬ ceed each on its own ground, in the same manner as in reaping grain, which occasions a degree of competition among them for dispatch, clean raking, and neat well-built cocks. The carriers gather the hay, and carry it to the ridge where the cock is to be built, by one of the most experienced hands. A raker follows the carrier, taking up and bringing to the cocks the remains of the swath. There may be in general about five people employed about each row of cocks; a carrier and raker on each side of the ridge on which the cocks are placed, and a person on the ridge, who builds them. But when the crop is not weighty, more rakers are required, as a greater space must be gone over. As the cocks are thus placed in a line, it is easy to put two or more into one afterwards; and the larger cocks may be speedily drawn together, to be put into tramp- ricks, by means of ropes thrown round their bottoms, and dragged along by a horse. It is impossible to lay down any rules for the management of hay after it is put into cocks ; one thing is, however, always attended to, not to shake out, scatter, or expose the hay oftener than is real¬ ly necessary for its preservation. Sometimes the cocks have been put up so large, that they never required to go to a tramp-rick, but were carted to the stack-yard, with¬ out ever being broken, and put up in alternate layers with old hay. But where this is attempted, there must not be much clover. The practice of mixing the new with the old hay is, however, a good one, and saves a great deal of time and labour, at the same time that the old hay is much improved by the mixture. The best managers disapprove of spreading out the swaths of clover and ryegrass, though this is often neces¬ sary with natural grasses, which are cut and harvested later in the season. The more the swath is kept unbroken, the hay is the greener and the more fragrant. Another mode of hay-making, said to have been original¬ ly practised in Lancashire, has been found to answer well in the moist atmosphere of the west of Scotland. This is called tippling or rippling ; and, if the grass be dry, the operation begins as soon as it is mown. “ In making a tipple, a person, with his right hand, rolls the swath in¬ wards, until he has a little bundle; then the same is done by the left, until both meet, and form 8 to 12 pounds, or nearly so. This bundle is then set up against the legs, or between the feet; a rope is twisted off the grass, while the bundle is supported in this manner, and tied round it, near its top ; and from the top are drawn up a few strag¬ gling stems, which are twisted, to make the tipple taper to a point, and give it as much a conical shape as possible. If the crop is strong, there is a row of tipples placed on each swath; if light, two of these are put into one row. a After standing a few hours, they become so smooth on the outside, that the heaviest rains seldom wet them through and when wet, they are soon dried again in good weather! As soon as ready, they are put into the summer-rick, or, if very dry, even into the winter-stack, but are never opened out or tedded to make them dry, as they never require it. By this method not a blade is lost, and the hay is nearly as green as a leaf dried in a book. In a moderate crop, one woman will tipple to one mower, and a woman will rake to two tipplers or two swathers. But where the crop is strong, it may require three women to keep pace with two mowers. After the hay is put up in this manner, the crop may be considered as secure, though it may continue wet weather for a considerable length of time.” ( General Heport of Scotland, vol. ii. p. 11.) Hay is commonly carried to the stack-yard, and built St either in circular or oblong stacks (the latter form being most generally approved of), and carefully thatched, as has been already observed in regard to corn. It is never ad¬ visable to allow this kind of hay to become heated in any considerable degree in the stack, though a slight exuda¬ tion, with a very gentle warmth, is usually perceptible, both in the field ricks and in the stacks, for a few days after they are built; but this is quite a different thing from that intentional heating, carried so far, in many instances, as to terminate in conflagration. The weight of hay from clover and ryegrass varies, ac-Pi cording to the soil and the season, from one to three tonspe per English acre, as it is taken from the tramp-ricks; but after being stacked and kept till spring, the weight is found to be diminished 25 or 30 per cent. Its price per ton depends entirely on situation : at a distance from towns or large villages, in ordinary seasons, the price is usually very low, and the whole of it is generally consumed on the farm that produced it. Its intrinsic value as fodder, in comparison with the straw of beans or peas, may be in the proportion of three to two; and with the finest straw of corn crops, in the proportion of two to one. Many intelligent cultivators consider ryegrass as a very o severe crop for the soil; and it is alleged that wheat does to not succeed well after the herbage with which it is inter-gr mixed in any considerable quantity. Other plants have accordingly been recommended as a substitute for rye¬ grass, and cocksfoot (Dactylis glomerata) has been tried, apparently with great success, by Mr Coke of Holkham, in Norfolk, and others. But this is a very coarse grass when allowed to rise to any height, and the use of it for hay has not yet been fully ascertained. When the hay crop is cut and removed, there is com¬ monly a vigorous after-growth, which may be either cut or pastured. As this consists almost exclusively of red clover, and is extremely succulent, it is seldom made into hay, owing to the difficulty of getting it thoroughly dried at a late period of summer, when other more urgent operations usually employ all the labourers of a farm. If it be cut for this purpose, the best method of saving it is, to mix it up with straw, which will absorb a part of its juices. It is often cut green, as a part of the soiling system; or, where a sheep stock is kept, pastured by the old ewes, or other sorts, that are to be fattened the ensuing winter on turnips. On all farms under correct management, a part of this S crop is cut green for the working horses, often for milch cows, and in some instances both for growing and fatten¬ ing cattle. This mode of consuming it is known by the name of soiling. There can be no doubt of the advantages of this practice in regard to horses and cows; but for young and for fattening beasts, a sufficient number ol ml e. ce re. !;d AGRICULTURE. 293 i pxneriments are not known to have been yet made with m anv ffreat degree of accuracy. Young animals require ✓v-'exercise in the open air, and probably will not be found to thrive so well in houses or fold-yards, during summer, as on pastures; and though in every case there is a great saving of food, the long, woody, and comparatively naked sterns of the plants, with leaves always more or less withered, are perhaps not so valuable in the production of beef on fattening stock, as a much smaller weight of herb¬ age taken in by pasturing. Milch cows, however, are so impatient of heat and insects, that this way of feeding them, at least for a part of the day, in warm weather, ought to be more generally adopted ; and the convenience of having working horses always at hand, besides that they fill their stomachs speedily, is of no less importance than economy.1 . In feeding cattle with green clover, attention must be paid to prevent swelling or having, which is very apt to take place when they are first put on this food, especially if it be wet with rain or dew ; and cattle are exposed to this danger, whether they are sent to depasture the clover, or have it cut and brought home to them ; though, if the plants be somewhat luxuriant, the danger is greater in the former case. After being accustomed to this rich food for a few days, during which it should be given rather sparingly, the danger is much diminished; but it is never safe to allow milch cows, in particular, to eat large quanti¬ ties of wet clover. Wuof We have hitherto spoken of red clover and ryegrass, ed. as cultivated for the sake of the stems and leaves, and shall now add a few words about the management requir¬ ed when the object is to save their seeds. Ryegrass seed is gathered in almost every part of Britain, but clover seed can seldom be saved in any profitable quantity in the northern parts. In Scotland, red clover is never cultivat¬ ed for seed. Ivefiss The common practice in regard to ryegrass is, to let die mixed crop of that and clover stand till the seeds of the former have attained a considerable degree of ripeness, when it is cut down and made into hay in the usual man¬ ner ; and the seeds of the ryegrass are separated by the use of the flail, commonly before the hay is put into the field-ricks. Sometimes, when but a small quantity is wanted, the hay is merely shaken well upon a cloth, when it is building in the stack-yard; or afterwards, in the stable- loft, before it is put into the horses’ racks. But in all of these methods, in order to obtain good seed, the clover must remain uncut beyond the proper season; and it is thus materially injured in quality, while the value of the ryegrass seed, in such a crop, is merely a secondary con¬ sideration. When seed is the principal object of the culture of rye¬ grass, it ought not to be mixed with clover at all, though it maybe sown along with any of the kinds of corn already mentioned; and it is treated the year after in every respect as a crop of corn; bound up in sheaves, built in stacks, threshed with the flail, and dressed by the winnowing- machine, in the same manner. The difficulty of distinguishing between the annual and perennial varieties of ryegrass has led to the practice, in some places, of cutting or pasturing the first year’s crop, and taking a crop for seed in the second year. If the growth of the ryegrass plants be close and vigorous the second year, there is reason to be satisfied that the seed is of the perennial variety; and though red clover has been sown with the ryegrass, a great part of it disappears Agricul- by that time, and forms but a’small portion of the second lure. year’s cutting. The seed of red clover is saved with more labour and Clover difficulty. As the plant does not perfect its seed early in seed, summer, it is necessary to take off the first growth, either by feeding or cutting. In the first case, it is eaten till about the end of May, frequently by ewes and lambs; and this is understood to be an advantageous practice, because the land is less exhausted, and the green food is of great value for stock in the spring months. It is not uncom¬ mon, however, to cut the first growth for a hay crop; and this should be done earlier than usual. The growth thus reserved for seed must be suffered to remain till the husks become perfectly brown, when it is cut and harvested in the usual manner, leaving it on the field till it is very dry and crisp, that the seeds may be¬ come more fully hardened : it may then be laid up dry, to be threshed out at the farmer’s convenience. Much labour and expense are necessary in separating Seeds for the seed from the capsule or seed-coat, especially when pasture, it is effected by threshing, which seldom costs less than from five to six or seven shillings per bushel. By the use of mills the work may be done much cheaper. The produce in seed may generally be from three to four or five bushels per acre when perfectly clean, weigh¬ ing from two to three hundredweights. But there is great uncertainty in the produce of clover seed, from the late¬ ness of the season at which it becomes ripe ; and the fer¬ tility of the soil is considerably impaired by such a crop. Yet the high value of the seed is a great inducement to the saving of it, in favourable situations. (Dickson’s Practical Agriculture, vol. ii. p. 863.) When it is intended to retain the land in pasture for several years, the quantity of red clover is diminished, and several kinds of more permanent herbage are added, the most common of which are, white and yellow clover, and ribwort. No general rule can be laid down as to the proper quantity of each of these kinds; in some cases red and white clover are sown in equal proportions, and in others the latter is made greatly to predominate. The yellow clover and ribwort are not often sown at the rate of more than two or three pounds per acre. It is scarcely necessary to add, that in this case the ryegrass should always be of the perennial sort. When permanent pasture is the object, a still greater variety of seeds has been recommended. But as cultiva¬ tors are by no means agreed on this point, and as the dif¬ ferent kinds and proportions which are thought best adapted to different soils have none of them the sanction of extensive experience, we shall refer the reader to the third volume of Communications to the Board of Agricul¬ ture, which is wholly occupied with essays on the best means of breaking up old grass-lands, and restoring them after a few years to permanent pasture. 15. Lucerne. This is a deep-rooting perennial plant, that sends up nu- Lucerne, merous tall clover-like shoots, which bear blue or violet-co¬ loured flowers. It is much cultivated in the south ot Du* rope, and has also been found to answer in some parts of England, though the principal seat of its culture is Kent. The Roman writers Be Be Bustica extol this plant beyond all reasonable bounds, and are very minute in their direc¬ tions about its cultivation. Lucerne requires a very deep, 1 See Communications to the Board of Agriculture, vol. vii. vol. ii. and iii. Brown’S Treatise on Rural Affairs, vol. ii.; General Report of Scotland, 294 AGRICULTURE. Agricul- friable soil, inclining to sand, with a subsoil of a similar cha- ture. racter. It is sown, either in drills or broad-cast, in March or early in April, and sometimes along with barley; the quan¬ tity of seed being from 15 to 20 pounds if sown in the latter way, and from 8 to 12 if in the former. It must always be kept free from weeds, and should be top-dressed with dung or other manure at least every five or six years. Some prefer giving it a slight dressing every spring. It is con¬ sumed in much the same way .as clover, either in a green state, or after being made into hay. In some very favour¬ able situations it admits of being cut five times in the course of the summer. It is an excellent food in its green state, both for horses and milch cows ; and if it be equal in the quantity of its produce to a full crop of red clover, and continue in a productive state for nine or ten years with only the expense of occasional top-dressings, it would appear to be entitled to a preference on all suitable soils and situations. The failure of clover on lands where it has been long or too frequently grown, a fact which seems to be generally admitted, may induce our farmers to make trials of lucerne in places where it is yet very little known ; and it may possibly in time become so in¬ ured to our climate as to answer in parts of the island where it is now thought unlikely to succeed. Though it can never come into our rotations like red clover, on lands kept under an alternate course of corn and green crops, not attaining its most productive state in a single year, yet it may be introduced upon those soils which require to be kept from the plough, and in pasture for several years, before they are restored to tillage. 16. Saintfoin. Saintfoin. This is also a deep-rooting perennial plant, suited to dry, warm, chalky soils. It is sown in February or March, at the rate of about four bushels to the acre, sometimes along with barley or other kinds of grain ; is ready for be¬ ing mown the second year, and may last from seven to ten years, though in its greatest perfection in about three years. The produce in hay is from ton to 2 tons per acre. It is mown for soiling or hay, or pastured in the same way as clover. If the crop is chiefly taken off1 by mowing, it must be occasionally top-dressed with manure or peat ashes. 17. Flax and Hemp. The soil most proper for flax is one that is deep, friable, and rather moist. It often succeeds well in lands taken up from grass, or after only one crop of corn. In Ireland it is usually sown by the small farmers after potatoes. The land must be well pulverized before the seed is sown, cleared of stones or roots, and rolled after the seed is put in. The usual time of sowing is from the middle of March to the end of April. Dutch seed is in the highest esti¬ mation, affording a greater produce than the American seed, and a finer quality than the Riga. The after-cul¬ ture consists in taking up the weeds as they rise,—a very tedious process if the land be at all foul, as it can only be done by the hand,—and in some cases in the further use of the roller. . The crop is raised by pulling up the plants by the root: immediately after, they are put into a pool to be steeped or watered; and, when taken out of the pool, spread out upon grass-land to dry and bleach. The time allowed for steeping and bleaching varies with the condition of the plant and the state of the weather, but need seldom exceed 10 or 12 days for each. But both these processes may be dispensed with by the use of Hill and undy s patent machines, by which the entire preparation may be completed in six days. The produce in seed, when that is the object, is from 6 to 8, and sometimes as Flax. high as 10 or 12 bushels per acre. The best of it is kept for sowing again, the next quality is crushed for oil, and the inferior is boiled or steamed for cattle. The cake it A self, or the residuum after the oil has been expressed from the seed, is alone a valuable article in the fattening of live stock and in the rearing of calves. The produce of flax in fibre may vary from 3 cwts. to half a ton the acre. Hemp requires a deep, black, vegetable soil, somewhat! inclined to moisture ; and the preparation and season for sowing, and the after-culture and management, are all nearly the same as for flax. . But the male plants are usually taken up four or five weeks before the female, so as to give the latter time to ripen their seeds. Flax and hemp, when allowed to ripen their seeds, are considered exhausting crops, even more so than corn; and, in most parts of Britain, are so uncertain in their produce, that their cultivation has hitherto been very li¬ mited. But a great deal of flax is raised in Ireland. 18. Hops. The hop has been long cultivated extensively in seve-E ral parts of England, and would probably answer in the south of Ireland ; but it is not adapted to the climate of Scotland. In the most favourable situations it is a most precarious crop, sometimes yielding large profits, and at others scarcely defraying the expenses of management. The soils most favourable to the growth of hops are clays and strong deep loams, with a dry, friable subsoil. “ When it is intended to make a new plantation, the Pi best method is to have cuttings from approved stock planted out the year before they are wanted in the hop- ground, as the use of plants instead of cuttings not only gains a year, but they are more certain to flourish, as many of the cuttings will not take root in a dry season, unless they are watered, which is seldom resorted to. A small piece of moist land is sufficient to raise plants for many acres, and at little expense. If the ground be in grass, some would pare and burn the surface, and take a crop of grain, which is not so advisable as paring and digging in the sods. The land is worked with a spade, and set out into ridges of 3^ yards wide, and two yards be¬ tween each, having a strip of grass (called a pillar) next every ridge, and an open drain between every two pillars, the depth of which must vary according to the soil, some being less than one foot, and others nearly four feet in depth. Three rows of plants, or, as they are termed, hills, are made upon each ridge, which should intersect each other. They are generally nearly two yards distant in the rows, so that about 1300 are the usual number of hills in a statute acre ; but as some grounds, where only two poles are set at each hill, are in narrower ridges, the number of hills is consequently greater. Small sticks are proper to tie the bines up to the first year, then small poles for a year or two, the size of which should be gra¬ dually increased. Some set two poles to every hill, which is proper for ground producing luxuriant bines; but on clay land, three poles are set in a triangular form to the hills on the two outside rows of each ridge, and only two in the middle row. Many additional poles, longer than the rest, called catch-poles, are also set to take the bines as they run beyond the lesser poles. Where the bine is weak, three heads are commonly trained up each pole; though two are better, if strong. Their course round the pole is the contrary to that of the kidney-bean. If the ground intended for a new plantation is not clean from couchgrass, a complete fallow is essential, whether it is grass or stubble ; and a crop of turnips may be taken to advantage if the land is proper for their growth, and can be made clean, as hops are planted in March. AGRICULTURE. 295 Man „ ui. « The expense of taking up hop-ground is from five to six pounds per acre, as the price of planting varies with the mode pursued; and if the drains are required to be Jeep, or the soil is particularly strong, a still greater sum will be expended; to which may be added L.25 per acre for poles, before the ground has its full quantity; and also the rent, taxes, &c. and the working for three years, be¬ fore many hops can be expected. A substantial building for an oast or kiln cannot be erected for L.100, if it has store-rooms necessary for only five acres. The following are termed the annual orders :—Digging the ground com¬ pletely over, hoeing the earth from the hills, and cutting off the stock a little above the root, which are called pickling and cutting; poling, which is carrying the poles from the stacks, and setting them down to the hills with a round implement shod with iron, and called a poy, hav¬ ing a crutch at the top, and a peg through the middle to tread upon; tying the bines round the poles with rushes, and pulling up the superfluous bines; hoeing the ground all over with a hoe of large dimensions; wheeling and laying manure upon every hill; covering the manure with the soil, which is done by scraping the ground over with a hoe, and is called hilling; and stacking, which is carrying and setting up the poles into heaps or stacks, after the crop has been taken. The annual expense of these orders varies from L.2. 15s. to L.3, 5s. per acre. “ As to the manure most proper for the hop-culture, good stable dung is much used, and is preferred to the manure made by cattle, as the latter encourages ants on strong ground. Woollen rags are the best for forcing a luxuriant bine, and, if used with judgment, are excellent for clay ground ; but they are apt to make the hops small, if too many are used. Malt culm and dove manure are excellent; and one complete dressing with lime is very serviceable for strong ground. Taki the “ When the crop is ripe, a proper number of pickers are procured, for whom are provided light wooden frames, called binges: they are clothed with hop-bagging, into which the hops are picked off the poles by women and children, having them brought by men, who take them up by cutting the bines about a foot above the ground, and drawing up the poles by an instrument called a dragon. Each binge has from four to six pickers, and a man at¬ tends to one or two binges, according to the crop ; he strips the bines from the poles as they are picked, and lays them in heaps ready for stacking ; he also carries the hops to the kilns, if near, or to a cart as they are mea¬ sured from the binge. It is necessary to have a supply of cokes in the kilns to dry the hops, which are spread on a hair-cloth which is upon an upper open floor of wood, above the fire or fires, every noon and midnight, whilst the picking continues. They are stirred repeatedly^, and, when cured, are turned off into the store-room, to be put into bags and pockets (after they have been there about a week), which is done by fixing each bag (being first le¬ gally marked with the grower’s name, &c.) in a frame, and treading the hops in. The excise-officer, who at¬ tends during the season, then weighs them, and charges ~d. per pound for the duty, when they become marketable. “ from the foregoing particulars, it will appear that t lore is scarcely any hop ground but costs yearly upwards or L.12 per acre (exclusive of the picking and duty, which may exceed L.20 per acre, or be very little) ; and there are other grounds in which upwards of L.20 per acre are annually expended; so the average may be said to be dutUt Per acre> without the picking, drying, and If a good plantation produces 10 cwt. per acre in a crop year, which are sold at L.5 per cwt., the annual ex¬ cropjn hixli Agricul¬ ture. penses being L.20, and the picking, &c. and duty L.20, the profit will be L.IO; and admitting that the same ground pays all expenses in a blight year, and supposing'' that to be every third year, the profits would be nearly L.7 per acre annually; but, as the foregoing crop cannot be expected on any ground every other year, the produce of the third year may be stated at 5 cwt. per acre, at 8 guineas per cwt., deducting the annual expenses, L.20, and the picking and duty, L.12. “ This plant, is extremely liable to disasters, from its Hops ex- first putting up in the spring, until the time of picking the posed to crop, which is in September. Snails or slugs, ants and Sreat risk fleas, are formidable enemies in the first instance. Frostsfrom Sl;a' are inimical to its growth; and the bines are frequently -°ge“d blighted, even after they have reached the top of the poles. Small green flies, and other insects, which make their appearance in the months of May and June, when the wind is about north-east, often greatly injure them; and they are subject to take damage by high winds from the south-west. The best situation for a plantation, therefore, is a southern aspect, well shaded on three sides, either by hills or planting, which is supposed to be the chief protection that can be given them.” We have taken these observations on hops from an able communication by Mr Parkinson, himself a hop-grower, given in the Far¬ mers Magazine, vol. xvi. On a suitable soil, a hop plantation may continue for fifteen years or more, but commonly begins to fall off about the tenth year. The expense of forming one has been estimated in all at from L.70 to L.100 per acre. One ob¬ jection to the cultivation of hops is, that they require a great deal of dung, which in most cases can only be pro¬ cured by abstracting it from the tillage-lands. On the other hand, it is admitted, that upon suitable soils, and under good management, they make a very profitable re¬ turn. 19. Crops occasionally cultivated. Under this head we may notice a few plants, which, Crops oc- though of some local importance, cannot be considered as casionally forming an object to agriculturists generally. cultivated. 1. The Fuller s Thistle or Teazle, the heads of which Fuller’s are used for raising the nap on woollen cloths. It is grown thistle, in Essex and the west of England. 2. Woad. This is now chiefly cultivated in Lincoln- Woad. shire. It is used in dyeing, as a basis for black and other colours. 3. Weld or Dyers Weed is cultivated in some parts of Weld. England, chiefly in Essex, and used for giving a yellow colour to cotton, &c. 4. Spurry {spergula, arvensis), which is a diminutive Spurry. annual weed, that grows on dry, sandy corn lands in most parts of Europe. In Germany and the Netherlands it is sown on corn stubbles, and fed off' with sheep; and is. said to enrich the milk of cows, and improve the quality of mutton. Some writers have recommended its cultivation in England, where it probably would not pay the expense of seed and labour. 5. Fiorin. This plant has been strongly recommended, Florin, within these few years, by the late Dr Richardson of Ire¬ land, as suitable, not for meadows or hay ground only, but also for arable land; and for this reason it is noticed here. In consequence of that gentleman’s writings, trials were made of it upon a variety of soils in different parts of Scot¬ land, particularly and upon a large scale at Dalswinton in Dumfries-shire ; and the result seems to be, that though a heavy crop of it may certainly be procured on mossy or peaty soils, yet that upon all other descriptions of land it is not by any means so valuable as the crops already in 296 AGRICULTURE. Agricul- use. It does not admit of being pastured, aifords only one ture. cutting in the year, requires to be top-dressed with ashes or other manure ; and after all, upon moderately dry soils, the produce is of very little value. We have seen a crop of it upon rather dry land, under the management pre¬ scribed by the doctor himself, which would scarcely pay the expense of cutting and carrying to the farm-yard. Still we think it deserves the notice of those wdio possess moss lands, as there can be no doubt of its having yielded a large produce under the doctor s own management, and we believe also on a similar soil at Dalswinton. It is cer¬ tainly relished by horses and other live stock. Buck 6. Buck Wheat. In this country buck wheat is chiefly wheat. cultivated for feeding poultry, pigeons, and hogs ; though it is also used in the distilleries, and occasionally the meal is made into thin cakes for bread. It will grow on almost any soil, and may produce on an average from 3 to 4 quarters the acre. The season of sowing is the last week of April, or first week of May. When allowed to stand for a crop, there is nothing worthy of particular notice in its after-culture or management; but some think it of most value when ploughed down green, as a preparation for other crops. Maize. 7. Maize or Indian Corn is now under trial in this coun¬ try by Mr William Cobbett, who is very sanguine of suc¬ cess. It has been hitherto considered as a crop quite un¬ suited to the climate of Britain. Kelp. 8. Kelp. The plants from which this substance is made can hardly be said to belong to agriculture, yet it is never¬ theless of too much importance in many parts of Scot¬ land and Ireland to be passed over without notice. It is made from different varieties of the fuci, among which the fucus vesiculosus is considered the most productive. The plants which grow on the sea-coast are cut in the sum¬ mer months, and dried and burned in a rude sort of kiln on the spot. It is of great importance to preserve them from the rain when they have been laid out to dry. The plants may be cut when two or three years old. There are immense tracts on the coast of the mainland and islands of Scotland, wdiere it is thought kelp might be produced merely by putting down stones upon the vacant spaces. During the late war, the best sorts of kelp some¬ times sold for L.20 per ton, and the land-owners derived a very considerable profit from its manufacture; but since the peace, barilla having come again into our market at a reduced price, that of kelp has fallen so low as to yield little or no profit, after defraying the necessary expenses. The principal consumption of kelp is in the manufacture of glass and soap. The barilla plant itself, it is believed, might be tried in this country, with a reasonable prospect of success. It has been introduced into France, where the produce was found to be as good in quality as that procured from Alicant. But the most important step, perhaps, would be to improve the manufacture of our own kelp ; a point to which the Highland Society of Scotland has very properly given much of its attention of late, and in whose publications a great deal of useful information will be found upon the subject. Kelp- The following account of the manufacture in the island making, of Harris, one of the western isles of Scotland, is from the 6th volume of the Prize Essays and Transactions of that Society, published in 1824. “ !• The quantity of kelp manufactured on the farm of Strond this season was 115 tons. “ 2. All the kelp was made from cut-ware of two years’ growth. “ 3. The plants used were, fucus nodosus, or lady-ware; fucus vesiculosus, or bell-ware; and fucus serratus, or black-ware. “ It may not be superfluous to remark, that all the kelp made of cut-ware is from these different plants, and that they are always mixed together, as the different varietiesv- grow on kelp-shores generally, and in the following or¬ der ;—The fucus nodosus grows on that part of the shore between high-water spring-tides and high-water neap- tides ; and mucous bell-ware, named grcepach by the ma¬ nufacturers, is interspersed with it. As these kinds of ware are but seldom covered by the sea, they are short, and only a little of them can be obtained. The fucus ve¬ siculosus, or bell-ware, grows on that part of the shore between high-water neap-tides and low-water neap-tides. From the circumstance of this ware being alternately covered by the sea and exposed to the air for nearly the same space of time, it grows stronger than any of the other varieties; is consequently more plentiful, and most productive. That part of it which grows near low-water¬ mark neap-tides is of a thinner texture, and is called floating-wrare, or gleurach. The fucus serratus, or black- ware, grows between low-water neap-tides and low-water spring-tides; this variety of ware is plentiful on such shores as are flat, and which only ebb with spring-tides. Black-ware makes good kelp, but is not so productive, from its thin texture. “ Different varieties of tangle-ware appear lower down than the black-ware at low-water spring-tides, but are not cut for kelp-making in those parts, and are only used when drifted ashore for making cast-ware kelp. “ 4. The specimens of Strond kelp now sent to the So¬ ciety were taken without any pains of selection, from about 60 tons of the kelp; each specimen sent being taken from different kelp-kilns, contain¬ ing from 2 to 21 tons of kelp each. All the kelp made on the farm was equal in quality to the spe¬ cimens sent, with the exception of about 6 tons, which were made in a bay into which there is a run of fresh water, and where the ware is only covered with salt water with spring-tides. Kelp made of such ware contains less of the alkaline salts than when it is made from that which grows on strong tide-ways. “ 5. The kelp from which the specimens were taken was sold by Messrs Macdonald and Ravenscroft, agents, Liverpool, for L.10. 5s. “ 6. The process of manufacturing this kelp is as follows, and though similar, may be found to differ in some respects from the general mode of kelp-making. Wherein I consider this difference lies I will point out, by underscoring that part of the description of the process. “ 1. The ware is cut off the rocks with a common hook, similar to that used for shearing (reaping), but stronger, and having a rougher edge. “ 2. Care is taken to land the ware on clean spreading ground; and if any sand or mud is found to stick to the ware, it is always washed before landing it. “ 3. The ware is spread out every dry day, and made into small cocks at night. When in this way it is found to be pretty dry, it is made into larger cocks, and left to heat in them for six or eight days; but if the ware is of that description which I have mentioned above as growing in bays into which there is a run of water, such ware is always left in large cocks for 15 or 20 days. “ 4. The ware being thus secured, a dry day with a good breeze of wind is watched for, in order to burn it. “ 5. The kelp-kilns are constructed of middle- ieu He. r\ AGRICULTURE. As.^L te. Sfa-- sized stones, of hard texture, and built up care¬ lessly ; the outsides of the kilns are covered with J turf; the length of each kiln is from 15 to 18 feet, breadth feet, height 2 feet. They are made on the surface of the ground, and on the firmest sward they can find. “ 6. The process of burning is as follows:— A small bundle of straw or heather is set on fire; the dryest part of the ware is placed over this, and gradually added, until the flames become ge¬ neral through the kiln; then the ware to be burnt is thrown in, little by little, till the whole is re¬ duced to ashes. If, however, it happens that the day is too calm, or that the ware is not sufficiently dry, so that the ashes cool and cake into white crusts, the manufacturer stops burning any more, until he rakes all the ashes in the kiln ; then com¬ mences burning again, and goes on in this way until he has the whole thoroughly burnt. Want of attention to this method leaves kelp of a white colour and porous texture. “ 7. The last process is the raking or working of the ashes with an iron with a wooden handle, made for the purpose, until the whole is brought into a solid semi-vitrified state. Most manufac¬ turers commence this process immediately after the last part of the ware is put into the kiln, and when a good deal of the ware is not sufficiently burnt, and of a black colour. The Strond manu¬ facturers, however, do not commence raking the ashes for at least half an hour after the last of the ware is put on, so that the whole may be tho¬ roughly burnt. Want of attention to this particu¬ lar leaves kelp of an ugly black colour. “ The raking of the ashes is simply done by working the kelp-irons through it until the whole becomes a semi-vitrified mass. Three ov four men are employed at this process; if fewer, the ashes will not be sufficiently worked, and consequently a great part of them must be mixed in the next burning. “ Finally, The kelp is broken into pieces of about 2 cwt.; these are made into conical heaps, covered with dry ware, and over that is placed a layer of turf, which secures the kelp tolerably well, if early shipped.” 9. Sea-grass {zostera marina) is a plant which abounds in the Orkney Islands, and has lately come into use for stuffing chairs, mattresses, and other sorts of furniture in which horse-hair was formerly used. When properly prepared, it is found to be elastic and durable, and is not subject to the attacks of those insects which often infest mattresses made of wool or cotton. dhe following account of this plant is taken from the Prize Essays and Transactions of the Highland Society, vol. vi. and was written in 1823. “ The zostera generally grows at such depths as to be left nearly dry by the ebbing of spring-tides. “ The leaves remain attached to the stem until the month of September, and during the autumn and begin¬ ning of winter are thrown ashore in large quantities. “ As this plant floats near the surface of the water, it 18 always driven before the wind; unlike the other marine 297 either gathered into heaps with other marine plants, and Agricul- allowed to ferment before being applied to the land, or ture. formed into compost with earth, litter, &c.; in both of which ways it is found to answer well. “ It is also used by the poorer classes of labourers or cottars as thatch for their houses, and in this way forms a good defence against the violent winds and heavy rains of their rude climate, for two years. “ Its application as a substitute for horse-hair, in stuf- A substi- fing mattresses and furniture, was unknown in these tute for islands until the attention of a few individuals was de-{lorse-hair voted to it by the offer of a premium by the Highland111 mat*' Society of Scotland, for its preservation for that purpose,tresses- and with a view to its introduction as a useful article of manufacture. “ The list of premiums offered by the society happen¬ ing to come into the hands of the writer of this brief and imperfect sketch during last autumn, he conceived he might employ some of his people profitably in collecting, washing, and drying the grass for sale. The season being unluckily too far advanced for procuring any large quan¬ tity, he prepared, by way of experiment, 1 ton 3 cwts. 14 lbs. which his agent has since sold to the manager of the Asylum for the Industrious Blind at Edinburgh, at the rate of 12s. 9d. per cwt. On this quantity, which grossed L.14. 15s. his net profit did not exceed L.8; but this partly arose from inexperience in the mode of pre¬ paring it. On a quantity amounting to nearly three tons, which he has got ready for market within these few wreeks, the expenses of washing, drying, and picking, have not amounted to more than half of the charge on the smaller quantity first noticed. The first was carefully washed twice in vessels filled with fresh water, and dried quickly, and then any sea-weed that had floated ashore with it picked out when dry. The last was carted to a fresh¬ water lake, and steeped during a week, when it was taken out, and picked by boys and young girls while spread wret upon the ground. If properly steeped, exposure to drought for one day will make it sufficiently dry for packing. When dry, care must be taken, if the weather is windy, to ga¬ ther it into heaps or cocks, otherwise it may be blown away, being then extremely light. The first quantity prepared was sent to market in large bags of sacking, of the size of wool-packages, very hard packed; yet that small quantity required 14 bags to contain it. The last has been twisted into ropes, of the thickness of a man's waist, and then compactly made up in nets formed of ropes made of bent-grass. “ The zostera is a plant of a very imperishable nature, and may be kept for any length of time in fresh or salt water, without any apparent decay. Should a sufficient demand arise for this grass, at a fair price, any quantity could be collected in the Orkney Islands that the market could require; and it would furnish a species of labour well adapted to old people past hard work, and young people not yet able for hard work. The wages generally given for such sort of work at present is 6d. per day, which is more than can be earned by plaiting straw, the staple employment of young people in the Orkney Islands.” Sect. VII. Succession of Crops. There is no branch of husbandry that requires more Succession plants of these islands, which (with the exception offucus judgment, nor any on which the profits of the farmer more0* crops. resiculosus, whose air-vessels keep it afloat) remain near t.'e Attorn, and are forced ashore, against the wind, by t ie ground-swell or reflux of the waves. ’ l*4 sea1=rass ^ used hy the inhabitants of these b anas as manure for their fields, for which purpose it is VOL. II. 1 1 depend, than the order in which the several crops culti¬ vated are made to succeed one another. Ihe general First gene- rule is, that culmiferous crops, ripening their seeds, should ral rule- not be repeated, without the intervention of pulse, roots, herbage, or fallow. This rule is recognised in the prac- 2 p 298 AGRICULTURE. Agricul- tice and writings of all judicious cultivators, more gene- ture. rally, perhaps, than any other in the whole compass of the art of agriculture. Alternate With regard to the particular plants that enter into the system. course of cropping, these, it is evident, must be such as are suited to the soil and climate, though they will be somewhat varied by local circumstances, such as the proximity of towns and villages, where there is a greater demand for turnips, potatoes, hay, &c. than in thinly peopled districts. In general, beans, and clover with rye¬ grass, are interposed between corn crops on clayey soils, and turnips, potatoes, and clover and ryegrass, on dry loams and sands, or what are technically known by the name of turnip soils. A variety of other plants, such as peas, tares, cabbages, and carrots, occupy a part, though commonly but a small part, of that division of a farm which is allotted to green crops. This order of succession is called the system of alternate husbandry; and on rich soils, or such as have access to abundance of putrescent manure, it is certainly the most productive of all, both in food for man and for the inferior animals. One half of a farm is, in this course, always under some of the different species of Cereal gramma, and the other half under pulse, roots, cultivated herbage, or plain fallow. Convert!- But the greater part of the arable land of Britain can- ble system, not be maintained in a fertile state under this manage¬ ment ; and sandy soils, even though highly manured, soon become too incohesive under a course of constant tillage. It therefore becomes necessary to leave that division, or break, that carries cultivated herbage, to be pastured for two years or more, according to the degree of its con¬ sistency and fertility; and all the fields of a farm are treated thus in their turn, if they require it< This is called the system of convertible husbandry; a regular change being constantly going on from aration to pasturage, and vice versa. Second ge- Another rule with regard to the succession of crops, is neral rule, not to repeat the same kind of crop at too short intervals. Whatever may be the cause,—whether it is to be sought for in the nature of the soil, or of the plants themselves, experience clearly proves the advantages of introducing a diversity of species into every course of cropping. When land is pastured several years before it is brought again under the plough, there may be less need for adhering steadily to this rule; but the degeneracy of wheat and other corn crops recurring upon the same land every second year for a long period, has been very generally acknowledged. It is the same with what are called green crops; beans and peas, potatoes, turnips, and in an espe¬ cial manner red clover, become all of them much less productive, and much more liable to disease, when they come into the course, upon the same land, every second, third, or fourth year. But what the interval ought to be has not yet been determined, and (from the great num¬ ber of years that experiments must be continued to give any certain result) probably cannot be determined, until the component parts of soils, and particularly the sort of vegetable nourishment which each species of plants ex¬ tracts from the soil, have been more fully investigated. Third ge- A change of the variety, as well as of the species, and neral rule, even of the plants of the same variety, is found to be at¬ tended with advantage; and in the latter case, or a change of seed, the species and variety being the same, the prac¬ tice is almost universal. It is well known, that of two parcels of wheat, for instance, as much alike in quality as possible, the one, which had grown on a soil differing much from that on which it is to be sown, will yield a better produce than the other that grew in the same, or a similar soil and climate. The farmers of Scotland, accord¬ ingly, find that wheat from the south, even though it be A not, as it usually is, better than their own, is a very ad- ! vantageous change; and oats and other grain, brought^ from a clayey to a sandy soil, other things being equal, are more productive than such as grew on the sandy soil With these general remarks we proceed to mention the most approved rotations on the two general classes of soil, namely, what are called heavy and light, or clay and turnip soils. 1. Rotations on Clay Soils. We have already endeavoured to establish the neces-Rot sity of a naked or summer fallow on land of this descrip-on i tion; and beginning with this as the commencement ofsoil1 the course, one of the most approved rotations is,—- 1. Fallow with manure ; 2. Wheat with seeds ; 3. Red clover with ryegrass ; 4. Oats ; 5. Beans drilled and horse-hoed; 6. Wheat. In this course, manure should be applied either to the clover stubble before it is broken up for oats, or before the beans are sown. This rotation has been found to answer on clayey soils generally, but upon those of a superior quality it may be extended to eight years. In that case the order of the crops is,— 1. Fallow; 2. Wheat; 3. Beans; 4. Barley; 5. Red clover and ryegrass ; 6. Oats; 7. Beans; and 8. Wheat. Upon soils of an inferior description, or thin clays, a four years course is,— 1. Fallow with manure ; 2. Wheat; 3. Red clover and ryegrass; 4. Oats; and it is considered an improvement on this course to let the clover and ryegrass division stand to be pastured for two or three years. In that case the ryegrass should be of the perennial description ; and white clover must be added to the red in an equal or greater proportion. In particular situations, where the soil is either very rich or can be abundantly supplied with manure, it has been found profitable to cultivate wheat and beans, and wheat and potatoes, for several years in succession. 2. Turnip Soils. On the best description of such soils as do not require On a naked fallow, but which admit of turnips being grownS(J1 and consumed upon the ground, a favourite rotation is,— 1. Turnips, of which at least two-thirds should be eaten by sheep where they grow; 2. Spring wheat or barley, sown from time to time as the turnips are cleared away ; 3. Clover and ryegrass; 4. Wheat. On land of a medium quality, and without an extra- supply of manure, this has been found a very exhausting course, and ought not to be persisted in. Instead of taking two crops of wheat in the four years, it is better to take only one of wheat and one of barley; and the greater part of the clover and ryegrass should, as indeed is usually the case, be pastured the first year, instead of being cut for hay- AGRICULTURE. 299 1^ By much the greater proportion of turnip soils, how- tu . ever, do not admit even of this modified course, but re- O''' ^ nuire, after being sown with grass-seeds, to be retained in pasture for two or more years. The most common period we believe is three years, but upon sandy soils it is better to continue the land in pasturage for five or six years; and on land of this description wheat should not be at> tempted at all. The rotation would then be,— 1. Turnips, to be nearly all consumed on the ground; 2. Barley; 3. Red and white clover, with perennial ryegrass, to which is sometimes added ribwort (plantago lanceolata) and other seeds suited to such soils ; the land to be conti¬ nued in pasture for at least three years, and broken up with, 4. Oats or rye ; the latter will often be found the more profitable. . The general rule in all these cases is, that culmiferous crops ripening their seeds must never follow one another without the intervention of a fallow, or a cleansing and ameliorating crop. Though these be the rotations most generally approved by our best farmers, yet deviations from them may be permitted in particular cases without injury either to the soil or the cultivator. In the neighbourhood of large towns, and in other situations where an abundant supply of manure can be obtained, the crops are not only varied in the order of succession, but others may be substituted for some of those before mentioned. Thus, potatoes near large towns are often found more profitable than turnip, as they serve to prepare the land for wheat, which is almost always the next crop. And it is to be understood that peas, potatoes, cabbages, rape, and other green crops, are not to be considered as excluded from the general rotations; on the contrary, it is usual to sow a small pro¬ portion of peas along with the beans, and to allot part of the division under turnips for potatoes, rape, &c. * but those we have mentioned occupy the greater part of each division. Sect. VIII. Manures. Mam % Under this head we shall notice the several substances most extensively employed, with their management and application, without going into detail as to the various ar¬ ticles of this kind that are to be procured only in small quantities, or in particular situations, and which are there¬ fore used on a very limited scale. 1. Farm-yard Dung. Farm ard dung This manure, composed chiefly of the straw of grain, and the excrementitious substances of live stock, is the principal, and in most instances the only fertilizer of the soil to which farmers have access. Its use is so universal and so well known, that a very few observations will suf¬ fice. As straw is the basis of this compost, every judicious farmer takes care to have his crops cut as low as possible, as it is evident to every one that a few inches of straw towards the root-end adds much to the weight of the crop. From every ton of dry straw about three tons of farm-yard dung may be obtained, if the after-management be properly conducted; and as the weight of straw per acre runs from 1 ton to IV about 4 tons of dung, on an average of the different crops, may be produced from the straw of every acre under corn. (Husbandry of Scotland, vol. ii.) The straw is served out to cattle and horses in the houses and fold-yards, either as provender or litter, com- monly for both" purposes; and turnips in winter, and green clover in summer, on which food the animals pass a Agricul- * great deal of urine, afford the means of converting the ture. straw into a richer manure than if it were all eaten by itself, All the dung from the houses, as they are cleaned out, ought to be regularly spread over the yards, in which young cattle are left loose, where litter is usually allowed in great abundance ; or over the dunghill itself, if there be one at hand. This renders the quality of the whole mass more uniform; and the horse-dung, which is of a hot na¬ ture, promotes the decomposition of the woody fibres of the straw. At a convenient season, usually during the frosts of Manage- winter, this mass of materials is carted out to the field toment.h which it is to be applied, and neatly built in dunghills of a square form, three or four feet high, and of such a length and breadth as circumstances may require. What is laid up in this manner early in winter is commonly sufficiently prepared for turnips in June ; but if it be not carried from the straw-yards till spring, it is necessary to turn it once or oftener, for the purpose of accelerating the decomposi¬ tion of the strawy part of the mass. When dung is ap¬ plied to fallows in July or August, preparatory to autumn- sown wheat, a much less degree of putrefaction will suf¬ fice than for turnips—a clay soil, on which alone fallows should ever be resorted to, not requiring dung so much rotted as a finely pulverized turnip soil; and besides, as the wheat does not need all the benefit of the dung for some time, the woody fibre is gradually broken down in the course of the winter, and the nourishment of the plants continued till spring or later, when its effects are most be¬ neficial. In the application of dung to land under tillage, parti- Applica- cular attention should be paid to the cleanness of the soil, tion. and to use it at the time when, from the pulverization of the ground, it may be most intimately mixed with it. The most common time of manuring with farm-yard dung is, therefore, either towards the conclusion of the fallowing operations, or immediately before the sowing of fallow crops. If no dung can be procured but what is made from the produce of the farm, it will seldom be possible to al¬ low more than ten or twelve tons to every acre, when the land is managed under a regular course of white and green crops; and it is thought more advantageous to repeat this dose at short intervals, than to give a larger quantity at once, and at a more distant period in proportion. (Gene¬ ral Report of Scotland, vol. ii. p. 517.) Farm-yard dung, it is well known, is greatly reduced in value by being exposed to the atmosphere in small heaps previous to being spread, and still more after being spread. Its rich juices are exhaled by the sun, or washed away by the rains, and the residuum is comparatively worthless. This is in an especial manner the case with long fresh dung, the far greater part of which consists of wet straw in an entire state. All careful farmers, accordingly, spread and cover in their dung with the plough as soon as possible after it is brought on the land. It has been urged by a celebrated chemist, that farm-Fresh yard dung ought not to be allowed to ferment in any con-dung, siderable degree, as during a violent fermentation a large quantity not only of fluid but likewise of gaseous matter is lost, which, if retained by the moisture in the soil, would be capable of becoming a useful nourishment to plants. He therefore recommends that it should be ap¬ plied after a slight incipient fermentation, which he admits to be useful in "bringing on a disposition in the woody fibre to decay and dissolve; and this is always, he adds, in great excess in the refuse of a farm. (Davy s Agricultu¬ ral Chemistry, p. 302. 8vo.) From a recent publication (Husbandry of Scotland, 300 AGRICULTURE. Agricul- vol. i. p. 174), the practice of the best farmers of turnip soils ture. in Scotland appears to be decidedly adverse to the use of fresh dung; and its inutility, or rather injurious effects, from its opening the soil too much, is a matter of expe¬ rience with every one who cultivates drilled turnips on a large scale. As the whole farm-yard dung on such land is applied to the turnip crop, it must necessarily happen that it should be laid on in different stages of putrefaction ; and what is made very late in spring, often after a very slight fermentation, or none at all. The experience of the effects of recent dung is accordingly very general, and the result in almost every case is, that the growth of the young plants is slow,—that they remain long in a feeble and doubtful state,—and that they seldom, in or¬ dinary seasons, become a full crop, even though twice the quantity that is given of short muck has been allowed. On the other hand, when the manure is considerably de¬ composed, the effects are immediate, the plants rise vigor¬ ously, and soon put forth their rough leaf, after which the beetle or fly does not seize on them; and in a few weeks the leaves become so large, that the plants probably draw the greater part of their nourishment from the atmosphere. Though it were true, therefore, that more nutritive matter were given out by a certain quantity of dung ap¬ plied in a recent state, and allowed to decompose gra¬ dually in the soil, than if applied after undergoing fermen¬ tation and putrefaction, the objection arising from the slowness of its operation would, in many instances, be an insuperable one with farmers. But there seems reason to doubt whether fresh strawy manure would ferment much in the soil, after being spread out in so small a quantity as has been already mentioned; and also, whether in the warm dry weather of summer, the shallow covering of earth given by the plough would not permit the gaseous matters to escape to a much greater amount than if fermentation had been completed in a well-built covered dunghill. Another great objection to the use of fresh farm-yard dung is, that the seeds and roots of those plants with which it commonly abounds spring up luxuriantly on the land; and this evil nothing but a considerable degree of fermentation can obviate. The mass of materials consists of the straw of various crops, some of the grains of which, after all the care that can be taken, will adhere to the straw,—of the dung of different animals, voided, as is often the case with horses fed on oats, with the grain in an en¬ tire state,—and of the roots, stems, and seeds of the weeds that had grown among the straw, clover, and hay, and such as had been brought to the houses and fold- yards with the turnips and other roots given to live stock. No rule of universal application can be laid down on this subject; the degree of decomposition to which farm¬ yard dung should arrive before it can be deemed a profit¬ able manure, must depend on the texture of the soil, the nature of the plants, and the time of its application. In general, clayey soils, more tenacious of moisture, and more benefited by being rendered incohesive and porous, may receive manure less decomposed than well-pulverized turnip soils require. Some plants, too, seem to thrive better with fresh dung than others,—potatoes in particu¬ lar ; but all the small-seeded plants, such as turnips, clo¬ ver, carrots, &c. which are extremely tender in the early stage of their growth, require to be pushed forward into luxuriant vegetation with the least possible delay, by means of short dung. The season when manure is applied is also a material circumstance. In spring and summer, whether it be used for com or green crops, the object is to produce an immediate effect, and it should therefore be more completely decomposed than may be necessary when it is laid on in autumn for a crop whose condition A will be almost stationary for several months. 2. Lime. ^ Next to farm-yard dung, lime is in most general use asljj a manure, though it is one of a quite different character- and when judiciously applied, and the land laid to pas¬ ture, or cultivated for white and green crops alternately, with an adequate allowance of putrescent manure, its ef¬ fects are much more lasting, and in many instances still more beneficial, than those of farm-yard dung. Fossil manures “ must produce their effect, either by becoming a constituent part of the plant, or by acting upon its more essential food, so as to render it more fitted for the pur¬ poses of vegetable life.” (Davy's Agricultural Chemistry, p. 314.) It is perhaps in the former of these ways that wheat and some other plants are brought to perfection after lime has been applied upon land that would not bring them to maturity by the most liberal use of dung alone. “ The most common form in which lime is found on the surface of the earth, is in a state of combination with car¬ bonic acid or fixed air. If a piece of limestone or chalk be thrown into a fluid acid, there will be an effervescence. This is owing to the escape of the carbonic acid gas. The lime becomes dissolved in the liquor. When limestone is strongly heated, the carbonic acid gas is expelled, and then nothing remains but the pure alkaline earth ; in this case there is a loss of weight, and if the fire has been very high, it approaches to one-half the weight of the stone; but in common cases, limestones, if well dried be¬ fore burning, do not lose much more than from 35 to40Lo per cent., or from seven to eight parts out of twenty, we When burned lime becomes mild, it regains its power of^ul S- effervescing, and is the same chemical substance as chalk or limestone. “ When newly burned lime is exposed to air, it soonSla falls into powder; in this case it is called slacked lime;!™ and the same effect is immediately produced by throwing water upon it, when it heats violently and the water dis¬ appears. Slacked lime is merely a combination of lime with about one-third of its weight of water, that is* 55 parts of lime absorb 17 parts of water. “ When lime, whether freshly burned or slacked, is Op mixed with any moist fibrous vegetable matter, there is a of strong action between the lime and the vegetable matter, and they form a kind of compost together, of which a part is usually soluble in water. By this kind of operation, lime renders matter which was before comparatively inert nutritive; and as charcoal and oxygen abound in all vege¬ table matters, it becomes at the same time converted into carbonate of lime. “ Mild lime, powdered limestone, marls, or chalks, have no action of this kind upon vegetable matter; by their action they prevent the too rapid decomposition of substances already dissolved, but they have no tendency to form soluble matters. “ It is obvious, from these circumstances, that the ope¬ ration of quicklime and marl or chalk depends upon prin¬ ciples altogether different. Quicklime, in being applied to land, tends to bring any hard vegetable matter that it contains into a state of more rapid decomposition and so¬ lution, so as to render it a proper food for plants. Chalk and marl, or carbonate of lime, will only improve the tex¬ ture of the soil, or its relation to absorption ; it acts mere¬ ly as one of its earthy ingredients. Quicklime, when it becomes mild, operates in the same manner as chalk; but, in the act of becoming mild, it prepares soluble out of insoluble matter. AGRICULTURE. u] << The solution of the question, whether quicklime ^ti * ought to be applied to a soil, depends upon the quantity 0f inert vegetable matters that it contains. The solution of the question, whether marl, mild lime, or powdered limestone, ought to be applied, depends upon the quanti¬ ty of calcareous matter already in the soil. All soils are improved by mild lime, and ultimately by quicklime, which do not effervesce with acids, and sands more than clays.” (Davy’s Agricultural Chemistry, p. 315, et seq.') From the mode in which lime operates, it necessarily follows that quicklime should not be applied to lands that contain much soluble matter, nor be mixed up in com¬ posts with animal manures. Macisian “ It had been long known to farmers in the neighbour- lime ne. hood of Doncaster, that lime made from a certain lime¬ stone, applied to the land, often injured the crops consider¬ ably. Mr Tennant, in making a series of experiments upon this peculiar calcareous substance, found that it con¬ tained magnesia; and on mixing some calcined magnesia with soil, in which he sowed different seeds, he found that they either died, or vegetated in a very imperfect manner, and the plants were never healthy. And, with great justice and ingenuity, he referred the bad effects of the peculiar limestone to the magnesian earth it contains.” (Id. p. 322.) Yet it is advantageously employed in small quantities, seldom more than 25 or 30 bushels to the acre. A simple test of magnesia in the limestone is the circum¬ stance of its effervescing little when plunged into an acid, and its rendering diluted nitric acid or aquafortis milky. Stones of this kind are usually coloured brown or pale yellow, and are found in several counties of England, and in many parts of Ireland, particularly near Belfast. With regard to the quantity of lime that ought to be pplii to applied to different soils, it is much to be regretted that Sir Humphry Davy did not enter fully into the sub¬ ject. Clays, it is well known, require a larger quantity than sands or dry loams. It has been applied, accord¬ ingly, in almost every quantity from 100 to 500 bushels or upwards per acre. About 160 bushels are generally considered a full dressing for lighter soils, and 80 or 100 bushels more for heavy cohesive soils. In the application of lime to arable land, there are some general rules commonly attended to by diligent farmers, of which we shall present an abstract. 1. As the effects of lime greatly depend on its intimate admixture with the surface soil, it is essential to have it in a powdery state at the time it is applied. 2. Lime having a tendency to sink in the soil, it should be ploughed in with a shallow furrow. 3. Lime may either be applied to grass land, or to land in preparation for green crops or summer fallow, with almost equal advantage; but, in general, the latter mode of application is to be preferred. 4. Lime ought not to be applied a second time to moorish soils, unless mixed up as a compost; after which the land should be immediately laid down to grass. 5. Upon fresh land, the effect of lime is much superior to that of dung. The ground, likewise, more especially .ere it is of a strong nature, is more easily cultivated; m some instances, it is said, “ the saving of labour would e efficient to induce a farmer to lime his land, were no greater benefit derived from the application than the op¬ portunity thereby gained of working it in a more perfect manner. ( General Report of Scotland, vol. ii. p. 536.) me i m_ In improving hilly land with a view to pasture, a much novir srila er quantity of lime has been found to produce per- ''■'v td nianent and highly beneficial effects, when kept as much »iil dll i as possible near the surface, by being merely harrowed in We. With the seeds, after a fallow or green crop, instead of be¬ 301 Agricul¬ ture- Quality differ! t toil;.! Gent1! rules-; Effect] f iuie ing buried by the plough. As this is a matter of much importance to farmers of such land, especially when lime must be brought from a great distance, as was the case in^^^ the instance to which we are about to allude, the success¬ ful practice of one of the most eminent farmers in Britain cannot be too generally known. “ A few years after 1754,” says Mr Dawson, « having a considerable extent of outfield land in fallow, which I wished to lime previous to its being laid down to pasture, and finding that I could not obtain a sufficient quantity of lime for the whole in proper time, I was induced, from observing the effects of fine loam upon the surface of si¬ milar soil, even when covered with bent, to try a small quantity of lime on the surface of this fallow, instead of a larger quantity ploughed down in the usual manner. Ac¬ cordingly, in the autumn, about twenty acres of it were well harrowed, and then about fifty-six Winchester bush¬ els only, of unslacked lime, were, after being slacked, carefully spread upon each English acre, and immediate¬ ly well harrowed in. As many pieces of the lime, which had not been fully slacked at first, were gradually reduced to powder by the dews and moisture of the earth,—to mix these with the soil, the land was again well harrowed in three or four days thereafter. This land was sown in the spring with oats, with white and red clover and rye¬ grass seeds, and well harrowed, without being ploughed again. The crop of oats was good, the plants of grass sufficiently numerous and healthy; and they formed a very fine pasture, which continued good until ploughed some years after for corn. “ About twelve years afterwards I took a lease of the hilly farm of Grubbet, many parts of which, though of an earthy mould tolerably deep, were too steep and ele¬ vated to be kept in tillage. As these lands had been much exhausted by cropping, and were full of couch- grass, to destroy that and procure a cover of fine grass, I fallowed them, and laid on the same quantity of lime per acre, then harrowed and sowed oats and grass-seeds in the spring, exactly as in the last mentioned experiment. The oats were a full crop, and the plants of grass abund¬ ant. Several of these fields have been now above thirty years in pasture, and are still producing white clover and other fine grasses : no bent or fog has yet appeared upon them. It deserves particular notice, that more than treble the quantity of lime was laid upon fields adjoining of a si¬ milar soil, but which being fitter for occasional tillage, upon them the lime was ploughed in. These fields were also sown with oats and grass-seeds. The latter throve well, and gave a fine pasture the first year; but after¬ wards the bent spread so fast, that in three years there was more of it than of the finer grasses.” The conclusions which Mr Dawson draws from his ex¬ tensive practice in the use of lime and dung, deserve the attention of all cultivators of similar land. “ 1. That animal dung dropt upon coarse benty pas-Condu- tures produces little or no improvement upon them; and sions as to that, even when sheep or cattle are confined to a small theeTects space, as in the case of folding, their dung ceases to duce any beneficial effect after a few years, whether the land is continued in pasture or brought under the plough. “ 2. That even when land of this description is well fal¬ lowed and dunged, but not limed, though the dung aug¬ ments the produce of the subsequent crop of grain, and of grass also for two or three years, that thereafter its effects are no longer discernible either upon the one or the other “ 3. That when this land is limed, if the lime is kept upon the surface of the soil, or well mixed with it, and then laid down to pasture, the finer grasses continue in possession of the soil, even in elevated and exposed situa- 302 AGRICULTURE. Agricul¬ ture. Quantity of calcar¬ eous mat¬ ter in dif¬ ferent limestones tions, for a great many years, to the exclusion of bent and fog. In the case of Grubbet-hills, it was observed, that more than thirty years have now elapsed. Besides this, the dung of the animals pastured upon such land adds every year to the luxuriance, and improves the quality of the pasture, and augments the productive powers of the soil when afterwards ploughed for grain ; thus producing, upon a benty outfield soil, effects similar to what are ex¬ perienced when rich infield lands have been long in pas¬ ture, and which are thereby more and more enriched. “ 4. That when a large quantity of lime is laid on such land, and ploughed down deep, the same effects will not be produced, whether in respect to the permanent fine¬ ness of the pasture, its gradual amelioration by the dung of the animals depastured on it, or its fertility when after¬ wards in tillage. On the contrary, unless the surface is fully mixed with lime, the coarse grasses will in a few years regain possession of the soil, and the dung thereafter deposited by cattle will not enrich the land for subsequent tillage. “ Lastly, It also appears from what has been stated, that the four-shift husbandry is only proper for very rich land, or in situations where there is a full command of dung; that by far the greatest part of the land of this country requires to be continued in grass two, three, four, or more years, according to its natural poverty; that the objection made to this, viz. that the coarse grasses in a few years usurp possession of the soil, must be owing to the surface soil not being sufficiently mixed with lime, the lime having been covered too deep by the plough.” {Far¬ mers Magazine, vol. xiii. p. 69.) Limestones differ much in purity, or in the quantity of calcareous matter which they contain. According to Mr Headrick {Farmers Magazine, vol. v. p. 451) it is usual¬ ly from 60 to 85 per cent.; but he afterwards analyzed some limestones from the county of Fife, which contained 99^ per cent, of carbonate of lime, the residuum being fine clay. Farmers generally estimate the purity of lime¬ stones by the quantity of slacked lime produced from a given quantity of burnt limestone, or shells as it is usually called, the pulverized lime of the best shells being three times the measure of the shells. But it is easy to ascer¬ tain the quantity of calcareous matter in the stone itself, by the use of muriatic acid; that stone being the best which leaves the least sediment, the lime itself dissolving in the acid. 3.

Marl, which was more extensively employed as a manure in former times than it has been of late, since the properties of lime have been better understood, is usually divided into stone, clay, and shell marl, of which the last is the most valuable. All marls contain a portion of cal¬ careous matter, and their operation is not materially differ¬ ent from that of mild lime, as has been formerly noticed; but the greater quantity required, owing to the smaller proportion of calcareous matter which they contain, confines the use of them to a few miles around the places where they are found. The effects of marl are slower than those of quicklime, but, from the earthy substances combined with the calcareous matter, and the larger quantity usual¬ ly applied, the staple of the soil is deepened, and the bene¬ fit is considered more durable.

It should be applied fresh as it is gathered, if the land be ready to re- Bones are a source of manure too little attended to in Bi most places, though their value is well ascertained by a pretty extensive experience of their effects in several dis¬ tricts. The following particulars were transmitted from Yorkshire, in answer to some queries proposed by the writer of this article. “ 1. It is thought that all the bones of every animal are not equally valuable; but all the bones of an animal suit¬ able for manure are equally good, and are much better when fresh. “ 2. The bones which are best filled with oil and mar¬ row are certainly the best manure; and the parts gene¬ rally used for buttons and knife-hafts are the thigh and shank-bones. “ 3. The powdered bones are dearer, and generally used for hot-beds in gardens, being too expensive for the field, and not so durable a manure as bruised bones, though for a short time more productive. “ 4. A dry, light or gentle soil, is best adapted for the use of bone manure, as it is supposed that, in land which retains wet, the nutritive part of the bone washes to the surface of it, and does not incorporate sufficiently with the soil. “ 5. The autumn is the most proper time for the use of this manure, which should then be laid on fallows fora turnip crop. The powder only should be used on a green crop, as the bruised bones would interrupt the progress of the scythe. “ 6. The effects produced on different crops are gene¬ rally good on such soil as named in No. 4. “ 7. Bruised bones are better when mixed with ashes or any other manure, as the juice of the bones is then more equally spread over the field. “ 8. Bone manure ought to be ploughed into the land in tillage. On grass, the powder should be sown in by the hand. “ 9. This manure is used on land before described, to the extent of several thousand acres, in the higher parts of Nottinghamshire, and the wolds (or high land) in Lin¬ colnshire, and the East and West Riding of Yorkshire. “ 10. The primary object of keeping a bone mill is the bruising of bones, which pays better, than selecting and selling such as are suitable for buttons, &c. “ 11. In an agricultural district, where the generality 5: of the land is of the nature before mentioned as best suit-^1 ed for bone manure, a mill for the purpose of bruising bones would certainly indemnify the proprietors. The cost of a mill is from L.100 to L.200. As to the number of miles the manure may be carried, the proprietors of the mill will be best able to judge of that.” See Plate X. The use of bones as a manure has been only recently in¬ troduced into Scotland; but the experiments, as far as they have gone, are highly satisfactory, and the practice is rapidly extending. The following account of some of these experiments, I - extracted from the Quarterly Journal of Agriculture, is n given by the gentleman who made them, Mr Watson of Keillor, near Cupar-Angus, in a communication dated in February 1828. Mr Watson obtained bone manure for two acres in 1821, the greatest quantity recommended being 25 bushels for the Scotish acre. “ This,” says he, “ 1 applied, the following turnip-sowing season, to two acres of a field of sharp black land on this farm, and on two ad¬ joining acres of the same field I applied 25 cart-loads per acre of well-made farm-yard dung. The season, at time AGRICULTURE. 303 of sowing, was rather wet, and not very favourable for the tur first growth of turnips. Those with bones came above SV'J ground on the third day very dark coloured and broad in the leaf, and by the tenth day they were all in the rough blade. At this time I examined the state of the manure, and found it one mass of maggots; but two days after they were all dead; and the weather being now dry and warm, the most rapid vegetation I ever remarked took place; so that by the fifteenth day from time of sowing, the turnips were fully strong for being thinned out. This operation I had performed by women, pulling out the spare plants with their hands (being afraid to remove any part of the manure from the roots of the plants) ; but I have since found that the common turnip-hoe, carefully used, does the work very well, and leaves the manure un¬ disturbed. “ The plants where the farm-yard dung was applied did not come up till the fifth day, and the turnips were twenty days sown before they were fit for being thinned. By this time the bone turnips were meeting on the top of the drill, and they continued to maintain the advantage of their first start until the month of September, which set in rather dry. At this time I anticipated that the bones would be exhausted, and the crop stop growing; but such was not the case, for while the dunged crop be¬ gan to fade and stop growing, the bone turnip kept grow¬ ing vigorously. About the middle of October, when I considered both crops at maturity, I had a comparative trial of their weight carefully made, the result of which was six tons per acre in favour of the bones,—they being 28 tons per acre of Aberdeenshire yellow turnip, and the farm-yard dung only 22 tons per acre. “ From this experiment, and the valuable information I had now obtained through my friend Mr Healy of Lough- ton, in Lincolnshire, I was induced to extend the use of bones on my farms, growing annually from 70 to 100 acres of turnips with this manure, which gives me a great com¬ mand of dung for my other crops. In 1823 I erected machinery for grinding bones, my neighbours having now all become convinced of their great utility; and the first season I sold to the amount of L.1500 worth. This last season, not less than L.10,000 has been paid for bones used in this district of Strathmore, in the counties of Angus and Perth, a great part of which was commissioned from Hull. There are now machines erected for grind¬ ing bones in various parts of the country; so that the ex¬ pense of inland carriage is in many cases much lessened. “ The general practice is, to use bones on dry light soils, where the turnip can be eat off the ground with sheep, in such proportion (not less than one half) as may he reckoned necessary to manure the ground for an after- crop of oats or barley. The quantity of bone manure may be varied from 15 to 25 bushels of dust per acre, accord¬ ing to the state of the land. Some difficulty was at first ound in depositing the bones so that the plants might reap all the benefit of it; but this is now obviated by the application of two additional hoppers and spouts to the turnip sowing machine, which conduct the manure and seed into the drill at the same time, and with the same expedition as sowing the seed by the old machine. These >airows are made by most carpenters in the country, and cost about L.8. ^ ^ •r’ Doubts have been raised whether the succeeding erop of oats or barley is in any degree benefited by the sum quantity of bones used in growing a crop of turnips. ..can confidently state, that on my farms both the quan- y and quality, of my barley particularly, have been im>- proved, and the grass for the first year is a fortnight ear- ler m its growth than after other manures. ture. in the crop of 18;.5 the bone manure was a great Agricul- blessing to the breeders and feeders of cattle in this dis¬ trict, and in some instances saved the industrious tenantv from rum. The severe drought even of that season did not prevent a crop of turnips with bones, while all other manures failed; and it was thus the means of bringing through that disastrous winter, herds of cattle which must have otherwise perished for want of fodder.” Horn, says Sir H. Davy, is a still more powerful manure than bone, as it contains a larger quantity of de¬ composable animal matter. The shavings or turnings of horn, though they cannot be procured in great abundance, are much esteemed as a manure, and have been lono- known to the farmers in the west of Scotland, who some^ times bring them from Ireland. They are sown by the hand as a top-dressing for wheat and other crops. 6. Burnt Clay. This is a mode of preparation which was introduced Burnt into the west of Scotland some years ago from Ireland, by clay. Mr Craig at Cally, in the stewartry of Kirkcudbright. That its effects have been beneficial in many cases can¬ not well be doubted, and it is still in use by some very intelligent cultivators. But, as frequently happens, it was recommended too warmly and in too unqualified a manner by its earliest promoters; and experience in many in¬ stances not having confirmed their statements, it has of late fallen into disrepute, and is now but little employed. It will therefore be sufficient to refer to the Farmer s Magazine, vol. xvi., where the practice is treated at some length by those who first brought it into notice. 7. Miscellaneous Articles. We shall now mention some of those numerous vege¬ table, animal, and other substances, which, though not in general use as manures, are sometimes employed for that purpose, in particular situations. It had been long known that moss or peat, made up Meadow- in compost with farm-yard dung, affords a valuable ma- bank ma¬ nure; but it was first introduced to general notice bynure. the late Lord Meadowbank. The usual proportions may be about two-thirds of moss and one-third of farm-yard dung, spread out in layers, one above another, in form¬ ing the dung heap, but the bottom and top should be of moss. This heap in a few days acquires a considerable degree of heat, indicating the progress of the process of fermentation. It is then turned over, and made up again with or without a further addition of moss and dung. When this corppost has been properly managed, the whole heap forms a homogeneous mass, moist, black, friable, and excellently adapted to turnips, and all other crops that require rotted dung. No lime or other calcare¬ ous matter should be admitted into the compost. The same object of increasing the quantity of manure may be obtained by carting the moss to the farm-yard in which cattle are kept, where, without any further trouble, it will become mixed up with their litter and dung, and be carted out to the fields in one mass. Some very interesting and successful experiments have Experi- been made with oil mixed up with farm-yard dung and meats with moss, by Mr William Bell, on his estate in Roxburghshire. 0'1in com- We have entire confidence in the accuracy of this gentle-P^'^1 man’s statements, and present them in his own words in a^u0^ant recent communication to the Highland Society of Scotland. “ The object in view in the experiment now to be de¬ tailed, was to procure the means of converting moss, or other decayed vegetable substance, into a rich top-dress¬ ing, in a situation so far inland, that the expense of car¬ riage from the sea-coast (L.2. 5s. per ton) precluded the 304 AGRICULTURE. Agricul- use, with any expectation of profit, of blubber, bone, rape- ture. dust, or other similar substances. Attention had been y drawn to oil as a manure, by the practice of the Flemings, in forming their liquid dung-pits, and by the fact that, in the use of blubber and rape-cake for this purpose, the benefits following their application are in the precise pro¬ portion of the inefficacy of the means employed for ex¬ pressing the oil from them. It was also conceived, that, to a certain extent at least, the nutritious matter contain¬ ed in bone-dust may be traced to the oleaginous particles of the bony substance. “ It was resolved to commence with one ton of oil, and such a proportion of moss as, in all probability, that quan¬ tity of oil could easily convert by heating, into a more profitable substance. “ It was further resolved, that the process of heating should be aided by a certain quantity of stable-dung, and that 250 cubic yards of moss to the ton of oil should, in the first instance, be tried with 25 cubic yards of dung,, though it was expected that a much greater quantity of moss might be fully converted into manure by that quan¬ tity of oil and dung. “ A ton of “ dreg,” or coarse whale-oil, therefore, cost¬ ing L.16, was purchased at Leith, and sent out at the cost of L.2. 10s. In the beginning of June 1825, a bed was formed a foot thick of moss, which had been thrown out some time before, but which still retained all its peaty qualities, and which, though still moist, yet having lain in a heap for some months, was substantially freed of much of its superfluous moisture. “ Twenty-five cubic yards of good stable-dung were then laid in a thick layer upon this bed; above which, another layer of moss was laid, fully a foot thick. On this second layer of moss the whole quantity of oil was poured, and the residue of the moss was laid above all, and along the sides, so as completely to cover the whole well up. “ In ten days the whole mass came freely into heat. It was turned after an interval of about eight weeks, when it was found to have been greatly changed in its texture and quality. After having been so treated, it heated freely again, and, on inspection, was found to have been altogether altered. It had now all the appear¬ ance of the richest possible black garden-mould, and was quite full of large, fat earth-worms. It gave out a strong oily smell, from which it was inferred that too little moss had been used; and some apprehension was entertained as to its fitness for being applied to its primary destina¬ tion,—a top-dressing fqr grass-land. “ The costs were as follows :— Oil and carriage, L. 18 10 0 Twenty-five cubic yards stable-dung, at 5s., the usual price of the country, 6 5 0 L.24 15 0 “ No charge for casting the peat is made, both because in this instance it was desirable to consume the substance which had been thrown out of the ditches, and because the compound lay contiguous to the ground on which it was to be used, while the cost of casting and turning was deemed equivalent to the carriage afield of the manure that would have been required. 260 cubic yards compound, at Is. ll^d., about L.25 3 9 “ The farm-steward was of opinion that the produce was so rich as safely to admit of its being used in equal quantities with ordinary farm-dung. Two several por¬ tions of land, each of half an acre, were accordingly de¬ voted to a trial of its powers on that principle 4 the one, rich old turnip soil, worth 40s. of rent per English acre ; the other, new turnip land, which had never been broken J up. These portions were laid off in the centre of the two several fields, and the manure was applied to the turnip'- crop in the usual way. The other parts of both fields were dunged with farm-yard manure,—equal quantities of it and of the compound being given to the acre. The summer 1826 was not favourable to turnip-crops gene¬ rally ; but it so happened that the crops on both these fields were very, great. “ On the old land, the turnips grown with the oil com- pound sprung earlier than on the rest of the field, grew larger, and were more luxuriant, and very decidedly kept the lead, both in root and shaw, during the whole season; but absence from the spot prevented a minute register of weight and measure being kept. “ On the new land, no difference could be distinguished betwixt the crop from the two several manures: both were so good, that better could scarce have grown. “ In the next crop (oats on both fields), though mi¬ nutely inspected, no difference in produce could be de¬ tected ; but the same causes prevented the circumstances of the case being duly attended to. “ This year both fields are in grass, and both will be hayed. At present (30th June) no difference can be detected. “ No inconvenience from the oily smell was felt when the residue of the compost was applied to grass-land. It was laid on early, and the ground was hayed. It was given to the meadows last improved, and therefore the least advanced; while rush-root compound, and other substances, were given to the older portions. The crop on each was very great; but the preference was rather given to the oil. “ These results were so far encouraging, that next year, 1826, two tons of oil were purchased at the price of L. 14 per ton, and used with rather less than 90 cubic yards of manure, and fully 900 of moss. About 550 cu¬ bic yards were used in the first instance, in the same man¬ ner as on the former occasion, and the residue of 350 thrown in when the compound was turned. It is now be¬ lieved, however, that it would have been better to have made up the whole at once, by adding to the thickness of the several layers of moss, especially the centre one. “ The cost on this occasion was as follows:— Oil, two tons, and carriage, L.33 0 0 90 cubic yards manure, at 5s. per yard, 22 10 0 990 cubic yards compound, at Is. Ifd., about...56 13 9 “ The result again was very satisfactory; the moss heated fully the first time, and freely the second, not¬ withstanding the error committed,—the result of which was apparently to check the second fermentation a little, and to leave lumps here and there not quite decomposed. But the whole has been substantially and effectually changed, and confirms, in every respect, the result of tne former experiment. “ On both occasions, moss thrown out at the same time remained altogether unchanged : while the one was luxu¬ riantly covered with vegetable growth, the other contin¬ ued a sterile heap. “ This year, five tons of oil have been bought at L.9 per ton, and carriage 40s LJ>5 0 On the same principle as before, the dung will cost, for 225 cubic yards, at 5s 56 5 To be used with 2250 cubic yards of moss,....Ill 5 2475 cubic yards produce, at 10|d., about...110 ^ ^ “ The effect of these operations is probably twofo (• In the first place, the oil, thus divided, may be renderei a fit element for the nutrition of plants; and, in the se¬ cond place, unquestionably much benefit is secured by die AGRICULTURE. a , ,1- change effected on the substance of the peaty matter, fu • Fullyb the larger share of benefit is ascribed to this cir- v^ ^cumstance ; but, at the same time, it is very probable that it may be found by experiment that oil may with great advantage be used with every other species of manure, or even with compounds of purely earthy ingredients.” Manure, in a liquid state, is used to a considerable ex¬ tent in Flanders, where the utmost attention is paid to the collecting of every substance that can serve to enrich the soil. This consists of urine in which rape-cake has been dissolved, the former being collected in subterra¬ neous drains of brick-work, from which it is raised by a temporary pump, and delivered into carts for being car¬ ried to the field, where it is spread by means of hollow shovels or scoops. This is the manure almost universally used for the flax crop, to which it is applied at the rate of about 2500 gallons English beer measure the acre. Sait.. Salt has been warmly recommended within these few years as a valuable manure, and at the same time for its property in destroying weeds. The recent repeal of the duties on salt has rendered this substance accessible to farmers in every part of the country; and it has been subjected to a variety of experiments. These, as might be expected, have not always given the same results ; but the best attested experiments do not seem to have been attended with such success as to justify the encomiums that were at one time lavished upon this substance; and the general impression among farmers is, that it is of little or no value whatever as a manure. We are aware that a difference of opinion still exists on this point; but such is the opinion we have come to, on what we conceive to be the best authorities. Of the substances of vegetable or animal origin occa¬ sionally or locally applied in this way, the number is very Sum nt great. All green succulent plants add to the fertility of plant soii when ploughed into it; and it is by no means uncom¬ mon to cultivate buck-wheat and other plants expressly for this purpose. Thistles, docks, and other noxious weeds, which at any rate should be always cut down before form¬ ing their seeds, may be advantageously used as manure, and are sometimes mixed with farm-yard dung when laid llapc.ke.out f° ferment, in the manner already described. Rape- cake is an excellent dressing for turnips, and is most eco¬ nomically applied when thrown into the soil at the same ’s time with the seed.1 By covering dead animals with five d 1 1 or six times their bulk of soil, mixed with one part of lime, and suffering them to remain for a few months, their decomposition impregnates the soil with soluble matters, so as to render the mass an excellent manure; and by mixing a little fresh quicklime with it at the time of its p removal, the disagreeable effluvia may be in a great mea¬ sure destroyed.2 3 Fish are well known to be a powerful ma¬ nure, though the quantity should be limited. A full crop of turnips has been got from spoiled herrings laid on before Clu1! ^le w‘nter ploughing, at the rate of twenty-five barrels to an acre.0 Blubber has been used with great success by Eord Somerville, mixed with clay, sand, or any common sod, so as to expose a large surface to the air ;4 but it has been found injurious in some instances,5 probably owing to •ts having been applied too largely, as has happened in the case of fish, or from not having been combined with a suf¬ ficient quantity of soil. The refuse of the different manu- Agricul- factures of skin and leather affords very useful manures, ture. such as the shavings of the currier, furriers’ clippings, and the offals of the tan-yard and of the glue-maker.

Night-soil is a most powerful manure. Night-soil. The disagreeable smell may be destroyed by mixing it with quicklime. The Chinese mix it with one-third of its weight of fat marl, make it into cakes, which are said to be a common article of commerce, and dry it by exposure to the sun.6 Next to this, in its fertilizing powers, is pigeons' dung, commonly used in a dry state as a top- Pigeons’ dressing, at the rate of about twenty bushels to an acre.7 dung. Manures of a mineral or fossil origin are also numerous. Lime- Limestone gravel, which abounds in Ireland, chalk, pound- stone ed limestone, sea-shells, and shelly sand, are all employed, gravel, &c. some of them to a considerable extent, in much the same manner as lime; but their effect, though durable, is not so immediate. Gypsum, or sulphate of lime, is found in Gypsum, several parts of England, but its value as a manure does not yet appear to be clearly determined. It does not seem to operate by accelerating putrefaction,8 but it is sup¬ posed that lands which have ceased to bear good crops of clover or cultivated grasses may be restored by being manured with gypsum, as it is found in considerable quantities in their ashes.9 Soot is known to be a useful Soot, top-dressing, either by itself or when mixed with earth and lime, in the proportion of one part soot, five parts earth, and one part lime ;10 but its effects are not lasting. Sleech or sea-ooze, .containing animal and vegetable sub- Sleech. stances, with a large proportion of calcareous matter, affords a valuable dressing, increasing the staple of the soil to which it is applied, as well as its fertility. Pond Mud. and river-mud, mixed with lime, has been often applied with good effect. Even coal-sill or schistus has been used Schistus. with much advantage by Mr Curwen and others, after being decomposed with lime, in the proportion of one part of the latter to six of the former.11 The great quantity of valuable manure obtained from Town large towns is a mixture of almost all these ingredients ; and what was formerly a nuisance is now a source of re¬ venue to the inhabitants, and of fertility to the country around them. In several districts land is manured on the surface, by Folding, cattle and sheep confined in temporary folds. See the chapter on Live Stock, where the benefits of this practice will be inquired into. Its expediency is a question that can¬ not be determined without a reference to its effects on the animals themselves, as well as to the value of the manure. Sect. IX. Warping. This is a mode of fertilizing lands, by depositing a coat Warping, of alluvial matter on their surface, and is practised on the borders of large rivers and estuaries into which the tides flow. It is said to have been first tried on the banks of the Humber about a century ago, but was first brought into notice by Marshall in 1788, and afterwards by the Report of the West Riding of Yorkshire. A similar praC“ tice has been long known in Italy. 1 Davy’s Agricultural Chemistry, p. 281. 2 Ibul. p. 288. 3 Ibid, and General Report of Scotland, vol. ii. p. 527- 4 Davy’s Agricultural Chemistry, p. 289. s Farmer's Magazine, vol. xvi.

Ouse, the Don, and other rivers which empty themselves into the great estuary of the Humber, are so loaded with mud, that if a cylindrical glass twelve or fifteen inches long be filled with them, there will presently be deposit¬ ed an inch or sometimes more of what is called warp. But where this matter comes from has been the subject of dispute; for the water of the Humber at its mouth is clear, and in the very driest seasons the warp is most plentiful. The improvement consists in nothing t more than letting in the tide at high water, to deposit the warp, and permitting it to run off again as the tide falls. The effect of this practice is to cover the surface with a new soil, which may be raised in the course of one sum¬ mer from 6 to 16 inches, so that it is immaterial what may be the nature of the original soil; and the whole sur¬ face is left quite level, whatever hollows there may have been before being now filled up. The operation begins usually in the month of July, and proceeds during the rest of the summer season. The expense is said not to exceed L.12 or L.15 the acre; and land has been known to rise in value by warping from L.5 to L.40 or L.50 per acre. This new soil is so rich that it will carry very large crops for several years after¬ wards without any manure; but it should be sown with clover, and left in that state for two years, before it is opened for corn: it will then bear any sort of crop suited to the quality of the soil. In this respect there is a con¬ siderable difference even upon the same field, the warp in some places being a strong loam, and in others light and friable. For a more particular description of this process, the reader is referred to the Agricultural Survey of the West Riding of Yorkshire. The Italian practice referred to is thus described by an intelligent tourist:— Colmata. “ In the Val di Chiana, fields that are too low are raised and fertilized by the process called Colmata, which is done in the following manner. The field is surrounded by an embankment to confine the water. The dyke of the rivulet is broken down so as to admit the muddy water of the high floods. The Chiana itself is too power¬ ful a body of water to be used for this purpose ; it is only the streams that flow into the Chiana that are used. This water is allowed to settle and deposit its mud upon the field. The water is then let off into the river at the lower end of the field, by a discharging course called scolo, and in French, canal d'ecoulement. The water-course which conducts the water from a river, either to a field for irrigation or to a mill, is called gara. In this manner a field will be raised five and a half, and sometimes seven and a half feet in ten years. If the dyke is broken down to the bottom, the field will be raised the same height in seven years; but then in this case gravel is also carried in along with the mud. In a field of 25 acres, which had been six years under the process of Colmata, in which the dyke was broken down to within three feet of the bottom, the process was seen to be so far advanced, that only an¬ other year was requisite for its completion. The floods in this instance had been much charged with soil. The water which comes off cultivated land completes the pro¬ cess sooner than that which comes off hill and woodland. Almost the whole of the Val di Chiana has been raised by the process of Colmata.” {Journey in Carniola, Italy, and France; by W. A. Cadell, Esq. F. R. S.) Sect. X. Farm Drains. Farm Though we propose to treat of the important subject of drains. drainage in a separate article, yet it seems proper here to notice such drains as are usually executed by farmers t cu| themselves, without the assistance of a professional man. rV These may be divided into such as are best suited to soilsM "V rather loose and incohesive, and such as are best adapted to alluvial clays or soils of a uniform and close texture. With regard to the first sort of drains, the practice istoOi ^ cut them in such a situation as to catch the spring beforesoi it oozes out of the subsoil and spreads itself over the sur¬ face. In common language, the line of the drain com¬ mences between the “ wet and the dry,” and is of such a depth as may be necessary to get down to the porous or sandy subsoil from which the spring emerges. In gene¬ ral from two and a half feet to three and a half feet may be a sufficient depth ; and where the spring is not found at the latter depth, tapping or boring may be resorted to. These drains are cut about the breadth of the spade at bottom, and opened no wider at the surface than is ne¬ cessary to give room to the labourer to work, which may be usually from fifteen to eighteen inches. The best ma¬ terial for filling them up with is small round stones, which are usually to be got from the surface of the land itself; but a variety of other materials are occasionally employ¬ ed, such as furze, broom, and even straw, in situations where stones cannot be readily procured. If there be reason to expect a constant current of water in the bot¬ tom of the drain, some care must be taken in laying the stones at the bottom, by forming a sort of arch, or by building up either side a few inches, and laying flat stones as a coping above, leaving a clear space for the stream below. But in most cases it is sufficient to select small round stones for the bottom, which are thrown in promis¬ cuously, the interstices, as in the case of gravel, allowing the water to percolate freely through them. When the drain has been filled up to within ten or twelve inches of the surface, the stones are covered with turf or sod, the grassy side undermost, and then the earth that had come out of the drain is thrown above until it comes to the level of the surface. It is obvious, that to insure the free working of these drains, they must never be disturbed by the plough, and therefore the covering of earth should be always somewhat deeper than the plough works. On alluvial or clayey soils not infested w ith springs, theO: ay evil is necessarily somewhat different, and requires a dif-so ferent remedy. Here the soil is of itself tenacious of moisture, and does not allow the rain water to pass freely through it. On such soils it may be thought that covered drains can be of little use; but long experience has proved their efficacy, and the practice has within these few years been introduced into Scotland from Essex and other parts of England. It is thus described in a com¬ munication to the Highland Society of Scotland, and our own observation can bear witness to the writer’s accuracy. “ The work is performed by means of three spades of J |e different sizes. The first may be a common spade of mo-11 derate breadth, with which the surface-clay may be taken off to the depth of eight or ten inches, or not quite so much if the clay be very strong. The breadth of the drain at top may be from a foot to fifteen inches, but it should never be less than a foot, as it is an advantage that the sides should have a considerable slope,—and the two sides should slope as equally as possible. Another workman follows the first, with a spade six inches broad at the top, and becoming narrower towards the point, where it should not exceed four inches. The length of the plate of this second spade should be fourteen inches, and with it a foot or fourteen inches in depth can easily be gained. A third workman, and he should be the most expert, succeeds the second, and his spade should be foui inches broad at the top, only two inches broad at the point, AGRICULTURE, ■ul- and fourteen or fifteen inches in length. With this spade a 13. good workman can take out at least fifteen inches of clay. sort of hoe or scoop, made of a plate of iron formed nearly into the shape of a half-cylinder, of two inches dia¬ meter and a foot or fourteen inches long, and fastened at an acute angle of perhaps 70° to a long wooden handle, is now employed to scrape out the bottom of the drain, and re¬ move any small pieces of clay that may have fallen into it. “ This completes the cutting of what is by the workmen called a three stamp drain. Where circumstances may render it necessary, they may be made of four, five, or more stamps. I would in no case, unless perhaps where the land is to remain permanently in sheep-pasture, and is free from moles, recommend their being made less than three feet deep; and I am inclined to think, that where levels will admit of it, it would almost always be more advantageous that the depth should be four feet. Where the field is in summer fallow at the time, six inches of depth can generally be gained by gathering the ridges pretty high, and taking as deep a water-furrow as pos¬ sible, with a wide-set plough. Three stamps or spits taken from the bottom of this water-furrow will give a depth of at least three feet and a half when the ridges are reduced to the proper shape, which is easily done in the course of the subsequent ploughings. In all cases I think it best to put a drain in every furrow, though some people put only one in every second furrow.” In filling these drains, turf matted with the roots of coarse grasses is considered the best material, though where this cannot be got, other articles, such as wood, peat, clay, and even straw, have been found to answer. “ The turfs should be cut into an oblong shape, about four inches and a half broad (some make them narrower a little at the grassy side than at the other, but this is not very easily done, and I believe not very material), and from three to five inches thick. They are generally made about fourteen inches long. The grassy side of the turf being turned undermost, they are put down into the drain, the work¬ man standing upon them after they are put in, and press¬ ing them down with his whole weight till they are firmly wedged between the sloping sides of the drain. The ends of the turfs being cut somewhat obliquely, they overlap each other a little; and by this means, although there is sufficient opening for the surface-water to get down, no¬ thing else can. The open space below the turf ought to be about five or six inches in depth, three inches wide at top, and one and a half or two inches at bottom. Some people prefer making the turf a little broader, and by that means leaving a larger space below, from the idea that it will be less likely to choke; but when the open space is much larger, the sides of the drain below the turf are probably more apt to give way for want of support. 4 The operation may now be completed by turning in as much earth, either with the spade or the plough, as to up the drain to the proper level.”—“ I must remark, tha,t the improvement has always appeared to me more striking in the first two or three crops than afterwards; and the reason, I apprehend, is, that although the drains remain perfectly clear, the clay above them becoming gradually more compact, the surface-water does not get down into them - • ” ~ - ■ -• ’ 307 first. so quickly after a few years as it did at p he price I now pay for cutting wedge-drains three eet deep, including the cutting of the turf and putting it > is 4d. per rood of 20 lineal feet; and I am at the ex¬ pense of carrying the turf from the place where it is cut, aymg it down close to the drains in a regular line, so a tie person employed by the contractor in putting it can easily reach it without coming out of the drain. “ The expense of draining per acre must, it is obvious, Agricul- depend on the breadth of the ridges. Where these are of ture. fifteen feet, the most common breadth in our carses itVw^v-Nk- will cost about L.2. 17s. per acre ; but in wedge-drained land, I think the ridges may be advantageously made eighteen or twenty feet broad, which will of course be at¬ tended with a proportionate reduction of the expense of draining.” {Prize Essays and Transactions of the High¬ land Society of Scotland, vol. vi.) With respect to currents of water so considerable as not to admit of covered drains, the drains must of course be left open; but in this case it may usually be practicable to carry the water, by means of covered drains, into the fence-ditches, instead of leaving them open in the middle of the field. It has been already observed that a ditch forms a part of the fence, wherever the white thorn or other live hedges are employed for that purpose. CHAP. II. OF LAND UNDER PERENNIAL HERBAGE, AND IN A STATE OF NATURE. There are few tracts of any extent throughout Great Natural Britain, if we except the shifting sands on some parts ofherbage. the coast, that do not bear plants of one kind or other; and having treated, in the preceding chapter, of crops raised by the labours of agriculture, it remains to consider those parts of our territory which nature has clothed with plants, the spontaneous products of soil and climate, and to mention the purposes to which these tracts are applied, and the improvements of which they are susceptible. In the earlier stages of society, the cerealia used for the food of man necessarily obtain the principal attention of the cultivator. Little or no labour is required to provide food for the few animals whose assistance he needs in his rude operations; and herds and flocks, which propagate around him without his care, find the means of subsistence in those extensive wilds on which his feeble exertions have not yet materially encroached. Though he is chiefly indebted to these animals, at this period, both for his food and clothing, agriculture must have made considerable progress before he attempts to supply their occasional wants by improving their pastures or cultivating plants expressly for their maintenance. Until the middle of the seventeenth century, neither roots nor herbage were cul¬ tivated for live stock in England, nor in Scotland till about a hundred years after. The only provision for their sub¬ sistence, during the long winters of our latitude, was na¬ tural herbage in the state of hay, commonly the produce of some marshy or humid soils, along with the straw of corn; and during summer, the natural pastures, too ge¬ nerally occupied in common, were thought to require and to admit of little or no improvement. It is not till the increase of population, and the exten- Progress sion of tillage to supply its wants, that, in consequence of towards successive encroachments on the range of the inferior cultivated animals, it becomes necessary at last to allot a part of the croPs' cultivated land itself for raising their food. In most coun¬ tries of Europe it is not found profitable, even at this day, to cultivate herbage and roots to any extent for {feeding cattle; and the same course of successive crops of corn, with which the earliest agriculturists everywhere began their labours, still prevails almost universally in the north of Europe; not because all the land is required for pro¬ ducing grain, but, on the contrary, because the demand of the population for grain is so limited, compared with the extent of the country, as to leave the far greater part in the possession of the inferior animals, which in this case 308 AGRICULTURE. can be brought to market at a much lower price than would replace the charges of feeding them on crops rais¬ ed by means of aration. Other causes than the scantiness of population have produced a similar effect, though in a much smaller de¬ gree, in Great Britain; and by far the larger part of our territory also is still appropriated to the maintenance of live stock. A great portion of it, indeed, is incapable of being cultivated with any advantage ; but meadows, pas¬ tures, and wastes, are spread over extensive tracts, that would yield cultivated crops in abundance, both for man and the inferior animals. Before concluding this article, we shall have occasion to notice what seem to be the causes of this state of things; but it is unquestionable that, in the present circumstances of the country, a great deal of the most fertile land is employed more profitably for its owners and occupiers, under perennial herbage, than it could be under our most approved courses of tillage. In what respect the interest of the nation is concerned in this arrangement, this is not the place to inquire. To give a concise view of the agricultural state of the land in Britain not subjected to aration, we shall offer some observations on Meadows, on Natural Pastures, and on Wastes, in separate sections. Sect. I. Meadows. By meadows, we understand all such land as is kept under grass chiefly for the sake of a hay crop, though oc¬ casionally, and at particular seasons of the year, it may be depastured by the domesticated animals ; and we usually include under this term the notion of a greater degree of moisture in the soil, than would be thought desirable either for permanent pasture or lands in tillage. Where hay is in great demand, as near large towns, and espe¬ cially if a good system of cropping be but little under¬ stood, a great deal of arable land, indeed, may be seen appropriated to hay crops ; but the most valuable meadows are such as are either naturally rather moist, or rendered so by means of irrigation. Very little As the alternate and convertible systems of husbandry, meadow in before explained, prevail throughout all the lowlands of Scotland. Scotland, there is little land that deserves the name of meadow; though it is sometimes applied to marshy spots, not worth improving for tillage, which yield a quantity of coarse herbage to be made into hay, and are called bog meadows. The only natural hay grounds of much value in Scotland are to be found in the sheep-walks of the southern counties, where one or two small inclo¬ sures near the farmer’s or shepherd’s dwelling-house are commonly reserved for producing hay to feed the flocks during a deep snow ; and as there is seldom much land in tillage in such places, the manure made from a few horses and cows is sometimes spread on the surface of these fields, though by no means according to any regular plan. To a very small extent, watered meadows have been tried in Scotland; but, from a general conviction of the superior advantages of cultivating herbage and roots on all soils that can be made to produce them, and probably also owing to the less fertilizing qualities of the waters, even meadows of this kind are not likely ever to become of ge¬ neral importance there. The remarks which we mean to offer on this subject must therefore be understood as ap¬ plicable to the practice of England only. Plants. The indigenous plants of which meadow-grass consists necessarily vary with the qualities of the soil. The most Agricul¬ ture. Greater part of Britain still allot¬ ted to live stock. Meadows. valuable are, the sweet-smelling vernal-grass (Anthoxm. a ihum odoratum); perennial ryegrass (Lolium perenne) ■ foxtail (Alopecurus pratensis); common meadow-grass^ (Poa trivialis and Poa pratensis) ; and soft meadow-grass (Holcus lanatus). The poas compose the greater part of the celebrated Orcheston meadows near Salisbury, and of the no less productive meadows near Edinburgh. The period at which stock is excluded from meadows, Ti in order that the grasses may rise for a hay crop, is dif-sh ferent, according to the nature of the soil in regard touP humidity, and the kind of stock with which the land isdm depastured. In some instances the cattle are removed in November, while the sheep are continued on the ground till February. {Middlesex Report, p. 224.) In other places the meadows are open to all kinds of stock from August to April {Id. p. 219), and to sheep even till May. {Lin¬ colnshire Report, p. 196.) In the judicious management of meadow lands, atten-M tion must be paid to prevent the stagnation of water andm< the growth of aquatic plants, and to extirpate fern, docks, thistles, and other weeds. Moss, in particular, often es¬ tablishes itself on such lands, to the great injury of the valuable grasses, and can with difficulty be removed, even by the application of calcareous manures. Ant and mole¬ hills also abound in meadows, and are too often so much neglected as to render a large portion of the surface near¬ ly unproductive. And in these, as in all other hay grounds, the preparatory operations for the scythe should always conclude with the use of a heavy roller. The most important particulars in the management of meadow lands are, their improvement by irrigation, and by the application of manure. Of Irrigation we shall treat in a separate article. With regard to the time at which manure should be applied, a great difference of opinion prevails among the farmers in England. In the county of Middlesex, where almost all the grass-lands are preserved for hay, the ma¬ nure is invariably laid on in October {Middlesex Report, p. 224), while the land is sufficiently dry to bear the driv¬ ing of loaded carts w ithout injury, and when the heat of the day is so moderated as not to exhale the volatile parts of the dung. Others prefer applying it immediately after the hay-time, from about the middle of July to the end of August, which is said to be the “ good old time1 and if that season be inconvenient, any time from the begin¬ ning of February to the beginning of April.2 It is, how¬ ever, too common a practice to carry out the manure during frosty weather, when, though the ground is not cut up by the carts, the fertilizing parts of the dung are dissipated and washed away by the snow and rains before they can penetrate the soil. “ There is scarcely any sort of manure that will not be useful when laid on the surface of grass-lands; but in ge¬ neral those of the more rich dung kinds will be the most suitable for the older sorts of sward-land, and dung in composition with fresh vegetable earthy substances the more useful in the new lays or grass-lands.”—“ In this district it is the practice of the best farmers to prefer the richest dung they can procure, and seldom to mix it with any sort of earthy material, as they find it to answer the best in regard to the quantity of produce, which is the principal object in view ; the cultivators depending chief¬ ly on the sale of their hay in the London markets.”—“ h is the practice to turn over the dung that is brought from London in a tolerable state of rottenness, once chopping it well down in the operation, so as to be in a middling ml. v. of a- 1 Com. to Board of Agriculture, vol. iv. p. 138. 2 Dickson’s Practical Agriculture, vol. ii. p. 915* AGRICULTURE. 1_ state of fineness when put upon the land. It is necessary, t e. however, that it should be in a more rotten and reduced state when applied in the spring, than when the autumn is chosen for that purpose.” (Dickson’s Practical Agricul¬ ture, vol. ii. p* 915.) Kxfi- Some very interesting experiments have been made men wjth different kinds of •’manure, for the purpose of ascer¬ taining their effects, both in regard to the quantity and qua¬ lity of the produce on different kinds of land. Fourteen lots, of half an acre of eight yards to the rod each, were thus manured, and the grass was made into hay, all as nearly alike as possible. The greatest weight of hay was taken from the lot manured with horse, cow, and butchers’ dung, all mixed together, of each about an equal quantity. It lay in that state about two months, and was then turn¬ ed over and allowed to lie eight or ten days more, after which it was put on the land before it had done ferment¬ ing, and spread immediately. And to ascertain the qua¬ lity of the produce of the different lots, a small handful from each was laid down on a dry, clean place, where there was little or no grass, and six horses were turned out to them, one after another. In selecting the lots, there seems to have been little difference of taste among the horses; and all of them agreed in rejecting two lots, one of which had been manured with blubber mixed with soil, and the other with soot,—in both instances laid on in the month of April preceding. {Lancashire Report, p. 130, et seq.) “ The proportion of manure that is necessary must in a great measure depend upon the circumstances of the land, and the facility of procuring it. In this district (near London), where the manure is of a very good and enriching quality, from its being produced in stables and other places where animals are highly fed, the quantity is usually from four or five to six or seven loads on the acre, such as are drawn by three or four horses in their return from town on taking up the hay.” (Dickson’s Practical Agriculture, vol. ii. p. 916.) Manure is laid on at intervals of time, more or less dis¬ tant, according to the same circumstances that determine the quantity of it. Though there are some instances of hay-grounds bearing fair crops every year during a length of years without any manure, or any advantage from pas¬ turage, except what the after-grass has afforded,1 yet in general manure must either be allowed every third or fourth year, or the land depastured one year and mown die other; “ or, what is better, depastured two years and mown the third.” {Noi'thumberland Report, p. 111.) A succession of hay crops, without manure or pasturage, on meadows not irrigated, is justly condemned by all judi- cious farmers, as a sure means of impoverishing the soil. mode of converting this herbage into hay, being somewhat different from that which has been described in regard to clovers and ryegrass, requires to be mention¬ ed here. The farmers of Middlesex, who supply the me¬ tropolis with hay, are understood to manage this depart¬ ment of rural economy in a very perfect manner; and a particular account of their practice is given in the Report oy Middleton, to which we refer. “ In the course of hay-making,” says this writer, “ the "•ass should, as much as possible, be protected both day and night against rain and dew, by cocking. Care should a so be taken to proportion the number of hay-makers to mt of the mowers, so that there may not be more grass d fi any ^me ^ian oan be managed according to le tlescribed process. This proportion is about twenty hay-makers (of which number twelve may be women) to Amicul four mowers : the latter are sometimes taken half a day ture. to assist the former. But in hot, windy, or very drying weather, a greater proportion of hay-makers will be re¬ quired than when the weather is cloudy and cool. “ If ^ particularly necessary to guard against spreading more hay than the number of hands can get into cock the same day, or before rain. In showery and uncertain weather the grass may sometimes be suffered to lie three, four, or even five days in swath. But before it has lain long enough for the under side of the swath to become yellow (which if suffered to lie long would be the case), particular care should be taken to turn the swaths with the heads of the rakes. In this state it will cure so much in about two days as only to require being tedded a few hours, when the weather is fine, previous to its being put together and carried. In this manner hay may be made and stacked at a small expense and of a good colour, but the tops and bottoms of the grass are insufficiently separated by it. “ There are no hay-stacks more neatly formed, or better secured, than those of Middlesex. At every va¬ cant time, while the stack is carrying up, the men are employed in pulling it with their hands into a proper shape; and about a week after it is finished, the whole of it is properly thatched, and then secured from receiving any damage from the wind, by means of a straw-rope ex¬ tended along the eaves, up the ends, and near the ridge. The ends of the thatch are afterwards cut evenly below the eves of the stack, just of sufficient length for the rain¬ water to drip quite clear of the hay. When the stack happens to be placed in a situation which may be suspect¬ ed of being too damp in the wunter, a trench of about six or eight inches deep is dug round, and nearly close to it, which serves to convey all the water from the spot, and renders it perfectly dry and secure.” {Middlesex Report, p. 238-241.) When the grass has risen again after the hay crop, it is After- usually depastured, as has been already mentioned when grass, treating of clovers: to mow a second time is considered a bad practice among the best hay farmers. {Middlesex Report, p. 249.) But it is the usage of some to leave the after-grass on the ground without being eaten till spring, when it is said to be preferable, for ewes and lambs, to turnips, cabbages, or any other species whatever of what is termed spring-feed. This mode of management, which is strongly recommended by Mr Young, and in some cases by Mr Marshall also, is unknown in the north, where, though it is in many cases found beneficial, with a view to an early spring growth, not to eat the pastures too close before winter, it would be attended with a much greater loss of herbage than any advantage in spring could com¬ pensate, to leave the after-growth of mown grounds un¬ touched till that season. There has never been found any deficiency of milk with ewes that are tolerably well sup¬ plied with turnips a little before and after they drop their lambs. The weight of the hay produced on meadows well ma¬ naged, being on an average about one ton and a half per acre, holds out little encouragement to retain good arable land in this condition ; and, unless near London and a few other large towns, pasturage would probably give a much more valuable return. In Lincolnshire, where there are some of the richest grazing lands in England, it is ob¬ served that all lands that will feed cattle should be mown as little as possible ; and nothing pays worse there than the 1 Marshall’s Review of Reports to the Board of Agriculture, p. 183, Western Department. 310 AGRICULTURE.

The pasture lands to be treated of here are, therefore, such as are retained permanently, or at least for an indefinite period, in this state, merely for the sake of the herbage they yield, and without any particular view to the amelioration of the lands for bearing crops of grain. In this general ap¬ plication of the word, permanent pastures include not only such land as might be cultivated by the plough, but also all those uplands to which tillage operations could not be extended with any prospect of remuneration, such as the far greater part of the hilly and mountainous sheep grounds throughout this kingdom. The nature of these pastures is, however, so different, and the expediency of retaining arable land in permanent pasture has been so keenly dis¬ cussed, that it will be proper to notice the two descrip¬ tions separately, under the general though not quite ac¬ curate appellations of feeding and hilly pastures. Under the former we may comprehend all old rich pastures that are capable of fattening cattle; and under the second, such as are adapted to rearing them only, or are more advantageously depastured by sheep. 1. Feeding-Pastures. Feeding- Of these thei*e is a great extent in most of the counties of pastures. England, but very few in Scotland, except near the houses of great proprietors; and much useless controversy has been carried on between the farmers of the two countries, about the comparative advantages of preserving such pas¬ tures, or of bringing them under a regular system of alter¬ nate or convertible husbandry. That much of this land in the south would be more productive, both to the pro¬ prietor and occupier, under a good course of cropping than under pasture, it is impossible to deny; but it is no less certain, that there are large tracts of rich grazing land, which, in the present state of the demand for the produce of grass-lands, and of the law of England with regard to tithes, cannot be employed more profitably for the parties concerned than in pasture. The interest which the Board of Agriculture has taken in this question, with a view to an abundant supply of corn for the wants of a rapidly increasing population, seems, therefore, not to have been well directed. Instead of devoting a large por¬ tion of their volumes to the instruction of farmers re¬ garding the best method of bringing grass-lands into til¬ lage, and restoring them again to meadow or pasture without deterioration, the first thing required was to at¬ tempt removing the almost insuperable obstruction of tithes, by proposing to the legislature an equitable plan of commutation. If some beneficial arrangement were adopted on this head, there is no reason to doubt that in¬ dividual interest would soon operate thewished-for change; and that all grass-lands capable of yielding more rent and profit under tillage than under pasture would be subject¬ ed to the plough as fast as the demands of the population might require. Different Except in regard to those necessary operations that opinions as have been already noticed under the former section,— inera na”e"suc^ as ^le exl’rPat*on °f weeds and noxious shrubs, clearing away ant and mole-hills, &c.—there are few points the inclosures,—and the propriety of eating the herbage close, or leaving it always in a rather abundant state,-—are all of them questions which it is- scarcely possible to de¬ cide in a satisfactory manner by the application of gene¬ ral rules. They can only be resolved, with any preten¬ sions to utility, "by a reference to the particular circum¬ stances of each case; for the practice of one district, in regard to these and other points, will be found quite in¬ applicable to others, where the soil and climate, and the purposes to which the pastures are applied, are materially different. It has been recommended to apply manure to grass¬ lands, even where, not being used as hay grounds, they afford no means of supply. (Dickson’s Practical Agri¬ culture, vol. ii. p. 953.) But, excepting the dung dropped by the pasturing animals, which should always be regu¬ larly spread from time to time, it may be laid down as a rule of pretty extensive application, that if grass-lands do not preserve their fertility under pasturage, it would be much better to bring them under tillage for a time, than to enrich them at the expense of land-carrying crops of Another practice, which is scarcely less objectionable, is that of stacking on the field, or carrying to be consumed there during winter the provender that ought to have furnished disposable manure for the use of the farm at large. It is to no purpose that such a wasteful practice is defended, on dry light soils, which are alleged to be thus benefited by the treading of the cattle. (Marshall’s Rural Economy of Yorkshire, vol. ii. p. 131.) During the frequent and heavy falls of rain and snow in winter, there is scarcely any land so dry as not to be injured by the treading of heavy cattle ; and were there any thing gained in this respect by this management, it would be much more than counterbalanced by the loss of a great part of the manure from the same cause. The able writer to whom we have just referred very properly disapproves of carting on manure in winter; and for the same rea¬ son,—namely, the loss of it which must necessarily be the consequence,—he ought to have objected to fodder¬ ing on the land, or teathing, at that season. The practice, however, is but too common in those districts, both in South and North Britain, where the knowledge of correct husbandry has made but little progress. It is equally ob¬ jectionable, whether the fodder be consumed on meadows where it grew, or on other grass-lands. The fodder should in almost every instance be eaten in houses or fold-yards, instead of the dung being dropped irregularly over the surface, or, as must be almost always the case, accumulat¬ ed in some spots sheltered by trees and hedges, to which the animals necessarily resort during the storms of winter. The time of opening pastures in spring must evidently c be earlier or later, according to the climate, and in thep same climate according to the season; and the state ofs] growth which it is desirable that the grass should attain before being stocked, must in some degree be determined by the condition and description of the animals to be em¬ ployed in consuming it,—whether they are only in a grow¬ ing state, or approaching to fatness,—whether milch cows or sheep, or a mixture of animals of different species. R conveys no very precise idea respecting these points, though the remark itself is just, to say that the herbage should not be allowed to rise so high as to permit the coarser plants to run to seed, and that it is bad manage¬ ment to suffer store stock to be turned upon a full bhe.

Some time in autumn, when In regard to the state of the growth of pastures when the ardent heat of the season is over, and when there is still time for a new growth before winter, may be most suitable for the land itself, and generally also for the grazier, his fat stock being then mostly disposed of, or carried to the after-grass of mown grounds. The sweeping Itatej rowtl hen ; ockes lock.i first stocked, some distinction should be made between new leys and old close swards. To prevent the destruc¬ tion of the young plants, whether of clovers or other herb¬ age, on the former description of pasture, which would with sheep, they should be allowed to rise higher than would be necessary in the case of old turf; and to secure their roots from the further injury of a hot summer, it is advisable not to feed them close in the early part of the season, and probably not at any time throughout the whole of the first or second season, if the land is to be continued in pasture. The roots of old and firm sward, on the other hand, are not in so much danger, either from close feed¬ ing or from the heats of summer; and they are in much less danger from the frosts and thaws of winter. Another circumstance almost equally indeterminate with the time of opening pastures, is the stock which be the consequence of stocking them too early, especially of pastures with the scythe may be employed as a sub- ”’:+k ^ stitute for this close feeding; the waste and labour of which, however, though they be but trifling, it does not seem necessary to incur on rich grazing lands under cor¬ rect management.

Mr Marshall has given a full ac¬ count of the method of forming drinking pools in York¬ shire, but our limits oblige us to refer the reader to his work. _ _ . Trans- A practice has been introduced into Norfolk within planting these few years, the object of which is to obtain a rich *urk turf, with all the valuable qualities of old pasture, much sooner than from seeds alone. This is called trans¬ planting turf, or inoculating land with grass. A field of good old grass-land is stripped of part of its turf, which is cut into pieces of about three inches square, and placed in its new situation, about six inches apart, on land previ¬ ously prepared to receive it. In this way one acre of turf will plant nine acres; but it is only a part of the old pas¬ ture that is taken off, and this is done in such a manner as not materially to injure it. After being thus planted, the roots are pressed down by means of heavy rollers, which cause them to spread along the ground instead of rising up in tufts ; and in a summer or two, during which this transplanted pasture should be very lightly if at all fed upon, the grasses shed their seeds and fill up the in¬ terstices, the whole being then formed into a compact and uniform turf. (Blaikie on the Conversion of Arable Land into Pasture.) Later writers, particularly Sinclair, the au¬ thor of Hortus Gramineus Woburnensis, think this practice has excited notice only by its novelty, and that it never can become of extensive utility. their continuance to neglect or mismanagement, and that any exertions of human industry can ever render the greater part of them, including all the mountainous tracts'-- of Great Britain, more valuable than they are at present, without a much greater expenditure of capital than, under almost any circumstances, they could possibly return. Yet as this vague general term has been established by use, we shall bring together, in the following section, a few observations on the present condition of that part of our territory which is still almost in a state of nature, and the improvements of which it is susceptible. 2. Hilly Pastures. Sect. III. Wastes. hi. re. A, idem. as ti im. Hill pas- These include such low hills as produce fine short herb- tures. age, and are with much advantage kept constantly in pas¬ ture, though they are not altogether inaccesible to the plough; as well as such tracts as, from their acclivity and elevation, must necessarily be exclusively appropriated to live stock. The former description of grass-lands, though different from the feeding pastures, of which we have just treated, in respect of their being less convenient for til¬ lage management, are nevertheless in other circumstances so nearly similar as not to require any separate discus¬ sion. These low hills are for the most part occupied with sheep, a very few cattle being sometimes depastured to¬ wards their bases ; and they frequently comprise herbage sufficiently rich for fattening sheep, together with coarser pastures for breeding and rearing them. In many instances, a small part of such tracts is cultivated chiefly for pro¬ viding green crops for the sheep in winter; but corn is quite a subordinate object, and extensive aration is seldom attempted, except for the purpose of laying down the land to grass in an improved condition. Improper- The more elevated pastures, from which the plough is Iv called altogether excluded, have been commonly classed among wastes. waste lands,—even such of them as bear herbage by no means of inconsiderable value,—as well as heaths and moors, with patches of which the green pastures are often chequered. The general term ivastes is therefore a very indefinite expression, and indeed is not unfrequently made to comprehend all that extensive division of our territory that neither produces corn nor rich herbage. Yet it is on such tracts that by far the greater part of our butcher-meat and wool is grown, and not a little of tire former fully prepared for the market. Foreigners and superficial readers at home must accordingly be greatly mistaken if they imagine that what are called wastes by the Board of Agriculture, and other' writers on rural economy, are really altogether unproductive; and it would be a still grosser error to believe that these wastes owe That part of Britain which is still in a state of waste p ^ might be treated of under a number of heads, correspond-tV L ing to the various causes of its infertility. Land is com¬ paratively unproductive, owing, Is#, to the surface being covered with stones, or occupied with worthless shrubs and other plants; 2dly, to the superabundance of wa¬ ter, as in the case of mosses and marshes; Mly, to an original defect in the soil, as in loose sands, moors, and compact sterile clays, sometimes called till; Uhly, to the elevation and ruggedness of the surface, and the ungenial character of the climate, as in our mountainous districts; bthly, to the previous exhaustion of the vegetable matter of the soil by injudicious cropping; and, bthly, to the mode of tenure and occupancy, as in commons. It is matter of regret that the subject of wastes has note yet been treated in that distinct and scientific mannerh which its importance deserves. It would be advisable to11 have it ascertained what portion of these divisions, or of1" others under which our wastes may be arranged, is ca-11 pable of improvement, and how far such improvement is eligible, on a fair estimate of the cost, and the probable increase of produce. It should also be considered, as far as precision is attainable on such points, how much farther a proprietor might advantageously proceed in the expen¬ diture of capital, than one who is merely a temporary oc¬ cupier. For it is evident that an improvement will be sufficiently profitable to the former if he draws for his outlay 4 or 5 per cent, yearly; whereas a tenant, holding on a lease of 20 years, must have an annuity for that pe¬ riod of at least three times the amount, in order that his capital may be returned, with the ordinary profits of trade, before its expiration. The delusive prospects of profit from the improvement of wastes, held out by speculative men, have an unhappy tendency to produce disappointment in rash and sanguine adventurers, and ultimately to discourage such attempts as, with judicious attention to economy, would in all pro¬ bability be attended with great success. Those who are conversant with the publications that have lately appeared on this subject, must be aware with what caution the al¬ leged results of most of these writers ought to be exa¬ mined, and how different has been the experience or those who have ventured to put their schemes in practice, from what they had been led to anticipate. There are few soils, however, so unfertile, and few tracts of any extent so destitute of soil, as not to be sus¬ ceptible of profitable improvement, if the climate be not altogether hostile to vegetation, or the surface so steep or so rugged as not to admit of any other operations than such as must be executed by manual labour. With this exception, and the exception probably of what is callec flow moss,—that innabilis unda, on which there is reason to fear much capital has been employed to little purpose,— wastes are certainly capable of considerable improvemen ■ by surface or underdraining; by top-dressing with calca- AGRICULTURE. r, ,1- reous manures; by paring and burning as a preparation u . for tillage; by trenching, irrigation, and embankment. We shall offer a few remarks on this subject, in the or¬ der first above mentioned. Lanro- 1. When the surface of ground is much covered with vcrevithstones, it is material to consider not only the expense item which will attend the clearing of it, but whether the soil and climate be such as to remunerate the cultivator after it has been brought into a state of tillage, and to what purpose the stones themselves may be applied. When the stones that project from the surface are a part of the rock continued beneath the soil, it may be doubted whe¬ ther, instead of incurring the expense of working away the rock to such a depth as would allow the plough to pass over it, it may not be advisable to let the land remain in pasture, and improve it by top-dressings. Very large blocks of stone are cleared away by means of gunpowder; but if this is not necessary, they are raised by levers, and rolled upon a sledge, or by the use of a block and tackle attached to a triangle. In the latter case, a hole is bored into the stone, and an iron bolt with an eye driven into it; and this, though apparently inca¬ pable of bearing any great weight, serves to raise the stone in a perpendicular direction, until it can be deposited upon a cart or sledge placed below it, to be carried off the field. As soon as the stones are removed, the holes must of course be filled up, and the surface rendered tolerably level. Trer ing.The best method of doing this is by trenching, which an¬ swers the further purpose of deepening the soil, and remov¬ ing any remaining obstacle within the reach of the plough. “ The greater part of the land in the vicinity of Aber¬ deen,” says the author of the Report of that county, “ has, from the most barren and unproductive state, been tho¬ roughly improved by trenching. Not less than 3000 acres have been trenched within three miles of Aberdeen; and in all places of the county considerable additions have been made to the arable, by trenching the barren lands.” “ It is practised in barren land, which abounds in stones of different dimensions, sometimes, where the soil is dry, and in other cases, where it is wet, united with draining: it is practised when the object is to deepen the soil, or to mix a portion of the subsoil along with it: it is practised when the subsoil is tilly or very tenacious, as well as when that next the surface is unproductive, moory, or exhaust¬ ed by overcropping: and, lastly, it is practised when the land is foul, and when stronger or cleaner soil can be brought up to the surface. “ The expense indeed could not have been borne in many cases, if the first crop (for so it may be called, as it covered the whole soil) that was raised by the spade and mattock had not produced from L.30 to L.50 per acre. Ibis was a crop of granite stones, which was sold for paving the streets of London. But, after all, the ground that was thus gained to the community would not have been able to recompense the cultivator, if a mixture of the spade and plough husbandry had not been introduced, the rent of the land in the immediate vicinity of Aber¬ deen is extremely^ high, being now, on a lease for years, >om L.5 to L.10 per acre, and in a few cases not less than L.18; nay, when let for a single crop, sometimes as mgh as L.20. Yet all this is necessary to remunerate the improver, who trenched, dunged, limed, and cultivated us thin soil, which must be frequently manured. It would 'a\ e yielded too little produce, if tilled only by the plough ; and would have been cultivated at too great an expense, u the soil had been constantly digged by the spade. A medium between these two, viz. either the alternate use 1 1 ie plough and spade, or at least a mixture of plough VOL.

In the case of mosses and marshes, the first thing igMossesand to get rid of the superabundance of water, by opening main drain, into which such smaller ones as may be ne¬ cessary will discharge themselves. On the subject of improving moss land a great deal has been written within these few years, and many experiments made with very different results. In favourable circumstances, if the ope¬ ration is carefully and economically conducted, there can be no doubt that land of this description may be improved with ultimate benefit to the undertaker. But the great object ought to be, not (at least for some years at first) to convert the land into tillage, but merely to render it productive in the state of meadow or pasture. With this view, the first operation after draining should be to get rid of the heath and coarse herbage on the surface, by burning, levelling it where necessary at the same time, and then to top-dress with calcareous matter, either by itself or mixed up in compost with earth and other sub¬ stances, as a preparation for grass-seeds. If it be neces¬ sary to turn over the whole surface, this in many cases may be done as cheaply by the spade as by the plough, and to much better purpose. Timothy (jpbileum pratense) will be found one of the most valuable grasses on such a soil; but if the surface be sufficiently saturated with cal¬ careous matter, and not too wet, clovers, particularly white clover, and the grasses usually sown upon arable land, may be used with advantage. The after-management must of course depend upon circumstances. Frequent rolling must always be of use in compressing a soil which is naturally spongy; thus preventing the roots of the plants from being thrown out of the ground: and we should think that in general it must be better to retain such land for some years in the state of meadow, top-dressing it oc¬ casionally, than even in pasturage. Among the various attempts that have been made upon a large scale to reclaim moss land, we shall mention two that seem worthy of particular notice. The first cannot be considered as an improvement ofFloating the mossy soil itself. On the contrary, the improvement0^ nK)SS- consists in getting rid of it altogether. The practice may be shortly described as follows:— “ A stream of water is carried first upon the spongy upper stratum of moss, which is by this means conveyed away to the neighbouring frith or arm of the sea, the light moss being thrown into a ditch, made as the temporary bed of this artificial rivulet. The upper part, or spongy moss, is thus carried off by successive ditches, to the ex¬ tent of 30 or 40 yards broad; then a second deeper ditch is cut into the clay or bottom of the flat stratum of the heavy moss, and a number of parallel ditches are made for admitting the rivulet, into which the remaining moss is thrown, till nearly the whole is carried off, excepting a thin stratum, consisting partly of black peat-earth, and partly of decayed wood found in the moss, which is burnt for manure to the carse soil about to be cultivated. Much ingenuity has been shown in constructing machinery to supply water for removing the moss, previous to the im¬ provement of the carse or rich soil below. For some years after being thus cleared both of peat-moss and the remains of wood, successive crops of oats were formerly too often repeated; but this was found to be injurious, and a more regular mode of cropping is now introduced. “ In 1766, the late Lord Kames became proprietor of Kincardine the estate of Blair-Drummond, in the county of Perth,moss- where he resolved to carry on with spirit this mode of improvement on the moss of Kincardine. After trying 314 AGRICULTURE. Agricul- several experiments, he at last adopted the plan of giving ture. profitable leases to small occupiers of land, to induce them to remove the moss; and before his death in 1782, no less a number than 336 acres were cleared of moss, and brought into cultivation. His son and successor pursuing the same plan, got 440 acres more let in three years, to which additions were made periodically. In 1792 the population had increased to 764 souls, who cultivated 444 acres. By a survey in 1805, 577 acres were cleared, in¬ cluding 12 acres occupied by roads. In 1814 considerably above 800 acres were cleared, and the population amount¬ ed to upwards of 900 souls. “ Thus an extensive tract of country, where formerly only a few snipes and muirfowl could find subsistence, has been converted, as if by magic, into a rich and fertile carse of alluvial soil, worth from L.3 to L.5 per acre. ’ Mr lios- The other instance is that of the improvement of Chat coe’s im- moss in the county of Lancaster, by Mr Roscoe of Liver- prove- p00i. The length of this moss is about six miles, its merits on greatest breadth about three miles, and its depth may be Chat moss-estimated at from 10 to upwards of 30 feet. It is entirely composed of the substance well known by the name of peat, being an aggregate of vegetable matter, disorganized and inert, but preserved by certain causes from putrefac¬ tion. On the surface it is light and fibrous, but becomes more dense below. On cutting to a considerable depth, it is found to be black, compact, and heavy, and in many respects resembling coal. There is not throughout the whole moss the least intermixture of sand, gravel, or other material, the entire substance being a pure vegetable. It is now upwards of 20 years since Mr Iloscoe, in company with Mr Wakefield, began to improve Trafford moss, a tract of 300 acres, lying two miles east of Chat moss; and his operations on it seem to have been so suc¬ cessful as to encourage him to proceed with Chat moss. But in the improvement of the latter, he found it unne¬ cessary to incur so heavy an expense for drainage. From observing that, where the moss had been dug for peat, the water had drawn towards it from a distance of 50 to 100 yards, he conceived that if each drain had to draw the water only 25 yards, they would, within a reasonable time, undoubtedly answer the purpose. The whole of the moss was therefore laid out on the following plan. Drainage. “ I first carried a main road,” says Mr Roscoe, in a re¬ cent communication to the Board of Agriculture, “ nearly from east to west, through the whole extent of my por¬ tion of the moss. This road is about three miles long and 36 feet wide. It is bounded on each side by a main drain, seven feet wide and six feet deep, from which the water is conveyed, by a considerable fall, to the river. From these two main drains other drains diverge, at 50 yards distance from each other, and extend from each side of the road to the utmost limits of the moss. Thus each field contains 50 yards in front to the road, and is of an indefinite length, according as the boundary of the moss varies. These field-drains are four feet wide at the top, one foot at the bottom, and four feet and a half deep. They are kept carefully open, and, as far as my experience hi¬ therto goes, I believe they will sufficiently drain the moss, without having recourse to underdraining, which I have never made use of at Chat moss, except in a very few in¬ stances, where, from the lowness of the surface, the water could not readily be gotten oft’ without open channels, which might obstruct the plough.” Cultiva- The cultivation of the moss then proceeds in the fol- tion. lowing manner. “ After setting fire to the heath and herbage on the moss, and burning it down as far as prac¬ ticable, I plough a thin sod or furrow with a very sharp horse-plough, which I burn in small heaps, and dissipate; considering it of little use but to destroy the tough sods of the Eriophora, Nardus stricla, and other plants, whose matted roots are almost imperishable. The moss being^ thus brought to a tolerably dry and level surface, I then plough it in a regular furrow six inches deep; and as soon as possible after it is thus turned up, I set upon it the ne¬ cessary quantity of marl, not less than 200 cubic yards to the acre. As the marl begins to crumble and fall with} the sun or frost, it is spread over the land with consider¬ able exactness; after which I put in a crop as early as possible, sometimes by the plough, and at others with the horse-scuffle or scarifier, according to the nature of the crop; adding, for the first crop, a quantity of manure, which I bring down the navigable river Irwell to the bor¬ ders of the moss, setting on about 20 tons to the acre. Moss land thus treated may not only be advantageously cropped the first year with green crops, as potatoes, tur¬ nips, &c. but with any kind of grain; and as wheat has of late paid better to the farmer than any other, I have hitherto chiefly relied upon it, as my first crop, for reim¬ bursing the expense.” The expense of the several ploughings, with the burn-Ii ing, sowing, and harrowing, and of the marl and manure,111 but exclusive of the seed, and also of the previous drain-1* age and general charges, amounts to L.18. 5s. per acre; and in 1812, on one piece of land thus improved, Mr Roscoe had 20 bushels of wheat, then worth a guinea per bushel, and on another piece 18 bushels; but these were the best crops upon the moss. “ Both lime and marl are generally to be found within a reasonable distance ; and the preference given to either of them will much depend upon the facility of obtaining it. The quantity of lime necessary for the purpose is so small in proportion to that of marl, that, where the dis¬ tance is great, and the carriage high, it is more advisable to make use of it; but where marl is upon the spot, or can be obtained in sufficient quantity at a reasonable ex¬ pense, it appears to be preferable.” Mr Roscoe is tho¬ roughly convinced, after a great many different trials, that all temporizing expedients are fallacious ; and that “ the best method of improving moss land is by the application of a calcareous substance, in a sufficient quantity to convert the moss into a soil, and by the occasional use of animal or other extraneous manures, such as the course of cultivation and the nature of the crops may be found to require.” There seems to be little more that is peculiar to himself in Mr Roscoe’s operations and course of cropping, except his contrivance for setting on the marl. It would not be practicable, he observes, to effect the marling at so cheap a rate (L.10 per acre), were it not for the assistance of an iron road or railway laid upon boards or sleepers, and] movable at pleasure. Along this road the marl is con¬ veyed in waggons with small iron wheels, each drawn by one man. These waggons, by taking out a pin, turn their lading out on either side : they carry about 15 cwts. each, being as much as could heretofore be conveyed over the moss by a cart with a driver and two horses. In the month of November 1805, Mr Roscoe began the ] drainage by cutting out the main drains on each side oL the road, throwing out the moss from the drains into the1; middle of the road. In 1807 the smaller drains, at 50^ yards distance from each other, were begun, and about 1000 acres laid out in the manner already mentioned, hi 1808 part of the moss was sufficiently consolidated to be worked with horses in pattens: this year a farm-house, with out-buildings, cottages, &c. was erected, and man was set upon the land prepared for that purpose. About 20 acres were cropped with turnips and potatoes m 1809; and in the year following, upwards of 80 acres, o 'Kill. irv. VA. ■;nse ire. way. tssi Ros- inl¬ e¬ ts. AGRICULTURE. A?;"1- tn- Imp:^ dow.. which 20 were wheat. In 1811 Mr Roscoe had 100 acres in crop, chiefly in wheat; and in 1812 marl and street vX ^manure were applied in the quantities specified above. The crops were wheat and beans, which much surpassed those of any preceding year. “ In the course of the pre¬ sent year (1813) I shall have brought into cultivation about 160 acres, which will be cropped with wheat, oats, potatoes, and beans. A tract of 30 acres of clover ap¬ pears to be very promising.” The depreciation of agricultural produce in 1815, and the difficulty of combining a regular course of cropping [nto lea- w|th the bringing in of additional waste land, induced Mr Roscoe to lay down the whole of the improved part of Chat moss into meadow land. So long as land of this description continues productive in the state of meadow or pasture, it does not appear advisable to attempt any course of cropping whatever; and to lay it down for either of these purposes ought perhaps to form the chief induce¬ ment to its improvement. 3. A third cause of sterility is found in the natural tex¬ ture of the soil, as in loose sands and coarse impermeable clays. Moving or blowing sands occur on the sea-coast of many parts of Scotland, and are not only worthless themselves, but frequently inflict serious injury on the lands within their reach, over which the sand spreads it¬ self. This is a matter to which the Highland Society of Scotland have very properly turned their attention ; and we shall extract from their communications some account of an attempt that has been recently made to fix these sands, and to render them in some measure productive. The experiment to which we allude was made in 1819 315 Soils'a hardx- ture: Blov’g sand; Exp-. ) and 1820, on a farm in the parish of Harris, and county of ' “ k Invprnps's. h\r thp nrnnriptnr. Alpvnnrlpr XT IVTnplpprl then Inverness, by the proprietor, Alexander N. Macleod, Esq., “ who has completely succeeded in reclaiming and bringing into useful permanent pasture above 100 Scotch acres of useless blowing sand, by planting in it sea-bent (Arundo arenaria), known in the Hebrides by the name of bent-grass, and sowing rape-seed on it in a small pro¬ portion. The rape-seed requiring to be covered with sea-weed or some other manure immediately after sowing, is not considered so beneficial as the grass, as this requires no manure, or any other cultivation or top-dressing what¬ ever, after being properly planted. “ The operations commenced upon the above farm in the month of September 1819, by cutting the Arundo arenaria or bent-grass about two inches below the surface, with a small thin-edged spade with a short handle, which a man can use in his right hand, at the same time taking hold of the grass in his left; other persons carrying it to tlie blowing sand, to be planted in a hole, or rather a cut made in the sand, about eight or nine inches deep (and deeper where the sand is very open and much exposed), by a large narrow-pointed spade. A handful of Arundo arenaria or bent-grass was put into each of these cuts, which wrere about twelve inches distant, more or less ac¬ cording to the exposure of the situation. When properly fixed in the blowing sand, the roots begin to grow, and spread under the surface, in the course of a month after planting. “ When Mr Macleod commenced the operations in re¬ claiming the tract of ground alluded to, it was altogether covered with blowing sand in winter and spring, and nearly so m summer. A great part of it consisted of high banks ot sand, which did not produce grass or verdure of anv kind whatever. " The Arundo arenaria or bent-grass is relished by cattle in summer, but it is of greater value by preserv¬ ing it on the ground for wintering cattle. It would be in¬ judicious to cut it, because it will stand the winter better than any other grass, and is seldom covered with snow. Agricul- Neither wind, rain, nor frost will destroy it; but the old ture- grass naturally decays towards the latter end of spring and the beginning of summer, as the new crop grows. “ White and red clover will grow spontaneously among this grass in the course of a few years, provided it is well secured. It will produce seed in some instances within twelve months after planting; but the seed does not, on high exposed situations, come to the maturity that seed requires for sowing. On this account, to propagate this grass from the root is considered preferable to sowing. “ The Arundo arenaria or bent-grass operations should not commence in any season earlier than about the 20th October, and should be given up about the beginning of March, as this planting thrives much better in the wet season.” The other descriptions of soil, which owing to their tex- Coarse ture are of little value in their natural state, are close, c^ys- compact clays, imbedded with small stones, and incumbent upon subsoils which do not allow the water to escape. Such land is in general covered with stunted heath and other coarse plants, and to the other causes of its infer¬ tility is often added a bad climate. The object in this case, as in the former, should generally be to obtain better herbage, rather than to convert it into arable land. One of the most common and effectual practices in im-Paring and proving this description of land is paring and burning; a burning, practice which, in the case of old swards matted with the roots of coarse herbage and heath, is acknowledged, both by scientific and practical writers, to be highly advantage¬ ous as the next step to be taken after drainage. “ The process of burning,” says Sir Humphry Davy, “ renders the soil less compact, less tenacious and retentive of moisture; and, properly applied, may convert a matter that was stiff, damp, and in consequence cold, into one powdery, dry, and warm, and much more proper as a bed for vegetable life. “ The great objection made by speculative chemists to paring and burning is, that it destroys vegetable and ani¬ mal matter, or the manure in the soil; but in cases in which the texture of its earthy ingredients is permanently improved, there is more than a compensation for this tem¬ porary disadvantage. And in some soils, where there is an excess of inert vegetable matter, the destruction of it must be beneficial; and the carbonaceous matter remain¬ ing in the ashes may be more useful to the crop than the vegetable fibre from which it was produced. “ Many obscure causes have been referred to for the purpose of explaining the effects of paring and burning; but I believe they may be referred entirely to the dimi¬ nution of the coherence and tenacity of clays, and to the destruction of inert and useless vegetable matter, and its conversion into a manure. “ All soils that contain too much dead vegetable fibre, For what and which consequently lose from one-third to one-halflands pro¬ of their weight by incineration, and all such as contain their earthy constituents in an impalpable state of divi¬ sion, i. e. the stiff clays and marls, are improved by burn¬ ing ; but in coarse sands, or rich soils containing a just mixture of the earths, and in all cases in which the texture is already sufficiently loose, or the organizable matter suffi¬ ciently soluble, the process of torrefaction cannot be useful. “ All poor silicious sands must be injured by it; and practice is found to accord with theory. Mr Young, in his Essay on manures, states, ‘ that he found burning in¬ jure sand and the operation is never performed by good agriculturists upon silicious sandy soils, after they have once been brought into cultivation.” {Agricultural Che¬ mistry, p. 346.) 316 AGRICULTURE. Agricul- Some eminent cultivators, however, prefer using the We. plough at the very first. They begin with a wide, shallow furrow, laying over the surface as flat as possible ; and in that state it remains to rot for fifteen or eighteen months. It is then cross-pl°uWe(^’ usually about midsummer, and well harrowed; dressed with lime, ridged up, and sown with rye or oats the following spring. As soon as the crop is removed, it is ploughed for turnips, to which dung is ap¬ plied ; and the turnips being eaten on the ground by sheep, it is laid to grass the year after, the seeds being sown along with oats or barley. This mode of management, however, can only be adopt¬ ed on lands of rather a loose texture, suited to turnip. On more compact soils, we should think paring and burning, followed by top-dressings of lime and compost, a prefer¬ able practice. But if it be thought expedient to turn over the turf or sod with the plough, a great number of plough- ings and harrowings must be required to destroy the roots and pulverize the soil sufficiently; and two summers at least will be necessary to complete the operation. When it is thus brought into a state to be sown with grass-seeds, lime should be freely applied after the last ploughing, and well harrowed in ; and then the grass-seeds sown with or without a corn crop. Wherever the object is pasture, a comparatively small quantity of lime will produce the desired effect, if it be kept on the surface instead of being turned down by the plough. It is unnecessary to mention, that on soils of this description, tenacious of moisture, open trenches will be necessary, to prevent any water from stagnating, the furrows also being made so deep as to draw off and discharge any excess of moisture in the soil itself. This kind of land is evidently better suited to pasturage than to meadow, and the pasture may be kept from deterioration by repeated top-dressings. Mountain- 4. Much of our mountainous districts is necessarily ous tracts, left in a comparatively unproductive state, from the ele¬ vation and ruggedness of the surface, and ungenial cha¬ racter of the climate ; but such tracts present so great a variety in their circumstances, that it would be idle to at¬ tempt laying down any rules of general application. The leading improvement, we conceive, must be in carrying off the surface-water in open drains, and providing shelter by means of plantations. Land ren- 5. A soil not naturally unproductive has in many cases dered bar- been rendered sterile, at least for a time, by injudicious ren by management. When lime and other calcareous manures cromdno- were first applied to fresh soils, the corn crops produced ” were often so valuable as to lead to their repetition year after year, without the intervention of ameliorating crops or the application of manures. We have known three successive crops of wheat taken from the same land, and of corn altogether not less than ten crops in as many years. Under this management the soil could not fail to be reduced to a state of barrenness and waste, of which there are still too many instances in many parts of Scot¬ land. The appropriate remedy here is the use of enrich¬ ing manures, and after a time lime or other calcareous matters may be added. Such land has not only been robbed of its nutritive powers, but the very texture of the soil itself has experienced an unfavourable change. A few years’ pasturage must always be useful on land that has undergone so severe a course of tillage. Commons 6. Much of the commons and common lands through- and com- out the country may be considered as retained in a state mon fields. 0f comparative waste, by reason of their tenure and mode of occupancy. In Scotland there is now very little land in this state, the law affording a ready means of dividing A it, with a few exceptions, among the proprietors or oc¬ cupants, according to their respective rights and interests> It is otherwise, however, in England, where a special act of parliament seems to be necessary in almost every in. stance ; and though much has been done there in the way of allocating and improving such land under the authority of inclosure acts, much still remains to be done. But the improvement of such land is not so much an agricul¬ tural as a political question. When once it is brought into the state of private property, the methods to be adopted for rendering it more productive will necessarily depend upon the nature of the soil and other circumstances. nil. ■e. CHAP. III. LIVE STOCK. In the observations which we have to offer on this grand department of husbandry, which in some quarters of the island enjoys a decided preference over tillage, we shall treat, 1. Of Horses; 2. Of Cattle ; 3. Of Sheep; 4. Of Swine ; and, 5. Of Miscellaneous Stock. Sect. I. Horses. The form of a horse peculiarly adapted to the labours ofll agriculture, has been well described by a writer of great ex¬ perience, in the following words:—• “ His head should be as small as the proportion of theF animal will admit; his nostrils expanded, and muzzle fine; his eyes cheerful and prominent; his ears small, upright, and placed near together ; his neck, rising out from be¬ tween his shoulders with an easy tapering curve, must join gracefully to the head; his shoulders, being well thrown back, must also go into his neck (at what is called the points) unperceived, which, perhaps, facilitates the going much more than the narrow shoulder ; the arm or fore thigh should be muscular, and, tapering from the shoulder, meet with a fine, straight, sinewy, bony leg; the hoof circular, and wide at the heel; his chest deep, and full at the girth ; his loin or fillets broad and straight, and body round ; his hips or hooks by no means wide, but quarters long, and tail set on so as to be nearly in the same right line as his back; his thighs strong and mus¬ cular ; his legs clean and fine-boned; his leg-bones not round, but what is called lathy or flat.” (Gulley on Live Stock, p. 21.) 1. Breeds. 1. The black cart-horse, bred in the midland counties! of England (see Plate XII.), is better suited for drays and waggons than for the common operations of a farm. The present system of farming requires horses of more mettle and activity, better adapted for travelling, and more cap¬ able of enduring fatigue, than those heavy, sluggish ani¬ mals. This variety is understood to have been formed, or at least brought to its present state, by means oi stallions and mares imported from the Low Countries; though there appears to be some difference in the accounts that have been preserved, in regard to the places whence they were brought, and the persons who introduced them. “ The breed of grey rats,” says Mr Marshall, “ with which this island has of late years been overrun, is not a greater pest in it than the breed of black fen horses; at least while cattle remain scarce, as they are at present, anu ks. 1 See Gulley on Live Stock, p. 32 ; and Marshall’s Economy of the Midland Counties, vol. i. p. 30(>.

Mares worked. siduity as that which has of late years been bestowed on cattle and sheep, while the breeding of saddle-horses, hun¬ ters, and coach-horses, is almost entirely neglected ; is left almost wholly to chance, even in Yorkshire,—I mean as to females. A breeder here would not give five guineas for the best brood-mare in the kingdom, unless she could draw or carry him occasionally to market, nor a guinea extraordinary for one which could do both. He would sooner breed from a rip which he happens to have upon his premises, though not worth a month s keep. But how absurd ! The price of the leap, the keep of the mare, and the care and keep of her progeny, from the time they drop to the time of sale, are the same, whether they be from ten to fifteen, or from forty to fifty pounds each. (Marshall’s Economy of Yorkshire, vol. ii. p. 166.) In those districts where the breeding of horses is car¬ ried on upon a large scale, and upon a regular plan, the rearing of stallions forms in some degree a separate branch, and is confined, as in the case of bulls and rams, to a few eminent breeders. These stallions, which are shown at the different towns in the vicinity,—sometimes sent to be exhibited at a considerable distance,—are let out for the whole season, or sold to stallion-men, or kept by the breeder himself, for covering such mares as may be offer¬ ed, at a certain price per head ; and this varies according to the estimation in which the horse is held, and some¬ times according as the mare has more or less of what is called blood. For farm-mares, the charge for covering by a stallion of the same kind is commonly about a guinea, with half-a-crown to the groom ; and it is a common prac¬ tice in the north to agree for a lower rate if the mare does not prove with foal; sometimes nothing more is paid in that case than the allowance to the groom. The age at which the animals should be allowed to copulate is not determined by uniform practice, and is made to depend in some measure on the degree of ma¬ turity, which, in animals of the same species, is more or less early, according to breed and feeding. Yet it would seem in general to be an improper practice to allow ani¬ mals to propagate while they are themselves in a raw, un¬ formed state, and require all the nutriment which their food affords, for raising them to the ordinary size of the variety to which they belong. It may, therefore, be sel¬ dom advisable to employ the stallion till he is about three years old, or the mare till she is a year older. But the greater number of mares kept for breeding are much older than this, and are, in many cases, not allowed to bring foals till they are in the decline of life, or otherwise unable to bear their full share in rural labour. In the breeding of horses, as in all other kinds of live stock, it is of importance that, at the season of parturi¬ tion, there should be a suitable supply of food for the young. The time of covering mares ought, therefore, to be partly regulated by a due regard to this circumstance, and may be earlier in the south than in the north, where grass, the most desirable food both for the dam and foal, does not come so early by a month or six weeks. In Scotland it is not advantageous to have mares to drop their foals sooner than the middle of April; and, as the period of gestation is about eleven months, they ai'e usu¬ ally covered in May, or early in June. But if mares are intended to bring a foal every year, they should be co¬ vered from the ninth to the eleventh day after foaling, whatever may be the time; and the horse should be brought to them again nine or eighteen days afterwards. The mares are worked in summer as usual, and more moderately in the ensuing winter, till near the time of foaling, when, if the season be somewhat advanced, even though the pasture be not fully sufficient for their main¬ eul. s. -v tenance, they should be turned out to some grass field j near the homestead, and receive such additional supply of food as may be necessary, under sheds adjoining. It is^< both inconvenient and dangerous to confine a mare about to foal in a common stable, and still more so to leave her loose in a close stable among other horses ; and confine¬ ment is not much less objectionable after dropping her foal. Such sheds are also exceedingly convenient even after grass has become abundant, as the weather is often cold and rigorous during the month of May. When the foal is a few weeks old, the mare is again put to light work ; and she is separated from the foal altogether, after having nursed it for about six months. Breeding mares are evidently unable to endure the fa¬ tigue of constant labour for some months before and after parturition. This has led a few farmers to rear foals upon cow-milk; but the practice is neither common, nor likely ever to become so. The greater number of horses, there¬ fore, are bred in situations where a small portion of arable land is attached to farms chiefly occupied with cattle or sheep, or where the farms are so small as not to afford full and constant employment to the number of horses that must nevertheless be kept for the labour of particu¬ lar seasons. “ During the first winter, foals are fed on hay, with aFi little corn, but should not be constantly confined to the stable; for even when there is nothing to be got on the fields, it is much in their favour to be allowed exercise out of doors. A considerable proportion of succulent food, such as potatoes, carrots, and Swedish turnips (oil¬ cake has been recommended), should be given them through the first winter; and bean and peas meal has been advantageously substituted for oats, which, if allowed in a considerable quantity, are injurious to the thriving of the young animal, from their heating and astringent na¬ ture. Their pasture, during the following summer, de¬ pends upon the circumstances of the farms on which they are reared. In the second winter they are fed in much the same manner as in the first, except that straw may be given for some months instead of hay ; and in the third winter they have a greater allowance of corn, as they are frequently worked at the harrows in the ensuing spring, when about three years old.” (General Report of Scot¬ land, vol. iii. p. 183.) The rearing of horses is carried on in some places in so S; m systematical a manner, as to combine the profit arisingre from the advance in the age of the animals, with that of a moderate degree of labour before they are fit for the purposes to which they are ultimately destined. In the ordinary practice of the midland counties, the breeders sell them while yearlings, or perhaps when foals, namely, at six or eighteen months old, but most generally the lat¬ ter. They are mostly bought up by the graziers of Lei¬ cestershire, and the other grazing parts of that district, where they are grown among the grazing stock until the autumn following. At two years and a half old they are bought up by the arable farmers, or dealers of Bucking¬ hamshire, Berkshire, Wiltshire, and other western coun¬ ties, where they are broken into harness, and worked till they are five, or more generally six years old. At this age the dealers buy them up again to be sent to Lon¬ don, where they are finally purchased for drays, carts, waggons, coaches, the army, or any other purpose kr which they are found fit. (Marshall’s Economy of the Midland Counties, vol. i. p. 311.) , A similar mode of transferring young horses from ban to hand is common in the west of Scotland. The farmers of Ayrshire and the counties adjacent, who generally crop not more than one-fourth, or at most one-third, of their AGRICULTURE. 319 ul. arable land, and occupy the remainder with a dairy-stock, purchase young horses at the fairs of Lanark and Carn- ^ ^ath before mentioned,—work them at the harrows in the following spring when below two years old,—put them to the plough next winter at the age of two years and a half, and continue to work them gently till they are five years old, when they are sold again at the Rutherglen and Glasgow markets, at a great advance of price, to dealers and farmers from the south-eastern counties. A considerable number of horses, however, are now bred in the Lothians, Berwickshire, and Roxburghshire, the very high prices of late having rendered it profitable to breed them, even upon good arable land. But many farmers of these counties, instead of breeding, still prefer purchasing two and a half or three and a half year old colts, at the markets in the west country, or at Newcastle fair in the month of October. They buy in a certain number yearly, and sell an equal number of their work-horses before they are so old as to lose much of their value; so that their stock is kept up without any other loss than such as arises from accidents; and the greater price received for the horses they sell is often sufficient to cover any such loss. [General Report of Scotland, vol. iii. p. 182.) Cast: ion. Castration is performed on the males commonly when they are about a year old ; but a late writer strongly dis¬ approves of delaying this operation so long, and recom¬ mends twitching the colts (a practice well known to ram- breeders) any time after they are a week old, or as soon after as the testicles are come down ; and this method, he says, he has followed himself with great success. (Par¬ kinson on Live Stock, vol. ii. p. 74.) Another writer sug¬ gests, for experiment, the sparging of mares, thinking they would work better and have more wind than geldings. (Marshall’s Yorkshire, vol. ii. p. 169.) But he does not appear to have been aware that this is by no means a new experiment; for Tusser, who wrote in 1562, speaks of gelding fillies as a common practice at that period. The main objection to this operation is not that brood-mares would become scarce, as he supposes, but that, by inca¬ pacitating them from breeding, in case of accidents and in old age, the loss on this expensive species of live stock would be greatly enhanced. An old or lame mare would then be as worthless as an old or lame gelding is at present. 3. Feeding and Working. Aged world Select 'Goij torses. r Kffere,' wpot The age at which horses are put to full work, in the labours of a farm, is usually when four or five years old, according to the nature of the soil and the numbers of the team; but they are always understood to be able to pay for their maintenance after they are three years old, by occasional work in ploughing and harrowing. it is not so common a practice as it should be to sub¬ ject young horses of this kind to any regular course of training; but they are made familiar with their keeper a.s S00I1 as they are weaned, led about in a halter, rubbed down m the stable, and treated with gentleness ; and be- ()re being put to work, it is usual to place them under the large of a steady, careful servant, who very soon learns iem to drag a harrow alongside of an older horse, and ' Inwards to take their share of the labour at the plough, an ’. y degrees, in all the other work of the farm. ’th regard to the mode of feeding and working them, n t leir treatment in general, the practice is so various, ccordmg t° the state of agriculture in different districts, ( he circumstances of their owners, that all that can one .e *s to mention some leading points of ma- gement, in which all good farmers are agreed, is p Se , ct'on horses adapted to particular situations vu entIy a matter of primary consideration. It has been already hinted that the heavy, black cart-horses, so Agricul- much valued in London and a few other great towns, are ture. but ill adapted to the operations of modern husbandry and the nature of the soil and surface, and the situation of a farm in regard to markets, manure, and fuel, require some difference in the strength, activity, and hardiness of this instrument of labour. Accordingly, in the northern counties of Britain, where economy in this department is more attended to than in the south, we find horses of con¬ siderable strength, and a moderate share of activity, em¬ ployed on firm, cohesive soils ; and on light, friable soils, such as are possessed of more activity, not apt from their weight to be soon fatigued by working on an unequal sur¬ face, and able to endure travelling, with a moderate load, for a considerable distance, without injury. Whatever may be the description of horses employed, Kept in it is always a rule with good managers never to allowg00^0011*!^ them to fall off in condition so much as to be incapable oftion- going through their work without frequent applications of the lash. There is nothing which more clearly marks the unprosperous condition of a tenant, than the leanness of his working cattle, and their reluctant movements un¬ der this severe stimulus. There are particular operations, indeed, such as turnip-sowing, seeding fallows, harvest- work, &c. which require to be executed with so great dis¬ patch in our variable climate, that unusual exertions are often indispensable. At these times it is hardly possible, by the richest food and the most careful treatment, to prevent the animals from losing flesh, sometimes even when their spirit and vigour are not perceptibly impaired. Such labours, however, do not continue long, and should always be followed by a corresponding period of indul¬ gence. It is particularly dangerous and unprofitable to begin the spring labour with horses worn down by bad treatment during winter. Much has been said about the great expense of feeding Feeding, horses on corn and hay, and various roots have been re¬ commended as advantageous substitutes. That these ani¬ mals can ever be made to perform their labour, according to the present courses of husbandry, on carrots, turnips, potatoes, or other roots alone, or as their chief food, our own experience and observation lead us to consider as very improbable. They will work and thrive on such food; but they will work as much more, and thrive as much better, with oats or beans in addition, as fully to re¬ pay the difference in expense. One of the three meals a day which farm-horses usually receive may consist of roots, and a few of them every twenty-four hours are highly conducive to the health of the animals; but we have never had occasion to see any horse work regularly throughout the year, in the way they are usually worked in the best cultivated districts, without an allowance of at least an English peck of oats, or mixed oats and beans, daily, less or more at particular periods, but rather more than this quantity for at least nine months in the year. It has been already observed, that machines are in some places used for cutting hay and straw into chaff, for bruis¬ ing or breaking down corn, and for preparing roots and other articles by means of steam. The advantages of these practices, both in regard to the economy of food and the health of the animals, are too evident to require illustration. But the custom, which has been adopted by a few individuals, and injudiciously recommended by others, of cutting down oats with their straw into the state of chaff, without being previously threshed, is waste¬ ful and slovenly in the extreme. The proportion, as to quantity or quality, which the oats bear to the bulk of the straw, being various in every season, and almost in every field, the proper allowance of oats can be served out only 320 AGRICULTURE. Agricul- by first separating them from the straw, and then mixing ture. them with the cut straw or chaff, in suitable proportions, before being laid into the manger. Work per- The work performed is evidently a question of circum- formed stances, which does not admit of any precise solution. It has been observed in the section on tillage, that a two- horse plough may, on an average, work about an English acre a day throughout the year; and, in general, accoid- ing to the nature of the soil, and the labour that has been previously bestowed on it, a pair of horses, in ploughing, may travel daily from ten to fifteen miles, overcoming a degree of resistance equal to from four to ten hundred¬ weights. On a well-made road, the same horses will draw about a ton in a two-wheeled cart for twenty or twenty- five miles every day; and one of the better sort, in the slow movement of the carrier or waggoner, commonly draws this weight by himself on the best turnpike roads.. In some places horses are in the yoke, when the length of the day permits, nine hours, and in others ten hours a day ; but, for three or four months in winter, only from five to eight hours. In the former season they are allowed to feed and rest two hours from mid-day; and, in the latter, they have a little corn on the field when working as long as there is day-light, but none if they work only five or six hours. In the section on farm-buildings, we have described with some minuteness the construction and interior ar¬ rangement of modern stables ; and it is only necessary to add here, that the stable-management of horses has been greatly improved of late years. It is not long since there were instances, even in the Border counties, of horses being turned loose into a stable, without racks or mangers, and without any other litter than the straw intended for their food, which they tossed about in all directions. Even those farmers who found it necessary to confine them to separate stances, did not see the advantage of se¬ parating them by partitions, but left them standing, as is too generally the case at present with cattle, at liberty to inflict, and exposed to endure, serious injuries and priva¬ tions. When at last they were confined in stalls, it was common to place two in each, by way of saving room and the expense of partitions; and with the same view they were made to stand in double rows, one row on each gable or side-wall, the hind legs of each row so near those of the opposite one as to leave little room for carrying away their dung without danger, and to afford little security against the attacks from behind of vicious horses placed on the opposite sides of the stable. That all these incon¬ veniences are avoided in the present stables, must be evi¬ dent from the description already given, and the engraving there referred to. Stable-ma- It is now well understood that the liberal use of the nagement brush and the currycomb twice a day,—frequent but mo¬ derate meals, consisting of a due proportion of succulent joined to more solid food,—abundance of fresh litter, and great attention to method and cleanliness, are as indis¬ pensable in the stable of a farmer (as far as is consistent with a just regard to economy) as they have always been held to be in the treatment of horses kept for pleasure. Good dressing, with all well-informed and attentive men, is considered to be no less necessary to the thriving of the horses than good feeding: according to a common ex¬ pression, it is equal to half their food. We shall conclude this section with an extract from a recent publication, for the purpose of explaining the minutiae of management adopted in the most improved counties of Scotland. “ For about four months in summer, horses are fed on pastures, or on clover and ryegrass, and tares cut green and brought home to the stable or fold-yard; the latter method being by far the most economical and advantage- A ous. For other eight months they are kept on the straw of oats, beans, and peas, and on clover and ryegrass hay.^Jv; As soon as the grass fails towards the end of autumn, they have hay for a few weeks ; and when the days be¬ come so short as to allow of no more than from six to eight hours’ work, they are very generally fed with differ¬ ent kinds of straw, according to the circumstances of the farm. In the month of March they are again put to hay, till the grass is ready for being cut. Throughout all the year they are allowed more or less com when constantly worked ; and during the time they are on dry fodder, particularly when on straw, they have potatoes, yams, or Swedish turnips, once a day, sometimes boiled barley, and, in a few instances, carrots. A portion of some of these roots is of great importance to the health of horses, when succulent herbage is first exchanged for hay at the end of autumn; and it is no less so towards the latter end of spring, when hay has become sapless, and the la¬ bour is usually severe. At these two periods, therefore, it is the practice of all careful managers to give an ample allowance of some of these roots, even though they should be withheld for a few weeks during the intermediate period. “ The quantity of these different articles of food must depend on the size of the horses, and the labour they per¬ form ; and the value, upon the prices of different seasons, and in every season, on the situation of the farm with re¬ spect to markets, particularly for hay and roots, which bring a very different price near large towns, and at a few miles distance. It is for these reasons that the year¬ ly expense of a horse’s maintenance has been estimated at almost every sum from L.15 to L.40. But it is only necessary to attend to the expense of feeding horses that are capable of performing the labour required of them under the most correct and spirited management. Such horses are fed with oats, sometimes with beans, three times a day, for about eight months ; and twice a day for the other four, when at grass; and, at the rate of eight feeds per bushel, each horse will eat fifteen quarters of oats, or twenty bolls Linlithgow measure, in the year. When on hay, he will require about one stone of twenty- two pounds avoirdupois daily, and five pounds more if he does not get roots. One English acre of clover and rye¬ grass, and tares, may be necessary for four months soil¬ ing ; and a quarter of an acre of potatoes, yams, or Swedish turnips, during the eight months he is fed with hay or straw. The use of these roots may admit ot a small diminution of the quantity of corn in the winter months, or a part of it may be, as it almost always is, of an inferior quality.” The expense of a horse-plough must be different ac- • cording to the situation, but is in every case considerable.® ^ The feeding of the horses, with the interest of capital, de¬ cline in value, and loss by accidents or disease, and the charges for harness, shoeing, and farriery, were calculated, towards the latter end of the last war, when the prices were high, at from L.90 to L.100 per annum, which, wit the wages of the ploughman, would be equal to 40s. lor every acre of the land which they cultivated; but with pre¬ sent prices an abatement may be made of 20 or 25 per cent., reducing the whole charges upon a plough, wages include!, to about L.100 per annum, and the expense per acre to 30s. or 32s. It is no doubt true that the expense is in many places considerably less than this; but we speak hereo horses fully employed throughout the year, and in J e improved system of husbandry. Farmers who keep their accounts in a proper manner charge for every days wor of a man and a pair of horses from 7s. 6d. to 10s.; an General manage¬ ment in Scotland. -{p- gr AGRICULTURE. A -jl- when land is in an ordinary state of cultivation, it is 1 tit • sometimes let out to plough at the rate of 6s. to 8s. per L^^aCre. Wieer It has been long alleged that oxen might be beneficial- oxen (ay ]y substituted for horses, in the common operations of be u; agriculture; and a great many calculations have been sub- [llste: 01 mitted to the public on both sides of the question. Start- 1 ling as it may seem, however, these calculations prove nothing. The first point is to show, that the two animals are equally adapted to every sort of farm labour. There are other elements which enter into this question than the actual expenditure on either side; and with reference to the present state of agriculture in this country, we hold it as a fact ascertained by general experience, that oxen cannot be employed with advantage, except in particular sorts of labour which do not go on all the year round, but are only performed occasionally or at certain seasons. The constant employment of oxen, to the entire exclusion of horses, is, we venture to assert, impracticable in this country, and, if it were practicable, would not be profit¬ able. It is readily admitted, that oxen are well adapted to the ploughing of coarse tough swards, .and other lands so much occupied with stones or roots as to require a slow and steady power. They have also been found use¬ ful for threshing-machines worked by animal power, for the same reason. But in almost all the other kinds of labour necessary upon an extensive farm, oxen, such at least as are bred in this country, are troublesome, ineffi¬ cient, slow, and unprofitable labourers. They are not suited to the cart or waggon, even on our fields, and far less for travelling upon our public roads. They cannot perform their work with the dispatch necessary in our variable climate at seedtime and harvest; and in the pre¬ paring, manuring, and seeding of large fields of turnip, a process which calls for so much exertion and dispatch in Norfolk and other turnip counties, the employment of oxen is entirely inadmissible. Within certain limits a horse will work according as he is fed; but if an ox is pushed beyond his natural step, he is soon rendered useless. On a practical question of this nature it is experience alone that can decide ; and there is none as to which gene¬ ral experience is more conclusive. In the rude state of agriculture which prevailed in this country before the in¬ troduction of clover and turnips, oxen were, as they still continue to be in some parts of the Continent, more gene* rally employed in the home work of a farm than horses; but in the progress of improvement, oxen have been gra- dually laid aside, till horses are now, with comparatively few exceptions, universally employed in their stead. So ; much is this the case, that one might almost estimate be- j forehand the state of agriculture in any district where (,xen are in general use. But the change from oxen to worses, in the labours of agriculture, is not confined to this ( uuntry. A similar change has been long going on on the ontinent, particularly in France, where, according to l r best agricultural writers, the horse is preferred for , same reasons as in this country. The advocates for le use pf oxen, in fact, are in general persons of little or 110 P'j^lkal knowledge, who look only to the original cost . t le comparative expense of maintaining the animals, j!1!/1 t"e accidents and diseases to which the horse is e; but they do not take into view what that cost and 1-t expense of maintenance would be if oxen were to ^!ne ‘jdo general use, and how far this change would ect the supply of our butcher market; nor do they con- ().er t le l°ss upon the ploughman's wages, when he goes n!an aiCre a ^ay or more with the one species of ani- a s, and not more than half as much with the other. VOL. II. 321. T iey might reflect too upon the necessity there is for the Acn-Icub empJoyment of horses in dray^s and waggons in our public ture. streets and in long journeys. To provide for the neces-^-^*^.. sary supply, these horses must be reared as a part of the farmer s live stock; and as he begins to work them so early as at three years old, they return to him much more than the price of their food, before they come to the age of five or six years, which is as soon as they are fit for the wag¬ goner or the drayman. With all these considerations in view, the arguments drawn from the husbandry of the Greeks and Romans, and the modern practice of other countries, wifi have no more weight with the enlightened farmers of Britain than if it were attempted to prove the superiority of manual and animal labour over machinery in threshing and other operations. Such men will always continue to apply each species of animal to its proper use, and seek for labour from the horse, and beef from the ox; improving the breeds of both with a view to these distinct objects, instead of vainly attempting to obtain meat and labour from the latter animal. By this management, as we shall see immediately, our cattle are now prepared for the butcher at a much earlier period than formerly, and afford an adequate return in their carcass alone. Sect. II. Cattle. The purposes for which cattle are kept being more Variety of various, and cattle being also for the most part not so breeds of completely domesticated as horses, this species includescattle- a much greater number of breeds and varieties. The dif¬ ferent races have been distinguished generally by the length of their horns, or by their having no horns at all; and again subdivided, and more particularly described under the names of the counties or districts where they are supposed to have originated, where they most abound, or where they exist in the greatest purity. In Britain, as in most other countries, horses are useful only for the labour they perform, though it is probable that nothing but prejudice prevents them from enlarging, at least occasionally, the supply of human food; and to render them fit for labour, they must sooner or later in their lives be entirely subjected to the care and control of man. Cattle, on the other hand, except the few kept for labour and for their milk, have not, till of late (and even now only in particular countries), been the objects of that discipline and those experiments which seek to restrain habits acquired in a state of nature—to improve forms and proportions, perpetuated and somewhat varied by climate, surface, and herbage—and to cultivate and bring to perfection, with the greatest possible economy, all those valuable properties with which nature has en¬ dowed the inferior animals for the subsistence and the - comfort of man. In most parts of the world cattle are still merely the creatures of soil and climate; and it is a striking evidence of the greater progress of social im¬ provement in Britain, that we possess races of cattle and sheep, formed in a great measure by skill and industry, which excel beyond all comparison those of every other country. The three great products of cattle—meat, milk, and la-Different hour—have each of them engaged the attention of British products, agriculturists; but experience has not hitherto justified the expectation that has been entertained of combining all these desirable properties, in an eminent degree, in the same race. That form which indicates the property of yielding the most milk, differs materially from that which we know from experience to be combined with early ma¬ turity and the most valuable carcass; and the breeds which are understood to give the greatest weight of meat 2 s 322 AGRICULTURE.

As we propose to treat of the produce and manufacture of milk in a separate article (see Dairy), we shall there have occasion to notice those breeds of which the females are most valuable for the dairy ; only referring at present to Plate XIII. for an engraving of the Ayrshire cow, an ex¬ cellent race, spread over that and the counties adjacent. And as cattle are seldom or never reared exclusively, or even chiefly, for the purpose of labour, which is now in most parts of Britain performed entirely by horses, it will be sufficient to apply our remarks in an especial manner to the races themselves, and the modes of treatment which are best adapted to the production of beef. “ Whatever be the breed,” says Mr Culley, <£ I pre¬ sume that, to arrive at excellence, there is one form or shape essential to all, which form I shall attempt to give in the following description of a bull. “ The head of the bull should be rather long, and muz¬ zle fine ; his eyes lively and prominent; his ears long and thin; his horns white; his neck rising with a gentle curve from the shoulders, and small and fine where it joins the head ; his shoulders moderately broad at the top, joining full to his chine and chest backwards, and to the neck-vein forwards; his bosom open; breast broad, and projecting well before his legs; his arms or fore thighs muscular, and tapering to his knee; his legs straight, clean, and very fine boned; his chine and chest so full as to leave no hollow behind the shoulders ; the plates strong, to keep his belly from sinking below the level of his breast; his back or loin broad, straight, and flat; his ribs rising one above another, in such a manner that the last rib shall be rather the highest, leaving only a small space to the hips or hooks, the whole forming a round or barrel¬ like carcass; his hips should be wide placed, round or globular, and a little higher than the back; the quarters (from the hip to the rump) long, and instead of being square, as recommended by some, they should taper gra¬ dually from the hips backward, and the turls or pottbones not in the least protuberant; rump close to the tail; the tail broad, well haired, and set on so high as to be in the same horizontal line with his back.” (Culley on Live Stock, p. 38.)

The Long-honied or Lancashire breed of cattle is dis¬ tinguished from others by the length of their horns, the thickness and firm texture of their hides, the length and closeness of their hair, the large size of their hoofs, and coarse, leathery, thick necks : they are likewise deeper in their fore quarters and lighter in their hind quarters than most other breeds,—narrower in their shape, less in point of weight, than the short-horns, though better weighers in proportion to their size; and though they give consider¬ ably less milk, it is said to afford more cream in propor¬ tion to its quantity. They are more varied in their colour than any of the other breeds; but, whatever the colour be, they have in general a white streak along their back, which the breed¬ ers term finched, and mostly a white spot on the inside of the hough, (/rf. p. 53.) In a general view, this race, notwithstanding the singu¬ lar efforts that have been made towards its improvement, remains with little alteration ; for, excepting in Leices¬ tershire, none of the subvarieties (which differ a little in almost every one of those counties where the long-horns prevail (have undergone any radical change, nor any ob- brought from the banks of the Trent about 90 years which were crossed with bulls from Westmoreland andU rte Lancashire. Mr Bakewell of Dishley, in Leicester¬ shire, afterwards got the lead as a breeder, by selecting from the Canley stock; and the stocks of several other eminent breeders have been traced to the same source. (Marshall’s Midland Counties, vol. i. p. 318.) See Plate XIV. 2. The Short-horned, sometimes called the Dutch breed, is known by a variety of names, taken from the districtsh>k where they form the principal cattle-stock, or where most attention has been paid to their improvement. Thus, dif¬ ferent families of this race are distinguished by the names of the Holderness, the Teeswater, the Yorkshire, Durham, Northumberland, and other breeds. The Teeswater breed, a variety of short-horns, established on the banks of the Tees, at the head of the vale of York, is at present in the highest estimation, and is alleged to be the true York¬ shire short-horned breed. Bulls and cows from this stock, purchased at most extraordinary prices, are spread over all the north of England and the border counties of Scot¬ land. The bone, head, and neck of these cattle are fine; the hide is very thin, the chine full, the loin broad, and the carcass throughout large and well fashioned; and the flesh and fatting quality equal, or perhaps superior, to those of any other large breed. The short-horns give a greater quantity of milk than any other cattle; a cow usually yielding 24 quarts of milk per day, making three firkins of butter during the grass season. Their colours are much varied, but they are generally red and white mixed, or what the breeders call flecked. See Plate XIV. “ The heaviest and largest oxen of the short-horned breed, when properly fed, victual the East India ships, as they produce the thickest beef, which, by retaining its juices, is the best adapted for such long voyages. Our royal navy should also be victualed from these; but, by the jobs made by contractors, and other abuses, I am afraid our honest tars are often fed with beef of an inferior quality. However, the coal ships from Newcastle, Shields, Sunderland, &c. are wholly supplied with the beef of these valuable animals. “ These oxen commonly weigh from 60 to 100 stone (14 lb. to the stone), and they have several times been fed to 120, 130, and some particular ones to upwards ol DO stone, the four quarters only.” (Culley on Live Stock, P* 48*) 3. The Middle-horned breeds comprehend in like manner j several local varieties, of which the most noted are theh Devons, the Sussexes, and the Herefords; the two last, according to Mr Culley, being varieties of the first, though of a greater size, the Herefords being the largest. These cattle are the most esteemed of all our breeds for the draught, on account of their activity and hardiness. They do not milk so well as the short-horns, but are not de¬ ficient in the valuable property of feeding at an early age, when not employed in labour. The Devonshire cattle are “ of a high red colour (if an)! white spots, they reckon the breed impure, particularly » those spots run into one another), with a light dun ring round the eye, and the muzzle of the same colour; fine in the bone, clean in the neck, horns of a medium length bent upwards, thin-faced and fine in the chops, wide m the hips, a tolerable barrel, but rather flat on the sl^e®’ tail small and set on very high; they are thin-skinne'? and silky in handling, feed at an early age, or arrive a maturity sooner than most other breeds.” (Culley ^ e» AGRICULTURE. v cul- Live Stock, p. 51.) Another writer observes, that they Iare a model for all persons who breed oxen for the yoke, ty'^(Parkinson on Live Stock, vol. i. p. 112.) The weight of the cows is usually from 30 to 40 stone, and of the oxen from 40 to 60. The North Devon variety, in particular, from the fineness in the grain of the meat, is held in high estimation in Smithfield. (Dickson’s Practical Agricul¬ ture, vol. ii. p. 120.) Sus sand The Sussex and Herefordshire cattle are of a deep red He ml colour, with fine hair and very thin hides; neck and head clean; horns neither long nor short, rather turning up at the points; in general they are well made in the hind quarters, wide across the hips, rump, and sirloin, but nar¬ row in the chine ; tolerably straight along the back ; ribs too flat; thin in the thigh ; and bone not large. An ox, six years old, when fat, will weigh from 60 to 100 stone, the fore quarters generally the heaviest. The oxen are mostly worked from three to six years old, sometimes till seven, when they are turned off for feeding. The Here¬ ford cattle are next in size to the Yorkshire short-horns. Both this and the Gloucester variety are highly eligible as dairy stock, and the females of the Herefords have been found to fatten better at three years old than any other kind of cattle except the spayed heifers of Norfolk. (Mar¬ shall’s Economy of Gloucestershire f Pol: 4. The Polled or hornless breeds. The most numerous tow and esteemed variety is the Galloway breed, so called from the province of that name, in the south-west of Scot¬ land, where they most abound. The true Galloway bul¬ lock “ is straight and broad on the back, and nearly level from the head to the rump; broad at the loins, not, how¬ ever, with hooked bones, or projecting knobs; so that when viewed from above, the whole body appears beautifully rounded, like the longitudinal section of a roller. He is long in the quarters, but not broad in the twist. He is deep in the chest, short in the leg, and moderately fine in the bone, clean in the chop and in the neck. His head is of a moderate size, with large, rough ears, and full but not prominent eyes or heavy eye-brows, so that he has a calm, though determined look. His well-proportioned form is clothed with a loose and mellow skin, adorned with long, soft, glossy hair.’’ ( Galloway Report, p. 236.) The pre¬ vailing coiour is black or dark brindled; and, though they are occasionally found of every colour, the dark colours are uniformly preferred, from a belief that they are con¬ nected with superior hardiness of constitution. The (lalloways are rather under-sized, not very different from the size of the Devons, but as much less than the long¬ horns as the long-horns are less than the short-horns. On the best farms the average weight of bullocks three years and a half old, when the greater part of them are driven to the south, has been stated at about forty stone avoirdupois. Some of them, fattened in England, have been brought to nearly one hundred stone. See Hate XV. The general properties of this breed are well known in almost every part of England, as well as in Scotland, they are sometimes sent from their native pastures di¬ rectly to Smithfield, a distance of 400 miles, and sold at once to the butcher ; and in spring they are often shown •n JS/oriolk, immediately after their arrival, in as good con- itmn, or even better than when they began their journey. 1. ‘HI feeding, there is perhaps no breed that sooner a ams maturity, and their flesh is of the finest quality. , r . ky was misinformed about the quantity of milk ey yield, which, though rich, is by no means abundant. 323 It is alleged not to be more than seventy or eighty Agricul- years since the Galloways were all horned, and very much ture. the same, in external appearance and character, with the^-^V^^ breed of black-cattle which prevailed over the west of Scotland at that period, and which still abound in perfec¬ tion, the largest sized ones in Argyllshire, and the smaller in the Isle of Skye. The Galloway cattle, at the time al¬ luded to, were coupled with some hornless bulls, of a sort which do not seem now to be accurately known, but which were then brought from Cumberland ; the effects of which crossing were thought to be the general loss of horns in the former, and the enlargement of their size; the con¬ tinuance of a hornless sort being kept up by selecting only such for breeding, or perhaps by other means, as by the practice of eradicating with the knife the horns in their very young state.” (Coventry on Live Stock, p. 28.) The Galloway cattle, besides occupying almost exclu¬ sively the stewartry of Kirkcudbright and the shire of Wig- ton, the two divisions of Galloway, are now spread over the adjoining county of Dumfries, and are to be found in smaller numbers in most of the other districts of Scot¬ land. The cattle of Angus or Forfarshire, on the east coast, many of which are also without horns, resemble the Galloways in their colour, size, and general properties. The Suffolk Duns, according to Mr Culley, are nothing Suffolk more than a variety of the Galloway breed. Fie supposes Duns, them to have originated in the intercourse that has long subsisted between the Scotish drovers of Galloway cattle, and the Suffolk and Norfolk graziers who feed them. The Suffolks are almost all light duns, thus differing from the Galloways; and are considered a very useful kind of little cattle, particularly for the dairy.1 5. The cattle of the Highlands of Scotland are divided High- into a number of local varieties, some of which differ ma- lands, terially from others, probably owing to a difference in the climate and the quality of the herbage, rather than to their being sprung from races originally distinct, or to any great change effected either by selection or by crossing with other breeds. It is only of late that much attention has been paid to their improvement in any part of that extensive district; and in the northern and central High¬ lands the cattle are yet, for the most part, in as rude a state, and under management as defective, as they were some centuries ago. These cattle have almost exclusive possession of all that division of Scotland, including the Hebrides, marked off by a line from the Frith of Clyde on the west to the Moray Frith on the north, and bending towards the east till it approaches in some places very near to the German Ocean. Along the eastern coast, north of the Frith of Forth, the Highland cattle are intermixed with various local breeds, of which they have probably been the basis. There are more or less marked distinctions among tlie cattle of the different Highland counties; and, in com¬ mon language, we speak of the Inverness-shire, the Banff¬ shire, &c. cattle, as if they were so many separate breeds; but it is only necessary in this place to notice the two more general varieties, now clearly distinguishable by their form, size, and general properties. The most valuable of these are the cattle of the Western West Highlands and Isles, commonly called the Argyllshire breed, Highlands, or the breed of the Isle of Skye, one of the islands attach-Argyll- ed to the county of Inverness. The cattle of the Hebrides or are called Kyloes, a name which is often applied in theb ^e" south to all the varieties of the Highland cattle, not, as a late writer (Dickson’s Practical Agriculture, vol. ii. 1 Culley o;i Live Stuck, p. G6; and Parkinson on Live Stuck, vol. i. p. 118. j 324 AGRICULTURE. Agricul lure. p. 1124)) has imagined, from the district in Ayrshire called Kyle, where very few of them are kept, but from their crossing, in their progress to the south, the kyloes or fer¬ ries in the mainland and Western Islands, where these cattle are found in the greatest perfection. ( General Re¬ port of Scotland, vol. iii. p. 26.) A bull of the Kyloe breed should be of a middle size, capable of being fattened to fifty stone avoirdupois. His colour should be black, or dark brown, or reddish brown, without any white or yellow spots#- His head should be rather small, his muzzle fine, his horns equable, not very thick, of a clear green and waxy tinge; his general ap¬ pearance should combine agility, vivacity, and strength ; and his hair should be glossy, thick, and vigorous, indi¬ cating a sound constitution and perfect health. See Plate XV. . For a bull of this description Mr Macneil of Colonsay refused 200 guineas; and for one of an inferior sort he ac¬ tually received L.170 sterling. Mr Macdonald of Staffa^ bought one, nine years old, at 100 guineas. {Report oj the Hebrides, p. 425.) The lean weight of the best stock, from three to four years old, when they are commonly sold to the south, is from twenty-six to thirty stone the four quarters; but when brought to good pastures, they can be easily raised to fifty stone and upwards. There is perhaps no other breed whose weight depends so much on feeding, nor any that fattens and grows so much at the same time. They are exceedingly hardy, easily maintained, speedily fatten¬ ed on pastures where large animals could scarcely sub¬ sist; the beef is fine in the grain, and well marbled or intermixed with fat; and their milk is rich, but small in quantity. Norlands. The other variety of Highland cattle is the Norlands, or North Highlanders, including the stocks of the counties of Ross, Cromarty, Sutherland, Caithness, and parts adja¬ cent. Their hides are generally coarse, backs high and narrow, ribs flat, bones large, and legs long and feeble for the weight of the chest; and they are considered very slow feeders. But though this description be but too ap¬ plicable to the cattle of the greater part of that remote district, considerable improvement has been effected in many parts of it, by crossing with the Skye or Argyll breeds, within the last twenty years. The cattle of the northern isles of Orkney and Zetland are of a most diminutive size; an ox weighing about sixty pounds a quarter, and a cow forty-five pounds. They are of all colours, and their shapes are generally bad; yet they give a quantity of excellent milk, fatten rapidly when put on good pastures, and, in their own district, are considered strong, hardy, and excellent workers, when well trained to the yoke, and so plentifully fed as to en¬ able them to support labour. 6. It has been already observed, that all along the low¬ lands of the eastern coast of Scotland, to the north of the Frith of Forth, there are varieties of cattle which, what¬ ever may have been their origin, differ as much from the cattle of the western and northern Highlands as most of those that have been described as separate breeds. Of the Fifeshire cattle, Mr Culley observes, “ You would at first imagine them a distinct breed, from their upright white horns, being exceedingly light-lyered and thin-thigh¬ ed ; but I am pretty clear it is only from their being more nearly allied to the kyloes, and consequently less of the coarse kind of short-horns in them.” (Culley on Live Stock, p. 69.) Notwithstanding this opinion, the cattle of the north-eastern counties of Scotland require, for every useful purpose, to be mentioned separately from the High¬ land breeds; and as all of them have a general resemblance, Orkney and Bet- .and. Fifesliire. it will only be necessary, in this place, to notice the Fife As ^ cattle in particular. t‘ There are various traditions about the origin of this''-' v variety. It is said to have been much improved by Eng¬ lish cows, sent by Henry VII. to his daughter, the consort of James IV., who usually resided at the palace of Falkland in that county ; and as there is some resemblance between the cattle of Fife and Cambridgeshire, they are supposed to have been brought originally from the latter county. Others ascribe the origin of the present breed to bulls and cows sent by James VI. (James I. of England), in payment of the money which his obliging neighbours in Fife are said to have advanced for his equipment, v/hen he went to take possession of the English throne. {Report of Naim and Moray, p. 305.) The prevailing colour of the Fife cattle is black, though sometimes spotted or streaked with white, and some of them are altogether grey. The horns are small, white, generally pretty erect, or at least turned up at the points, bending rather forward, and not wide-spread like the Lan¬ cashire long-horned breed. The bone is small in propor¬ tion to the carcass, the limbs clean but short, and the skin soft. They are wide between the hook-bones; the ribs narrow, wide set, and having a great curvature. They fatten quickly, and fill up well at all the choice points; are hardy, fleet, and travel well, and are excellent for labour, both at plough and cart. A good cow of this breed gives from eighteen to twenty-four quarts of milk per day, yielding from seven to nine pounds of butter, and from ten to twelve pounds of cheese per week (twenty- four ounces to the pound), for some months after calving. {Fife Report, p. 251 and 253.) The cattle of Aberdeenshire, the largest of which are Ait ms. said to have been produced by crossing with Fife bulls,sLi have been long highly esteemed in the southern markets. It is observed, that every succeeding generation of them has increased in size for the last 30 years, and that the native breed has doubled its former weight since the in¬ troduction of turnips. {Aberdeenshire Report, p. 468.) The colour is commonly black, but thei’e are many of a red and brindled colour. They are thinner in the buttock in proportion to their weight, and deeper in the belly in proportion to their circumference, than the West High¬ landers, and they yield a much larger quantity of milk. Many of them are brought to the south of Scotland, and kept during winter in the straw-yards, for which they suit better than smaller cattle, as they are not so impatient ot confinement. The ordinary weight of middle-sized oxen, at from three to five years old, is from forty to fifty stone; but after being worked for some time, and thoroughly fattened, they have been known to reach double this weight. 7. Of the Welsh cattle “ there seem to be two distincty |>. kinds. The large sort are of a brown colour, with some white on the rump and shoulders, denoting a cross from the long-horns, though in shape not the least resembling them. They are long in the legs, stand high according to their weight, are thin in the thigh, and rather narrow in the chine ; their horns are white, and tui’ned upwards; they are light in flesh, and, next to the Devons, well formed for the yoke; have very good hoofs,. and walk light and nimble. The other sort are much more valuable; colour black, with very little white; of a good useful form, short in the leg, with round, deep bodies ; the hide is rather thin, with short hair; they have a lively look and a good eye; and the bones, though not very small, are neither large nor clumsy; and the cows are considered good milkeis- (Parkinson on Live Stock, vol. i. p. 135.) , 8. The Alderney cattle are to be met with only abou A AGRICULTURE. At'rJl’ W’ Wild: Lreet; . the seats of a few great landholders, where they are kept chiefly for the sake of their milk, which is very rich, s though small in quantity. This race is considered by very competent judges as too delicate and tender to be propa¬ gated to any extent in Britain, at least in its northern parts. Their colour is mostly yellow or light red, with white or mottled faces : they have short, crumpled horns, are small in size, and very ill shaped ; yet they are fine¬ boned in general; and their beef, though high-coloured, is very well flavoured. I have seen, says Mr Culley, some very useful cattle bred from a cross between an Alderney cow and a short-horned bull. 9. The last variety of cattle we shall mention is the mid breed, which is found only in the parks of a few great proprietors, who preserve the animals as a curiosity. Those kept at Chillingham Castle in Northumberland, a seat belonging to the earl of Tankerville, have been very accurately described in the Northumberland Report, and in Mr Gulley’s book on Live Stock, so often quoted in this article. “ Their colour is invariably of a creamy white; muzzle black; the whole of the inside of the ear, and about one- third of the outside, from the tips downward, red'; horns white, with black tips, very fine, and bent upwards ; some of the bulls have a thin upright mane, about an inch and a half or two inches long. The weight of the oxen is from 35 to 45 stone, and the cows from 25 to 35 stone the four quarters (14 pound to the stone). The beef is finely marbled, and of excellent flavour. “ From the nature of their pasture, and the frequent agitation they are put into by the curiosity of strangers, it is scarce to be expected they should get very fat; yet the six-years-old oxen are generally very good beef, from whence it may be fairly supposed that, in proper situa¬ tions, they would feed well. “ At the first appearance of any person they set off in lull gallop, and, at the distance of about 200 yards, make a wheel round and come boldly up again, tossing their heads in a menacing manner; on a sudden they make a lull stop, at the distance of 40 or 50 yards, looking wildly at the object of their surprise, but, upon the least motion being made, they all again turn round, and fly off with equal speed, but not to the same distance, forming a shorter circle, and again returning with a bolder and more threaten¬ ing aspect than before ; they approach much nearer, pro¬ bably within 30 yards, when they again make another stand, and again fly off: this they do several times, short¬ ening their distance, and advancing nearer and nearer, till they come within such a short distance that most people link it prudent to leave them, not choosing to provoke them further. “ Ule mode of killing them was perhaps the only mo¬ dern remains of the grandeur of ancient hunting. On notice being given that a wild bull would be killed on a certain day, the inhabitants of the neighbourhood came mounted and armed with guns, &c. sometimes to the amount of 100 horse and 400 or 500 foot, who stood upon |va s orS0f into trees, while the horsemen rode off the mil from the rest of the herd, until he stood at bay, when f ln^rksman dismounted and shot. At some of these mntings, 20 or 30 shots have been fired before he was s.u Ueti’ On such occasions the bleeding victim grew desperately furious, from the smarting of his w'ounds, and c shouts of savage joy that were echoing from every t]U t i ^rom ti16 number of accidents that happened, ui:> dangerous mode has been little practised of late years, it paik-keeper alone generally shooting them with a nfled gun at one shot. b ^ S M hen the cows calve, they hide their calves for a 325 week or ten days m some sequestered situation, and go Aericul and suckle them two or three times a day. If any per- ture son come near the calves, they clap their heads close to'^-^ the ground, and lie like a hare in form, to hide them¬ selves. This is a proof of their native wildness, and is corroborated by the following circumstance that happened to the writer of this narrative (Mr Bailey of Ghillingham), who found a hidden calf, two days old, very lean and very weak. On stroking its head it got up, pawed two or three times like an old bull, bellowed very loud, stepped back a few steps, and bolted at his legs with all its force; it then began to paw again, bellowed, stepped back, and bolted as before; but knowing its intention, and stepping aside, it missed him, fell, and was so very weak, that it could not rise, though it made several efforts:—but it had done enough;—the whole herd were alarmed, and, coming to its rescue, obliged him to retire; for the dams will allow no person to touch their calves, without attacking them with impetuous ferocity. “ When a calf is intended to be castrated, the park- keeper marks the place where it is hid, and when the herd are at a distance, takes an assistant with him on horse¬ back ; they tie a handkerchief round the calf’s mouth to prevent its bellowing, and then perform the operation in the usual way, with as much expedition as possible. When any one happens to be wounded, or is grown weak and feeble through age or sickness, the rest "of the herd set upon it and gore it to death.” (Culley on Live Stock, p. 73.) 2,. Breeding and Rearing. The pedigrees of the best cattle have been preserved Great at- with no less care, in several parts of England, than those tention to of race-horses ; and in the selection of breeders, the pro-breeding, perties of the family from which they have descended are matters of scarcely less importance than the form of the young animals themselves. In rearing calves, the blood and the colour seem to be more attended to by breeders in general than the form. (Marshall’s York¬ shire, vol. ii. p. 203.) The extraordinary prices paid for the best bred bulls and cows, show that this attention has not been without its reward. The best bulls are either let out for the season, or cows Bulls, are brought to, them at a certain rate per head. The practice of letting bulls is said to have originated with Mr Bakewell (Marshall’s Midland Counties, vol. i. p. 334), who, so far back as 1792, let a bull for 152 guineas, to be used only four months (Parkinson on Live Stock, vol. ii. p. 469); and five guineas per cow were about that time commonly paid to him and other eminent breeders. The age at which bulls should begin to be employed, Age of and the number of seasons they should be allowed to breeding serve, as well as the age at which the females should be¬ gin to breed, are points regarding which practice is by no means uniform. In the midland counties the bulls are pretty commonly allowed to leap while yearlings, and, if good stock-getters, are kept on as long as they will serve, perhaps till they are 10 or 12 years old. In other places they are employed only three seasons, for the first time at two years old. The females in some in¬ stances bring their first calf at the age of two years, but more commonly, perhaps, not till they are a year older; and in some of the Highland districts, where, owing to a want of proper nourishment in their infancy, they are later in reaching their full growth, the females do not often become mothers till they are about four years old. The period of gestation with cows has been found, perio<] of upon an average of a great number of experiments, to be gestation, about 40 weeks; and they seldom bring more than one 326 AGRICULTURE. Agncul- calf at a birth. When they produce twins, one of them ture- a male and the other a female, the latter, which is called a, free martin, is commonly considered to be incapable of UniT mar* Procreati°n* Yet there seem to have been well-authenti¬ cated instances to the contrary. (Farmer s Magazine, vol. vii. p. 462, and vol. viii. p. 466.) Calves. Though calves are dropped at all seasons of the year, the spring is the most common period; and, except in those districts where the fatting of calves is an object of importance, it is probably the most advantageous time, as the calves, having all the grass season before them, be¬ come sufficiently strong for enduring the change to a less agreeable food in the ensuing winter. A calf newly weaned seldom thrives well during that period, unless it is pampered with better food than usually falls to the share of young animals. Suckling. In Galloway and the Highlands of Scotland the almost invariable practice is to allow the calves to suck the cows, and this commonly as long as the cows give any milk; most of them, indeed, will not give down their milk unless the calf is put to one side of the udder, while the milk¬ maid draws the teats on the other side; and if the maid gives the least interruption to her rival, the cow punishes the fraud by a blow with her leg, often overturning both the offender and the milking-pail. (General Report of Scotland, vol. iii. p. 47.) Where there is not an inclosure for confining the calves when they are put to grass, a muzzle is made for the nose, with iron spikes fastened on it, which prick the cow when the calf attempts to suck at forbidden times, and obliges her to keep it off till the muzzle be removed at the stated periods of milking. But this is too troublesome where many of them are reared, in which case they are kept apart from the cows till the hours of milking. This natural method of rearing calves is common, at least for a short time, in other parts of Britain. Bull- calves, and sometimes high-bred heifers, are suffered to remain at the teat until they be six, nine, or perhaps twelve months old; letting them run either with their dams, or more frequently, especially when the dairy is an object, with less valuable cows or heifers bought in for the purpose, and, when the intention is fulfilled, sold or fatted; each cow being generally allowed one male calf or two females. Hearing “ The best method of the dairymen is this :—The calves calves. suck a week or a fortnight, according to their strength (a good rule) ; new milk in the pail, a few meals ; next new milk and skim-milk mixed, a few meals more ; then skim- milk alone, or porridge made with milk, water, ground oats, &c. and sometimes oil-cake, until cheese-making commence; after which, whey porridge, or sweet whev, in the field; being careful to house them in the night, until warm weather be confirmed.” (Marshall’s Midland Counties, vol. i. p. 338.) Fed from This method of suckling is not, however, free from ob- a pail. jection; and, in the ordinary practice of rearing calves, it is held to be a preferable plan to begin at once to learn them to drink from a pail. The calf that is fed from the teat must depend upon the milk of its dam, however scanty or irregular it may be; whereas, when fed from a dish, the quantity can be regulated according to its age; and various substitutes may be resorted to, by which a part of the milk is saved for other purposes, or a greater number of calves reared upon the same quantity. ( Gene¬ ral Report of Scotland, vol. iii. p. 51.) Yet it would seem to be a good practice to allow calves to suck for a few days at first, if there was no inconvenience to be appre¬ hended both to themselves and their dams from the se¬ paration afterwards. When fed from the pail, the average allowance to a A calf is about two imperial wine gallons of milk daily for 12 or 13 weeks ; at first fresh milk as it is drawn from the^ cow, and afterwards skim-milk. But after it is three or^u four weeks old, a great variety of substitutes for milk are f1 used in different places, of which linseed, oil-cake, meal,0" and turnips, are the most common. The practice, how¬ ever, varies so much, no particular substitute being in ge¬ neral use, nor the quantity, nor the time of giving it, ac¬ curately determined, that it would be of no use to go into details here. For the feeding and treatment of fattening calves, see Dairy. It is a rule, applicable to all kinds of live stock, to per-Cas form castration, where that is to be done, while the ani¬ mals are yet very young, and just so strong as to endure this severe operation without any great danger of its proving fatal. The males, accordingly, are cut commonly when about a month old, and the females at the age of from one to three months; but in Galloway, where more heifers are spayed than perhaps in all the island besides, this is seldom done till they are about a year old. The treatment of young cattle from the time they are Yoi separated from their dams, or able to subsist on the com-catt mon food of the other stock, must entirely depend upon the circumstances of the farm on which they are reared. In summer their pasture is often coarse, but abundant; and in winter all good breeders give them an allowance of succulent food along with their dry fodder. The fol¬ lowing description is not less applicable to the best prac¬ tice in the rearing of all cattle bred on arable land, than to the short-horns:— “ The first winter they have hay and turnips; the fol¬ lowing summer, coarse pasture ; the second winter, straw in the fold-yard, and a few turnips once a day, in an ad¬ joining field, just sufficient to prevent the straw from binding them too much ; the next summer, tolerably good pasture; and the third winter, as many turnips as they can eat, and in every respect treated as fatting cattle.” (Culley on Live Stock, p. 47.) The only difference is, that, where straw is in great abundance, the cattle some¬ times do not eat their turnips on the fields, but in the fold-yard. In those situations where turnips cannot be extensively cultivated, or where cattle are sold for graz¬ ing instead of being fattened, a Smaller allowance of turnips the third winter is made to suffice. :ul. e. V it? 3. Fatting. Cattle are fatted on grass in summer, commonly onDif pastures, but in a few instances on herbage cut and con-fin sumed in feeding-houses or fold-yards; and in winter by!0i'j far the greater number are fatted on turnips, along with^ hay or straw. Oil-cake, carrots, potatoes, and other articles of food, are used occasionally, and in particular districts; oil-cake chiefly for feeding the larger animals; but few comparatively are fatted on any of these without the addition of turnips of one or other of the varieties formerly mentioned. See Sect. VI. A considerable num¬ ber of cattle are also fatted on the offals of distilleries, when working from corn; a source of supply, the fre¬ quent interruption of which, till of late, was much felt in those situations where the soil does not permit the exten¬ sive cultivation of turnips. It is seldom or never the practice of the best managers Gi to fatten cattle with roots or other winter food on the JJ field during that season, but to confine them to houses or fold-yards, where they are well littered, regulariy fed, not liable to be disturbed, and sheltered from the inclemency of the weather, and where the manure they make is an object of very considerable importance, anc nt f ed :o AGRICULTURE. A^ul- of much greater value than if it were dropped at random t • over a whole field. The age at which cattle are fatted depends upon the lSe ^at'manner in which they have been reared, upon the pro- ^ perties of the breed in regard to a propensity to fatten earlier or later in life, and on the circumstances of their being employed in breeding, in labour, for the dairy, or reared solely for the butcher. In the latter case, the most improved breeds are fit for the shambles when about three years old, and very few of any large breed are kept more than a year longer. As to cows and working oxen, the age of fatting must necessarily be more indefinite ; in most instances the latter are put up to feed after working three years, or in the seventh or eighth year of their age. In general it may be said that the small breeds of cattle are fattened on pastures, though sometimes finished off on a few weeks’ turnips ; and that large cattle, at least in the north, are chiefly fatted in stalls or fold-yards, by means of turnips and the other articles before mentioned, all-pd- Stall-feeding is the most common, and, when judicious- ly conducted, probably the most eligible method in regard to the cattle themselves, the economy of food, and the expense of farm-buildings. The small shed and fold-yard, called a hammel, are used only for the larger breeds ; but they do not seem well calculated for an extensive system of fatting by those who do not breed, but purchase stock every year from different parts. See Chap. I. Sect. II. ttk Cattle, it is well known, have long been the staple pro- ^ duce of Scotland; and since the union of South and North Britain, immense numbers have been carried every year to the feeding pastures and markets of England. But be¬ sides this transportation, so beneficial to both parts of the island, cattle often change their pastures and their owners before leaving Scotland, according to arrangements which, though not conducted with all the uniformity of system, are found to be very advantageous to the individuals con¬ cerned, and ultimately to the public at large. “ The Highland cattle often pass through three differ¬ ent hands, or more, before they come to the butcher. They are improved at every stage by a greater quantity and better quality of food, instead of being suddenly trans¬ ported from poor to rich feeding; and while each succes¬ sive owner applies his produce to the best advantage, and receives a suitable return according to its value, from the 327 years old, having got a liberal allowance of turnips during Agricub theprecedmg winter. ( General Report of Scotland, vol. hi. ture. Notwithstanding the high degree of perfection to which Desido- some breeds of cattle have been brought in England, and rata, the great attention that is paid by the most eminent breeders to every part of their management, several in¬ teresting points are not by any means clearly ascertained. Much certainly remains to be known regarding the nutri¬ ment afforded by different kinds of herbage and roots, the quantity of food consumed by different breeds, in pro¬ portion as well to their weight at the time as to the ratio of theii increase,—and the propriety of preferring large or small animals in any given circumstances. Even with regard to the degree of improvement made by fatting cattle generally, from the consumption of a given weight of roots or herbage, no great accuracy is commonly at¬ tempted; machines for weighing the cattle themselves and their food, from time to time, not being yet in general use in any part of Britain. Sect. III. Sheep. This species being still more than cattle exposed to all Varieties the influences of soil and climate, displays a much greater °f sheep variety in form, size, and general properties. In differentnunierous* counties, though the breed be originally the same, a very perceptible difference is found in all these respects; and there are not unfrequently considerable variations among the flocks of the same district, even those of contiguous farms. Yet in other situations, where rich food is abund¬ antly supplied at all times of the year, sheep have been more highly improved than any other animals; and the breeds most esteemed for the arable land of Britain are in a great measure the creatures of the industry and sa¬ gacity of man. Hardly any two animals are more unlike than the small dun-faced sheep, supposed to be the most ancient of the kind in Britain, and the Leicester or Dish- ley male, whose every point must be exactly formed ac¬ cording to an established model of symmetry and use¬ fulness. The various breeds of sheep, and the modes of manage¬ ment, almost as numerous as these varieties, would re¬ quire a much larger space for their description than it is . - & — me a uiueii icugei spuce ioi meir uescnpuon advance of price, the consumer at last purchases his beef possible to allot to it in a section of this article. cheaper, and of a better quality, than if the cattle had been sent to the shambles from any of the intermediate stages. “ The West Highland cattle make this progress oftener Uuin the larger cattle of the north-eastern counties.

A great many v ,!C p kerdeenshire cattle are bought for the straw- According to one writer (Culley on Live Stock, p. 102), Mode of there are fourteen different breeds of sheep in Great Bri- classifka- tain, all of them sufficiently distinguished by their horns, or by being hornless, by the colour of their faces and legs, and by the length and quality of their wool. To these a later writer adds two varieties more (Dickson’s Practical Agriculture, vol. ii. p. 1135); but a third work, still more recent (Parkinson on Live Stock, vol. i. p. 249), enumerates no fewer than thirty-seven breeds, to each of which are assigned one or more characteristic peculiari¬ ties. This great diversity renders it necessary to decline a particular description of each: perhaps the most eligible mode of classification would be, to consider separately those races which are best adapted to inclosed arable-land; those which occupy green hills, downs, and other tracts of mo¬ derate elevation ; and, finally, such as inhabit the higher hills and mountains. On the first description of land every sort of practicable improvement may be’ effected, varU f i—aic uuugm im uiu straw- though there the carcass has hitherto been the chief ob- wintS ° i SOl^thern count‘es> get a few turnips through ject; on the second the carcass is smaller, but the wool Anr’T aif W and are either driven to England in generally finer,—and it is probably with such sheep that sun* * °r q^ienet^. a*' k°me th0 course of the ensuing the greatest improvements ought to be attempted on the Pow?le^ ^ ie cattle, like the other breeds of the fleece; and on the last division the breeds are necessarily ' aucls, are generally sold to the graziers at three small and hardy, and, in regard to form and general pro- 9 328 AGRICULTURE. Agricul- perties, still almost in a state of nature. The improve- ture. ment of sheep must mainly depend on the circumstances every district, in regard to the food and shelter it af¬ fords them; and it is only where these indispensable re¬ quisites are abundantly provided by nature, or by human industry, that the most skilful management can be suc¬ cessful. The sheep of the rugged heathy mountains of the Highlands of Scotland must ever retain the form, the size, and the habits which the uncontrollable influence of their situation has impressed on them. But this mode of classification is more applicable to the general management adopted on the several sorts of land, than to the present breeds themselves, which are found intermixed in every district, and often even on the same field. We shall therefore in this, as in the two former sections, describe the distinguishing characteristics of the principal breeds as concisely as possible. There is, however, in the case of sheep, as of all the other kinds of live stock, a certain form,—a sort of stand¬ ard established by experience and observation of the best individuals,-—to which it is wished that all the breeds of this species should approach. Mr Culley, to whom we have so often referred, as being by far the most skilful of our writers on live stock, thus describes the best form of a ram Form of “ His head should be fine and small, his nostrils wide the male, ond expanded, his eyes prominent and rather bold or daring, ears thin, his collar full from his breast and shoul¬ ders, but tapering gradually all the way to where the neck and head join, which should be very fine and grace¬ ful, being perfectly free from any coarse leather hanging down; the shoulders broad and full, which must at the same time join so easy to the collar forward, and chine backward, as to leave not the least hollow in either place; the mutton upon his arm, or fore thigh, must come quite to the knee; his legs upright, with a clean, fine bone, being equally clear from superfluous skin and coarse hairy wool from the knee and hough downwards; the breast broad and well forward, which wall keep his fore legs at a proper wideness ; his girth or chest full and deep, and in¬ stead of a hollow behind the shoulders, that part by some called the fore flank should be quite full; the back and loins broad, flat, and straight, from which the ribs must rise with a fine circular arch ; his belly straight, the quar¬ ters long and full, with the mutton quite down to the hough, which should neither stand in nor out; his twist deep, wride, and full, which, with the broad breast, will keep his four legs open and upright; the whole body covered with a thin pelt, and that with fine, bright, soft wrool.. The nearer any breed of sheep comes up to the above description, the nearer they approach towards excellence of form.” (Culley on Live Stock., p. 103.) 1. Breeds. Breeds. The sheep suited to arable land, in addition to such properties as are common in some degree to all the dif¬ ferent breeds, must evidently be distinguished for their quietness and docility,—habits which, though gradually acquired and established by means of careful treatment, are more obvious, and may be more certainly depended on, in some Imeeds than in others. These properties are not only valuable i'or the sake of the fences by which the sheep are confined, but as a proof of the aptitude of the animals to acquire flesh in proportion to the food they consume. 1 he long-wroolled large breeds (the varieties usually pre¬ ferred on good grass-lands) differ much in form and size, and in their fatting quality, as well as in the weight cf their fleeces. The principal are, the Lincoln, the Tce$. .a, , water, and the Bishley or New Leicester'. 3 f In some instances, with the Lincolns in particular, wool'll v seems to be an object paramount even to the carcass; with the breeders of the Leicesters, on the other hand, the carcass has always engaged the greatest attention; but neither form nor fleece separately is a legitimate ground of preference, the most valuable sheep being that which returns, for the food it consumes, the greatest marketable value of produce. The Lincolnshire breed have no horns; the face is white, Lin ISi and the carcass long and thin, the ewes weighing from 14 to 20 lb., and the three-year-old wethers from 20 to 301b. per quarter. They have thick, rough, white legs, bones large, pelts thick, and wool long,—from 10 to 18 inches,— weighing from 8 to 14 lb. per fleece, and covering a slow- feeding, coarse-grained carcass of mutton. This kind of sheep cannot be made fat at an early age, except upon the richest land, such as Romney-marsh, and the rich marshes of Lincolnshire; yet the prodigious weight of wool which is shorn from them every year is an inducement to the occupiers of the marsh-land to give great prices to the breeders for their hogs or yearlings ; and though the buyers must keep them two years more before they get them fit for market, they have three clips of wool in the mean time, which of itself pays them well in those rich marshes. Not only the midland counties, but also Yorkshire, Durham, and Northumberland, can send their long-woolled sheep to market at two years old, fatter in general than Lincolnshire can at three. Yet this breed, and its subvarieties, are spread through many of the Eng¬ lish counties. The Teeswater breed differs from the Lincolnshire in Tee their wool not being so long and heavy; in standing upon'vat higher, though finer-boned legs, supporting a thicker, firmer, heavier carcass, much wider upon their backs and sides ; and in affording a fatter and finer-grained carcass of mutton, the two-year-old wethers weighing from 25 to 35 lb. per quarter. Some particular ones, at four years old, have been fed to 55 lb. and upwards. There is little doubt that the Teeswater sheep were originally bred from the same stock as the Lincolnshire, but, by attending to size rather than to wool, and con¬ stantly pursuing that object, they have become a different variety of the same original breed. “ The present fashionable breed is smaller than the ori¬ ginal species, but they are still considerably larger and fuller of bone than the Midland breed. They bear an ana¬ logy to the short-horned breed of cattle, as those of the Midland counties do to the long-horned. They are not so compact, nor so complete in their form, as the Leices¬ tershire sheep; nevertheless, the excellency of their flesh and fatting quality is not doubted, and their wool still re¬ mains of a superior staple. For the banks of the Tees, or any other rich fat-land country, they may be singularly excellent.” (Marshall’s Yorkshire, vol. ii. p. 221.) Rams of this kind have been employed of late in Northumbei- land and Berwickshire, in crossing ewes of the Leicester breed, but with what success there has not yet been time to dctermiM.r>001fi q0 7qrjrr? n*W3| _n The Diskley or New Leicester breed is distinguishedNe ^ from other long-woolled breeds by their clean heads,ce‘ straight, broad, flat backs, round, barrel-like bodies, very fine small bones, thin pelts, and inclination to make fat at an early age. This last property is most probably owing to the before-specified qualities, and which, from long experience and observation, there is reason to believe, extends through every species of domestic animals. Tim Dishley breed is not only peculiar for its mutton being AGRICULTURE. 329 1- fat, but also for the fineness of the grain and superior t flavour, above all other large long-woolled sheep, so as to ^ ^ fetch nearly as good a price, in many markets, as the mutton of the small Highland and short-woolled breeds. The weight of ewes three or four years old is from 18 to 261b. a quarter, and of wethers two years old from 20 to 30 lb. The wool, on an average, is from 6 to 8 lb. a fleece. See Plate XVI. A fourth hornless variety of long-woolled sheep is the Devo )ire S’ots.) Exm«. )orse iVilta, till' S. ottin;, Devonshire Nots, having white faces and legs, thick necks, narrow backs, and back-bone high; the sides good, legs short, and the bones large; weight much the same as the Leicesters, wool heavier, but coarser. In the same coun¬ ty there is a small breed of long-woolled sheep, known by the name of the Exmoor sheep, from the place where they are chiefly bred. They are horned, with white faces and legs, and peculiarly delicate in bone, neck, and head; but the form of the carcass is not good, being narrow and flat-sided; the weight of the quarters and of the fleece about two-thirds that of the former variety. The shorter-woolled kinds, and such as, from their size and form, seem well suited to hilly and inferior pas¬ tures, are also numerous. Generally speaking, they are too restless for inclosed arable land on the one hand, and not sufficiently hardy for heathy, mountainous districts on the other. To this class belong the breeds of Dorset, Hereford, Sussex, Norfolk, and Cheviot. The Dorsetshire sheep are mostly horned, white-faced, stand upon high, small, white legs, and are long and thin in the carcass. The wethers, three years and a half old, weigh from 16 to 20 lb. a quarter. ^The wool is fine and short, from 3 to 4 lb. a fleece. The mutton is fine-grained and well flavoured. This breed has the peculiar property of producing lambs at almost any period of the year, even so early as Septem¬ ber and October. They are particularly valued for sup¬ plying London and other great towns with house-lamb, which is brought to market by Christmas, or sooner if wanted; and after that a constant and regular supply is kept up all the winter. According to Mr Culley, the Wiltshire sheep are a variety of this breed, which, by attention to size, have got considerably more weight, viz. from 20 to 28 lb. a quarter. These, in general, have no wool upon their bellies, which gives them a very uncouth appearance. “ The variations of this breed are spread through many of the southern counties, as well as many in the west, viz. Gloucestershire, Worcestershire, Herefordshire, &c. 1 hough some of them are very different from the Dorset¬ shire, yet they are, I apprehend, only variations of this breed, by crossing with different tups; and which varia¬ tions continue northward until they are lost amongst those of the Lincolnshire breed.” The Herefordshire sheep are known by their want of horns, and their having white legs and faces, the wool growing close to their eyes. The carcass is tolerably well formed, weighing from 10 to 18 lb. a quarter, and bearing very fine short wool, from H- to 2^ lb. a fleece : the mut¬ ton is excellent. fhe store or keeping sheep of this breed are put into cots at night, winter and summer, and in winter foddered m racks with peas-straw, barley-straw, &c. and in very bad weather with hay. These cots are low buildings, quite co- 'ered over, and made to contain from 100 to 500 sheep, according to the size of the farm or flock kept. The true Herefordshire breed are frequently called Ryeland sheep, rom the land formerly being thought capable of producing no better grain than rye, but which now yields every kind gram. VOL. II See Plate XVI. The South Down sheep are without horns ; they have Agricul- grey faces and legs, fine bones, long small necks ; are low ture. before, high on the shoulder, and light in the fore quarter; the sides are good, and the loin tolerably broad, back- ?”uth bone too high, the thigh full, and twist good. The fleece jL>owns’ is very short and fine, weighing from 21 to 3 lb. The average weight of two-year old wethers is’about 18 lb. per quarter, the mutton fine in the grain, and of an excellent flavour. These sheep have been brought to a high state of improvement by Mr Elman of Glynd, and other intelli¬ gent breeders. They prevail in Sussex, on very dry chalky downs producing short fine herbage. See Plate XVI. In the Norfolk sheep the face is black, horns large and spiral; the carcass is very small, long, thin, and weak, with narrow chines, weighing from 16 to 20 lb. per quarter ; and they have very long dark or grey legs, and large bones. The wool is short and fine, from If to 2 lb. per fleece. This race have a voracious appetite, and a restless and Norfolks. unquiet disposition, which makes it difficult to keep them in any other than the largest sheep-walks or commons. They prevail most in Norfolk and Suffolk, and seem to have been retained solely for the purpose of folding; as it does not appear they have any other good property to re¬ commend them besides being good travellers, for which they seem well adapted, from their very long legs and light lean carcasses. The Cheviot breed are without horns, the head bare and Cheviots, clean, with jaws of a good length, faces and legs white. See Plate XIV. The body is long, but the fore quarters generally want depth in the breast, and breadth both there and on the chine, though in these respects great improve¬ ment has been made of late. They have fine, clean, small¬ boned legs, well covered with wool to the hough. The weight of their carcass, when fat, is from 12 to 18 lb. per quarter; their fleece, which is of a medium length and fineness, weighs about 3 lb. on an average. Though these are the general characters of the pure Cheviot breed, many have grey or dun spots on their faces and legs, especially on the borders of their native district, where they have intermixed with their black-faced neigh¬ bours. On the lower hills, at the extremity of the Cheviot range, they have been frequently crossed with the Leices¬ ters, of which several flocks, originally Cheviot, have now a good deal both of the form and fleece. The best kind of these sheep are certainly a very good mountain stock, where the pasture is mostly green sward, or contains a large portion of that kind of herbage, which is the case with all the hills around Cheviot where those sheep are bred. Large flocks of them have been sent to the Highlands of Scotland, where they have succeeded so well as to encourage the establishment of new colonies ; yet they are by no means so hardy as the heath or black¬ faced kind, which they have in many instances sup¬ planted. Of those races of sheep that range over the mountainous Heath districts of Britain, the most numerous, and the one pro- breed, bably best adapted to such situations, is the Heath breed, distinguished by its large spiral horns, black faces and legs, fierce, wild-looking eyes, and short, firm carcasses covered with long, open, coarse wool. Their xveight is from 10 to 16 lb. a quarter, and they carry from 3 to 41b. of wool each. They are seldom fed until they are three, four, or five years old, when they fatten well, and give excellent mutton and highly flavoured gravy. Different varieties of these sheep are to be found in all the western counties of England and Scotland, from Yorkshire north¬ wards ; and they want nothing but a finer fleece to render them the most valuable upland sheep in Britain. See Plate XV. 2 T 330 AGRICULTURE. Herd- wicks. Agricul- The Herdwick sheep are peculiar to that rocky, moun- ture" tainous district, at the head of the Duddon and Esk rivers, in the county of Cumberland. They are without horns, have speckled faces and legs, wool short, weighing from 2 to 2^- lb. per sheep, which, though coarser than that of any of the other short-woolled breeds, is yet much finer than the wool of the heath sheep. The mountains upon which the Herdwicks are bred, and also the stock itself, have, time immemorial, been farmed out to herds, and from this circumstance their name is derived. Dun-faced. The Dun-faced breed, said to have been imported into Scotland from Denmark or Norway at a very early period, still exists in most of the counties to the north of the Frith of Forth, though only in very small flocks. Of this ancient race there are now several varieties, produced by peculiarities of situation and dilferent modes of manage¬ ment, and by occasional intermixture with other breeds. We may therefore distinguish the sheep of the mainland of Scotland from those of the Hebrides and of the north¬ ern islands of Orkney and Zetland. Hebrides. “ The Hebridean sheep is the smallest animal of its kind. It is of a thin, lank shape, and has usually straight, short horns. The face and legs are white, the tail very short, and the wool of various colours, sometimes of a bluish grey, brown, or deep russet, and sometimes all these co¬ lours meet in the fleece of one animal. Where the pas¬ ture and management are favourable, the wool is very fine, resembling in softness that of Shetland; but in other parts of the same islands the wool is stunted and coarse, the animal sickly and puny, and frequently carries four, or even six horns.” “ The average weight of this poor breed, even when fat, is only 5 or 5^ lb. per quarter, or nearly about 20 lb. per sheep. It is often much less, only amounting to 15 or 16 lb.; and the price of the animal’s carcass, skin and all, is from 10s. to 14s. We have seen fat wedders sold in the Long Island at 7s. a head, and ewes at 5s. or 6s. The quantity of wool which the fleece yields is equally contemptible with the weight of the carcass. It rarely exceeds 1 lb. weight, and is often short of even half that quantity. The quality of the wool is dilferent on different parts of the body; and inattention to separating the fine from the coarse renders the cloth made in the Hebrides very unequal and precarious in its texture. The average value of a fleece of this aboriginal Hebridean breed is from 8d. to Is. sterling. From this account it is plain that the breed in question has every chance of being speedily extirpated.” (Macdonald’s Deport of the He¬ brides, p. 447.) Zetland. In the Zetland Isles it would appear that there are two varieties; one of which is considered to be the native race, and carries very fine wool; but the number of these is much diminished, and in some places they have been entirely supplanted by foreign breeds. The other variety carries coarse wool above, and soft, fine wool below. “ They have three different successions of wool yearly, two of which resemble long hair more than wool, and are termed by the common people fors and scudda. When the wool begins to loosen in the roots, which generally happens about the month of February, the hairs or scudda spring up; and when the wool is carefully plucked off, the tough hairs continue fast, until the new wool grows up about a quarter of an inch in length, when they gra¬ dually wear off; and when the new fleece has acquired about two months’ growth, the rough hairs, termed fors, spring up, and keep root, until the proper season for pulling it arrives, when it is plucked off along with the t wool, and separated from it at dressing the fleece, by an^L operation called forsing. The scuMa remains upon the skin of the animal, as if it were a thick coat; a fence against the inclemency of the seasons, which provident nature has furnished for supplying the want of the fleece. “ The wool is of various colours. The silver grey is thought to be the finest; but the black, the white, the mourat or brown, is very little inferior ; though the pure white is certainly the most valuable for all the finer pur¬ poses in which combing wool can be used.”1 In the northern part of Kincardineshire, as well as in Mai 4 most other of the northern counties, there is still a rem¬ nant of this ancient race, distinguished by the yellow co¬ lour of the face and legs, and by the dishevelled texture of the fleece, which consists in part of coarse, and in part of remarkably fine wool. Their average weight in that county is from 7 to 9 lb. a quarter, and the mutton is re¬ markably delicate and highly flavoured. {Kincardineshm Deport, p. 385.) . -A : The last variety we shall mention is the Spanish orMeijs, Merino breed, bearing the finest wool of the sheep spe¬ cies. The males usually have horns of a middle size, but the females are frequently without horns; the faces and legs are white, the legs rather long, but the bones fine. The average weight per quarter of a tolerably fat ram is about 17 lb., and that of ewes about 11 lb. The shape of this race is far from being perfect, according to the ideas of English breeders, with whom symmetry of proportion constitutes a principal criterion of excellence. The throatiness, or pendulous skin beneath the throat, which is usually accompanied with a sinking or hollow in the neck, presents a most oflensive appearance, though it is much esteemed in Spain, as denoting both a tendency to fine wool and a heavy fleece. Yet the Spanish sheep are level on the back and behind the shoulders; and Lord Somerville has proved, that there is no reason to conclude that deformity in shape is in any degree necessary to the production of fine wool. The fleece of the Merino sheep weighs upon an ave-Fk rage from 3 to 5 lb. In colour it is unlike that of any English breed. There is on the surface of the best Spanish fleeces a dark brown tinge, approaching almost to a black, which is formed by dust adhering to the greasy properties of its pile; and the contrast between this tinge and the rich white colour below, as well as that rosy hue of the skin which denotes high proof, at first sight excites much surprise. The harder the fleece is, the more it resists any external pressure of the hand, the more close and fine will be the wool. Here and there indeed a fine pile may be found in an open fleece, though this occurs but rarely. Nothing, however, has tended to render the Merino sheep more unsightly to the English eye than the large tuft of wool which covers the head: it is of a very inferior quality, and classes with what is produced on the hind legs; on which account it does not sort with any of the three qualities, viz. Dejinos or prime, Finos or second best, and Terceros, the inferior sort, and consequently is never exported from Spain. The Spanish flocks which yield fine wool are sometimes Tra ^ distinguished by the appellation of Trashurmnte, on ac-tk count of their travelling from one end of the kingdom to the other, though there are flocks that never travel, with wool equally fine. They are wintered in Estremadura 1 Sir John Sinclair o« the Different Breeds of Sheep, &c—Appendix, No. 4. (Account of the Shetland Sheep, by Thomas Johnston, p. 79.) AGRICULTURE. J. and other warm provinces in the south; and during the summer months they graze on the northern mountains of Castile, Leon, and Asturias. Merinos were first brought into England in 1788, but did not excite much interest before his Majesty’s sales, which began in 1804 The desirable object of spreading them widely over the country, and subjecting them to the experiments of the most eminent professional breeders, was greatly promoted by the institution of the Merino Society in 1811; which soon comprehended some of the greatest landholders and the most eminent breeders in the kingdom. See Plate XVII. It seems to be generally admitted, however, that the wool is somewhat deteriorated since the sheep were brought to this country, whatever improvement may have been made on the carcass. Valuable as the fleece is, our breeders still find that the carcass is the principal object; and their management must therefore be conducted ra¬ ther with a view to the supply of the butcher than the clothier. There may be something in our climate unfa¬ vourable to the growth of fine wool; but the principal cause will probably be found in the mode of feeding, which is in every respect so superior to what they expe¬ rience in Spain and other parts of the Continent. As a means of improving the wool of our own breeds, it may often be beneficial to cross with the Merinos; but as a separate and distinct race, it is hardly to be expected that they will ever establish themselves upon an exten¬ sive scale in this country. 2. Breeding and Rearing. A greater degree of perfection has been attained in the breeding of sheep than in any other species of live stock; and in this branch, in particular, the breeders of England stand higher than those of any other country. We have therefore purposely deferred the observations which it seems necessary to offer on the different systems of breeding, to this part of our article; though they may aPply generally to other species of animals as well as to sheep. The males and females possessed of the properties the breeder wishes to acquire, may be, 1. of the same family; •3. of the same race, but of different families; or, 3. of different races. The first method is called breeding in-and-in. This re¬ quires that animals of the nearest relationship should be put together, and is supposed by many to produce a ten¬ der, diminutive, and unhealthy progeny. But if a male and female, got by the same sire, were never to be put to- k°wever excellent they might be, a stock that should by any means have become better than others could not be long preserved from deterioration by strangers, nor could it be still further improved by selection. By hreedmg in the same family for a great many years, Mr nakewell succeeded in raising his sheep to a degree of perfection which no other fattening animal ever attained in any age or country. It is certainly,” says Mr Gulley, one of the most emi¬ nent of hiS disciples, “ from the best males and females that Uie best breeds can be obtained or preserved.”—“ When } ou can no longer find better males than your own, then by Hi means breed from them, whether horses, neat-cattle, ^ icep, &c.; for the same rule holds good through every -pccms of domestic animals; but upon no account attempt /Pj 0r cross from worse than your own; for that enp1 e act'ng in contradiction to common sense, experi- heartl*' ™at ^^-established rule, ‘ That best only can nl r •0r’ which is a particular case of a more gene- ral rule> ‘ That like begets like.' ” 331 This reasoning is opposed by others, who, however, Agricul- rather deny the premises than dispute the conclusion, ture. it has been contended that there never “did exist atV animal without some defect m constitution, in form or in some other essential qualitythat “ this defect, however small it may be at first, will increase in every succeedimr generation, and at last predominate to such a degree as to render the breed of little value.”—“ Mr Bakewell very properly considered a propensity to get fat as the first quality in an animal destined to be the food of man. His successors have carried his principle too far; their stock are become small in size, and tender, produce little wool, and are bad breeders.” (Sebright on improving the Breeds of Domestic Animals, p. 11, 14) It is admitted, however, that breeding in-and-in will have the same effect in strengthening the good as the bad properties, and may be beneficial if not carried too far, particularly in fixing any variety that may be thought valuable. And again, the same writer observes, “ There may be families so nearly perfect as to go through several generations without sustaining much injury from having been bred in-and-in; but a good judge would upon ex¬ amination point out by what they must ultimately fail, as a mechanic could discover the weakest part of a machine before it gave way.” (Sebright on improving the Breeds of Domestic Animals, p. 12.) “ But one of the most conclusive arguments that cross¬ ing with a different stock is not necessary to secure size, hardiness, &c., is the breed of wild cattle in Chillingham park, in the county of Northumberland. It is well known these cattle have been confined in this park for several hundred years, without any intermixture, and are perhaps Aid purest breed of cattle of any in the kingdom. From their situation and uncontrolled state, they must indisput¬ ably have bred from the nearest affinities in every possi¬ ble degree; yet we find these cattle exceedingly hardy, healthy, and well formed, and their size, as well as colour, and many other particulars and peculiarities, the same as they were five hundred years since.” (Gulley on Live Stock, p. 10.) Notwithstanding all this, it must be admitted that Crossing there is a great diversity of opinion among intelligent men families of respecting the expediency of this mode of breeding, andthe sarae in most instances, perhaps, a pretty strong prejudicerace‘ against it. The most common practice therefore is, to breed from different families of the same race. When these have been for some time established in a variety of situations, and have had some slight shades of difference impressed upon them by the influence of different soils and treatment, it is found advantageous to interchange the males, for the purpose of strengthening the excellen¬ cies or remedying the defects of each family. Of this advantage Mr Bakewell could not avail himself; but it has been very generally attended to by his successors. Mr Gulley for many years continued to hire his rams from Mr Bakewell, at the very time that other breeders were paying a liberal price for the use of his own; and the very same practice is followed by the most skilful breeders at present. In large concerns, two or more streams of blood may be kept distinct for several generations, and occasion¬ ally intermixed with the happiest effects, by a judicious breeder, without having recourse to other flocks. The only other method is, by crossing two distinct Crossing breeds or races, one of which possesses the properties different which it is wished to acquire, or is free from the defects ^ree^s- which it is desirable to remove. This measure can only be recommended when neither of the former methods will answer the purpose. The very distinction of breeds implies a considerable difference among animals in seve- 332 AGRICULTURE. Agricul¬ ture. General rules. Breeding of males. Letting. Season of breeding. Manage¬ ment of hill sheep ral respects; and although the desirable property be ob¬ tained, it may be accompanied by such others as are by no means advantageous to a race destined to occupy a situation which had excluded that property from one of its parents. To cross any mountain breed with Leicester rams, for example, with a view to obtain a propensity to fatten at an early age, would be attended with an enlarge¬ ment of size, which the mountain pasture could not sup¬ port ; and the progeny would be a mongrel race, not suit¬ ed to the pastures of either of the parent breeds. If the object be to obtain an enlargement of size, as well as a propensity to fatten, as is the case when Cheviot ewes are crossed with Leicester rams, the progeny will not prosper on the hilly pastures of their dams, and will be equally unprofitable on the better pastures of their sires. But the offspring of this cross succeeds well on those in¬ termediate situations on the skirts of the Cheviot hills, where, though the summer pasture is not rich, there is a portion of low land for producing clover and turnips. In every case where the enlargement of the carcass is the object, the cross breed must be better fed than its smaller parent. The size of the parents should also be but little disproportioned at first; and when some increase has been produced, one or more crosses afterwards may raise the breed to the required size. With these precau¬ tions, there is little reason to fear disappointment, provid¬ ed both parents are well formed. {General Report of Scotland, vol. iii. p. 14—18.) The breeding of males, still more in this species than in cattle, has long been a separate pursuit; and there are few flocks skilfully managed in which it is not still the practice to have recourse occasionally to rams hired at a high price from those men whose chief attention is de¬ voted to this branch of business. These rams are shown for hire, at certain times and places during the summer, where every one may select such as promise to maintain or improve the particular state of his flock, and at such prices as his means and experience may justify. Iwo or more individuals frequently join together in the hire of one ram, to which they put the best of their ewes, for the pur¬ pose of obtaining superior males for the future service of the rest of their flocks; and in particular cases, when the owner of the ram does not choose to part with him, even for a season, ewes are sent to him to be covered at a certain price per head, superior animals of this class being very seldom sold altogether. Much as this mode of doing business has been reprobated as a monopoly, and much as there may sometimes be of deception in making up rams for these shows, all intelligent practical men must agree that there can be no better method of remunerating emi¬ nent breeders, and of spreading their improvements most widely, in the shortest period, and at the least possible ex¬ pense. A single ram thus communicates its valuable pro¬ perties to a number of flocks, often in distant parts of the country, without distracting the attention of ordinary breeders from their other pursuits. It is a striking in¬ stance of the division of labour, which in this, as in other branches, has been productive of the most beneficial re¬ sults to all concerned, and to the community at large. Bams and ewes are allowed to copulate earlier or later, according to the prospect of food for their young at the period of parturition,—usually in October and the early part of November; and as the time of gestation with sheep is twenty-one weeks, the lambs are accordingly dropped in March or April. The management of the Leicester breed, equally applicable to all the varieties kept on low arable land, having been detailed at some length in the works already referred to, we shall here give a condensed view of the best practices in regard to the stocks of hilly or mountainous districts, chiefly collected from the skil- Ag i ful management of the breeders of the Cheviot sheep ti on the borders of South and North Britain. 1. In November the rams are put to the ewes a little Cop earlier or later, according to the prospect of spring f'ood,ticii but seldom before the 8th or 10th of that month. The number of rams required is greater or less, according to the extent of the pasture, and their own age and condition. If the ewes are not spread over an extensive tract, one ram to sixty ewes is generally sufficient. It is usually thought advisable to separate the gimmers (sheep once shorn) from the older ewes, and to send the rams to the latter eight or ten days before they are admitted to the former. Notwithstanding this precaution, which retards their lambing season till the spring is farther advanced, ewes which bring their first lamb when two years old, the common period on the best hill farms,, are often very bad nurses, and in a late spring lose a great many of their lambs, unless they are put into good condition with turnip before lambing, and get early grass afterwards. This se¬ paration, and difference in the time of admitting the rams to the ewes and gimmers, should therefore be always at¬ tended to. 2. When a farm under this description of stock hastheSelt convenience of a few good inclosures, still more minute of r attention is paid by skilful managers. It is not sufficientan(' that the rams are carefully selected from perhaps doublemiU the number; the ewes also are drawn out and assorted, and such a ram appropriated to each lot as possesses the properties in form or fleece in which the ewes are defi¬ cient. In other cases, the best ram and the best lot of ewes are put together. When neither of these arrange¬ ments can be adopted, owing to the want of inclosures, it is the practice to send the best rams to the ewes for a few days at first, and those of an inferior description after¬ wards. In every case, when the farmer employs rams of his own flock, he is careful to have a few of his best ewes covered by a well-formed and fine-woolled ram, for the purpose of obtaining a number of good ram-lambs, for preserving or improving the character of his stock. 3. The stock through winter, in a mere breeding farm, Sq consists of ewes and gimmers which should have lambs buff spring, ewe-lambs or hogs, and a few young and old1-1 rams. All these are sometimes allowed to pasture pro¬ miscuously, but on the farms around Cheviot the ewes and ewe-hogs are kept separate, and the latter are either put on rough pastures which have been lightly stocked in the latter end of summer, or get a few turnips once a day, in addition to the femains of their summer pasture. The most effectual preventive of the desolating distempers to which sheep of this age are liable is turnips; and though they should never taste them after¬ wards, a small quantity is frequently given them during their first winter. After the rams have been separated from the ewes, they are usually indulged with the same feeding as the hogs. 4. The ewes, during winter, are seldom allowed any other food than what their summer pasture affords, except that a small part of it may sometimes be but lightly eaten, and reserved as a resource against severe storms. When these occur, however, as they often do in the Cheviot dis¬ trict, there is little dependence on any other food than hay. When the snow is so deep as completely to cover the herbage, about two stones avoirdupois of hay are allow¬ ed to a score of sheep daily, and it is laid down morning and evening in small parcels on any sheltered spot neai the houses, or under the shelter of stelh or clumps o trees, on different parts of the farm. i 5. In March, the ewes, at least the gimmers or young AGRICULTURE. Agiml- ewes, are commonly allowed a few turnips once a day, on into a fold, and all the male lambs are castrated excent v ;• farms on which there is any extent of arable land, which few of the best, reserved for rams. The ewe-lambs are new \jr ^ are either carted to their pastures, or eaten on the ground 333 Udd* lockii- Laratig. Agricul- , - lambs are never ture- spayed, it is advisable to perform this severe but necessary operation when the lambs are but a few days old, if the weather will permit, instead of delaying till the end of the lambing season, as is still the case in some instances. 10. lowards the end of the lambing season the ewesLdBfe that have not yet dropped lambs are separated from the Iambs, flock and kept by themselves, that they may be more un¬ der the eye of the shepherd, than if scattered over all the pasture. It is desirable to allow them finer grass for a few weeks after lambing, that their lambs may come to be nearly equal to the rest of the flock when weaned; or, if they are too late for this, that they may get ready for the butcher by the month of August, beyond which period the ewes must be much injured by suckling them. 11. When the wool has risen sufficiently (and the pro- Washing, per time is easily known by the appearance of a new growth), the barren sheep are brought to the washing- pool. Sometimes they are hand-washed by men, who stand in the pool and have the sheep forced towards them singly; but more commonly the Cheviot sheep, especially if the flock be numerous, are compelled to leap into the pool in a body for three or four times successively; and it is desirable that they should have room to swim a little, and come out on a green low bank on the opposite side. After being washed, the sheep are preserved as far as possible from rubbing against earthen dikes or banks, and from lying down on any dirty spot which might soil their wool. There are two methods of shearing; in the Shearing, one, the operator sits on the floor or on the ground, lays the sheep on its back between his knees, begins with the belly, and afterwards, having tied the animal’s legs, pro¬ ceeds very expeditiously, at the rate of four or five sheep in the hour, or from forty to fifty a day. This is the com¬ mon method of shearing Cheviot sheep. In the other, which is a much more perfect method, the shearer raises the animal on its buttocks, and, beginning at the neck, clips in a circular direction from the belly to the back¬ bone, for some time with one hand, and then on the opposite side with the other. The fleeces are neatly lapped up, after any filthy spots have been cut off, the shorn side out¬ wards, beginning at the breech-wool, and using that of the neck and shoulders as a bandage. Before the shorn sheep are turned out to pasture, they are marked, commonly with the owner’s initials, by a stamp, or boost in provincial language, dipped in tar heated to a thin fluid state ; and it is not unusual to place this mark on different parts of the body, according to the sheep’s age. 12. The principal markets for Cheviot lambs in the Weaning south of Scotland are held in the month of July, the first lambs, on the fifth of July; so that the lambs may commonly be weaned when about three months old, and sometimes sooner. When the ewes are gathered to be washed or shorn, the ewe-lambs to be kept for supplying the place of the old ewes, annually sold, are stamped in the same way as the ewes. The store-lambs are sent to some clean by bringing the sheep to the turnip-field through the night. A part of the field, in the latter case, is cut off by nets or by hurdles, which inclose the sheep in the same way as if they were intended for fattening. When they are ready to drop their lambs, they are no longer kept on the turnip-field, but get what turnips may be left, on their pastures. It is seldom, however, that the turnips last so long, though it is desirable to have a few remaining, to be given to the weakest ewes, or to such as have twins, in a separate inclosure. 6. A few days before the time of lambing, the ewes are collected for the purpose of being udder-locked. The sheep are raised upon their buttocks, their backs next to the operator, who then bends forward and plucks off the locks of wool growing on or near the udders, for the purpose of giving free access to the expected lambs. At the same time he ascertains the condition of the ewes, and marks such as do not appear to be in lamb, which may then be separated from the others. This operation is not with¬ out danger, and several premature births are usually the consequence. It is therefore not so general a practice as it was formerly, though still a common one on many, if not on most farms. 7. On those farms where the hogs have been allowed to pasture promiscuously with the ewes, which is seldom permitted on the Cheviot hills, a separation should always take place at the commencement of the lambing season ; and the lowest and finest part of the pasture ought to be exclusively appropriated to the nursing ewes. 8. The ewes begin to drop their lambs in the first or second week of April, according to the time at which the rams were admitted; and such as have twins generally lamb among the first of the flock. At this season the most constant attention is indispensable on the part of the shepherds, both to the ewes in labour and to the newly dropped lambs. Though the Cheviot ewes are not so liable to losses in parturition as some larger breeds which are in higher condition, and though they make good nurses, unless they are very lean, and their food scanty, yet among a large flock there are always a number that need assistance in lambing, and in a late spring not a few that have not milk sufficient for their lambs, particularly among the gimmers or young ewes. A careful shepherd at this time always carries a bottle of milk along with him, which he drops from his own mouth into that of the lamb that may need it,—brings the ewes that have little milk to a better pasture, or to turnips,—and confines such as have forsaken their lambs in a small pen, or barrack as it is called, temporarily erected in some part of the farm-stead- mg. The same confinement is necessary when it is wish¬ ed to make a ewe that has lost her own lamb nurse that of another ewe that has had twins, or that has perished in ambing, or is from any other cause incapable of rearing her lamb. The ewe, after being shut up for a few hours ... "lt'1 stranger lamb, usually admits it to the teat, and grassy pasture for a few weeks ; and where the farm does e\er af ter treats it as her own; though sometimes a little deception is necessary, such as covering the stranger with t ie skin of her own lamb. At this important season, an inclosure early grass, near the shepherd’s cottage, is of vast advantage. Thither he carries the ewes and tw ins, such as have little milk,—those that have been not afford this accommodation, they must be summered, as it is called, at a distance. Several farms near Cheviot, and on the Lammermuir hills in Berwickshire, are appro¬ priated to this purpose, the owner of the lambs paying so much a head for six or eight weeks. In the mean time the ewe-hogs, or gimmers, as they are denominated after ktr:'). induced to adopt another’s offspring,—and, generally, all shearing, have joined the ewe stock; and the lambs, when iat need to be frequently inspected, and are in want of brought home, go to the pasture which they had occupied, etter treatment than the rest of the flock. Wherever they may be kept in winter, it is always desir- • soon as the weather is favourable, after a consid- able to allow them a few turnips, along with a full bite of erable number of the ewes have lambed, they are collected coarse herbage. 334 AGRICULTURE. Agricul¬ ture. Milking ewes. Drafting out old Salving. 13. When the lambs had been separated from the ewes, it was formerly the practice to milk the ewes for six or eight weeks or more; and this most objectionable manage¬ ment is still continued by several farmers. The most skilful store-masters, however, have either laid aside milk¬ ing, unless for a few days, or have shortened the period to two or three weeks. The value of the milk for eight weeks will not exceed from one shilling to one shilling and sixpence a head, and the sheep are injured to at least three times that amount, independent of accidents at the milking fold. The cream is separated from the ewe-milk, and made into butter for smearing, and the milk itself mixed with cow-milk, and converted into cheese. 14. The next object of attention is the drafting of the old ewes to be sold in September or October. Their age, on the lower hills, is usually four years and a half, or they are disposed of after having reared lambs for three years. In some situations they are kept on till a year older ; but when they are purchased, as they usually are, to be kept another year on lower grounds, it is commonly for the in¬ terest of the store-farmer to sell them when still in their full vigour. Skilful managers do not content themselves with drafting them merely according to age ; and as there is no disadvantage in keeping a few of the best another year, they take this opportunity of getting rid of such of the flock of other ages as are not of good shapes, or are otherwise objectionable. As soon as the ewes to be dis¬ posed of are drawn from the flock, they are kept by them¬ selves on better pasture, if the circumstances of the farm will admit of it. Sometimes they are carried on till they are fattened, and turnips are often purchased for them at a distance. When this is the case, it is not thought ad¬ visable to keep them longer than till between Christmas and Candlemas, as an old ewe does not improve like a wether in the spring months. 15. The last operation of the season is salving or smearing, which is usually performed towards the end of October or beginning of November, before the rams are sent to the ewes. The most common materials are butter and tar, mixed in different proportions ; a greater propor¬ tion of tar being employed for the hogs or young sheep than for the older ones. The butter is slowly melted and poured upon the tar, and the mixture is constantly stirred till it becomes cool enough for use. The wool is accurately parted into rows from the head to the tail of the animal, and the salve is carefully spread upon the skin with the point of the finger, at the bottom of each row. The ob¬ ject of this operation is to destroy vermin, to prevent cu¬ taneous diseases, and to promote the warmth and comfort of the animal during the storms of the ensuing winter. It is not necessary with sheep kept on low grounds, and well fed during winter ; and it may be occasionally omitted for one season, particularly with old sheep, without material injury; but notwithstanding the ridicule that speculative writers have attempted to throw upon the practice, it is almost universally considered necessary and beneficial, on high exposed situations, by the store-farmers of the border hills. ( General Report of Scotland, vol. iii.) Inconsequence of the great depression of late in the price of tarred wool, however, various attempts have been made to use in its stead other mixtures, which are laid on the sheep either in a liquid form, such as tobacco liquor and turpentine, or of the consistency of a salve, which is composed of oil and butter or tallow, with a mixture of turpentine. There has not been sufficient experience to ascertain whether tar can be altogether dispensed with in the case of the moun¬ tain flocks; but in general it is now used much more spar¬ ingly than formerly. Besides those general rules of management which are applicable, with slight modifications, to all the numerous A breeds of sheep, there are practices more or less exten- i sively followed in particular districts, or with particular^ v breeds, the most important of which are cotting and fold¬ ing. In describing the Herefordshire sheep, the practice of keeping them in cots through the night has been already noticed ; and a similar one is followed in some parts of the Highlands of Scotland with the small dun-faced flocks of that district. Folding is adopted as a regular part of the system off'ol management in several counties of England, for the pur¬ pose of turning the dung of the animals to the best account in promoting the fertility of their arable land. The same thing has been done to a small extent in Scotland, but it forms no part of general management there, and is con¬ fined to those situations where, from the want of inclosures, it is necessary to the protection of the crops, and to small patches of what is still in the ancient state of outfield, as a preparation for corn. The sheep best adapted to the fold are those of theFol more active short-woolled varieties, such as the Norfolk, bra Wiltshire, and South Down breeds ; the heavy long-wool- led kinds being less hardy, and some of them, as the Lei- cesters, much too valuable for a mode of treatment that converts them into dung carriers. The following calcu¬ lation will show, that though in open lands the practice may be in some cases tolerated on the ground of con- veniency or expediency, it can possess no recommenda¬ tion as a profitable mode of management in other circum¬ stances; and the best farmers, indeed, from Bakewell, who used to say that it was robbing Peter to pay Paul, down to the present time, agree in reprobating sheep-fold¬ ing as a branch of general management. “ This morning (September 22d, 1780) measured a sheep-fold set out for 600 sheep, consisting of ewes, wed- tiers, and grown lambs. It measures 8 by 5^ rods, which is somewhat more than 7 rods to 100, or 2 yards to a sheep.” “ August 29, 1781. Last autumn made an accurate experiment, on a large scale, with different manures for wheat, on a sandy loam, summer-fallowed. “ Part of an 18 acre piece was manured with 15 or 16 loads of tolerably good farm-yard dung an acre, part with three chaldrons of lime an acre; the rest folded upon with sheep twice; the first time at the rate of 600 sheep to a quarter of an acre (as in first Minute), the second time thinner. “ In winter and spring the dung kept the lead; and now, at harvest, it has produced the greatest burden of straw. “ The sheep-fold kept a steady pace from seedtime to harvest, and is now evidently the best corned and the cleanest crop. “ The lime, in winter and spring, made a poor appear¬ ance ; but after some showers in summer, it flourished much, and is now a tolerable crop, not less, I apprehend, than three quarters an acre. “ From these data, the value of a sheep-fold, in this case, may be calculated. “ It appears from the first Minute that 100 sheep ma¬ nured seven square rods daily. But the second folding was thinner,—suppose nine rods; this is, on a par of the two foldings, eight rods a day each folding. “ The dung could not be worth less than half-a-crown a load, and the carriage and spreading ten shillings an acre ; together, fifty shillings an acre ; which quantity of land the hundred sheep teathed twice over in forty days. “ Supposing them to be folded the year round, they Va! would at this rate fold nine acres annually; which, atma1 50s. an acre, is L.22. 10s. a hundred, or 4s. 6d. a head. “ In some parts of the island the same quantity of AGRICULTURE. A jl. dung would be worth L.5 an acre, which would raise the tu value of the teathe to nine shillings a head ; which, at two- ✓'mw'pence a ^ead a week, is more than the whole year’s keep of the sheep. “ It does not follow, however, that all lands would have received equal benefit with the piece in consideration, which perhaps had not been folded upon for many years, perhaps never before; and sheep-fold, like other manures, may become less efficacious the longer it is used on a given piece of land.” (Marshall’s Rural Economy of Norfolk, vol. ii. p. 29.) It must readily occur, that to fold on land in tillage all the year is nearly impracticable ; and that where it could he done, the manure would be greatly diminished in value from rain and snow, to say nothing of the injury to the sheep themselves; so that the estimate of four shillings and sixpence, or nine shillings a head, is evidently in the extreme. j ns According to the experience of Mr Arthur Young folik- (Farmers Kalendar), the same land will maintain one- fourth more stock when the animals are allowed to de¬ pasture at liberty, than when confined during the night in folds. The injury to the stock themselves, though it is not easy to mention its precise amount with any degree of accuracy, cannot well be doubted, at least in thecase of the larger and less active breeds, when it is considered that they are driven twice a day, sometimes for a distance of two or even three miles, and that their hours of feeding and rest are in a great measure controlled by the shep¬ herd and his boy. “ When they are kept in numerous parcels, it is not only driving to and from the fold that affects them, but they are in fact driving about in a sort of march all day long, when the strongest have too great an advantage, and the flock divides into the head and tail of it, by which means one part of them must trample the food to be eaten by another. All this proves the very re¬ verse of their remaining perfectly quiet in small parcels.” Another writer observes, that “ were the pasture sheep of Lincolnshire to be got into a fold once a week, and only caught one by one and put out again immediately, it would prevent their becoming fat.” (Parkinson on Live Stock, vol. i. p. 367.) The only sort of folding ever adopt¬ ed to any extent by the best breeders is on turnips, clovers, tares, and other rich food, where the sheep feed at their ease, and manure the land at the same time, jp- Another mode of management somewhat akin to this S' Practice, and which is similar to one that has been warm¬ ly recommended in a recent publication (Sir J. Sinclair’s usbandry of Scotland), as if it had been formerly un¬ known, is described and commented on by Mr Young as (mows:—“ This practice is, to confine them at night in a sheep-yard, well and regularly littered with straw, stubble, and fern ; by which means you keep your flock warm and Healthy in bad seasons, and at the same time raise a sur- pibmg quantity of dung,—so great a quantity, if you have p enty of litter, that the profit will be better than folding on the land. A great improvement in this method would o, giving the sheep all their food (except their pasture) ■n such yard, viz. hay and turnips, for which purpose they nay be brought up not only at night, but also at noon, to e baited ; but if their pasture be at a distance, they should len, instead of baiting at noon, come to the yard earlier ie evening, and go out later in the morning. This is piactice that cannot be too much recommended; for so wilW a ,lodS,ng is a g^at matter to young lambs, and ale k611] mu.c^ forward their growth : the sheep will som 6 £.ood health ; and, what is a point of con- vervtnCe t0 a^- faFms’ ^le quality of dung raised will be y great. If this method is pursued through the months 335 nWe,CTrf.r’ Ja,nnTT’ Feb™ry> March, and April, with Agricl. plenty ofhtter, 100 sheep will make a dunghill of at least lore. 60 loads of excellent stuff, which will amply manure twov^v'^-> acres of land ; whereas 100 sheep folded (supposing the grass dry enough) will not in that time equally manure an acre.” That such a method may be advantageous in particular cases, it would be rash to deny; but, generally, it is not advisable, either on account of the sheep, or any alleged advantage from the manure they make. As to the sheep, this driving and confinement, especially in summer, would be just as hurtful as folding them in the common way; anti it has been found that their wool was much injured by the broken litter mixing with the fleece, in a manner not to be easily separated; besides, now that it is the great object of every skilful breeder to accelerate the ma¬ turity of his sheep, as well as other live stock,—among other means, by leaving them to feed at their ease, and, if circumstances permit, in small parcels,—such a practice as this can never be admissible in their management. And with regard to manure, there can be no difficulty in converting into it any quantity of straw, stubble, and fern, by cattle fed in fold-yards, on green herbage in summer, and turnips or other succulent food in winter; while the soil, especially if it be of a light, porous quality, is great¬ ly benefited, both by the dung and treading of sheep al¬ lowed to consume the remainder of both sorts of food on the ground. It is true that the dung of sheep has been generally supposed to be more valuable than that of cattle; but accurate experiments have not been made to determine the difference in this respect among these and other polygastric animals. The greater improvement of pastures by sheep is probably owing as much to their mode of feeding as to the richer quality of their dung. On the subject of breeding and rearing sheep, it would Dr Parry’s be improper to omit noticing the judicious and successful experi- experiments of Dr Parry and others, in crossing our native ments' breeds with the Merino race, having for their object to improve the carcass without deteriorating the quality of the wool. The land on which Dr Parry began his experiments was high, of a thin staple, dry, unsheltered, and conse¬ quently unproductive; and as his other avocations did not permit him constantly to superintend its management, he became impressed with the belief that its most profit¬ able application would be to a breed of sheep, the return of which should chiefly depend on the fleece; and such a breed he proposed to obtain by means of crossing with the Merinos, some of which had then (1792) been recently imported by the king. Accordingly he fixed, as the basis of his experiments, on the Ryeland breed, which has long been reputed as affording some of the finest wool in the island. Dr Parry objects to washing the wool on the sheep’s Lavatories, back before shearing. The fleece is so thick, that when thoroughly soaked with water it is very long in drying; and if the weather prove wet and cold, the sheep are evi¬ dently much incommoded. He thei’efore recommends public lavatories, as in Spain, for cleansing the wool after being shorn. His sheep are shorn about the second week of June ; and if the weather be then unfavourable, he thinks it would be fit to house them for two or three nights or Housing, days after the operation. The lambs have been always Shearing shorn unwashed at the end of July or beginning of Au-lambs, gust, without appearing to have suffered any injury. The fleece of such lambs as are rather coarse, he thinks, should be always shorn, as he has shown that the wool of many of this race is comparatively coarse, even in those indivi¬ duals in which the fleeces afterwards acquire the finest 336 AGRICULTURE. Agricul¬ ture. Successive crosses. quality. The finer-fleeced lambs may be left unshorn, as it has been proved that no loss is sustained by delaying shearing them till the usual period. The effects of successive crosses, both on the form and the fleece of the progeny, are ably illustrated by this ac¬ curate experimentalist. With regard to the former, Dr Parry candidly declares that his only object, the improve¬ ment of the fleece, did not allow him to give attention to the best forms in selecting his breeders; but, notwith¬ standing this, “ my sheep,” he observes, “ are in general shorter in the legs and necks, have smaller bones, a rounder barrel, a wider loin, and consequently a better hind quarter, than any pure Merinos I have happened to see, except one particular ram belonging to Lord Somer¬ ville.” This change he attributes to the female or Rye- land blood, which, in forming the progeny, acts most on the carcass, while that of the male or Merino chiefly af¬ fects the skin and fleece. According to the general opinion of cultivators on the Continent, any breed of ewes, however coarse and long in the fleece, will, on the fourth cross of the Merino ram, give progeny with short wool equal to the Spanish. Of the truth of this proposition, however, Dr Parry justly ex¬ presses some doubts, derived from his own experience and that of others. But it is certain, he adds, that one cross more will, in most cases, effect the desired purpose. “ If we suppose the result of the admixture of the blood of the Merino ram to be always in an exact arith¬ metical proportion, and state the native blood in the ewe as 64, then the first cross would give ff of the Merino ; the second, ; the third, ; the fourth, ; the fifth, ; the sixth, ||; and so on. In other words, the first cross would leave 32 parts in 64, or half of the English qua¬ lity ; the second 16 parts, or one fourth ; the third 8 parts, or one eighth ; the fourth 4 parts, or one sixteenth ; the fifth 2 parts, or one thirty-second; the sixth 1 part, or one sixty-fourth ; and so on. “ Now, if the filament of the Wiltshire or any other coarse wool be in diameter double that of the Ryeland, it is obvious that, according to the above statement, it would require exactly one cross more to bring the hybrid wool of the former to the same fineness as that of the latter. This, I believe, very exactly corresponds with the fact. The difference between one eighth and one six¬ teenth is very considerable, and must certainly be easily perceived, both by a good microscope, and in the cloth which is manufactured from such wool. In the latter method it certainly has been perceived; but I have hi¬ therto had no opportunity of trying the difference by the former. The fifth cross, as I have before observed, brings the Merino-Wilts wool to the same standard as the fourth of the Merino-Ryeland.” (Communications to the Board of Agriculture, vol. v. p. 438.) Several other distinguished individuals have taken a lead in improving the fleeces of our native short-woolled breeds, by crossing them with the Merinos, and, while their patriotic exertions deserve well of their country, have considerably increased their own profits. At the head of these, perhaps, we ought to place Lord Somer¬ ville, who undertook a voyage to Portugal for the sole purpose of selecting from the best Spanish flocks such sheep as united in the greatest degree the merit of a good carcass to a superior fleece. Notwithstanding the difficul¬ ties he had to encounter, augmented by the war between Great Britain and Spain, he brought home, in 1801, a flock of the first quality, selected from the Trashumante or travelling breeds of Merinos, which was the admiration of the Spanish shepherds through whose flocks they pass¬ ed in their journey to England. Small flocks of Merinos are now established in Ireland and Scotland; and the An late Mr Malcolm Laing was very successful with a numer- t' ' ous one, so far north as the Orkney Isles. ^ We shall conclude our account of this valuable race andMei its cross-breeds with an extract from a letter sent by Mr and Birkbeck, a professional farmer of the highest class, to Drbov Parry, and quoted by the doctor in the essay above re¬ ferred to. “ The fleeces of the first cross (between Me¬ rinos and South Downs), washed, are to the parent South Downs as six to five in weight, and as three to two in value per pound. Thus, 100 South Down fleeces, 2-| lb. each at 2s. L.25. 100 First cross 3 lb 3s. LAS. « So much for wool; and were it not for the air of ex¬ travagance it might give my statement, I should add, that there is an evident improvement, as to usefulness of form and disposition to fatten, in a large proportion of in¬ dividuals. I had the courage to exhibit at Lord Somer¬ ville’s show, in March last, five ewe-hogs from your rams, and the honour to bear away the prize from all competi¬ tors, by the merit of carcass and fleece jointly. On the whole, I believe that the improvement of the w ool may go on, without detriment to the carcass, until we shall attain a breed of sheep with Spanish fleeces and English consti¬ tutions ; but I am also convinced that this must be the re¬ sult of careful and judicious selection.” 3. Fatting. landAg After what has been said in the chapter on arable (see Turnips, page 286), and in the second chapter (seetin Pastures, page 310), little remains to be added on this point. The age at which sheep are fatted depends upon the breed, some breeds, such as the Leicester, maturing at an earlier age than others under the same circum¬ stances ; and also on the abundance and quality of the food on which they are reared, a disposition to early obe¬ sity, as well as a gradual tendency towards that form which indicates a propensity to fatten, being materially promoted by rich food, while the young animals are yet in a growing state. On good land, the Leicester wethers are very generally brought to a profitable state of fatness before they are eighteen months old, and are seldom kept on for fatting beyond the age of two years. The High¬ land breeds, on the other hand, though prepared, by means of turnips, a year at least sooner than they could be in former times, usually go to the shambles when from three to four years old. The ewes of the first description are commonly fatted after having brought lambs for three seasons, that is, after they have completed their fourth year ; and those of the small breeds at from five to seven years of age, according to circumstances. Besides the numerous flocks fatted on pastures for they supply of the market during summer, a very large propor¬ tion, especially of the sheep kept on arable land, is fatted chiefly on turnips, the winter and spring consumption o butcher-meat being now abundantly provided for by means of this root, in all those districts where the best courses of husbandry prevail. We have already mentioned the weight of the different breeds in the description of them —the mode of feeding, under the heads of Pastures an Turnips—and shall now only add, that it is an invanab e ( rule with all good managers, never to allow this, or anyr other animal reared solely for the shambles, ever to lose flesh, from its earliest age till it is sent to the butcher,— that it is found of much advantage, with a view to spec ) fattening, as well as to the economy of food, to separa e a flock into divisions corresponding with its different ages and the purpose of the owner as to the time of carryinr them to market;—and that the change from the foo 0 AGRICULTURE. 337 1 store to fattening stock—from that which is barely ca- * pable of supporting the condition which they have already attained, to that which is adapted to their speedy im¬ provement in fatting—ought to be gradual and progres¬ sive. Thus, very lean sheep are never, in good manage¬ ment, put to full turnips in winter, nor to rich pastures in summer; they are prepared for turnips on good grass¬ ed often on the aftergrass of mown grounds ; and kept on second year’s leys, and afterwards a moderate allow¬ ance of turnips, if they are to be fatted on pastures. It is a common practice, in the instance of the Leicesters, to keep all that are not meant for breeding always in a state of fatness ; and, after full feeding on turnips through winter and spring, to finish them on the first year’s clovers early in summer, when the prices of meat are usually the Hour' lamb: highest. The luxury of the age has called forth the ingenuity of man to accelerate the course of nature, at an expense which, in this species in particular, is in no degree com¬ pensated by the intrinsic value of the young animal as human food. House-lambs are fed in such numbers as the demand may require, in the vicinity of London and other large towns, where they are sold in the early part of the season, commonly at much higher prices than fat sheep of full growth. The Dorsetshire breed, as we formerly ob¬ served, can be made to yean at almost any season of the year, and they are therefore the only kind kept near Lon¬ don. But in the neighbourhood of those towns where the rich are willing to dispense with lamb during the early part of winter, other breeds are made to furnish the sup¬ ply at a more advanced period of the season. The following account of the London practice may be useful to those farmers who find it their interest to give their attention to this branch of management:— “ The sucklers, salesmen, and butchers of London are aware that such lambs as have sharp barbs on the inside of their lips are certainly of a deep colour after being butchered; and all those whose barbs are naturally blunt do as certainly produce fair meat. “ This knowledge has been the occasion of many lambs of the latter kind being kept for rams, and sent into Dorset¬ shire, expressly for the purpose of improving the colour of the flesh of house-lambs. “ The issue of such rams can generally be warranted fair, and such meat always sells at a higher price ; hence arose the mistaken notion, that Middlesex rams were ne¬ cessary to procure house-lambs. “ The sheep, which begin to lamb about Michaelmas, are kept in the close during the day, and in the house dur¬ ing the night, until they have produced twenty or thirty lambs. These lambs are then put into a lamb-house, which is kept constantly well littered with clean wheat-straw; and chalk, both in lump and in powder, is provided for them to lick, in order to prevent looseness, and thereby preserve the lambs in health. As a prevention against gnawing the boards, or eating each other’s wool, a litttle wheat-straw is placed, with the ears downwards, in a rack within their reach, with which they amuse themselves, and of which they eat a small quantity. In this house they are kept with great care and attention until fit for the butcher. “ ihe mothers of the lambs are turned, every night at etght o’clock, into the lamb-house to their offspring. At ®lx 0 ^ofk in the morning these mothers are separated rom their lambs and turned into the pastures; and, at eight o clock, such ewes as have lost their own lambs, and t lose ewes whose lambs are sold, are brought in and held n the head till the lambs by turns suck them clean : they are then turned into the pasture; and at twelve o’clock, , VOL. II. the mothers of the lambs are driven from the pasture into Agricul- the lamb-house for an hour, in the course of which time ture. each lamb is suckled by its mother. At four o’clock all the ewes that have not lambs of their own are again brought to the lamb-house, and held for the lambs to suck ; and at eight the mothers of the lambs are brought to them for the night. “ This method of suckling is continued all the year. The breeders select such of the lambs as become fat enough, and of proper age (about eight weeks old), for slaughter, and send them to market during December and three or four succeeding months, at prices which vary from one guinea to four, and the rest of the year at about two guineas each. This is severe work for the ewes, and some of them die under excess of exhaustion. However, care is taken that they have plenty of food; for when green food (viz. turnips, cole, rye, tares, clover, &c.) begins to fail, brewers’ grains are given them in troughs, and second-crop hay in racks, as well to support the ewes as to supply the lambs with plenty of milk; for if that should not be abundant, the lambs would be¬ come stunted, in which case no food could fatten them. “ A lamb-house, to suckle from one hundred and sixty to one hundred and eighty lambs at a time, should be se¬ venty feet long and eighteen feet broad, with three coops of different sizes at each end, so constructed as to divide the lambs according to their ages.” (Middlesex Report, p. 355.) Sect. IV. Swine. Though there are manypnstances of this species of live Swine a stock being kept in such numbers as to be a source ofsubordi- very considerable emolument to their owners, yet, gene- n.ate sPe" rally speaking, swine are viewed by farmers merely as a subordinate concern ; and perhaps, in most cases, their 1 chief value is held to consist in their being maintained on what would othemise be entirely lost. With millers, brewers, distillers, and dairymen, they are an object of more importance, and return, for the offals they consume, a greater weight of meat (according to some, double the weight) than could be obtained from cattle. In those parts where potatoes are raised as a fallow crop, much be¬ yond the demand for them as human food, as is the case in particular in Ireland and the west of Scotland, the rear¬ ing and feeding of swine, most of which are sent to a dis¬ tance in the state of bacon and pickled pork, is a branch of management on which great dependence is placed for the payment of their rents and other charges. It has been made a question, whether swine will pay for being wholly fed on crops raised for this purpose; and various calculations have been offered, to show how much they will return for a given quantity of corn and roots; but the results are so discordant, that much more accurate experiments must be made before any thing certain can be stated on this point. Perhaps the prin¬ cipal consideration which affects the question is, the extremely prolific nature of the animal, which renders it easy, in a very short time, to supply them in too great numbers for the demand. It is this circumstance, probably, that has, more than any other, prevented the farmers of arable land from employing any large portion of their crops in feeding swine, the flesh of which varies in price more than that of other butcher-meat, and often at very short intervals. Yet if their food be herb¬ age and roots, with a small allowance of corn or pulse in the last stage of fatting, and if the breeds are judicious¬ ly chosen and well managed, there seems no reason to doubt that, in many situations, swine will yield as much, 338 AGRICULTURE, Agricul- perhaps, on an average of years, a greater profit, for the ture. food they consume, than any other species of live stock. It is only in particular districts that so much attention has been paid to this animal as to give rise to any accu¬ rate distinction of breeds; and nowhere has it received any considerable portion of that care in breeding which has been so advantageously employed on the other ani¬ mals of which we have treated. Yet among none of the varieties of those is there so great a difference as among the breeds of this species, in regard to the meat they re¬ turn for the consumption of a given quantity of food. Some races can with difficulty be made fat, even at an ad¬ vanced age, though fed from the trough with abundance of such food as would fatten any other animal; while others contrive to raise a valuable carcass out of materials on which no other creature could subsist. Breeds. Mr Culley mentions only three breeds, viz. the Berk¬ shire, the Chinese, and the Highland or Irish; but other writers have found a distinct breed in most of the coun¬ ties of England, which they have thought proper to de¬ scribe separately. The Chinese race has been subdivided into seven varieties or more; and it would be easy to point out twice the number of as prominent distinctions among the sorts in the third class. But such an affectation of accuracy is as useless as it would be tedious. One gene¬ ral form, approaching to that of other animals kept for their carcass, ought certainly to be preferred; and the size, which is the other distinguishing characteristic, must be chosen with a view to the food provided for their main¬ tenance, and not because it is possible to raise the indi¬ viduals to a great and probably unprofitable weight. The fineness of bone, and the broad though also deep form of the chest, denote in this, as in the other species, a dispo¬ sition to make fat with a moderate consumption of food ; and, while it may be advisable to prefer the larger breeds in those places where bacon and flitches are in most de¬ mand, the smaller breeds are most esteemed for pickling, and are, beyond all doubt, most profitable to those far¬ mers who allow them little else than the range of the farm-yard and the offals of the kitchen. The Berkshire pigs, now spread through almost every part of England and several places of Scotland, are in general of a reddish colour, with black spots, large ears hanging over their eyes, short-legged, small-boned, and inclined to make fat. The surprising weight that some of these hogs have been fed to would be altogether in¬ credible, were not the facts w^ell attested. “ On Monday the 24th of January 1774, a pig (fed by Mr Joseph Law- ton of Cheshire) was killed, which measured, from the nose to the end of the tail, three yards eight inches, and in height four feet five inches and a half. When alive*' it weighed 12 cwt. 2 qrs. 10 lb.; when killed and dressed, it weighed 10 cwt. 3 qrs. 11 lb. or 86 stones 11 lb. avoir¬ dupois.” (Culley on Live Stock, p. 173.) The Hampshire breed of hogs is also very large, being longer in the body and neck, but not of so compact a form, as the Berkshire: they are mostly white, and well dis¬ posed to fatten. The Sussex pig is distinguished by being black and white, but not spotted, frequently black at both ends, and white in the middle. Their general size, when full-grown, is about 18 or 20 stone. The Suffolk white pig stands high, is narrow on the back, with a broad forehead ; the hair is short, with many bristles; weight 16 to 19 stone. The Cheshire breed is distinguished by their gigantic size: in colour they are black and white, blue and white (not spotted, but in large patches of black or blue), and some all white. Their heads are large, with very long ears, remarkably long in the body, very narrow in proportion to A, their size, with large bones, long legs, and much loose skin. : l The Shropshire pig is also a large, coarse animal, with ^ \ much bone and hair, and many bristles; their colour mostly white, with black patches, some rather sandy. They are said to be much liked by the distillers. The largest breed of the island is supposed to be kept about Rudgewick, on the borders of Sussex and Surrey. They feed to an extraordinary size, and weigh, at two years old, nearly double or triple the weight of most other sorts at that age. {Middlesex Report.) The Chinese breed is of different colours, white, black, black and white in irregular patches, and of a sandy hue; and their size is no less varied, though all of them smaller than the breeds already mentioned. The larger sort, such as weigh 10 or 12 stones when about a year old, or rather perhaps a cross with some native breed, may be recom¬ mended as the most suitable kind for arable farms, when their maintenance is to be got chiefly in the fold-yards. The form of the Chinese pig is generally good, and their flesh excellent; but it is ehsily made too fat for delicate stomachs. The most numerous in the lowland counties of Scot¬ land were, and in many places still are, very unprofitable animals. They are of a white colour; have light, narrow carcasses, with bristles standing up from nose to tail; long legs; and are very slow feeders, even at an ad¬ vanced age. In the Highlands and Hebrides the breed, supposed by Dr Walker to be the aboriginal, is of “ the smallest size, neither white nor yellow, hut of a uniform grey colour, and shaggy, with long hair and bristles. They graze on the hills like sheep; their sole food is herbage and roots, and on these they live the whole year round, without shelter, and without receiving any other suste¬ nance. In autumn, when they are in the best order, their meat is excellent, and without any artificial feeding; but when driven to the low country, they fatten readily, and rise to a considerable bulk.” (Walker’s Hebrides, vol. ii. p. 17.) In the Orkney Islands they are commonly of a dark red, or nearly black colour, and have long bristles, with a sort of coarse wool beneath them. The mode of breeding, the food, and the general ma-M; nagement of swine, are all of them so much dependent onnie local circumstances, and are so much varied in conse¬ quence, that it is neither possible, nor would it be of any utility, to describe the practice of different counties, or rather of almost every different individual. The period of gestation with swine is 16 weeks. The pigs are commonly weaned when six weeks old; soon after which the sow is again in season, so that two litters are usually farrowed within the year ; sometimes, though very rarely, five litters in two years. There are two things of particular importance to be attended to in the breeding of swine. They should not be allowed to farrow in winter, as young pigs are exceedingly tender, and can with difficulty be preserved in very cold weather; nor at a time when food is scarce, as is generally the case upon corn-farms in summer, if the stock of them is large. The months of February and August have been recommended as the best periods for parturition. (Henderson on Swine, p. 27.) Twenty swine are estimated to bring at an ave¬ rage seven pigs and a half each for their first litter (Ibid. p. 17); but the number varies much, and many young pigs are lost soon after their birth by the unkindness of their dam, and by casualties, to which they are more ex¬ posed than most other young animals. A sow in pigs should be separated from the herd some time before she is expected to farrow, carefully watched, and littered with a small quantity of dry short straw. Too much straw is improper, both at the time of farrowing AGRICULTURE. 339 ul and for a week or two afterwards, as the pigs are apt to An ■. * nestle beneath it unperceived by the sow, and are thus ^/- ^in danger of being smothered when she lies down. A breeding sow should be well fed, particularly when nurs¬ ing ; and it is advantageous early to accustom the pigs to feed from a low trough, on milk or other liquid food mixed with meal or bran. Such of the pigs of both sexes as are not to be kept for breeding are usually castrated or spayed when about a month old, and the whole may be weaned at the end of six or seven weeks. They should then be fed regularly three times a day, with meal and water a little warmed, until they are able to shift for themselves among the rest of the stock. The food allowed, whether to growing or fattening swine, depends on the circumstances of their owners. The cottager’s pig must be contented with the scanty offals of his kitchen and of his dairy, the produce gene¬ rally of a single cow. Towards the end of autumn a few potatoes are added, for the purpose of preparing it for slaughter, and perhaps a little meal is mixed with boiled potatoes for a week or two before. Such pigs, however, often thrive amazingly, make themselves moderately fat, and form a most valuable addition to the winter stores of their owners. In the south-eastern counties of Scotland, the hinds or married ploughmen are commonly allowed to keep a pig each, which they feed in this manner, and from which their families derive much benefit at very little ex¬ pense. On many corn-farms, the chief, and not unfre- quently the only dependence of swine, is on the straw- yards. The sweepings of the barn-floor, corn left upon the straw, and oats found among the dung of horses, with a share of the turnips given to the cattle in winter, and of the clover in summer, afford ample subsistence to swine, in the proportion, perhaps, of one to every five or six acres under corn, clover, and turnips. The kitchen and dairy give some assistance to pigs newly weaned, and also to such as are soon to be slaughtered. A great many are killed when about a year old that have never been fed at any expense that can be estimated. A fbw pigs, if of a good breed, will always be moderately fat at that age with the run of the straw-yards, and their flesh is of an excellent quality. lee ig When farmers find it profitable to keep large swine that 1 r un- cannot be fattened for bacon, as is the practice in some of the western counties, without a regular supply of food being served up to them, the method is, to rear them chiefly on raw potatoes and Swedish turnips, and to fatten them on these roots boiled or prepared by steam, with a mixture of oat, barley, or bean and peas meal. Their troughs should be often replenished with a small quantity of food at a time, and kept always clean ; and their food changed occasionally, and seasoned with salt. “ If proper care be taken,” says a late writer, “ a feeding pig should not consume more than six Winchester bushels of oats made into meal. It ought to be shelled before it is ground, the same as for family use, but need not be sifted.” (Henderson’s Treatise on Swine, p. 26.) Swine, it is well known, are very apt to get into for¬ bidden ground: upon tillage farms they are seldom, for this reason, permitted to go at large, unless sometimes for a few weeks on the stubbles, or where the number is so large as to afford the expense of constant herding. In many cases they are almost always confined to the cattle- Moi of yard, or a fold-yard beside their styes. Another bad pro- J’^j j‘ngPerty in this animal is, the habit of digging into the gin] S0'^ ’ ^or which the most effectual preventive is, to cut the two strong tendons of their snout, by a slight incision ^ ith a sharp knife, about an inch and a half from the nose, this may be done with little pain, and no prejudice to the animal, when about two or three months old. The Agricul- common practice of restraining them by rings fixed in the ture. snout is painful and troublesome: they must be replaced as often as they give way; and that happens so frequently, that rings afford but little security against this nuisance. Styes or swine-houses are set down in different situa-Styes, tions, according to the numbers kept, and the manner of feeding them. The cottager erects a little hut contigu¬ ous to his dwelling, and many small farmers also choose to lodge them near the kitchen. If swine are kept chiefly in the straw-yard, their houses are so situated as to give ready access by a door which opens into it. See Plate XI. The gentleman-farmer erects a range of low buildings on that side of his farm-offices which is least exposed to view, and incloses and subdivides a small yard for their use. Where this branch of husbandry is carried on in all its parts, there must be separate houses for sows heavy with young, for such as are nursing, for pigs newly weaned, and for rearing and for fattening stock. (General Re¬ port of Scotland, vol. iii. p. 217.) In the pickling and kitting of pork, a branch of business which is carried on to a considerable extent at many of our seaports, the carcass is cut in pieces, and packed in kits made for the purpose, containing from one to two cwt. Salt is dissolved in water till the mixturb be strong enough to swim an egg; it is then boiled, and, when cold, poured upon the pork. When the end of the kit is fixed in, the article is ready for being sent to market. A late writer has given particular directions for the curing of bacon, founded upon a long course of experience, which therefore deserve to be more generally known. We shall give them in his own words. “ After the carcass has hung all night, lay it upon a Directions strong table or bench, upon its back, cut off the head f°r curing close by the ears, and cut the hinder feet so far below the^acon’ hough as will not disfigure the hams, and have plenty of room to hang them by. Then take a cleaving knife, and, if necessary, a hand-mallet, and divide the carcass up the middle of the back-bone, laying it in two equal halves. Then cut the ham from the side by the second joint of the back-bone, which will appear on dividing the carcass ; then dress the ham, by paring a little off the flank or skinny part, so as to shape it with a half-round point, clear¬ ing off any top fat that may appear. The curer will next take off the sharp edge along the back-bone with his knife and mallet, and slice off the first rib next the shoulder, where he will perceive a bloody vein, which he must take out, for if it is left in, that part is apt to spoil. The cor¬ ners must be squared off where the ham was cut out. “ In killing a number of swine, what sides you may have dressed the first day lay upon some flags or boards, piling them across each other, and giving each flitch a powder¬ ing of saltpetre, and then covering it with salt. Proceed in the same manner with the hams by themselves, and do not omit giving them a little saltpetre, as it opens the pores of the flesh to receive the salt, and besides gives the ham a pleasant flavour, and makes it more juicy. “ Let them lie in this state about a week, then turn those on the top undermost, giving them a fresh salting. After lying two or three weeks longer, they may be hung up to dry in some chimney or smoke-house. Or, if the curer chooses, he may turn them over again, without giving them any more salt; in which state they may lie for a month or two without catching any harm, until he has convenience for drying them. I practised for many years the custom of carting my flitches and hams through the country to farm-houses, and used to hang them in their chimneys and other parts of the house to dry, some sea¬ sons to the amount of five hundred carcasses. This plan I 340 AGRICULTURE. Agricul- soon found was attended w5th a number of inconveniences, ture. yet it is still common in Dumfries-shire. “ About twenty years ago I contrived a small smoke¬ house. " h°use> of a very simple construction. It is about twelve feet square, and the walls about seven feet high. One of these huts requires six joists across, one close to each wall, the other four laid asunder at proper distances. To re¬ ceive five rows of flitches, they must be laid on the top of the wall. A piece of wood, strong enough to bear the weight of one flitch of bacon, must be fixed across the belly end of the flitch by two strings, as the neck end must hang downwards. The piece of wood must be longer than the flitch is wide, so that each end may rest upon a beam. They may be put so near to each other as not to touch. The width of it will hold 24 flitches in a row, and there will be five rows, which will contain 120 flitches. As many hams may be hung at the same time above the flitches, contrived in the best manner one can. The lower end of the flitches will be within 2^ or 3 feet of the floor, which must be covered five or six inches thick with saw¬ dust, which must be kindled at two different sides. It will burn, but not cause any flame to injure the bacon. The door must be kept close, and the hut must have a small hole in the roof, so that part of the smoke may ascend. That lot of bacon and hams will be ready to pack up in a hogshead to send off in eight or ten days, or a little longer, if required, with very little loss of weight. After the bacon is salted, it may lie in the salt-house as described, until an order is received, then immediately hang it up to dry. “ I found the smoke-house to be a great saving, not only in the expense and trouble of employing men to cart and hang it through the country, but it did not lose nearly so much weight by this process. “ It may be remarked, that whatever is shipped for the London market, or any other, both bacon and hams, must be knocked hard, and packed into a sugar hogshead, or something similar, to hold about ten hundredweights. Bacon can only be cured from the middle of September until the middle of April.” (Henderson’s Treatise on Swine, p. 39.) Brawn. The treatment of boars for brawn, and the after-pre¬ paration of the article, is carried on in Kent and some other parts of England ; but it is the object of those concerned in this business to keep the process secret. According to answers returned to queries transmitted by the Board of Agriculture in 1804, the boars are put up for feeding at all ages, and in an entire state; but they are preferred when only two years old. They were usually kept apart, each of them in a case so small as not to be able to turn round, but sometimes eight together in larger pens. Their food is beans, with sulphur given in their water. A large ani¬ mal is preferred, producing a collar of about 30 lb. weight, which then brought 2s. per lb.; the lean parts being made into sausage meat, and sold at 6d. per lb. {Farmer s Ma¬ gazine, vol. vi. p. 431.) Sect. V. Miscellaneous Live Stock. Under this title we would comprise Asses, Mules, Goats, Rabbits, Pigeons, Poultry, and Bees. The value of these animals, as agricultural live stock, is comparatively inconsiderable in Britain, notwithstanding their importance in some other countries; and, in an eco¬ nomical view, some of them are undoubtedly wasteful and Asses and pernicious. Asses and mules are seldom or never employ- n.ules. ed in field labour, though it was the opinion of Mr Bake- well, and a few other eminent agriculturists, that there would be some advantage in propagating the ass on ac¬ count of its hardiness, and the coarse food on which it may be maintained. Trials have been made to improve our t\ present breeds, by crosses with males introduced from foreign parts, without having had the effect, however, oT' bringing them into use, either for the plough or the cart- and wherever the services of a small animal are required* we have horses of all sizes, from nine to eighteen hands high, which seem better adapted to every purpose than asses or mules. Goats are to be found only in small Go numbers, except in some parts of the Highlands, and are kept chiefly for the medicinal quality of their milk. Pi. Pi^ geons are justly considered as a nuisance by every respect¬ able writer on rural economy, and certainly by every far¬ mer who is within the reach of their depredations. Rabbits axe a kind of stock about which some difference Ka of opinion still exists among intelligent men, though there are perhaps very few situations in which they can be con¬ sidered as more profitable than any other mode of occu¬ pancy. It is not merely that they in general return less for their food than other stock, but that they are also very difficult to confine, and most destructive to the crops and fences in their vicinity. Their number, though still con¬ siderable, has accordingly decreased, and continues to de¬ crease, with the progress of improvement; and unless their skins shall become of much greater value than at pre¬ sent, they can be an object of consideration only on such tracts as must otherwise be left to the animals that are still in a state of nature. In the present state of our agri¬ culture, however, if it be found advantageous to retain this species, it is proper that the best breeds and the best mode of management, as well as their value, should be known. A deep, sandy, poor soil is the most suitable for rabbits, though, under good management, as turnips must be pro¬ vided for winter, there should be parts of it capable of bearing that and other crops; and the situation may be either on the sides of hills or on a flat surface. Artificial burrows are made with an auger, to reconcile them to the ground, and to preserve them from vermin, until they have time to make their own burrows; and on level warrens, this implement may be usefully employed from time to time afterwards. Warrens are commonly fenced with a sod wall, capped with furze or black thorn, in all about six feet high, and should always be kept in complete repair. Besides the rabbits, a number of sheep are usually kept in these grounds during the summer. The silver-haired rabbit is now more esteemed than the grey, though the latter is so much hardier, that if a war¬ ren be stocked with both, there will in a few years be nothing but greys. {Lincolnshire Report, p. 382.) The skin of the grey rabbit is cut, that is, the “ wool” is pared off the pelt, as a material of hats; whereas that of the silver-haired, which sells much higher, is dressed as fur, and goes, it is said, principally to the East Indies. (Mar¬ shall’s Yorkshire, vol. ii. p. 265.) One buck will serve one hundred does; the doe takes the buck the day she brings forth, and goes thirty-one days with young, which she suckles for about twenty-two days, for the first half of which they are blind. But when confined in warrens, rabbits seldom breed more than twice a year, and some of them only once : in particularly wet, cold seasons, few or none bring more than one litter. (Parkinson on Live Stock, vol. ii. p. 299.) The skins are in their best state from the middle of November till Christmas, during which period all that are not to be kept for breeding are slaughtered. Silver skins have been sold of late at from 15s. to 21s. a dozen. “ The best manner of taking rabbits is by folds, by means of nets and cords. The day before the rabbits are intended to be taken, the warrener, with his assistants, in¬ closes many acres of ground, the bank generally making AGRICULTURE. 341 ul. one end, and sometimes part of a side : the fore part of the , " f0ld is left entirely open. Rabbits form their colonies in ^some part all together, at a distance from their feeding m ound, and nearly all leave their home or burrows at the time of feeding, when the warrener fixes his nets, by two men beginning at each end, who meet in the middle. Thus, in fine dry weather they can nearly take all that is wanted at once; but it is a general practice to fold at two sepa¬ rate times from each colony. Within the fold are formed what are termed angles, in that part nearest to the bur¬ rows; as the rabbits, when they return, and find them¬ selves checked in getting home, will beat about by the nets. These angles are therefore so contrived as to afford them an opportunity of secreting themselves, and are made thus:—an irregular groove or channel is cut, about twelve or fourteen inches deep, and about twelve inches wide, the sods being set up one against another over the groove, so as to form a ridge like the roof of a house. These channels are made of equal lengths, both ends being left open, so that when the rabbits meet they are head to head. When the rabbits find themselves prevented from returning to their former homes, and the day-light appears, hearing the warrener and his dogs enter the fold, they quickly run into the angles, when the warrener puts a sod against the open ends, to prevent their return. The few straggling rabbits remaining in the fold are hunted by boys with dogs; but the warreners have recourse to that method as little as possible, the dogs being apt to tear the skin, and injure the carcass.” (Parkinson on Live Stock, vol. ii. p. 299.) “ Turnips, clover, and sainfoin are the most proper kinds of winter food for rabbits, as also threshed oats or barley, when corn is tolerably cheap, may be given them with great propriety. The two latter need only be allowed when die ground is covered with snow, and when it does not blow about so as to cover the corn when laid down; but in severe storms, turnips are the most proper food, as they can find them by their scent, and will scratch the snow off when covered. Three large cart-loads of turnips a day' will fodder one thousand or one thousand one hundred couples of rabbits, which are about a proper quantity to be left as breeding stock on 500 acres of inclosed warren land. In heavy snows, a great deal of money must be ex¬ pended in clearing the snow from the warren walls, in order to keep as much as possible the rabbits within their bounds.” {Lincolnshire Report, p. 389.) )e Among several calculations to show the expense and '* produce, Mr Arthur Young seems to consider the follow¬ ing as the most accurate; and as he is a decided enemy to this stock, there is no reason to suspect exaggeration. “ Mr Holdgate states the expense of 1700 acres under rabbits, the silver sort, thus :— Labour, three regular warreners, with extra-assistance at killing L.85 0 0 Fences 42 10 0 Winter food 42 10 0 Nets, traps, &c. &c 14 3 4 Delivery 21 5 0 Lent is said to be 7s. an acre 595 0 0 L.800 8 4 The capital employed is that sum, with the addition of stock paid for; suppose this three couples an acre, at 2s. 4d 595 0 0 L.1395 8 4 oterest of that sum one year, 5 per cent 69 5 0 L.1464 13 4 Annual Account.

Of Poultry, the most difficult to rear, and the most vo- Poultry, racious and unprofitable, is the turkey. Geese, which live, and even fatten on grass, are considered by some persons as the most valuable, and in many parts of England the number is considerable. Ducks are not only compara¬ tively harmless, but, from their feeding chiefly on perni¬ cious insects, are probably deserving of more attention than has hitherto been paid to them. But common fowls are by far the most numerous, and everywhere add some¬ thing not inconsiderable to the income of the inhabitants of the country, and to the stock of food for the consump¬ tion of the people at large. The trade in eggs alone, be- Eggs, tween the country and the towns, is a matter of some im¬ portance, as affording profitable employment to those wrho collect them, and to others who afterwards send them in large quantities to the principal towns. According to the statistical account of Scotland, the people of Hawick, a small town in the county of Roxburgh, more than twenty years ago received L.50 weekly through the year, for eggs collected in the neighbourhood, and sent to Berwick for the London market; and in 1796 it was calculated that the peasantry of Mid-Lothian drew L.8000 a year for poultry and eggs. But in the way these fowls are com¬ monly managed by farmers, there is reason to doubt whether they pay for the food they consume, and the waste they are too often allowed to commit. The num¬ ber kept by any individual is commonly so small as to obtain little of that attention that is given to other do- * mesticated animals, and their ravages are accordingly greater, and the returns smaller, than they would other¬ wise be.* Yet in the warm cottages of country labourers, the common farm-yard hen makes a valuable return for the food she requires, which is frequently potatoes, boiled and mashed, with a little oat-meal porridge, a portion of the daily meal of its owner. A comfortable degree of warmth is so essential, that some gentlemen have had stoves placed under their roosts. ^ The results of an experiment made with six hens and f^fpro? a cock in 1807 and 1808 were, that they ate half a peck duceI of ’ of barley weekly, with very little other food, and laid 764COmmon eggs in 52 weeks, the greatest number in the months offowls. 342 AGRICULTURE.

(Parkinson on Live Stock, vol. ii.) CHAP. IV. GENERAL OBSERVATIONS ON THE AGRICUL¬ TURE OF BRITAIN. Superio- The husbandry of a great part of Britain, both in re- rity of spect to the cultivation of the soil and the breeding and British management of live stock, is confessedly superior to that lure: * any °^ler country in Europe; and the quantity and value of its products, considering the character of the cli¬ mate, as well as the industry, wealth, and respectability of its husbandmen, are without any parallel either in ancient or modern times. We find from Columella, that, under • the Romans, the produce of the greater part of Italy was less than four times the seed (lib. iii. cap. 3); and this notwithstanding an unproductive fallow every second year, and apparently a much greater attention to minutiae than would be compatible with the more extensive con¬ cerns of the British farmer. The average crops of Bri¬ tain have been stated so high as nine times the seed, and certainly, wherever the management is tolerably cor¬ rect, cannot be less than double the proportion assigned by Columella to the richer soil and more genial climate of Italy. Of the agriculture of France before the Revo¬ lution a very full and accurate account has been furnished by Mr Arthur Young, from which it is sufficiently evi¬ dent how much the general produce of that country, the best cultivated perhaps next to Britain, was inferior to that of even our middling lands; and the progress it has made since has not, according to the latest and apparent¬ ly exaggerated accounts, been marked by any very great improvement either in live stock or machinery, the two most distinguishing parts of British husbandry. It is natural to ask, to what causes this superiority is owing; and why it is confined to a part of our territory, instead of being extended, as our great demand of late for foreign corn would have led us to expect, to all soils that are capable of profitable improvement. On these two points we now propose to offer a few very general re¬ marks ; and we shall submit them to the reader without affecting that precision of arrangement which more ample details would have required. Division 1. The territory of Britain is not engrossed by a few oflandad individuals, like the northern countries of Europe, nor property, divided into such minute portions as that of some of the small states of the Continent. The vast tracts of country held by a Russian or Polish nobleman, and the diminutive possessions of the Swiss, and more lately of the French peasantry, are almost equally inconsistent with the more Objections productive systems of rural economy. The former are too large for the superintendence of one individual with a view to profitable cultivation; and the existence of such extensive properties implies the degradation and poverty of the great body of the people, and the absence of a middle class, possessed of disposable capital, or at least of opportunities for its investment in the soil. The latter, on the other hand, afford no room for the employment of to very large estates; capital, nor of those inventions by which the charges of & cultivation are diminished, and its products augmented. Such small landed properties return little more than the''-' wages of the manual labour by which they must necessa-an rily be cultivated. Their small surplus produce, which™’ every bad season annihilates, cannot afford subsistence to [Is those other classes whose labours are necessary to na-pn tional prosperity and individual comfort; and a part of the families of the cultivators themselves, having neither food nor employment at home, must either emigrate or perish. To a certain extent these consequences have been already experienced, both in Ireland and the High¬ lands of Scotland; for it would be idle to maintain that a minute division of land in tenancy does not produce all the unhappy effects which must result from the minute division of land in absolute property. Of two counties, in one of which estates are in general Ef too large for the personal superintendence of the pro-to' prietors, and, in the other, the land is parcelled out into801 shares little more than sufficient for the subsistence of8!” their owners, the condition of the great body of theSai people must be very much alike. In neither can there exist that middle class from which all valuable improve¬ ments proceed, nor any of those inventions which multi¬ ply and augment the productive powers of human indus¬ try. Both of these states of property must appear de¬ cidedly unfavourable to national prosperity, when measured by this unerring test—the quantity of the products of the soil which remains after defraying the charges of obtain¬ ing them; for upon this net surplus depend all the en¬ joyments of mankind beyond the mere necessaries of life, as well as the means of repelling foreign aggression, and preserving internal tranquillity. The distribution of the landed property of Britain is equally distant from both these extremes. Though it is necessary, perhaps, to the political constitution of the country, that there should be a number of large estates, yet their extent is seldom so great as to produce any of the bad effects just mentioned, even within the bounds of a single county. Over the rural economy of the nation these large properties exert scarcely any influence at all, excepting such of them as are held by entail, which is cer¬ tainly a mode of tenure greatly at variance with the full improvement of the soil. Many instances might be point¬ ed out, of very extensive estates, fully as well cultivated, and yielding as large a surplus for the general consump¬ tion, as our agriculture, in its present state, obtains from any equal extent of similar land. It is true, that to in¬ crease the political influence of great proprietors, too many of these estates are possessed by tenants at will; but this grievance is not peculiar to such estates, the largest estates of Scotland being occupied on leases. This most serious obstacle to spirited cultivation must therefore be ascribed to political causes, and not to the engrossing of landed property. 2. Another arrangement, which may serve to account Bi for the superiority of British agriculture, is somewhat™ akin to that division of labour by which all the arts have ^ been carried to so great a degree of perfection in this country. Few great proprietors, comparatively, cultivate their own lands beyond the demands of pleasure and convenience. The far greater part of Britain is culti¬ vated by professional men, with their own capital, and for their own profit. The price which they must pay for their temporary rights in the soil, in the shape of rent, instead of checking their exertions, has a powerful ten¬ dency to promote every profitable improvement, to dis¬ courage dangerous speculation, and to restrain wastelm expenditure. And as it is clearly the interest of such oil. re. >a of 1 rtr, sof n re. the o iteil lies- men AGRICULTURE. A ui. men, still more than of proprietors themselves, to obtain tip. the largest produce at the least possible expense, the in- ^termediate portion of the produce—that which is dis¬ posable for the general consumption—is consequently as large as industry and economy, in the present state of our agriculture, can make it. It is true almost to a pro¬ verb, that farming upon an extensive scale is never profit¬ able to a great landholder; and, with a view to the inte¬ rest of the nation, it ought to be discouraged, as both wasteful and unproductive. In some countries this mode of farming is a matter of necessity, as in the north of Europe, where a class of free tenants does not exist; in others the business of cultivation must be carried on as a sort of partnership, or joint concern between the pro¬ prietor and tenant, as on the mctairies of France. For¬ tunately, the general distribution of wealth has long since removed the necessity for either of these methods in Bri- i! tain. To give full effect to the professional system, it is ne¬ cessary that the rights of the landlord and tenant, re¬ spectively, should be clearly defined and well secured by law and the private contract of the parties. The general principle which should regulate the terms of this connec¬ tion seems to be, that while the farm ought to be restored to the owner at the expiration of the tenant’s interest, at least without deterioration, the tenant should be encou¬ raged to render it as productive as possible during his possession. In both of these views a lease for a term of years is scarcely less necessary for the interest of the landlord than of the tenant; and so much is the public interested in this measure, that it has been proposed by intelligent men to impose a penal tax on the rent of lands held by tenants at will. I hat the value of the property is enhanced by the se¬ curity which such a lease confers on the tenant, will be put beyond all doubt, if the rents of two estates for half a century back are compared; the one occupied by ten¬ ants at will, and the other by tenants on leases for a mo¬ del ate term, and where the soil and situation are near¬ ly alike in every respect. If the comparison be made 343 Agricul¬ ture. L'onn ■ tion 6- ;weei> andl I indti;int. Wva true that, under the security of the honour of an English andlord, tenants at will have been continued in posses¬ sion from generation to generation, and acquired wealth which he has never, like the landholders of some other countries, attempted to wrest from them. But there are few individuals in any rank of life who continue for a length of time to sacrifice their just claims on the altar of pure generosity. Something is almost always expected in return. A portion of revenue in this case is exchanged for power, and that power is displayed not only in the habitual degradation of the tenantry, but in the control over them, which the landlord never fails to exert at the election of members of Parliament, and on all other poli¬ tical emergencies. No prudent man will ever invest his fortune in the improvement of another person’s property, unless, from the length of his lease, he has a reasonable prospect of being reimbursed with profit; and the servi¬ lity which holding at will necessarily exacts is altogether incompatible with that spirit of enterprise which belongs to an enlightened and independent mind. The people at large are evidently most deeply affected by every measure which has a tendency to fetter the pro¬ ductive powers of the soil, and, at the same time, to de¬ press one of their largest and most valuable classes. It is clearly' their interest that corn and other provisions should be supplied in abundance; and the people of England may justly complain of the want of leases as one of the principal causes which check the improvement of their own territory'. What ought to be the term of a lease, can only be de-Duration termined by a reference to the circumstances of each par-of leases, ticular case. Lands naturally rich, or such as have al¬ ready been brought to a high degree of fertility, requiring no great investment of capital, and returning all or nearly all the necessary outlay within the year, may be advan¬ tageously held upon short leases—such perhaps as give time for two or at most three of the rotations or courses of crops to which the quality of the soil is best adapted. The practice of England in this respect is extremely vari- 0USj—almost every term, from twenty years downwards, ^ ^ 1. . “ ~ “iauc uuo>—annus, l eveiy term, irom twenty years aownwartls, I’1 b,ei"« found in diifere".t .of i'- I» Scotland, by far value, the advantages of leases will be still more strik¬ ing. While that which is held by tenants at will re¬ mains nearly stationary, the other is gradually yet ef¬ fectually improved, under the security of leases, by the tenant s capital; and, in no long period, the latter takes tne lead of the former, both in the amount of the reve¬ nue which it yields to the proprietor, and in the quan- ny of produce which it furnishes for the general con¬ sumption. The higher rents and greater produce of some 1 r s o Scotland, than of many of the English counties, w mre the soil, climate, and markets are much more ayourable, must be ascribed to the almost universal prac- 1Ce 0 homing on leases in the former country, in a much grea er egree than to any of the causes which have been requcntly assigned. Less than a century ago, what are fa i j ^ cultivated districts of Scotland were very ar behmd the greater part of England, and indeed had ve,7 little progress from the time of the feudal worp1^' 118 n°- ^ year.s since tlle farmers of Scotland np.- . !n le Practice of going to learn from their southern in tl 0UrS an art was then very imperfectly known thereT T C°Untry- But in several parts of England gnnt, las been .Httle or no improvement since, while the and a^rn C0Unt‘es °f Scotland have uniformly advanced, to f,:,PreSC;nt exhibit> very generally, a happy contrast condition at the middle of last century, sarv (r0S!)e.ct t0 tarRiers themselves, it cannot be neces- j point out the advantages of leases. It may be the most common period is nineteen years, to which it was formerly the practice, in some places, to add the life of the tenant. In that country, even when it is thought expedient to agree for a much longer term, this is still ex¬ pressed in periods of nineteen years,—a sort of mysterious cycle, which seems to be no less a favourite with the courts of law than with landholders and farmers. Yet this term is somewhat inconvenient, as it can never correspond with any number of the recognised rotations of arable land. It has been maintained by several writers, that a lease for twenty years is not sufficient to reimburse a tenant for any considerable improvements; and landholders have often been urged to agree to a much longer term, which, it is al¬ leged, would be not less for their own interest than for that of the tenant. This is a question which our limits do not permit us to discuss; but after viewing it in different lights, assisted by the experience of long leases in differ¬ ent parts of Scotland, we cannot help expressing some doubts of their utility, even as regards the parties them¬ selves ; and we are decidedly of opinion, that a great¬ er produce will be brought to market, from any given extent of land held on successive leases of twenty years, for half a century, than if held on one lease of that duration, whether the term be specified or indefinite, as in the case of a lease for life. As a general mode of te¬ nure, leases for lives seem to us particularly objectionable. The great advantages of a lease are so well known in Scotland, that one of her best agricultural writers, himself 3-14 AGRICULTURE. Agricul¬ ture. a landed proprietor, has suggested a method of conferring on it the character of perpetuity, to such an extent as, he thinks, would give ample security to the tenant for every profitable improvement, without preventing the landlord from resuming possession upon equitable terms, at the ex¬ piration of every specified period. But the author of this plan (Lord Karnes), in his ardent wishes for the advance¬ ment of agriculture, at that time in a very backward state in his native country, seems to have overlooked the diffi¬ culties that stood in the way of its adoption; and the great advance in the price of produce, and consequently in the rate of rents, since his Lordship wrote, has long since put an end to the discussion which his proposal ex¬ cited. For a form of a lease on his plan, the reader may consult Bell’s Treatise on Leases; and the objections to the plan itself are shortly stated in the supplement to the sixth edition of Karnes’s Gentleman Farmer, published in 1815. Long leases have been sometimes granted upon con¬ dition of receiving an advance of rent at the end of a rents. tinj -rent certain number of years ; but covenants of this kind, meant to apply to the circumstances of a distant period, cannot possibly be framed in such a manner as to do equal justice to both parties; and it ought not to be concealed, that, in every case of a very long lease, the chances are rather more unfavourable to the landholder than to the farmer. If the price of produce rise as it' has done for the last fifty years, no improvements which a tenant can be expected to execute will compensate the landlord’s loss; and if, on the other hand, prices shall decline, the capital of most tenants must be exhausted in a few years, and the lands will necessarily revert to the proprietor, as has often been the case of late. Hence a landholder, in agreeing to a long lease, can hardly ever assure himself that the obliga¬ tions on the part of the tenant will be fully discharged throughout its whole term, while the obligations he incurs himself may always be easily enforced. He runs the risk of great loss from a depreciation of money, but can look forward to very little benefit from a depreciation of pro¬ duce, except for a few years at most. Of this advantage a generous man would seldom avail himself; and, indeed, in most instances, the advantage must be only imaginary, for it would be overbalanced by the deterioration of his property. Objections Where the circumstances of a landholder, the state of to corn- his property, and the wealth and enterprising character of the tenantry, are such as to render long leases, or leases for an indefinite period, expedient, the most equitable mode, in regard to rent, would be to make it rise and fall with the price of corn or other produce. A rent paid in corn is, indeed, liable to serious objections, and can sel¬ dom be advisable in a commercial country. It necessarily bears hardest on a tenant when he is least able to dis¬ charge it. In very bad seasons his crop may be so scanty as scarcely to return seed and the expenses of cultivation; and the share which he ought to receive himself, as the profits of his'capital, as well as the quantity allotted to the landlord, may not exist at all. Though, in this case, if he pays a money rent, his loss may be considerable, it may be twice or thrqe times greater if the rent is to be paid in Corn, or according to the high price of such seasons.. In less fatourable years, which often occur in the variable climate of Britain, a corn-rent would, in numerous in¬ stances, absorb nearly the whole free or disposable pro¬ duce, as it is by no means uncommon to find the gross produce of even good land reduced from twenty to fifty per cent, below an average, in particular seasons. And it ought to be considered, in regard to the landlord himself, that his income would thus be doubled or trebled, at a time when all other classes were suffering from scarcity A; tti and consequent dearth; while, in times of plenty and U cheapness, he might find it difficult to make his expenses^ V correspond with the great diminution of his receipts. It is of much importance to both parties that the amount of the rent should vary as little as possible from any unfore¬ seen causes, though tenants in general would be perhaps the most injured by such fluctuations. To obviate these and other objections to a corn-rent,Pla and to do equal justice at all times to both landlord andcon tenant, a plan has been suggested for converting the cornaC( into money, adopting for its price, not the price of theint year for which the rent is payable, but the average pricemu of a certain number of years. The rent, according to this plan, may be calculated every year, by omitting the first year of the series, and adding a new one ; or, it may con¬ tinue the same for a certain number of years, and then be fixed according to a new average. Let us suppose the lease to be for twenty-one years, the average agreed on being seven years, and the first year’s rent, that is, the price of so many quarters of corn, will be calculated from the average price of the crop of that year, and of the six years preceding. If it be meant to take a new average for the second and every succeeding year’s rent, all that is necessary is, to strike off the first of these seven years, adding the year for which the rent is payable, and so on during all the years of the lease. But this labour, slight as it "is, may be dispensed with, by continuing the rent without variation for the first seven years of the lease, ac¬ cording to the average price of the seven years imme¬ diately preceding its commencement, and, at the end of this period, fixing a new rent, according to the average price of the seven years just expired, to continue for the next seven years. Thus, in the course of twenty-one years, the rent would be calculated only three times; and for whatever quantity of corn the parties had agreed, the money payments would be equal to the average price of fourteen years of the lease itself, and of the seven years preceding it; and the price of the last seven years of the old lease would determine the rent during the first seven years of the new one. The landlord and tenant, it has been thought, could not suffer either from bad seasons or any change in the value of the currency, should such a lease as this be ex¬ tended to several periods of twenty-one years. The quan¬ tity of corn to be taken as rent is the only point that would require to be settled at the commencement of each of these periods; and though this would no doubt be greater or less, according to the state of the lands at the time, yet it may be expected that, in the twent3r-one years preceding, all the tenant’s judicious expenditure had been fully replaced. Instead of the twofold difficulty in fixing a rent for a long lease, arising from uncertainty as to the quantity of produce, which must depend on the state of improvement, and still more perhaps from the variations in the price of that produce, the latter objection is entirely removed by this plan ; and in all cases where land is a ■ ready brought to a high degree of fertility,1 the question about the quantity of produce may likewise be dispense with. . tore Upon this plan we shall take leave to observe, that it r ^ be applied to leases of nineteen or twenty-one years, tie inconvenience resulting from uncertainty as to the amoun ^ of rent, as well as other difficulties which must necessan \ attend it, would be as great perhaps as any a(|vantare:j0'jL which it holds out to either of the parties. If it be san o that a rent determined by a seven years’ average eon not suddenly nor materially alter, this is at once to a nu the inutility of the contrivance. The first thing w ie AGRICULTURE. , must strike every practical man is, that corn is not the Aft! * only produce of a farm, and, in most parts of Britain, per- ca ^haps not the principal source from which rent is paid; and there is no authentic record of the prices of butcher- meat, wool, cheese, butter, and other articles in every county to refer to, a-s there is of corn. This is not the place to inquire whether the price of corn regulates the price of all the other products of land, in a country whose statute-books are full of duties, bounties, drawbacks, &c. to say nothing of its internal regulations ; but it is suffi¬ ciently evident, that, if corn does possess this power, its price operates too slowly on that of other products, to serve as a just criterion for determining rent on a lease of this duration. Besides, in the progress of agriculture, new species or varieties of the cerealia themselves are esta¬ blished even in so short a period as twenty-one years, the price of which may be very different from that of the corn specified in the lease. What security for a full rent, for instance, would it give to a landlord, to make the rent payable according to the price of barley, when the tenant might find it more for his interest to cultivate some of the varieties of summer wheat ? or according to the price of a particular variety of oats, when, within a few years, we have seen all the old varieties superseded, throughout extensive districts, by the introduction of a new one, the potato-oat, which may not be more permanent than those that preceded it ? There may be no impropriety in adopting this plan for ascertaining the rent of land kept always in tillage, but it would be idle to expect any im¬ portant benefits from it during such a lease as we have mentioned. In some instances it is the practice to agree for a certain rent in money, which does not vary; and another portion is determined from time to time by the price of corn, the quantity and kinds of the corn only being previously fixed by the lease. This, we think, is a better plan than to make the whole rent vary with the price of corn. With regard to much longer leases, this plan will no doubt diminish the evils which we think are inseparable from them, but it cannot possibly reach some of the most considerable. Its utmost effect is to secure to the land¬ holder a rent, which shall in all time to come be an ade¬ quate rent, according to the state of the lands and the mode of cultivation known at the date of the lease. But it can make no provision that will apply to the enlarge¬ ment of the gross produce from the future improvement of the lands themselves, or of the disposable produce from the invention of machinery and other plans for economiz¬ ing labour. Old corn-rents, therefore, though much higher at present than old money-rents, are seldom or never so high as the rents that could now be paid on a lease of twenty-one years. But, independently of these consider¬ ations, which more immediately bear upon the interests of the parties themselves, one insuperable objection to all such leases is, that they partake too much of the nature of entails, and depart too far from that commercial cha¬ racter which is most favourable to the investment of ca¬ pital, and consequently to the greatest increase of land produce. .nts A lease for a term of years is not, however, in all cases a sufficient encouragement to spirited cultivation: its covenants in respect to the management of the lands may t>e injudicious; the tenant may be so strictly confined to a particular mode of culture, or a particular course of crops, as not to be able to avail himself of the beneficial dis¬ coveries which a progressive state of agriculture never ai s to introduce. Or, on the other hand, though this is oiuch more rare, the tenant may be left so entirely at 1 erty, that either the necessity of his circumstances dur- VOL. II. 345 mg the currency of the lease, or his interest towards its Agricul- expiration, may lead him to exhaust the soil, instead of ture* rendering it more productive. When a lease therefore is' either redundant or deficient in this respect—when it either permits the lands to be deteriorated or prevents their improvement—the connection between landlord and tenant is formed upon other views, and regulated by some other principle, than the general one on which we think it should be founded. Notwithstanding the high authority of Adam Smith- restrictive covenants are always necessary to the security of the landlord, and in some cases beneficial also to the tenant. Their expediency cannot well be questioned in those parts of the country where an improved system of agriculture has made little progress. A landholder, as¬ sisted by the advice of experienced men in framing these covenants, cannot adopt any easier or less offensive plan for the improvement of his property, and the ultimate ad¬ vantages of his tenantry. Even in the best cultivated dis¬ tricts, while farms continue to be let to the highest re¬ sponsible offerers, a few restrictive covenants cannot be dispensed with. The supposed interest of the tenant is too feeble a security for correct management, even during the eailier part of a lease; and in the latter part of it, it is thought to be his interest, in most cases, to exhaust the soil as much as possible, not only for the sake of immediate profit, but frequently in order to deter competitors, and thus to obtain a renewal of his lease at a rent somewhat less than the lands would otherwise bring. With tenants at will, and such as hold on short leases, restrictive covenants are more necessary than with tenants on leases of 19 or 20 years; but in many instances they are too numerous and complicated, and sometimes even inconsistent with the best courses of modern husbandry. The great error lies in prescribing rules by which a ten¬ ant is positively required to act; not in prohibiting such practices, and such crops, as experience has not sanction¬ ed. I he improved knowledge and the liberality of the age have now expunged the most objectionable of these covenants; and throughout whole counties, almost the only restriction in reference to the course of crops is, that the tenant shall not take two culmiferous crops, ripening their seeds, in close succession. This single stipulation, combined with the obligation to consume the straw upon the farm, and to apply to it all the manure made from its produce, is sufficient not only to protect the land from exhaustion, but to insure, in a great measure, its regular cultivation; for half the farm at least must in this case be always under either fallow or green crops. The only other necessary covenant, when the soil is naturally too weak for carrying annual crops without intermission, is, that a certain portion of the land shall be always in grass, not to be cut for hay, but depastured. According to the extent of this will be the interval between the succession of corn crops on the same fields: if it is agreed that half the farm, for instance, shall always be under grass, there can be only two crops of corn from the same field in six years. In this case, not more than two-sixths being in corn, one-sixth in green crops or fallow, and three-sixths in clovers or grasses, it becomes almost impossible to ex¬ haust any soil at all fitted for tillage. There are few in¬ deed that do not gradually become more fertile under this course of cropping. It is sufficiently evident that other covenants are necessary in particular circumstances, such as permission to dispose of straw, hay, and other crops from which manure is made, when a quantity of manure equal to what they would have furnished is got from other places, and a prohibition against converting rich old grazing lands or meadows into corn-lands. In 2 x 346 AGRICULTURE. Enlarge¬ ment of tarms. Agricul- this place we speak only of general rules, such as are ap- ture. plicable to perhaps nine-tenths of all the arable land of Britain, and such as are actually observed in our best cul¬ tivated counties. For the last four years of a lease the same covenants are generally sufficient, only they require to be applied with more precision. Instead of taking it for granted that the proportion of the farm that cannot be under corn will be properly cultivated, from the tenant’s regard to his own interest, it becomes necessary to take him bound to this effect in express tex'ms ; the object generally being to en¬ able the tenant, upon a new lease, to carry on the culti¬ vation of the lands, as if the former lease had not termi¬ nated. What these additional stipulations should be, must depend in part on the season of the year at which the new lease commences, and in part on the course of crops best adapted to the soil and the particular circumstances of every farm. 3. The enlargement of farms to such a size as admits of arrangements and machinery for saving labour, is the na¬ tural consequence of the progress of agriculture, and the acquisition of capital by cultivators, and becomes, in its turn, the cause of further improvements. We have not room to examine here the various objections to large farms which were urged by Dr Price, Lord Kames, and most of the economical writers of the last century. Much stronger reasons, certainly, than any that have been hither¬ to advanced must be required to justify the interference of the legislature with the rights of the agricultural classes,—with that of a landholder to draw the greatest revenue from his property, and with that of a farmer to extend his concerns as far as his capital and abilities will permit. Even though it should be conceded to Dr Price, that a given extent of land yields a greater produce in the hands of several small farmers than of one great farmer, it still remains to inquire, what part of that produce can be spared for the general consumption,—and whether the labour of these people might not be employed with more advantage than on such minute portions of land as yield, even in the best seasons, little more than food for their own subsistence. In Britain, of which the families employed in agriculture are to those of the whole popula¬ tion only as 1 to 3, and in which the proportion of lands cultivated, or that may be cultivated, is not four acres to every individual, the great object ought certainly to be, to increase the disposable produce of the country for the sup¬ ply of the general population. The grand objection to large farms, that they depopu¬ late the country, is not supported by facts. The popula¬ tion of the country has not only greatly increased since the enlargement of farms, but this increase appears to have been little less than that of the town population. The fact is, the increase of the rural population has been in a greater ratio than that of the towns, in those counties, such as Northumberland, where very large farms abound, and where, indeed, as is usually the case, this state of things is combined with a spirited and productive system of agriculture. Even in Lancashire, the ratio of increase in the 10 years from 1801 to 1811 was only two per cent, in favour of the towns; but no one will ascribe this to the enlargement of farms. The truth seems to be, that wherever agriculture has made the greatest progress, whatever may be the size of farms, the increase of em¬ ployment has been attended with a corresponding increase of population ; and that the ratio of increase has been kept down below that of towns by no other causes than the stationary condition or slow progress of agriculture in some parts, and the, superior allurements of manufactures and commerce in others. It is further to be remarked, that, throughout the whole An of the arable districts of Scotland, the number of people t is proportionally greater on large than on small farms.^ The number of hands required on the former is too great to be lodged in the farmer’s own house ; and therefore, on all such farms, cottages are built for their residence. These Main cottages are generally inhabited by married men, whose hro families find employment in hoeing green crops, and othervanl easy work, from a very early age. In the less-improved counties, on the other hand, where small farms still pre¬ vail, unmarried servants are preferred, as, on such farms, there is little or no employment for the families of mar¬ ried servants. Our limits do not permit us to inquire how far the poor-laws of England operate against the employ¬ ment of married servants, living in cottages on every farm; but the happy effects of this arrangement are manifest in the south-eastern counties of Scotland, as we shall notice immediately. The possession of land is held by some writers to be soCott important, with a view to the comforts of the labouring hnr classes, as well as to the increase of the rural population, that they have not been contented with objecting to large farms, but have proceeded to recommend what are called cottage-farms, for country labourers generally. Of this plan we might say at once, that it must be limited every¬ where by the demand for labour; and that, wherever such small allotments are required by the state of agri¬ culture, they will gradually be formed from motives of interest, without the necessity of any higher control They are at this time common in many parts of Britain; and a different system has been established in other parts, for no other reason than because of its superior advan¬ tages to all concerned. Yet as cottage-farms bear a very plausible appearance in the eye of speculative men, it seems necessary to offer some further remarks on a ques¬ tion which has been so often agitated. If every labourer had a comfortable cottage and four acres of land at a low rent, as recommended by some of the correspondents of the Board of Agriculture, there is reason to believe that his condition might be much im¬ proved for a few years, supposing the demand for labour to continue the same as at present. Even the colonies which this class would every year send forth in quest of new cottages might be supplied for a time; and though the wuges of labour would sink very fast, still this premium might enable the labourers to multiply with little inter¬ ruption for several generations. At last, however, the multiplication of cottage-farms must necessarily stop, and a great proportion of the people, without land and without the means of employment, would either sink into helpless misery, or be driven by despair to the commission of every species of enormity. Such was the state of England at the breaking up of the feudal system, the policy of which also was to increase the number of the people, without regard to the means of their employment; and such, though in a much less degree, is the present state of those parts of the united kingdom in which cottage- farms are the most prevalent. The whole question, we think, is capable of being most satisfactorily decided byr an appeal to the plain mercantile criterion of rent. If a hundred labourers, each of them possessing four acres, can pay a higher rent than one far¬ mer can pay for the whole four hundred, buildings, fences, and repairs being estimated, we can see no reason why they should not be preferred; but if this be not the case, we are greatly at a loss to conceive with what justice landholders can be called upon to submit to sacrifices which no other class of the community is ever expected to make. We might, with just as much reason and jus- AGRICULTURE. y. tice, require a manufacturer to employ a certain number j:., 0f hands in proportion to the amount of his capital, how- V>',“O'ever unprofitable to him might be their labour. In all our best agricultural counties there are two sorts (1^ of of cottages, occupied by two distinct classes of labourers, cutu;rs. Of the first sort are the small agricultural villages, where those mechanics and other labourers reside, who could not find full employment on any one farm. To such men small farms are advantageous, or otherwise, accord¬ ing to the nature and the constancy of their employment. The other class of cottagers, to which we have already alluded, are ploughmen and other servants employed throughout the year on a particular farm. To these men small possessions of land are almost as unsuitable as they would be to a country gentleman’s domestics. But a small garden is usually attached to each cottage ; and they are often allowed to keep a cow as part of their wages, not upon any particular spot of their own, but along with their master’s cows. Their fuel is carried home by their mas¬ ter’s teams; and a part of his own field, ready dressed, is assigned them for raising potatoes, flax, or other crops, for their families. Thus, with little risk from the seasons or markets, and without any other demand on their time than a few leisure hours will satisfy, these people enjoy all the advantages which the occupancy of land can con¬ fer on a labourer. And there is not a more useful, we may also add, a more comfortable, body of men among the industrious classes of society. To give this class of labourers four acres of land along with every cottage, would be to render them bad servants and worse farmers, and either a nuisance to the person on whose farm they reside, or his abject dependents for em¬ ployment. The only proper residence for men who do not choose to engage, or are not wanted as constant la¬ bourers, is in such central agricultural villages as we have just mentioned, and not on separate farms, where they are excluded from the general market for labour. Poonlo. But it has been lately suggested, that our poor soils i might be cultivated by another description of cottagers, ' • with benefit to the public generally, by the improvement of such lands and the diminution of the poor-rates, as well as with profit to those who advance the necessary capital. As far as there has yet been time to judge, some well-di¬ gested and economically executed plans of this kind have been very successful in Holland. The leading points de¬ serving notice in these poor colonies are, the amount of capital sufficient to purchase the land, and to defray the necessary expense of buildings and stock ; its division into farms of seven acres ; the vigilant superintendence exer¬ cised over the colonists, whose operations are almost all performed by manual labour, and much of whose time is employed in collecting manure; their moral and religious instruction; and the surplus produce obtained to replace the original outlay, and afford a permanent clear income or rent in all time coming. The most considerable of these colonies was established at Frederick’s Oord in 1818, at an expense of L.22. 6s. 7d. for every individual; and after a few years’ experience, the annual excess of produce over subsistence for each family was found to be L.8. 2s. 4d. after allowing for a rent of 12s. per acre. The whole out¬ lay, it was calculated, would be replaced in sixteen years. Ihe crops raised are barley, clover, potatoes, rye; and about one acre out of the seven is kept permanently in grass. Ihe only sorts of live stock seem to be cows and pigs. About the end of 1825 the number of colonists compos¬ ing this settlement was 6778, and the population of all the other colonies of this description in Holland was then es- tiirmted at more than 20,000. The founders of one of these, formed near Antwerp in 347 1822, soon after made a contract with government to main- Agricul- tain 1000 mendicants for sixteen years, at the rate of 35 ture. guilders, or L.2. 18s. 4d., for each per annum; and more recently an individual possessing a portion of heath land near Bruges agreed to take another thousand on the same terms. But for a particular account of these colonies we must refer to Jacob’s Tracts on the Corn-Trade and Corn- Laws, 1828. But with regard to the size of farms in the agriculture of this country, we may add, that of all the witnesses ex¬ amined before the committees of Parliament on the corn- laws, there was only one whose sentiments were opposed to the general feeling of all well-informed men, regarding the advantages that have resulted from the enlargement of farms. We shall therefore content ourselves with noticing what appears to be the natural progress in the size of farms,—the circumstances which prevent any pos¬ sible enlargement of them from ever becoming injurious to the public,—and the influence which perfect liberty in this respect has exerted in the improvement of our agri¬ culture. During the feudal system, that part of an estate which Progress was not cultivated under the direction of the proprietor in the size himself, was let out in small allotments to his vassals, from farms* whom he received military or other services, or a portion of the produce, in return. In those times of turbulence and insecurity, the power of the chief mainly depended on the number of his tenants ; and it was therefore his policy to increase them as much as possible, by dividing his land into very small possessions. That they might assist one another in their rural labours, and in repelling the incur¬ sions to which they were incessantly exposed, these tenants were collected in a village near the castle of their lord. A certain extent of arable land was appropriated to it, on which they raised corn, and a much larger tract of waste or wood land, where their live stock pastured in common. Spirited cultivation could never be introduced into this system of occupancy; nothing more than the means of subsistence was sought by the tenantry; and power, not revenue, was the great object of the landholder. For a long time after the fall of the feudal system, this arrangement continued to prevail with little alteration; its vestiges are still to be traced in every part of Britain; and it exists in several counties, though in a modified form, even at the present time. The common fields and commons of England, and the in/ield and outfield divi¬ sions of Scotland, did not originate in any regard for the welfare of the lower classes, to whom the tenancy of land is now thought to be so necessary, but in the anarchy and oppression of those dark ages in which all the land¬ ed property of the island was engrossed by a few great barons. When these petty sovereigns were at last overthrown, and when commerce and the arts held up to them new objects of desire, and to their depressed tenantry new modes of employment and subsistence, the bond which had hitherto connected the landholder and cultivator be¬ came more and more feeble, and it was soon found neces¬ sary to establish it upon other foundations than those oi feudal protection and dependence. The connection be¬ tween landlord and tenant came gradually and generally to assume that commercial form, which is at once most conducive to their own interests and to the general wel- fare. One great obstacle to this change was the want of ca¬ pital ready to be embarked in agricultural pursuits. Un¬ der the feudal system there could be little or no accumu¬ lation. Property in land was the only means of obtaining the command of labour, and a share of the produce its 348 AGRICULTURE. Agricul- only recompense. Accordingly, upon the breaking up of ture. the feudal system, large tracts were taken into the im- mediate possession of landholders themselves, because no suitable tenants could be found. The constant super¬ intendence required in cultivating corn-lands, as well as the absurd restrictions of those times upon the corn- trade, and the constant demand for British wool on the Continent, occasioned these tracts to be laid to grass and pastured with sheep. Hence the grievous complaints, during two centuries, of the decay of husbandry and farm-houses. But this resource of land proprietors was effectual only on soils of an inferior description: on good arable land, the only method by which a part of the produce could reach them in the shape of rent was to enlarge their farms. The old occupiers were too numerous to spare any considerable part of the produce, and generally too indo¬ lent and unskilful to make any great exertions to augment it. In these circumstances the landholder must either have virtually abandoned his property, or reduced the number of its inhabitants, who were no longer permitted by law to make him that return which had been the ori¬ ginal condition of their tenures. But the population of the towns was now gradually increasing, and it was neces¬ sary, for the supply of their wants, as much as for the benefit of the landholders, that a large disposable produce should be obtained from the soil. The measure of enlarg¬ ing farms was, therefore, in every view, indispensable. Even such of the tenants themselves as it was necessary to displace might have felt but a slight and temporary inconvenience had the change been gradual. Some of them would have found employment in towns, and others as hired labourers and artisans in the country. The dis¬ mission of the small tenants seems, however, to have been the occasion of much misery; for, in the sixteenth cen¬ tury, manufactures and commerce had made comparatively little progress in Britain. In the present times, any length to which the private interest of landholders could operate in this manner would, in a national point of view, be too inconsiderable to deserve notice. It is in this way that farms have been enlarged. The most skilful and industrious of these small tenants were naturally preferred, and their possessions afterwards ex¬ tended as their capital increased. The consequence every¬ where has been, a better system of cultivation, affording a higher rent to the land proprietor, and a greater supply of land produce for the general consumption. But it is only for a time, and to a very limited extent, that the enlargement of farms can proceed. The interest of the landlord, which gave the first impulse, is ever vigilant to check its progress, when it is attempted to carry the measure beyond due bounds. It is in this that the security of the public consists, if it were ever possible that the public interest should be endangered by the en¬ largement of farms. Accordingly, in most of our counties, a few tenants, of superior knowledge and capital, have been seen to hold considerable tracts of land, which after a few years were divided into a number of separate farms. The practice of these men is a lesson to their neighbours; and their success never fails to bring forward, at the expiration of their leases, a number of competitors. Whenever skill and capital come to be generally diffused, there can be few instances of very large farms, if a fair competition be permitted. No individual, whatever may be his fortune and abilities, can then pay so high a rent for several farms, each of them of such a size as to give full room for the use of machinery and other economical arrangements, as can be got from separate tenants. The impossibility of ex¬ ercising that vigilant superintendence which is so indis¬ pensable in agricultural concerns, cannot long be compen- At sated by any advantages which a great farmer may pos- t sess. His operations cannot be brought together to one^ spot, like those of the manufacturer; the materials on which he works are seldom in the same state for a few days; and his instruments, animated and mechanical, are exposed to a great many accidents, which his judgment and experience must be called forth instantly to repair. It has been said, indeed, that a great farmer may pay a higher rent, because he saves the family expenses of a number of small tenants. But from what fund do these tenants maintain their families ? It ought to be either from the profits of their capital, or the wages of their labour, or from both combined, and certainly not from the landlord’s just share, in the shape of an abatement of rent. If they can¬ not pay so high a rent, it must be because their capital and labour are less productive to the public tlran those of the large farmer. Such men might, in most cases, be em¬ ployed with more advantage, even to themselves, in some other profession. The various other reasons assigned for the great en¬ largement of farms are equally nugatory. There is gene¬ rally no saving to the landlord in buildings and fences; and a very small difference of rent will pay for the trouble of keeping accounts, and settling with twenty tenants in¬ stead of one. The fact certainly is, that the orincipal, if not the only reason, why farms have been enlarged, is, the higher rent paid by their occupiers. To pay this rent, they must bring to market more produce ; and this they are enabled to do, by the distribution of their crops and live stock to suitable soils and pastures; by an economical arrangement and regular succession of labour throughout the year; by the use of machinery; and, still more than all, perhaps, by the investment of capital in those perma¬ nent improvements which augment both the quantity and value of their products. Rent, in fact, is an almost un¬ erring measure of the amount of the free produce; and there is no better criterion for determining whether a tract of country be laid out in farms of a proper size, than the amount of the rent paid to its proprietors. Their in¬ terest is, in this instance, completely identified with that of the great body of the people. If we examine the various sizes of farms in those dis-Siz tricts where the most perfect freedom exists and the ^ari best management prevails, we shall find them determined,^ with few exceptions, by the degree of superintendence^ which they require. Hence pastoral farms are the largest;0ft] next, such as are composed both of grazing and tillage lands ; then, such rich soils as carry cultivated crops every year; and, finally, the farms near large towns, where the grower of corn gradually gives way to the market-gar¬ dener, cultivating his little spot by manual labour. The hills of the south of Scotland are distributed into farms of the first class ; the counties of Berwick and Roxburgh into those of the second; and the smaller farms of the Lothians and of the Carse of Gowrie, where there seems to be no want of capital for the management of large farms, are a sufficient proof of the general principle which determines the size of farms. It must readily appear from these remarks, in what manner the enlargement of farms, or rather the absence of all restraint upon the transactions of the landholder and farmer, has promoted the improvement of our agriculture. To confine the practice of this important art to the man¬ ual labour of men in a state of poverty and dependence, would be no less injudicious, and much more ruinous in a national point of view, than to destroy all the extraor¬ dinary inventions for saving labour in our manufactures. The effects of capital and machinery are the same in both AGRICULTURE. Atf ul- departments. But no man of education, and in circum- u . stances much above the condition of a common labourer, would ever engage in farming, if his concerns could be no farther extended than to fifty or one hundred acres held at rack-rent; and on such farms there is no room for the most economical machinery,—for convertible husbandry, by which land is preserved in its highest fertility,—or, in¬ deed* for any of those arrangements which approach in their effects to the division of labour in other arts. Besides those general causes of the improvement of the agriculturexof Britain, arising from the division of landed property,—the existence of a distinct class of professional farmers, whose rights are secured by leases, and whose exertions are stimulated by a rent settled by competi¬ tion,—and the opportunities held out for the investment of capital as far as it promises to be profitable,—there are several others of a more limited or temporary nature, but which it is only necessary barely to mention. The most important of these is the extent of the British market, which for many years has required more corn than was grown in the country. The gradual rise of price, which was the necessary consequence of this, and still more the enormous prices during the late war, in which foreign sup¬ plies were obtained with difficulty or altogether withheld, have contributed in no small degree to the improvement of our own ample resources. This has been further pro¬ moted by the facility and expedition with which com¬ modities of every kind are transported by means of canals, roads, and railways. We may add, that the liberal accom¬ modations afforded by the banking establishments during the suspension of cash payments enabled British farmers to operate upon extensive wastes, of which the improve¬ ment must be advantageous in a national point of view, though, in consequence of the change that has taken place since the peace, it may not in many cases have been pro¬ fitable to individuals. Hapn.ro. The progress of a correct system of agriculture is ge- » vi Jre nerally -allowed to have been more rapid in Scotland than in Sc *n England; the effects, at least, have been more conspi- land. cuous- Not only the rents paid in Scotland, but the ac¬ tual produce per acre, and still more the disposable produce, seem to be greater than in England, wherever the comparison is made with land of a similar quality, and with an allowance for the difference in climate and markets. The remark naturally leads us to advert to some circumstances which seem materially to impede the agricultural improvement of the country, particularly the southern part of it; and with one or two observations on tins head we shall conclude this article. The low state of agriculture in many parts of Britain, with the advance in the price of corn, on the one hand, and the abundance of capital displayed in the manufac¬ tures and commerce of the country, on the other, are cir¬ cumstances sufficient to convince every reflecting mind iat there is no want either of means or of induce¬ ments to the improvement of our territory. It is im¬ possible, indeed, to travel through the country in any section, without feeling a strong conviction that there must be some serious obstacles to the investment of 349 capital in agriculture. The circumstances which seem Agricul- to have the most weight in determining men of capital ture. to engage in any particular profession, are, the security and productiveness of that capital, the power of trans¬ ferring it, and the degree of estimation in which the profession is held by the public. To the absence of these essential requisites we must ascribe the backward state of this art, notwithstanding all the other motives, both of a public and private nature, which have long existed for its advancement. To the class of drawbacks upon agriculture, and impe¬ diments to its improvement, belong tithes, poor-rates, payments in the shape of fines, and services exacted by the lords of manors; entails ; tenancy at will, or on very- short leases; unfair restrictions on the tenant as to the disposal of his lease, and as to the management of the lands during its currency ; the game-laws ; and the com¬ plicated regulations under which commons and common fields are cultivated, and the great expense required to place them in a state of severalty. It appears that nearly three-fourths of the lands of England and Wales are exposed to claims which wrest from the husbandman one-tenth of the gross produce of his labour and capital, and this whether the remainder of the produce be or be not sufficient for his remuneration. Though no rent were paid for poor soils, this burden alone would effectually prohibit their correct cultivation; and even in the case of rich soils, tithes diminish the rent so considerably as to make it the interest of landholders, in many parts of England, to restrain their tenants from con¬ verting grass-lands into tillage ; that is, from placing them under the most productive management for the community, both in regard to the supply of food and of employment. To the enlightened inquirer it must appear abundantly Nothing clear, that all plans for the extension and improvement of required British agriculture must prove ineffectual so long as these but tbe re* capital obstacles are left untouched; and that their re-11?0^1!0^ moval is all that need be done, and all that ought to be° s ac ^ done by a wise government, for securing an abundant supply of the first necessaries of life. Let all land be held and occupied in severalty; let it be exempted from all indefinite exactions, particularly such as diminish or altogether absorb the just returns of capital and indus¬ try; let the connection between the land proprietor and the farmer be everywhere formed upon equitable principles, to the exclusion of all remnants of feudal ideas, all notions of favour and dependence, and all obligations that do not appear in the lease itself, or are not imposed by the gene¬ ral principles of law; let the rights of a tenant be so far enlarged as that he may be enabled to withdraw his capital by a transference of his lease, and to regu¬ late the succession to it after his death; then there can be little doubt that a large part of the disposable capital of the nation, now embarked in much less pro¬ fitable pursuits, would of its own accord turn towards the improvement of our lands, and thus furnish em¬ ployment and subsistence for our population, secure from the caprice of fashion and the rivalry and jealousy of other countries.

Plate YIII. Fig. 1 represents a profile of Mr Smith's Reaping-Machine, Sm complete and in operation. It will be seen by this figurerea and fig. 2 (which is a bird’s-eye view of the machine), thatma‘ the horses are yoked one on each side of a pole, which runs back from the frame of the carriage. The person who drives the horses and directs the machine walks behind, having command of the horses by a set of common plough- reins, and directing the machine by a hold of the end of the pole. The horses draw from a cross bar at the end of the pole by common plough chains, the back-weight of the carriage resting on their common cart-saddles hy means of an apparatus such as is used in curricles. On the fore part of the carriage is hung a horizontal circular cutter, surmounted by a drum, the blade of the cutter projecting inches beyond the periphery of the lower end of the drum. When the carriage is moving forward, a rapid ro¬ tatory motion is communicated to the cutter and drum, from the motion of the carriage-wheels, by means of a series of wheels, pinions, and shafts. The diameter of the cutter projects beyond the carriage-wheels on each side, so as to cut a breadth sufficient to. allow the carriage and horses to pass along without risk of treading down the un¬ cut corn. The corn being cut by the rapid motion of the cutter, the lower ends rest upon the blade of the cutter, and the upper parts coming in contact with the drum, the AGRICULTURE. - .1. whole is carried round, and thrown off in a regular row at wri the side of the machine. The lower ends taking the ./v-'Vround first, the heads fall outwards, the stalks lying pa¬ rallel to each other, and at nearly a right angle to the line of motion of the machine. The corn lying thus in regular rows, is easily gathered into sheaves by the hand, or by a rake, fork, or other convenient instrument, and is bound in the usual way. Minute Description of the Plate. Fig. 2. A, the frame of the carriage, made of oak or other strong wood, and put firmly together by bed-bolts screwed into the cross bars B. C, the pole, made fast to the cross bars. D, a cross bar, at the extremity of the pole, from which the horses pull; this bar is of iron, in order to give sufficient weight on the horses’ backs. E, the carriage-wheels, 5 feet in diameter, and 6 inches broad in the tread. F, the cutter, 5 feet 4 inches in diameter, composed of six segments bolted to an iron ring, inch broad and £ inch thick, which ring is connected to the foot of the upright spindle by the cross arms, G.—-Fig. 6 shows one of these segments on a larger scale: a is of hard wood, 3^ inches broad and 1 inch thick ; bb axe of German steel, and of a scythe temper, 3|- inches broad, and inch thick at the back; they overlap the wood, to which they are rivetted, inch, their upper side being flush with the wood; d, holes through which the ring-bolts pass. _ Fig. 5 is a transverse section of fig. 6 II,' fig, 2, a conical drum of slight tin-plate or basket-work, whose lower periphery is 5 inches within the edge of the cutter, but whose upper periphery extends as far as that of the cutter. This drum is two feet deep, connected to the same ring with the cutter below, and to the spindle above by another ring, with four arms. The drum is covered on the outside with canvass, on which perpendicular strips of soft rope are sewed, being one inch thick, and three or four inches apart: these give sufficient friction to carry round the cut corn, whilst, from their softness, they have no tendency to shake or thresh it. The horses are yoked to the cross bar, D, by common plough-chains. The breeching-chains are linked to the draught-chains, and a breast-chain, which passes through a ring made fast to the names, is drawn up to an eye at N. Fig. 4 is an inside view of the naves of the carriage-wheels; a, a tranverse section of t ie axle; b, a ratch-wheel, made fast on the square of the axle; c, catches, movable on pivots, made fast to the nave ; «) slight springs to keep the catches in gear. By this means the wheels carry the axle in revolution with them " ien the carriage is moved forward, but move round upon it when the carriage is drawn in a contrary direc¬ tum. lids construction is necessary to facilitate the turning of the machine. The axle moves in two cast-iron seats with caps, on which the frame of the carriage rests. A wheel, o (fig. 2), 0f 24 teeth of inch pitch, works m o an intermediate wheel of the same dimensions. This " ieei is m gear of a pinion of 12 teeth, fast on the end ! , 7 If cross shaft Q. At the centre of this shaft, two '|fve e wheels, 11, with long sockets, are fitted loose. lose wheels have each 28 teeth of 1A inch pitch : in the .ir °i . ese a double reversing catch, which will be explained by reference to fig. 3, which is a longitudinal ecion °t cross shaft with the wheels and catch; kL 9e f . ; pinion; c, the bevelled wheels, 11, of Jm'.w aVIni8 spekets fitted loose on the shaft; d, a Jut i’G cat?h> which is movable longitudinally on the shaft, thPr * carriectIn revolution with it, by means of the fea- n th e> U^n , shaft, fitted into a corresponding groove if tho CKtC V catch can be put into gear of either wneels at pleasure, by means of the lever, s^fig. 2), movable on a stool at T, and kept to its place when set, by notches in an iron stand at U. Both of the wheels are constantly in gear of a pinion of 14 teeth, V (fig. 2) and/ (fig. 3). By thus reversing the gearing, the cutter and drum can be made to revolve to the rio-ht or left and consequently will throw the cut corn to°either side’ of the machine at pleasure. On the opposite end of the shaft, W (fig. 2), on which the pinion V is fixed, is a bevelled wheel X of 28 teeth, in gear of a pinion of 14 teeth on the upright axle, (fig. 7 and 8). The velocity is so raised by these wheels and pinions, that the. cutter makes 128 revolutions per minute when the machine moves at the rate of 2f miles per hour, the edge of the cutter passing through 32 feet per second. The upright spindle, shown in fig. 1 and 8, has three bearings, one in a brass bush fixed in an iron stay-frame, b ; a second bearing in a wooden bush with a cap on the front of the cross bar at c; and a third in a socket rest¬ ing on the small wheels, d. These wheels serve to keep the cutter always at an equal height from the ground. The particular construction of these wheels, with "that of the frame and socket, will be better understood by refer- ence. to fig. 7 and 8. Fig. 8, a perpendicular section of the foot of the upright spindle and socket; a, the spindle; b, the socket; c, a groove in the spindle, into which the points of two screw pins, d, passing through the sides of the socket, are fitted. These are necessary to keep the spindle in its place, and to bear up the wheels when the spindle is raised. Fig. 7 is a bird’s-eye view of the wheels and carriage, with a transverse section of the socket and spindle; a, the wheels, 14inches in diameter, and 3 inches broad; b, the axle, to which is fastened an iron frame, c, movable on a pivot on the point of the iron bar, f and in a socket at e; the bar/is one inch square, having a long ruff at p, which is turned and fitted to the eye, e, of the socket, fig. 8. The bar is bent so as to pass close under the cutter, and runs up to the pole. This bar is necessarv to relieve the point of the upright spindle of the resistance opposed to the wheels in moving along. The cutter can be placed higher or lower on the spindle, so as to cut the straw to any height, by means of a series of holes through the spindle; pins passing through holes in the sockets of the arms, and the most suitable of the series. The cutter can also be screwed to any height from the ground, from two to eighteen inches, by means of an iron lever, on the point of which is a brass socket, in which the upright spindle runs, and on which it rests. The lever is hung by an iron chain passing over a pulley at / and joining two iron rods at ft, which connect it with a screw box, I, which is moved backwards and forwards, by turning round the screw, m. To the end of this screw is connected an iron rod, which runs along the upper side of the pole to a bear¬ ing at h. At the end of this rod is a winch, o, of 9 inches radius, by which the person who guides the machine can turn round the screw, and so raise or lower the cut¬ ter at pleasure. This is principally of use to raise the cutter when passing over a deep furrow, or in going from one field to another. P is a hollow piece of wood put upon the end of the rod, by which the man holds with one hand when guiding the machine. In most cases the cutters will cut ^ of an acre without requiring to be sharpened, which can be done in two minutes by a common scythe- stone, two of which are conveniently carried in two leather pockets, q, fig. 2. When it is necessary to go with the machine to a distance, the upright spindle, with the drum and cutter, are taken from their place, and placed on the top of the carriage; and the small wheels are drawn close up to the cross bar. The draught bar, D, is taken from the end of the pole and placed near the frame 351 Agricul¬ ture. 352 AGRICULTURE. Agricul- of the carriage.

Plan of a Threshing-Machine, to be driven by machine water, or by four horses occasionally when there is not a worked by constant supply of water, with the new-invented appara- wafer3 °r tUS f°r horSCS. A, the perpendicular axle (see A, fig. 2), in which are fixed the arms or levers D, that carry the great wheel B ; and upon these arms are fixed the limbers, by which the cattle pull the machine when threshing. No. 1 and 2 represent two frames fixed in the axle A, and support¬ ed by the arms D ; upon these frames are placed the two shifting-blocks, as 3 4 and 5 6, which have liberty to move or slide, either inwards to the axle or outwards from it. In each of these shifting-blocks are placed two running sheeves or whorles. F F, an endless chain or rope, which passes over the two sheeves that are placed in the shift¬ ing-blocks at the ends 4 and 5. By this chain the two blocks are so connected, that if the one is pulled outwards from the axle A, the other is pulled inwards alternately. 15 and 15 are two sheeves, by which the chain F F is kept clear of the axle A when turning round. Y Y are two ropes that pass over the sheeves which are placed in the shifting-blocks at their ends 3 and 6: upon each end of these ropes is fastened a small block, in which are placed the running sheeves 7, 8, 9, 10, and over these sheeves pass the double ropes, by which the horses pull when working this machine, a, h, c, d, e,f and g, h, represent the limbers or ears, fixed by screw-bolts on the arms D D D D (see D D D in fig. 2), and in each of these ears are placed two running sheeves, by which the ropes are conveyed to the line of draught (see 1 and 2 in fig. 2); each horse is yoked to the ends of the chains or ropes, as at 11, 12, 13, and 14, these ropes passing over the sheeves 7, 8, 9, 10, which turn on their axis. By this means the draught will always press the collars equally upon the horses’ shoulders; and though they are walk¬ ing in a circle, yet the strains of the draught must press fairly or equally on their shoulders, without twisting their body to either side. This advantage cannot be obtain¬ ed in the common way of yoking horses in a threshing- machine, unless the draught-chains on each side of the horse be made in exact proportion in length to the dia¬ meter of the circle in which he walks, or the chain next to the centre of the walk made a little shorter than the one farthest from it, which is often neglected ; but in this way of yoking the horses the strain of the draught will naturally press equally on his shoulders when pulling, which of course must be less severe on the animal when walking in a circle. Thus, the draught-chains, or ropes, being all connected by means of the endless chain F F, and the shifting blocks, with their sheeves, having liberty to move either inwards to the axle A, or recede from it, it is apparent, that if one of the horses relax, the other horse will immediately press the col¬ lar hard to his shoulders, and excite him to exertion. For instance, if the horse hooked to the draught-chains at 12 were to relax, then the one yoked at 14 would instantly take up his chain, and pull the collar close to his shoulders ; so that the horse at 12 must either exert himself or be pulled backward. And, supposing the horses at 12 and 14 were both to relax, then the exertions of the horses at 11 and 13 would immediately pull the shifting block from 5 to¬ wards 3, and of course press the collars hard on the horses at 12 and 14, which would tend to drag them back¬ ward, and by this means push them to exertion. Thus, j the horses being all connected by the draught-chains and shifting-blocks, their exertions are all united completelyv round the circle, so as to form one power applied to the machine, instead of as many independent powers as there are horses employed when yoked in the common way. It may sometimes be convenient to employ fewer horses than the whole number of which the machine admits. This is easily accomplished; for example, wrere the horse at 12 to be left out, then the two chains must be fastened or tied to the ears c d, and thus the horse at 12 is left out of the circle, whilst the horses at 11, 13, and 14, are never- theless still united, so as to make one combined power act on the machine. This apparatus is the invention of Walter Samuel, an ingenious blacksmith at Niddry, in the county of Linlithgow.

These rollers are generally made of cast-metal, the circumference of the one being smooth, and of the other fluted, or having small teeth its whole length, in order to keep hold of the unthreshed corn; and as they revolve on their pivots, they feed the grain regularly for¬ ward, to receive the strokes from the threshers, by which the corn is detached from the straw.

Figs. 6 and 7. The Odometer. The wheel A is made of light iron, and measures two yards in circumference, being divided by six spokes into feet. One spoke must be painted white. The handle B is divided at C like a fork, and embraces each end of the axis by its elasticity. Through the axis is a hole, into which the end H of the way-wiser fits, and is held fast by a nut D. _ ^ i. • i. , The way-wiser consists of a frame F G, r being hol¬ low to receive a perpetual screw H, a part of which is visible near the index M. At the other end of the screw is a nut I, which keeps it in its place. The screw tuins two brass concentric cogged wheels K and L; K conceals the scale of L, except where a piece is cut out, leaving an index at the beginning of the scale of K, and which, in the drawung, points to 78 of L. The scale of K is numbered towards the left, and that of L to the right. The wheel K has 100 cogs or teeth, and L 101; con¬ sequently, as the same endless screw turns both wheels, it is evident that when K has made a complete revolution of 100 teeth, L will also have made a revolution of 100 teeth ; and the index of K will point to 1 of L, because L has 101 teeth. After a second revolution, it will point to 2, and so on ; the number it points to marking the num¬ ber of revolutions, each revolution showing 100 turns o the iron wheel A. rr inn Accordingly, A measures six feet, or 1 turn; is. 1W times 6 feet, or 600 feet, or 1 revolution; and L 101 times 600 feet, or 60,600 feet, equal to nearly 11^ English miles, the range of the instrument. 880 turns of this wheel make a mile. It is advisable always to commence with the way-wiser set at 0 or zero. To do this, take out the screw' * e centre, when the brass wheels K and L can both be set at zero, and the screw replaced. Set the wheel A upon the ground, with the white spoke undermost, and fax tfae way-wiser into the wheel by means of the nut D, alwajs observing to put it on the left side, as shown in the p ate At any period of measuring, you can tell exactly how far you have gone, and proceed without again setting e way-wiser at 0. vr o t the Suppose, as in the drawing, the spoke No. 4 at ground, the index M pointing at 26 of K, and the in of K pointing at 78 of L; then the distance measureu is 7826 turns of A and two feet; and as A measures yards, 7826 X 2 = 15652 yards, to which add the tw In reading off, particular care should be taken ahvaysto read the large figures (viz. those on the wheel L) hrSt> , afterwards to add the small figures (viz. those on t ie w ^ K) ; and if the figures on K amount to less than > must be prefixed, so that K shall always show two g for instance, L being at 46, and K at 4, the sum,is/,g The easiest way to guard against error, is to read AGRICULTURE.

A B represent the two •ends of the spring to which the plough and horses are yoked, C is a small bar with one of its ends turning tight on a round axis D, and the other end E pushes round the index F, which points out the number of stones (of 14 lbs.) on the index plate G. ~ Plate X. Hum jill- Fig- 1 and 2 are two elevations of a Bone-mill, the first being taken in front, to show the water-wheel and the length of the rollers, and fig. 2 at the end, to show the bones passing through the rollers. The water-wheel, A A, is represented as being of the over-shot kind; it is in¬ cluded between the two walls, B B, upon the top of which, the pivots or gudgeons of its axis are supported in brass bearings. A square formed on the end of one of the gud¬ geons is received into a square socket at the end of the connecting axis, D, which communicates the motion to the lowest, F, of the two rollers, the latter having a similar square on the end of its axis, to be received into the socket at the end of the connecting axis, D. The rollers are supported by a wooden frame, G G. Two iron frames, HH, are bolted down upon it, having grooves or open¬ ings in them, of nearly the whole length, to receive the brasses for the pivots of the rollers, as shown in fig. 2. At the upper ends of these grooves are screws, h h, by which the rollers can be made to act at a greater or less distance from each other, as the size of the bones which are to pass through them may require. Two pinions, k l, are placed upon the ends of the axles of the two rollers, and by their teeth acting together, they compel the two rol¬ lers to accompany each other. The surfaces of the rol¬ lers are filled with indentations and strong teeth, which penetrate and break the bones to pieces. This is accom¬ plished by employing separate cast-iron wheels, placed side by side upon an axis, to compose the rollers; the wheels have coarse teeth, similar to those of a saw or ratchet-wheel; each wheel of the lower roller, F, is an inch thick, and they are placed at distances of an inch and a half asunder, having circles of hard wood or iron placed between them, which are two inches less in diame¬ ter. Thus they leave grooves between the toothed wheels, which have the effect of rendering the teeth upon the sur¬ face of the roller insulated. The wheels of the opposite roller, E, are inch wide, and the spaces between them only 1 inch; and the two are so situated with respect to each other, that the teeth upon one are opposite to the spaces between the teeth of the other, as is clearly ex¬ plained by the figure. A hopper, 11, is fixed above the machine, over the rollers, and into this the bones are filled, so that they rest upon the two rollers, and are drawn in bv their motion, the teeth penetrating and breaking every piece, however large or solid it may be. The bones should be supplied rather gradually to the machine at first, to avoid choking it, and the rollers should then be adjusted to a considerable distance asunder ; but when the bones have once passed through in this way, the rollers are screwed closer by the screws, h h, and the fragments ground a second time. This will generally be found suffi¬ cient, as it is not advisable to reduce the bones to a state of extreme division. The pinions,must have deep cogs, to enable them to take deep hold of each other, when the rollers are set at only half an inch distance to grind fine, mid without the cogs being liable to slip when the centres me separated, so far as to leave a space of 1 inch, or 1^ inch, between the rollers, for the passage of the large bones the first time. The rollers will act most effectually if the different wheels are fixed upon their axles in such a Agrieul- position that the teeth will not cori'espond, or form lines ture- parallel to the axes, and then no piece of bone can escape without being broken by some of the teeth. The bones which have passed through the rollers slide down the in¬ clined board, R, and collect at the bottom in a large heap. When all the stock of bones is thus coarsely broken, a labourer takes them up in a shovel, and throws them again to the hopper, to be ground a second time. Fig. 3. A Machine for grinding Potato-flour.—A, a Machine cylinder covered with tin-plates, pierced with holes, so asforSnnd- to leave a rough surface, in the same manner as the gra-^^P^f* ters used for nutmegs, &c. but the holes in this are larger. This cylinder is situate beneath a hopper, B, into which the potatoes are thrown, and thence admitted into a kind of trough, C, where they are forced against the cylinder, which, as it revolves, grinds the potatoes to a pulp. Mo¬ tion is given to the machine by a handle fixed upon the end of the axis of the grating cylinder, A; and on the oppo¬ site extremity of this axis is a fly-wheel, D, to regulate and equalize the movement. The potatoes, when put into the hopper, press by their weight upon the top of the cy¬ linder ; and, as it revolves, they are in part grated away. On one side of the lower part of the hopper is an opening, closed or opened, more or less at pleasure, by a slider, d; and the degree of opening which this has regulates the passage of the potatoes from the hopper into the trough, C. This is as wide as the length of the cylinder, and has a concave board, R, fitted into it, which slides backwards and forwards by the action of levers, a, fixed to an axis ex¬ tended across the frame of the machine; and a lever, N, is fixed upon this axis, and carries a weight which acts upon the board, R, by means of the levers, to force or press for¬ wards the potatoes contained in the trough C against the cylinder, and complete the grating of them into a pulp. The tin-plate covering the cylinder is of course pierced from the inside outwards, and the bur or rough edge left round each hole forms an excellent rasping surface. Fig. 4. A Potato-Scoop.—A, the end of the handle, Patato- having a round stem, which passes through a piece of me- SC00P- tal, D, and has then a semicircular knife or cutter, E, fixed to it. This is sharp on both edges, and turns upon a pi¬ vot, fitted in a similar piece of brass to D, which, as well as the latter, is formed out of a piece of plate, B C. This forms a shield to hold the instrument firm upon the potato, by placing the thumb of the left hand upon the shield, B C, and pressing the points of D into the root, which is grasped in the hand; then, by turning the handle half round with the right hand, the semicircular knife makes a sweep, and cuts out a piece or set, which is a segment of a small sphere. Fig. 5 is an end view of the shield, B C, and the knife, E, also the piece of brass, D, placed upon the surface of a potato, F, in which the dotted line F G shows the piece the knife will cut out by its mo¬ tion. The only attention necessary in the use of this tool is, that it be placed upon the potato, with the eye or part from whence the shoot springs in the centre of the semicircle of the knife, when it is laid flat upon the root. The advantage of this scoop, besides that it is very quick in its operation, is, that the pieces, being all of one exact size, which is about one inch diameter, they can be planted, by a bean-barrow or drill-machine, with much less la¬ bour and more accuracy than by the hand.

Here, by liftino' UD the hinder part of the machine by means of its handles the contents are left on the ground, and the machine pro- 4 ceeds to a fresh hillock.

E. lat. 19. 4. N. AGRIGENTUM, in Ancient Geography, a city of Si¬ cily, part of the site of which is now occupied by a town called Girgenti, from the old name. See Girgenti. According to ancient authors, Daedalus, the most famous mechanician of fabulous antiquity, fled to this spot for protection against Minos, and built many wonderful edi¬ fices for Cocalus, king of the island. Long after his flight, the people of Gela sent a colony hither 600 years before the birth of Christ, and, from the name of a neighbour¬ ing stream, called the new city Acragas, whence the Ro¬ mans formed the word Agrigentum. These Greeks con¬ verted the ancient abode of the Siculi into a citadel to guard the magnificent city which they erected on the hillocks below. An advantageous situation, a free govern¬ ment with all its happy effects, and an active commercial spirit, exalted their commonwealth to a degree of riches and power unknown to the other Greek settlements, Sy¬ racuse alone excepted. But the prosperity of Agrigentum appears to have been but of short duration, and tyranny soon destroyed its liberties. Phalaris was the first who reduced it to slavery. His name is familiar to most readers on account of his cruelty, and the brazen bull in which he tortured his enemies. See Phalaris. Pha¬ laris met with the common fate of tyrants, and after his death the Agrigentines enjoyed their liberty for 150 years ; at the expiration of which term Thero usurped the sovereign authority. The moderation, justice, and valour of this prince preserved him from opposition while living, and have rescued his memory from the obloquy of poste¬ rity. He joined his son-in-law Gelo, king of Syracuse, in a war against the Carthaginians; in the course of which victory attended all his steps, and Sicily saw herself for a time delivered from her African oppressors. Soon after his decease, his son Thrasydeus was deprived of the dia¬ dem, and Agrigentum restored to her old democratical government. Ducetius next disturbed the general tran¬ quillity. He was a chief of the mountaineers, descen¬ dants of the Siculi; and was an overmatch for the Agri¬ gentines while they were unsupported by alliances, but sunk under the weight of their union with the Syracusans. Some trifling altercations dissolved this union, and pro¬ duced a war, in which the Agrigentines were worsted, and compelled to submit to humiliating terms of peace. Resentment led them to embrace Avith joy the proposals of the Athenians, then meditating an attack upon Syracuse. Their new friends soon made them feel that the sacrifice of liberty and fortune would be the price of their protec¬ tion, and this consideration brought them speedily back to their old connections. But, as if it had been decreed that all friendship should be fatal to their repose, the recon¬ ciliation and its effects drew upon them the anger of the Carthaginians. By this enemy their armies were routed, their city taken, their race almost extirpated, and scarce a vestige of magnificence was left. Agrigentum lay 50 years buried under its own ruins, when Timoleon, after triumphing over the Carthaginians, and restoring liberty to Sicily, collected the descendants of the Agrigentines, and sent them to re-establish the dwellings of their fore¬ fathers. Their exertions were rewarded with astonishing success; for Agrigentum rose from its ashes with such a renewal of vigour, that in a very short time we find it engaged in the bold scheme of seizing a lucky moment, when Agathocles and Carthage had reduced Syracuse to the lowest ebb, and arrogating to itself supremacy over all the Sicilian republics. Xenodicus was appointed the leader of this arduous enterprise ; and had his latter ope¬ rations been as fortunate as his first campaign, Agrigen¬ tum would have acquired such a preponderance of repu¬ tation and power, that the rival states would not have even dared to attack it. But a few brilliant exploits were succeeded by a severe overthrow; the Agrigentines lost courage, disagreed in council, and humbly sued for peace to Agathocles. This commonwealth afterwards took a strong part with Pyrrhus, and, when he left Sicily to the mercy of her enemies, threw herself into the arms of Carthage. During the first Punic war Agrigentum was the headquarters of the Carthaginians, and was besieged by the Roman consuls, who, after eight months’ blockade, took it by storm. It nevertheless changed masters seve¬ ral times during the contest between these rival states, and in every instance suffered most cruel outrages. After this period very little mention of it occurs in history, nor do we know the precise time of the destruction of the old city and the building of the new one. See Girgenti. The hospitality and parade for which the Agrigentines are celebrated in history were supported by an extensive commerce; by means of which, the commonwealth was able to resist many shocks of adversity, and always to rise again with fresh splendour. It was, however, crushed by the general fall of Grecian liberty; the feeble remnants of its population, which had survived so many calamities, were at length driven out of its walls by the Saracens, and obliged to lock themselves up for safety among the bleak and inaccessible rocks of the present city. The principal part of the ancient city lay in the vale; the present town, called Girgenti, occupies the mountain on which the citadel of Cocalus stood. The whole space comprehended within the walls of the ancient city abounds with traces of antiquity, foundations, brick arches, and little channels for the conveyance of water ; but in no part are any ruins that can be presumed to have belonged to places of public entertainment. This is the more extra¬ ordinary, as the Agrigentines were a sensual people, fond of shows and dramatic performances, and the Romans A G R iia never dwelt in any place long without introducing their savage games. Theatres and amphitheatres seem better Apia, calculated than most buildings to resist the outrages of ^^time; and it is surprising that not even the vestiges of their form should remain on the ground. AGRIONIA, in Grecian Antiquity, festivals annually celebrated by the Boeotians in honour of Bacchus. At these festivals the women pretended to search after Bac- dius as a fugitive, and, after some time, gave over their inquiry, saying that he had fled to the Muses, and was concealed among them. AGRIOPHAGI, in Antiquity, a name given to those who fed on wild beasts. The word is Greek, being com¬ pounded of ayyoi, wild, savage, and payw, I eat. The name is given, by ancient writers, to certain people, real or fabulous, said to have fed altogether on lions or pan¬ thers. Pliny and Solinus speak of Agriophagi in Ethi¬ opia, and Ptolemy of others in India on this side the Ganges. AGRIPPA, Cornelius, born at Cologne in 1486, a man of considerable learning, and by common report a great magician; for the monks at that time suspected every thing of heresy or sorcery which they did not un¬ derstand. He composed his treatise of the Excellence of Women to insinuate himself into the favour of Margaret of Austria, governess of the Low Countries. He accept¬ ed of the charge of historiographer to the emperor, which that princess gave him. The treatise of the Vanity of the Sciences, which he published in 1530, enraged his enemies extremely; as did that of Occult Philosophy, which he printed soon after at Antwerp. He was imprisoned in France for something he had written against Francis L’s mother; but was liberated, and went to Grenoble, where he died in 1534. Agrippa, Herod, the son of Aristobulus and Mariam- ne, and grandson to Herod the Great, was born in the year of the world 3997, three years before the birth of our Saviour, and seven years before the vulgar era. After the death of Aristobulus his father, Josephus informs us that Herod his grandfather took care of his education, and sent him to Rome to make his court to Tiberius. The emperor conceived a great affection for Agrippa, and placed him near his son Drusus. Agrippa very soon won the graces of Drusus, and of the empress Antonia. But Brusus dying suddenly, all those who had been much about him were commanded by Tiberius to withdraw from Rome, lest the sight and presence of them should renew his affliction. Agrippa, who had indulged his inclination to liberality, was obliged to leave Rome, overwhelmed with debt, and in a very poor condition. He did not think it fit to go to Jerusalem, because he was not able to make a figure there suitable to his birth. He retired therefore to the castle of Massada, where he lived rather hke a private person than a prince. Herod the tetrarch, ms uncle, who had married Herodias, his sister, assisted him for some time with great generosity. He made him principal magistrate of Tiberias, and presented him with a large sum of money; but all this was not sufficient to answer the excessive expenses and profusion of Agrippa ; M) tllat Herod growing weary of assisting him, and re¬ proaching him with his bad economy, Agrippa took a re¬ solution to quit Judea, and return to Rome. Upon his ani'cil he was received into the good graces of Tiberius, an commanded to attend Tiberius Nero, the son of Dru- sus. Agrippa, however, having more inclination for Caius, m son of Germanicus, and grandson of Antonia, chose ra ier to attach himself to him; as if he had some pro- P ic ic views of the future elevation of Caius, who at that ‘me was Reloved by all the world. The great assiduity A G R 357 arid agreeable behaviour of Agrippa so far engaged this Agrippa. prince, that he kept him continually about him: Agrippa being one day overheard by Eutyches, a slave whom he had made free, to express his wishes for Tibe¬ rius’s death and the advancement of Caius, the slave be¬ trayed him to the emperor ; whereupon Agrippa was loaded with fetters, and committed to the custody of an officer. Tiberius soon after dying, and Caius Caligula succeeding him, the new emperor heaped many favours and much wealth upon Agrippa, changed his iron fetters into a chain of gold, set a royal diadem upon his head, and gave him the tetrarchy which Philip the son of Herod the Great had been possessed of, that is, Batanaea and Tra- chonitis. To this he added that ofLysanias ; and Agrip¬ pa returned very soon into Judea to take possession of his new kingdom. Caius being soon after killed, Agrippa, who was then at Rome, contributed much by his advice to maintain Clau¬ dius in possession of the imperial dignity, to which he had been advanced by the army. But in this affair Agrippa acted a part wherein he showed more cunning and address than sincerity and honesty; for while he made a show of being in the interest of the senate, he secretly advised Claudius to be resolute, and not to abandon his good for¬ tune. The emperor, as an acknowledgement for his kind offices, gave him all Judea and the kingdom of Chalcis, which had been possessed by his brother Herod. Thus Agrippa became of a sudden one of the greatest princes of the East, and was possessed of as much, if not more territories than had been held by Herod the Great, his grandfather. He returned to Judea, and governed it to the great satisfaction of the Jews. But the desire of pleasing them, and a mistaken zeal for their religion, indu¬ ced him to commit an unjust action, the memory of which is preserved in Scripture, Acts xii. 1, 2, A G U J-Arr; i. an office of higher dignity, and of more various and ex¬ seal tensive duties, than that of advocate-general. He filled ✓v-'this office for seventeen years with the most splendid re¬ putation ; adding, by his lenity in criminal cases, and by his care of the public hospitals, the praise of humanity and benevolence to his other claims to the respect and admira¬ tion of his countrymen. The political philosopher of the present day will probably, however, be inclined to ques¬ tion the justness of the encomiums bestowed upon his exertions during the severe scarcity of 1709; on which occasion he appears to have instituted the most rigorous proceedings against those who were held up as enemies of their country and of mankind, under the names of fore- stallers and monopolists. But, in alluding to this part of his conduct, it may be proper to mention, that his opposi¬ tion, at an after-period, to the delusive projects of the famous John Law, and his elaborate treatise upon the sub¬ ject of Monei/ ( (Euvres, tom. x.), afford undeniable proofs of the soundness of his views in regard to some of the most important doctrines of political economy. It had been early predicted of D’Aguesseau, that he would one day fill the place of Chancellor; and this pre¬ diction was at length realized in 1717, upon the death of Voisin, who then held the seals. Though he was yet only forty-eight years of age, his nomination to this high dignity gave general satisfaction, and wTas, indeed, intended as a popular measure by the duke of Orleans, who had lately assumed the regency. His brother Val- jouan, a man of abilities, but slothful and a humourist, was the only person who refused to congratulate him on the occasion. “ Rather you than I, brother,” was his remark when the new chancellor hastened to him to announce his appointment. In fact, D’Aguesseau soon began to ex-, perience the difficulties and perils attendant upon his ele¬ vation ; for he had not been installed above a year, when he was deprived of the seals, and exiled to his estate. His steady opposition to the extravagant projects of Law, with which the regent and his ministers were wholly intoxicated, was the honourable cause of this first reverse of fortune. In 1720, when the ruinous consequences of these schemes had filled the nation with distress and alarm, the chancel¬ lor was recalled from banishment; and he contributed not a little, by the firmness and sagacity of his counsels, to calm the public discontents, and repair the mischiefs which had been committed. Law himself had acted as the messenger of his recall; and it is said that D’Aguesseau’s consent to re-accept the seals from the hand of this adventurer was much blamed by the literary corps, with which he had hitherto stood in high favour, as well as by the parliament. But his repu¬ tation appears to have sustained a much severer shock, when he endeavoured to prevail with the latter body to register the declaration of the late king in favour of the bull Unigenitns,—a measure which they held in great abhorrence, and which he had himself firmly opposed during the life of Louis. The regent's favourite, Dubois, then archbishop of Cambray, had moved his master to insist upon this act of registration, in the hope that he might thereby obtain a cardinal’s hat; and it seems ,to ‘Iave been thought that the chancellor had yielded as better opinion in compliance with the wishes of this woitaless minion. Be this as it may, it is certain that he opposed the favourite with firmness, when he attempted, u ter being made prime minister, to take precedence in ie council; and he was in consequence, in 1722, sent a second time into exile. He now passed five years on his estate at Fresnes; and io a ways spoke with delight of this tranquil period, when e Was 'e^ free from the cares of professional duty, and A G u 359 the distractions of public life, to cultivate his mind. The D’Acmes- Scnptures, which he read and compared in various lan- seau. guages, and the Jurisprudence of his own and other conn- tiies, formed the subjects of his more serious studies i the rest of his time was devoted to philosophy and literature, and the impiovement of his park, where he was sometimes to be seen employed with a spade. From these noble and congenial occupations he was again recalled, by the advice of Cardinal Fleury, in 1727; but the seals were not restored to him till ten years there¬ after. During the intervening period he had endeavoured to mediate in the new disputes which had arisen between the court and the parliament; but his interference seems to have given satisfaction to neither party,—the one re¬ proaching him with desertion from their cause, and the other with too great a leaning towards it. When the seals were at last restored to him, he completely withdrew from all affairs of state, and devoted himself entirely to his duties as chancellor, and to the introduction of those re¬ forms which had long occupied his inquiries and medita¬ tions. Besides some important enactments regarding Dona¬ tions, Testaments, and Successions, he introduced various regulations for improving the forms of procedure, for as¬ certaining the limits of Jurisdictions, and for effecting a greater uniformity in the execution of the laws through¬ out the several provinces. These reforms constitute an epoch in the history of the jurisprudence of France, and have associated his name with those illustrious benefac¬ tors of her Civil Code, L’Hopital and Lamoignon. The duke de Saint-Simon, however, alleges that the chancel¬ lor’s reforms did not go so far as they would have gone had he had less affection for his own order. He once, says this writer, confessed to a nobleman who spoke to him as to the propriety of cutting off certain lucrative abuses, that he could not bring his mind to a step which would so grievously diminish the profits of the law. In 1750, when upwards of eighty-two years of age, he besought the king to accept his resignation; and he was accordingly permitted to retire, the king continuing to him the honours of his office as a special mark of his ap¬ probation. He died in the following year, and was in¬ terred, according to his own request, in the common bu¬ rial-place of the village of Auteuil, where the remains of his wife, who died there in 1735, had been deposited. The name of this lady, whom he married in 1691, and by whom he had several children, was Anne Lefevre d’Or- messon. This great man has not, in all respects, been equally praised by those who have attempted to transmit his cha¬ racter to posterity. Saint-Simon and others reproach him with a degree of tardiness and indecision, which some¬ times greatly obstructed the course of justice. His own answer to this charge has been recorded by Duclos, and is worthy of notice : “ When I recollect,” said he, “ that a decision of the chancellor makes a law, I think myself warranted in taking a long time for consideration.” Saint- Simon and D’Argenson also impute to him some defects as a practical statesman; but his elevation of mind and extensive knowledge, his piety, probity, and disinterest¬ edness, have been universally admitted and extolled. In his magisterial capacity he was grave and dignified, with¬ out any approach to haughtiness; in private society his manners were mild, equal, and even playful. He was par¬ ticularly remarkable for the tenaciousness of his memory, and for the facility with which he could direct his atten¬ tion to the most diversified exercises of the intellectual powers. At eighty years of age he has been heard to repeat whole poems which he had never perused since 360 A G IT AHA "Aguilar u Aguirra. the days of his early youth; and, when fatigued with professional duties, he could turn with equal alacrity to Euclid or to Racine. In summing up his character, all must agree with Laharpe, that he was “ a man who did honour to France, to the magistracy, and to letters, by his virtues, his talents, his profound and various learning, and his enlightened views in the science of jurisprudence.” ( Cours de Litterature, tom. xiv. c. 1.) His published writings form a collection of thirteen volumes quarto, of which the first was published at Paris in 1759, and the last in 1789. The far greater part of these volumes relates to matters connected with his professional occupations and studies; but they also con¬ tain a variety of piecefe upon other subjects. We have already mentioned his Discourses on the studies befitting the students of law, and his treatise on Money. Besides these, and some Theological Pieces, there is a Life of his Father,—interesting from the view which it affords of his own early education under that excellent person; and Metaphysical Meditations, written in vindication of the grand truth, that independently of all revelation, and all positive law, there is that in the constitution of the human mind which renders man a law to himself.

AGUILAR, a town in the arrondissement of Campena, and province of Cordova, in Spain. It is situated on the river Cabra, has 1600 inhabitants, and produces abundance of oil. Aguilar, a town of Spain, in the province of Na¬ varre, about 24 miles west from Estella. Aguilar del Campo, a town of Old Castile, with the title of marquisate, about 15 leagues north of the city of Burgos. AGUILLANEUF, or Augillaneuf, a form of rejoi¬ cing used among the ancient Franks on the first day of the year. The word is compounded of the French A, to, gui, misletoe, and Fan neuf, the new year. Its origin is traced from a druid ceremony: the priests used to go yearly in December, which with them was reputed a sacred month, to gather misletoe of the oak, in great so¬ lemnity. The prophets marched in the front, singing hymns in honour of their deities; after them came a herald with a caduceus in his hand; these were followed by three druids abreast, bearing the things necessary for sacrifice; last of all came the chief or arch druid, accom¬ panied with the train of people. The chief druid, climb¬ ing the oak, cut off the misletoe with a golden sickle, and the other druids received it in a white cloth. On the first day of the year it was distributed among the people, after having blessed and consecrated it by crying A gui Van neuf, to proclaim the new year. AGUILLON, or Aguillonius, Francis, a Jesuit, born at Brussels. He was rector of the Jesuits college at Antwerp, and eminent for his skill in mathematics. He was the first who introduced that science among the Je¬ suits in the Low Countries. He wrote a book of Optics, and was employed in finishing his Catoptrics and Diop¬ trics when he died in 1617. AGUIRRA, Joseph Saenz de, a Benedictine, and one of the most learned men of the 17th century, was born March 24, 1630. He was censor and secretary of the su¬ preme council of the inquisition in Spain, and interpreter of the Scriptures in the university of Salamanca. He print¬ ed three volumes in folio upon Philosophy, a commentary upon Aristotle’s ten books of Ethics, and other pieces. He died at Rome in 1699. AGUR. The xxxth chapter of the Proverbs begins with this title,—“ The wmrds of Agur, the son of Jakeli •” which, according to the signification of the original terms, may be translated, as the Vulgate has it, Verba congrl gantis, filii vomentis ; which translation Le Clerc con¬ demns, supposing these to be proper names which ought not to be translated. These words are rendered by Louis de Dieu, “ the words of him who has recollected himself^ the son of obedience.” The generality of the fathers and commentators will have it that Solomon describes him¬ self under the name of Agur the son of Jakeh ; others con¬ jecture that Agur, as well as Lemuel (in chap. xxxi. 1), were wise men who lived in the time of Solomon, and were his interlocutors in the book of Proverbs; an opinion which F. Calmet thinks is without the least show of pro¬ bability, this book being nothing like a dialogue. This last expositor thinks it probable that Agur was an in¬ spired author different from Solomon, whose sentences it was thought fit to join with those of this prince, because of the conformity of their matter. AGURAH, in Jewish Antiquity, the name of a silver coin, otherwise called gerah and keshita. AGUSADURA, in ancient customs, a fee due from vassals to their lord for the sharpening of their ploughing tackle. Anciently the tenants in some manors were not allowed to have their rural implements sharpened by any but whom the lord appointed, for which an acknowledge¬ ment was to be paid, called agusadura, in some places agusage ; which some take to be the same with what was otherwise called reillage, from the ancient French redh, a ploughshare. AGYEI, in Antiquity, a kind of obelisks, sacred to Apol¬ lo, erected in the vestibules of houses, by way of security. AGYNIANI, in Church History, a sect who condemned all use of flesh, and marriage, as not instituted by God, but introduced at the instigation of the devil. The word is compounded of the privative a, and woman. They are sometimes also called Agynensis, and Agynii; and are said to have appeared about the year 694. It is no won¬ der they were of no long continuance. Their tenets coincide in a great measure with those of the Abelians, Gnostics, Cerdonians, and other preachers of chastity and abstinence. AGYRTfE, in Antiquity, a kind of strolling impostors, running about the country to pick up money, by telling fortunes at rich men’s doors ; pretending to cure diseases by charms, sacrifices, and other religious mysteries; also to expiate the crimes of their deceased ancestors, by vir¬ tue of certain odours and fumigations ; to torment their enemies, by the use of magical verses, and the like. The word is Greek, Ayugra/, formed of the verb ayuou, I con¬ gregate ; alluding to the practice of charlatans or quacks, who gather a crowd about them. Agyrtce, among the Greeks, amount to the same with AEruscatores among the Latins, and differ not much from gypsies among us. AHAB, son of Omri, king of Israel, succeeded his father a. m. 3086, and surpassed all his predecessors in impiety and wickedness. He married Jezebel, the daugh¬ ter of Ethbaal, king of the Zidonians, who introduced the idols of Baal and Astarte among the Israelites, and en¬ gaged Ahab in the worship of these false deities. God, being provoked by the sins of Ahab, sent the prophet Elijah to him (1 Kings xvii. 1, seq.), who declared to him that there would be a famine of three years’ continuance. The dearth having lasted three years, the prophet desires Ahab to gather all the people to Mount Carmel, and with them the prophets of Baal: when they were thus as¬ sembled, Elijah caused fire to descend from heaven upon his sacrifice; after which he obtained of God that it shouk A H A AHA 361 V i. rain, and then the earth recovered its former fertility. r six years after this, Ben-hadad, king of Syria (chap, xx.), laid siege to Jerusalem. But God, provoked at this proud Syrian, sent a prophet to Ahab, not only to assure him of victory, but to instruct him likewise in what manner he was to obtain it. Ahab was ordered to review the princes of the provinces, which he found to be a choice company, consisting of 232 young men, who were to command the people in Samaria, amounting to about 7000 men. With this small army Ahab was directed to fall upon the great host of the Syrians, and that at noon-day, while Ben-hadad and the 32 kings that accompanied him were drinking and making merry. Ben-hadad having notice that they were marching out of the city, ordered them to be brought before him alive, whatever their designs were; but the oung men, followed by this small army, advanced, and illed all that opposed them. Such a panic seized the Syrian troops, that they began to fly, and even Ben-hadad himself mounted his horse and fled with his cavalry; which Ahab perceiving, pursued them, killed great num¬ bers of them, and took a considerable booty. After this the prophet came to Ahab, to animate him with fresh courage, and to caution him to keep upon his guard, as¬ suring him that Ben-hadad would return against him the year following. According to this prediction, at the end of the year he returned and encamped at Aphek, with a resolution to give the Israelites battle. Both armies being ranged in order of battle for seven days successively, at length, upon the seventh day, a battle ensued, wherein the Israelites killed 100,000 of the Syrians, and the rest fled to Aphek; but as they were pressing to get into the city, the walls of Aphek fell upon them, and killed 27,000 more. Ben-hadad throwing himself upon the mercy of Ahab, this prince received him into his own chariot, and made an alliance with him. The year following, Ahab desiring to make a kitchen-garden near his palace (chap xxi.), re¬ quested of one Naboth, a citizen of Jezreel, that he would sell him his vineyard, because it lay conveniently for him. But being refused, he returned in great discontentment to his house, threw himself upon the bed, turned towards the wall, and would eat nothing. Jezebel his wife coming in, asked the reason of his great concern, of which being informed, she procured the death of Naboth, and Ahab took possession of his vineyard. As he returned from Jezreel to Samaria, the prophet Elijah met him, and said, “ Hast thou killed, and also taken possession ? Thus saith the Lord, In the place where dogs licked the blood of Naboth, shall dogs lick thy blood, even thine. As for Jezebel, of her the Lord spoke, saying, The dogs shall eat Jezebel by the way of Jezreel.” Ahab, hearing these and other denunciations, rent his clothes, put sackcloth upon his flesh, and gave other indications of his sorrow and repentance. But his repentance was neither sincere nor persevering. Two years after these things, Jehosha- phat, king of Judah, came to Samaria to visit Ahab (chap, xxn.), at a time when he was preparing to attack Ramoth- gnead, which Ben-hadad, king of Syria, unjustly withheld iom him. The king of Israel invited Jehoshaphat to ac¬ company him in this expedition, which that prince agreed to do, but desired that some prophet might first be consult¬ ed. Ahab therefore assembled the prophets of Baal, in number about 400, who all concurred in exhorting the ^*ng to march resolutely against Ramoth-gilead. But | icaiah, being also consulted at Jehoshaphat’s sugges- °n, pi ophesied the ruin of Ahab. Upon this Ahab gave or ers to his people to seize Micaiah, and to carry him o Amon the governor of the city, and to Joash the 'mgs son, telling him in his name, “ Put this fellow in 16 prison, and feed him with bread of affliction and VOL. II. with water of affliction, until I come in peace.” But Micaiah said, “ If thou return at all in peace, the Lord hath not spoken by me.” Ahab, therefore, and Jehoshaphat, marched up to Ramoth-gilead; and the king of Israel said unto Jehoshaphat, “ I will disguise myself and enter into the battle; but put thou on thy robes:” for he knew that the king of Syria had com¬ manded two-and-thirty captains that had" rule over his chariots, saying, « Fight neither with small nor with great, save only with the king of Israel.” These officers, therefore, having observed that Jehoshaphat was dressed in royal robes, took him for the king of Israel, and fell upon him with great impetuosity : but this prince seeing himself pressed so closely, cried out; and the mistake being discovered, the captains of the king of Syria gave over pursuing him. But one of the Syrian army shot a ran¬ dom arrow, which pierced the heart of Ahab. The battle lasted the whole day, and Ahab continued in his chariot with his face turned towards the Syrians. In the mean time his blood was still issuing from his wound and fall¬ ing into his chariot, and towards the evening he died; whereupon proclamation was made, by the sound of trum¬ pet, that every man should return to his own city and country. The king of Israel being dead, was carried to Samaria and buried ; but his chariot and the reins of his horses were washed in the fish-pool of Samaria, and the dogs licked his blood, according to the word of the pro¬ phet. Such was the end of Ahab. His son Ahaziah suc¬ ceeded him in the year of the world 3107. AHASUERUS, or Artaxerxes, the husband of Esther, and, according to Archbishop Usher and F. Calmet, the Scripture name for Darius, the son of Hystaspes, king of Persia; though Scaliger supposed Xerxes to have been the husband of Esther, or the Ahasuerus of Scripture: and Dr Prideaux believes him to be Artaxerxes Longi- manus. See History of Persia. AHAUS, a circle in the department of Munster, and Prussian province of Westphalia, formed out of the old lordships of Bocholt and Horstmar. It is 301 square miles, or 192,640 acres, in extent, comprehending three cities, six market towns, and 58 parishes, with 33,470 inhabitants. The soil is moderately fertile, and yields mo¬ derate crops of corn, buck-wheat, and flax. It is watered by the Aa, the Berkel, the Bechta, the Dinkel, and several smaller streams. The most valuable products are cattle, and especially sheep. There is some little spinning and weaving of linen; but the higher wages paid in Holland induce the labourers to go to that country, in the seasons of hay and corn harvest, to save the means of subsistence for the winter.—The chief city of the circle, of the same name, is the residence of the count, now mediatized; and contains, besides his castle, 300 houses, and 1103 inha¬ bitants. Long. 7. 4. 34. E. Lat. 52. 4. 38. N. AHAZ, king of Judah, the son of Jotham, remarkable for his vices and impieties. One of his sons he conse¬ crated, by making him pass through and perish by the fire, in honour of the false god Moloch; and he offered sacrifices and incense upon the high places, upon hills, and in groves. Rezin, king of Syria, and Pekah, king of Israel, invaded Judah in the beginning of the reign of Ahaz; and having defeated his army and pillaged the country, they laid siege to Jerusalem. When they found that they could not make themselves masters of that city, they divided their army, plundered the country, and made the inhabitants prisoners of war. Rezin and his part of the confederate army marched with all their spoil to Damascus; but Pekah, with his division of the army, having attacked Ahaz, killed 120,000 men of his army in one battle, and carried away men, women, and children, 2 z Ahab 362 A H I A H I Ahaziah without distinction, to the number of 200,000. But as Jj they were carrying those captives to Samaria, the prophet Ahij ah. Qded, with the principal inhabitants of the city, came out to meet them, and by their remonstrances prevailed with them to set their prisoners at liberty. At the same time the Philistines and Edomites invaded other parts of his land, killed multitudes of the people, and carried off much booty. In this distressed condition, Ahaz, finding no other remedy for his affairs, sent ambassadors to Tiglath-pileser, king of the Assyrians ; and to engage him to his interest, he stripped the temple and city of all the gold which he could meet with, and sent it as a present. Accordingly Tiglath-pileser marched to the assistance of Ahaz, attacked Rezin, and killed him, took his capital Damascus, de¬ stroyed it, and removed the inhabitants thereof to Gyrene. The misfortunes of this prince had no influence to make him better ; on the contrary, in the times of his greatest affliction, he sacrificed to the Syrian deities, whom he looked upon as the authors of his calamities, and endea¬ voured to render propitious to him, by honouring them in this manner. Pie broke in pieces the vessels of the house of God, shut up the gates of the temple, and erected al¬ tars in all parts of Jerusalem. He set up altars likewise in all the cities of Judah, with a design to offer incense on them. At length he died, and was buried in Jerusa¬ lem, but not in the sepulchres of the kings of Judah his predecessors; which honour he was deprived of on ac¬ count of his iniquitous course of life. Hezekiah his son succeeded him in the year of the world 3287, before Jesus Christ 726. AHAZIAH, the son and successor of Ahab, king of Israel, reigned two years, part alone, and part with his father Ahab, who ordained him associate in the kingdom a year before his death. Ahaziah imitated his father’s impieties (1 Kings xxii. 52, seq.), and paid his adoration to Baal and Astarte, the worship of whom had been in¬ troduced into Israel by Jezebel, his mother. The Moabites, who had been always obedient to the kings of the ten tribes ever since their separation from the kingdom of Judah, revolted after the death of Ahab, and refused to pay the ordinary tribute. Ahaziah had not leisure or power to reduce them (2 Kings i. 1, 2, &c.); for about the same time, having fallen through a lattice from the top of his house, he hurt himself considerably, and sent messengers to Ekron, in order to consult Baalzebub, the god of that place, whether he should recover of the in¬ disposition occasioned by this accident. But the prophet Elijah went to Ahaziah, and declared that he should not recover from his illness; and accordingly he died in the year of the world 3108, and Jehoram his brother succeed¬ ed to the crown. Ahaziah, king of Judah, the son of Jehoram and Atha- liah, succeeded his father in the kingdom of Judah, in the year of the world 3119. He walked in the ways of Ahab’s house, to which he was allied. He reigned only one year. He was slain by Jehu the son of Nimshi. AHEAD, a sea-term, signifying farther onward than the ship, or at any distance before her, lying immediately on that point of the compass to which her stem is direct¬ ed. It is used in opposition to astern, which expresses the situation of any object behind the ship. AHIJAH, the prophet of Shiloh. He is thought to be the person who spoke twice to Solomon from God; once while he was building the temple (1 Kings vi. 11), at which time he promised him his protection; and at an¬ other time (id. xi. 6) after his falling into all his irregu¬ larities, when God expressed his indignation with great threatenings and reproaches. Ahyah was one of those who wrote the annals or history of this prince (2Chr.ix.29). The same prophet declared to Jeroboam that he would A! usurp the kingdom (1 Kings xi. 29, &c.), and that two heifers should alienate him from the Lord, meaning theAllit ^ golden calves erected by Jeroboam, one at Dan, the^ other at Bethel. About the end of Jeroboam’s reign, to¬ wards the year of the world 3046, Abijah, the son of that prince, fell sick; upon which Jeroboam sent his wife to this prophet to inquire what would become of the child. The queen therefore went to Ahijah’s house in Shiloh, disguised; but the prophet, upon hearing the sound of her feet, said, “ Come in, thou wife of Jeroboam, why feignest thou thyself to be another ? for I am sent to thee with heavy tidings.” Then he commanded her to go and tell Jeroboam all the evil that the Lord had declared he would bring upon his house for his impieties; that so soon as she should enter into the city her son Abijah should die, and should be the only one of Jeroboam’s house that should come to the grave or receive the honours of a burial. Ahijah in all probability did. not long survive the time of this last prophecy; but with the time and manner of his death we are not acquainted. AHJOLI, a city on the bay of Borgas, in the Black Sea, surrounded with many wund-mills, and of commercial consequence from the copious springs, from which salt is made. It is in the Turkish province of Silistria, a part of ancient Bulgaria. AHITHOPHEL, a native of Gillo,wasfor some time the counsellor of King David, whom he at length deserted by joining in the rebellion of Absalom. This prince, upon his being preferred to the crown by the greater part of the Israelites, sent for Ahithophel from Gillo (2 Sam. xv. 12) to assist him with his advice in the present state of his affairs ; for at that time Ahithophel’s counsels were received as the oracles of God himself (chap. xvi. idt(). Nothing gave David more uneasiness than this event; and when Hushai his friend came to wait on him and attend him in his flight, he entreated him to return rather to Jerusalem, make a show of offering his services to Absalom, and en¬ deavour to frustrate the prudent measures which should be proposed by Ahithophel. When Absalom was come to Jeru¬ salem, he desired Ahithophel to deliberate with his other counsellors upon the measures which wrere proper for him to take. Ahithophel advised him, in the first place, to abuse his father’s concubines; so that when his party should understand that he had dishonoured his father in this manner, they might conclude that there were no hopes of a reconciliation, and therefore espouse his interest more resolutely. A tent, therefore, being prepared for this pur¬ pose upon the terrace of the king’s palace, Absalom, in the sight of all Israel, lay with his father’s concubines. The next thing Ahithophel proposed was in the terms fol¬ lowing : “ Let me now choose out 12,000 men, and I will arise and pursue after David this night; and I will come upon him while he is weary and weak-handed, and will make him afraid; and all the people that are with him shall flee, and I will smite the king only; and I will bring back all the people unto thee : the man whom thou seekest is as if all returned; so all the people shall be in peace.” This advice was very agreeable to Absalom and all the elders of Israel. However, Absalom desired Hushai to be call¬ ed to have his opinion. Hushai being come, and hearing what advice Ahithophel had given, said, “ The counsel which Ahithophel has given is not good at this time; what, for the present, in my opinion, may do better, is this: “ Let all Israel be gathered unto thee, from Dan even to Beer- sheba, as the sand that is by the sea for multitude, and put thyself in the midst of them; and wherever David is, we will fall upon him, and overwhelm him with our num¬ bers, as the dew falleth upon the ground.” The last ad- A I Ai, ; Ji vice, being more agreeable to Absalom and all the elders i 0f Israel, was preferred; upon which Ahithophel saddled jl his ass, went to his house at Gillo, hanged himself, and ^"^was buried in the sepulchre of his fathers. He foresaw, without doubt, all that would happen in consequence of Husbai’s advice, and was determined to prevent the death which he had deserved, and which David would probably have inflicted on him as soon as he should be resettled on his throne. AHOLIBAH and Aholah are two feigned names made use of by Ezekiel (xxiii. 4) to denote the two king¬ doms of Judah and Samaria. Aholah and Aholibah are represented as two sisters of Egyptian extraction. Aholah stands for Samaria, and Aholibah for Jerusalem. The first signifies a tent; and the second, my tent is in her. They both prostituted themselves to the Egyptians and Assy¬ rians, in imitating their abominations and idolatries; for which reason they were abandoned to those very people for whom they had shown so passionate and so impure an affection. They were carried into captivity, and reduced to the severest servitude. AHRWEIL, a circle in the department of Coblentz, and the Prussian province of the Lower Rhine. It extends over 96 square miles, or 61,440 acres ; contains 24,745 inhabitants, all Catholics except 400 Protestants, in three cities, two market towns, and 186 villages. The Rhine washes its eastern border, and receives the water of the Ahr, which issues out of a fertile valley, near Sinzig, whence some good wine from the sides of the hills is pro¬ duced. The rest of the district is poor in agriculture, and only somewhat better in breeding cattle, and furnish¬ ing fish, game, wood, and stone. The capital is a small city of the same name. It is built on the banks of the Ahr, containing 400 houses, and 2079 inhabitants, chiefly tanners, curriers, and makers of wine. AHULL, in the sea language, the situation of a ship when all her sails are furled on account of the violence of the storm, and when, having lashed her helm on the lee- side, she lies nearly with her side to the wind and sea, her head being somewhat inclined to the direction of the wind. AHUN, a town of France, in the Upper Marche and generality of Moulins, in the department of Creuse.

Long. 14. 10. E. Lat. 56. 20. N. AI, in Ancient Geography, a town in Judea, to the north of Jericho, called A/wz by Josephus, and the inhabitants AinattB. Joshua having sent a detachment of 3000 men against Ai, God permitted them to be repulsed on account of Achan’s sin, who had violated the anathema pronoun¬ ced against the city of Jericho. But after the expiation of this offence, God commanded Joshua (chap, viii.) to march with the whole army of the Israelites against Ai, and treat this city and the kingdom thereof as he had treated Jeri¬ cho, with this difference, that he gave the plunder of the town to the people. Joshua sent by night 30,000 men to lie in ambush behind Ai, having first well instructed those who had the command of them in what they were to do; and the next day, early in the morning, he marched against the city with the remainder of his army. The king of Ai perceiving them, sallied hastily out of the town with all his people, and fell upon the forces of the Israelites, who, upon the first onset, fled, as if they had been under some great terror. A j A 363 As soon as Joshua saw the enemy all out of the gates, Ajaccio lie raised his shield upon the top of a pike, which was the II signal given to the ambuscade; whereupon they immedi- Aichstadt. ately entered the place, which they found without de- fence, and set fire to it. The people of Ai perceiving the. smoke ascending, were willing to return, but discovered those who had set fire to the city in their rear; while Joshua and those who were with him turning about, fell upon them, and cut them in pieces. The king was taken alive, and afterwards put to death. AJACCIO, or Aj azzo, an arrondissement in the island and department of Corsica, in the Mediterranean, con¬ taining 12 cantons and 72 communes, with 36,980 inha¬ bitants. The extent is 736 square miles, or 460,000 Eng¬ lish acres. The capital, which bears the same name, and is the best built town in the island, is situated in a fer¬ tile territory, which produces excellent wines. It has a small citadel and an excellent harbour, and contains 6840 inhabitants. It is celebrated as the birth-place of Napoleon Buonaparte. AJALON, in Ancient Geography, a town of the tribe of Dan, one of the Levitical. Another in the tribe of Benjamin, in whose valley Joshua commanded the moon to stand still, being then in her decrease, and consequent¬ ly to be seen at the same time with the sun. A JAN, a coast and country of Africa, has the river Quilimanci on the south; the mountains from which the river springs, on the west; Abyssinia or Ethiopia, and the strait of Babelmandel, on the north; and the Eastern or Indian Ocean on the east. The coast abounds with all the necessaries of life, and has plenty of very good horses. The whole sea-coast, from Zanguebar to the strait of Ba- belmandel, is called the coast of Ajan; and a considerable part of it is styled the Desert coast. AJAX, the son of Oileus, was one of the principal gene¬ rals who went to the siege of Troy. He ravished Cas¬ sandra, the daughter of Priam, even in the temple of Mi¬ nerva, where she thought to have found sanctuary. It is said he made a serpent of 15 feet long so familiar with him, that it ate at his table, and followed him like a dog. The Locrians had a singular veneration for his memory. Ajax, the son of Telamon, was, next to Achilles, the most valiant general among the Greeks at the siege of Troy. He commanded the troops of Salamis, and per¬ formed many great actions, of which we have an account in the Iliad, in Dictys Cretensis, and in the 23d book of Ovid’s Metamorphoses. He was so enraged that the arms of Achilles were adjudged to Ulysses, that he immediate¬ ly became mad. The Greeks paid great honour to him after his death, and erected a magnificent monument to his memory, upon the promontory of Rhetium. Ajax, in Antiquity, a furious kind of dance, in use among the Grecians ; intended to represent the madness of that hero after his defeat by Ulysses, to whom the Greeks had given the preference in his contest for Achil¬ les’s arms. Lucian, in his treatise of Dancing, speaks of dancing the Ajax.—There was also an annual feast called Ajantia, A/am/a, consecrated to that prince, and observed with great solemnity in the island of Salamis, as well as in Attica; where, in memory of the valour of Ajax, a bier was exposed, set out with a complete set of armour. Ajazzo, a seaport town of Natolia, in the province of Caramania, anciently Cilicia, seated on the coast of the Mediterranean, 30 miles north of Antioch, and 50 west of Aleppo, where the city of Issus anciently stood, and near which Alexander fought his second battle with Darius.

AIGHENDALE, the name of a liquid measure used in Lancashire, containing seven quarts. AIGLE, a bailiwick in the territory of Romand in Switzerland, consists of mountains and valleys, the princi¬ pal of which are the Aigle and Bex. Through these is the great road from Valais into Italy. When you pass by Villeneuve, which is at the head of the lake of Geneva, you enter into a deep valley three miles wide, bordered on one side with the Alps of Switzerland, on the other side with those of Savoy, and crossed by the river Rhone. Six miles from thence you meet with Aigle, a town con¬ taining 2500 inhabitants, seated in a wide part of the val¬ ley, where there are vineyards, fields, and meadows. The governor's castle is on an eminence that overlooks the town, and has a lofty marble tower. This government has nine large parishes; and is divided into four parts, Aigle, Bex, Olon, and Ormont. This last is among the moun¬ tains, and joins to Rougemont. It is a double valley, abounding in pasture lands. Ivorna, in the district of Aigle, was in part buried by the fall of a mountain, occa¬ sioned by an earthquake, in 1584. Aigle, a city in France, in the arrondissement of Mor- tagne, and department of the Orne.

AIKMAN, William, a painter of considerable emi¬ nence, was born in Scotland, October 24. 1682. He was the son of William Aikman, Esq. of Cairney, and was in¬ tended by his father to follow his own profession, which was that of an advocate at the Scotish bar. But the genius of the son led him to other studies. He devoted himself to the fine arts, especially that of painting; and having for some time prosecuted his studies in Britain, in the year 1707 he went to Italy, resided in Rome for three years, afterwards travelled to Constantinople and Smyrna, and in 1712 returned to his own country. About the year 1723 he fixed his residence in London, where he fol¬ lowed the profession of painting, and had the good for¬ tune to be patronised by the duke of Argyle, the earl of Burlington, Sir Godfrey Kneller, and other liberal en- couragers of the arts. He painted many portraits of per¬ sons of the first rank in England and Scotland, and a large picture of the royal family for the earl of Burling¬ ton, now in the possession of the duke of Devonshire, which was unfinished at his death. Some of his portraits painted in Scotland are in the possession of the duke of Argyle, the duke of Hamilton, and others. Mr Aikman died in London, June 4. 1731. Six months previous to his death he had lost a son at the age of 17. The remains of both were removed to Edinburgh, and were interred in the Greyfriars church-yard on the same day. Mr Somer¬ ville, the author of the Chace, Mr Mallet, Mr Allan Ram¬ say the Scotish poet, and Mr Thomson, were among Mr Aikman’s intimate acquaintance; and the muse of each, in elegiac numbers, offered a warm tribute to the memory of their departed friend. The following epitaph, from the pen of Mr Mallet, was engraved on his tomb: Dear to the good and wise, disprais’d by none, Here sleep in peace the father and the son ; By virtue, as by nature, close ally’d, The painter’s genius, but without the pride ; Worth unambitious, wit afraid to shine, Honour’s clear light, and friendship’s warmth divine. The son, fair rising, knew too short a date ; But, oh ! how more severe the father’s fate! He saw him torn untimely from his side, Felt all a father’s anguish—wept, and died. Mr Aikman’s style of painting was an imitation of the pleasing simplicity of nature. It is distinguished by soft¬ ness of light, mellowness of shade, and mildness and har¬ mony of colouring. His compositions have more placid tranquillity of ease than boldness of touch and brilliancy of effect. His portraits are supposed to have some resem¬ blance to those of Kneller, not only in the imitation of the dresses of the time, but in the similarity of tint and manner of working.

AILMER, or /Ethelmare, earl of Cornwall and De¬ vonshire in the reign of King Edgar. It is not known of what family he was. His authority and riches were great, and so also in appearance was his piety. He founded the abbey of Cernel, in Dorsetshire; and had so great a vene¬ ration for Eadwald, the brother of St Edmund the Martyr, who had lived a hermit in that country, near the Silver Well, as it is called, that, with the assistance of Arch¬ bishop Dunstan, he translated his relics to the old church of Cernel. In 1016, when Canute, the son of Sueno, in¬ vaded England, and found himself stoutly opposed by that valiant Saxon prince Edmund Ironside, the son of Athelred, this Earl Ailmer, with that arch-traitor Eadric Streone, earl of Mercia, and Earl Algar, joined the Dane against their natural prince, which was one great cause of the Saxons’ ruin. He did not long survive this ; and we find mentioned in history only one son of his, whose name was Asthelward, earl of Cornwall, who followed his father’s maxims, and was properly rewarded for it; for in 1018, Canute, reaping the benefit of their treasons, and perceiv¬ ing that the traitors were no longer useful, caused the infamous Eadric Streone and this Earl iEthelward to be both put to death. AILRED, or Ealred, abbot of Revesby, in Lincoln¬ shire, in the reigns of Stephen and Henry II. He was born in 1109, of a noble family, and educated in Scotland with Henry, the son of King David. On his return to Eng¬ land he became a monk of the Cistercian order in the monastery of Revesby, of which he afterwards was made abbot. He died on the 12th of January 1166, aged 57, and was buried in hi§ monastery. “ He was,” says Leland, “ in great esteem during his life, celebrated for the mi¬ racles wrought after his death; and admitted into the catalogue of saints.” He was author of several works, most of which were published by Gilbo the Jesuit at Douay, 1631: part of them may be also found in the Bib- Iwtheca Cisterciensis, and Bibliotheca Patrum. His prin¬ cipal work is the Speculum Charitatis. Leland, Bale, and fits, mention several manuscripts which never were pub¬ lished. AILSA, an insulated rock on the western coast of Scot¬ land, between the shores of Ayrshire and Cantyre. It is two miles in circumference at the base, is accessible only at one place, and rises in a pyramidical form to the height of 940 feet. A few goats and rabbits pick up a subsistence among the grass and furze; but it is frequented by immense numbers of soland geese and other birds, which are valued for their flesh or feathers. The depth of water around me base is from 7 to 48 fathoms. On one part of the rock are the remains of an old castle, which is said to have been erected by Philip II. of Spain, about the time that die Spanish armada invaded Britain. AJMEER, or Rajpootana, a large province situated in the centre of Hindostan, between the 24th and 31st degrees of N. lat. It is bounded on the north by the pro¬ vinces of Moultan, Lahore, and Delhi; on the south by Lujerat and Malwah ; on the east by Delhi and Agra, and on the west by Moultan and the principality of Sinde. rom north to south it extends 350 miles, and is 200 in average breadth. The following are the modern divisions of this province:— 1. The Bhatty country. 3. The Great Sandy Desert. Bicanere. 4. Jesselmere. 5. Joudpoor. 10. Ajmeer district 6. Marwar. 11. Harowty. 7. Nagore. 12. Odeypoor. 8. Shekawutty. 13. Mewar. 9. Jeypoor. 14. Sarowy. This province is generally of a barren and sandy soil, in. many parts a good deal covered by thorny trees and thickets of the cactus. The province of Marwar has a superior soil, and is in a better state of cultivation than the eastern provinces of Jeypoor and Ajmeer, or the south¬ western tract of Mewar, including Odeypoor. This part of the country was laid waste to such a degree by the ravages of the Pindarees, that it has yet scarcely recovered. The soil, naturally arid, is in some of the southern pro¬ vinces rendered productive by streams which descend from the mountains. The Chumbul, Calysina, and Banass are the most considerable streams; and where they afford supplies of moisture, the country presents something like the appearance of verdure. The soil of the whole pro¬ vince is remarkably saline, containing many salt springs and lakes, and producing salt and saltpetre spontaneously. In other parts, in order to procure a supply of water, deep wells are sunk, from which the country being partially irrigated, yields wheat, barley, and other sorts of grain and pulse common in India. In Marwar, where they derive their supplies of water from these deep wells, Bishop Heber mentions that he saw cotton growing of the finest quality, and oxen and sheep which bore evidence, by their size and fatness, of the luxuriance of the pasture. Other parts, again, of the southern provinces are strangely desolate, though the ruins with which they are covered, and the numerous tombs, show that they have been inhabited at no distant period, and that their present desolation has been the work of violence. Towards the east, and in the north, there is an exten¬ sive tract, which is a continued desert of the most dismal appearance. Towards the south mountainous tracts occur, and between Marwar and Mewar they rise to 2000 feet above the level of the sea. The mountains of Aboo, towards the western boundary, rise, it is supposed, to the height of 6000 feet. Except in the mountains, trees are seldom seen; and the consequence is, that timber for building and other purposes is extremely scarce, and pro- portionably dear. Such is the scarcity of wooden furni¬ ture, that at dinner parties it is the practice among the British residents for ladies and gentlemen to send their own chairs to the house where the entertainment is to take place; and they have nothing better for their doors and windows than pieces of matting. The Shekawultz country on the west is sandy, badly watered and culti¬ vated, scattered over with rocky hills, and sprinkled with tufts of long grass and bushes. Yet it contains several lai’ge towns; and it seems to lose its title to be included in the desert, when compared with the tract which extends north-east as far as Bahawulpoor, a distance of 280 miles; and even this tract is only for the last hundred miles ab¬ solutely destitute of inhabitants, water, or vegetation. For 180 miles the country presents the appearance of hills and valleys of loose and heavy sand from 20 to 100 feet in height. These hills shift their positions; and the passage of the desert is rendered dangerous in summer by clouds of moving sand. Among these sandy deserts villages are occasionally met with, which consist merely of a few round huts of straw, with low conical roofs like stooks of corn. They are surrounded by hedges of dry thorny branches, stuck in the sand. Around these miser¬ able abodes are to be seen a few fields, which depend for water on the rains and dews, and which bear thin crops of the poorest kinds of pulse, and a species of the holcus spi- Ajmeer. 366 A J M A J M Ajmeer. catuSy which, though it flourishes in the most sterile countries, grows here with difficulty, each stalk several feet from its neighbour.

At these meetings, which, as they were not select, must be supposed to have consisted of such persons as usually meet for the purpose of gossiping, men of wealth, but of ordinary endowments, and able to talk of little else than news and the occurrences of the day, Akenside was for displaying those talents which had acquired him the reputation he enjoyed in other companies; but here they were of little use to him; on the contrary, they tended to engage him in disputes that betrayed him into a contempt of those who differed in opinion from him. It was found out that he was a man of low birth, and a dependent on Mr Dyson; circumstances that furnished those whom he offend¬ ed with a ground of reproach, which reduced him to the necessity of asserting in terms that he was a gentleman. Little could be done at Hampstead after matters had proceeded to this extremity. Mr Dyson parted with his villa at North-End, and settled his friend in a small house in Bloomsbury-square, assigning for his support such a part of his income as enabled him to keep a chariot. In this new situation Akenside used every endeavour to be¬ come popular, but defeated them all by the high opinion he everywhere manifested of himself, and the little con¬ descension he showed to men of inferior endowments ; by his love of political controversy, his authoritative censure of the public councils, and his peculiar notions respecting government. In the winter evenings he frequented Tom’s coffee-house in Devereux-court, then the resort of some of the most eminent men for learning and ingenuity of the time, with some of whom he was involved in disputes and altercations, chiefly on subjects of literature and politics, which fixed on his character the stamp of haughtiness and self-conceit. Hence many, who admired him for his genius and parts, were shy of his acquaintance. , The value of that precept which exhorts us to live peaceably with all men, or, in other words, to avoid creat¬ ing enemies, can only be estimated by the reflection on those many amiable qualities against which the neglect of it will preponderate. Akenside was a man of religion and strict virtue; a philosopher, a scholar, and a fine poet. His conversation was of the most delightful kind; learned, instructive, and, without any affectation of wit, cheerful and entertaining. Dr Akenside died of a putrid fever, June 23.1770; and is buried in the parish-church of St James’s, Westminster. His poems, published soon after his death in 4to and 8vo, consist of the Pleasures of Imagination, two books of Odes, a Hymn to the Naiads, and some Inscriptions. The Pleasures oflmagination, his capital work, was first pub¬ lished in 1744; and a very extraordinary production it was, from a man who had not reached his 23d year. He was afterwards sensible, however, that it wanted revision and correction ; and he went on revising and correcting it for several years; but finding this task to grow upon his hands, and despairing of ever executing it to his own satis¬ faction, he abandoned the purpose of correcting, and re¬ solved to write the poem over anew upon a somewhat dif¬ ferent and enlarged plan. He finished two books of his new poem, a few copies of which were printed for the use of the author and certain friends; of the first book in 1 /, of the second in 1765. He finished also a good part of a third book, and an introduction to a fourth; but his most munificent and excellent friend, conceiving all that is exe¬ cuted of the new work too inconsiderable to supply the place and supersede the republication of the original poem, and yet too valuable to be withheld from the public, has caused them both to be inserted in the collection of his poems. rtnai issai AKERMAN, a circle in the Russian province of Bess- l arabia, extending along the banks of the Black Sea, where the Dneish forms an estuary. It is nearly destitute of population, except the capital, of the same name, which ^ is built on a tongue of land projecting into the estu¬ ary. It is the ancient Roman colony of Alba Julia. It is surrounded with strong walls and ditches, contains a Greek and a beautiful Arminian church, several-mosques, and a synagogue for Jews. The population, of various na¬ tions, religions, and languages, amounts to about 15,000. It is a place, from its position, of considerable trade. It is in long. 30. 10. 15. E. and lat. 46. 11. 45. N. AKHMETSCHET, or Simferopol,one ofthe six circles into which the Russian government or province of Taurien is divided. It is the richest and most fruitful part ofthe peninsula, extending from long. 32. 31. to 33. 46. E. and from lat. 44. 30. to 45. 9. N. About two-thirds of the dis¬ trict is hilly, and gives rise to the rivers Katscha, Belbak, and Alma, as well as many smaller streams, by whose water fertility is dispersed in the valleys and plains. The circle is estimated to contain about 50,000 inhabitants. Akhmetschet, a city, the capital of the circle of the same name, in the province of Taurien. It is composed of two parts; the old town, a mere heap of Tartar booths ;and the new, built on a regular plan, since the extinction of the former government, with a few good public edifices. It contains three mosques, a Russian, Arminian, and Greek church, with 900 houses, and, according to Usewoloske, 20,000 inhabitants, of various nations and religions. A re giment of Russians is constantly in garrison in the city, It is in long. 34.1. which is only moderately fortified, and lat. 44. 59. N. AKHTIAR, or Sevastopol, a city in the Russian go¬ vernment of Taurien, in the circle Akhmetschet. It lies in a bay, the best harbour of the Taurida, where the Russians have formed an arsenal for the construction and equipment of a navy. The bay is sufficiently extensive to admit of a large fleet, and the depth of water is from 10 to 12 fathoms. There are neither shoals, rocks, nor sand-banks, and vessels are secure from all winds. The inhabitants, exclusive of the garrison, amount to 1500. It is considered rather an unhealthful situation, and the water is not good. It is in long. 33. 27. 40. E. and lat. 44. 41. 30. N. AKIBA, a famous rabbin, flourished a little after the destruction of Jerusalem by Titus. He kept the flocks of a rich citizen of Jerusalem till the 40th year of his age, and then devoted himself to study in the academies for twenty-four years; and was afterwards one of the greatest masters in Israel. According to the Jewush accounts, he had 24,000 scholars. He declared for the impostor Bar- cochebas, whom he owned for the Messiah; and not only anointed him king, but took upon himself the office of Ins master of the horse. The troops which the emperor Had¬ rian sent against the Jews, who under the conduct of this false Messiah had committed horrid massacres, extermi¬ nated this faction, ^ikiba was taken, and put to death with great cruelty. He lived 120 years, and was buried with his wife in a cave upon a mountain not far from Tiberias, an his 24,000 scholars were buried round about him upon the same mountain. It is imagined he invented a suppositi¬ tious work under the name of the patriarch Abraham. AKISSAR, the ancient Thyatira, a city of Natolia, m Asia, situated in a plain 18 miles broad, which produces plenty of cotton and grain. The inhabitants, who are rec¬ koned to be about 5000, are said to be all Mahometans. The houses are built of nothing but earth or turf dried m the sun, and are very low and ill contrived; but there are six or seven mosques, which are all of marble. There are remarkable inscriptions on marble in several parts of tie ALA town, which are part of the ruins of the ancient Thyatira. A i] It is seated on the river Hermus, 50 miles from Pergamos. AlabiA Long. 28. 30. E. Lat. 38. 50. N. AKOND, an officer of justice in Persia, who takes cog¬ nizance of the causes of orphans and widows, of contracts, and other civil concerns. He is the head of the school of law, and gives lectures to all the subaltern officers. He has his deputies in all the courts of the kingdom, who, with the second sadra, make all contracts. AL, an Arabic particle prefixed to words, and signify¬ ing much the same with the English particle the. Thus they say, alkermes, alkoran, &c. i. e. the kermes, the koran, &c. Ax, or Ald, a Saxon term, frequently prefixed to the names of places, denoting their antiquity ; as, Aldborough, Aldgate, &c. ALA, a Latin term, properly signifying a wing; from a resemblance to which several other things are called by the same name. Thus, Ala is a term used by botanists for the hollow of a stalk, which either the leaf or the pedicle of the leaf makes with it; or it is that hollow turning, or sinus, placed between the stalk or branch of a plant and the leaf, whence a new offspring usually issues. Sometimes it is used for those parts of leaves otherwise called lobes or wings. ALiE, the plural number, is used to signify those petals or leaves of papilionaceous flowers placed between those others which are called the vexillum and carina, and which make the top and bottom of the flowers. Instances of flowers of this structure are seen in those of peas and beans, in which the top leaf or petal is the vexillum, the bottom the carina, and the side ones the alae. Ala; is also used for those extremely slender and mem¬ branaceous parts of some seeds which appear as wings placed on them. It likewise signifies those membranaceous expansions running along the stems of some plants, which are therefore called alated stalks. Ala, in Anatomy, a term applied to the lobes of the liver, the cartilages of the nostrils, &c. Ala, in the Roman Art of War, were the two wings or extreme parts of the army drawn up in order of battle. At A BA, one of the three smallest districts of Biscay, in Spain, but pretty fertile in rye, barley, and fruits. There are in it very good mines of iron, and it had for¬ merly the title of a kingdom. ALABAMA, a state and constituent member of the North American republic. It is bounded by Florida and the Gdlf of Mexico on the south, the state of Mississippi on the west, Tennessee on the north, and Georgia on the east. Its length is 275 miles, breadth 185, and area 50,800 square miles. The country, to the extent of more than 100 miles from the coast, consists of uneven lands, of a poor sandy soil, bearing little except pines, but inter¬ spersed with marshes and alluvial tracts on the sides of the streams, which are extremely fertile. Higher up, the country becomes fertile and beautiful, and it bears that as¬ pect as far as the mountains occupying the northern part of the state. These mountains are about 50 miles in breadth, mid are supposed to exceed 1500 feet in height, but have peaks rising much higher. They are covered with a stony son, but on their southern side are many rich and beauti- u Vaileys, clothed with forests 'of oak, hickery, walnut, gum, and maple. Under the surface are mines of iron- ore. Ihe climate is very hot in the parts below the lati- tude of 32^, but comparatively temperate in the upper districts. At Fort Stodart, in latitude 31. the mean heat oy day was 84° or 86° in July, and from 43° to 79° in ebfuary. The principal river in the state is the Alabama, w uch is formed of two branches, the Tombeckbee, and 1 e Proper Alabama. The former rises in the state of A JL A 371 Mississippi, and after being joined by several streams, Alabarcha joins the Alabama at Fort Stodart. The Coosa and Tala- II poosa rivers united, compose the proper Alabama, which, Alabaster, after being joined by the Tombeckbee, falls into the Gulf"^^^* of Mobile at the latitude of 30A. All these rivers are navigable to a great distance from the sea. Steam-boats ply on the Alabama as far up as Montgomery, which is nearly 400 miles by water from Mobile Bay, but only 150 by land. The great employment of the people is agricul¬ ture. The soil yields wheat, maize, rye, barley, oats, and rice, and sugar-canes; but the principal object of culture is cotton, of which the state exports large quantities. The imports in 1824 amounted to 91,000 dollars, and the ex¬ ports to 460,000. The number of inhabitants in 1820 was 127,901, of whom 41,859 were slavesj and 571 free blacks. In January 1828 it was estimated at 254,000, including 93,000 slaves. This is exclusive of the Creek Indians, who were estimated at 20,000 in 1818. A great portion of the population consists of emigrants from Georgia. Cahawba, a small place, is the seat of government; but the only considerable town in the state is Mobile, which is situated on the west side of the bay of the same name, 30 miles from the Gulf of Mexico, and, in 1826, contained 5000 inhabitants. In 1816 some exiles from France re¬ ceived a grant of lands on the banks of the Tombeckbee, in this state, with the view of introducing the culture of the vine; but the project did not succeed, and the new settlement, named Demopolis, was abandoned in a few years. Alabama has very few made roads, and no canals, but by means of its numerous rivers it enjoys a great ex¬ tent of inland navigation ; and Mobile, the great centre of its trade, now communicates by steam-boats with all the considerable places on the Tombeckbee and Alabama rivers, and by sea with New Orleans. Alabama was ad¬ mitted to the rank of a state and member of the American union in 1819. Its government is vested in a house of representatives elected annually, a senate elected triennial- ly and renewed by thirds, and a governor elected for two years. The right of suffrage belongs to every white citizen of full age. The judges in this state hold their offices during good behaviour. Owing to the thinness of the population, education is yet in a backward state; but as a fund for its promotion, 640 acres of land are set apart in each township. In 1827 the public revenue amounted to 67,000 dollars, and the expenditure to 82,000. The country is healthful, except in the neighbourhood of wet grounds; and, upon the whole, Alabama possesses advan¬ tages over some of the other southern states, and is one of the most prosperous and rapidly progressive in that part of the union. (p.) ALABARCHA, in Antiquity, a kind of magistrate among the Jews of Alexandria, whom the emperor allow¬ ed them to elect, for the superintendency of their policy, and to decide differences and disputes which arose among them. ALABASTER, William, an English divine, was born at Hadley, in the county of Suffolk. He was one of the doctors of Trinity College in Cambridge; and he attended the earl of Essex as his chaplain in the expedition to Cadiz in the reign of Queen Elizabeth. It is said that his first resolutions of changing his religion were occasioned by his seeing the pomp of the churches of the Roman com¬ munion, and the respect with which the priests seemed to be treated amongst them; and appearing thus to waver in his mind, he soon found persons who took advantage of this disposition of his, and of the complaints which he made of not being advanced according to his deserts in England, in such a manner, that he did not scruple to go over to the Popish religion, as soon as he found that there 372 ALA ALA Alabaster was no ground to hope for greater encouragement in his jl own country. However that matter be, he joined himself Ihssara" t0 ^ie ^orn^1 communion; but was disappointed in his expectations. He was soon displeased at this; and he could not reconcile himself to the discipline of that church, which made no consideration of the degrees which he had taken before. It is probable, too, that he could not approve of the worship of creatures, which Protestants are used to look upon with horror. Upon this he returned to England in order to resume his former religion. Pie obtained a prebend in the cathedral of St Paul, and after that the rectory of Therfield in Hertfordshire. He was well skilled in the Hebrew tongue; but he gave a wrong turn to his genius by studying the Cabala, with which he was strangely infatuated. He gave a proof of this in a sermon which he preached upon taking his degree of doc¬ tor of divinity at Cambridge. He took for his text the beginning of the first book of Chronicles, “ Adam, Seth, Enos and having touched upon the literal sense, he turn¬ ed immediately to the mystical, asserting, that Adam sig¬ nified misfortune and misery, and so of the rest. His verses were greatly esteemed. He wrote a Latin tragedy, entitled Roxana, which, when it was acted in a college at Cambridge, was attended with a very remarkable acci¬ dent. There was a lady who was so terrified at the last word of the tragedy, Sequar, Sequar, which was pronoun¬ ced with a very shocking tone, that she lost her senses all her lifetime after. He died in the year 1640. His Ap¬ paratus in Revelationem Jesu Christi was printed at Ant¬ werp in 1607. His Spiracuhtm Tubarum, seuFons Spiritua- Imm Expositionum ex cequivocis Pentaglotti significationi- bus, and his Ecce Sponsm venit, seu Tuba Pulchritudinis, hoc est, Demonstratio quod non sit illicituin nec impossibile computare durationem fnundi et tempus secundi adventus Christi, were printed at London. From these titles we may judge what were the taste and genius of the author. Alabaster, in Natural History, a mineral substance whose base is calcareous earth. It differs from marble in being combined, not with the carbonic, but with the sul¬ phuric acid. Alabaster, m. Antiquity, a term used for a vase where¬ in odoriferous liquors were anciently put. The reason of the denomination is, that vessels for this purpose were frequently made of the alabaster stone, which Pliny and other ancients represent as peculiarly proper for this pur¬ pose. Several critics will have the box mentioned in the Gospels as made of alabaster to have been of glass; and though the texts say that the wnman broke it, yet the pieces seem miraculously to have been united, since we are told the entire box was purchased by the emperor Con¬ stantine, and preserved as a relic of great price. Others will have it that the name alabaster denotes the form rather than the matter of this box: in this view they de¬ fine alabaster by a box without a handle, deriving the word from the privative a, and Xa/3?j, ansa, handle. Alabaster is also said to have been used for an an¬ cient liquid measure, containing ten ounces of wine, or nine of oil. In this sense the alabaster was equal to half the sextary. ALABASTRUM Dendroide, a kind of laminated ala¬ baster, beautifully variegated with the figures of shrubs, trees, &c. found in great abundance in the province of Hohenstein. ALADINISTS, a sect among the Mahometans, answer¬ ing to freethinkers among us. ALADSCHAHISSAR, a Turkish pachalic (Sand- Sehah), part of the ancient Bulgaria, a mountainous dis¬ trict, in which the river Moravia rises in two branches, and runs into the Danube. It extends from long. 21. 45. to 22. 30. E. and from lat. 42.30. to 43.30. N. Thegreatroad }■ ju from Belgrade passes through the northern part of the pro- ' vince. It is productive of wine, feeds much cattle, and A1n?ai has some rivers near Camplina. The capital, of the same^ ^ name, sometimes called Kruschevarz, is the seat of a Greek bishop, and has a castle; once the residence of the predatory chief Von Serf, and conquered from him by the Sultan Murad the Second. It is near the east bank of the river Moravia. ALADULIA, a considerable province of Turkey in Asia, in that part called Natolia, between the mountains of Antitaurus, which separate it from Amasia on the north, and from Caramania on the west. It has the Me¬ diterranean Sea on the south ; and the Euphrates or Frat on the east, which divides it from Diarbekir. It compre¬ hends the Lesser Armenia of the ancients, and the east part of Cilicia. Formerly it had kings of its own; but the head of the last king was cut olf by Selim I. emperor of the Turks, who had conquered the country. It is now di¬ vided into two parts: the north, comprehended between Taurus, Antitaurus, and the Euphrates, is a beglerbeglic, which bears the name of Marash, the capital town; and the south, seated between Mount Taurus and the Medi¬ terranean, is united to the beglerbeglic of Aleppo. The country is rough, rugged, and mountainous ; yet there are good pastures, and plenty of horses and camels. The peo¬ ple are hardy and thievish. The capital is Malatigah. ALAIN, Chartier, secretary to Charles VII. king of France, born in the year 1386. He was the author of several works in prose and verse; but his most famous performance was his Chronicle of King Charles VII. Ber¬ nard de Girard, in his preface to the History of France, styles him “ an excellent historian, who has given an ac¬ count of all the affairs, particulars, ceremonies, speeches, answers, and circumstances, at which he was present him¬ self, or had information of.” Giles Coroxet tells us that Margaret, daughter to the king of Scotland, and wife to the dauphin, passing once through a hall where Alain lay asleep, she stopped and kissed him before all the company who attended. Some of them telling her, that itwas strange she should kiss a man wrho had so few charms in his per¬ son, she replied, “ I did not kiss the man, but the mouth from whence proceed so many excellent sayings, so many wise discourses, and so many elegant expressions. Mr Fontenelle, among his Dialogues of the Dead, has one upon this incident, between the princess Margaret and Plato. Mr Pasquier compares Alain to Seneca, on account of the great number of beautiful sentences interspersed throughout his writings. ALAJOR, a Spanish town, in the island of Minorca, and the province of Majorca, the chief town of a district containing 3950 inhabitants. ALAIS, an arrondissement in the department of the Gard, in France, extending over 480 square miles, or 307,200 acres. It is divided into nine cantons, and ninety-nine communes, and contains 68,223 inhabitants. Alais, a city, and chief of the arrondissement of the same name. It is situated on the river Gardon, at the foot of the Cavennes. It contains 9380 inhabitants, who are employed in manufacturing ribbons, sewing-silk, silk- hosiery, cotton-goods, glass, porcelain, and other articles. Long. 3. 29. 40. E. Lat. 44. 7. N. ALAMAGAN, one of the Ladrone or Marianne islands, in the Indian Ocean, is situated in long. 146. 4/. lat. 18. 5. N. It is of an irregular form, and about ~ miles in circumference. The land in some places of t as island is pretty high, so that it may be seen at the tance of 12 or 14 leagues. Near the north end or ie island there is a volcano, which emitted an immense bo ) ALA i m v ^infancy, before they were tutored to this deceit, and when too few people came to Chamouni to make this affectation profitable to them, can attest that then they were not very much offended with the light of day. At that time they were so little desirous of exciting the curiosity of strangers, that they hid themselves to avoid such; and it was necessary to do a sort of violence to them before they could be prevailed on to allow themselves to be in¬ spected. It is also well known at Chamouni, that when they were of a proper age they were unable to tend the cattle like the other children at the same age; and that one of their uncles maintained them out of charity, at a time of life when others were capable of gaining a subsis¬ tence by their labour. “ I am therefore of opinion, that we may consider these two lads as two albinos; for if they have not the thick lips and flat noses of the white negroes, it is because they are albinos of Europe, not of Africa. This infirmity affects tlie eyes, the complexion, and the colour of the hair; it even diminishes the strength, but does not alter the con¬ formation of the features. Besides, there are certainly in this malady various degrees—some may have less strength, and be less able to endure the light; but these circum¬ stances in those of Chamouni are marked with characters sufficiently strong to entitle them to the unhappy advan¬ tage of being classed with that variety of the human spe¬ cies denominated albinos. “ When nature presents the same appearance often, and with circumstances varied, we may at last discover some general law, or some relation which that appearance has with known causes; but when a fact is so singular and so rare as that of those albinos, it gives but little scope to a conjecture; and it is very difficult to verify those by which we attempt to explain it. “ I at first imagined that this disease might be referred to a particular sort of organic debility; that a relaxation of the lymphatic vessels within the eye might suffer the globules of the blood to enter too abundantly into the iris, die uvea, and even into the retina, which might occasion the redness of the iris and of the pupil. The same de¬ bility seemed also to account for the intolerance of the light, and for the whiteness of the hair. “ But a learned physiologist, M. Blumenbaeh, professor in the university of Gottingen, who has made many pro¬ found observations on the organs of sight, and has consid¬ ered with great attention the albinos of Chamouni, attri¬ butes their infirmity to a different cause. “ The study of comparative anatomy has furnished him with frequent opportunities of observing this phenomenon; he has found it in brutes, in white dogs, and in owls ; he says it is generally to be seen in the warm-blooded ani¬ mals, but that he has never met with it in those with cold blood. “ From his observations, he is of opinion that the red¬ ness of the iris, and of the other internal parts of the eye, as well as the extreme sensibility that accompanies this redness, is owing to the total privation of that brown or blackish mucus, which, about the fifth week after concep¬ tion, covers all the interior parts of the eye in its sound state. He observes that Simon Pontius, in his treatise de (oloribus Oculorum, long ago remarked, that in blue eyes the interior membranes were less abundantly provided with this black mucus, and were therefore more sensible to the action of light. This sensibility of blue eyes agrees very well, says M. Blumenbach, with northern people, during their long twilight; w hile, on the contrary, the deep black in the eyes of negroes enables them to support the splendour of the sunbeams in the torrid zone. alb 383 “ As to the connection between this red colour of their Albinos, eyes and the whiteness of the skin and hair, the same^-^v^-^ learned physiologist says, that it is owing to a similarity of structure, consensus ex similitudine fabricee. He asserts that this black mucus is formed only in the delicate cellu¬ lar substance, which has numerous blood-vessels contigu¬ ous to it, but contains no fat, like the inside of the eye, the skin of negroes, the spotted palate of several domestic animals, &c. And, lastly, he says that the colour of the hair generally corresponds with that of the iris. ( Gazette Litt. de Gottingue, Oct. 1784.) “ At the very time that M. Blumenbach was reading this memoir to the Royal Society of Gottingen, M. Buzzi, surgeon to the hospital at Milan, an eleve of the celebrated anatomist Moscati, published in the Opuscoli Scelti de Milan, 1784, tom. vii. p. 11, a very interesting memoir, in which he demonstrates by dissection what Blumenbach had only supposed. “ A peasant of about 30 years of age died in the hospi¬ tal of Milan of a pulmonary disorder. His body being exposed to view, was exceedingly remarkable by the un¬ common whiteness of the skin, of the hair of the beard, and of all the other covered parts of the body. M. Buzzi, who had long desired an opportunity of dissecting such a subject, immediately seized upon this. He found the iris of the eyes perfectly wdiite, and the pupil of a rose colour. The eyes were dissected with the greatest possible care, and were found entirely destitute of that black membrane which anatomists call the uvea; it was not to be seen either behind the iris or under the retina. Within the eye there wyas only found the choroid coat, extremely thin, and tinged of a pale red colour, by vessels covered with dis¬ coloured blood. WTiat was more extraordinary, the skin, when detached from different parts of the body, seemed almost entirely divested of the rete mucosum; maceration did not discover the least vestige of this, not even in the WTinkles of the abdomen, where it is most abundant and most visible. “ M. Buzzi likewise accounts for the whiteness of the skin and of the hair, from the absence of the rete mucosum, which, according to him, gives the colour to the cuticle, and to the hairs that are scattered over it. Among other proofs of this opinion, he alleges a well-known fact, that if the skin of the blackest horse be accidentally destroyed in any part of the body, the hairs that afterwards grow on that part are always white, because the rete mucosum which tinges those hairs are never regenerated with the skin. “ The proximate cause of the whiteness of albinos, and the colour of their eyes, seems therefore pretty evidently to depend on the absence of the rete mucosum ; but what is the remote cause ? “ In the first place, it seems probable that men affected with this infirmity form no distinct species, for they are produced from parents that have dark skins and black eyes. What is it then that destroys the rete mucosum in such persons? M. Buzzi relates a singular fact, which seems to throw some light on this subject. “ A woman of Milan, called Calcagni, had seven sons. The two oldest had brown hair and black eyes; the three next had white skins, white hair, and red eyes; the two last resembled the two eldest. It was said that this woman, during the three pregnancies that produced the albinos, had a continual and immoderate appetite for milk, which she took in great quantities ; but that when she was with child of the other four children, she had no such desire. It is not, however, ascertained that this preternatural ap¬ petite was not itself the effect of a certain heat, or internal disease, which destroyed the rete mucosum in the children before they were born. 384 ALB ALB Albino- “ The albinos of Chamouni are also the offspring of pa- vanus rents with dark skins and black eyes. They have three sisters A1 bin us ^3r t^le same father and mother, who are also brunettes. One of them that I saw had the eyes of a dark brown, and the hair almost black. They are said, however, to be all afflicted with a weakness of sight. When the lads are married, it will be curious to observe how the eyes of their children will be formed. The experiment would be par¬ ticularly decisive if they were married to women like themselves. But this faulty conformation seems to be more rare among women than among men; for the four of Milan, the two of Chamouni, the one described by Mau- pertuis, the one by Helvetius, and almost all the instances of these singular productions, have been of our sex. It is known, however, that there are races of men and wo¬ men affected with this disease, and that these races per¬ petuate themselves in Guinea, in Java, at Panama, &c. “ Upon the whole, this degeneration does not seem to be owing to the air of the mountains; for though I have traversed the greatest part of the Alps, and the other mountains of Europe, these are the only individuals of that kind that I ever met with.” ALBINOVANUS, a Latin poet, whom Ovid surnamed the Divine. There is now nothing of his extant, except an elegy on Drusus, and another on the death of Mecaenlir. ALBINUS, Bernhard Siegfred, a celebrated phy¬ sician and anatomist, was born of an illustrious family at Frankfort on the Oder in 1697. His father was then pro¬ fessor of the practice of medicine in the university of Frankfort; but in the year 1702 he repaired to Leyden, being nominated professor of anatomy and surgery in that university. Here his son had an opportunity of studying under the most eminent masters in Europe, who, from the singular abilities which he then displayed, had no difficulty in prognosticating his future eminence. But while he was distinguished in every branch of literature, his atten¬ tion was particularly turned to anatomy and surgery. His peculiar attachment to these branches of knowledge gain¬ ed him the intimate friendship of Buysch and Rau, who at that time flourished in Leyden; and the latter, so justly celebrated as a lithotomist, is said to have seldom perform¬ ed a capital operation without inviting him to be present. Having finished his studies at Leyden, he went to Paris, where he attended the lectures of Du Verney, Vaillant, and other celebrated professors. But he had scarce spent a year there when he was invited by the curators of the university of Leyden to be a lecturer on anatomy and sur¬ gery at that place. Though contrary to his own inclina¬ tion, he complied with their request, and upon that occa¬ sion was created doctor of physic without any examination. Soon after, upon the death of his father, he was appoint¬ ed to succeed him as professor of anatomy; and upon being admitted into that office on the 9th of November 1721, he delivered an oration, De vera via ad fabricae hu- mani corporis cognitionem ducente, which was heard with universal approbation. In the capacity of a professor, he not only bestowed the greatest attention upon the instruc¬ tion of the youth intrusted to his care, but on the improve¬ ment of the medical art. With this view he published many important discoveries of his own, and by elegant editions turned the attention of physicians to works of merit, which might otherwise have been neglected. By these means his fame was soon extended over Europe; and the societies of London, Petersburg, and Haerlem, cheerfully received him as an associate. In 1745 he was appointed professor of the practice of medicine at Leyden, and was succeeded in the anatomical chair by his brother Frid. Bern. Albinus. He was twice rector of the univer¬ sity, and as often he refused that high honour when it was voluntarily offered him. At length, worn o vice and intense study, he died on the 9th 1770, in the 74th year of his age. ALBION, the ancient name of Britain. New Albion, a name given by Sir Francis Drake to California, on the north-west coast of America, which he discovered and took possession of in the year 1578. Can tain Cook visited this coast in 1778, and landed in a place situated in long. 235. 20. E. lat. 44. 33. N. In the year 1792 it was again visited by Captain Vancouver, who was employed in surveying the western coast of North Ame¬ rica. The name is now applied to a country farther north than California, but without any definite boundaries. ALBIREO, in Astronomy, a star of the third or fourth magnitude, in the constellation Cygnus. ALBIS, in Ancient Geography, now the Elbe, which di¬ vided ancient Germany in the middle, and was the boun¬ dary of this country, so far as it was known to the Romans • all beyond they owned to be uncertain, no Roman except Drusus and Tiberius having penetrated so far as the Elbe. ALBISOLA, a small town belonging to the republic of Genoa. Here is a porcelain manufacture, and several country-houses of the Genoese nobility. It was bombard¬ ed in 1745 by the English. Long. 8. 20.

ALBOGALERUS, in Roman Antiquity, a white cap worn by the fiamen Dialis, on the top of which was an or¬ nament of olive branches. ALBORAK, amongst the Mahometan writers, the beast on which Mahomet rode in his journeys to heaven. The Arab commentators give many fables concerning this ex¬ traordinary mode of conveyance. It is represented as of an intermediate shape and size between an ass and a mule. A place, it seems, was secured for it in paradise at the in¬ tercession of Mahomet; which, however, was in some measure extorted from the prophet, by Alborak’s refusing to let him mount when the angel Gabriel was come to con¬ duct him. ALBORO, in Zoology, a name by which the erythrinus, a small red fish caught in the Mediterranean, is common¬ ly known in the markets of Rome and Venice. ALBOURG, a town of Denmark, in North Jutland, capital of the diocese of the same name, and a bishop's see. It has this name, which signifies eel-town, on account of the great number of eels taken here. It is seated on a canal 10 miles from the sea, 30 north of Wiburg, and 50 north of Aarhuus. It has an exchange for merchants, and a safe and deep harbour. They have a considerable trade in herrings and corn, and a manufactory of guns, pistols, saddles, and gloves. Long. 9. 50. E.

N. h\a ■ ALBUM, in Antiquity, a kind of white table or register, wherein the names of certain magistrates, public transac¬ tions, &c. were entered. Of these there were various sorts • as the album decurionum, album senatorum, album judicum, album prcetoris, &c. Album Decurionum was the register wherein the names of the decuriones were entered. This is otherwise called mtriculatio decurionum. Album Senatorum, the list of senators’ names, which was first introduced by Augustus, and renewed yearly. Album Judicum, that wherein the names of the persons of those who judged at certain times were entered. Album Prcetoris, that wherein the formulae of all ac¬ tions, and the names of such judges as the pretor had chosen to decide causes, were written. The high-priest entered the chief transactions of each year into an album, or table, which was hung up in his house for the public use. Album is also used, in later times, to denote a kind of table, or pocket-book, wherein the men of letters with whom a person has conversed inscribed their names, with some sentence or motto. Album Graecum, the white dung of dogs, formerly pre¬ scribed for inflammations of the throat, &c. but now disused, and chiefly employed by leather-dressers to soften leather after the application of lime. ALBUMAZAR, a learned Arabian astronomer in the tenth century, who wrote a treatise Of the Devolution of the Years. ALBUMEN, a substance found both in animal and vegetable matters, and in great abundance in the white of eggs. ALBUQUERQUE, a town of Spain, in the province of Estremadura, is seated on an eminence, nine miles from the frontiers of Portugal, and containing 5500 inhabitants. It is commanded by an almost impregnable fortress, built on a high mountain, and serving to defend the town. It has some trade in wool and woollen manufactures. It was taken by the allies of Charles king of Spain in 1705. Long. 7. 0. W. Lat. 38. 52. N. ALBURN, the English name of a compound colour, being a mixture of white and redPbr reddish brown. Skinner derives the word, in this sense, from the Latin abm, and the Italian burno, from bruno, brown. ALBURNUM, the soft white substance which in trees is found between the liber or inner bark and the wood, and in process of time acquiring solidity, becomes itself the wood. From its colour and comparative softness, it has been styled by some writers the fat of trees, adepts arborum.

Horace seems to think him i it inventor of this kind of poesy. Now the Homan muse inspire, And warm the song with Grecian fire.

Horace, who of all the Latin poets most resembled Alcaeus, has made Ak-mis the like confession : h With thee I saw Philippi’s plain, Its fatal rout, a fearful scene! And dropp’d, alas ! th’ inglorious shield. Where valour’s self was forc’d to yield ; Where soil’d in dust the vanquish’d lay, And breath’d th’ indignant soul away. .Francis. Alcaics. The poetical abilities of Alcaeus are indisputable; and though his writings were chiefly in the lyric strain, yet his muse was capable of treating the sublimest subjects with a suitable dignity. Hence Horace says, Alcaeus strikes the golden strings, And seas, and war, and exile, sings. Thus while they strike the various lyre, The ghosts the sacred sounds admire; But when Alcaeus lifts the strain To deeds of war and tyrants slain. In thicker'crowds the shadowy throng Drink deeper down the martial song. Francis. Alcaeus, an Athenian tragic poet, and, as some think, the first composer of tragedies. He renounced his native country Mitylene, and passed for an Athenian. He left 10 pieces, one of which was Pasiphae, that which he pro¬ duced when he disputed with Aristophanes, in the 4>th year of the 97th Olympiad. There is another Alcjeus mentioned in Plutarch, per¬ haps the same whom Porphyrius mentions as a composer of satirical iambics and epigrams, and who wrote a poem concerning the plagiarism of Euphorus the historian. He lived in the 145th Olympiad. We are told likewise of one Alcteus, a Messenian, who lived in the reign of Vespasian and Titus. We know not which of these it was who suffered for his lewdness a very singular kind of death, which gave occasion to the follow¬ ing epitaph: KKhuiov ratpos oirts, See. This is Alcaeus’s tomb, who died by a radish, The daughter of the earth, and punisher of adulterers. This punishment, inflicted on adulterers, was thrusting one of the largest radishes up the anus of the adulterer ; or, for want of radishes, they made use of a fish with a very large head, which Juvenal alludes to: Quosdam machos ct mugilis intrat. Sat. x. The mullet enters some behind. Hence we may understand the menace of Catullus: Ah ! turn te miserum, malique fati. Quern attractis pedibus, patente porta, Percurrent raphanique, mugilesque. Epig. xv. Ah! wretched thou, and born to luckless fate, Who art discover’d by the unshut gate ! If once, alas! the jealous husband come. The radish or the sea-fish is thy doom. ALCAICS, in Ancient Poetry, a denomination given to several kinds of verse, from Alcaeus, their inventor. The first kind consists of five feet, viz. a spondee or iambic, an iambic, a long syllable, a dactyle, another dac- tyle. Such is the following verse of Horace: Omnes | eo\dem | coghnur, | omnium Versa\tur ur\na ] serins, \ ocius, Sors exitura. The second kind consists of two dactyles and two tro¬ chees; as, Exili\uni imposi\tura | cymbee. Besides these two, which are called dactylic Alcaics, there is another, simply styled Alcaic, consisting of an 3 c 386 A L C A L C Alcaic epitrite, a choriambus, another choriambus, and a bac- II chins. The following is of this species : Alcantara- Cur timet Jla\vum Tiberim | tang ere, cur | olivum $ Alcaic Ode, a kind of manly ode, composed of several strophes, each consisting of four verses; the first two of which are always alcai'cs of the first kind ; the third verse is a dimeter hypercatalectic, or consisting of four feet and a long syllable; and the fourth verse is an alca’ic of the second kind. The following strophe is of this species, which Horace calls minaces Alccei camence. Non possidentem multa •vocaveris Recte beatum; rcctius occupat Nomen beati, qui deorum Muneribus sapienter uti, &C. ALCAID, Alcayde, or Alcalde, in the polity of the Moors, Spaniards, and Portuguese, a magistrate or officer of justice, answering nearly to the French provost and the British justice of peace. The alcaid among the Moors is vested with supreme jurisdiction, both in civil and criminal cases. ALCALA de Guadeira, a small town of Spain, in Andalusia, upon the river Guadeira.

It was founded by Cardinal Ximenes; and one of its first and best productions has been the Complutensian edition of the Holy Scriptures, which was prepared here. The river Henares runs by the city, and gives its distinguish¬ ing name. Here is also a military school for the artillery and engineer corps; 1600 houses, 4760 inhabitants. Its powder-mills produce 15 cwt. annually. Alcala-HcoI, a small city of Spain, in Andalusia, with a fine abbey.

ALC ANIZ, a Spanish town upon the Guadaloupe, in the province of Arragon, with a college, three parish churches, six monasteries, one hospital, and 4200 inhabitants. The surrounding country is wild, but rich in olives, mulberry trees, and alum. ALCANNA, or Alkanna, in Commerce, a powder prepared from the leaves of the Egyptian privet, in which the people of Cairo drive a considerable trade. It is much used by the Turkish women, to give a golden colour to their nails and hair. In dyeing, it gives a yellow colour when steeped with common water, and a red one when infused in vinegar. There is also an oil extracted from the berries of alcanna, which is sometimes used in medi- . cine.

It has two parish churches, five monasteries, and 3000 inhabitants. Knights of Alcantara, a military order of Spain, which Ale took its name from the above-mentioned city. They make a very considerable figure in the history of the expeditions A1 against the Moors. The knights of Alcantara make the''"'’ same vows as those of Calatrava, and are only distinguished from them by this, that the cross fleur de lis, which they bear over a large white cloak, is of a green colour. They possess 37 commanderies. By the terms of the surrender of Alcantara to this order, it was stipulated that there should be a confraternity between the two orders, with the same practices and observances in both; and that the order of Alcantara should be subject to be visited by the grand master of Calatrava. But the former soon released themselves from this engagement, on pretence that their grand master had not been called to the election of that of Calatrava, as had been likewise stipulated in the arti¬ cles. After the expulsion of the Moors, and the taking of Granada, the sovereignty of the order of Alcantara and that of Calatrava was settled in the crown of Castile by Ferdinand and Isabella. In 1540 the knights of Alcantara sued for leave to marry, which was granted them. ALCARAZ, a small city of La Mancha, in Spain, de¬ fended by a pretty strong castle, and remarkable for an ancient aqueduct. It stands near the river Guardamena, and the soil about it is very fruitful. They have a breed of little running horses, which are very fleet and strong.

The fields produce large quantities of a sort of rushes, of which they make mats, which are transported out of the kingdom. Long. 9. 10. W. Lat. 38. 18. N. Alcassar, a city of Barbary, seated about two leagues from Larache, in Asga, a province of the kingdom of Fez. It was of great note, and the seat of the governor of this part of the kingdom. It was built by Jacob Al- manzor, king of Fez, about the year 1180, and designed for a magazine and place of rendezvous for the great pre¬ parations he was making to enter Granada in Spain, and to make good the footing which Joseph Almanzor had got some time before. It is said his father first invaded Spain with 300,000 men, most of whom he was obliged to bring back to Africa to quell a rebellion that had broke out in Morocco. This done, he returned to Spain again with an army, as is said, of 200,000 horse and 300,000 foot. Ihe city is now fallen greatly to decay, so that of fifteen mosques there are only two that they make use of. Ihy reason, probably, is the bad situation of the town; for it stands so low, that it is excessively hot in summer, an almost overflowed with water in the winter. Ibis they affirm to be owing to the curse of one of their smnts. Flere are a great number of storks, which live very familiar} with the people, walking about the town, possessing t e tops of the houses and mosques without molestation; ()1 they esteem them sacred birds, and account it sintu o disturb them.

ALCAVALA, in the Spanish Finances, was at first a tax of 10 per cent., afterwards of 14 per cent., and is at present of only 6 per cent., upon the sale of every sort of property, whether movable or immovable; and it is repeated every time the property is sold. The levying of this tax requires a multitude of revenue officers sufficient to guard the transportation of goods, not only from one province to another, but from one shop to another. It subjects not only the dealers in some sort of goods, but those in all sorts, every farmer, every manufacturer, every merchant and shopkeeper, to the continual visits and ex¬ amination of the tax-gatherers. Through the greater part of a country in which a tax of this kind is established, nothing can be produced for distant sale. The produce of every part of the country must be proportioned to the consumption of the neighbourhood. It is to the Alcavala, accordingly, that Ustaritz imputes the ruin of the manu¬ factures of Spain. He might have imputed to it likewise the declension of agriculture, it being imposed not only upon manufacturers, but upon the rude produce of the land. ALCAZAR de St Juan, a city on the border of a small lake, in the province of Toledo, in Castile. It con¬ tains 2200 inhabitants. It has a saltpetre refinery, and some gunpowder works. Alcazar Leguer, a town of Africa, in the kingdom of Fez, and in the province of Rabat. It was taken by Al- phonso, king of Portugal, in 1468; but soon after that it was abandoned to the Moors. It is seated on the coast of the straits of Gibraltar. Long. 3. 50. W. Lat. 38. 0. N. ALCHEMY, that branch of chemistry which had for its principal objects the transmutation of metals into gold, the panacea or universal remedy, an alkahest or univer¬ sal menstruum, an universal ferment, and many other things equally ridiculous. — Kircher, instructed in all the secrets of chemistry, has fully exposed the artifices and impostures of alchemists. An alchemist puts into a crucible the matter which is to be converted into gold: this he sets on the fire, blows it, ''tus it with rods, and, after divers operations, gold is ound at the bottom of the crucible, instead of the matter first put in. This there are a thousand ways of effecting, " ithout any transmutation. Sometimes it is done by dex¬ terously dropping in a piece of gold concealed between t ic fingers; sometimes by casting in a little of the dust u gold or silver, disguised under the appearance of some e ixir, or other indifferent matter; sometimes a crucible usec^ which has a double bottom, and gold put between Uj two; sometimes the rod used to stir the matter is 10 <>w, and filled with the dust of the metal desired; at °t ter times there is metal mixed with the charcoal, the as ,es °/ j-he furnace, or the like.

Rymer furnishes us with a Alcmaer. licence^ for practising alchemy, with all kinds of metals and minerals, granted to one Richard Carter in 1476. (Rym. Feed. tom. xii.) Nevertheless we have had severe laws against alchemy, and multiplying of metals, as much so as against coining itself. ALCIAF, or Alciate, Andrew, a great lawyer, who flourished in the 10th century, was born at Milan. He mixed much of polite learning in the explication of the laws, and happily drove out the barbarity of language which till then had reigned in the lectures and writings of lawyers; for which Thuanus highly praises him. He published a great many law-books, and some notes upon Tacitus. His Emblems have been much admired, and translated into French, Italian, and Spanish; and several learned men have written commentaries on them. ALCIBIADES, an Athenian general. It was the fate of this great man to live at a time when his country was a scene of confusion. The Greeks, grown insolent from their conquests in Persia, turned their armies against each other, and bandied together under the conduct of the two most opulent states, Athens and Lacedemon. Alcibiades, in the midst of an expedition he had planned against the enemies of his country, was recalled home to answer some charge of a private nature; but fearing the violence of his enemy, instead of going to Athens, he offered his ser¬ vices at Sparta, where they were readily accepted. By his advice the Lacedemonians made a league with Persia, which gave a very favourable turn to their affairs. But his credit in the republic raising jealousies against him, he privately reconciled himself to his country, and took again the command of the Athenian army. Here victory, waiting as it were at his command, attended all his mo¬ tions. The loss of seven battles obliged the Spartans to sue for peace. He enjoyed his triumphs, however, only a short time at Athens. One unsuccessful event made him again obnoxious to the malice of his citizens, and he found it expedient to retire from Athens. In his absence the Spartans again took the lead, and at the fatal battle of iEgos entirely subdued the Athenian power. Alcibiades, though an exile, endeavoured to restore the power of his country; of which the Spartans having intelligence, pro¬ cured him to be assassinated. He was a man of admirable accomplishments, but indifferently principled; of great parts, and of an amazing versatility of genius. ALCINOUS, king of the Phseacians, in the island now called Corfu, was son of Nausithous, and grandson of Neptune and Periboea. It is by his gardens that this king has chiefly immortalized his memory. He received Ulysses with much civility, when a storm had cast him on his coast. The people here loved pleasure and good cheer, yet were skilful seamen; and Alcinous was a good prince. ALCIRA, a Spanish town upon an island in the river Xucar, in the province of Valencia. It is surrounded with walls, and has two parish churches, six monasteries, one hospital, four poor-houses, and 9000 inhabitants. ALCMAER, a city of the United Provinces, seated in North Holland, about four miles from the sea, 15 from Haerlem, and 18 from Amsterdam. The streets and houses are extremely neat and regular, and the public buildings very beautiful. It had formerly two parish churches, dedicated to St Matthew and St Lawrence. The latter had so high a tower, that it served for a sea¬ mark to the vessels that were in the open sea; but in 1464 it tumbled down, aud damaged the other church so much that they were both demolished in 1670, and one church was built in their stead, dedicated to the same 388 A L C Aleman saints. The Spaniards, under the command of Frederick I! of Toledo, son of the duke of Alva, came to besiege it, Alcock. afj;er they had taken Haerlem in 1573 ; but were forced to raise the siege after lying three months before it, as well on account of the infection of the air, as the stout re¬ sistance of the inhabitants and soldiers; even the women signalizing themselves bravely in its defence. It is re¬ corded in the register of this city, that, in the year 1637, 120 tulips, with the offsets, sold for 90,000 florins. The town has a very great trade in butter and cheese. It was taken by the British in 1799, but soon abandoned. Long. 4. 26. E. Lat. 52. 28. N. ALCMAN, a lyric poet, who flourished in the 27th Olympiad, about 670 years before Christ. He was born at Sparta, and composed several poems, of which only some fragments are remaining, quoted by Athenaeus and some other ancient writers. He was very amorous, accounted the father of gallant poesy, and is said to have been the first that introduced the custom of singing love- songs in company. He is reported to have been one of the greatest eaters of his age; upon which Mr Bayle remarks, that such a quality would have been extremely inconve¬ nient, if poetry had been at that time upon such a footing as it has been often since, not able to procure the poet bread. He died of a strange disease, for he was eaten up with lice. ALCMANI AN, in ancient lyric poetry, a kind of verse, consisting of two dactyles and two trochees: as,— Virgini\bus pue\risque\canto. The word is formed from Aleman, the name of an ancient Greek poet in great esteem for his erotics or amorous compositions. ALCMENA, the daughter of Electryo, king of My¬ cenae, and wife of Amphitryon. Jupiter, putting on the shape of her husband while he was abroad in the wars, begot Hercules upon her: he made that night as long as three ordinary ones. ALCOBAZA, a town of Portugal, to the north of Lis¬ bon, in the province of Estremadura, at the mouth of the two rivers Alcoa and Baza. It is celebrated for its mo¬ nastery, one of the richest and most splendid establish¬ ments in the kingdom. It contains 295 houses and 1500 inhabitants. ALCOCK, John, doctor of laws, and bishop of Ely in the reign of King Henry VII., was born at Beverley in Yorkshire, and educated at Cambridge. He was first made dean of Westminster, and afterwards appointed master of the rolls. In 1471 he was consecrated bishop of Rochester: in 1476 he was translated to the see of Worcester; and in 1486 to that of Ely, in the room of Dr John Morton, preferred to the see of Canterbury. He was a prelate of great learning and piety, and so high¬ ly esteemed by King Henry, that he appointed him lord- president of Wales, and afterwards lord-chancellor of England. Alcock founded a school at Kingston-upon- Hull, and built the spacious hall belonging to the epis¬ copal palace at Ely. He was also the founder of Jesus College in Cambridge, for a master, six fellows, and as many scholars. This house was formerly a nunnery, de¬ dicated to St Radigund; and, as Godwin tells us, the building being greatly decayed, and the revenues reduced almost to nothing, the nuns had all forsaken it, except two; whereupon Bishop Alcock procured a grant from the crown, and converted it into a college. But Camden and others tell us, that the nuns of that house were so notorious for their incontinence, that King Henry VII. and Pope Julius II. consented to its dissolution: Bale ac¬ cordingly calls this nunnery spiritualium meretricum cceno- A L C Mum, a community of spiritual harlots. Bishop Alcock a wrote several pieces, among which are the following:— 1. Mons Perfectionis; 2. In Psalmos Pcenitentiales • - 3. Homilias Vulgares; 4. Meditationes Pise. He died 0c> tober 1. 1500, and was buried in the chapel he had built at Kingston-upon-Hull. ALCOENTRE, a town of Portugal, in the province of Estremadura. It is within the lines of Torres Vedras, and was occupied by the allied troops as cantonments during the important period when those lines were the barrier that secured the safety of the peninsula. ALCOHOL, or Alkool, in Chemistry, spirits of wine highly rectified. It is also used for any highly rectified spirit. Alcohol is also used for any fine impalpable powder. ALCOHOLIZATION, the process of rectifying any spirit. It is also used for pulverization. ALCOOMETER, or Alkoometer, a name given by Richter to the hydrometer with a graduated stalk. See Areometer. ALCOR, the name of a small star adjoining to the large bright one in the middle of the tail of Ursa major. The word is Arabic. It is a proverb among the Arabians, ap¬ plied to one who pr*etends to see small things, but overlooks much greater: Thou canst see Alcor, and yet not see tliefull moon. ALCOR A, a town of Spain, in the province of Valencia. It is situated on a small river that runs into the Mijares, and is principally to be noted for its potteries, in which earthenware of various kinds and china are extensively manufactured. It contains 2400 inhabitants, and is situated atrt :raj, in lat. 42. 2. N. ALCORAN, or Al-koran, the scripture or bible of the Mahometans. The word is compounded of the Arabic par¬ ticle al, and coran or horan, derived from the verb caraa or haraa, to read. It therefore properly signifies the read¬ ing, or rather that which ought to be read. By this name the Mahometans denote not only the entire book or volume of the Koran, but also any particular chapter or section of it; just as the Jews call either the whole Scripture, or any part of it, by the name of Karah or Mikra, words of the same origin and import. Besides this peculiar name, the Koran is also honoured with several appellations common to other books of Scrip¬ ture : as al Farkan, from the verb foraka, to divide or dis¬ tinguish ; not, as the Mahometan doctors say, because those books are divided into chapters or sections, or distinguish between good and evil, but in the same notion that the Jews use the word Pereh or Pirka, from the same root, to denote a section or portion of Scripture. It is also called al Moshaf, the volume, and al Kitah, the book, by way of eminence, which answers to the Piblia of the Greeks; and al Dhikr, the admonition, which name is also given to the Pentateuch and Gospel. The Koran is divided into 114 larger portions of verj unequal length, which we call chapters, but the Arabians soicar, in the singular sura, a word rarely used on any other occasion, and properly signifying a row, order, or a regular series; as a course of bricks in a building, or a rank ox so - diers in an army; and is the same in use and import wit i the Sura or Tora of the Jews, who also call the fifty-three sections of the Pentateuch Sedarim, a word of the same signification. _ . f These chapters are not distinguished in the manuscrip copies by their numerical order, but by particular tit es, which are taken sometimes from a particular matter trea ed of, or person mentioned therein; but usually from first word of note, exactly in the same manner as the e have named their Sedarim; though the word from w u I ALCORAN. 389 i]COj.some chapters are denominated be vexy far distant, towards fess, has not been communicated to any mortal, their nro- Aicoran the middle, or perhaps the end of the chapter; which phet only excepted.

A L C \lc; n. same disorder, and not digested into the method, such as is, in which we now find them. This was the work of his successor Abu Beer, who, considering that a great number of passages were committed to the memory of Mahomet’s followers, many of whom were slain in their wars, ordered the whole to be collected, not only from the palm-leaves and skins on which they had been written, and which were kept between two boards or covers, but also from the mouths of such as had gotten them by heart. And this transcript, when completed, he committed to the custody of Hassa, the daughter of Omar, one of the pro¬ phet’s widows. From this relation it is generally imagined that Abu Becrwas really the compiler of the Koran, though, for aught that appears to the contrary, Mahomet left the chapters complete as we now have them, excepting such passages as his successor might add or correct from those who had gotten them by heart; what Abu Beer did else being perhaps no more than to range the chapters in their pre¬ sent order, which he seems to have done without any re¬ gard to time, having generally placed the longest first. However, in the 30th year of the Hegira, Othman being then caliph, and observing the great disagreement in the copies of the Koran in the several provinces of the empire,— those of Irak, for example, following the reading of Abu Musa al Ashari, and the Syrians that of Macdad Ebn Aswad,—he, by the advice of the companions, ordered a great number of copies to be transcribed from that of Abu Beer, in Hassa’s care, under the inspection of Zeid Ebn Thabet, Abdallah Ebn Zobair, Said Ebn al As, and Abd’al- rahman Ebn al Hareth the Makhzumite ; whom he direct¬ ed, that wherever they disagreed about any word, they should write it in the dialect of the Koreish, in which it was at first delivered. These copies, when made, were dispersed in the several provinces of the empire, and the old ones burnt and suppressed. Though many things in Hassa’s copy were corrected by the above-mentioned re¬ visers, yet some few various readings still occur. “ The most prominent feature of the Koran, that point of excellence in which the partiality of its admirers has ever delighted to view it, is the sublime notion it general¬ ly impresses of the nature and attributes of God." If its author had really derived these just conceptions from the inspiration of that Being whom they "attempt to describe, they would not have been surrounded, as they now are on every side, with error and absurdity. But it might easily be proved, that whatever it justly defines of the Uiyine attributes, was borrowed from our Holy Scripture ; winch even from its first promulgation, but especially from the completion of the New Testament, has extended the views and enlightened the understandings of mankind; and thus furnished them with arms, which have too often, though ineffectually, been turned against itself by its un¬ generous enemies. In this instance particularly, the copy is far below the great original, both in the propriety of its images and the orce of its descriptions. Our Holy Scriptures are the only compositions that can enable the dim sight of mortality to penetrate into the invisible world, and to behold a glimpse 0 le hhvme perfections. Accordingly, when they would represent to us the happiness of heaven, they describe it, !! ! > ^,any thing minute and particular, but by something general and great,—something that, without descending o any determinate object, may at once by its beauty and I'nensity excite our wishes and elevate our affections. iov0^1 mv Pr°phetical and evangelical writings the tion nttend us in a future state are often men- hv'1 n 1 ar<^ent admiration, they are expressed rather y a usion than similitude, rather by indefinite and figu- A L C 391 rative terms than by any thing fixed and determinate. Alcoran | Eye hath not seen, nor ear heard, neither have entered II into the heart of man, the things which God hath pre- Alcoy. pared for them that love him.’ (1 Cor. ii. 9.) What a re-V^%^^ verence and astonishment does this passage excite in every hearer of taste and piety ! What energy, and at the same time what simplicity, in the expression! How su¬ blime, and at the same time how obscure, is the imagery! “ Different was the conduct of Mahomet in his descrip¬ tions of heaven and of paradise. Unassisted by the neces¬ sary influence of virtuous intentions and divine inspiration, he was neither desirous, nor indeed able, to exalt the minds of men to sublime conceptions or to rational expectations. By attempting to explain what is inconceivable, to describe what is ineffable, and to materialize what in itself is spirit¬ ual, he absurdly and impiously aimed to sensualize the purity of the Divine essence. " Thus he fabricated a sys¬ tem of incoherence, a religion of depravity, totally repug¬ nant indeed to the nature of that Being who, as he pretend¬ ed, was its object; but therefore more likely to accord with the appetites and conceptions of a corrupt and sensual age. “ That we may not appear to exalt our Scriptures thus far above the Koran by an unreasonable preference, we shall produce a part of the second chapter of the latter, which is deservedly admired by the Mahometans, who wear it engraved on their ornaments, and recite it in their prayers. ‘ God ! there is no God but he ; the living, the self-subsisting: neither slumber nor sleep seizeth on him: to him belongeth whatsoever is in heaven and on earth. Who is he that can intercede with him but through his good pleasure ? He knoweth that which is past, and that which is to come. His throne is extended over heaven and earth, and the preservation of both is to him no burden. He is the high, the mighty.’” {Sales Kor. ii. p. 30.4to edit.) Alcoran is also figuratively applied to certain other books full of impieties and impostures. In this sense we meet with the Alcoran of the Cordeliers, which has made a great noise; wherein St Francis is extravagantly mag¬ nified, and put on a level with Jesus Christ. The Alcoran of the Cordeliers is properly an extract of a very scarce book, entitled The Conformity of the Life of the seraphi* father St Francis with the Life of Christ, published in 1510, 4to ; since at Bologna in folio. Erasmus Albertus, being by the elector of Brandenburg appointed to visit a monas¬ tery of Franciscans, found this book; and being struck with the extreme folly and absurdity of it, collected a number of curiosities out of it, and published them under the title of the Alcoran of the Franciscans, with a preface by Martin Luther. ALCORANISTS, among Mahometans, those who ad¬ here strictly to the letter or text of the Alcoran, from an opinion of its ultimate sufficiency and perfection. The Persians are generally Alcoranists, as admitting the Alco¬ ran alone for their rule of faith. The. Turks, Tartars, Arabs, &c. besides the Alcoran, admit a multitude of traditions. The Alcoranists, among Mahometans, amount to much the same with the Textuaries among the Jews. The Alcoranists can find nothing excellent out of the Alcoran; are enemies of philosophers, metaphysicians, and scholas¬ tic writers. With them the Alcoran is every thing. ALCOVE, in Architecture, a recess, or part of a cham¬ ber separated by an estrade or partition of columns, and other corresponding ornaments, in which is placed a bed of state, and sometimes seats to entertain company. These alcoves are frequent in Spain, and the bed is raised two or three ascents, with a rail at the foot. ALCOY, a Spanish city on the sea-coast, in the pro¬ vince of Valencia. It has one parish church, three monas¬ teries, and 14,600 inhabitants. It has a manufactory for 392 A L C A L D Alcuinus. fine cloth, a soap-boiling house, and a very large manufac- tory for paper, which employs 48 mills. ALCUINUS, Flaccus, an ecclesiastic of the eighth century. He was born, it is supposed, in \ orkshire. He was educated, however, at York, under the direction of Archbishop Egbert, as we learn from his own letters, in which he frequently calls that great prelate his beloved master, and the clergy of York the companions of his youthful studies. As he survived Venerable Bede about 70 years, it is hardly possible that he could have received any part of his education under him, as some writers of literary histoiy have affirmed; and it is worthy of obser¬ vation, that he never calls that great man his master, though he speaks of him with the highest veneration. It is not well known to what preferments he had attained in the church before he left England, though some say he was abbot of Canterbury. The occasion of his leaving his native country was his being sent on an embassy by Offa, king of Mercia, to the emperor Charlemagne, who contract¬ ed so great an esteem and friendship for him, that he ear¬ nestly solicited, and at length prevailed upon him, to settle in his court, and become his preceptor in the sciences. Alcuinus accordingly instructed that great prince in rhe¬ toric, logic, mathematics, and divinity, which rendered him one of his greatest favourites. “ He was treated with so much kindness and familiarity,” says a contemporary writer, “ by the emperor, that the other courtiers called him, by way of eminence, the emperors delight!' Charle¬ magne employed his learned favourite to write several books against the heretical opinions of Felix, bishop of Urgel, in Catalonia, and to defend the orthodox faith against that heresiarch, in the council of Frankfort, a. d. 794; which he performed to the entire satisfaction of the emperor and council, and even to the conviction of Felix and his followers, who abandoned their errors. The em¬ peror consulted chiefly with Alcuinus on all things relat¬ ing to religion and learning, and by his advice did many great things for the advancement of both. An academy was established in the imperial palace, over which Alcuinus presided, and in which the princes and prime nobility were educated; and other academies were established in the chief towns of Italy and France, at his instigation, and under his inspection. “ France,” says one of our best writers of literary history, “ is indebted to Alcuinus for all the polite learning it boasted of in that and the following ages. The universities of Paris, Tours, Fulden, Soissons, and many others, owe to him their origin and increase, those of whom he was not the superior and founder being at least enlightened by his doctrine and example, and enriched by the benefits he procured for them from Charle¬ magne.” After Alcuinus had spent many years in the most intimate familiarity with the greatest prince of his age, he at length, with great difficulty, obtained leave to retire from court to his abbey of St Martin, at Tours. Here he kept up a constantcorrespondenceby letters with Charlemagne, from which it appears that both the empe¬ ror and his learned friend were animated with the most ardent love to learning and religion, and constantly em¬ ployed in contriving and executing the noblest designs for their advancement. He composed many treatises on a great variety of subjects, in a style much superior in purity and elegance to that of the generality of writers in the age in which he flourished. Charlemagne often solicited him, with all the warmth of a most affectionate friend, to return to court, and favour him with his company and advice; but he still excused himself, and nothing could draw him from his retirement in his abbey of St Martin in Tours, where he died a. d. 804. His works were collected and published by Andrew du Chesne, in one volume folio, urn speedily send you my treatise on Glory,” has the following woc?c*orro volo + inrr fine nAPair • ^ T-T<=» mPQnC- ?

ALcromuM Stagnum, in Ancient Geography, a lake in the territory of Corinth, whose depth was unfathomable, and in vain attempted to be discovered by Nero. Through this lake Bacchus is said to have descended to hell to bring back Semele. (Pausanias.) ALCYONIUS, Peter, a learned Italian, who flourished in the 16th century. He was well versed in the Greek and Latin tongues, and wrote some pieces of eloquence which met with great approbation. He was corrector of the press a considerable time for Aldus Manutius, and is entitled to a share in the praises given to the editions of that learned printer. He published a treatise concerning banishment, which contained so many fine passages inter¬ mixed with others quite the reverse, that it was thought he had tacked to something of his own, several fragments of a treatise of Cicero de Gloria; and that afterwards, in order to save himself from being detected in this theft, he burnt the manuscript of Cicero, the only one extant. Pau- lus Manutius, in his commentary upon these words of Cicero, Libram tihi celeriter mittam de gloria, “ I will passage relating to this affair: “ He means,” says he,1 two books on Glory, which were handed down to the age of our fathers; for Bernard Justinian, in the index of his books, mentions Cicero de Gloria. This treatise, however, when Bernard had left his whole library to a nunnery, could not be found, though sought after with great care; nobody doubted but Peter Alcyonius, who, being physi¬ cian to the nunnery, was intrusted with the library, had basely stolen it. And, truly, in his treatise of Banishment, some things are fount! interspersed here and there, which seem not to savour of Alcyonius, but of some higher au¬ thor.” The two orations he made after the taking of Rome, wherein he represented very strongly the injustice of Charles V. and the barbarity of his soldiers, were ex¬ cellent pieces. There is also an oration ascribed to him, on the knights who died at the siege of Rhodes. ALDBOROUGH, a market-town in the hundred of Plomsgate, of the county of Suffolk. It returns two mem¬ bers to parliament, who are nominally chosen by the own¬ ers of burgage houses, but in fact by the marquis of Hert¬ ford. It is a poor place, chiefly inhabited by fishermen. The markets are held on Wednesdays and Saturdays. It is distant 94 miles from London. The population has been as follows: in 1801, 804; in 1811,1060; and in 1921,1212. Aedborough, a small town in the wapentake ot Clare, in the West Riding of Yorkshire. It is on the river Ouse, and was formerly a Roman station, called Isunum Brigantium : near it are some remains of a druidical temple. It returns two members to parliament, who are nominally chosen by the occupiers of burgage tenures, but really by the owner of them, now the duke of Newcastle. The population has been as follows: in 1801, 445;>u 1811, 464 ; and in 1821, 484. It is 208 miles from London. ALDEA del Rio, a town of Spain, on the Guadalquivir, in the province of Cordova, with 3000 inhabitants.

ALDERMAN, in the British policy, a magistrate sub¬ ordinate to the lord-mayor of a city or town corporate. The number of these magistrates is not limited, but is more or less, according to the magnitude of the place. In London there are 26, each having one of the wards of the city committed to his care. This office is for life, so that when one of them dies or resigns, a wardmote is called, who return two persons, one of whom the lord-mayor and aldermen choose to supply the vacancy. All the aider- men are justices of the peace, by a charter of 15 Geo. II. The aldermen of London, &c. are exempted from serving inferior offices; nor shall they be put upon assizes, or serve on juries, so long as they continue to be aldermen. Alderman, among our Saxon ancestors, was a degree of nobility answering to earl or count at present. Alderman was also used in the time of King Edgar for a judge or justice. Thus we meet with the titles of aldermannus totius Anglice, aldermannus regis, comitatis, civitatis, burgi, castelli, hundredi sive wapentac/iii, et no- vmdecinwrum. According to Spelman, the aldermannus totim Anglice seems to have been the same officer who was afterwards styled capitalis justiciarius Anglice, or chief jus¬ tice of England; the aldermannus regis seems to have been an occasional magistrate, answering to our justice of assize; and the aldermannus comitalus, a magistrate who held a middle rank between what was afterwards called the earl and the sheriff: he sat at the trial of causes with the bishop; the latter proceeding according to ecclesiastical law, and the former declaring and expounding the com¬ mon law of the land. ALDERNEY, an island in the British channel, subject to the crown of Great Britain. It is about eight miles in compass, and is separated from Cape la Hogue, in Nor¬ mandy, by a narrow strait, called the Race of Alderney, which is a very dangerous passage in stormy weather, when the two currents meet; otherwise it is safe, and has depth of water for the largest ships. Through this strait the Irench fleet made their escape after their defeat at La Hogue in 1692. It is a healthful island, has but one church, is fruitful both in corn and pasture, and is remark¬ able for a fine breed of cows. The inhabitants live to¬ gether in a town of the same name. It has but one har¬ bour, called Crabby, which is at a good distance from the town, and is only fit for small vessels. To the west lie the range of rocks called the Caskets, so dangerous to mariners.

He is said to have been the son of Kenred, brother to Ina, king of the West ^axons; but in the opinion of William of Malmesbury, his ather was no more than a distant relation to the king. Having received the first part of his education in the school which one Maldulph, a learned Scot, had set up in p e P*ace where Malmesbury now stands, he travelled into lance and Italy for his improvement. At his return mine he studied some time under Adrian, abbot of St Augustin s, in Canterbury, the most learned professor of e sciences who had ever been in England. In these i ^rent seminaries he acquired a very uncommon stock o n°wledge, and became famous for his learning, not n y in England, but in foreign countries; whence several earned men sent him their writings for his perusal and rrection; particularly Prince Arcivil, a son of the king A L D 393 of Scotland, who wrote many pieces, which he sent to Aldhelm Aldhelm, “ entreating him to give them the last polish, II by rubbing off their Scotch rust.” He was the first English- Aldred. man who wrote in the Latin language, both in prose and'^’~v^v"/ verse, and composed a book for the instruction of his countrymen in the prosody of that language. Besides this, he wrote several other treatises on various subjects, some of which are lost, and others published by Martin Delrio and Canisius. Venerable Bede, who flourished in the end of this and the beginning of the next century, gives the following character of Aldhelm: “ He was a man of universal erudition, having an elegant style, and being wonderfully well acquainted with books, both on philosophical and religious subjects.” In fact, considering the cloud of ignorance by which he was surrounded, and the great difficulty of acquiring knowledge without prpper instruction, Aldhelm was a very extraordinary man. From one of his letters to Hedda, bishop of Winchester, concern¬ ing the nature of his studies whilst at Canterbury, he ap¬ pears to have been indefatigably determined to acquire every species of learning in his power. For a copy of this curious epistle, see Henry’s History, vol. ii. p. 320. King Alfred the Great declared that Aldhelm was the best of all the Saxon poets; and that a favourite song, which was universally sung in his time, near 200 years after its author’s death, was of his composition. When he was abbot of Malmesbury, having a fine voice, and great skill in music as well as poetry, and observing the backwardness of his barbarous countrymen to listen to grave instructions, he composed a number of little poems, which he sung to them after mass in the sweetest manner, by which they were gradually instructed and civilized. After this excellent person had governed the monastery of Malmesbury, of which he was the founder, about 30 years, he was made bishop of Shireburn, where he died A. d. 709.—He wrote, 1. De octo Vitiis principalibus. This treatise is extant in the Bibliotheca Patrum of Canisius. 2. iEnigmatum versus mille. This, with several others of his poems, was publish¬ ed by Martin Delrio at Mentz, 1601, 8vo. 3. A book addressed to a certain king of Northumberland, named Alfrid, on various subjects. 4. De Vita Monachorum. 5. De Laude Sanctorum. 6. De Arithmetica. 7. De Astrolo- gia. 8. A book against the mistake of the Britons con¬ cerning the celebration of Easter; printed by Sonius, 1576. 9. De Laude Virginitatis; manuscript, in Bennet College, Cambridge; published among Bede’s Opuscula. Besides many sonnets, epistles, and homilies in the Saxon lan¬ guage. ALDPORT, an ancient name for Manchester. ALDRED, abbot of Tavistock, was promoted to the bishopric of Worcester in the year 1046. He was so much in favour with King Edward the Confessor, and had so much power over his mind, that he obliged him to be reconciled with the worst of his enemies, particularly with Sweyn, son of Earl Godwin, who had revolted against him, and came with an army to invade the kingdom. Aldred also restored the union and friendship between King Edward and Griffith, king of Wales. He took after¬ wards a journey to Rome, and being returned into England, in the year 1054 he was sent ambassador to the emperor Henry II. He staid a whole year in Germany, and was very honourably entertained by Herman, archbishop of Cologne, from whom he learned many things relating to ecclesiastical discipline, which on his return he establish¬ ed in his own diocese. In the year 1058 he went to Je¬ rusalem, which no archbishop or bishop of England had ever done before him. Two years after, he returned to England; and Kinsius, archbishop of York, dying the 22d of December 1060, Aldred was elected in his stead on 3 D 394 A L D A L D Aldred. Christmas-day following, and was permitted to retain the see of Worcester with the archbishopric of York, as some of his predecessors had done. Aldred went soon after to Rome, in order to receive the pall from the pope : he was attended by Toston, earl of Northumberland, Giso, bishop of Wells, and Walter, bishop of Hereford. The pope received Toston very honourably, and made him sit by him in the synod which he held against the simonists. He granted to Giso and Walter their request, because they were tolerably well learned, and not accused of simony. But Aldred being by his answers found ignorant, and guilty of simony, the pope deprived him very severely of all his honours and dignities, so that he was obliged to return without the pall. On the way home he and his three fellow-travellers were attacked by some robbers, who took from them all that they had, though they did not offer to kill them. This obliged them to return to Rome; ■and the pope, either out of compassion, or by the threat- ■enings of the earl of Northumberland, gave Aldred the pallium; but he was obliged to resign his bishopric of Worcester. However, as the archbishopric of York had been almost entirely ruined by the many invasions of foreigners, King Edward gave the new archbishop leave to keep 12 villages or manors which belonged to the bishopric of Worcester. Edward the Confessor dying jn 1066, Aldred crowned Harold, his successor. He also crowned William the Conqueror, after he had made him take the following oath, viz. that he would protect the holy churches of God and their leaders ; that he would establish and observe righteous laws ; that he would en¬ tirely prohibit and suppress all rapines and unjust judg¬ ments. He was so much in favour with the Conqueror, that this prince looked upon him as a father ; and though imperious in regard to every body else, he yet submitted to obey this archbishop. John Brompton gives us an in¬ stance of the king’s submission, which at the same time shows the prelate’s haughtiness. It happened one day as the archbishop was at York, that the deputy-governor or lord-lieutenant, going out of the city with a great num¬ ber of people, met the archbishop’s servants, who came to town with several horses and carts loaded with provisions. The governor asked them to whom they belonged ; and they having answered they wrere Aldred’s servants, the governor ordered that all these provisions should be car¬ ried to the king’s storehouse. The archbishop sent im¬ mediately some of his clergy to the governor, command¬ ing him to deliver the provisions, and to make satisfaction to St Peter, and to him the saint's vicar, for the injury he had done them ; adding, that if he refused to comply, the archbishop would make use of his apostolic authority against him (intimating thereby that he would excom¬ municate him). The governor, offended at this proud message, used the persons whom the archbishop had sent him very ill, and returned an answer as haughty as the message was. Aldred thereupon went to London to make his complaint to the king; but in this very com¬ plaint he acted with his wonted insolence; for meeting the king in the church of St Peter at Westminster, he spoke to him in these words: “ Hearken, O William: when thou wast but a foreigner, and God, to punish the sins of this nation, permitted thee to become master of it, after having shed a great deal of blood, I consecrated thee, and put the crown upon thy head with blessings; but now, because thou hast deserved it, I pronounce a curse over thee, instead of a blessing, since thou art be¬ come the persecutor of God’s church, and of his ministers, and hast broken the promises and the oaths which thou madest to me before St Peter’s altar.” The king, ter¬ rified at this discourse, fell upon his knees, and, humbly begged the prelate to tell him by what crime he had de- A served so severe a sentence. The noblemen who were present were enraged against the archbishop, and loudly cried out he deserved death, or at least banishment, for^ having offered such an injury to his sovereign; and they pressed him with threatenings to raise the king from the ground. But the prelate, unmoved at all this, answered calmly, “ Good men, let him lie there, for he is not at Aldred’s but at St Peter’s feet; he must feel St Peter’s power, since he dared to injure his vicegerent.” Having thus reproved the nobles by his episcopal authority, he vouchsafed to take the king by the hand, and to tell him the ground of his complaint. The king humbly excused himself, by saying he had been ignorant of the whole matter; and begged of the noblemen to entreat the pre¬ late that he might take off the curse he had pronounced, and to change it into a blessing. Aldred was at last pre¬ vailed upon to favour the king thus far ; but not without the promise of several presents and favours, and only after the king had granted him to take such a revenge on the governor as he thought fit. Since that time (adds the historian) none of the noblemen ever dared to offer the least injury. It may be questioned which was more surprising here, whether the archbishop’s haughtiness, who dared to treat his sovereign after so unbecoming a manner, or the king’s stupidity, who suffered such inso¬ lence and audaciousness from a priest. The Danes having made an invasion in the north of England in the year 1068, under the conduct of Harold and Canute, the sons of King Sweyn, Aldred was so much afflicted at it, that he died of grief the 11th of September in that same year, having besought God that he might not see the desola¬ tion of his church and country. ALDRICH, Robert, bishop of Carlisle, was born at Burnham, in Buckinghamshire, about the year 1493, and educated at Eaton school, from whence, in 1507, he was elected scholar of King’s College, Cambridge, where he took his degree in arts, and was afterwards proctor of the university. In 1525 he was appointed master of Eaton school, then became fellow of that college, and finally provost. In 1529 he went to Oxford, where, being first incorporated bachelor of divinity, in the following year he proceeded doctor in that faculty. In 1531 he-was made archdeacon of Colchester, in 1534 canon of W ind¬ sor, and the same year registrary of the order of the Garter. He was consecrated bishop of Carlisle in the year 1537, and died at Horncastle in Lincolnshire in 1556. He wrote, 1. Epistola ad Gul. Hormanum, in Latin verse, printed in Herman’s Antibossicon, Lond. 1521, of which book Pitts erroneously makes Aldrich the author; 2. Epi- grammata varia; 3. Latin verses, and another epistle to Horman, prefixed to the Vulgaria Puerorum of that au¬ thor, Lond. 1519, 4to; 4. Answers to certain queries concerning the abuses of the mass, also about receiving the sacrament. Aldrich, Dr Henry, an eminent English divine and philosopher, born at London in 1647, was educated at Westminster school under the famous Dr Busby, and ad¬ mitted of Christ-church College, Oxford. He had a great share in the controversy with the Papists in the reign of James II.; and Bishop Burnet ranks him among those who examined all the points of Popery with a solidity of judg¬ ment, clearness of argument, depth of learning, and viva¬ city of writing, far beyond any who had before that time written in our language. He rendered himself so conspi¬ cuous, that at the Revolution, when Massey the Popis dean of Christ-church fled, his deanery was conferred on him. In this station he behaved in an exemplary man¬ ner, and that fabric owes much of its beauty to his mge- A L D Ak ch. nuity: it was Aldrich who designed the beautiful square called Peckwater Quadrangle, w'hich is esteemed an ex¬ cellent piece of architecture. In imitation of his prede¬ cessor Dr Fell, he published yearly a piece of some an¬ cient Greek author, as a present to the students of his house. He published a System of Logic, with some other pieces; and the revising of Clarendon’s History of the Re¬ bellion was intrusted to him and Bishop Sprat. Besides his preferments above mentioned, Dr Aldrich was also rector of Wem, in Shropshire. He was chosen prolocutor of the convocation in 1702. This worthy person died at Christ-church on the 14th of December 1710. As to his character, he was a most universal scholar, and had a taste for all sorts of learning, especially architecture. Sir John Hawkins has favoured the public with several parti¬ culars relative to Dr Aldrich’s skill in music; and on ac¬ count of the Doctor’s eminence in this respect, Sir John ha$ given his life, with his head prefixed. His abilities as a musician rank him,- we are told, among the greatest masters of the science. He composed many services for the church, which are well known; as are also his anthems, nearly to the number of 20. He adapted, with great skill and judgment, English words to many of the notes of Pales¬ trina, Carissimi, \ ictoria, and other Italian composers for the church, some of which are frequently sung in our ca¬ thedrals as anthems. By the happy talent which Dr Aldrich possessed, of naturalizing the compositions of the old Italian masters, and accommodating them to an Eng¬ lish ear, he increased the stores of our own church. Though the Doctor chiefly applied himself to the culti¬ vation of sacred music, yet being a man of humour, he could divert himself by producing pieces of a lighter kind. There are two catches of his, the one, Hark the bonny Christ-church Bells; the other, entitled A Smok¬ ing Catch, to be sung by four men smoking their pipes, which is not more difficult to sing than diverting to hear. His love of smoking was, it seems, so excessive, as to be an entertaining topic of discourse in the university. Such was Dr Aldrich’s regard for the advancement of music, and the honour of its professors, that he had formed a design of writing a history of the science ; and the mate- nals from which he proposed to compile it are yet extant in the library of his own college. It appears from these materials that he had marked down ev©ry thing which lie had met with concerning music and musicians, but that he had brought no part of them into any kind of ir^r A!drich’s some note as a Latin poet. In the Musa Anglicanm we find two elegant copies of verses by him; one on the accession of King William III., and the other on the death of the duke of Gloucester. Sir John Hawkins has preserved a humorous translation by him of the well-known English ballad, A soldier and a sailor, A tinker and a tailor, &c. 'The following epigram, entitled “ Causm Bibendi,” is likewise ascribed to Dr Aldrich A L D Indeed he is always spoken of as having been a man of Aldrov 395 Sx bene quid memini.

Having never been married, he appropriated ( his income to works of hospitality and beneficence, and encouraging learning to the utmost of his power, of which he was a most magnificent patron, as well as one of the greatest men in England, if considered as a Christian or a gentleman. He had always the interest of his college at heart, whereof he was an excellent governor. His mo¬ desty and humility prevented him from prefixing his name to the learned tracts which he published during his life. At his death he wished to be buried in the cathedral," without any memorial; which his thrifty nephew complied with, depositing him on the south side of Bishop Fell’s grave, December 22, eight days after his decease, which happened in the 63d or 64th year of his age. ALDROVANDUS, Ulysses, professor of philosophy and physic at Bologna, the place of his nativity. He was a most curious inquirer into natural history, and travelled into the most distant countries on purpose to inform him¬ self of their natural productions. Minerals, metals, plants, and animals, were the objects of his curious researches; but he applied himself chiefly to birds, and was at a great expense to have figures of them drawn from the life. Au- bert le Mire says, that he gave a certain painter, famous in that art, a yearly salary of 200 crowns, for 30 years and upwards; and that he employed at his own expense Lo¬ renzo Bennini and Cornelius Swintus, as well as the fa¬ mous engraver Christopher Coriolanus. These expenses ruined his fortune, and at length reduced him to the ut¬ most necessity; and it is said that he died blind in an hospital at Bologna, at a great age, in 1605. Mr Bayle observes, that antiquity does not furnish us with an in¬ stance of a design so extensive and so laborious as that of Aldrovandus, with regard to natural history; that Pliny has treated of more kinds of subjects, but only touches lightly on them, saying but a little upon any thing, where¬ as Aldrovandus has collected all he could meet with. His compilation, or that compiled upon his plan, consists of 13 volumes in folio, several of which were printed after his death. He himself published his Ornithology, or His¬ tory of Birds, in three folio volumes, in 1599; and his seven books of Insects, which make another volume of the same size. The volume of Serpents, three of Quadrupeds, one of Fishes, that of exanguious Animals, the History of Monsters, with the Supplement to that of Animals, the Treatise of Metals, and the Dendrology or History of Trees, were published at several times after the death of Aldrovandus, by the care of different persons; and Al¬ drovandus is the sole author only of the first six volumes of this work, the rest having been finished and compiled by others, upon the plan of Aldrovandus,—a most exten¬ sive plan, wherein he not only relates what he has read in naturalists, but remarks also what historians have written, legislators ordained, and poets feigned. Fie explains also the different uses which may be made of the things he treats of, in common life, in medicine, architecture, and other arts; in short, he speaks of morality, proverbs, de¬ vices, riddles, hieroglyphics, and many other things which relate to his subject. ALDSTON-MOOR, a market-town of the Ward of Leath, in the county of Cumberland. It is on the banks of the Tyne, in a picturesque district, abounding in mines of lead, whose produce is shipped from Hexham. It is 302 miles from London. The market is held on a Saturday.

ALE ALE ALE, a fermented liquor obtained from an infusion of malt, and differing from beer chiefly in having a less pro¬ portion of hops. This liquor, the natural substitute of wine in such countries as could not produce the grape, is said to have originally been made in Egypt, the first planted kingdom, on the dispersion from the East, that was supposed unable to produce grapes. And, as the Noachian colonies pierced further into the west, they found, or thought they found, the same defect, and sup¬ plied it in the same manner. Thus the natives of Spain, the inhabitants of France, and the aborigines of Britain, all used an infusion of barley for their ordinary liquor; and it was called by the various names of Calia and Ge- ria in the first country, Cerevisia in the second, and Cur- mi in the last; all literally importing only the strong water. “ All the several nations,” says Pliny, “ who inhabit the west of Europe, have a liquor with which they intoxicate themselves, made of corn and water. The manner of making this liquor is sometimes different in Gaul, Spain, and other countries, and is called by many various names ; but its nature and properties are everywhere the same. The people of Spain, in particular, brew the liquor so well that it will keep good a long time. So exquisite is the cunning of mankind in gratifying their vicious appetites, that they have thus invented a method to make water it¬ self intoxicate.” The method in which the ancient Bri¬ tons and other Celtic nations made their ale is thus de¬ scribed by Isidorus and Orosius : “ The grain is steeped in water and made to germinate, by which its spirits are excited and set at liberty; it is then dried and grinded ; after which it is infused in a certain quantity of water; which, being fermented, becomes a pleasant, warming, strengthening, and intoxicating liquor.” This ale was most commonly made of barley, but sometimes of wheat, oats, and millet. Anciently the Welsh and Scots had also two kinds of ale, called common ale and spiced ale ; and their value was thus ascertained by law: “ If a farmer hath no mead, he shall pay two casks of spiced ale, or four casks of common ale, for one cask of mead.” By this law, a cask of spiced ale, nine palms in height and eighteen palms in diameter, was valued at a sum of money equal in efficacy to L.7. I Os. of our present money; and a cask of common ale of the same dimensions at a sum equal to L.3. 15s. This is a sufficient proof that even common ale at that period was an article of luxury among the Welsh, which could only be obtained by the great and opulent. Wine seems to have been quite unknown even to the kings of Wales at that period, as it is not so much as once mentioned in their laws; though Giraldus Cambrensis, who flourished about a century after the Conquest, acquaints us that there was a vineyard in his time at Maenarper, near Pembroke, in South Wales. Ale wTas the favourite liquor of the Anglo-Saxons and Danes, as it had been of their ancestors the ancient Ger¬ mans. Before their conversion to Christianity, they believ¬ ed that drinking large and frequent draughts of ale was one of the chief felicities which those heroes enjoyed who were admitted into the hall of Odin. See Brewing, and Licensing. Medicated Ales, those wherein medicinal herbs havebeen infused or added during the fermentation. Gill Ale is that in which the dried leaves of gill or ground-ivy have been infused. It is esteemed abstersive and vulnerary, and consequently good in disorders of the breast and obstructions of the viscera.

ALEANDER, Jerome, cardinal and archbishop of Brindisi, was born in 1480, and distinguished himself at the beginning of the Reformation by the opposition he made to Luther ; for being sent into Germany as the pope’s nuncio in 1519, he acted, as occasion served, in the cha¬ racter of both ambassador and doctor, and declaimed three hours together against Luther’s doctrine before the diet at Worms, but could not prevent that celebrated re¬ former from being heard in that diet. He published seve¬ ral works, and died at Rome in 1542. Aleander, Jerome, nephew of the former, a learned man of the seventeenth century, born in the principality of Friuli, of the same family with the preceding. When he went to Rome, he was employed as secretary under Cardinal Octavius Bandini, and discharged this office with great honour for almost twenty years. He afterwards, by the persuasion of Urban VIII., who had a great esteem for him, became secretary to Cardinal Barberini, whom he accompanied to Rome when he went thither in the cha¬ racter of legate a latere, and in whose service he died in 1631. He was one of the first members of the Academy of Humorists, wrote a learned treatise in Italian on the device of the society, and displayed his genius on many different subjects. Barberini gave him a magnificent fu¬ neral at the academy of Humorists; the academists carried his corpse to the grave, and Caspar de Simeonibus, one of the members, made his funeral oration. ALECTO, one of the Furies, daughter of Acheron and Night, or, as others would have it, of Pluto and Proserpine. ALECTORIA, a stone said to be formed in the gall¬ bladder of old cocks, to which the ancients ascribed many fabulous virtues. This is otherwise called Alectorius lapis, sometimes Alectorolithos, in English the cock-stone. Ihe more modern naturalists hold the alectorius lapis to be ori¬ ginally swallowed down, not generated in, the stomach and gizzards of cocks and capons. It is known that manv of the fowl kind make a practice of swallowing pebbles, wdiich are supposed to be of service in the business of tri¬ turation and digestion. ALECTOROMANTIA, in Antiquity, a species of di¬ vination performed by means of a cock. This is otherwise called Alectryomancy, of which there appear to havebeen different species. But that most spoken of by authors was in the following manner: a circle was described on the ground, and divided into twenty-four equal portions; in each of these species was written one of the letters of1 alphabet, and on each of the letters was laid a grain o wheat; after which, a cock being turned loose jn ^ e circle, particular notice was taken of the grains picked up by the cock, because, the letters under them, being loim ed into a word, made the answer desired. It was t us, according to Zonaras, thatLibanius and Jamblicus sougi who should succeed the emperor Valens; and the cocj eating the grains answering to the spaces ©EGA, s^v^r‘^ whose names began with those letters, as Theo o us, Theodistes, Theodulus, &c. were put to death ; whic _ 1 not hinder, but promote Theodosius, to the successio_.

ALEGRETTE, a small town of Portugal, in Alentejo, on the confines of Port Alegre, on the river Caja, which falls into the Guadiana a little below Badajos, near the frontiers of Spanish Estremadura. It is a very pretty town, and finely situated ; seven miles south-east of Port Alegre, and thirty north of Elvas. Long. 5. 20. W. Lat. 39. 6. N. ALEUTS Campus, in Ancient Geography, a plain in Cilicia, on this side the river Pyramus, near the mountain Chimera, famous for Bellerophon’s wandering and perish¬ ing there, after being thrown off Pegasus; which is the reason of the appellation. ALEMANIA, or Allemania, in Ancient Geography, a name of Germany, but not known before the time of the Antonines, and then used only for a part. After the Marcomanni and their allies had removed from the Rhine, a rabble or collection of people from all parts of Gaul, as the term Alemanni denotes, prompted either by levity or poverty, occupied the lands, called Decumates by Tacitus, because they held them on a tithe ; now supposed to be the duchy of Wirtemberg. Such appear to have been the small beginnings of Alemania, which was in after-times greatly enlarged; but still it was considered as a distinct part; for Caracalla, who conquered the Alemanni, assum¬ ed the surname both of Alemannicus and Germanicus. ALEMBDAR, an officer in the court of the Grand Signior, who bears the green standard of Mahomet when the sultan appears in public on any solemn occasion. ALEMBERT, Jean le Rond d’, an eminent French philosopher, was born at Paris in 1717. He derived the name of Jean le Rond from that of the church near which, after his birth, he was exposed as a foundling. His father, informed of this circumstance, listened to the voice of nature and duty, took measures for the proper educa¬ tion of his child, and for his future subsistence in a state of ease and independence. He received his first education in the College of the Four Nations, among the Jansenists, where he gave early marks of capacity and genius. In the first year of his philosophical studies he composed a Commentary on the Epistle of St Paul to the Romans. The Jansenists con¬ sidered this production as an omen that portended to the party of Port-Royal a restoration to some part of their ancient splendour, and hoped to find one day in M. d’Alem¬ bert a second Pascal. To render this resemblance more complete, they engaged their rising pupil in the study of the mathematics; but they soon perceived that his grow¬ ing attachment to this science was likely to disappoint the hopes they had formed with respect to his future destina¬ tion : they therefore endeavoured to divert him from this hne; but their endeavours were fruitless. On his leaving college, he found himself alone and un¬ connected with the world; and sought an asylum in the house of his nurse. He comforted himself with the hope that his fortune, though not ample, would better the con¬ dition and subsistence of that family, which was the only one that he could consider as his own. Here, therefore, ic took up his residence, resolving to apply himself entire- y to the study of geometry; and here he lived, during the space of forty years, with the greatest simplicity, discover¬ ing the augmentation of his means only by increasing dis¬ plays of his beneficence, concealing his growing reputation nnd celebrity from these honest people, and making their ALE 397 plain and uncouth manners the subject of good-natured D’Alem- pleasantiy and philosophical observation. His good nurse bert. perceived his ardent activity, heard him mentioned asthe^-^^^^ writer of many books, but never took it into her head that he was a great man, and rather beheld him with a kind of compassion. “ You will never,” said she to him one day, he any thing hut a philosopher—and what is a philosopher ? —a fool, who toils and plagues himself during his life, that people may talk of him when he is no more.” As M. d’Alembert’s fortune did not far exceed the de¬ mands of necessity, his friends advised him to think of a profession that might enable him to augment it. He ac¬ cordingly turned his views to the law, and took his degrees in that line ; but soon abandoned this plan, and applied to the study of medicine. Geometry, however, was always drawing him back to his former pursuits ; and after many ineffectual efforts to resist its attractions, he renounced all views of a lucrative profession, and give himself over en¬ tirely to mathematics and poverty. In the year 1741 he was admitted member of the Aca¬ demy of Sciences; for which distinguished literary pro¬ motion, at such an early age, he had prepared the way by correcting the errors of a celebrated work,1 which was i The deemed classical in France in the line of geometry. He lyseDemon- afterwards set himself to examine, with deep attention and tde of assiduity, what must be the motion of a body which passes Beniau. from one fluid into another more dense, in a direction not perpendicular to the surface separating the two fluids. Every one knows the phenomenon which happens in this case, and which amuses children under the denomina¬ tion of Ducks and Drakes ; but M. d’Alembert was the first who explained it in a satisfactory and philosophical manner. Two years after his election to a place in the academy he published his treatise on Dynamics. The new prin¬ ciple developed in this treatise consisted in establishing equality, at each instant, between the changes that the motion of a body has undergone, and the forces or powers which have been employed to produce them; or, to ex¬ press the thing otherwise, in separating into two parts the action of the moving powers, and considering the one as producing alone the motion of the body in the second in¬ stant, and the other as employed to destroy that which it had in the first. So early as the year 1744, M. d’Alembert had applied this principle to the theory of the equilibrium, and the motion of fluids; and all the problems before solved by geometricians became in some measure its corollaries. The discovery of this new principle was followed by that of a new calculus, the first trials of which were published in a Discourse on the General Theory of the Winds, to which the prize-medal was adjudged by the academy of Berlin in the year 1746, and which was a new and brilliant addi¬ tion to the fame of M. d’Alembert. He availed himself of the favourable circumstance of the king of Prussia having just terminated a glorious campaign by an honourable peace, and in allusion to this, dedicated his work to that prince in the three following Latin verses:— Hcec ego de ventis, dum ventorum ocyor alls Palantes agit Austriacos Fredericus, et orM, Jnsignis lauro, rarntim prcctendit vlivce. Swifter than wind, while of the winds I write, The foes of conquering Frederick speed their flight; While laurel o’er the hero’s temple bends, To the tir’d world the olive branch he sends. This flattering dedication procured the philosopher a polite letter from Frederick, and a place among his literary friends. 398 ALE ALE D’Alem. In the year 1747 D’Alembert applied his new calculus bert. of Partial Differences to the problem of vibrating chords, the solution of which, as well as the theory of the oscil¬ lation of the air and the propagation of sound, had been given but incompletely by the geometricians who preceded him, and these were his masters or his rivals. In the year 1749 he furnished a method of applying his principles to the motion of any body of a given figure; and he solved the problem of the precession of the equi¬ noxes, determined its quantity, and explained the pheno¬ menon of the nutation of the terrestrial axis, discovered by Dr Bradley. In 1752 M. d’Alembert published a treatise on the Resistance of Fluids, to which he gave the modest title of an Essay, but which contains a multitude of original ideas and new observations. About the same time he published, in the Memoirs of the Academy of V>ev\m, Researches con¬ cerning the Integral Calculus, which is greatly indebted to him for the rapid progress it has made in the present cen¬ tury. While the studies of M. d’Alembert were confined to geometry, he was little known or celebrated in his native country. His connections were limited to a small society of select friends: he had never seen any man in high office except Messrs d’Argenson. Satisfied with an income which furnished him with the necessaries of life, he did not aspire after opulence or honours, nor had they been hitherto bestowed upon him, as it is easier to confer them on those who solicit them, than to look out for men who deserve them. His cheerful conversation, his smart and lively sallies, a happy knack at telling a story, a singular mixture of malice of speech with goodness of heart, and of delicacy of wit with simplicity of manners, rendered him a pleasing and interesting companion; and his com¬ pany, consequently, was much sought after in the fashion¬ able circles. His reputation at length made its way to the throne, and rendered him the object of royal atten¬ tion and beneficence. He received also a pension from government, which he owed to the friendship of Count d’Argenson. The tranquillity of M. d’Alembert was abated when his fame grew more extensive, and when it was known be¬ yond the circle of his friends, that a fine and enlightened taste for literature and philosophy accompanied his ma¬ thematical genius. Our author’s eulogist ascribes to envy, detraction, and to other motives equally ungenerous, all the disapprobation, opposition, and censure thatM. d’Alem¬ bert met with on account of the publication of the famous Encyclopedical Dictionary of Arts and Sciences, in con¬ junction with Diderot. None surely will refuse the well- deserved tribute of applause to the eminent displays of genius, judgment, and true literary taste, with which M. d’Alembert has enriched the great work now mentioned. Among others, the Preliminary Discourse which he has affixed to it, concerning the rise, progress, connections, and affinities of all the branches of human knowledge, is perhaps one of the first productions of which the philosophy of the present age can boast, and will be regarded as a striking specimen of just arrangement and sound criticism, and also as a model of accurate thinking and elegant wx-iting. Some time after this D’Alembert published his Philo¬ sophical, Historical, and Philological Miscellanies. These were followed by the Memoirs of Christina, Queen of Sweden, in which M. d’Alembert showed that he was ac¬ quainted with the natural rights of mankind, and was bold enough to assert them. His Essay on the LUercourse of Men of Letters with Persons high in Rank and Office wounded the former to the quick, as it exposed to the eyes of the public the ignominy of those servile chains which they feared to shake off or were proud to wear. A D’ \ lady of the court hearing one day the author accused of be having exaggerated the despotism of the great, and thev^s submission they require, answered slyly, If he had consulted me, I would have told him still more of the matter. M. d’Alembert gave very elegant specimens of his li¬ terary abilities in his translations of some select pieces of Tacitus. But these occupations did not divert him from his mathematical studies; for about the same time he en¬ riched the Encyclopedic with a multitude of excellent articles in that line, and composed his Researches on seve¬ ral important points of the System of the World, in which he carried to a higher degree of perfection the solution of the problem of the perturbations of the planets, that had several years before been presented to the Academy. In 1759 he published his Elements of Philosophy; a work extolled as remarkable for its precision and perspi- cuity; in which, however, are some tenets, relative both to metaphysics and moral science, that are far from being admissible. The resentment that was kindled, and the disputes that followed it, by the article Geneva, inserted in the Encyclopedic, are well known. M. d’Alembert did not leave this field of controversy with flying colours. Voltaire was an auxiliary in the contest; but as, in point of can¬ dour and decency, he had no reputation to lose, and as he weakened the blow of his enemies by throwing both them and the spectators into fits of laughter, the issue of the war gave him little uneasiness. It fell more heavily on D’Alembert, and exposed him, even at home, to much contradiction and opposition. It was on this occasion that the late king of Prussia of¬ fered him an honourable asylum at his court, and the place of president of his academy; and was not offended at his refusal of these distinctions, but cultivated an intimate friendship with him during the rest of his life. He had refused, some time before this, a proposal made by the empi*ess of Russia to intrust him with the education of the grand duke ; a proposal accompanied with all the flatter¬ ing offers that could tempt a man ambitious of titles or desirous of making an ample fortune; but the objects of his ambition were tranquillity and study. In the year 1765 he published his Dissertation on the Destruction of the Jesuits. This piece drew upon him a swarm of adversaries, who confirm the merit and credit of his work by their manner of attacking it. Besides the works already mentioned, he published nine volumes of memoirs and treatises under the title of Opus¬ cules, in which he has solved a multitude of problems re¬ lative to astronomy, mathematics, and natural philosophy; of which our panegyrist gives a particular account, more especially of those whiclx exhibit new subjects, or new methods of investigation. He published also Elements of Music, and rendered at length the system of Rameau intelligible; but he did not think the mathematical theory of the sonorous body suffi¬ cient to account for the rules of that art. He was always fond of music; which, on the one hand, is connected with the most subtile and learned researches of rational me¬ chanics ; while, on the other, its power over the senses and the soul exhibits to philosophers phenomena no less singular, and still more inexplicable. In the year 1772 he was chosen secretary to the French academy. He formed, soon after this preferment, the design of writing the lives of all the deceased acade¬ micians from 1700 to 1772; and in the space of three years he executed this design, by composing 70 eulogies.

Numerous coffee-houses are seen in all parts, some large and handsome, with a fountain in the middle, and a gallery for musicians. They are greatly frequented, and by persons of the highest rank. The bazars or market-places are long, covered, narrow streets, on each side of which is a great number of small shops, just sufficient to hold the tradesman and his goods, the buyer being obliged to stand without. Each separate branch of business has a particular bazar, which is locked up, as well as the streets, an hour and a half after sunset. This city is in itself one of the most agreeable in Syria, and is a trading and bustling place; and, owing to the great re¬ sort of Europeans, is considered by Mr Buckingham to be more than 100 years in advance of the other parts of Syria. On whatever side it is approached, its numerous minarets and domes present an agreeable prospect to the eye, fa¬ tigued with the continued sameness of the brown and parch¬ ed plains. In the centre is an artificial mountain surround¬ ed by a dry ditch, on which is a ruinous fortress. From hence we have a fine prospect of the whole city. To the north we discover the snowy mountains of Bailan, and on the west those which separate the Orontes from the sea, while to the south and east the eye can see as far as the Euphrates. In the time of Omar this castle stopped the progress of the Arabs for several months, and was at last taken by treachery; but at present it would not be able to resist the feeblest assault. Its slight wall, low and with¬ out a buttress, is in ruins; its little old towers are in no better condition ; and it has not four cannons fit for service, not excepting a culverine nine feet long, taken from the Persians at the siege of Bassora. Three hundred and fifty janizaries, who should form the garrison, are busy in their shops. Within the walls of the castle is a well, which, by means of a subterraneous communication, derives its water from a spring a league and a quarter distant. In the environs of the city we find a number of large square stones, on the top of which is a turban of stone, which are so many tombs. Aleppo may be considered the emporium of Armenia and Diarbekir. Four caravans annually pro¬ ceed through Natolia to Constantinople, and others arrive from Bagdad and Bassora with coffee from Mocha, and with muslins, shawls, and other goods from India. Cara¬ vans are sent also to Medina and Mecca, with which places a regular intercourse is maintained. The commerce with Europe is principally carried on from Scanderoon and Latakia, on the sea-coast. The chief commodities export¬ ed are, raw or spun cottons, clumsy linens fabricated in the villages, silk stuffs manufactured in the city, copper, bourres (coarse cloths) like those of Rouen, goats’ hair brought from Natolia, the gall-nuts of the Kourdistan, the merchandise of India, and pistachio-nuts of the growth of the neigh¬ bourhood. The articles supplied by Europe are cloths, Lyonese stuffs, and bonnets after the fashion of Tunis from France; merceries, indigo, tea, sugar, paper, soap, &c.; and a great quantity of coral ornaments. The coffee of America, though prohibited, is introduced, and serves to mix with that of Mocha. British, French, Dutch, and Italian houses are established at Aleppo, for the purposes of trade ; and most of the European states have consuls re¬ sident here. Aleppo is not exceeded in extent by any city in Turkey, except Constantinople and Cairo, and perhaps Smyrna. It is difficult to make any estimate of its popu¬ lation, but it is said to be increasing, and, according to the most authentic computation, does not probably contain less than 250,000 inhabitants. Of these, 30,000 are Chris¬ tians, who enjoy the most perfect toleration, and are treat¬ ed with more respect than in any town of the East. The air of Aleppo is dry and piercing, but at the A same time salubrious for all who are not troubled with'^r asthmatic complaints. The city, however, and the en¬ virons, are subject to a singular endemial disorder, which is called the ringworm or pimple of Aleppo: it is in fact a pimple which is at first inflammatory, and at length becomes an ulcer of the size of the nail. The usual du¬ ration of this ulcer is one year: it commonly fixes on the face, and leaves a scar, which disfigures almost all the in- habitants. No reason is assigned for this malady; but M. Volney suspects it proceeds from the quality of the water, as it is likewise frequent in the neighbouring vil¬ lages, in some parts of Diarbekir, and even in certain dis¬ tricts near Damascus, where the soil and the water have the same appearances. But the plague is a more destruc¬ tive malady, a visitation of which is anticipated by the inhabitants every ten years. Its ravages are most fatal, owing to the blind fatalism of the Turks, who cannot be persuaded to take any precautions against the progress of this dreadful disease. In the plague which immediately preceded the year 1797, about 60,000 inhabitants were swept off. Of the Christian inhabitants the greater num¬ ber are Greeks, next to them the Armenians, then the Syrians, and lastly the Maronites; each of wdiom has a church in the city called Judida; in which quarter, and the parts adjacent, most of them reside. The com¬ mon language is the vulgar Arabic, but the Turks of condition use the Turkish. Most of the Armenians can speak the Armenian, some few Syrians understand Syriac, and many of the Jews Hebrew ; but scarcely one of the Greeks understands a word of Greek. The people in gene¬ ral are of a middle stature, and tolerably well proportion¬ ed ; but they seem neither vigorous nor active. Both sexes are handsome when young ; but the women, as they come early to maturity, also fade very soon. The people of rank here are polite and affable, making allowances for that superiority which the Mahometan religion instructs its votaries to assume over all who hold a different faith. All the inhabitants of both sexes smoke tobacco to great excess; even the very servants have almost constantly a pipe in their mouth. Coaches or carriages are not used here ; therefore persons of quality ride on horseback in the city, with a number of servants walking before them, ac¬ cording to their rank. Ladies of the first distinction are even compelled to walk on foot in the city, or to any place at a moderate distance : in longer journeys they are carried by mules, in a kind of couch close covered up. There is a number of public baths in this city, which are used by people of all ranks, except those of the highest distinction, who commonly have baths and every other convenience in their own houses. The bath, being the only public rendezvous of the female sex, is a great scene of amuse¬ ment as well as of display : the bathers continue for hours conversing together, in their best apparel and most splendid ornaments. The gaiety of the place is still further enliven¬ ed by refreshments and music. Aleppo is of great anti¬ quity, and is supposed to occupy the site of the ancient Beroea. It was overwhelmed by the flood of Saracen in¬ vasion in 638, when it was taken from the emperor ^ra¬ dius. In 1260 it was taken possession of and wasted by the Tartars, and in 1401 by Tamerlane, who defeatei the Syrians, when it was given up to pillage. The ad¬ jacent country is fertile, and yields grain of all sorts, wit which the city is plentifully supplied. All the fruits o Europe, as well as those of the East, are cultivated in gar¬ dens. The pistachio-nut is regularly cultivated. Aleppo is 70 miles east of Scanderoon, on the sea-coast, north-east of Damascus. Long. 37. 4. E. Lat. 36.12. Aleppo, The Pacholic of, one of the five govern- pa ALE , ;s ments into which Syria is divided. It comprehends the country extending from the Euphrates to the Medi- Ak mi. terranean, between two lines, one drawn from Scanderoon ^ to Beer, along the mountains ; the other from Beles to the sea, by Mara and the bridge of Shoger. This space prin¬ cipally consists of two plains, that of Antioch to the w^est, and that of Aleppo to the east: the north and the sea- coast are occupied by considerably high mountains, known to the ancients by the names of Amanus and of Rhosus. In general, the soil of this government is fat and loamy. The lofty and vigorous plants which shoot up everywhere after the winter rains, prove its fertility, but its actual fruitfulness is but little. The greater part of the lands lies waste; scarcely can we trace any marks of cultivation in die environs of the towns and villages. Its principal pro¬ duce consists in wheat, barley, and cotton, which are found especially in the flat country. In the mountains they rather choose to cultivate the vine, mulberry, olive, and fig trees. The sides of the hills towards the sea-coast are appropriated to tobacco, and the territory of Aleppo to pistachios. The pasturage is not to be reckoned, because that is abandoned to the wandering hordes of the Turco¬ mans and Curds. The condition of the people depends entirely on the character of the pacha, who, when he is a tyrant, oppresses and plunders them without any restraint. From the mild administration of some of the late pachas, the people appear to be prosperous and happy. Mr Buckingham mentions, that the pacha who ruled in Aleppo at the time he visited this city acknowledged the influence of public opinion, and generally consulted the happiness of his subjects in the measures which he pursued. „ AkESIj Alexander, a celebrated divine of the con¬ fession of Augsburg, was born at Edinburgh the 23d of Apnl 150(h He soon made considerable progress in school divinity, and entered the lists very early against Luther, this being then the great controversy in fashion, and the grand field wherein all authors, young and old, used to display their abilities. Soon after, he had a share in the dispute which Patrick Hamilton maintained against me ecclesiastics, in favour of the new faith he had im- bibed at Marburg. He endeavoured to bring him back to the Catholic religion; but this he could not effect, and eren began himself to doubt about his own religion, being much affected by the discourse of this gentleman, and still more by the constancy he showed at the stake, where David neaton, archbishop of St Andrews, caused him to be burnt, beginning thus to waver, he was himself persecuted with so much violence, that he was obliged to retire into Ger¬ many, where he became at length a perfect convert to e 1 rotestant religion.

ALEUTIAN, Aleutic, or Aleutsky Islands, so called from the Russian word cs/ew#, signifying a bold rock, is the name given by the Russian discoverers to a chain of small islands situated in the Northern Pacific Ocean, and extending in an easterly direction from the peninsula of Kamtschatka, in Asiatic Russia, to the promontory of Alaska, in North America. According to the practice of the most recent Russian geographers, we have compre¬ hended the whole of this archipelago under one general name, although it has been sometimes divided into three several groups; those nearest to the eastern coast of Kamtschatcha being properly called Aleutian, the cen¬ tral group the Andreanofskie or Andrenovian, and those nearest to the American promontory the Fox Islands. The Russian geographers usually separate Behring’s and Copper Island, which are at the western extremity of this chain, from the other parts of it, included by them under the general name of Aleutian Islands j1 but as there seems no good reason for this exception, it certainly would be better to comprehend the whole under one ge¬ neral denomination.

Aleutian excited by the question, then much agitated, relative to Islands, the distance between the Asiatic and American conti- ^ nents ; the solution of which seemed to be facilitated by the recent conquest of Kamtschatka. A short time pre¬ vious to the death of that monarch, which took place in 1725, he drew up instructions, with his own hand, for the conduct of an expedition, which was to be intrusted to the command of an officer named Behring, who had al¬ ready made several voyages in the sea of Kamtschatka by order of the crown. In 1728 Behring set sail from the mouth of the Kamtschatka River, and coasted the eastern shores of Siberia, as far to the northward as lat. 67. 18., but made no discovery of the opposite continent. In 1729 he again set sail, for the purpose of prosecuting the same enterprise, but with no better success. A third voyage was undertaken by order of the empress Anna in 1741, and Behring was again selected as chief of the expedition, another vessel being intrusted to the com¬ mand of Tschirikoff. This enterprise proved more fortu¬ nate, and led the way to all the subsequent important discoveries of the Russians in those seas; although the immediate results of the voyage, upon the whole, were not deemed commensurate with the time and expense employed in fitting out the expedition. The principal object of the undertaking, however, appears to have been accomplished. Tschirikoff discovered the coast of Ame¬ rica in the 56th degree of latitude; and Behring, who was separated from his companion in a storm, saw it in lat. 58. 28. On his voyage back to Kamtschatka, Behring’s ship was driven on the island which now bears his name, where he soon afterwards died. The two uninhabited islands, Behring’s and Copper Island, now became known to the natives of Kamtschatka, who frequently resorted thither for the purpose of hunt¬ ing sea-otters, and other animals affording valuable furs^ with which they carried on a lucrative traffic. Some of the vessels which sailed upon these expeditions were driven by stormy weather to the south-east, by which means the group of Aleutian Islands came to be_ disco¬ vered. These islands seem to have been first visited in the year 1745, and continued to be resorted to for some time by private individuals, without attracting the atten¬ tion of the Russian government. In the above-mentioned year a vessel called the Eudokia was fitted out at the ex¬ pense of some private adventurers, and the command given to Michael Nevodtsikof, a native of Tobolsk. Hav¬ ing discovered three unknown islands, they ventured upon one of them, in order to kill sea-otters, of which they found a large quantity. These islands were un¬ doubtedly the nearest Aleutian Islands, and were found well inhabited. The Russians continued upon this island until the 14th September 1746, when, having incurred the enmity of the natives by their arbitrary and hostile proceed¬ ings, they put to sea with the view of looking out for some uninhabited islands. Being overtaken, however, by a vio¬ lent storm, they were driven about until the 30th October, when their vessel was wrecked upon the rocky shore of the island of Karaga, the inhabitants of which were of the Koriac tribe, and tributary to the Russian empire. From this period the zeal or avarice of individual adven¬ turers prompted them to undertake repeated voyages to the new-discovered islands, in some of which thejr penetrated as far eastward as the Fox Islands, where they collected a quantity of valuable skins; but, in consequence of their own rapacity and misconduct, they were frequently em¬ broiled in fatal quarrels with the natives. One of the Alei n most remarkable of these voyages was that of the St An- Isla^- drean and Natalia, fitted out by the merchant Andrean^ Tolstyk, which sailed from the mouth of the Kamtschatka River on the 27th September 1760, and on the 29th reached Behring’s Island. Having been driven on shore by a violent autumnal storm, they were here obliged to pass the winter; and after refitting, they put to sea again on the 24th June 1761. They passed by Copper Island, which lies about 150 versts from the former, and steered south-east towards the Aleutian Isles, which they did not reach before the 6th August. From thence they pro¬ ceeded on the 19th in quest of some more distant islands, for the purpose of exacting tribute, steering their course north-east and north-east by east, and were driven by a gale of wind towards an island, where, on the 30th Au¬ gust, they anchored in a safe bay. This island they called Ayagh or Kayaka, and another, which lay at the distance of about 20 versts, Kanaga. The Russians persuaded the inhabitants of these islands to become tributary to the empress, to which they made no great objection. Four other islands were discovered in the neighbourhood, and the crew remained here in great tranquillity until the year 1764, but met with no great success in their hunting excursions. This group of islands, which lies somewhat to the north-west of the Fox Islands, was denominated, in honour of the vessel which made the discovery, the Andreanofskie or Andrenovian Isles. From the year 1758 to 1760 several vessels visited the Fox Islands, and obtained considerable cargoes of sea- otter and fox skins. But the crews appear to have be¬ haved with the most shameful inhumanity towards the natives; and little information was derived from these voyages, except a few particulars which transpired during the course of a judicial investigation into their conduct. In 1762 four vessels sailed for the Fox Islands, of which only one returned safe to Kamtschatka. The first was the Zacharias and Elizabeth, fitted out by Kulkof and Company of Vologda, under the command of Drusimn, with a crew of thirty-four Russians and three Kamtschadals. This vessel touched at the Aleutian Islands, and in the beginning of September 1763 arrived at Umnak, one of the most considerable of the Fox Islands. On the 22d September they proceeded to Unalashka, where the ves¬ sel was brought into a safe harbour. Here the crew formed themselves into hunting parties, but were soon afterwards attacked separately by the natives, and cut off, with the exception of four individuals, who, after de¬ fending themselves with astonishing courage and pidity, and suffering incredible hardships, succeeded in making their escape from the island in a baidar, their own vessel having been destroyed by the savages. One ot these four died during the home voyage; but the other three returned safe to Kamtschatka, and gave an accoun of their adventures. . The second vessel which sailed from Kamtschatka i 1762 was the Trinity, fitted out by the trading company of Nikiphor Trapesnikof, a merchant ot Irkutsk, under e command of Ivan Korovin, and manned with thirty-wg Russians and six Kamtschadals. In the month °t k c ° they cast anchor before the south side of Behring s s an > where they resolved to winter, on account of the late sea¬ son of the year. On the first of August 17®3 sailed from Behring’s Island, in company with ^ Medvedef, who commanded a vessel1 fitted out byJ 1 This was the fourth vessel which sailed in 1762 ; but, as the whole crew were massacred by the natives, we have no distinct ac count of the voyage. i ALEUTIAN ISLANDS. 403 tian Protassof, merchant of Tiumen. On the 15th the former Is ids. vessel made Unalashka, and Medvedef reached Umnak. having reconnoitred the coast, and received host¬ ages from the Toigons or Chiefs, Korovin sent out several hunting parties; but the natives soon began to exhibit hostile intentions, and three Kamtschadals belonging to ways suspicious, Glottof did not think it prudent to pro¬ long his stay; and accordingly, having taken on board all the peltry and stores, he left Kadyak on the 24th May' 1764, and sailed for Umnak, where he arrived on the 3d July. He remained here two years, sending out hunting parties through the islands of Umnak and Unalashka, and Aleutian Islands.

U „ ’ _ _ 1 r* • t t that vessel, and the massacre of the crew. On the 10th December the savages assembled in large bodies, and invested the hut which the Russians had constructed, and continually annoyed them with their darts. Korovin find¬ ing himself thus harassed by the natives, ordered the hut to be destroyed, and retired to his vessel, which was re¬ moved to the distance of a hundred yards from the beach, where they lay at anchor from the 5th March to the 26th April 1764. Here the natives attempted to surprise the vessel; but Korovin, having been warned of their ap¬ proach, compelled them to retreat. On the 26th April Korovin sailed from Unalashka, and, after being driven about by contrary winds, the vessel was at length strand¬ ed on the 28th, in a bay of the island of Umnak. Having got on shore, the crew attempted to secure themselves between their baidar and some empty barrels, with the sails spread over them in the form of a tent. Next morn¬ ing before the break of day they were surprised by a large body of the natives, who attacked them with their darts, and wounded every one of the crew. Korovin, however, sallied out, in company with four Russians, and put the savages to flight, although he and his party were so se¬ verely wounded, that they had scarcely sufficient strength to return to the tent. During the night the vessel was dashed to pieces by the storm. On the 30th of April they were again attacked by the natives, who, however, were soon put to flight by the fire of the Russians. On the 21st of July, Korovin, with the remainder of his crew, which was now reduced to the number of twelve persons, including six Kamtschadals, put to sea in a baidar; and, having landed upon another part of the same island, they discovered the remains of a vessel which had been burnt, and at a small distance, a deserted Russian dwelling, con¬ taining twenty dead bodies in their clothes ; among which they recognised several of those individuals who had sail¬ ed in Protassof’s vessel, and distinguished, among the rest, the commander Medvedef. Korovin afterwards join¬ ed Glottof’s vessel (of whose proceedings we shall imme¬ diately give some account), which he quitted in the month of April 1765, and went over, with five other Rus¬ sians, to Soloviof, with whom he returned the following year to Kamtschatka. The third voyage from Kamtschatka in 1762, and the most fortunate and most remarkable of the whole, was that of the Andrean and Natalia, which was fitted out by Terenty Tsebaeffskoi and Company, under the command of Stephen Glottof, an experienced and skil¬ ful seaman of Yarensk. This vessel sailed on the 1st October, with a crew of thirty-eight Russians and eight Kamtschadals. Having wintered at Copper Island, they set sail from thence on the 26th July 1763, and steered lor the Fox Islands. Inconsequence of storms and contrary winds, they were thirty days on the voyage to Umnak, ijhere they arrived on the 24th August, and without dropping anchor, sailed farther in quest of new islands, of which they passed eight contiguous to each other, and separated by straits from 20 to 100 versts broad. Glottof, however, did not land until he reached the most eastward of these islands, called by the inhabitants Kadyak. Here and in the neighbouring islands they passed the winter, and collected a considerable quantity of furs ; but as the conduct of the natives, at first decidedly hostile, was al- 1766, In the month of August he arrived safe in Kamt¬ schatka River with a rich cargo. Soloviof, to whose voyage we have already alluded, sailed from Kamtschatka on the 25th of August 1764, in a ship called the Holy Apostles Peter and Paul, fitted out by Jacob Ulednikof and Company, merchants of Irkutsk. This vessel reached Unalashka on the 17th September, where Soloviof passed two winters; and having succeed¬ ed, notwithstanding the continual hostility of the natives, in collecting a considerable cargo of peltry, he returned to Kamtschatka in the month of July 1766. Having thus traced an outline of the gradual progress of early discovery in this archipelago, it seems unneces¬ sary to proceed with an enumeration of the subsequent voyages performed by private individuals. These were undertaken merely for commercial purposes: the accounts brought home by the adventurers were generally imperfect and incorrect, and rather tended to excite than to gratify the curiosity of those who might be desirous of obtaining more accurate and more ample information. We shall therefore now turn to the conduct of those expeditions which were fitted out by the state for the express purpose of discovery. In the year 1768 Captain Krenitzin and Lieutenant Levashef sailed from the mouth of the Kamtschatka River by order of the empress Catharine, to examine the chain of Aleutian Islands. This commission they accordingly exe¬ cuted very carefully, having surveyed the whole of this archipelago, from Behring’s Island to the promontory of Al¬ aska; and, after spending the winter among the Fox Islands, they returned to Kamtschatka in the autumn of 1769. But our great navigator Captain Cook communicated more accurate scientific information respecting these islands, as well as the coasts of the two continents, than all the previous voyages of the Russian discoverers had afforded. During his third and last voyage, in the year 1778, he surveyed the eastern portion of this archipelago, accurately determined the positions of some of the most remarkable islands, and corrected many errors of former navigators. In the year 1785 a fresh expedition was set on foot by the Russian government, the command of which was in¬ trusted to Captain Billings, an English naval officer in the Russian service, who had accompanied Captain Cook in his last celebrated voyage to the Pacific Ocean. This ex¬ pedition appears to have been suggested by Mr Coxe, who was at that time at St Petersburg, and whose Account of the Russian Discoveries between Asia and America had al¬ ready attracted the attention of the Russian government. During this voyage, which was not completed until the year 1796, Captains Billings and Sarytschef explored the whole chain of the Aleutian Islands, particularly that part of it which had been visited by Captain Cook, and some parts of the adjacent western coast of America. Ample details of the conduct of this expedition have been pub¬ lished in the narratives of Martin Sauer, who officiated as secretary to Captain Billings, and of Admiral Sarytschef. Some years after the termination of the expedition un¬ der Captain Billings, the attention of the Russian Ameri¬ can Company was turned towards the best means of sup¬ plying their settlements on the north-west coast of Ame- 404 ALEUTIAN ISLANDS. Aleutian rica with provisions and stores of all kinds; and it was Islands, resolved to try whether the conveyance by sea would not answer the purpose better than the long and tedious journey by land to Ochotsk. With the view of ascertain¬ ing the practicability of the project, Captain Krusenstern, an experienced Russian naval officer, who had served for a long period in the British navy, suggested the plan of an expedition from Cronstadt, round Cape Horn, to the Aleutian Islands and the north-west coast of America. This plan was approved of by Count Romanzof, the mi¬ nister of commerce, and Admiral Mordwinof, minister of the marine, and obtained the sanction of his Imperial Majesty. Two vessels, called by the Russians the Na- deshda and the Neva, were accordingly purchased in Lon¬ don for the voyage. The command of the expedition was intrusted to Captain Krusenstern, the original author of the plan, and Captain Lisiansky was appointed to the Neva. These two vessels accordingly sailed in company from Cronstadt, in the month of August 1803, and, after a short stay at Falmouth, proceeded to the Brazils, from whence they sailed round Cape Horn to the Sandwich Islands. Here they separated, the Nadeshda being or¬ dered on a distinct mission to Japan and China, while . Captain Lisiansky, in the Neva, proceeded to Kadyak and the American settlements. Of this voyage very full and interesting accounts have been lately published by Cap¬ tains Krusenstern and Lisiansky, and by Dr Langsdorff, who accompanied the expedition in the quality of physi¬ cian. Enumera- From the ample sources of information to which we have tion and alluded in the foregoing narrative, we shall now proceed descrip- t0 exhibit an enumeration and general description of the Aleutian16 ^s^an(ls composing this singular chain, which appears to be Islands/ a prolongation of either continent. We shall begin with the more westerly part of the chain, consisting of those islands which lie nearest to Kamtschatka, and proceed eastwards to the American promontory. The first is Commodore or Behring’s Island, situate, according to Cook’s reckoning, in 55° of latitude and 6° of longitude from the harbour of Petropaulowska in the bay of Awat- ska. It is from 70 to 80 versts long, and stretches from north-west to south-east. Ten leagues from the south-east point of this island, in the direction of east by south, or east-south-east, lies Mednoi Ostroff, or Copper Island, so called from large masses of native copper being found upon the beach. To the south-east of Copper Island lie three small islands, Attak or Attoo, Semitshi, and Agattoo, called by the Russians Plishnie Ostrova, or the nearest Aleutian Islands. Of these Attak is the largest; it is nearly of the same shape as Behring’s Island, but rather more extensive, stretching from west to east to the length of 18 leagues. These islands are situated between 54° and 55° of north latitude. Attak has two harbours, one of which lies on the southern coast. From the eastern extremity of the Aleutian Islands properly so called, an¬ other group runs south-eastward, continuing the chain as far as the western extremity of the Fox Islands. These are called the Andreanofskie Islands; but we have less accurate information respecting this central part of the chain than regarding the eastern and western groups. They are said to lie w ithin the 52d and 54th degrees of north latitude, to be of inconsiderable extent or import¬ ance, and therefore seldom visited by recent navigators. The most remarkable are, Takavangha, which has in its centre, near the northern coast, a burning mountain; Kanaghi or Kanaga, likewise with a high smoking moun¬ tain ; Ayag, which has a number of good bays and anchor¬ ing-places ; and Tshetchina, on which a high white moun¬ tain overtops the rest, which apparently is an extinct A1 volcano, as there are still hot springs on this island. At- Is shak or Atchka, and Amlac, are also usually reckoned^ among the number of the Andrenovian Isles. The former greatly resembles Copper Island, and is provided with a commodious harbour. By far the most important and best explored portion of this archipelago is the most easterly group, called by the Russians Lyssie Ostrova, or the Fox Islands. Of these islands the most considerable are, Umnak, Unalashka or Oonalashka, and Unimak, the last of which is separated by a narrow strait from the promontory of Alaska. Beyond these, to the north-east, lies the large island of Kadyak or Kodiak, which is generally included among the group called Schumagin’s Islands. The whole of the islands composing this chain are bare and mountainous; their coasts are rocky and surrounded by breakers, which renders the navigation of those seas exceedingly dangerous. The land rises immediately from the coasts to steep bald mountains, gradually ascending higher behind each other, and assuming the appearance of chains of mountains, with a direction lengthwise of the island. Springs take their rise at the bottom of the moun¬ tains, and either flow in broad and rapid streams into the neighbouring sea, or, collecting in the rocky vales and glens, form ample lakes, which send off their superfluous waters by natural canals into the adjacent bays. These islands bear evident marks of volcanic formation, and se¬ veral of them have still active volcanoes, which continually emit smoke, and sometimes flames. No traces of metals have been discovered on these islands, but carneoles and sardonyxes are brought from thence. Their soil is said to be similar to that of Kamtschatka, and affords the same kinds of edible wild berries and roots, excepting some few vegetables which seem to be of foreign origin. No wood of any considerable growth has been perceived upon any of these islands, except a very small quantity on Unalash¬ ka. The land animals are bears, wolves, river-otters, river-beavers, and ermines. The sea-otter, so valuable on account of its skin, is frequently caught; but the number of these animals, it is believed, is much diminished of late. On the Fox Islands they have a great variety of foxes, black, grey, red, and brown. The sea abounds with all sorts of seals, dolphins, and whales; sea-lions and porpoises are rare, and sea-cov/s not at all to be seen. Salmon are caught in great abundance and variety, and halibut of an immense size are frequently taken. The winter upon these islands is tolerably mild, but the summer is equally short and unpleasant. The inhabitants are pretty numerous, and tributary to Russia, from whence vessels are sent out, and establishments formed upon these islands, on account of the very profitable chace of sea-otters and foxes. Unalashka, one of the largest of the Fox Islands, was Ka visited by Captain Cook during his last voyage, and seems to merit particular notice. This island stretches from north-east to south-west, and is from 70 to 80 versts m length, but of very unequal breadth. On the north ant. north-east sides there are many bays and creeks, in some of which are very secure harbours for vessels. A part o the south-west shore consists of very high, steep, inac¬ cessible cliffs, and another part has remained hitheito wholly unexplored. The whole island consists of a mas> of rocks, covered only with a very thin coat of earth; the hills are of very unequal height, and are intersected b) irregular valleys, the soil of which is commonly argilla¬ ceous, or an earth which appears washed down from t e hills. In the lower valleys there is great abundance o grass, which would furnish very good food for catt e, an (is. of bka. . ALEUTIAN ISLANDS. tivf A itian indeed, Captain Cook was of opinion that cattle might i nds. subsist at Unalashka all the year round, without being ^'''^housed; and the soil, in many places, appeared capable of producing grain, roots, and vegetables. But the Russian traders and the natives seem satisfied with what nature brings forth. No wood grows on this and the neighbour- big islands; only low bushes, and shrubs of dwarf birch, willow, and alder. For all the timber used for the purposes of building, &c. they are indebted to the sea, which wafts it to their shores from the adjacent continent of America. The inhabitants are rather low in stature, but plump and well-shaped, with short necks, swarthy chubby faces, black eyes, small beards, and long, straight, black hair, which the men wear loose behind and cut before, but the women Ch: cter tie up in a bunch. With regard to their character, Cap- irft na- tain Cook describes them as, to all appearance, the most inoffensive people he ever met with, and perfect patterns of honesty. But according to the accounts of the first discoverers, this does not seem to have been their original disposition; and recent travellers have observed, that al¬ though generally kind-hearted and peaceable, yet, when roused to anger, they become exceedingly malevolent, and indifferent to all danger, even to death itself. The clothing of the men and women is nearly the same, and consists of a sort of frock or shirt, called parka, fastened round the neck with a broad stiff collar, and descending below the knee. These garments are made of the skins of seals, prepared in a manner peculiar to themselves, and sewed together very ingeniously. Though simple in their form, they are ornamented in a variety of ways,—with glass beads, beaks of sea-parrots, long white goats’ hair brought from Siberia, or small red feathers. Over the frock the men sometimes wear a kamleika or rain-gar¬ ment. This is made of gut, which is water-proof, and has a hood to it, which draws over the head, and is tied under the chin. When on shore, the men wear boots made of seal-skin; and they all have a kind of oval-snouted cap, made of wood, with a rim to admit the head. These caps are dyed with green and other colours, and are very fancifully ornamented with ivory figures, carved from the teeth of the sea-cow, with glass or amber beads, and with the bristles from the beard of the sea-lion. They make use of no paint: tatooing was for¬ merly very much in use among them, particularly among the women; but their intercourse with the Russians has rather brought this practice into disrepute. Both men and women, particularly the latter, bore the under lip, and insert pieces of bone or other ornaments; but this practice has also decreased of late. The women, for the most part, go barefooted: they wear bracelets of glass beads just above the wrists and ankle-joints, and are very fond of rings upon their fingers. The principal food of these islanders consists of fish, sea-animals, birds, roots, and bemes. They dry large quantities of fish in summer, W Ju .y % UP ^ small huts for winter use ; and roots and then suffered himself to be lulled into idleness and effeminacy. Awakened suddenly from his lethargy by the noise of the conquests of Cosroes, that scourge of the East, he put himself at the head of his armies, distinguish¬ ed himself as a great captain from his very first campaign; ALEXANDRIA. iii®- laid waste Persia for seven years, and returned to his ca- ci- pital covered with laurels: he then became a theologian the throne, lost all his energy, and amused himself the rest of his life with disputing upon monotheism, whilst the Arabs were robbing him of the finest provinces of the empire. Deaf to the cries of the unfortunate inhabitants of Alexandria, as he had been to those of the people of Jerusalem, who defended themselves for two years, he left them a sacrifice to the rising fortune of the indefatigable Amrou. All their intrepid youth perished with their arms in their hands. The victor, astonished at his conquest, wrote to the ca¬ liph, “ I have taken the city of the west. It is of an im¬ mense extent. I cannot describe to you how many won¬ ders it contains. There are 4000 palaces, 4000 baths, that they should be called to an account by the Greeks for their former perfidious conduct, had petitioned Oth- man to send him again into Egypt.—Upon Amrou’s arri-' val, therefore, at Alexandria, the Copts or natives, with the traitor Al-Mokawkas (who had formerly betrayed to Amrou the fortress of Mesr) at their head, not only joined him, but supplied him with all kinds of provisions, excit¬ ing him to attack the Greeks without delay. This he did; and, after a most obstinate dispute, which lasted several days, drove them into the town, where, for some time, they defended themselves with great bravery, and repel¬ led the utmost efforts of the besiegers. This so exaspe¬ rated Amrou, that he swore, if God enabled him to conquer the Greeks, he would throw down the walls of the city, and make it as easy of access as the house of a 12,000 dealers in fresh oil, 12,000 gardeners, 40,000 Jews* prostitute. Nor did he fail to execute his threat; for, 411 Alexan¬ dria. who pay tribute, 400 theatres or places of amusement.” At this time, according to the Arabian historians, Alex¬ andria consisted of three cities, viz. Menna, or the port, which included Pharos and the neighbouring parts; Alexandria, properly so called, where the modern Scan- deria now stands ; and Nekita, probably the Necropolis of Josephus and Strabo. At that time John, surnamed the Grammarian, a fa¬ mous Peripatetic philosopher, being in the city, and in high favour with Amrou Ebn al Aas, the Saracen general, begged of him the royal library. Amrou replied that it was not in his power to grant such a request; but that he would write to the caliph on that head, since, without knowing his pleasure, he dared not to dispose of a single book. He accordingly wrote to Omar, who was then ca¬ liph, acquainting him with the request of his friend ; to which the ignorant tyrant replied, That if those books contained the same doctrine with the Koran, they could be of no use, since the Koran contained all necessary truths; but if they contained any thing contrary to that book, they ought not to be suffered ; and, therefore, what¬ ever their contents were, he ordered them to be destroyed. Pursuant to this order, they were distributed among the public baths, where, for the space of six months, they served to supply the fires of those places, of which there was an incredible number in Alexandria. After the city was taken, Amrou thought proper to pursue the Greeks who had fled farther up the country; and therefore marched out of Alexandria, leaving but a very slender garrison in the place. The Greeks, who had before fled on board their ships, being apprized of this, re¬ turned on a sudden, surprised the town, and put all the Arabs they found therein to the sword; but Amrou, re¬ ceiving advice of what had happened, suddenly returned, and drove them out of it with great slaughter: after which the Greeks were so intimidated, that he had no¬ thing further to fear from them.—A few years after, how¬ ever, Amrou being deprived of his government by the ca¬ liph Othman, the Egyptians were so much displeased with his dismission, that they inclined to a revolt; and Constantine, the Greek emperor, having received intelli¬ gence of their disaffection, began to meditate the reduc¬ tion of Alexandria. For this purpose he sent one Ma¬ nuel, a eunuch, and his general, with a powerful army, to retake that place; which, by the assistance of the Creeks in the city, who kept a secret correspondence with the imperial forces while at sea, and joined them as soon as they had made a descent, he effected, without any con¬ siderable effusion of Christian blood. The caliph, now perceiving his mistake, immediately restored Amrou to his former dignit}\ This step was very agreeable to the natives, who, having had experience of the military skill and bravery of this renowned general, and apprehending having taken the town by storm, he quite dismantled it, entirely demolishing the walls and fortifications. The lives of the citizens, however, were spared, at least as far as lay in the general’s power; but many of them were put to the sword by the soldiers on their first entrance. In one quarter particularly, Amrou found them butchering the Alexandrians with unrelenting barbarity; to which, however, by his seasonable interposition, he put a stop, and on that spot erected a mosque, which he called the mosque of mercy. From this time Alexandria never recovered its former splendour. It continued under the dominion of the ca¬ liphs till the year 924, when it was taken by the Magre- bians, two years after its great church had been destroyed by fire. This church was called by the Arabs Al Kaisa- ria, or Caesarea, and had formerly been a pagan temple, erected in honour of Saturn by the famous Queen Cleo¬ patra. The city was soon after abandoned by the Magrebians; but in 928 they again made themselves masters of it. Their fleet being afterwards defeated by that belonging to the caliph, Abul Kasem the Magrebian general retired from Alexandria, leaving there only a garrison of 300 men; of which Thmaal, the caliph’s admiral, being ap¬ prized, he in a few days appeared before the town, and carried off the remainder of the inhabitants to an island of the Nile called Abukair. This was done to prevent Abul Kasem from meeting with any entertainment at Alexandria, in case he should think proper to return. According to Eutychius, above 200,000 of the miserable inhabitants perished this year. What contributed to raise Alexandria to the extra¬ ordinary height of splendour it enjoyed for a long time, was its being the centre of commerce between the eastern and western parts of the world. It was with the view of becoming master of this lucrative trade that Alexander built this city, after having extirpated the Tyrians, who formerly engrossed all the East India traffic. Of the im¬ mense riches which that trade afforded, we may form an idea, from considering that the Romans accounted it a point of policy to oppress the Egyptians, especially the Alexandrians ; and after the defeat of Zenobia, there was a single merchant of Alexandria, who, it is said, under¬ took to raise and pay an army out of the profits of his trade. The Greek emperors drew enormous tributes from Egypt, and yet the caliphs found their subjects in such good circumstances that they were able to screw up their revenues to 300,000,000 of.crowns. Though the revolutions which happened in the govern¬ ment of Egypt after it fell into the hands of the Maho¬ metans frequently affected this city to a very great de¬ gree, yet still the excellence of its port, and the innu¬ merable conveniences resulting from the East India trade, 412 ALEXANDRIA. Alexan- to whomsoever were masters of Egypt, preserved it from dria. total destruction, even when in the hands of the most bar- ^v^barous nations. Thus, in the 13th century, when the European nations began to acquire a taste for the ele¬ gancies of life, the old mart of Alexandria began to re¬ vive ; and the port, though far from recovering its former magnificence, grew once more famous by becoming the centre of commerce: but having fallen under the domi¬ nion of the Turks, and the passage round the Cape of Good Hope being discovered by the Portuguese in 1499, a fatal blow was given to the Alexandrian commerce, and the city thenceforward declined from its ancient greatness. Alexandria, Modern. It now presents little more than half-ruined houses and rubbish, with a few frag¬ ments of those magnificent edifices by which it was once adorned. The estimates of its population have fluc¬ tuated remarkably, varying between 5000 and 20,000. Mr Madden, to whom we owe the most recent account (Travels in Turkey, 1829), states the number at 16,000, of whom 9000 are Arabs, 2000 Greeks, 2000 Franks (Europeans); the rest Jews, Copts, &c. The com¬ merce of Alexandria is still extensive, as almost all the commodities imported into and exported from Egypt pass through its port. Both the British and French na¬ tions maintain consuls at Alexandria, and of the former nation there are nine considerable mercantile houses esta¬ blished there. The Jewish merchants are also numerous and wealthy; for, though subject to heavier impositions, they carry on their traffic with such economy, and have such a friendly understanding with the collectors of the customs, that they generally undersell Europeans. The late extensive exportation of cotton from Egypt has given an increased importance to Alexandria, and a considerable stir has been created by the naval expedi¬ tions equipped there by the pacha. The present city is a kind of peninsula situated between the two ports. That to the westward was called by the ancients the Portus Eunostos, now the old port, and is by far the best; Turkish vessels only are allowed to an¬ chor there: the other, called the new port, is for the Christians ; at the extremity of one of the arms of which stood the famous Pharos. The new port, the only har¬ bour for Europeans, is clogged up with sand, insomuch that in stormy weather ships are liable to bilge; and the bottom being also rocky, the cables soon chafe and part; so that one vessel driving against a second, and that against a third, they are perhaps all lost. Of this there was a fatal instance many years ago, when 42 vessels were dashed to pieces on the mole in a gale of wind from the north-west; and numbers have been since lost there at different times. If it be asked in Europe, why do they not repair the new port ? the answer is, that in Turkey they destroy every thing, and repair nothing. The old harbour will be destroyed likewise, as the ballast of ves¬ sels has been continually thrown into it for the last 200 years. The spirit of the Turkish government is to ruin the labours of past ages, and destroy the hopes of future times, because ignorant despotism never considers to¬ morrow. The country round Alexandria is entirely destitute of water. This must be brought from the Nile by the ka- lidj, or canal of 12 leagues, which conveys it thither every year at the time of the inundation. It fills the vaults or reservoirs dug under the ancient city, and this provision must serve till the next year. It is evident, therefore, that were a foreign power to take possession, the canal would be shut, and all supplies of water cut off. It is this canal alone which connects Alexandria with Egypt; for, from its situation without the Delta, and the nature of the soil, it really belongs to the deserts of Africa. Its A1 environs are sandy, flat, and sterile, without trees and c ,n' without houses; where we meet with nothing but the^ V plant which yields the kali, and a row of palm-trees which follows the course of the kalidj or canal. The fa¬ mous tower of Pharos has long since been demolished and a castle, called Farillon, built in its place. The cause¬ way which joined the island to the continent is broken down, and its place supplied by a strong bridge of several arches. Some parts of the old walls of the city are yet stand¬ ing, and present a fine specimen of ancient masonry. They are flanked with large towers, about 200 paces distant from each other, with small towers in the middle. Below are magnificent casemates, which may serve for galleries to walk in. In the lower part of the towers is a large square hall, the roof of which is supported by thick columns of Thebaic stone. Above are several rooms, over which are platforms more than 20 paces square. The ancient reservoirs, vaulted with so much art, which ex¬ tend under the whole town, remain almost entire at the end of 2000 years. Of Caesar’s palace there remain only a few porphyry pillars, and the front, which is almost entire, and very beautiful. The palace of Cleopatra was built upon the walls facing the port, having a gallery on the outside, supported by several fine columns. Not far from this pa¬ lace are two obelisks, vulgarly called Cleopatra’s Needles. They are of Thebaic stone, and covered with hierogly¬ phics. One is overturned, broken, and lying under the sand; the other is on its pedestal. These two obelisks, each of which is a single stone, are about 60 feet high, by seven feet square at the base. Denon, who went to Egypt along with the French army in 1798, supposed that these columns decorated the entrance of the palace of the Ptolemies, the ruins of which still exist at no great distance from the place of the obelisks. Towards the gate of Rosetta are five columns of marble, on the place formerly occupied by the porticoes of the gymnasium. The rest of the colonnade, the design of which was dis¬ coverable 100 years ago by Maillet, has since been de¬ stroyed by the barbarism of the Turks. But what most engages the attention of travellers is the pillar of Pompey, as it is commonly called, situated at a quarter of a league from the southern gate. It is composed of red granite. The capital, which is Corinthian, with palm leaves, and not indented, is nine feet high. The shaft and the upper member of the base are of one piece of nearly 90 feet long and nine in diameter. The base is a square of about 15 feet on each side. This block of marble, 60 feet in circumference, rests on twro layers ot stone bound together with lead; which, however, has not prevented the Arabs from forcing out several of them, to search for an imaginary treasure. The whole column has been said to be 117 feet high, but the most recent and careful estimates do not make it exceed 95. It is per¬ fectly well polished, and only a little shivered on the eastern side. Nothing can equal the majesty of this mo¬ nument ; seen from a distance, it overtops the town, and serves as a signal for vessels. On a nearer approach, it produces an astonishment mixed with awe. One can never be tired with admiring the beauty of the capital) the length of the shaft, or the extraordinary simplicity of the pedestal. This last has been somewhat damage by the instruments of travellers, who are curious to pos¬ sess a relic of this antiquity. The column was considerec inaccessible, till it was scaled about half a century ago by the wild frolic of a party of English sailors, who conceive the project of emptying a bowl of punch on the top o A L E X A Ale, j. this celebrated monument. Dexterously availing them- dr selves of the movements of a paper kite, they succeeded fastening a rope to the summit, by which they ascend¬ ed, and performed this great achievement. They disco¬ vered a foot and ancle, the only remnant of a gigantic statue which had originally adorned it. It has since been rendered more accessible; and Mr Madden mentions an English lady who breakfasted and wrote a letter from this elevated position. Learned men and travellers have made many fruitless attempts to discover in honour of what prince it was erected. The best informed have concluded that it could not be in honour of Pompey, since neither Strabo nor Diodorus Siculus has spoken of it. The Arabian Abul- feda, in his Description of Egypt, calls it the Pillar of Se- rerus. And history informs us that this emperor visited the city of Alexandria. Denon, on this subject, expresses himself as follows:—“ After having observed that the column is very chaste both in style and execution; that the pedestal and capital are not formed of the same granite as the shaft; that their workmanship is heavy, and appears to be merely a rough draught; and that the foundations, made up of fragments, indicate a modern con¬ struction,—it may be concluded that this monument is not antique, and that it may have been erected, either in the time of the Greek emperors or of the caliphs; since, if the capital and pedestal are of sufficiently good workmanship to belong to the former of these periods, they are not so perfect but that art may have reached so far in the latter.” On the south-west side of the city, at a mile’s distance, are situated the catacombs, the ancient burial-place of Alexandria; a remarkable object, although they cannot be compared to those of the ancient Thebes. The Baron de Tott, in describing these, observes “ that Nature not hav¬ ing furnished this part of Egypt with a ridge of rocks, like that which runs parallel with the Nile above Delta, the ancient inhabitants of Alexandria could only have an imitation by digging into a bed of solid rock; and thus they formed a Necropolis, or City of the Dead. The excavation is from 30 to 40 feet wide, 200 long, and 25 deep, and is terminated by gentle declivities at each end. The two sides, cut perpendicularly, contain several open¬ ings, about 10 or 12 feet in width and height, hollowed horizontally; and which form, by their different branches, subterranean streets. One of these, which curiosity has disencumbered from the ruins and sands that render the entrance of others difficult or impossible, contains no mummies, but only the places they occupied. The order m which they were ranged is still to be seen. Niches, . 1”c"es square, sunk six feet horizontally, narrowed at the bottom, and separated from each other by partitions in the rock seven or eight inches thick, divided into c ‘^k^rs the two walls of this subterranean vault. It is natural to suppose, from this disposition, that each mummy was introduced with the feet foremost into the cellintend- n tor its reception; and that new streets were opened, in proportion as these dead inhabitants of Necropolis in¬ creased.’ This observation, he adds, which throws a 'r. it on tlie catacombs of Memphis, may perhaps likewise exp am the vast size and multitude, as well as the differ- en e evations, of the pyramids in Upper and Lower Egypt, bout 70 paces from Pompey’s pillar is the khalis, or e can'd of the Nile, which was dug by the ancient to convey the water of the Nile to Alexandria, i. i c*storns under the city. This canal had ceas- narl 0®et ler t0 navigable, till Mahmood, the present it fla’ sPent immense labour and cost in restoring it. ortunately, the Italian engineers whom he employed N D R I A. were entirely destitute of the skill necessary to conduct so great and arduous an undertaking. They took no mea¬ sures to protect the canal against the fresh influx of mud from the Nile, which accordingly has again choked it up to so great an extent, that it can scarcely be navigat¬ ed, unless during the season of inundation. Alexandria, in modern times, has never ranked as a fortress, and is considered by Volney as incapable of any defence. Accordingly, when attacked by Buonaparte m 1798,. it surrendered without a blow. The French were very industrious in forming the place, if not into a regu¬ lar fortress, yet into a very strong entrenched position. They appear to have succeeded. In 1801 Sir Ralph Abercromby undertook his memorable expedition. On the 13th and 21st March he gained, in the plain before Alexandria, two successive victories, of which the last was most complete and signal, though purchased by the life of the distinguished commander. Yet it was still not con¬ sidered possible to carry Alexandria, unless by regular siege; the conclusion of which, on the 2d September, was accompanied by a general convention for the evacu¬ ation of Egypt by the French armies. In 1806 a British force under General Frazer landed and took possession of Alexandria without resistance; but being repulsed in two successive attempts upon Rosetta, they finally evacuated it on the 21st June 1807. Alexandria is about 40 leagues north-west of Cairo. Long. 30. 10. E. Lat. 31.12. N. Alexandria, a circle in the western part of the go¬ vernment of Cherson.

II ^ ALEXANDRIAN, in a particular sense, is applied drowsk* those who professed or taught the sciences in the school of Alexandria. In this sense Clemens is de¬ nominated Alexandrinus, though born at Athens. The same may be said of Apion, who was born at Oasis; and Aristarchus, by birth a Samothracian. The chief Alex¬ andrian philosophers were, Ammonius, Plotinus, Origen, Porphyry, Jamblicus, Sopater, Maximus, and Dexippus. Alexandrian is more particularly understood of a col¬ lege of priests, consecrated to the service of Alexander Severus after his deification. Lampridius relates, that notwithstanding Severus was killed by Maximin, the se¬ nate prosecuted his apotheosis, and, for regularity of worship, founded an order of priests or sodales, under the denomination of Alexandrini. Alexandrian Manuscript, a famous copy of the Scrip¬ tures, consisting of four volumes, in a large quarto size, which contains the whole Bible in Greek, including the Old and New Testament, with the Apocrypha and some smaller pieces, but not quite complete. This manuscript is now preserved in the British Museum. It was sent as a present to King Charles I. from Cyrillus Lucaris, pat¬ riarch of Constantinople, by Sir Thomas Rowe, ambassa¬ dor from England to the grand signior, about the year 1628. Cyriilus brought it with him from Alexandria, where probably it was written. In a schedule annexed to it he gives this account,—that it was written, as tradition informed them, by Thecla, a noble Egyptian lady, about 1300 years ago, not long after the council of Nice. But this high antiquity, and the authority of the tradition to which the patriarch refers, have been disputed; nor are the most accurate Biblical writers agreed about its age. Grabe thinks that it might have been written before the end of the fourth century; others are of opinion that it was not written till near the end of the fifth century, or somewhat later. Alexandrian, or Alexandrine, in Poetry, a kind of verse consisting of 12, or of 12 and 13 syllables alternately; so called from a poem on the life of Alexander, written in this kind of verse by some French poet. Alexandrines are peculiar to modern poetry, and seem well adapted to epic poems. They are sometimes used by most nations of Europe, but chiefly by the French, whose tragedies are generally composed of Alexandrines. ALEXANDROW, a circle in the Russian province of Waldimir, to the west of the capital, watered by the Sera, and the smaller stream that enters it. The capital of the circle is the city of that name, in lat. 56. 25. N. and long. 38. 50. E. with 700 inhabitants. The circle contains also three large parishes, and an institution for breeding horses, where 300 brood-mares are supported by the government. ALEXANDROWSK, a circle in the Russian province of Jekaterinoslaw, on the east side of the Dnieper. It was formerly a frontier district towards Turkey, and pro¬ tected by seven fortresses, which are neglected and fast decaying. It is a poor, sandy, thinly peopled circle. The capital of the circle bears the same name. It stands on the river Dnieper, at the commencement of the ancient line of demarcation. It is fortified, contains 500 houses and 3000 inhabitants, and is a place of considerable transit trade. It is situated in long. 34. 53. E. and lat. 47. 44. N. Alexandrowsk, a market-town in the circle of Sophia, in the government of St Petersburg, in Russia. It stands on the Neva. In it are a sugar refinery, tanneries, and the imperial china manufactory.

It is on the lake Ladoga, Alt acu. and has extensive iron-works and founderies of cannon, \] with other branches of the manufacture of arms. ALEX1CACUS, something that preserves the body AliL from harm or mischief. The word amounts to much the^ v same as alexiterial. Alexicacus, in Antiquity, was an attribute of Neptune whom the tunny-fishers used to invoke under this appella¬ tion, that their nets might be preserved from the or sword-fish, which used to tear them ; and that he might prevent the assistance which it was pretended the dolphins used to give the tunnies on this occasion. ALEXIN, a circle in the province of Tula, of Russia in Europe, to the north of Moscow and east of Kaluga. It is a level district, watered by the river Oka and its tributary streams, of moderate fertility, and abundantly supplied with wood. It comprehends one city and 74 parishes, containing 241 villages and about 90,000 inhabitants. The capital of the circle, of the same name, is built on the river Oka, has three stone and one wooden church, with 1850 inhabitants, of whom some make hats, and others soap. It is in long. 36. 30. E. and lat. 54. 42. N. ALEXIPHARMICS, in Medicine, are properly reme¬ dies for expelling or preventing the ill effects of poison; but some of the moderns having imagined that the animal spirits in acute distempers were affected by a malignant poison, the term has been understood to mean medicines adapted to expel this poison by the cutaneous pores, in the form of sweat. In this sense, alexipharmics are the same as sudorifics. ALEXIS, a Piedmontese. There is a book of Secrets, which for a long time has gone under his name. It was printed at Basil in 1536, in 8vo, and translated from Italian into Latin by Wecher. It has also been translated into French, and printed several times, with additions. There is a preface to the piece, wherein Alexis informs us that he was born of a noble family; that he had from his most early years applied himself to study; that he had learned many languages; that having an extreme curiosity to be acquainted with the secrets of nature, he had collected as much as he could during his travels for 57 years; that he piqued himself upon not communicating his secrets to any person; but that when he was 82 years of age, having seen a poor man who had died of a sickness which might have been cured had he communicated his secret to the surgeon who took care of him, he was touched with such a remorse of conscience, that he lived almost like a hermit; and it was in this solitude that he arranged his secrets in such order as to make them fit to be published. The hawkers generally carry them, with other books, to the country fairs. These, however, contain only his select remedies, not his entire collection. ALEXITERIAL, among physicians, a term of much the same import with alexipharmic, though sometimes used in a synonymous sense with amulet. ALEYN, Charles, an English poet in the reign of Charles I. In 1631 he published two poems, entitled The Battailes of Cressy and Poictiers, under the fortunes and valour of King Edward of that name, and his sonne Edward prince of Wales, named the Black. He succeed¬ ed his father as clerk of the ordnance, and was commissary- general of the artillery to the king at the battle of Edge- hill. The next piece he wrote was a poem in honour of tt ttty t.i • . .1 a • .1 I. * i.L^ 01 Henry VII. and the victory that gained him the crown o England. In 1639, the year before he died, he translated the history of Eurialis and Lucretian, from the Latin epistles of .Tineas Sylvius. ALFAQUES, a seaport in the province of Catalonia, in Spain. It is on a peninsula formed by the river Ebro, near its mouth.

Universelle, tom. i.) Casiri gives a com¬ plete list of his writings, but it is too long to be copiedV in this place. (See Bibl. Arabico-Hispana Bscurialensis, tom. i.) Some of his pieces were published in the Latin tongue at Paris in 1633, under the title of Opuscula Varia Alfarabii. ALFARO, a town of Spain, on the confluence of . . Alhama with the Ebro, in the province of Soria. It is studied for some time at Bagdad, then the chief seat of surrounded with walls, and has four gates, one church, and learning; and afterwards travelled, in order to form an four monasteries, and 4800 inhabitants. It contains’four houses for soap-boiling, which produce 256 cwts.; three tanneries, and 28 looms for weaving linen.

He acquaintance with the learned of other countries A great revolution of sentiment in regard to letters had taken place, in the preceding century, among the followers of Mahomet. The commanders of the faithful had be¬ come the patrons and cultivators, instead of the scourgers and contemners, of science and literature. Knowledge found her only sanctuary under the successors of those rulers who had sought to extinguish every ray of intellec¬ tual light by means of the destruction of the libraries of the Calculator. He wrote an Introduction to Astronomy, A 1 /d o T r» o+rvo m /at tvv /a cj r» v i Ia i nr /Avr/Awr Ia/v/aH oo iio/aI/aoci ittIai/vIa ^a/ava 4- persisted in employing remedies of his own. Under t ns regimen his disorder rapidly increased, and at length ter- A L F I A ;ri. minated his life on the 8th October 1803, in the fifty-fifth ^ -^/year of his age. The character of Alfieri may be best appreciated from the portrait which he has drawn of himself in his own Memoirs of his Life. He was evidently of an irritable, impetuous, and almost ungovernable temper. Pride, which seems to have been a ruling sentiment, may account for many apparent inconsistencies of his character. While it made him abhor kings, because superior to himself, it led him to detest those republicans who, by too near an approach, contaminated aristocratic dignity; and it in¬ duced him, while yet undistinguished himself, and pant¬ ing for literary fame, to decline a proffered introduction to Metastasio and Rousseau. But as all his bad qualities were greatly softened by the cultivation of literature, it may be presumed, that a better education, and an earlier employment of his faculties, would have rendered him a much more perfect character. His application to study gradually tranquillized his temper and softened his man¬ ners, leaving him at the same time in perfect possession of those good qualities which he had inherited from na¬ ture,—a warm and disinterested attachment to his family and friends, united to a generosity, vigour, and elevation of character, which rendered him not unworthy to embody in his dramas the actions and sentiments of Grecian heroes. To these dramas Alfieri is chiefly indebted for the high reputation to which he has attained. Before his time the Italian language, so harmonious in the Sonnets of Petrarch, and so energetic in the Commedia of Dante, had been in¬ variably languid and prosaic in dramatic dialogue. The pedantic and inanimate tragedies of the sixteenth century were followed, during the iron age of Italian literature, by dramas, of which extravagance in the sentiments, and im¬ probability in the action, were the chief characteristics. The prodigious success of the Merope of Maftei, which ap¬ peared in the commencement of the last century, may be attributed more to a comparison with such productions, than to intrinsic merit. In this degradation of tragic taste, the appearance of the tragedies of Alfieri was perhaps the most important literary event that had occurred in Italy during the eighteenth century. On these tragedies it is difficult to pronounce a judgment, as the taste and system of the author underwent considerable change and modification during the intervals which elapsed between the three periods of their publication. An excessive harsh¬ ness of style, an asperity of sentiment, and total want of poetical ornament, are the characteristics of his first four tragedies, Filippo, Polinice, Antigone, and Virginia. These faults were in some measure corrected in the six trage¬ dies which he gave to the world some years after, and in those which he published along with Saul, the drama which enjoyed the greatest success of all his productions; a popularity which may be partly attributed to the severe and unadorned manner of Alfieri being well adapted to the patriarchal simplicity of the age in which the scene ol the tragedy is placed. But though there be a consid¬ erable dift’erence in his dramas, there are certain obser¬ vations applicable to them all. None of the plots are of his own invention. They are founded either on mytholo¬ gical fable or history ; most of them had been previously treated by the Greek dramatists, or by Seneca. Pos- munda, the only one which could be supposed of his own contrivance, and which is certainly the least happy effu¬ sion of his genius, is partly founded on the eighteenth novel of the third part of Bandello, and partly on Pre- vosts Memoires d'un Homme de Qualite. But whatever subjects he chooses, his dramas are always formed on the Grecian model, and breathe a freedom and independence "onhy of an Athenian poet. Indeed, his Agide and Bruto VOL. ii. ■ ERL may rather be considered oratorical declamations and dialogues on liberty, than tragedies. The unities of time and place are not so scrupulously observed in his as in the ancient dramas; but he has rigidly adhered to a unity of action and interest. He occupies his scene with one great action and one ruling passion, and removes from it every accessary event or feeling. In this excessive zeal for the observance of unity, he seems to have forgotten that its charm consists in producing a common relation between multiplied feelings, and not in the bare exhibi¬ tion of one, divested of those various accompaniments which give harmony to the whole. Consistently with that austere and simple manner which he considered the chief excellence of dramatic composition, he excluded from his scene all coups de theatre, all philosophical reflec¬ tions, and that highly ornamented versification which had been so assiduously cultivated by his predecessors. In his anxiety, however, to avoid all superfluous ornament, he has stripped his dramas of the embellishments of imagina¬ tion ; and for the harmony and flow of poetical language he has substituted, even in his best performances, a style which, though correct and pure, is generally harsh, ela¬ borate, and abrupt; often strained into unnatural ener¬ gy, or condensed into factitious conciseness. The chief excellence of Alfieri consists in powerful delineation of dramatic character. In his Philip II. he has represented, almost with the masterly touches of Tacitus, the sombre character, the dark mysterious counsels, the suspensa semper et obscura verba, of the modern Tiberius. In Polinice, the characters of the rival brothers are beauti¬ fully contrasted; in Maria Stuarda, that unfortunate queen is represented unsuspicious, impatient of contra¬ diction, and violent in her attachments. In Mirra, the character of Ciniro is perfect as a father and king, and Cecri is a model of the virtues of a wife and mother. In the representation of that species of mental alienation where the judgment has perished, but traces of character still remain, he is peculiarly happy. The insanity of Saul is skilfully managed ; and the horrid joy of Orestes in killing Egisthus rises finely and naturally to madness, in finding that, at the same time, he had inadvertently slain his mother. Whatever may be the merits or defects of Alfieri, he may be considered as the founder of a new school in the Italian drama. His country hailed him as her sole tragic poet; and his successors in the same path of literature have regarded his bold, austere, and rapid manner, as the genuine model of tragic composition. Besides his tragedies, Alfieri published during his life many sonnets, five odes on American independence, and the poem of Etruria, founded on the assassination of Alexander I. duke of Florence. Of his prose works, the most distinguished for animation and eloquence is the Panegyric on Trajan, composed in a transport of indig¬ nation at the supposed feebleness of Pliny’s eulogium. The two books, entitled La Tirannide and the Essays on Literature and Government, are remarkable for elegance and vigour of style, but are too evidently imitations of the manner of Machiavel. His Antigallican, which was writ¬ ten at the same time with his Defence of Louis XVI., comprehends an historical and satirical view of the Fr ench Revolution. The posthumous works of Alfieri consist of satires, six political comedies, and the Memoirs of his Life a work which will always be read with interest, in spite of the cold and languid gravity with which he de¬ lineates the most interesting adventures and the strongest passions of his agitated life.

A L F ALFORD, a town of Lincolnshire, situated on a small brook that runs through the town. A salt spring was discovered here in 1670, from the pigeons which flew thither in great numbers to drink the water, those birds being known to be fond of salt. It is recommended as cooling, cleansing, and attenuating ; as a good remedy in the scurvy, jaundice, and other glandular obstructions. It is six miles from the sea. The population in 1821 was 1506. Long. 0. 15. E. Lat. 53. 30. N. ALFRED, or tElfred, the Great, king of England, was the fifth and youngest son of iEthelwolf, king of the West Saxons, and was born at Wantage, in Berkshire, in 849. He distinguished himself, during the reign of his brother Ethelred, in several engagements against the Danes, and upon his death succeeded to the crown, in the year 871, and the 22d of his age. At his ascending the throne he found himself involved in a dangerous war with the Danes, and placed in such circumstances of distress as called for the greatest valour, resolution, and all the other virtues with which he was adorned. The Danes had already penetrated into the heart of his kingdom; and before he had been a month upon the throne, he was obliged to take the field against those formidable enemies. After many battles gained on both sides, he was at length reduced to the greatest distress, and was entirely aban¬ doned by his subjects. In this situation Alfred, conceiv¬ ing himself no longer a king, laid aside all marks of roy¬ alty, and took shelter in the house of one who kept his cattle. He retired afterwards to the isle of Aithelingey, in Somersetshire, where he built a fort for the security of himself, his family, and the few faithful servants who re¬ paired thither to him. When he had been about a year in this retreat, having been informed that some of his sub¬ jects had routed a great army of the Danes, killed their chief, and taken their magical standard,1 he issued his letters, giving notice where he was, and inviting his nobi¬ lity to come and consult with him. Before they came to a final determination, Alfred, putting on the habit of a harper, went into the enemy’s camp, where, without sus¬ picion, he was everywhere admitted, and had the honour to play before their princes. Having thereby acquired an exact knowledge of their situation, he returned in great secrecy to his nobility, whom he ordered to their respec¬ tive homes, there to draw together each man as great a force as he could; and upon a day appointed there was to be a general rendezvous at the great wood called Selwood, in Wiltshire. This affair was transacted so secretly and expeditiously, that, in a little time, the king, at the head of an army, approached the Danes, before they had the least intelligence of his design. Alfred, taking advantage of the surprise and terror they were in, fell upon them, and totally defeated them at fEthendune, now Eddington. Those who escaped fled to a neighbouring castle, where they were soon besieged, and obliged to surrender at dis¬ cretion. Alfred granted them better terms than they could expect. He agreed to give up the whole kingdom of the East Angles to such as would embrace the Christian reli- A L F gion, on condition that they would oblige the rest of their AH countrymen to quit the island, and, as much as was in^s their power, prevent the landing of any more foreigners. For the performance thereof he took hostages; and when in pursuance of the treaty, Guthrum the Danish captain came, with thirty of his chief officers, to be baptized, Al¬ fred answered for him at the font, and gave him the name of JEthelstane; and certain laws were drawn up betwixt the king and Guthrum for the regulation and government of the Danes settled in England. In 884 a fresh number of Danes landed in Kent and laid siege to Rochester; but the king coming to the relief of that city, they were obliged to abandon their design. Alfred had now great success, which was chiefly owing to his fleet, an advan¬ tage of his own creating. Having secured the sea-coasts, he fortified the rest of the kingdom with castles and walled towns; and he besieged and recovered from the Danes the city of London, which he resolved to repair, and to keep as a frontier.2 After some years’ respite, Alfred was again called into the field; for a body of Danes, being worsted in the west of France, came with a fleet of 250 sail on the coast of Kent, and having landed, fixed themselves at Appletree. Shortly after, another fleet of eighty vessels coming up the Thames, the men landed, and built a fort at Middleton. Before Alfred marched against the enemy, he obliged the Danes settled in Northumberland and Essex to give him hostages for their good behaviour. He then moved to¬ wards the invaders, and pitched his camp between their armies, to prevent their junction. A great body, however, moved off to Essex, and, crossing the river, came to Farn- ham in Surrey, where they were defeated by the king’s forces. Meanwhile the Danes settled in Northumberland, in breach of treaty, and notwithstanding the hostages given, equipped two fleets, and, after plundering the northern and southern coasts, sailed to Exeter and be¬ sieged it. The king, as soon as he received intelligence, marched against them; but before he reached Exeter they had got possession of it. He kept them, however, blocked up on all sides, and reduced them at last to such extremities, that they were obliged to eat their horses, and were even ready to devour each ether. Being at length rendered desperate, they made a general sally on the besiegers; but were defeated, though with great loss on the king’s side. The remainder of this body of Danes fled into Essex, to the fort they had built there, and to their ships. Before Alfred had time to recruit himself, another Danish leader, whose name was Laf, came with a great army out of Northumberland, and destroyed all be¬ fore him, marching on to the city of Werheal in the west, which is supposed to be Chester, where they remained the rest of that year. The year following they invaded North Wales; and after having plundered and destroyed every thing, they divided, one body returning to Northum¬ berland, another into the territories of the East Angles, from whence they proceeded to Essex, and took posses¬ sion of a small island called Meresig. Here they did not 1 “ This,” says Sir John Spelman, “ was a banner, with the image of a raven magically wrought by the three sisters of Hinguar and Hubba, on purpose for their expedition, in revenge of their father Lodebroeh’s murder; made, they say, almost in an instant, be¬ ing by them at once begun and finished in a noontide, and believed by the Danes to have carried great fatality with it, for which it was highly esteemed by them. It is pretended, that being carried in a battle, towards good success it would always seem to clap its wings, and make as if it would fly ; but towards the approach of mishap, it would hang down and not move.” {Life of Alfred, p. ol-l 2 The Danes had possessed themselves of London in the time of his father, and had held it till now as a convenient place for them to land at, and fortify themselves in ; neither was it taken from them but by a close siege. However, when it came into the kjng3 hands, it was in a miserable condition, scarcely habitable, and all its fortifications ruined. The king, moved by the importance ot t ic place, and the desire of strengthening his frontier against the Danes, restored it to its ancient splendour. And observing, that throng the confusion of the times, many, both Saxons and Danes, lived in a loose, disorderly manner, without owning any government, m offered them now a comfortable establishment, if they would submit and become his subjects. This proposition was better receive than he expected; for multitudes, growing weary of a vagabond kind of life, joyfully accepted such an offer. {Chron. Sax. p. 880 A L F 4-ed. long remain; for having separated, some sailed up the river Thames, and others up the Lea road, where, draw¬ ing up their ships, they built a fort not far from London, which proved a great check upon the citizens, who went in a body and attacked it, but were repulsed with great loss. At harvest-time the king himself was obliged to en¬ camp with a body of troops in the neighbourhood of the city, in order to cover the reapers from the excursions of the Danes. As he was one day riding by the side of the river Lea, after some observations he began to think that the Danish ships might be laid quite dry: this he at¬ tempted, and having succeeded, the Danes were forced to desert their fort and ships, and march away to the banks of the Severn where they built a fort, and wintered at a place called Qmtbrig.x Such of the Danish ships as could be got off, the Londoners carried into their own road; the rest they burned and destroyed. Alfred enjoyed a profound peace during the last three years of his reign, which he chiefly employed in establish¬ ing and regulating his government, for the security of himself and his successors, as well as the ease and benefit of his subjects in general. After a troublesome reign of 28 years, he died on the 28th of October a. d. 900, and was buried at Winchester, in Hyde-abbey, under a monu¬ ment of porphyry. All our historians agree in distinguishing him as one of the most valiant, wisest, and best of kings that ever reigned in England; and it is also generally allow'ed, that he not only digested several particular laws still in being, but that he laid the first foundation of our present happy constitution. There is great reason to believe that we are indebted to this prince for trials by juries; and the Doomsday Book, which is preserved in the Exchequer, is thought to be no more than another edition of Alfred’s book of Winchester, which contained a survey of the kingdom. It is said also that he was the first who divided the kingdom into shires. What is ascribed to him is not a bare division of the country, but the settling of a new form of judicature ; for after having divided his dominions into shires, he subdi¬ vided each shire into three parts, called trytlungs. There are some remains of this ancient division in the ridings of Yorkshire, the laths of Kent, and the three parts of Lin¬ colnshire. Each trything was divided into hundreds or wapentakes; and these again into tythings or dwellings of ten householders. Each of these householders stood engaged to the king, as a pledge for the good behaviour of his family, and all the ten were mutually pledges for each other; so that if any one of the tythings was sus¬ pected of an offence, if the head-boroughs or chiefs of the tythings would not be security for him, he was impri¬ soned; and, if he made his escape, the tything and hun¬ dred were fined to the king. Each shire was under the government of an earl, under whom was the reive, his deputy, since, from his office, called shire-reive, or she- . -^nti so effectual were these regulations, That it is said he caused bracelets of gold to be hung up in the ighways, as a challenge to robbers; and they remained untouched. ^ In private life Alfred was the most amiable man in his omimons; of so equal a temper, that he never suffered cit ier sadness or unbecoming gaiety to enter his mind; u appeared always of a calm yet cheerful disposition, ami iar to his friends, just even to his enemies, kind and render to all. He was a remarkable economist of his A L F time; and Asserius has given us an account of the me- lod he took for dividing and keeping an account of it.' He caused six wax-candles to be made, each of 12 inches long, and of as many ounces weight; on the candles the inches were regularly marked, and having found that one of them burned just four hours, he committed them to the care of the keepers of his chapel, who from time to time gave him notice how the hours went. But as in windy weather the candles were wasted by the impression of the air on the flame, to remedy this inconvenience he invent- ed lanthorns, there being then no glass in his dominions. Hus prince, we are told, was 12 years of age before a master could be procured in the western kingdom to teach him the alphabet; such was the state of learning when Alfred began to reign. He had felt the misery of igno¬ rance, and determined even to rival his contemporary Charlemagne in the encouragement of literature. He is supposed to have appointed persons to read lectures at Oxford, and is thence considered as the founder of that university. By other proper establishments, and by a general encouragement to men of abilities, he did every thing in his power to diffuse knowledge throughout his dominions. Nor was this end promoted more by his countenance and encouragement than by his own example and his writings; for notwithstanding the lateness of his initiation, he had acquired extraordinary erudition; and, had he not been illustrious as a king, he would have been famous as an author. His works are, 1. Breviarium quod- dam collectum ex Begibus Trojanorum, &c. lib. i.; a Bre¬ viary collected out of the Laws of the Trojans, Greeks, Britons, Saxons, and Danes, in one book. Leland saw this book in the Saxon tongue, at Christ-Church, in Hamp¬ shire. 2. Visi-Saxonum Leges, lib. i.; the Laws of the West Saxons, in one book. Pitts tells us that it is in Bennet-College library, at Cambridge. 3. Instituta qucedam, lib. i.; certain Institutes, in one book. This is mentioned by Pitts, and seems to be the second capitulation with Guthrum. 4. Contra Judices Iniquos, lib. i.; an invec¬ tive against Unjust Judges, in one book. 5. Acta Magis- tratuum suorum, lib. i.; Acts of his Magistrates, in one book. This is supposed to be the Book of Judgments men¬ tioned by Horne, and was in all probability a kind of Reports intended for the use of succeeding ages. 6. Re¬ gum Fortunes varies, lib. i.; the various Fortunes of Kings, in one book. 7. Dicta Sapientum, lib. i.; the Sayings of Wise Men, in one book. 8. Paraboles et Sales, lib. i.; Parables and pleasant Sayings, in one book. 9. Collec- tiones Chronicorum, Collection of Chronicles. 10. Epis- toles ad Wulfsigium Episcopum, lib. i.; Epistles to Bishop Wulfsig, in one book. 11. Manuals Meditationum, a Manual of Meditations.—Besides those original works, he translated many authors from the Latin, &c. into the Saxon language, viz. 1. Bede’s History of England. 2. Paulinus Orosinus’s History of the Pagans. 3. St Gregory’s Pastoral, &c. The first of these, with his pre¬ faces to the others, together with his laws, were printed at Cambridge, 1644. His laws are likewise inserted in Spelman’s Councils. 4. Boethius de Consolations, lib. v.; Boethius’s Consolations of Philosophy, in five books. Dr Plot tells us King Alfred translated it at Woodstock, as he found in a MS. in the Cotton Library. 5.

It was, howevef, Algebra, completed by another hand, and published at London in 1640, in quarto, by Sir John Spelman. Several others are mentioned by Malmsbury, and the old history of Ely asserts that he translated the Old and New Testaments. The life of this great king was written by Asserius Me- nevensis, and published by Archbishop Parker, in the old Saxon character, at the end of his edition of Hessing- ham’s history, printed in 1674, folio.

Led by curi¬ osity, as well as a desire of improvement, he travelled early into foreign countries; and was very young when he arrived in France in 1736. Here he composed his Newtonian Philosophy for the Ladies, as hontenelle had done his Cartesian Astronomy, in the work entitled The Plurality of Worlds. He was noticed by the king of Prussia, who gave him marks of the esteem he had for him. He died at Pisa the 23d of May 1764, and ordered his own mausoleum, with this inscription to be fixed upon it, Hie jacet Algarottus, sed non omnis. He is allowed to have been a very great connoisseur in painting, sculp¬ ture, and architecture. He contributed much to the re¬ formation of the Italian opera. His works, which are nu¬ merous, and upon a variety of subjects, abound with viva¬ city, elegance, and wit. They were printed at Leghorn in 1765, in 4 vols. 8vo. ALGARVE, a province of Portugal, the most southern Alo¬ of the kingdom. It is divided from the Spanish province | of Andalusia by the river Guadiana. On the north it is % bounded by the province of Alentejo, and on the south'^ and west by the Atlantic Ocean. It is the smallest divi¬ sion of Portugal, and is very thinly peopled. Its extent is 232 square leagues, and the number of inhabitants 127,615. On the northern part, towards Alentejo, the Sierras de Caldeyraron and Monchique rise to a great height. The roads are very bad, the soil unfruitful, and the inhabitants few in those districts. Numerous flocks of goats are bred, and some other cattle are pastured. The country on the coast is more fruitful, and produces abundant harvests of grapes, figs, oranges, lemons, olives, and almonds, considerable quantities of which are shipped from the seaport to the different countries in the north of Europe. Very little wheat or other corn is grown in this province, but the inhabitants draw their principal supply from the adjoining provinces of Spain. On the coasts the people derive their subsistence in a great measure from the fisheries; and both the tunny and sardinias are caught in very considerable quantities. The rivers are of short course, running from north to south, and at their mouths ves¬ sels may enter at high tide; but the harbours on the whole coast ax*e bad, though near Tavira, the principal city, some islands afford shelter, and allow of good anchorage for large vessels behind them. The wdiole of the foreign trade from the various ports in Algarve is carried on in the vessels of other countries, as there are scarcely any other than fishing boats owned by the inhabitants of the ports. The name Algarve is derived from an Arabic word which signifies westward. The province is desig¬ nated by the name of kingdom, and gives one of the titles to the Portuguese monarch. This province contains 4 cities, 14 towns, 63 villages, 71 parishes, and 25,503 hearths. It is situated between lat. 36.56. and 37.30. N. ALGEBRA. INTRODUCTION. A LGEBRA is a branch of the mathematics, which has for its object whatever can be expressed by num¬ ber, either exactly or by approximation. In this respect, and also in its employing arbitrary signs to denote the things of which it treats, it agrees with arithmetic. The analogy between the two sciences in¬ duced Sir Isaac Newton to denominate it Universal Arith¬ metic ; but by the application of algebra to geometry, the science has acquired a new character and new powers, which render this appellation too limited, and not suffi¬ ciently descriptive of its nature. In its present state it is nearly alike related to arithmetic and geometry. In its application to both sciences, the reasoning is carried on by general symbols: its true character consists in this, that the results of its operations do not exhibit the indi¬ vidual values of the quantities which are the subject of in¬ vestigation, such as we obtain in arithmetical calculations or geometrical constructions. They only indicate the operations, whether arithmetical or geometrical, which ought to be performed on the given quantities, to obtain the value of the quantities sought. It has been a question much agitated, at what period and in what country was algebra invented ? Who were the earliest writers on the subject ? What was the pro¬ gress of its improvement ? And lastly, by what means, and at what period, was the science diffused over Europe? It was a common opinion in the 17th century, that the ancient Greek mathematicians must have possessed an analysis of the nature of modern algebra, by which they discovered the theorems and solutions of the problems which we so much admire in their writings; but that they carefully concealed their instruments of investigation, and gave only the results, with synthetic demonstrations. This opinion is, however, now exploded. A more inti¬ mate acquaintance with the writings of the ancient geo¬ meters has shown that they had an analysis, but that it was purely geometrical, and essentially different from our algebra. Although there be no reason to suppose that the great geometers of antiquity derived any aid in their discove¬ ries from the algebraic analysis, yet we find, that at a considerably later period it was known to a certain ex¬ tent among the Greeks. About the middle of the 4th century of the Christian era, a period when the mathematical sciences were on the decline, and their cultivators, instead of producing origi¬ nal works of genius, contented themselves with commen¬ taries on the works of their more illustrious predecessors, there was a valuable addition made to the fabric of ancient learning. Al^.a. x - ALGEBRA. This was the treatise of Diophantus on arithmetic, j which originally consisted of thirteen books, but of which only the first six, and an incomplete book on polygonal numbers, supposed to be the thirteenth, have descended to our times. This precious fragment does not exhibit any thing like a complete treatise on algebra. It rather is an applica¬ tion of its doctrines to a peculiar class of arithmetical questions, which belong to what is now called the inde¬ terminate analysis. Diophantus may have been the inventor of the Greek algebra, but it is more likely that its principles were not unknown before his time; and that, taking the science in the state he found it as the basis of his labours, he en¬ riched it with new applications. The elegant solutions of Diophantus show that he possessed great address in the particular branch of which he treated, and that he was able to resolve determinate equations of the second de¬ gree. Probably this was the greatest extent to which the science had been carried among the Greeks. Indeed, in no country did it pass this limit, until it had been trans¬ planted into Italy on the revival of learning. The celebrated Hypatia, the daughter of Theon, com¬ posed a commentary on the work of Diophantus. This, however, is now lost, as well as a similar labour of this illustrious and ill-fated lady on the Conics of Apollonius. It is commonly known that she fell a sacrifice to the fury of a fanatical mob about the beginning of the 5th century. About the middle of the 16th century, the work of Diophantus, written in the Greek language, was disco¬ vered at Rome in the Vatican library, where probably it had been carried from Greece when the Turks possessed themselves of Constantinople. A Latin translation, with¬ out the original text, was given to the world by Xylander in 1575; and a more complete translation, by Bachet de Mezeriac (one of the oldest members of the French aca¬ demy), accompanied by a commentary, appeared in 1621. Bachet was eminently skilful in the indeterminate analysis, and therefore well qualified for the work he had under¬ taken; but the text of Diophantus wras so much injured, that he was frequently obliged to divine the meaning of the author, or supply the deficiency. At a later period, the celebrated French mathematician Fermat, in addition to the commentary of Bachet, added notes of his own on the writings of the Greek algebraist. These are extremely valuable, on account of Fermat’s profound knowledge of this particular branch of analysis. This edition, the best which exists, appeared in 1670. Although the revival of the writings of Diophantus was an important event in the history of the mathematics, yet it was not from them that algebra became first known in Europe. This important invention, as well as the numeral characters and decimal arithmetic, was re¬ ceived from the Arabians. That ingenious people fully approciated the value of the sciences; for at a period when all Europe was enveloped in the darkness of igno¬ rance, they preserved from extinction the lamp of know¬ ledge. They carefully collected the writings of the Greek mathematicians; they translated them into their language, and illustrated them with commentaries. It was through me medium of the Arabic tongue that the elements of Euclid were first introduced into Europe ; and a part of t ie writings of Apollonius are only known at the present day by a translation from the Arabic, the Greek original eing probably irrecoverably lost. The Arabians ascribe e invention of their algebra to one of their mathemati- c>ans, Mahommed-Ben-Musa, or Moses, called also Ma- ^uz^ana» who flourished about the middle of le century, in the reign of the Caliph Almamon. ^ is certajn that this person composed a treatise on this subject, because an Italian translation was known at one time to have existed in Europe, although it be now lost. Fortunately, however, a copy of the Arabic original is preserved in the Bodleian Library at Oxford, bearino- a date of transcription corresponding to the year 1342. The title-page identifies its author with the ancient Ara¬ bian. A marginal note concurs in this testimony, and farther declares the work to be the first treatise composed on algebra among the faithful; and the preface, besides indicating the author, intimates that he was encouraged by Almamon, commander of the faithful, to compile a compendious treatise of calculation by algebra. The circumstance of this treatise professing to be only a compilation, and, moreover, the first Arabian work of the kind, has led to an opinion that it was collected from books in some other language. As the author was inti¬ mately acquainted with the astronomy and computations of the Hindoos, he may have derived his knowledge of algebra from the same quarter. Hence we may conclude, with some probability, that the Arabian algebra was ori¬ ginally derived from India. The algebraic analysis having been once introduced among the Arabians, it was cultivated by their own wri¬ ters. One of these, Mahommed Abulwafa, who flourished in the last forty years of the 10th century, composed commentaries on the writers who had preceded him. He also translated the writings of Diophantus. Probably this was the first translation that was made of the Greek alge¬ braist into the Arabian tongue. It is remarkable, that although the mathematical sci¬ ences were received with avidity, and sedulously culti¬ vated during a long period, by the Arabians, yet in their hands they received hardly any improvement. It might have been expected that an acquaintance with the writ¬ ings of Diophantus would have produced some change in their algebra. This, however, did not happen : their al¬ gebra continued nearly in the same state, from their ear¬ liest writer on the subject, to one of their latest, Behau- din, who lived between the years 953 and 1031. Writers on the history of algebra were long under a mis¬ take as to the time and manner of its introduction into Eu¬ rope. It has now, however, been ascertained that the sci¬ ence was brought into Italy by Leonardo, a merchant of Pisa. This ingenious man resided in his youth in Barbary, and there learned the Indian method of accounting by the nine numeral characters. Commercial affairs led him to travel into Egypt, Syria, Greece, and Sicily, where we may suppose he made himself acquainted with every thing known respecting numbers. The Indian mode of computation appeared to him to be by far the best. He accordingly studied it carefully; and, with this knowledge, and some additions of his own, and also taking some things from Euclid’s Geometry, he composed a treatise on arith¬ metic. At that period algebra was regarded only as a part of arithmetic. It was indeed the sublime doctrine of that science; and under this view the two branches were handled in Leonardo’s treatise, which was originally writ¬ ten in 1202, and again brought forward under a revised form in 1228. When it is considered that this work was composed two centuries before the invention of printing, and that the subject was not such as generally to interest mankind, we need not wonder that it was but little known; hence it has always remained in manuscript, as well as some others by the same author. Indeed it was not known to exist from an early period until the middle of the last century, when it was discovered in the Maglia- becchian library at Horence. The extent of Leonardo’s knowledge was pretty much. 422 ALGEBRA. Algebra, the same as that of the preceding Arabian writers. He Could resolve equations of the first and second degree, and he was particularly skilful in the Diophantine analysis. He was well acquainted with geometry, and he employed its doctrines in demonstrating his algebraic rules. Like the Arabian writers, his reasoning was expressed in words at length ; a mode highly unfavourable to the progress of the art. The use of symbols, and the method of combining them so as to convey to the mind at a single glance a long process of reasoning, was an invention considerably later than Leonardo’s time. Considerable attention was given to the cultivation of algebra between the time of Leonardo and the invention of printing. It was publicly taught by professors. Trea¬ tises were composed on the subject; and two works of the oriental algebraists were translated from the Arabian language into Italian. One was entitled the Rule of Al¬ gebra, and the other was the oldest of all the Arabian treatises, that of Mahommed-Ben-Musa of Corasan. The earliest printed book on algebra was composed by Lucas Paciolus, or Lucas de Burgo, a minorite friar. It was first printed in 1494, and again in 1523. The title is Summa de Arithmetica, Geometria, Proportioni, et Propor- tionalita. This is a very complete treatise on arithmetic, alge¬ bra, and geometry, for the time in which it appeared. The author followed close on the steps of Leonardo ; and, indeed, it is from this work that one of his lost treatises has been restored. Lucas de Burgo’s work is interesting, inasmuch as it shows the state of algebra in Europe about the year 1500: probably the state of the science was nearly the same in Arabia and Africa, from which it had been re¬ ceived. The power of algebra as an instrument of research is in a very great degree derived from its notation, by which all the quantities under consideration are kept con¬ stantly in view; but in respect of convenience and bre¬ vity of expression, the algebraic analysis in the days of Lucas de Burgo was very imperfect: the only symbols employed were a few abbreviations of the words or names which occurred in the processes of calculation, a kind of short-hand, which formed a very imperfect substitute for that compactness of expression which has been attained by the modern notation. The application of algebra was also at this period very limited; it was confined almost entirely to the resolution of certain questions of no great interest about numbers. No idea was then entertained of that extensive applica¬ tion which it has received in modern times. The knowledge which the early algebraists had of their science was also circumscribed; it extended only to the resolution of equations of the first and second degree; and they divided the last into cases, each of which was resolved by its own particular rule. The important ana¬ lytical fact, that the resolution of all the cases of a pro¬ blem may be comprehended in a single formula, which may be obtained from the solution of one of its cases, merely by a change of the signs, was not then known : in¬ deed it was long before this principle was fully compre¬ hended. Dr Halley expresses surprise, that a formula in optics which he had found, should by a mere change of the signs give the focus of both converging and diverging rays, whether reflected or refracted by convex or concave spe¬ cula or lenses ; and Molyneux speaks of the universality of Halley’s formula as something that resembled magic. The rules of algebra may be investigated by its own principles, without any aid from geometry; and although in some cases the two sciences may serve to illustrate the doctrines of each other, there is now not the least neces- A1 sity in the more elementary parts to call in the aid ofthe1^ ^ latter to the former. It was otherwise in former times. Lucas de Burgo found it to be convenient, after the ex¬ ample of Leonardo, to employ geometrical constructions to prove the truth of his rules for resolving quadratic equations, the nature of which he did not completely com¬ prehend ; and he was induced by the imperfect nature of his notation to express his rules in Latin verses, which will not now be read with the satisfaction we receive from the perusal of the well-known poem, “ the Loves of the Triangles.” As it was in Italy that algebra became first known in Europe, so it was there that it received its earliest im¬ provements. The science had been nearly stationary from the days of Leonardo to the time of Paciolus, a period of three centuries; but the invention of printing soon excited a spirit of improvement in all the mathematical sciences. Hitherto an imperfect theory of quadratic equations was all the extent to which it had been carried. At last this boundary was passed, and about the year 1505 a particu¬ lar case of equations of the third degree was resolved by Scipio Ferreus, a professor of mathematics in Bononia. This was an important step, because it showed that the difficulty of resolving equations of the higher orders, at least in the case of the third degree, was not insurmount¬ able, and a new field was opened for discovery. It was then the practice among the cultivators of algebra, when they advanced a step, to conceal it carefully from their contemporaries, and to challenge them to resolve arithme¬ tical questions, so framed as to require for their solution a knowledge of their own new-found rules. In this spirit did Ferreus make a secret of his discovery: he com¬ municated it, however, to a favourite scholar, a Venetian named Florido. About the year 1535 this person, having taken up his residence at Venice, challenged Tartalea of Brescia, a man of great ingenuity, to a trial of skill in the resolution of problems by algebra. Florido framed his questions so as to require for their solution a knowledge of the rule which he had learned from his preceptor Fer¬ reus ; but Tartalea had, five years before this time, ad¬ vanced farther than Ferreus, and was more than a match for Florido. He therefore accepted the challenge, and a day was appointed when each was to propose to the other thirty questions. Before the time came, Tartalea had re¬ sumed the study of cubic equations, and had discovered the solution of two cases in addition to two which he knew before. Florido’s questions were such as could be resolved by the single rule of Ferreus; while, on the con¬ trary, those of Tartalea could only be resolved by one or other of three rules, which he himself had found, but which could not be resolved by the remaining rule, which was also that known to Florido. The issue of the contest is easily anticipated; Tartalea resolved all his adversarys questions in two hours, without receiving one answer from him in return. The celebrated Cardan was a contemporary of Tartalea. This remarkable person was a professor of mathematics at Milan, and a physician. He had studied algebra with great assiduity, and had nearly finished the printing of a book on arithmetic, algebra, and geometry; but being desirous oi enriching his work with the discoveries of Tartalea, which at that period must have been the object of considerable attention among literary men in Italy, he endeavoured to draw from him a disclosure of his rules. Tartalea resist¬ ed for a time Cardan’s entreaties. At last, overcome by his importunity, and his offer to swear on the holy Evange¬ lists, and by the honour of a gentleman, never to publish them, and on his promising on the faith of a Christian to ALGEBRA. Al*ra. commit them to cypher, so that even after his death they would be unintelligible to any one, he ventured with much hesitation to reveal to him his practical rules, which, were expressed by some very bad Italian verses, themselves in no small degree enigmatical. He reserved, however, the demonstrations. Cardan was not long in discovering the reason of the rules, and he even greatly improved them, so as to make them in a manner his own. From the imper¬ fect essays of Tartalea, he deduced an ingenious and sys¬ tematic method of resolving all cubic equations whatso¬ ever; but with a remarkable disregard for the principles of honour, and the oath he had taken, he published, in 1545, Tartalea’s discoveries, combined with his own, as a supplement to a treatise on arithmetic and algebra, which he had published six years before. This work is remark¬ able for being the second printed book on algebra known to have existed. In the following year Tartalea also published a work on algebra, which he dedicated to Henry VIII. king of Eng¬ land. It is to be regretted that in many instances the authors of important discoveries have been overlooked, while the honours due to them have been transferred to others having only secondary pretensions. The formula for the resolution of cubic equations are now called Cardan’s rules, notwithstanding the prior claim of Tartalea. It must be confessed, however, that he evinced considerable selfish¬ ness in concealing his discovery; and although Cardan cannot be absolved from the charge of bad faith, yet it must be recollected that by his improvements in what Tartalea communicated to him, he made the discovery in some measure his own; and he had moreover the high merit of being the first to publish this important improve¬ ment in algebra to the world. The next step in the progress of algebra was the dis¬ covery of a method of resolving equations of the fourth order. An Italian algebraist had proposed a question which could not be resolved by the newly invented rules, because it produced a biquadratic equation. Some sup¬ posed that it could not be at all resolved; but Cardan was of a different opinion : he had a pupil named Lewis Fer¬ rari, a young man of great genius, and an ardent student m the algebraic analysis: to him Cardan committed the solution of this difficult question, and he was not disap¬ pointed. Ferrari not only resolved the question, but he also found a general method of resolving equations of the fourth degree, by making them depend on the solution of Equations of the third degree. Ibis was another great improvement; and although the precise nature of an equation was not then fully under¬ stood, nor was it indeed until half a century later, yet, in ie general resolution of equations, a point of progress was ion reached which the utmost efforts of modern analyses have never been able to pass. There was another Italian mathematician of that period ^ 10 contributed somewhat to the improvement of algebra. •is was Bombelli. He published a valuable work on the suyect m 1572, in which he brought into one view what 'a( been done by his predecessors. He explained the U^.e 0 ^e irreducible case of cubic equations, which had ^ T perplexed Cardan, who could not resolve it by his L'c'.’ , showed that the rule would apply sometimes to arWff1 T ®xainl^es’ and that all equations of this case r 1 , a real solution; and he made the important ar , that the algebraic problem to be resolved in this se coi responds to the ancient problem of the trisection ot an angle. Th ^ wiffi pre^ere two German mathematicians contemporary ardan and lartalea, viz. Stifelius and Scheubelius. Their writings appeared about the middle of the IGth century, before they knew what had been done by the Italians. Their improvements were chiefly in the nota¬ tion. otifelms, m particular, introduced for the first time the characters which indicate addition and subtraction and the symbol for the square root. ’ The fiist treatise on algebra in the English language was written by Robert Recorde, teacher of mathematics and practitioner in physic at Cambridge. At this period it was common for physicians to unite with the healing art the studies of mathematics, astrology, alchemy, and chemistry. This custom was derived from the Moors who were equally celebrated for their skill in medicine and calculation. In Spain, where algebra was early known, the title of physician and algebraist were nearly synony- mous. Accordingly, in the romance of Don Quixotte, when the bachelor Samson Carasco was grievously wounded in his rencounter with the knight, an algebrista was called in to heal his bruises. Recorde published a treatise on arithmetic, which was dedicated to Edward VI.; and another on algebra, with this title, “ The Whetstone of Wit,” Ac. Here, for the first time, the modern sign for equality was introduced. By such gradual steps did algebra advance in improve¬ ment from its first introduction by Leonardo, each suc¬ ceeding writer making some change for the better; but with the exception of Tartalea, Cardan, and Ferrari, hardly any one rose to the rank of an inventor. At length came Vieta, to whom this branch of mathematical learning, as well as others, is highly indebted. His improvements in algebra were very considerable ; and some of his inven¬ tions, although not then fully developed, have yet been the germs of later discoveries. He was the first that em¬ ployed general characters to represent known as well as unknown quantities. Simple as this step may appear, it has yet led to important consequences. He must also be regarded as the first that applied algebra to the improve¬ ment of geometry. The older algebraists had indeed re¬ solved geometrical problems, but each solution was parti¬ cular; whereas Vieta, by introducing general symbols, produced general formula?, which were applicable to all problems of the same kind, without the trouble of going over the same process of analysis for each. This happy application of algebra to geometry has pro¬ duced great improvements: it led Vieta to the doctrine of angular sections, one of the most important of his dis¬ coveries, which is now expanded into the arithmetic or calculus of sines. He also improved the theory of alge¬ braic equations, and he was the first that gave a general method of resolving them by approximation. As he lived between the years 1540 and 1603, his writings belong to the latter period of the 16th century. He printed them at his own expense, and liberally bestowed them on men of science. The Flemish mathematician Albert Girard was one of the improvers of algebra. He extended the theory of equations somewhat farther than Vieta, but he did not completely unfold their composition ; he was the first that showed the use of the negative sign in the resolution of geometrical problems, and he also first spoke of imaginary quantities, a subject not yet completely cleared up; and he inferred by induction that every equation has precisely as many sorts as there are units in the number that ex¬ presses its degree. His algebra appeared in 1629. The next great improver of algebra was Thomas Har¬ riot, an Englishman. As an inventor he has been the boast of this country. The French mathematicians have accused the British of giving discoveries to him which were really due to Vieta. It is probable that some of 424 Algebra. A L G E these may be justly claimed for both, because each may have made the discovery for himself, without knowing what had been done by the other. Harriot’s principal discovery, and indeed the most important ever made in algebra, was, that every equation may be regarded as formed by the product of as many simple equations as there are units in the number expressing its order. This important doctrine, now familiar to every student of alge¬ bra, was yet slowly developed: it was quite within the reach of Vieta, who unfolded it in part, but left its com¬ plete discovery to Harriot. _ We have seen the very inartificial form in which alge¬ bra first appeared in Europe. The improvements of al¬ most 400 years had not given its notation that compact¬ ness and elegance of which it is susceptible. Harriot made several changes in the notation, and added some new signs: he thus gave to algebra greater symmetry o form. Indeed, as it came from his hands, it diffeied but little from its state at the present time. Oughtreed, another early English algebraist, was a con¬ temporary with Harriot, but lived long after him. He wrote a treatise on the subject, which was long taught in the universities. In tracing the history of algebra, we have seen, that in the form under which it was received from the Arabs, it was hardly distinguishable as a peculiar mode of leason- ing, because of the want of a suitable notation ; and that, poor in its resources, its applicability was limited to the resolution of a small number of uninteresting numeral questions. Wb have followed it through different stages of improvement, and we are now arrived at a period when it was to acquire additional power as an instrument of analysis, and to admit of new and more extended applica¬ tions. Vieta saw the great advantage that might be de¬ rived from the application of algebra to geometry. The essay he made in his theory of angular sections, and the rich mine of discovery thus opened, proved the import¬ ance of his labours. He did not fully explore it, but it has seldom happened that one man began and completed a discovery. He had, however, an able and illustrious suc¬ cessor in Descartes, who, employing in the study of alge¬ bra that high power of intellect with which he was en¬ dowed, not only improved it as an abstract science, but, more especially by its application to geometry, he laid the foundation of the great discoveries which have since so much engaged mathematicians, and made the last two centuries ever memorable in the history of the progress of the human mind. Descartes’s grand improvement was the application of algebra to the doctrine of curve lines. As in geography we refer every place on the earth’s surface to the equator, and to a determinate meridian, so he referred every point of a curve to some line given by position. For example, in a circle, every point in the circumference might be re¬ ferred to the diameter. The perpendicular from any point in the curve, and the distance of that perpendicular from the centre or from the extremity of a diameter, were lines which, although varying with every change of position in the point from which the perpendicular was drawn, yet had a determinate relation to each othqr, which was the same for all points in the curve, which depended on its nature, and which, therefore, served as a characteristic to distinguish it from all other curves. The relations of lines drawn in this way could be readily expressed in algebraic symbols; and the combination of these constituted what is called the equation of the curve. This might serve as its definition; and from the equa¬ tion by the processes of algebra, all the properties of the curve could be investigated bra. Descartes’s geometry (or, as it might have been named, ai< the application of algebra to geometry) appeared first inV^ 1637. This was six years after the publication of Har¬ riot’s discoveries, which was a posthumous work. Des¬ cartes availed himself of some of Harriot’s views, particu¬ larly the manner of generating an equation without ac¬ knowledgement ; and on this account Dr Wallis, in his algebra, has reflected with considerable severity on the French algebraist. This spirit has engendered a corresponding eagerness in the French mathematicians to defend him. Montucla, in his history of the mathematics, has evinced a strong national prejudice in his favour; and, as usually happens, in order to exalt him, he hardly does justice to Harriot, the idol of his adversaries. In treating of the claims of algebra and geometry to be considered as kindred sciences, a question arises, why was this relation not sooner perceived and appreciated? The sciences of geometry and algebra have each had a distinct origin. The former is the more ancient, and no doubt for this reason, that its principles are less removed from the ordinary affairs of men. The subjects of geo¬ metry, extension, and figure are continually presented to attention ; and the elements of the science are to a cer¬ tain extent employed in the most ordinary arts of life. We cannot sufficiently admire the ingenuity with which the natural geometry of the early times had been wrought up into a system more than two thousand years ago; but when we consider that its assistance was wanted in the partition of land, in the erection of houses and temples, and numberless other cases, we need not wonder at the early progress of the science among such an ingenious people as the ancient Greeks. Algebra, however, is a more refined speculation. Its first object was number; but the properties of number are more recondite than those of extension and figure. In geometry, the objects of our attention are the very figures themselves; but in algebra, the subjects of our reasonings are represented by symbols, which have no re¬ semblance to the things they represent; hence it is not wonderful that algebra should have a later origin, and that it should have been slower in its progress towards perfection. # Notwithstanding the different origin of geometry and algebra, and their long-continued separate existence, like some chemical substances of different natures, they have a strong affinity; and, when united, their new properties are entirely different from those which belong to each apart. By their union, a new science was created, and new instruments of invention furnished, vastly more power¬ ful than any possessed by the sciences apart. The new views which the labours of \ ieta, Harno, and Descartes opened in geometry and algebra were seized with avidity by the powerful minds of men eager in the pursuit of real knowledge. Accordingly, we nnd in the seventeenth century a whole host of writers on algebra, or algebra combined with geometry. Our limits will not allow us to enter minutely into e claims which each has on the gratitude of posterity. n deed, in pure algebra the new inventions were not so con¬ spicuous as the discoveries made by its applications geometry, and the new theories which were suggested y their union. The refined speculations of Kepler c0”?er" ing the solids formed by the revolutions of cum me figures, the Geometry of Indivisibles by Cavalenus, Arithmetic of Infinites of Wallis, and, above all, tne thod of Fluxions of Newton, and the Differential ancu - tegral Calculus of Leibnitz, are fruits of the happy un , All these were agitated incessantly by their inventors ALGEBRA. \ibra. contemporaries; such men as Barrow, James Gregory, ^/WWren, Cotes, Taylor, Halley, De Moivre, Maclaurin, 425 Stirling, and others, in this country; and abroad by Ro berval, Fermat, Huygens, the two Bernoullis, Herman, Pascal, and many others. It is at this period, then, that our sketch of the history of algebra, at least in Europe, must terminate, because of the great number of writers who have in one way or other elucidated or improved different parts of the subject, either directly, or when treating of collateral theories. We have been as copious as our limits would permit on the early history, because it presents the interesting spec¬ tacle of the progress of a science from an almost imper¬ ceptible beginning, until it has attained a magnitude too great to be fully grasped by the human mind. Of the Indian Algebra. The attention of the learned has, within the last thirty years, been called to a branch of the history of algebra, in no small degree interesting; we mean the cultivation of the science to a considerable extent, and at a remote period, in India. We are indebted, we believe, to Mr Reuben Burrow for some of the earliest notices which reached Europe on this very curious subject. His eagerness to illustrate the history of the mathematical sciences led him to collect oriental manuscripts, some of which, in the Persian lan¬ guage, with partial translations, were bequeathed to his friend Mr Dalby of the Royal Military College, who com¬ municated them to such as took an interest in the subject, about the year 1800. In the year 1813 Mr Edward Strachey published in this country a translation from the Persian of the Bija Gan- nita (or Vija Ganita), a Hindoo treatise on algebra ; and in 1816 Dr John Taylor published at Bombay a translation of Lilawati (or Lilavati), from the Sanscrit original. This last is a treatise on arithmetic and geometry, and both are the production of an oriental algebraist, Bhascara Acharya. Lastly, in 1817 there came out a work entitled Algebra, Arithmetic, and Mensuration, from the Sanscrit of Brahme- gvpta and Bhascara, translated by Henry Thomas Cole- brooke, Esq. This contains four different treatises, origi¬ nally written in Sanscrit verse, viz. the Vija Ganita and Lilavati of Bhascara Acharya, and the Ganitad'haya and Cuttacad hyaya of Brahmegupta. The first two form the preliminary portion of Bhascara’s Course of Astronomy, entitled Sidd'hanta Siromani, and the last two are the twelfth and eighteenth chapters of a similar course of astronomy, entitled Brahma-sidd'hanta. , time when Bhascara wrote is fixed with great pre¬ cision, by his own testimony and other circumstances, to a date that answers to about the year 1150 of the Chris¬ tian era. The works of Brahmegupta are extremely rare, and the age in which he lived is less certain. Mr Davis, an oriental scholar, who first gave the public a correct view of the astronomical computations of the Hindoos, is ° opini°n that he lived in the 7th century; and Dr illiam Hunter, another diligent inquirer into Indian science, assigns the year 628 of the Christian era as about time he flourished. From various arguments, Mr o ebrooke concludes that the age of Brahmegupta was antecedent to the earliest dawn of the culture of the sciences among the Arabians, so that the Hindoos must 'ave possessed algebra before it was known to that nation. rahmegupta’s treatise is not, however, the earliest " °r. hnown to have been written on this subject. Ganessa, a istinguished astronomer and mathematician, and the os eminent scholiast of Bhascara, quotes a passage from much older writer, Arya-Bhatta, specifying algebra under the designation of Vija, and making separate men- Algebra, tion of Luttaca, a problem subservient to the resolution of' indeterminate problems of the first degree. He is under¬ stood by another of Bhascara’s commentators to be at the head of the older writers. They appear to have been able to resolve quadratic equations, by the process of com¬ pleting the square; and hence Mr Colebrooke presumes that the treatise of Arya-Bhatta then extant extended to quadratic equations in the determinate analysis, and to indeterminate equations of the first degree, if not to those of the second likewise, as most probably it did. Considering the proficiency of Arya-Bhatta in astrono¬ mical science, and adverting to the fact of his having written on algebra, and being placed at the head of alge¬ braists when the commentators of extant treatises have occasion to mention the early and original writers on this branch of science, he may be regarded as the great im¬ prover of the analytic art in India, and likely to have been the person by whom it was carried to the pitch it was found to have attained among the Hindoos, and at which it was observed to be nearly stationary through the long lapse of ages which have since passed; the later additions being few and unessential in the writings of Brahmegupta, of Bhascara, and of Jnyanaraja, though they lived at in¬ tervals of centuries from each other. The exact period when Arya-Bhatta lived cannot be determined with certainty; but Mr Colebrooke thinks it probable that this earliest of known Hindoo algebraists wrote as far back as the fifth century of the Christian era, and perhaps earlier. He was therefore nearly as ancient as the Grecian algebraist Diophantus, who is rec¬ koned to have flourished in the time of the emperor Julian, or about a. d. 360. Supposing then the Hindoo and Greek algebraists to be nearly of the same antiquity, it must be conceded in favour of the former, that he was farthest advanced in the science, since he knew how to resolve equations containing several unknown quantities: now it does not appear that Diophantus could do this. He also had a general method for indeterminate equations, of at least the first degree, to a knowledge of which the Grecian algebraist had certainly not attained. It appears from the Hindoo treatises on algebra, that they understood well the arithmetic of surd roots; that they were aware of the infinite quotient resulting from the division of finite quantity by cypher ; that they knew the general resolution of equations of the second degree, and had touched on those of higher denomination, re¬ solving them in particular cases, and in those in which the solution may be effected in the manner of quadratics; that they had found a general solution of indeterminate equations of the first degree, and a method for deriving a multitude of answers to problems of the second degree, when one solution was obtained by trials: now this is as near an approach to a general solution of such problems as was made until the time of Lagi'ange. The Hindoos had also attempted to solve indeterminate equations of higher orders, but, as might be expected, with very little success. We have seen how long it was before algebra was ap¬ plied to geometry in Europe: but the Hindoos not only applied algebra both to astronomy and geometry, but conversely applied geometry to the demonstration of al¬ gebraic rules; and indeed they cultivated algebra much more and with greater success than geometry, as appears by the low state of their knowledge of the one, and the high pitch of their attainments in the other. Mr Colebrooke has instituted a comparison between the Indian algebraist and Diophantus, and found reason to conclude, that in the whole science the latter is very far behind the former. He says, the points in which the 3 H ALGEBRA. ebra. Hindoo algebra appears particularly distinguished from the Greek are, besides a better and more convenient algo¬ rithm, Is#, the management of equations of more than one unknown quantity; 2rf, the resolution of equations of a higher order, in which, if they achieved little, they had at least the merit of the attempt, and anticipated a mo¬ dern discovery in the resolution of biquadratics; 3c?, ge¬ neral methods for the resolution of indeterminate problems of the first and second degrees, in which they went far indeed beyond Diophantus, and anticipated discoveries of modern algebraists; 4#A, the application of algebra to astronomical investigations and geometrical demonstra¬ tion, in which also they hit upon some matters which have been re-invented in modern times. When we consider that algebra made little or no progress among the Arabians, a most ingenious people, and particularly devoted to the study of the sciences, and that centuries elapsed from its first introduction into Europe until it reached any considerable degree of perfection, we may reasonably conjecture, that it may have existed in one shape or other in India long before the time of Arya- Bhatta: indeed, from its close connection with their doc¬ trines of astronomy, it may be supposed to have descend¬ ed from a very remote period, along with that science. The late learned Professor Playfair took a great interest in this curious and interesting subject; and, adopting the opinion of Bailly, the eloquent author of the Astronomie Indienne, he with great ingenuity attempted to prove, in a Memoir on the Astronomy of the Brahmins, that the ob¬ servations on which the Indian astronomy is founded were of great antiquity, indeed more than 3000 years before the Christian era. Again, in a later memoir, On the Trigonometry of the Brahmins, he endeavoured to establish, that the origin of the mathematical sciences in Hindostan must be referred to an equally remote period. The same judicious writer has further considered this most curious subject in a Review of Strachey’s Transla¬ tion of Bija Gannita {Edinburgh Review, No. 42), and again, in a Review of Colebrooke’s work on the Indian algebra, to which we have so frequently adverted {Edin¬ burgh Review, No. 57). This last article, published in 1817, may be supposed to contain the matured opinions of one of the most ardent, able, and we must say most candid, inquirers into the history of Hindoo mathematical science. There is here certainly an abatement of his first confi¬ dence in the opinions of Bailly on the Indian astronomy, and a corresponding caution in his own opinion as to the antiquity of the mathematical sciences. The very remote origin of the Indian astronomy had been strongly ques¬ tioned by many in this country, and also on the Continent; particularly by Laplace, also by Delambre in his His- toire de l’Astronomie Ancienne, tome i. p. 400, &c., and again in Histoire de lAstronomie du Moyen Age, Biscours Preliminaire, p. 18, &c. where he speaks slightingly of their algebra; and in this country, Professor Leslie, in his vei'y learned work on The Philosophy of Arithmetic, p. 225 and 226, calls the Lilavati “ a very poor perform¬ ance, containing merely a few scanty precepts couched in obscure memorial verses.” We shall conclude this slight sketch of the history of Indian algebra with the last recorded sentiments of Professor Playfair on the ma¬ thematical science of India. “ Among many subjects of wonder which the study of these ancient fragments can¬ not fail to suggest, it is not one of the least that algebra has existed in India, and has been cultivated for more than 1200 years, without any signal improvement, or the addition of any material discovery. The works of the ancient teachers of science have been commented on, elucidated, and explained with skill and learning; but no new methods have been invented, nor any new principle Alge introduced. The method of resolving indeterminate pro-^-A 'j blems, that constitute the highest merit of their analytical science, were known to Brahmegupta hardly less accu¬ rately than to Bhascara; and they appear to have been understood even by Arya-Bhatta, more ancient by seve- ral centuries than either. A long series of scholiasts dis¬ play in their annotations great acuteness, intelligence, and judgment; but they never pass far beyond the line drawn by their predecessors, which probably seemed even to those learned and intelligent men as the barrier within which it was to be confined. In India, indeed, every thing seems equally insurmountable, and truth and error are equally assured of permanence in the stations they have once occupied. The politics, the laws, the religion, the science, and the manners, seem all nearly the same as at the remotest period to which history extends. Is it be¬ cause the power which brought about a certain degree of civilisation, and advanced science to a certain height, has either ceased to act, or has met with such a resistance as it is barely able to overcome ? or is it because the disco¬ veries which the Hindoos are in possession of are an in¬ heritance from some more inventive and more ancient people, of whom no memorial remains but some of their attainments in science ? ” Writers on Algebra, with the years in which they wrote or flourished.

NOTATION AND EXPLANATION OF THE SIGNS. 1. In arithmetic there are ten characters, which being variously combined, according to certain rules, serve to denote all magnitudes whatever. But this method of ex¬ pressing quantities, although of the greatest utility in every branch of the mathematics (for we must always have recourse to it in the different applications of that science to practical purposes), is yet found to be in¬ adequate, taken by itself, to the more difficult cases of mathematical investigation ; and it is therefore necessary, in many inquiries concerning the relations of magnitude, to have recourse to that more general mode of notation, and more extensive system of operations, which constitute the science of algebra. In algebra quantities of every kind may be denoted by any characters whatever, but those commonly used are the letters of the alphabet; and as in every mathematical problem there are certain magnitudes given, in order to determine other magnitudes which are unknown, the first letters of the alphabet a, b, c, &c. are used to denote known quantities, while those to be found are represented by v, x, y, &c. the last letters of the alphabet. 2. The sign -j- (plus) denotes that the quantity before which it is placed is to be added to some other quantity. Thus, a-\-b denotes the sum of a and b ; 3-{-5 denotes the sum of 3 and 5, or 8. The sign — (minus) signifies that the quantity before which it is placed is to be subtracted. 1 hus, a — b denotes the excess of a above 6 ; 6—2 is the excess of 6 above 2, or 4. 3. Quantities which have the sign 4- prefixed to them are called positive or affirmative; and such as have the sign — are called negative. 428 ALGEBRA. Algebra. When quantities are considered abstractedly, the terms positive and negative can only mean that such quantities are to be added or subtracted; for as it is impossible to conceive a number less than 0, it follows, that a negative quantity by itself is unintelligible. But, in considering the affections of magnitude, it appears, that in many cases a certain opposition may exist in the nature of quantities. Thus, a person’s property may be considered as a positive quantity, and his debts as a negative quantity. Again, any portion of a line drawn to the right hand may be con¬ sidered as positive, while a portion of the same line, con¬ tinued in the opposite direction, may be taken as nega¬ tive. When no sign is prefixed to a quantity, + is always understood, or the quantity is to be considered as positive. Quantities which have the same sign, either -f- or —, are said to have like signs. Thus, -J- a and + b have like signs, but + a and — c have unlike signs. 4. A quantity which consists of one term, is said to be simple ; but if it consist of several terms, connected by the signs -f- or —, it is then said to be compound. Thus, -f- a and — c are simple quantities ; and 6 -J- c, also a-{-b — d, are compound quantities. 5. To denote the product arising from the multiplica¬ tion of quantities. If they be simple, they are either joined together, as if intended to form a word, or else the quan¬ tities are connected together, with the sign X interposed between every two of them. Thus, ab, or a y.b, denotes the product of a and b; also abc, or ay. b Y,c, denotes the product of a, b, and c: the latter method is used when the quantities to be multiplied are numbers. If some of the quantities to be multiplied be compound, each of them has a line drawn over it called a vinculum, and the tient arising from the division of 12 by 3, or 4; - denotes This tension of that science, ought not to be embarrassed bv Ai the demonstration of its elementary rules. ^ Sect. I.—Fundamental Operations. The primary operations in algebra are the same as in common arithmetic; namely, addition, subtraction, multi¬ plication, and division; and from the various combinations of these four, all the others are derived. Problem I.—To Add Quantities. 10. In addition there may be three cases: the quantities to be added may be like, and have like signs; or they may be like, and have unlike signs; or, lastly, they may be un¬ like. Case 1. To add quantities which are like, and have like signs. Rule. Add together the co-efficients of the quantities, prefix the common sign to the sum, and annex the let¬ ter or letters common to each term. Add together { Examples. + 7a -j- 3a -|- a + 2a C— 2ax Add together 12a* sign x is interposed, as before. Thus, ayc-^-dy e—f de¬ notes that a is to be considered as one quantity, the sum of c and c? as a second, and the difference between e and / as a third; and that these three quantities are to be multiplied into one another. Instead of placing a line over such compound quantities as enter a product, it is now common among mathematical writers to inclose each of them between two parentheses, so that the last product may be otherwise expressed thus, a(c-±-d)(c—■/); or thus, « X 0 + O X (e—/)• 6. A number prefixed to a letter is called a numerical co-efficient, and denotes how often that quantity is to be taken. Thus, 3a signifies that a is to be taken three times. When no number is prefixed, the co-efficient is understood to be unity. 7. The quotient arising from the division of one quantity by another is expressed by placing the dividend above a 12 line, and the divisor below it. Thus, — denotes the quo- Sum, + 13a Sum, — 20a* Case 2. To add quantities which are like, but have unlike signs. Rule. Add the positive co-efficients into one sum, and the negative ones into another; then subtract the least of these sums from the greatest, prefix the sign of the greatest to the remainder, and annex the common let¬ ter or letters as before. Add together {= Examples. 2ax ax 3ax 9aa? Add together ! -f 6a£>-(- — 4o6 -[- 7 9 -f 5 + lab—13 Sum of the pos.

The equality of two quantities is expressed by put¬ ting tbe sign = between them. Thus, a 4- bz=.c — d de¬ notes that the sum of a and b is equal to the excess of c above d. 9. Simple quantities, or the terms of compound quanti¬ ties, are said to be like, which consist of the same letter or letters. Thus, -\-ab and —bab are like quantities, but 4-a6 and -\-abb are unlike. There are some other characters, which will be explained when we have occasion to use them; and in what follows we shall suppose that the operations of common arithme¬ tic are sufficiently understood; for algebra, being an ex- baa 0 4- §xx Sum, 0 Case 3. To add unlike quantities. Rule. Put down the quantities, one after another, in any order, with their signs and co-efficients prefixed. Examples. 2a 3b —4c ax-\-2ay bb—3bz Sum, ax-\-2ay-\-bb—3bz Sum, 2a 4- 3b—4c Pros. II.—To Subtract Quantities. 11. General Rule. Change the signs of the quantities to be subtracted, or suppose them changed, and then add them to the other quantities, agreeably to the rules of addition. < 1 4 ALGEBRA. Examples. From 5a—126 From 6x— % -f 3 Subtract 2a— 56 Subtract 2a; + %—2 429 Remainder 4a;—17y+5 aa—ax—yy 66—by-\-zz Remainder 3a— 76 bxy—2-f- 8a;— y Sxy—8— 8a;— 2a;y4-6 + 16a;+2y aa—ax—yy—bb-\-by—zz The reason of the rule for subtraction may be explained thus. Let it be required to subtract 2p—2>q from m + n. If we subtract 2p from m-\-n, there will remain m + n—2p; but if we are to subtract 2p—3+a66 aa—ab -f ac -f aa6—a66-f 666 -fa6 —66+6c ~ " —ac + be—cc (ma * *+666 aa * * —66+26c—cc. The reason of the ru^es for the multiplication of quan- 1 ies may be explained in the following manner:—Let it t0 multiply a—6 by c—d; because multipli- „ ,?n 18 a rppcated addition of the multiplicand as often e multiplier contains unity; therefore, a—6 is to be 13. General Rule for the Signs. If the signs of the divisor and dividend be like, the sign of the quotient is + ; but if they be unlike, the sign of the quotient is —. This rule is easily derived from the general rule for the signs in multiplication, by considering that the. quotient must be such a quantity as, when multiplied by the divisor, shall produce the dividend, with its proper sign. The quotient arising from the division of one quantity by another may be expressed by placing the dividend above a line and the divisor below it (sect. 25); but it may also be often expressed in a more simple manner by the following rules. Case 1. When the divisor is simple, and a factor of every term of the dividend. Rule. Divide the co-efficient of each term of the dividend by the co-efficient of the divisor, and expunge out of each term the letter or letters in the divisor: the result is the quotient. Ex. 1. Divide 12a6c by Sac. From the method of notation, the quotient may be ex¬ pressed thus, ^~a^c; but the same quotient, by the rule 3oc just given, is more simply expressed thus, 46. Ex. 2. Divide \Qa5xy—28a2.cz2 + 4a2a;3 by 4a2.r. The quotient is 4ay—lz‘2-\-x2. If the divisor and dividend be powers of the same quan- 430 ALGEBRA. Algebra, tity, the division will evidently be performed by subtract- ing the exponent of the divisor from that of the dividend. Thus a5, divided by «3, has for a quotient a5"3—a2. Case 2. When the divisor is simple, but not a factor of the dividend. Rule. The quotient is expressed by a fraction, of which the numerator is the dividend, and the denominator the divisor. Thus the quotient of 3«62, divided by 2mbc, is the frac- It will sometimes happen that the quotient found thus may be reduced to a more simple form, as shall be ex¬ plained when we come to treat of fractions. Case 3. When the divisor is compound. Rule 1. The terms of this dividend are to be arranged ac¬ cording to the powers of some one of its letters, and those of the divisor according to the powers of the same letter. 2. The first term of the dividend is to be divided by the first term of the divisor, observing the general rule for the signs; and this quotient, being set down for a part of the quotient wanted, is to be multiplied by the whole divisor, and the product subtracted from the dividend. If nothing remain, the division is finished; but if there be a remainder, it is to be taken for a new dividend. 3. The first term of the new dividend is next to be divid¬ ed by the first term of the dividend, as before, and the quotient joined to the part already found, with its pro¬ per sign. The whole divisor is also to be multiplied by this part of the quotient, and the product subtracted from the new dividend; and thus the operation is to be carried on till there be no remainder, or till it appear that there will always be a remainder. To illustrate this rule, let it be required to divide 8«2 -f 2ab—1562 by 2a+ 36, the operation will stand thus: 2a+36)8a2 + 2ab—1562(4a—56 8a2 + 12a6 —10a6—1562 —10a6—1562 Here the terms of the divisor and dividend are arranged according to the powers of the quantity a. We now di¬ vide 8a2, the first term of the dividend, by 2a the first term of the divisor; and thus get 4a for the first term of the quotient. We next multiply the divisor by 4a, and subtract the product 8a2 +12a6 from the dividend; we get— 10a6— 1562 for a new dividend. By proceeding in all respects as before, we find — 56 for the second term of the quotient, and no remainder: the operation is therefore finished, and the whole quotient is 4o—56. The following examples will also serve to illustrate the manner of applying the rule. Ex. 1. 3a—6)3a3— 12a2—a26 + 10a6—262(a2—4a+26 3a3 —a26 —12a2 +10a6 —12a2 + 4a6 + 606—262 + 6a6—262 Ex. 2. a+6)a3 + 63(a2—ab +1^ a3 + a26 —a26 + 63 —a26—air + air + 63 + 062 + 63 Ex. 3. a3—63)a6—6fi(a3 + 63 a6—aPlP + a36-3—66 + a363—6s Ex. 4. 1 tf)l (l + £ + 4'2 + , &C. 1 X A bra. + a: + £ *2 + a?2 + a?2—Xs + a;3. 14. Sometimes, as in this last example, the quotient will never terminate: in such a case it may either be consid¬ ered as an infinite series, the law according to which the terms are formed being in general sufficiently obvious; or the quotient may be completed as in arithmetical divi¬ sion, by annexing to it a fraction, the numerator of which is the remainder, and denominator the divisor. Thus the quotient in last example may stand thus: l+tf+^+X—.. The reason of the rule for division is sufficiently mani¬ fest. For, in the course of the operation, all the terms of the quotient obtained by it are multiplied by all the terms of the divisor, and the products successively subtracted from the dividend, till nothing remain; that therefore must evidently be the true quotient. Sect. II.—Oe Fractions. 15. In the operation of division, the divisor may be sometimes less than the dividend, or may not be contain¬ ed in it an exact number of times : in either case the quo¬ tient is expressed by means of a fraction. There can be no difficulty, however, in estimating the magnitude of such a quotient; if, for example, it were the fraction f, we may consider it as denoting either that some unit is divided into 7 equal parts, and that 5 of these are taken, or that 5 times the same unit is divided into 7 equal parts, and one of them taken. 16. In any fraction the upper number, or the dividend, is called the numerator> and the lower number or divisor a is called the denominator. Thus, in the fraction « 15 the numerator, and 6 the denominator. 17. If the numerator be less than the denominator> such a fraction is called a proper fraction; but if the nu¬ merator be either equal to, or greater than the denomina¬ tor, it is called an improper fraction; and if a quantity oe i ALGEBRA. u Up of an integer and a fraction, it is called a mixed which divided by—2x is a—x)a?—^(a + x * J d % n • d - CL -4- X ^ quantity. Thus, — is a proper fraction; also X I tix are both improper fractions ; and £-f- is a mixed quantity. ^ 431 Algebra. 18. The reciprocal of a fraction is another fraction, having its numerator and denominator respectively equal to the denominator and numerator of the former. Thus, - is the reciprocal of the fraction 19. The following proposition is the foundation of the operations relating to fractions. If the numerator and denominator of a fraction be either both multiplied or both divided by the same quan¬ tity, the value of that fraction is the same as before. For, let any fraction -pf=-cl then, because c is the quo¬ tient arising from the division of b by a, it follows that and multiplying both by any quantity n, we have nbzznac: let these equals be both divided by the same quantity na, and the quotients will be equal, that is, ~—c=-; hence the truth of the proposition is manifest. * * Hence it appears that a—x is the greatest common mea¬ sure required. ■Ex. 2. Required the greatest common measure of 8a2b?—and 9a4b—9a3b?3a2b3—3ab4. It is evident, from inspection, that & is a simple divisor of both quantities; it will therefore be a factor of the common measure required. Let the simple divisors be now left out of each quantity, and they are reduced to 4a2— Bab -j- ^ and 3a3—3a2b -(- ad1—Id; but as the second of these is to be divided by the first, it must be multiplied by 4 to make the division succeed, and the operation will stand thus: \a2—Bab+W) 12a3—\2a% + \ald—Ab\3a 12a3—XBcfib -f- Sat2 no, a From this proposition, it is obvious that a fraction may be very differently expressed, without changing its value, and that any integer may be reduced to the form of a fraction, by placing the product arising from its multipli¬ cation by any assumed quantity as the numerator, and the assumed quantity as the denominator of the fraction. It also appears that a fraction very complex in its form may often be reduced to another of the same value, but more simple, by finding a quantity which will divide both the numerator and denominator, without leaving a remainder. Such a common measure, or common divisor, may be either simple or compound; if it be simple, it is readily found by inspection, but if it be compound, it may be found as in the following problem. -f- 3cdb -f- aid—\b3. This remainder is to be divided by b, and the new divi¬ dend multiplied by 3, to make the division again succeed, and the work will stand thus: 3a2 + ab—W)l2d?—\Bab+ 3^(4 12a2-}- 4a£—16Z*2 —19a6-j-im This remainder is to be divided by — \9b, which being done, and the last divisor taken as a dividend as before, the rest of the opei'ation will be as follows: a—b)3a2-\- ab—462(3a-|-46 3a2—3ab 20. Prob. I.— To find the greatest common Measure of two Quantities. Rule 1. Range the quantities according to the power of some one of the letters, as taught in division, leaving out the simple divisors of each quantity. 2. Divide that quantity which is of most dimensions by the other one, and if there be a remainder, divide it by its greatest simple divisor; and then divide the last compound divisor by the resulting quantity, and if any thing yet remain, divide it also by its greatest simple divisor, and the last compound divisor by the result¬ ing quantity. Proceed in this way till nothing remain, and the last divisor shall be the common measure re¬ quired. Nate. It will sometimes be necessary to multiply the di¬ vidends by simple quantities in order to make the divi¬ sions succeed. Ex. 1. Required the greatest common measure of the quantities a2#—x4 and a3—2d2x -(- ax2. The simple di¬ visor # being taken out of the former of these quantities, ‘ind a out of the latter, they are reduced to a2—x2, and a fz-j-'X3; and as the quantity a rises to the same di- inensions in both, we may take either of them as the first 1 lvlsor.i let us take that which consists of several terms, aud tlie operation will stand thus: a2—x3)a2—2a* -{- *2( 1 a2—x2 —2a* -j- 2*2 remainder, -{- 4a&— -}- 4a&—ild * # from which it appears that the compound divisor sought is a—b, and remarking that the quantities proposed have also a simple divisor b, the greatest common measure which is required will be b (a—b). 21. The reason of the rule given in this problem maybe deduced from the following considerations. 1. If two quantities have a compound divisor common to both, and they be either multiplied or divided by any simple quantities, the results will each have the same compound divisor. Thus the quantities p(a—*) and q (a—*) have the common divisor a—*, and the quantities n p (a—*), r q (a—*) have each the very same divisor. 2. In the operation of division, whatever quantity mea¬ sures both the divisor and dividend, the same will also measure the remainder. For let * be such a quantity, then the divisor and dividend may be represented by ax and bx; let q be the quotient, and the remainder will evidently be bx—qax, which is evidently divisible by *. 3. Whatever quantity measures both the divisor and re¬ mainder, the same will also measure the dividend; for, let the divisor be a*, and the remainder r*, then q, denot¬ ing the quotient, the dividend will be a^*+r*, which, as well as the divisor and dividend, is divisible by *. Let us apply these observations to the last example. From the first observation, the reason for leaving out the simple quantities in the course of the operation, as well as 432 ALGEBRA. Algebra, for multiplying by certain other quantities, to make the 1 ^divisions succeed, is obvious; and from the second obser¬ vation it appears, that whatever quantity measures 4a2— bab+tf, and 12a3—12«26 + 4«62—46s, the same must measure Sa^ + oi2—463, the first remainder, as also—19a6 -|- lOaS2, the second remainder; but the only compound divisor which this last quantity can have is a—b, which is also found to be a divisor of 3a2 -j- a6—4&2, or of ‘ia~b -J- al?—463. The first remainder, therefore, by the third ob¬ servation, a—b, must also be a divisor of 12a2—\bub 362, or of 4a2—bab + fb, the first divisor, and therefore also it must be a divisor of 12a3—12a26-|-4aJ2—4S3, the first dividend; so that a—b is the greatest common measure, as was required. 22.

Thus, -^r denotes apfr-i , a2 _ the same thing as p- or as arb-'cr3; also may be otherwise expressed thus, a2(x—l)-3. Of Involution. 32. Involution is the method of finding any power of any assigned quantity, whether it be simple or compound. hence its rules are easily derived from the operation of multiplication. Case 1. When the quantity is simple. Buie. Multiply the exponents of the letters by the index of the power required, and raise the co-efficient to the same power. Note. If the sign of the quantity be +, all its powers will be positive ; but if it be —, then all its powers whose exponents are even numbers are positive, and all its powers whose exponents are odd numbers are negative. Ex. 1. Required the cube, or third power, of 2«2^ (2a2x):i=2 x 2 x 2a2x:ixlx3=Sar>x\ the answer. Ex. 2. Required the fifth power of —Saftc3. (—3d2x‘if——2i3a10*15, the answer. Ex. 3.

Besides the method of finding the powers of a compound quantity by multiplication, which we have just now explained, there is another more general, as well as more expeditious, by which a quantity may be raised to any power whatever without the trouble of finding any of the inferior powers, namely, by means of what is com¬ monly called the binomial theorem. This theorem may be expressed as follows: Let a—* be a binomial quantity, which is to be raised to any power denoted by the num¬ ber «, then (a-f *)n=r n n ^ . w(w" '”-1* -f- l + Ta 1 • 2 i>«- -2^2 n(n—l)(w—2) 1 • 2 a’1-3*3 + l)(w—2)Q—3)^^ 2) Q-3) (n-Afan^ +1-2-3-4-5 This series will always terminate when n is any whole po¬ sitive number, by reason of some one of the factors n—l, n—2, &c. becoming — 0; but if n be either a negative or fractional number, the series will consist of an infinite number of terms. As, however, we mean to treat in this section only of the powers of quantities when their expo¬ nents are whole positive numbers, we shall make no fur¬ ther remarks upon any other: we shall afterwards give a demonstration of the theorem, and show its application to fractional and negative powers, in treating of infinite series. The «th .power of a—* will not differ from the same power of a + *, but in the signs of the terms which com- 7% pose it, for it will stand thus: (a—*)Mzzan—-^an~lx n (re—1) 81&Y’ Case 2. When the quantity is compound. Rule. The powers must be found by a continual multipli¬ cation of the quantity by itself. Ex.

Of Evolution. 35. Evolution is the reverse of involution, or it is the method of finding the root of any quantity, whether sim¬ ple or compound, which is considered as a power of that root: hence it follows that its operations, generally speak¬ ing, must be the reverse of those of involution. To denote that the root of any quantity is to be taken, the sign */ (called the radical sign) is placed before it, and a small number placed over the sign to express the denomination of the root. Thus denotes the square 3 - . 4 - . root of «, if a its cube root, if a its fourth root, and in ge¬ neral, fa its nth root. The number placed over the radi¬ cal sign is called the index or exponent of the root, and is usually omitted in expressing the square root: thus, either fa or fa denotes the square root of a. Case 1. When roots of simple quantities are to be found. Rule. Divide the exponents of the letters by the index of the root required, and prefix the root of the numeral co-efficient; the result will be the! root required. Note 1. The root of any positive quantity may be either positive or negative, if the index of the root be an even number; but if it be an odd number, the root can be positive only. 2xa- 2. The root of a negative quantity is also negative when X the index of the root is an odd number. 3. But if the quantity be negative, and the index of the root even, then no root can be assigned. Ex. 1. Required the square root of Sfioftr4. Here the index of the root is 2, and the root of the co-efficient 6, therefore VSGaWzz+Gax2 or fSGaW ——■Sax2; for either of these quantities, when multiplied by itself, produces 36o2a;4; so that the root required is where the sign z±z denotes that the quantity to which it is prefixed may be considered either as positive °r negative. is therefore said to be impossible, and may be expressed Algebra, thus: f—a2. The root of a fraction is found by extracting that root out of both numerator and denominator. Thus the square r 4a2x4 . 2a,x2 r00t0iWf1S3h? Case 2. When the quantity of which the root is to be ex¬ tracted is compound. 36. I. To extract the square root. Range the terms of the quantity according to the pow¬ ers of the letters, as in division. Find the square root of the first term for the first part of the root sought, subtract its square from the given quantity, and divide the remainder by double the part al¬ ready found, and the quotient is the second term of the root. Add the second part to double the first, and multiply their sum by the second part; subtract the product from the remainder, and if nothing remain, the square root is obtained. But if there is a remainder, it must be divided by the double of the parts already found, and the quotient will give the third term of the root, and so on. Ex. 1. Required the square root of a2^-2ax-\-a?, a- -j- 2ax -j- a:2(« -}- x, the root required. 2a-\-x\-f2ax-\-xi y.x)-\-2ax-irx7l Ex. 2.

T As an illustration of the common rule for extracting the h it be required to extract the square root of—a2, it will square root of any proposed number, we shall suppose that inunediately appear that no such root can be assigned; for the root of 59049 is required. 1 can neither be -(-a nor —a, seeing that each of these Accordingly we have (a-\-b-\-c)2-=z59049, and from quantities, when squared, produces -}-a2: the root required hence we are to find the values of a, b, and c. Ex. 2. Required the cube root of 125a%:9. Here the index of the root is 3, and the root of the co¬ efficient 5, therefore f 125a6x9= 5a2*3, the root required; unu in like manner the cube root of be —5a2x3. 1 436 Algebra.

Add together three times the square of the part of the root already found, three times the product of that part and the second part of the root, and the square of the se¬ cond part; multiply the sum by the second part, and sub¬ tract the product from the first remainder, and if nothing remain, the root is obtained; but if there is a remainder, it must be divided by three times the square of the sum of the parts already found, and the quotient is a third term of the root, and so on, till the whole root is obtained.

II. To extract the cube root. Range the terms of the quantity according to the pow¬ ers of some one of the letters. Find the root of the first term, for the first part of the the reason for the common rule for extracting the cube root in numbers. Let it be required to find the cube root of 13312053, where the root will evidently consist of three figures ; let us suppose it to be represented by a-f b + c, and the operation for finding the numerical values of these quantities may stand as follows. 13312053(200=a a3= 8000000 30=5 7=c 3a2= 120000 3a5= 18000 52= 900 3a2+ 305 + 52= 138900 3(a+5)2= 158700 3(a + 5)c= 4830 c2= 49 5312053 237 the root required. 4167000=(3a2+3a5+52)5 1145053 3(a + 5)2 + 3(a + 5)c+^= 163579 1145053= [3(a + 5)2+3(a + 5)c+c2]^ The operation as performed by the common rule (see Arithmetic) will stand thus: 13312053(237 the root required. 8 12.. 18 1389 1587. 383 49 5312 4167 1145053 Involve the first member of the root to a power less by unity than the number that denominates the root re¬ quired, and multiply the power that arises by the num¬ ber itself; divide the second term of the given quan¬ tity by the product, and the quotient shall give the second member of the root required. Find the remaining members of theroot in the same manner by considering those already found as making one term. Ex. Required the cube rootof a^ + fiar*—40r3+96a;—64 xG + 6a^—40a*5+96x—64(t2+2x—4 («2)3=a^! 3xi)6x5 163579 1145053 38. III. To extract any other root. Eule. Range the quantity of which the root is to be found, according to the powers of its letters, and extract the root of the first term, and that shall be the first member of the root required. (#2 + 2a;)3=;r6 + 6;r5+ ^a^ + S-r3 3a?4+ , &c.)—12a4 (a? + 2a:—4)3=a;G + Gx5—40ar3+96a?—64 * ALGEBRA. 437 , u In this example, the cube root of x6, or x2, is the first vvl'member of the root; and to find a second member, the first is raised to the power next lower, or to the second power, and also multiplied by 3, the index of the root required. Thus we get 3a?4 for a divisor, by which the second term 6a^ being divided, we find 2a? for the second member of the root. We must now consider a? + 2a? as forming one term: accordingly, having subtracted its cube from the quantity of which the root is sought, we have —12a?4—, &c. for a new dividend ; and having also raised a^-|-2a? to the second power, and multiplied the result by 3, we find &c. for a divisor. (As it is only the terms which contain the highest powers of the dividend and divisor that we have occasion for, the remaining terms are ex¬ pressed by &c.) Having divided —12a?4 by Sad, we find —4) for the third term of the root; and because it appears that a?-f 2a:—4, when raised to the third power, gives a result the very same with the proposed power, we conclude ^4-2a:—4 to be the root sought. 39. In the preceding examples, the quantities whose roots were to be found have been all such as could have their roots expressed by a finite number of terms ; but it will frequently happen that the root cannot be otherwise assigned than by a series consisting of an infinite number of terms. The preceding rules, however, will serve to de¬ termine any number of terms of the series. Thus, the square root of will be found to be a-|- + CjCc ttt-;—&c., and the cube root of a3-f.a^ will loo5 12oa7 1 staM to, ^ - M+ Si* - But as the extraction of roots in the form of series can be more easily performed by other methods, we shall refer the reader to sect. 19, which treats of series, where this subject is resumed. Sect. IV.—Of Surds. both to the power n, am — 6n, and further, raising both to Algebra, the power c, we get ar—fr*: let the root cn be now taken, and we find a™ ~b — 41. Pros. I.— To Reduce a Rational Quantity to the form of a Surd of any given denomination. Rule. Reduce the exponent of the quantity to the form of a fraction of the same denomination as the uiven surd. & Ex. I. Reduce a2 to the form of the cube root. Here the exponent 2 must be reduced to the form of a fraction having 3 for a denominator, which will be the frac- 6 3 tion |; therefore drz=a?—/fd\ Ex. 2. Reduce 5 to the form of the cube root, and 3a52 to the form of the square root. First, 5r=53 z= fax 5x5=^125, And Sali2 = 3%a%b$ = (32a2b4)i= V'Oa-b4. 42. Prob. II.— To Reduce Surds of different denominations to others of the same value, and of the same denomina¬ tion. Rule. Reduce the fractional exponents to others of the same value, and having the same common denominator. 3 — 1 (2 Ex. 1. Reduce a and ora2 and b^ to other equivalent surds of the same denomination. The exponents §, when reduced to a common deno¬ minator, are § and 4-; therefore the surds required are 3:174 6 6 a6 and W, or fa? and fb4. Ex. 2. Reduce 32 and 23 to surds of the same denomi¬ nation. 40. It has been already observed (35), that the root of any proposed quantity is found by dividing the exponent of the quantity by the index of the root; and the rule has been illustrated by suitable examples, in all which, how¬ ever, the quotient expressing the exponent of the result is a whole number; but there may be cases in which the quotient is a fraction. Thus, if the cube root of a2 were required, it might be expressed, agreeably to the me¬ thod of notation already explained, either thus, fa2, or thus, a3. Quantities which have fractional exponents are called surds, or imperfect powers, and are said to be irrational, ln opposition to others with integral exponents, which are called rational. Surds may be denoted by means of the radical sign, but a will be often more convenient to use the notation of fractional exponents. The following exaipples will show how they may be expressed either way. f(i — a3, f ^ab2 — 2ba2, fcdb2 — a4ZA, */a2+V- (a2 _|_ £2)i f dfb f (a—b)2 = (a—bf5, 4. 4 Vab = («-f ^)2 cr~2b~2. The operations concerning surds depend on the follow- 'ng principle: If the numerator and denominator of a lactional exponent be either both multiplied or both ('vu e(4 bJ the same quantity, the value of the power is » rn cm m ic same. Thus, an zz acn. For let anz:b, then raising The new exponents are 4 and % therefore we have X 3. 6 6 1 2 6 6 32z=.36z=.f3iA-=. f21, and 23 = 2^z=:f22 =f4. . J- l And in the same way the surds Am, B”, are reduced mn mn to these two, fAn and fV>m. 43. Prob. III.— To Reduce Surds to their most simple terms. Rule. Reduce the surd into two factors, so that one of them may be a complete power, having its exponent divisible by the index of the surd. Extract the root of that power, and place it before the remaining quantities, with the proper radical sign between them. Ex. 1. Reduce f4<8 to its most simple terms. The number 48 may be resolved into the two factors 16 and 3, of which the first is a complete square; there¬ fore v/48=(42 X 3)2—4 x 32=4^/3. 3 Ex. 2. Reduce f98a4x, and f2^cdx + 40a3a?2, each to its most simple terms. First, v/98a4r = (7%4 x 2a?)2 = la2 x (2x)2 = 7a2f2x. Also f2±a3x + dOa3*2 = (23a3 (3a? + bx2))*=:2af3x+bx?. 44. Prob. IV.— To Add and Subtract Surds. Rule. If the surds are of different denominations, reduce them to others of the same denomination, by prob. 2, A L G E and then reduce them to their simplest terms by last problem. Then, if the surd part be the same in them all, annex it to the sum or difference of the rational parts, with the sign of multiplication, and it will give the sum or difference required. But if the surd part be not the same in all the quantities, they can only be added or subtracted by placing the signs + or — be¬ tween them. Ex. 1. Required the sum of V27 and a/48. _ By prob. 3 we find ^27=3 A/3_and \/48=4 V'S, therefore \/27-l~ \/48~3 a/3-{-4 \/3=7 a/3. O Ex. 2.

Surds are involved or evolved in the same manner asV any other quantities, namely, by multiplying or dividing their exponents by the index of the power or root re^ 3_ 2 quired. Thus, the square of 3 a/3 is 3 x 3 x (3)3=; 3 _ i - 9 */ 9. The wth power of xm is xm. The cube root 1 _ 1 A 6 _ _L 1 of -a/2 is ^(S)6 a/2 and the «th root of x™ is r>‘\ 8 2 2 ’ 47. If* a compound quantity involve one or more surds, its powers may be found by multiplication. Thus, the square of 3 + a/5 is found as follows : 3 + ^5 3 +a^5 ebra. /x. 9 + 3a/5 + 3a/5 + 5 9-}-6A/5 + 5r=144-6A/5, the square required. 48. The square root of a binomial or residual surd, A + B, orA—B, may be found thus. Find D—a/A2—B2, .v/a+b=«/ then Ride. If they are surds of the same rational quantity, add or subtract their exponents. But if they are surds of different rational quantities, let them be brought to others of the same denomination, by prob. 2. Then, by multiplying or dividing these rational quantities, their product or quotient may be set and • D 2 2 Thus the square root_©f is 1-{-a/7; and the square root of 3 — a/8 is a/2— 1. With respect to the extraction of the cube or any higher root, no general rule can be given. Note. If the surds have any rational co-efficients, their product or quotient must be prefixed. Sect. V.—Of Proportion. Z*2 49. In comparing together any two quantities of the same kind in respect of magnitude, we may consider how much the one is greater than the other, or else how many times the one contains either the whole or some part of the other; or, which is the same thing, we may consider either what is the difference between the quantities, or what is the quotient arising from the division of the one quantity by the other: the former of these is called their arithmetical ratio, and the latter their geometrical ratio. These denominations, however, have been assumed arbi¬ trarily, and have little or no connection with the relations they are intended to express. I. Of Arithmetical Proportion. 50. When of four quantities the difference between the first and second is equal to the difference between the third and fourth, the quantities are called arithmetical pro¬ portionals. Such, for example, are the numbers 2, 5, 9,12; and, in general, the quantities a, a^-d, b, b-\-d. If the two middle terms are equal, the quantities constitute an arithmetical progression. 51. The principal property of four arithmetical propor¬ tionals is this :—If four quantities be arithmetically pro¬ portional, the sum of the extreme terms is equal to the sum of the means. Let the quantities be a,a^-d, b, Z>-}-«» where d is the difference between the first and second, and also between the third and fourth, the sum of the ex¬ tremes is a-}-Z»4-d ; and so on. Hence if z denote the last term, n the number of terms, and a and d express the first term and common difference, we have z~a-\‘(n—~V) d. 2. The sum of the first and last term is equal to the sum of any two terms at the same distance from them. Thus, suppose the number of terms to be 7, then the last term is a-f 6(/, and the sum of the first and last 2a^-Qd; but the same is also the sum of the second and last but one, of the third and last but two, and so on till we come to the middle term, which, because it is equally distant from the extremes, must be added to itself. From the last-mentioned property we derive a rule for finding the sum of all the terms of the series. For if the sum of the first and last be taken, as also the sum of the second and last but one, of the third and last but two, and so on along the series till we come to the sum of the last and first terms, it is evident that we shall have as many sums as there are terms, and each equal to the sum of the first and last terms ; but the aggregate of those sums is equal to all the terms of the series taken twice, there¬ fore the sum of the first and last term, taken as often as there are terms, is equal to twice the sum of all the terms ; so that if s denote that sum, we have 2s—n(a^-z)y and n. . s=-(a+z). Hence the sum of the odd numbers 1, 3, 5, 7, 9, &c. continued to n terms, is equal to the square of the num¬ ber of terms. For in this case 1, d=2, z=z I -J- (n—1) d — 2w—1, therefore X 2razrw2. II. Of Geometrical Proportion. 54. When, of four quantities, the quotient arising from the division of the first by the second is equal to that arising from the division of the third by the fourth, these quantities are said to be in geometrical proportion, or are called simply proportionals. Thus, 12, 4, 15, 5, are four numbers in geometrical proportion; and, in general, na, a> nb> b, may express any four proportionals, for , nb also—— na , ——n, and a To denote that any four quantities a, b, c, d, are pro¬ portionals, it is common to place them thus, a : b :: c: d; or thus, a : b—c ; d; which notation, when expressed in words, is read thus, a is to £ as c to d, or the ratio of a to ^ 'Le(lual t° the ratio of c to d. Ihe first and third terms of a proportion are called the •antecedents, and the second and fourth the consequents. When the two middle terms of a proportion are the Algebra, same, the remaining terms, and that quantity, constitute three geometrical proportionals; such as 4, 6, 9, and in general n a, a, -. In this case the middle quantity is called a mean proportional between the other two. 55. The principal properties of four proportionals are the following: 1. If four quantities be proportionals, the product of the extremes is equal to the product of the means. Let a, b, c, d, be four quantities, such that a -. b :: c : d; then, from the nature of proportionals, |rrJ; let these equal quotients be multiplied by b d, and we have or ad zr be. Hence it follows, that when three quantities are proportional, the product of the extremes is equal to the square of the middle term. It also appears, that if any three of four proportionals be given, the remaining one may be found. Thus, let a, b, c, the first three, be given, and let it be required to find x, the fourth term; because a : b :: c '. x, ax —be, and dividing by a,xz=. —. This conclusion may be considered as a demonstration of what is called the rule of three in arithmetic. 2. If four quantities be such, that the product of two of them is equal to the product of the other two, these quan¬ tities are proportionals. Let a, b, c, d, be the quantities, which are such that ad z=. be ; if these equals be divided by bd, then ^ hence, from the definition given of proportionals (sect. 54), a \ b :x c '. d. From this property of pro¬ portionals it appears, that if three quantities be such that the square of one of them is equal to the product of the other two, these quantities are three proportionals. If four quantities are proportional, that is, if « : 5 :: c : e?, then will each of the following combinations or arrange¬ ments of the quantities be also four proportionals. 1a'£, By inversion, b : a :: d : c. 2d, By alternation, a : c :: b : d. Note.—The quantities in the second case must be all of the same kind. 3d, By composition, a-\-b : a :: c + d: c, or, a-\-b : b :: c-\-d : d. 4^/i, By division, a—b: awe—d\c, or, a—b :b w c—d: d. bih, By mixing, a-\-b : a—b w cJ^-d '. c — d. 6th, By taking any equimultiples of the antecedents, and also any equimultiples of the consequents, na : pb w nc : pd. Hth, Or, by taking any parts of the antecedents and con- a b c d sequents, That the preceding combinations of the quantities a, b, c, d, are proportionals, may be readily proved, by taking the products of the extremes and means; for from each of them we derive this conclusion, that ad — be, which is known to be true, from the original assumption of the quantities. If four quantities be proportional, and also other four, the product of the corresponding terms will be propor¬ tional. Let a : b :: c id, And e : fw g : h; Then ae : bfi: eg: dh. 440 ALGEBRA. Algebra. For ad = be, and eh — fg (sect. 55), therefore, multi- plying together these equal quantities, adeh — befg, or ae x dh = bf y. eg; therefore, by the second property (sect. 55), ae :bf eg : dh. Hence it follows, that if there be any number of pro¬ portions whatever, the products of the corresponding terms will still be proportional. 56. If a series of quantities be so related to each other, that the quotient arising from the division of any term by that which follows it is always the same quantity, these are said to be in continued geometrical proportion; such are the numbers 2, 4, 8, 16, 32, &c. also yg-, &c. and in general, a series of such quantities may be repre¬ sented thus, a, ar, ar2, aifi, ar^, ar>, &c. Here a is the first term, and r the quotient of any two adjoining terms, which is also called the common ratio. By inspecting this series, we find that it has the fol¬ lowing properties: 1. The last term is equal to the first, multiplied by the common ratio raised to a power, the index of which is one less than the number of terms. Therefore, if z denote the last term, and n the number of terms, 2? = arn^. 2. The product of the first and last term is equal to the product of any two terms equally distant from them: thus, supposing ar5 the last term, it is evident that a x ar* z= ar y, ar* ■= aiP X ar3, &c. The sum of n terms of a geometrical series may be found thus: Let s =. a + ar ar2 ar3...-!- arn~l, Then rs — ar -j- ar2 -j- air3...-^- arn-1-|-ar”. Subtract, rs — s — arn — a ; That is, (r — 1) s = a(rn —- 1). rn — 1 Hence s = r a. r — I Sect. YI.—Of the Resolution of Equations involv¬ ing one Unknown Quantity. 57. The general object of algebraic investigation is to discover certain unknown quantities, by comparing them with other quantities which are given, or supposed to be known. The relation between the known and unknown quantities is either that of equality, or else such as may be reduced to equality; and a proposition which affirms that certain combinations of quantities are equal to one another is called an equation. Such are the following:— x x 2k 2+ 3 - 2x 3^ — xy. The first of these equations expresses the relation between an unknown quantity x and certain known numbers; and the second expresses the relation which the two indefinite quantities x and y have to each other. 58. When a quantity stands alone on one side of an equation, the terms on the other side are said to be a value of that quantity. Thus, in the equation x — ay + 5 —c, the quantity x stands alone on one side, and ay-{-b — c is its value. The conditions of a problem may be such as to require several equations and symbols of unknown quantities for their complete expression. These, however, by rules here¬ after to be explained, may be reduced to one equation, involving only one unknown quantity and its powers, be¬ sides the known quantities ; and the method of expressing that quantity by means of the known quantities consti¬ tutes the theory of equations, one of the most important as well as most intricate branches of algebraic analysis. 59. An equation is said to be resolved when the unknown quantity is made to stand alone on one side, and only A known quantities on the other side ; and the value of the ^ unknown quantity is called a root of the equation. 60. Equations containing only one unknown quantity and its powers, are divided into different orders, according to the highest power of that quantity contained in any one of its terms. The equation, however, is supposed to be reduced to such a form that the unknown quantity is found only in the numerators of the terms, and that the exponents of its powers are expressed by positive integers. 61. If an equation contains only the first power of the unknown quantity, it is called a simple equation, or an equation of the first order. Such is ax-\-b — c, where x denotes an unknown, and a, b, c, known quantities. If the equation contains the second power of the un¬ known quantity, it is said to be of the second degree, or is called a quadratic equation; such is -f 3a; — 12, and in general ax?-{-bx = c. If it contains the third power of the unknown quantity, it is of the third degree, or is a cubic equation; such are x? — 2^ + 4*= 10, and aoP + bx2 -\-ca — d; and so on with respect to equations of the higher orders. A simple equation is sometimes said to be linear, or of one dimension. In like manner, quadratic equations are said to be of two dimensions, and cubic equations of three dimensions. 62. When in the course of an algebraic investigation we arrive at an equation involving only one unknown quantity, that quantity will often be so entangled in the different terms as to render several previous reductions necessary before the equation can be expressed under its characteristic form, so as to be resolved by the rules which belong to that form. These reductions depend upon the operations which have been explained in the former part of this treatise, and the application of a few self-evident principles, name¬ ly, that if equal quantities be added to or subtracted from equal quantities, the sums or remainders will be equal; if equal quantities be multiplied or divided by the same quantity, the products or quotients will be equal; and, lastly, if equal quantities be raised to the same power, or have the same root extracted out of each, the results will still be equal. From these considerations are derived the following rules, which apply alike to equations of all orders, and are alone sufficient for the resolution of simple equations. 63. Rule 1. Any quantity may be transposed from one side of an equation to the other, by changing its signs. Thus, if x — 3=5, Then x=5-{-3, Or a;=8. And if 3# — 10=2a: + 5, Then 3x — 2a:=5-f.l0, Or *= 15. Again, 'tfax^-b—cx — dx^-e. Then ax — cx -f- dx=e — b, Or (a — c-{-d)x=e — b. The reason of this rule is evident, for the transposing ot a quantity from one side of an equation to the other is nothing more than adding the same quantity to each side of the equation, if the sign of the quantity transpose! was — ; or subtracting it, if the sign was +. , From this rule we may infer, that if any quantity be found on each side of the equation with the same sign>1 may be left out of both. Also, that the signs of all t e terms of an equation may be changed into the contrary, without affecting the truth of the equation. AlgO, VX'Y'*' Thus, if a-\-x=.b-±a — c, Then x=b-\-c; And if a — x—b — d, Then x — a—d—b. 64. Rule 2. If the unknown quantity in an equation be multiplied by any quantity, that quantity may be taken away, by dividing all the other terms of the equation by it. If 3.r=24, Then If 24 Q ir~8‘ ALGEBRA. 4_q denoted by the index of the surd, and thus the unknown Algebra, quantity shall be freed from the surd expression. If / «-{-6=:10, Then, by transposition, y/x = lO — 6=4; And, squaring both sides, vA X V''a;=4 x 4, Or #=16. Also, if By trans. ax=b — c, b — c Then x= Then #=35. c + d, V a2-}-#2 — b—x, a/®2 -f- #2 = 6 -j- #, And, squaring, a2-f-#2= (7>-f-#)2; Hence «2= 62 2bx. And if Then a2x — b-x~x, a a a Here equal quantities are divided by the same quan¬ tity, and therefore the quotients are equal. 65. Rule 3. If any term of an equation be a fraction, its denominator may be taken away, by multiplying all the other terms of the equation by that denominator. jf 5- '> If-=6 a Then x—ab — ac-\-ad. T, b If a —c, x We have ax — b—cx. In these examples, equal quantities are multiplied by the same quantity, and therefore the products are equal. 66. The denominators may be taken away from several terms of an equation by one operation, if we multiply all the terms by any number which is a multiple of each of these denominators. Thus,if|+|+^=26; let all the terms be multiplied by 12, which is a multiple of 2, 3, and 4, and we have 12# 12# 12#_ ~~2~+ir+"4-- ; Or 6#4-4#-|-3#=312; Hence 13#= 312. TT * 11 . n X X X 7 Universally, if -r4--=« — e: a b e to take away the denominators a, b, c, let the whole equation be multiplied by a b c, their product, and we have bex — acx-\-abx—abc (d—e), Or {be — ac-\-ab) x=abc (d—e). From the last two rules it appears, that if all the terms of an equation be either multiplied or divided by the same quantity, that quantity may be left out of all the terms. If ax—ah — ac, Then x—b — c ; . , . # b e And if -=—4-—, a a ' a Then xzzb-\-c. f'h Rule 4. If the unknown quantity is found in any term which is a surd, let that surd be made to stand alone on one side of the equation, and the remaining terms °o the opposite side ; then involve each side to a power VOL II. (fix— Ifix—x?. 68. Rule 5. If the side of the equation which contains the unknown quantity be a perfect power, the equation may be reduced to another of a lower order, by extracting the root of that power out of each side of the equation. Thus, if #3=64a3, Then, by extracting the cube root, #=8a; And if (a-^xy—lfi — «2, Then a -f- #= Vlfi — a2. 69. The use of the preceding rules will be further illus¬ trated by the following examples : Ex. 1. Let 20 — 3# — 8=60 — 7#, By rule 1, 7# — 3#=60-J-8 — 20, Or 4#=48, Therefore, by rule 2, #=12. Ex. 2. T. e t ax — b ex -\-d, By rule 1, ax — cx—b-\-d, Or (a — c)#=&-f-v/#-j-;r> And by transposition, 8=4^#, And by division, 2=v^#, And again, by rule 4, 4=#. 2a2 Ex. 10. Let #+ Va2+x2 = ^ ; Then, by rule 3, # q2-|-#2-j-fl!2-|-#2=2a2, And by transposition, &c. #\/a2 + #2=«2— Therefore, by rule 4, a2#2 + #4=cs4 — 2a2#2+ #4, Whence 3a2#2=a4, cs And #2 = -g-, therefore, by rule 5, #= ^=> Ex. 11. Let 1—_a 1 +/l—#2 -#2 Then 1 — “y/l—#2=a + cs\/l And 1—a—aV 1—#2 + y//l—#2 =(l-{-a)V/l— 1 — a ALGEBRA. second power of that quantity, has been made to stand AL alone on one side of the equation, while the other con-v^ sisted only of known quantities ; but the same methods of reduction serve to bring equations of all degrees to a pro- per form for solution. Thus, if ~^~ ^ - = l—p—x^ —; by proper reduction, we have *3+/>#2+5'#=r, acubic equation, which may be resolved by rules to be afterwards explained. Sect. VII.—Of the Reduction of Equations in¬ volving MORE THAN ONE UNKNOWN QUANTITY. 70. Having shown in the last section in what manner an equation involving one unknown quantity may be re¬ solved, or at least fitted for a final solution, we are next to explain the methods by which two or more equations, in¬ volving as many unknown quantities, may at last be re¬ duced to one equation and one unknown quantity. As the unknown quantities may be combined together in very different ways, so as to constitute an equation, the methods most proper for their elimination must therefore be various. The three following, however, are of general application, and the last of them may be used with ad¬ vantage, not only when the unknown quantity to be eli¬ minated rises to the same power in all the equations, but also when the equations contain different powers of that quantity. 71. Method 1. Observe which of the unknown quanti¬ ties is the least involved, and let its value be found from each equation, by the rules of last section. Let the values thus found be put equal to each other, and hence new equations will arise, from which that quan¬ tity is wholly excluded. Let this operation be now re¬ peated with these equations, thus eliminating the unknown quantities one by one, till at last an equation be found which contains only one unknown quantity. Ex. Let it be required to determine # andy from these two equations. Whence 1 -j- a =V/1 —#2 ; And, taking the square of both sides, W——^ =1 — Therefore, by transposition, #2=1 — (1 -j- a)2—(1—a)2 _ (l+«)2 O—«)2> (l + a)2 That is, #2 = 4a (l + a)2 (l+«)2 Therefore x— 1 -j-G Ex. 12. Let a-j-#=V/,«2-|-#y,i2-}-#2, Then (a-{-#)2=a2-}-#V/62 + #2, rs. V/ 2# + 3y=23, 5#—2y=10. From the first equation, And From the second equation, And 2#=23—3y, 23—3y 5#= 10-{-27/, l°+> #_—5 . And we have That is,«2-f- 2a#4-#2=a24-#V/i2-f-#2> Therefore 2a# 4- #2 = #a/i2 4- #2, And dividing by #, 2a 4-# = v^fi2 4- ^ Again, taking the squares of both sides, 4a2 4.4a# 4-#2= 6s 4. #2, Whence 4a24-4a#=&2, 72 4y;2 And 4a#=&2—4a2 ; so that x——: . 4a In all these examples we have been able to determine the value of the unknown quantity by the rules already delivered, because in every case the first, or at most the Let these values of # be now put equal to each other, 104-2y_ 23—2y 5 ~ 2 ’ Or 204-4y=125—15y; Therefore 19y=95, And y=5: And since x— or #=--~j~ ^, from either of £ o these values we find #=4. 72. Method 2. Let the value of the unknown quantity which is to be eliminated be found from that equation wherein it is least involved. Let this value and its powers be substituted for that quantity, and its respec¬ tive powers in the other equations; and with the new equations thus arising, let the operation be repeate till there remain only one equation and one unknown quantity. Alg('a- A L G E Ex. Let the given equations, as in last method, be 2a?-(-3?/=: 23, 5x—2y=10. 23—3y From the first equation, x= —-— ; And hence x z= z=4, as before. Ex. 1. Given (H= 4 BRA. 443 The value of y being substituted in either of the values Algebra. of x, namely, 32 — ^, or 10+^, we find *=20. 57/ \nd this value of x being substituted in the second , r 23—3y ^ equation, we have 5 X —^ 2^=10, Or 115 — 15w — 4^=20; Therefore 95=1%, And 5=7/, 23-37/ 73. Method 3. Let the given equations be multiplied or divided by such numbers or quantities, whether known or unknown, that the term which involved the highest power of the unknown quantity may be the same in each equation. Then, by adding or subtracting the equations, as occa¬ sion may require, that term will vanish, and a new equa¬ tion emerge, wherein the number of dimensions of the un¬ known quantity in some cases, and in others the number of unknown quantities, will be diminished ; and by a re¬ petition of the same or similar operations, a final equa¬ tion may be at last obtained, involving only one unknown quantity. Ex. Let the same example be taken, as in the illustra¬ tion of the former methods, namely, 2x -f- 3y=23, 5x—2//= 10 ; and from these equations we are to determine x and 7/. To eliminate x, let the first equation be multiplied by 5, and the second by 2; thus we have 10* + 15y= 115, 10*— 4-t/= 20. Here the term involving * is the same in both equations; and it is obvious, that by subtracting the one from the other, the resulting equation will contain only y, and known numbers; for by such subtraction we find 19y=95, and therefore y=5. Having got the value of 7/, it is easy to see how * may be found, from either of the given equations ; but it may also be found in the same manner as we found y. For let the first of the given equations be multiplied by 2, and the second by 3, and we have 4*-j-6y=46, 15*—6y=30. By adding these equations, we find 19*=76, and |/=4. 74. The following examples will serve further to illus¬ trate these different methods of eliminating the unknown quantities from equations. .By Method 2. Having found from the first equation *=32 —Si, let this value of * be substituted in the second, and I(32-|)-|=2, °r Hence 198= 1 \y and y= 18. The value of y being now substituted in either of the given equations, we thence find *=20, as before. By Method 3. The denominators of the two given equations being taken away by rule 3 of last section, we have 3*+ 2y=96, 9*—5y=90. From three times the first of these, or 9*-j-6y = 288, let the second be subtracted, there remains 1 \y= 198 and y= 18. The value of y being now substituted in either of the equations 3*+% = 96, 9*—5y = 90, we readily find * = 20. 75. Having shown in what way the different methods of eliminating the unknown quantities may be applied, we shall, in the remaining examples of this section, chiefly make use of the last method, because it is the most easy and expeditious in practice. £?*. 2. Given { 1-12 = 1+8, 2 x+y - 2y—x •27. 5 1 3 4 It is required to determine * and y. From the 1st equation, 4*—96=2y-f-64; From the 2d, 12*-J- \2y-\-20x—480=30y—15*+ 1620* These equations, when abridged, become 4* — 2_y=160, 47*—18?/=2100. To eliminate y; from this last equation let 9 times the one preceding it be subtracted. Thus we find 11*=660, and *=60 ; And because 2y=Tx—160=80, Therefore ?/=40. required * and y. Ext 3. Given to determine * and y. 2y By Method 1. From the first equation, *=32 — And from the second, *=10+^; y Therefore 10+^(-=32 — y o Or 90 + 5y = 288 — 6y ; Hence lly=198 and ^=18. To eliminate y, let the first equation be multiplied by f, and the second by b, and we have afx + bfy=cf’ bdx-\-bfy=by. Taking now the difference between these equations, afx — bdx=cf— bg, Or (of— bd)x=cf— bg, cf—bg And therefore x= ^ In the same manner may 3/ be determined, by multiply- 444 ALGEBRA. Algebra, ing the first of the given equations by d, and the second ' by a ; for we find adx -f- bdy—cd, adx-\-afy—ag. And taking the difference as before, we get bdy — afy—cd—ag, » , , cd—ag And therefore V-ti > ^ bd — aj This last example may be considered as a general solu¬ tion of the following problem. Two equations expressing the relation between the first powers of two unknown quantities being given, to determine those quantities; for whatever be the number of terms in each equation, it will readily appear, as in example 2, that by proper reduction they may be brought to the same form as those given in the third example. 76. Let us next consider such equations as involve three unknown quantities. (x+y+z =29 J *-j-% + 3^=62 . y z (2 + 3 + 4 We shall in this example proceed by the first method for eliminating the unknown quantities. From the first equation, x=29—y — z, From the second, x—Q2 — 2y — 82, 2?/ z From the third, x=20 ^ -. Let these values of x be put equal to each other ; thus we get the two following equations : 29 —y — z—62 — 2y — 3z, .?/-z=20—3— Tdx. 4. Given :29) :62 f l0) to find x, y, and z. 29- Again, from these equations, by transposition, &c. 3/= 33—2z, 3z Therefore And 33 — 2z—21 ■ 3z ' 2 ' And hence, by reduction, 2=12 Whence also, 3/=33 — 22=9, £=29—y — 2=8. Ex. 5. Given < x V z 2 + 3 + 4-62 ^-I-'-7 4--^=47 [> to find x, y, and 2. 3 4*5 X.L.y A.Z-^ 4 + 5 + 6-38 Next, to eliminate y, let the first of these equations be a multiplied by 3, and the second by 5; hence, ^ 60£+153/= 2340, 50£-(-15y=2100. Subtracting now the latter equation from the former, 10£=240 and £=24, ™ , 420—10£ Therefore yz=. 3 =60, Here the given equations, when cleared from fractions, become 12£-}- 83/-f- 62=1488, 20£+ 15?/-f-122=2820, 30£ -{- 243/ -f- 202=4560. To eliminate 2 by the third method, let the first equa¬ tion be multiplied by 10, the second by 5, and the third by 3, the results will be these: 120£ + 803/ + 602=14880, 100£ + 75y + 602= 14100, 90£ + 723/ + 602= 13680. Let the second equation be now subtracted from the first, and the third from the second, and we have . 20£ + 53/=780, 10£-|-3y=420. And 1448—12£ — 8?/ ?= 3 = 120. b 77. From the preceding examples, it is manifest in what manner any number of unknown quantities may be determined by an equal number of equations, which con¬ tain only the first power of those quantities, in the nume¬ rators of the terms. Such are the following: ax + % + cz—n, dx+cy+fzz=p, gx + hy + kz=q ; where a, b, c, &c. represent known, and £, y, z, unknown quantities; and in every case the unknown quantities may be directly found, for they will be always expressed by whole numbers or rational fractions, provided that the known quantities, a, b, c, &c. are also rational. 78. We shall now add a few examples, in which the equations that result from the elimination of an unknown quantity rise to some of the higher degrees; and there¬ fore their final solution must be referred to the sections which treat of those degrees. Ex. 6. Let£ — y=2, and xy + 5x — 63/=120; it is re¬ quired to eliminate x. From the first equation x = y-\-2; which value being substituted in the other equation according to the second general method (sect. 72) it becomes . (y+2)y+5(y+2) — 6y =120’ that is, y2-[-2y + 5 y-\-10 — 63/ = 120; therefore the equation required is y2-\-y=110. Ex. 7. There is given £ -J- 3/ = and aPifrzb, to eliminate x. From the first equation x=a — y, and —y)2, And from the second £2=5 — y2 ; Therefore (a — y)2—b — y2; That is, a2 — 2ay ■\-y2—b — y2. Hence 2y2 — 2ay — b — a2; an equation involving only y. Ex. 8. Given ^ From the first equation y = And from the second y = d — bx ax -{-c7 k — gx Therefore d — bx fx + h ' k — gx Ex. 9. Given _ t?) ax c fx -{- h 7 an equation in which the unknown quantity y is not found. to elimi¬ nate y. As the co-efficient of y2 is unity in both equations, if their difference be taken, the highest power of y will va¬ nish ; but to give a general solution, let the terms of the equations be all brought to one side and made equal to 0, thus, y2 — (3£ — d) y — = 0, y2 — by + 2ax — 4£2-j-^2=0* ALGEBRA. and in the second, 1 = D, —6 = E, 2ax — 4;c2 + 62 sF; and the two become A?f E/y + C=0, D^+Ey+F=0. To eliminate y2, let the first equation be multiplied by D, and the second by A ; then ADy2 + BDy+CD=0, ADy2 + AEy + AF=: 0. Therefore, taking the difference of these equations, (BD —AE)y + CD —AF=0, t J AF —CD And y = BD-AE- Again, to find another value of y, multiply the first equation by F, and the second by C ; then AFy2 + BFy + CF=0, CDy2 + CEy+CF=0. Therefore, subtracting as before, (AF—CD)y2 + (BF—CE)y= 0, And dividing by y, (AF — CD)y + BF — CE = 0. CE —BF Therefore y= • Let this value of y be put equal to the former, then AF —CD_ CE —BF BD —AE~AF —CD 5 And therefore (AF — CD)2=(BD— AE) (CE — BF). Now, as y does not enter this equation, if we restore the values of A, B, C, &c. we have the following equa¬ tion, which involves only x and known quantities. (i2 + 2(mi — S#2)2 = [a + 6 — [foe2 — (a — 3*) (2ax—4^+^)]. This equation, when properly reduced, will be of the fourth order, and therefore its final resolu¬ tion belongs not to this place. Sect. VIII.—Questions producing Simple Equations. 79. When a problem is proposed to be resolved by the algebraic method of analysis, its true meaning ought in the first place to be perfectly understood, so that, if ne¬ cessary, it may be freed from all superfluous and ambi¬ guous expressions, and its conditions exhibited in the clearest point of view possible. The several quantities concerned in the problem are next to be denoted by pro¬ per symbols, and their relation to one another expressed agreeably to the algebraic notation. Thus we shall ob¬ tain a series of equations, which, if the question be pro¬ perly limited, will enable us to determine all the unknown quantities required by the rules already delivered in the two preceding sections. 80. In reducing the conditions of a problem to equa¬ tions, the following rule will be of service. Suppose that I the quantities to be determined are actually found, and then consider by what operations the truth of the solution may be verified; then let the same operations be per- tonned upon the quantities, whether known or unknown, and thus all the conditions of the problem will be reduced to a series of equations, such as is required. For example, suppose that it is required to find two numbers, such, that t loir sum is 20, and the quotient arising from the division o their difference by the lesser 3; then if we denote the greater of the two numbers by x, and the lesser by y, and proceed as if to prove the truth of the solution, we shall lave a;-f y for the sum of the numbers, and a: — yfor icir difference. Now, as the former must be equal to 20, j*.n "j,6 latter divided by y equal to 3, the first condi- ■on of the problem will be expressed by this equation, In the first equation put 1 = A, — (3# — a) = B, —x2 x + i/=z20, and the second by and from these, the values of x and y may easily be found. 81. When the conditions of a problem have been ex¬ pressed by equations, or translated from the common language into that of algebra, we must consider whether the problem be properly limited; for in some cases the conditions may be such as to admit of innumerable solu¬ tions, and in others they may involve an absurdity, and thus render the problem altogether impossible. Now, by considering the examples of last section, it will appear, that to determine any number of unknown quantities, there must be given as many equations as there are unknown quantities. Thfese, however, must be such as cannot be derived from each other, and they must not in¬ volve any contradiction ; for in the one case the problem would admit of an unlimited number of answers, and in the other case it would be impossible. For example, if it were required to determine x and y from these two equa¬ tions, 2x — 3y — 13, 4or—6y=26; as the latter equation is a consequence of the former (for each term of the one is the half of the corresponding term of the other), it is evident, that innumerable values of x and y might be found to satisfy both equations. Again, if x and y were to be determined from these equations, « + 2y—8, 3a: + 6yr=26, it is easy to see that it is impossible to find such values of x and y as will satisfy both ; for, from the first, we find 3#= 24 — 6y ; and from the second, 3a: rr 26 — 6y ; and therefore 24—6y = 2G—6y, or 24 = 26, which is absurd; and so also must have been the conditions from which this conclusion is drawn. 82. But there is yet another case in which a problem may be impossible; and that is, when there are more equations than unknown quantities; for it appears, that in this case, by the rules of last section, we would at last find two equations, each involving the same unknown quantity. Now, unless these happened to agree, the pro¬ blem would admit of no solution. On the whole there¬ fore it appears, that a problem is limited when the con¬ ditions furnish just as many independent equations as there are known quantities to be determined: if there be fewer, the problem is indeterminate; but if there be more, the problem in general admits of no solution what¬ ever. 83. In expressing the conditions of a problem by equa¬ tions, it will sometimes be convenient to introduce as few symbols of unknown quantities as possible. Therefore, if two quantities be sought and their sum be given, suppose it = s ; then if the one quantity be represented by x, the other may be denoted by s — x. If, again, their difference be given = d, the quantities may be denoted by x, and d-\-x,ov by x, and # — d. If their product be given = p, the quantities are x, and ^; and so on. 84. We shall now apply the preceding observations to some examples, which are so chosen as to admit of being resolved by simple equations. Ex. 1.

Thus it appears, that the number sought is 24, which upon trial will be found to answer the conditions of the question. Ex. 2. A post is ^ of its length in the mud, ^ in the water, and 10 feet above the water; what is its whole length ? Let its length be x feet, then the part in the mud is f, and that in the water |; therefore, from the nature of 4 o the question, i+ii+lO From this equation we find 7#-f 120:= 12#, and #=24. Ex. 3. Two travellers set out at the same time from London and York, the distance between which places is 150 miles ; the one goes 8 miles a day, and the other 7: in what time will they meet ? Suppose that they meet after # days. _ Then the one traveller has gone 8# miles, and the other 7# miles ; now the sum of the distances they travel is, by the question, equal to the distance from London to York. Therefore 8# + 7#= 150, That is, 15#= 150, and #=10 days. Ex. 4. A labourer engaged to serve for 40 days, upon these conditions; that for every day he worked he was to receive 20d., but for every day he played or was absent, he was to forfeit 8d.: now at the end of the time he had to receive L.l. 11s. 8d. It is required to find how many days he worked, and how many days he was idle. Let # be the number of days he worked ; Then will 40—# be the number of days he was idle, Also 20 x #=20#= the sum he earned in pence, And 8 x (40 — #)=320 — 8#= the sum he forfeited. Now the difference of these two was L.L 11s. 8d. or 380d.; Therefore 20# — (320 — 8#)=380; That is, 28#= 700. Hence #=25= the number of days he worked, And 40 — #=15= the number of days he was idle. Ex. 5. A market-woman bought a certain number of eggs at 2 a penny, and as many at 3 a penny, and sold them all out again at 5 for 2d.; but, instead of getting her own money for them, as she expected, she lost 4d.: what number of eggs did she buy ? Let # be the number of eggs of each sort; Then will ^ be the price of the first sort, 4W X And - = the price of the second sort. Now, the whole number being 2#, we have 5 : 2# :: 2 : -^- = price of both sorts at 5 for 2d.; X X ^x Therefore „ +w 4, by the question. Hence 15# 10# — 24#= 120, And #= 120, the number of each sort. Ex. 6. A bill of L.120 was paid in guineas andmoidores: the number of pieces of both sorts used was 100; how many were there of each ? Let the number of guineas be #; Then the number of moidores will be 100 — #; Also the value of the guineas, reckoned in shillings, will be 21#, and that of the moidores 27(100—#)=2700—27#; Therefore, by the question, 21# +2700—27#=2400. Hence 6#=300, and #=50 ; So that the number of pieces of each sort was 50. Ex. 7. A footman agreed to serve his master for L.8 h .fc a year and livery, but was turned away at the end of 7O ^ months, and received only L.2. 13s. 4d. and his livery; what was its value ? Suppose # the value of the livery, in pence. Then his wages for a year were to be #+1920 pence. But for 7 months he received # + 640 pence. Now he was paid in proportion to the time he served* Therefore 12 : 7 :: #+1920 : # + 640. And, taking the product of the extremes and means, 12#+ 7680=7#+ 13440. Hence 5#=5760d. and #=1152d.=L.4. 16s. Ex. 8. A person at play lost % of his money, and then won 3s.; after which he lost ^ of what he then had, and then won 2s.; lastly, he lost } of what he then had; and, this done, found he had only 12s. left: what had he at first? Suppose he began to play with # shillings. x x 3# He lost £ of his money, or -, and had left#—. tt „ I,,, 3# 0 3#+12 He won 3s. and had then —+ 3=—^—.

He lost j- of or — —, and had left ■* .CO 2#+16 2#+16 12#+ 96 4 28"“ “ 28 * And because he had now 12s. left, we have this equation, 1&+96 28 ~ ' Hence 12#=240, and #=20. Ex. 9. Two tradesmen, A and B, are employed upon a piece of work; A can perform it alone in 15 hours, and B in 10 hours : in what time will they do it when work¬ ing together? Suppose that they can do it in # hours, and let the whole work be denoted by 1. Then 15 : # :: 1 : ^ = the part of the work done by A. 15 And 10 : # :; 1 : the part done by B. Now, by the question, they are to perform the whole work between them; Therefore ^+^=1. Hence 25#= 150, and #=6 hours. Ex. 10. The sum of any two quantities being given = s, and their difference=c?, it is required to find each of the quantities. Let # denote the greater of the two quantities, and y the lesser. Then # + ■?/=$, and # — y—d. Taking the sum of the equations, we get 2#=s+“> And, subtracting the second from the first, 2y=s Therefore #=^-i-^, and y = ~ ■ . ALGEBRA. .i,, a. Ex. 11. A gentleman distributing money among some JrWpoor people, found he wanted 10s. to be able to give each 5S>; therefore he gave only 4s. to each, and had 5s. left. Required the number of shillings and poor people. Let the number of shillings be x, and that of the poor people y; then, from the nature of the question, we have these two equations, by—x-^-\0 \y—x — 5. From the first equation, x—by — 10, And from the second, x=fy-\-5-. Therefore 5?/ — 10=4;/-f-5 ; Hence y=:15, and x~ty + 5=:65. Ex. 12. A farmer kept a servant for every 40 acres of ground he rented, and on taking a lease of 104 more acres, he engaged 5 additional servants, after which he had a servant for every 36 acres. Required the number of servants and acres. 447 sum, difference, product, and quotient, shall be all equal Algebra, to each other. In this question there are four quantities to be deter¬ mined ; but instead of introducing several letters, having put x to denote the first of them, we may find an expres¬ sion for each of the remaining ones, as follows : Because a?-|-2=second quantity —2, Therefore a;-j-4z= the second quantity; And because #4-2= third x 2, cc | 2 Therefore—g— = the third quantity. And in like manner 2 (#4-2) = the fourth quantity. Now, by the question, the sum of all the four = 90; Therefore #4-#-j-44- —4-2(#4-2)=90. Hence 9#=162, and #=18 ; Therefore the numbers required are 18, 22, 10, and 40. Suppose that he had at first # servants, and y acres. From the first condition of the question, x-~-. And from the second, #4-5= By comparing the values of #, as found from these equations, we have y+I04j _ r,_iL 36 40* Hence 40y4-4160 — 7200=36?/, so that 4?/=3040; Therefore y = 760, and # = 19. Ex. 13. Two persons, A and B, were talking of their ages; says A to B, seven years ago I was just three times as old as you were then, and seven years hence I shall be just twice as old as you will be. What is their present ages? Let the ages of A and B be # and y respectively. Their ages seven years ago were # — 7 and y — 7, and seven years hence they will be #4-7 and 3/4-7. Therefore by the question *—7=3(3/—7) and x+ri=2(y + 7). From the first equation, #=83/—14, And from the second, #=23/4.7; Therefore Sy—14=23/4-7 ; hence 3/=21. And because x=2y-\-7, therefore #=49. Ex. 14. A hare is 50 leaps before a greyhound, and takes 4 leaps to the greyhound’s 3, but 2 of the grey¬ hound’s leaps are as much as 3 of the hare’s. How many leaps must the greyhound take to catch the hare ? In this example there is only one quantity required, it will, however, be convenient to make use of two letters ; therefore let # denote the number of leaps of the grey¬ hound, and y those of the hare ; then, by considering the proportion between the number of leaps each takes in the same time, we have 3 : 4:: #: 3/, hence 3y=ix. Again, by considering the proportion between the number 0 ^aPs each must take to run the same distance, we find *: SO-j-y;: 2:3, hence 100 4.23/=3#. from the first equation we find 63/= 8#, And from the second 63/= 9#—300. Hence 9#—300=8#, and #=300. if ^ divide the number 90 into 4 such parts, that th 16i •iSt \nc.reased by 2, the second diminished by 2, e t m'd multiplied by 2, and the fourth divided by 2, the Ex. 16. A and B together can perform a piece of work in 12 hours, A and C in 20, and B and C in 15 hours; in what time will each be able to perform it when working separately ? That we may have a general solution, let us suppose A and B can perform the work in a hours, A and C in i hours, and B and C in c hours. Let #, 3/, and z, denote the times in which A, B, and C, could perform it respec¬ tively, if each wrought alone; and let the whole work be represented by 1.

We are next to explain the resolution of equations of the second degree, or quadratic equations. These in¬ volve the second power of the unknown quantity, and may be divided into two kinds, pure and adjected. I. Pure quadratic equations are such as after proper reduction have the square of the unknown quantity in one term, while the remaining terms contain only known quantities. Thus, x1 2 3=64, and aa?-\-bz=zc, are examples of pure quadratics. II. Adjected quadratic equations contain the square of the unknown quantity in one term, and its first or simple power in another ; the remaining terms consisting entire¬ ly of known quantities. Such are the following, + =28, 2^=33 — bx, ax^-jbx — c-=.d. The manner of resolving a pure quadratic equation is sufficiently evident. If the unknown quantity be made to stand alone on one side, with unity as a co-efficient, while the other side consists entirely of known quantities, and the square root of each side be taken, we immediately ob¬ tain the value of the simple power of the unknown quan¬ tity as directed by rule 5th of sect. VI. 86. In extracting the square root of any quantity, it is necessary to observe, that the sign of the root may be either q- or —. This is an evident consequence of the rule for the signs in multiplication; for since by that rule any quantity, whether positive or negative, if multiplied by itself, will produce a positive quantity, and therefore the square of -\-a, as well as that of — a, is + a2; so, on the contrary, the square root of -f- a2 is to be considered either as -f- « or as — a, and may accordingly be express¬ ed thus, z±za. 87. Having remarked that the square of any quantity, whatever be its sign, is always positive, it evidently fol¬ lows that no real quantity whatever, when multiplied by itself, can produce a negative quantity; therefore, if the square root of a negative quantity be required, no such root can be assigned. Hence it also follows, that if a pro¬ blem requires for its solution the extraction of the square root of a negative quantity, some contradiction must ne¬ cessarily be involved, either in the condition of the pro¬ blem, or in the process of reasoning by which that solu¬ tion has been obtained. 88. When an adfected quadratic equation is to be re¬ solved, it may always, by proper reduction, be brought to one or other of the three following forms : 1. x^ Jpx—q. 2. x?—px—q. 3. x?—px— —q. But as the manner of resolving each of the three forms is the very same, it Mull be sufficient if we consider any one of them. Resuming therefore the first equation, or x? Jpx—q, let us compare the side of it Mffiich involves the unknown quantity x with the square of a binomial #-{-«; that is, let us compare with a^-J-Sa^+a^^-j-a)2, and P it will presently appear, that if we suppose jp= 2a, or^=«, A the quantities x?-\-px and a^-l-2aa; will be equal; and as A j,r a^-|-2aa? is rendered a complete square, by adding to ita2,^ so also may x?-\-px be completed into a square by add¬ ing to it which is equal to a2; therefore, let^- be added to both sides of the equation x?-\-px=. q, and we have 4=4+^ °r (*+f)2=4+^‘ and, extracting the square root of each side, a: -p 2 =*= hence *= —f — d4 +?• 89. From these observations we derive the following general rules for resolving adfective quadratic equations. 1. Bring all the terms involving the unknown quantity to one side, and the known quantities to the other side, and so that the term involving the square of the unknown quantity may be positive. 2. If the square of the unknown quantity be multiplied by a co-efficient, let the other terms be divided by it, so that the co-efficient of the square of the unknown quantity may be 1. 3. Add to both sides the square of half the co-efficient of the unknown quantity itself, and the side of the equa¬ tion involving the unknown quantity will now be a com¬ plete square. 4. Extract the square root of both sides of the equa¬ tion, by which it becomes simple with respect to the un¬ known quantity; and by transposition, that quantity may be made to stand alone on one side of the equation, while the other side consists of known quantities; and therefore the equation is resolved. Note. The square root of the first side of the equation is always equal to the sum or difference of the unknown quantity, and half the co-efficient of the second term. If,the sign of that term be -f-, it is equal to the sum, but if it be —, then it is equal to the difference. Ex. 1. Given a?22a:=35, to determine x. Here the co-efficient of the second term is 2; therefore, adding the square of its half to each side, we have z2 + 2a:+1 = 35 +1=36, _ And, extracting the square root, # +1= V"36= 6. Hence x — 6— 1, that is a: = + 5, or a: —7, and either of these numbers will be found to satisfy the equation, for 5 x^+2 X^ = 35, also — 7 X ' + 2 x —7=35. x2 Ex. 2. Given — 6 12=a:, to find x. This equation, when reduced, becomes x? — 6a:=72, And, by completing the square, x? — 6a: + 9=72-j-9=81. Hence, by extracting the square root, x — 3= 9, and x = z±z 9 + 3 ; Therefore a: = + 12, or a: = — 6; and upon trial we find that each of these values satisfies the original equa¬ tion, for 12x 12 12 = 12, also ~6 * ZlQ —12 = —-ffi Ex. 3. Given a^+28=lla:, to find x, Then a?—lla:= — 28. 121 _121 And, by completing the square, x? — lla:+-+p-— ^ algebra. ^Alhri^ Therefore, by extracting the root, x — i-- Hence x—- 11 =-; that is, x— + 7, or x= + 4. In the first two examples, we found one positive value for x in each, and also one negative value; but in this example both the values of x are positive, and, upon trial, each of them is found to satisfy the equation; for 7X7 + 28=11X7, also 4X4 + 28=11X4. 90. As at first sight it appears remarkable, that in every quadratic equation the unknown quantity admits always of two distinct values or roots, it will be proper to consider a little further the circumstances upon which this peculiarity depends. This is the more necessary, as the property of the unknown quantity admitting of seve¬ ral values is not peculiar to quadratics, but takes place also in equations of the higher degrees, where the cause of the ambiguity requires an explanation somewhat dif¬ ferent from that which we have already given in the pre¬ sent case. 91. Let us again consider the equation ^+2^=35, which forms the first of the three preceding examples. By bringing all the terms to one side, the same equation may be also expressed thus, x2-\-2x — 35=0 ; so that we shall have determined x, when we have found such a number as, when substituted for it in the quantity ar!+2,z —35, will render the result equal to 0. But ^+2* —35 is the product of these two factors a: — 5 and *+7, as may be proved by actual multiplication; therefore, to find x, we have (x — 5) (+ + 7)=0; and as a product can only become =0 when one of its fac¬ tors is reduced to 0, it follows that either of the two factors a: ■— 5 and a;+7 maybe assumed =0. If a;—5=0, then a=5; but if a? + 7=0, then x= — 7; so that the two values of x, or two roots of the equation ar2 + 2a=:35, are +5 and — 7, as we have already found in a different manner. 92. What has been shown in a particular case is true of any quadratic equation whatever; that is, if a?+j»a:=^, or, by bringing all the terms to one side, a^+joar — g=0, it is always possible to find two factors x — a, and x-i-b, such, that a?+px+q=(x — a) (x + b), w icre a and b are known quantities, which depend only upon p and q, the given numbers in the equation; and since that to have (a; — a) (a; + 6)=0, we may either as¬ sume a— «=0 or a; + 6=0, it evidently follows that the conditions of the equation x?+px — o=0, or a?+»a?=7, are alike satisfied by taking x— +a or a?= —b. From these considerations it follows, that x can have only two values in a quadratic equation ; for if it could be supposed to have three or more values, then it would De Posslble to resolve x?+px—q into as many factors, j—c, x—d, &c.; but the product of more than two fac- ors must necessarily contain the third or higher powers o x, and as a2 -j- px — q contains no higher power place ^ ^ Secon^’ therefore no such resolution can take 93. Since it appears thata2+joa — q maybe consider- , as the product of the two factors x — a and a+ 6, c us examine the nature of these factors. Accordingly, akmg then- product, we find it x? + (b — a)x — ab; and thafA 18 (luantlty must be equal to tf+px — q, it follows a—p and ab—q, or, changing the signs of the equations a — b_~p and —g-, we derive the fol- Algebra, lowing proposition relating to the roots of any quadratic equation. The sum of the roots of any quadratic equa¬ tion a2is equal to —p, that is, to the co-efficient of the second term, having its sign changed; and their product is equal to —q, or to the latter side of the equa¬ tion, having its sign also changed. n This proposition enables us to resolve several import¬ ant questions concerning the roots of a quadratic equa¬ tion, without actually resolving that equation. Thus we learn from it, that if q, the term w-hich does not involve the unknown quantity (called sometimes the absolute number), .be positive, the equation has one of its roots positive and the other negative ; but if that term be ne¬ gative, the roots are either both positive or both negative. It also follows, that in the former case the root which is denoted by the least number will have the same sign with the second term; and in the latter case, the common sign of the roots will be the contrary to that of the second term. 94. From this property of the roots we may also derive a general solution to any quadratic equation x?-\-px=q ; for we have only to determine two quantities whose sum is ~~p and product —q, and these shall be the two values of x, or the two roots of the equation. Without considering the signs of the roots, let us call them v and z; then v-\-z=—p, and vz——q. From the square of each side of the first equation let four times the second be subtracted, and we have v*— %vz + z2=/>2-f-4<7, or (v — z'fzz.j? + 4// therefore, v — z= =±= Vpr + 4y. From this equation, and from the equation v-\-z——p, we readily obtain r=——~ ^ Jhiff —-y3=pVy+4^ 2 ; that is, if v— —TH^Fj+Ty then z= -grW,++ and if *==£=^±1?, then z-. —y?+'V/j»2 + 4§’ - - enns of both equations, a — b-—p, — ab-~_ .~t~ ^7 2 2 which agrees with the conclusion we have already found (sect. 89). 95. It appears, from what has been already shown, that the roots of a quadratic equation xt+px—q always involve the quantity Vy>2+42+4§' must be a positive quantity; for if it were nega¬ tive, as the square root of such a quantity could not be found, the value of x could not possibly be obtained. If, for example, the value of x were required from this equation, a^+13=4a;, or a?2 — 4a? = — 13, we should find x = 2 z±=. V — 9; and as this expression for the roots requires us to extract the square root of — 9, the equation from which it is derived must necessarily have involved some contradiction. It is not difficult to see wherein the absurdity consists; for since in this case P = — 4, and q = — 13, the roots of the equation ought to be both positive (sect. 93), and such that 3 L 450 ALGEBRA. Algebra, their sum = 4, while their product = 13 (sect. 93), which is impossible. 96. Although imaginary quantities serve no other pur¬ pose in the resolution of quadratic equations than to show that a particular problem cannot be resolved, by reason of some want of consistency in its data, yet they are not upon that account to be rejected. By intro¬ ducing them into mathematical investigations, many cu¬ rious theories may be explained, and problems resolved, in a more concise way than can be done without the use of such quantities. This is particularly the case in the higher parts of the mathematics. The method which has been applied to the ‘resolution of quadratic equations properly so called, namely, such as are of this form, v?-\-px — q, will also apply to all equations of this form, oi?n-\-pxn — q, where the unknown quantity x is found only in two terms, and such that its exponent in the one term is double that in the other; for let us assume xn = y, then x2" = y2, and therefore the equation 3t?n -irpxn — q becomes f^-py-q, a quadratic equation, from which x may be found, and thence x, by considering that x — Wy. 97. Although every quadratic equation admits of two roots, yet it will frequently happen that only one of them can be of use, the other being excluded by the conditions of the question. This will often be the case with respect to the negative root; as, for example, when the unknown quantity denotes a number of men, a number of days, &c. And hence, in reckoning the cases of quadratic equations, it is common to neglect this one, a? -\-pxz=. q, where the roots are both negative; for an equation of this form can only be derived from a question which has some fault in its enunciation, and which, by a proper change in its form, will produce another equation having both its roots positive. 98. The remainder of this section shall be employed in solving some questions which produce quadratic equa¬ tions. Ex. 1. It is required to divide the number 10 into two such parts that the sum of their squares may be 58. Let x be the one number ; Then, since their sum is 10, we have 10 — x for the other; And by the question (10 — x)2z=58 ; That is, ic2-)-100 — 20x-^-xPzz58, Or 2x2—20x = 58— 100= — 42; Hence 10a; = —21. And completing the square, x2— 10a;-f 25=25 — 21 = 4 ; Hence, by extracting the root, x — 5==±=V/4=rt:2 And a;=5r±z2, . That is, .r=7,ora;=3. If we take the greatest value of x, viz. 7, the other number 10—x will be 3 ; and if we take the least value of xt viz. 3, then the other number is 7. Thus it appears, that the greatest value of the one number corresponds to the least of the other; and indeed this must necessarily be the case, seeing that both are alike concerned in the question. Hence, upon the whole, the only numbers that will answer the conditions of the question are 7 and 3. Ex. 2, What two numbers are those whose product is 28; and such, that twice the greater, together with thrice the lesser, is equal to 26 ? Let a;be the greatest and y the least number; then, from Alg the nature of the question, we have these two equations, xy—28, 2a; + 3?/=26. 28 From the first equation we have y=. —, 26 — 2a; And from the second y~ 5 • 26— 2x 28 ' x Hence o u And, reducing, 26.r — 2^=84, Or 2a^ — 26x= 84, Hence a? — 13*= — 42. And comp, the sq. ot?— 13*-j-JA£ = — 42=£. Hence,by extracting the root,*—J|-==±:V^=d=l, Therefore *=1T—2 » That is, *=7, or*=6. 28 And since y~ —> we have ?/=4, or y—^j- Thus we have obtained two sets of numbers, which ful¬ fil the conditions required, viz. x=7, y=4 : Or *=6, y=-y\ And besides these, there can be no other numbers. Ex. 3. A company dining together at an inn, find their bill amount to 175 shillings ; two of them were not allow¬ ed to pay, and the rest found that their shares amounted to 10 shillings a man more than it they had all paid. How many were in company ? Suppose their number to be *.

And, because L.54= 1080 shillings, we have by the question 1900 (a: — 15) (ifri + 2) =1080 ; X Which, by proper reduction, becomes a;2-f-45 #=9000; And, completing the square, a^-f45 xq __ = —_—.

If x — 3, then the other number is 2, and if a: = 2, the other number is 3; so that 2 and 3 are the numbers re¬ quired. In general, if it be required to find two numbers which are exactly alike concerned in a question that produces a quadratic equation, they will be the roots of that equa¬ tion.

X.—Of Equations in general. Ex. 6. What number is that which, when divided by the product of its two digits, the quotient is 3 ; and if 18 be added to it, the digits are inverted ? Let x and y denote the digits ; then the number itself will be expressed bylO:r-f-y> and that number in which the digits are inverted, by y-\-x. Thus the conditions of the problem will be expressed by these two equations, = 3, 10 x+y+18 = 10 y + x. xy From the first equation we have ?/=-^—j-, And from the second, y—x-\-2 ; Therefore x-\-2—~p And Sx2 -f. 5x—2= 10a:.

If a=4, the other number is -L^= 25, and if a: = 25, then the other number is 4; so that, in either case, the two numbers which answer the conditions of the question are 4 and 25. Ex. 8. It is required to find two numbers, of which the product shall be 6, and the sum of their cubes 35. 99. Before we proceed to the resolution of cubic and the higher orders of equations, it will be proper to ex¬ plain some general properties which belong to equations of every degree, and also certain operations which must frequently be performed upon equations before they be fitted for a final solution. In treating of equations in general, we shall suppose all the terms brought to one side, and put equal to 0; so that an equation of the fourth degree will stand thus: xi-\-px3+qx^-{-rx+s=0, where x denotes an unknown quantity, and p, q, r, s, known quantities, either positive or negative. Here the co-efficient of the highest power of x is unity, but had it been any other quantity, that quantity might have been taken away, and the equation reduced to the above form, by rules already explained (Sect. VI). The terms being thus arranged, if such a quantity be found as, when substituted for x, will render both sides = 0, and therefore satisfy the equation, that quantity, whether it be positive or negative, or even imaginary, is to be considered as a root of the equation. But we have seen that every quadratic equation has always two roots, real or imaginary; we may therefore suppose that a simi¬ lar diversity will take place in all equations of a higher degree; and this supposition appears to be well founded, by the following proposition, which is of great importance in the theory of equations. If a root of any equation, as o^-\-pxs-\-qx-\-r—Q, be re¬ presented by a, the first side of that equation is divisible by x—a; '*■ For since x^Jrp3^J^qociJ[-rx-\‘S'=zO, And also a4 -f-pa3 -f- qa2 -|- -f- s= 0 ; Therefore, by subtraction, a:4—a4 -f-pC#3—a3) + q(x?—a2) -f r(x—a)=0. But any quantity of this form xf1—an.y where n denotes a whole positive number, is equal to (x—a)(a:n-1 + ax*-2 + aV*-3 +... + an~2x+a”-1), as may be proved by multiplication; therefore, putting a:=:4, 3, and 2 successively, we have ie4—a*—(x—a)(xP a?x 4- a3), x3—a3=(x—a)(a^-j-a;K+a2)> a?—a2= (x—a)(x 4- a), x —a =(x—a) ; and by substitution, and collecting into one term the co¬ efficients of the like powers of x, the equation becomes 452 ALGEBRA. Algebra, (a;—a) [a^-f (a -\-p) (“2 -\-pa + y) a; -f a3 + pa2 + ^ + —0; so that, putting/? —a -f-p, tf—cP+pa + q, P—cP + pcP -\-qa-\-r, we have xv -\-px? 4* qx1 -\-rx-\- s^z(x—o)(r3+//a2 + c/x + r'). Hence, if the proposed equation x^+potP + qxP-^rrx-^-s be divided by x—a, the quotient will be x?-\-p'oc2q'x-\-r, an integer quantity; and since the same mode of reason¬ ing will apply to any equation whatever, the truth of the proposition is evident. We have found that (x—a)(a*3-{-p'x2 + q'x-f-r’) =0; and as a product becomes =0, when anyone of its factors=0, therefore the equation will have its conditions fulfilled, not only when x — a — 0, but also when xP-\-p x2-\-q’x -\-P — Q. Let us now suppose that & is a root of this equation; then, by reasoning exactly as in last article, and putting p' — b-\-p, q" — lr -\-pb -f- q\ we shall have a3 -\-px? -f- ((x 4 P — (x — b) (x2 -j-p'x 4 q") = 0. By proceeding in the same manner with the quadratic equation x2~j-p' x-\-q" z= 0, we shall find that if c denote one of its roots, then a2 4//' a4y" = (x — c) (x-\-c-\-p)”). So that if we put d — — (c4■i0,,)’ we xpJf-px? Jf-qx?-\-rx-\-s — (a—a) (a —£)(a— c) (a — d); and since each of the factors a — a, a — b, a — e, a — d may be assumed = 0, it follows that there are four different values of a, which will render the equation a44/>a34-g'a24-/'a-j-s — 0, namely, x — a, x ■=. b, x — c, x ~ d. The mode of reasoning which has been just now em¬ ployed in a particular case, may be applied to an equa¬ tion of any order whatever; we may therefore conclude, that every equation may be considered as the product of as many simple factors as the number denoting its order contains unity, and therefore, that the number of roots in any equation is precisely equal to the exponent of the highest power of the unknown quantity contained in that equation. 100. By considering equations of all degrees as formed from the products of factors x — a, x — b, x — c, &c. we discover curious relations, which subsist between the roots of any equation and its co-efficients. Thus, if we limit the number of factors to four, and suppose that a, b, c, d, are the roots of this equation of the fourth de¬ gree, xP-\-px?-\-qx?-\-rx-\-s — 0, we shall also have (* — a) (x — Z>)(# — q) (# — .'r3 4g'x24^4s~0, which we have considered as equal to {x—«) (a; — b) (x — c) (x — d) =0, may be formed of the product of two factors of the second degree, in these six different ways. By the product of (x — a) (x — b) and (x — c) (x—d), (x — a) ix — c) (x — b) ix — d), (x — a) (x— d) (x — b) (x — c), (x — b) (x — e) (x—a) (x—d), (x — b) (x—d) (x — a) (x — e). (x — e) (x —d) (x — a) (x—b). 4, X 3 Thus an equation of the fourth degree may have -—- = 6 quadratic divisors. By combining the simple factors three and three, we shall have divisors of the third degree, of which the num¬ ber for an equation of the nth order will be n(n — 1) — 2) , ^—2~~—g—-; and so on. 102. When the roots of an equation are all positive, its simple factors will have this form, x — a, x — b, x—cy &c.; and if, for the sake of brevity, we take only these three, the cubic equation which results from their product wall have this form, xz —px2 -{^qx — r— 0, wTherejo=a4^ + c> q—ab 4 ac+bc, r—abci and here it appears that the signs of the terms are 4 and — alternately. Hence we infer, that when the roots of an equation are all positive, the signs of its terms are positive and nega¬ tive alternately. If again the roots of the equation be all negative, and therefore its factors x-\-a, x + b, x-\-c, then p, q, and r being as before, the resulting equation will stand thus: x5 4 Px‘z + ^ + r=: 0- And hence we conclude, that when the roots are all ne¬ gative, there is no change whatever in the signs. 103. In general, if the roots of an equation be all real, that equation will have as many positive roots as there are changes of the signs from 4 to —> or from — 10 "h ’ and the remaining roots are negative. This rule, how¬ ever, does not apply when the equation has imaginary 1 ALGEBRA. 453 ljC ( rootS) unless such roots be considered as either positive ^/-y.w'or negative. > . That the rule is true when applied to quadratic equa¬ tions will be evident from Sect. IX. With respect to cubic equations, the rule also applies when the roots are cither all positive, or all negative, as we have just now shown. . . When a Cubic equation has one positive root, and the other two negative, its factors will be x — a, x-\-b, x-\-c, and the equation itself x?—a) —oil + ^ r x?—ac ^ x—abc— 0. + +bc) Here there must always be one change of the signs, since the first term is positive and the last negative ; and there can be no more than one ; for if the second term is negative, or b-\-c less than a, then (b-\-c)2 will be less than (b-\-c) a; but (b-\-c)2 is always greater than be, therefore be will be much less than a, or ab-\-ac, so that the third term must also be negative, and there¬ fore, in this case there can be only one change of the signs. If, again, the second term be positive, then, because the sign of the last term is negative, whatever be the sign of the third term, there can still be no more than one change of the signs. When the equation has two positive roots, and one negative, its factors are x-—a, x—b, x-\-c, and the equa¬ tion ar3—-{-abl —b > x?—acV x+abczzO. + e) —be) Here there must always be two changes of the signs ; for if «-f 6 be greater than c, the second term is negative, and the last term being always positive, there must be two changes, whether the sign of the third term be posi¬ tive or negative. If, again, a-\-bbe less than c, and there¬ fore the second term positive, it may be shown as before, that ai is much less than ac-\-bc; and hence the third term will be negative ; so that in either case there must he two changes of the signs. We may conclude, there¬ fore, upon the whole, that in cubic equations there are always as many positive roots as changes of the signs from -f to —, or from — to -f- ; and, by the same method ot reasoning, the rule will be found to extend to all equa¬ tions whatever. 104. It appears, from the manner in which the co¬ efficients of an equation are formed from its roots, that "hen the roots are all real, the co-efficients must consist entirely of real quantities. But it does not follow, on the contrary, that when the co-efficients are real, the roots are also real; for we have already found, that in a quadratic equation, a?-\-px-\-q=0, where p and q denote real quan¬ tities, the roots are sometimes both imaginary. ^ hen the roots of a quadratic equation are imaginary, they have always this form, a-J-V—Z/2, a—V—U2, which quantities may also be expressed thus, a b V —1, a—b v'-—1; so that we have these two factors x — a ^ ^ 1) x—a-\-b V—1, and taking their product, ir2—2ax + « + 0. 1 hus we see that two imaginary factors may be of such a orm as to admit of their product being expressed by a uu quantity; and hence the origin of imaginary roots in quadratic equations. h r* -' aPPea^s by induction, that no real equation can L oi med from imaginary factors, unless those factors be ta cu in pairs, and each pair have the form xz±za—bV—1, xz+za-\-bV—1; for the product of three, or any odd num- Algebra, ber of imaginary factors, whatever be their form, is still an imaginary quantity. Thus, if we take the product of any three of these four imaginary expressions, x+a+b V—\, x + a — bV—\, x + c + dV—T, x + c — dV^—i, we may form four different equations, each of which will involve imaginary quantities. If, however, each equation be multiplied by the remaining factor, which had not pre¬ viously entered into its composition, the product will be found to be rational, and the same for all the four. Hence we may deduce the three following inferences respecting the roots of equations : 1. If an equation have imaginary roots, it must have two, or four, or some even number of such roots. 2. If the degree of an equation be denoted by an odd number, that equation must have at least one real root. 3. If the degree of an equation be denoted by an even number, and that equation have one real root, it will also have another real root. 106. We shall now explain some transformations which are frequently necessary to prepare the higher orders of equations for a solution. Any equation may have its positive roots changed into negative roots of the same value, and its negative roots into such as are positive, by changing the signs of the terms alternately, beginning with the second. The truth of this remark will be evident, if we take two equations, (x—a)(x—5)(a?-|-c)=:0, (a; -f- «)(* -f- 6)(;r—c)=0, (which are such, that the positive roots of the one have the same values as the negative roots of the other), and multiply together their respective factors; for these equa¬ tions will stand thus: x?—a) -\-ab) —b > a?2—ac > x-\-abe—0, -|- c) - be) oft +n x?—ac /- x—abc=0 ; -e) -be) where it appears that the signs of the first and third terms are the same in each, but the signs of the second and fourth are just the opposite of each other. And this will be found to hold true, not only of cubic equations, but of all equations, to whatever order they belong. 107. It will sometimes be useful to transform an equa¬ tion into another that shall have each of its roots greater or less than the corresponding roots of the other equation, by some given quantity. Let (x — a)(a? — Z»)(a; c)=0 be any proposed equation which is to be transformed into another, having its roots greater or less than those of the proposed equation by the given quantity n; then, because the roots of the trans¬ formed equation are to be -\-azizin, z±zn, and —cz±zn, the equation itself will be (yz+zn — a)(yz+zn — b)(y=+zn -f- c)=0. Hence the reason of the following rule is evident. If the new equation is to have its roots greater than those of the proposed equation ; instead of x and its powers, substitute y — n and its powers : but if the roots are to be less; then, instead of x substitute 3/-f-M; and in either case, a new equation will be produced, the roots of which shall have the property required. 108. By the preceding rule, an equation may'be chang¬ ed into another, which has its roots either all positive, or all negative; but it is chiefly used in preparing cubic and biquadratic equations for a solution, by transforming them 454 ALGEBRA. Algebra, into others of the same degrees, but which want their second term. Let + ^ + be any cubic equation ; if we substitute y-j-wfor x, the equation is changed into the following: ty3_j_3n) 2 + +»3 1| + p\ y -\-2pn\y+Pn2\-Q + n-\-p-=:Q, or nz=. —^; for this assumption being made, and the value of n suusuuiieu. 2Z3 * +(?- ^),/+5£!_H+r_o; . P2 , ^o3 vq or, putting—-g- +q=q', and + ~ +r = /, the same equation may also stand thus, tf+q'y+r^o- 109. In general, any equation whatever may be trans¬ formed into another, which shall want its second term, by the following rule. Divide the co-efficient of the second term of the propos¬ ed equation by the exponent of the first term, and add the quotient, with its sign changed, to a new unknown quanti¬ ty ; the sum being substituted for the unknown quantity in the proposed equation, a new equation will be produc¬ ed, which will want the second term, as required. By this rule any adfected quadratic equation may be readily resolved; for by transforming it into another equa¬ tion which wants the second term, we thus reduce its solu¬ tion to that of a pure quadratic. Thus, if the quadratic equation a? — 5a;-j-6=:0 be proposed; by substituting y + i f°r xi we 7/2 T 5yi 25^ -5y-f [=0,or/- l=0. + 6 J Hence and since amy-f |, therefore = + 3, or + 2. 110. It has been shown (sect. 100) that in any equa¬ tion, the co-efficient of the second term, having its sign changed, is equal to the sum of all the roots; or, ab¬ stracting from their signs, it is equal to the difference be¬ tween the sum of the positive and the sum of the nega¬ tive roots : Therefore, if the second term be wanting, the sum of the positive roots in the equation must necessarily be equal to that of the negative roots. 111. Instead of taking away the second term from an equation, any other term may be made to vanish, by an assumption similar to that which has been employed to take away the second term. Thus, if in sect. 108 we as¬ sume 3n2 + 2j»»-|-§'=:0, by resolving this quadratic equa¬ tion, a value of n will be found which, when substituted in the equation, will cause the third term to vanish; and, by the resolution of a cubic equation, the third term may be taken away; and so on. 112. Another species of transformation, of use in the resolution of equations, is that by which an equation, having the co-efficients of some of its terms expressed by fractional quantities, is changed into another, the co-effi¬ cients of which are all integers. *0 Q V Let a;3+“ a: +- = 0 denote an equation to be so transformed, and let us assume y = abcx, and there¬ fore x = ; then, by substitution, our equation becomes^ el y3 p cPIPc* +«62C 2/+c -0; 'bn I " and multiplying the whole equation by a^e3, we have z/3 -j- bcpif -p dAb(?qy -j- c? d (?r — 0. Thus we have an equation free from fractions, while at the same time the co-efficient of the highest power of the unknown quantity is unity, as before. This transformation may always be performed by the following rule : Instead of the unknown quantity, substi¬ tute a new unknown quantity divided by the product of all the denominators ; then, by proper reduction, the equa¬ tion will be found to have the form required. If, however, the equation have this form, rr -p - — 0, 1 a 'a 1 a it will be sufficient to assume y — ax, and therefore x = - ; for then we have a a.!!- o a3+a3r+a2 2/+a-°’ and y3 -pjoy2 -p aqy -p dr — 0; which last equation has the form required. Sect. XI.—Of Cubic Equations. 113. Cubic equations, as well as equations of every higher degree, are,like quadratics,divided into two classes: they are said to be pure when they contain only one power of the unknown quantity ; and adfected when they contain two or more powers of that quantity. Pure cubic equations are therefore of this form, ad= 125, or a^zr — 27, or, in general, a?3 = r ; and hence it appears, that the value of the simple power of the un¬ known quantity may always be found without difficulty, by extracting the cube root of each side of the equation; thus, from the first of the three preceding examples we find a:zr -p 5, from the second, xz=. — 3, and from the third, 3 _ X ^ It would seem at first sight that the only value which x can have in the cubic equation or putting r-=.3-p.23-{-7,rz0. From the first, we find vz — — and «^23 zz — ; and from the second ^-f-23zz—r ; so that to determine the quantities and 2s, we have given their sum and pro¬ duct: now this is a problem which we have already re¬ solved when treating of quadratic equations ; and by pro¬ ceeding in the same manner in the present case, we shall find 23z= —ir—+ -|r2 ; ° 3 r='v/—+ + 2: and y—v-\-z 3 _______ 5 = '/—ir-fVs,773+ir2 -f-V—Lr^-V'zW + i7*- Ihus we have at last obtained a value of the unknown quantity y, in terms of the known quantities q and r; therefore the equation is resolved. 115. But this is only one of three values which y may have. Let us, for the sake of brevity, put 455 : V'—|r—V vW + lr2; A = — ^+^y3-f-ir2, B: and put /3= _1 + V—3 2 ’ _1_V—3 Then, from what has been shown (sect. 113), it is evident Algebra, that v and 2 have each these three values, 3 _ 3 _ 3_ v=VA, vzzaVA, v—j3VA ; 3_ 3 _ 3 _ Z=VB, z~a VB, 2zz/3 VB. To determine the corresponding values of v and 2, we must consider that «2 = — |- Vab": Now if we observe that a/3zz 1, it will immediately appear that v-J-2 has these three values, 3_ 3 _ v+z= Va +Vb, 3 _ 3 _ v-{-z=aVA +/5 Vb, 3 - 3 _ z>4-2zz/3v/A -fa Vb- Hence the three values of y are also these, 3__ 3_ yzzV'A-f-V'B, 3 _ 3 _ yzzaV A4-/5v'B, 3_ 3 _ _ ^ y=(3VA + aVB. The first of these formulae is commonly known by the name of Cardan’s rule ; but it is well known that Cardan was not the inventor, and that it ought to be attributed to Nicholas Tartalea and Scipio Ferreus, who discovered it much about the same time, and independently of each other. (See the Introduction^) The formulae given above for the roots of a cubic equa¬ tion may be put under a different form, and better adapt¬ ed to the purposes of arithmetical calculation as follows. “ therefore z— '— ? X = Because vz— 3’ 3? hence v-\-z— Va Va „ - Va’ thus it appears that the three values of y may also be expressed thus: 3 y=yA /X 3? Va 3y — 20=0, which being compared with the general equation, y3+qy+r=0, gives y=6, r— —20; hence A:=y—|r4-v/2i7yJ + 4r2 therefore the second formula of last article gives y= -—; but as this expression V10+Vi08 1 involves a radical quantity, let the square root of 108 be taken and added to 10, and the cube root of the sum V^ + v'108-: 456 ALGEBRA. found; thus we have 3jV/l0-|-V/108 = 2*732 nearly, 2 2 and therefore “ , =r — 0 — *732; hence we 3yiO+Vl08 at last find one of the values of y to be 2.732 — *732z=2. In finding the cube root of the radical quantity VlO + V108, we have taken only its approximate value, so as to have the expression for the root under a rational form, and in this way we can always find, as near as we please, the cube root of any surd of the form a-^-'Vb, where is a positive number. But it will sometimes hap¬ pen that the cube root of such a surd can be expressed exactly by another surd of the same form; and accord¬ ingly, in the present case, it appears that the cube root of lO-f-VlOS is 1 V3, as may be proved by actually raising 1 V3 to the third power. Hence we find 2 2 _ 2(1—V 3) V10+ VI08 “ 1+V3 ~ (1 — V3) (1 + V3) “ —^(1 — v'S); so that y = 1 V3 + 1 —V3 — 2, as be¬ fore. The other two values of y will be had by substituting ~ ^(j 1 V3 and 1 — V3 for VA and 3^7^ in the second and third formulae of last article, and restoring the values of a and |8. We thus have 3, = =ii^=2x (1 + V3)+x (1_V3) = -^1+ y= — ~ V/~- X (I + V3)+ -1+v'~3 x (1-V3) = __ 1 _ So that the three values of y are + 2, _1+ a/^4), —1— V—if; and since x—y— 1, the corresponding values of x are + 1, —2+ V—9, —2— V ^9. Thus it appears that one of the roots of the proposed equation is real, and the other two imaginary. The two imaginary roots might have been found other¬ wise, by considering that since one root of the equation is 1, the equation must be divisible by a: — I (sect. 99). Accordingly, the division being actually performed, and the quotient put =: 0, we have this quadratic equation, a^+Tr+lS — 0; which, when resolved by the rule for quadratics, gives x — — 2 rfc: V — 9, the same imaginary value as before. 117. In the application of the preceding formulae (sect. 114; and 115) to the resolution of the equation 'if-\rqy+ r — 0, it is necessary to find the square root of now, when that quantity is positive, as in the equation 6 3 therefore the roots of the equation are a . 90° — a -- — sin. 90° +a n x cos. g, n x sin. 3 • n x sin. 90° +a Let us next suppose that y3 — qy — r\& o. cubic equa¬ tion whose roots are required, and let us compare it with 3w2 X £ cos. a ; then it is 120. It is remarkable that the expression J a — 1-p^A—5 V— L and in general, * n J a— 1 a—5 V— 1, where n is any power of 2, admits of being reduced to another form, in which no impossible quantity is found. Thus, y« -p vdl _p Ja —b =^a + SVa2^, ■ 5V—1 = *)’ and Ja-p5 V— J [j2a -p 2V«2+52+2Va2-p52, 3S is easily proved by first raising the imaginary formu¬ la to the second and fourth powers, and then taking the S(luare and fourth root of each. But when n is 3, it does “ot seem that such reduction can possibly take place. u each of the surds be expanded into an infinite series, and their sum be taken, the imaginary quantity V—1 vanish, and thus the root may be found by a direct process. There are, however, other methods which seem pieferable. The following, which is derived from the cal¬ culus of sines, seems the best. 'b It will be demonstrated in Sect. XXV., that if a de- v'OL.

But from these two assumed equations we find y\q 2Vq /27 r2 S^V3 -#=—7=> cos. a——r—)J . = t= ; 3 V 3 n ^j3 2qV q and since the cosine of an arch cannot exceed unity, 27 r2 therefore — —- must be a proper fraction, that is, dy3 must exceed 27/’2, or -£j(f must exceed ^r2. If we now recollect that ^ is a negative quantity, it,will immediately appear that the proposed equation must necessarily be¬ long to the irreducible case. The rule, therefore, which we derive from the preced¬ ing analysis for resolving that case is as follows: Let y3 — qy=r be the proposed equation.

XII.—Of Biquadratic Equations. 122. When a biquadratic equation contains all its terms, it has this form, x4 + Ax3+B^+Ca; + Dz= 0, where A, B, C, D, denote any known quantities what¬ ever. We shall first consider pure biquadratics, or such as contain only the first and last terms, and therefore are of this form, x* = 54. In this case it is evident that x may be readily had by two extractions of the square root; by the first we find x* = b?, and by the second x — b. This, however, is only one of the values which x may have; for since x^ — 54, therefore cc4 — 64 — 0; but ar4 — 64 may be resolved into two factors x1 — 52 and a^-1-52, each of which admits of a similar resolution; for a?2 — S2 rz (x — b)(x-j-b) and x2 — b V—l) (x-\-bV—l)* Hence it appears that the equation x4 — = 0 may also h be expressed thus: (a: — b) (x + b) (x — b V—l) =0; so that x may have these four values, ibra. +5, —b, -\-bV—1, —bV—1, two of which are real, and the others imaginary. 123. Next to pure biquadratic equations, in respect of easiness of resolution, are such as want the second and fourth terms, and therefore have this form, a^1 + qx? + s m 0. These may be resolved in the manner of quadratic equa¬ tions ; for if we put y2 — x?, we have if+qy+s - 0, Q ■ ^qI _ - from which we find y — ——— , and therefore = H-./—? — ^ 124. When a biquadratic equation has all its terms, the manner of resolving it is not so obvious as in the two former cases, but its resolution may be always reduced to that of a cubic equation. There are various methods by which such a reduction may be effected. The follow¬ ing, which we select as one of the most ingenious, was first given by Euler in the Petersburg Commentaries, and afterwards explained more fully in his Elements of Algebra. We have already explained, sect. 109, how an equation which is complete in its terms may be transformed into another of the same degree, but which wants the second term; therefore any biquadratic equation may be reduced to this form, where the second term is wanting, and where p, q, r, de¬ note any known quantities whatever. That we may form an equation similar to the above, let us assume Va-f- Vb+Vc, and also suppose that the letters a, b, c, denote the roots of the cubic equation P22-kQz—11=0 ; then, from the theory of equations we have a-j-5-j-c=—P, ab+ac+bc=zQ,, abc—R. We square the assumed formula y — Vc, and obtain y2— a-k5-|-c-k2 (Va5-|- Vac-f- Vbcf, or, substituting — P for a 6 + £, and transposing; y2~tfYz=.2(yab-^-Vac^. Vbc). Let this equation be also squared, and we have y4 + 2Py2 + P2 = 4 (ab + ac+ be) + 8 + vW -kVaic2); and since aS-kac-k&crrQ, and Va2bc-\-Val/c-\-yabc2— Vabc (Va+V5+ V the same equation may be expressed thus: y4+2Py2+F=4Q+Sv'Ky. Thus we have the biquadratic equation y4 + 2Yif — 8 VRy+P2—4Q=0, one of the roots of which isyzr Va-f-Vb -\-Vc, and which a, b, c, are the roots of the cubic equation -\-Qz — RzrO. . 125. In order to apply this resolution to the propose equation yi-{-py2A'qy-{-r=Q> we noust express the as sumed co-efficients P, Q, R, by means of p, q, r, the co 1 ALGEBRA. AW* _ efficients of that equation. For this purpose, let us com- vv^pare the equations ?/4-f2P^2 — 8 VR y+P2 — 4Q=0, and it immediately appears that 2P = j9,—— p —4Q = r; and from these three equations we find f) o2—4?" (P1 P= Q = —rs-’ R = ET- Hence it follows that the 459 16 R -21. “ 64 roots of the proposed equation are generally expressed by the formula y = Va-F'V/6-j-V/e; where a, 6, c, denote the roots of this cubic equation, ^2 ^ 16 4r .£. = 0. 64 But to find each particular root, we must consider, that as the square root of a number may be either positive or nega¬ tive, so each of the quantities Va, V/v, Vc, may have either the sign + or— prefixed to it; and hence our formula will give eight different expressions for the root. It is, however, to be observed, that as the product of the three quantities V«, s/\ Vc, must be equal to VR or to — 2, when q is 8 1 positive, their product must be a negative quantity ; and this can only be effected by making either one or three of them negative ; again, when q is negative, their product must be a positive quantity; so that in this case they must either be all positive, or two of them must be negative. These considerations enable us to determine, that four of the eight expressions for the root belong to the case in which q is positive, and the other four to that in which it is negative. 126. We shall now give the result of the preceding in¬ vestigation in the form of a practical rule ; and as the co¬ efficients of the cubic equation which has been found in¬ volve fractions, we shall transform it into another, in which the co-efficients are integers, by supposing Thus the equation z2+ qp—4r 16 q2 ■—=0 becomes, after reduction, v3+2pP + (p2—4r>—; it also follows, that since the roots of the former equation are a, b, c, the roots of the latter are |, |, so that our rule may now be expressed thus : Let 3^-j-py2+be any biquadratic equation wanting its second term. Form this cubic equation, v3-j- 2pv2 (jo2—ir)v—y2—0, and find its roots, which, let us denote by a, b, c. are hen the 100tS the ProPose^ biquadratic equation when^ is negative, y=Kv'«+/v/6-f-Vc), y~\ 0,—v b—v an equation of the same kind as the former. 131. That we may effect the proposed transformation upon the equation cX/ "I" “"i A __ \_fj ^ let every two terms which are equally distant from the^ extremes be collected into one, and the whole be divided Vvtt m2 +rw"»v» ton I'V' by x?, then *2+^r+7?O+:|;)+7=0- Let us assume #+-=z; x then ir2+2-j--^-=2;2, and x?-{--^=z2 — 2. Thus the equation «2 + -^-+p(^ + ^) + g,=0, becomes «2+p^+g' — 2=0; and since z+-=z, therefore xs—sa;4-l=0. 1 x Hence, to determine the roots of the biquadratic equa¬ tion ofi^pxP + qoP-^-px-^-1=0, we have the following rule : Form this quadratic equation, z2-{-pz-{-q — 2=0, and find its roots, which, let us suppose denoted by ^ and z? ; then the four roots of the proposed equation will be found by resolving two quadratic equations, viz. a? — z'a;-|-l=0, x? — s"#+l=0. 132. It maybe observed, respecting these two quadra¬ tic equations, that since the last term of each is unity, if we put a, a' to denote the roots of the one, and b, U those of the other, we have, from the theory of equations, a ci = 1, and therefore a'=—; also b &'=!, and Uzz\: now a, a o a', b, b' are also the roots of the equation ^-{-pxP + qx2 -{-px-{-1=0. Hence it appears that the proposed equation has this peculiar property, that one half of its roots are the reci¬ procals of the other half; and to that circumstance we are indebted for the simplicity of its resolution. 133. The following equation, x6 -{-px^ qxx rx? -j- qx? -\-px -f 1=0, which is of the sixth order, admits of a resolution in all respects similar to the former; for, by putting it under this form, +* (*+j) +,'=0, and putting also x so that x2—zx-^-l — 0, we have x2 — % ^ — 3(x+ ^)=2r3 ^z' Hence, by substitution, the proposed equation is trans¬ formed into the following cubic equation, z?-{-pz2-{-(q — 3)z-{-7’ — 2p=0; therefore, putting z', z", zf", to denote its roots, the six roots of the proposed equation will be had by resolving these three quadratics, ic2 — z'a;-1-1=0, x? — z'rx-{-lzz0, x? — and here it is evident, as in the former case, that the roots of each quadratic equation are the reciprocals of eac other, so that the one half of the roots of the propose equation are the reciprocals of the other half. The method of resolution we have employed in thetvio preceding examples is general for all equations whate''er> in which the terms placed at equal distances from the rs ALGEBRA. 461 an(l iast have the same co-efficients, and which are called reciprocal equations, because any such equation has the same form when you substitute for x its reciprocal, 134. If the greatest exponent of the unknown quantity in a reciprocal equation is an odd number, as in this example, - . x> qz? -if qx? ^.px lz=0, the equation will always be satisfied by substituting — 1 for x; hence, — 1 must be a root of the equation, and therefore the equation must be divisible by Ac¬ cordingly, if the division be actually performed, we shall have in the present case (p — l)^3 — ^1)^+(p — 1>+1=0, another reciprocal equation, in which the greatest expon¬ ent of a; is an even number, and therefore resolvable in the manner we have already explained. 135. As an application of the theory of reciprocal equa¬ tion, let it be proposed to find x from this equation, m5-]-1 (i+Ty5-0'’ where a denotes a given number. Every expression of the form xn + 1 is divisible by a?-|-1 when n is an odd number. In the present case, the nume¬ rator and denominator being divided by #+1, the equa¬ tion becomes . tr4—ar3-}-#2 — m+1 _ 6a^4-4«-f-\~a’ and this again, by proper reduction, (a—l)a^+(4aq- —l)a^-j-(4a+ l)a;4-a—1=0; . . +1 6® — 1 and, putting p = q = 1 = 0; a reciprocal equation, resolvable into two quadratics. Sect.XIV.—Of Equations which have Equal Roots. 136. When an equation has two or more equal roots, these may always be discovered, and the equation reduc¬ ed to another of an inferior degree, by a method of resolu¬ tion which is peculiar to this class of equations. Although the method of resolution we are to employ will apply alike to equations of every degree, having equal roots, yet, for the sake of brevity, we shall take a bi¬ quadratic equation, a4 -fpar3 -f- qx2+ra? -f- s= 0, the roots of which may be generally denoted by a, b, c, and d. Thus we have, from the theory of equations, {x—a)(x — &)(,r—c)(x — 6?)=x4 -{-pcfi qx2 -{- rx + 5=0. Let us put A = (x — a)(x — b)(x — c), A" = (x — a)(x — c) (x—d), A—(x — a)(x — b)(x —d), Am=(x—b)(x — e)(x—d): then, by actual multiplication, we have A =ar3—aA -f-r/A4 —b > afi+acV x — abc, -A +bc) A' —a?—al } —& f ofi-Jf-adp x — abd, —d) +bd) A"—x?—oA —c V xt+adV x — acd, —d} -\-bd) A'"=d?—b'l +bc^ —cycp+bdyx — bed; —d y -}■ Cflf j and taking the sum of these four equations; A + A' + A" + A'"=4«3—3a ^ +2ab' v_ -f" 2o!c —abc —3c f 4- I —abd —3dj -j- 2bc x—acd -j- ^J)d —bed. \-2cd ^ But since a, b, c, d are the roots of the equation x4 -f-px3 + qx2 4- xx 4- 5= 0, we have —3{a-\-b-\.c-Jrd)z-3p, 2(a&4-ac 4-ac?4-ic4-ic?4-cc?)=25', —(abc 4- abd 4- acd 4- bed)—r; therefore, by substitution, A 4- A' 4- A" 4- A'"—4X3 4- Bpx2 4- ~qx 4- x. Algebra. 137. Let us now suppose that the proposed biquadratic equation has two equal roots, or a—b; then x—a—x—b, and since one or other of these equal factors enters each of the four products A, A!, A!', A'", it is evident that A4-A'4-A"4-A"', or 4x3 4- Spx3 4- 2qx 4. r must be divisi¬ ble by x—a, or x—b. Thus it appears that if the pro¬ posed equation x4 4-px3 4-^x2 4-xx 4-0 have two equal roots, each of them must also be a root of this equation, 4X3 4-Spx2 4-S^x 4-x=0; for when the first of these equations is divisible by (x—of; the latter is necessarily divisible by x- -a. 138. Let us next suppose that the proposed equation has three equal roots, or a—b—c; then, two at least of the three equal factors x—a, x—b, x—c, must enter each of the four products A, A', A", A!"; so that in this case, A4-A'4-A"4-A'", or 4x34-3x24-2§'x4-x, must be twice divisible by x—a. Hence it follows, that as often as the proposed equation has three equal roots, two of them must also be equal roots of the equation 4x3 4- Spx2 4- 2—<7+r are formed from the proposed equa¬ tion a?+joa?+5'a;+7’ by substituting successively -H and —1 for x. \1£rf a. Now the values of x are some of the divisors of r, which is the term left in the proposed equation, when x is sup¬ posed = 0; and the values of y are some of the di¬ visors of l-\-p+q+r and —1 + —q-\-r respectively; and these are in arithmetical progression, increasing by the common difference, unity; because x—1, #, #+1, are in that progression ; and it is obvious that the same rea¬ soning will apply to an equation of any degree whatever. Hence the following rule : Substitute in place of the unknown quantity, succes¬ sively, three or more terms of the progression 1, 0, —1, &c. and find all the divisors of the sums that result; then take out all the arithmetical progressions that can be found among these divisors, whose common difference is 1, and the values of x will be among these terms of the progressions, which are the divisors of the result arising from the substitution of ^—0. When the series increases, the roots will be positive; and when it decreases, they will be negative. Ex. 1. Let it be required to find a root of the equation $—3?—Kte-f- 6=0. ALGEBRA. or UOy—384-0, Substit. Result. x= + l ( x= 0*| x=—1 ( a?— —10a;-[-6 H — 4 + 6 + 14 Divisors. 1. 2. 4. 1. 2. 3. 6. 1. 2. 7. 14. Prog. In this example there is only one progression, 4, 3, 2, the term of which opposite to the supposition of a;=:0 being 3, and the series decreasing, we try if —3 substi¬ tuted for x makes the equation vanish; and as it succeeds, it follows that —3 is one of its roots. To find the re¬ maining roots, if x3—x2—10a;+6 be divided by a;+3, and the quotient a.12—4a;+2 put =0, they will appear to be 2+^/2, and 2—V2. Ex. 2. Let the proposed equation be a^ + ar3—29a?—9a;+180=0. To find its roots. I- _ one root of which is y=3; hence a;=^=l The proposed equation being now divided by a;—£ ;s rp_ duced to tins quadratic, a?—a:+ 8=0, the roots of’which are both impossible. 148.. When the co-efficients of an equation are integers and unity that of the highest power of the unknown quan¬ tity, if its roots are not found among the divisors of the last term, we may be certain that, whether the equation be pure or adfected, its roots cannot be exactly express¬ ed either by whole numbers or rational fractions. This may be demonstrated by means of the following proposi¬ tion. If a prime number P be a divisor of the product of two numbers A and B, it will also be a divisor of at least one of the numbers. Let us suppose that it does not divide B, and that B is greater than P ; then, putting g for the greatest number of times that P can be had in B, and B' for the remainder, we have p^+p-, and therefore AB AB' P -?A + -p-- Hence it appears, that if P be a divisor of AB, it is also a divisor of A B'. Now B' is less than P, for it is the remainder which is found in dividing B by P ; therefore seeing we cannot divide B' by P, let P be divided by B'’ and y put for the quotient, also B" for the remainder! I3™,,1?1' p !'e by B", and g" put for the quotient, and B for the remainder, and so on; and as P is sup¬ posed to be a prime number, it is evident that this se¬ nes of operations may be continued till a remainder be found equal to unity, which will at last be the case ; for the divisors are the successive remainders of the divisions, and therefore each is less than the divisor which preceded it. By performing these operations, we obtain the follow¬ ing series of equations; Sub. Res. 70 144 180 160 90 F=g' B' +B", Divisors. 1. 2. 5. 7. 10. 14. 35. 70. L 2. 3. 4. 6. 8. 9. 12, &c.

Here there are four progressions, two increasing and two n2as!ng;,hence’by taking their terms’ which are °p- posite to the supposition of a;=0, we have these four +3> +4, —3, —5, to be tried as roots of the ^all of which are found to succeed. be a frit,-n"7 °1the c°-?fficients of the proposed equation Other b1- ’ ^he e(luatlon maybe transformed into an- aml tbhaVmf ‘I16 c°-efficient of the highest power unity, hose of the remaining terms integers by sect. 112 tho^e^ofTl018 0t the t.ransformed equation being found! from them ^ pr0p0Sed e(luatlon may be easily derived Tor example, if the proposed equation be x3 ^ 6—0, let us assume Thus the equation is transformed to 64 64”*" 16 6~°’ ^AB' AP—AB" A AB" P - P -A p~- Now, if AB be divisible by P, we have shown that AB', and consequently y'AB', is divisible by P; therefore, from the last equation, it appears that AB" must also be divi¬ sible by P. Again, from the preceding series of equations, we have AP—AB'" , , „ AB = — , and therefore <7"AB" AP—AB'" . AB'" ~p~=—p—=A— -p-; hence we conclude that AB'" is also divisible by P. Proceeding in this manner, and observing that the series of quantities B', B", B'", &c. continually decrease till one of them =1, it is evident that we shall at last come to a product of this form, A X 1, which must be di¬ visible by P, and hence the truth of the proposition is manifest. 149. It follows from this proposition, that if the prime number P, which we have supposed not to be a divisor of 464 Algebra. ALGEBRA. B, is at the same time not a divisor of A, it cannot be a > divisor of AB, the product of A and B. Let - be a fraction in its lowest terms, then the num- a bers a and b have no common divisor; but from what has been just now shown, it appears, that if a prime number be not a divisor of a, it cannot be a divisor of « X a or ^’ and in like manner, that if a prime number is not a divi¬ sor of 5, it cannot be a divisor of & X 6, or Z*2; therefore it is evident that a2 and l? have no common divisor, and thus the fraction —r is also in its lowest terms. az Hence it follows that the square of any fractional quan¬ tity is still a fraction, and cannot possibly be a whole num¬ ber; and, on the contrary, that the square root of a whole number cannot possibly be a fraction; so that all such whole numbers as are not perfect squares can neither have their roots expressed by integers nor by fractions. Seeing that if a prime number is not a divisor of «, it is also not a divisor of «2; therefore, if it is not a di¬ visor of a, it cannot be a divisor of a x a2 or a3 ; and by reasoning in this way, it is obvious that if a prime number is not a divisor of a, it cannot be a divisor of an ; also, that if it is not a divisor of Z», it cannot be a divisor of bn there- h bn fore if - is a fraction in its lowest terms, — is also a frac- a a tion in its lowest terms; so that any power whatever of a fraction is also a fraction ; and on the contrary, any root of a whole number is also a whole number. Hence it fol¬ lows, that if the root of a whole number is not expressible by an integer, such root cannot be expressed by a fraction, but is therefore irrational or incommensurable. 150. Let us next suppose that xn _j. p^w-i Qxn-2 I- Ttf+U=0 is any equation whatever, in which P, Q, &c. denote integer numbers ; then, if its roots are not integers, they cannot possibly be rational fractions. For, if possible, let us sup¬ pose a fraction reduced to its lowest terms ; then, by substitution, nn /7«—1 nn~% ft, £ + Pf=i+ai»- + T5+U=0; and, reducing all the terms to a common denominator, an + Van~lb + Qan~W... + Tabn~x + UZ»n=0; which equation may also be expressed thus, . an + b(Van~l + Qan-2b2... + Tabn-2 + where the equation consists of two parts, one of which is divisible by b. But by hypothesis a and b have no com¬ mon measure, therefore an is not divisible by b, sect. 149 ; hence it is evident that the two parts of the equation can¬ not destroy each other as they ought to do; therefore x cannot possibly be a fraction. Let the proposed equation be A, ot?—5a;2-}-Kte—15=0, 01) which, by collecting the positive terms into one sum, and the negative into another, may also be expressed thus, ^4- 10a; — (5a;2 +15)=0 ; then, to determine a root of the equation, we must find such a number as, when substituted for x, will render ar5-!- 10a;=5a;2 -j-15. Let us suppose x to increase and to have every degree of magnitude, from 0 upwards in the scale of number; then a-3-!- 10a? and 5a2+15 will both continually increase, but with different degrees of quickness, as appears from the following table. Successive values of a?; 0, 1, 2, 3, 4, 5, 6, &c. of 10a;; 0, 11, 28, 57, 104, 175, 276, &c. of 5a?+15; 15, 20, 35, 60, 95, 140, 195, &c. By inspecting this table, it appears that while x increases from 0 to a certain numerical value, which exceeds 3, the positive part of the equation, or a3+ 10a?, is always less than the negative part, or 5x>+15; so that the expression a?3+ 10a; — (Sa^+lS) or a? — 5a?+10a;—15 must necessarily be negative. It also appears, that when x has increased beyond that numerical value, and which is evidently less than 4, the positive part of the equation, instead of being less than the negative part, is now greater, and therefore the expression a^— 5a?+ 10a:— 15 is changed from a negative to a positive quantity. Hence we may conclude that there is some real and determinate value of a?, which is greater than 3, but less than 4, and which will render the positive and negative parts of the equation equal to one another; therefore that value of x must be a root of the proposed equation; and as what has been just now shown in a particular case will readily apply to any equation whatever, the truth of the proposition is obvious. 152. Two limits, between which all the roots of any equation are contained, may be determined by this other proposition: II. Let N be the greatest negative co-efficient in any equation. Change the signs of the terms taken alternately, beginning with the second, and let N' be the greatest ne¬ gative co-efficient after the signs are so changed. Ihe positive roots of the equation are contained between 0 and N + l, and the negative roots between 0 and —N' !• Suppose the equation to be —Jpx3+<73?2 — rx — 5=0, which may be also expressed thus: Then, whatever be the values of the co-efficients p, ty r> &c. it is evident that x may be taken so great as to render Sect. XVI.—Resolution of Equations by Approxi¬ mation. 151. When the roots of an equation cannot be accurate¬ ly expressed by rational numbers, it is necessary to have recourse to methods of approximation; and by these we can always determine the numerical values of the roots to as great a degree of accuracy as we please. The application of methods of approximation is rendered easy by means of the following propositions : I. If two numbers, either whole or fractional, be found, which, when substituted for the unknown quantity in any equation, produce results with contrary signs, we may conclude that at least one root of the proposed equation is between those numbers, and is consequently real. ■ as small as we please, P, <1 __ I—i-, less • • P Q each of the quantities : ~ and therefore their sum, or —^+^ — ^ than 1; but in that case the quantity K1 - ora?4—jo^+^a?2—rx-\-s, will be positive, and such, that the first term x is gre than the sum of all the remaining terms; there oie a a?4+5,a?2, the sum of the positive terms, will be greater than jsa;3+ra?+5, the sum of the negative e Hence it follow's, that if a number be found, substituted for x, renders the expression J ery — rx — s positive, and which is also such, tna ALGEBRA. , )ra. greater number has the same property, that number will exceed the greatest positive root of the equation. Now, if we suppose N to be the greatest negative co¬ efficient, it is evident that the positive part of the equa¬ tion, or ar*-}-^2, is greater than px5 +rx-\-s, provided + 26*087 + 46*172?/, &c. — 4^=—46*172 —61*291/, &c. — 3*=— 6*780— 3?/ + 27 =+27 tion, or ar-f-yx , is greaier man px~ -\-rx-^-s, provided — thatar4 is greater than N a;3 + Na;2 + Na?+N, or N (3^+ 0 = *135 i ‘ISS ^2+3;+1); but x3 + x'2 + x +1—J, therefore a Hence y=j^-^=*0075, and a;=2*26+y=2*2675. This 18*119y nearly. positive result will be obtained, if for x there be substitut- ed a number such that ^ 1*’ or ^ x4 — N. Now this last condition will evidently be fulfill¬ ed if we take x5—ai^Na?4, and from this equation we find a=N+l; but it further appears that the same condition will also be fulfilled as often as a?5 — a^^Nar4, or a? •— 1 -^N, that is, xz^N-\-1, therefore N+1 must be a limit to the greatest positive root of the proposed equation, as was to be shown. If—y be substituted for +a?, the equation a4—px3 +ya2 — rx—s=0 will be transformed into ]^-\-py3 +ry — s=0; which equation differs from the former only in the signs of the second, fourth, &c. terms; and as the posi¬ tive roots of this last equation are the same as the nega¬ tive roots of the proposed equation, it is evident that their limit must be such as has been assigned. 153. From the two preceding propositions it will not be difficult to discover, by means of a few trials, the nearest integers to the roots of any proposed numeral equation; and those being found, we may approximate to the roots continually, as in the following example : a/ — 4a;3 * —3.r+27=Q. Here the greatest negative co-efficient being 4, it follows, sect. 152, that the greatest positive root is less than 5. If — y be substituted for a?, the equation is transformed to y4 + 4y3 * + 3y + 27=0, an equation having all its terms positive; therefore it can have no positive roots, and consequently the proposed equation can have no negative roots : its real roots must therefore be contained between 0 and + 5. To determine the limits of each root in particular, let 0, 1, 2, 3, 4, be substituted successively for x ; thus we obtain the following corresponding results : Substitutions for x, 0, 1, 2, 3, 4, Results, + 27, + 21, +5, — 9, +15. Hence it appears that the equation has two real roots, one between 2 and 3, and another between 3 and 4. That we may approximate to the first root, let us sup¬ pose x=2+y, whereby is a fraction less than unity, and therefore its second and higher powers but small in com¬ parison to its first power: hence, in finding an approxi¬ mate value ofy, they may be rejected. Thus we have a4= +16 + 32y, &c. — 4x,3=—32 — 48y, &c. — 3x =— 6— 3y + 27 = + 27 value of x is true to the last figure, but a more accurate value may be obtained by supposing #=2*2675+y", and finding the value of y" in the same manner as we have already found those of ?/ and y ; and thus the approxi¬ mation may be continued till any required degree of ac¬ curacy be obtained. The second root of the equation, which we have^ al¬ ready found to be between 3 and 4, may be investigated in the same manner as the first, and will appear to be 3*6797, the approximation being carried on to the fourth figure of the decimal, in determining each root. 154. In the preceding example we have shown how to approximate to the roots of an adfected equation; but the same method will also apply to pure equations. For example, let it be required to determine x from this equation, #-3=2. Because x is greater than 1 and less than 2, but nearer to the former number than to the latter, let us assume x= 1 +y S tlien> rejecting the powers of y which exceed the first, we have #3=l+3y, and therefore 2=l + 3y, and ?/=J-=*3 nearly; hence #=1*3 nearly. Let us next assume #=1*3 + ?/, then, proceeding as before, we find 2=2*197+ 5*07y, hence y= =—*039, and #=1*3 — *039=1*26 nearly. To find a still nearer approximation, let us suppose #= 1*26+y, then, from this assumption we find y = —*000079, and therefore #=1*259921, which value is true to the last figure. 155. By assuming an equation of any order with literal co-efficients, a general formula may be investigated for approximating to the roots of equations belonging to that particular order. Let us take for an example the cubic equation #3+j»#2+y# + 7*= 0, and suppose that #=a+y, where a is nearly equal to #, and y is a small fraction. Then, by substituting «+y for # in the proposed equation, and rejecting the powers of y which exceed the first, on account of their smallness, we have d? +jpa2 + yr/ + r + (3a2 + 3y« + q)y— 0. Hence y=- 5!+/^+7«+’' and ^ Hence 0= 5—19y nearly, and yr;—-..gQ. therefore, for a first approximation we We «=2*26. Let us next suppose #=2*26+y'; then, rejecting as be- ?re t*,e second and higher powers of y on account of eir smafiness,and retaining three decimal places, we have 3a2 + 2j»a + g' ’ a3 + joa2 + + ?* 2a3 +y>«2 — r 3a2 + 2pa + q — 3a2 + *2y?o! + / Let it be required to approximate to a root of the cubic equation #3 + 2#2 + 3# — 50=0. Here/>=2, y=3, and r— — 50; and by trials it appears that # is between 2 and 3, but nearest the latter number; therefore, for the first approximation, a may be supposed =3, hence we find r 2«3+/>«2 r 122 r, i — 3a2 + 2jt?a + $' ^ 21" By substituting for a in the formula, and proceeding as The anS „ "" Sl^ denotes that the quantities between which it is placed are unequal. •^L c, that a is less than c. V0L. II. Thus a 6 signifies that a is greater than b. 3 N 466 ALGEBRA. Algebra, before, a value of x would be found more exact than the 'former, and so on we may go as far as we please. 156. The method we have hitherto employed for ap¬ proximating to the roots of equations is known by the name of the method of successive substitutions, and was first proposed by Newton. It has been since improved by Lagrange, who has given it a form which has the advan¬ tage of showing the progress made in the approximation by each operation. This improved form we now proceed to explain. Let a denote the whole number next less to the root changes of the signs, it follows that the equation Ale positive roots, one between 1*2 and 1-4, and an-^ 1 sought, and - a fraction, which, when added to a, com- V pletes the root; then x—a-f-j If this value of x be sub¬ stituted in the proposed equation, a new equation involv¬ ing y will be had, which, when cleared of fractions, will necessarily have a root greater than unity. Let b be the whole number which is next less than that root; then, for a first approximation, we have x— here two has two positive other between L6 and 1'8. Hence it appears, that to find either value of x, we may assume a;=l4--; then, by substitution, we have y S'3 —%2+%+1=0- The limit of the positive root of this last equation is 5, and by substituting 0, 1, 2, 3, 4, successively for y, it will be found to have two, one between 1 and 2, and the other between 2 and 3. Therefore, for a first approximation, we have £=1+^, that is, x—% xz=\. To approach nearer to the first value of y, let us take yz=. 1 -j—and therefore But b being only an approximate value of y, in the same manner as a is an approximate value of x, we may suppose then, by substituting £+- for y, we shall have a new equation, involving only f, which must be greater than unity. . Putting therefore bi to denote the next whole number less than the root of the equation in¬ volving y, we have yz=.b-\--^-=.—and substituting this value in that of x, the result is b' x—af- bb'Jf 1 for a second approximate value of x. To find a third value, we may take yt—b'-\- — \\hen if 5" denote the next whole number less than we have , 7, 1 b'b"+\ . y =^+jr= ^ ■> whence , b" bb'V'+b"+b . 2'=S+W4TL=-6^I-’ and b'b"+\ x-a+bb'b"+b" Jf-V and so on, to obtain more accurate approximations. We shall apply this method to the following example: a? —7*-}-7=0. Here the positive roots must be between 0 and 8; let us to 8, and 7, 8, therefore substitute successively, 0, 1, 2, we obtain the following results : Substitutions. 0, 1, 2, 3, 4, 5, 6, Results. + 7, +1, +1, +13, +43, +97, +181, +301, +463. But as these results have all the same sign, nothing can be concluded respecting the magnitude of the roots from that circumstance alone. It is however observable, that while x increases from 0 to 1, the results decrease; but that whatever successive magnitudes x has greater than 2, the results increase. We may therefore reasonably con¬ clude, that if the equation have any positive roots, they must be between 1 and 2. Accordingly, by substituting P2, P4, T6, and T8, successively for x, we find these re¬ sults, + *328, —-056, —T04, +*232; and as there are ys _ sya _y+i-o. This last equation will be found to have only one real root between 2 and 3 ; from which it appears that y= l+£=f, and a?=l + f=f. Let us next suppose y=2 + —; hence we find y"3 _ 3y"2 _ 4y' — 1=0, and from this equation, y" is found to be between 4 and 5. Taking the least limit we have y=2+£=f, y=l+$=^, x=l+fj=f§. It is easy to continue this process, by assuming f= 4+p and so on, as far as may be judged necessary. We return to the second value of x, which was found = | by the first approximation, and which corresponds to y=2. Putting y=2 +and substituting this value in the equation y3 — 4 &c- ^ave rc101,6 one r<>ot greater than unity, and from each root a series of equations may be derived, by which we may approximate to the particular roots of the proposed equation contained between the limits a and a + 1. Sect. XVII.—Of Intinite Series. 158. The resolving of any proposed quantity into a series, is a problem of considerable importance in the application of algebra to the higher branches of the ma¬ thematics; and there are various methods by which it may be performed, suited to the particular forms of the quantities. Any rational fraction may be resolved into a series, by the common operation of algebraic division, as in the fol¬ lowing examples : ax Ex, 1.

Ex. 2. By a like process we find a2 .-1 &c (a+a)2 os4 the law of continuation being evident. 159. A second method by which algebraic quantities, "hether rational or irrational, may be converted into series, and which is also of very extensive use in the uglier parts of the mathematics, consists in assuming a senes with indeterminate co-efficients, and having its terms arranged according to the powers of some quantity contained in the proposed expression. That we may explain this method, let us suppose that the fraction ——— a,2 -t-ax-t-x'2 pioceeding by the powers of x. assume a2 hff 'ffoidw lo fbfiO lo goulnv -w:,, - ; . = A + Bai+C^ + D^+Ear4-}-, &c. where A denotes those terms of the series into which x ocs not at enter, Bx the terms which contain only the first power of *, Cx2 the terms which contain only Algebra, the second power, and so on. Let both sides of the' equation be multiplied by a2 + ax+x“, so as to take away the denominator of the fraction, and let the nume¬ rator a2 be transposed to the other side, so that the whole expression may be rr 0; then is to be converted into a series We are therefore to a2 A + a2B 1 — a2+aAj +a2C) +a2D) +«2E) + a B a2 +a C >- a2 -f « D >- a4, &c. = 0. + A) + c) + B) Now the quantities A, B, C, D, &c. being supposed to be entirely' independent of any particular value of x, it follows that the whole expression can only be = 0, upon the supposition that the terms which multiply the same powers of x are separately = 0; for if that were not the case, it would follow that x had a determinate relation to the quantities A, B, C, &c. which is contrary to what we have supposed. To determine the quantities A, B, C, &c. therefore, we have this series of equations, «2A — a2 =0, henceA^= 1; a2B-j-«A — 0, «2C + aB + A=0, «2D + aC + B=:0, B = xoiijqe . C = D- 201 nova E a JB a a D a &c. a2 _B d2 n'£ ■— 0 1 «2 E -j- dD C rr 0, &c. ‘ Here the law of relation which takes place among the quantities A, B, C, D, &c. is evident, viz. that if P, Q, R denote any three co-efficients which immediately follow' each other, «2 R + aQ + P— 0; and from this equation, by means of the co-efficients al¬ ready determined, we find F = 0, G z= -4-, H = —, a6 o7’ K=0, &c.

For this purpose we might assume • Va2 — ^irA + Bic+C^+D^+Eir4-}-, &c.; but as we would then find the co-efficients of the odd powers of x to be each z= 0, let us rather assume Va2 — x2 = A + Bx2 + Cdl + D3fi + , &c. then, squaring both sides, and transposing, we have ' A2+2AB) +2AC) +2AD) a + Hence A2 — a2 2AB+1 n&ftj B.Grf 2AC + B2 1> x2 ) + B2) +2BC rrO, and A—a ; 1 a?6-f-, &c. ‘J3V9\ =0, :0, vm AD + BC =0, D= &c. &c, 1 "2A' B2 2A : BC ' A : OgO* c= 1_ 2a J_ 8a3 ’ 1 16a5’ 468 ALGEBRA- Algebra, and substituting for A, B, C, &c. their values; Va2—x‘2—a— — 2a a?4 8^ 16a5 &c. from these equations, and divide each term of the series Ala by the denominator —-2;, we have ‘-fa m—2- -f UVm~2 -f T)7"—1 , , „ . . . . • £ M”-1 JL-Un-<2V. . . -f '«Vn“2 4-Vn ' This method of resolving a quantity into any inhmte - Ln/„3 .,0, , „ « , „ series will be found more expeditious than any other, as "J" 2^ jl often as the operations of division and evolution are to be z . /"h’ performed at the same time, as in these expressions, Now, as this last equation must be true, whatever be the values of y and z, we may suppose »/=z, but in that -r or Vaq—-a;2 Va2 -f x'2 v a3-far5 case l-fyrrl+z, or unz=.vn, and therefore u=.v.

The binomial theorem affords a third method of ^ . 2By+3Cv2+4D?/+5E?/-f, &c. resolving quantities into series; but we must first show nun~l how the theorem itself may be investigated. Let a-f a? be any binomial quantity which is to be rais- nu or to the following : m ed to a power denoted by —, where m and n are any numbers either positive or negative. 11 u“ —un (A-f2 By-f scy-f 4 D^-fS Ey4-!-, &c.); so that, putting for um and un their values (l-fy)n and Because a+x—a fl-f-V if we put - rry, then (a-f #)»» \ ' aj ‘■a ™ we have — an x(l+y)n ; therefore, instead of a-frr, we may consider 1-fy, which is somewhat more simple in its form. By considering some integer powers of 1 + #, as (1-fa?) zrl-f x, (1-fa?)2 = l-f 2a?-f a?2, (1-f a?)3r=l-f 3a;4"3,c2+ ^ (1-f a:)4 =l-f 4a;-f 6^2-f ^,a;3 + a'4> &c. it may be inferred that all powers of 1 -fa: have this form, 1-f Aa:-f Ba:2-f Ca^-f Da^-f Ea^-f, &c. where the co-efficients A, B, C, D, E, &c. are numbers which are altogether independent of any particular value of x. It also appears that the series cannot contain any negative power of x; for if any of its terms had this form, ^ (1-f y)n=(l-f 7/)(A+2B^+3C^2+4Dy3+5Ey4+,&c) _ f A +2 B7/ +3 Ct/2 -f 4 D^-f 5 E^-f, &c. — ( -f Ay -f 2 By2 -f 3 Cy3 -f 4 Dy4 -f, &c.

XVIII.—Of the Reversion of Series. 163. The method of indeterminate co-efficients, which we have already employed when treating of infinite se¬ ries, may also be applied to what is called the reverting of series; that is, having any quantity expressed by an infinite series composed of the powers of another quan¬ tity, to express, on the contrary, the latter quantity by means of an infinite series composed of the powers of the former. Let y—n-^-ax + bxP^-cxP-^dxt-^, &c. Then, to revert the series, we must find the value of x in terms of y. For this purpose, we transpose n, and put z—y — n ; then zz=ax-\-bx?-\-cxi-\-dxA-\-, &c.

If y be nearly = 2, the series will converge too slowly to be of use, and if it exceed 2, the series will di¬ verge, and therefore cannot be directly applied to the finding of its logarithm.

When a number is composite, its logarithm will most easily be found, by adding together the logarithms of its factors ; but if it be a prime number, its logarithm may be derived from that of some convenient composite number, either greater or less, and an infinite series.

They have been called Hyperbolic Logarithms because they serve to express the area of an hyperbola • but this may be done by logarithms of any system.

But this last series is the same as we have denoted by A; hence it follows, that the modulus of any system is the reciprocal of the Napierian logarithm of the radical num¬ ber of that system. Thus it appears that the logarithms of numbers, according to any proposed system, may be readily found from the Napierian logarithm of the same numbers, and the Napierian logarithm of the radical num¬ ber of that system. 174. Let L denote the Nap. tog. of any number, ami l, P the logarithms of the same number according to two other systems whose modidi are m and m'; then l=mL, P—mlL; l P therefore, — = —and mvwl w l \P. m m That is, the logarithms of the same number, according to different systems, are directly proportional to the moduli of these systems, and therefore have a given ratio to one another. 175. We shall now apply the series here investigated to the calculation of Napier's logarithm of 10, the reci¬ procal of which is the modulus of the common system of logarithms ; and also to the calculation of the common logarithm of 2. The Nap. tog. of 10 may be obtained by substituting 10 for y in the formula %—!) . 2(y—i\ , 2/>-a\ ■sl5+U +51.

By substituting 2 in the formula, we have 1 . 1 Nap. log. 2=20 33+5.35+7.37+ &c. Iog- n+x(2^+! + +, &C-) This series gives the logarithm of «-j-z by means of the logarithm of n, and converges very fast when n is con¬ siderable. 172. It appears, from the series which have been found for tog. y, that the logarithm of a number is always the product of two quantities: one of these is variable, and depends upon the number itself; but the other, viz. —, is constant, and depends entirely on the radical number of the system. This quantity has been called by writers on logarithms the modulus of the system. 173. The most simple system, in respect to facility of computation, is that in which -r-=l or A=l. The toga- rithms of this svstem are the same as those first invented This series converges very fast, so that by reducing its terms to decimal fractions, and taking the sum of the first seven terms, we find the Nap. tog. of 2 to be -6931472. The Nap. tog. of 5 may be found in the same manner, but more easily from the formula given in sect. 171- l °r the tog. of 2 being given, that of 4=22 is also given (sect. 166) ; therefore, substituting tog. 4 = 2 log. 2 for log. and 1 for z, in the series Nap. tog.

We have seen, sect. 169, that to determine the loga¬ rithm of a given number, is the same problem as to deter¬ mine the value of x in an equation of this form, ax=i, where the unknown quantity is an exponent. But in or¬ der to resolve such an equation, it is not necessary to have recourse to series; for a table of logarithms being once supposed, constructed, the value of x may be determined 'thus: It appears, from sect. 166, that ax log.a=log. 6; _ ^ by n ought therefore to destroy each other, and then the equation is reduced to rt=y=i+^+ a-2A2 . a?A3 1 ' 1-2 and since we have found rj3 (r—l)2 1-2 3 + l aM4 ■2-3-4 + , &c.

Algebra, may suppose that the interest, which is always propor- ' tional to the sum lent, or principal, is also proportional to the time during which the principal is employed; and on this hypothesis, the money is said to be improved at sim¬ ple interest. Or we may suppose that the interest which ought to be paid to the lender at successive stated pe¬ riods is added to the principal, instead of being actually- paid, and thus their amount converted into a new princi¬ pal. When money is lent according to this second hypo¬ thesis, it is said to be improved at compound interest. 180. In calculations relating to interest, the things to^ be considered are the principal, or sum lent; the rate of interest, or sum paid for the use of L.100 for one year; the time during which the principal is lent; and the amount, or sum of the principal and interest, at the end of that time. Let p denote the principal, L.l being the unit; r the interest of L.l for one year, at the given rate ; t the time, one year being the unit; a the amount. log. jprzlog. a — £ X log. R. log.

Because the interest of L.l for one year is r, the interest of L.l for £ years must be rt, and the interest of p pounds for the same time prt; hence we have this formula, from which we find pX-prt—a, In treating of compound interest, we have supposed the interest to be joined to the principal at the end of the year. But we might have supposed it to be added at the end of every half-year, or every quarter, or even every instant; and suitable rules might have been found for performing calculations, according to each hypothesis. As such suppositions are, however, never made in actual business, we shall not at present say any thing more of them. p- r— ~P t= ~P \+rt pt pr As the manner of applying these formulae to questions relating to simple interest is sufficiently obvious, we pro¬ ceed to consider compound interest. Compound Interest. 182. In addition to the symbols already assumed, let R=l+7’ = amount of L.l in one year; then, from the nature of compound interest, It is also the principal at the beginning of the second year. Now, interest being al¬ ways proportional to the principal, we have 1 : r :: R : rR=: the interest of R for a year, and R + rR = (l+r)R = R2= amount of R in a year; therefore It2 is the amount of L.l in two years, which sum being assumed as a new principal, we find, as before, its interest for a year to be rlt2, and its amount R2-{-rR2 — (1 -J-t^R^R3 ; so that It3 is the amount of L.l in three years. Proceeding in this manner, we find, in general, that the amount of L.l in £ years is R', and of p pounds, pR‘; hence we have this formula, y?R'=a; which, from the nature of logarithms, may also be express¬ ed thus: log. p-J-fXlog. R=log. a. We have also P- R‘ R ='fb Annuities. 183. An annuity is a payment made annually for a terra of years; and the chief problem relating to it is to deter¬ mine its present worth, that is, the sum a person ought to pay immediately to another, upon condition of receiving from the latter a certain sum annually for a given time. In resolving this problem, it is supposed that the buyer improves his annuity from the time he receives it, and the seller the purchase-money, in a certain manner, during the continuance of the annuity, so that at the end of the time the amount of each may be the same. There may be various suppositions as to the way in which t re annuity and its purchase-money may be improved; but the only one commonly applied to practice is the highest improvement possible of both, viz. by compound inteiest. As the taking of compound interest is, however, prohibited by law, the realizing of this supposed improvement re¬ quires punctual payment of interest, and therefore 16 interest in such calculations is usually made low. 184. Let A denote the annuity, P the present worth, or purchase-money, t the time of its continuance; let r and R denote as before. • . . The seller, by improving the price P at compoun terest during the time t, has PR'. . The purchaser is supposed to receive the first annuj A at the end of one year, which, being improved tor t years, amounts to Alt'-1. He receives the secon y ‘ annuity at the end of the second year, which, bein» proved for t—2 years, amounts to Alt'j2.

To find the present value of an annuity in rever¬ sion, that is, an annuity which is to commence at the end of n years, and continue during t years; first find its value stitution, for n-\-t years, and then for n years, and subtract the 314159 1 latter from the former; we thus obtain the following for- Tnnnnn=3 + ;? . 1 mula: 1000()0 7+ 15 4.1 p— —(1 Ly rlin\ R'/ 186.

Every quantity which admits of being expressed ... d by a common fraction may also be expressed in the form ^ evidently be reduced to a common fraction by of what is called a continued fraction.

And by taking the first four terms, we have For if x be the root sought, we have a;=a4--,w=64.i ; ° ‘ y * '=3+7+- 1 , + 15+i 355 : 113’ which is the proportion assigned by Metius, and is more exact than either of the preceding. The results are al¬ ternately greater and less than the truth. 190. Among continued fractions, those have been par¬ ticularly distinguished in which the denominators, after a certain number of changes, are continually repeated in the same order. Such, for example, is the fraction tf—b' + y,, &c. where a, B, W, V", &c. denote the whole numbers, which are next less than the true values of x, y, tf, y", &c. If, therefore, in the value of a: we substitute f°r y> ^ becomes x—a-\- ^ ^ + .1. y Again, if in this second value of a: we substitute i+!+a i 3+i ] 2+3+) for y, it becomes &c. x—a-{- b+- The value of this fraction, though continued ad infini¬ tum, may be easily found ; for leaving out the first term, which is an integer, let us suppose 1 V+ The next value of x is in like manner found to be *~2+i+i J 3 + 2+13 + ,&c. x=za-\-T-~l i+r. Then, since after the second, all the terms return in the and so on continually, same order, it follows that their amount is also = x. Thus we have Sect.

Though the denominators 2 ' 4 • a did not return in the same order till after a greater inter¬ val, the value of the fraction would still be expressed by the root of a quadratic equation. And conversely^, the roots of all quadratic equations may be expressed by pe¬ riodical continued fractions, and may often by that means be very readily approximated in numbers, without the trouble of extracting the square root. 191. The reduction of a decimal into the form of a con¬ tinued fraction sometimes renders the law of its continua¬ tion evident. Thus we know that a/2=T4121356... ; but from the bare inspection of this decimal we discover no rule for its further continuation. If, however, it be re¬ duced into a continued fraction, it becomes 192. When the conditions of a question are such that the number of equations exceeds the number of unknown quantities, that question will admit of innumerable solu¬ tions, and is therefore said to be indeterminate. Thus, if it be required to find two numbers subject to no other li¬ mitation than that their sum be 10, we have two unknown quantities x and y, and only one equation, viz. which may evidently be satisfied by innumerable different values of x and y, if fractional solutions be admitted. It is, however, usual, in such questions as this, to restrict values of the numbers sought to positive integers, and therefore, in this case, we can have only these nine solu¬ tions, x — 1, 2, 3, 4, 5, 6, 7, 8, 9; y = 9, 8, 7, 6, 5, 4, 3, 2,1; which indeed may be reduced to five; for the first four be¬ come the same as the last four, by simply changing x in y, and the contrary. 193. Indeterminate problems are of different orders, ac¬ cording to the dimensions of the equation which is o - tained after all the unknown quantities but two have been exterminated by means of the given equations. 1l0iC of the first order lead always to equations of this form, =i+!+i i 2+2+, &c. ax-\-by=c, x—y +w’anc* y— 20# — 7 11 = v 9v 11 hence 9# —7 11 must be a whole number.

Put — then t—ks-\-r and s-=z2r~l. Having now no longer any fractions, we return to the values of x and y by the following series of equations ; s=2r + 7, t— 4s -j-r— 9r + 28, v— ^+5 = ll7’d-35, y— v-j-^ — 20r-j-63— number of oxen, x— y4-^ = 31r-f 98= number of horses. The least positive values of x and y will evidently be obtained by making r— — 3, and innumerable other values may be had by putting r— —2, r— — 1, r—0, r-zz. + 1, &c. Thus we have x=5, 36, 67, 98, 129, 160, 191, 222, &c. y=3, 23, 43, 63, 83, 103, 123, 143, &c. each series forming an arithmetical progression, the com¬ mon difference in the first being 31, and in the second 20. 195. If we consider the manner in which the numbers x, y, in this example, are determined from the succeed¬ ing quantities v, t, etc. we shall immediately perceive that the co-efficients of those quantities are the same as the successive quotients which arise in the arithmetical ope¬ ration for finding the greatest common measure of 20 and 31, the co-efficients of the given equation 20a;=:31^-f-7. The operation performed at length will stand thus : 20)31(1 20 11)20(1 11 9)11(1 9 2)9(4 8 1)2(2 2 0 Hence we may form a series of numeral equations which, when compared with the series of literal equations expressing the relations between x, y, v, &c. as put down in the following table, will render the method of deter¬ mining the latter from the former sufficiently obvious. 31 = 1x20-{-11 20=1x11+ 9 ll = lX 9+ 2 9=4x 2+ 1 2=2x 2+ 0 x=\xy+v, yzz\xv+t, v~ 1 x * + s, <=4 x s +7’, s=2x/,+7. And as every question of this kind may be analyzed in the same manner, we may hence form the following gene¬ ral rule for resolving indeterminate problems of the first order. of equations from which another series maybe derived nc ai in the following table : a—Ab-\-c, hence we find x— Ay+v, i=Bc + c? y=¥>v+t, c= CrZ + e v—Ct +s, d~T)e-\-f <=Ds-{-7', e—W+9 s^Er+gr, f— F<7 + 0 r= Yqztin. And in the last equation of the second series any number whatever may be put for q. It is also to be observed that the given number n is to have the sign + prefixed to it, if the number of equations be odd, but — if that number be even. Having formed the second series of equations, the values of x and y may be thence found as in the foregoing examples. We proceed to show the ap¬ plication of the rule. ira. ^ V Ex. 5. Required a number which, being divided by II, leaves the remainder 3, but being divided by 19, leaves the remainder 5. Let N be the number, and x, y, the quotients which arise from the respective divisions ; then we have Nnlkc + 3, also N=19?/-{-5; hence lla? + 3=19^+5, and 1 la: = 19^ + 2, an equation which furnishes the following ta¬ ble : 19=1x11 + 8 H = lX 8 + 3 8=2 x 3 + 2 3=1 X 2+1 2=2 x 1 + 0 Here r may be assumed of any we have X— 7/ + t?, V— v + t, vz=2t +5, t= s+r, s=2r+ 2. value whatever. Hence s=2r +2, t— 5 + /• = 3r + 2, v—2t + 5= 87”+ 6, yzz v + £=11t’+ 8, xzz y+«= 197’+14; and the number required, N=2097«+157, where it is evi¬ dent that the least number which can express N is 157. Ex. 6. j3x-\- 5^+ 7z=560 1 To determine a:,y, 2, Given |9a: + 25y + 49z=2920| in whole numbers. From 7 times the first equation subtract the second; thus we have 12a:+10y=1000, or 6a? + 5y=500; and from this last equation, by proceeding as in the foregoing ex¬ ample, we find a?=500 — 5v, y— 6v — 500. Let these values of x and y be substituted in either of the original equations ; in the first, for example, as being the most simple, and we find 7z+15tj=1560. This last equation being resolved in the same manner, we find i’=1560 — 7/, z=15£ —3120, y=8860 — 42£, yzz35t —7300; and hence it appears that the only values which t can have, so as to give whole positive numbers for x, y, z, are 209 and 210: thus we have 196. Let bx~ ay + n be the proposed equation, in which a, b, n, are given integers, and x, y, numbers to be found. Let a be the greatest of the two numbers a, b, and let A denote the greatest multiple of b which is con¬ tained in a, and c the remainder; also let B denote the greatest multiple of c contained in b, and d the remain¬ der ; and C the greatest multiple of d contained in c, and e the remainder ; and so on, till one of the remainders be found equal to 0. The numbers A, B, C, afford a series x—15 t/=82 z= 15, or a;=50 y=40 z=30. 197. If an equation were proposed involving three un¬ known quantities, as ax^-by-\-cz—d, by transposition we have ax-\-by—d—cz, and, putting d— cz—d, ax\by^- From this last equation we may find values of x and y of this form, x—mr-^-nd, y—nir^rid, or x—mr-\-n(d — ex'), yzzmlr—cz); where z and r may taken at pleasure, except in so far w/as the values of y, z, may be required to be all positive; for from such restriction the values of 2 and r may be con¬ fined within certain limits to be determined from the given equation. . 198. We proceed to indeterminate problems of the second degree. These produce equations of the three following forms: I v— —■> II. III. 7/:= Va + kr+cx2. b + cx u c-\-dx u In all these equations a, b, c, denote given numbers. In the first two, x is to be determined so that y may be an integer; and in the third, x is to be determined so that y may be a rational quantity. In the equation y— evident, b-\-cx must be a divisor of a; let d be one of its divisors, then b-\-cx=.d, and : hence, to find x we must search among the divisors of a for one such, that if b be subtracted from it, the remainder may be divisible by c, and the quotient will be such a value of x as is required. CL I hjC . • • When ?/— -'if ^ be a divisor of b, x will be taken ^ c-\-dx out of the numerator if we divide it by c-\-dx, and this form is then reduced to the preceding. But if d is not a divisor of b, multiply both sides by d, then dy— da-\-dbx ALGEBRA. Here m, as before, may be taken at pleasure. Case 3. When neither a nor c is a square number, yet if the expression a + bx + cx? can be resolved into two simple factors, as/+#x and h + kx, the irrationality may be taken away as follows. or dy—b-^ ad—be c-\-dx and so x is found by making c-\-dx c-\-dx' equal to a divisor of ad — be.

We are next to consider the formula y — Va-\-bx-{-cxP, where x is to be found, so that y may be a rational quantity; but as the condition of having x and y also integers would add greatly to the difficulty of the pro¬ blem, and produce researches of a very intricate nature, we must be satisfied for the most part with fractional values. The possibility of rendering the proposed formula a square depends altogether upon the co-efficients a, b, c ; and there are four cases of the problem, the solution of each of which is connected with some peculiarity in its nature. Case 1. Let a be a square number ; then, putting y2 for ff) we have y=V(f + bx -j- cx2. Suppose Vg2 -j- bx -f- ex2 ~9 + mx; theng-^.bx-\-c:tr~g2 + 2gmx-f-m2x?,or bx-j-cx2 that is, b cx—2gm -{- m2x ; hence __ 2gm — b x~ c — m2 , y—\/'g2-[-bx-\-cx2 — eg — bm gm2 Here m may be any rational quantity, either whole or fractional. Case 2, Let c be a square number —g2; then, putting a-¥bx-\-g2a?-=zm+gx we find a +Jx+y2x2=»i2-j-2wyx +/X2, or a+bx—m2-\-2mgx; hence we find m* — a bZZiX-g' V- J bm — gw? — ag 2mg Assume +« + bx + cx2— +(/+ gx)(h + kx)—w(/+yx), tli en ( jf+ yx) (4 + Ax)—m2( f-\- yx)2, or A + /ix=m2( /+ gx); hence we find ^ y= and in these formulae m may be taken at pleasure. Case 4. The expression a + bx + cx2 may be transform¬ ed into a square as often as it can be resolved into two parts, one of which is a complete square, and the other a product of two simple factors ; for then / it has this form, where/>, q, and r are quantities which con¬ tain no power of x higher than the first. Let us assume Vp2 4- qr—p -f wiq; thus we have jt>2 -f qr—p2 4- 2mpq 4- m2q2 and rz=.2mp-\-m2q, and as this equation involves only the first power of x, we may by proper reduction obtain from it rational values of x and y, as in the three foregoing cases. 200. If we can by trials discover any one value of x which renders the expression Va-^-bx-J^cx2 rational, we may immediately reduce the quantity under the radical sign to the above-mentioned form, and thence find a general expression from which as many more values of x may be determined as we please. Thus, let us suppose that is a value of x which satisfies the condition requir¬ ed, and that q is the corresponding value of y ; then y2—a -j- ^ + 0, e—— 1, and substituting these values in the formulae of sect. 199, also —n for +»*, we find 2an a(r?—1) x~W+Vy- w24-l ; required are 4«%2 hence the numbers If >* + 1) where r 024-l)2 «2 + l, where n is any number whatever, the square numbers x2 and y2 will both be integers, viz. x2 = 4w2 and y~ = (n'2 — l)2. Let us suppose n—2, then a — n2 \ — 5, and «2 = 25, hence x2 — 4»2 =r 16, y—{n2 — l)2 = 9. Thus it appears that the square num¬ ber 25 may be resolved into two other square numbers, 9 and 16. 480 ALGEBRA. Algebra. ^ Ex. 2. It is required to find two square numbers whose difference shall be equal to a given square num¬ ber b*. This question may be resolved in the same manner as the last. Or, without referring to any former in¬ vestigation, let (tf-f-w)2 and #2 be the numbers sought, then (a:-J-«)2 — x*2 — b‘2 ; that is, 2nx -f- w2 = b<2, hence b2 — n2 , J2 and x-\-n-=i—1— .t—- 2n sought are 2n So that the numbers (b2+n2)2 (b2—n)2 4«2 ’ 4w2 ’ where n may be any number whatever.

Sect. XXIII.—Of the Resolution of Geometrical Problems. 201. When a geometrical problem is to be resolved by algebra, the figure which is to be the subject of in¬ vestigation must be drawn, so as to exhibit as well the known quantities connected with the problem, as the unknown quantities which are to be found. The condi¬ tions of the problem are next to be attentively con¬ sidered, and such lines drawn, or produced, as may be judged necessary to its resolution. This done, the known quantities are to be denoted by symbols in the usual manner, and also such unknown quantities as can most easily be determined; which may be either those directly required, or others from which they can be readily found. We must next proceed to deduce from the known geo¬ metrical properties of the figure a series of equations, expi’essing the relations between the known and un¬ known quantities; these equations must be independent of each other, and as many in number as there are un¬ known quantities. Having obtained a suitable number of equations, the unknown quantities are to be determined in the same manner as in the resolution of numerical pro¬ blems. No general rule can be given for drawing the lines, and selecting the quantities most proper to be represent¬ ed by symbols, so as to bring out the simplest conclu¬ sion ; because different problems require different me¬ thods of solution. The best way to gain experience in this matter, is to try the solution of the same problem in different ways, and then apply that which succeeds best A] to other cases of the same kind, when they afterwards^ occur. The following particular directions, however, may be of some use. ’ ^ 1. In preparing the figure by drawing lines, let them be either parallel or perpendicular to other lines in the figure, so as to form similar triangles. And if an angle be given, it will be proper to let the perpendicular be op¬ posite to that angle, and to fall from one end of a given line, if possible. 2. In selecting the quantities for which symbols are to be substituted, those are to be chosen, whether re¬ quired or not, which lie nearest the known or given parts of the figure, and by means of which the next adjacent parts may be expressed by addition and subtraction only, without the intervention of surds. 3. When two lines, or quantities, are alike related to other parts of the figure, or problem, the best way is to substitute for neither of them separately, but to substi¬ tute for their sum, or difference, or rectangle, or the sum of their alternate quotients, or some line or lines in the figure, to which they have both the same relation. 4. WTien the area or the perimeter of a figure is given, or such like parts of it as have only a remote relation to the parts required, it is sometimes of use to assume another figure similar to the proposed one, having one side equal to unity, or some other known quantity. For thence the other parts of the figure may be found by the known proportions of like sides or parts, and so an equa¬ tion will be obtained. 202. We shall now give the algebraical solutions of some geometrical problems. ira, V Prob. 1. In a right-angled triangle, having given the base, and the sum of the hypothenuse and perpendicular, to find both these sides. Let ABC (Plate XVIII. fig. 1) represent the proposed triangle, right-angled at B. Let AB, the given base, be denoted by b, and AC + BC, the sum of the hypothenuse and perpendicular, by s; then if x be put for BC the perpendicular, the hypothenuse AC will be —s — x. But from the nature of a right-angled triangle, AC2 = AB2 + BC2, that is, b?-{-x?= (s — x^zza? — 2sx-]-x2. O 70 Hence b2 — s2 — 2sx, and x — —-— = BC. is AT & V2 S2 A-b2 * r' 'TV. Also s — x — s = —A;— — AC. Thus the 2s 2s perpendicular and hypothenuse are expressed by means of the known quantities b and s, as required. If a solution in numbers be required, we may suppose AB=6=3, and AC + CB=5=9; then BC = = 4, and AC = - 2s 2s = 5. Prob. 2. In a right-angled triangle, having given the hypothenuse, also the sum of the base and perpendicular, it is required to determine these two sides. Let ABC (fig. 1) represent the proposed triangle, right-angled at B. Put «=:AC the given hypothenuse, and s=AB + BC the given sum of the sides; then, if a: be put for AB the base, s — x will denote BC the perpen¬ dicular. Now, from the nature of right-atigled triangles, AC* = AB2 + BC2 ; therefore x2 (s — x)2 = a‘2, or x22r s<2 — 2sx-\-x2zza2; hence we have this quadratic equa- Alg.^tion, x2 — ALGEBRA. which being resolved, by com- 481 pleting the square, we find x = sz±zV2a‘^ —s2 = AB, and szizV2a2 — s2 s — z=- either of the two quantities s-\-V2a2—s2 s — V2a2—s2 2 ’ 2 ’ xy—af, From the first equation we find y—^, and from the px second, y — ^X, therefore ^-r o o —— ; hence x? — x bx= —. a2b and from this quadratic equation, by complet¬ ing the square, &c. we find 2 * 1 '2 v T~7’andy Hence it appears, that if lit - „ -2 v 4 x (fib ~F pa* 'T blem possible, the given space a2 must not be greater than Algebra. pb that is, than half the area of the given triangle. = BC. Thus it appears, that may be taken for AB; but whichever of the two be taken, the remaining one is necessarily equal to BC. Prob. 3. It is required to inscribe a square in a given triangle. Let ABC (fig. 2) be the given triangle, and EFHG the inscribed square. Draw the perpendicular AD, cutting EF, the side of the square, in K ; then, because the tri¬ angle is given, the perpendicular AD may be considered as given. Let BC=6, KD=.p, and considering AK as the unknown quantity (because from it the square may be readily determined), let AKrzx; thenKDrrEF=jo—x. The triangles ABC, AEF, are similar; therefore AD : BC : : AK : EF, that is, jo : 6 : : a?: jo — x. Hence, by taking the product of the extremes and means, p2 —pxzzbx, and ^ z= AK. If the side of the square be required, it may be immediately found by subtract¬ ing AK from AD the perpendicular. Thus we have ^ence appears that we may either take AK, a third proportional to AD + BC and AD, or take DK, a fourth proportional to AD + BC, AD and BC; and the point K being found, the manner of de¬ scribing the square is sufficiently obvious. Prob. 4*. Having given the area of a rectangle inscrib¬ ed in a given triangle ; it is required to determine the sides of the rectangle. Let ABC (fig. 3) be the given triangle, and EDGF the rectangle whose sides are required. Draw the perpendi¬ cular Cl, cutting DG in H. Put AB=6, CI=j9, DG=EF =x, DE=HI=3/; ^en CH=:/> — y. Let a2 denote the given area. The triangles CDG, CAB, are similar ; hence CH : DG :: Cl: AB, ox p — y: x:: p i b. So that to determine x and y, we have these two equa¬ tions, „2 ip — by—px. a? x Prob. 5. In a triangle, there are given the base, the vertical angle, and the sum of the sides about that angle ; to determine each of these sides. Let us suppose that ABC (fig. 4) is the triangle, of which there is given the base AC, the vertical angle ABC, and the sum of the sides AB, BC. Put AC = a, AB-|-BC=&, cosine of ^lABC—c; and let AB, BC, the sides required, be denoted by x and y. Let CD be drawn from either of the angles at the base perpendicular to the opposite side AB; then, rad. : cos. B :: CB : BD ; therefore BDzrcos. B X CBzzcy. Now, from the principles of geometry, AC2rzAB3 -f- BC2 — 2AB X BD. Hence, and from the question, we have these two equations, xJ[-y=b, x3 — 2cxy+y2—a2. From the square of the first of these equations, viz. x2+2xy+3/2=^25 let the second be subtracted; thus we . ^2 have 2(1 Jrc)xy—lfi — a2, and 2xy— ^ |—. Again, from I -\-c the square of the first equation let the double of this last 2(^2 a2\ equation, viz. 4xy— ■ |—be subtracted, and the re- 1 + c suit is xfi — 2xy-\-y2z=. + < 1 2a2 — (1—c)lfi 1+c so that by taking the square root of this last equation, we obtain —y-*J 1+c c)b2 Thus we have found the difference between the sides, now their sum is given —b; hence, by adding ^ the difference to ^ the sum, we find j ,c and subtracting \ the difference from ^ the sum, V 2 1 /2«2 — 2 V J {\—c)V —J— O & be less than —, that is, if 4 If the angle at B be a right angle, this problem becomes the same as prob. 2. Prob. 6. To draw a straight line through a given point P (fig. 5), so as to form with AB, AC, two straight lines given in position, a triangle DAE equal to a given space. Draw PF parallel to AC, one of the lines; and DH, PG, perpendicular to AB, the other line: then PF will be given in position; and AF, PG, will be given in mag¬ nitude. Put the known magnitudes AF=a, PG=fi, and AE, a side of the triangle which is to be determined, —x. Also, let the given space to which the triangle ADE is to be equal, be c2. By similar triangles, FE : PG ;: AE : DH ; that is, x — a\b'.\x\ DH; hence DH = —^; and triangle ADE= — x ■ bxfi •2d a~ be less than there are two different rectangles, Therefore ^=c2, and bxP= 2c2x — 2a0S!te SideS 0f AE if the3' have c0’!

Hence it appears that in any par- two (sect. 204). t Elg lt me Can never exceed ticular equation we may determine as many points M as fWvpa'wwl ^ . we please; and a line which passes through all these ^ i„.. c i0nSv ^re 0 three ^mensions form points is called the loctis of the equation. The line AP which expresses any value of x, is called an absciss; and PM, which expresses the corresponding value ofy, is called an ordinate. Any two corresponding values of x and y are also called co-ordinates. 205. When the equation that arises by substituting for any particular value AP has all its roots positive, the points M, M', &c. will lie all on one side of AE ; but if any of them be negative, these must be set off on the other side of AE towards m. If x be supposed to become negative, then the line Ap, which represents it, is to be taken in a direction the opposite to that which represents the positive values ofx; the points M, rn, are to be taken as before, and the locus is only complete when it passes through all the points M, m, so as to exhibit a value of y corresponding to every possible value of x. J If in any case one of the values of y vanish, then the point M coincides with P, and the locus meets AE in that point. If one of the values of y becomes infinite, then it shows that the curve has an infinite arc, and in that case the line PM becomes an asymptote to the curve, or touches it at an infinite distance, if AP itself is finite. If, when x is supposed infinitely great, a value of y ’ anish, then the curve approaches to AE as an asymptote. If any values of y become impossible, then so many points M vanish. the third order of lines and the their intersections with a straight line can never exceed three; and after the same manner curves of the higher orders are denominated. s ier Some curves if they were completely described, would cut a straight line in an infinite number of points; but * - J iese J,e!ong to none of the orders we have mentioned, for * any particular value AP has all its roots positive, the the relation between their ordinates and abscisses rJnnf- nnints M. M'. &c. will he all nn on. c,Vlo nf a 'P . t,..* be expressed by a finite equation, involving only ordinates and abscisses with determinate quantities. Curves of this kind are called mechanical or transcendental. 208. As the roots of an equation become impossible al¬ ways in pairs, so the intersections of a curve and its or- tITp vanish in pairs, if any of them vanish. J U cut the curve 111 tIle points M and m and, by moving parallel to itself, come to touch it in the point N, then the two points of intersection M and m ao to form one point of contact N. If PM still move on, parallel to itself, the points of intersection will, beyond N become imaginary, as the two roots of an equation first become equal, and then imaginary. The curves of the 3d, 5th, 7th orders, and all whose di¬ mensions are odd numbers, have always one real root at least; and consequently for every value ofx the equation by which y is determined must have at least one real root; so that as x or AP may be increased in infinitum on both sides, it follows that M must go off on both sides without limit. 206. From these observations, and the theory of equa¬ tions, it appears that when an equation is proposed in¬ volving two indeterminate quantities x and y, there may be as many intersections of the curve which is the locus of the equation, and of the line PM, as there are dimensions ot y in the equation; and as many intersections of the curve and the line AE as there are dimensions of x in the equation. ~0g A curve line is called geometrical, or algebraic when the equation which expresses the relation between ■r and y (any absciss and its corresponding ordinate), con¬ sists of a finite number of terms, and contains, besides these quantities, only known quantities. Algebraic curves are 1V1 . ln^° orders, according to the dimensions of the equations which express the relations between their ab¬ scisses and ordinates, or according to the number of points in which they can intersect a straight line. < tiaight lines themselves constitute the first order of "ies; and when the equation expressing the relation be- wccn x and y is only of one dimension, the points M, &c. is )e all found in a straight line which contains with AE given angle. Suppose, for example, that the given equa- n is ay bx cd— 0, and that its locus is required. Since yJ^±^Li it follows that APM (fig. 11) being such H*' ^n^e’ if AN be drawn making the angle NAP a cosine is to its sine as a to b, and drawing parallel t0 the ordinates PM, and equal to —, if DF In curves whose dimensions are even numbers, as the roots of their equations may become all impossible, it fol¬ lows that the figure of the curve may be like a circle, or oval, that is, limited within certain bounds, beyond which it cannot extend. 209. When two roots of the equation by which y is de¬ termined become equal, either the ordinate PM touches the curve, two points of intersection in that case going into a point of contact; or the point M is apunctum du¬ plex in the curve, two of its arcs intersecting each other there; or some oval that belongs to that kind of curve be¬ coming infinitely little in M, it vanishes into what is called a punctum conjugatum. If, in the equation, y be supposed =0, then the roots of the equation by which x is determined will give the dis¬ tances of the points where the curve meets AE from A; and if two of those roots be found equal, then either the curve touches the line AE, or AE passes through a punctum duplex in the curve. When y is supposed = 0, if one of the values of x vanish, the curve in that case passes through A ; if two vanish, then either AE touches the curve in A, or A is a punctum duplex. As a punctum duplex is determined from the equality of two roots, so is a punctum triplex from the equality of three roots. 210. To illustrate these observations, we shall take a few examples. Ex. 1. It is required to describe the line that is the locus of this equation, y^—ax-^ab, or y- — ax — ab—0, where a and b denote given quantities. Since tfi 484 ALGEBRA. Algebra. _ ±*/ax + ab; if AP = z (fig. 13) be assumed of a / known value, and PM, Pm, set off on each side equal to axab, the points M, m, will belong to the locus required; and for every positive value of AP there may thus be found a point of the locus on each side. The greater that AP or x is taken, the greater does Vax-\-ab become, and consequently PM and Pm the greater; and if AP be supposed infinitely great, PM and Pm will also become infinitely great; therefore the locus has two infinite arcs, that go off to an infinite distance from AE and from AD. If x be supposed to vanish, then y— —1— ^cb, so that y does not vanish in that case, but passes through D and d, taking AD and Ad each — V ab. infinite; so that if AK be taken =a+c, the ordinate KF will be an asymptote to the curve. If x be taken greater than a + c, or AP greater than AK, then both c — x and a+c — x become negative, and consequently y bY. becomes a positive A1g< i. If P be supposed to move on the other side of A, then x becomes negative, and y = r±= Vab — ax, so that y will have two values as before, while x is less than b; but if AB = b, and the point P be supposed to come to B, then ab—ax, and y — *, that is, NM X GN=GC X BC, which is the property of the com¬ mon hyperbola.

If x be supposed greater than a, or AP greater than AB, then a—x being negative, the fraction x will become negative, and its square root impos- a—* sible ; so that no part of the locus can lie beyond B. If x be supposed negative, or P taken on the other side of Here it is evident (fig. 14) that the ordinate PM can meet the curve in one point only, there being but one value of y corresponding to each value of x.

The whole curve, except this point, lies between and BK. These remarks are demonstrated after the same manner as in the first case. 211. If an equation have this form, y—axn -j- -j- cxn~2 , &c. and n is an even number, then will the lodus of the equation have two infinite arcs lying on the same side of AE (fig. 18); for if a; become infinite, whether positive or negative, a;n will be positive and axn have the same sign in either case; and as axn becomes infinitely greater than the other terms bxn~l, &c. it follows that the infinite values of y will have the same sign in these cases, and consequently the two infinite arcs of the curve will lie on the same side of AE. But if n be an odd number, then when x is negative, xn will be negative, and will have the contrary sign to what it has when x is positive ; and therefore the two in¬ finite arcs will in this case lie on different sides of AE, as in fig. 19, and tend towards parts directly opposite. 212. If an equation have this form, yxnzzan+l, and n be • • • ^ an odd number, then when x is positive, yzz ; but 485 when ads negative, so that this curve must all lie in the vertically opposite angles KAE, FAe (fig. 20), as the common hyperbola, FK, Ec being asymptotes. But if n be an even number, then y is always positive, whether x be positive or negative, because xn in this case is always positive; and therefore the curve must all lie in the two adjacent angles KAE and KAe (fig. 21), and have AK and AE for its asymptotes. 213. If an equation be such as can be reduced into two other equations of lower dimensions, without affecting y or x with any radical sign, then the locus will consist of the two loci of those inferior equations. Thus, the locus of the equation y2 — 2xy J^by+x2 — which may be resolved into these two, x — y=0, y — ar-f-&=0, is found to be two straight lines cutting the absciss AE (fig. 22) in angles of 45° in the points A, B, whose dis¬ tance AB=b. In like manner some cubic equations can be resolved into three simple equations, and then the locm is three straight lines; or may be resolved into a quadra¬ tic and simple equation, and then the locus is a straight line and a conic section. In general, curves of the supe¬ rior orders include all the curves of the inferior orders, and what is demonstrated generally of any one order is also true of the inferior orders. Thus, for example, any gene¬ ral property of the conic sections holds true of two straight lines as well as a conic section, particularly, that the rect¬ angles of the segments of parallels bounded by them will always be to one another in a given ratio. 214. From the analogy which subsists between algebraic equations and geometrical curves, it is easy to see that the properties of the former must suggest corresponding properties of the latter. Hence the principles of algebra admit of the most extensive application to the theory of curve lines. It may be demonstrated, for example, that the locus of every equation of the second order is a conic section; and, on the contrary, the various properties of me diameters, ordinates, tangents, &c. of the conic sec¬ tions may be readily deduced from the theory of equa- Sect. XXV. Arithmetic of Sines. th ^e- ca^cu^us sines is one of the mathematical cones which have been produced by the application of * gebra to geometry. It treats of the relations which Smes’ cosbies, tangents, Sec. of angles have one to another. 216. The geometrical principles of this theory were Algebra, known to the ancients. They may be deduced from thev^v^> beautiful property of a quadrilateral inscribed in a circle namely, that the rectangle contained by its diagonals is equal to the sum of the rectangles contained by its oppo¬ site sides ; which we find in the writings of Ptolemy, and which was employed in the trigonometry of the Greeks. In comparatively modern times we find the same proposi¬ tions distinctly recognised in the Opus Palatinum, the great work on triangles begun by Rhetius, and finished by Otho, who published it in 1596; also in the trigonometry of Pitiscus, first printed in 1599; and probably they may¬ be found in still earlier works. Montucla, in his Histoire des Mathematiques, says, “ I do not see that any one be¬ fore the beginning of this century (the 18th) had thought of seeking formulae proper to express the sines or cosines, tangents or co-tangents, of the sum or difference of arcs of a circle, or their powers, &c. It seems to me to have been very natural; and that there must have been frequently occasion to know what was the sine or cosine, the tangent or co-tangent, of an arc, that was the sum or difference of two arcs of which the sines or cosines, or tangents or co¬ tangents, were known. The first theorems on this subject appear to be the work of Frederic-Christian Mayer, one of the first members of the Petersburg Academy.” Mon¬ tucla, however, seems to have overlooked the trigonome¬ try of Pitiscus, who, in problems 8 and 9 of his second book, gives rules for finding the sines and cosines of the sum and difference of two arcs, when the sines and cosines of the arcs are given. These are in the edition of 1612. The formula which expresses the tangent of the sum of several arcs by the tangent of the arcs themselves, wras given, for the first time, we believe, by John Bernoulli, in the Leipsic Acts for July 1722. Both these are prior to Mayer’s Memoir, which is in the Petersburg Commentaries with the date 1727. It was probably here, however, that the first essay of analytical trigonometry was given. Euler, who stands pre-eminent in every branch of the mathema¬ tics, has contributed more especially to this doctrine, as in his Subsidium Calculi Sinuum, in the New Petersburg Commentaries, vol. v. (for 1754 and 1755), and his Intro- ductio in Analysin Infinitorum. The doctrine of spherical trigonometry was given in an analytic form by the same writer, in a memoir entitled Trigonometria Spherica uni- versa ex primis principiis derivata, in the Petersburg Acts for 1779; and also by De Gua in the volume of the Academy of Sciences for 1783; and, lastly, by Lagrange in a memoir of the Journal Polytechnique, vol. ii. 217. The calculus of sines is of great importance as a branch of analysis. It enables us in a great measure to dispense with the complicated diagrams which the earlier writers on geometry, and on the physico-mathematical theories, employed in their investigations and demonstra¬ tions. In geometry, when combined with the modern analysis, it gives the power of expressing the most com¬ plicated relations of figure, and magnitude, and position, almost without the help of graphic representations. As an example, we may give the fine discovery b}r Gauss, of formulae by which a regular polygon of seventeen sides may be inscribed in a circle by a geometrical construction. In algebra it has served to extend greatly the theory of equations; in astronomy, when applied to the theories of the planets and comets, it gives elegant and convenient expressions for their angular motions, and compact for¬ mulae for computing the elements of their orbits, and their true and apparent positions ; and in statics and dynamics, it gives, without diagrams, the relations of forces which produce rest or motion, and the laws of the motions. The precious invention of logarithms abridged the irksome 486 ALGEBRA. Algebra, labour of calculation, even in the simplest applications of . geometry; but this, combined with the trigonometrical tables, and the theory of the calculus of sines, affords a still more powerful instrument for abridging labour; just as two mechanical inventions, which apart can overcome considerable resistance, yet are vastly more potent when united. 218. In the calculus of sines, as well as in other appli¬ cations of algebra to geometry, all quantities, whether lines or angles, are considered as expressed by numbers ; some line or angle is assumed as a unit, and the number of times that unit is contained in the line or angle is its numerical value. The magnitude of the unit is altogether arbitrary; and since, in general, the magnitude to be expressed in num¬ bers may not contain the unit an exact number of times, v it ought to be so small, that the remainders may, in re¬ spect of the wholes, be rejected. 219. The primary unit, by which angles are expressed in numbers, is one ninetieth part of a right angle, that is, one 360th part of four right angles. Each of these is called a degree, and is conceived to contain 60 units of a lower order, called minutes ; and each minute, again, 60 units of the next lower order, called seco7ids ; and so on to thirds, &c. The degrees, minutes, &c. in an angle, are usually writ¬ ten thus: 12° 15' 10" 25"'. This means an angle of 12 degrees, 15 minutes, 10 seconds, and 25 thirds. It is not common to estimate angles to a greater degree of accu¬ racy than seconds and tenths of a second: thus 3-4" means three seconds and four tenths of a second. The French mathematicians attempted, in the time of the Revolution, to introduce a new unit for angles. They supposed a right angle to be divided into 100 equal parts, called degrees; and each degree to be subdivided into 100 minutes ; and each minute into 100 seconds ; and so on. This division, however, was not adopted out of France. Unfortunately, Laplace had employed it in his Mecanique Celeste, to the inconvenience of its readers; but now the French mathematicians themselves have al¬ most all returned to the old sexagenary division. 220. Although an angle and a circle are not necessarily related, because we can form a distinct notion of each independently of the other ; yet there is such an analogy between them, as to make it convenient to consider them together. Therefore (Plate XVIII. fig. 23), let PO, QO, be straight lines which contain an angle whose vertex is O. Let OQ, one of the lines, be given in position, and let OE, a segment of the other line adjacent to O, be an invariable magnitude. Let us now suppose the line PO to coincide at first with QO, and, departing from that position, to turn about O as a centre: the line PO will now generate an angle POQ, and E, the extremity of the constant radius, will describe an arc AE. When the line has made a complete revolution about the cen¬ tre O, it will have generated four right angles, and the point E will have described a complete circle; and it is manifest that any angle POQ will have the same ratio to four right angles that the arc AE has to the whole cir¬ cumference. Flence it follows that the arc may conve¬ niently serve as a geometrical measure of the angle; and if we suppose the circumference to be divided into 360 equal parts, called degrees, and each of these to be sub¬ divided into 60 minutes, and so on, then the angle and arc will be expressed by the same number of degrees, minutes, &c. 221. Let the diameters AC, BD, be perpendicular to each other. These divide the circumference into four quadrants, and the circle into four regions AOB, BOC, COD, DOA. The difference between an angle and a Aid right angle, or between an arc and a quadrant, is called^ the complement of the angle or arc; and the difference between an angle and two right angles, or between an arc and a semicircle, is called the supplement of the angle or arc. Thus, the angle POB is the complement of POQ, and POC is its supplement; and the arc BE is the com¬ plement of AE, and CE its supplement. 222. Assuming A as the origin of the variable arc AE, a straight line EF, drawn from its extremity E, perpen¬ dicular to the diameter AC, is called the sine of the arc AE ; and a straight line EG, drawn perpendicular to BD (which is the sine of the arc EB, the complement of AE), is called the cosine of the arc AE. Hence it appears that the cosine of an arc is equal to the distance of the sine from the centre of the circle. 223. Supposing now the arc AE to increase continual¬ ly by the revolving of the radius OE, departing from the position OA, and moving in the direction ABCD, &c. the sine EF, which at first is z=0, will increase until the arc become a quadrant; afterwards, while the arc increases from one to two quadrants, the sine E'P will decrease, and at last again become =0. The arc continuing to in¬ crease, the sine will be reproduced; but its direction PE" will now be the opposite to its first direction FE. It will increase in magnitude, until the arc become three qua¬ drants ABCD ; and it will again decrease, while the arc is increasing from three to four quadrants: and when the radius has made a complete revolution, the sine will have decreased to zero. We may, however, suppose the re¬ volving radius OE still to proceed : there will thus be ge¬ nerated an arc, ABCDAE, greater than a complete circum¬ ference, of which EF will be the sine; and, in the second and every succeeding revolution, the sine will pass through the same changes as in the first. 224. We may trace the changes in the magnitude and direction of the cosine just in the same way. While the arc AE increases from zero to a quadrant, the cosine OF, at first equal to the radius OA, decreases, and at last va¬ nishes ; and while the arc continues to increase, and has any value ABE' between one and two quadrants, the co¬ sine OF' is reproduced, with a direction the opposite to the first. When the arc is exactly two quadrants, the co¬ sine becomes in magnitude OC, equal to OA, but oppo¬ site in direction. The arc still increasing to ACE", the cosine decreases to OF"; and when the arc becomes ABCD, three quadrants, the cosine again becomes =0: between three and four quadrants the cosine OF'" re-ap- pears in its original direction ; and when the revolution is completed, the cosine acquires its first value OA. In a second revolution the same changes are repeated, and so on continually. We may suppose the radius to turn round O in the con¬ trary direction ADC, and the very same changes will be produced on the direction and magnitude of the sine and cosine of the generated arc AE'". 225. In conformity to the principles of analytic geome¬ try, the contrary position of the arcs AE, AE', and the sines EF, E'F', in respect of the position of the arcs AE , AE'", and the sines E"F", E'"F"', may be indicated by the signs and —; and the same is true of the cosines OF, 04"'", which are opposed in direction to the cosines OF, OF", the arcs and sines on opposite sides of the diame¬ ter AC being regarded as having opposite signs, and a like contrariety being supposed in the cosines on opposite sides of the diameter BD, which is perpendicular to AG The arc AE being regarded as positive, it does not signi¬ fy whether we reckon the sines and cosines positive or ne¬ gative in the beginning, provided we change the signs, ALGEBRA. 487 Au a. when, after having decreased to zero, they are reproduced capable of continual increase.

Let us suppose the sine and cosine of any positive arc AE in the first quadrant to be positive; then, from what has been explained, the sine will continue to be positive in the second quadrant, but the cosine will have become negative; in the third the sine and cosine will both be negative; and in the fourth the sine will be negative, but the cosine positive. Again, if the radius OE turn about O in the contrary direction, ADCB, &c. the arc AE'", &c. thus generated will be negative; the sines will also be negative in the first semicircle, but the cosines positive in the quadrant AD, and negative in DC, and so on ; the changes from -f- to —, and from — to +, following each other exactly as in the generation of a positive arc. 226. Let a straight line AH, perpendicular to the dia¬ meter AC, meet the radius OE produced in H (fig. 24); the line AH is called the tangent of the arc AE, and the line OH the secant of that arc. 227. A line BK, perpendicular to OB (which is at right angles to OA), and which meets OH in K, will be the tangent of the complement of the arc AE ; and OK will be its secant. The former is therefore called the co-tan- gcnt of the arc AE, and the latter its co-secant. 228. The segment AF of the diameter, between the be¬ ginning of the arc and its sine, is called the versed sine of the arc; and, similarly, the segment BG, the versed sine of the complement, is its co-vcrsed sine. 229. Since the arc AE is assumed as a geometrical measure of the angle POQ, we may regard the lines which are the sine, tangent, secant, Sec. of the arc, as also the sine, tangent, secant, &c. of the angle ; or, since all quan¬ tities in this calculus are to be expressed in numbers, we may take any numbers proportional to these lines. Hence arc AE we may assume the fraction rad.OA EF as the measure of the angle POQ, and, similarly, as the sine of the an¬ gle POQ, its cosine, its tangent, and its secant; then will be the co-tangent, and HO = will be the co-secant of the angle. These quanti¬ ties will have among themselves the same ratios as the lines which bear the same designations; and it is evident, fiom the nature of similar figures, that supposing the an¬ gle POQ to remain of the same magnitude, its sine, tan¬ gent, secant, &c. thus defined, are the same, whatever be the magnitude of the circle, which now serves merely to connect them as related quantities. We may consider OA, the radius of the circle, as a unit, and then the sines, tangents, &c. will be expressed in parts of that unit, according to the decimal notation. his is the common form in which they are given in the trigonometrical tables. 230. Die power of algebra, as an instrument of inves¬ tigation, depends greatly on the proper employment of conventional signs: it is common to express the sine of un arc a by the abbreviation sin. a, its cosine by cos. a, its ngent by tan. c, its secant by sec. a, its co-tangent by cot. a, 1 s co-secant by cosec. a, and its versed sine by ver. sin. a. . 3h From the definition given of an angle by the an¬ cient geometers, its measure cannot exceed half the cir- cum erence of a circle. When, however, we regard an g e as generated by the rotation of a line about a fixed P01nt, the arc, which is its measure, may be regarded as motion of the sun and planets is reckoned from an angle' or arc of 0° forward to 360°. We are thus led to con¬ sider the sines of arcs which exceed 180°, and even which exceed a whole circumference, or any number of circum¬ ferences. 232. Let vr denote half the circumference of the circle which is assumed as a scale for measuring angles. It is easy, by induction, to infer from what has been explain¬ ed, that a being any arc, Sin.

We shall next investigate formulae for the succes¬ sive integer powers of the cosine and sine of an arc. By formula (1) of (E) we have, making n=l, 2 cos.2a zr cos. 2a-j-1. Let both sides be multiplied by 2 cos. a, the result is 4 cos.3a = 2 cos. a cos. 2a -f 2 cos. a / cos."a= cos. (n — 4)a, These are given in the following table : (Z) Cos. a — cos. a, 2 cos.2a = cos. 2a +1, 4 cos.3a = cos. 3a -j- 3 cos. a, 8 cos.4a zz cos. 4a-j-4 cos. 2a-J-3, 16 cos.5a zz cos. 5a + 5 cos. 3a+10 cos. a, 32 cos.6a zz cos. 6a-f 6 cos. 4a-f-15 cos. 2a-j- 10, 64 cosJa zz cos. 7a+ 7 cos. 5a 4-21 cos. 3a-f-35 cos. a, &c.

The series is to be continued until we come to a nega¬ tive arc, and if n be an even number, the half of the co¬ efficient of the last term (viz. that in which the arc zz 0a) is to be taken. 259. Next, for the powers of the sine; from (2) of (E), we have 2 sin.2azz — cos. 2a -j- 1: multiply both sides by 2 sin. a ; then, 4 sin.3 a zz — 2 sin. a cos. 2a+ 2 sin. a. Now, by formula (4) of (E), 2 sin. a cos. 2a zz sin. 3a — sin. a; therefore 4 sin.3 a zz — sin. 3a+ 3 sin. a. Again, multiplying both sides by 2 sin. a, ’8 sin.4 a zz — 2 sin. a sin. 3a+ 6 sin. a sin. a. But by formula (2) of (E), 2 sin. a sin. 3a zz — cos. 4a+cos. 2a, and 6 sin. a sin. a zz — 3 cos. 2a + 3; therefore 8 sin.4 a zz cos. 4a — 4 cos. 2a+3. In this way we may form the following table; (A 2) Sin. a zz -f- sin. a, 2 sin.2 a zz — cos. 2a + 1, 4 sin.3 a zz — sin. 3a + 3 sin. a, ■') 8 sin.4 a zz 4- cos* 4a — 4 cos. 2a + 3, 16 sin.5 a zz sin. 5a — 5 sin. 3a + 10 sin. a, 32 sin.6 a zz — cos. 6a 4* 0 cos. 4a — 15 cos. 2a + 10, 64 sin.7 a zz — sin. 7a + 7 sin. 5a — 21 sin. 3a 4* 35 sin. a.

The introduction of the imaginary symbol —1 into analysis, has given great assistance in all investiga¬ tions connected with the calculus of sines.

Let us now assume that 1, so that v—V—1, and v =. ; the two last formulae will become The other equation gives us Cos. a—v sin. a—x—vy, Cos. 2a—v sin. 2a—(x—vyf, Cos. 3a—v sin. %a—\x—vy)z ; and in general, Cos. ma—v sin. ma—(x—vy)m. (5) Formulae (4) and (5), when the quantities denoted by x, y, and v, have been restored, may stand thus; (B 2) Cos. wa-j-V'-— 1 sin. wan (cos. a-fv'—1 sin. a)n, Cos. 7ia—V— 1 sin. war=(cos. a—V—1 sin. a)”. These have been investigated on the hypothesis that n is a whole positive number, but they are also true when n is a fraction, or negative; for we have manifestly % Cos. a +V—1 sin, in. a < ^ (=< —(cos. na +V-1 sin. na)n :(cos. wza-j-V'— 1 sin. ma)”1: therefore, raising these equal expressions to the power m, we have Cos.

We may even extend the proof to the case of n, an irra¬ tional quantity; for every such quantity may be express¬ ed to any degree of nearness by numbers. 262. These very remarkable and important expressions (B 2) were first found by Abraham de Moivre, and ap¬ peared in his Miscellanea Analytica, which was published in 1730. He was led to them by considering the ana¬ logy between the circle and hyperbola; but we owe to Euler their introduction into analysis as elementary for¬ mulae. By taking their sum and difference, we obtain them in a different shape, as follows; - (C 2) • v, ^ (cos.a+V—1 sin.a)"-|-(cos.a—V— 1 sin.a) .

In either case, they are purely symbolical expressions «J of the kind found by Cardan’s rule for the roots of a cu¬ bic equation belonging to the irreducible case. (Sect. XI.) Like them, they cannot be immediately applied to calcu¬ lation ; but when treated by the rules of analysis, they re¬ veal some of the most elegant and recondite theorems in geometry. 263. The formulae (C 2) admit of an immediate appli¬ cation to the determination of the cosine and sine of any multiple of an arc. Let a?=cos. a, y=sin. a, so that y)»+Q- (E 2) 2 cos. na pn + qn p* pn' 1 Sin. na: (x+V — 1 y)n—(x — V — 1 ^)n 2/y/~ Now, by the binomial theorem, (x-\-V— 1 y)n—xn-{-nzn~l yV — 1- n(w—l)(n —2) I • 2 • 3 ^ —- ) xn~ l - 2~X V — 1 -j-, &c. n(n— 1) 1 • 2 3 -2^2 (x — V— ly)nz=.xn—naf1 ~1 yV— 1 - n(n — l)(w — 2) , . . + ~ 1 2 . 3—^n_3yV —1+, &c.

By continuing the series, we come to the cosines of negative arcs, which are exactly the same as the cosines of positive arcs having the same co-efficient: Thus, cos. (m — n)a = cos. (n — m)a, for each is equal to cos. ma cos. na + sin. ma sin. a. Now, in the series which is the expansion of (p-\-q)n, the terms at equal distances from the first and last have the same co-efficient; there¬ fore the series for (2 cos. a)n must have the same proper¬ ty ; and further, the cosines of the arcs at equal distances from the extremes are, as has been just proved, equal; we may therefore omit the terms which are the cosines of negative arcs, and in their stead take the doubles of these, which are the cosines of positive arcs. The above formula will then be abbreviated to (2 cos. a)n=2 [cos. na-\-d cos. (n — 2)a-{-the G«goriaa Algebra ^ + 3—f + i—iV+^&C. for one eighth of the circumference.

This converges somewhat faster than Gregory s series; but Newton says that the addition of no fewer than 5000,000,000 of the terms would be re¬ quired to give the length of the quadrant true to twenty decimal places of figures; a labour which would require about one thousand years. 272. The simplicity of Gregory’s series is a great re¬ commendation ; and as the determination of the ratio of t ie alameter of a circle to the circumference is a problem of primary importance, we shall investigate an auxiliary formula, which will make it the fittest of any for the solu¬ tion. Let n, x, y, be three whole numbers, such, that the arc whose tangent is — is equal to the sum of the arcs whose 1 r , • * 2^— 1 Here the cosine and sine are expressed by imaginary exponentials. Lagrange considered these formula? to be the happiest analytical inventions of the age. The series for the cosine and sine fiom which they have been here i deduced had been given by Newton before the end of tangents are - and -; then, by formula (F), the 17th century. They might therefore then have been X y found, and a perfection given to this subject which it did not attain until fifty years later, by the labours of Euler. 270.

This elegant expression for an arc of a circle was first tound by James Gregory, from whom it was received by ollins, an eminent mathematician of that period, in the beginning of 1671. It was sent to Leibnitz in 1675 fsee Cammercium Epistolicum, p. 98 and 120), and it ap¬ pears tlnit this celebrated person had communicated the same senes to his friends on the Continent as his own dis- ^0ve7’and even sent it to England in 1676.

He believed it to be new, and indeed it was not then known in this country; but it had been given before by Euler, in his Opuscula Analytica, tom. i. p. 350. This series converges pretty fast; for the tangent of the half of an arc being less than half the tangent of the whole arc, as is easily proved, each term is less than one fourth of the term before it. As, however, the series proceeds, the ratio of any two consecutive terms ap¬ proaches continually to that of 4 to 1 ; and hence any term somewhat advanced in the series will be nearly three times the sum of all that follow it; and, by this property, as soon as a term is found to be nearly one fourth of that before it, one third of that term will give the sum of all that follow it, very near. From the formula tan. ^a=cosec. a — cot. a (sect. 249), we set tan. ^ a —VT -f cot.2a — cot.«=cot. a^l-j-tan.2«—1).

The equation ?j + ^=:2 cos. x gives v2 — 2v cos. 1—0. Now, since the two equations v2m — 2vm cos. mx 4-1 = 0, v2 —2v cos. a;-{-1 = 0, require to be both satisfied at the same time, they must have at least one common root. Let a be that root, then i will also be a root of both ; for putting them under the a form vm4-— 2 cos. mxzzO, ‘vm v +- — 2 cos. x=0, V the results will be the very same whether we substitute a or - for v. a Now the quadratic equation v2 — 2v cos. a; +1=0 can only have two roots, therefore these must also be roots of the equation v2m— 2vm cos. mx-\-1=0 ; hence it follows that the trinomial — 2vm cos. mx-\-1 must be divisible by this other expression, v2 — 2v cos. a? 4-1 ; a or, putting mx = = 1, and the trinomial v1™ — 2vm cos. p 4* 1 becomes in this case vhn — 2vm 4- 1 = — l)2j and the factors are v2 — 2v 1 = (v — l)2, 2v v2 — 2v cos. — + 1, m v2 — 2v cos. -— +L m — 2v cos. 2{m— 1) w -f L If, again,

The two last formulae are the analytic expressions of a very remarkable property of the circle discovered by Cotes, the friend and contemporary of Newton, and called the CotesianTheorem.

( reprisals, by sending a number of galleys and galliots to the coast of Provence, where they committed the most dreadful ravages, and brought away a vast number of captives ; upon which a new armament was ordered to be prepared at Toulon and Marseilles against the next year; and the Algerines, having received timely notice, put themselves in as good a state of defence as the time would allow. In May 1683, Du Quesne, with his squadron, cast an¬ chor before Algiers; where, being joined by the marquis d’Affranville at the head of five stout vessels, he resolv¬ ed to bombard the town next day. Accordingly, 100 bombs were thrown into it the first day, which did ter¬ rible execution ; while the besieged made some hundred discharges of their cannon without doing any consid¬ erable damage. The following nights the bombs were again thrown into the city in such numbers, that the dey’s palace and other great edifices were almost de¬ stroyed; some of their batteries were dismounted, and several vessels sunk in the port. The dey and Turkish bashaw, as well as the whole soldiery, alarmed at this dreadful devastation, sued for peace. As a prelimi¬ nary, the immediate surrender of all Christian captives who had been taken fighting under the French flag was demanded; which being granted, 142 of them were immediately delivered up, with a promise of sending the remainder as soon as they could be got from the different quarters of the country. Accordingly Du Quesne sent his commissary-general, and one of his engineers, into the town; but with express orders to insist upon the delivery of all the French captives without exception, together with the effects taken fr6m the French; and that Mezo- morto, the admiral, and Hali Rais, one of their captains, should be given as hostages. This last demand having embarrassed the dey, he as¬ sembled the douwan, and acquainted them with it; upon which Mezomorto broke out into a violent passion, and told the assembly that the cowardice of those who sat at the helm had occasioned the ruin of Algiers; but that, for his part, he would never consent toTleliver up any thing that had been taken from the French. He immediately acquaint¬ ed the soldiery with what had passed; which so exaspe¬ rated them, that they murdered the dey that very night, and next day chose Mezomorto in his place. The new dey immediately cancelled all the articles of peace, and hostilities were renewed with greater fury than ever. The French admiral now kept pouring in such volleys of bombs, that in less than three days the greater part of the city was reduced to ashes; and the fire burnt with AW such vehemence, that the sea was illumined by it for more than two leagues around. Mezomorto, unmoved at all these disasters, and the vast number of the slain, whose blood ran in rivulets along the streets, or rather growing furious and desperate, sought only revenge; and, not content with causing all the French in the city to be cruelly murdered, ordered their consul to be tied hand and foot, and fastened alive to the mouth of a mortar, whence he was shot away. By this piece of inhumanity Du Quesne was so exasperated, that he did not leave Al¬ giers till he had utterly destroyed their fortifications, shipping, almost all the lower, and above two-thirds of the upper part of the city, by which means it became little else than a heap of ruins. The haughty Algerines were now thoroughly convinced Treat that they were not invincible ; they therefore immediately "Ah sent an embassy into France, begging in the most abjectlant5- terms for peace, which Louis immediately granted, to their inexpressible joy. They now began to pay some re¬ gard to other nations, and to be a little cautious how they wantonly incurred their displeasure. The first bombard¬ ment by the French had so far humbled the Algerines, that they condescended to enter into a treaty with Eng¬ land, which was renewed upon terms very advantageous to the latter in 1686. It is not to be supposed, however, that the rooted perfidy of the Algerines would at once disappear. Notwithstanding this treaty, they lost no opportunity of making prizes of the English ships which they could conveniently reach. Upon some outrage of this kind, Captain Beach drove ashore and burnt seven of their frigates in 1695, which produced a renewal of the treaty five years after ; but it was not till the taking of Gibraltar and Port Mahon that Britain could have a sufficient check upon them to enforce the observation of treaties, and they have since paid a greater deference to the English than to any other European power. The eighteenth century furnishes no very remarkable events with regard to Algiers, except the taking of the city of Oran from the Spaniards in 1708 (which, however, they regained in 1737), and the expulsion of the Turkish bashaw, and uniting his office to that of dey, in 1710. This introduced the form of government which still con¬ tinues in Algiers. _ The dey is now absolute monarch, and transmits to the Gove Porte only some annual presents. His own income Pro‘™e”J bably rises and falls according to the opportunities he has&c.' of fleecing both natives and foreigners; whence it is va¬ riously computed by different authors. Dr Shaw com¬ puted the taxes of the whole kingdom to bring into the treasury no more than 300,000 dollars; but he supposed that the eighth part of the prizes, the effects of those persons who die without children, joined to the yearly contribu¬ tions raised by the government, presents from foreigners, fines and oppressions, may bring in about as much more. Both the dey and officers under him enrich themselves by the same methods of rapine and fraud. The first deys were elected by the militia, who were then called the douwan, or common council. This elective body was at first composed of 800 militia officers, without whose consent the dey could do nothing; and.upon some urgent occasions all the officers residing in Algiers, amounting to above 1500, were summoned to assist. But since the deys have become more powerful, the douwan is principally composed of thirty chiah bashaws or co o- nels, with the mufti and cadi upon some emergencies, and on the election of a dey, the whole soldiery am allowed to give their votes. All the regulations or sta e ought to be determined by that assembly before tiey ALGIERS. Ai rs. pass into a law, or the dey has power to put them in V execution: but for many years back the douwan has been of little account, and has been only convened for form’s sake, to give assent to what the dey and his chief favou¬ rites have previously concerted. The method of gather¬ ing the votes in this august assembly is perfectly agree¬ able to the character of those who compose it. The aga or general of the janizaries, or the president pro tempore, first proposes the question, which is immediately re¬ peated with a loud voice by the chiah bashaws, and from them echoed again by officers called bashaldalas. From these the question is repeated from one member of the douwan to another, with strange contortions and the most hideous growlings if it does not meet their appro¬ bation. These assemblies seldom end without some tumult or disorder. As the whole body of the militia is concerned in the election of a new dey, it is seldom car¬ ried on without blows and bloodshed; but when once the choice is made, the person elected is saluted with the words Alla Barick, “ God bless and prosper you and the new dey usually causes all the officers of the douwan who had opposed his election to be strangled, filling up their places with those who had been most zealous in promoting it. From this account of the elec¬ tion of the deys, it cannot be expected that their govern¬ ment should be at all secure. As they arrive at the throne by tumult, disorder, and bloodshed, they are generally deprived of it by the same means, scarcely one in ten having the good fortune to die a natural death. The officer next in power to the dey is the aga of the janizaries, who is one of the oldest officers in the army, and holds his post only for two months. He is then suc¬ ceeded by the chiah, or next senior officer. During the two months in which the aga enjoys his dignity, the keys of the metropolis are in his hands, all military orders are issued out in his name, and the sentence of the dey upon any offending soldier, whether capital or not, can only be executed in the court of his palace. As soon as he has gone through this short office, he is considered as mazoul, or superannuated; receives his pay regularly, like the rest of the militia, every two months; is exempted from all fur¬ ther duties, except when called by the dey to assist at the grand council, which he has, however, a right to attend at all times, though he has no longer a vote. Ihe religion of the Algerines is chiefly distinguished from that of the Turks by a greater variety of supersti¬ tious rites. The Koran is their acknowledged rule of faith and practice; but they are not very scrupulous in the observance of it. The mufti or high-priest, the cadi or_ chief judge, and the grand marabout, are the three principal officers who preside in matters of religion. ; orsj i, The corsairs or pirates form a number of small republics, ”nir ce> °f each of which the rais or captain is the supreme bashaw, who, and the officers under him, compose a kind of douwan, jn which every question relating to the vessel is decided, fhese corsairs carry on likewise the commerce of Algiers, importing whatever commodities are brought into the kingdom, either by way of merchandise or prizes. These consist chiefly of gold and silver stuffs, damasks, cloths, spices, tin, iron, plated brass, lead, quicksilver, cordage, sail-cloth, bullets, cochineal, linen, tartar, alum, rice, sugar, soap, cotton raw and spun, copperas, aloes, brazil and log¬ wood, vermilion, &c. Very few commodities, however, are exported from this part of the world; the oil, wax, odes, pulse, and corn produced, being but barely sufficient .° suPply the country; though before the loss of Oran f ie merchants have been known to ship off from one or otier of the ports of Barbary several thousand tons of corn. The consumption of oil, though produced in great 509 Relijk abundance, is internally so considerable, that it is seldom Aimers, permitted to be exported to Europe. The other exports consist chiefly in ostrich feathers, copper, rugs, silk sashes, embroidered handkerchiefs, dates, and Christian slaves Some manufactures in silk, cotton, wool, leather, &c. are carried on in this country, but mostly by the Spaniards settled there, especially about the metropolis. Carpets are also a manufacture of the country; and, though much inferior to those of Turkey both in beauty and fineness, are preferred by the people on account of their being both cheaper and softer. There are also at Algiers looms for velvet, taffetas, and other wrought silks ; and a coarse sort of linen is likewise made in most parts of the kingdom. The country furnishes no materials for ship-building. They have neither ropes, tar, sails, anchors, nor even iron. When they can procure enough of new wood to form the main timbers of a ship, they supply the rest from the ma¬ terials of prizes which they have made, and thus produce new and swift-sailing vessels from the ruins of the old. The population of Algiers cannot be ascertained with much accuracy; but the following estimate of its amount, and the classes into which it is divided, has just appeared in the Annales des Voyages:— Moors and Arabs, husbandmen and artisans,... 1,200,000 Independent Arabs, 400,000 Berbers settled in villages, 200,000 Jews, 30,000 Turks and renegadoes composing the ruling power,.,20,000 Descendants of the above, but of an inferior class,..20,000 1,870,000 The Barbary corsairs, in the course of the eighteenth century, had ceased to exercise their vocation on the same extended scale*as formerly. Their strength, in conse¬ quence of the vast increase in the naval power of the great European states, had been reduced to comparative insignificance. They no longer domineered over the high seas, nor attempted to annoy the vessels belonging to any of the great powers; nor did the latter any longer deign to purchase immunity by a disgraceful tribute. Yet there were still within the circle of the Mediterranean several populous and wealthy, yet feeble states, which lay an easy prey to their ravages. These were particularly the king¬ doms of the Sicilies and Sardinia. Not content with cap¬ turing their vessels in the open sea, the corsairs made descents upon their shores, sweeping off not only property, but all persons of every age, sex, and rank, who could be valuable in the market as slaves. Europe, engrossed by the mightier evils in which it was involved during thirty years of war, bestowed comparatively little attention on this partial distress. At the Congress of Vienna, however, when the peace of the Continent appeared to be esta¬ blished on a permanent basis, the attention of the sove¬ reigns was laudably drawn-to every quarter from which it could suffer disturbance. That in question, by which numerous individuals, often of a respectable place in so¬ ciety, were torn from their homes, immured in dungeons, and exposed to every outrage which barbarous bigotry and brutal licence might prompt, could not fail to appear of the first magnitude. The Congress, having been unex¬ pectedly broken up, did not come to any final decision. The subject, however, continued to be agitated in the councils of Britain, and her gallant officers who had been employed' in the Mediterranean strongly represented the propriety of interference. The Dutch, at the same time, her now friendly neighbours, cordially concurred in pro¬ moting this common interest of humanity. The first step taken was to send squadrons under Lord Exmouth to Algiers, and Sir Thomas Maitland to Tunis, 510 ALGIERS. Algiers, with a demand for the general liberation of the slaves ac¬ tually in bondage, and the entire discontinuance, for the future, of this detestable trade. Overawed by the immense power with which they knew these demands to be support¬ ed, they returned a conciliatory answer. They dismissed a number of slaves actually in thew hands, and engaged that only the final sanction of the Porte should be wanting to abolish for ever the system of Christian slavery. The British commanders then returned to England with their fleets, which were immediately laid up. Tunis, which had imbibed some portion of European humanity and civilisation, and was better aware of its real interests and position, adhered very tolerably to the terms stipulated. But Algiers, bred in rapine, furiously re¬ pelled a system which opened to its rovers the fearful prospect of being obliged to earn a subsistence by honest industry. So dreadful was the ferment, that a plan, it is said, had been formed to assassinate Lord Exmouth on his way to the ship. The dey, raised from the dregs of the soldiery, and sharing all their barbarism, allowed full scope to their violence, and sought only to secure himself against its effects. He formed alliances with the Porte, the emperor of Morocco, and other leading Mussulman potentates ; he strengthened Algiers with new works, and prepared to brave the utmost fury of the Christian powers. Under these precautions, the system of Christian piracy was commenced with redoubled activity, to compensate for the late suspension, and to repair the loss of the slaves who had been given up. The Algerine soldiery, in their blind fury, had recourse to an outrage still more terrible. A number of vessels, belonging to Naples and other Me¬ diterranean states, had been in the practice of assembling at Bona to carry on the pearl fishery, in which, upon pay¬ ment of an annual tribute, they were protected by the Al¬ gerine state. Suddenly these peaceful and industrious fishermen were surrounded by a band of Moors, who com¬ menced an indiscriminate massacre, which could not be justified on any ground or pretence, and seems to have had no object but to show their implacable hatred to the Christian name. As soon as the tidings of this dreadful outrage arrived in England, they kindled at once a just indignation, and a expedition, determination to follow up to the utmost the measures projected against this common pest of the civilized world. Lord Exmouth’s fleet was re-equipped with almost incre¬ dible dispatch. Early in July 1816 he sailed with five ships of the line and eight smaller vessels, and arrived at Gib¬ raltar in the beginning of August, when he was joined by a Dutch fleet of six frigates under Admiral Capellen. Hav¬ ing remained at Gibraltar a short time, to make some ne¬ cessary preparations, Lord Exmouth sent forward Captain Dashwood, of the Prometheus, to bring away, if possible, the consul and his family.. Captain Dashwood was strict¬ ly interrogated as to Lord Exmouth’s armament, of which the dey had received information from a French vessel, and from other quarters. He contrived to evade the questions; and, though he found it impossible to obtain the consul’s release, managed to bring off his wife and daughter, disguised in the uniform of naval officers. An attempt was also made to carry off his infant child in a basket, but it betrayed itself by its cries; however, the dey, with unusual humanity, allowed the child to follow its mother. The consul himself was thrown into close confine¬ ment. The dey, meantime, was exerting himself in the most extraordinary manner to put the place in a posture of defence. The batteries on the mole, and all other points commanding the harbour, were strengthened and enlarg¬ ed ; and armed men, to the number of forty thousand, were brought in from the surrounding country. Lord Ex¬ mouth’s Lord Exmouth, being detained by calms and contrary Ah winds, did not anchor in front of Algiers till the 26th, when^ he sent in a flag of truce under cover of the Severn gun- brig, with a peremptory demand of certain conditions which, however, were extremely moderate. They con¬ sisted in the final abolition of Christian slavery—tfie im¬ mediate liberation of all slaves now within the territory of Algiers—the repayment of all ransoms obtained since the commencement of the year—the liberation of the consul and all British subjects now in confinement. On the Severn arriving in front of the mole, the captain of the port came out to meet the English, and invited them to enter the city. Salame, the interpreter, declined, but presented the conditions, demanding that an answer should be sent within an hour. The captain, not without some reason, replied that this was a period wholly inade¬ quate to decide on so important a demand. Hereupon two or three hours were allowed; and two were declared by the captain to be sufficient. Meantime, a favourable breeze having sprung up, Lord Exmouth moved forward his ships to within a mile of the harbour, where he held himself ready for action. Salame waited three hours and a half, when no boat appearing from the land, he steered for the fleet, making signals of the failure of his mission; after which, steps were immediately taken for commenc¬ ing operations. Algiers was fortified in the strongest manner, and by all the resources of nature and art. The mole, consider¬ ed a masterpiece of defensive architecture, was encircled by four batteries, respectively of 44, 48, 66, and 60 guns. All the range of steeps facing the sea, on which the city was built, were covered with batteries, which could keep up a united fire on an assailing fleet. Lord Exmouth, undismayed, bore up into the centre of this mighty line of defence, and placed the Queen Charlotte within fifty yards of the mole,—a bold and happy position, where her own fire wras more effective than elsewhere, and many of the principal Turkish guns could not bear upon her. The other ships took their stations in line; while the Dutch squadron, which could not find room in front of the mole, was detached to the flanks, to occupy the fire of batteries which might otherwise have borne on the English. The fleets were placed in this formidable array, yet all was still silent, and the surrounding heights were crowded with spectators, who came as to a show. Lord Exmouth began to hope that the dey was yet to yield, when three shots were fired from the batteries. They were instantly returned, and a fire commenced, as animated and well supported as was ever witnessed. The British navy, pitched against these iron walls, underwent as hard and doubtful a struggle as it had ever maintained against the strongest array of hostile fleets. The atmosphere was filled with so thick a smoke, as to render it im¬ possible for one ship to discern the position of another. About sunset Admiral Milne communicated that his ves¬ sel, the Impregnable, had lost 150 killed and wounded, and that he stood in urgent need of a frigate to divert some part of the fire now directed against them. Soon, however, the enemy’s efforts began to slacken; the principal batteries were successively silenced; ship after ship caught fire, till the flame spread over the whole fleet, and reached the arsenal; the harbour and bay were illumined by one mighty and united blaze. At ten o’clock, seven hours after the commencement of this hard combat, the destruc¬ tion of the Algerine naval force was complete; but as some distant batteries still kept up a harassing fire, Lord Exmouth gave the signal to steer out into the bay, whic i was speedily accomplished. Next morning Lord Exmouth, confident that the dey rs. ALGIERS. Alf:! \jr\ r3. was now sufficiently humbled, sent a letter, in wdiich, after enumerating the heavy wrongs which had called forth this signal chastisement, he repeated the moderate terms already offered; adding, that in the event of their being now accepted, three guns should be fired as a signal. This letter was sent in the same boat as the day be¬ fore, with instructions to wait three hours. As soon as the English boat was seen, another came out having on board the captain of a frigate, who received the letter, and intimated that there was no doubt of its terms being com¬ plied with; pretending even that, had a little longer time been allowed the day before, the conflict would have been unnecessary. Accordingly, in an hour and a half three shots were fired, and a boat immediately came out, on board of which were the captain of the port and the Swedish consul. All the demands were granted; and the dey in vain attempted, on various pretexts, to evade or delay their execution. The captives, to the number of 1083, were set at liberty ; ransoms amounting to 383,500 dollars were repaid to Sicily and Sardinia; the consul was liberated, and received a compensation for the insults he had endured: in fine, a treaty was signed, by which the dey bound himself to discontinue the practice of Chris¬ tian slavery, and hereafter to treat prisoners of war ac¬ cording to the established practice of civilized nations. In this desperate contest the English lost 128 killed and 690 wounded, the Dutch 13 killed and 52 wounded. Lord Exmouth received two slight hurts, and his clothes were cut with several balls. The enemy lost four frigates, five large corvettes, and 30 gun-boats. All their arsenals were consumed, and their principal batteries reduced to a state of ruin. The city also was greatly injured, Salame having counted no less than thirty shots which had pass¬ ed through the walls of the consul’s house. The Algerines, notwithstanding this severe and merit¬ ed chastisement, did not long adhere to sentiments of mo¬ deration. No time was lost and no effort spared to place the city in a more formidable, state of defence than ever; and they considered themselves again in a condition to set even the great powers at defiance. Annoyances were begun against the trench trade; and the consul having made remonstrances on the subject, was grossly insulted. France then declared war, and sent a fleet against Algiers; but the fortifications on the sea-side were so strong, that for more than a year her ships fcould only prolong an ineffec¬ tive blockade. At length war on a great scale was re¬ solved on. A large fleet under Admiral Duperre, and a land force of upwards of 30,000 men under General Bour- mont, then minister at war, sailed from Marseilles in the end of May 1830, After some delay in the bay of Palma m Majorca, this armament reached the coast of Africa, and the troops began to land bn the morning of the 14th June, upon the western side of the peninsula of Sidi Fer- rueh, in the bay of Torre Chica. The disembarkation be¬ gan at a quarter past four, and continued till twelve. The Algerines at first showed only flying parties of horse, which retreated before the fire of tw o steam-vessels. Afterwards they opened a somewhat brisk fire from several batteries, winch having kept up for several hours, not without some mss on the part of the French, they retreated. I he army continued for some days landing their pro¬ visions and stores, with only slight annoyance from flying froops of cavalry. On the 19th, however, the Turkish troops in Algiers being reinforced by the contingents of the beys o Umstantina, Oran, and Titterie, a general attack was made with a force of 40,000 or 50,000 men. They advan- ped, outflanking the French army, and charged with such impetuosity as to penetrate the line at several points. Af- er a very obstinate conflict they wTere compelled to re¬ treat, and their camp taken and plundered. The French admit a loss of 60 killed and 450 wounded; and the son of the commander-in-chief died of his wounds. The Algerine troops renewed their attacks on the 24th and 2oth, when, after hard combats, they were again re¬ pulsed. The French then advanced upon Algiers, on the 29th the trenches were opened, and at four in the morning of the 4th July the batteries began their fire, which was returned with much vigour. At ten the fort called Em¬ peror, being no longer defensible, was blown up by the enemy, with a tremendous explosion. The French com¬ mander took possession of its ruins, wdiere he receiv¬ ed a flag of truce: before the close of the day a treaty wtis concluded for the entire surrender of Algiers; and next day, 5th July, the French flag waved on its forts. Twelve ships of war, 1500 brass cannon, and a large treasure, came into the hands of the conquerors. The Turkish troops were permitted to go wherever they pleas¬ ed, provided they left Algiers; and the dey chose Naples for his place of retirement, while most of the soldiers de¬ sired to be landed in Asia Minor. The bey of Titterie submitted, but the French have not as yet (August 1830) made any attempt to penetrate into the interior. Algiers, the capital of the above kingdom, is pro¬ bably the ancient Icosium; by the Arabians called Al- gezair, or rather Al-Jezier or Al-Jezerah, i. e. the island, because there was an island before the city, to which it has since been joined by a mole. It is built of white stone, on the declivity of a hill fronting the sea, in the form of an amphitheatre, and from the sea resembles a ship under sail. The houses rise above each other in such a manner that each from its flat roof commands a view of the sea. The streets are so narrow as scarcely to admit two persons to walk abreast. There is no good water in the city; and though there is a tank or cistern in every house, yet a want of water is often felt, because it rains but seldom. The chief supply is from a spring on a hill, the water of which is conveyed by pipes to above a hundred fountains. The dey’s palace and the seraglio form the finest buildings, and are curiously adorned with marble pillars. The houses are square, and built of stone and brick, with a square court in the middle, and galleries all around. There are said to be about 80,000 inhabitants in the city, comprehending 5000 Jewish families, besides Christians. The armed Turks amounted to above 6000, who, with the Moorish troops, raised the garrison to 14,000 or 15,000 men, 2000 of whom were cavalry. Without the city there is a great number of sepulchres, as also cells or chapels dedicated to marabouts or reputed saints. Long. 3. 30. E. Lat. 36. 49. N.

Iroquois, on the other hand, were to pay a tribute to their allies, out of the culture of the earth, and to perform for them all the menial duties, such as flaying the game, curing the flesh, and dressing the skins. By degrees, however, the Iroquois associated in the hunting matches and warlike expeditions of the Algonquins; so that they soon began to fancy themselves as tvell qualified, either for war or hunting, as their neighbours. One winter a large detachment of both nations having gone out a hunt¬ ing, and secured, as they thought, a vast quantity of game, six young Algonquins and as many Iroquois were sent out to begin the slaughter. The Algonquins, probably becoiAe a little jealous of their associates, upon seeing a few elks, desired the Iroquois to return, on pretence that they would have sufficient employment in flaying the game they should kill ;• but after three days’ hunting, having killed none, the Iroquois exulted, and in a day or two privately set out to hunt for themselves. The Algonquins were so exasperated at seeing their rivals return laden with game, that they murdered all the hunters in the night-time. The Iroquois dissembled their resentment; but, in order to be revenged, applied themselves to study the art of war as practised among those savage nations. Being afraid of engaging with the Algonquins, at first they tried their prowess on other inferior nations, and, when they thought themselves sufficiently expert, attack¬ ed the Algonquins with such diabolical fury as showed they could be satisfied with nothing less than the exter¬ mination of the whole race; which, had it not been for the interposition of the French, they would have accom¬ plished.

It is on an elevated plain, enjoys a most salubrious climate, and is surrounded by fields most abun¬ dantly productive of wheat and barley. Near it are some medicinal baths of great and ancient celebrity, to which invalids still resort. It was a most important fortress when the Moors ruled Granada, and its capture by the Christians was the most decisive step in the reduction of their power. It contains 4500 inhabitants, and is situated in lat. 36. 42. N. long. 2. 46. W. * ALHAMBRA, the ancient fortress and residence of the Moorish monarchs of Granada. It derives its name from the red colour of the materials with which it was originally built, Alhambra signifying a red house. It ap¬ pears to a traveller a huge heap of as ugly buildings as can well be seen, all huddled together, seemingly without the least intention of forming one habitation out of them. The walls are entirely unornamented, all gravel and peb¬ bles, daubed over with plaster by a very coarse hand; yet this is the palace of the Moorish kings of Granada, indisputably the most curious place within that exists in Spain, perhaps in the world. In many countries may be seen excellent modern as well as ancient architecture, both entire and in ruins; but nothing to be met with any¬ where else can convey an idea of this edifice, except the decorations of an opera, or the tales of the genii. Passing round the corner of the emperor’s palace, one is admitted at a plain, unornamented door in a corner. On my first visit, says Mr Swinburne (Travels in Spain), I confess I was struck with amazement, as I stept over the ALH threshold, to find myself on a sudden transported into aAlhai species of fairy land. The first place you come to is the1^ court called the communa or del mesucar, that is, the com¬ mon baths ; an oblong square, with a deep basin of clear water in the middle ; two flights of marble steps leading down to the bottom; on each side a parterre of flowers, and a row of orange trees. Round the court runs a peri¬ style paved with marble; the arches bear upon very slight pillars, in proportions and style different from all the regu¬ lar orders of architecture. The ceilings and walls are in- crustated with fretwork in stucco, so minute and intricate that the most patient draughtsman would find it difficult to follow it, unless he made himself master of the general plan. This would facilitate the operation exceedingly * for all this work is frequently and regularly repeated at cer¬ tain distances, and has been executed by means of square moulds applied successively, and the parts joined together with the utmost nicety. In every division are Arabic sentences of different lengths, most of them expressive of the following meanings: “ There is no conqueror but God;” or, “ Obedience and honour to our lord Abouab- doulah.” The ceilings are gilt or painted, and time has caused no diminution in the freshness of their colours, though constantly exposed to the air. The lower part of the walls is Mosaic, disposed in fantastic knots and fes¬ toons. A work so novel, so exquisitely finished, and so different from all that he has ever seen, must afford a stranger the most agreeable sensations while he treads this magic ground. The porches at the ends are more like grotto-work than any thing else to which they can be compared. That on the right hand opens into an octagon vault, under the emperor’s palace, and forms a perfect whispering gallery, meant to be a communication between the offices of both houses. Opposite to the door of the communa through which you enter, is another leading into the quarto de los leones, or apartment of the lions, which is an oblong court, 100 feet in length and 50 in breadth, environed with a colon¬ nade seven feet broad on the sides and 10 at the end. Two porticoes or cabinets, about 15 feet square, project into the court at the two extremities. The square is paved with coloured tiles, the colonnade with white mar¬ ble. The walls are covered five feet up from the ground with blue and yellow tiles, disposed chequerwise. Above and below is a border of small escutcheons, enamelled blue and gold, with an Arabic motto on a bend, signifying, “ No conqueror but God.” The columns that support the roof and gallery are of white marble, very slender, and fantastically adorned. They are nine feet high, including base and capital, and eight inches and a half in diameter. They are very irregularly placed; sometimes singly, at others in groups of three, but more frequently two to¬ gether. The width of the horse-shoe arches above them is four feet two inches for the large ones, and three for the smaller. The ceiling of the portico is finished in a much finer and more complicated manner than that of the com¬ muna, and the stucco laid on the walls with inimitable de¬ licacy ; in the ceiling it is so artfully frosted and handled as to exceed belief. The capitals are of various designs, though each design is repeated several times in the cir¬ cumference of the court, but not the least attention has been paid to placing them regularly or opposite toeaci other. Not the smallest representation of animal life can be discovered amidst the varieties of foliages, grotesques, and strange ornaments. About each arch is a large squj>r^ of arabesques, surrounded with a rim of characters, t a are generally quotations from the Koran. Over me pi - lars is another square of delightful filligree work, thg e up is a wooden rim, or kind of cornipe, as much enric e C F Alha^ra- \s- A L H with carving as the stucco that covers the part underneath. v^Over this projects a roof of red tiles, the only thing that disfigures this beautiful square. This ugly covering is a modern addition made by a late prime minister, who a few years ago gave the Alhambra a thorough repair. In Moorish times the building was covered with large paint¬ ed and glazed tiles, of which a few are still to be seen In the centre of the court are twelve ill-made lions muz¬ zled, their fore parts smooth, their hind parts rough, which bear upon their backs an enormous basin, out of which a lesser rises. While the pipes were kept in good order, a great volume of water was thrown up, that, falling down into the basins, passed through the beasts, and issued out of their mouths into a large reservoir, where it communi¬ cated by channels with the jets d'eau in the apartments. This fountain is of white marble, embellished with many festoons and Arabic distiches. Passing along the colonnade, and keeping on the south side, you come to a circular room occupied by the men as a place for drinking coffee, &c. A fountain in the middle refreshed the apartment in summer. The form of this hall, the elegance of its cupola, the cheerful distribution of light from above, and the exquisite manner in which the stucco is designed, painted, and finished, exceed all power of description. Every thing in it inspires the most pleasing, voluptuous ideas; yet in this sweet retreat they pretend that Abouabdoulah assembled the Abencerrages, and caused their heads to be struck off into the foun¬ tain. Continuing your walk round, you are next brought to a couple of rooms at the head ‘of the court, which are supposed to have been tribunals, or audience-cham¬ bers. Opposite to the scda de los Abencerrages is the entrance into the torre de las dos hermanas, or the tow er of the two sisters; so named from two very beautiful pieces of marble, laid as flags in the pavement. This gate exceeds all the rest in profusion of ornaments, and in beauty of prospect which it affords through a range of apartments, where a multitude of arches terminate in a large window open to the country. In a gleam of sunshine, the variety of tints and lights thrown upon this enfilade are uncommonly rich. j he first hall is the concert room, where the women sat; the musicians played above in four balconies. In the middle is ayeA d’eati. The marble pavement is equal to the finest existing, for the size of the flags and evenness of the co,our. The two sisters, which give name to the room, are slabs that measure 15 feet by seven and a half, with¬ out flaw or stain. The walls, up to a certain height, are mosaic, and above are divided into very neat compartments o stucco, all of one design, which is also followred in many 0 tlle adjacent halls and galleries. The ceiling is a fret¬ ted cove. To preserve this vaulted roof, as well as some m the other principal cupolas, the outward walls of the towers are raised ten feet above the top of the dome, and support another roof over all, by which means no danger can ever be caused by wet weather or excessive heat and cold. From this hall you pass round the little myrtle garden of Lindaraxa, into an additional building made to >e east end by Charles V. The rooms are small and low. is dear motto, Plus outre, appears on every beam. This cads to a little tower projecting from the line of the north 'ail, called el tocador, or the dressing-room of the sultana.

I he look-out is charming. In one corner is a maj^e flag, drilled full of holes, through which the i 10 e. . perfumes ascended from furnaces below; and ere, it is presumed, the Moorish queen was wont to sit v1-1^ and sweeten her person. The emperor caus- ed this pretty room to be painted with representations of Alhambra his wars, and a great variety of grotesques, which appear |] to be copies, or at least imitations, of those in the Wme Alhazen. of the \ atican. From hence you go through a long pas-v ^ — sage to the hall of ambassadors, which is magnificently de¬ corated with innumerable varieties of mosaics, and the mottoes of all the kings of Granada. This long narrow anti-chamber opens into the communa on the left hand, and on the right into the great audience-hall in the tower of Comares; a noble apartment, 36 feet square, 36 high up to the cornice, and 18 from thence to the centre of the cupola. The walls on three sides are 15 feet thick, on the other nine; the lower range of windows 13 feet high. The whole wall is inlaid with mosaic of many colours, efis- posed in intricate knots, stars, and other figures. In every part various Arabic sentences are repeated. Having thus completed the tour of the upper apart¬ ments, which are upon a level with the offices of the new palace, you descend to the lower floor, which consisted of bed-chambers and summer-rooms : the back stairs and pas¬ sages, that facilitated the intercourse between them, are without number. The most remarkable room below is the king s bed-chamber, which communicated by means of a gallery with the upper story. The beds were placed in two alcoves, upon a raised pavement of blue and white tiles; but as it was repaired by Philip V. who passed some time here, it cannot be said how it may have been in former times. A fountain played in the middle, to refresh the apartment in hot weather. Behind the alcoves are small doors, that conduct you to the royal baths. These consist of one small closet with marble cisterns for wash¬ ing children, two rooms for grown up persons, and vaults for boilers and furnaces that supplied the baths with water and the stoves with vapours. The troughs are formed of large slabs of white marble; the walls are beautiful with party-coloured earthen ware: light is admitted by holes in the coved ceiling. Hard by is a whispering gallery, and a kind of labyrinth, said to have been made for the diversion of the women and children. One of the passages of communication is fenced off with a strong iron grate, and called the prison of the Sultana; but it seems more probable that it was put up to prevent any body from climbing into the division allotted to the women. Under the council-room is a long slip, called the kings study ; and adjoining to it are several vaults, said to be the place of burial of the royal family. In the year 1574 four sepulchres were opened; but as they contained no¬ thing but bones and ashes, they were immediately closed again. This description of the Alhambra may be finished by observing how admirably every thing was planned and calculated for rendering this palace the most voluptuous of all retirements; what plentiful supplies of water were brought to refresh it in the hot months of summer; what a free circulation of air was contrived, by the judicious disposition of doors and windows; what shady gardens of aromatic trees; what noble views over the beautiful hills and fertile plains. No wonder the Moors regretted Granada! no wonder that they still offer up prayers to God every Friday for the recovery of this city, which they regard as a terrestrial paradise !

ALHAZEN, an Arabian author of the 11th century, who is better entitled to the appellation of philosopher than most of those of his countrymen by whom it has been obtained. The place of his birth was Bassora; the 3 T 514 A L I A L I Alhazen year uncertain; but his death took place at Cairo in 1038. ed who among them would undertake to be his companion, \\ There was another author of the same name, who trans- Ali exclaimed, “ O prophet, I will be thy attendant; the^ Ali* lated the Almagest of Ptolemy; but that writer lived man who dares to rise against thee I will break his legs, during the reign of the caliph Almamon.

But after the cable scheme, he feigned madness, thereby to avoid the death of the latter, he was saluted caliph by the chiefs of punishment which he dreaded; and he continued to play the tribes and companions of the prophet, when he was {his humiliating part till the caliph’s death relieved him repairing to the mosque of Medina at the hour of prayer, from his apprehensions.

It appears from Casiri Abu Moussa ascended the pulpit, and cried, “ As I draw that his works were numerous; but only twm of them this ring from my finger, so I depose both Ali and Moar have been printed, namely, his treatise on Optics, and wiyah from the caliphate.” When Amru ascended, he that on the Twilight.

An unexpected event terminated the existing disputes. ALI, the son of Abu Taleb, is one of the most cele- Three Kharejites one day conversing together concern- brated characters in Mahometan history. He was cousin ing the blood which had been shed, and the impending to Mahomet, and at the age of fourteen engaged with calamities, resolved to assassinate Ali, Moawiyah, an youthful ardour in his cause. When Mahomet first re- Amru, the three authors of the present disasters. 1 ey vealed his prophetic character to his friends, and inquir- provided themselves with poisoned swords, and hasten A L I A to accomplish their purpose. Moawiyah was wounded, V^-^but the wound did not prove fatal. A friend of Amru fell in his stead. Ali was fatally wounded at the door of the mosque; and, in the 63d year of his age, he ex¬ pired on the fifth day after his wound, a. d. 660, he- gira 40. Ali had eight wives besides Fatimah, and left a nu¬ merous family, who were very remarkable for their va¬ lour. He also rose to high eminence for learning and wisdom; and of his works there are still extant a hun¬ dred maxims, a collection of verses, and a prophecy of all the great events which are to happen to the end of time. The Mussulmans term Ali the heir of Mahomet, and the accepted of God; and his particular followers have possessed various states in Africa and Asia, and the Per¬ sian part of the Usbec Tartars ; and some sovereigns of India are at present of the sect of Ali. A monument is raised upon his tomb near Kufa, which the kings of Per¬ sia have successively decorated and religiously revered. Near the ruins of Kufa, a city named Meshed Ali has been built to his memory. Some of his deluded followers imagine that he is still alive, and that he will revisit the earth and fill the same with justice. A green turban still continues to distinguish the descendants of Ali. Ali Bey, an eastern adventurer, is said to have been a native of Mount Caucasus, and about the age of twelve or fourteen he was sold for a slave in Cairo. The two Jews who became his masters presented him to Ibra¬ him, then one of the most respectable men in the king¬ dom. In the family of this powerful man he received the rudiments of literature, and was also instructed in the military art. Both in letters and military skill he made rapid improvement. He gradually gained the affection of his patron to such a degree, that he gave him his freedom, permitted him to marry, promoted him to the rank of governor of a district, and afterwards by election he was raised to the elevated station of one of the governors of provinces. Deprived of his protector by death, and engaging in the dangerous intrigues that pave the way to power in that unstable government, he procured his own banishment to Upper Egypt. Here he spent two years in maturing his schemes for future great¬ ness; and in 1766, returning to Cairo, he either slew or expelled the beys, and seized the reins of government. Emboldened by success, he rescued himself from the power of the Porte, coined money in his own name, and assumed the rank of sultan of Egypt. Occupied in more important concerns, the Porte made no vigorous opposition to his measures, and Ali Bey seized this fa¬ vourable opportunity to recover a part of the Said, or Upper Egypt, which had been taken away by an Arab sheik. Next he sent out a fleet from Suez, which seizing upon Djedda, entered the port of Mecca; while a body of cavalry, commanded by Mohammed Bey, his favourite, took and plundered Mecca itself. A young Venetian uierchant laid before him a plan of reviving the ancient trade to the East Indies through the Mediterranean and hed Sea. Having formed an alliance in 1770 with one Sheik Daher, a rebel against the Porte in Syria, he uimed at the conquest of all Syria and Palestine. He rst endeavoured to secure Gaza; then his army, forming a junction with that of Daher at a place called Acre, ad¬ vanced to Damascus. On the 6th of June 1771 a battle was fought at this place with the Turkish pachas, and A °hammed and Daher, the commanders of Ali Bey, routed them with great slaughter. They instantly took possession of Damascus, and the castle itself had also capitulated, when all on a sudden Mohammed hastened ALI 515 Alicante. back to Egypt with all his Mamelukes. Some ascribe Aljameia tins strange conduct to an impression made upon Mo- " hammed by the Turkish agents, and others to a report of the death of Ah Bey. ^ Although unsuccessful, Ali Bey never lost sight of his favourite object; and Mohammed, losing his confidence was forced to save his life by exile. Mohammed, how¬ ever, quickly returned with an army, and drove Ali Bey from Cairo. In this unfortunate s.tate of affairs Ali Bey fled to Daher, and, combining their forces, they attacked the Turkish commander at Sidon, and came off victorious, although the Turkish army was three times their num¬ ber. After a siege of eight months, they next took the town of Jaffa. Deceived by letters from Cairo, which were only intended to ensnare him, and stimulated with recent victories, he returned to Cairo. Entering the de¬ serts which divide Gaza from Egypt, he was furiously attacked by a thousand chosen Mamelukes led on by Murad Bey, who \fas enamoured with the beauty of Ali’s wife, and had obtained the promise of her, provided that he could, take Ali Bey captive. Murad wounded and made Ali Bey prisoner, and carried him up to Moham¬ med, who received him with affected respect; but in three days, either in consequence of poison or the effects of his wounds, Ali breathed his last. ALJAMEIA is a name which the Moriscoes in Spain give to the language of the Spaniards. Among other articles agreed on by thejunta which was appointed by the emperor Charles V. in* 1526, in favour of the Moris¬ coes, this was one, that the Moriscoes should no longer speak Algavareia, i. e. Moorish, or Arabic; but should all speak Aljamria, i. e. Spanish, as it was called by the Moors, and all their writings and contracts should be in that language. ALIAS, in Law, a second or further writ issued from the courts of Westminster, after a capias, &c. sued out without effect. ALIBI, in Law, denotes the absence of the accused from the place where he is charged with having commit¬ ted a crime; or his being elsewhere, as the word imports, at the time specified. ALICANTE, a city of Spain, in the province of Valen¬ cia, with a port on the Mediterranean Sea. The city forms a half-moon on the sea-shore, and is defended by a castle 1000 feet in height, built on a rock; and the bay in which vessels are anchored is well protected by various batteries. The commerce of this port is very consider¬ able, and its exports are consigned to every port of the north of Europe. Two lakes on the coast furnish a large supply of salt made from evaporation, which is conveyed by English and Swedish ships. A fertile plain called the Luerta, near the city, which has been furnished with the means of irrigation at a vast expense, is covered with vines, which produce excellent wines; with mulberry trees, which rear silk-worms; and with great quantities of almonds, olives, figs, and raisins, that supply articles for foreign commerce. On the coast near this city, the island of Plana, a barren rock, supplies the most beautiful marbles in great varieties. The coast furnishes large quantities of barilla, which is one of the most important branches of the commerce of the city. As the exportable commodities engage the principal attention of the agri¬ culturists, the quantity of corn grown is insufficient for the consumption of the city and its vicinity, though rice might be raised to a vast extent; and the wheat is brought partly from La Mancha, and partly by sea from Africa and from Italy. The castle of Alicante is in long. 0. 3. 51. E. and in lat. 38. 20. 41. N. This city contains 1 cathedral, 3 parish churches, 6 hot springs, and 516 A L I ALL Aliquant. Alicante- 17,345 inhabitants.

ALICANTERILLA, a town of Spain, in the province of Murcia, with 3000 inhabitants; nine miles south of Murcia. ALICATA, a city of Sicily, in the intendancy of Cala- tanisera. It is a seaport and a parliamentary city, at the mouth of the river Salso, from which corn, fruit, and sul¬ phur are exported. There is a roadstead, but no harbour. It contains 11,000 inhabitants. Near it are the vestiges of the ancient city of Gela. Alicata, a mountain of Sicily, near the valleys Me- zara and Noto, upon which was situated, as is generally thought, the famous Dacdalion, where the tyrant Phalaris kept his brazen bull. ALIEN, in Law, implies a person born in a strange country, not within the king’s allegiance; in contradis¬ tinction to a denizen or natural subject. An alien is in¬ capable of inheriting lands in Britain till naturalized by an act of parliament. No alien is entitled to vote at the election of members of parliament; nor can he enjoy any office, or be returned on any jury, unless where an alien is party in a cause, when the inquest is composed of an equal number of.denizens and aliens. The act 33 Geo. III. c. 4, commonly called the Alien Bill, and which empowered the king to restrain aliens, and send them out of the kingdom, was, by 41 Geo. III. c. 24, appointed to be continued till six months after the conclusion of a general peace. ALiEn-Duty, an impost laid on all goods imported by aliens, over and above the customs paid for such goods imported by British subjects, and on British bottoms. Alien Priories, a kind of inferior monasteries, formerly very numerous in England, and so* called from their be¬ longing to foreign abbeys. ALIENATION, in Law, denotes the act of making over a man’s property in lands, &c. to another person. Alienation in Mortmain, is the making over of lands, &c. to a body politic, or to a religious house. Alimentarii Pueri, &c. were certain children main¬ tained and educated by the munificence of the emperors, in a sort of public places not unlike our hospitals. Tra¬ jan was the first who brought up any of these alimentary boys. He was imitated by Adrian. Antoninus Pius did the same for a number of maids, at the solicitation of Faustina ; and hence, in some medals of that empress, we read pvellae favstinianae.—Alexander Severus did the like at the request of Mammasa; and the maids thus educated werer called Mammceance. Alimentary Duct or Canal, is a name given by Dr Tyson and some others to that part of the body through which the food passes from its reception into the mouth to its exit at the anus ; including the gula, stomach, and intestines. See Anatomy. Alimentary Law, lex alimentaria, was an old law among the Romans, whereby children were obliged to find sustenance for their parents. ALIMENTS. See Dietetics. ALIPILARIUS, or Alipilus, in Roman Antiquity, a servant belonging to the baths, whose business it was, by means of waxen plasters, and an instrument called volsel- la, to take off the hair from the arm-pits, and even arms, legs, &c. this being deemed a point of cleanliness. ALIPTERIUM, dkuvTri^o'j, in Antiquity, a place in the ancient palestra;, where the athletce were anointed before their exercises. ALIQUANT Part, in Arithmetic, is that number which cannot measure any other exactly without some remain- All der. Thus, 7 is an aliquant part of 16 ; for twice 7 wants two of 16, and three times 7 exceeds 16 by 5. All-jf ALIQUOT Part, is that part of a number or quantity B which will exactly measure it without any remainder. Thus, 2 is an aliquot part of 4, 3 of 9, 4 of 16, &c. ALISONTIA, or Alisuntia, in Ancient Geography, a river of Belgic Gaul, now Alsitz ; which, rising on the borders of Lorraine, and running through that duchy, wa¬ ters the city of Luxemburg, and, swelled by other rivu¬ lets, falls into the Sour. ALITES, in Roman Antiquity, a designation given to such birds as afforded matter of auguries by their flight. ALKADARII, a sect among the Mahometans who deny any eternal, fixed, divine decrees, and are assertors of free-will: The word is formed from the Arabic alhidar, which signifies “ decree.” The Alkadarii are a branch of Motazalites, and stand opposed to the Algiabarii. ALKAHEST, or Alcahest, among alchemists, deriv¬ ed from a word which signifies spirit of salt or all spirit, was supposed to be a universal menstruum, capable of resolving all bodies into their principles. Van Helmont pretended he was possessed of such a menstruum. It is likewise used by some authors for all fixed salts volati¬ lized. ALKALI, in Chemistry, denotes a particular class of salts. The word alkali is of Arabian origin, and was in¬ troduced into chemistry after it had been applied to a plant which still retains the name of kali. When this plant is burnt, the ashes washed in water, and the water evaporated to dryness, a white substance remains, which is called alkali. See Chemistry. ALKALIMETER, a name given to a small instru¬ ment, invented by M. Descroizilles for ascertaining the value of the alkalies in commerce. There is an account of it in the 60th volume of the Annales de Chimie, which is translated in the 28th volume of Tilloch’s Philosophical Magazine.

ALL-Hallow, or All-Saints, a festival celebrated on the first of November, in commemoration of all the saints in general. The number of saints being so excessively multiplied, it was found too burdensome to dedicate a feast-day to each. In reality, there are not days enough, scarce hours enough, in the year, for this purpose. Hence an expedient was had recourse to, by commemorating such in the lump as had not their own days. Boniface IV., in the ninth century, introduced the feast of All- Saints in Italy, which was soon after adopted in the other churches. Ahh-Saints, islands near Guadaloupe, in the West In¬ dies. ALL-Saints, a parish in Georgetown district, South Ca¬ rolina, containing 2225 inhabitants, of whom 429 are whites, and 1795 slaves. It sends a member to each house of the state legislature.

It is reckoned one of the richest and most fertile captainships in all Brazil, ALL 41 ouls producing great quantities of cotton and sugar. The bay itself is about two and a half leagues over, interspersed All.abad. wjth a number of small but pleasant islands, and is of pro- /"^digious advantage to the whole country.

ALLA, or Allah, the name by which the professors of Mahometanism call the Supreme Being. The term Alla is Arabic, derived from the verb alah, to adore. It is the same with the Hebrew Eloah, which signifies the Adorable Being. ALLAGNA, a town in the province of Val Sesia, in the principality of Piedmont, in Italy. It has some rich cop¬ per mines, with gold mixed in the same ore. It is on the river Sesia, and contains 1600 inhabitants. ALLAHABAD, a large province of Hindostan, which is situated between the 24th and 26th degrees of N. lat. It is bounded on the north by the provinces of Oude and Agra, on the south by the Hindoo- province of Gund- wana, on the east by the provinces of Bahar and Gund- wana, and on the west by the provinces of Malwah and Agra. It may be estimated in length at 270 miles, by 129 the average breadth. The principal geographical and political subdivisions of Allahabad are the following: 1st, The District of Allahabad ; 2d, Benares ; 3d, District of Mirzapoor ; 4th, District of Juanpoor ; 5th, The Re- wah Territory; 6th, District of Bundelcund; 7th, District of Cawnpoor ; 8th, Manicpoor Territory. The surface of this province is unequal. Along the shores of the Ganges and Jumna the country is flat and extremely fertile; but to the south-west, in the Bundel¬ cund territory, the land rises, and is diversified with high hills, which abound in strongholds. This mountainous re¬ gion contains the famous diamond mines of Pannah. Its climate is also more temperate than that of the lower plains, which are extremely sultry, and subject to hot winds. The province is in many parts well watered. The prin¬ cipal rivers in the north are the Ganges, the Jumna, the Goomty, and the Caramnassa, besides other streams of inferior note, which, supplying abundant moisture, diffuse fertility over several of the subdivisions, especially those of Benares and Allahabad. In the high country water is scarce, and the principal rivers are the Kena and Goggra. The husbandman consequently depends for supplies of moisture on the periodical rains, or on wells, which are often sunk to a great depth. On the whole, however, Allahabad may be classed among the most pro¬ ductive provinces of India. The exports are, diamonds, saltpetre, opium, sugar, indigo, cotton, cotton-cloths, &c. The imports are various, consisting of European manu¬ factures, salt from the maritime ports of Bengal being one of the staple articles in regular demand. The prin¬ cipal towns within this province are, Benares, Allahabad, Gallinjer, Chatterpoor, Juanpoor, Mirzapoor, Chunar, and Ghazipoor. The inhabitants are estimated at 7,000,000, the proportion being one Mahometan to eight Hindoos. In remote times this province held a high rank, as it contained Allahabad and Benares, two of the most venerated places °f Brahminical pilgrimage. The province is now com¬ prehended within the British jurisdiction, with the excep¬ tion of a small portion of the Bundelcund division, which is held by petty chiefs under British protection. A L L 517 It is mentioned by Abul Tazel, that the territory which Allahabad, now forms the province of Allahabad was invaded inv-*~v-N^ the year 1020 by Sultan Mahmood of Ghizni. He re¬ turned in 1023, but made no permanent establishment. It was afterwards subdued by the Patan emperors of Delhi, and swallowed up in the Mogul empire, of which it was formed into a distinct province by the emperor Acbar, under the_ name of Allahabad, which it still re¬ tains. On the dissolution of the Mogul dynasty, the northern quarter was taken possession of by the nabobs of Oude. But in 1764, through the interference of Lord Clive with the nabob of Oude, Korah and Allahabad were ceded to Shah Allum, the nominal though fugitive sovereign of Delhi. In 1772 they reverted to the nabob of Oude; and in 1775 the Bengal government acquired the Benares districts by treaty with Azoph-ud-Dowlah, and Allahabad and the adjacent districts in 1801 by cession, from his successor on the throne of Oude. The south-eastern districts were received from the Mahratta peshwa in 1803, in exchange for a tract of equal value in the Carnatic, above the Ghauts and Gujerat. (Hamil¬ ton’s Geographical, Statistical, and Historical Description of Hindostan.') (*■.) Allahabad, a fortified town of Hindostan, in the province of Allahabad, most favourably situated in a dry and healthy soil, on a triangle, at the junction of the two mighty streams, the Ganges and the Jumna. It has been occasionally the residence of royalty, and still contains some fine ruins; but it never appears to have been a great and magnificent city, and has now a desolate and ruinous appearance, having obtained among the natives the name of Fakeerabad, or Beggar abode. The city is small, with very poor houses, and narrow, irregular streets, confined to the banks of the Jumna. Nine-tenths of the present native buildings are of mud, raised on the foundations of more substantial brick edifices, which have long ago fallen to decay. The port, which is placed at the distance of a quarter of a mile, on a tongue of land washed by the Jumna and the Ganges, is lofty and extensive, and completely com¬ mands the navigation of the two rivers. It is strong both by nature and art, and has a noble castle. It has gained as much in strength as it has lost in appearance by some modern improvements which it has undergone, by which its lofty towers have been lowered into bastions and ravelins, and its high stone ramparts covered with turf parapets, and obscured by a green sloping glacis. It is still, however, according to Bishop Heber, a striking place, and its principal gate, surmounted by a dome, with a wide hall beneath, surrounded by arcades and galleries, and orna¬ mented with rude but glowing paintings, forms a noble entrance to a place of arms. The barracks are handsome and neat. On one side is a large range of buildings, which are still in the oriental style, and contain some noble vaulted rooms, chiefly occupied as officers’ quarters, and overlooking from a considerable height the rapid stream and craggy banks of the Jumna. The principal mosque, which is still in good repair, is but little fre¬ quented. This building, which is solid and stately, but without much ornament, is advantageously situated on the banks of the Jumna, adjoining the city on one side, and an esplanade before the glacis of the fort on the other. It was at one time the residence of the general of the station, but has since been restored to its original destination. The finest buildings in the neighbourhood are the sultan’s serai and garden. The former is a noble quadrangle, with four fine Gothic gateways, surrounded within an embattled wall by a range of cloisters for the accommo¬ dation of travellers, the whole now in a dilapidated con¬ dition. Adjoining the serai is a neglected garden, plant- 518 ALL Allaire ed with fine old mangoe trees, in wdiich are three beauti- II ful tombs, raised over two princes and a princess of the Allan, imperial family. The houses of the civil servants of the company are at some distance both from the fort and the town. Allahabad is one of the most noted resorts of Hindoo pilgrimage. It owes its celebrity to the confluence of three sacred rivers, the Ganges, the Jumna, and the Se- reswati. This latter river is no longer to be seen; but the Hindoos assert that it joins the other two under ground, and that consequently the same religious merit is acquired by bathing at this sacred confluence as by bathing in all the three separate rivers. From this super¬ stition a shameful tax is collected by government, of three rupees, for permission to bathe in the river; and crowds of pilgrims collect for this purpose from all quarters. They amounted in 1812—13 to 218,792; and by their eagerness to rush into the river to bathe, they exposed themselves to risks which were sometimes fatal. Ihe gross amount of the receipts amounted in 1812—13 to 221,066 rupees. In 1815-16 they had fallen off to 79,779 rupees. Allahabad is now the permanent station of the British court of justice, which makes an annual circuit through the province for deciding suits between the natives. Allahabad was taken in the year 1765 by the British army under Sir II. Fletgjier. It is 820 miles from the sea by the river. The travelling distance is only 550 miles, from Benares 53, from Lucknow 57, from Agra 296, and from Delhi 212 miles. In 1803 the population, exclusive of the garrison, amounted to 20,000.

ALLAN, David, a Scotish historical painter of con¬ siderable celebrity, was born at Alloa, on the 13th Febru¬ ary 1744. At a very early age he showed such marks of genius as attracted the notice of some gentlemen living in the neighbourhood. In a remote part of the country, and deprived of the ordinary means of indulging his pro¬ pensity to drawing, he betook himself, when a boy, to such implements and materials as he could readily procure; and the mechanical skill and taste which, in particular, he displayed in using his knife, have been mentioned as re¬ markable for his years. Mr Stewart, then collector of the Customs at Alloa, having mentioned these proofs of natural talent to Mr Foulis the printer, who some time be¬ fore had instituted an academy in Glasgow for painting and engraving, he invited young Allan to study under his care. Here he remained about seven years, studying the elementary principles of his art; and, by the proficiency which he attained, justified the opinion of his talents which had procured him admission to that ill-fated semi¬ nary. But although the public taste for the fine arts, which then existed in Scotland, was so feeble as to leave his preceptor without support, which his liberal and spirit¬ ed efforts justly claimed, Allan, on leaving the academy, had the good fortune to gain the patronage of individuals whose generosity enabled him to prosecute his views, and to improve his taste, by studying the works of art abroad. At the joint expense of several persons of fortune, parti¬ cularly Lord Cathcart and Mr Abercrombie of Tullibody, he was enabled to go to Italy; and at Rome he devoted himself with great zeal to his profession. Here he re¬ mained for no less a period than sixteen years, during which time his subsistence chiefly depended on the co¬ pies which he made from the most celebrated pictures of the ancient masters. Among the original works which he then painted, there wras one which does the highest credit ALL to his talents, and which gained for him the gold' medal All given by the Academy of St Luke, in the year 1773, for || the best specimen of historical composition. This picture Allaf represents the Origin of Painting, and is well known by's^-v the excellent engraving of it by Cunego. His design of the Calabrian Shepherds is also a composition of great merit; and his four views of the Carnivals at Rome, etched by Paul Sandby, are said likewise to have been very successful. On his return to his native country, he took up his re¬ sidence in Edinburgh, and soon after, on the death of Alexander Runciman, in 1786, was appointed director and master of the academy established by the Board of Trustees for Manufactures in Scotland. There he execut¬ ed a great variety of works, of various degrees of merit; but perhaps none such as might have been expected from the author of the Origin of Painting. Those, indeed, by which he is most known, are of a cast altogether different, being remarkable for the comic humour which they dis¬ play. The Scotch Wedding, the Highland Dance, the Repentance Stool, with his Illustrations of the Gentle Shep¬ herd, are all of this class, and so generally known, from his own spirited etchings in aqua-tinta, as to need no de¬ scription. Of his graver compositions, the Prodigal Son, in possession of Lord Cathcart, and his Hercules and Omphale, in the possession of Mr Erskine of Mar, are re¬ garded as works of great merit. As an artist, Mr Allan possessed much facility of in¬ vention, with a keen discernment of those evanescent circumstances in the outward form which mark the dif¬ ferent shades of passion and affection in the mind. With the talent of artfully arranging the various parts of a crowded and bustling scene, such as appears in some of his comic productions, he possessed that feeling for sim¬ plicity which gives to his graver compositions a classical and antique air of elegance. In his drawing he was often hasty and incorrect. He executed a great variety of etchings and drawings in water colours, which are valuable, on account of their excellent humour, and the great knowledge of national character which they express. We do not know that Allan left any pupil who has follow¬ ed his particular line in painting; but among those who received from him the rudiments of art while he conti¬ nued master of the academy, we may name the late Mr Hugh W. Williams, whose genius, however, directed him to a different course, which conducted him to high and merited distinction as a landscape painter. Mr Allan is remembered and spoken of as an excellent private character. He died at Edinburgh on the 6th of August 1796, in the 53d year of his age. Allan, a river of Perthshire, in Scotland, which passes by Dunblane, and falls into the Forth near Stirling. ALLANCHES, a town of France, in the department of the Mouths of the Rhone, and circle of Aix, six miles from Marseilles, containing 2350 inhabitants. ALLANTOIS, or Allantoides, a thin transparent bag investing the foetus of quadrupeds, as cows, goats, sheep, &c. filled with a urinous liquor conveyed to it from the bladder of the young animals by means of the urachus. ALLATIUS, Leo, keeper of the Vatican library, a native of Scio, and a celebrated writer of the 17th cen¬ tury. He was of great service to the gentlemen of Port Royal in the controversy they had with M. Claude touch¬ ing the belief of the Greeks with regard to the eucharist. No Latin was ever more devoted to the see of Rome, or more inveterate against the Greek schismatics, than Alla- tius. He never was married, nor did he take orders; ant Pope Alexander VII. having asked him one day why he did not enter into orders, he answered, “ Because ALL tus I would be free to marry.” The pope rejoined, “ If so, why do you not marry ?” “ Because,” replied Allatius, Albany «i would be at liberty to take orders.” Thus, as Mr Moftains-ga„ie observes, he passed his whole life, wavering be- tween a parish and a wife ; sorry, perhaps, at his death, for having chosen neither of them; when, if he had fixed upon one, he might have repented his choice for 30 or 40 years. If we believe John Patricius, Allatius had a very extraordinary pen, with which, and no other, he wrote Greek for forty years; at the loss of which he was so grieved as to lament it with tears. He published several manuscripts, several translations of Greek authors, and several pieces of his own composing. In his works he discovers more erudition and industry than sound judg¬ ment. His manner of writing is diffuse and perplexed, making frequent digressions from one subject to another. He died at Rome in 1669, aged 83. ALLECTUS, the prime minister and confidential friend of Carausius, emperor of Britain. In order to avoid the punishment due to the several enormous crimes with which he was chargeable, he fell upon the desperate ex¬ pedient of murdering his master, and usurping the impe¬ rial dignity, which he maintained for three years. With a design of recovering Britain, Constantius about this pe¬ riod fitted out a large squadron, which being assembled in the mouth of the Seine, the command was devolved upon the prefect Asclepiodotus. The fleet of Allectus was stationed off the Isle of Wight to receive them ; but, under the cover of a thick fog, the invaders escaped their notice, and landed in safety on the western coast, and, according to Gibbon, convinced the Britons, “ that a su¬ periority of naval strength will not always protect their country from a foreign invasion.” No sooner had the in¬ trepid commander disembarked his forces, than he set fire to his ships, and marched forward to meet the enemy. In expectation of an attack from Constantius, who command¬ ed the fleet off Boulogne, the usurper had taken his sta¬ tion in the vicinity of London ; but informed of the de¬ scent of Asclepiodotus, he made forced marches to oppose his progress. Allectus attacked the imperial troops, and his army being reduced to a small number of fatigued and dispirited men, he fell in the field, and his forces received a total defeat. Thus, in one day, and by a single battle, the fate of this great island was decided; and Britain, after a separation of ten years, was restored to the Roman empire, a. d. 297. Constantius, landing on the shores of Kent, was saluted with the loud applauses and unanimous acclamation of obedient subjects, and welcomed to the British soil. ALLEGANY Mountains, situated between the At¬ lantic Ocean, the Mississippi River, and the Lakes, are along and broad range of mountains, composed of several ridges, tending north-east and south-west, nearly parallel to the sea-coast, about 1100 miles in length, and from 110 to 150 miles in breadth. The ridges which compose this im¬ mense range of mountains have different names in the different states, viz. the Blue Ridge, the North Mountain or North Ridge, Laurel Ridge, Jackson's Mountains, and Kittatinny Mountains. All these different and immense ridges are penetrated by rivers, which appear to have forced their way through solid rocks. The principal ridge is more immediately called Allegany, and is descriptively named the Back Bone of the United States. The general name of the whole range, taken collectively, is the Alle¬ gany Mountains. Mr Evans calls them the Endless Moun¬ tain ; others have called them the Appalachian Moun¬ tains, from a tribe of Indians who live on a river which proceeds from this mountain, called the Appalachicola; nut the most common name is the Allegany Mountains. all 519 . Pass trough the states eastward of the Missis- Allegany sippi like a spine or back-bone, and give rise to nearly all River the rivers in that region. They approach the sea at the H river Hudson, but take a direction inland from that point, Allegiance‘ and in Georgia are above 200 miles from the sea. They'^"^^^ are generally covered with natural wood, and capable of cultivation, with some exceptions. The soil in the val¬ leys between the ridges is found to be superior to that between the mountains and the sea, and is indeed among the best in the United States. Towards the northern ex¬ tremity of the Alleganies, the primitive rocks cover a great breadth of country; but southward of New York they are chiefly confined to the eastern slope of the mountains. A zone of transition rocks from 20 to 40 miles in breadth extends nearly the whole length of the chain; and beyond this to the westward the country is chiefly limestone. They are not confusedly scattered, but run along in ridges generally of a uniform height, estimated on an average at 3000 feet. The ground rises to them from the sea so gradually that their height does not strike the eye much. They contain a consider¬ able variety of minerals, and on the western side great beds of coal. Allegany River, in Pennsylvania, rises on the west¬ ern side of the Allegany Mountains, and after running about 200 miles in a south-west direction, meets the Monongahela at Pittsburg, and both united form the Ohio. The lands on each side of this river, for 150 miles above Pittsburg, consist of white oak and chesnut ridges, and in many places of poor pitch pines, interspersed with tracts of good land and low meadows. ALLEGATA, a word anciently subscribed at the bot¬ tom of rescripts and constitutions of the emperors; as signata, or testata, was under other instruments. ALLEGEAS, or Allegias, a stuff manufactured in the East Indies. There are two sorts of them; some are of cotton, and others of several kinds of herbs, which are spun like flax and hemp. Their length and breadth are of eight ells, by five, six, or seven eighths ; and of twelve ells, by three fourths or five eighths. ALLEGIANCE, in Law, is the tie, or ligamen, which binds the subject to the king, in return for that protection which the king affords the subject. The thing itself, or substantial part of it, is founded in reason and the nature of government: the name and the form are derived to us from our Gothic ancestors. Under the feudal system, every owner of lands held them in subjection to some su¬ perior or lord, from whom or from whose ancestors the tenant or vassal had received them ; and there was a mu¬ tual trust or confidence subsisting between the lord and vassal, that the lord should protect the vassal in the en¬ joyment of the territory he had granted him ; and, on the other hand, that the vassal should be faithful to the lord, and defend him against all his enemies. This obligation on the part of the vassal was called his fidelitas or fealty : and an oath of fealty was required by the feudal law to be taken by all tenants to their landlord, which is couched in almost the same terms as our ancient oath of allegiance; except that in the usual oath of fealty there was fre¬ quently a saving or exception of the faith due to a supe¬ rior lord by name, under whom the landlord himself was perhaps only a tenant or vassal. But when the acknow¬ ledgement was made to the absolute superior himself, who was vassal to no man, it was no longer called the oath of fealty, but the oath of allegiance; and therein the tenant swore to bear faith to his sovereign lord, in opposition to all men, without any saving or exception. Land held by this exalted species of fealty was called feudum legium, a liege fee ; the vassals, homines legii, or liege men; and the 520 ALL ALL Allegiance, sovereign, their dominus legius, or liege lord. And when sovereign princes did homage to each other for lands held under their respective sovereignties, a distinction was al¬ ways made between simple homage, which was only an acknowledgement of tenure, and liege homage, which in¬ cluded the fealty before mentioned, and the services con¬ sequent upon it. In Britain, it becoming a settled principle of tenure that all lands in the kingdom are holden of the king as their sovereign and lord paramount, no oath but that of fealty could ever be taken to inferior lords; and the oath of allegiance was necessarily confined to the per¬ son of the king alone. By an easy analogy, the term of allegiance was soon brought to signify all other engage¬ ments which are due from subjects to their prince, as well as those duties which were simply and merely territorial. And the oath of allegiance, as administered in England for upwards of 600 years, contained a promise “ to be true and faithful to the king and his heirs, and truth and faith to bear of life and limb and terrene honour, and not to know or hear of any ill or damage intended him, with¬ out defending him therefrom.” But, at the Revolution, the terms of this oath being thought perhaps to savour too much of the notion of non-resistance, the present form was introduced by the convention parliament; which is more general and indeterminate than the former, the sub¬ ject only promising “ that he will be faithful and bear true allegiance to the king,” without mentioning “ his heirs,” or specifying in the least wherein that allegiance consists. The oath of supremacy is principally calculated as a renunciation of the pope’s pretended authority; and the oath of abjuration, introduced in the reign of King William, very amply supplies the loose and general tex¬ ture of the oath of allegiance ; it recognising the right of his majesty, derived under the act of settlement engaging to support him to the utmost of the juror’s power, pro¬ mising to disclose all traitorous conspiracies against him, and expressly renouncing any claim on the descendants of the late Pretender, in as clear and explicit terms as the English language can furnish. This oath must be taken by all persons in any office, trust, or employment, and may be tendered by two justices of the peace to any person whom they shall suspect of disaffection; and the oath of allegiance may be tendered to all persons above the age of twelve years, whether natives, denizens, or aliens. But, besides these express engagements, the law also holds that there is an implied, original, and virtual alle¬ giance, owing from every subject to his sovereign, antece¬ dently to any express promise, and although the subject never swore any faith or allegiance in form. Thus, Sir Edward Coke very justly observes that “ all subjects are equally bounden to their allegiance as if they had taken the oath, because it is written by the finger of the law in their hearts, and the taking of the corporal oath is but an outward declaration of the same.” Allegiance, both express and implied, is, however, dis¬ tinguished by the law into two sorts or species, the one natural, the other local; the former being also perpetual, the latter temporary. Natural allegiance is such as is due from all men born within the king s dominions immediately upon their birth ; for immediately upon their birth they are under the king’s protection, at a time, too, when (during their in- fancy) they are incapable of protecting themselves. Na¬ tural allegiance is, therefore, a debt of gratitude, -which cannot be forfeited, cancelled, or altered, by any change of time, place, or circumstance, nor by any thing but the united concurrence of the legislature. A Briton who removes to France or to China, owes the same allegiance to the king of Britain there as at home, and 20 years hence as well as now; for it is a principle of universal Alta law, that the natural-born subject of one prince cannot'-'K by any act of his own, no, not by swearing allegiance to another, put off or discharge his natural allegiance to the former; for this natural allegiance wras intrinsic and pri¬ mitive, and antecedent to the other, and cannot be di¬ vested without the concurrent act of that prince to whom it was first due. Local allegiance is such as is due from an alien, or stranger born, for so long a time as he continues within the king’s dominion and protection; and. it ceases the in¬ stant such stranger transfers himself from this kingdom to another. Natural allegiance is, therefore, perpetual, and local temporary only; and that for this reason, evidently founded upon the nature of government, that allegiance is a debt due from the subject, upon an implied contract with the prince; that so long as the one affords protec¬ tion, so long the other will demean himself faithfully. The oath of allegiance, or rather the allegiance itself, is held to be applicable, not only to the political capacity of the king, or regal office, but to his natural person and blood royal. And, for the misapplication of their alle¬ giance, viz. to the regal capacity or crown, exclusive of the person of the king, were the Spencers banished in the reign of Edward II. And hence arose that principle of personal attachment and affectionate loyalty which in¬ duced our forefathers (and, if occasion required, would doubtless induce their sons) to hazard all that was dear to them, life, fortune, and family, in defence and support of their liege lord and sovereign. It is to be observed, however, in explanation of this al¬ legiance, that it does not preclude resistance to the king, when his misconduct or weakness is such as to make resistance beneficial to the community. It seems fairly presumable, that the convention parliament, which intro¬ duced the oath of allegiance in its present form, did not intend to exclude all resistance ; since the very authority by which the members sat together was itself the effect of a successful opposition to an acknowledged sovereign. Again, the allegiance above described can only be understood to signify obedience to lawful commands. If, therefore, the king should issue a proclamation, levying money or imposing any service or restraint upon the sub¬ ject beyond what the law authorized, there would exist no sort of obligation to obey such a proclamation in con¬ sequence of having taken the oath of allegiance. Neither can allegiance be supposed to extend to the king after he is actually and absolutely deposed, driven into exile, or otherwise rendered incapable, of exercising the regal office. The promise of allegiance implies, that the person to whom the promise is made continues king; that is, continues to exercise the power and afford the protection which belong to the office of king ; for it is the possession of these which makes such a particular person the object of the oath. See Blackstone’s Commentaries, and Paley’s Moral and Political Philosophy. ALLEGORY, in Composition, consists in choosing a secondary subject, having all its properties and circum¬ stances resembling those of the principal subject, and de¬ scribing the former in such a manner as to represent the latter. The principal subject is thus kept out of view, and we are left to discover it by reflection. Nothing gives greater pleasure than an allegory, when the representative subject bears a strong analogy, in all its circumstances, to that which is represented, bat most writers are unlucky in their choice, the analogy being generally so faint and obscure, as rather to puzzle than to please. Allegories, as well as metaphors and similes, are unnatural in expressing any severe passion which totally S’- ALL egri. occupies the mind. For this reason, the following speech UV'"Oof Macbeth is justly condemned by the learned author of the Elements of Criticism : Methought I heard a voice cry, Sleep no more ! Macbeth doth murder Sleep, the innocent sleep; Sleep, that knits up the ravell’d sleeve of care, The birth of each day’s life, sore labour’s bath, Balm of hurt minds, great Nature’s second course, Chief nourisher in life’s feast. Act ii. sc. 2. But see this subject more fully treated under the article Metaphor and Allegory. ALLEGRI, Antonio, called Corregio, from the place of his birth, an eminent historical painter, was bom in the year 1494. Being descended of poor parents, and edu¬ cated in an obscure village, he enjoyed none of those advantages which contributed to form the other great \ painters of that illustrious age. He saw none of the statues of ancient Greece or Rome, nor any of the works of the established schools of Rome and Venice. But Nature was his guide; and Corregio was one of her favourite pupils. To express the facility with which he painted, lie used to say that he always had his thoughts ready at the end of his pencil. The agreeable smile, and the profusion of graces, which he gave to his madonas, saints, and children, have been taxed with being sometimes unnatural; but still they are amiable and seducing. An easy and flowing pencil, a union and harmony of colours, and a perfect intelligence of light and shade, give an astonishing relief to all his pictures, and have been the admiration both of his contem¬ poraries and his successors. Annibal Caracci, who flourish¬ ed 50 years after him, studied and adopted his manner in preference to that of any other master.. In a letter to his cousin Louis, he expressed with great warmth the impres¬ sion which was made on him by the first sight of Corregio’s paintings: “ Every thing which I see here,” says he, “ asto¬ nishes me; particularly the colouring and the beauty of the children. They live, they breathe, they smile with so much grace and so much reality, that it is impossible to refrain from smiling and partaking of their enjoyment. My heart is ready to break with grief when I think on the unhappy fate of poor Corregio—that so wonderful a man (if he ought not rather to be called an angel) should nnish his days so miserably, in a country where his talents were never known J” From want of curiosity or of resolution, or from want of patronage, Corregio never visited Rome, but remained his whole life at Parma, where the art of painting was little esteemed, and of consequence poorly rewarded. This oc¬ currence of unfavourable circumstances occasioned at last his premature death at the age of 40. He was employed to paint the cupola of the cathedral at Parma, the subject of which is the Assumption of the Virgin; and having exe¬ cuted it in a manner that has long been the admiration of every person of good taste, for the grandeur of design, and especially for the boldness of the fore-shortenings (an art which he first and at once brought to the utmost perfec- Oon), he went to receive his payment. The canons of tie church, either through ignorance or baseness, found fault with his work; and although the price originally agreed upon had been very moderate, they alleged that u was far above the merit of the artist, and forced him to accept of the paltry sum of 200 livres; which, to add to me indignity, they paid him in copper money. To carry iome this unworthy load to his indigent wife and children, poor Lorregio had to travel six or eight miles from Parma. e weight of his burden, the heat of the weather, and ' vol rm at v^anous treatment, immediately threw ALL him into a pleurisy, which in three days put an end to his life and his misfortunes. < For the preservation of this magnificent work the world is indebted to Titian. As he passed through Parma, in the suite of Charles V., he ran instantly to see the chef d'ceuvre of Corregio. While he was attentively viewing it, one of the principal canons of the church told him that such a grotesque performance did not merit his notice, and that they intended soon to have the whole defaced. “ Have a care of what you do,” replied the other; “ if I were not Titian, I should certainly wish to be Corregio.” Corregio’s exclamation upon viewing a picture by Raphael is well known. Having long been accustomed to hear the most unbounded applause bestowed on the works of that divine painter, he by degrees became less desirous than afraid of seeing any of them. One, how¬ ever, he at last had occasion to see. He examined it attentively for some minutes in profound silence ; and then with an air of satisfaction exclaimed, I am still a painter. Julio Romano, on seeing some of Corregio’s pictures at Parma, declared they were superior to any thing in paint¬ ing he had yet beheld. One of these, no doubt, was the famous Virgin and Child, with Mary Magdalen and St Jerome; but whether our readers are to depend upon his opinion, or upon that of Lady Millar, who in her Letters from Italy gives a very unfavourable account of it, we shall not presume to determine. This lady, however, speaks in a very different style of the no less famous Notte or Night of Corregio, of which she saw only a copy in the duke’s palace at Modena, the original having been sold for a great sum of money to the king of Poland. “ It surprises me very much,” she says, “ to see how different the characters are in this picture from that which I already have described to you. The subject is a Nativity; and the extraordinary beauty of this picture proceeds from the clair obscure. There are two different lights introdu¬ ced, by means of which the personages are visible ; namely, the light proceeding from the body of the child, and the moonlight. These two are preserved distinct, and pro¬ duce a most wonderful effect. The child’s body is so lu¬ minous, that the superficies is nearly transparent, and the rays of light emitted by it are verified in the effect they produce upon the surrounding objects. They are not rays distinct and separate, like those round the face of a sun that indicates an insurance office; nor linear, like those proceeding from the man in the almanack; but of dazz¬ ling brightness; by their light you see clearly the face, neck, and hands, of the virgin (the rest of the person be¬ ing in strong shadow), the faces of the pastori who crowd round the child, and particularly one woman, who holds her hand before her face, lest her eyes should be so dazz¬ led as to prevent her from beholding the infant. This is a beautiful natural action, and is most ingeniously intro¬ duced. The straw on which the child is laid appears gilt, from the light of his body shining on it. The moon lights up the back ground of the picture, which represents a landscape. Every object is distinct, as in a bright moon¬ light night; and there cannot be two lights in nature more different than those which appear in the same picture. The virgin and the child are of the most perfect beauty. There is a great variety of character in the different per¬ sons present, yet that uniformity common to all herdsmen and peasants. In short, this copy is so admirable, that I was quite sorry to be obliged to lose sight of it so soon; but I never shall forget it. The duke of Modena, for whom Corregio did the original picture, gave him only 600 livres of France for it,—a great sum in those days; but at present what ought it to cost ?” This great painter’s death happened in 1534. 3 u 521 Allegri. 522 ALL ALL Allegri Allegri, Gregorio, an ecclesiastic by profession, and a II celebrated composer of music of the seventeenth century, Allein. wag a native 0f Rome. He was the disciple of Nanini, the ,l"‘^~v^v“intimate friend and contemporary of Palestrina. His abi¬ lities as a singer were not remarkable, but he was deemed an excellent master of harmony; and so much respected by all the musical professors of his time, that the pope, in the year 1629, appointed him to be one of the singers of his chapel. To his uncommon merit as a composer of church music he united an excellent moral character, ex¬ hibiting in his actions the devotion and benevolence of his heart. The poor crowded daily to his door, whom he re¬ lieved to the utmost of his ability; and not content with these beneficent actions, he daily visited the prisons of Rome, in order to relieve the most deserving and afflicted objects which were immured in these dreary mansions. With such divine simplicity and purity of harmony did he compose many parts of the church service, that his loss was severely felt and sincerely lamented by the whole col¬ lege of singers in the papal service. He died on the 18th February 1650, and was interred in the Chiesa Nuova, in a vault destined for the reception of deceased singers in the pope’s chapel, before the chapel of S. Filippo Neri, near the altar of annunciation. Among his other musical works preserved in the ponti¬ fical chapel, is the celebrated Miserere, which, for 170 years, has been annually performed at that chapel on Wednesday and Good Friday, in Passion week, by the choral band, and the best singers in Italy. It is, however, generally believed that it owes its reputation more to the manner in which it is performed, than to the composition itself. The beauty and effect of the music is not discern¬ ible upon paper, but the singers have, by tradition, cer¬ tain customs, expressions, and graces of convention, which produce wonderful effects. Some of the effects produced may be justly attributed to the time, the place, and the solemnity of the ceremonials observed during the per¬ formance. “ The pope and conclave are all prostrated on the ground, the candles of the chapel and the torches of the balustrade are extinguished one by one, and the last verse of this psalm is terminated by two choirs ; the maestro di cappella beating time slower and slower, and the singers diminishing or rather extinguishing the harmony by little and little, to a perfect point.” Padre Martini says, that there was never more than three copies made by autho¬ rity, “ one of which was for the emperor Leopold, one for the late king of Portugal, and the other for himself; but a very complete one was presented by the pope himself to King George III. as an inestimable curiosity.” (Gen. Biog.) ALLEGRO, in Music, an Italian word, denoting that the part is to be played in a sprightly, brisk, lively, and gay manner.

ALLEIN, Joseph, the son of Tobias Allein, was born at Devizes, in Wiltshire, in 1633, and educated at Ox¬ ford. In 1655 he became assistant to Mr Newton, in Taunton Magdalen, in Somersetshire; but was deprived for nonconformity. Fie died in 1668, aged 35. He was a man of great learning, and greater charity; preserving, though a nonconformist, and a severe sufferer on that ac¬ count, great respect for the church, and loyalty to his sovereign. He wrote several books of piety, which are highly esteemed ; but his Alarm to Unconverted Sinners is more famous than the rest. There have been many edi¬ tions of this little pious work, the sale of which has been Al] very great; of the edition 1672 there were 20,000 sold;^ ' of that of 1675, with this title, A Sure Guide to Heaven, 50,000. There was also a large impression of it with its first title in 1720. Allein, Bichard, an English nonconformist divine, a native of Ditchet, in Somersetshire, was born in the year 1611. His father was rector of Ditchet, and conducted the education of his son until he was prepared for the uni¬ versity. There he soon obtained the degree of master of arts; and after he entered into holy orders, first as an as¬ sistant to his father, and afterwards as rector of Batcomb, in Somersetshire, he discharged the duties of a clergyman with great industry and singular fidelity. From his edu¬ cation he conceived an early predilection for the senti¬ ments of the Puritans, and, consequently, in the contest between Charles I. and the parliament he firmly adhered to the latter. Having adopted these sentiments, he sometimes received a little disturbance from the king’s forces ; but he never carried his opposition to any undue length. He, along with several others, signed a paper en¬ titled, “ The testimony of the Ministers of Somersetshire to the truth of Christ,” in which their declared principles and becoming candour were amply displayed. Along with his father, he was employed by the commissioners ap¬ pointed by parliament for ejecting scandalous ministers; a commission which was executed with rigour, and origi¬ nated in intolerance. Upon the Restoration he manifested a disposition to loyalty, but, unable with a good conscience to unite in the act of conformity, he resigned his living after enjoying it for 20 years, and ranked with the meritorious band of sufferers, to the number of 2000, commonly denominated the ejected ministers. In the house of Mr More, who had been a member of the parliament, he exercised the duties of his ministerial office under the penalty of that act, and was consequently reprimanded by the magistrates and im¬ prisoned ; but his piety and exemplary conduct procured him a mitigation of punishment. But no dangers could deter him from duty ; for although constrained to remove from that place in consequence of the “ five-mile act,” he continued in the discharge of his ministerial office at Frome- Selwood. Here he remained until he terminated his la¬ bours by death, in 1681. Piety, boldness, activity, and candour, shone in the character of Richard Allein. He was admired as a pa¬ thetic and practical preacher, and justly respected for the diligence with which he discharged the public and private duties of his profession. Mr Jenkins, the vicar of the parish where he resided, preached his funeral sermon, and bore an honourable testimony to his activity, moderation, and piety. Richard Allein, similar to his nonconformist brethren, chiefly confined his studies and publications to subjects of religion. His works are strongly marked with the peculiar features of the religious character then pre¬ valent among the nonconformists. They have been fre¬ quently reprinted, and very much perused. His most celebrated work is Vindicice Pietatis, or a Vindication of Godliness in its greatest Strictness and Spirituality; with Directions for a Godly Life. This book was published in 1665 without a printer’s name; and being unlicensed, the copies of it were seized and sent to the king’s kitchen for waste paper. The other productions of his pen are, Heaven Opened, or a brief and plain discovery of the riches of God’s Covenant of Grace, printed in 1665; the Wor Conquered, published in 8vo, in 1668; Godly Fear, printed in 8vo, in 1674; a Rebuke to Backsliders, an a Spur for Loiterers, printed in 8vo, in 1677 ; a Companion for Prayer, in 12mo, 1680; a Brief Character of Mr Josepn ALL ALL 523 Aluiah Allein; and Instructions about Heart-work, what is to be the church.

ALLESTRY, Richard, D.D. was born at Upping- ton in Shropshire in 1619, and educated in the grammar school of Coventry, and afterwards at Christ Church in Oxford. His natural talents, which were uncommonly vi¬ gorous, he carefully improved by an unwearied applica¬ tion to study. Accordingly, his promotion was rapid. First he obtained the degree of bachelor of arts ; next he was chosen moderator in philosophy; then made a canon of Christ Church, created doctor of divinity, appointed chaplain in ordinary to the king, and afterwards regius professor of divinity. But in the early part of life his studies were interrupt¬ ed, and he was called to military service by hostile occurrences of the times. In the year 1641 he and many other students of Oxford entered the royal service, and gave eminent proofs of their courage and loyal at¬ tachment. A short interval of hostilities permitted them to return to their literary pursuits ; but a republican par¬ ty soon after disturbed their repose, and entering Oxford, attempted to plunder the colleges. Having entered the treasury, and finding nothing but fourpence and a halter, they hastened to the deanery, and seizing many valuable articles, they locked them in an apartment, intending next day to carry them along with them. During the night, however, Allestry having a key to that apartment, found means to remove the whole of the articles. Informed that he was the cause of their disappointment, they seiz¬ ed him; and had they not been unexpectedly called off by an order of the earl of Essex, they would have se¬ verely wreaked their indignation upon him. In October following he again took up arms, was present at the battle of Keinton-field, and on his way to Oxford to prepare for the reception of the king he was taken prisoner, but soon afterwards released by the king’s forces. A violent disease which then prevailed in the garrison of Oxford brought Allestry to the brink of the grave ; but recovering, he again joined a regiment of volunteers, chiefly consisting of Oxford students. Here he seiwed as a common soldier, and was often seen with the musket in one hand and the book in the other. When the republi¬ can party prevailed, he returned at the termination of the war to his favourite studies, but still continued true to that side of politics which he had adopted. This conduct occasioned his expulsion from the college ; but he was rovided with a comfortable retreat in the families of the onourable Francis Newport and Sir Anthony Cope. Such was the confidence reposed in him, that when the friends of Charles II. were secretly preparing the way for his restoration, they intrusted him with personal messages to the king. In returning from one of these interviews he was seized at Dover, and upon examination committed ALL a prisoner to Lambeth-house. The earl of Shaftesbury Alle obtained his release in a few weeks. Returning to visit his friends, and among others the learned Dr Hammond, A11 he met his corpse at the gate of his house, carrying toV^ the grave. This deeply affected his mind, and added much to his present distresses. The doctor left him his valuable library, assigning as a reason that “ he well knew that his books in his hands would be useful weapons for the defence of that cause he had so vigorously supported.” This valuable library, along with his own, Allestry be¬ queathed at his death to the university. During his life he erected at his own private expense the west side of the outward court of Eton College, the grammar school in Christ Church College, and settled se¬ veral liberal pensions upon individual persons and families. His original biographer gives him the following character. “ Memory, fancy, judgment, elocution, great modesty, and no less assurance, a comprehension of things, and a fluen¬ cy of words ; an aptness for the pleasant, and sufficiency for the rugged parts of knowledge ; a courage to encoun¬ ter and an industry to master all things, make up the cha¬ racter of his happy genius. There was not in the world a man of clearer honesty and courage ; no temptation could bribe him to do a base thing, or terror affright him from the doing a good one. This made his friendship as last¬ ing and inviolable as his life, without the mean considera¬ tions of profit, or sly reserves of craft; without the pa¬ geantry of ceremonious address, the cold civility of some, and the servile falseness and obsequious flattery of others.” He left a volume of sermons, printed at Oxford in 1684, from the perusal of which posterity may judge of his li¬ terary abilities. Although his lectures gave universal sa¬ tisfaction, yet he prohibited their publication. Allestry, Jacob, an English poet of the last century. He was the son of James Allestry, a bookseller of Lon¬ don, who was ruined by the great fire in 1666. Jacob was educated at Westminster School, entered at Christ Church, Oxford, in the act-term 1671, at the age of 18, and was elected student in 1672. He took the degree ot arts ; was music reader in 1679, and terrae-filius in 1681; both which offices he executed with great applause, being esteemed a good philologist and poet. He had a chief hand in the verses and pastorals spoken at the theatre at Oxford, 21st May 1681, by Mr William Saville, second son of the marquis of Halifax, and George Cholmondeley, se¬ cond son of Robert Viscount Kells (both of Christ Church), before James duke of York, his duchess, and the lady Anne ; which verses and pastorals were afterwards print¬ ed in the Examen Poeticum. He died on the 15th Octo¬ ber 1686, and was buried in St Thomas’s churchyard.

From Eton School, in the year 1528, he re¬ moved to King’s College, Cambridge, where he took the degree of bachelor of arts. He also studied some time at Oxford; afterwards he married, was presented with a living, and became a zealous reformer. Upon Queen Mary s ac¬ cession he left his cure and retired into the north of Eng¬ land, where he maintained his wife and himself by teaei- ing a school, and practising physic. Queen Elizabeth as¬ cending the throne, he went to London, where he acquir¬ ed great reputation by reading the divinity lecture at Paul’sj and in July 1560 was consecrated bishop of Exe- ALL . .y ter. He was created doctor of divinity at Oxford in No¬ vember 1561. He died on the 15th of April 1570, and Aiyn. ffas buried at Exeter, in the cathedral. He wrote, 1. The v ^poor Man’s Library, 2 vols. folio, Lond. 1571. These volumes contain twelve lectures on the first epistle of St peter, read at St Paul’s. 2. A Hebrew Grammar. Whe¬ ther it was ever published is uncertain. He translated the Pentateuch, in the version of the Bible which was undertaken by Queen Elizabeth’s command. Alley, in Gardening, a straight parallel walk, bounded on both sides by trees, shrubs, &c. and usually covered with gravel or turf. Alley, in Perspective, that which, in order to have a greater appearance of length, is made wider at the en¬ trance than at the termination. ALLEYN, Edward, a celebrated English actor in the reigns of Queen Elizabeth and King James, and founder of the college of Dulwich in Surrey, was born at London, in tlie parish of St Botolph, on the 1st of September 1566, as appears from a memorandum of his own writing. Dr Fuller says that he was bred a stage-player, and that his father would have given him a liberal education, but that he wras not turned for a serious course of life. He was, however, a youth of an excellent capacity, a cheerful temper, a tena¬ cious memory, a sweet elocution, and in his person of a stately port and aspect; all which advantages might well induce a young man to take to the theatrical profession. By several authorities we find he must have been on the stage some time before 1592; for at that time he was in high favour with the town, and greatly applauded by the best judges, particularly by Ben Jonson. Haywood, in his prologue to Marlow’s Jew of Malta, calls him Proteus for shapes, and Roscius for a tongue. He usually played the capital parts, and was one of the original actors in Shakspeare’s plays; in some of Ben Jonson’s he was also a principal performer: but what characters he personated in any of their plays, it is dif¬ ficult now to determine. This is owing to the inaccu¬ racy of their editors,, who did not print the names of the players opposite to the characters they performed, as the modern custom is ; but gave one general list of actors to the whole set of plays, as in the old folio edition of Shak- speare ; or divided one from the other, setting the drama¬ tis personae before the plays, and the catalogue of per¬ formers after them, as in Jonson’s. It may appear surprising how one of Mr Alleyn’s pro¬ fession should be enabled to erect such an edifice as Dul¬ wich College, and liberally endow it for the maintenance of so many persons. But it must be observed that he had some paternal fortune, which, though small, might lay a foundation for his future affluence ; and it is to be presumed, that the profits he received from acting, to one of his provident and managing disposition, and one who by his excellence in playing drew after him such crowds of spectators, must have considerably improved his for¬ tune : besides, he was not only actor, but master of a play¬ house built at his own expense, by which he is said to have amassed considerable wealth. He was also keeper of the king’s wild beasts, or master of the royal bear-gar¬ den, which was frequented by vast crowds of spectators; and the profits arising from these sports are said to have amounted to L.500 per annum. He was thrice married; and the portions of his first two wives, they leaving him uo issue to inherit, might probably contribute to this benefaction. Such donations have been frequently thought to proceed more from vanity and ostentation than real piety ; but this of Mr Alleyn has been ascribed to a very singular cause, for the devil has been said to be the first promoter of it. Mr Aubrey mentions a tradition, all 525 “A8.1 ?Ir A1Ieyn playing a demon, with six others, in one Aheyn. of Shakspeares plays, was in the midst of the play sur-'^-^v^v^ prised by an apparition of the devil; which so worked on his fancy, that he made a vow, which he performed by building Dulwich College. He began the foundation of this college, under the direction of Inigo Jones, in 161T; and the buildings, gardens, &c. were finished in 1617, in which he is said to have expended about L.10,000. Af¬ ter the college was built, he met with some difficulty in obtaining a charter for settling his lands in mortmain ; for he proposed to endow it with L.800 per annum, for the maintenance of one master, one warden, and four fellows, three whereof were to be clergymen, and the fourth a skilfid organist; also six poor men and as many women, besides twelve poor boys to be educated till the age of fourteen or sixteen, and then put out to some trade or calling. The obstruction he met with arose from the lord chancellor Bacon, who wished King James to settle part of those lands for support of two academical lectures; and he wrote a letter to the marquis of Buckingham, dat¬ ed August 18, 1618, entreating him to use his interest with his majesty for that purpose. Mr Alleyn’s solicitation was, however, at last complied with, and he obtained the royal licence, giving him full power to lay his foundation, by his majesty’s letters patent, bearing date the 21st of June 1619; by virtue whereof he did, in the chapel at the said new hospital at Dulwich, called The College of God s Gift, on the 13th of September following, publicly read and publish a quadripartite writing in parchment, whereby he created and established the said college; he then subscribed it with his name, and fixed his seal to several parts thereof, in presence of several honourable persons, and ordered copies of the writings to four differ¬ ent parishes. He was himself the first master of his col¬ lege ; so that, to make use of the words of Mr Haywood, one of his contemporaries, £ He was so mingled with hu¬ mility and charity, that he became his own pensioner, humbly submitting himself to that proportion of diet and clothes which he had bestowed on others.’ We have no reason to think he ever repented of this distribution of his substance ; but, on the contrary, that he was entirely satisfied, as appears from the following memorial in his own writing, found amongst his papers.—May 26, 1620. My wife and I acknowledged the fine at the common pleas bar, of all our lands to the college : blessed be God that he hath given us life to do it.’ ” His wife died in the year 1623 ; and about two years afterwards he married Con¬ stance Kinchtoe, who survived him, and received remark¬ able proofs of his affection, if at least we may judge of it by his will, in which he left her considerable property. He died on the 25th of November 1626, in the 61st year of his age, and was buried in the chapel. of his new college, where there is a tomb-stone over his grave, with an in¬ scription. His original diary is also there preserved. The subjoining anecdote is entertaining in itself, and shows the high esteem in which Mr Alleyn was held as an actor:—“ Edward Alleyn, the Garrick of Shak¬ speare’s time, had been on the most friendly footing with our poet, as well as Ben Jonson. They used fre¬ quently to spend their evenings together at the sign of the Globe, somewhere near Blackfriars, where the play¬ house then was. The world need not be told, that the convivial hours of such a triumvirate must be pleasing as well as.profitable, and may be said to be such pleasures as might bear the reflections of the morning. In conse¬ quence of one of these meetings, the following letter was written by G. Peele, a student of Christ Church College, Oxford, and a dramatic poet, who belonged to the Club, to one Marie, an intimate of his- ALL 526 ALL Allia' * Friend Marie, .

ALLIANCE, in the Civil and Canon Law, the rela¬ tion contracted between two persons or two families by marriage. Alliance is also used for a treaty entered into by so¬ vereign princes and states, for their mutual safety and defence. In this sense, alliances may be distinguished into such as are offensive, whereby the contracting parties oblige themselves jointly to attack some other power; and into defensive ones, whereby they bind themselves to stand by and defend each other in case they are at¬ tacked by others. The forms or ceremonies of alliances have been various in different ages and countries. An¬ ciently eating and drinking together, chiefly offering sa¬ crifices together, were the customary rite of ratifying an alliance. Among the Jews and Chaldeans, heifers or calves, among the Greeks bulls or goats, and among the Romans hogs, were sacrificed on this occasion. Among the ancient Arabs, alliances were confirmed by drawing blood out of the palms of the hands of the two contract¬ ing princes with a sharp stone, dipping therein a piece of their garments, and therewith smearing seven stones, at the same time invoking the gods Vrotalt and Alilat, i. e. according to Herodotus, Bacchus and Uranius. Among the people of Colchis, the confirmation of alliances was said to be effected by one of the princes offering his wife s breasts to the other to suck, which he was obliged to do till there issued blood. ALLIER, a department of France, on a river of the same name, which runs at the foot of a branch of the Cevennes Mountains. It extends over 365 square leagues, and contains a population of 254,550 persons. It is com¬ posed of a part of the ancient province of Bourbonnois, and of that of Moulins. It is divided into four circles or arrondissements, viz. Mount Lucon, Moulins, Gannat, and Palise. ALLIGATI, in Homan Antiquity, the basest kind of slaves, who were usually kept fettered. The Romans had three degrees or orders of slaves or servants; the first employed in the management of their estates, the second in the menial or lower functions of the family, the third, called alligati, above mentioned. ALLIGATION, the name of a method of solving all questions that relate to the mixture of one ingredient with another. Though writers on arithmetic generally make alligation a branch of that science, yet, as it is plainly nothing more than an application of the common properties of numbers) in order to solve a few questions that occur in particular branches of business, we choose Air rather to keep it distinct from the science of arithmetic. C*- Alligation is generally divided into medial and alternate. Alligation Medial, from the rates and quantities of the simples given, discovers the rate of the mixture. Hule. As the total quantity of the simples, To their price or value; So any quantity of the mixture, To the rate. Example. A grocer mixes 30 lb. of currants, at 4d. per lb. with 10 lb. of other currants, at 6d. per lb.: What is the value of 1 lb. of the mixture ? Ans. 4M. lb. d. d. 30 at 4 amounts to 120 10 at 6 60 40 180 lb. d. lb. d. If40 : 180 :: 1 : 41. Alligation Alternate, being the converse of alligation medial, from the rates of the simples, and rate of the mixture given, finds the quantities of the simples. Rules. I. Place the rate of the mixture on the left side of a brace, as the root; and on the right side of the brace set the rates of the several simples, under one an¬ other, as the branches. II. Link or alligate the branches, so as one greater and another less than the root may be linked or yoked together. III. Set the difference between the root and the several branches right against their re¬ spective yoke-fellows. These alternate differences are the quantities required. Note 1. If any branch happen to have two or more yoke-fellows, the difference between the root and these yoke-fellows must be placed right against the said branch, one after another, and added into one sum. 2. In some questions the branches may be alligated more ways than one; and a question will al¬ ways admit of so many answers as there are different ways of linking the branches. Alligation alternate admits of three varieties, viz. 1. The question may be unlimited, with respect both to the quantity of the simples and that of the mixture. 2. The question may be limited to a certain quantity of one or more of the simples. 3. The question may be li¬ mited to a certain quantity of the mixture. Variety I. When the question is unlimited, with re¬ spect both to the quantity of the simples and that of the mixture, this is called Alligation Simple. Example. A grocer would mix sugars at 5d., 7d., and lOd. per lb., so as to sell the mixture or compound at 8d. per lb.: What quantity of each must he take ? lb. I 2 2 1 | 4. i is placed on the left side of the brace as the root; and on the right side of the same brace are set the rates of the several simples, viz. 5, 7, 10, under one another, as the branches; according to Rule I. The branch 10 being greater than the root, is alligated or linked with 7 and 5, both these being less than the root, as directed in Rule II. The difference between the root 8 and the branch 5, viz. 3, is set right against this branch’s yoke-fellow 10; the difference between 8 and 7 is likewise set right against the yoke-fellow 10; and the difference between 8 and 10, viz. 2, is set right against the two yoke-fellows 7 and 5, as prescribed by Rule III. As the branch 10 has two differences on the right, viz- 3 and 1, they are added; and the answer to the question 8 1S) ^ (loJc s, Here the rate of the mixture f: ALL tion. is, that 2 lb. at 5d., 2 lb. at 7d., and 4 lb. at 10d., will make the mixture required. The truth and reason of the rules will appear by con¬ sidering, that whatever is lost upon any one branch is gained upon its yoke-fellow. Thus, in the above example, by selling 4 lb. of lOd. sugar at 8d. per lb. there is 8d. lost: but the like sum is gained upon its two yoke-fellows ; for by selling 2 lb. of 5d. sugar at 8d. per lb. there is 6d. gained; and by selling 2 lb. of 7d. sugar at 8d. there is 2d. gained; and 6d. and 2d. make 8d. Hence it follows, that the rate of the mixture must al¬ ways be mean or middle with respect to the rates of the simples; that is, it must be less than the greatest, and greater than the least; otherwise a solution would be im¬ possible. And the price of the total quantity mixed, computed at the rate of the mixture, will always be equal to the sum of the prices of the several quantities cast up at the respective rates of the simples. Variety II. When the question is limited to a certain quantity of one or more of the simples, this is called Al¬ ligation Partial. If the quantity of one of the simples only be limited, alligate the branches, and take their dilferences, as if there had been no such limitation; and then work by the following proportion:— As the difference right against the rate of the simple whose quantity is given, To the other differences respectively; So the quantity given, To the several quantities sought. Example. A distiller would, with 40 gallons of brandy at 12s. per gallon, mix rum at 7s. per gallon, and gin at 4s. per gallon: How much of the rum and gin must he take, to sell the mixture at 8s. per gallon ? Galls. ALL 527 8 02^ 1 ,4 40 of brandy, 1 32 of rum, > Ans. 32 of gin. j The operation gives for answer, 5 gallons of brandy, 4 of rum, and 4 of gin. But the question limits the quan¬ tity of brandy to 40 gallons; therefore say, If 5 ; 4 :: 40 : 32. The quantity of gin, by the operation, being also 4, the proportion needs not be repeated. Variety III. When the question is limited to a certain quantity of the mixture, this is called Alligation Total. After linking the branches, and taking the differences, work by the proportion following:— As the sum of the differences, To each particular difference ; So the given total of the mixture, To the respective quantities required. Example. A vintner has wine at 3s. per gallon, and would mix it with water, so as to make a composition of 144 gallons, worth 2s. 6d. per gallon: How much wine, and how much water, must he take ? Galls. 30 J 36 t o \30 / 6 120 of wine 24 of water, a Ans. 36 144 total. 120X36=4320 24 X 0= 0 Proof 144)4320(30 As 36 : 30 :: 144 : 120 As 36 : 6 :: 144 : 24. fhere being here only two simples, and the total of the mixture limited, the question admits but of one answer.

H ALLIO TH, a star in the tail of the Greater Bear, much Allitera- used for finding the latitude at sea. tion* ALLITERATION, an ornament of language chiefly used in poetry, and consisting in the repetition of the same letter at certain intervals. We do not remember to have ever seen any satisfactory account of alliteration in the writings of the critics. They seem to have passed it over in contemptuous silence, either as a false refinement or as a mere trifle. It perhaps deserves a better fate. We apprehend the principal operation of this ornament to be quite mechaniqal. It is easier for the organs of speech to resume, at short intervals, one certain confor¬ mation, than to throw themselves into a number of dif¬ ferent ones, unconnected and discordant. For example, a succession of labials, interspersed at regular distances with dentals and gutturals, will be more easily pronounced than the succession of all the three at random. Sounds of which the articulation is easiest are most completely in the power of the speaker. He can pronounce them slow¬ ly or rapidly, softly or with force, at pleasure. In this, we imagine, the power and advantage of alliteration are found¬ ed ; for we would not lay any stress on the pleasure which can result to the ear from the repetition of the same let¬ ter. It has been compared to the frequent returns of the key-note in a musical strain ; but that analogy is extreme¬ ly faint. The ear, we presume, can be pleased with al¬ literation only in so far as it contributes to the superior easiness of recitation; for what is recited with ease must be heard with pleasure. These remarks might be confirmed and illustrated by numberless passages from the best poets. Some few lines will suffice, taken from Gray, who seems to have paid par¬ ticular attention to this grace. He professed to have learned his versification from Dryden, as Dryden did from Spenser ; and these three abound in alliteration above all the English poets. We choose Gray for another reason, that alliteration contributes not only to the sweetness, but also to the energy, of versification ; for he uses it chiefly when he aims at strength and boldness. In the Sister Odes, as Dr Johnson styles them, almost every strophe commences and concludes with an alliterative line. The poet, we supposed, wished to begin with force, and end writh dignity. “ J?uin seize thee, ruthless king.” “ To /ugh-born //oel’s Aarp, or soft Llewe/Iyn’s /ay.” “ IVeave the warp, and weave the woof.” “ Stamp we our vengeance deep, and ratify his doom.” “ Regardless of the sweeping whirlwind’s sway.” “ That hush’d in grim repose, expects his ev’ning prey.” It must be observed here, that we hold a verse alliterative which has a letter repeated on its accented parts, although those parts do not begin words; the repeated letter bear¬ ing a strong analogy to the bars in a musical phrase. Gray seems to have had a particular liking to those sorts of balanced verses which divide equally, and of which the opposite sides have an alliterative resemblance. “ Eyes that .glow, and fangs that grin.” “ Thoughts that ireathe, and words that /urn.” “ .Hauberk crash, and Aeimet ring.” All these lines appear to us to have a force and energy, arising from alliteration, which renders them easy to be recited ; or, if the reader pleases, mouthed. For the same reason the following passage appears sad and solemn, by the repetition of the labial liquid. “ Mountains, ye mourn in vain.” “ Modred, whose magic song”—&c. 528 ALL ALL Allix If alliteration thus contributes to enforce the expression II of a poetical sentiment, its advantages in poetry must be Alloa, considerable. It is not, therefore, unworthy of a poet’s re- ^>^"gard in the act of composition. If two words offer of equal propriety, the one alliterative, the other not, we think the first ought to be chosen. We would compare this to the practice of fuguing in music. A composer who aims at expression will not hunt after fugues; but if they offer, if they seem to arise spontaneously from the subject, he will not reject them. So a good poet ought not to select an epithet merely for beginning with a certain letter, unless it suit his purpose well in every other respect; for the beauty of alliteration, when happy, is not greater than its deformity when affected. A couplet from Pope will ex¬ emplify both; the first line being bad, and the second good: “ Eternal beauties grace the .shining scene, “ Fields ever/resh, and groves for ever green.” ALLIX, Peter, a French Protestant divine, was born at Alenin in France, in the year 1641. He became a learned divine of the English church, and a strenuous de¬ fender of the Protestant faith. At the time when the edict of Nantes tolerated and protected the Protestants of France, he entered upon his clerical profession, and re¬ mained minister of Rouen until the 35th year of his age. In this period he wrote several pieces upon the controversy between the Papists and the Protestants, which obtained him great fame among his own party. He removed to Charenton in the vicinity of Paris, which was the principal church among the reformed, and frequented by persons of the first rank in France who professed the Protestant faith. Here Allix preached a course of excellent sermons in defence of the Protestant religion, some of which were afterwards printed in Holland, and added to his increasing fame. The chief object of these sermons was to repel the attack of the bishop of Meaux, the most ingenious and able opponent of the Reformation at that time. The un¬ wise revocation of the edict of Nantes drove Allix and many others to seek refuge in England. Three years after his arrival in England, he had made himself so perfectly master of the English language, as to be able to write very correctly a Defence of the Christian Religion. This work he dedicated to James II. in testimony of gratitude for his kind reception of the distressed refugees of France. Not long after his arrival in England he was honoured with the title of doctor of divinity, and also received the more substantial honour of being appointed treasurer of the church of Salisbury. Allix still maintained the station of a champion for the Protestant cause, and in opposition to the bishop of Meaux proved that the charge of heresy justly belonged to the Papists, and not to their opponents, because they had introduced new doctrines into the church. After having with much industry and learning exercis¬ ed his talents in defence of Protestantism, he employed his pen to support the doctrine of the Trinity against the Unitarians, who contended that the idea of Christ’s divi¬ nity could be traced up no higher than the time of Justin Martyr. With a great display of erudition, he attempted to prove that the Trinitarian doctrine wus believed by the Jewish church. But the reputation which he had acquir¬ ed for learning and ability was somewhat diminished, by the ridicule which he brought upon himself in attempting to fix the precise time of Christ’s second coming to the year 1720, or, at the very latest, to the year 1736. He died at London in the year 1717, after his studious life had been protracted to the length of 76 years. ALLOA, a sea-port town of Scotland, in the county of Clackmannan. It is situated on the north shore of the Alii Frith of Forth, 27 miles from Edinburgh, 5 from Stirling by land and 19 by water, 32 from Perth, and 7 from A11( Dollar. It has a safe and commodious harbour, having^ 16 feet of water in neap, and 22 in spring tides. The town is irregularly built. The chief public building is the church, which was first opened in 1819. It is a fine building, in the pointed style of architecture, with a hand¬ some spire. Alloa is noted for the extensive distilleries which are carried on in the neighbourhood, from which large quantities of spirits are shipped for England; also for its breweries, wdiich manufacture great quantities of ale that, for its fine quality, is in repute all over the coun¬ try. Among the principal manufactories of this place are extensive brick and tile works; a copper work, at which are made most of the implements or apparatus for distilleries; the Devon iron works; and a glass work, where, in addition to the ordinary green glass bottles, they now manufacture all sorts of finer glass. There are extensive collieries in the immediate vicinity, from which abundant supplies of fuel are brought by a waggon-way, direct to these works from the mouth of the pit. The exports from Alloa consist of pig-iron, ale, spirits, glass, and coals; and the imports are timber, oak, bark, hides, and great quantities of grain for malting. Adjoining the harbour is an excellent dry dock, capable of receiving ships of the greatest burden ; and to the west is a ferry aci'oss the Forth, which is there 500 yards broad, with piers projecting down to low water-mark. A daily com¬ munication is maintained with Edinburgh and other towns along the Forth by means of steam-boats. It has a custom-house, which comprehends under the port of Alloa the creeks on both sides of the Forth from Kincar¬ dine to Stirling inclusive. In the immediate vicinity of the town there is an ancient tower 89 feet high, with walls 11 feet in thickness, which was built about the year 1315. This was the residence of the Erskines, the de¬ scendants of the Earls of Mar, once a powerful family; and here many of the Scotish princes received their edu¬ cation, having been for more than two centuries the wards of the Lords Erskine and the Earls of Mar. The last heir of the Scotish monarchy educated here was Henry Prince of Wales, whose cradle, golf-clubs, and other memorials were long preserved by the heir of the Earls of Mar. They had also other royal memorials, which were all destroyed in a fire which broke out in the ad¬ joining mansion. Alloa is supplied from the river with water, which is filtered through a circular bed of sand. Population in 1821, 5577. Long. 3. 46. W. Lat. 56. 7. N. ALLOCATION denotes the admitting or allowing of an article of an account, especially in the exchequer. Hence Allocatione Facienda is a writ directed to the lord treasurer, or barons of the exchequer, commanding them to allow an accountant such sums as he has lawfully ex¬ pended in the execution of his office. ALLOCUTIO, an oration or speech of a general ad¬ dressed to his soldiers, to animate them to fight, to ap¬ pease seditidn, or to keep them to their duty. A mount of earth was raised upon the occasion, as it were a kind of a tribunal of turf. From this the general pronounced his harangue to the army, which was ranged in several squadrons around him, with their captains at their head. When the time and circumstances would not admit of a formal harangue, the general went through the ranks, and called each by his name, putting them in mind of their courage upon former occasions, mentioning the victories they had won, and making a promise of plunder. ALLODIUM, or Alleud, denotes lands which are the tion um. A L M A is absolute property of their owner, without being obliged to pay any service or acknowledgement whatever to a supe- Akvst. ,.jor lord. ^ ALLOS, a lake on the top of a lofty mountain in the department of the Lower Alps, in France. It is near the town of the same name, which contains 1400 inhabitants. The lake is about a league in circumference, and abounds in fish, especially in excellent trout. ALLOY, or Allay, properly signifies a proportion of a baser metal mixed with a finer one. The alloy of gold is estimated by carats, that of silver by pennyweights. In different nations different proportions of alloy are used ; whence their moneys are said to be of different degrees of fineness or baseness, and are valued accordingly in foreign exchanges. The chief reasons alleged for the alloying of coin are, 1. The mixture of the metals, which, when smelt¬ ed from the mine, are not perfectly pure ; 2. the saving of the expense it must otherwise cost if they were to be re¬ fined ; 3. the necessity of rendering them harder, by mixing some parts of other metals with them, to prevent the di¬ minution of weight by wearing in passing from hand to hand; 4. the melting of foreign gold or coin which is alloyed; 5. the charges of coinage, which must be made good by the profit arising from the money coined ; 6. and lastly, the duty belonging to the sovereign, on account of the power he has to cause money to be coined in his dominions. ALLSTEDT, a bailiwick in the grand duchy of Saxe- Weimar, containing one city and 12 smaller places, with 5859 inhabitants. A city of 1847 inhabitants, of the same name, is the capital. It is situated on the Rhone, and has a ducal palace. The trade of the place consists in weav¬ ing cloth) and in preparing potash and saltpetre. ALLUM. See Alum. ALLUMINOR, from the French allumer, to lighten, is used for one who coloureth or painteth upon paper or parchment; and the reason is, because he gives light and ornament by his colours to the letters or other figures. Such ornaments are styled illuminations. The word is used in statute 1 Richard III. cap. 9. But now such a person is called a limner. ALLUSION, in Rhetoric, a figure by which something is applied to, or understood of, another, on account of some similitude between them. ALLUVION, in Lato, denotes the gradual increase of land along the sea-shore, or on banks of rivers. ALMACANTARS. See Almucantars. ALMADA,a Portuguese town upon the Tagus, opposite Lisbon, in the province of Estremadura, with 1 monastery, 700 houses, and 3000 inhabitants.

Almadie is also the name of a kind of longboats, fitted u at Calicut, which are 80 feet in length and six or se\en in breadth. They are exceedingly swift, and are lerwise called cdthuri. n-rnat^ers °f literature, is particularly a collection or book composed by Ptolemy, con- A L M taining various problems of the ancients both in eeometrv and astronomy. ° ^ Almagest is also the title of other collections of this , lus’ R'ccioh has published a book of astronomy, which he ca s the New Almagest; and Plukenet, a book which he calls Almagestum Botanicum. ALMAGRA, a fine, deep red ochre, with some admix¬ ture of purple, very heavy, and of a dense yet friable structure, and rough, dusty surface. It adheres very firm¬ ly to the tongue, melts freely and easily in the mouth, is of an austere and strongly astringent taste, and stains the skin in touching. It is the Sil Atticum of the ancients ; it ferments very violently with acid menstruums, by which single quality it is sufficiently distinguished from the Sil Syricum, to which it has in many respects a great affinity. It is found in immense quantities in many parts of Spain* and in Andalusia there are in a manner whole mountains of it. It is used in painting, and in medicine as an astringent. ALMAGRO, a fortress of Spain, the capital of one of the districts of La Mancha. It was built by the arch¬ bishop Roderic of Toledo, who finished it in 1214, and put a considerable garrison into it to restrain the incursions of the Moors. This was hardly done when the fortress was besieged by an army of 5000 horse and foot, under the command of a Moorish officer of great reputation; but die prelate, its founder, took care to supply those5 within with such plenty of necessaries, that at length the enemy found themselves obliged to raise the siege and retire with great loss. Almagro, Diego de, a Spanish commander, was of such obscure birth and mean parentage, that he derived his name from the village where he was born in 1463. Deprived of the means of early instruction, he could neither read nor write; but nevertheless, in consequence of his improvements in the military art, he formed an association with Francisco Pizarro and Hernando de Luque, for the purpose of disco¬ veries and conquest upon the Peruvian coast. The gover¬ nor of Panama having sanctioned their enterprise, they de¬ voted their united exertions to that undertaking. Pizarro directed the conquest, and Almagro was appointed to con¬ duct the supplies of provisions and reinforcements. In the first two unsuccessful attempts, he performed this office with persevering fidelity and uncommon activity. His per¬ severance was followed with complete success; for they at last discovered the coast of Peru, and landed at Tumbez, situated about three degrees south of the line, and dis¬ tinguished by its temple, and a palace of the incas or so¬ vereigns. Pizzaro was sent over to Spain to solicit further powers, after the three adventurers had previously adjust¬ ed their future preferments, and agreed that Pizarro should be governor, Almagro lieutenant-governor, and Luque bishop. In this negotiation Pizarro obtained the clerical dignity for Luque; but, chiefly concerned about his own interest, he neglected the preferment of Ahnagro. On his return, Almagro was so enraged, that he refused to act with such a perfidious companion, and resolved to form a new association. Pizarro for the present artfully endeavoured to avert the indignation of Almagro, and gradually soothed the rage and disappointment of the soldier. The union was renewed upon the former terms ; and it was solemnly stipulated that a common expense and a common advantage should take place. In February 1531, leaving Almagro at Panama to sup¬ ply provisions and reinforcements, Pizarro set sail for Peru. He attacked a principal settlement of the natives in the province of Coaque, obtained immense spoil, and made such ample remittances to Almagro as enabled him to complete his reinforcement; and in the close of the year 1532 Almagro arrived at St Michael with a body of 3 x 530 A L M A L M Almacro. men nearly double the number of those whom Pizarro had along with him. The Spaniards about this time took captive the unfortunate Inca Atahualpa; and after they had received an immense sum for his ransom, they bai - barously put him to death. Ferdinand Pizarro sailed for Spain with the news of their success, and with remittances to a great amount; and consequently Almagro gained that elevated station he had so long and so eagerly desired. But no sooner did he receive the intelligence of his promotion by the royal grant, than he attempted to seize Cuzco, the imperial residence of the incas, under pretence that it lay within his destined territory. This produced a new quar¬ rel ; but peace was restored upon condition that Almagro should attempt the conquest of Chili, and, it he did not find in that province an establishment adequate to Ins merit, that Pizarro should yield up to him a part of Pei u. In 1535 he accordingly set out at the head of 5/0 Europeans, and in crossing the mountains he suffered great hardships and losses by mistaking the route ; but at length he descended into the plains of that devoted^ re¬ gion. Here he met with a more vigorous resistance from the natives than the Spaniards had ever expeiienced in other countries. He had, however, made some progress, when he was recalled to Peru by the news of the natives having risen in great numbers, and attacked Lima and Cuzco. He pursued a new route, and marching through the sandy plains on the coast, he suffered by heat and drought calamities not inferior to those which he had en¬ dured from cold and famine on the summits of the Andes. Arriving at a favourable moment, he resolved to hold the place both against the Indians and his Spanish rivals. He attacked the Peruvian army with great vigour, and mak¬ ing a great slaughter, he proceeded to the gates of Cuzco without any further interruption. The open, affable, and generous temper of Almagro gained over to his side many of the adherents of the Pizarros, who were disgust¬ ed with their harsh and oppressive conduct. With the aid of these he advanced towards the city by night, sur¬ prised the sentinels, and surrounded the house where the two brothers Ferdinand and Gonzalo Pizarro resided, who were compelled, after an obstinate defence, to sur¬ render at discretion. A form of government was settled in the name of Almagro, and his jurisdiction over Cuzco was universally acknowledged. This was the origin of a civil war, the beginning of which was very advantageous to Almagro, who by skilful manoeuvres entirely routed a body of Spanish troops advancing to the relief of Cuzco, and made Alvarado, their commander, prisoner. But in¬ stead of improving these advantages, he unwisely march¬ ed back to Cuzco, and there awaited the arrival of Pizarro, who, convinced of his own feeble resources, proposed an accommodation, and with his usual art protracted the negotiation until he found himself in a condition to meet his antagonist in the field of battle. Meanwhile Alvarado and one of the Pizarros, by bribing their keepers, found means to escape, and persuaded 60 of the men who guard¬ ed them to attend them in their flight; and the gover¬ nor released the other. WTren Pizarro thought himself sufficiently prepared to settle the dominion of Peru, he marched with an army of 500 men to Cuzco. Almagro, previously to this, worn out with age and infirmity, resign¬ ed the command to Orgognez. A fierce and bloody battle ensued, in which Almagro’s army was defeated, and the commander wounded. About 140 soldiers fell in the field, and Orgognez, along with several officers of distinction, was massacred in cold blood. During that fatal day, Almagro, placed in a litter, which was stationed on an eminence, be¬ held from thence the total discomfiture of his troops, and felt all the indignation of a soldier who had seldom expe¬ rienced defeat. He was taken prisoner, remained several Aire ro months in confinement, and was afterwards tried and con-C^ J demned to death. In the view of an ignominious death, the courage of the veteran forsook him, and he unsuccessfully supplicated for life in a manner unworthy of his former character. All the arguments he could employ were in¬ effectual. The Pizarros remained unmoved by all his en¬ treaties. As soon, however, as Almagro saw that his fate was inevitable, he resumed his courage, and exhibited all his usual dignity and fortitude. In the year 1538, and in the 75th year of his age, he was strangled in prison, and afterwards beheaded. He left one son by an Indian woman of Panama; and, in consequence of a power which the em¬ peror had granted him, he declared his son his successor in the government, although he was then a prisoner in Lima. With the qualities of intrepid valour, indefatigable ac¬ tivity, and insurmountable constancy, he blended the more amiable dispositions of frankness, generosity, and candour. These qualities rendered him beloved by his followers, and his misfortunes excited their sympathy and pity ; so that his death was universally regretted, and particularly by the poor Indians, who deemed him their guardian and protector against the cruel and unfeeling Pizarro. Upon the whole review of his character, it ap¬ pears just to conclude, that he was, although of inferior abilities, a more amiable man than his rival. Almagro, the Younger, by his courage, generosity, and other accomplishments, was placed at the head of the party after the death of his father. The father, conscious of his own inferiority from the total want of education, used every possible means to improve the mind and embellish the manners of his son; so that he soon acquired those accomplishments which rendered him respected by illite¬ rate adventurers, who cheerfully ranged round his stand¬ ard, and by his dexterity and skill sought deliverance from the oppressions of Pizarro. Juan de Herrada, an officer of great abilities, continued still to direct his coun¬ cils, and to regulate his enterprises; and, while Pizarro confided in his own security, a conspiracy wa« formed against him, which terminated in his death. The assassins, exulting in their success, and waving their bloody swords, hastened to the street, proclaimed the death of the tyrant, and compelled the magistrates and principal citizens of Lima to acknowledge Almagro as lawful successor of his father. But his reign was of short duration; for, in 1541, Yaca de Castro, arriving at Quito, produced the royal commission, appointing him governor of Peru, together with all the privileges and authority of Pizarro. Ihe ta¬ lents and influence of the new governor soon overpowered the interest of Almagro, who, perceiving the rapid decline of his influence, hastened with his troops to Cuzco, where his opponents had erected the royal standard under t e command of Pedro Alvarez Holguin. Herrada, the gun e of his counsels, died during his march; and from t ia time his measures were conspicuous for their yio ence, concerted with little ingenuity, and executed with i e address. At length, on September 16, 1542, the forces o Almagro and Vaca de Castro met, and victory long re mained doubtful, till at last it declared for the new g vernor. Almagro conducted the military operations that fatal day with a gallant spirit, worthy of a better cause, and deserving of a better fate; and his to o displayed uncommon valour. In proportion to the ® her of combatants the carnage was very great. men, 500 fell in the field, and many more were , i • w snme of ms ed. Almagro escaped, but being betrayed by some o own officers, he was publicly beheaded at ^'uzc0^ 3 me him the name and spirit of the party of Almagro e extinct. A L M A L M 531 ,ra ALMAJORA, a Spanish town on the sea-shore, in I the province of Valencia, with 4500 inhabitants. Lat. Ain®®- 39. 53. N. ALMAMON, or Mamon, also named Abdallah, caliph of Bagdad, was born a. d. 785. His elder brother A1 Amin succeeded to the caliphate on the death of his father, and Almamon at that time was governor of Cho- rasan. As by the will of the father it was provided that his three sons should succeed to the caliphate in order, Almamon ordered his elder brother to be proclaimed caliph throughout his government; but his brother re¬ paid his friendship and attachment to his interest with open expressions of hatred, and unjust attempts to exclude him from the destined succession. Almamon was thus forced to consult measures for his own safety and promo¬ tion, by causing himself to be proclaimed caliph. After various struggles, his general, Thaher, in the year 813, took possession of Bagdad, pursued A1 Amin to his re¬ treat, and caused him to be assassinated, so that Alma¬ mon remained without a competitor. Various rebellions disturbed the tranquillity of the first years of his reign; but, by his prudent administration and vigorous exertions, these were at length extinguished. Instigated by the ad¬ vice of his vizier, he soon after raised greater commotions, and exposed his dignity to greater dangers, by counte¬ nancing the sect of Ali. He invited to court Iman Rizza, gave him his daughter in marriage, and even declared him his successor in the empire. He assumed the green turban, the colour of the house of Ali, and obliged his courtiers and soldiers to imitate his example. Alarmed at these proceedings, the orthodox Mussulmans, and the house of Abbas, excited a great revolt in Bagdad, and proclaimed Ibrahim, Almamon’s uncle, caliph. A civil war was just about to commence, when Fadel the vizier was assassinated, and Rizza died. The people of Bagdad then deposed Ibrahim, and returned to their former alle¬ giance. Taking the advantage of Almamon’s absence, Thaher seized upon the government of Chorasan, where he founded a dynasty which existed during a period of sixteen years. Almamon employed the period of tranquillity that fol¬ lowed, in introducing literature into his dominions, and in its improvement; which constitutes the greatest glory of his reign. During the days of his father he discover¬ ed an ardent thirst after knowledge, by forming a college in Chorasan, adorned with the most eminent men of va¬ rious countries ; and appointed Mesue, a famous Christian physician of Damascus, for their president. When his lather remonstrated against conferring such an honour upon a Christian, he reminded him that the most learn¬ ed men and the most skilful artists in his dominions were Jews and Christians; and added, that he had chosen Mesue as a preceptor in science and useful arts, and not as a teacher of religion. Under his auspices Bagdad be¬ came the seat of literature, of private and academical in¬ struction, and the habitation of men of eminence from all quarters. Many valuable books in the Greek, Persian, Chaldean, and Coptic languages, among which were the works of Aristotle and Galen, were translated into the Arabic at his own expense. This caliph himself deemed U an honour to set an example to others of the becoming respect due to mental cultivation, by visiting the schools, and treating the professors with great regard. In mathe¬ matics, astronomy, and philosophy, he made a rapid and extensive progress. He was the author of astronomical tables, which, on account of their accuracy, have been much admired. By these various exertions the character m the Saracens was suddenly changed from a rude and ferocious to a polite and civilized people, while the most powerful and extensive of the European states were in- Almanack, volved in ignorance and barbarism. Literature has sus-v^^\^^/ tained some irreparable losses from his too great partiality to the Arabic writers, which induced him to destroy the originals of the translated manuscripts. He is represent¬ ed by the Sonnites, or orthodox Mahometans, as little better than an infidel, because of his attention to philoso¬ phy and letters. His conduct, however, shows that he was not sufficiently careful to preserve a philosophical mean between the different religious parties during the time of his administration, as he openly manifested a pre¬ dilection to the doctrines of the Motazeli, who asserted the freewill of man, and denied the eternity of the Ko¬ ran. Some allege that, on account of the murmurs which arose against him, he was induced to exhibit too great a zeal, by establishing a kind of inquisition, to compel all his subjects to profess Islamism. The experiment, how¬ ever, soon terminated in the better and juster expedient of universal toleration ; and it is abundantly evident that the Christians in his dominions never felt the power of his inquisition. The public transactions of his reign are in themselves important. In the year 822 he sent a body of his troops to the assistance of Thomas, a Greek, who made war on Michael the Stammerer, the emperor of Constantinople, and besieged his capital. This expedition, which on the part of the caliph seems to have been founded in justice, proved unsuccessful ; Thomas was taken prisoner, and suffered death. In the years 829 and 830 he commenced hostilities upon the Greeks, rendered himself master of many places, and carried devastation into their territories. He was successful in suppressing a revolt in Egypt in the year 831. In this country he was led to discover a treasure buried under two columns by Merwan, the last caliph of the house of Ommijah. In repairing a decayed mikias or measuring pillar, and erecting a new one for determining the gradation of the increase of the Nile, Almamon display¬ ed his love of science. In the year 833 he again visited Egypt: on his return he penetrated into the territories of the Greek emperor, even into Cilicia. Returning home, he encamped on the banks of a river, and, excited by thirst, drank too freely of the water, and at the same time indulged himself immoderately in eating a particular kind of dates, which brought on a complaint in his stomach, and reduced him to the most imminent danger. Sensible of his approaching dissolution, he sent letters into all the provinces, announcing his brother Motassem his successor, and then patiently awaited the event. Af¬ ter a tedious struggle under the pressure of his disease, and while uttering this ejaculation, “ O thou who never diest, have mercy on me, a dying man !” he expired at the age of 48 or 49 years. He reigned 27 years and some months, and was buried at Tarsus, which some religious zealots interpreted as a mark of reprobation. ALMANACK, a book or table, containing a calendar of days and months, the rising and setting of the sun, the age of the moon, the eclipses of both luminaries, &c.— Authors are divided with regard to the etymology of the word; some deriving it from the Arabic particle al, and manach, to count; some from almanack, new-year’s gifts,^ because the Arabian astrologers used at the beginning ot the year to make presents of their ephemerides; and others from the Teutonic almaen achte, observations on all the months. Dr Johnson derives it from the Arabic particle al, and the Greek /ir\v, a month. But the most simple etymology appears from the common spelling ; the word being composed of two Arabic ones, Al Manack, which signify the Diary. All classes of the Arabs are commonly much given to the study of astronomy and 532 A L M A L M Almanack, astrology; to both of which a pastoral life, and a sort of hus- bandry, not only incline them, but afford time and oppor¬ tunity to cultivate them. They neither sow, reap, plant, travel, buy or sell, nor undertake any expedition or busi¬ ness, without previously consulting the stars, or, in other words, their almanacks, or some of the makers of them. From these people, by their vicinity to Europe, this art, no less useful in one sense than trifling and ridiculous in another, has passed over hither; and those astronomical compositions have still everywhere not only retained their old Arabic name, but were, like theirs, for a long while, and still are among many European nations, interspersed with a great number of astrological rules for planting, sow¬ ing, bleeding, purging, &c. down to the cutting of the hair and paring of the nails. Regiomontanus appears to have been the first in Europe, however, who reduced al¬ manacks into their present form and method, gave the characters of each year and month, foretold the eclipses and other phases, calculated the motions ot the planets, &c. His first almanack was published in 1474. The essential part of an almanack is the calendar of months and days, with the risings and settings of the sun, age of the moon, &c. To these are added lists of posts, offices, dignities, public institutions, with many other articles, political as well as local, and differing in different countries. England has abounded in almanacks, some of them of no very creditable description, though widely circulated among the people for a long period of years. Such, in parti¬ cular, were Moores Almanack, and Poor Robins Almanack, now happily, with several others of the same class, either extinct or about to become so. This change has been mainly owing to the publication of an entirely new al¬ manack by the Society for the Diffusion of Useful Know¬ ledge. The following statement is extracted from a curious article upon English Almanacks, in the London Maga¬ zine, third series, vol. ii. p. 591. “ For a century and a half, the twa universities and the Stationers’ Company held the monopoly of them, by letters patent of James I. During this period, according to the condition of the pa¬ tent, almanacks received the imprimatur of the arch¬ bishop of Canterbury and the bishops of London; and yet it would be difficult to find, in so small a compass, an equal quantity of ignorance, profligacy, and imposture, as was condensed into these publications. By the persever¬ ing exertions of one individual, the monopoly was over¬ thrown about 1779; and the parties claiming the patent- right then applied to parliament for an act to confirm it. That bill was introduced by the minister of the day; but Erskine, then first coming into repute, appeared at the bar to oppose it,—and the monopoly was destroyed for ever, by a solemn vote of the House of Commons. From that time the Stationers’ Company proceeded upon a dif¬ ferent course. They secured their monopoly by buying up all rival almanacks; and they rendered the attempts of individuals to oppose them perfectly hopeless, by those arts of trade which a powerful corporation knew how to exercise. For the last fifty years they have rioted, as of old, in every abomination that could delude the vulgar to the purchase of their commodity. On a sudden a new almanack started up, under the superintendence and authority of a society distinguished for its great and successful labours to improve the intellectual condition of the people. For the first time in the memory of man, an almanack at once rational and popular was produced. From that hour the empire of astrology was at an end. The public press, infinitely to their honour, took up the cause. The blasphemy of Francis Moore, and the ob¬ scenity of Poor Robin, were denounced and ridiculed through all quarters of the kingdom. In one little year Aim' the obscene book was discontinued, the blasphemous book^ retreated into pure stupidity, and the publishers of the Aw blasphemy and the obscenity applied themselves, in imi- ac tation of the first powerful rival they had ever encoun-^ tered, to make a rational and useful almanack.” The al¬ manack of the Society for the Diffusion of Useful Know¬ ledge is entitled the British Almanack; the improved one, published in imitation of it by the Stationers’ Com¬ pany, is called the Englishmans Almanack. The French Almanack Royal is one of the most exten- sive publications of this class, the volume for 1829 ex¬ tending to nearly a thousand octavo pages. Almanack, Nautical. This, which in some respects is a national almanack, is published under the sanction of the Board of Longitude, and is designed chiefly to facilitate the use of Mayer’s Lunar Tables, by supersed¬ ing the necessity of making calculations to determine the longitude at sea. It commenced with the year 1767, and has ever since been continued annually, but two or three years in advance. The late Dr Maskelyne was the origi¬ nator of this very valuable publication. It is now publish¬ ed under the immediate superintendence of the secretary to the Board. Similar to this almanack is the French publication entitled Connoissance des Terns, directed by the Bureau de Longitude, and which commenced so early as the year 1698. Almanacks, among Antiquaries, is also the name given to a kind of instrument, usually of wood, inscribed with various figures and Runic characters, and representing the order of the feasts, dominical letters, days of the week, and golden number, with other matters necessary to be known throughout the year ; used by the ancient northern nations in their computations of time, both civil and ec¬ clesiastical. Almanacks of this kind are known by various names among the different nations in which they have been used, as rimstocks, primstaries, runstocks, runstaffs, Sci- piones Runici, Bacculi Annales, clogs, &c. They appear to have been used only by the Swedes, Danes, and Nor¬ wegians. From the second of these people their use was introduced into England, whence divers remains of them in the counties. Dr Plot has given the description and figure of one of these clogs, found in Staffordshire, under the title of The Perpetual Staffordshire Almanack. The external figure and matter of these calendars appear to have been various. Sometimes they were cut on one or more wooden leaves, bound together after the manner of books ; sometimes on the scabbards of swords, or even daggers; sometimes on tools and implements, as portable steelyards, hammers, the helves of hatchets, flails, &c. Sometimes they were made of brass or horn; sometimes of the skins of eels, which being drawn over a stick pro¬ perly inscribed, retained the impressions of it. But the most usual form was that of walking staves, or sticks, which they carried about with them to church, market, &c. Each of these staves is divided into three regions; whereof the first indicates the signs, the second the days of the week and year, and the third the golden number. The characters engraven on them are, in some, the an¬ cient Runic; in others, the latter Gothic characters of Ulfilas. The saints’ days are expressed in hieroglyphics, significative either of some endowment of the saint, the manner of his martyrdom, or the like. Thus, against the notch for the first of March, or St David s day, is repre¬ sented a harp; against the 25th of October, or Crispin s day, a pair of shoes; against the 10th of August, or ot Lawrence’s day, a gridiron; and, lastly, against New- year’s day, a horn, the symbol of liberal potations, whic our ancestors indulged in at that period. ck A L M 1 . sa ALMANSA, a small city of Murcia, in Spain, to the I north of the river Segura. A pyramid erected near it Alm^or-commemorates the decisive battle fought here in 1707, ^0 French and Spaniards gained a complete victory over the united forces of England and Portugal. It now contains 4000 inhabitants. 15 miles north-north-west of Villena, and 54 south-west of Valencia. ALMANSOR the Victorious, the second caliph of the house of Al Abbas, succeeded his brother Abul Abbas A1 Saffah in the year 753, of the Hegira 136, and in the fol¬ lowing year was inaugurated at Al Hashemiyah. Al¬ though Al Saffah had declared him presumptive heir of the crown, and he had been proclaimed caliph in the im¬ perial city of Anbar, yet immediately upon his inaugura¬ tion his uncle Abdallah ebn Ali had sufficient interest to cause himself to be proclaimed caliph at Damascus. In Arabia, Syria, and Mesopotamia, he collected a numerous army, and arrived at the banks of the Masius, near Nisibis, where he encamped, ready to dispute his royal accession by arms. Almansor collected an immense army in Persia, Chorasan, and Irak, and gave the command of it to Abu Moslem, who harassed his uncle’s troops for five months, and at last totally defeated him, a. d. 754. Notwithstand¬ ing the services which Abu Moslem had rendered to the family of Al Abbas, after this victory he became an object of jealousy, and was assassinated in the presence of Al¬ mansor himself, by his express order. After the death of Abu Moslem, the standard of rebellion was raised by Simon, a Magian, who seized on the treasures of the de¬ ceased governor of Chorasan, and excited the people of that country to a general revolt; but this insurrection was suddenly quelled by the general of Almansor, Jamhur ebn Morad. The caliph avariciously seized the spoils of this victory, which so incensed Jamhur that he imme¬ diately turned his arms against his royal master ; but he was soon defeated by the caliph’s forces. The patriarch of Antioch was about this time detected in an illicit corre¬ spondence with the Grecian emperor, and consequently was banished into an obscure part of Palestine ; and in the mean time the Christians in the dominions of the caliph were prohibited from building or repairing any churches, and also were laid under several other severe restraints. Almansor sent a large army into Cappadocia in the year 757, fortified the city of Malatia or Melitene, and deposited in it a great part of his treasures. But in this year he was attacked by a sect of believers in the metem¬ psychosis, called the Rawandians. This sect assembled at Al Hashemiyah, the residence of the caliph, and, by the ceremony of going in procession round his palace, in¬ timated their purpose of invoking him as a deity, and paying him divine homage. Incensed by their impiety, the caliph ordered several of these sectaries to be impri¬ soned, which roused their resentment, and led them to form the design of his assassination. The generous inter¬ position of Maan ebn Zaidet, an Ommiyan chief, who had been under the necessity of concealing himself from the caliph’s resentment, however, defeated their intention. This insult, received in his capital, induced him to build the city of Bagdad, and to fix his residence there, a. d. ,762. In the preceding year a plan was formed to de¬ throne him ; but it being discovered, he severely punished all who were either directly or indirectly concerned in it. He set out on a pilgrimage to Mecca in the year 774, and being seized on the road with a dangerous disease, he sent for his son and intended successor Al Mohdi, and gave him some salutary advice. “ I command you,” said he, “ to treat publicly your relations with the greatest marks of distinction, since this conduct will reflect no small degree of honour and glory upon yourself. Increase A L M 533 the number of your freedmen, and treat them with all Almaraz kindness, as they will be of great service to you in your II adversity; but neither this nor the other injunction will Alme'- you fulfil. Enlarge not that part of your capital erected on'^~v~v^/ the eastern bank of the Tigris, as you will never be able to finish it; but this work I know you will attempt. Never permit any of your women to intermeddle in affairs of state, or to have any influence over your councils; but this advice I know you will not take. These are my last commands; or, if you please, my dying advice; and to God I now recommend you.” In parting they both gave vent to their feelings in a flood of tears. He pursued his journey to Bir-Maimun, i. e. the well of Maimun, where he died in the 63d year of his age and 20th of his reign. His remains were interred at Mecca. ALMARAZ, a town of Spain, in the province of Old Castile. It is on the north bank of the Tagus, where the road from Badajos divides into two branches, the one pro¬ ceeding towards Madrid, the other towards Plasencia and Ciudad Rodrigo. The destruction of the bridge over the Tagus was one of the most brilliant actions of the late war. ALMARIC, the name of a tenet broached in France by one Almaric, in the year 1209. It consisted in affirm¬ ing that every Christian was actually a member of Christ, and that without this faith no one could be saved. His followers went farther, and affirmed that the power of the Father lasted only during the continuance of the Mosaic law; that the coming of Christ introduced a new law; that at the end of this began the reign of the Holy Ghost; and that now confession and the sacraments were at an end, and that every one is to be saved by the internal operation of the Holy Spirit alone, without any external act of religion. Their morals were as infamous as their doctrine was absurd. Their tenets were condemned by a public decree of the council of Sens, in the year 1209. ALMAZAN, a Spanish town upon the Douro, in the province of Soria. It contains four monasteries, one hos¬ pital, and 2000 inhabitants. ALMAZARRON, a town of Murcia in Spain, on the coast of the Mediterranean. In its vicinity is found a fine red earth without any mixture of sand, called alma- gri, which is very much valued by the polishers of mirrors, and is mixed with all the snuff in the royal manufactory of Seville. This production is supposed by Bowles to be of volcanic origin. ALME, or Alma, singing and dancing girls in Egypt, who, like the Italian Improvisatori, can occasionally pour forth “ unpremeditated verse.” They are called Alme, from having received a better education than other wo¬ men. They form a celebrated society in that country. To be received into it, according to M. Savary, it is ne¬ cessary to have a good voice, to understand the language well, to know the rules of poetry, and be able to compose and sing couplets on the spot, adapted to the circumstan¬ ces. The Alme know by heart all the new songs. Their memory is furnished with the most beautiful tales. There is no festival without them, no entertainment of which they do not constitute the ornament. They are placed in a rostrum, from whence they sing during the repast. They then descend into the saloon, and form dances which have no resemblance to ours. They are pantomime bal¬ lets, in which they represent the usual occurrences of life. The mysteries of love, too, generally furnish them with scenes. The suppleness of their bodies is incon¬ ceivable. One is astonished at the mobility of their fea¬ tures, to which they give at pleasure the impression suit¬ ed to the characters they play. The indecency of their attitudes is often carried to excess. 534 A L M Almehrab The common people have also their Alme. They are li , girls of the second class, who try to imitate the former; Almena. |jU|. they have neither their elegance, their graces, nor their knowledge. They are everywhere to be met with. The public places and the walks about Grand Cairo are full of them. As the populace require allusions still more strongly marked, decency forbids us to relate the licen¬ tiousness of their gestures and attitudes. ALMEHRAB, in the Mahometan customs, a niche in their mosques, pointing towards the kebla or temple of Mecca, to which they are obliged to bow in praying. ALMEIDA, a strong fortress of Portugal, in the pro¬ vince of Beira. It is situated between the rivers Coa and the Duas Casas, which forms a branch of the Agueda. The capture of it by the duke of Wellington, after it had fallen into the hands of the French, was deemed one of the most brilliant exploits of the peninsular war. It is about four leagues from the Spanish fortress of Ciudad Rodrigo. It is well fortified, though till the late war it • was not considered so important as it was then deemed. The Spanish engineers did not estimate it as a defence to Lisbon, but merely covering the province of Beira, into which, according to their judgment, a Spanish army ought never to attempt to penetrate. This place contains 550 houses, 2750 inhabitants, an hospital, one monastery, one church, and a poor-house. ALMEISAR, a celebrated game among the ancient Arabs, performed by a kind of casting of lots with arrows, strictly forbidden by the law of Mahomet, on account of the frequent quarrels occasioned by it. The manner of the game was thus: A young camel being brought and killed, was divided into a number of parts. The adven¬ turers, to the number of eleven, being met, eleven ar¬ rows were provided without heads or feathers; seven of which were marked, the first with one notch, the se¬ cond with two, the third with three, &c.; the other four had no marks. These arrows were put promiscuously into a bag, and thus drawn by an indifferent person. Those to whom the marked arrows fell, won shares in proportion to their lot; the rest, to whom the blanks fell, were en¬ titled to no part of the camel, but obliged to pay the whole price of it. Even the winners tasted not of the flesh themselves more than the losers, but the whole was distributed among the poor. ALMELO, an arrondissement containing six cantons and 57,241 inhabitants, in the province of Overyssel, in the Netherlands. Almelo, a city, the capital of the circle of the same name in Holland. It contains 4662 inhabitants, subsisting chiefly by different branches of the linen manufacture. ALMENE, in Commerce, a weight of two pounds, used to weigh saffron in several parts of the continent of the East Indies. ALMERIA, a city of Spain, in the province of Gra¬ nada, in Andalusia. It is situated on a rocky promontory near Cape de Gat, and from the strength of the port was deemed by the Moorish kings of Granada the most valuable of their fortresses and commercial ports; from whence their cruisers overawed the Catalans and Italians, and the merchants conveyed their various merchandise to Africa, Egypt, and Syria. In its vicinity are found sapphires, cornelians, jaspers, agates, and other precious stones. Near it is the Sierra de Gador, a most enormous mass of marble, whose top rises above the level of the sea to the height of more than 7500 feet, and is covered with snow three quarters of the year. Almeria is the see of a bishop, and has a splendid cathedral. This place contains 7200 inhabitants. There are here manufactories of tar and saltpetre. Long. 1. 44. 54. W. Lat. 36. 51. N. A L M ALMEYDA, Don Francis, was the son of the count Aim d’Abrantes, a grandee of Portugal, who served with great I distinction in the war of Ferdinand of Castile with Gra- nada; and in consequence of his important services he he< became highly esteemed in the court of his sovereign.'^ Without any solicitation on his part he was nominated the first governor-general and viceroy of the newly con¬ quered countries in the East Indies, and set sail from Lis¬ bon in March 1505-6 with a powerful fleet. To give dig¬ nity and influence to his elevated station, a body of guards was appointed to attend his person, several chaplains were assigned to him, together with every other appendage of grandeur. He touched at the Cape Verde islands, doubled the cape at a considerable distance to the south, and ar¬ rived at Guiloa. From thence he proceeded to Mombaza, a well-fortified city in an island, which he reduced, and proceeded to the Angediva islands, not far from Goa, where he built a fort: he likewise erected and garrisoned another fort at Cananore, and arriving at Cochin, he se¬ cured it to the Portuguese interest. The island of Mada¬ gascar was discovered during his government; and his son Don Lorenzo first surveyed the Maidive islands, and about the same time discovered the fine island of Ceylon, the principal sovereign of which he brought under sub¬ mission to the crown of Portugal. Returning from this expedition, while employed in the fleet destined against Calicut, he lost his life in a sea-fight against the Zamorin. His father sustained his loss with an heroic firmness, saying that “ Lorenzo could not die better than in the service of his country.” On the arrival of Alphonso d’Albuquerque, who was destined to be his successor, Almeyda yielded to the impressions of jealousy; and under the pretence of misconduct he confined him in the citadel of Cananore. He engaged in 1508 the whole force of the Mahometans in the port of Diu; and, gaining a complete victory, fa¬ cilitated the enterprises of Albuquerque his successor, by contributing to break that formidable league by which the Zamorin was in hopes of being able to compel the Portu¬ guese to abandon their Indian conquests. Returning home with the great riches which he had acquired, he unfortunately touched at Saldanha Point, on the coast of Africa, where some of the sailors, in quest of water, quar¬ relled with the natives, who attacked and drove them to their ships. With a view to revenge this pretended af¬ front, they persuaded Almeyda himself to go ashore, with a body of 150 men, armed only with swords and lances. While stepping into the boat, Almeyda exclaimed, “ Whi¬ ther do you carry my 60 years ?” The Portuguese fu¬ riously rushed on to attack the natives, whose numbers were greatly augmented; and Almeyda, with fifty-seven of his men, was killed in this rash and unprovoked at¬ tempt. ALMIGGIM. See Almuggim. ALMISSA, a small but strong town at the mouth of the Cetina, in Dalmatia, famous for its piracies; 16 miles east of Spalatro. Long. 18. 14. E. Lat. 43. 56. N. ALMOHEDES, the name of a dynasty, which, in the commencement of the twelfth century, succeeded that of the Almoravides in Barbary. It derived its name from an obscure founder called A1 Mohedi, or A1 Mohedes, and it rose into public notice in the 25th year of the reign of A1 Abraham, or Brahem, who succeeded his father Ali, a. d. 1115. This person was a Bereber, and was a famous preacher of the tribe of Muzamada, which was settled along Mount Atlas. His scheme was formed with in¬ genuity, and executed with unremitting activity. In order to obtain attention and success, he assumed the title of Mohdi or Mohedi, and claimed the honour of leader of the orthodox, or Unitarians; and by his preach- A L M ing they became so numerous, that he even dared to set 3. the royal power at defiance. Confident of security, and ^immersed in pleasure, Brahem looked with a contemptu¬ ous eye upon the insurrection of a party composed of such persons. They increased in number and strength, so that the king was at last roused from his indolence, and prepared for his own security and their subjection. In the first engagement he was defeated, being over¬ powered by superior numbers. The artful Abdallah took possession of the capital, so that Brahem, pursued as a fugitive by Abdolmumen, one of the party, sought re¬ fuge in the city of Fez. The gates were shut against him, but they were opened to admit his pursuers. He next took refuge in the city of Auran, or Oran; but he v/as pursued by Abdolmumen, who threatened to destroy the city with fire and sword; and the magistrates, unable to defend themselves, urged him to leave the town, and pro¬ vide for his own safety. Concealed by the darkness of the night, he escaped with his favourite wife on horse¬ back behind him; but being closely pursued by the ene¬ my, rather than fall into their hands he rushed over a precipice, and, along with his wife, was dashed to pieces. Such was the death of this prince, which put a final period to the empire of the Almoravides. When the death of Brahem was known, Abdolmumen was chosen by the chiefs of that party his successor, and proclaimed king of the Almohedes, under the title of A1 Emir Al Mumin Abdallah Mohammed Abdal Mumin Ebn Ab¬ dallah Ibni Ali, i. e. Chief or Emperor of the true Be¬ lievers of the house of Mohammed Abdal Mumin, the son of Abdal Mumin, the son of Abdallah, of the li¬ neage of Ali. Abdallah, during his reign, enacted pru¬ dential laws for the establishment of his new kingdom, and the regulation of the conduct of his followers. He appointed a council of forty of his disciples, all of whom were preachers. Some of these were commissioned to re¬ gulate all public affairs; and at proper seasons they went forth as itinerant preachers, for the purpose of strengthen¬ ing their party and spreading their doctrines, and sixteen of their number acted as secretaries. As both the regal and pontifical dignities were united in the same per¬ son, the king was chosen from both of these two classes. The disciples of this sect were denominated Mohameddin, or Ali Mohaddin; but the Arabian writers only style them preachers, and the Spanish Al Mohedes. The de¬ scendants and successors of that tribe continued to retain the appellation of Emir Al Mumenin, or chiefs of the faithful believers, as long as their dynasty lasted; and they became very powerful both in Africa and Spain. By their invectives against the tyranny of the Almoravides, and their loud clamours for liberty, they induced the greater part of the kingdom to revolt, and to embrace their religious doctrines. The chief thing in them was their specious pretence to orthodoxy, and strict adherence to the unity of the Godhead, which they inculcated with the greatest zeal and diligence. On his accession to power, the new sovereign extirpat¬ ed all the unhappy remains and steady adherents of this race, by strangling Isaac the son of Brahem. The Almo¬ ravides governor, taking advantage of the general tumult and distraction that prevailed, constituted their govern- aients into independent principalities and petty king¬ doms ; and they who inhabited the mountainous parts established, under their own sheiks, a variety of lordships. The Libyans and Nubians took the lead; and the states of Barbary, Tripoli, Kairwan, Tunis, Algiers, Tremecen, and Bujeiah, followed their example. Abdolmumen, however, successfully pursued his conquests; and in a few years he reduced to his subjection the Numidians A L M 535 and Galatians in the west, and the kingdoms of Tunis, ALmon- Tremecen, and the greater part of Mauritania and Tin- bury gitana. He expelled the Christians of Mohedia, the II chief city of Africa, and some others on the same coast • and likewise made conquests both in Spain and Portugal! He died in the seventh year of his reign, and was suc¬ ceeded, a. d. 1156, by his son Yusef or Joseph. Yusef proved a valiant and martial prince, and in his military court he first established the kings of Tunis and Bujeiah in their respective dominions, as his tributaries and vas¬ sals; and then by earnest solicitation he embarked for Spain to assist the Moorish princes. Yakub or Jacob, or the Conqueror, succeeding him, after providing for his own safety against the revolted and plundering Arabs, pursued his conquests with such success, that he soon became master of the whole country lying between Nu- midia and the entire length of the Barbary coasts, from Tripoli to the boundaries of the kingdom of Morocco ; and thus he was acknowledged as sovereign by most of the Arabian Moorish princes in his Spanish dominions. He also extended his territory above 1200 leagues in length, and 480 in breadth. The remaining part of the history of this prince is involved in obscurity. About the year 1206 he quelled a revolt in Morocco, but violated his faith with the governor of the capital, which he reduced, and in a cruel and perfidious manner extirpated all his adherents. Touched, it is said, with remorse, he disap¬ peared, and, according to report, wandered about obscure and unknown, until he died in the humble condition of a baker at Alexandria. His son Mohammed, surnamed Al Naker, succeeded his father ; and, on his accession to the crown, he passed over into Spain with an immense army of 120,000 horse and 300,000 foot, and engaging the whole force of the Christians on the plains of Tolosa, re¬ ceived a total defeat, with the loss of above 150,000 foot, 30,000 horse, and 50,000 prisoners. According to Spanish and other historians, this fiynous battle was fought in 617, a. d. 1220; but according to the Arabian writers, it was in the year of the Hegira 609, a. d. 1212. Return¬ ing home to Africa, he was received with coldness and disgust by his subjects, on account of his defeat; and soon after died of vexation, having appointed his grandson Zeyed Arrax his successor. A descendant of the Abdol- wates, ancient monarchs of the kingdom, named Gama- razan ebn Zeyen, of the tribe of the Zeneti, caused him to be assassinated. With him terminated the dynasty or government of the Almohedes, having possessed it for about 170 years, which gave place to that of the Beni- merini, another branch of the Zeneti. These having en¬ larged their conquests, and enriched themselves by fre¬ quent inroads, not only into the neighbouring kingdoms, but even into Nubia, Libya, and Numidia, were at length lost in the general prevalence of Mohammedism, after having existed 117 years. ALMONBURY, a township of the wapentake of Ay- brig, in the west riding of the county of York. It is situated on the river Calder, and had formerly a cathedral and a strong castle. It is 186 miles distant from London, in a manufacturing district near Huddersfield. The po¬ pulation in 1801 was 3751; in 1811, 4613; and in 1821, 5679. The whole parish of Almonbury, which includes other townships, contained, in 1821, 23,171 inhabitants. ALMOND, in Commerce, a measure by which the Por¬ tuguese sell their oil: 26 almonds make a pipe. Almonds, in Anatomy, a name sometimes given to two glands, generally called the tonsils. Almonds, among lapidaries, signify pieces of rock- crystal, used in adorning branch-candlesticks, &c., on ac- countof the resemblance they bear to the fruitof that name. 536 A L M Almond Almond Furnace, among refiners, that in which the Furnace slags of litharge, left in refining silver, are reduced to Almorah ^ea(^ aSa'n by the help of charcoal. ALMONER, in its primitive sense, denotes an officer in religious houses, to whom belonged the management and distribution of the alms of the house. By the ancient canons, all monasteries were to spend at least a tenth part of their income in alms to the poor. The almoner of St Paul’s is to dispose of the moneys left for charity, ac¬ cording to the appointment of the donors, to bury the poor who die in the neighbourhood, and to breed up eight boys to singing, for the use of the choir. By an ancient canon, all bishops are required to keep almoners. Lord Almoner, or Lord High Almoner of England, is an ecclesiastical officer, generally a bishop, who has the forfeiture of all deodands, and the goods offelos de se, which he is to distribute among the poor. He has also, by virtue of an ancient custom, the power of giving the first disli from the king’s table to whatever poor person he pleases, or, instead of it, an alms in money. ALMORAH, a small but very curious and interesting town of Hindostan, the modern capital of the province of Kumaon. It is built on a ridge of the Himalaya Moun¬ tains, 5337 feet above the level of the sea, and consists chiefly of a single street, about three fourths of a mile long, and about 50 feet wide, which runs along the ridge of the mountain, with scattered dwellings, chiefly inha¬ bited by Europeans, to the right and left hand on the de¬ scent of the hill. The main street has a gate at each end; and Bishop Heber mentions that it reminded him, on a small scale, of Chester. The houses all stand on a lower story of stone, where the shops are. This is open in front, while the upper stories are faced with a frame¬ work of wood, occasionally carved and painted, supported on the projecting side-walls below, and surmounted by a sloping roof of heavy grey slate, on which many of the inhabitants pile up their hay in small stacks, as winter provender for their cattle. The town is very neat, and the street has a natural pavement of slaty rock, which is kept beautifully clean. It is very strongly situated, and is approached by a long, steep, and winding road, which a handful of men might defend against an army. From Almorah the vast range of the Himalaya Mountains bounds the prospect to the north. Nundidevi, one of the highest peaks in the world, being 25,689 feet above the level of the sea, is within 40 miles from Almorah in a direct line, though it is a nine days’ journey by the only accessible road through the mountains. Almorah was conquered in 1790 by the Ghorkhas, who were favoured by the dissensions of the people. It was taken from them by the British in 1815 ; and in this more recent conquest the inhabitants were also aiding, owing to the cruel treatment they had received from their former mas¬ ters, who were in the habit of selling, for arrears of rent, the wives and children of the peasants into slavery. There is an old Ghorkha citadel, which stands on a com¬ manding point of the ridge, at the eastern extremity ; and several martello towers have been erected in peaks to the eastward. A new citadel, named Fort Moira, has been constructed on a small eminence at the western extremi¬ ty of the town. It is, according to Bishop Heber, very ill contrived, and incapable of defence against a reso¬ lute enemy. The surrounding country is of a bleak and desolate character, and there is scarcely a tree within a circuit of four miles from the walls. The number of houses is about 1000. Almorah is 90 miles north by east froni the city of Bareilly, and about 106 miles tra¬ velling distance north-east from Moradabad, by the route of the Bamoree Pass and Rampour. Long. 79. 44. E. A L M Lat. 29. 35. N. (Heber’s Narrative of a Journey through Aim the Upper Provinces of India, fyc. ; Hamilton’s East In- vid[' dia Gazetteer!) rF\ j ALMORAVIDES, the name of an Arab tribe, who took possession of a district of Africa under the pretence of living in retirement, that their minds might not be dis¬ tracted from the rigid observance of the precepts of the Koran. Hence they assumed the name of Morabites which was changed by the Spaniards into that of Almo- ravides. Abubeker ben Omar, called by the Spanish authors Abu Texefien, was the first chief of this tribe. Supported by a powerful army of malcontents from the pro¬ vinces of Numidia and Libya, which was assembled by the influence of the Morabites or Marabouts, he founded the dynasty of the Almoravides in Barbary, in the year 1051. Texefien was succeeded by his son Yusef or Joseph, who, after having reduced to a state of vassalage the kingdoms of Tremecen, Fez, and Tunis, passed over into Spain du¬ ring the time of the civil wars, vigorously repulsed the Christians, and soon saw the greater part of the king¬ doms of Murcia, Granada, Cordova, Leon, and some parts of Valencia, subjected to his power. He then returned into Africa, and left his newly acquired dominions, with a considerable army, under the government of his nephew Mohammed. On his arrival in Africa, with a view to prosecute and extend his conquest in Spain, he announ¬ ced, in a public declaration, a general gazie, or religious war; assembled a numerous army, with which he em¬ barked at Ceuta; and rejoining his nephew in Andalusia, soon laid waste that province with fire and sword. In the year 1107, five years afterwards, he undertook another invasion, penetrated into the kingdom of Portu¬ gal, and reduced the city of Lisbon, with a considerable part of the kingdom. At this time he lost the cities of Alguazir and Gibraltar, which he had formerly taken. On his return to Barbary he was defeated at sea. This induced him to propose a truce, which was agreed to only on condition of his submitting to become the tributary of the Spanish king. Indignant at these humiliating terms, Yusef made a vow that he would never desist in his at¬ tempts till he had utterly rooted out the Christian religion in Spain. Accordingly he made preparations for a fresh invasion, embarked his army, and landing at Malaga, marched into the enemy’s country. His progress was rapid; but his measures were inconsiderately planned and rashly executed. In the famous battle of the Seven Counts he was indeed victorious, but after a terrible slaughter, and the loss of a great part of his army. This disastrous victory obliged him to return to Africa; and he died soon after at his capital of Morocco. Ali, his son, succeeded to the sovereignty in 1110. This prince, who seems to have been of a less warlike disposition than his father, neglecting his Spanish conquests, turned his attention to the arts of peace, and erected many sumptu¬ ous buildings, and in particular the great mosque of Mo¬ rocco. Alphonso, then king of Arragon, retook from him some considerable cities, which obliged him to undertake an expedition to Spain in support of the Moorish princes. But all his attempts proved unfortunate; and in his last enterprise, though powerfully assisted by the Moorish chiefs, with the loss of 30,000 men he was defeated and slain by Alphonso, in the sixth year of his reign. He was succeeded by his son A1 Abraham, who de¬ voted himself entirely to pleasure. His subjects were harassed and oppressed with heavy taxes, which excited discontent and open rebellion. A revolution was soon effected, and, in the 25th year of his reign, the govern¬ ment was transferred from the tribe of the Almoravides to the Almohedes. See Almohedes. A li M / n3 ALMS, a general term for what is given out of charity to the poor. In the early ages of Christianity, the alms Al me- 0f the charitable were divided into four parts; one of which was allotted to the bishop, another to the priests, ^ and a third to the deacons and subdeacons, which formed their whole means of subsistence; the fourth part was em¬ ployed in relieving the poor, and in repairing the churches. No religious system is more frequent or warm in its exhortations to almsgiving than the Mahometan. The Koran represents alms as a necessary means to make prayer be heard. Hence that saying of one of their ca¬ liphs : “ Prayer carries us half-way to God, fasting brings us to the door of his palace, and alms introduces us into the presence-chamber.” Hence many illustrious examples of this virtue among the Mahometans. Alms also denotes lands or other effects left to churches or religious houses, on condition of praying for the soul of the donor. Hence Free Alms, that which is liable to no rent or service. Reasonable Alms, a certain portion of the estates of in¬ testate persons, allotted to the poor. Alms Box or Chest, a small chest or coffer, called by the Greeks K/Car/ov, wherein anciently the alms were col¬ lected, both at church and at private houses. The alms-chest, in English churches, is a strong box, with a hole in the upper part, having three keys, one to be kept by the parson or curate, the other two by the church-wardens. The erecting of such alms-chest in every church is enjoined by the book of canons, as also the manner of distributing what is thus collected among the poor of the parish. ALMUCANTARS, in Astronomy, an Arabic word, de¬ noting circles of the sphere passing through the centre of the sun or a star, parallel to the horizon, being the same as Parallels of Altitude. Almucantar’s Staff is an instrument usually made of pear-tree or box, having an arch of 15 degrees ; used to take observations of the sun, about the time of its rising and setting, in order to find the amplitude, and conse¬ quently the variation of the compass. ALMUCIUM denotes a kind of cover for the head, worn chiefly by monks and ecclesiastics. It was of a square form, and seems to have given rise to the bonnets of the same shape still retained in universities and cathedrals. ALMUGGIM, Almiggim, or Almug Thee, a certain kind of wood mentioned in the first book of Kings (x. 11), which the Vulgate translates ligna ihyina, and the Sep- tuagint wrought wood. The Rabbins generally render it coral-, others, ebony, brazil, or pine. But it is observed, that the almug tree can by no means be coral, because that is not fit for the purposes for which the Scripture tells us die almug tree was used, such as musical instruments, staircases, &c. The word thyinum is a name for the citron Jme, known to the ancients, and very much esteemed for its sweet odour and great beauty. It came from Mauri¬ tania. The almug tree, or almuggim, or simply gummim, taking al for a kind of article, is therefore, by the best commentators, understood to be an oily and gummy sort of wood, and particularly that sort of tree which pro¬ duces the gum ammoniac, which is also thought to be the same with the shittim wood so frequently mentioned by ALMUNECAR, a small city of the province of Grana- a, in Spain. The soil around it is productive of all the . epical vegetables. Sugar-canes grow as large and as juicy as in the West Indies, the cotton is of excellent quality, and the rum made here is deemed equal to that o Jamaica. The harbour is good, and the entrance well e ended; but during the long war, lately terminated, its A L N principal capital was employed in the productions which Q, nnr-1C,a’ U- peace’ ^sually furnishes to Spain. It contains H00 inhabitants. Long. 3. 54. W. Lat. 36. 42. N. ALNAGE, or Auxnage, the measuring of woollen ma-' nufactures with an ell. It was at first intended as a proof of the goodness of that commodity; and accordingly a seal was invented as a mark that the commodity was made according to statute. ALNAGER, Alneger, or Aulneger, signifies a sworn public officer, who, by himself or deputy, was to look to the assize of woollen cloth made throughout the land, i. e. the length, width, and work thereof; and to the seals for that purpose ordained. The office of king’s al- nager seems to have been derived from the statute of Richard I. a. p. 1197, which ordained that there should be only one weight and one measure throughout the king¬ dom ; and that the custody of the assize or standard of weights and measures should be committed to certain persons in every city and borough. His business was, for a certain fee, to measure all cloths made for sale, till the office was abolished by statute 11 and 12 William III. cap. 20. ALNWICK, a thoroughfare town in Northumberland, on the road to Scotland. Here Malcolm, king of Scot¬ land, making an inroad into Northumberland, was killed, with Edward his son, and his army defeated, by Robert Moubray, earl of this county, anno 1093. Likewise Wil¬ liam, king of Scotland, in 1174, invading England with an army of 80,000 men, was here encountered, his army routed, and himself made prisoner. The town is populous, and in general well built; it has a large town-house, where the quarter-sessions and county-courts are held, and mem¬ bers of parliament elected. It has a spacious square, in which a market is held every Saturday. From the ves¬ tiges of a wall still visible in many parts, and three gates which remain almost entire, Alnwick appears to have been formerly fortified. It is governed by four chamber¬ lains, who are chosen once in two years out of a com¬ mon council, consisting of 24 members. It is ornament¬ ed by a stately old Gothic castle, the seat of the noble family of Percy, earls of Northumberland. As the audits for receipt of rents have ever been in the castle, it has al¬ ways been kept in tolerable repair; and not many years ago it was repaired and beautified by the duke of North¬ umberland, who made very considerable alterations, upon a most elegant plan, with a view to reside in it during a part of the summer season. The manner of making free-r men is peculiar to this place, and indeed is as ridiculous as singular. The persons who are to be made free, or, as the phrase is, leap the well, assemble in the market¬ place, very early in the morning, on the 25th of April, being St Mark's day. They appear on horseback, with every man his sword by his side, dressed in white, and with white nightcaps, attended by the four chamberlains and the castle bailiff, mounted and armed in the same manner. From hence they proceed, with music playing before them, to a large dirty pool called Freemans Well, where they dismount, and draw up in a body, at some dis¬ tance from the water; and then rush into it all at once, and scramble through the mud as fast as they can. As the water is generally very foul, they come out in a dirty condition ; but, taking a dram, they put on dry clothes, re¬ mount their horses, and ride at full gallop round the confines of the district; then re-enter the town, sword in hand, and are met by women dressed in ribbons, with bells and garlands, dancing and singing. They are called timber- wasts. The houses of the hew freemen are on this day distinguished by a great holly bush, as a signal for their friends to assemble and make merry with them after their 3 Y 53? Alnage il .

ALOA, in Grecian Antiquity, a festival kept in honour of Ceres by the husbandmen, and supposed to resemble our harvest-home. ALOGIANS, in Church History, a sect of ancient he¬ retics, who denied that Jesus Christ was the Logos, and consequently rejected the gospel of St John. The word is compounded of the privative a, and J-.oyoi, q. d. without Logos or Word- Some ascribe the origin of the name, as well as of the sect of Alogians, to Theodore of Byzantium, by trade a currier; who having apostatized under the persecution of the emperor Severus, to defend himself against those who reproached him therewith, said, that it was not God he denied, but only man. Whence his fol¬ lowers were called in Greek aXoyoi, because they rejected the Word. But others, with more probability, suppose the name to have been first given them by Epiphanius in the way of reproach. They made their appearance to¬ ward the close of the second century. ALOGOTROPHIA, among physicians, a term signi¬ fying the unequal growth or nourishment of any part of the body, as in the rickets. ALOOF has frequently been mentioned as a sea-term ; but whether justly or not, we shall not presume to deter¬ mine. It is known in common discourse to imply at a dis¬ tance ; and the resemblance of the phrases keep aloof, and keep a luff, or keep the luff, in all probability gave rise to the conjecture. If it was really a sea-phrase originally, it seems to have referred to the dangers of a lee-shore, in which situation the pilot might naturally apply it in the sense commonly understood, viz. keep all off, or quite off : it is, however, never expressed in that manner by seamen now. ALOPECIA, a term used among physicians to denote a total falling off of the hair from certain parts, occasion¬ ed either by the defect of nutritious juice, or by its vi- tious quality corroding the roots of it, and leaving the skin rough and colourless. The word is formed from aXciKrrj?, vulpes, a fox, whose urine, it is said, will oc¬ casion baldness, or because it is a disease which is com¬ mon to that creature. ALOST, a city on the river Dender, between Ghent and Brussels, in the kingdom of the Netherlands. It con¬ tains 12,150 inhabitants, who carry on, by means of the river, a great trade in corn, hops, and beer, and conduct some linen and lace manufactories. Long. 0. 4. E. Lat. 50. 57. N. ALP ARSLAN, the second sultan of the dynasty of Seljuk, in Persia, and great-grandson of Seljuk, the founder of the dynasty. He was born in the year 1030, of the Hegira 421. In place of Israel, which was his original name, he assumed that of Mohammed when he embraced the Mussulman faith; and, on account of his military prow¬ ess, he obtained the surname Alp Arslan, which, in the Turkish language, signifies a valiant lion. Having held the chief command in Chorasan for ten years as lieutenant of his uncle Togrul Beg, he succeeded him in the year 1063, and, at the commencement of his reign, saw himself sole monarch of Persia, from the river Amu to the Tigris. When he assumed the reins of government, faction and open rebellion prevailed in his dominions, in subduing which he was ably assisted by Nadham al Molk, his vizier, one of the most distinguished characters of his time, ALP whose prudence and integrity in the administration of theAlpAi affairs of the kingdom proved of most essential service to'^v this prince and to his successor. Peace and security being established in his dominions, he convoked an assembly of the states; and having declared his son Malek Shah his heir and successor, he seated him on a throne of gold, and exacted an oath of fidelity to him from the principal offi¬ cers of the empire. With the hope of acquiring immense booty in the rich temple of St Basil in Caesarea, the capi¬ tal of Cappadocia, he placed himself at the head of the Turkish cavalry, crossed the Euphrates, and entered and plundered that city. He then marched into Armenia and Georgia, which, in the year 1065, he finally conquer¬ ed. In the former country the very name of a kingdom and the spirit of a nation were totally extinguished; but the native Georgians, who had retired to the woods and valleys of Mount Caucasus, made a more vigorous resist¬ ance. They too, however, overpowered by the arms of the sultan and his son Malek, were forced to submission, and reduced to slavery. To punish them for the brave defence which they had made, and as a badge of their hu¬ miliating condition, Alp Arslan obliged them to wear at their ears horse-shoes of iron. Some, to escape this mark of cruelty and ignominy, professed to embrace the religion of Mahomet. In the year 1068 Alp Arslan invaded the Roman em¬ pire, the seat of which was then at Constantinople. Eu- docia, the reigning empress, saw and dreaded the progress of his arms. To avert the threatened danger, she mar¬ ried Romanus Diogenes, a brave soldier, who was accord¬ ingly associated with her in the government, and raised to the imperial dignity. The new emperor, during the ex¬ hausted state of their resources, sustained the Roman power with surprising valour and invincible courage. His spirit and success animated his soldiers in the field to act with fortitude and firmness, inspired his subjects with hope, and struck terror into his enemies. In three severe campaigns his arms were victorious; and the Turks were forced to retreat beyond the Euphrates. In the fourth he advanced with an army of 100,000 men into the Armenian territory, for the relief of that country. Here he was met by Alp Arslan, with 40,000 cavalry, or, according to some authors, a much smaller number ; and the sultan having proposed terms of peace, which were insultingly rejected by the emperor, a bloody and decisive engagement took place. Alp Arslan, it is said, when he saw that a battle was inevitable, wept at the thought that so many of his faithful followers must fall in the struggle; and alter of¬ fering up a devout prayer, granted free permission to all who chose it to retire from the field. Then with his own hand he tied up his horse’s tail, exchanged his bow and arrows for a mace and scimitar, and robing himself in a white garment perfumed with musk, resolved to perish on the spot unless he came off victorious. The skilful move¬ ments of the Turkish cavalry soon made an impression on the superior numbers of the Greeks, who were thrown into great disorder, and, after a terrible slaughter, were to¬ tally routed. Romanus, deserted by the main body of his army, with unshaken courage kept his station, till he was recognised by a slave, taken prisoner, and conducted into the presence of Alp Arslan. In the T urkish divan t e captive emperor wras commanded to kiss the ground, as a degrading mark of submission to the power and authori V of the sultan, who, it is said, leapt from his throne anc set his foot on his neck. But this is scarcely probab e, o consistent with the generous and respectful trea me which he otherwise experienced; for the sultan mstan > raised him from the ground, embraced him tenderly, an assured him that his life and dignity should remain mv i ALP Aip rslanlate under the protection of a prince who had not forgot- ‘ ten the respect due to the majesty of his equals and the Alpbet. vicissitudes of fortune. When the terms of his ransom ^ ^vvere about to be settled, Romanus was asked by Alp Arslan what treatment he expected to receive. To this question the emperor, with seeming indifference, replied, “ If you are cruel, you will take my life ; if you follow the dictates of pride, you will drag me at your chariot wheels ; if you consult your interest, you will accept a ransom, and restore me to my country.’' “ But what,” says the sultan, “ would you have done in such circumstances ?” “ Had I been victorious,” said the insolent Romanus, “ I would have inflicted on thy body many a stripe.” The conqueror smiled at the fierce and unsubdued spirit of his captive; observed that the Christian precepts strongly inculcated the love of enemies and the forgiveness of in¬ juries ; and, with a noble greatness of mind, declared that he would never imitate an example which he disapproved. A ransom of a million, an annual tribute of 3000 pieces of gold, an intermarriage between the families, and the deli¬ verance of all the captive Mussulmans in the power of the Greeks, were at last agreed to as the terms of peace and the liberty of the emperor. Romanus was now dismissed loaded with presents, and respectfully attended by a mi¬ litary guard. But the distracted state of his dominions, the consequence of a revolt of his subjects, precluded him from fulfilling the terms of the treaty, and remitting the stipulated price of his ransom. The sultan seemed dis¬ posed to favour and support the declining fortunes of his ally; but the defeat, imprisonment, and death of Roma¬ nus interrupted the accomplishment of his generous, or rather ambitious, design. At this time the dominion of Alp Arslan extended over the fairest part of Asia; 1200 princes, or sons of princes, surrounded his throne; and 200,000 soldiers were ready to execute his commands. He now meditated a greater enterprise, and declared his purpose of attempting the conquest of Turkestan, the original seat of his ancestors. After great preparations for the expedition, he marched with a powerful army, and arrived at the banks of the Oxus. Before he could pass the river with safety, it was necessary to gain possession of some fortresses in its vici- ALP 539 Alpha nity, one of which was for several days vigorously de¬ fended by the governor, Joseph Cothual, a Carizmian. II He was, however, obliged to surrender, and was carried a A1phabet prisoner before the sultan, who, being enraged at his ob-^~v^x“ stinacy and presumption, addressed him in very reproach¬ ful terms. Joseph replied with so much spirit, that he roused the resentment of Alp Arslan, and was command¬ ed instantly to be fastened by the hands and feet to four stakes, to suffer a painful and cruel death. Joseph, on hearing this sentence, became furious and desperate ; and drawing a dagger which he had concealed in his boots, rushed towards the throne to stab the sultan. The guards raised their battle-axes, and moved forward to defend their sovereign; but Alp Arslan, the most expert archer of his age, checking their zeal, forbade them to advance, and drew his bow: his foot slipped, and the arrow missed Joseph, who rushed forward, and plunging his dagger in the breast of the sultan, was himself instantly cut in pieces. The wound proved mortal, and the sultan ex¬ pired a few hours after he received it, in the year 1072. ALPHA, the name of the first letter of the Greek al¬ phabet, answering to our A. As a numeral, it stands for one, or the first of any thing. It is particularly used among ancient writers to denote the chief or first man of his class or rank. In this sense the word stands contra¬ distinguished from beta, which denotes the second person. Plato was called the Alpha of the wits. Eratosthenes, keeper of the Alexandrian library, whom some called a Second Plato, is frequently named Beta. Alpha is also used to denote the beginning of any thing; in which sense it stands opposed to omega, which denotes the end. And these two letters were made the symbol of Christianity, and accordingly were engraven on the tombs of the ancient Christians, to distinguish them from those of idolaters. Moralez, a Spanish writer, ima¬ gined that this custom only commenced since the rise of Arianism, and that it was peculiar to the orthodox, who hereby made confession of the eternity of Christ; but there are tombs prior to the age of Constantine whereon the two letters were found, besides that the emperor just mentioned bore them on his labarum before Arius ap¬ peared. ALPHABET. 1l\/rE have received the word Alphabet immediately from ' the Latin, alphabetum, for which substantive, how¬ ever, there is no better authority in that language than the writings of Tertullian and St Jerome. The more classical Juvenal writes, “ Hoe discunt omnes ante alpha et Uta puellce” which is literally, “ girls learn this before their A, B, C.” We do not find the word in Greek. Athenoeus uses the adjective araX^>a/3)jrof to signify a man who does not know the first tw'o letters; and it is from these two letters that our word alphabet is evidently de¬ rived. Whatever the subsequent arrangement may be, the letters A and B stand at the beginning of a great number of alphabets. The ordinary definition of the word is a table or list of characters, which are the signs ot particular sounds. Mathematicians have amused them¬ selves by calculating the number of combinations which way be made of these signs or sounds. Tacquet, accord- lng to Harris, writes thus: “ Mille milliones scriptorum mille annorum millionibus non scribent omnes 24 litterarum olphabeti permutationes, licet singuli qaotidie absolverent 40 paginas, quorum unaqvueque contineret diversos ordines li- terarum 24.” We may doubt, perhaps, whether this pomp of numbers will give any very clear notion even to a mathe¬ matician ; but the passage shows, that for any practical pur¬ pose the combinations of elementary sounds, and conse¬ quently the number of words, may well be considered infi¬ nite. The consideration of the peculiar sets of combina¬ tions which constitute, at least in part, what is called the genius of a language, would be a curious inquiry, that has received but little attention; but it does not belong to this head. It has been asserted that the words of no two lan¬ guages are respectively so unlike as the words in the same language are to themselves, and to one another when read backwards; but this consideration also, of whatever value it be, rather appertains to language itself than to the elements of which it is composed. When we read the volumes of Lord Monboddo on the ori¬ gin of language, we know not whether to laugh more at his countless absurdities and boundless credulity, or to wonder at his ingenuity and learning. Many other works have been composed on the same subject, less ridiculous and less ad¬ mirable, but equally unsuccessful in clearing up the diffi- 540 ALPHABET. Alphabet, culties which they sought to solve. The attempt which is sometimes made to illustrate the invention of writing by that of language, proves invariably to be an impotent ef¬ fort to explain one unknown thing by another. The in¬ vention of alphabetic writing is in truth an inexplicable mystery; we cannot touch it in any way, or approach it on any side. As this opinion is contrary to the common¬ ly received notions, we will briefly state our reasons for adopting it. It is generally believed that certain steps may be ob¬ served, by means of which we are able to trace the gradual progress of the invention. These are the songs and rude drawings of savages, and some simple contriv¬ ances for preserving the memory of numbers by beads and similar devices; but especially the Egyptian hierogly¬ phics, the Chinese characters, and certain alphabets that are said to be syllabic. Learned men have thought fit to assert that there once was a time when no nation was able to write; but they are unable to bring any proof of this assertion, and the evidence of history seems to con¬ tradict it. They tell us that men composed songs and ballads to preserve the remembrance of past events, and used paintings and knots to assist the memory. We know that some nations who are unacquainted with letters use these artifices; and we can readily believe that five beads on a string may represent five men, or five days, or five )rears, but such a memorial has no con¬ nection with writing. We know, moreover, that in times when writing is universal, ballads are made and sung, and paintings are produced; and a person who is unwilling to forget an engagement sometimes ties a knot on his poc¬ ket-handkerchief. Those who can write often avail them¬ selves of other aids ; and those who cannot, have been ob¬ liged in all ages to do as well as they can without. It is manifest that we shall not be able to find any firm ground for placing the first step amongst the operations of sava¬ ges. In common with their civilized brethren, they have the desire to remember certain events ; but they have not done any thing to advance the peculiar means of which we treat. The learned president Goguet, in his instructive and popular work, De l' Origine desLoix, des Arts, et des Sciences, discourses at some length and with much ability of the invention of writing. Having mentioned the substitutes which are adopted by savages, he brings forward the Egyptian hieroglyphics thus : “ We have been a long time in error as to the first use of hieroglyphics : men believed that the Egyptian priests invented them for the purpose of hiding their knowledge from the vulgar, but it is through want of attention that they have been thus deceived. We may easily satisfy ourselves, that at the beginning they only employed hieroglyphics to hand down and make known their laws, their usages, and their history. Nature and necessity, not choice, have produced the different kinds of hieroglyphic writing. It is an im¬ perfect and defective invention, suitable to the igno¬ rance of the first ages: it was through want of the know¬ ledge of letters that the Egyptians had recourse to them. If this nation had found out alphabetic writing before, they would have been too sensible of its advantages to employ any other. The mistake concerning hieroglyphics has come from the Greeks. They were only acquainted with the Egyptians in much later times. This people had then the use of alphabetic characters. The ancient me¬ thod of writing in hieroglyphics had been neglected by the mass of the nation ; but the Egyptian priests, who, ac¬ cording to the custom of all the learned men of antiquity, were only concerned about the means of hiding their learning, retained the hieroglyphic writing as a fit veil Alph to hide the knowledge of what they did not choose to^* divulge. It is thus that, after the discovery of alphabetic writing, hieroglyphics became in Egypt a secret and mysterious kind of writing.” It is plain that a sensible and learned man here speaks too positively about matters which no one can know. If the Greeks, who were ac¬ quainted with the Egyptians, although in later times, are mistaken, how can we, who only know the Egyptians through their report, venture to correct them ? “ But how did they arrive at this discovery ?” The president afterwards candidly asks, “ how did they pass from hiero¬ glyphics, and even from syllabic writing, to alphabetic characters ?” (It would not have been difficult to have pass¬ ed from syllabic writing if it had ever existed.) “ This is not easy to imagine. Hieroglyphics and syllabic writing certainly have no connection with the letters of the alpha¬ bet.” (The latterundoubtedly has, for it represents sounds.) “ It was necessary, then, to change entirely the nature of the signs which were used. In vain shall we have recourse to the writers of antiquity to clear up this question. They do not show us in what manner these singular transitions could have been made. We may conjecture that the abridged marks of hieroglyphic writing, of which I have spoken above, conducted to the still more abridged method of alphabetic letters, which by their different combina¬ tions express all the articulations of the voice in a simple and easy manner. This conjecture becomes very proba¬ ble. When we cast our eyes upon the alphabets of some ancient nations, the letters which compose them appear, both by their forms and their names, to have been taken from hieroglyphic signs. If we compare with attention what remains of the Egyptians with the hieroglyphic figures engraved on the obelisks and other monuments, we shall perceive that the Egyptian letters derive their origin from the hieroglyphics.” “ The Ethiopic alphabet, and the majuscule letters of the Armenians, also supply proofs of wffiat I advance: we find there very distinct traces of the ancient hieroglyphic character.” We know not what he means by “ the ancient Egyptian characters,” unless it be the Coptic alphabet, which is posterior to and derived from the Greek, as Plate XXL demonstrates. It showrs also the Ethiopic letters, and the ordinary Arme¬ nian, which are not ancient: still less are the majuscules or capitals: the latter are undoubtedly formed in the shape of animals, &c.; but they are like the illuminated letters that were used as initials in the middle ages. These certainly were not taken from hieroglyphics, but were designed for ornament; and so is it likewise with the majuscules of the Armenians, which were a very late invention ; and it is matter of history, and not of conjec¬ ture, that they were taught them by the Greeks. It is very doubtful whether the paintings of the Mexicans, of which some writers have treated largely, had any connec¬ tion with writing, or w ere intended for any thing but pic¬ tures ; in truth nothing is known about them, and we may at once dismiss them as having no relation to the subject. The hieroglyphics appear to be related to the alpha¬ bet ; and as they are very extraordinary in themselves, and have received much attention from the learned, we must speak somewhat fully of them; although they will not enable us to trace any transition or progress towards alphabetic writing, which is perfect and complete wher¬ ever it exists, the instances usually adduced of imperfect and incipient writing being in our opinion entirely un¬ founded ; and it is an unwarranted assumption, that the Egyptian hieroglyphics preceded the use of the letters ot the alphabet, of which there is no proof, whatever testi- A L P H ■ | )6ti mony exists being to the contrary. In every generation there have been a few gifted interpreters, who have pro¬ fessed that they were able to read the hieroglyphics; nor have these been wanting in our own times. The expedition of the French to Egypt, and especially the discovery of the famous Rosetta stone, which, the late Dr Young declares, was an ample compensation for all that the two armies suf¬ fered, gave a powerful impulse to these studies. It had been observed on the Egyptian monuments, that clusters of figures were often included in a ring, scroll, or cartouch; and it was deemed expedient that these should represent proper names. To meet the exigency of the case the Phonetic system was devised, which is briefly this: if we suppose that the scroll contains a dog, an ass, and a yew- tree, the initials of the three words are taken, and they form the word Day; and this by the hypothesis is a proper name ; and we may infer, if we please, that Potiphar had read Sandford and Merton, and was greatly delighted with that excellent work. The language, however, in which the objects that supply the initials are to be named, is not English, but Coptic; but the results, we shall see, are pre¬ cisely the same. Let us assume that the figure of a bird denotes A; since the engraving is not executed with the exquisite accuracy of a Bewick, it may be an albatross, a buzzard, a crow, a duck, an eagle—any bird, in short, in the Coptic vocabulary, and any letter in the alphabet; and so with the tree, which stands for B ; it may be an apple, a beech, a cedar, or any arborescent vegetable whatever: and, as if this were not loose enough, each letter has seve¬ ral visible objects, each of which may be made to run the gauntlet of the alphabet. The number of figures contain¬ ed in the scroll, we should have imagined, would control the length of the word, and indicate the number of the letters; but they are relieved from that slight responsibi¬ lity thus: since every allowance ought to be made for a scribe who writes upon granite, IITOAM. will stand for HroAs/ia/os; or, if there be a redundancy of objects, the superfluous letters are disposed of as symbolical, and are classed with the goose and globe, or the goose and grid¬ iron, and some other favourite emblems. Although there be figures enough to complete the name UToki^aiof, that monarch, if it be not his turn, may be desired to stand aside: any three may be chosen to spell Day, and the other seven may be explained symbolically to signify the author of Sandford and Merton, or any thing any body pleases. Such is the Phonetic system, and its-results are such also as might have been expected. Dr Young, an ingenious and learned person, founding himself on certain notions entertained by Warburton, proceeded with singular zeal and activity to compass and imagine dis¬ coveries which we are not able to relate. We will only observe briefly, that any conjecture of that prelate may safely be presumed to be wrong; for although his energy, learning, and acuteness, were undoubtedly great, experi¬ ence has shown, that from haste or some other cause his views are commonly erroneous. Dr Young, being in that vein, of course went on from discovery to discovery, being guided by that warm fancy which usually attends real talent; and, as is ever the case on such occasions, every person who took the pains to investigate the matter found precisely what he was looking for and most desired : no one was ever disappointed. MM. Champollion-Figeac, Syl-> vestre de Sacy, D’Akerblad, and many other foreigners, learned to read,—to run and read. The hieroglyphics were as legible when they rode by the obelisks as the names over our shops. Our own countrymen ran a height career of glory. Mr W. J. Bankes, Mr Salt, and nthers saw immediately strong confirmations. Even Mr ABET. 54i George Grey, a very estimable young gentleman, who Alphabet, took a little trip to Egypt in the season, according to the^-^^'**^ fashion, crept into the great pyramid and out again, saw every thing, bought a charming pair of mummies, a cock and a hen, cut them open, and found, without knowing it, the “ ring of Polycrates,” as Dr Young says, and pei> haps also that of Hans Carvel. He found a Greek translation, it is said, of a manuscript, which had re¬ cently been brought from Egypt to Paris. The origi¬ nal was in the Enchorial character, and the translation showed that it was a sale of land. It was, moreover, duly registered and probably stamped; but that we are not told. That a landowner should go to bed with his title-deeds in his stomach, that the muniments of the de¬ ceased should be buried with him, ought to astonish us, even in an age of discovery. It shows, however, the per¬ fection of the enchorial registration in Egypt, that the settlement was buried with the first tenant for life who died; and it will be a wholesome example to our law- commissioners, who are about to introduce registration in England, and an admonition to make the public title so complete, that all private securities may safely be dispen¬ sed with. The papyrus which Mr George Grey brought from Egypt refers, however, not to the hieroglyphics, but to the characters called enchorial, which are the second in order of the three inscriptions on the Rosetta stone. They seem to be alphabetic, although no one has been able hitherto to make out the alphabet. It is hard indeed to imagine, that there ever was any writing which was not alphabetic. Efforts have been made to interpret these also, but after turning over a few pages of the in¬ terpretation, the reader is disposed to say to the inter¬ preter, “ if you are permitted to read an inscription either backwards or forwards, to consider the letters as imper¬ fectly formed, to select them from any alphabet that will suit your purpose, to turn them round or invert them, to supply, and amend, and reject at pleasure, to take any form of any word in any language you choose, and to make great allowances for barbarism, ignorance, foreign spell¬ ing, and so forth,—if you may do all these things, and cannot find your own name, your mother’s, and mine, in any writing whatever, you certainly are not fit to decipher enchorial characters.” The hieroglyphics which the accom¬ plished Dr Young and his admiring disciples, whether foreign or domestic, were unable to read or to reconcile with their hypotheses, they boldly declared, after the usage of interpreters, to be spurious, and said that they had been negligently and unskilfully sculptured at Rome, in imitation of the Egyptian manner. They speak with as much confidence about a good and a bad style in hieroglyphic inscriptions, as if they were critics writing in the Egyptian Review, if we can fancy that such a periodical existed under the Pharaohs or Ptolemies, and deciding, in a summary manner and without appeal, on the literary merits of the new obelisks and pyramids as they appeared. So intolerant were they of the claims of what Dr Young in his first zeal termed “ an exorbi¬ tant antiquity,” that they condemned as forgeries some of the finest and most admired of the Egyptian monu¬ ments. But such aggressions upon the reverential feel¬ ings of mankind being likely to provoke retaliation, and to endanger the theory, they devised an ingenious ex¬ pedient, and found, under the more modern scrolls, con¬ taining the names of Ptolemies or Roman emperors, the ves¬ tiges of more ancient scrolls comprehending those of older and native princes which had been erased to make way for the usurpers. Some of these, it is said, have been deci¬ phered. And since it has been the fashion to discover the 542 ALPHABET. Alphabet.names of the ancient kings of Egypt, many buildings have been restored to their original rank, and almost every scroll decided to stand in the place of one that had been obliterated. We would recommend some of the most sharp-sighted of these antiquaries to look well if there be not a third and older name under the second, that even “ exorbitant antiquity” may once more be taken into favour. Mr Salt, in his Essay on the Phonetic Sys¬ tem of Hieroglyphics, shows, that even in the symbolical department, which of course must be the most lax, it is necessary to humour the theory a good deal. This zealous convert speaks thus of Horapollo : “ Having so often quot¬ ed this author, I may here state, that though I am con¬ vinced, for numerous reasons, that the first book and part of the second are written by a person perfectly acquainted with Egyptian hieroglyphics, yet so am I perfectly persuad¬ ed that the remainder is a vile interpolation, excepting per¬ haps the three or four last hieroglyphics, which seem to have been reserved from the original work, and placed at the end, more effectually to deceive the reader.” This is very like choosing so much of a writer as will serve a fa¬ vourite purpose, and rejecting the rest. It is unnecessary, however, to pursue this part of the subject farther. If we admit that the discovery of the phonetic system was very admirable ; that it is demonstrated clearly, it may be ma¬ thematically ; that the examples have been adduced with perfect candour and fairness; that it will afford much valuable illustration to the history of Egypt; and that it is madness, or even a crime, to doubt its truth and import¬ ance : if we concede all this, and more, it will not assist us in discovering the origin of the alphabet. The phone¬ tic system is essentially alphabetic; tbe bird, and the tree, and the other figures within the scroll, are not hiero¬ glyphics, but letters : they represent sounds. It is not a transition from hieroglyphics to letters: it is not a step in advance ; but, if it be a step, it is assuredly a step back¬ wards ; for it is merely the substitution of clumsy and ambiguous letters for others that were simple and certain. The dog, the ass, and the yew-tree do not represent the author of Sandford and Merton symbolically or hierogly- phically. That ingenious person had not any of the pro¬ perties peculiar to these objects. The three figures are an awkward manner of writing the three letters that com¬ pose his name, and any other object might be agreed up¬ on to denote the same letters without reference to the initials, which could only have been chosen to assist the memory. A man, a woman, and a child would of course spell Day, if it were understood that a man was in the place of d, and the other figures of the other letters. Thus every one might compose at pleasure innumerable phonetic systems. There is no foundation for the assertion of the pre¬ sident Goguet, and of other learned men, that the Egyp¬ tian hieroglyphics preceded the invention of alphabetic writing: whatever testimony exists is to the contrary. It is vain to argue that it is improbable any persons would use such cumbrous and inconvenient writing af¬ ter they had experienced the advantages of a simple and convenient method ; for there is abundant evidence, as the learned president admits, that it was practised long after they had become acquainted with the ex¬ cellent alphabet of the Greeks. It is not easy to un¬ derstand and to reconcile the passages in which the vari¬ ous sorts of writing that prevailed in Egypt are mention¬ ed; the enchorial, the hieratic, the sacred, the demotic, the Ethiopic, Ac. Our limits will not permit us to comment upon, or even to extract, the statements of Herodotus, Clemens Alexandrinus, Porphyry, Heliodorus, and others. The first author tells us that, unlike the Greeks, they Alp] €t wrote from the right to the left; and Clement and Por-'^-^vO phyry affirm that the hieroglyphics were the invention of the priests, for the purpose of mystery and religious se¬ crecy. Our physicians write their prescriptions in an un¬ couth character, and with barbarous abbreviations, not be¬ cause they are unacquainted with the ordinary writing, but through quackery and for concealment; and for the same reasons the record in a court of law is made up in the form of a carpet, or the sail of a ship; and many similar devices, not unworthy of Tartars or Laplanders, are prac¬ tised there, and in the composition of deeds, not through ignorance, but of design. If the hieroglyphics be in truth writing, and history seems to declare that they are, it is most probable that they are alphabetic ; not only be¬ cause we are told that they were invented when letters were in use, but because it is impossible to conceive any writing which is not such. Whether we shall ever obtain the alphabet, is very doubtful. It is easy to imagine many systems, but it is perhaps impossible to fix upon any. An animal or other object might represent a letter; and the representations might be varied according to fixed rules; or the parts of an animal might be the letters, and the animal itself would then be a word. There is no end of conjectures. It is not impossible, although the supposition has never been hazarded, that the priests wrote in initials only, like the Roman lawyers, who, partly for the sake of brevity, and partly and principally for conceal¬ ment, entered their forms in that manner. A Roman no¬ tary would begin a will thus ; T. I. T. L. W. A. T. &c. “ This is the last will and testament,” &c. Apuleius sup¬ plies a curious passage, which seems to imply that the sacred books were partly secured against profane readers by abbreviations. “ Et injecta dextera senex comissimus ducit me protinus ad ipsas fores aedis amplissimae; rituque solemni apertionis celebrate ministerio, ac matutino per- acto sacrificio, de opertis adyti profert quosdam libros, literis ignorabilibus praenotatos: partim figuris cujusce- modi animalium, concepti sermonis compendiosa verba sug- gerentes ; partim nodosis et in modum rotae tortuosis, ca- preolatimque condensis apicibus, a curiosa profanorum lectione munita.” {Metamorph. lib. 11.) We know not whence the Roman lawyers derived this kind of cipher or abbreviation, of which they made much use. It was a favourite practice likewise of the Rabbins to compose me¬ morial words of initials. We are told that the hieroglyphics were the invention of the priests, and were connected with religion: it is probable therefore that they contain rituals, perhaps in an abbreviated form. The frequent repetitions of the same characters, and the perpetual recurrence of the same sets of characters, favour this supposition. The frequent repetitions of the services of the church of Rome furnished cause of complaint at the Reformation. In the liturgies of the Greek church they are far more remarkable. If we open any book of Greek offices, we shall find such directions as, “ here make 60 kyries, then 30 doxas, then 30 and then 60 more kyries.” The tedi¬ ous ceremonies are infinitely protracted by such wholesale orders. The ancient Egyptians surpassed all people, even the Hindoos, in their addiction to religious exercises. We may read copious details of the prodigious exertions of the early Egyptian monks, who brought, with the com¬ mon zeal of converts, the peculiar sentiments and habits oi their nation, amongst whom all was prayer and rite, every thing was sacred, the whole land swarmed with gods, we could translate a hieroglyphic inscription, we shou probably find that it comprehended the rites to be observ¬ ed in consecrating a punt. It would direct the faithiu A L P H ^ waterman to find the day and hour for the ceremony by certain rules, and to prepare himself and his boat for so many days in such a manner. At the proper hour, hav¬ ing made all previous preparations, he would be enjoined to turn his face to the north, and to say such and such and such prayers so many times, making certain gesticu¬ lations ; and then to turn to the south, and to say the same, and this, that, and another, ten times as often, with the same gestures and some others. It is easy to ima¬ gine that the shortest epitome of the formula, although the boat was not to be used for fishing, or in a part of the Nile where crocodiles abounded, would cover the walls of a building as large as Westminster Hall; for if such folly be once permitted to begin, it is perfectly impossible to assign a reason why it should ever terminate. If such be the treasures which are locked up in the sacred charac¬ ters, as it is most likely they are, we need not repine if we are never permitted to find the key; for it is plain that an authentic and faithful report of the precise words which have been uttered in all the masses that have been said for the repose of the souls of the departed, would be neither an amusing nor an instructive, although a very voluminous, pile of writing. We have shown, we trust, that no assistance can be derived from the hieroglyphics towards discovering the origin of the alphabet. We will next examine, more briefly it is true than we would, the nature of the Chi¬ nese characters, which it is pretended afford much light, and indeed are an infallible guide to the invention of the alphabet. Let us suppose that the tradition as to the sound of the Greek letters, and ah that has been written on the subject, were lost, but that we retained all the other materials for learning Greek which we still possess: if it were deemed expedient to study that di¬ vide language, we might still acquire it with pain and dif¬ ficulty, as we learn the Chinese ; and considering the word aXkiii as a symbol, we should call it another ; ficus, frog, and vqtclims, would be regarded as pictures, and re¬ membered as such; and, without reference to their origi¬ nal sound, would be named many, an ox, life, and a river. In copying these and other words, not as sounds composed of simple elements, but as drawings of objects, they would doubtless be much disfigured in the course of ages; it would even be desirable to vary their forms designedly, and to make them as grotesque and striking as possible, to as¬ sist the memory, which would surely deserve the aid of the compassionate. They would, moreover, be divided into classes, according to some clumsy calculation of the number of strokes by which they are formed, like the Chinese characters, that they might be arranged in dic¬ tionaries. Some mythic story of the invention of the Greek symbols would be current in Europe, as similar fa¬ bles are received in China. The ingenious persons who occupy themselves in finding reasons to account for every thing just as it exists, or is supposed to exist, and lavish their admiration upon it, would indulge in raptures at contemplating the living, moving pictures which these symbols present. Not Cuyp himself, they would declare, could paint such a spirited ox as is sketched out by the image fiou$; and if the sign itoray.cs were drawn large and black, so that the memory might seize on it through the eye and hold it fast, it would be refreshing, they would swear, on a sultry day to sit beside it and gaze on it; for no stream would be so lovely as that gentle Greek river, Qui fluit illimis, nitidis argenteus undis. . ^ Is no light matter to learn Greek now; what would it be under the circumstances we have supposed! When ABET. mankind were at last quite weary of admiring the Greek Alphabet symbols, and of weeping over myriads of schoolboys who had been fairly flogged to death, some great man would at last arise, who, considering that all written language must of necessity be alphabetic, although the alphabet may have been lost in some cases amidst na¬ tional convulsions, would proceed patiently to analyze the characters, not as a logician to seek for genera and species, nor as an artist to look for exquisite touches of art, but simply as a grammarian, to make out the letters. He would carefully dissect a character into parts, and assign arbitrarily to each part its sound, taking due care to make those parts or letters vowels which occur in words in such a manner as to render it necessary or convenient so to consider them for the purpose of articulation. He might, for example, call atCkcs uttak, and mKus gatek ; the harmony of the language would be deteriorated or improved by the change, according to the taste of the age. But when the supposed symbols were once more restored to an alphabe¬ tic form, although entirely different sounds might have been substituted for the ancient, it would not be more dif¬ ficult to acquire the language, than if the original alphabet had never been lost. “ The Chinese characters, taken in general, are, as every body knows, images and symbols, designed to represent directly material objects, by an imitation more or less exact, and other objects by meta¬ phors more or less ingenious. They are consequently entirely unconnected with pronunciation, and do not stand for any sounds. As it is necessary, however, that books should be read aloud, they attach by convention to each character a simple or complex syllable, which brings to the mind, in the spoken language, the same idea as the character in writing; but nothing in the latter denotes the sound or the syllable, and it is very possible to understand the one without knowing the other, and vice versa." We quote these words from the excellent work of M. Abel Ilemusat, entitled Recherches sur les Langues Tartares. M. Freret, who tells the strange tale in his sensible reflections on the Chinese writing, in the sixth volume of the Memoirs of the Academy of Inscriptions, makes this lively remark— “ On diroit que cette ecriture cmroit ete inventee pour des muets, qui ignorent I usage de la parole;" and we may add, that when we believe that the whole population of China are dumb, then will it seem worthy of belief, which is utterly incredible, that any kind of writing was ever de¬ vised that was not alphabetic. A person who gives from a Greek book, without naming the words in the original tongue, a literal translation in English, is like the man who reads aloud Chinese writing in the spoken language of China. He renders one language by another, and of two languages it is possible to know the one and not the other. Some understand English who are ignorant of Greek, and vice versa. “ It was necessary sometimes,” M. Abel Ile¬ musat continues, “ for the Chinese to represent in writing the proper names of persons and of places, and of new objects and ideas. When their knowledge extended, they found that it was impossible to invent figures sufficiently exact, or to compose symbols sufficiently characteristic, to denote, in such a manner that they should be recognised, different natural objects,—quadrupeds, birds, fishes, trees, &c. Many expedients occurred, and were successively em¬ ployed. They might take a symbol which was already known, and make it the sign of an individual. All proper names in China are characters of this sort. Most com¬ monly there is nothing in these characters to mark this kind of alteration. Sometimes, however, they add to the symbol which has been thus stripped of its original mean¬ ing, the sign of the mouth, to show tire change it has 544 ALPHABET. Alphabet, undergone.” The sign of the mouth is precisely equivalent to the use of the capital letter, which with us marks a pro¬ per name, and shows that Mead signifies, not a liquor, but a physician, and Rose a man, and not a flower. Why one man should ever have been called Mead and another Rose, is as much a mystery as any thing in Chinese literature, although the question has not yet provoked an elaborate disquisition concerning the first Mead or the origin of Roses. “ The second method is of so much consequence in Chinese writing, that from the most ancient times it has been accounted one of the six rules for forming characters. It consists in taking, as in the former case, a simple or complex symbol, and adding another, which denotes that it signifies a tree, a bird, . in order to comprehend the sense of the author, let us ca of Hodgkin, and in vol. ix. of the Classical Journal take an example at hazard from the grammar of M. Abel The first column on the left consists of the ordinary Remusat. The following is a literal translation : “ Situt letters, of which the number is increased to 27 by the amat sicut scit aqit earn amat earn earn qui earn qui qui insertion of the Fau ect^/xov, which marks the number 6, non qui non." Could Bishop Wilkins himself detect the after E, of same as in the Hebrew, as the order appears to have and, except perhaps in prosody, grant to it all its rig i ALPHABET. Alp-jjet. By most of the nations of the west it is duly recognised, by the orientals it is usually had in great honour. The Greeks, however, have attenuated it into a spirit, and translated it, as such, out of the alphabet, and ele¬ vated it above the heads of its fellows. The practice of sending letters aloft, that were supposed to have a turn for climbing, exists indeed in many other languages. The two dots or lines, for instance, that sometimes hang over the vowels in the German, are the remains of e: thus pokel was formerly written poekel; and some grammarians have recommended that the old orthography should be resumed. It is unnecessary to multiply examples from other tongues. This letter was anciently marked by the sign H, as in the Latin and our own language. When that sign was applied to denote the »j, it was cut in two, and one half was suspended in the air to mark the spirittcs asper, the rough breathing, or the h, which, according to the definition, is a letter; the other half was hung up in the same manner for a very peculiar purpose, not to de¬ signate any letter, not as the mark of any known sound, but, under the name of the spiritus lenis, it signified the absence of a letter—it became a negative sign in gram¬ matical algebra. Since the spiritus lenis merely imports the absence of the spiritus asper, or h, if a sign be used to show the absence of one letter, there ought equally to be a sign to denote that of every other letter in the alpha¬ bet ; and on this principle there ought to be as many ne¬ gative as positive signs. If it be supposed that the reader who sees the word all cannot understand that the word does not begin with h, and is not hall, unless a spirit tell him so, and a mark be prefixed to signify that the word all does not begin with h, he must need the like assistance to enable him to comprehend that every other letter also is wanting. He ought to be told that the word all does not begin with b, c, d, &c. and that it is not ball, nor call, nor pall, nor tall. Since the initial is not more intelligible than the remainder of the word, every other letter of every word ought on the same principle to be pre¬ ceded by the negative signs of all the letters, to show that it is nothing more than itself. To such absurdities must we be reduced, if we abandon the plain rule, that the ab¬ sence of a letter alone is sufficient to show that it is want¬ ing. We should wonder the more that a people so intel¬ ligent as the Greeks should have fallen into such an error, if, as far as we know, Lanzi had not been the first to no¬ tice it. His reductio ad absurdum of the spiritus lenis has not hitherto received the attention which its acuteness nierits. In Arabic, the mark gesma, unless we look upon it as representing the hyphen, is also a negative sign, im¬ porting, however, a more extensive negation. It has been conjectured that the Greek accentual marks were con¬ trived to assist persons in reading aloud, before the prac¬ tice of leaving a space at the end of each word was adopt¬ ed. They certainly would be extremely useful in this re¬ spect, and they afford great help in perusing a manuscript written continuously. For this purpose the spirits are more useful than the accents; for they show that the vowels oyer which they are placed are initials,—ignorance "hereof is a fertile source of ambiguity; and for this pur¬ pose the spiritus lenis is as necessary as the aspirate. The alter is a letter, and an orthographical mark besides; the ormer is only a mark that the E begins another word, as in nie example KAIEm, which is equivalent to KAI Em, e sign being equal to the space between the two words. It was afterwards usual to place a period after each word, as a spirit general affecting equally vowels and consonants, thus, KAI.Em.AEm; and this expedient is applicable to all words: and many manuscripts that were 547 written continuously have received the convenient addi- Alphabet, turn at a time long subsequent to the date of the writing.' It we consider the spiritus lenis in this point of view the inventors of it will be exculpated from the absurdity of which Lanzi sought to convict them, and it will attach to those grammarians only who retained the mark after the practice of leaving a space at the end of every word be- came pievalent. We must esteem the Greek accents and spirits, especially if we acquiesce in this theory of their in¬ vention, as venerable relics of antiquity—as contrivances which have been superseded. On this account, and from habit, it is difficult for a scholar to consent to abandon them, or to rest satisfied with a work, however well print¬ ed it may be in other respects, in which they are omitted. Orthographical expedients to facilitate reading are nu¬ merous and ingenious, as spaces, punctuation, capitals for proper names and at the beginning of sentences, the apos¬ trophe, and many others. It would be an interesting pur¬ suit to trace their origin and history. Much attention has always been paid to reading and writing by the Chris¬ tians, the Jews, the Mahometans, and, in short, by all na¬ tions whose religion is comprehended in ancient writings. Among the Greeks and Romans, little of their worship had been reduced into writing, nor did they profess to be in possession of a code of divine laws, like the Koran and similar volumes that are studied, transcribed, and vene¬ rated, by the orientals. The reverence that Alexander the Great displayed for the poems of Homer, remarkable as it appeared to his contemporaries, was but a faint sha¬ dow of the homage and adoration that the people of the East lavish on their sacred volumes. The treatment which the Sibylline books received at Rome was perhaps in some respects similar; but they were not publicly read; the grand object, indeed, of those in whose custody they were placed being, although they were not wanting in veneration for the prophetic volumes, to conceal, and not to publish, their mysterious contents. We cheerfully acknowledge that the religion of Greece and Rome, as a political institution, had piany important advantages; but it is not to be denied that it was less favourable to the diffusion of reading and writing than Christianity and some of the religions of the East. The translations of the Scriptures have preserved for the philologer many curious fragments of languages, of which there are no other re¬ mains. In pagan Rome, as in Greece, public recitation and reading aloud were practised to a great extent; but these exercises were always performed by persons of some learning, and of considerable experience, who were com¬ paratively few in number. When the Christians increased, public readers were greatly augmented: it became neces¬ sary to read the Scriptures, homilies, and other pious compositions, not only to learned men in cities, but to the poor and ignorant in the most obscure villages of the most remote provinces; and this office was com¬ monly performed by men of extremely moderate at¬ tainments. It became expedient, therefore, to devise every contrivance that could facilitate the task of reading in public. The Biblical critic knows, that we owe to this cause many orthographical advantages, which are now commonly enjoyed, although the source of them is not generally understood. We are unable, however, to pur¬ sue this part of the subject at present; nor can we find leisure to trace our ordinary running-hand. It may be followed step by step from the Greek cursive, in such works as the Palceographia Grceca, sive de Ortu et Progressu Literarum Grcecarum, of Bern, de Montfau- con; in the curious publication of the Abate Marini, the principal librarian of the Vatican, entitled / Pa- 548 ALPHABET. Alphabet, pin Diplomatid raccolti ed illustrati; in the specimens ‘ 'of D’Agincourt, and in similar publications. The Ara¬ bic alphabet, which, especially in the hands of the Per¬ sians, seems expressly designed to favour rapid writers, has six unconnectible letters; and when the Greek cha¬ racters are written in running-hand, there are several let¬ ters which may not be joined, some with those that pre¬ cede, others with those that follow. In our cux-sive every letter in every word may be united; but as it was first adapted to the Latin language, the school-boy who has written even a theme in that tongue must have remarked that the letters unite more easily and pleasantly than in English. The second plate (No. XX.) presents a comparative table of hieroglyphic and alphabetic characters. We cannot dwell upon this very singular assemblage of signs and symbols, or point out in detail the absurdity of the theories which would deduce alphabetic writing from the Egyptian hieroglyphics ; but it will manifest itself most strikingly and plainly, and without preju¬ dice, to an intelligent person who will examine atten¬ tively this table, which has been arranged expressly for the purpose of presenting an untenable and unfounded hypothesis in the least unfavourable light. The first co¬ lumn on the left, headed “ Chaldaic Letters,” contains an alphabet which is so important in the history of literature, that we must not pass it over without some notice. The Chaldaic or Hebrew alphabet consists of 22 consonants, of which the forms are given on the extreme left of the comparative table, and their powers on the extreme right, and of 14 vowel points, making a total of 36 letters, if we may reckon the points, which are held to be less ancient than the consonants, and are often omitted in manuscripts and printed books, as letters. There are, besides, in a great number, accentual and other marks, designed to facilitate reading, and sometimes perhaps chanting or singing. Of some of these, however, the use is not at present under¬ stood ; our business is with the 22 consonants only, and with their forms. The third letter, g, is called Gimel, which signifies the camel. Camelus suo nomine Syria- co in Latium venit, as Yarro elegantly writes. There can be no doubt about the derivation of the animal’s name, but the letter is as much like any other creature as a camel. Pe, the 17th letter, is called the mouth: it resembles the nose or the eyes equally. And the let¬ ter that immediately precedes it, as its name implies, is thought to be a picture of the eye; but it is as faithful a representation of any other feature, or even of the whole face. The ingenuity of the engraver could not humour the appearance of the teeth so as to make it remind us, as it ought, of the last letter but one—Shin. A very learned Rabbi, from whom we formerly received some instruction in Hebrew, gravely affirmed that the letter Pe, the mouth, is the true image; of that organ; and that if it had not been the Sabbath, he would have written it, and shown, moreover, that there is a piece of pudding in it. Being of¬ fered a dry pen, that he might point it out in a book, he refused to do even that act. Such a severe observance of the day of rest appeared very surprising to persons unac¬ quainted with the strict literal interpretation that pre¬ vails in the East. He consented indeed to explain by words that the piece of pudding is that mark which is inserted in the 17th letter, Pe, and serves to distinguish it from the 11th letter, Caph. The learned Jew, however, did not regard consistency in his explanation, nor do these ingenious people in general; for Caph is the palm of the hand; and by placing a piece of pudding in it, although it would probably be more welcome to the mouth, it would not be made to resemble it in form. Jod, which Alpk L immediately precedes Caph, is the hand also; and these letters are equally unlike the hand and each other. We will not speak longer, however, of this miserable nonsense: the immense load of absurdity would soon become intolerable, if, in passing through several lan¬ guages, we were to pick up in each some new extrava¬ gance. It is true that the names of the greater part, if not all, of the Hebrew letters, signify visible objects; but it does not follow that the letter ever resembled in form the object of which it bears the name. Nouns are used in the second intention without regard to shape; neither the horse for drying clothes, nor the dogs on which wood is burned, nor the cock of a barrel, nor a crow-bar, will re¬ mind us of any of the animals that lend them titles; nor do we ever see a boot-tree or a saddle-tree flourishing, like real trees, with leaves, flowers, and fruit. If we were to teach that our letter B derives its form and name from the insect, and that our alphabet, if considered in the same manner, would furnish a key to the Egyptian hieroglyphics, and would explain the origin of writing, we should not trifle more egregiously than certain expositors of the Hebrew characters. Our third and last plate (No. XXL) comprehends spe¬ cimens of some remarkable alphabets. We will treat them in the order in which they stand. In the Syriac, the number and order of the letters are the same as in the Hebrew, and their names and powers are nearly the same also. The row of characters on the right is that square writing which is called Estranghelo. The letters in the next row are commonly termed Chaldee. Many of them resemble the former, and some are dif¬ ferent. The open letters are the same as the first row, except that they are formed with greater regularity, and are more square. The remaining four columns con¬ sist of the ordinary Syriac letters, varying more or less in form from the Estranghelo, and arranged from the right to the left in order, as initial, medial, final, and solitary letters. Of these alphabets, the Estranghelo is the most ancient and solemn. Some maintain that the Hebrew Scriptures were originally written in this hand. It corre¬ sponds in its origin and use 'with the Roman capitals, which we esteem older than the small letters, and now use only for titles, inscriptions, and the like. The se¬ cond column, or Chaldee, is called also the reformed Syriac, being a medium between the Estranghelo and the ordinary Syriac. Vowel points are added to these letters; but it is acknowledged that the use of them, in this lan¬ guage at least, is entirely modern. The Illyrian and Ser¬ vian alphabets are evidently derived from the Greek: Grceco fonte cad ant; we cannot add, however, parce detorta: the order of the letters is the same, many being inserted. The two rows of letters on the left, which are usually very like the Greek originals, are the Servian, and are commonly called the alphabet of St Cyril, being ascribed to that saint. The other two rows of letters, which are, as it were, double, and frequently of an extra¬ ordinary form, are the Illyrian, or Dalmatian, and are named the alphabet of St Jerome. We are apt to wonder why the good father should have taken so much trouble, if he was indeed the inventor, to disfigure the elements o speech. The appearance of the Illyrian, when we see an entire passage in this character, is still more strange: it's impossible indeed to judge of its effect from a mere tab e of letters. We regret, therefore, that our space will no suffer us to give a specimen of this whimsical and unusua writing. The Russian alphabets, both ancient and mo dem, are formed from the Greek by additions and altera A L P H 1 lbet. t;ons, the order of the letters being nearly the same. The v Ethiopia alphabet, which occupies the middle of the plate, is extremely interesting, because it is said to be a great and important step in the history of writing; and it is ex¬ pressly referred to by the very learned President Goguet, as a specimen of a syllabic alphabet: “ rectius syllaba- rium quam alphabetum.” Syllabic writing, if it ever exist¬ ed, would not be a step from hieroglyphic to alphabetic writing: it would be a kind of alphabetic writing, in which the alphabet would be very numerous, and the sounds expressed by each letter complex; but it would have no connection with hieroglyphics; the pretended link would be united to the chain at one end, but not at the other. If we suppose prosterner, the word chosen by Goguet, to be represented by three letters only, each of which is a syllable, as otV, the w, which stands for pro, would mark a complex sound, but it would not be in any respect hiero¬ glyphic. It would not denote a sensible object or an idea, and so of the other two syllabic letters a and v, and of all the rest. The conjecture would appear probable in itself, that syllabic characters are compounded of other and less complex forms ; nor is the aspect of the alphabets that are put forth as belonging to this class so simple as to exclude the supposition. It is easy in the Ethiopia to trace the vowel which is added with tolerable uniformity to the simple let¬ ter. There are a few anomalies, no doubt, as in the gram¬ matical arrangements of all languages. The first column on the left, next to the name, shows the simple letter. It is not combined with the vowel a, as it would seem at first sight; for that union is effected in the fourth or middle column. A moment’s inspection of this alphabet and table of syl¬ lables will satisfy any one that it is composed of 26 con¬ sonants—we must use the word in an eastern sense—com¬ bined with six vowels, preciselyr like the tables ba, be, bi, bo, bu, by, &c., in our spelling-books; and that it does not in any respect resemble the case which is put by Go¬ guet, of the word prosterner being spelled by three letters. As the Sanscrit alphabet is not shown on our plates, we will not analyze it to prove that it is not to be considered as syllabic. The Persian is as much entitled to that ap¬ pellation, because the junction of the letters being often difficult, they write, for the assistance of learners, books full of syllables. It is not by steps built of such mate¬ rials as these that we can hope to ascend to the origin of that most wonderful invention, the alphabet. The Ethio- pic is derived from the Arabic: it is a dead language, like the Latin, and it is called the language of study, or the language of books: the Abyssinian, or Amharic, so called from Amhar, the principal province of Abyssinia, and termed the royal language, has taken its place as a living speech; and seven letters have been added to the 26 of the Ethiopic alphabet, which we have given. These two languages may be studied in the grammars of Job Ludol- phus, who tells us that they are of difficult acquisition, and declares the words to be exceedingly unutterable— “ maxime esse ineffabilia.” The aspect of the characters, when arranged in words and sentences, is uncouth and unsightly: they somewhat resemble the Tironian notes, which, although their appearance is unpromising, were written, as we are informed by positive testimony, with great rapidity. Contractions, abbreviations, and connec¬ tions, far from indicating that writing is in an imperfect condition, evince that penmanship is far advanced. The Armenian alphabet consists of 38 letters. They have several other kinds of writing. We have given that which is called the round hand, and is used in printed books. Like ourselves, they write from the left to the right. The appearance of their printed books is neat and agreeable. The leaning of the letters was perhaps learn- ABET. 549 ed from the Italic, which was chiefly used by the Alphabet, printers of Venice. The greatest benefactors to their literature and typography have been the congregation of Armenian monks, who resided at Methone in the Pelo¬ ponnesus, and afterwards removed to Venice. This lan¬ guage possesses a few- original works, but is chiefly rich in translations from the writings of St Chrysostom and other Greek fathers, which have improved and refined it. Those who are curious on the subject may consult the disserta¬ tion of Schroder, De Antiquitate et Fatis Lingua Arme- naica ; and the historian of a nation, to whom it is said we owe the apricot, and who have always been renowned for skill in the ancient, delightful, and honourable art of gar¬ dening, Moses Chorenensis. The Iberian or Georgian letters, as expressed in types, are commonly somewhat lighter than our engraved alphabet of 36 letters. The Georgians write also from the left, and have several kinds of writing. The plate represents the ordinary hand. The Coptic language derives its name from Coptos, a city of Upper Egypt, where it was chiefly spoken. It is said to be a mixture of Greek with the ancient language of Egypt, Ethiopic, and the old Persian. The alphabet, which is borrowed from the Greek, superseded the use of the older letters in Egypt, as the characters introduced by Cadmus possibly took the place of those that were used by the Greeks before his time. The names, figures, and order of the letters, are the same as in Greek. Eight letters were added to express sounds unknown to the Greeks. Seven of these follow the omega; psi is put out of its place, being the last letter; and r, under the name So, is duly in¬ serted after the epsilon. This tongue has attracted some little attention, in consequence of the phonetic system, of which we have spoken. A full and handsome grammar was published at Rome in 1778, by the Society de pro¬ paganda Fide. The examples are given in Arabic, as wrell as Coptic. The Gothic alphabet of the patriarch Ulphi- las, which is the last of our specimens, was formed in part from the Latin, and in part from the Greek: the letters are arranged in the order of the former language. We know not whether certain theorists will consider the double letters at the end as syllabic characters. The Ru¬ nic alphabet is interesting from its connection with Scan¬ dinavian antiquities. It is nearly identical with the Ice¬ landic : the letters are copied from the Greek and Roman, being a little varied for the sake of notching them more conveniently on sticks or staves ; but the order of the six¬ teen letters is very different from both these alphabets. There are many specimens in Hickes’s Thesaurus. These letters have afforded much scope for controversy. Those who are most favourable to the antiquity of the Runic in¬ scriptions assign to them nearly 2000 years. Olaus Rud- bechius teaches that the Greeks used these letters before the time of Cadmus. Those who are least so say that they are not older than the third century of our era. The best kind of Anglo-Saxon writing was very elegant; the small round clraracters that we see in charters are neat and extremely legible. Domesday book is written in a hand less perfect, but’somewhat similar. After the Norman con¬ quest writing deteriorated in England, and became quaint, affected, and illegible. In proportion as a nation js civilized or barbarous, the pronunciation of its language, it has been maintained, varies from the orthography. In the Celtic languages the variation is prodigious; in our own tongue it is very considerable; in the Anglo-Saxon, so far as we are able to judge, it was much less. That language was assiduously cultivated before the conquest, especially in poetry; many poems were composed, and in extremely difficult and complicated metres. After that event French became the language of the aristocracy ; and the Saxon 550 A L P H Alphabet or English was long neglected, and was spoken only by the vulgar, for a long period, during which the foundations of our present orthography were laid. The Irish claim “ an exorbitant antiquity” for their tree alphabet, in which the order of the letters is peculiar, and the name of each of them is borrowed from some tree. B, under the name Beith, which signifies a birch- tree, is the first of them: it is fit that the tree of know¬ ledge should lead the band. This alphabet is commonly al¬ lowed to be a modern fabrication : a few antiquaries, how¬ ever, are ready to maintain that it is many centuries older than the creation. In most languages words are pro¬ nounced in a manner somewhat different from that in which they are written; but in the Irish the aberration of the sound from the spelling is so great, that the only use of letters seems to be, to show how words are not pro¬ nounced by omitting all that are really wanted, and insert¬ ing all but the right. As straight lines placed in differ¬ ent positions will form most of the letters of the Roman alphabet, so the various arrangement of lines, shaped like wedges or the heads of arrows, would make a sufficient variety of characters not altogether dissimilar to the Roman. Two of them inclining towards each other at the bottom would be V, one wedge at right angles to another might represent L, and three might be so placed as to designate either F or H. It is not necessary to pursue the subject farther. The structure of the arrow- headed, cuneiform, or ancient Persian alphabet, must be already sufficiently intelligible. Inscriptions in this cha¬ racter, which perhaps was also esteemed sacred, closely resemble the Runic Ogham, represented in General Val- lancey’s Irish Grammar. The twenty-five instructive and excellent plates in the second volume of the Collection of Plates, published with the French Encyclopedic, contain many curious spe¬ cimens of alphabets. They are taken, however, almost entirely and without acknowledgement, after the man¬ ner of the French literati, from the valuable publica¬ tions of the Society de propaganda Fide at Rome. M. du Marsais, the writer of the article on the alphabet in that Encyclopedic, evinces a passionate desire to regenerate the world—such was the taste of the age —and strenuously recommends a new alphabet: had it been adopted, according to his advice, we should un¬ doubtedly be using the old one at the present day. The numerous publications of the Society we have mentioned well deserve attention; and many curious alphabets are given in Niebuhr’s Travels, and in other works that we need not enumerate. We have spoken already of the advancement which the arts of reading and writing have received from religion: we will mention a very remark¬ able and important alphabet, which derived its origin and its general diffusion from the same source. The Arabic letters are said to be the invention of the unfortunate Vizier Moclah, who flourished at the beginning of the 10th century, and lost at different times, for political offences, his right hand, which had thrice copied the Koran, his left hand, and his tongue; cruel privations for a man of letters and an elegant penman. The Cuphic, a most grave and goodly character, appears to stand in the same vene¬ rable relation of paternity to the Arabic, as the Estranghelo to the vulgar Syriac. In the Arabian Nights, that faith¬ ful mirror of eastern manners, we find that the second Calender, who was a king’s son, after describing his critical knowledge of the Koran, and of the commentaries on “ that blessed book,” boasts of his excellent penmanship thus: “ But one thing, which I highly admired and succeeded in to admiration, was to form the characters of our Arabian language, wherein I surpassed all the writing-masters of ABET. our kingdom that had acquired the greatest reputation.” Alpha The Arabic character, especially as it has been modified j by the Persians, who have added to it much elegance, with some affectation, is not only favourable to the most daring flights of the pen, but in an eminent degree also to rapid execution. Wherever the Koran penetrated it was received, and it superseded the older and more tedious modes of writing. This alphabet consists of twenty-eight or twenty-nine letters, for it is a question whether Lam-alif is to be accounted a letter; but it has as much right to the title as 4/, and some others in the Greek alphabet, and it can plead a proverb in its favour, “ from alif to lam-alif” being exactly equivalent to “ from alpha to omega.” For twenty-eight or twenty-nine letters there are only seventeen primary figures, and these perhaps may be reduced to fifteen ; and the letters of which the figures are similar are distinguished by the number and position of certain dots, which are called dia¬ critical or distinctive points. It is precisely as if a nume¬ ral were added, as a co-efficient, to a letter in order to change its power entirely (we refer to this alphabet with¬ out a plate, as being generally known): thus, lb is b, but 2b perhaps is j, 3b is n, 4b is t, and fib is th; again, If is f, but 2f is k, and so with the rest. It is impossible to conceive a more clumsy device, or one more fruitful in mistakes, especially as they are distinguished, not by nu¬ merals, but by dots, which are easily omitted or misap¬ plied. The Persians have added four more letters, by means of additional dots, without introducing a new figure. They content themselves, nevertheless, with a smaller number than the Arabs, and the same as the Greeks, for the purposes of their own tongue ; never using eight of the letters except in words adopted from the Arabic. Thus, with the Romans k, y, and z, held offices in the foreign department only. The Persians vary the character in many hands, some of which are very beautiful, others very legible, and others very rapid. The Indians, when they write in the Arabic character, increase the number by three more letters, which they distinguish by additional points. The order of the Arabic letters has been changed; for their numerical value is the same as that of the twenty-two equivalent letters in the Hebrew, the six let¬ ters that have been added differ in their points only, and not in figure. It is a remarkable difference, that in the lan¬ guages of the East, at least in that family which is called Semitic, the vowTels are not expressed, but only the conso¬ nants. On the contrary, in all the languages of the West, the vowels and consonants enter equally into the compo¬ sition of the writing. Besides the twenty-eight or twenty- nine letters, eleven other marks are used in the Arabic. In the Semitic family the vowels are not of the essence of the word, the radical meaning resides entirely in the consonants, and so is it also in the Teutonic tongues. In our ow n we have, for example, sang, sing, song, and sung, and innumerable other instances. Whatever may have been, therefore, the parent of the Greek, it is impossible to agree with Colonel Vans Kennedy, who maintains in his late work On the Origin of Languages, that the Teuto¬ nic tongues are the offspring of the Sanscrit, in which the vowels are radicals. It has been conjectured with some ingenuity, but without foundation, that the Arabic characters in which the vowels are not expressed were invented fof the common use of several dialects, in which the conso¬ nants alone were determined in an invariable manner, and the pronunciation of the vowels varied. They have certainly been applied thus, but they were invented to facilitate those who transcribed the pure Arabic of the Koran, as the Hebrew letters were used without points to ALP a] bet copy the Jewish law. Abbreviations and simple charac- f ters, that are of easy formation, are not merely advanta- Aljrrj. ,reous to the reporter, but are useful also to the man of ^ ^fetters, for instantly catching the warm thought as it is¬ sues from the imagination; and perhaps also as a cipher, that the rash surmise, the first hasty impression, may not be exposed to the rude gaze of those who, never being origi¬ nal themselves, never give birth to errors, and accordingly are intolerant of them in others. Short-hand, therefore, independently of its ingenuity, is so useful, that it de¬ serves notice in an essay on the alphabet; but we re¬ fer to it only to illustrate the Arabic. The use of an extremely simple character, which is very cursive, and joins easily, and of many contractions, and the total omis¬ sion, in languages like our own, where they are not radi¬ cal, of all the vowels, are the means by which the short¬ hand writer attains to expedition. These are the wings on which his pen flics; they are the characteristics also of the Arabic alphabet. Let us suppose that all Great Britain was smitten with an immense love of writing—printing being still unknown—and that it was deemed the chief good to copy as much as possible; that for this purpose all men learned short-hand, and, finding that it increased their powers, and the passion continuing, laid aside all the ordinary hands, so that they were forgotten. Such was the origin of the Arabic writing. When the short¬ hand writer would make his writing more legible, he adds the more important vowels by dots, and by various dia¬ critical marks resolves ambiguities and clears up difficul¬ ties. If it were necessary to explain it to children and to strangers, and to interpret the abbreviations of distant times—and it would be were stenography universal— many orthographical signs would be required, whereby men would in truth return to the course which they had formerly quitted. Such was the origin of the vowel points and their adjuncts. When we reflect that we have the very words of So¬ crates, as he spoke them, unless Plato and Xenophon have deceived us, we cannot wonder, since the power of letters is really so great, that men have sometimes attributed to them a little more influence than they possess. Hence originated the belief in magical spells, and charms, and characters; and certain mysterious properties were as¬ signed to writing, not only amongst the Pagans, but by ALPH-dSNIX, white barley-sugar, to which is given an extraordinary name, to render it more valuable. This, which is thought good for colds, is made of common sugar, boiled until it becomes easy to crack, when it is poured upon a marble table, greased with oil of sweet al¬ monds, and moulded into various figures with a brass crotchet. It is easily falsified with starch. ALPHERY, Mikipher, an English divine, was born in Russia, and of the imperial line. When that country was distracted by intestine commotions in the latter end of the 16th century, this gentleman and his two brothers were sent over to England, and recommended to the care of Mr Joseph Bidell, a Russia merchant. Mr Bidell, when they were of age fit for the university, sent them to Oxford, where the small-pox unhappily prevailing, two of them died of it. We know not whether this surviving brother took any degrees or not, b,ut it is very probable be did, since he entered into holy orders, and in the year 1618 was presented to the rectory of Wooley in Huntingdonshire, a living of no very considerable value, being rated under L.10 in the king’s books. Here he did his duty with great cheerfulness and alacrity; and al¬ ALP 551 many of the Christians. It is somewhat remarkable that Alphabet it has always been the practice from the earliest times, II and it still prevails in Catholic countries, for the bishop^ when he consecrates a church (the order of this ancient and venerable rite maybe read in the Pontificale), to in¬ scribe twice on the pavement, in the form of a cross, all the letters of the Roman alphabet. History assigns the highest antiquity to the most precious art of alphabetic writing. The author of the book of Job was familiar with it. Moses speaks of it constantly in the Pentateuch, and he acquired his human learning in Egypt, where it was necessarily well known at that time. The better opinion seems to be, that although Cadmus, the contemporary of Joshua, introduced an alphabet into Greece, which was accepted there, it was only taken in exchange for that which had been previously in use. Josephus, it is true, with his usual desire to exalt his own nation and its laws at the expense of the Gentiles, asserts, without hesitation, that letters were unknown in Greece even in the time of Homer, and to Plomer himself; and some of the fathers of the church, who piously but unfairly endeavoured to degrade the learning of the Greeks, accepted the assertion as well founded. The startling paradox of the Jew, whose nationality has been less doubted than his vera¬ city, has been maintained, at different periods, with much ingenuity: it is capable, however, of an easy refuta¬ tion. The more diligently we inquire, the more ample and unequivocal shall we find the testimony of history to be in favour of the antiquity of alphabetic writing, and also, as reason alone teaches us, that no other ever existed. The Egyptian hieroglyphics, the Chinese characters, and the supposed syllabic alphabets, have been examined, and they do not afford, as is commonly asserted, any clue to lead us to the invention of the alphabet. Since we are unable, either in history or even in imagination, to trace the origin of the alphabet, we must ascribe it, with the Rab¬ bins, who are prepared with authenticated copies of the characters they used, and of those of Seth, Enoch, and Noah, to the first man, Adam ; or we must say with Pliny, “ ex quo apparet aeternus literarum ususor we must admit that it was not a human, but a divine invention, and that the artist who made men, Prometheus, says truly, E^eugov auroi$ yoamiarm rs tfuWkffs/s. (u.) though he was twice invited back to his native country by some who would have ventured their utmost to have set him on the throne of his ancestors, he chose rather to remain with his flock, and to serve God in the humble station of a parish priest. Yet in 1643 he underwent the severest trials from the rage of the fanatics, who, not sa¬ tisfied with depriving him of his living, insulted him in the most barbarous manner. Having left Huntingdon¬ shire, he came to Hammersmith, where he resided till the Restoration put him in possession of his living again. He returned on that occasion to Huntingdonshire, where he did not stay long; for being upwards of 80, and withal very infirm, he could not perform the duties of his func¬ tion. Having, therefore, settled a curate, he retired to his eldest son’s house at Hammersmith, where soon after he died, much honoured and respected, and afford¬ ing a remarkable instance of the vicissitudes of the world. ALPHONSIN, in Surgery, an instrument for extract¬ ing bullets out of gunshot wounds. This instrument derives its name from the inventor, Alphonso Ferri, a physician of Naples. It consists of three ^ branches, which are closed by a ring. When closed and introduced 552 ALP ALP Alphonso. into the wound, the operator draws back the ring towards ''^N^^^'the handle, upon which the branches opening take hold of the ball; and then the ring is pushed from the haft, by which means the branches grasp the ball so firmly as to extract it from the wound. ALPHONSO I. king of Portugal, son of Henry of Burgundy, count of Portugal, grandson of Don Alonso, king of Leon and Castile, who, as the dowry of his wife Theresa, received part of the kingdom of Portugal. One Egas Munitz had the charge of his education from his father, the duties of which he executed with fidelity and success. In the year 1112 his father died, leaving him a boy only three years of age, when the reins of govern¬ ment and the care of the infant son fell to his mother Theresa. At the age of 18 he assumed the sovereign authority by the advice of the nobles of Portugal, who were highly offended at the growing partiality of his mother for Don Ferdinand Perez, count of Trastemara; for it was suspected that she intended to marry him. But Theresa was little disposed to resign the reins of go¬ vernment. Her party raised an army, which took the field to oppose the nobility who supported Alphonso ; but her adherents were defeated, herself taken prisoner, and kept in confinement during the remainder of her life. Not long after his accession to the throne, his abilities both to govern and to conquer received a severe trial, in several arduous enterprises, as well against the king of Leon and Castile, as against the Moorish princes, who then possessed great part of Spain and Portugal. The Moorish emperor in Barbary having sent a strong rein¬ forcement to the princes, they were enabled to take the field with an army far superior to that of Alphonso; yet he valiantly met them in the plains of Ourique, and to¬ tally defeated their forces. Thus Providence conferred such a signal favour on the Christian arms as procured a residence for Christianity in those parts. The ambitious king of Leon and Castile assumed the title of empe¬ ror of the Spaniards, and entered Portugal to waste and destroy; but after the emperor had received a temporary check, the matter was accommodated, and he withdrew his army. In consequence of the victory obtained on the plains of Ourique, Alphonso was instantly proclaimed king; but the form and constitution of the monarchy were not settled until the nobility, prelates, and commons had assembled at Lamago for that purpose in the year 1145. The conquest of Santarem preceded this event, and was sanctioned by the unanimous concurrence of the states. The honour of crowning the king was conferred upon the archbishop of Braga; and it was legally provided that the crown should descend with an uninterrupted succession to the heirs male of Alphonso. The pre¬ lates and nobility, with the concurrence of the people, instituted a code of laws, consisting of 18 statutes, for the government of the kingdom. It being proposed whether it was their pleasure that the king should go to Leon and do homage to that prince or to any other, every man, drawing his sword, exclaimed, “ We are free, and our king is free, and we owe our liberty to our courage; and if he shall at any time submit to such an act, he deserves death, and shall not either reign over us or among us.” The year after his coronation he was married to Matilda, daughter of Amadeus, count of Maurienne and Savoy; and he reco¬ vered Lisbon from the hands of the Moors in the year 1147. A multitude of adventurers being assembled at the mouth of the Tagus in their progress to the Holy Land, greatly assisted him in this conquest. After having added six other provinces to his dominions, he wisely began with industrious activity to regulate the affairs of his kingdom. In all his great and benevolent designs he was vigorously seconded by Matilda, a prin- Alph L cess equally celebrated for her great beauty, mental vi-'wA ^ gour, and singular piety. He was no less provident in peopling and improving, than enterprising in acquiring territories. The conjugal felicity of this prince and princess was greatly enhanced by a numerous offspring, which enabled him, by great alliances, to strengthen his interests. His second daughter was married to Don Ferdinand, king of Leon, who, notwithstanding this al¬ liance, ungenerously made war on his father-in-law, and took him prisoner in the field of battle ; but released him, on the humiliating condition of coming in person to do homage for his dominions at Leon. In the latter part of his reign, his son Don Sancho, who inherited all his fa¬ ther’s military talents, took the lead on several occasions; and in the year 1180, Joseph, king of Morocco, and em¬ peror of the Almohedes, advancing with an army as far as Santarem, he there gained a glorious victory over him. Such was the consternation of the infidels, in consequence of this defeat, that they left the Portuguese at liberty to improve the interior part of the country, and to fortify their frontiers during the whole of next year. Worn out with care and intense application, Alphonso retired to Coimbra for repose, where, after a reign of 57 years, and in the 76th year of his age, he died. In the church of the holy cross at Coimbra his remains were deposited with great funeral solemnity. He was no less than seven feet high ; and his gigantic size and martial ar¬ dour have given occasion to many absurd and incredible stories concerning his military achievements, so that, in the annals of chivalry, as well as in the records of martial exertions, he sustains a very high rank. Alphonso II. distinguished by the surname of \heFat, was the third king of Portugal, and succeeded his father, at the age of 27 years, in 1212. He commenced his reign with two very popular acts. The one was, sending a body of infantry to the assistance of the king of Castile, who fought with uncommon bravery in the renowned bat¬ tle of Navas de Tolosa; the other was, his donation of the castle of Avis to the knights of that order, when the grand-master removed from Evora, and took up his habi¬ tation in that castle. His father having discovered that he disliked his brothers and sisters, endeavoured to secure them from the effects of his resentment, by con¬ ferring upon them large sums of money and jewels, and some of the best parts of the kingdom. After the death of his father, Alphonso strenuously laboured to convince them that it was not in the power of his father to separate or give away any part of his dominions; but all his urgent eloquence proving unsuccessful, he had re¬ course to arms. The two princesses, his sisters, who had received by the grant of their father very extensive and valuable property, upon being attacked by their brother, implored the interference of the pope, and also applied to the king of Leon to grant his protection, so that they made a very vigorous defence. The pope granted the re¬ quest of the young princesses, and threatened to excom¬ municate Alphonso; and from Galicia Don Ferdinand entered the dominions of Portugal to ravage and destroy; but the king prepared to defend himself against the arms of the king of Leon, and, by specious pretences, to evade the excommunication of the pope. Authors are not agreed with respect to the success of this war, but it is generally supposed that, by the inter¬ ference of these two powerful persons, the domestic affairs of that house were restored to a certain degree of tran¬ quillity. However, the departure of the infant Don Ferdi¬ nand to the court of Castile, and of Don Pedro to another place, strongly indicate that the reconciliation was far A L P Alionso. from being perfect. The conduct of the king, however, v^v-O produced much diversity of opinion among the common people of Portugal. Some were induced, by his argu¬ ments, to conclude that it was not in the power of Don Sancho, the late king, to dismember his kingdom; and others very properly suspected the kindness of a prince to his people, who displayed such uncommon and such unjustifiable hatred to his own relations; at the same time, ■those nobles whom the father had solemnly sworn to carry ■his will into execution, were induced, by a regard for the sacred nature of their oaths, to act against the reigning A L P 553 prince. The displeasure of the pope, however, was not to be en¬ dured. The mind of Alphonso seemed indeed to be of that quality which little regarded the displeasure or thunders of his holiness; but the effects of his threaten- ings were very different upon the public mind, conse¬ quently the king was constrained to seek the favour of the pope, that he might retain the obedience of his sub¬ jects. The king therefore sent deputies to Rome, who argued, that the crown his father wore was the purchase of the blood and valour of the Portuguese nation, and therefore not at his disposal; that it was a dangerous pre¬ cedent, and obviously tended to subvert the sovereignty of if state ; that the disuniting of the kingdom would tend to promote the cause of the infidels; and, in fine, that his disputes with his sisters had no connection with ecclesias¬ tical matters. The pope, however, was as well qualified to discern the nature of these specious arguments as the •prince was qualified to urge them, consequently he re¬ mained unmoved; and Alphonso, in order to have the sentence of excommunication which had been pronoun¬ ced upon him removed, was reluctantly induced to be re¬ conciled to his sisters. His holiness, informed of the re¬ conciliation, with great ceremony revoked his curse and excommunication from the king and his subjects. But the reign of this prince was destined to troubles; for no sooner was this domestic broil terminated than the Moors rushed into the plain country in such prodigious numbers, that the king found it very difficult to repel them, or to drive them back to their own country. A favourable occurrence, however, enabled him to complete his object, by the taking of a fortress seated on a rock which was deemed impregnable, in the following manner. The Germans and Flemings had equipped an immense fleet destined for the Holy Land, consisting of 300 sail, with a numerous army on board. In consequence of tempestuous weather, their fleet was so disabled that they were forced to put into the harbour of Lisbon to re¬ fit, just at the time when Alphonso was preparing an army to attack the Moors. The king instantly sent some of the most respectable men of his court to solicit their aid against the Moors, alleging, that it was perfectly consistent with their vows to fight against the Moors in Portugal, as well as in the Holy Land. William earl of Holland and many other generals were convinced by this argument, and cheerfully engaged to join him against the infidels; but about a third part of the fleet refused to join, and pro¬ ceeded on their voyage. It happened, however, that they were driven by a violent storm into Italy, where they wintered. The greater part of the nobility and gentry anded under the conduct of William earl of Holland ; and jt was resolved that they should proceed by sea, and UP Alca9ar-do-Sal, the fortress already mentioned, w ue the army of Alphonso, reinforced by a considerable number, should march by land; and thus attack the place th by land and sea at once. The Moors, convinced of « import Mice of this place, brought an army into the e ^ consisting of 50,000 men; but the Christians raised VOL. II. the siege, gave them battle, and routed them with great Alphonse, slaughter; and some of the chiefs of the Moors fell in the' VoA ^ie fortress surrendered on the 21st of October 1217, and was conferred upon the order of St James • but notwithstanding very urgent entreaties, the pope would not permit the army to winter in Portugal. He was de¬ sirous of having these troops and their general removed to a greater distance. The writers of that nation affirm that the soldiers experienced supernatural aid in this bat¬ tle, and that the banner of the cross was actually display¬ ed by angels. J But civil animosity succeeded to infidel war. The arch¬ bishop of Braga was highly offended that the clergy were forced to pay money and furnish troops to carry on the war against the infidels; and the people severely com¬ plained of the strictness of the laws. To chastise the re¬ bellious clergy, the king seized upon the revenues of the bishop, and forced him to fly from his dominions. En¬ raged at this impious conduct, the pope excommunicated the king, and laid his kingdom under an interdict. The natural consequence was, that all things were thrown into confusion, and consternation and perplexity universally prevailed; so that Alphonso was obliged to consult mea¬ sures to quell the rising discontent. It happened, how¬ ever, that in the midst of these negotiations he was re¬ moved by death, and not only died under the papal male¬ diction, but left his kingdom under the same curse. He was interred without royal honours, in the conventual church of Alcoba^a. Alphonso III. Don, king of Portugal, succeeded his brother Don Sancho II. in the year 1248. In the course of a war with the Moors, in which he engaged at the be¬ ginning of his reign, he considerably extended the Portu¬ guese dominions. He took possession of the city of Faro, the capital of the Moorish kingdom, in the province of Algarve. Louie, another Moorish town, which was car¬ ried by storm, also fell into his hands. His power Was thus extended abroad by the success of his arms, and the ad¬ ministration of his affairs at home became prosperous and popular by his wisdom and prudence. But the tranquil¬ lity and prosperity of the kingdom were somewhat dis¬ turbed by an interdict which it was put under by Pope Alexander IV., whose displeasure he had incurred by marrying Donna Beatrix, the natural daughter of Don Alonso the Wise, king of Castile, while his first wife was living. In 1262, when his first queen died, the interdict was removed by Pope Urban, a dispensation was granted, and the children of Donna Beatrix were legitimated. Hitherto frequent disputes had occurred between the kings of Portugal and Castile relating to the boundaries of the two kingdoms. To terminate all differences on this subject, and to prevent them in future, commissioners were appointed to define and settle the limits of their respective dominions; and these were agreed to and ac¬ knowledged by a solemn deed. Encouraged by the prosperity of his kingdom, and by the success which had attended his enterprises, Alphonso made an attempt to extend the influence of the crown, by obliging the clergy to contribute to the welfare of the state. But this measure, as might have been expected, was not quietly submitted to. It occasioned the revival of old disputes, the pope interfered, and in 1268 the kingdom was again laid under an interdict. Alphonso suc¬ ceeded, by the wisdom of his negotiations, in obtaining from Castile an exemption from all claims upon the crown of Portugal, and in procuring an acknowledgement that its monarch s were entirely relieved from the perform¬ ance of every kind of homage. He died in 1279, in the 69th year of his age, and in the 31st of his reign. Before 4 A 554 ALP ALP Alphonso. his death he was reconciled to the pope and clergy, ' having made a full and ample submission. Alphonso IV. king of Portugal, surnamed the Brave, was the son of King Denis. Instigated, it is said, by the queen dowager of Castile, and moved with jealousy against his natural brother Alphonso Sanchez, he revolted against his father, and commenced a civil war. In this unnatural and base war he was justly unsuccessful; but although he was reduced to subjection, yet his haughty and ungo¬ vernable temper broke out in many occurrences, until he succeeded his father in 1324. He commenced his reign with devising plans for the security of his family in the government, and the good of the kingdom: he likewise manifested a strong benevolence of heart, in his affection for his consort Queen Beatrix, and his dutiful conduct towards his mother. Not long after, he engaged in war with Alonzo XI. king of Castile, which, after several severe struggles, witl^ various success on both sides, ter¬ minated in an alliance, and in effectual assistance against the Moors. The artful and cruel part which he acted towards Donna Agnes de Castro, the mistress and con¬ cealed wife of his son, reflected the greatest disgrace upon his character. It is proper, however, to remark, that he was instigated to the murder of this princess by his cour¬ tiers. It was not therefore to be wondered at if his son was induced by this act to rise up in open rebellion against him ; but the arms of his father were too formidable ; and after his submission his father treated him with particular marks of attention. Instructed by the growing infirmities of years, he saw the termination of his reign and life ap¬ proaching. He began to compensate for his past errors and faults by redressing grievances, by restraining immo¬ rality through the establishment of pious laws, by dictat¬ ing salutary maxims for the government of the state, by removing those from the seats of power who were the most likely to become the objects of resentment after his death: he thus laboured to efface from the remembrance of his son the insult which he had received. While con¬ certing these conciliatory measures, he died in May 1357, in the 32d year of his reign, and the 67th of his age. In many respects he deserves the character of a great man and a great king,—brave and fortunate in war, but artful and indirect in his political measures, attached to his subjects, strict in the administration of justice, attentive to the public welfare, and assiduous in encouraging indus¬ try and enriching his people. Alphonso V. Bon, king of Portugal, was born in 1432, and on account of his heroic deeds obtained the surname of the African. At the age of six years he succeeded his father King Edward. The administration of the affairs of the kingdom during his minority was intrusted to his uncle Don Pedro, who, although his public conduct met with general approbation, was persecuted as a traitor at the expiration of his regency, and, with several persons who were attached to his interest, and involved in his misfortunes, was put to death. The young king had married the daughter of the regent; but even his influ¬ ence, which was overpowered by the regent’s enemies, could not save him from persecution. Afterwards indeed he did justice to his memory, and discovered an unusual mark of respect and attachment to his queen, by abstain¬ ing from all connection with the sex after her death, which happened in 1455, and, it has been supposed, was occa¬ sioned by poison, administered by the enemies of her father. Alphonso aspired to the acquisition of military glory. In the year 1458 he made great preparations to attack the Moors in Barbary. He assembled an army of 20,000 men, and equipped a fleet of 200 sail. He first directed his arms against Alcazar, which soon fell into his hands ; and, to maintain the footing which he had gained, he fur- Alph nished this place with a strong garrison. For twelve yearsv-^\ he prosecuted the war in Barbary with various success, in that time reduced Arzilla and Tangier, and in 1470 re¬ turned to Portugal loaded with honours. It was then that he obtained the surname of African, and to the titles which he derived from his ancestors, added that of lord of the coasts of both seas; and, with a view to perpetuate the memory of these exploits and conquests, he caused a re¬ presentation of them to be wrought in tapestry, a monu¬ ment surely constructed of very frail materials, but not less durable than many which have been erected by am¬ bition and vanity. During the war in Africa, a military order denominated the knights of the sword was founded. Alphonso was less successful in supporting the claim of his niece Donna Joanna to the crown of Castile against Ferdinand and Isabella. Finding his own resources un¬ equal to the contest in which he was engaged, he took a journey to France to solicit the aid of Louis XI. But his solicitations proved fruitless; and the mortification which he experienced from this faithless monarch filled him with melancholy, and induced him to resign his crown for the purpose of making a pilgrimage to the Holy Land. The administration of affairs during his absence was committed to the hands of his son Don Juan, who governed the kingdom with great ability. When the king returned he was joyfully received by the prince, and reinstated in his authority. But the mind of Alphonso had lost its wonted vigour, and was unfit to resume the arduous duties of government. Oppressed still with a deep melan¬ choly, he determined at length to withdraw from the cares of a kingdom, and to end his days in the repose and quiet of a monastery. But, on his journey to the place of his retirement, he was seized with the plague at Cintra, where he died in 1481, in the 43d year of his reign, and the 49th of his age. The moderation, the prudence and wisdom, which this prince exhibited in his public conduct, were not more powerful in conciliating the love and veneration of his subjects, and of all good men, than were the amiable virtues of his private character. He was distinguished for his affability and condescension, his benignity and bounty, and especially for his unbounded charity. In the exercise of this latter virtue he was honoured with the title of redeemer of the captives, in consequence of his having procured the freedom of many prisoners, whose ransom he cheerfully paid. Nor was he less eminent for his chastity and temperance, his attachment to letters, and his love and encouragement of learning. The first library in the palace of the kings of Portugal was founded in his time. He established and vindicated, against the pretensions and hostile attempts of the Spaniards, a very profitable trade on the coast of Guinea, which country was discovered during his reign, under the auspices of his uncle Don Henry, a celebrated character of that age. Alphonso VI. Bon Enriquez, king of Portugal, as¬ cended the throne when only a child of thirteen years of age. It is not easy to conceive a kingdom in a more peril¬ ous situation than this at the death of Don John. The young king was remarkable for weakness of body and im¬ becility of mind ; the regency in the hands of a woman, and that woman a Castilian ; the nation involved in war, and this respecting the title to the crown ; many of the nobility engaged in feuds and contentions with each other, and some of them secretly disaffected to the reigning fa¬ mily ; so that the queen scarcely knew to whom she could trust, or by whom she was to be obeyed. A very inde¬ cent joy was manifested by the people on the king’s death, as if his death was the dissolution of government; but the great abilities of the queen, and the vigorous mea- ALP Al onso, sures which she adopted, soon changed the face of affaifs. ^ For her own safety, and the prosperity of the kingdom, she appointed Don Francisco de Faro, count of Odemira, of the house of Braganza, governor to the king, and one of her principal ministers of state; and she made choice of Don Antonio de Meneses, count de Castenheda, to be his coadjutor. The former was a person in high repute among the nobility, in great favour with the people, en¬ tirely devoted to the interests of the queen, possessed of a large estate, and far advanced in years; the latter was also an aged man of great talents, and equally capable to preside in the cabinet and to command in the field. As might naturally be expected, these men sometimes differ¬ ed in opinion ; but this difference never hurt the cause of file queen. Seconded, protected, and counselled by such able men, the nation began to feel the effects of the queen’s firmness and superior talents. The first important exertion of the queen was, to send express orders to the count de San Lorenzo, who com¬ manded on the frontiers, to act offensively; but the mea¬ sure, though prudent in itself, was not attended with the desired success. About this time, however, the duke de St Germain, an Italian officer in the service of Spain, enter¬ ed Portugal, and besieged and took Olivenza and the castle of Moran. In consequence of this, the general was dis¬ missed, and his place was filled by Juan Mendez Yascon- celles, a man in great favour with the troops, and univer¬ sally popular. He engaged to act also upon the offensive ; but being unsuccessful, he was only saved from punish¬ ment by his simple and candid defence, in which he says, “ that he had undertaken the siege in obedience to the order of the queen, and for the honour of the nation; and that he had raised it without orders, for the preserva¬ tion of the army; that he knew the hazard he ran when he did it, but that it gave him pleasure to think, that at the hazard, or even the loss, of his reputation and life, the troops of Portugal had been saved.” He was declared innocent, and worthy of the queen’s favour, by the coun¬ cil of war who presided. Don Sancho Manuel, who com¬ manded in Elvas, and defended it with equal bravery and conduct, showed himself to be an officer of considerable judgment, by his hazarding nothing more when he had performed his service, upon which the very being of the state depended; but it was the count de Castanheda who raised that siege, and forced the army of Spain in their lines. After some other political measures, the queen regent finished in a manner her administration with the marriage of her only daughter, the princess Ca¬ tharine, once intended for Louis XIV., with Charles II. king of Great Britain, one of the most fortunate events that ever happened for Portugal, since it immediately procured them the protection of the English fleets, be¬ sides adding much reputation to their affairs throughout Furope; which was the reason that the Spanish court op¬ posed it with so much heat, or rather passion. By the vigorous exertions and fortunate victories of Montesclaros, me war was soon terminated to the honour of Portugal. I he sixth and last victory in the course of 28 years was obtained by the marquis de Marialva, which was chiefly owmg to unforeseen accidents, to the determined cou¬ rage of foreign troops, and to the great abilities of Schom- oerg. This victory determined the fate of the kingdom, though not of the sovereign ; and it was easy to be seen y he more intelligent people in Portugal, that the king *ould sooner or later be deposed. Alphonso being struck with the palsy while a child, ocame necessary to treat him with indulgence, on ac- ^1S )vea^isfate °f health; consequently, as he e haaturity, his want of parts, and the defects in his ALP 555 an idea of preferring him ; but they universally declined to make a breach in the succession, declaring it was diffi¬ cult to make an estimate of the powers of a king who was then only a child. The queen yielded, and endeavoured by every proper means to make him worthy of a crown which, by birth, he was entitled to wear. The count de Odemira, who was charged with his education, found it a V6!J i Afr* t^k1t0 manage the young prince, who, for¬ getful of his birth and destination, was prone only to those amusements which the youth of his age were ac¬ customed to. His guardian and preceptor struggled with tins disposition, and even ventured to take some pretty severe measures; but, to his great mortification, it proved entirely abortive. A variety of facts that might be men¬ tioned are sufficient evidence that his natural dispositions were weak, wild, refractory, and unteachable; and that although he was born to reign, yet he was destitute of the qualities absolutely necessary in a prince. The direful consequences of this having "been for some time experi¬ enced by the nation, the nobles were at last driven to the resolution of deposing the king, and exalting Don Pedro to the regency. In the morning of the next day after the determination, the marquis de Cascaes, at the head of the council, went to the palace to propose the resignation to the king. The king was in bed and fast asleep: the mar¬ quis ordered him to be awakened, and knocked violently at the door for that purpose; and when he obtained ad¬ mission, he is said to have upbraided him in very coarse terms for his laziness and inattention to public affairs at so critical a conjuncture ; adding, that since he must be sensible of his want of abilities to govern a kingdom, the wisest method he could adopt was, to resign it in favour of his brother. The king absolutely refused to consent; but not long after, Don Pedro coming to the palace, or¬ dered him to be confined in his apartment, where one of his favourites persuaded him, in the hope of being set at liberty, to make a short renunciation of the crown in fa¬ vour of his brother Don Pedro and his lawful issue, re¬ serving the house of Braganza and its dependencies, to¬ gether with 100,000 crowns out of the revenue of the crown. Nor was this deemed sufficient; for a paper was presented to him, making him avow, that for want of con¬ summation his marriage was null. This he at first de¬ clined ; but, by the advice of some divines, he was pre¬ vailed on to subscribe the deed. The unfortunate Don Alphonso died, after he had been a prisoner near fifteen years, when he had borne the title of king almost twenty- seven, and had lived about forty. Alphonso III., surnamed the Great, king of Asturias, was born in 847, and succeeded his father Ordogno in 865. In consequence of the rebellion of Don Frolia, not long after his accession to the throne, he was forced to leave his kingdom; but that usurper being assassinated, with universal applause he returned to his throne. In many successful enterprises against the Moors, in which he greatly enlarged his territories, he soon displayed the ta¬ lents of a warlike and able prince. He formed a power¬ ful alliance against the Moors, by marrying Ximene or Chimene, descended from the house- of Navarre, which paved the way for a long series of victories. The great attention which he paid to the comfort and welfare of the common people greatly disgusted his haughty nobles, which excited them to revolt against him in the advanced part of his life. Enjoying a small interval of tranquillity from the distraction and tumults of war, he called a ge- 556 ALP ALP Alphonso. neral council of the clergy and nobility, enacted some 'useful regulations, and directed their attention to several other subjects, which contributed to the honour and hap¬ piness of his kingdom. Whilst he was busily occupied in repairing some of those towns which he had taken from the Moors, he was suddenly interrupted by them, and was under the necessity of defending himself with a consider¬ able army, which he did with such success, that they were defeated with great loss. The unnatural rebellion of his son Don Garcias, at this time, greatly disturbed his government; but by the diligence of the lather, this un¬ natural rebellion was soon quelled. The confinement of Garcias, and the new imposition of taxes, produced gene¬ ral murmurs among the people ; which induced Alphonso, now worn out with years and incessant contentions, to. as¬ semble the states, and resign the reins of government into the hands of his son Don Garcias. He gave other son Don Ordogno the province of Galicia. The ambitious and military spirit which Don Garcias discovered in his father’s reign soon displayed itself in an attack on the Moors. By the advice of his father, to which he prudent¬ ly listened, he was taught that these new conquests tend¬ ed more to enrich the soldiers than to promote the interest of the crown. Alphonso, though far advanced in years, took upon himself the command of the army raised for new operations, and returned to Zamora loaded with spoils, and with increased reputation and fame, in the year 91.2. He died on the 20th of December 912, two years after his abdication, 46 years from the time of his being asso¬ ciated with his father in the government, and when he was about 64 or 65 years of age. His great learning, and the patronage he gave to literature, his distinguished piety and virtue, and other princely qualities, raised this king high in the estimation of mankind. Some writers affirm that he composed a chronicle of the Spanish affairs, from the death of Recesuintho to tiiat of his own father Don Ordogno, which has been incorrectly published by Sandoval, and the later editions have sustained considerable injury. Alphonso X., surnamed the Wise, king of Leon and Castile, succeeded his father Ferdinand in the year 1252. He obtained the appellation of wise, not for his political knowledge as a king, but his erudition as a philosopher. In consequence of the general opinion of his princely qualities, and his uncommon generosity, he ascended the throne with universal approbation. The ill-concerted projects of his ambition, however, disturbed the prosperity of his reign. Pretending a better right than Henry III. of England to that territory, he directed his first attempt against Gascony. The arms of England, however, proved too formidable ; and he was compelled to renounce his claim, on condition that Henry’s son, afterwards King Edward I., should marry his sister Eleonora. At an ex¬ pense which drained his treasures, and obliged him to debase his coin, he prepared for an expedition against the Moors in Barbary; but his maternal right to the duchy of Suabia, which he was called to defend, diverted him firom it. Thus he formed a connection with the German princes, and became a competitor, with Richard earl of Cornwall, for the imperial crown, in quest of which they both expended immense sums of money. I he claims of several of the princes of the blood gave exercise to his military talents, and he was successful both in opposing, and defeating them. He formed the romantic design of visiting Italy in the year 1268; but the states firmly remonstrating, he was obliged to relinquish it. But although he abandoned the design, yet it produced such discontents among the common people, and conspiracy among the nobles, that it required considerable exertion be¬ fore the king could allay the ferment. Alphonso being still desirous to ascend the imperial throne, attempted it after a the death of Richard earl of Cornwall, and even after U Rodolph of Hapsburg was actually elected emperor of Germany; and for that purpose took a journey to Beau- caire, to obtain an interview with the pope, in order to prevent him from confirming the election. The Moors, ever ready to draw the sword against him, took this op. portunity of entering his dominions for the purpose of ra¬ vaging them. This ambitious journey, undertaken at so vast an expense, and productive of so much confusion in his kingdom, proved unsuccessful; for the pope would not realize his claim, or alter the former election. But his excessive ambition was soon punished by domestic cala¬ mity; for his eldest son died in this interval, and his second son Don Sanchez, having obtained great reputa¬ tion in opposing the infidels, to the prejudice of his bro¬ ther’s children, laid claim to the crown. This claim was admitted by the states of the kingdom; but Philip king of France, supporting the cause of the children, whose mother was his sister Blanche of France, involved Al¬ phonso in a war; and it occasioned the retreat of his own queen Yolande or Yiolante to the court of her father, the king of Arragon. While thus harassed with dissensions, he proclaimed war against France, and by the authority of the pope he renewed the war with the Moors, which proved so unfortunate, that he reluctantly concluded a truce with them, and engaged in a contest with the king of Granada. These various measures exhausted his trea¬ sure ; taxes were multiplied, and the affairs of the kingdom were in such confusion, that he was under the disagree¬ able necessity of calling an assembly of the states, which was held at Seville in the year 1281, where, on the king’s proposal, the states consented to give a currency to copper money. In consequence of the intrigues of Don Sanchez, his son, another assembly of the states was held at Valla¬ dolid, A. d. 1282, which deprived Alphonso of the regal dignity, and appointed Sanchez regent. Reduced to almost insurmountable difficulties, Alphonso solemnly cursed and disinherited his son, and by his last will, in the year 1283, confirmed the act of exclusion, and ap¬ pointed for the succession the infants de la Cerda, and, upon the failure of their heirs, the kings of France ; and at the same time supplicated the assistance of the king of Morocco against the power of his son. At the commence¬ ment of the next year, when Alphonso received informa¬ tion from Salamanca that Sanchez was dangerously ill, his heart relented. He pardoned his son, revoked his curses, and then died, on the 4th of April 1284, in the 81st year of his age. His remains were interred in the cathedral of Seville ; and he left behind him the character of a learned man, but a weak king. Alphonso has been charged with irreligion and impiety, chiefly on account o a well-known but differently interpreted saying of his, viz. “ if he had been of God’s privy council when he created the world, he could have advised him better. He was an eminent proficient in science, and a patron of literature. He concluded that book of laws known y the title of Xas Partidas, which his father had begun, and in it displayed the abilities of a politician as we as of a legislator. By obliging his subjects to use their own language, he redressed the confusion in law proceedings occasioned by intermixing Latin with the vulgar Under his patronage a general history of Spain was co posed, which he took great pains in polishing ; ie. a ^ corrected many errors in the statutes of the universi y Salamanca. Astronomy being his favourite stu y, chiefly directed his attention to the improvement o science; so that, even during the life of his 1 sembled at Toledo a number of the most, celebrated ALP tronomers of his time, Christians, Jews, and Arabians, a/'-'from all parts of Europe, for the purpose of examining the astronomical tables of Ptolemy, and correcting their errors. These tables, after employing them about four years, were completed in 1252, the first year of Alphonso’s reio-n, and were called Alphonsine Tables, from the name of this prince, who, by his unbounded liberality, encourag¬ ed the construction of them. It is reported that 400,000 ducats were expended on them, or, according to others, 40 000. A book entitled The Treasure is also ascribed to him, containing treatises of rational philosophy, physics, and ethics. He is likewise said to have been well acquaint¬ ed with astrology and chemistry, and in the latter science to have compiled two volumes in cipher, which are still extant, and to be found in his Catholic majesty’s library. Alphonso V. king of Arragon and Naples, succeeded his father in the year 1416. As the father had formerly been honoured with the appellation of Just, so the son was honoured with that of Magnanimous. The conspi¬ racy of some of his own nobles against his life, together with the insolence of Pope Benedict XIII., greatly dis¬ turbed the tranquillity of his reign. Fortunately, this conspiracy was discovered just when it was about to be carried into execution; and, instead of proceeding with rigour against the conspirators, he generously tore a paper containing their names, without reading it, and added, that “ he would at least force them to acknowledge that he had a greater regard for their lives than they had for his.” After quelling a disturbance in Sardinia, and while em¬ ployed in making preparations to advance to Sicily, Joan of Naples offered, if he would assist her against the pope, the duke of Anjou, and the constable Sforza, who had formed a confederacy to depose her, to adopt him as her son and heir. He readily accepted the proposal, and with a powerful army soon raised the siege of Naples, and was immediately declared heir apparent of her kingdom, and duke of Calabria. The queen refusing to fulfil her en¬ gagements, Alphonso took possession of Naples, and ex¬ pelled her from it; but when the duke of Anjou again entered her territories, and made himself master of great part of them, she was obliged to renew her solicitations to Alphonso, who, in the year 1434, involved himself in a quarrel with the duke of Milan and the republic of Genoa, by besieging Gaeta in a second attempt to conquer Naples. In an engagement with the Genoese fleet, all his ships were dispersed or destroyed, and himself taken prisoner; but such was the address of this prince, that when carried to Milan a prisoner, he there ingratiated himself so much into the duke’s favour, that he became his friend and ally, and soon rose to greater power than ever. He got possession of Naples in 1443; and in an assem¬ bly of the states held at Beneventum, and afterwards transferred to Naples, his sovereignty was recognised, and Ids son Don Ferdinand declared successor to the throne; and, in consequence of this elevation, he was deemed the sole arbiter of peace and war through all Italy. Naples became the residence of Alphonso during the remainder of bis life; but his declining years were much disquieted by political dissensions and intrigues. Suspicion, the fre¬ quent attendant of old age, at last seized him; and, in con¬ sternation and dread, he was removed from one castle of Naples to another, until he breathed his last on the 22d or June 1468, bequeathing to his natural son Ferdinand me kingdom of Naples, and to his brother Don Juan, king of Navarre, the kingdoms of Arragon, Valencia, Majorca, ardinia, Sicily, and the principality and dependencies of atalonia. Alphonso was not only deemed the ablest statesman and the most renowned military commander ALP in that age, but also the greatest prince that ever occu¬ pied the throne of Arragon. ALPHONSUS TOSTATUS. See Tostatus. ALPINI, Prospero, in Latin Prosper Alpinus, a celebrated physician and botanist, was born at Marostica, in the republic of Venice, in November 1553. In his early years his inclination led him to the profession of arms, and he served some time in the Milanese. By the encouragement and persuasion of his father, who was a physician, he retired from the army, and devoted his at¬ tention to literature. To prosecute his studies with more advantage, he went to the university of Padua, where he was soon after elected deputy to the rector, and syndic to the students. But in the discharge of his official duties, which was distinguished by prudence and address, he was not prevented from pursuing the study of physic, which he had chosen. He continued his medical studies with zeal and success ; and after having acquired the ne¬ cessary qualifications, he was admitted to the degree of doctor of physic in 1578. Soon after this he left the uni¬ versity, and settled as a physician in Campo San Pietro, a small town in the Paduan territory, at the invitation of its citizens. In the course of his studies he had paid particular at¬ tention to plants, and had become an enthusiast in bota¬ nical science; but the sphere of his present practice was too limited to afford him much opportunity of prosecuting his favourite study. He wished particularly to extend his knowledge of exotic plants; and considered that the only means of attaining this was to study their economy and habits in their native soil. To gratify this laudable curiosity an opportunity soon presented itself. George Emo, the consul for the Venetian republic in Egypt, ap¬ pointed Alpini his physician. They sailed from Venice in September 1580, and, after experiencing a tedious and dangerous voyage, arrived at Grand Cairo in the begin¬ ning of July the following year. Alpini spent three years in Egypt, and, by his industry and assiduity, greatly im¬ proved his botanical knowledge, having travelled along the banks of the Nile, visited every place, and consulted every person from whom he expected any new informa¬ tion. From a practice in the management of date-trees, which he observed in this country, Alpini seems to have deduced the doctrine of the sexual difference of plants, which was adopted as the foundation of the celebrated system of Linnaeus. He says, that “ the female date-trees, or palms, do not bear fruit unless the branches of the male and female plants are mixed together; or, as is generally done, unless the dust found in the male sheath, or male flowers, is sprinkled over the female flowers.” When Alpini returned to Venice in 1586, he was ap¬ pointed physician to Andrea Doria, prince of Melfi; and during his residence at Genoa he acquired so great a name as to be esteemed the first physician of his age. The Venetians were unwilling that the Genoese state should number among its citizens a person of such distinguished mex’it and reputation, whose services might be essentially beneficial, and whose fame might be highly honourable, to his native country; and in the year 1593 he was recalled to fill the botanical chair in the university of Padua, with a salary of 200 florins, which was afterwards augmented to 750. He discharged the duties of his professorship for many years with great reputation, till his declining health interrupted his labours. He died in 1617, in the 64th year of his age, and was succeeded as botanical pro¬ fessor by one of his sons. Alpini wrote the following works in Latin:—1. De Medicina TEgyptiorum libri iv. Venice, 1591, 4to; 2. De Plantis iEgypti liber, Venice* 1592, 4to; 3. De Balsamo Dialogus, Venice, 1592, 4to; 558 ALP Alpiste 4. De Prsesagienda Vita et Morte iEgrotantium libri vii. [| Venice, 1601, 4to; 5. De Medicina Methodica libri xiii. Aips. paciua5 1611, folio ; 6. De Rhapontico Disputatio, Padua, 1612, 4to. Of all these works there have been various editions given to the world; and, besides these, two post¬ humous treatises were published by his son : 1. De Plantis Exoticis libri ii. Venice, 1627, 4to; 2. Historiae Naturalis Egypti libri iv. Lugd. Bat. 1635, 4to. Several other works of Alpini remain in manuscript. ALPISTE, or Alpia, a sort of seed used to feed birds with, especially when they are to be nourished for breed¬ ing. The alpiste seed is of an oval figure, of a pale yel¬ low, inclining to an isabel colour, bright and glossy. It is an article of the corn-chandlers and seedmen s trade. ALPS. On taking a general view of the continent of Europe, we can distinguish two great mountain masses, from which proceed the various chains of mountain groups that characterize it. The first of these is the mountain mass of St Gothard, in Switzerland, between the sources of the Rhine, the Rhone, the Etch, and the Aar: the second is the Wolchonshy-wald, in Rus¬ sia, between the Wolga and the sources of the Don, Dnieper, and Dwina. The mountains connected with St Gothard are the Alps, which in their full extent reach from long. 4° 20' to 19° E. from Paris, and from lat. 44° to 47° N. The central point of the Alps is in Switzerland, the numerous branches of it extending through Savoy, France, Italy, Germany, Croatia, and Sclavonia. They are bounded on the south-west by the Rhone, in southern France ; on the north-east by the Danube, in Hungary; on the south and south-east by the Mediterranean Sea, and the rivers Kulpa and Sau; on the north and north-west by the Da¬ nube, in Germany; by the Rhine on the northern boundary of Switzerland; and by the Doubs on the Jura. Hence it appears that this great high land passes through France, Savoy, Switzerland, Italy, Germany, Croatia, and Sclavo¬ nia. The southern part of the chain in Croatia, in long. 35°, does not reach its extremity, but continues onwards to the left bank of the Sau and Danube, fully ten de¬ grees of longitude farther. Origin of In the Celtic language, the word alb, alp according to the name, some authors, signifies white. As the highest peaks of this Alpine land are perpetually covered with snow, they were by the ancient inhabitants named Alps; by the Greeks AXcrs/f, who, however, knew only the Maritime Alps; by the Romans Alpes, and by modern writers Alps.1 History. The Romans, although they knew well that the Gauls under Bellovesus (620 years before Christ) made an irruption into Upper Italy across the Alps, were entirely ignorant of the route he followed. It was not until Hannibal had crossed the Alps (300 years after Bello¬ vesus) that the Romans thought of examining this grand barrier. Polybius described the Alpine country tra¬ versed by the military host under Hannibal, fifty years after that remarkable event; and Cincius Alimentus heard Hannibal himself detail his passage of the Alps. Livy, and other writers, both Latin and Greek, also speak of the Alps. Fifty-two years after Hannibal’s irruption into Italy (in the year of Rome 587, before Christ 178), the Romans, under the consuls Claudius and Marcellus, conquered the Cisalpine Gauls, who inhabited the coun¬ try between the Po and the Alps; and seven years after¬ wards, under Fulvius Nobilis, they for the first time crossed the Alps to Nice and Antibes, in order to aid the Marsilians against the Ligurians. For one hundred and A L P fifty years from this period, the Romans frequently tra- A1 versed this chain, partly with the view of subjugating the^\ various tribes inhabiting it, and partly in extending their conquests into Spain, Gaul, and Germany. After the death of Caesar, the whole Alpine population threw off the Roman yoke. The emperor Augustus sent against them (in the year of Rome 747, before Christ 18) his le¬ gions, under Drusus, Tiberius, Terentius Varro, and Lu¬ cius Silus. This long-continued warfare terminated in the conquest of forty-six Alpine tribes or nations, whose names were inscribed on the celebrated triumphal arch of Augustus, erected near Nice. From this period until the fifth century after Christ, the Romans continued in com¬ plete possession of the north and south sides of the Alps. During the long domination of the Romans, the Alps received the following names, which are still retained by geographers, viz. Maritime, Cottian, Grecian, Pennine, Leopontine, Rhaetian, Noric, Carnic, Julian, and Dinarian. DIVISIONS OF THE ALPS. 1. Maritime Alps (Alpes Maritime).—These extend Divis from the coast of the Mediterranean Sea, between Onegliaoftlie and Toulon, across the Cols Ardente and Tende, to Mont Viso (Vesulus), separating Piedmont from Provence and the Mediterranean Sea. 2. Cottian Alps (Alpes Cottiae) extend from Mont Viso by Mont Genevre to Mont Cenis, a distance of twenty-five leagues, thus separating Piedmont from Dau- phiny. It is in this range that we first meet with heights analogous to those of the central chains of the Alps. The Po and the Durance rivers have their sources here. The name is derived from Cottius, who, in the time of Caesar and Augustus, had his chief place of residence at Seguvium, the present Susa, and ruled as king or chief of this part of the Alps. 3. Grecian or Grey Alps (Alpes Graiae) extend from Mont Cenis, across the leran and the Little St Ber¬ nard, to the Col de Bonhomme, separating Piedmont from Savoy. They were named Grey Alps from their grey colour, owing to the partial cover of snow. The Little St Bernard is considered as the Alpis Graia of the ancients. 4. Pennine Alps (Alpes Penninae), also named by Caesar Alpes Summae, extend from the Bonhomme across Mont Blanc, the Great St Bernard, Combon, onwards to Mont Cervin and Mont Rosa, separating Piedmont from Savoy and the Lower Vallais. The Celts named every high mountain a Penn; hence the loftiest sum¬ mits and the most exalted of their deities were named Penn. In the time of the Romans, in one of the valleys, a temple was built, and a statue erected in it, to one of their gods, named Penn, by the Romans Deus Pen* ninus, and afterwards Jupiter Penninus. Hence these Alps were named Alpes Penninae. In this part of the great Alpine range there occur Mont Blanc, the highest mountain in Europe, and Mont Rosa, the next in elevation to that monarch of European mountains. 5. Leopontine Alps, also named Alps of Switzerland, or Aulae. They extend from Mont Rosa on both sides of the Rhone, or valley of the Vallais, across St Gothard, the Moschelhorn, and Bernardino in the Grisons, thus separating Lombardy from Switzerland. The distance from St Gothard to Bernardino is 15 leagues. . They were named Leopontine after a people, the Leopontii, who formerly inhabited the confines of Rhaetia, Helvetia, and Italy. 1 Some authors derive Alp from dtb, a verdant height. ALPS. 539 6. Rhatian Alps (Alpes Rhaeticae) extend from Ber- i Onardino through the whole of the Grisons and the Tyrol, to the Dreiherrn peak, on the borders of Saltzburg and Carinthia, and more southerly to Mont Pelegrino; thus separating Lombardy and a great part of the Venetian terra firma from Northern Rhaetia and Germany. 7. Noric Alps (Alpes Noricae) extend from the Drei¬ herrn peak through the whole of Carinthia, on the left bank of the Drau, through Saltzburg, Austria, and Styria, to the Oedenburg plain in Hungary. They have their name from the Roman town Noricum. 8. Carnic Alps (Alpes Carniae) extend from Pelegri¬ no, between the rivers Drau and Sau, to Terglou, at the source of the Sau. 9. Julian Alps (Alpes Juliae) extend from Terglou, between the right bank of the Sau, the Kulpa, and the Adriatic Sea, to the rock Kleck, near Zenk in Dalmatia; thus separating the Friaul from Idria, and in general the whole of Upper Italy from Carinthia, Carniola, Croatia, and Servia. The present Civita di Friuli occupies the site where formerly stood the Forum Julii, which gave name to this division of the Alps. 10. Dinarian Alps, so named from Mons Adrius, ex¬ tend from Kleck to Sophia, ranging along the right bank of the Sau and Danube, and join the Haemus or Balkan, on the Black Sea. Dir ion The general direction of the Alps, excluding the Ma- oftljUps.ritime Alps, which range nearly from south to north, is Dir ion from west-south-west to east-north-east. The most con- ' eys. siderable valleys, those named longitudinal, run parallel with the direction of the chain; and others, named trans- verse, run from south and south-east to north and north¬ west, or from north and north-west to south and south¬ east. Grajac- The great crest of the Alps, the watershed (divortia chv Is of aquarum) 0f this vast high land has declining from it two 11 ^ acclivities, one towards the north, the other towards the south. The north acclivity declines towards the ocean, the North Sea, and the Baltic; the south acclivity towards the Mediterranean and Adriatic Seas. The northern acclivity has a gentle inclination, and is much more ex¬ tensive than the southern, which is comparatively abrupt and steep. From the nature of these two acclivities or inclined plains, we naturally expect to find the principal and most numerous secondary chains on the northern, and this is actually the case. Mont St Gothard, in some de¬ gree the central point of the whole chain, is distant in a straight line from the Mediterranean about 52 leagues, from the Adriatic 75 leagues, from the ocean 175 leagues, from the North Sea 168 leagues, from the Baltic 185 leagues.

The Elbruz in the Caucasus, which is 16,411 feet, cannot be reckoned a European mountain. Notwithstanding its vast height, Mont Blanc is much inferior in elevation to some mountains in the New World and in Asia; for, according to late measurements, there are in Upper Peru mountains 25,250 feet above the sea; and in the Himalaya ridge summits soaring to a height of 26,000 feet. 10. Great St Bernard 11,011 11. Mont Cervin 14,784 12. Mont Rosa 15,540 Welden. Mont Rosa is the next in elevation to Mont Blanc, and therefore the second highest mountain in Europe.

Where the earth’s surface attains this height, it is, with the exception of mural precipices, continually covered with snow. The snow increases from season to season; for though it may melt slowly from the heat of the ground on which it rests, yet it sulfers little loss externally in the way of melting, except what the air carries off by evaporation. If in the neighbourhood of Edinburgh we had mountains 6000 feet high, their summits would be always covered with snow, and consequently we should here have perpetual snow within a few hours’ walk. But in Great Britain none of the mountains reach to the snow line of the latitude,—an ar¬ rangement very different from what prevails in the Alps, where whole ranges are covered with eternal snow. When motmtains are covered with perpetual snow, its lower limit, or the snow line, descends in winter and rises again in summer; so that in the Alps in winter the snow line reaches the low country, while in summer it ascends, and in the autumn, when the heat is greatest, it attains its maximum of height. The lower edge of the snow line differs much from that above it, and might more properly be called the ice line, because the snow, owing to the influence of rain, the heat of the sun, and the heat of the earth, is there partially melted every summer, and frozen again in the winter, forming an icy boundary. This ice is named glacier ice, or svcnfiy glacier. Above this zone, the region of the glaciers, the snow is seldom moistened by rain or softened by the rays of the sun. These glaciers or vast accumulations of ice have received particular names in different parts of the Alps. Those in Dauphiny and Savoy are named glacier; in Switzerland, gletcher ; in the Grisons, wader ; in the Tyrol, ferner; in Salzburg and Carinthia, has; and by the Italians who inhabit the Alps, vedretto. They fill all the upper, and principally the transverse valleys, from Dauphiny to ^ j, the frontier of Salzburg: few of them are less than three^k' miles, many 18 or 20 miles in length, from one to two miles broad, and from 100 to 600 feet thick. They frequently run into each other, and thus surround the peaks on all sides, in such a manner that they appear rising like islands through a sea of ice. Where the glaciers are largest, they send down great arms or branches into the cultivated country, and into the fruitful valleys, 3000 feet above the sea. The chain of Mont Blanc affords a striking example of these descending arms; for there are twenty-five glaciers, descending from it into the val¬ leys of Chamouny, Entreves, and Bionnay. The glaciers are frequently traversed by rents, often of great width and depth; so that when hid by a thin covering of snow or ice they become extremely dangerous to travellers. It is therefore proper to have experienced guides when visiting the dreary and desolate scenes where they oc¬ cur. The unfortunate Mr Escher, mentioned by M. de Luc, was cautioned by his guide not to separate from his companions when they arrived at the glacier. Hur¬ ried on, however, by that indescribable sensation which people sometimes experience when they reach lofty summits, and observing at the top of the glacier, a little distance before him, two chamois hunters, who were resting themselves, he hastened to join them; but he disappeared in a moment, and was precipitated to the bottom of a frightful fissure. He met with an instantane¬ ous death, which was caused by the compression of his body in the narrow part of the rent. Bodies of those de¬ stroyed in fissures are sometimes brought to light by the glacier streams. Other adventurers have been even less fortunate than Escher; for there are instances in the me¬ lancholy records of these dreary regions, of bodies having been found uninjured, lying on projecting ledges in the fissures, and even sometimes suspended in narrow parts of these horribly dark gulfs ; thus showing that the wretched sufferers had had a slow and awful death. All around the lower edges of the glaciers there are vast heaps of stones : these are partly masses which have fallen from the mountains, on their surface, or which have been thrown from under the glacier in its progress downwards. The collection of earth and stones is termed by the inha-Mol bitants of Switzerland, moraine. The glaciers are not stationary, but occasionally move downward, and with a motion more or less quick. The movement of the glacier sometimes takes place unex¬ pectedly, as was experienced by the priest of the Grin- denwald, who, along with a chamois hunter, felt the glacier over which they were travelling moving under them. The travellers were resting themselves, and had lighted their pipes, when suddenly a frightful noise resembling thunder was heard. Every thing around them began to move: their fowling-pieces, which they had laid on the ice, moved about. Masses of rock, which a few moments before lay quietly on the surface of the glacier, bounded about in all directions; fissures closed with a loud noise, like that of cannon, and forced the water contained in them several fathoms upwards. New rents, from 10 to 12 feet, burst open with inde¬ scribably disagreeable noises. The whole mass of the glacier moved forward several yards: a dreadful convul¬ sion appeared approaching; but in a few seconds all was still again, and the dead silence was interrupted only by the call of the marmot. The total number of glaciers in Njw _r the whole range of the Alps may be between 500 andg 600, which together form an icy sea of enormous extent. These are masses of snow separated from the general A^a snowy cover, which in their course downwards carry-al A L ; s. ing along with them fragments of rock, and branches and trunks of trees, rapidly increase in size, and sometimes, before reaching the bottom of the valleys, have accumu¬ lated to an enormous magnitude. They destroy houses and villages, break down whole forests, and sometimes even interrupt the course of rivers. Those who are unfortunately enveloped in these avalanches have little chance of escape. In 1478 sixty soldiers in the district of St Gothard were destroyed by an avalanche. One hundred men were en¬ veloped in an avalanche in the Great St Bernard, in the year 1500. In 1595 the course of the Rhine was so much interrupted by the fall of a great avalanche across it, that the water rose and drowned many men and cattle. In 1624 three hundred soldiers were enveloped in an avalanche in Italian Switzerland, but the greater num¬ ber were dug out alive. Many other details of a similar description are to be found in the records of modern tra¬ vellers. The snows and glaciers of the Alps already described are the never-failing sources of water for the great rivers which rise from them, as the Rhine, Po, Danube, and Rhone. Po ation The inhabitants, as is well known, are in many respects oft Alps.highly interesting, more especially those inhabiting the more remote and magnificent districts. The population of the whole range may be between 6,000,000 and 7,000,000. Of these, from 1,000,000 to 2,000,000 belong to the Celto-Gallic stem, from 800,000 to 900,000 to the Italian, about 1,000,000 to the Sclavonian, and nearly 5,000,000 to the German states. Among these there may be at least 1,500,000 who lead a pastoral life, and who occupy themselves exclusively with Alpine economy and tlie rearing of cattle. Dii bu- In the Alps the upper limit of vegetation ascends above •>a: f the snow line; for we observe plants growing on mountains voi iblcs. situated above that line, but which are so steep that snow will not lie on their sides. Thus, an androsacea and a silene were found growing at a height of 1590 toises, on the mountains around Mont Blanc. At an elevation of 1728 toises, on the same group of mountains, there were found, growing and in a healthy state, a cardamine, a draba, a gen¬ tian, and other plants that do not fear the glacier zone. At elevations between 1282 and 1180 toises, where the snow and glaciers cease, we find growing, not upon rock, but on a fertile soil watered by the snow-water, dwarf willows in the midst of Alpine herbaceous plants. This region pre¬ sents here and there islands or patches of snow, in places screened from the sun’s rays. In the bare patches of ground among these islands, excellent clover grows, which, however, can only be reached by traversing these snowy patches. Lowrer down we reach that Alpine region so celebrated for the magnificent pasturages it contains; and still lower, between 1180 and 770 toises, new plants make their appearance; viz. the rhododendron ferrugi- neum, the rhododendron hirsutum, and ericaea or heaths. We find the alder at 1000 toises ; and here we enter into the region of trees. The pirnis muglms appears at 870 toises; the pinus picea, or pitch pine, at 750; the birch at 750 and 700; the yew at 700. The region of great trees does not ascend higher than 680 toises ; beech stops here. Oaks do not pass beyond 550 toises. At this height the cerealia cannot be advantageously cultivated. The cherry ranges upwards as high as 500 toises; nut-tree and ches- mjt to 400 toises. The vine is planted as high as 280. The olive is cultivated at the foot of the Alps, and on the coast of Italy; and there also we find the orange, the citron, and other trees. Local circumstances occasion changes in the limits of these vegetables: barley, oats, and wheat range to 700, and even to 900 toises. VOL. II. P s. The animal^ world exhibits similar distributions with the Alps, vegetable. T bus, the ibex and the chamois occur among the most elevated summits, amidst snow and ice; but ol'Bistribu- these two quadrupeds, the chamois in general occupies a tio.n of lower situation than the ibex. Lower down we meet withanimals* the marmot and the white hare, the bear and the mole; still nearer the low country, wolves, foxes, the lynx and the wild cat. Among the feathered creation the feathered vulture or lammergeyer is the species which is observed at the great¬ est heights, being seen soaring above very lofty snow- covered pinnacles. The ptarmigan wanders along the edge of the snowline ; theheath-cock frequents pine forests; the grey partridge and other birds occur in still lower regions. Various aquatic birds frequent the lakes and rivers, and have also their appropriate distribution. The distribution of fishes is also interesting, as they occur at different heights, whether in lakes or rivers. Where the water is abundantly supplied from the glaciers, fishes do not thrive, and are rarely to be found. Insects, too, as we shall partially explain in our article on the geography of the animal world, are met with in the Alps, from spots amidst the snows of the loftiest peaks to the deepest valleys, increasing in number, variety, and beauty, as we approach the lower country. Even the testaceous molluscae, and creatures lower in the animal scale, exhibit on the great acclivities of the Alps a similar mode of distribution. In this vast high land there are examples of all Geological the different rock formations of which the crust of thecomposi- earth is composed, from the deepest-seated primitive^011, rock to the most superficial and newest alluvial depo- site. The higher and also many of the deeper ranges and valleys are composed of primitive rocks, viz. gra¬ nite, gneiss, mica slate, clay slate, limestone, trap, por¬ phyry, syenite, serpentine, and quartz rock. Resting upon these, and frequently at a great height, rocks of the tran¬ sition class appear, as grey wacke, clay slate, quartz rock, granite, gneiss, mica slate, limestone, syenite, trap and serpentine. The secondary rocks, or those of the third class, although frequently occurring at a great height, yet more generally occupy lower situations than the primitive and transition rocks. The following secondary deposites are enumerated by authors as occurring in the Alps. We enumerate them in their order of deposition, beginning with the first or oldest. 1. First secondary sandstone, or coal formation. 2. First secondary limestone, or magnesian limestone. 3. Second secondary sandstone, or new red sandstone. 4. Second secondary limestone, or shell limestone. 5. Third secondary sandstone, or keuper sandstone and marl. 6. Third secondary limestone, or Jura, and Lias, and Oo¬ lite limestones. 7. Fourth secondary sandstone, or green and iron sand, and quader-sandstone formation. 8. Fourth secondary limestone, the chalk deposite of geo¬ logists. Resting upon these secondary deposites, we find in many parts vast accumulations of strata of newer rocks belonging to the fourth or tertiary class. These tertiary deposites consist of sand, sandstone, and conglomerate; of clays, marls, and coals, and of various limestones ; all more or less.abounding in fossil organic remains. The bottoms of the valleys, even their sides to a considerable height, are more or less covered with clays, sands, rolled masses, &c., belonging to the diluvium of authors. And we find in every situation, from the lofty peak to the bottom of the deep valley, spread over the other deposites already enumerated, a more or less deep cover of that alluvial de- 562 ALPS. Alps, tritus which is daily forming, and which consists of broken ~ ‘ masses more or less angular, gravel, sand, clay, loam-clay, shell-marl, peat, &c. The common vegetable soil rests upon this alluvium, in beds varying in thickness from a few inches to several feet. These secondary and tertiary rocks are variously inter¬ mingled with trap and old volcanic rocks, and the dilu¬ vial and alluvial deposites with newer igneous or volcanic rocks. No fossil organic remains occur in the primitive rocks ; few appear in those of the transition class ; whereas in the various members of the secondary and tertiary classes fos¬ sil plants and animals are abundant, and so disposed as to assist in characterizing the different deposites or for¬ mations. The diluvial and alluvial deposites also abound in fossil organic remains; but for details we refer to the article Geology. Varieties of almost every species of the European simple minerals are met with in the Alps or their connecting chains; and in the long range of this high land we find gold, and many different and valuable ores of silver, lead, copper, iron, bismuth, nickel, cobalt, zinc, manganese, mercury, antimony, arsenic, molybdena, uranium, tita¬ nium, and tungsten. These ores occur in veins, beds, imbedded masses, or are disseminated in rocks of various descriptions, particularly those of the primitive and transi¬ tion classes. The loftiest and most interesting mountains are Mont Blanc, Mont Rosa, the Great Glockner, and the Order, mountains, -ppg ascent to the summits of these cole ^al masses exhibits all those varied displays of scenery, of ch nate, and of distri¬ bution of animal, vegetable, and mineral production which so much excite the curiosity of the traveller and the natu¬ ralist. The ascent to the summit of the Great Glockner and the Order Spitze is described by Schultes and other travellers ; that of Mont Rosa by Saussure, but more parti¬ cularly by Von Welden, in his account of that mountain. Mont Blanc being more in the track of travellers, has ex¬ cited greater attention than any of the other great Alpine mountains. To reach the summit of the highest moun¬ tain in Europe has always been an object of desire with adventurous travellers; hence repeated attempts have been made to reach the top of Mont Blanc. Some of these have been successful, others have been the contrary. The first attempt to reach the summit was made in the year 1762, by Pierre Simon of Chamouny, who endeavour¬ ed to accomplish it by the Glacier du Buissons, and again from the French side ; but failed in both. Another unsuc¬ cessful attempt was made by some villagers in 1773 ; and again in 1783 by M. Bourrit of Geneva. Bourrit made a second attempt in 1784, which was also unsuccessful. In 1785 M. de Saussure, M. Bourrit, and M. Bourrit junior, with fifteen guides, left Bionassy in the beginning of Sep¬ tember, and ascended the glacier of the same name. They slept near the base of the Arguille du Gout6, and next day climbed to the summit of it; but the snow was so soft that they could proceed no farther. They re¬ turned to the place where they had slept the night be¬ fore, and next day descended into the valley. In June 1786 six Chamouny guides next attempted it, but gave it up through fatigue and fear: they were alarmed by the black appearance of the sky. Jacques Balma, as they were returning, strayed from the party, and lost his way among the hills and blocks of ice on the glacier, and was unable to regain his party. He remained all night in some hole or cave which he found in the ice. Next morning he wandered about, and discovered a route by which he thought he could reach the summit, and then returned to Chamouny with a determination to keep it a secret. Fossil or- ganic re¬ mains. Minerals and ores. Most re¬ markable Dr Packard, a native of Chamouny, had some suspicion A] that Balma knew an accessible track leading to the summit, and tried in vain to get this information from him; but they agreed at last to go together and make the attempt. Therefore, on the 7th of August 1786, they left the Priory, and slept on the summit of the mountain of La Cote. Thence they started next morning at four o’clock; and after surmounting many difficulties, they attained the summit at half-past six in the evening. They left it at seven, and about midnight arrived at the spot where they had slept the night before; and at eight o’clock on the morning of the 9th returned to Chamouny. M. de Saussure having heard of the success of this journey, hast¬ ened to the valley, and, with seventeen guides, immediately attempted to follow the route of Jacques Balma; but from the bad state of the weather he did not succeed. In July 1787 Saussure sent Balma to reconnoitre the glacier, who reported that it was not in a fit state ; but on the 1st of August this illustrious philosopher and indefatigable traveller left Chamouny at seven A. m., wfith a servant and eighteen guides. At two o’clock they arrived on the summit of the mountain of La Cote. Next day they crossed the glacier, and halted on the. second plateau at four. Here they passed the night, and next day gained the summit at eleven in the forenoon. They remained on it for nearly four hours, leaving it at about three o'clock, and descended to about 1100 yards below the summit, slept there, and next day reached the Priory. M. Bourrit set out on the enterprise on the day of their return, but bad weather drove him back. On the 9th August of the same year, Colonel Beaufoy, with ten guides, attained the sum¬ mit, having left Chamouny the day before, and returned to it on the 10th. He was enabled to ascertain that the latitude of the summit of Mont Blanc is 45° 49' 59" N. At twelve o’clock the mercury in the thermometer stood at 38° in the shade. At the same hour, in Chamouny, and in the shade, it stood at 78°. In 1788 M. Bourrit, his son, Mr Woodley, and Mr Camper, set out together; but when at a great height, a severe storm separated the party, of whom Mr Woodley was the only one who reached the summit, which was on the 5th of August He and his guides suffei’ed severely. M. Bourrit never attempted the ascent again. In 1791 four Englishmen made an unsuccessful attempt to reach the summit. On the 10th of August 1802 a native of Lausanne and a German, with seven guides, reached the summit. They remained on it twenty minutes, and then de¬ scended part of the way, performing the remainder and arriving at Chamouny on the 11th, having taken three days to accomplish it. On the 10th of Septem¬ ber 1812 M. Rodalz of Hamburg got to the summit.* On the 4th of August 1818 a Russian gentleman reach¬ ed the summit. On 12th July 1819 Dr Van Ranselaer and Mr Howard, Americans, ascended the mountain and reached the summit; and on the 13th of August of the same year Captain Undrell, R. N. made a successful at¬ tempt. On the 19th August 1820 Dr Hamel, a Mosco- vite, with three gentlemen and twelve guides, ascended to the great plateau. In climbing from it up the side of Mont Blanc, an avalanche swept away the whole party- Some of them extricated themselves; but three guides were driven into a crevice and perished. On the August 1822 Mr Clissold, who has published an account of his journey, reached the summit. On the 4th Sep¬ tember 1823 Mr Jackson arrived on the summit and dt'- scended the same day to Chamouny, being, it is understooc, the first who ever accomplished this arduous task in so short a time, having been absent only thirty-six hours an a half from Chamouny; but he remained on the summit on) ALP . g, three or four minutes. On the 26th August 1825 Dr E. Clarke and Captain M. Shenvill made the ascent, em¬ ploying three days in the expedition. On the 25th July 1827 M. C. Fellowes and M. H. Hawes gained the sum¬ mit, having discovered a new route. Their journey occu¬ pied nearly three days. On the 9th of August the sum¬ mit was attained by Mr Auldjo of Cambridge, who has published a highly interesting account of his journey. He says, “ My ascent to the Grand Mulcts was on the 8th, and thence to the summit on the following day, pur¬ suing the route discovered in July. I remained on the summit one hour, and descended to Chamouny the same day, being absent thirty-seven hours.” There have, therefore, been fourteen successful ascents, says Mr Auldjo; and, not including guides, eighteen persons have gained this great height. The majority of these are Englishmen, ten being their number. Of the rest, two are Americans, two Swiss, one Russian, one German, and one Savoyard. It is remarkable that no Frenchman has ever been on the summit. Some years ago a party of guides made the ascent for pleasure, and Maria de Mont Blanc, a high- spirited girl, accompanied them, being the only female who has ever reached the summit. Napoleon also ordered a party of guides to ascend, and plant a cross on the sum¬ mit, which was done; but it was blown down in a day or two afterwards. The most interesting accounts of the Alps are contain¬ ed in the following works:—Saussure, Voyages dans les Alpes, 4 vols. 4to; 2. Ebel iiber den Baa der Erde in dem Alpin-Gebirge, 2 vols. 1808; 3. Schultes, Reise durch Salz¬ burg, &c. 4 vols. 1804; 4. Alpina, 4 vols. 1806-9. (o.) Alps, besides its proper signification, by which it de¬ notes a certain chain of mountains which separate Italy from France and Germany, is frequently used as an ap¬ pellative to denote any mountains of extraordinary height or extensive range. In this sense, Ausonius and others call the Pyrenean Mountains Alps, and Gellius the Spanish Alps, Alpini Hispani. Plence also we say, the British Alps, meaning the Grampians, &c.; the Asiatic Alps, meaning the Altaic chain, &c.; the American Alps, meaning the Andes, &c. Alps, Lower, Department of, in France. This depart¬ ment is bounded on the north by the department of the Upper Alps, on the east by Piedmont and the depart¬ ment of the Maritime Alps, on the south by the depart¬ ment of the Var and the north-east extremity of that of the Mouths of the Rhone, and on the west by the de¬ partments of Vaucluse and the Drome. Its superficies is about 1,459,699 square acres, and its population about 149,500. It is divided into five communal districts. The chief town is Digne. Alps, Higher, Department of. This department makes a part of Dauphine. It is bounded on the north by the departments of Mont Blanc and Isere, on the east by Piedmont, on the south by the department of the Lower Alps, and on the west by that of the Drome and part of that of Isere. The soil consists of enormous mountains and narrow valleys. Two thirds of the surface are useless for agricultural purposes. The north wind, which generally prevails, renders the climate cold ; and the snow remains m some of the valleys eight months of the year. The principal river is the Durance, which is extremely rapid, and commits great ravages by its inundations. The su¬ perficies of this department is about 1,084,614 square acres, and its population 121,500. It is divided into three communal districts. Embrun is the principal town. Alps, Maritime, a department of France, formed of the county of Nice and part of High Provence, and of which Mce is the principal city. The chief products of this A L S 563 mountainous country are wine and oil, and its population Alpuiarras is about 131,000. y ALPUJARRAS, a mountainous district in the province Alsace- of Granada, in the south of Spain, to which the Moors ofV^v->^ the capital were banished after the destruction of their kingdom under Ferdinand and Isabella. It is a range pa¬ rallel to the Sierra Nevada, but separated from it by the river Grande, which runs to the Mediterranean by Mo- tril. The mountains are composed of a clayey slate highly favourable to the culture of the vine, and pro¬ duce the wine called Pedro-Ximenes, so highly prized in Spain. The declivity of this range is very rapid to the north, but on the south the descent towards the Medi¬ terranean Sea is very gradual, and the inclined planes are highly prolific. The highest part of the range is the Sierra de Luxar, which has an elevation of 6550 feet, and is covered with snow eight months of the year. ALQUIER, a liquid measure used in Portugal to mea¬ sure oil, two of which make an almond. ALQUIFOU, or Arquifou, is a sort of lead ore, which, when broken, looks like antimony. It is used by the pot¬ ters to give a green varnish to their works, and thence is called potters ore. It is met with in Cornwall, &c. The potters mix a small portion of manganese with the alquifou, and then the varnish or glazing on their ware is of a blackish hue. ALREDUS, Alured, or Aluredus, of Beverley, one of the most ancient English historians, was born at Be¬ verley, in Yorkshire. He wrote in the reign of Henry I.; but no circumstance of his life is known with any de¬ gree of certainty. It is generally believed that he was educated at Cambridge, and that he afterwards became one of the canons and treasurer of St John’s at Beverley; and we learn from a note of Bishop Tanner’s, that, for the sake of improvement, he travelled through France and Italy, and at Rome became domestic chaplain to Cardi¬ nal Othoboni. He died in the year 1128 or 1129, leaving behind him the following works :—1. The Annals of Alu¬ red of Beverley, published at Oxford in 1716, by Mr Hearne, from a manuscript which belonged to Thomas Rawlinson, Esq. It contains an abridgement of our his¬ tory from Brutus to Henry I., written in Latin, and with great accuracy, elegance, and perspicuity. 2. Libertates Ecclesite S. Johannis de Beverlac, &c. a manuscript in the Cottonian library. It is a collection of records relative to the church of Beverley, translated from the Saxon lan¬ guage. ALRESFORD, a market-town in the north division of the county of Hants, 7 miles from Winchester, and 58 from London. It consists of two parishes, having been in past ages a place of more consideration than of late years, as the river Itchen, on whose banks it is built, has long ceased to be navigable. In 1801 the population was 1132; in 1811, 1429; and in 1821, 1264. ALSACE, before the Revolution, a province of France, bounded on the east by the Rhine, on the south by Switzerland, on the west by Lorraine, and on the north by the palatinate of the Rhine. It was formerly a part of Germany, but was given to France by the treaty of Munster. It is one of the most fruitful provinces in Europe, abounding in corn, wine, wood, flax, tobacco, pulse, fruits, &c. The mountains which divide it from Lorraine are very high, and generally covered with fir, beech, oak, and hornbeam. Those on the side of Switzer¬ land are lower, and furnished with all sorts of wood, as well for fuel as for building. The country itself is diversified with rising hills and fertile vales, besides large forests; but that between the rivers 111, Hart, and the Rhine, as far as Strasburg, is inferior to the rest, on ac-« 564 A L S A L S Alsen count of the frequent overflowing of the Rhine. In High II Alsace there are mines of silver, copper, and lead. . There Alsop. are jron works in several parts of Alsace, and particularly ^v~x""/at Betford. At Sulzbach, near Munster, in High Al¬ sace, there is a mineral spring, which is in great reputa¬ tion for the palsy, gravel, and weakness of the nerves. The original inhabitants of Alsace are honest and good- natured, but wedded to their own manners and cus¬ toms. The fruitfulness of their country renders them in¬ dolent and inactive; for the Swiss make their hay and reap their corn, as well as manage the vintage of High Alsace. The common language is the German, but the better sort of people in the towns speak French; and even in the country they speak French well enough to be understood. The number of inhabitants since the peace in 1814 has been computed at 915,191. By the late division of France, this province forms two depart¬ ments, viz. those of the Upper and Lower Rhine; the capital of the former being Colmar, and that of the latter Strasburg. ALSEN, an island of Denmark, situated in the Little Belt, or entrance into the Baltic Sea, between Sleswick and Funen, 100 miles west of Copenhagen. It extends in length six leagues, and about two in breadth. The soil is fertile, producing abundance of fruit and variety of grain, with large crops of aniseeds, a carminative much used in seasoning food, and mixing with the bread, over all the Danish dominions. Long. 9. 55. E. Lat. 55. 12. N. ALSFELD, a bailiwick in the grand duchy of Hesse- Darmstadt, containing two cities and 25 other towns and villages, the inhabitants of which amount to 8700, in 1452 houses. Alsfeld, a city, the capital of the bailiwick of the same name. It is a manufacturing town, in which much coarse woollen cloth is made. It stands on the river Schwalm, has 500 houses, and 3019 inhabitants. ALSHASH, a very beautiful city in Bukharia, sup¬ posed to be the same with that which is now called Tashcant, the capital of the eastern part of Turkestan, possessed by the Kassats. It is situated on the river Sihon, now Sirr, and had a well-watered garden for every house; but was ruined by Jenghis Khan, who took the city, and caused a great number of its inhabitants to be massacred. ALSHEDA, a parish in the province of Smaland, in Sweden, where a gold mine was discovered in 1738. ALSIRAT, in the Mahometan Theology, denotes a bridge laid over the middle of hell, finer than a hair, and sharper than the edge of a sword, over which people are to pass, after their trial, on the day of judgment. To add to the difficulty of the passage, Mahomet affirms, that the Alsirat, narrow as it is, is beset with briers and thorns; none of which, however, will be any impediment to the good, who shall fly over it like the wind, Mahomet and his Mussulmans leading the way; whereas the wicked, by the narrowness of the path, the entangling of the thorns, and extinction of the light which directed the former to paradise, shall soon miss their footing, and tumble headlong into hell, which is gaping beneath to receive them. ALSO-KUBIN, a market-town in the palatinate of Arva and province of Hither Danube, in Hungary, with a Catholic and a Lutheran church, and a Jewish synaeoeue. Long. 19. 24. 45. E. Lat. 49. 14. 30. N. ALSOP, Anthony, an English divine and poet, was educated at Westminster School, and from thence elected to Christ Church, Oxford, where he took the degree of M. A. in March 1696, and of B. D. in December 1706. On his coming to the university, he was very soon dis- A1 tinguished by Dean Aldrich, and published Fabulanm^ JEsopicarum Delectus, Oxon. 1698, 8vo, with a poetical de¬ dication to Lord Viscount Scudamore, and a preface in which he took part against Dr Bentley in the famous dis¬ pute with Mr Boyle. He passed through the usual offices in his college to that of censor with considerable reputa¬ tion, and for some years had the principal noblemen and gentlemen belonging to the society committed to his care. In this employment he continued till his merit recommend¬ ed him to Sir Jonathan Trelawney, bishop of Winchester, who appointed him his chaplain, and soon after gave him a prebend in his own cathedral, together with the rectory of Brightwell, in the county of Berks, which afforded him ample provision for a learned retirement, from which he could not be drawn by the repeated solicitations of those who thought him qualified for a more public character and a higher station. In 1717 an action was brought against him by Mrs Elizabeth Astrey of Oxford, for the breach of a marriage contract; and a verdict was obtained against him for L.2000, which probably obliged him to leave the king¬ dom for some time. His death, which happened on the 10th June 1726, was occasioned by his falling into a ditch that led to his garden door. A quarto volume was published in 1752, under the title of Antonii Alsopi, JEdis Christi dim Alumni, Odarum libri duo. Four English poems of his are in Dodsley’s Collection, one in Pearch’s, several in the early volumes of the Gentleman s Magazine, and some in The Student. Mr Alsop is respectfully mentioned by the facetious Dr King as having enriched the common¬ wealth of learning by Translations of Fables from Greek, Hebrew, and Arabic; and not less detractingly by Dr Bentley, under the name of “ Tony Alsop, a late editor of the iEsopean Fables.” Alsop, Vincent, an English nonconformist divine, was born in Northamptonshire, and educated at St John’s Col¬ lege, Cambridge, where he took the degree of master of arts. When he received deacon’s orders, he went to Rutlandshire, and settled at Oakham, where he was an assistant to the master of the free-school. As he was a man of a sprightly turn, he fell into indifferent company; but was reclaimed by the frequent admonitions of the reverend Mr Benjamin King. He afterwards married that gentleman’s daughter, and becoming a convert to his principles, received ordination in the Presbyterian way, not being satisfied with that which he had from the bishop. He was settled at Wilbee, in the county of Northampton, whence he was ejected in 1662 for nonconformity. After this he ventured to preach sometimes at Oakham, and at Wellingborough, where he lived, and was once six months in prison for praying by a sick person. A book which he wrote against Dr Sherlock, in a humorous style, made him well known to the world, and induced Mr Cawton, an eminent nonconformist in Westminster, to recommend him to his congregation for his successor. On receiving this call he quitted Northamptonshire, and came to London, where he preached constantly, and w'rote several pieces which were extremely well received by the public. Living in the neighbourhood of the court, he was exposed to many incon¬ veniences ; but these ended with the reign of Charles II. or at least in the beginning of the next reign, when Mr Alsop’s'son engaging in treasonable practices, was freely pardoned by King James. After this our divine went fre¬ quently to court, and is generally supposed to have been the person who drew up the Presbyterians’ address to that prince for his general indulgence. After the Revolution, Mr Alsop gave public testimonies of his attachment to government; yet upon all occasions he spoke very respect¬ fully of King James, and retained a very high sense of his A L S ^ a. clemency in sparing his only son. The remainder of his 1 ,g iife he spent in the exercise of his ministry, preaching once every Lord’s day ; besides which he had a Thursday A tm' lecture, and was one of the lecturers at Pinners Hall. He ^ "^livedto agreat age, and, preserving his spirits to the last, died in May 1703. On grave subjects he wrote with a becoming seriousness; but where wit might properly be shown, he displayed it to great advantage. His funeral sermon was preached by Mr Slater, and his memory will be always preserved by his own learned and elegant writ¬ ings. Of these the most remarkable, besides his sermons, are, 1. Antisozzo ; in vindication of some great truths op¬ posed by Dr William Sherlock, 1675, 8vo ; 2. Melius In¬ quirendum ; in answer to Dr Goodman’s Compassionate Inquiry, 1679, 8vo; 3. The Mischief of Impositions; in answer to Dr Stillingfleet’s Mischief of Separation, 1680; 4. A Faithful Reproof to a False Report, with reference to the Differences among the United Ministers in London, 8vo. ALSTAHOUG, a city of Norway, the seat of a bishop, containing 4990 inhabitants, on the island Alster, in the bailiwick of Nordland and province of Drontheim, or, in the Norwegian dialect, of Tronheim. ALSTED, a barony in the bailiwick of Soroe and diocese of Zealand, in Denmark. It comprehends 17 parishes, contains 6000 inhabitants, and extends over 95 square miles. ALSTEDIUS, John Henry, a German Protestant divine, and one of the most indefatigable and voluminous writers of the 17th century. He was some time professor of philosophy and divinity at Herborn, in the county of Nassau. From thence he went into Transylvania, to be pro¬ fessor at Alba Julia, where he continued till his death, which happened in 1638, in the 50th year of his age. His Encyclopaedia, the most considerable of the earlier works of that class, was long held in very high estimation. It was published in 1630, in two large folio volumes. His Thesaurus Chronologicus is by some considered as one of his best works, and has gone through several editions. He also wrote Triumphus Biblicus, to show that the principles of all arts and sciences are to be found in the Scriptures. He was a Millenarian, and published, in 1627, a treatise Be Milk Atinis, in which he asserted that the reign of the saints on earth was to begin in 1694. ALSTON, Charles, M. D. a botanical and medical writer, was born in the west of Scotland in the year 1683. He began his studies at the university of Glasgow; and about this time he had the good fortune to be taken under the patronage of the duchess of Hamilton, which afforded him an opportunity of pursuing the bent of his inclination, by attaching himself to the study of physic. About the age of 33, along with his friend and companion the cele¬ brated Alexander Monro, he went to Leyden, and studied three years under Boerhaave. On their return to their native country, they, in conjunction with Rutherford, Sinclair, and Plummer, undertook departments in the col¬ lege of Edinburgh, and by their abilities and industry laid the foundation of that school of physic. The branches of botany and materia medica were long the favourite studies of his life, consequently he undertook that depart¬ ment, and continued to lecture on them with increasing reputation until his death, which happened in Novem¬ ber 1760, at the age of 77 years. His talents appear to have been naturally strong, which he improved and strengthened with great assiduity and industry, and employed successfully in the service of science. In the year 1753, his dissertation on the sexes of plants, in which he combats the doctrine of Linnaeus, was published ia the first volume of the Edinburgh Physical and Lite- alt 565 rary Essays. The general plan of the work is conducted Alston- with much ingenuity, supported by some strong experi- Moor ments; and although, in the opinion of the learned, it has II failed in its principal design, yet it must be acknowledged , r Altai. to be one of the best argued pieces on that side of the,^^111#' question. An asperity of language is sometimes used, very unsuitable to a scientific topic; but it is proper to remark, that Linnaeus had given some reasons for this conduct, by the nature of some of his descriptions. In the fifth volume of the Edinburgh Medical Essays, we have a short paper by Dr Alston, on the efficacy of the powder of tin to destroy or expel worms from the bowels. He informs us that he received the prescription from an empiric, who was renowned for his skill in curing persons afflicted with that disease. The patient received, the first morning, one ounce of tin reduced to powder, and half an ounce each on the two following mornings, and was then purged with the infusion of senna and manna. He speaks with great confidence of the efficacy of this medicine, which certainly has considerable power in these cases, and may be given to the most delicate subjects with per¬ fect safety. Dr Alston also engaged in a chemical con¬ troversy respecting quicklime with Dr Whytt. But the most valuable of all his works are his lectures on the Materia Medica, which were published in the year 1770, in two volumes 4to. The number of curious and useful facts contained in this book will tend to secure its reputa¬ tion, although considerable additions and improvements have been made since that period in this branch of science. ALSTON-MOOR. See Aldston-Moor. ALT, in Music, a term applied to the high notes in the scale. ALTAI Mountains, an extensive range of mountains, which forms the northern barrier of the great plateau or central table-land of Asia, the southern barrier being formed by the Himalaya Mountains. This immense mountainous chain traverses, in a semicircular direction, the whole breadth of the Asiatic continent, from 68° E. longitude to East Cape in 170° of E. longitude. It extends, under different names, about 5000 miles. The Ural Mountains may be said to be its commencement on the west, being the western boundary of Siberia. From thence the chain passes above the head of the Irtysch, when it takes a rugged and precipitous course, clothed with snow, and rich in minerals, between the Irtysch and Obi: it then proceeds by the lake Telezkoi, the rise of the Obi; after which it retires, in order to comprehend the great rivers which form the Yenesei, and are locked up in these high mountains: finally, under the name of the Sainnes, it is uninterruptedly continued to the lake of Baikal. A branch insinuates itself between the sources of the rivers Onon and Ingoda, and those of Ichikoi, accompanied with very high mountains, running without interruption to the north¬ east, and dividing the river Amur, which discharges itself into the east, in the Chinese dominions, from the river Lena and Lake Baikal. Another branch stretches along the Olecma, crosses the Lena below \akoutsk, and is con¬ tinued between the two rivers Tongouska to the Yenesei, where it is lost in wooded and marshy plains. The prin¬ cipal chain, rugged with sharp-pointed rocks, approaches and keeps near" the shores of the sea of Okhotsk, and, passing by the sources of the rivers Outh, Aldan, and Maia, is distributed in small branches, which range be¬ tween the eastern rivers which fall into the Icy Sea; be¬ sides two principal branches, one of which, turning south, runs through all Kamtschatka, and is broken, from Cape Lopatka, into the numerous Kurile Isles, and to the east forms another marine chain, namely, the Aleutian Islands, 566 ALT ALT Altamont which range from Kamtschatka to America; most of II which, as well as Kamtschatka itself, are distinguished by ^ Alt^ volcanoes, or the traces of volcanic fires. The last chain forms chiefly the great Cape Tschutski, with its promon¬ tories and rocky broken shores. The summits of the highest of the Altai Mountains are covered with perpetual snow. The loftiest range of this extensive chain is composed of granite. Another range of inferior height consists of schistos, which lies on the sides of the granite mountains. Besides these rocks, there are strata of chalkstone, limestone, and marble. The Altai Mountains abound in metallic ores. Gold, sil¬ ver, and lead mines, have been discovered in them, with great abundance of copper and iron. The two latter have been wrought to a considerable extent, and have been found productive. The Altai Mountains form the south¬ ern boundary of Siberia, as far as longitude 130° E., when they bend towards the north, and penetrate deeper into the country.

The heathens at first made their altars only of turf; afterwards they were made of stone, of marble, of wood, and even of horn, as that of Apollo in Delos. Altars differed in figure as well as in materials: some were round, others square, and others triangular. All of them were turned towards the east, and stood lower than the statues of the gods; and they were generally adorned with sculpture, representing either the gods to whom they were erected, or their symbols. The height of altars also differed according to the (Tifferent gods to whom they sacrificed. Accord¬ ing to Servius, those altars set apart for the honour of the celestial gods, and gods of the higher class, were placed on some pretty tall pile of building, and for that reason were called altaria, from the words alta and ara, a high elevated altar. Those appointed for the terres¬ trial gods were laid on the surface of the earth, and called ar

After this period we recognise only two History. names of any celebrity in the history of the science, those of Soranus and Oribasius, with the more obscure ones of Meletius and Theophilus, the latter the chief of the imperial guard of Heraclius. Soranus, who was an Ephesian, and flourished under the emperors Trajan and Hadrian, distinguished himself by his researches on the female organs of generation. He appears to have dissected the human subject; and this perhaps is one reason why his descriptions of these parts are more copious and more accurate than those of Galen, who derived his knowledge from the bodies of the lower animals. He denies the existence of the hymen, but describes accurately the clitoris. Soranus the ana¬ tomist must be distinguished from the physician of that name, who was also a native of Ephesus. Oribasius, who was born at Pergamus, is said to have been at once the friend and physician of the emperor Julian, and to have contributed to the elevation of that apostate to the imperial throne. For this he appears to have suffered the punishment of a temporary exile under Valens and Valentinian; but was soon recalled, and lived in great honour till the period of his death. By Le Clerc, Oribasius is regarded as a compiler; and indeed his ana¬ tomical writings bear so close a correspondence with those of Galen, that the character is not altogether groundless. In various points, nevertheless, he has rendered the Ga- lenian anatomy more accurate; and he has distinguished himself by a good account of the salivary glands, which were overlooked by Galen. To the same period generally is referred the anatomi¬ cal introduction of an anonymous author, first published in 1618 by Lauremberg, and more recently by Bernard. It is to be regarded as a compilation formed on the mo¬ del of Galen and Oribasius. The same character is ap¬ plicable to the treatises of Meletius and Theophilus. The decline indicated by these languid efforts soon sunk into a state of total inactivity; and the unsettled state of society during the latter ages of the Roman em¬ pire became extremely unfavourable to the successful cultivation of science. The sanguinary conflicts in which the southern countries of Europe were repeatedly en¬ gaged with their northern neighbours, between the second and eighth centuries, tended gradually to estrange their minds from scientific pursuits; and the hordes of barba¬ rians by which the Roman empire was latterly overrun, while they urged them to the necessity of making hostile resistance, and adopting means of self-defence, introduced such habits of ignorance and barbarism, that science was almost universally forgotten; and the art most essential to the success of military operations was either neglected or debased by the grossest ignorance. While the art of healing was professed only by some few ecclesiastics, or by itinerant practitioners, anatomy was utterly neglected ; and no name of anatomical celebrity occurs to diversify the long and uninteresting period commonly distinguished as the middle ages. Anatomical learning, thus neglected by European na¬ tions, is believed to have received a temporary cultiva¬ tion from the Asiatics. Of these, several nomadic tribes, known to Europeans under the general denomination of Arabs and Saracens, had gradually coalesced under va¬ rious leaders ; and by their habits of endurance, as well as of enthusiastic valour, in successive expeditions against the eastern division of the Roman empire, had acquired such military reputation, as to render them formidable where- 1 n.*ji Avu,T0fJUH.uiv Ey^sistirsay, lib. Vll. 692 ANATOMY. History, ever they appeared. After a century and a half of fo- reign warfare or internal animosity, under the successive dynasties of the Ommiades and Abassides, in which the propagation of Islamism was the pretext for the extinc¬ tion of learning and civilisation, and the most remorseless system of rapine and destruction, the Saracens began, under the latter dynasty of princes, to recognise the va¬ lue of science, and especially of that which prolongs life, heals disease, and alleviates the pain of wounds and inju¬ ries. The caliph Almansor combined with his official knowledge of Moslem law, the successful cultivation of astronomy; but to his grandson Almamon, the seventh prince of the line of the Abassides, belongs the merit of undertaking to render his subjects philosophers and phy¬ sicians. By the directions of this prince, the works of the Greek and Roman authors were translated into Arabic ; and the favour and munificence with which literature and its professors were patronised, speedily raised a succession of learned Arabians. The residue of the rival family of the Ommiades, already settled in Spain, was prompted by motives of rivalry or honourable ambition to adopt the same course; and while the academy, hospitals, and li¬ brary of Bagdad bore testimony to the zeal and liberality of the Abassides, the munificence of the Ommiades was not less conspicuous in the literary institutions of Cordova, Seville, and Toledo. Notwithstanding the efforts of the Arabian princes, however, and the diligence of the Arabian physicians, little was done for anatomy, and the science made no substantial acquisition. The Koran denounces as un¬ clean the person who touches a corpse; the rules of Is¬ lamism forbid dissection; and whatever their instructors taught was borrowed from the Greeks. Abu Bekr Al- Rasi, Abu-Ali Ibn-Sina, Abul-Casem, and Abu-Walid Ibn-Roschd, the Razes, Avicenna, Albucasis, and Aver- hoes of European authors, are their most celebrated names in medicine; yet to none of these can the histo¬ rian with justice ascribe any anatomical merit. Al-Rasi has indeed left descriptions of the eye, of the ear and its meatus, and of the heart; and Ibn-Sina, Abul-Casem, and Ebn-Roschd, give anatomical descriptions of the parts of the human body. But of these the general character is, that they are copies from Galen, sometimes not very just, and in all instances mystified with a large proportion of the fanciful and absurd imagery and inflated style of the Arabian writers. The chief reason of their obtaining a place in anatomical history is, that, by the influence which their medical authority enabled them to exercise in the European schools, the nomenclature which they employed was adopted by European anatomists, and con¬ tinued till the revival of ancient learning restored the ori¬ ginal nomenclature of the Greek physicians. Thus, the cervix, or nape of the neck, is nucha ; the oesophagus is meri; the umbilical region is sumen, or sumac; the ab¬ domen is myrach; the peritoneum is siphac; and the omentum, zirhus. From the general character now given, justice requires t>iat we except Abdollatiph, the annalist of Egyptian affairs. This author, who maintains that it is impossible to learn anatomy from books, and that the authority of Galen must yield to personal inspection, informs us, that the Moslem doctors did not neglect opportunities of studying the bones of the human body in cemeteries; and that he himself, by once examining a collection of bones in this manner, ascertained that the lower jaw is formed of one piece; that the sacrum, though sometimes com¬ posed of several, is most generally of one; and that Galen is mistaken when he asserts that these bones are not single. The era of Saracen learning extends to the 13th cen- Hist tury; and after this we begin to approach happier times, The university of Bologna, which, as a school of litera¬ ture and law, was already celebrated in the twelfth cen¬ tury, became, in the course of the following one, not less distinguished for its medical teachers. Though the 1222- misgovernment of the municipal rulers of Bologna had disgusted both teachers and students, and given rise to the foundation of similar institutions in Padua and Naples, —and though the school of Salerno, in the territory of the latter, was still in high repute,— it appears, from the 1241. testimony of Sarti, that medicine was in the highest esteem in Bologna, and that it was in such perfection as to re¬ quire a division of its professors into physicians, surgeons, physicians for wounds, barber-surgeons, oculists, and even some others. Notwithstanding these indications of re¬ finement, however, anatomy was manifestly cultivated rather as an appendage of surgery than a branch of medical science; and, according to the testimony of Guy de Chauliac, the cultivation of anatomical knowledge was confined to Roger, Roland, Jamerio, Bruno, and Lan- franc; and this they borrowed chiefly from Galen. For this and similar reasons, physicians were not in all in¬ stances respected by the best informed men of the age; and they fell, perhaps not altogether undeservedly, un¬ der the bitter lash of the satirical Petrarch. In this state matters appear to have proceeded with the medical school of Bologna till the commencement of the fourteenth century, when the circumstance of pos¬ sessing a teacher of originality enabled this university to be the agent of as great an improvement in medical science as she had already effected in jurisprudence. This era, indeed, is distinguished for the appearance of Mondino, under whose zealous cultivation the science first began to rise from the ashes in which it had been buried. This father of modern anatomy, who taught in Bologna about the year 1315, quickly drew the curiosity of the medical profession, by well-ordered demonstrations of the different parts of the human body. In 1315 he dissected and demonstrated the parts of the human body in two female subjects; and in the course of the follow¬ ing year he accomplished the same task on the person of a single female. But while he seems to have had suffi¬ cient original force of intellect to direct his own route, Riolan accuses him of copying Galen; and it is certain that his descriptions are corrupted by the barbarous leaven of the Arabian schools, and his Latin defaced by the exotic nomenclature of Ebn-Sina, and Abu-Bekr Al- Rasi. He died, according to Tiraboschi, in 1325. Mondino divides the body into three cavities (ventres), the upper containing the animal members, as the head, the lower containing the natural members, and the middle containing the spiritual'members. He first delivers the anatomy of the lower cavity or the abdomen, then proceeds to the middle or thoracic organs, and concludes with the upper, comprising the head, and its contents and append¬ ages. His general manner is to notice shortly the situa¬ tion and shape or distribution of textures or membranes, and then to mention the disorders to which they are subject. The peritoneum he describes under the name of siphac, in imitation of the Arabians, the omentum under that of zirhus, and the mesentery or eucharus as distinct from both. In speaking of the intestines, he treats first of the rectum, then the colon, the left or sigmoid flexure of which, as well as the transverse arch and its connec¬ tion with the stomach, he particularly remarks; then the caecum or monoculus, after this the small intestines m general under the heads of ileum and jejunum, and lattei- ly the duodenum, making in all six bowels.

His anatomy of the heart is wonderfully accu¬ rate; and it is a remarkable fact, which seems to be omitted by all subsequent authors, that his description contains the rudiments of the circulation of the blood. “ Postea vero versus pulmonem est aliud orificium venm arterialis, quas portal sanguinem ad pulmonem a corde; quia cum pulmo deserviat cordi secundum modum die- ♦ .if ^ * who described the two tympanal bones, termed malleus' and incus.

He mentions the orifices of the ducts afterwards described by Wharton.

In his account to calm the alarms of Europe, suffering under the ravages of the cerebral membranes, though short, he notices the of syphilis, then raging with uncontrollable virulence, "in principal characters of the dura mater. He describes shortly the lateral ventricles, with their anterior and pos¬ terior cornua, and the choroid plexus as a blood-red sub¬ stance, like a long worm. He then speaks of the third or middle ventricle, and one posterior, which seems to cor¬ respond with the fourth ; and describes the infundibulum under the names of lacuna and emboton. The inferior re¬ cesses he appears to have omitted. In the base of the organ he remarks, first, two mammillary caruncles, the ori¬ gins of the olfactory nerves, which, however, he overlooks; the optic nerves, which he reckons the first pair; the oculo-muscular, which he accounts the second ; the third, which appears to be the sixth of the moderns; the fourth; the fifth, evidently the seventh; a sixth, the nervus vagus ; and a seventh, which is the ninth of the moderns. Notwithstanding the misrepresentations into which this early anatomist was betrayed, his book is valuable, and the former character he surpassed both predecessors and contemporaries ; and it was long before the anatomists of the following age could boast of equalling him. His as¬ siduity was indefatigable; and he declares that he dis¬ sected above 100 human bodies. He is the author of a compendium, of several treatises which he names intro¬ ductions (IsagogeR), and of commentaries on the treatise of Mondino. Like him, he is tinged with the mysticism of the Arabian doctrines ; and though he employs the Grecian nomenclature in general, he never forgets to give the Arabian terms, and often uses them exclusively. In his commentaries on Mondino, which constitute the most perspicuous and complete of his works, he not only recti¬ fies the mistakes of that anatomist, but delivers minute and in general accurate anatomical descriptions. He is the first who undertakes a systematic view of the several textures of which the human body is compos- 1fs. illustrated by the successive commentaries of ed; and in a preliminary commentary he treats succes- Aclnlhm, Berenger, and Dryander. _ _ sively of the anatomical characters and properties of fat, Matthew de Gradibus, a native of Gradi, a town in of membrane in general (panniculus), of flesh, of nerve, Hmh, near Milan, distinguished himself by composing a o? villus or fibre Qilum), of ligament, of sinew or tendon, senes of tieatises on the anatomy ot various parts of the and of muscle in general.

He then describes the cavities of the heart; but perplexes him¬ self, as all the anatomists of that age, about the spirit supposed to be contained. The aorta he properly makes to arise from the left ventricle ; but confuses himself with the arteria venalis (pulmonary vein), and the vena ar- terialis, the pulmonary artery. His account of the brain is better. He gives a minute and clear account of the ventricles, remarks the corpus striatum, and has the saga¬ city to perceive that the choroid plexus consists of veins and arteries; he then describes the middle or third ven¬ tricle, the infundibulum or lacuna of Mondino, and the pituitary gland; and, lastly, the passage to the fourth ventricle, the conarium or pineal gland, and the fourth or posterior ventricle itself, the relations of which he had studied accurately. He rectifies the mistake of Mon¬ dino as to the olfactory or first pair of nerves, gives a good account of the optic and others, and is entitled to the praise of originality in being the first observer who con¬ tradicts the fiction of the wonderful net, and indicates the principal divisions of the carotid arteries. He enumerates the tunics and humours of the eye, and gives an account of the internal ear, in which he notices the malleus and incus. It had been written in the book of the destinies, that the science of anatomy was to be cultivated first in Italy ; and that the country, already so illustrious in literature, should be honoured in giving birth to the first eminent anatomists in Europe. This distinction she long retained ; and the glory she acquired in the names of Mondino, Achillini, Carpi, and Massa, was destined to become more conspicuous in the labours of Columbus, Fallopius, and Eustachius. While Italy, however, was thus advancing the progress of science, the other nations of Europe were either in profound ignorance or in the most supine indif¬ ference to the brilliant career of their zealous neighbours. The sixteenth century had commenced before France be¬ gan to acquire any anatomical distinction in the names of Dubois, Fernel, and Etienne; and even these celebrated teachers were less solicitous in the personal study of the animal body, than in the faithful explanation of the ana¬ tomical writings of Galen. The infancy of the French school had to contend with other difficulties. The small portion of knowledge which had been hitherto diffused in the country was so inadequate to eradicate the prejudices of ignorance, that it was either difficult or absolutely im¬ possible to procure human bodies for the purposes of science ; and we are assured, on the testimony of Vesa- lius and other competent authorities, that the practical part of anatomical instruction was obtained entirely from the bodies of the lower animals. The works of the Ita¬ lian anatomists were unknown ; and it is a proof of the tardy communication of knowledge, that while the struc¬ ture of the human body had been taught in Italy for more than a century by Mondino and his followers, they are never mentioned by Etienne, who flourished long after. Such was the aspect of the times at the appearance of Jacques Dubois, who, under the Romanized name of Jacobus Sylvius, according to the fashion of the day, has been fortunate in acquiring a reputation to which his re¬ searches do not entitle him. For the name of James Uubois, the history of anatomy, it is said, is indebted to his inordinate love of money. At the instance of his brother hrancis, who was professor of eloquence in the Go ege of lournay at Paris, he repaired to this university, and devoted himself to the study of the learned languages and mathematics; but discovering that these elegant ac¬ complishments do not invariably reward their cultivators with the goods of fortune, Dubois betook himself to me- Hi ny. dicine. After the acquisition of a medical degree in the^iv. university of Montpellier, at the ripe age of fifty-one Dubois returned to Paris to resume a course of anatomi¬ cal instructions which had been interrupted by the cano¬ nical interference of the medical faculty. Here he taught anatomy to a numerous audience in the college of Trin- quet; and, on the departure of Vidus Vidius for Italy, was appointed to succeed that physician as professor of surgery to the Royal College. His character is easily es¬ timated. With a greater portion of coarseness in his manners and language than even the rude state of so¬ ciety can palliate, with much varied learning and consider¬ able eloquence, he was a blind, indiscriminate, and irra¬ tional admirer of Galen, and interpreted the anatomical and physiological writings of that author, in preference to giving demonstrations from the subject. Without talent for original research or discovery himself, his envy and jealousy made him detest every one who gave proofs of either. We are assured by Vesalius, who was some time his pupil, that his manner of teaching was calculated nei¬ ther to advance the science nor to rectify the mistakes of his predecessors. A human body was never seen in the theatre of Dubois; the carcasses of dogs and other ani¬ mals were the materials from which he taught; and so difficult even was it to obtain human bones, that unless Vesalius and his fellow-students had collected assiduously from the Innocents and other cemeteries, they must have committed numerous errors in acquiring the first princi¬ ples. This assertion, however, is contradicted by Riolan, and more recently by Sprengel and Lauth, the last of whom decidedly censures Vesalius for this ungrateful treatment of his instructor. It is certain that opportuni¬ ties of inspecting the human body were by no means so frequent as to facilitate the study of the science. Though his mention of injections has made him be thought the discoverer of that art, he appears to have made no sub¬ stantial addition to the information already acquired; and the first acknowledged professor of anatomy to the uni¬ versity of Paris appears in history as one who lived with¬ out true honour, and died without just celebrity. He must not be confounded with Franciscus Sylvius (De le Boe), who is mentioned by Ruysch and Malacarne as the author of a particular method of demonstrating the brain. Almost coeval may be placed Charles Etienne, a younger 1503- ■ brother of the celebrated printers, and son to Henry, who Hellenized the family name by the classical appellation of Stephen (Srspavo;). It is uncertain whether he taught publicly. But his tranquillity was disturbed, and his pursuits interrupted, by the oppressive persecutions in which their religious opinions involved the family; and Charles Etienne drew the last breath of a miserable life in a dungeon in 1564. Etienne, though sprung of a family whose classical taste has been their principal gloryj be¬ trays not the same servile imitation of the Galenian ana¬ tomy with which Dubois is charged, and is the first ana¬ tomical author who deviates from the beaten path. He ap¬ pears to have been the first to detect valves in the orifice of the hepatic veins. He was ignorant, however, of the re¬ searches of the Italian anatomists ; and his description of the brain is inferior to that given 60 years before by Achil¬ lini. His comparison of the cerebral cavities to the hu¬ man ear has persuaded Portal that he knew the inferior cornua, and hippocampus, and its prolongations; but this is no reason for giving him that honour, to the detriment of the reputation of Achillini, to whom, so far as histori¬ cal testimony goes, the first knowledge of this fact is due. The researches of Etienne into the structure of the ner- ANATOMY. Ui5 y. vous system are, however, neither useless nor inglorious ; the circumstance of demonstrating a canal through the entire length of the spinal chord, which had neither been suspected by contemporaries nor noticed by succes¬ sors, till M. Senac made it known, is sufficient to place him high among the class of anatomical discoverers. The French anatomy of the sixteenth century was dis¬ tinguished by two circumstances unfavourable to the ad¬ vancement of the science,—extravagant admiration of an¬ tiquity, with excessive confidence in the writings of Galen, and the general practice of dissecting principally the bodies of the lower animals. Both of these errors were much amended, if not entirely removed, by the exertions of a young Fleming, whose appearance forms a conspicu- i;. ous era in the history of cerebral anatomy. Andrew Ve- salius, a native of Brussels, after acquiring at Louvain the ordinary classical attainments of the day, began, at the age of 14, to study anatomy under the auspices of Dubois. Though the originality of his mind soon led him to aban¬ don the prejudices by which he was environed, and take the most direct course for attaining a knowledge of the structure of the human frame; yet he neither underrated the Galenian anatomy, nor was he indolent in the dissec¬ tion of brute animals. The difficulties, however, with which the practical pursuit of human anatomy was be¬ set in France, and the dangers with which he had to contend, made him look to Italy as a suitable field for the cultivation of the science ; and in 1536 we find him at Venice, at once pursuing the study of human ana¬ tomy with the utmost zeal, and requested, ere he had at¬ tained his 22d year, to demonstrate publicly in the uni¬ versity of Padua. After remaining here about seven years, he went by express invitation to Bologna, and shortly afterwards to Pisa; and Vesalius, thus professor in three universities, appears to have carried on his ana¬ tomical investigations and instructions alternately at Pa¬ dua, Bologna, and Pisa, in the course of the same win¬ ter. It is on this account that Vesalius, though a Flem¬ ing by birth, and trained originally in the French school, belongs, as an anatomist, to the Italian, and may be view¬ ed as the first of an illustrious line of teachers by whom the anatomical reputation of that country was in the course of the sixteenth century raised to the greatest eminence. Vesalius is known as the first author of a comprehen¬ sive and systematic view of human anatomy. The know¬ ledge with which his dissections had furnished him, proved how many errors were daily taught and learned under the broad mantle of Galenian authority; and he perceived the necessity of a new system of anatomical instruction, divested of the omissions of ignorance and the misrepre¬ sentations of prejudice and fancy. The early age at which he effected this object has been to his biogra¬ phers the theme of boundless commendations ; and we are told that he began at the age of 25 to arrange the mate¬ rials he had collected, and accomplished his task ere he l*ad completed his 28th year. Soon after this period we find him invited as imperial physician to the court of Charles V., where he was occu¬ pied in the duties of practice, and answering the various charges which were unceasingly brought against him by the Galenian disciples. After the abdication of Charles, he continued at court in great favour with his son Philip tk To this he seems to have been led principally by the jroublesome controversies in which his anatomical writ- •ngs had involved him. It is painful to think, however, 695 History- barism of the times, and of the precarious tenure of the safety even of a great physician. On the preliminary cir¬ cumstances authors are not agreed ; but the most gene¬ ral account states, that when Vesalius was inspecting, with the consent of his kinsmen, the body of a Spanish^ gran¬ dee, it was observed that the heart still gave some feeble palpitations when divided by the knife. ' The immediate effects of this outrage to human feeling were to denounce the anatomist to the inquisition; and Vesalius escaped the merciful dispensations of this tribunal only by the in¬ fluence of the king, and by promising to perform a pil¬ grimage to the Holy Land. He forthwith proceeded to Venice, from which he sailed with the Venetian fleet, un¬ der James Malatesta, for Cyprus. When he reached Je¬ rusalem, he received from the Venetian senate a message requesting him again to accept the Paduan professorship, which had become vacant by the death of his friend and pupil Fallopius. His destiny, however, which pursued 15G4. him fast, suffered him not again to breathe the Italian air. After struggling for many days with adverse winds in the Ionian Sea, he was wrecked on the island of Zante, where he quickly breathed his last in such penury, that unless a liberal goldsmith had defrayed the funeral charges, his carcass must have been devoured by beasts of prey. At the time of his death he was scarcely 50 years of age. To form a correct estimate of the character and merits of Vesalius, we must not compare him, in the spirit of mo¬ dern perfection, with the anatomical authors either of later times or of the present day. Whoever would frame a just idea of this anatomist, must imagine himself living in the days of Charles V., when learning did not uniform¬ ly liberalize,—when the rekindling light of ancient times shone on nothing but its own glories,—when education consisted in the knowledge of ancient opinions, and the au¬ thority of Grecian and Roman names usurped in the tem¬ ple of science the legitimate worship of nature. He must imagine, not a bold innovator without academical learning,—not a genius coming from a foreign country, unused to the forms and habits of Catholic Europe,—nor a wild reformer, blaming indiscriminately every thing which accorded not with his opinions ;—but a young stu¬ dent scarcely emancipated from the authority of instruc¬ tors, and whose intellect was still influenced by the doctrines with which it had been originally imbued,—an individual strictly trained in the opinions of the time, living amidst men who venerated Galen as the oracle of anatomy and the divinity of medicine,—exercising his reason to esti¬ mate the soundness of the instructions then in use, and proceeding, in the way least likely to offend authority and wound prejudice, to rectify errors, and to establish on the solid basis of observation the true elements of anatomical science. Vesalius has been denominated the founder of human anatomy; and though we have seen that in this career he was preceded with honour by Mondino and Be- renger, still the small proportion of correct observation which their reverence for Galen and Arabesque doctrines allowed them to communicate, will not in a material de¬ gree impair the original merits of Vesalius. The errors which he rectified, and the additions which he made, are so numerous, that it is impossible, in such a sketch as the present, to communicate a just idea of them. Besides the first good description of the sphenoid bone, he showed that the sternum consists of three portions, and the sacrum of five or six; and described accurately the vestibule in the interior of the temporal bone. He not only verified the observation of Etienne on the valves lat even imperial patronage bestowed on eminent talents of the hepatic veins, but he described well the vena azy- Goes not insure immunity from popular prejudice; and gos, and discovered the canal which passes in the foetus le fate of Vesalius will be a lasting example of the bar- between the umbilical vein and the vena cava, since nam* 696 ANATOMY. History, ed ductus venosus. He described the omentum, and its connections with the stomach, the spleen, and the colon; gave the first correct views of the structure of the pylo¬ rus ; remarked the small size of the csecal appendix in man ; gave the first good account of the mediastinum and pleura, and the fullest description of the anatomy of the brain yet advanced. He appears, however, not to have understood well the inferior recesses; and his account of the nerves is confused by regarding the optic as the first pair, the third as the fifth, and the fifth as the seventh. The labours of Vesalius were not limited to the imme¬ diate effect produced by his own writings. His instruc¬ tions and example produced a multitude of anatomical inquirers of different characters and varied celebrity, but by whom the science was extended and rectified. Of these it belongs not to this place to speak in detail; but historical justice requires us to notice shortly those towhose exertions the science of anatomy has been most indebted. 1 ins or The first that claims attention on this account is Bar- 1500. tholomeo Eustachi of San Severino, near Salerno, who though greatly less fortunate in reputation than Vesalius, divides with him the merit of creating the science of human anatomy. He extended the knowledge of the in¬ ternal ear, by re-discovering and describing correctly the tube which bears his name; and if we admit that Ingras- sias anticipated him in the knowledge of the third bone of the tympanal cavity, the stapes, he is still the first who described the internal and anterior muscles of the malleus, as also the stapedius, and the complicated figure of the cochlea. He is the first who studied accurately the ana¬ tomy of the teeth, and the phenomena of the first and second dentition. The work, however, which demon¬ strates at once the great merit and the unhappy fate of Eustachius, is his Anatomical Engravings, which, though completed in 1552, nine years after the impression of the work of Vesalius, the author was unable to publish. First communicated to the world in 1714 by Lancisi, af¬ terwards in 1740 by Cajetan Petrioli, again in 1744 by Albinus, and more recently at Bonn, in 1790, they show that Eustachius had dissected with the greatest care and diligence, and taken the utmost pains to give just views of the shape, size, and relative position of the organs of the human body. The first seven plates illustrate the history of the kid¬ neys, and some of the facts relating to the structure of the ear. The eighth represents the heart, the ramifica¬ tions of the vena azygos, and the valve of the vena cava, named from the author. In the seven subsequent plates is given a succession of different views of the viscera of the chest and abdomen. The seventeenth contains the brain and spinal chord; and the eighteenth more accurate views of the origin, course, and distribution of the nerves than were then given. Fourteen plates are devoted to the muscles. Eustachius did not confine his researches to the study of relative anatomy. He investigated the intimate struc¬ ture of organs with assiduity and success. What was too minute for unassisted vision he inspected by means of glasses. Structure, which could not be understood in the recent state, he unfolded by maceration in different fluids, or rendered more distinct by injection and exsiccation. The facts unfolded in these figures are so important, that it is justly remarked by Lauth, that if the author himself had been fortunate enough to publish them, anatomy would have attained the perfection of the 18th century two centuries earlier at least. Their seclusion for that penod m the papal library has given celebrity to many names, which would have been known only in the verifi¬ cation of the discoveries of Eustachius. r Eustachius was the contemporary of Vesalius. Colum* ipU- bus and Fallopius were his pupils. The former, as his^-H/ immediate successor in Padua, and afterwards as profes¬ sor at Rome, distinguished himself by rectifying and im¬ proving the anatomy of the bones; by giving correct ac¬ counts of the shape and cavities of the heart, of the pul¬ monary artery and aorta, and their valves, and tracing the course of the blood from the right to the left side of the heart; by a good description of the brain and its vessels, and by correct understanding of the internal ear, and the first good account of the ventricles of the larynx. The latter, who after being professor at Pisa in 1548, and at Padua in 1551, died at the age of 40, studied the general anatomy of the bones; described better than heretofore the internal ear, especially the tympanum and its osseous ring, the two fenestrce, and their communication with the vestibule and cochlea; and gave the first good account of the stylo-mastoid hole and canal, of the ethmoid hone and cells, and of the lacrymal passages. In myology he recti¬ fied several mistakes of Vesalius. He made some curiou^ researches into the organs of generation in both sexes, and discovered the utero-peritoneal canal which still bears his name. Osteology nearly at the same time found an assiduous 1511 cultivator in John Philip Ingrassias, a learned Sicilian 80. physician, who, in a skilful commentary on the osteology of Galen, corrected numerous mistakes. He gave the first distinct account of the true configuration of the sphenoid and ethmoid bones, and has the merit of first describing the third bone of the tympanum, called stapes, 154( though this is also claimed by Eustachius and Fallopius. He appears also to have known the fenestrce, the chorda tympani, the cochlea, the semi-circular canals, and the mastoid cells. The anatomical descriptions of Vesalius underwent thei53C scrutiny of various inquirers, actuated, some by motives of hostility to the individual, others by the more honourable wish to ascertain if his representations accorded with nature. Of the latter, Fallopius was one; but the most distinguished by the importance and veracity of their re¬ searches, as well as the temperate tone of their observa¬ tions, were Julius Caesar Aranzi, anatomical professor for 32 years in the university of Bologna, and Constantio Varoli, physician to Pope Gregory XJII. To the former we are indebted for the first correct account of the ana¬ tomical peculiarities of the foetus, and for being the first to show that the muscles of the eye do not, as was falsely imagined, arise from the dura mater, but from the margin of the optic hole. He also, after considering the anatomi¬ cal relations of the cavities of the heart, the valves, and the great vessels, corroborates the views of Columbus re¬ garding the course which the blood follows in passing from the right to the left side of the heart. I have al¬ ready mentioned Alexander Achillini as the reputed and probable discoverer of the inferior recesses of the cerebral cavities ; but whether he knew them or not, certain it is that neither his contemporaries nor successors gave any proof that they were acquainted with these regions of the brain. Aranzi is the first anatomist who describes them distinctly, who recognises the objects by which they are distinguished, and who gives them the name by which they are still known (bombyx, hippocampus); and his account is more minute and perspicuous than that 0 the authors of the subsequent century. He speaks at large of the choroid plexus, and gives a particular descrip¬ tion of the fourth ventricle under the name of cistern of the cerebellum, as a discovery of his own. , Italy, though rich in anatomical talent, has producec 0 0 probably none greater than Constantio Varoli of Bologna- ANATOMY. Hi >ry. Though limited in the measure of his existence to the short space of 32 years, he acquired reputation not inferior to that of the most eminent of his contemporaries. He is now known chiefly as the author of an Epistle, inscribed to Hieronymo Mercuriali, on the optic nerves, in which he describes a new method of dissecting the brain, and com¬ municates many interesting particulars relating to the ana¬ tomy of the organ. Overlooking the fanciful comparison of the transverse eminence and the prolongations (crura) of the brain and cerebellum to a bridge over the water of an aqueduct, though he examines the lower surface of the organ with tedious minuteness, he gives evidence that he formed a more accurate and just idea of its configuration than any of the best modern anatomists. He observes the threefold division of the inferior surface or base, defines the limits of the anterior, middle, and posterior eminences, as marked by the compartments of the scull, and justly remarks that the cerebral cavities are capacious, commu¬ nicate with each other, extending first backward and then forward, near the angle of the pyramidal portion of the temporal bone, and that they are folded on themselves, and finally lost above the middle and inferior eminence of the brain. He appears to have been aware that at this point they communicate with the exterior or convoluted surface. He recognised the impropriety of the term cor¬ pus callosum, seems to have known the communication, called afterwards foramen Monroianum, and describes the hippocampus more minutely than had been previously done. Among the anatomists of the Italian school, as a pupil of Fallopius, Eustachius, and Aldrovandus, is generally enumerated Volcher Goiter of Groningen. He dis¬ tinguished himself by accurate researches on the cartilages, the bones, and the nerves, recognised the value of morbid anatomy, and made some experiments on living animals to ascertain the action of the heart and the influence of the brain. The Frutefull and Necessary Briefe Worhe of John Halle (1565), and The Englishemans Treasure, by Master Thomas Vicary (1586), both English works published at this time, are tolerable compilations, partly from Be- renger, partly from Vesalius, and much tinged by the ualenian and Arabian distinctions. ' - The celebrity of the anatomical school of Italy was worthily maintained by Hieronymo Fabricio of Aqua- pendente, who, in imitation of his master Fallopius, laboured to render anatomical knowledge more precise by repeated dissections, and to illustrate the obscure by researches on the structure of animals in general. In this manner he investigated the formation of the foetus, the structure of the oesophagus, stomach, and bowels, and the peculiarities of the eye, the ear, and the larynx. The dis- 697 mi covery, however, on which his surest claims to eminence History, rest, is. that of the membranous fbldsj which he names'1 valves, in the interior of veins. Several of these folds had been observed by Femel, Sylvius, and Vesalius; and in 1547 Cannani observed those of the vena azygos ; but no one appears to have offered any rational conjecture on their use, or to have traced them through the venous sys¬ tem at large, until Fabricius in 1574, upon this hypothesis, demonstrated the presence of these valvular folds in all the veins of the extremities. Fabricius, though succeeded by his pupil Julius Casserius of Piacenza, may be regarded as the last of that illustrious line of anatomical teachers by whom the science was so successfully studied and taught in the universities of Italy. The discoveries which each made, and the errors which their successive labours rectified, tended gradually to give anatomy the character of a useful as well as an accurate science, and to pave the way for a discovery which, though not anatomical, but physiological, is so intimately connect¬ ed with correct knowledge of the shape and situation of parts, that it exercised the most powerful influence on the future progress of anatomical inquiry. This was the knowledge of the circular motion of the blood,—a fact which, though obscurely conjectured by Aristotle, Mon- dino, and Berenger, and partially taught by Servetus, Co¬ lumbus, Cassalpinus, and Fabricius, it^was nevertheless re¬ served to William Harvey fully and satisfactorily to de¬ monstrate. I have already shown that Mondino believed that the blood proceeds from the heart to the lungs, through the vena arterialis or pulmonary artery, and that the aorta conveys the spirit into the blood, through all parts of the body. This doctrine was adopted with little mo¬ dification by Berenger, who further demonstrated the existence and operation of the tricuspid valves in the right ventricle, and of the sigmoid valves at the beginning of the pulmonary artery and aorta, and that there were only two ventricles separated by a solid impervious sep¬ tum. These were afterwards described in greater de¬ tail by Vesalius, who nevertheless appears not to have been aware of the important use which might be made of this knowledge. It was Michael Servet or Servetus,1 a Spanish monk, who in his treatise de Trinitatis Er- rorihus, published at Basil in 1531, or, according to Sprengel, in 1552, first maintained the imperviousness of the septum, and the transition of the blood by what he terms an unknown route, namely, from the right ven¬ tricle by the vena arteriosa (pulmonary artery) to the lungs, and thence into the arteria venosa or pulmonary vein, and left auricle and ventricle, from which, he adds afterwards, it is conveyed by the aorta to all parts of the body.2 1 hough the leading outlines, not only of the pulmonary 1 Horn in 1509; burnt in 1553. auJ1!6 P®ss?£® ‘'erv?tus 18 80 interesting, that our readers may feel some curiosity in perusing it in the language of the the <1pb’v "'c \S •n.°t unimPortant to remark, that Servetus appears to have been led to think of the course of the blood, bv ventr- ‘if 0 exP npnng the manner in which the animal spirits were supposed to be generated. “ Vitalis spiritus in sinistro cordis tus fliv ° 811:1111 yiiginem habet, juvantibus maxime pulmonibus ad ipsius perfectionem.

VOL. II. vi/ 4 X 698 ANATOMY. History, or small, but even of the great circulation, were sketched thus early by one who, though a philosopher, was attached to the church, it was only in his work De Re Anatomica, published at Venice in 1559, that Columbus formally and distinctly announced the circular course of the blood as a discovery of his own; and maintained, in addition to the imperviousness of the septum, the fact that the arteria ve- nalis (pulmonary vein) contains not air, but blood mixed with air brought from the lungs to the left ventricle of the heart, to be distributed through the body at large. 1570-1593. Soon after, views still more complete of the small or pulmonary circulation were given by Andrew Caesalpinus of Arezzo, who not only maintained the analogy between the structure of the arterious vein or pulmonary artery and the aorta, and that between the venous artery or pul¬ monary veins, and veins in general, but was the first to remark the swelling of veins below ligatures, and to infer from it a refluent motion of blood in these vessels. The discoveries of Aranzi and Eustachius in the vessels of the foetus, tended at first to perplex, and afterwards to eluci¬ date some of these notions. At length it happened, that between the years 1598 and 1600, a young Englishman, pursuing his anatomical studies at Padua under Fabricius of Aquapendente, learnt from that anatomist the existence of the valves in the veins of the extremities, and under¬ took to ascertain the use of these valves by experimental inquiry. It is uncertain whether he learnt from the writ¬ ings of Caesalpinus the fact observed by that author, of the tumescence of a vein below the ligature; but he could not fail to be aware, and indeed he shows that he was aware, of the small circulation as taught by Servetus and Columbus. Combining these facts already known, he, by a series of well-executed experiments, demonstrated clearly the existence, not only of the small, but of a gene¬ ral circulation from the left side of the heart by the aorta and its subdivisions, to the right side by the veins. This memorable truth was first announced in the year 1619. It belongs not to this place, either to consider the argu¬ ments and facts by which Harvey defended his theory, or to notice the numerous assaults to which he was exposed, and the controversies in which his opponents wished to involve him. It is sufficient to say, that after the temporary ebullitions of spleen and envy had subsided, the doctrine of the circular motion of the blood was admitted by all enlightened and unprejudiced persons, and finally was universally adopted, as affording the most satisfactory explanation of many facts in anatomical structure which were either misunderstood or entirely overlooked. The inquiries to which the investigation of the doctrine gave rise produced numerous researches on the shape and structure of the heart and its divisions, of the lungs, and of the blood-vessels and their distribution. Of this de¬ scription were the researches of Nicolas Steno on the struc¬ ture of the heart, the classical work of Richard Lower, the dissertation of Pechlin, the treatise of Vieussens, the work of Malpighi on the structure of the lungs, several sketches in the writings of Mayow, and other treatises of less moment. Systematic treatises of anatomy began to assume a more instructive form, and to breathe a more philosophical spirit. The great work of Adrian Spigelius, which appeared in 1627, two years after the death of the author, contains indeed no proof that he was aware of the valuable generalization of Harvey; but in the in¬ stitutions of Caspar Bartholin, as republished and improv¬ ed by his son Thomas in 1651, the anatomical descriptions and explanations are given with reference to the new doc¬ trine. A still more unequivocal proof of the progress of correct anatomical knowledge was given in the lectures delivered by Peter Dionis, at the Jardin Royal of Paris, in 1673 and the seven following years, in which that in- f torr telligent surgeon gave most accurate demonstrations oT-.Vn all the parts composing the human frame, and especially of the heart, its auricles, ventricles, and valves, and the large vessels connected with it and the lungs. These demonstrations, first published in 1690, were so much esteemed, that they underwent in the space of 30 years seven editions, were translated into English, and formed for a long time the best and only anatomical system in Europe. The progress of anatomical discovery continued in the mean time to advance. In the course of the 16th century, Eustachius, in studying minutely the structure of the vena azygos, had recognised in the horse a white vessel full of watery fluid, connected with the internal jugular vein, on the left side of the vertebral column, correspond¬ ing accurately with the vessel since named thoracic duct Fallopius also described vessels belonging to the liver, distinct from arteries and veins; and similar vessels ap¬ pear to have been noticed by Nicolaus Massa. The nature and properties of these vessels were, however, en¬ tirely unknown. On the 23d July 1622 Gaspar Asellius, professor of anatomy at Pavia, while engaged in demon¬ strating the recurrent nerves in a living dog, first observ¬ ed numerous white delicate filaments crossing the me¬ sentery in all directions ; and though he took them at first for nerves, the opaque white fluid which they shed quick¬ ly convinced him that they were a new order of ves¬ sels. The repetition of the experiment the following day showed that these vessels were best seen in animals re¬ cently fed; and as he traced them from the villous mem¬ brane of the intestines, and observed the valves with which they were liberally supplied, he inferred that they wTere genuine chyliferous vessels. By confounding them with the lymphatics, he made them proceed to the pan¬ creas and liver,—a mistake which appears to have been first rectified by Francis De le Boe. The discovery of Asellius was announced in 1627 ; and the following year, by means of the zealous efforts of Nicolas Peiresc, a li¬ beral senator of Aix, the vessels were seen in the person of a felon who had eaten copiously before execution, and whose body was inspected an hour and a half after. In 1629 they were publicly demonstrated at Copenhagen by Simon Pauli, and the same year the thoracic duct was ob¬ served by Mentel for the first time since it was described by Eustachi. Five years after (1634), John Wesling, professor of anatomy and surgery at Venice, gave the first delineation of the lacteals from the human subject, and evinced more accurate knowledge than his predeces¬ sors, of the thoracic duct and the lymphatics. Highmore in 1637 demonstrated unequivocally the difference be¬ tween the lacteals and the mesenteric veins; and though some perplexity was occasioned by the discovery of the pancreatic duct by Wirsung, yet this mistake was correct¬ ed by Thomas Bartholin; and the discovery by Pecquet in 1647, of the common trunk of the lacteals and lympha¬ tics, and of the course which the chyle follows to reach the blood, may be regarded as the last of the series of iso¬ lated facts by the generalization of which the extent, dis¬ tribution, and uses of the most important organs of the animal body were at length developed. . . To complete the history of this part of anatomica science one step yet remained,—the distinction between the lacteals and lymphatics, and the discovery of the ter mination of the latter order of vessels. Ihe honour o this discovery is divided between Jolyffe, an English ana tomist, and Olaus Rudbeck, a young Swede. The former. according to the testimony of Glisson and Wharton,^8 aware of the distinct existence of the lymphatics m ANATOMY. Histor and demonstrated them as such in 1652. It is neverthe- /Y^less doubtful whether he knew them much before the latter period; and it is certain that Rudbeck observed the lymphatics of the large intestines, and traced them to glands, on the 27th January 1651, after he had, in the course of 1650, made various erroneous conjectures re¬ garding them, and, like others, attempted to trace them to the liver. The following year he demonstrated them in presence of Queen Christina, and traced them to the thoracic duct, and the latter to the subclavian vein. Their course and distribution were still more fully investigated by Thomas Bartholin, Wharton, Swammerdam, and Blaes, the two last of whom recognised the existence of valves ; while Antony Nuck of Leyden, by rectifying various er¬ rors of his predecessors, and adding several new and va¬ luable observations, rendered this part of anatomy much more precise than formerly. After this period anatomists began to study more ac¬ curately organs and textures already known, and to obtain more precise knowledge of the intimate structure and or- 1654, ganization of the human body. Francis Glisson distin¬ guished himself by a minute description of the liver, and a clearer account of the stomach and intestines than IG-ji; had yet been given. Thomas Wharton investigated the structure of the glands with particular care ; and though rather prone to indulge in fanciful generalization, he deve¬ loped some interesting views of these organs ; while Charle- ton, who appears to have been a person of great genius, though addicted to hypothesis, made some good remarks on the communication of the arteries with the veins, the foe¬ tal circulation, and the course of the lymphatics. But the circumstance which chiefly distinguished the history of anatomy at the beginning of the seventeenth century, was the appearance of Thomas Willis, who rendered him¬ self eminent not only by the first good researches on the brain and nerves, but by many judicious observations on the structure of the lungs, the intestines, the blood-ves¬ sels, and the glands. His anatomy of the brain and nerves is so minute and elaborate, and abounds so much in new information, that the reader is struck by the im¬ mense chasm between the vague and meagre notices of his predecessors, and the ample and correct descrip¬ tions of Willis. This excellent work, however, is not the result of his own personal and unaided exertions; and the character of Willis derives additional lustre from the candid avowal of his obligations to Wren and Millington, and, above all, to the diligent researches of his fellow- anatomist Richard Lowrer. Willis was the first who correctly numbered the nerves, and described their origins in the order in which they have been generally named till the recent improvements of Soem- menng. His observation of the connection of the eighth pair with the slender nerve which issues from the beginning of the spinal chord is known to all. He remarked the paral¬ lel lines of the mesolobe, afterwards minutely described by \‘cq d’Azyr. He seems to have recognised the commu¬ nication of the convoluted and figurate surfaces of the brain, and that between the lateral cavities beneath the (<)rnix. He designates the objects of the central surface— fhe anterior as the lentiform eminences, with the striated appearance of their internal substance—the posterior as 6 optic chambers or thalami; the four orbicular emi¬ nences, with the bridge, which he first named annular protuberance; and the white pisiform bodies, since called mammillary eminences, behind the infundibulum. In e cerebellum he remarks the arborescent arrangement 0 the white and grey matter, and gives a good account “ the internal carotids, and the communications which “^ymake with the branches of the basilar artery. Wep- 699 fer had already demonstrated the peculiar curvature of History, the former vessels in the carotic canal, and refuted the fiction of the rete mirabile. About the same time the researches of Malpighi tended greatly to improve the knowledge of minute struc- ture. Fie gave the first distinct ideas on the organization of the lung, and the mode in wLich the bronchial tubes and vessels terminate in that organ. By the microscope he traced the transition of the arteries into the veins. He examined the omentum, and inquired into the manner in which fat and marrow are secreted. He endeavoured to unfold, by dissection and microscopic observation, the minute structure of the brain. He demonstrated the or¬ ganization of the skin, and considered its constituents as the organ of touch. He studied the structure of bone, and rectified the errors of Gagliardi; he traced the for¬ mation and explained the structure of the teeth; and he finally carried his researches into the substance of the liver, the spleen, the kidneys, and the conglobate glands. In these difficult inquiries the observations of Malpighi are in general faithful, and his descriptions are accurate. He may be regarded as the founder of that part of anatomical science which treats of structure and organization; and, even in the present day, his writings are both interesting and instructive. Nicolas Steno described with accuracy the lacrymal 1GG0. gland and passages, and re-discovered the parotid duct. Bellini studied the structure of the kidneys, and de¬ scribed the tongue and tonsils with some care; and Drelincourt laboured to investigate the changes effect¬ ed on the uterus by impregnation, and to elucidate the formation of the foetus. The science might have derived still greater advantages from the genius of Regnier de Graaf, who investigated with accuracy the structure of the pancreas and of the organs of generation in both sexes, had he not been cut off at the early age of 32. Lastly, Wepfer, though more devoted to morbid ana¬ tomy, made, nevertheless, some just observations on the anatomical disposition of the cerebral vessels, the glandular structure of the liver, and the termination of the common duct in the duodenum. The appearance of Frederic Ruysch, who was born in 1638, and became professor of anatomy at Amsterdam in 1665, gave a new impulse to anatomical research, and tended not only to give the science greater precision, but to extend its limits in every direction. The talents of Ruysch are said to have been developed by accident. To repel the audacious and calumnious aspersions with which De Bils attacked De le Boe and Van Horne, Ruysch pub¬ lished his tract on the valves of the lymphatics, which com¬ pletely established his character as an anatomist of origin¬ ality and research. This, however, is the smallest of his services to the science. The art of injecting, which had been originally attempted by Eustachi and Varoli, and was afterwards rudely practised by Glisson, Bellini, and Willis, was at length carried to greater perfection by De Graaf and Swammerdam, the former of whom injected the spermatic vessels with mercury and variously colour¬ ed liquors, while the latter, by employing melted wax with other ingredients, made the first approach to the refine¬ ments of modern anatomy. By improving this idea of using substances, which, though solid, may be rendered fluid at the period of injecting, Ruysch carried this art to the highest perfection. By the application of this happy contrivance, he was enabled to obtain more correct views than his predeces¬ sors of the arrangement of minute vessels in the interior of organs, and to demonstrate peculiarities of organization which escaped the scrutiny of previous anatomists. Scarce- ANATOMY. 700 History, ly a part of the human body eluded the penetration of his syringe; and his discoveries were proportionally great. His account of the valves of the lymphatics, of the vessels of the lungs, and their minute structure; his researches on the vascular structure of the skin, of the bones, and their epiphyses, and their mode of growth and union; his ob¬ servations on the spleen, the glans penis, the clitoris, and the womb impregnated and unimpregnated, were suffi¬ cient to give him the reputation of a skilful and accurate anatomist. These, however, were but a limited part of his anatomical labours. He studied the minute structure of the brain; he demonstrated the organization of the choroid plexus; he described the state of the hair when affected with Polish plait; he proved the vascular struc¬ ture of the teeth ; he injected the dura mater, the pleura, the pericardium, and peritoneum ; he unfolded the minute structure of the conglomerate glands; he investigated that of the synovial apparatus placed in the interior of the joints ; and he discovered several curious particulars relating to the lacteals, the lymphatics, and the lymphatic glands. So assiduously, indeed, did Ruysch study by in¬ jection the tissue of the organs of the animal body, that it is less easy to say what he did than what he neglected. To him we are indebted for many of the facts of which anatomy at the present day consists. The success of his injections, however, though it enabled him to trace the most delicate terminations of vessels in the substance of organs, perhaps exercised an unfavourable bias in making him look for vessels exclusively in the minute structure of all the tissues. 1G70. Meanwhile, Meibomius re-discovered the palpebral glands, which were known to Casserius; Swammerdam studied the action of the lungs, described the structure of the human uterus, and made numerous valuable obser¬ vations on the caeca and pancreatoid organs of fishes ; and Kerckringius attempted to explain the process of ossifica¬ tion, and determine its different stages. John Conrad Brun- 1G87. ner, in the course of experiments on the pancreas, disco¬ vered the muciparous glands of the duodenum,—a fact to 1677-81. which Conrad Peyer gave a more generalized character by his description of the muciparous glands of the intes¬ tinal canal at large. Leonard Tassin, distinguished for original observation, rendered the anatomical history of the brain more accurate than heretofore, and gave parti- 1G73. cular accounts of the intestinal tube, the pancreatic duct, and the hepatic ligaments. About the same time much light was thrown on the intimate constitution of several of the tissues, and on the minute communications of the arterial and venous tubes by the microscopical observations of Leeuwenhoeck. That France might not be without participation in the glory of advancing the progress of anatomical knowledge, the names of Duverney and Yieussens are commemorated with distinction. The former, born in 1648, and first in¬ troduced into public life in 1676 in the Royal Academy of Sciences, decorated with the honorary title of profes¬ sor of anatomy to the Dauphin, and appointed in 1679 professor at the Jardin Royal, distinguished himself by the first accurate account of the organ of hearing, and by his dissections of several animals at the academy, supplied valuable materials for the anatomical details of the natural history of animals published by that learned body. He appears to have been the first who demonstrat¬ ed the fact, that the cerebral sinuses open into the jugu¬ lar veins, and to have been aware that the former receive the veins of the brain, and are the venous receptacles of the organ. He understood the cerebral cavities, and their mode of communication; distinguishes the posterior pil¬ lars of the vault from the pedes hippocampi; recognises the two plates of the septum lucidum; and, what is still storv more remarkable, he first indicates distinctly the crossing's vx! or plaiting of the cerebral chords in the linear furrow be¬ tween the right and left pyramidal bodies,—a fact after¬ wards verified by the researches of Mistichelli, Petit, and Santorini. He studied the ganglions attentively, and gives the first distinct account of the formation, con¬ nections, and distribution of the intercostal nerve. It is interesting to remark, that his statement that the veins or sinuses of the spinal chord terminate in the vena azygos has been verified by the recent researches of Dupuytren and Breschet, which show that the vertebral veins com¬ municate by means of the intercostal and superior lumbar veins with the azygos and demi-azygos. His account of the structure of bones, and of the progress of ossification, is valuable. He recognised the vascular structure of the spleen; and he gives a correct account of the excretory ducts of the prostate gland, the verumontanum, and the anteprostates. One of the circumstances which the history of this period of anatomical science shows tended considerably to its improvement, is the attention with which Compara¬ tive Anatomy was beginning to be cultivated. In ancient times, and at the revival of letters, the dissection of the lower animals was substituted for that of the human body; and the descriptions of the organs of the latter were too often derived from the former. The obloquy and con¬ tempt in which this abuse involved the study of animal anatomy made it be neglected, or pursued with indifference, for more than two centuries, during which anatomists con¬ fined their descriptions, at least very much, to the parts of the human body. At this period, however, the preju¬ dice against Comparative Anatomy began to subside; and animal dissection, though not substituted for that of the human body, was employed, as it ought always to have been, to illustrate obscurities, to determine doubts, and to explain difficulties, and, in short, to enlarge and rectify the knowledge of the structure of animal bodies generally. For this revolution in its favour, Comparative Anatomy was in a great measure indebted to the learned societies which were established about this time in the different countries of Europe. Among these the Royal Society of London, embodied by charter by Charles II. in 1660, and the Academy of Sciences of Paris, founded in 1665 by Colbert, are undoubtedly entitled to the first rank. Though later in establishment,tlie latter institution was distinguish¬ ed by making the first great efforts in favour of Compara¬ tive Anatomy; and Perrault, Pecquet, Duverney,and Mery, by the dissections of rare animals obtained from the royal menagerie, speedily supplied valuable materials for the anatomical naturalist. In England, Nehemiah Grew, hd- ward Tyson, and Samuel Collins, cultivated the same de¬ partment with diligence and success. The first has left an interesting account of the anatomical peculiarities o the intestinal canal in various animals ; and the second, in the dissection of a porpoise, an opossum, and an ourang outang, adduces some valuable illustrations of the com¬ parative differences between the structure of the human body and that of the lower animals. To the third be¬ longs the merit of conceiving, and executing on an en larged plan, a comprehensive system, embodying al t e information then extant. With the aid of Tyson an his own researches, which were both extensive and accu^ ^ ^ rate, he composed a system of anatomical knowledge, i which he not only delivers ample and accurate description of the structure of the human body, and the var.1rum\er and Peyer; and by demonstrating the communi- ution of the arteries and veins of the mesentery. , 1 he anatomical genius of Italy, which had slumbered since the death of Malpighi, was destined once more to ?'.lvc,n Lancisi, Valsalva, and his illustrious'pupils Santo- Morgagnj. Valsalva especially distinguished him- by his description of the structure of the ear, which, possessing still greater precision and minuteness than r la|,0. Duverney, is valuable in setting the example of oo enng anatomy altogether a science of description. Santorini, who was professor at Venice, was no unworthy friend of Valsalva and Morgagni. His anatomical observa¬ tions, which relate to the muscles of the face, the brain, and several of the nerves, the ducts of the lacrymal gland, the nose and its cavities, the larynx, the viscera of the chest and belly, and the organs of generation in the two sexes, furnish beautiful models of essays distinguished for per¬ spicuity, precision, and novelty, above any thing which had then appeared. These observations, indeed, which bear the impress of accurate observation and clear con¬ ception, may be safely compared with any anatomical writings which have appeared since. Those on the brain are particularly interesting. Morgagni, though chiefly known as a pathological anatomist, did not neglect the healthy structure. His Adversaria, which appeared be¬ tween 1706 and 1719, and his Epistles, published in 1728, contain a series of observations to rectify the mistakes of previous anatomists, and to determine the characters of the healthy structure of many parts of the human body. Many parts he describes anew, and indicates facts not previously observed. All his remarks show how well he knew what true anatomical description ought to be. In this respect, indeed, the three anatomists now mentioned may be said to have anticipated their contemporaries nearly a century; for, while other authors were satisfied with giv¬ ing loose and inaccurate or meagre notices of parts, with much fanciful supposition, Valsalva, Santorini, and Mor¬ gagni, laboured to determine with precision the anatomical characters of the parts which they describe. The same character is due to Winslow, a native of Den¬ mark, but, as pupil and successor of Duverney, as well as a convert to Catholicism, naturalized in France, and finally professor of anatomy at the Royal Garden. His exposi¬ tion of the structure of the human body is distinguished for being not only the first treatise of descriptive anatomy, divested of physiological details and hypothetical expla¬ nations foreign to the subject, but for being a close de¬ scription derived from actual objects, without reference to the writings of previous anatomists. About the same time Cheselden in London, the first Monro in Edinburgh, and Albinus in Leyden, contributed by their several trea¬ tises to render anatomy still more precise as a descriptive science. The Osteographia of the former was of much use in directing attention to the study of the skeleton, and the morbid changes to which it is liable. This work, however, magnificent as it was, was excelled by that of Albinus, who, in 1747, published engravings de¬ scriptive of the bones and muscles, which, perhaps, will never be surpassed either in accuracy of outline or beauty of execution. The several labours of this author, indeed, constitute an important era in the history of the science. He was the first who classified and exhibited the muscles in a proper arrangement, and applied to them a nomencla¬ ture which is still retained by the consent of the best anatomists. He gives a luminous account of the arteries and veins of the intestines, represents with singular fide¬ lity and beauty the bones of the foetus, inquires into the structure of the skin, and the cause of its colour in differ¬ ent races; represents the changes incident to the womb in different periods of pregnancy, and describes the rela¬ tions of the thoracic duct and the vena azygos with the contiguous parts. Besides these large and magnificent works, illustrated by the most beautiful engravings, six books of Academical Annotations were the fruits of his long and assiduous cultivation of anatomy. These con¬ tain valuable remarks on the sound structure and morbid deviations of numerous parts of the human body. To render the knowledge of the skeleton more com¬ plete, Duhamel and Delasone studied the minute structure 1700. 1717. 1719. 1728. 1740. 1732. 1713-22. 1720-32. 1720-40. 1733. 1736. 1737. 17M. 1734-04. 1739-43. 702 ANATOMY. 1751-52. 1753. History, of bone, and the process of ossification; William Hunter and Herissant investigated the texture of the cartilages; and Weitbrecht gave a copious and minute account of the ligaments. M. Lieutaud also, who had already la¬ boured to rectify many errors in anatomy, described with much accuracy the structure and relations of the heart and its cavities, and rendered the anatomy of the bladder very precise, by describing the triangular space and the mammillary eminence at its neck. Albinus found a worthy successor in his pupil Albert Von Haller, who, with a mind imbued with every depart¬ ment of literature and science, directed his chief atten¬ tion, nevertheless, to the cultivation of anatomical and physiological knowledge. Having undertaken at an early age (21) to illustrate, with commentaries, the physiological prelections of his preceptor Boerhaave, he devoted him¬ self assiduously to the perusal of every work which could tend to facilitate his purpose; and as he found numerous erroneous or imperfect statements, and many deficiencies to supply, he undertook an extensive course of dissection of human and animal bodies, to obtain the requisite infor¬ mation. For 17 years, during which he was professor at Goettingen, he dissected 400 bodies,1 and inspected their organs with the utmost care. The result of these assidu¬ ous labours appeared at intervals in the form of disserta¬ tions by himself, or under the name of some one of his pupils, finally published in a collected shape, between 174G and 1751 (Disputationes Anatomicce Selectiores) ; and in eight numbers of most accurate and beautiful en¬ gravings, representing the most important parts of the human body, e. g. the diaphragm, the uterus, ovaries and vagina, the arteries of the different regions and organs, with learned and critical explanatory observations. Some years after, when he had retired from his academical duties at Goettingen, he published, between 1757 and 1765, the large and elaborate work which, with singular modesty, he styled Elements of Physiology. This work, though professedly devoted to the latter science, rendered nevertheless the most essential services to the former. Haller, drawing an accurate line of distinction between the two, gave the most clear, precise, and complete de¬ scriptions of the situation, position, figure, component parts, and minute structure of the different organs and their appendages. The results of previous and coeval in¬ quiry, obtained by extensive reading, he sedulously veri¬ fied by personal observation ; and though he never rejected facts stated on credible authorities, he in all cases labour¬ ed to ascertain their real value by experiment. The ana¬ tomical descriptions are on this account not only the most valuable part of his work, but the most valuable that had then or for a long time after appeared; and it is perhaps a sufficient proof of their intrinsic merit, that they are still resorted to by the anatomist as the most faithful guide to many of his researches. It is painful, neverthe¬ less, to think, that the very form in which this work is com¬ posed, with copious and scrupulous reference to authori¬ ties, made it be regarded as a compilation only; and that the author was compelled to show, by a list of his person¬ al researches, that the most learned work ever given to the physiologist, was also the most abundant in original information.2 With the researches of Haller, it is proper to notice those of his contemporary, John Frederick Meckel, and his pupil John Godfrey Zinn. The former, who was professor of anatomy at Berlin, described with unrivalled 1748-51. accuracy the Gasserian ganglion, the first pair of nerves and its distribution, and that of the facial nerves general- yf ly, and discovered the spheno-palatine ganglion. HeW made some original and judicious observations on the tissue of the skin and the mucous net; and above all r he recognised the connection of the lymphatic vessels with the veins,—a doctrine which, though neglected, has been lately revived by Fohmann and Lippi. He also collected several valuable observations on the morbid states of the heart and brain. At the same time Zinn, who was professor of medicine at Goettingen, published on the eye a classical treatise, which demonstrated at once r the defects of previous inquiries, and how much it was possible to elucidate, by accurate research and precise de¬ scription, the structure of one of the most important or¬ gans of the human frame. As a general proof of the ex¬ traordinary merit of this work, it is sufficient to say, that in critical learning and descriptive accuracy it has not been equalled, and probably will never be surpassed. It was re-published after his death by Wrisberg. ] General anatomy, and the study of the atomic consti¬ tution of the tissues which had originally been com¬ menced by Leeuwenhoeck, Malpighi, and Ruysch, began at this period to attract more general attention. De Bergen had already demonstrated the general distribution of cellular membrane, and shown that it not only incloses every part of the animal frame, but forms the basis of every organ,—a doctrine which was adopted, and still more fully expanded, by his friend Haller, in opposition to 17| what was asserted by Albinus,3 who maintains that each part has a proper tissue. William Hunter at the same time gave a clear and ingenious statement of the difference between cellular membrane and adipose tissue, in which he maintained the general distribution of the former, and represented it as forming the serous membranes, and regulating their physiological and pathological properties,— doctrines which were afterwards confirmed by his brother John Hunter. A few years after, the department of ge¬ neral anatomy first assumed a substantial form, in the systematic view of the membranes and their mutual con¬ nections traced by Andrew Bonn of Amsterdam. In his inaugural dissertation De Continuationibus Membranarum, published at Leyden in 1763, this author, after some pre- 17 liminary observations on membranes in general and their structure, and an exposition of that of the skin, traces its transition into the mucous membranes and their several divisions. He then explains the distribution of the cellu¬ lar membrane and the aponeurotic expansions, and the periosteum and perichondrium, by either of which, he shows, every bone of the skeleton is invested and con¬ nected. He finally gives a very distinct view of the ar¬ rangement of the internal membranes of cavities, those named serous and fibro-serous, and the manner of their distribution over the contained organs. This essay, which is a happy example of generalization, is remarkable for the interesting general views of the structure of the ani¬ mal body which it exhibits; and to Bonn belongs the merit of sketching the first outlines of that system which it was reserved for the genius of Bichat to complete and embellish. Lastly, Bordeu, in an elaborate essay on the mucous tissue, or cellular organ, as he' terms it, brought forward some interesting views of the constitution, nature, and extent of the cellular membrane. Though anatomy was hitherto cultivated with much success as illustrating the natural history and morbid states of the human body, yet little had been done for the elucidation of local diseases, and the surgical means by lory, LK7 ’ 1-57. 17 1 “ Pene quadringentis mea manu dissectis hominum cadaveribus.” (Praefatio ad tom. vi. Elementorum Physiologix-) 2 z Annot. Acad. lib. iii. p. 2. ANATOMY. i 1'18- gist/. which they may be successfully treated. The idea of ap- plying anatomical knowledge directly to this purpose ap¬ pears to have originated with Bernardin Genga, a Roman surgeon, who published in 1672, at Rome, a work entitled Surgical Anatomy, or the Anatomical History of the Bones and Muscles of the Human Body, with the description of the Blood-vessels. This work, which reached a second edition in 1687, is highly creditable to the author, who appears to have studied intimately the mutual relations of different parts. It is not improbable that the example of Genga led Palfyn, a surgeon at Ghent, to undertake a similar task about 30 years after. For this, however, he was by no means well qualified ; and the work of Palfyn, though bearing the name of Surgical Anatomy, is a miserable compilation, meagre in details, inaccurate in description, and altogether unworthy of the honour of be¬ ing republished, as it afterwards was, by Antony Petit. While these two authors, however, were usefully em¬ ployed in showing what was wanted for the surgeon, others were occupied in the collection of new and more accurate facts. Albinus, indeed, ever assiduous, had, in his account of the operations of Rau, given some good sketches of the relative anatomy of the bladder and ure¬ thra; and Cheselden had already, in his mode of cutting into the urinary bladder, shown the necessity of exact knowledge of the relations of contiguous parts. The first decided application, however, of this species of anatomical research it was reserved for a Dutch anatomist of the 18th century to make. Peter Camper, professor of Anatomy at Amsterdam, published in 1760 and 1762 his anatomico- pathological demonstrations of the parts of the human arm and pelvis, of the diseases incident to them, and the mode of relieving them by operation. These observations are of the utmost value. The situation of the blood-ves¬ sels, nerves, and important muscles, is explained with the greatest clearness; and though the engravings are rather bold and accurate than elegant, they constitute a wrork indispensable to the anatomical reader. His remarks on the lateral operation of lithotomy, which contain all that was then known on the subject, are exceedingly inter¬ esting and valuable to the surgeon. It appears further that he was the first who examined anatomically the me¬ chanism of ruptures, his delineations of which were pub¬ lished in 1801 by Soemmering. It had been originally observed by Riolan, Severinus, Rudbeck, Harvey, and De Graaf, that in the foetus the testicles are situate in the abdomen; but this observa¬ tion, so pregnant with important results, appears to have been overlooked, nay doubted, till verified by Haller, who showed that their removal from this region is connected with the formation of congenital hernia. The situation of the testicles previous to birth, their gradual descent into the scrotum, and the mode in which a portion of intestine may slip down with them, was still more fully investigated by William Hunter, by Camper, and finally by John Hunter ; and the peculiarities of the inguinal canal, and the man¬ ner in which its persistence after birth, or its re-opening, may occasion hernial protrusions, have been well explain- ed by Sandifort, Scarpa, Sir Astley Cooper, Allan Burns, and Lawrence, and more recently by Hesselbach and Langenbeck. The attention of anatomists was now directed to the elucidation of the most obscure and least explored parts of the human frame—the lymphatic vessels and the nerves. Although, since the first discovery of the former by Asellius, Rudbeck, and Pecquet, much had been done, es¬ pecially by Ruysch, Nuck, Meckel, and Haller, many Points, notwithstanding, relating to their origin, and dis¬ tribution in particular organs, and in the several classes of animals, were imperfectly ascertained or entirely un¬ known. William Hunter investigated their arrangement, and proposed the doctrine that they are absorbents; and John Hunter, who undertook to demonstrate the truth of this hypothesis by experiment, discovered, in 1758, lym¬ phatics in birds in the neck. As this doctrine required the existence of this order of vessels, not only in quadru¬ peds and birds, but in reptiles and fishes, the inquiry at¬ tracted attention among the pupils of Hunter; and Wil¬ liam Hewson at length communicated, in December 1768, to the Royal Society of London, an account of the lac- teals and lymphatics in birds, fishes, and reptiles, as he had discovered and demonstrated them. The subject appears about the same time to have been investigated by the se¬ cond Monro, who indeed claimed the merit of discovering these vessels in the classes of animals now mentioned But whatever researches this anatomist may have insti¬ tuted, Llewson, by communicating his observations to the Royal Society, must be allowed to possess the strongest as well as the clearest claim to discovery. The same au¬ thor, in 1774, gave the first complete account of the ana¬ tomical peculiarities of the lymphatic system in man and other animals, and thereby supplied an important gap in this department. Hewson is the first who distinguishes the lymphatics into two orders, the superficial and the deep, both in the extremities and in the internal organs. He also studied the structure of the intestinal villi, in which he ve¬ rified the observations of Lieberkuhn ; and in inquiring into the minute structure of the glands, he adopted the views of Ruysch. He finally applied his anatomical discoveries to explain many of the physiological and pathological phe¬ nomena of the animal body. Ten years after, John Sheldon, another pupil of Hunter, gave a second history and descrip¬ tion of the lymphatics, which, though divested of the charm of novelty, contains many interesting anatomical facts. He also examined the structure of the villi. And, lastly, Cruikshank, in 1786, published a very valuable history of the anatomy of the lymphatic system, in which he main¬ tains the accuracy of the Hunterian doctrine, that the lymphatics are the only absorbents; gave a more minute account than heretofore of these vessels, of their coats and valves; and supplied the defect left by Hewson, by explaining the structure of the lymphatic glands. He also injected the villi, and examined them microscopically, verifying most of the observations of Lieberkuhn. The origin of the lymphatics he maintains rather by inference than direct demonstration. To these three works, though in other respects very excellent, it is a considerable ob¬ jection that the anatomical descriptions are much mixed with hypothetical speculation and reasonings on properties, and that the facts are by no means always distinguished from mere matters of opinion. At the same time Haase published an account of the lymphatics of the skin and intestines, and the plexiform nets of the pelvis. To complete this sketch of the history of the anato¬ my of the lymphatic system, it may be added that JVIas- cagni, who had been engaged from the year 1//7 to 1781 in the same train of investigation, first demonstrat¬ ed to his pupils several curious facts relating to the ana¬ tomy of the lymphatic system. When at blorence in 1 /82, he made several preparations, at the request of Petei Leopold, grand duke of Tuscany; and when the Royal Academy of Sciences at Paris announced the anatomy of this system for their prize essay appointed for March 1784, Mascagni resolved on communicating to the public the results of his researches—the first part of his com¬ mentary, with four engravings. Anxiety, howevei, to complete his preparations detained him at Florence till the close of 1785; and from these causes his work did 1746-48- 51. 1782* 704 ANATOMY. History, not appear till 1787. These delays, however, unfavourable -^^^as they were to his claims of priority to Sheldon and Cruikshank, were on the whole advantageous to the per¬ fection of his work, which is not only the most magnifi¬ cent, but also the most complete, that ever was published on the lymphatics. In his account of the vessels and their valves, he confirms some of Hewson’s observations, and rectifies others. Their origins he proves by inference much in the same manner as Cruikshank; but he antici¬ pates this author in the account of the glands, and he gives the most minute description of the superficial and deep lym¬ phatics, both in the members and in the internal organs. General accounts of the nerves had been given with various degrees of accuracy by Willis, Vieussens, Winslow, and the first Monro; and the subject had been much rec¬ tified and improved by the indefatigable Haller. The first example of minute descriptive neurography was given in 1748 by J. F. Meckel, whose account of the fifth pair, and their connection with the intercostal, and of the nerves of the face, will long remain a lasting proof of ac¬ curacy and research. The same subject was investigated in 1765 by Hirsch, and in 1777 by Wrisberg. In 1766 Metzger examined the origin, distribution, and termina¬ tion of the first pair,—a point which was afterwards very minutely treated by Scarpa in his anatomical disquisitions published in 1780; and the internal nerves of the nostrils were examined in 1791 by Haase. The optic nerve, which had been studied originally by Varoli, and after¬ wards by Mery, Duverney, Henkel, Moeller, Hein, and Kaldschmid, was examined with extreme accuracy, with the other nerves of the organ of vision, by Zinn, in his elaborate treatise. The phrenic nerves, and the oesopha¬ geal branches of the eighth pair, were studied by Haase; the phrenic, the abdominal, and the pharyngeal nerves, by Wrisberg; those of the heart most minutely by Andersch ; and the origins, formation, and distribution of the intercos¬ tal nerve, by Iwanoff, Ludwig, and Girardi. The labours of these anatomists, however, were eclipsed by the splendid 1783. works of Walter on the nerves of the chest and belly; and !794. those of Scarpa on the distribution of the 8th pair, and splanchnic nerves in general. In minuteness of descrip¬ tion, and in beauty of engraving, these works have not yet been equalled, and will never perhaps be surpassed. About the same time Scarpa, so distinguished in every branch of anatomical research, investigated the minute structure of the ganglions and plexuses. 1780. The brain was also studied with great attention by Ma- lacarne, Vicq d’Azyr, and Soemmering; more recently lleil examined the minute structure of the organ and its component parts with unrivalled research and accuracy; and Rolando studied the structure of the cerebellum. Lastly, the anatomy of the gravid uterus, which had been originally studied by Albinus, Roederer, and Smel- lie, was again illustrated most completely by William 1774. Hunter, whose engravings will remain a lasting memorial of scientific zeal and sculptorial talent. The perfection which anatomical science has attained, has been evinced during the last 30 years in the improved character of the systems published by anatomists. The first who gave a good modern system was Sabatier; but his work was speedily eclipsed by the superior merits of the treatises of Soemmering, Bichat, and Portal. To the first belongs the character of being at once the most learned and critical, and at the same time the most pre¬ cise, yet published. The General Anatomy of Bichat is a monument of his philosophical genius, which will last as long as the structure and functions of the human body are objects of interest. His Descriptive Anatomy is dis¬ tinguished by clear and natural arrangement, precise and accurate description, and the general ingenuity with which Hist the subject is treated. The physiological observations are in general correct, often novel, and always highly interesting. It is unfortunate, however, that the inge¬ nious author was cut off prematurely during the pre¬ paration of the third volume. It must nevertheless be acknowledged, that if the two last ones betray the want of the genius of Bichat, they are pervaded with the general spirit by which the others are impressed, and are highly creditable to the learning, the judgment, and the diligence of MM. Roux and Buisson. The system of Portal is a valuable and correct digest of anatomical and pathological knowledge, which, in exact literary informa¬ tion, is worthy of the author of the History of Anatomy and Surgery, and, in accuracy of descriptive details, shows that M. Portal trusts not to the labours of his predecessors only. Since the appearance of these stand¬ ard works, Meckel published a Manual, which combines the philosophical generalizations of Bichat with the pre¬ cise description and pathological knowledge of Portal. This work has been recently translated into French. Lastly, Cloquet formed, on the model of the Descriptive Anatomy of Bichat, a system in which he avails himself of the literature and precision of Soemmering, and the details of Portal. The system of Gordon is imperfect, its completion being interrupted by the death of the author; but, so far as it goes, it gives a correct summary of Gene¬ ral Anatomy, and some accurate descriptive details of the heart and brain. The work of Dr Monro is entitled to mention in this place, as an elementary treatise, containing, with anatomical description, a good deal of physiological and pathological matter. These, however, must be con¬ sidered foreign to the subject. Of treatises on particular departments, those of Blu- menbach on the bones, Innes and Sandifort on the mus¬ cles, the several anatomical writings and engravings of Charles Bell on the arteries, the nerves, and the brain, Barclay on the arteries, Tiedemann on the nerves of the uterus, and the same author’s engraved delineations of the arteries, and Harrison’s excellent work on the arte¬ ries, deserve notice. The minute structure of bone which had been examined by Scarpa, was again studied by that indefatigable inquirer, and in this country by How- ship. The structure of the lungs was investigated by Reisseissen, by Magendie, and Sir E. Home. On the anatomy of the nervous system numerous treatises have lately appeared. Joseph and Charles Wenzel investigat- 1812 ed the minute structure of the brain in man and the lower animals; Tiedemann traced the development of the organ in the foetus, and rectified many errors on its formation and minute structure; Sir Everard Home and M. Bauer investigated its atomic constitution by the mi¬ croscope ; Lobstein investigated the structure and dis¬ tribution of the great sympathetic nerve ; Bellangeri pub¬ lished an accurate description of the spinal chord and its nerves ; and, lastly, Charles Bell, in his great work on the nervous system, developes and establishes the truth of the ancient theory of the separate nature of the nerves of motion and those of sensation. Comparative Anatomy has been diligently cultivated by Daubenton, Pallas, Haller, John Hunter, and the second Monro, and more recently by Cuvier, Dumeril, Home, Tiedemann, and Meckel. In the foregoing account we have been anxious to trace merely a general sketch of the progressive advancement of anatomical discovery, from the first cultivation of the art to the present time. To mention every circumstance is impracticable, and would have extended this outline much beyond its legitimate limits. Though no name of genuine r- k. ANATOMY. Hum importance, however, has been omitted, every one not Anally, directly connected with strict anatomy has been excluded. At the same time it has been found impossible to specify every individual who has contributed at different periods to the improvement of the science ; and these we shall in general notice occasionally as we require to speak of them in the account of particular parts. For more minute and detailed information, we refer in general to the elaborate 705 History of Anatomy and Surgery by Portal, the Biblio- Human theca Anaiomica of Haller, and the critical and learn- Anatomy ed history of Lauth. It is unfortunate that the latter work is not completed. But by combining its perusal with that of the works already mentioned, and several of the chapters of Sprengel’s History of Medicine, the anato¬ mical inquirer will form very just ideas of the literary his¬ tory of his science.1 HUMAN ANATOMY.

Human vessels for exposing the latter blood to the influence of Anatomy, the atmosphere. They have further a mouth with two horizontal jaws ; distinct oi’gans of vision, hearing, smell, and taste, lodged in the cavities of the face; never more than four members; separate sexual organs; and con¬ siderable similarity in the arrangement of the central masses and the ramified chords of the nervous system. In all the vertebrated animals the blood which serves for the secretion of bile is the venous, which has circulated in the intestines, and which is afterwards made to un¬ dergo a ramifying distribution in the portal vein. In all the vertebrated animals also a peculiar secretion is form¬ ed from the arterial blood by two large glands, denomi¬ nated kidneys. In the second general division, which are destitute of those firm pieces named bones, the central portion of the nervous sj'stem, instead of being inclosed in portions of the skeleton, is placed on the oesophagus, and, with the other internal organs, is inclosed in a general soft en¬ velope, contractile, corresponding to the skin, to which the muscles are attached, and in which stony patches named shells are occasionally formed. Of the four proper organs of sensation, those only of taste and sight are observed; and the last are often wanting. One family only are provid¬ ed with organs of hearing. There is always a complete system of circulation, and organs for respiration. Those of digestion and secretion are almost as complicated as in the vertebrated animals. The division of the animal world thus distinguished have been named Molluscous Ani¬ mals ; (Animalia Mollusca). In the third general division, the nervous system con¬ sists of two chords extending longitudinally along the belly, and swelling at intervals into knots or ganglions. The first of these, placed on the cesophagus, and distin¬ guished as the brain, is scarcely larger than the others. The covering of the trunk is divided by transverse folds into a number of rings, the integuments of which may be hard or soft, but to the interior of which muscles are in all cases attached. The sides of the trunk, though often provided with, are nevertheless often without, articulated members. The annular appearance of the trunk has given these animals the character of Articulated; (Animalia Articulata). They have been occasionally named Annulosa. This class of animal bodies is remarkable for present¬ ing the first transition from circulation in close tubes or vessels, to nutrition by imbibition, and the corresponding transition from respiration in circumscribed organs to that which takes place in air-tubes distributed through the whole body. The only distinct organs of sensation are those of taste and sight.; and a single family have or¬ gans of hearing. The jaws, when present, are lateral. In these three divisions of animals the organs of motion and sensation are arranged symmetrically on both sides of an axis or imaginary line. In a fourth class they are dis¬ tributed circularly round a centre. In these, which in homogeneous structure approach the nature of plants, neither distinct nervous system nor proper organs of sen¬ sation are observed. Scarcely do we recognise traces of circulation. The organs for respiration are almost always at the surface of the body. Most of them have for intes¬ tine a sac without vent; and some present only a homo¬ geneous pulp, movable and sensible. To this class, which comprehends those beings denominated since the time of Aristotle zoophytes fur a), or animal plants, the name of Radiated Animals has been recently applied ; (Animalia Radiata). The vertebrated animals, however similar in general characters, present certain peculiarities by which they are naturally distinguished into classes. The first, and per- u haps the most striking difference, is in the mode of birth, Anat v one large division being separated from the body of the^v 7 female parent in a state of complete life, and therefore denominated viviparous; the other being detached in the form of an ovum or egg, which, though possessed of the elements of life, is not yet endowed with it, and requires for the full developement of that principle the assiduous care of the parent. This difference, however obvious, is more apparent than real. In viviparous birth the foetus or new animal remains attached to the inner surface of the womb by means of nutrient blood-vessels, and is enveloped in membranes, which correspond very accurately to the coverings of the ova of oviparous ani¬ mals. The rupture of these membranes at the moment of birth or detachment from the body of the parent is the only circumstance which constitutes a material difference between viviparous and oviparous generation. The vivi¬ parous animals, nevertheless, are further distinguished by nursing their offspring by means of teats or mammce, glands destined for separating from the mass of blood the oleo- albuminous fluid denominated milk. A still more important source of distinction among the vertebrated animals is found in the disposition of the vas¬ cular organs destined for respiration. The blood, which proceeds from the heart by the distributing tubes or ar¬ teries to the different organs, thereby undergoes a certain change, in consequence of which it is no longer capable of answering the several purposes of nutrition, secretion, &c. which are necessary to the maintenance of the animal body in the healthy state. To fit it once more for these purposes, the blood, in whole or in part, is, by means of the veins, brought back to the heart, and thence conveyed by means of a system of arborescent tubes to the surface of an organ, where it is, through the interposition of a thin membrane, exposed more or less freely to the atmo¬ spheric air. When it is exposed directly to this fluid in¬ troduced into the body by means of a single tube divided into ramifying branches, the respiratory organ is denomi¬ nated lungs. When the blood, on the other hand, is ex¬ posed to atmospheric air by means of water, which passes over a pectiniform organ, the latter is denominated gills. Respiration varies, therefore, according as the structure of the organ allows the whole or part of the blood to be exposed to air, and according as this exposure is direct or indirect. Taken together, these circumstances may be viewed as the integrant or constituent elements of the quantity, ex¬ tent, or degree of respiration, which conversely, indeed, depends on two circumstances,—the quantity of blood present in the respiratory organ at any given moment, and the relative quantity of oxygen in the respired fluid. The organs of circulation may be double, so that the whole mass of blood which is brought by the veins from the remote parts must circulate in the respiratory organ before it is again distributed by the arteries;—or they may be single, so that one portion only of the regredient blood is made to pass through the respiratory organ, while the residue is distributed by the arteries without undergoing this circulation. Of this mode of respiration an example is given by the class of animals denominated Reptiles; (Reptilia ; Animalia Repentia) ; in which the heart is so constructed that only part of the blood is conveyed to the lungs, and in which, consequently, the amount or degree of respiration, and the concomitant qualities, vary according to the proportion of this fluid which goes to the lungs at each pulsation. In Fishes, on the other hand, though the circulation is two-fold, that is, distributory by means of arteries, and ANATOMY. Hum regredient by means of veins, the respiratory organ is Anattiy- formed for respiration through the medium of Water, and v/v^the blood thus exposed to air receives the influence of that only which is mingled or held in solution by the water. Their extent of respiration is therefore supposed to be less than that of reptiles, by reason of the imperfect exposure to the operation of the air. Their respiration may be termed hydro-aerial. In mammiferous animals, again, though the circulation is two-fold, or distributory and regredient, the respiration is single, or confined to the lungs only. Their extent of respiration is therefore superior to that of the reptiles, by reason of the shape of their circulatory organs, and to that of fishes by reason of the nature of the element in which they live. Their respiration is aerial. In another class of vertebrated animals, however, respi¬ ration assumes a form still more perfect and extensive, since not only is the circulation two-fold, and the respira¬ tion aerial, as in the mammalia, but their structure is such that the air of the trachea communicates with other cavi¬ ties, especially those of the bones, and surrounds the branches of the aorta as completely as it does those of the pulmonary artery. The effect of this arrangement with regard to the ambient atmosphere is at once to render these animals specifically lighter, and enable them to sup¬ port themselves in the air, and to restore and change the regredient or venous blood so completely, that when again distributed it may impart to the various organs the high¬ est degree of energy of which they are susceptible. From these characters a division of vertebrated animals may be formed in the following manner. ls£, Quadrupeds, in which the extent of respiration is moderate, and which are distinguished for walking or running, or other muscu¬ lar exertion with strength; 2c?, Birds, in which the extent of respiration is the greatest possible, and is connected with the levity of substance and energy of muscle requi¬ site for flight; 3c?, Reptiles, in which the small extent of respiration is connected with languor of motion and occa¬ sional seasons of torpor ; and, 4?A, Fishes, in which the still more limited form of the respiratory organ requires a fluid of nearly equal specific weight to their own bodies to enable them to move with facility. These characters are necessarily general; but they are so essential, that between them and the other circumstances of organization proper to each class, and especially those relating to motion and sensation, a necessary relation exists. To the quadrupeds, mammiferous animals, or viviparous vertebrated animals, which form the first of these great classes, this place belongs, not only by the mode of gene¬ ration and respiration, but by the more perfect form of the animal functions, and the higher degree of intelligence which their habits and actions indicate. They are less under the influence of that blind animal propensity deno¬ minated instinct, which, like the properties of inorganic matter, seems to operate regularly and uniformly, inde¬ pendent either of sensation or volition. This class of animals is distinguished by great unifor¬ mity and regularity of structure and organization. In all of them the upper jaw forms part of the cranium; and upon this the lower jaw, consisting of two pieces only, articulat¬ ed by a prominent condyle to the temporal bone, is made to move. The neck consists of seven, and, in one species only, of nine vertebrae; to the sternum are attached cer¬ tain of the ribs, therefore named sterno-vertebral; the thoracic extremity is supported by a flat bone named shoulderblade {scapula, (ti;jjOmply suspended in the muscles, and in some species supported on the sternum by an intermediate bone, named collar-bone or clavicle (clavicula, xatj/j) ; in all excepting 707 the cetacea or whale-like animals, the first part of the Human pelvic extremity is fixed to the vertebral column, and forms Anatomy, a cincture or basin (pelvis), which in early life is divid-^^^^ ed into three pairs of bones, the os ilium, which is attach¬ ed to the spine, the os pubis, which constitutes the anterior or abdominal part of the pelvis, and the os ischium, which constitutes the most remote lateral portions of the pelvis. At the point of junction of these three bones on each side is a spherical cavity, in which the articular head of the thigh-bone is lodged. The scull, articulated by two prominent convex surfaces with the first vertebra, denominated atlas, may be repre¬ sented as consisting of three annular portions, an anterior formed by the frontal and ethmoid bones, a middle by the parietal and sphenoid bones, and a posterior by the occipital bone; the temporal bones, which are common to the face and scull, being interposed between the sphenoid, the oc¬ cipital, and the parietal bones. The face is formed essentially by the superior and in¬ ferior maxillary bones. Between the former is the cavity of the nostrils above, separated by the azygos bone named vomer ; before are the intermaxillary bones, and behind are the two palate bones. The entrance of the nasal cavity is bounded above by the proper nasal bones; and to a groove in this cavity are attached the inferior turbinated bones, so as to cover partially the entrance into the maxillary sinus. The brain consists of two similar hemispherical halves, united by a white mass, fibrous, especially in the transverse direction, named mesolobe, middle-band, or smooth body (ffaj/za nK'koiiOzg, corpus callosum). Each hemisphere con¬ tains an interior cavity, formed into definite-shaped masses, uniform and symmetrical. These cavities communicate with each other, and with a third situate on the mesial plane, and extending by a narrow canal to a fourth situate between the cerebellum and medulla oblongata. The pro¬ per matter of the cerebral and cerebellic hemispheres is united on the mesial plane in a mass named annular protuberance or pons Varolii, the lower surface of which is marked by transverse fibres, while the upper is mould¬ ed into four roundish eminences named nates and testes, or corpora quadrigemina. In the eye, lodged in a cavity of the cranium named orbit, and provided with two eye-lids and the vestige of a third, the crystalline lens is fixed by the ciliary processes; and the sclerotic, though firm, is cellular. The ear con¬ sists of a cavity named tympanum, closed externally by a membrane, and containing four minute but articulated and movable bones; an oval cavity or vestibule, in the orifice of which, one of these bones, the stapes, is fixed, and which communicates with three semi-circular canals; and, lastly, a spiral and tapering cavity, termed cochlea, parted by a thin plate into two spiral canals, one of which communicates with the tympanum, the other with the vestibule. The tongue is fleshy, and is supported by a joara&ofo-shaped bone, attached to the cranium by liga¬ ments, and to the larynx by membranes. The lungs, in number two, consisting of numerous tubular canals, proceeding from the windpipe, and termi¬ nating in an infinity of minute intersecting canals, named cells or vesicles, are inclosed without attachment, in a cavity formed by the ribs on each side, the diaphragm abdominally, and on the mesial plane by a membranous partition named mediastinum, and lined all over by a thin transparent membrane ; (pleura). At the guttural extre¬ mity of the windpipe is placed a particular apparatus, formed of cartilages put in motion by muscles, and which serves at once to regulate the quantity of air admitted into the tube, and to form the voice. This is named the 708 ANATOMY. Human larynx. A membranous fleshy production, suspended from Anatomy, the palate bones like a veil or valve, also moved at the will of the animal, establishes a direct communication between the larynx and the posterior nostrils. The intestinal canal is suspended to a duplicature of the peritoneum, named mesentery, between the folds of which the blood-vessels, nerves, lymphatics, and lymphatic glands pertaining to the canal, are lodged. The peritoneum, after passing over the intestines, forms a similar duplica¬ ture, which in the manner of a prolongation hangs freely before them. The urine, after secretion by the kidneys, is retained for a time shorter or longer in a distensible musculo-membra- nous bladder, and is expelled at various periods by a canal which opens, with few exceptions, in common with that of the organs of generation. The latter function is, in all the mammiferous animals, essentially viviparous. The ovum, consisting of the foetus and the enveloping membranes, immediately after con¬ ception is conveyed by appropriate tubes into the womb, to the inner surface of which it is attached by one or more plexiform clusters of vessels named placenta, and which furnish the blood requisite to the nourishment of the new body. In the earliest periods of uterine life, however, the mammiferous animals present a bladder or vesicula (vitellar membrane), analogous to that which con¬ tains the yolk of the oviparous animals, and receiving also mesenteric vessels. The peculiar mode in which viviparous animals nurse their offspring has been already noticed as that which distinguishes them particularly from the other three divisions of vertebrated animals. Another character peculiar to this class, are the hairs with which their integuments are provided, and which, though analogous to the feathers or quills of birds, are never¬ theless so characteristic, that they cannot be properly omit¬ ted in this enumeration. They are found in all mammi¬ ferous animals except the cetacea, in which marine re¬ sidence is supposed to render them less necessary. Last¬ ly, the blood of the mammalia is said to differ from that of oviparous animals in the shape of the coloured particles. In the former they are represented as lenticular, or of the shape of flat or oblate spheroids ; in the latter they are ovoidal, or like oblong spheroids. The mammiferous animals may be subdivided into subordinate groups or orders, according to certain natural characters in organization, which imply again peculiarities of habit and mode of life. These characters are derived from the organs of touch or prehension, on which de¬ pends their degree of ability or address ; and from the organs of mastication, which always bear a certain rela¬ tion to the nature of the food on which the individual animal subsists. The delicacy of the organ of touch depends on the number and mobility of the toes, and on the extent to which their tips are enveloped in nail or hoof. The lat¬ ter, enveloping entirely the part of the foot which touches the ground, impairs sensation, and renders the foot or paw incapable of prehension. When, on the contrary, a single plate of nail covers one of the surfaces of the tip of the toe, it not only leaves the other all its natural nicety of touch, but gives each toe that free and unembarrassed motion which enables the animal to seize and hold by the claws. The nature of the aliment used by animals bears a re¬ lation to . the teeth, with the form of which, again, the articulation of the jaws corresponds. To divide flesh, in¬ cisive teeth, like a saw, and jaws mutually opposed, like the blades of scissors, which simply open and shut, are requisite. In order to break grains or roots, teeth with a Hu n flat crown, and jaws admitting of horizontal motion, are re- Analiy, quired. The crowns of these teeth must further be un ~ equal or tuberculated, like the surface of a mill-stone, and their substance must be unequally firm, since certain parts are more exposed to attrition than others. All hoofed animals are necessarily herbivorous, or have flat-crowned teeth, since their feet do not allow them to seize living prey. Unguiculated animals, again, are susceptible of greater variety in the shape of the teeth, and their aliment depends on the mobility and de¬ licacy of their toes. One character of this description, which exercises great influence on their address, and mul¬ tiplies their means of industry, is the faculty of opposing the great toe to the others, or the thumb to the fingers,— a circumstance which essentially constitutes what is term¬ ed the hand, and which is carried to its highest perfection in the case of man, in whom the pectoral extremity is en¬ tirely free and susceptible of every mode of prehension. The several combinations now mentioned furnish cha¬ racters for distinguishing the mammalia into the follow¬ ing orders. Bim ana; hands on the thoracic extremity; supported vertically by the pelvic ex¬ tremities. Quad rumana; hands on the thoracic and pelvic extremities. Carnivora ; toes with¬ out free and opposable thumb. Rodentia ; no canine teeth; gnawing incisors. Edentata; no incisors; occasionally no canine; sometimes teeth want- -tilidl iyt Unguicu- lata; animals with separate toes or claws. ing. Marsupia- Unguuata; hoofed ani¬ mals. Cetacea ; animals with very short pel¬ vic extremi¬ ties, living in the water. Pachydermata ; dense, compact, cal¬ lous hide.

Herbivora. C. Capitulata. C. Capitones. Of these subdivisions, the first three orders are known by the common character of possessing all the three va¬ rieties of teeth, molar, canine, and incisive. They differ from each other in the possession of complete hands on the thoracic extremities, of imperfect hands on the four extremities, and in the want of thumb or opposable toe on the four extremities. The fourth order is peculiar in wanting canine teeth, and having incisors constructed for gnawing. In the fifth the toes are much constrained in motion, being sunk in large claws; and the incisors are wanting. Some genera want the canine teeth, and some are void of teeth entirely. This distribution of unguiculated animals would be complete, and would form a regular series, were it not in¬ terrupted by a small lateral series from New Holland, the native soil of the Marsupial animals. Of these, it is the peculiar distinction, that while some of their genera cor¬ respond to the Carnivora, others to the Rodentia, and a third set to the Edentata, in the form of teeth and na- ANATOMY. 709 Hilan ture of food, all of them agree m the common character of other words, by the length to which the two jaws are pro- Human Anartny. having a large sac or purse (marsupium) for retaining some longed.

These characters the Caspian and Black Seas, from which it has spread are neither arbitrary nor unessential. Both depend on by radiation. In confirmation of this, it may be observed invariable peculiarities of structure; and whatever at- that the tribes of the Caucasus, the Circassians, the tempts have been made by men, more distinguished for Georgians, and the Armenians, afford at the present hour ingenious paradox than accurate observation, to show that the most perfect and beautiful specimens of the human man was naturally quadruped, are readily refuted by ap- form. This race may be distinguished, by the analogy pealing to the anatomical configuration and disposition of of languages spoken by them, into three principal branches, the four members, and their relation to the trunk. 1.

Human 2. The Indian, German, and Pelasgic branch was Anatomy, much earlier divided into tribes, and mucli more exten- ^'x”'v^x‘'/sively diffused. The most numerous affinities may never¬ theless be traced between its four principal languages,— the Sanscrit, at present the sacred language of the Hin¬ doos, and the parent of all the dialects of Hindostan; the ancient language of the Pelasgi, the common parent of the Greek, the Latin, of many extinct languages, and of all the present dialects of southern Europe ; the Gothic or Tudesc, from which are derived the languages of the north and north-west, for instance the German, Dutch, Anglo-Saxon, and English, the Danish, Swedish, and their dialects; lastly, the Sclavonian, from which are sprung the languages of the north-east, the Russ, the Polish, the Bohemian, and the Vend. By this branch of the Caucasan race, philosophy, the sciences, and the arts, have been carried to the highest degree of perfection ; and of these they may be regarded as the chief depositaries. In Europe this race is believed to have been preceded by the Cdtce or Titano-Celtae, whose tribes, proceeding by the north, and formerly very exten¬ sive, were nevertheless confined to the most western points; and by the Cantabrians, who passed from Africa to Spain, and who are now almost lost among the nume¬ rous nations, the posterity of which is mingled in the European peninsula. The ancient Persians are derived from the same source as the Indians; and their descend¬ ants still bear the most conspicuous marks of connection with the European nations. 3. The Scythian and Tartar branch, bending first to the north and north-east, always erratic in the immense plains of these countries, have returned only to ravage the happier establishments of their brethren. From this branch issued the Scythians, who anciently distinguished themselves by inroads into Upper Asia; the Parthians, who destroyed the Greek and Roman dominions; the Turks, who subverted that of the Arabs, and subdued in Europe the last remnant of the Hellenic nation. The Fins and Hungarians are tribes of the same family disse¬ minated among the Sclavonian and Judaic nations. The north and east of the Caspian, their native soil, still main¬ tains tribes which have the same origin and speak similar languages; but they are intermingled with numerous other small septs of different origin and speech. The Tartar tribes remained more unchanged in that tract from which they long threatened Russia, which has at length subdued them, from the mouths of the Danube to beyond the Irtish. Their blood, nevertheless, has been mixed with that of the Mongols, many traces of which may be seen in the younger Tartars. On the east of this Tartar branch of the Caucasan race be¬ gins the Mongolian, which thence extends to the shores of the Eastern Ocean. Its branches, still nomadic, the Calmucks and the Kalkas, roam the Great Desert. Three times have their ancestors, under Attila, Gengis, and Timour, spread the terror of their name among the set¬ tled inhabitants of Europe and Asia. The Chinese consti¬ tute the branch most early civilized, not only of this race, but of known nations. The Mantchoux, a third branch, who recently conquered, still retain, China. To the same race in great part belong the Japanese and the Coreans, and almost all the hordes which stretch to the north of Siberia, under the sway of the Russians. Excepting some learned Chinese, the whole Mongolian race are attached to the sects addicted to the worship of Fo. The origin of this great race appears to be in the mountains of the Altaic range, as that of the Asio-Euro- pean is in the elevation of Caucasus. It is impossible, however, to trace the filiation of its branches with the same accuracy. The history of these nomadic nations is Hur as transitory as their establishments; and that of the Anat< Chinese, confined to the bosom of their empire, furnishes only short and unconnected views of the contiguous na¬ tions. The affinities of their modes of speech are further too little known to guide us in this labyrinth. The languages spoken in the north of the Ultra-Gan- getic peninsula, as well as that of Thibet, present some relations, at least in monosyllabic character, with the Chi¬ nese ; and the nations by whom they are spoken are not void of features of physical resemblance to the other Mon¬ golian tribes. The south of this peninsula, however, is inhabited by the Malays, a much handsomer race, whose breed and language have spread to the coasts of all the islands of the Indian Archipelago, and have occupied the greater number of those of the South Sea. In the largest of the former, especially in the wildest places, dwell other tribes, with crisp hair, black complexion, and negro fea¬ tures, all extremely barbarous. The best known are de¬ nominated Papous, which may be applied to the whole. Neither the Malays nor the Papous can be readily re¬ ferred to any one of the three great races. The former it is difficult to distinguish from the neighbouring races on each side the Caucasan Indians and the Mongolian Chinese. The Papous may be negroes anciently cast away in the Indian Seas ; but to determine this point we require both accurate figures and descriptions. The inhabitants of the north of the two continents, the Samoieds, the Laplanders, and the Esquimaux, spring, according to some, from the Mongolian breed ; according to others, they are degenerate slips of the Scythian and Tartar branch of the Caucasan breed. The Americans have not yet been clearly traced either to one or other of the races of the ancient continent; yet they are void of character sufficiently precise and constant to constitute a peculiar race : their copper-coloured skin is inadequate : by the dark hair and slender beard they ap¬ proach to the Mongols; but from these again they are distinguished by the well-marked features and the pro¬ minent nose. The modes of speech are as numerous as their tribes; and neither between themselves nor with those of the ancient world has any satisfactory analogy been traced. Of the various breeds now enumerated, the Caucasan or Asio-European is supposed to furnish the most per¬ fect model of the human frame ; and from this, therefore, anatomists derive their descriptions both of the body at large and of individual parts and organs. i '/■ The structure of the human body may be studied in two modes, either as an assemblage of organic substances endowed with characteristic physical and vital proper¬ ties, or as an assemblage of organs destined to effect par¬ ticular and definite purposes. The human body, like that of every other mammiferous animal, consists of several kinds of animal organic sub¬ stances endowed with appropriate characters and pro¬ perties. The substances thus distinguished have been named elementary textures, since into them, as into so many elements or integrant principles, the human body is supposed capable of being resolved. To enumerate these elementary textures, to ascertain their minute structure or organization, to investigate their distinctive properties, and to determine the extent to which they enter into the composition of particular organs, is the province of Gene¬ ral Anatomy. In this department the anatomist, ab¬ stracting from the shape, position, and mechanical configu¬ ration of parts, studies only their intimate and distinctive characters as organic substances. ANATOMY. G eral The human body may further be regarded as an Auamy. assemblage of organs, and sets of organs, destined to effect certain purposes. These purposes may be re¬ ferred to two general heads; those which are common to plants and animals, and those which are proper to the latter. The first comprehends nutrition and ge¬ neration, and have been named vital, organic, or auto¬ matic functions; the second embraces muscular action, sensation, and nervous influence or innervation, and are distinguished as animal functions. Since these purposes are effected by certain processes going on successively and simultaneously by the action of one or more organs, they are distinguished by the general name of functions, or or¬ ders of functions. Each function consists of several inte¬ grant and individual processes ; every process consists of one or more actions; each action depends on certain pro¬ perties; and properties in living bodies, though mechanical, chemical, or vital, are always connected either with the intimate structure of parts or with the configuration of organs. Thus nutrition is at once termed a function, and is said to consist of the several functions of di¬ gestion, absorption, circulation, respiration, and secre¬ tion. Generation, on the other hand, is said to be a func¬ tion consisting of several processes—the formation of germs or ova, the secretion of semen, impregnation, gesta¬ tion, and exclusion. Of the functions proper to animals, muscular action, modified in various modes, produces lo¬ comotion, gesture, voice, and several motions necessary to the performance of nutrition and generation. Sensa¬ tion may be said in all cases to depend on nervous action and the mechanism peculiar to each species of sensation. Nervous energy, again, may be said to consist of three pro¬ perties, those of receiving, transmitting, and recognising impressions. Lastly, a form of faculties connected with the immaterial or thinking part of the system peculiar to man constitutes what are named the intellectual functions. This division of the phenomena of living bodies into certain assemblages or functions, has given rise to a simi¬ lar division of these bodies into organs. An organ may be defined to be a part of a living body, of a definite shape, consisting of certain parts, composed of various elementary textures, the seat of one or more actions, and placed in a certain position and region. It rarely happens that one organ only is sufficient for the performance of a function. Several are commonly required to concur to the same general purpose; and hence the organs are ar¬ ranged in classes, sets, or assemblages, according to the functions to which they are subservient. Thus the or¬ gans subservient to the function of digestion consist of 711 tte nW-nxXf’rf as, °rgans of masNation; General t e pharynx and oesophagus as the tube of deglutition • Anatomy. t xe stomach as the organ of chymification; the duodenum and small intestines as that of chylification ; and the large as ^ temporary receptacle of the excremend- tial residue of food and drink. Such assemblages of or¬ gans have received, for want of better, the denomination of apparatuses; and the anatomist, when he designates a class of organs devoted to the performance of a specific function, is compelled to distinguish them as the appara¬ tus of digestion, the apparatus of absorption, of circula¬ tion, of respiration, of secretion, and so forth. To this method of distinction it may indeed be objected, that scarcely m one instance are all the organs of any appara¬ tus exclusively directed to the performance of the func¬ tion of that apparatus; and an organ concerned in the function of digestion may also contribute to that of circu¬ lation or respiration. Thus the larynx, though more par¬ ticularly the organ of voice, is also an organ of respira¬ tion ; the tongue and teeth, though belonging in one sense to the organs of digestion, are not less important as those of speech ; the diaphragm and abdominal muscles, though organs of respiration, are also accessary agents of diges- tion. These, however, are only to be regarded as examples of the ingenuity with which one organ in the animal body is made to answer several purposes ; and since all arrange¬ ments are ai tificial, or bear relation, not to the purpose of construction, but to the mind of the observer, the best course is to choose that which is least so, and which makes the nearest approach to the apparent objects of nature. To acquire a just knowledge of the organs of the hu¬ man body, with the views now stated, it is requisite to study their external shape and configuration, their posi¬ tion and contiguous relations, their ordinary size and di¬ mensions, the mechanical divisions of which they con¬ sist, their external characters and physical properties, their intimate structure and the elementary textures of which they are composed, their chemical constitution, their vital properties and consequent actions, and the uses to which they are obviously applied. The history of the organs, arranged upon these principles, constitutes the business of Descriptive, Particular, or Special Ana¬ tomy. The term Topographical Anatomy, which has al¬ so been proposed, is inadequate, since it indicates one class only of facts,—-those belonging to local relations. That of Morphology is equally objectionable. The term Organology, though preferable by reason of greater gene¬ rality, is not sufficiently appropriate to justify its adoption, to the exclusion of the one already in general use. GENERAL ANATOMY. Ihe human body consists of solid and fluid substances, the former of which are organized, and determine the shape of the body and its parts. These organized solids aie not in a strict physical sense solid and impenetrable, tost of them are soft, compressible, and elastic, by rea¬ son of the fluid matter contained in their interstices; and when deprived of this by desiccation, they shrink in va¬ rious degrees, and lose both bulk and weight. The ge¬ neral ratio of the fluid to the solid parts has been already stated to vary from 7 to 1, to 9 to 1. An adult carcass weighing perhaps from 9 to 10 stones, has been reduced by desiccation to 7^ lbs. In short, a human body may e reduced to nearly the weight of its skeleton, which 'aneB from 150 ounces =9| lbs. to 200 ounces =12^ lbs. Ihese organized solids agree in the possession of cer¬ tain general characters. Their internal structure ap¬ pears to consist of a union of solid and liquid matter, which is observed to exude in drops more or less abun¬ dant from the surface of sections. The solid parts are generally arranged in the form of collateral lines, some¬ times oblique, sometimes perfectly parallel, sometimes mutually intersecting. Such lines are denominated fibres, and occasionally filaments. In other instances the solids are observed to consist of minute globular or spheroidal particles, connected generally by delicate filaments. Most of these solids anatomists and miscroscopical observers have attempted to resolve into what they conceive to be an ultimate fibre or last element; but this inquiry leads beyond the bounds of strict observation. Most of the solids may be demonstrated to be pene- 712 ANATOMY. General trated by minute ramifying tubes or blood-vessels, which Anatomy, traverse their substance in every direction, and in which '*^S/^',b^is contained the greater part, perhaps the whole, of the fluid matter found in the solids. In a few in which rami¬ fying vessels cannot be positively demonstrated, their ex¬ istence is inferred by analogy from those in which they can. The filamentous, fibrous, or globular arrangement, with the distribution of arborescent vessels, constitutes organization. The substances so constructed are named organized tissues (telce, textus), or textures, or simply tis¬ sues. The organized solids also resemble each other in che¬ mical constitution. They may be resolved into proximate principles, either the same or very closely allied. The proximate principles most generally found are albumen, fibrin, and gelatine, one or other of which, sometimes more, form the basis of every tissue of the human body. Next to these are mucus, and oily or adipose matter. Osma- zome or extractive matter is found in certain tissues. And lastly, several saline substances, as phosphate of lime, carbonate of lime, soda, hydrochlorate of soda, are found in variable proportions in most of them. Of these prin¬ ciples albumen and fibrin, which are closely allied and pass into each other, are the most common and abundant. Osmazome, which is probably a modification of fibrin, is less frequent. These also are contained in the blood, and probably derived from that fluid. Gelatine, though not found in the blood, is nevertheless a principle of exten¬ sive distribution, being found in skin, cellular tissue, ten¬ don, cartilage, and bone. These proximate principles are resolved, in ultimate analysis, into carbon, oxygen, hydro¬ gen, azote, phosphorus, and sulphur. From the saline sub¬ stances, calcium, potassium, sodium, chlorine, iron, and manganese may be obtained. The organized solids which enter into the composition of the human body, though agreeing in the characters now mentioned, differ nevertheless in other respects. The most remarkable differences of this kind consist in pecu¬ liarities in the arrangement of their constituent fibres, peculiarities in the nature of these fibres, and different proportions or modifications of their proximate chemical principles. From one or other of these circumstances the organized solids may be referred to the following 17 elementary tissues:—Filamentous or cellular tissue, includ¬ ing ordinary cellular membrane and adipose membrane ; artery, vein, with their minute communications, termed capillary vessels, and the erectile vessels; lymphatic ves¬ sel, and gland; nerve, plexus, and ganglion; brain, or cerebral matter; muscle; white fibrous system, including ligament, periosteum, and fascia; yellow fibrous system, including the yellow ligaments, &c. bone and tooth; gristle or cartilage; fibro-cartilage; skin; mucous mem¬ brane ; serous membrane; synovial membrane; and last¬ ly, glandular structure, or the peculiar matter which forms the liver, the pancreas, the kidneys, the female breast, the testicle, and other organs termed glands. These tissues may be distinguished into orders, accord¬ ing to the mode of their distribution in the animal frame. -Several, for instance filamentous tissue, artery and vein, lymphatic vessel, and nerve, are most extensively distri¬ buted, and enter into the composition of all the other simple tissues. To these, therefore, which are named by Bichat general or generating systems, the character of textures of distribution may be applied. A second or¬ der, consisting of substances confined to particular regions and organs, and placed in determinate situations, viz. brain, muscle, white fibrous system, yellow fibrous system, bone, cartilage, fibro-cartilage, and gland, may be denomi¬ nated particular tissues. To a third order, consisting of substances which assume the form of a thin membrane, Ger expanded over many different tissues and organs, may be Ana< referred skin, mucous membrane, serous membrane, and^^ synovial membrane, under the denomination of enveloping tissues. It may indeed be objected, that the circumstance of mechanical disposition is insufficient to communicate a distinctive or appropriate character, and several of the tissues referred to the second head, e. g. fascia, must, on this principle, be referred to the third. The objection is not unreasonable. But it may be answered, that it is al¬ most vain to expect an arrangement entirely faultless; and the present is convenient in being on the whole more natural, and therefore more easily remembered, than any other. A distinct idea of it may be formed from the fol¬ lowing tabular view. Filamentous Tissue. Artery. I Vein. / Lymphatic Vessel. Nerve. General or Common Tissues. Capillary Vessel. ' Brain. Muscle.

The fluids of the animal body are various, but may be distinguished into three sorts; the circulating nutritious fluid named the blood, the fluids which are incessantly mixed with the blood for its renewal, and those which are separated from it by secretion. The blood is well known to be a viscid liquid, of red colour, peculiar odour, and saline, something nauseous taste. Its temperature in the living body is about 97°; its specific gravity is about 105 to water as 100. Its quantity is in the adult considerable, varying from 8 or 10 to 80 or 100 pounds. According to the results of microscopic observation it consists of red particles suspended in a serous fluid. On the shape of these red particles various opinions have been maintained. Generally represented as globular, Hewson describes them as flattened spheroids, or lenticu¬ lar bodies, a view which is partly confirmed by the obser¬ vations of Prevost and Dumas, and also of Beclard. The opinion of Home and Young, that the flattening of these globules is a process posterior to the discharge of the fluid, is not improbable. These particles have indeed since the time of Hewson been almost universally repre¬ sented as consisting of a central transparent whitish glo¬ bule, inclosed in a red translucent vesicle, which gives them the shape of an oblate spheroid. The diameter ot these particles is estimated, by the subdivided scale ot Kater, the micrometer of Wollaston, and the eriometerof Young, at YoW, and by the common micrometer, at xTTJtr of an inch. (Phil. Trans.) This description applies to the blood circulating in the vessels. Discharged from the vessels, it exhales, during the pro¬ cess of cooling, a thin watery vapour, consisting of water suspending animal matter capable of impressing the sense of smell, and undergoing decomposition. During the same ANATOMY. Ge;ra) space it is observed to be converted into a firm mass, Amtmy- which, though still soft and elastic, is entirely void of fluidity. As this process advances, a thin watery fluid, straw-coloured, not perfectly transparent, is observed to exude from every part of the solid mass, which also di¬ minishes in size, till at length it is found floating like a tolerably thick cake in the thin watery fluid. The thick solid mass is named the clot or coagulum; the watery fluid is denominated serum; and the process of the se¬ paration, which is spontaneous, is termed coagulation. The blood at the same time is said to discharge carbonic acid. The clot, if divided and washed in water often changed, or in alcohol or aqua potassce, may be deprived of its red colour, and made to assume a gray or bluish-white tint. This gray mass, which is tough, coherent, opaque, and more or less dense, homogeneous, but void of traces of organic structure, consists chiefly of albumen or fibrin, or a substance partaking of several of the characters of both. To this substance the blood owes its viscidity and its property of spontaneous coagulation; and from the circumstance of its resemblance to the lymph or albumi¬ nous fluid which is effused from wounds and inflamed surfaces, and to the fibrin of muscle, and the albumen of many of the tissues, it may be regarded as the most vital and nutritious part of that fluid. It is a mistake nevertheless to assert, as is done by Beclard and others, that this substance presents to the microscope the aspect and structure of muscular fibre. Its aspect is by no means so regular as this, nor can its particles be said to present traces of organic structure or arrangement. The red matter removed by washing is a mixture of serum, of globules, and of a peculiar colouring matter. Mo¬ dern chemistry shows that the latter is a particular sub¬ stance, insoluble in water, but susceptible of suspen¬ sion in it to an extreme extent, and consisting of animal matter combined with peroxide of iron. It is distinguish¬ ed by the name of zoohematine. Deprived of this, the globules are estimated by Bauer at of an inch in diameter. The serum, with the taste and odour of the blood, ra¬ ther alkaline, coagulates at 162° F. or on the addition of acids, nitrate of silver, or corrosive sublimate, and then resembles boiled white of egg. The coagulated matter is albumen; and a little water containing soda and salts of soda may be separated. It is a remarkable difference between this albumen, which is suspended in the serum, and that which constitutes the clot, that while the former requires heat as a re-agent, the latter assumes the solid form spontaneously. Blood also contains occasionally some oily matter, the presence of which renders the serum opaque and milky. The colour of the blood varies in different parts of the system. In the left auricle, ventricle, and arterial trunks generally, its colour is bright scarlet, a tint which it loses in the capillary vessels. In the veins, venous trunks, right auricle, right ventricle, and pulmonary artery, its colour is a dark or purple-red, or modena. As it moves from the trunk and branches through the minute divi¬ sions of the pulmonary artery, it gradually parts with this tint; and in the branches of the pulmonary veins it is found to have acquired the bright scarlet colour which it has in : .e left auricle, ventricle, and aorta. Hence the modena or dark-coloured blood is distinguished as venous, or proper to the veins; and the bright red or scarlet-co¬ loured as proper to the arteries. In the foetus, the blood contains little coagulable mat¬ ter ; and this principle is entirely wanting in the blood of the menstrual discharge. VOL. II. 713 The fluids received by the blood are chyle and lymph. General Chyle is derived from chyme, a gray pulpy substance, Anatomy, formed from the alimentary mass in the stomach and^-^^^ duodenum. Detached from this substance, and received by the chyliferous tubes, it is whitish and scarcely coa¬ gulable. In the mesenteric glands it becomes more coa¬ gulable, and assumes a rose colour. Lastly, in the thoracic duct, and before joining the mass of blood, it is distinctly rose-coloured, coagulable, and globular in ils particles. In the branches of the pulmonary artery it appears to become perfect blood. Lymph is a colourless, viscid, albuminous fluid, imperfectly known. Of the fluids separated from the blood, all cannot be said to belong to the animal body. Several, for in¬ stance the perspired fluid of the skin and lungs, the fluid of the cutaneous and mucous follicles, and the urine, become, after secretion, foreign to the body, and re¬ quire to be removed. Those belonging to the body are such as are prepared for some purpose within it, and after this are either re-absorbed, or, being decomposed, are ex¬ pelled. Of the former kind, fat, serum of serous mem¬ branes, and synovia, afford examples. To the latter de¬ scription belong tears, saliva, pancreatic fluid, bile, the seminal fluid of the male, and the milk of the female, all of which are the result of a distinct glandular secretion for a specific purpose, after which they are expelled from the economy. The urine, though also the result of glan¬ dular secretion, is nevertheless exempt from this rule, and though separated from arterial blood, is forthwith eliminat¬ ed. Its chief purpose seems to be to afford a convenient vehicle for ridding the system of superfluous azote, and to maintain the due proportion between this and the other ultimate principles, carbon, hydrogen, and oxygen. The fluids which fulfil a purpose in the economy are regarded as secretory, and are remarkable for a predomi¬ nance of alkali; those which do not are excrementitial, and are generally acid. BOOK I. CHAP. I.—THE COMMON TISSUES. Filamentous or Cellular Tissue. ( Tela Cellulosa,— Tissu Cettulaire,— Tissu Muqueux of Bordeu,— Corpus Cri- brosum Hippocratis,— Corps Cribleux of Fouquet,— Reticular Membrane of William Hunter.) The general distribution of the filamentous or cellular tissue was first maintained by Haller and Charles Augus¬ tus de Bergen, artd afterwards made the subject of elaborate discussion by William Hunter and Bordeu. It may be described as a substance consisting of very minute thready lines, which follow no uniform or invariable direc¬ tion, but which, when gently raised by the forceps, pre¬ sent the appearance of a confused and irregular net-work. As these minute lines cross each other, they form between them spaces of a figure not easily determined, and perhaps not uniform. By some authors these spaces or intervals have been named cells; but, accurately speaking, the term is not fortunately applied. The component lines, which do not exceed the size of the silk-worm threads, are so slender, that they do not form those distinct partitions which the term cell implies; and though by forcible dis¬ tension, such as takes place in insufflation, or separation by forceps, cavities appear to be formed, these, it will be found, are artificial, and result from the separation of an infinity of the slender filaments of which the part is com¬ posed. These interlinear spaces necessarily communicate on every side with each other; and indeed the most dis- 4 x ANATOMY. 714 General tinct way of forming a true idea of the structure of the Anatomy, cellular tissue, is to suppose a certain space of the animal body which is divided and intersected into an infinite mul¬ titude of minute spaces (areolce) by slender thready lines crossing each other. This description, derived from per¬ sonal observation, renders the name of filamentous more appropriate to this tissue than that of cellular, by which it is generally known. The interstitial spaces resulting from the interlacement of these filaments do not exist as distinct cavities in the healthy state, so that they cannot be said to contain any substance solid or fluid. But when an incision is made into this tissue in the living body, it is found, that if we except those fluids which issue from divided vessels, no¬ thing is observed to escape but a thin exhalation or va¬ pour, which is evidently of an aqueous nature. This is what some authors have termed, from its resemblance to the serous part of the blood, the cellular serosity (Bichat), and the quantity of which has been greatly exaggerated. In the living body it appears not to exist as a distinct fluid, but merely as a thin vapour, which communicates to the tissue the moist appearance which it possesses. This fluid is understood to be derived from the minute colourless capillaries named exhalants ; and it is supposed to be no sooner poured forth in an insensible manner, than it is removed by the absorbing power of lymphatics, minute veins, or both. It is further believed, that what¬ ever serous fluid is secreted into the interstitial spaces or cells of the filamentous tissue, is in the healthy state speedily removed; so that exhalation implies absorption ; and the filamentous tissue is therefore represented as the seat of incessant exhalation and absorption. The serous fluid of the filamentous tissue varies in quantity in different regions. In the cellular tissue of those parts which are free from fat, as in the eyelids, the prepuce, the nymphce and labia, and the scrotum, it is said to be more abundant than in others. The peculiar structure of those parts, which is cellular, may render any excess of serous fluid more conspicuous; for it is matter of observation, that in many persons otherwise healthy these parts are net unfrequently distended with serous fluid. On the other hand, it must be remarked that the submucous cellular tissue, and that which sur¬ rounds arteries, veins, and excreting ducts, which is de¬ licate in substance and compact in structure, contains but a small proportion of serous fluid, and does not readily admit its presence. This fluid has been generally said to be of an albumin¬ ous nature; and if it be identical with the serum of the blood, from which it is believed to be secreted, this cha¬ racter is not unjustly given it. Bichat, who maintained this opinion, injected alcohol into the filamentous tissue of an animal previously rendered emphj^sematous, and found in various parts whitish fiocculi, which he regarded as coagulated albumen. He also obtained the same result by immersing a portion of the scrotum in weak nitric acid; and when a considerable quantity of this tissue was boiled, it furnished much whitish foam, which Bichat regarded as albuminous.1 These experiments, however, are liable to this objection, that the effects in question may have arisen from coagulation of part of the filamentous tissue itself, which contains a considerable proportion of albuminous matter. The best mode of determining the point is to ob¬ tain the fluid apart, and to try the effects of the usual tests on it when isolated from the tissue in which it is lodged. The description here given applies to the proper fila¬ mentous tissue. This substance was shown by Ruysch, Gene and afterwards by William Hunter and Mascagni, to be Anatol •. penetrated by arteries and veins. Exhalants, absorbents,Vs>rv ^ and nerves, it is also said to receive. The arteries cer¬ tainly belong in the healthy state to the order of colour¬ less capillaries, which are nearly the same with exhalants. It does not appear that the nervous twigs observed to pass through this tissue are lost in it; for in general they have been traced to some contiguous part. Such are the general properties of this tissue, considered as an elementary organic substance extensively diffused through the body. In particular regions it undergoes some modifications, which may be referred to the follow¬ ing heads :—1. beneath the skin, or rather under the adi¬ pose membrane—the subcutaneous and intermuscular cel¬ lular tissue; 2. beneath the villous or mucous membranes —the submucous cellular tissue; 3. beneath the serous membranes—the subserous cellular tissue ; 4. round blood¬ vessels, excreting ducts, or rather organs—the inclosing tissue, vascular sheaths, &c.; 5. in the substance of or¬ gans—the penetrating cellular tissue. The situation of the subcutaneous filamentous tissue deserves particular notice. Though generally represent¬ ed as below the skin, it is not immediately under this membranous covering. The skin rests on the adipose membrane, beneath which again is placed the filamentous tissue, extending like a web over the muscles and blood¬ vessels, penetrating between the fibres and bundles of the former, surrounding the tendons and ligaments, and con¬ nected by these productions with a deep-seated layer, on which the muscles move, where they do not adhere to the periosteum and to bones. The extensive distribution of the subcutaneous filament¬ ous tissue, the mutual connection of its parts, and its ready communication with the filamentous tissue of the mucous and serous membranes, were demonstrated by Haller, William Hunter, and Bordeu, and have been clearly explained by Portal and Bichat. The principal points worthy of attention may be stated in the following manner. The filamentous tissues of the head and face communi¬ cate freely with each other, and with that of the brain by the cranial openings, and with the submucous tissue of the eyelids, nostrils, lips, and the inner surface of the mouth and cheeks. It communicates also with the sub¬ cutaneous tissue of the neck all round; and at the angle of the jaw, in the vicinity of the parotid gland, is the com¬ mon point of re-union. To this anatomical fact is referred the frequency of swellings and purulent collections in the region of the parotid in the course of various diseases of the head, face, and neck. The filamentous tissue of the neck may be viewed as the connecting medium between that of the head and trunk. From the former region it may be traced down¬ wards along the back, loins, breast, sides, flanks, and belly. At the cervical region, and between the shoulders, it is dense and abundant; and, surrounding the dorsal part of the vertebral column, it is connected with the me¬ diastinal tissue, the submucous tissue of the lungs, and the subserous tissue of the costal pleura. At the fore part of the neck it is in like manner connected with the abundant tissue of the pectoral region, and by means of that surrounding the larynx and trachea, ls£, with the submucous tissue of the bronchi; and, 2d, with the ante¬ rior mediastinum. Passing downwards, the same com¬ munication may be traced with the intermuscular tissue 1 Anatomic Gemrale, tom. i. p. 50. ANATOMY. Ge ral of the loins and belly, the tissue surrounding the lumbar Anamy- and sacral portion of the vertebral column, that connect- ^-■x^ing the mesentery and large vessels to the vertebrae, and extending all round under the muscular peritoneum, and into the pelvis, where, by means of the tissue at the pos¬ terior surface of the abdominal muscles, at the anterior surface of the iliacus interims, and through the obturator hole and ischiadic notch, it communicates with the fila¬ mentous tissue of the lower extremities. From the rec¬ tum and branches of the ischium it is continued along the perineum by the urethra, and into the scrotum. In the whole of this course, it is abundant in the space before the vertebrae, round the psoce and iliacus internus muscles, and round the bladder, rectum, prostate gland, and womb. The tissue surrounding the vertebral column communicates with that in the interior of the column by the intervertebral holes. The armpit may be considered as the point of union between the filamentous tissue of the trunk and that of the upper extremities, while the groin is the correspond¬ ing spot for the lower extremities. These facts should be kept in mind in observing the phenomena of diseases of this tissue. Notwithstanding this general connection, however, cer¬ tain parts of the tissue are so dense and close as to dimi¬ nish greatly the facility of communication. Thus, along the median line it is so firm, that air injected invariably stops, unless impelled by a force adequate to tear open its filaments; and water is rarely found effused in this situa¬ tion. In the neighbourhood of some parts of the skele¬ ton also, as at the crest of the ilium, over the great tro¬ chanter, and on the shin, the filamentous tissue is very dense and coherent. In chemical composition it consists principally of gela¬ tine, but contains some albuminous matter. Adipose Tissue. (Tela Adiposa,— Tissu Adipeux,— Tissu Graisseux.) The separate existence of an adipose membrane was suspected by Malpighi, maintained by De Bergen and Morgagni, and demonstrated by William Hunter. It was, however, confounded with the filamentous tissue, under the general name of cellular membrane, adipose mem¬ brane, and cellular fat, by Winslow, Portal, Bichat, and most of the continental anatomists, till distinguished and described by M. Beclard. According to the dissections of De Bergen and Mor¬ gagni, the demonstrations of Hunter, and the observa¬ tions of Beclard, its structure consists of rounded packets or parcels (pelotons) separated from each other by furrows of various depth, of a figure irregularly oval, or rather spheroidal, varying in diameter from a line to half an inch, according to the degree of corpulence and the part sub¬ mitted to examination. Each packet is composed of small spheroidal particles, which may be easily separated by dis¬ section, and which are said to consist of a cluster of vesicles stdl more minute, and agglomerated together by deli¬ cate cellular tissue. The appearance of these ultimate vesicles is minutely described by Wolff in the subcutane¬ ous fat, and by Monro and Clopton Havers in the mar¬ row of bones, in which the last two authors compared them to strings of minute pearls. If the fat with which tliese vesicles are distended should disappear, as happens m dropsy, the vesicles collapse, their cavity is obliterated, and they are confounded with the contiguous cellular tissue, without leaving any trace of their existence. Hunter, however, asserts, that in such circumstances the cellular tissue differs from the tissue of adipose vesi¬ cles, in containing no similar cavities ; and justly remarks 715 that the latter is much more fleshy and ligamentous than General the filamentous tissue, and contends, that though the adi- Anatomy, pose receptacles are empty and collapsed, they still exist. When the skin is dissected from the adipose membrane it is always possible to distinguish the latter from the fila¬ mentous tissue, even if it contain no fat, by the tough¬ ness of its fibres, and the coarseness of the web which they make. I he distinguishing characters between the cellular or filamentous and the adipose tissue may be stated in the fol¬ lowing manner:—D#, The vesicles of the adipose membrane are closed all round, and, unlike cellular tissue, they can¬ not be generally penetrated by fluids which are made to enter them. If the temperature of a portion of adipose membrane be raised by means of warm water to the li- quefying point of the contents, they will remain unmoved so long as the structure of the vesicles is not injured by the heat. If, again, an adipose peloton be exposed to a solar heat of + 40 centigr. though the fat be completely liquefied, not a drop escapes until the vesicles are di¬ vided or otherwise opened, when it appears in abundance. The adipose matter, therefore, though fluid or semifluid in the living body, does not, like dropsical infiltration, obey the impulse of gravity. 2c?, The adipose vesicles do not form, like cellular tissue, a continuous whole, but are simply in mutual contiguity. This arrangement is de¬ monstrated by actual inspection, but becomes more con¬ spicuous in the case of dropsical effusions, w'hen the fila¬ mentous tissue interposed between the adipose molecules is completely infiltrated, while the latter are entirely un¬ affected. 3c?, The anatomical situation of the adipose tissue is different from that of the filamentous tissue. The former is found, ls£, in a considerable layer imme¬ diately beneath the skin; 2c?, between the peritoneal folds which form the omentum and mesentery; 3rf, be¬ tween the serous and muscular tissues of the heart; and, 4?/«, round each kidney. In each of these situations it varies in quantity and in physical properties. In the least corpulent persons a portion of fat is deposited in the adipose membrane of the cheeks, orbits, palms of the hand, soles of the feet, pulp of the fingers and toes, flexures of the joints, round the kidney, beneath the cardiac serous membrane, and be¬ tween the layers of the mesentery and omentum. In the more corpulent, and chiefly in females, it is found not merely in these situations, but extended in a layer of some thickness almost uniformly over the whole person; and is very abundant in the neck, breasts, belly, mom ve¬ neris, and flexures of the joints. Besides the delicate cellular tissue by which the pack¬ ets and vesicles are united, the adipose tissue receives ar¬ terial and venous branches, the arrangement of which has been described by various authors, from Malpighi, who gave the first accurate account, to Mascagni, to whom we are indebted for the most recent. According to the latter, who delineates these vessels, the furrow or space between each packet contains an artery and vein, which, being sub¬ divided, penetrate between the minute grains or particles of which the packet is composed, and furnish each with a small artery and vein. The effect of this arrangement is, that each individual grain or adipose particle is sup¬ ported by its artery and vein as by a foot-stalk or pedun¬ cle, and that those of the same packet are kept together, not only by contact, but by the community of ramifica¬ tions from the same vessel. These grains are so closely attached, that Mascagni, who examined them with a good lens, compares them to a cluster of fish-spawn. Grutz- macher found much the same arrangement in the grains and vesicles of the marrow of bones. 716 ANATOMY. General It has been supposed that the adipose tissue receives Anatomy, nervous filaments; and Mascagni conceives-he has de¬ monstrated its lymphatics. Both points, however, are so problematical, that of neither of these tissues is the dis¬ tribution known. The substance contained in these vesicles is entirely inorganic. Always solid in the dead body, it has been re¬ presented as fluid during life by Winslow, Haller, Portal, Bichat, and most authors on anatomy. The last writer indeed states, that under the skin it is more consistent, and that in various living animals he never found it so fluid as is represented. The truth is, that in the human body, and in most mammiferous animals during life, the fat is neither fluid nor semifluid. It is simply soft, yielding, and compressible, with a slight degree of transparency or rather translucence. This is easily established by observ¬ ing it during incisions through the adipose membrane, either in the human body or in the lower animals. The properties and composition of fat form a subject for chemical rather than anatomical inquiry; and in this respect its nature has been particularly investigated by M. Chevreul. According to the researches of this che¬ mist, fat consists essentially of two proximate principles, stearine (ersug, sebum, sapo), and dame (iham, oleum). The former is a solid substance, colourless, tasteless, and al¬ most inodorous, soluble in alcohol, and preserving its soli¬ dity at a temperature of 138° centigrade. Elaine, on the contrary, though colourless, or at most of a yellow tint, and lighter than water, is fluid at a temperature of from 17° to 18° centigrade, and is greatly more soluble in al¬ cohol. Of this substance marrow appears to be merely a modification; and the membranous cavities or medul¬ lary membrane in which it is contained may be viewed as an intra-osseous adipose tissue. Little doubt can be entertained that animal fat is the result of a process of secretion ; but it is no easy matter to determine the mode in which this is effected. Malpighi, departing, however, from strict observation, imagined a set of ducts issuing from glands, in which he conceived the fat to be elaborated and prepared. To this he appears to have been led by his study of the lymphatic glands, and inability to comprehend how the process of secretion could be performed by arteries only. This doctrine, however, was overthrown by the strong arguments which Ruysch derived from his injections; and Malpighi himself after¬ wards acknowledged its weakness and renounced it. In short, neither the glands nor the ducts of the adipose membrane have ever been seen. Winslow, though willing to adopt the notion of Malpighi, admits, however, that the particular organ by which the fat is separated from the blood is unknown. Haller, on the contrary, aware of the permeability of the arteries, and their direct communication with the cells of the adipose tissue, and trusting to the testimony of Malpighi, Ruysch, Glisson, and Morgagni, that it existed in the ar¬ terial blood, saw no difficulty in the notion of secretion, or rather of a process of separation; and upon much the same grounds the opinion is adopted by Portal and others. Bichat, again, contends that no fat can be recognised in the arterial blood, and justly adduces the fact, that none can be distinguished in blood drawn from the temporal artery. 1 he accuracy of this fact is confirmed by subse¬ quent observation. This result is not at variance with the fact observed by Dr Traill, who found oily matter in ven¬ ous blood in two instances. In wounds in the human body during life, and in living animals, oily particles may be seen floating on the surface of the blood ; but these pro¬ ceed from division of the adipose vesicles. That fat does not exist in the arterial blood may be therefore admitted as an established point. The idea that Gem it is separated or strained from this fluid, therefore, must Anat! ? also be gratuitous ; and as such it is viewed by Bichat, who ^ considers the deposition of fat as the effect of exhalation, which is little more than a different name for the process termed by Haller secretion. Lastly, an opinion has been delivered by Mascagni, that while the arteries depositor pour forth an imperfect or crude oily fluid, the lymphatics absorb the thin parts, and leave the residue in a more solid and perfect form. In conclusion, all that can be affirmed regarding the formation of this substance is, that it is deposited by the blood-vessels, but by what particu¬ lar process, or in what form, is entirely unknown. The process by which the arteries of the adipose membrane secrete fat appears to be equally mysterious as that by which the vessels of muscle deposit fibrin, those of bone deposit osseous matter, and those of cartilage form that animal substance. Artery, Arterial Tissue. {Arteria,— Tissu Arteriel.) The structure of the arteries has been so much the sub¬ ject of examination at all periods of the history of ana¬ tomy, that to mention the authors by whom it has been described would be much the same as to enumerate all the anatomists who have ever written. To omit Galen, and some of those who wrote shortly after the revival of literature, descriptions of the structure of arteries have been given with different degrees of minuteness and accuracy by Willis, Yieussens, Verheyen, Lancisi, Bidloo, the first Monro, Morgagni, Ludwig, Haller, Delasone, Bichat, Gordon, Magendie, and by Mondini. Yet the descriptions given by these observers are discordant, and, with the exception of those given by the last four authors, do not accord with the characters which this substapce actually presents. The following account is derived principally from re¬ peated examination of the arteries of the human subject, occasionally compared with those of the more familiar domestic animals. Every arterial tube greater than one line in diameter is visibly composed of one adventitious and two essential substances: the first, the sheath, reputed to consist of condensed filamentous tissue; the two last, the proper ar¬ terial and internal tissues. ( Tunica propria et membrana intima.) 1. The inner surface of the arterial tube is formed by a very thin semitransparent polished membrane, which is said to extend not only in the one direction over the in¬ ner surface of the left ventricle, auricle, and pulmonary veins, but in the other to form the minute vascular termi¬ nations which are distributed through the substance of the different organs. This membrane is particularly de¬ scribed by Bichat under the name of common membrane of the system of red blood, because he believed it to exist wherever red blood was moving,—in the pulmonary veins, in the left side of the heart, and over the entire arterial system. The inner membrane may be demonstrated by cutting open or inverting any artery of moderate size, when it may be peeled off in the form of thin slips by the forceps. Or, if the tube be fitted on a glass rod, by removing the layers of the proper membrane in successive portions, the inner one at length comes into view in the form of a thin translucent pellicle, of uniform, homogeneous aspect, without fibres or other obvious traces of organization. I his membrane is supposed to be prolonged to form those minute vessels in which the proper coat cannot be traced. It is very brittle, and is distinguished during life by a re¬ markable activity in forming the morbid states to which ANATOMY. Geis’al arteries are liable. In other respects it is deemed by Anatny- Bichat peculiar, and, though similar to the proper mem- ^ '^brane, is to be considered as unlike any other tissue. Its chemical composition is not known. 2. Exterior to this common or inner membrane is placed a dense strong tissue of considerable thickness, of a dun yellowish colour, which is found to consist of fibres dis¬ posed in concentric circles placed contiguous to each other round the axis of the artery. If this substance be ex¬ amined either from without or in the opposite direction it will be found that, by proper use of forceps, its fibres can be separated to an indefinite degree of minuteness, even to that of a hair, and that they uniformly separate in the same direction. Longitudinal fibres are visible nei¬ ther in this nor in any other tissue of the arterial tube. This is the proper arterial tissue; {tunica propria.) Its uniform dun yellow colour is perceived through the semi¬ transparent inner membrane, and is most conspicuous either when this is removed, or when the outer cellular envelope is detached and the component threads separated from each other; and if it be less distinct in the smaller branches, it is because the tissue on which the colour de¬ pends is here considerably thinner. In this respect it va¬ ries in different regions. Though in general less dense and abundant as the arteries recede from the heart, it is thicker, ceeteris paribus, in those of the lower than in those of the upper extremities. In the vertebral and internal carotid arteries, and in those distributed in the substance of the liver, spleen, &c., it is thinner than in vessels of file same size in the muscular interstices. The nature of this tissue has been the subject of much controversy. It was long believed to be muscular, and to possess the properties of muscular fibre. Bichat showed that the arguments by which this opinion was supported are inconclusive, and that the arterial tissue has very few qualities in common with the muscular. The circum¬ stances from which he derived his proofs were its physi¬ cal and physiological properties. The arguments derived from the physical properties of this tissue are chiefly the following:—The arterial tissue is close, elastic, fragile, and easily divided by ligature; muscular fibre is more loose in structure, by no" means elastic; and, instead of being divided or cut by ligature as artery is, undergoes a sort of strangulation. The action of alcohol, diluted acids, and caloric, by means of hot fluids which are not corrosive, affords a proof of the che¬ mical difference of these animal substances. All of them produce in the arterial tunic a species of shrivelling or crispation, which seems to depend on more complete coa¬ gulation of one of the chemical principles; but no simi¬ lar effect takes place in muscular fibres. According to Berzelius, the proper arterial tunic contains no fibrin.1 Bedard, however, asserts that he has ascertained that it contains a portion of this principle; but nevertheless he¬ sitates to consider it as a muscular or fibrinous tissue, and cxpi esses his opinion that it would be with greater pro¬ priety referred to that order of substances which he has named yellow or tawny fibrous system. The consideration of the physiological or organic pro¬ perties leads to similar results. Neither mechanical nor chemical agents applied as stimulants produce any change or motion in the living arterial membrane. 1. The arte¬ ries of an amputated limb, exposed the moment after am¬ putation, while the muscles are in active motion, do not contract or move when punctured by the scalpel. 2. The 717 experiments of Bikker and Van-den-Bos with the electric General spark, and those of Vassalh-Eandi, Giulio, and Rossi with Anatomy, the galvanic pile, may be considered as disproved by the ‘ experiments of Nysten,2 who found no contraction in the human aorta after violent death, while the heart and other muscles could still be excited. In performing the same experiment with the artery of the living dog, this physio¬ logist was equally disappointed. 3. The circular contrac- j1.01? 01 the cahbre of an artery, either partially or wholly divided, depends not on irritability, but either on its elas¬ ticity, or on that property which it possesses of contract¬ ing stiongly the instant the distending agent is removed. I his power, which was rather happily named by Bichat contractihte par defaut dextension, is quite different from muscular contraction or irritability, and must not be con¬ founded with them; but it depends in a degree not much less on the living state of the body and the individual ar- tenal tube. 4. The contraction said to take place in liv¬ ing arteries after the application of alcohol, acids, or al- kalies, is to be ascribed to the chemical crispation^ and not to stimulant power. It does not relax. 5. These infe¬ rences are not inconsistent with the experiments of Thom¬ son, Philips, Hastings, and others, on minute arterial tubes, which may be admitted to possess something like irritability, or rather susceptibility of contraction, without the necessity of supposing the same property in the laro-e branches and trunks. 6. This is so much more probable, as in these minute arteries the proper arterial tunic is either wanting, or is so much thinner and so modified, that it is impossible to conceive its presence capable of affecting the result of experiments made to determine the degree or kind of arterial contraction. 3. The outer surface of the proper arterial tissue is en¬ veloped, as above noticed, in a layer of dense filamen¬ tous or cellular membrane, which is very firmly attached to it, and which was formerly considered as part of the arterial tissue. It is adventitious ; a modification of fila¬ mentous or cellular texture, which establishes a communi¬ cation between the artery and the contiguous parts, and is necessary to the nutrition and healthy state of the vessel. It incloses and transmits the minute vessels an¬ ciently denominated vasa vasorum {arteriolce arteriarum, Haller); and if detached even through a trifling extent, the arterial portion thus divided is sure to become dead, to be affected with inflammatory and sloughing action, and ultimately to give way and discharge the contents of the vessel. M. Beclard considers it a fibro-cellular mem¬ brane, which may in the larger arteries be divided into two layers; one exterior, similar to the general filament¬ ous tissue; the other inside, between the outer layer and the proper tissue, yellowish and firm, but still sufficiently distinct from the proper tunic. In the cerebral arteries it is wanting, and in most parts of the chest and belly its absence is supplied by a portion of pericardium, pleura, or peritoneum. Yet even there a thin layer of fine cellular tissue appears to connect these membranes to the proper tunic. In the extremities the cellular sheath is removed in dissecting arterial preparations. , At different periods several anatomists have maintained the existence of longitudinal fibres in arterial tissue; and even at the present day this notion is not entirely aban¬ doned. Morgagni was the first who, trusting to mere observation, the only sure guide in anatomical science, doubted the existence of these fibres, and was not ashamed to say he was unable to perceive them.3 Upon the same A View of the Progress of Animal Chemistry, by J.

General ground Haller would not admit their existence j1 and Bi- Anatomy. chat and Meckel positively deny them. I have repeated- examined almost every considerable artery of the hu¬ man body, and I have never been able to recognise any longitudinal fibres, either in the middle or proper coat, or in the thin internal membrane, as taught by Willis, Dou¬ glas, and Delasone. Though arterial tissue does not appear to be very vas¬ cular, it is furnished with arteries and veins (vasa vaso- rum, arteriolcc arteriarum), which do not come from the artery or vein itself, but from the neighbouring vessels.2 Thus the aorta at its origin is supplied with minute arte¬ ries from the right and left coronary, and in some instances with a proper vessel adjoining to the orifice of the right coronary artery, which Haller regards as a third coronary. The rest of the thoracic aorta derives its vessels from the upper bronchials, from twigs of the internal mammary ar¬ teries, from the bronchials, from the cesophageals, and from the phrenics. The abdominal portion is supplied from the spermatics, the lumbar, and in some instances the mesocolic artery. The same arrangement nearly is observed with regard to the veins. Few textures are more liberally supplied with nerves than arteries are. Almost every considerable trunk or vessel is surrounded by numerous plexiform filaments of nerves, many of which may be traced into the tissue of the artery. The anterior part of the arch of the aorta is abundantly supplied with branches from the superficial cardiac nerves, which Haller was unable to trace beyond the artery. The coeliac, the mesenteric, and the mesoco¬ lic arteries are invested with numerous plexiform nervous filaments derived from the large semilunar ganglion of the splanchnic nerve. The renal arteries in like manner are surrounded by numerous twigs of the renal plexus ; and each of the intercostal arteries at its origin receives nerv¬ ous threads from the intercostal nerves. This arrange¬ ment, which is observed chiefly in the blood-vessels going to the internal organs, led Bichat to announce it as a ge¬ neral fact, that the arteries derive their nerves almost exclusively from the ganglions and the gangliar nerves.3 The inference does not rest upon strict observation, and evidently owes its birth to the hypothetical opinions of this ingenious physiologist. All the arteries going to the extremities, the axillary, and iliac, and their branches, re¬ ceive nerves from the neighbouring nervous trunks, which are formed chiefly from cerebral or spinal nerves, and have no immediate connection with the system of the ganglions. In the internal carotid and the vertebral arteries, and their branches, nerves cannot be distinctly traced.4 Organized in the manner now described, it is requisite to take a short view of the anatomical connections of the arterial system, or to consider it in its origin, its course, and its termination. The arterial system of the animal body may be viewed as one large trunk divided into several branches, which again are subdivided and ramified to a degree of minute¬ ness which exceeds all calculation. It is requisite, there¬ fore, to consider the origin, Is#, of the aorta, the large trunk; 2dlyf of the branches which arise from it; and, Sdty, of the small vessels into which these are divided. Every one knows that the aorta is connected at its origin with the upper and anterior part of the left ventri¬ cle. The manner of this connection has been well exa- Go fai mined by Laneisi, by Ludwig, and particularly by Bichat. Ana ny.j It may be demonstrated by dissection, but is much more'^'^ '^ distinctly shown by boiling the heart with the blood-ves¬ sels attached. In a heart so treated, the thin internal membrane may be traced passing from the interior of the ventricle along the margin of its orifice to the inside of the arterial tube. Exactly at the point of union it is doubled into three semicircular folds, forming semilunar valves, and thence is continued along the whole course of the artery. This membrane is entirely distinct from the proper or fibrous coat. Of the latter, the cardiac extre¬ mity or beginning is notched into three semicircular sec¬ tions, each of which corresponds to the base or attached margin of a semilunar valve. These sections are attached to the aortic orifice of the ventricle by delicate filamen¬ tous tissue, but are not connected with the fleshy fibres of the heart; and at the angle or point of attachment the thin inner membrane is folded in so as to fill up a space or interval which is left between the margin of the orifice and the circumference of the proper arterial tissue, where it is notched or trisected. The aorta is soon divided into branches, which again are subdivided into small vessels. With the mathemati¬ cal physiologists it was a favourite problem to ascertain the number of branches into which any vessel might be subdivided. Keill made them from forty to fifty. Haller states that, counting the minutest ramifications, he has found scarcely twenty. The inquiry is vain, and cannot be subjected to accurate calculation. In no two subjects is the same artery found to be subdivided the same num¬ ber of times ; and in no two subjects are the same branches found to arise from the same trunk. A branch issuing from a trunk generally forms with it a particular angle. Most generally, perhaps, these angles are acute; but in particular situations they approach nearly to a right angle. Thus the innominata, left caro¬ tid, and left subclavian, issue from the arch of the aorta nearly at a right angle, at least to the tangent of the arch. The intercostals form a right angle with the thoracic aorta; the renal and lumbar arteries form a large acute angle, approaching to right, with the abdominal; and the cceliac comes off nearly in the same manner from the an¬ terior part of the vessel. The internal and external ca¬ rotids, again, the external and internal iliacs, the branches of the humeral, and those of the femoral, form angles more or less acute with each other. The angle which the spermatics make is, generally speaking, the most acute in the arterial system. I have already alluded to the structure of the arterial tissue at the divarications. These changes relate both to the inner and to the proper membrane. In the inside of the vessel the inner membrane is folded somewhat so as to form a prominent or elevated point, the disposition of which varies according to the angle of divarication. When this is rectangular, the prominence of the inner membrane is circular, and is equally distinct all round. 2d, WEen the angle is obtuse, as in the mesenteric artery, the prominence is distinct, and resembles a semicircular ridge between the continuation of the trunk and the branch given off, but indistinct on the opposite side where the angle is obtuse. 3c?, If the angle is acute, and that * “ Verum anatome et microscopium omnino fibras longitudinem sequentes nunquam demonstravit, aut mihi, aut aliis ante m scriptoribus, quorum auctoritate meam tueor.” (Elementa Physiologic?, lib. ii. sect. 1, § 7-) * Hunter, sect. iv. p. 131. 3 “ Le grand arbre a sang rouge ou I’artdriel est presque exclusivement embrasse par la premiere classe des nerves.” {Aiurto^ Generate, tom. i. p. 302.) 4 II. A. Wrisberg, Be JVervis Arterias Venasque comitantibus, apud Haller, Disput. Anatom. Select, tom. Hi. ANATOMY. Get.al formed by the branch with the continuation of the trunk Ana-ny- is obtuse, the beginning of the artery presents an oblique circle, the elevated half of which is near the heart, the other more remote. The arrangement of the fibres of the proper tissue is described by Ludwig from the divarication of the iliac arteries, and may be seen in any part of the arterial sys¬ tem where the vessels are large. The circular fibres se¬ parating form on each side a half-ring, from which is pro¬ duced a complete ring, which incloses the smaller rings formed by the circular fibres of the vessel given off. These circular fibres proceed to the prominence of the internal membrane already described, and are arranged round it much in the same manner in which those of the large vessel surround its inner membrane. In this, how¬ ever, no continuity between the rings of the large vessel and those of the small one can be recognised. The latter are inserted as it were into the former, and they are con¬ nected by the continuity of the inner membrane only. In observing the course or transit of arterial tubes, the principal point deserving notice is the sheltered situation which they generally occupy, their tortuous course, and their mutual communications. In the extremities they are always found towards the interior or least exposed part of the limb, generally deep between muscles, and sometimes lying along bones. When they are minutely subdivided, they enter into the interior of organs, without, however, sinking at once into their intimate substance. In the muscles they are lodged between the fibres; in the brain, in the convolutions; in glands, between their component lobes. In such situations they are generally observed to be more or less tortuous in the course which they follow. On the reasons of this much difference of opinion still prevails. (Bichat and Magendie.) In the course of the arteries, no circumstance is of greater moment than their mutual communications or inosculations (anastomoses). Of this there may be two forms, the first when two equal trunks unite, the second when a large vessel unites with a smaller one. Of the first, three varieties have been mentioned. Is#, Two equal trunks may unite at an acute angle to form one ves¬ sel. I bus, in the foetus, the ductus arteriosus and the aorta are conjoined; and the two vertebral arteries unite to form the basilar trunk. 2d, Two trunks may commu¬ nicate by a transverse branch, as the two anterior cere¬ bral arteries do in forming the anterior segment of the circle of Willis. So?, Two trunks may, by mutual union, form an arch, from the convexity of which the minute vessels arise, as is seen in the branches of the mesenteric arteries. (Plate XXIX. fig. 4.) The second mode of inosculation is frequent in the extremities, especially round the joints. The multiplied communications of the arterial system in these regions, though well known to anatomists, and enumerated by Haller, were first clearly and systematically explained by Scarpa, and afterwards by Cooper and Hodgson. The importance of this arrangement, in facilitating the motions «f the circulation,—in obviating the effects of local impe¬ diment in any vessel or set of vessels,—and in enabling the surgeon to tie an arterial trunk when wounded, affected with aneurism or any other disease,—has been clearly esta¬ blished by these authors. Their researches have shown, that there is not a single vessel which may not be tied with full confidence in the powers of the collateral circu¬ lation. Even the aorta has in four instances been found obstructed in the human subject, and a ligature has been put on its abdominal portion. (Cooper.) To ascertain the several modes in which arteries termi¬ nate has been a problem of much interest to the physio- 719 lopt, and of no small difficulty to the anatomist. The General alleged terminations, as believed to be established, are Anatomy, minutely and elaborately enumerated by Haller, who however, multiplied them too much according to the mo¬ dern acceptation of the term. 1. The first undoubted termination of arteries is imme¬ diately in veins. It is unnecessary to adduce in support of this fact the long list of observers enumerated by Hal¬ ler. It is sufficient to say that it was clearly established by the microscopical observations of Leeuwenhoeck, Cow- per, and Baker, by Haller himself, and by Spallanzani in his beautiful experiments on the circulation of the blood. 2. The second termination which may be mentioned here is that into the colourless artery, (arteria non rubra). This is sufficiently well established by the phenomena of injections. 3. A third termination which is supposed to exist, but of which no sensible proofs can be given, is that into colourless vessels supposed to open by minute orifices on various membranous surfaces, and therefore termed exha- lants. The nature of these vessels shall be considered afterwards. Haller admits a termination in, or communication with, lymphatic vessels, but allows that it is highly problemati¬ cal. Partial communications have been traced between arteries and lymphatics by several anatomists; but the point requires to be again submitted to accurate researches. Another mode of termination, that namely into excret¬ ing ducts, admitted by Haller, scarcely requires particular mention. So far as an artery can be said to terminate in such a manner, it would come under the head of that into exhalant vessels. Many of the proofs mentioned by Hal¬ ler, however, may be shown to be examples of a morbid state of the mucous membranes of these ducts, in which their capillary vessels are disorganized. In considering the several terminations of arteries, it is not unimportant to advert to the distribution of these vessels. Injections show that they penetrate into every texture and organ of the animal body, excepting one or two substances in which they have never yet been traced. But in different textures they are found in different de¬ grees ; and they may vary in extent even in the same texture in two different conditions. The parts which re¬ ceive the largest and most numerous vascular ramifications are the brain and spinal chord, the glandular organs, the muscles voluntary and involuntary, the mucous mem¬ branes, and the skin. In bones, on the contrary, in the fibrous membranes, and their modifications, tendons, and ligaments, and in the serous membranes, few arteries are seen to penetrate; and these are generally minute, some¬ times only colourless capillaries. In some textures arteries cannot be traced, though their properties indicate that they must receive vessels of some kind. Such are carti¬ lage and the arachnoid membrane. (Ruysch and Haller.) Lastly, arteries are not found in the scarf-skin, in nails, the enamel of the teeth, the hair, nor in the membranes of the umbilical chord. In early life bones are much more vascular than in adult age; and in the bones of young subjects arteries may be traced going out through the epiphyses into the cartilages, in which they cannot at a later period of life be demonstrated. (Phil. Trans. No. 470.) Vein, Venous Tissue.. (Ac4',— Vena,— Tissu Veneux.) The structure of the tubular canals, termed veins, has been much less examined by anatomists than that of the arteries. Some incidental observations in the writings of Willis, Glass, and Clifton Wintringham, comprise all that was published regarding them previous to the short ac- 720 ANATOMY. General count of Haller. Since that time they have been described Anatomy, with various degrees of minuteness and accuracy by John Hunter, Bichat, Magendie, Gordon, Marx,1 and Meckel. In the following account, the facts collected by these ob¬ servers have been compared with the appearance and visible organization presented by veins in different parts of the human body. The veins are membranous tubes extending between the right side or pulmonary division of the heart and the different organs in which their minute branches are rami¬ fied. Every venous tube greater than one line in diameter consists of three kinds of distinct substance. The outer¬ most is a modification of the filamentous tissue (rnembra- na cellulosd), and though less compact and less thick than the arterial filamentous envelope, is in every other respect quite similar, and is in general intimately connected with it. The innermost (membrana intima) is a smooth very thin membrane. Between these is found a tunic some- Avhat thicker, which is termed the proper venous tissue {tunica propria venae). The structure and aspect of this proper membrane shall be first considered. Is?, When the loose filamentous tissue in which the blood-vessels are inclosed, and the more delicate and firm layer immediately contiguous to the veins, are removed, the observer recognises a red or brown-coloured mem¬ brane, not thick or strong, but somewhat tough, which is the outer surface of the proper venous tunic. If dissected clean it is tolerably smooth; but however much so it can be made, a glass of moderate powers, or even a good eye, will perceive numerous filaments adhering to it, which appear to be the residue of the cellular envelope. According to Bichat, parallel longitudinal fibres, form¬ ing a very thin layer, may be distinguished in the larger veins; but he admits, although they are quite real, that they are always difficult to be seen at the first glance. In the trunk of the inferior great vein (vena cava inferior), they are always seen, he observes, more distinctly than in that of the superior; and they are always more obvious in the divisions of the former than in those of the latter vessel, and also in the superficial than in the deep-seated veins. These longitudinal fibres, he asserts, are more distinct in the saphena than in the crural vein, which ac¬ companies the artery. Lastly, he remarks, these fibres are proportionally more conspicuous in branches than in trunks. (Anatomic Generate, tom. i. p. 399.) Notwithstanding the apparent correctness of this de¬ scription, Magendie informs us he has sought in vain for the fibres of the proper venous membrane; and he re¬ marks that, though he has observed very numerous fila¬ ments interlacing in all directions, yet these assume the longitudinal and parallel appearance only when the tube . is folded longitudinally,—a disposition often seen in the larger veins. By Meckel, on the contrary, the accuracy of the obser¬ vation of Bichat is maintained. This anatomist states that he has, by the most minute dissections, assured him¬ self that these fibres are longitudinal; but he admits that they are not uniformly present in all parts of the venous system, and that in degree and abundance they are liable to great variation. He follows Bichat also in represent¬ ing these fibres as thicker and more distinct in the system of the inferior than in that of the superior cava, and in the superficial than in the deep veins. In the inferior cava of the human subject, certainly, filaments or fibres may be recognised. But instead of being longitudinal, they may be made to assume any di- Ge rection, according to the manner in which the filament¬ ous tissue is removed. For this reason probably these fibres are to be viewed as part of the filamentous sheath. In the saphena vein of the leg oblique fibres may be seen decussating each other; but it is doubtful whether these belong to the proper venous tissue or to the filamentous covering. The nature of this proper membrane, or venous fibre, as it is sometimes named (Bichat), is not at all known. Its great extensibility, its softness, its want of elasticity in the circular direction, or fragility, its colour and general aspect, distinguish it from the arterial tunic. It possesses some elasticity in the longitudinal direction, and is re¬ tracted vigorously when stretched. It possesses consider¬ able resistance, or in common language is tough. The experiments of Clifton Wintringham show that it sustains a considerable weight without breaking, and that this toughness is greater in early life, or in the veins of the young subject, than at a later period.2 In short, it may be stated as a general fact, that venous tissue, though thinner, possesses greater elasticity and tenacity than ar¬ terial tissue. According to the experiments of the same inquirer, this property depends on that of the superior density of the venous tissue; the specific gravity of the matter of the vena cava being invariably greater than that of the aorta in the same subject, both in man and in brute animals. From some experiments Magendie is disposed to con¬ sider it of a fibrinous character. But it exhibits in the living body no proof of muscular structure or irritable power. When punctured by a sharp instrument, or ex¬ posed to the electric or galvanic action, it undergoes no change or sensible motion. This tunic is wanting in those divisions of the venous system termed sinuses, in which its place is supplied by portions of the hard membrane (dura meninx). 2dly, The inner surface of any vein which has been laid open and well washed is found to be smooth, highly po¬ lished, and .of a bluish or blue-white colour. This is the inner or free surface of the inner venous membrane (membrana intima). It is exceedingly thin, much more so than the corresponding arterial membrane, much more distensible and less fragile. It bears a very tight ligature without giving way as the arterial does; but it also sus¬ tains considerable weight, which shows that it is tough and resisting. This is the membrane termed by Bichat common membrane of dark or modena blood. According to the views of this anatomist, it forms the inner or free surface, not only of all the venous twigs, branches, and trunks composing this system of vessels, but it is extend¬ ed from the superior and inferior great veins over the in¬ ner surface of the right auricle and ventricle, and thence over that of the pulmonary artery and its divisions; and through this whole tract it is the same in structure and properties. This doctrine has not yet been controverted. But perhaps it may be doubted, both with regard to the inner arterial membrane, that the inner tunic of the aorta and of the pulmonary veins is quite the same; and in regard to this inner venous membrane, whether that of the veins in general is quite the same with that of the pulmonary artery. The subject demands further research. Mean¬ while strong confirmation is found in the interesting re¬ mark of Bichat, that the osseous or calcareous depositions which are common in various spots of the inner arterial 1 Diatribe Anatomico-physiologica de Slructura atque Vita Venarum.

Yg?- ANATOMY genjil membrane, and especially at the mitral and aortic valves, inatfj- are never found in the inner venous membrane, or at the ✓v-'7 tricuspid valve, or in the semilunar valves of the pulmo- V£ nary artery. Have these depositions been found inside the pulmonary veins, and not inside the pulmonary artery ? This fact is still wanting to complete even their pathologi¬ cal similarity. The inner or common venous membrane is, however, the most extensive and the most uniform of all the venous tissues. It is the only one which is found in the substance of organs, and is present where the cellular and proper membranes are wanting. This is the case not only with venous branches and minute canals as they issue from the substance of muscles, bones, and such organs as the liver, kidneys, spleen, &c., but is also very remarkably observed with regard to the venous canals of the brain. I have al¬ ready noticed the absence of the cellular and proper tis¬ sues in these tubes; and I have now to remark, that the cerebral veins consist solely of the inner membrane while in the brain or membranes, and when in the sinuses, of this inner membrane, placed between two folds of the dura mater. When the jugular vein reaches the temporo- occipital sinuosity, it loses its proper membrane, while its common or inner membrane passes into the hollow of the dura mater, called sinus, and thus forms the venous canal. This fact is readily demonstrated by slitting open either the lateral or the superior longitudinal sinus, when a thin delicate membrane, quite distinct from the fibrous appear¬ ance of the dura mater, will be found to line the interior of these canals. The inner surface of many veins presents membranous folds projecting obliquely into the cavity of the vessel. These folds, which, from their mechanical office, have been named valves (valvulce), are parabolic in shape, have two margins, an attached and free,—and two surfaces, a con¬ cave turned to the cardiac end of the vein, and a convex turned in the opposite direction. The attached margin is not straight, as may be imagined, but circular, and ad¬ heres to the inner surface of the vessel. The free margin resembles in shape an oblong parabola; and the direction of the valve is such, that a force applied to its convex sur¬ face would urge it more closely to the vein, whereas a force applied to the concave surface would either oblite¬ rate the circular area of the vessel, tear the valve from the vein, or otherwise meet with resistance. The size of the valves is variable. In some instances they are sufficiently large to fill the canal of the vessel, and in others they are too small to produce this effect. The obliteration of the circular area of the vessel is most perfect when there are two or three at the same point. Bichat ascribed the variable state of this quality to the dilated or contracted condition of the veins at the moment of death. This, however, is denied by Magendie. In structure these valvular or parabolic folds are said to consist of a doubling, or two-fold layer of the inner membrane; and with this statement no fact of which we are aware is at variance. A hard prominent line, which generally marks the attachment of their fixed margin to the vein, is asserted by Bichat to consist of the proper ven¬ ous tissue, the fibres of which, he says, alter their direc¬ tion for this purpose; and when the common or inner membrane reaches this line, it doubles or folds itself to I form the valve, which thus consists of two layers of the inner or common membrane. This, however, is denied by Hunter,1 who considers them of a tendinous nature, and by Gordon, who made several unsuccessful attempts to split these two layers.2 Valves are not uniformly present in all veins. They are found, 1st, in the following branches of the superior o-reat vem—the interna! jugular, the azygos, the facial veins, those of the arms, &c.; 2d, in the following branches of the inferior great vein—the divisions of the posterior iliac, of the femoral, tibial, internal and external saphena, and m the spermatic veins of the male. They are wanting in the trunk of the inferior great vein (cava inferior), in the renal, mesenteric, and other abdo¬ minal veins, in the portal vein, in the cerebral sinuses, in the veins of the brain and spinal chord, in the veins of the heart, of the womb generally, and of the ovaries, and per¬ haps in all other veins less than a line in diameter.3 In the cerebral sinuses the transverse chords are supposed to supply their place. In the lungs they were supposed to be wanting, till their presence was established by Mayer of Bonn. In situation the valves vary considerably. In general they are found in those parts of venous canals at which a small vein opens into a larger. But even from this ar¬ rangement there are deviations. The only valve which is definite and invariable in its situation is the Eustachian (valvula Eustachiana, valvula nobilis), which is always placed at the cardiac end or beginning of the inferior cava, where that vessel is attached to the sinus of the right auricle. Shaped in general like a crescent, the at¬ tached margin of which is the arch of a large circle, and the free that of a small one, it proceeds from the left ex¬ tremity of the sinus downwards, forwards, and towards the left side, where it is insensibly lost on the membrane of the auricular septum. At its lower end it generally covers the orifice of the large coronary vein. This mem¬ branous production is always larger, more perfect, and more distinct in the foetus and in the infant, than in the adult. In the latter it is almost always reticulated; and sometimes the only vestige of its existence is a thin chord or two representing its anterior margin. I have seen it reticulated even at the age of sixteen or seventeen, and almost destroyed beyond thirty. Haller was much per¬ plexed to account for the use of this membranous fold.4 The conjecture of Bichat, that it is connected with some purpose in the foetal circulation, is entitled to regard. Dr Gordon mentions a third partial substance, which is occasionally found in local patches at various parts of veins. I have never met with this, and believe it to be accidental, or not connected with healthy structure. Besides the cellular or filamentous envelope, veins re¬ ceive capillary arteries, to which there are corresponding veins. The arteries rise from the nearest small ramifying arteries ; and the corresponding veins do not terminate in the cavity of the vein to which they belong, but pass off from its body, and join some others from different parts; and at last terminate in the common trunk somewhere higher.5 Nervous branches, or rather filaments, are ob¬ served in the pulmonary artery and great veins only. Are they derived from the great sympathetic, as is generally said ? In the veins, as in the arteries, the anatomist recog¬ nises two extremities, the cardiac or collected, and the organic or the ramified. Examined physiologically, how¬ ever, the terms origin and termination are not of the same import as when applied to the arteries. In reference to the veins, they become convertible terms; and it is the 721 General Anatomy. Vein. 1 x.

General usage even of writers on anatomy to represent the veins Anatomy. as arising where the arteries terminate, and terminating Ve:n a.^ ^le orSan from which the latter arise. This distinc¬ tion must be kept in view in the following observations. The cardiac extremity or termination of the veins is so well known as to render any minute explanation unne¬ cessary. The organic extremity or origin of the venous system is more obscure and difficult to be understood. It is in¬ deed impossible to trace the origin of the small venous ves¬ sels, unless in the manner in which Leeuwenhoeck,1 Wil¬ liam Cowper,2 Henry Baker,3 Haller, and Spallanzani,4 did in their observations on the transparent parts of animals ■ in general cold-blooded. From the experiments of these observers, we know that a very small vessel, evidently tending and conveying blood towards a larger, connected with a venous branch, may be seen passing directly from a similar small vessel, as evidently conveying blood//'om a larger, which is connected with the arterial system. All that we know from this, however, is, that a vein contain¬ ing red blood may rise from an artery conveying red blood. This is matter of pure observation ; and all beyond is little more than conjectural. Haller, indeed, admits origins of veins as manifold as the terminations of the arterial system, a view in which he has been followed by almost all subsequent authors ; and Bichat states it as a leading proposition, that the veins arise from the general capillary system. Neither conclu¬ sion is founded on strict observation; and while that of the former physiologist is derived chiefly from uncertain facts and loose analogies, the statement of the latter is too hypothetical and general to be either entirely true or wholly false. Of one fact only are we certain. The blood which is conveyed into the small vessels and the substance of the tissues and organs is brought back by the veins. We have seen that the only origin which is strictly susceptible of demonstration is that of the red vein from the red artery. The point then to be ascertained is, whether colourless veins and absorbent veins arise from the several textures, as colourless and exhalant arteries terminate in them. The proper place for the further examination of this ques¬ tion is the subsequent section. I must not omit to mention, nevertheless, that the veins have been shown to be connected at their ramified extremities with the lymphatics. When the veins become distinct vessels, branches, and trunks, they become once more objects of sensible exami¬ nation. In their course from their organic to their cardiac extremities they present various circumstances which merit attention. 1. In general every artery is accompanied by a venous tube, which is divided in the same manner, and furnishes or receives an equal number of branches. Thus the de¬ scending aorta is accompanied by the vena cava inferior ; the common iliac arteries by common iliac veins ; the an¬ terior iliac, femoral, and popliteal, by anterior iliac, femoral and popliteal veins. These veins are deep-seated, and are generally named the concomitant veins (vents comites vel vena: satellites). In some situations an artery may be ac¬ companied either in its trunk or in its branches by two veins ot equal size. Thus in general the brachial artery, and its branches the radial and ulnar, are each accom- Gem panied by two veins. The only situations in which the Anau r. number of veins can be said to be exactly equal to that ofv-^v ■> the arteries, are in the stomach, in the intestinal canal, Vei in the spleen, in the kidneys, in the testicles, and in the ovaries. 2. In the extremities and in the external regions of the trunk we find, in addition to the concomitant veins, an external layer of venous tubes immediately beneath the skin, (vena: subter cutem disperses, Pliny). These subcuta¬ neous or superficial veins do not correspond to any ar¬ tery; but as they are chiefly destined to convey the blood from the skin and other superficial parts, they open into the deep-seated veins. Thus in the case of the ba¬ silic and cephalic, two superficial veins of the arm, the former, after passing the bicipital fascia, forms in the sheath the brachial vein; and becoming the axillary in the axilla, receives the latter vessel. In the same manner the saphena ffapjjwjj, vena manifesto), or superfi¬ cial vein of the leg, passes through the falciform process of the fascia lata to join the femoral vein. From this it results that the venous canals are on the whole more numerous than the arterial. In a few situa¬ tions only a single vein corresponds to two arteries, as in the penis, the clitoris, the gall-bladder, and the umbilical chord. Often also in the renal capsules and the kidneys two or more arteries have only one corresponding vein. In such circumstances the vein is always large and capa¬ cious. It has been generally stated that the calibre and area of the venous tubes are much larger than those of the corresponding arteries, and consequently that the capaci¬ ty of the venous system is much greater than that of the arterial. I acknowledge that I know not on what exact evidence the former of these propositions, the only one with which the anatomist is concerned, is made to rest. If it be mere inspection in the dead subject, or the effects of injection, little doubt can be entertained that the al¬ leged greater calibre depends chiefly on the laxityand dis¬ tensible nature of the venous fibre. The arterial tubes ap¬ pear small in consequence of annular contraction, or the ten¬ dency which they have to collapse, when the distending force has ceased to operate. The venous canals appear large by reason of their distension and distensibility dur¬ ing life, from the tendency to accumulation in their branches in most kinds of death, except that by hemor¬ rhage, and from a smaller degree of the physical property of shrinking and annular contraction when empty. When a vascular sheath is exposed in the human sub¬ ject, as in the operation for aneurism, or in the lower ani¬ mals in the way of experiment, the vein generally ap¬ pears larger than the corresponding*artery. This, how¬ ever, is never so considerable as it is represented by most authors, and certainly cannot afford grounds for the estimates which Keill, Jurin, and other mathematical physiologists have assigned to the relative capacity of the arteries and veins. It is also to be observed that some¬ thing of this greater size depends on the increase ot dila¬ tation resulting from removing the pressure of incumbent parts. In young animals also the difference between the size of the veins and their corresponding arteries is so trifling as to be scarcely discernible. This shows that 1 Arcana Naturae Detecta: Opera Omnia, tom. ii. p. 1G0, 1G8. 1 hilusophical Transactions, No. 280, p. 1170. Cowper saw this communication of arteries and veins not only in cold-blooded ani¬ mals, as the lizard, tadpole, and fishes, but in the omentum of a young cat and a dog. 3 On Microscopes, and the discoveries made thereby.

General this theory, for little of it is matter of strict observation, Anatomy. rests on very hypothetical grounds. Of the different kinds of terminations assigned to api anes'ar^erjeSj anci 0f origins assigned to veins, one only ad¬ mits of sensible demonstration.. Arteries, when they have so much diminished as to become capillary, are seen by the microscope, in some instances by the naked eye, to pass directly into corresponding capillary veins, or to end abruptly in some organ or membrane unconnected with any other vessel.1 It is likewise certain that the microscope shows every capillary vein to arise from a capillary artery; and if there be any other mode of origin, it has not yet been demonstrated.2 Only one other circumstance requires to be taken into account in this inquiry. This is, that the capillary artery and vein may contain either red or colourless blood; for, ac¬ cording to the size of the vessels, and the nature of the organs or tissues in which they are distributed, the blood which flows through them will be coloured or colourless. This view of the communication of minute arteries and veins, which is perfectly consistent with the known facts, affords the only explanation which it is possible to give, of the singular division of the capillary system which Bichat has chosen. This author considers the capillary system under three general heads: Is#, In organs in which it contains blood only, for instance, in the muscles, the spleen, some parts of the mucous membranes ; 2c#, in organs in which it con¬ tains blood and other fluids, for example, in bone, cellu¬ lar tissue, serous membrane, part of the fibrous system, the skin, the vascular parietes, glands, &c.; and, 3c#, in organs in which it contains no blood, the instances of which are, tendon, cartilage, ligament, hair, &c. Now, it is of little consequence to say that the tissues of the two last divisions contain other fluids than blood, when we are also told that the phenomena of injections, which prove that their capillaries communicate directly with arteries conveying red blood, the effect of irritating applications mechanical or chemical, and the phenomena of acute or chronic inflammation, show that they may receive and convey red blood. The conclusion of this in common language is, that the capillary arteries and veins of the second order of tissues do not all contain red blood, but that many of them contain a colourless part of that fluid; and that all the capillary arteries and veins of the third order of tissues convey in the natural state colour¬ less blood only. What then is the precise idea which ought to be formed of the intermediate system which Bichat conceived to exist between the minute arteries and veins, or what have been termed the venous radiculcc, ? From the present state of facts it results that nothing more can be admitted to constitute the capillary system than those minute vessels, whether conveying coloured or colourless blood, in which inspection, microscopic observa¬ tion, and injections show that arterial branches at once terminate, and minute veins (radiculce venosce) have their origin. It is clear that, physiologically speaking, these vessels can neither be regarded as arteries nor as veins strictly; for the characters on which this distinction is founded are necessarily obliterated in this system of ves¬ sels. There is no precise point at which the arterial tissue can be said to terminate, and none at which the venous structure can be said to commence. Here inspection or microscopic observation affords little or no aid; for the vessels are too small to allow their structure to be ex¬ amined correctly. If, however, we adopt the doctrines of Bichat with regard to the inner arterial and venous tunics G,eral my forming the ultimate tube of small arteries and small M*' veins, we must conclude that the arterial membrane is^ lost in the venous, and that the common membraneCa»rtie of red blood is identified with the common membrane of dark or modena blood. This conclusion involves no¬ thing absurd or improbable, and, though not founded on observation, it is more natural than many similar ideas which have been formed on the nature of this system of vessels. It may be added, that it is not at variance with what is observed in these vessels in the living body. It is found that the blood in a minute artery is not of the bright red colour which it possesses in the trunk and large branch from which the minute artery derives its blood, but is gradually acquiring the dark hue which be¬ longs to the blood of the venous branches and trunks. By some, however, this direct communication of minute arteries and veins is denied. Thus, according to Doellin- ger, the arteries at their last ramifications are void of proper membranous walls; the blood moves in immediate contact with the solid matter of the body, which is in truth the fundamental or penetrating filamentous tissue; and from this it passes into the venous tubes and lympha¬ tics, which also arise from this substance. According to Wilbrand, again, who equally denies this direct communication of arteries and veins, all the blood is converted into organic fibres and secretions; and these organic fibres, becoming gradually fluid, are converted into blood and lymph, which continue the circulation. These notions are too fanciful and too incapable of de¬ monstration to become the object of serious attention to the anatomist. It is of little moment whether the vessels in the ultimate ramifications possess tunics or not. When they cease to possess tunics they cease to be vessels; and to carry observation beyond this point is either impracticable or useless. In other respects the investigation of this point belongs to the subject of the exhalant vessels. Bichat describes two great capillary systems in the human body: Is#, The general one, or that which con¬ sists of the minute terminations of the aortic divisions, and the origins of the superior and inferior great veins; and, 2d, the pulmonary capillary system, or that which consists of the minute terminations of the pulmonary ar¬ tery, and the origins of the pulmonary veins. It is evi¬ dent that the manner in which the first of these systems is here represented communicates a very incorrect idea of its true character, and that there is in truth an indi¬ vidual capillary system, not only for every organ, but in some instances for every tissue. The brain possesses an individual capillary system; and that of the membranes is evidently distinct from that belonging to the organ it¬ self. The heart and the kidneys possess each an indivi¬ dual capillary system; and the liver may be said to have two, one formed by the communication of the hepatic ar¬ tery and veins, and another consisting of the divisions of the portal vein, with the branches of the hepatic hollow vein ; ( Vena cava hepatica). The organic properties of the capillary vessels are as little known as their structure. Many physiological and pathological writers, especially experimentalists, have ascribed to them a power which has at different times been called muscular, tonic, irritable, contractile; and have asserted that, because the larger arteries are pro¬ vided with a fibrous membrane, which they have called muscular, and to which they have ascribed irritability, or the power of contraction when stimulated, their minute or 1 Gordon, p. 5G. 51 Ibid, p 26. 725 A N A r Gi ral capillary terminations must have the same property. This Ani.ray- conclusion is completely unfounded for two reasons. 1st, vr >~/1 have already shown that the proper arterial tunic is not Cap.nes-muscular in structure, and, according to the best experi¬ ments, possesses no property of contraction when stimu¬ lated. 2d, Although it be admitted that the proper arte¬ rial tissue is muscular and irritable, it is quite certain that observation has not hitherto shown that this tunic can be recognised in arteries smaller than a line in diameter; and in the capillaries properly so called, that is, in vessels which partake of the nature of artery and vein, no such structure has yet been observed. It is not improbable, however, that the capillaries pos¬ sess certain organic or vital properties; but all that has been taught on this subject is either hypothetical or de¬ rived from an insufficient and imperfect collection of facts. It is certain that the blood which moves through them is beyond the direct influence of the action of the heart, and can be affected by this only so far as it keeps the larger vessels constantly distended with a column of blood which cannot retrograde, and must therefore move forward in the only direction left to it. It has been therefore argued that the capillaries must have an inherent power of contraction, by which this motion is favoured. Is it not sufficient to say that they act merely as resisting canals, to prevent their contents from escaping, and to minister to the various tissues and organs those supplies of blood which the several processes of nutrition, secretion, &c. re¬ quire ? The effects which the application of mechanical irri¬ tants, or chemical substances, as alcohol, acids, and alka¬ lies, produced in the experiments of Hunter, Wilson Philip, Thomson, and Hastings, have been supposed to demon¬ strate the irritable nature of the capillary vessels. The conclusion is illegitimate, in so far as the results of these experiments are open to several sources of fallacy. In some instances these effects are to be ascribed to incipient inflammation, in others to shrivelling of the capillary struc¬ ture, or crispation by chemical action, in others to actual coagulation of the blood of the capillaries; but none of them prove satisfactorily any peculiar properties in the vessels of which the capillary system is composed. While the views of Reuss, and the recent experiments of Dutrochet and Wedemeyer, render it probable that the capillaries possess some contractile power, they by no means prove that this is adequate to impel the blood through them, independently of the impulse of the heart. According to the hypothesis of Reuss, the arterial system is in a state of positive, and the venous in that of negative, electricity; and by the operation of this agent the blood is made to move from the former class of vessels through the capillaries into the latter. From the experiments of Dutrochet, again, on the transmission of fluids through organic membranes, that author infers that, by means of the inward and outward impulse, or that property which he denominates Endosmose and Exosmose, the blood flows through the capillaries into the veins. Lastly, Wedemeyer, who further maintains that the impulsive force of the mart is propagated to the capillary system, concludes, trom the effects of injecting fluids, both mild and irrita- tive, and from microscopic observation, combined with the effects of mechanical and chemical irritants, that the ca¬ pillaries possess considerable contractile power, the ope- r O M Y. ration of which is under the influence of galvanism, or General nervous energy, or both; but that this, instead of pro- Anatomy, motmg, ought to resist the motion of the blood through them. & Erectile Tissue. ( Vasa Erigentia,— Vascula Erectilia,— Tissu Erectile?) The system of capillary arteries and veins does not pre-Erectile sent the same arrangement in all situations and in all thevessels- tissues of the human body. A peculiar arrangement of these vessels was early recognised by our countryman William Cowper, who states that he demonstrated the direct com¬ munication of arterial and venous canals, not only in the lungs, but in the spleen and penis, “ in which,” says he, “ I have found these communications more open than in other parts.”1 This fact, however, was long overlooked by subsequent anatomists. Among the terminations of arteries enumerated by Hal¬ ler, one which he referred to the head of exhalants was that of a red artery or arteries pouring their blood into the spongy or cellular structure of the cavernous bodies of the nipple, the clitoris, and the penis, that of the wat¬ tles of the turkey, and the comb of the cock.2 His detail¬ ed examination of those parts shows, that, with a correct knowledge of their anatomical structure, he had not a very distinct conception of the manner in which their ves¬ sels are disposed. It was afterwards pbserved, however, by John Hunter, that the spongy structure of the urethra and glans consists of a plexus of veins. Bichat remarked that the spleen, and the cavernous body of the penis, instead of presenting, as the serous surfaces, a vascular or capillary net-work, in which the blood oscillates in different directions according to the im¬ pulse which it receives, exhibit only spongy or lamellar tissues, still little known in their structure, in which the blood appears often to stagnate instead of moving. As this peculiar structure was known in the cavernous body to be the seat of a motion long known by the name of erection, MM. Dupuytren and Richerand distinguished this arrangement of arteries and veins as a peculiar tissue, under the name of erectile,—a distinction which, though partly understood before, has only now been admitted as well founded in the writings of anatomical authors. Ac¬ cording to the recent arrangements of M. Beclard this tissue comprehends not only the structure of the cavernous body, but that of the spongy substance (corpus spongiosum?), which incloses the urethra, and forms its two extremities, the bulb and gland, the clitoris, the nymphoe, and the nip¬ ple of the female, the structure of the spleen in both sexes, and even that of the lips.3 4 It is unfortunate that the researches of anatomists on this erectile tissue have been restricted chiefly to the spongy body of the urethra and the cavernous body of the penis; and it is rather by analogy than direct proof that similarity of structure between them and the other parts referred to the same head is maintained. I shall here state what is ascertained. The cavernous body of the urethra, or what is now termed its spongy body? is represented by Haller to con¬ sist of fibres and plates issuing from the inner surface of the containing membrane, and mutually interlacing, so as to form a series of communicating cells,5 into which the 3 Philotophical Transactions, No* 285, p. 1386. 2 Elementa Physiologice, lib. ii. sect. 1, § 24. 4 ^d, their termination on the surfaces of serous and mucous mem¬ branes, and the outer surface of the corion or true skin. The exhalant vessels, the existence, origin, and termi¬ nation of which he thus proved, he distinguished into three classes. The first contains those exhalants which are concerned in the production of the fluids which are immediately removed from the body,—the cutaneous and the mucous exhalants ; the second contains those exhal¬ ants which are employed in the formation of fluids which, continuing a given time on various membranous surfaces, are believed to be finally taken again into the circulation by means of absorption; and the third class consists of the exhalants concerned in the process of depositing nu¬ tritious matter in the different tissues and organs of the human frame. This arrangement is more distinctly seen in the following table. T. Exterior, opening on natural surfaces or / Cutaneous, canals... f Mucous. f Serous. 2.

Each organic tissue is in this system supposed to have its appropriate exhalant arteries, from which it derives the material requisite for its nutrition. The clearness and regularity of this arrangement would render it desirable that the existence of these vessels were demonstrated with certainty. It is evident, how¬ ever, that the regularity of arrangement is the only ad¬ vantage which it possesses over the views of those authors whose method and opinions Bichat professed not to follow. The existence of exhalants is as little proved 1 Brevis Expositio Doetrinas Physiologicce de Turgore Vitali, 1795. Ab Ernesto B. G. Hebenstreit, M.D. &c.

General in the rigorous reasoning of Bichat as in the fanciful Anatomy, theories of Boerhaave, the generalizing conclusions of Haller, or the bold supposition of lateral porosities by ' Mascagni. This defect in his system has therefore been recognised recently both by Magendie and Beclard, the first of whom, though he admits the existence of exhala¬ tion as a process of the living body, allows that no expla¬ nation of its mechanism or material cause has been given, and asserts that Bichat has created the system of vessels termed exhalants; while the second thinks that anato¬ mical observation furnishes no evidence of their existence. The colourless capillaries, he observes, which are admit¬ ted by all, and the existence of which is satisfactorily esta¬ blished by the well-known experiment of Bleuland, proves nothing whatever concerning the existence of exhalant vessels; for these colourless arteries are observed to ter¬ minate in colourless veins, and there is no proof hitherto adduced of their proceeding further, or terminating by open mouths. He admits that the fact of exhalations in the living body, of nutrition, of transudation by arterial extremities, shows that these extremities possess openings through which the fluids of exhalation, the materials of nutrition, and the matter of injection, escape. But whe¬ ther these openings are found at the point at which the capillary arteries are continuous with veins, or belong to a distinct order of vessels continued beyond these arte¬ ries, is a question which observation has not yet deter¬ mined, and which it perhaps is unable to determine. Such is the present state of knowledge in relation to the existence of exhalant arteries. While the process of ex¬ halation is admitted, we must avow, as Cruikshank did long ago, that we are unable to prove satisfactorily the existence of any set of vessels, or any mechanism by which it might be accomplished. Lymphatic System. ( Vasa Lymphatica, Vasa Lymphifera, Lymphce-Ductus of Glisson and Jolyffe,—Systeme Ab- sorbant,—Die Saugadern.) Lympha- in most situations of the human body, and especially in the vicinity of arterial and venous trunks, there are found long, slender, hollow tubes, pellucid or reddish, which present numerous knots, joints, or swellings in their course, and to which the name of lymphatics or absorb¬ ents has been given. It is most expedient to employ the former appellation only, as the latter implies the perform¬ ance of a function, the reality of which has been much questioned of late years. Though Eustachius had seen the thoracic duct in the horse, and some slight traces of a knowledge of vascular tubes, different either from arteries or veins, are found in the writings of Nicolaus Massa, Fallopius, and Veslin- gius, the merit of establishing their existence is generally ascribed to Caspar Asellius, a physician of Pavia. This anatomist, who had in 1622 seen the white-coloured tubes, then first named lacteals, issuing from the intestines of the dog, observed also a cluster of vessels less opaque near the portal eminences of the liver,—an observation which he afterwards repeated in the horse and other quadrupeds. The same vessels were also described and delineated by Highmore.

Paris, 1787, folio. nv. r Walaeus and Van Horne, the first exact information after Ge w Asellius is that which relates to Olaus Rudbeck, who, in AnaLy. 1650, is said to have seen them in a calf, and to have de-^i monstrated the thoracic duct, and the dilated sac, after-^'Vn wards termed receptacidum chyli. Glisson informs us that Jolyffe had in 1652 imparted to him the knowledge of a set of vessels different from arteries and veins; and it appears, from the testimony of Wharton, that Jolyffe had demonstrated these vessels in 1650.1 In short, the discovery of lymphatics, and the correction of some errors of Asellius, are ascribed to the English anatomist, not only by Wharton and Glisson, but by Charleton, Plott, Wotton, and Boyle. The existence of these vessels, thus partially demon¬ strated, was afterwards more fully established by the re¬ searches of Bartholin, Pecquet, Bilsius, Nuck, the second Monro, and Haller. It is chiefly to the exertions of William Hunter, and his pupils Hewson,2 Sheldon,3 and Cruikshank,4 in this country, and to those of Mascagni5 in Italy, that the anatomical world are indebted for the com¬ plete examination and history of this system of vessels. The lymphatic vessels consist, in the members, of two layers, a superficial and a deep-seated one. The first is situate in the subcutaneous cellular tissue, between the skin and the aponeurotic sheaths, and accompanies the subcutaneous veins, or creeps in the intervals between them. A successful injection of these superficial lym¬ phatics will show an extensive net-work of mercurial tubes surrounding the whole limb. The deep-seated layer of lymphatics is found chiefly in the intervals between the muscles, and along the course of the arterial and venous trunks. In tracing both layers of lymphatics to the upper, fixed, or attached end of the members, we find they increase in volume and diminish in number. At the connection of the members with the trunk, they are observed to pass through certain spheroidal or spherical bodies, termed lymphatic glands or ganglions. The lymphatics of the upper extremity, after passing through the glands of the armpit, terminate in trunks, which open into the subclavio-jugular veins, one on each side of the neck. Those of the lower extremity, after passing through the glands of the groin, proceed with the common iliac vein into the abdomen, where they unite with other lymphatics. The lymphatics of the trunk consist in like manner of two layers, a subcutaneous and deeper seated one, dis¬ tributed in the chest between the muscles and pleura, and in the abdomen between the muscles and peritoneum. In the chest and belly, each organ possesses a superficial layer of lymphatics distributed over its surface, and per¬ taining to its membranous envelope; the other ramifying through its surface, and pertaining to the peculiar tissue of the organ. This twofold arrangement is most easily seen in the lungs, the heart, the liver, spleen, and kidneys. In a similar manner are arranged the lymphatics in the external parts of the scull; on the face, where they are very numerous; in the spaces between the muscles; and on the neck, in which they pass through numerous glands. No lymphatics, however, have been found in the brain, the spinal chord, their membranous envelopes, the eye, or the ear. See also Prodromo, Sec- ANATOMY. 729 gc al All the lymphatics hitherto known terminate in two ^nainy- principal trunks. One of these, termed from its site thoracic duct (ductus thoracicus, die Milchbrustrdhre, le ca- tF1* ml thoracique), is situate on the left side of the dorsal ^ vertebrae. It receives the lymphatics of the lower extre¬ mities, of the belly, and the parts contained in it; those of great part of the chest, and those of the left side of the head, neck, and trunk, and left upper extremity. The other lymphatic trunk, which is situate on the right side of the upper dorsal vertebrae, is formed by the union of the lymphatics of the right side of the head, neck, right upper extremity, and some of those of the chest. Both of these trunks open into the subclavio-jugular vein of each side. That lymphatics terminate in branches of the venous system, has been asserted on the authority of various ob¬ servers. Steno, for instance, states that he traced the lymphatics from the right side of the head, the chest, and pectoral extremity, in animals, into the right axillary vein ; and he gives delineations of anastomotic connections of several lymphatics with the axillary and jugular veins. Similar facts have been reported by Nuck, Richard Hale, Bartholin, and Hartmann. Ruysch traced the lymphatics of the lung into the subclavian and axillary veins; Dre- lincourt those of the thymus gland in animals into the subclavians; and Hebenstreit saw those of the loins pass into the vena azygos. Haller, though unwilling to deny the testimony of these observers, considers it liable to various sources of fallacy, and doubts the direct communication of the lymphatic and venous systems. By John F. Meckel the grandfather*, nevertheless, this communication was maintained, from the circumstance that he found mercury injected into the lymphatics pass into the veins without any traces of ex¬ travasation. From injecting the lymphatics also he found the inferior cava full of mercury, not a particle of which had passed by the thoracic duct into the superior cava. In¬ jecting afterwards an indurated lumbar gland from a pel¬ vic lymphatic, when he found its lower half only was filled, he increased the pressure, with the view of filling the minute vessels of the gland. When this was con¬ tinued a little, he observed the fluid metal pass into the inferior cava, and thus traced the minute lymphatics into tire venous system.1 These facts have received too little attention, from the circumstance that Hewson, though not doubting them as stated by the author, regarded them as liable to consi¬ derable fallacy, and, along with William Hunter, imputed the effect in question entirely to extravasation. Both Hunter and Hewson, indeed, appear to have injected veins from lymphatics in the same manner in which Meckel did; but both saw reason to infer that extravasation had taken place. Cruikshank, again, states that he never saw a lymphatic vessel inserted into any other red veins than the subclavians and jugulars. The termination re¬ marked by Steno and his successors constitutes in truth the common trunk or lymphatic vein admitted by Cruik¬ shank,—a thoracic duct of the right side. Recently this mode of termination has been revived by Tiedemann and Fohmann,2 who state that, in the seal, the lactiferous vessels communicate with veins arising from the mesenteric glands, and pass thence into the venous trunks without proceeding through the thoracic duct. General M. Lauth junior, of Strasburg, again, conceives that he Anatomy, has demonstrated that lymphatics communicate with veins within the substance of organs, and in the interior of the Hympha- lymphatic glands;3 an inference which at present requirestlC3' further verification. The statements of Lippi of Florence,4 that every lymphatic almost communicates freely with ve¬ nous tubes, is still more improbable, and has been rendered exceedingly doubtful by the recent researches of Rossi.5 The connections of the ends of lymphatics with the or¬ gans and tissues from which they arise, termed their ori- gins, are completely unknown. In some favourable in¬ stances the lymphatics of the intestinal canal are so filled with a reddish or whitish fluid after the process of diges¬ tion has continued for some time, that not only are their larger branches easily seen, but by the aid of the micro¬ scope some of the smaller may be traced to their com¬ mencement. This, which was ascertained by Cruikshank (p. 55 and 58), and confirmed by Hewson, Bleuland, and Hedwig, has been contradicted by the observations of Ru- dolphi and Albert Meckel. In all other parts, however, though a successful injection may show the course and distribution of many of the smallest lymphatics, yet no ori¬ fices are perceptible at the point at which they seem to stop, and we are uncertain whether these points are their ori¬ gins. (Cruikshank.) Mere observation is here as un¬ availing as in regard to the termination of exhalants. The continuation of lymphatics with arteries, unless in the case of those which arise from the interior of arterial tubes (Lauth), is not satisfactorily established. It has been conjectured, however, that their ends or imperceptible origins are connected to the tissues to which they are traced, and that the lymphatics arise in this manner from these tissues. The lymphatics are distinguished by being in general cylindrical in figure, and by varying in calibre at short spaces. In this respect they differ from the arteries and veins. It has been further justly remarked by Gordon, that the middle-sized lymphatics are remarkably distin¬ guished from the corresponding parts of the arterial and venous system by three peculiarities: ls£, When two lymphatics unite to form a third, the trunk thus formed is seldom or never larger than either of them separately; 2dly, their anastomoses with each other are continual; and, 3dly, they seldom go a great space without first di¬ viding into branches, and then reuniting into trunks. The outer surface of a lymphatic is filamentous and rough, the inner smooth and polished, like that of small veins. It is impossible to observe the structure of these tubes in the middle-sized, or even in the large lympha¬ tics ; and anatomists have generally been satisfied with supposing that the structure of all of them is similar to that of the thoracic duct, or some other large vessels equally susceptible of examination. According to the ob¬ servations of Cruikshank (chap, xii.), which have been verified by Bichat, the thoracic duct presents, ls£, a layer of dense, firm, filamentous or cellular tissue, exactly simi¬ lar to that found inclosing arterial and venous tubes, which the latter regards as foreign to the vessel, but giv¬ ing it a great degree of support and protection; 2dly, a proper membrane, delicate, transparent, and moistened inside by an unctuous fluid, which he seems inclined to 1 Nova Experimenta et Obscrvationcs dr finibus Venarum ac Vasorum Lymphaticorum, sect. 1, p. 4.

Their existence, though admit¬ ted by Schreger and Soemmering, is denied by Mascagni, Rudolphi, and J. F. Meckel, and, I may add, by Bichat and Beclard. This account differs not much from that of Dr Gordon, who could not recognise distinctly more than one coat, similar to the inner coat of veins. The fila¬ mentous layer noticed by Bichat, and considered by Mas¬ cagni as an external coat, is of course excluded. The knotted or jointed appearance of lymphatics is oc¬ casioned chiefly by short membranous folds in their ca¬ vity, called valves. These folds are thinner than the ve¬ nous valves; but they are equally strong, and have the same shape and mode of attachment to the inside of the vessel. They are generally found in pairs, but never three at the same point. A single valve is sometimes found at the junction of a large branch with a trunk, or of a trunk with a vein. According to Cruikshank, there is considerable variety in the distribution of valves; but in general a pair of valves will be found at every one-twentieth of an inch in lymphatics of middling size. In the larger lymphatics they are less numerous than in the small. The structure of these valvular folds is as little known as that of the inner membrane, of which they appear to be prolongations. According to Mascagni, they sometimes contain a small portion of fine adipose substance. The tissue which forms the lymphatic tubes is strong, dense, and resisting; and from the weight of mercury which they bear without rupture, it has been generally concluded that they are stronger in proportion to their size than veins. This tissue also possesses considerable elasticity. The opposite states of lymphatics during digestion and after long fasting, and the phenomena of mercurial injec¬ tions, prove that the tissue of which they consist is dis¬ tensible and contractile. Though it does not exhibit ap¬ pearances of muscular structure, it has been long sup¬ posed to be endowed with a property analogous to irrita¬ bility. Such is the inference which Hunter, Hewson, Cruikshank, and others, have derived from various phe¬ nomena in the living and recently dead tissue. Though Bichat doubts what he terms organic sen¬ sible contractility, yet he admits insensible contractility as necessary to the functions ascribed to lymphatics. Previous to his time Schreger, in different experiments, observed the first of these qualities, in consequence of the application not only of acids, butter of antimony, and alcohol, but even of hot water and cold air. Similar con¬ tractions and relaxations have been induced by mechani¬ cal irritation. Such phenomena are observed not only during life, but even after death; and if to this we add, that the thoracic duct is often after death large and flaccid, though empty, but in the living body is almost always contracted and scarcely visible, and that a por¬ tion of it included between two ligatures, and punctured, quickly expels its contents, it may be inferred that the lymphatic tissue possesses a considerable degree of this organic property. Lymphatic Gland or Ganglion, Kernel. ( Glandules Lym¬ phatics,— Glandules Conglohata:,—Die Saugader-Drii- sen.) Lymphatic This is the proper place to consider the structure of those glands. bodies which are in common language termed kernels, to which anatomists have applied the name of lymphatic glands, and the French anatomists have more recently given that of lymphatic ganglions. The usual appear¬ ance, figure, and situation of these bodies are well known, q er In general they are spheroidal, seldom quite globular, and Ai A most commonly their shape is that of a flattened spheroid. In different subjects, and in subjects at different agesA’W they vary from two or three lines to an inch in diameter.gla|i'I The medium rate is about half an inch. Their surface is smooth; their colour grayish-pink, sometimes pale red, bluish, or of a peach-blossom tinge,—varieties which seem to depend on degrees of bloody transudation; for, when washed and slightly macerated, they assume the gray or whitish-blue colour. In a few instances they are jet black,—a peculiarity which seems to depend on a degree of black infiltration, or on the incipient stage of that change which has been termed melanosis, or melanotic de¬ position. The idea that it may be derived from the car¬ bonaceous matter suspended in the atmosphere of great cities, has been shown by Cruikshank to be absurd. Its anatomical possibility may be justly questioned. They are always situate in the celluloso-adipose tissue found in the flexures of the joints. They are found in small number at the bend of the ham, and that of the el¬ bow; in the armpit and groin they are more numerous; in considerable number in the cellular tissue of the lum¬ bar region, before the psoas and iliacus muscles; and they are most abundant round the neck. The posterior me¬ diastinum, and the cellular tissue between the mesentery and vertebral column, abound with lymphatic glands mu¬ tually connected in clusters. Each gland may be said to consist of a peculiar sub¬ stance, inclosed in a thin membrane like a capsule. The capsule is a thin, pellucid, colourless substance, which is resolved by maceration into fine whitish fibres. It is very vascular; and Mascagni appears to have detected absorb¬ ents in it. It is connected to the proper substance by fine filamentous or cellular tissue. The capsule is consi¬ dered by Beclard as a fibro-cellular membrane. The pro¬ per substance of lymphatic glands consists of a homoge¬ neous pulp, in which injections have shown numerous ra¬ mifications of minute vessels. As these vessels are in¬ jected from the lymphatics which are seen to enter the body of the gland, they are believed to be continuous with them, and to be lymphatics arranged in a peculiar man¬ ner. These vessels are of two kinds, one entering the gland, called vasa afferentia or inferentia, entrant lympha¬ tics ; the other quitting, are called vasa efferenlia, egredient lymphatics. This distinction is founded on the direction of the valves. In the vasa inferentia the free margins of the valves are turned towards the gland; in the vasa effe¬ renlia they are turned from it. The number of entrant lymphatics varies from one to thirty, and, what is more remarkable, very rarely corre¬ sponds with that of the egredient lymphatics, which are in general much fewer. Cruikshank states that he has in¬ jected fourteen entrant lymphatics to one gland, to which only one egredient vessel corresponded. When the entrant lymphatic reaches the gland, it splits into many radiated branches, which immediately sink into its substance. The egredient lymphatics are generally larger than the entrants. j The arrangement of these vessels in the interior of the glands is best described by Mascagni, whose observations are confirmed by Gordon. To see this well, it is requisite to inject the entrant lymphatics of two glands in two dif¬ ferent modes; one with mercury, the other with wax, glue, or gypsum. After a successful mercurial injection, the entrants are seen, before sinking in the gland, to di¬ vide into two orders of branches. One of them, which belongs chiefly to the surface or circumference of the gland, consists of large vessels, bent, convoluted, and in- ANATOMY. 731 i (eral terwoven in every direction, communicating with each every part and texture almnsf' nf tha UnJ u u tu i ^ .

The three orders of tubes or canals, the anatomical characters of which have now been completed, constitute what has been termed the Vascular System; (Vasa; Systema Vasorum; Das Gefass System; Le Systeme Vasculaire.) The great extent of its distribution, and the part which it performs in all the processes of the living body, both in health and during disease, must be easily understood. In every texture and organ arteries and veins are found; and in all, except a few, the art of the anatomist has demonstrated those colourless valvular tubes denominated lymphatics. The arrangement of the former, especially in the substance of the several textures, essen¬ tially constitutes what is termed the organization of these textures. Many anatomists have imagined that each tex¬ ture has a proper matter, or parenchyma, by which it was supposed to be particularly distinguished, and which was conceived to consist of minute, inorganic, solid atoms. ie lei t ns opinion be well founded or not, it is perhaps or threads mutually connected, and running in various o itt e moment to inquire.

I deviate from this practice, 1st, because I do not conceive it de¬ monstrated that the brain is the same organic substance as the nerves; 2d, because, although it were, this would not contribute to the knowledge of the minute structure of the nervous chords; 3d, because the arrangement of these chords in the animal body is inconsistent with this, and will be best understood when described separately. The nervous system of the animal body includes two general divisions. The first of these, named brain and spinal chord, is collected in a single and indivisible mass, and contained in a peculiar cavity, formed by part of the osseous system of the animal,—the vertebral column, and cranium, in the vertebrated animals generally. The second division of the nervous system, with which alone we are at present concerned, is found in the form of long chords in it is not susceptible of demonstration. The phenomena of injections, in which he . was emi¬ nently successful, led Ruysch to entertain the opinion, that every substance of the animal frame consists of nothing but vessels. This idea, though opposed by Al- To these the name of nervous trunks or chords, or simply nerves, has been long applied. The structure of the nerves has been examined with different degrees of accuracy and minuteness by a great number of anatomists.

General contain the best descriptions of the arrangement of those Anatomy. parts named ganglions and plexuses. Each nerve forms connections in three different ways. Nerves. ^ A nerve must be connected to some part of the cen¬ tral mass by one of its extremities,—the cerebral or spi¬ nal end; 2d, it must be connected to some texture or or¬ gan, or part of an organ, by the other extremity, the organic end; and, 3c?, it may be connected to other nerves by a species of junction called anastomosis (ansa), anas¬ tomosing or uniting point. By means of the first two connections, it is supposed to maintain a communication between the central mass and the several organs; and by the latter it is understood to be subservient to a more general and extensive intercourse, which is believed to be necessary in various functions and actions of the ani¬ mal system. Every nerve consists essentially of two parts; one ex¬ terior, protecting, and containing; the other interior, con¬ tained, and dynamic,1 forming the indispensable part of the nervous structure. The first of these, which has been known since the time at least of Red by the name neurilema (vjvgov e'lXsu, tiXrifia, nervi involucrum), or nerve-coat (Nervenhaut, Red; Nervenhulle, Meckel), has the form and nature of a dense membrane, not quite transparent, which is found on the outside of the nervous chord or filament, and in¬ vests the proper nervous substance. It must not, how¬ ever, be imagined that the neurilema forms a cylindrical tube, in the interior of which the nervous matter is con¬ tained. This latter disposition, if it actually exists, ap¬ plies to the smaller nerves only, and to some of those which go to the organs of sensation,—a peculiarity which we shall notice subsequently. Any large nervous trunk, for example the spiral or median of the arm, or the sciatic nerve of the thigh, is found to be composed of several small nervous chords placed in juxtaposition, and each of which, consisting of appropriate neurilema and nervous substance, is connected to the other by delicate filamentous tissue. These, how¬ ever, do not through their entire course maintain the parallel disposition in respect to each other, but are ob¬ served to cross and penetrate each other, so as to form an intimate interlacement of nervous chords and fila¬ ments, each of which, however minute, is accompanied with its investing neurilema. The neurilema, in short, may be represented as a cylindrical membranous tube, giving from its inner surface many productions forming smaller tubes (canaliculi ; die Nervenrohre ; primitive cy¬ linders of Fontana2), in which the proper nervous matter is contained. Of this arrangement the consequence is, that each nerve or nervous trunk, enveloped in its general neurilema, is composed, nevertheless, of a number, more or less con¬ siderable, of smaller chord-like nervous threads {funiculi nervei, Prochaska; chordce, fanes, Nervenstrdnge, Reil), into which the nerve, by maceration and suitable prepa¬ ration, may be resolved. Each chord, again, or nerve¬ string, as Reil terms it, though invested with a proper neurilem, may be further resolved into an infinite number of minute filiform or capillary filaments {Jila, Jibrillce, Nervenfasern, Reil), which, invested in a delicate cover¬ ing, are understood to constitute the ultimate texture of the nerve. This threefold division may be easily observed in the Get d brachial and spiral nerves of the arm, and still more dis- Anat.iy. tinctly in the sciatic in the thigh. The utility of under- standing the internal arrangement from which it results ^er *• will appear forthwith, when the structure of those parts termed ganglions and plexuses comes under examination. Of this arrangement in different nerves, and in different regions, this membrane undergoes great modification ; and all opinions on its nature derived from thickness or trans¬ parency are liable to considerable fallacy. Scarpa seems to view it as connected, in anatomical origin and charac¬ ter, with the hard membrane {meninx dura, dura mater). Reil, who devoted more care and time to the examination of its nature and structure than any other inquirer, repre¬ sents it as consisting of cellular substance, many blood¬ vessels, and some lymphatics.3 Bichat thinks it re¬ sembles the soft membrane of the brain {pia meninx, pia mater), and is derived from it.4 Gordon considers the neurilema of the cerebral nerves as consisting of soft mem¬ brane {pia mater) at their origin, but in all other situations as a species of cellular membrane. By Mayer the neurilema is accounted a fibrous tissue, for the following reasons. Is?, It consists almost entirely of tendinous fibres, and is cellular only where it is very thin. 2c?, The transverse folds presented by most of the nerves, and which give them a denticulated form, are de¬ rived from the neurilema, are of fibrous character, and are similar to those observed in tendinous sheaths. 3c?, Seve¬ ral nervous productions are actually converted into tern dinous or fibrous filaments ; for example, the brain of the snail tribe, and the spinal chord both in these and other animals at the cauda equina. 4?A, The neurilema is either a continuation of the proper cerebral membrane {pia mater), or very similar to it; and this membrane is fibrous and aponeurotic at the spinal chord, and even at its upper end, and, according to Mayer, forms the denticulated ligament, which is a fibrous tissue. These views, which are the result, not of observation, but of hypothesis, it is impossible to adopt. Its connection with the pia mater was disproved by Reil; and though its analogy with the denticulated ligament were established, it would prove nothing regarding the neurilema. Upon the whole, the idea of Reil is the most probable. Accord¬ ing to the observations of this anatomist, who examined the neurilema after fine and successful injection, it is libe¬ rally supplied with blood-vessels. These proceeding from the neighbouring arteries penetrate the filamentous sheath of the nerve ; and, immediately on reaching the neurilema, divaricating at right angles, generally run along the nerv¬ ous threads {funes), parallel to them, forming numerous anastomotic communications, and divide into innumerable minute vessels, which penetrate between them into the minute neurilematic canals. So manifold is the ramifica¬ tion, and so minute the distribution, that in these canals not a particle of nervous substance is found which is not supplied with a vessel.5 The arrangement of the veins is analogous. . , It appears, therefore, that the neurilema is a tissue of membranous form, with a multiplied mechanical surface, liberally supplied with blood-vessels, from which the nervous matter is secreted and nourished. It is impos¬ sible, indeed, to doubt that, of the two parts which com¬ pose the nervous chord, it is the most perfectly organiz- 1 The term dynamic is used to denote in a general sense the properties of animal substances. 2 Observations sur la Structure des Nerfs, &c. apud Traite. stir le Vcntn, &c. par M.

G ?ral ed ; and that, though it may not be similar in structure to An my. the pia mater, it is (juite analogous in the use to which it ^/."^is subservient. Like that membrane, it sustains the N«*• vessels of the nerve ; it presents a multiplied surface, over which the vessels are distributed; and, by penetrating deep into the body of the nerve, it conveys the nutritious vessels in the most capillary form to the inmost recesses of the nervous substance.1 The arrangement which has been above described is the only one which can be regarded as general. It varies in particular regions; and these varieties in the neurile- matic disposition occur principally in the nerves which are distributed to the proper organs of sensation.2 ls£, The olfactory nerve is soft, pulpy, and destitute of neurilema, from its origin in the Sylvian fissure, to the gray bulbous enlargement which terminates its passage in the cranium ; but as soon as it reaches the canaliculi or grooves of the ethmoid bone, and begins to be distributed through the nasal anfractuosities, it is distinctly neurilematic. 2d, The optic nerve is still more peculiar in this respect. The instant it quits the optic commissure (commissura trac- tuum), it begins to be invested by a firm general neurile¬ ma, which sends into the interior substance of the nerve various membranous septa or partitions, forming separate canals, in which the nervous matter is contained. These partitions, however, are so thin, that at first sight the optic nerve seems to consist merely of one exterior membranous cylinder inclosing the proper membranous substance. 3d, Lastly, we may remark, that the auditory nerve, or the soft portion of the seventh pair of most anatomical writers, is the only nerve in which this covering cannot be traced. The neurilema is much thinner and more delicate in the nerves which are distributed to the internal organs, as the lungs, heart, stomach, &c. (nerves of the organic life, great sympathetic and pneumogastric nerves, par vagum), than in those belonging to the muscular system. The second component part of the nervous chord or filament is the proper nervous matter which occupies the cavity of the neurilematic canals. Little is known con¬ cerning the nature or organization of this substance. It is whitish, somewhat soft, and pulpy; but whether it con¬ sists of aggregated globules, as was attempted to be esta¬ blished by Della Torre and Sir Everard Home, or of linear tracts disposed in a situation parallel to each other, as appears to be the result of the inquiries of Monro, Reil, and others, or of capillary cylinders containing a transpa¬ rent gelatinous fluid, as Fontana represents, seems quite uncertain. It has been presumed, rather than demonstrat¬ ed, that it resembles cerebral substance. But this analo¬ gy, though admitted, would throw little light on the sub¬ ject ; for at present it is almost impossible to find two anatomical observers who have the same views of the in¬ timate nature of cerebral substance itself. Whatever be its intimate arrangement, it appears to be a secretion from the neurilematic vessels. (Reil.) The structure of the nervous chord may be demon¬ strated in the following manner. When a portion of nerve is placed in an alkaline solution, the whole, or near¬ ly the whole, of the nervous matter is softened and dis¬ solved, or may be washed out of the neurilematic canals, 733 which are not affected by this agent, and the disposition General of which may be then examined and demonstrated.3 Anatomy. Aqueous maceration may likewise be advantageously em- ployed to unfold this structure; for it separates and de- Nerves* composes the cellular tissue by which the neurilematic canals are united, and subsequently occasions decomposi¬ tion of the nervous substance, while it leaves, at least for some time, the neurilema not much affected. When, however, the maceration is too long continued, it is se¬ parated and detached like other macerated textures. Lastly, If a large nerve be placed in diluted acid for the space of one or two weeks, the neurilema is gradu¬ ally dissolved, and the nervous matter becomes so much indurated and consolidated that it may be separated from the contiguous chords in filaments with great facility.4 In undergoing this change, the portion of nerve becomes much shorter and considerably contracted,—is subjected, in short, to the process of crispation ; so that unless a large nerve like the sciatic be employed for the experi¬ ment, it may be impossible to obtain the result in the most satisfactory form. These experiments, with many others of the same nature, were first performed by Pro¬ fessor Reil, and afterwards repeated and varied by Bichat and Gordon. Personal repetition of them enables me to assert, that, when correctly conducted, they never failed to give the results as described by these authors. Nervous tissue, like all others, receives a proportion of what may be denominated the systems of distribution,— cellular tissue and blood-vessels. In the substance of the former, the disposition of which we have already remark¬ ed, we find the more conspicuous branches of the latter distributed. In a more minute and divided form they penetrate the neurilema and nervous substance. Reil, who derived his conclusions from the result of delicate and successful injections, perhaps over-rated the quantity of blood which in the sound state they convey; for it is quite certain that, in the healthy state, hardly any red blood enters the nervous tissue, as may be easily shown by exposing the sciatic nerve of a dog or rabbit. No good chemical analysis of nervous matter has yet been published. Every chemical examination of it has been conducted on the assumption that it is analogous to cerebral matter. Of this, however, there is no direct proof. In the analysis by Vauquelin, the neurilematic co¬ vering appears not to have been detached,—a proceeding always necessary to obtain correct results in this inquiry. The effects of acids and alcohol show that it contains al¬ buminous matter ; but beyond this it is impossible at pre¬ sent to make any precise statements. This description may communicate an idea of the struc¬ ture of the nervous chord in general. In particular situ¬ ations this structure is considerably modified. The modi¬ fications to which we allude occur under two forms—gang¬ lions (die Knoten), and plexuses (die Nervengeflechte). Every ganglion consists essentially ot three parts,—1^, Nervous an exterior covering; 2d, a collection of minute nervousgangfi°ns’ filament; and, 3d, a quantity of peculiar cellular or fila¬ mentous texture, by which these filaments are connected, and which constitutes the great mass of the ganglion. The ganglions are of two kinds, the spinal or simple, and the non-spinal or compound. Ihese two kinds of Iteil, Exercitationes Anatomicce de Structura Nervorum, cap. i. 2 By the term “ proper organs of sensation” are understood those of sight, hearing, smell, and taste, which are confined to a fixed spot in the system. 3 Iteil de Structura Nervorum, cap. i. p. 3 and 5. . . 4 According to the experiments of Reil, nitrous acid diluted with water answers best. Muriatic acid, though equal or even supe¬ rior in effecting solution of the neurilema, softens the nervous matter too much, and separates the component filaments too com¬ pletely. (De Structura Nervorum, cap. iii. p. 16.) 734 ANATOMY. General bodies differ from each other,—Ltf, in the situation which Anatomy, they respectively occupy; 2c?, in the kind of envelope with which they are invested; 3d, in the mode in which the N™s nervous filaments pass through them and from them. By ganft ions, w}10 considers the ganglion of Gasserius, the cili¬ ary and the maxillary of Meckel, as cerebral ganglions, they are divided into three sets, those of the cerebral sys¬ tem, the spinal system, and the vegetative, or those con¬ nected with the organs of involuntary motion.1 Void of the dense strong coat with which the others are invested, the cerebral ganglions consist of soft second¬ ary matter, connected to the filaments of one, or at most two branches, and are arranged with less complexity. (Wutzer.) The spinal ganglions are said to possess two coverings, one of which resembles the hard -cerebral membrane (meninx dura), the other the soft cerebral membrane (meninx tenuis, pia mater). The non-spinal or compound ganglions have also two coverings, which are merely dif¬ ferent modifications of filamentous tissue, less dense and compact than in the former. Both these sets of ganglions being by maceration stripped of their tunics, and depriv¬ ed of the soft, pulpy, cellular matter, are resolved into an innumerable series of nervous threads, most of which are minute and scarcely perceptible : all are continuous with the nerve or nerves above and below the ganglion. It appears that the nervous chord, when it enters the one apex of the ganglion, begins to be separated into its com¬ ponent threads, which diverge and form intervals, between which the delicate cellular tissue is interposed; and that these filaments are subsequently collected at the opposite extremity of the ganglion, where they are connected with the other nerve or nerves. Scarpa, to whom we are in¬ debted for most of the knowledge we possess on this sub¬ ject,2 compares the arrangement to a rope, the component cords of which are untwisted and teased out at a certain part. Lastly, In the simple ganglions, the filaments of which they consist invariably follow the axis of the gang¬ lion ; but in the compound ones they are found to rise towards the sides and emerge from them; and upon this variety in the direction and course of these filaments de¬ pends the variety of figure for which these two orders of ganglions are remarkable. These nervous threads (sta- mina s. fila nerved), described by Scarpa, correspond to the medullary filaments {fila medullaria) of Wutzer. Ac¬ cording to this anatomist, these filaments, when about to enter the ganglion, lay aside their neurilem ; yet they are sufficiently tough to resist a certain degree of tension. Wutzer mentions a cluster of vesicles or cells {cancelli) in the filamentous tissue of the ganglion ; but he was not enabled by any means, mechanical or chemical, to ascer¬ tain their exact nature. The ganglions are well supplied with blood-vessels, de¬ rived in general from the neighbouring arteries. The in¬ timate distribution is represented by Wutzer to be the following. The artery proceeding to a ganglion gives vessels to the filamentous tissue, and, perforating the pro¬ per coat, is immediately ramified into innumerable minute canals, the first order of which forms vascular nets on the inner surface of the tunic, while the residual twigs pene¬ trate the flocculent texture, and the individual vesicles of the secondary or filamentous matter of the ganglion.3 This short exposition of the structure of the ganglions shows the mistaken notions of Johnstone, Unzer, Bichat, and others, on the structure and uses of these bodies. Gefa] ls£, The idea, first advanced by Johnstone and Unzer, Ansjn adopted by Metzger, Hufeland, Prochaska, Sue, and^K Harless, and afterwards applied with so much ingenuity ,Us by Bichat, that the ganglions are so many n-ervous cen-gan: ns’' tres or minute brains, is disproved by strict anatomical observation. 2c?, That they are connected with the order of involuntary actions, and influence these actions, is a gratuitous hypothesis, and may be true or false without being necessarily the case. 3c?, Lastly, we remark, as a circumstance of some importance, that the only difference between a ganglion and any other part of a nervous chord is, that in the former the minute nervous filaments appear to be uncovered with neurilema, and lodged in a mass of cellular tissue, which is inclosed in the neurilematic capsule; while in the latter each nervous filament has its appropriate neurilema, and the cellular tissue, instead of being within, is on its exterior, and connects it to the contiguous filaments. In various situations two, three, or more nervous trunksNer or chords mutually unite by means of some of their com-pkx ponent threads, and after proceeding in this manner for a short space, again separate, but not in the same number of original trunks, or preserving the same appearance. In general, the number of chords into which they finally separate is greater than that of which they consisted be¬ fore union. Three or four nervous trunks, for example, after uniting in this manner, will form on their final sepa¬ ration five or six nerves or nervous chords; and it is quite impossible to determine which of the latter order was derived from any one or two of the former, or what number of individual chords it has received from each. Between the two points, also, the first point of union and the last of separation, many of the more component threads are detached from two or more of their trunks, and, after first uniting with each other in an indistinct net-work, are again united to two or more of the nervous chords near the point at which they finally separate from the further end of union. This arrangement has been termed a plexus, plait, or weaving, in consequence of the manner in which the nervous chords are interlaced or plaited toge¬ ther. The arrangement which we have noticed as con¬ sisting of the more minute nervous threads has been call¬ ed a smaller plexus {plexus minor). It is a subordinate plexus within a larger one. The best and most distinct example of a plexus is that commonly named the brachial or axillary. This, as is well known, is situate in the space contained between the broad dorsal muscle {latissimus dorsi) behind, and the great pectoral muscle before, and is formed in the follow¬ ing manner. The fifth, sixth, seventh, and eighth cervi¬ cal nerves, and the first dorsal, after forming the usual connections {ansae), pass downwards from the vicinity of the vertebrae between the middle and anterior scaleni muscles, and, nearly opposite the lower margin of the seventh cervical vertebra, or about the level of the first rib, begin to be united by the component threads of each nerve. Threads of the fifth and sixth cervical unite, sometimes to form a single chord, in other instances to be connected a short space onward with threads of the seventh cervical in a similar manner. The seventh and eighth form two kinds of union. When the seventh is large, it divides almost equally into two chords or branches, one of which is connected first with the fifth and sixth, 1 Dc Corporis Humani Gangliorum Fabrica, See. cap. i. ii. sect. 41, p. 52. 2 Anatomicarum Annotationum liber primus dc Nervorum Gangliis et Plexibus.

ANATOMY. ^#1 afterwards with the eighth, and with the first dorsal by iiiatjiy- interlacement of minute nervous threads. The other either passes downward to form one of the separate bra- Mus chial nerves, or is also connected with the eighth cervical and first dorsal in a plexiform manner. From this arrangement immediately arise the individual nervous branches which form the nerves of the arm, and which are named brachial nerves. The interlacement of minute nervous threads between the seventh and eighth cervical and the first dorsal, is what Scarpa has termed the plexus minor. He says it is peculiar, in being quite uniform, and in connecting those nervous branches which, from their subsequent destination, are called median and ulnar. This description, though not generally applicable, will communicate some faint idea of the nervous unions and interlacements termed plexus or webs. For more minute information on the distribution, arrangement, and confi¬ guration of this part of the nervous system, we refer to the work of Scarpa already quoted.1 Plexiform arrangements are not confined to the exte¬ rior regions of the body. They are more numerous inter¬ nally; and almost all the organs of the chest and belly have each a plexus, sometimes two, from which they de¬ rive their nervous chords. Plexiform arrangements are generally situate in the neighbourhood of blood-vessels, and in some instances in¬ closing considerable arterial trunks more or less accurate¬ ly. Thus the axillary plexus surrounds the axillary ar¬ tery. The cceliac artery is surrounded with the solar plexus; and the coronary, hepatic, splenic, superior me¬ senteric, and renal, are also surrounded with plexiform nervous filaments. In some instances these nervous fila¬ ments are so intimately connected with the arterial tubes as to lead some anatomists to consider them as forming a peculiar net-work surrounding the vessel, and to exercise great influence on the circulation. (Wrisberg, Ludwig, and Haase.) It is remarkable that the structure of the nervous chords which form a plexus has either appeared so simple as not to demand particular attention, or is so obscure as to be never noticed. Have the nervous chords and threads in such situations their usual envelope ? Is the nervous matter in the chords quite the same as in other situations ? Are there any other means of union, save the nervous sub¬ stance itself? We believe there is no doubt that every chord in a plexus is provided with its neurilema, as in other places ; but this neurilema is generally thinner and more delicate, and the general neurilema seems to be wanting. Its mechanical properties of cohesion and re¬ sistance have not been examined. The view now given of the structure and arrangement of the nervous plexus leads Scarpa to consider them as nearly allied to ganglions. The same separation of the component threads or filaments of the nerve or nerves, the same interlacement, and the same or similar formation of new chords, appear to take place in both orders of structure. A ganglion, indeed, he conceives, is a con¬ densed or contracted plexus; and a plexus is an expand¬ ed or unfolded ganglion. The anatomical purpose of both appears to be simply a new arrangement or disposition of ^ervous branches, previous to their ultimate distribution |n the tissues or organs to which they are destined. This is nothing but the expression of a fact,—the interpreta¬ tion in intelligible terms of an arrangement of organized parts, without reference to any supposed uses. 735 I have already shown what is meant by the organic General end or termination of a nerve. Although the nervous Anatomy, trunks are distributed in every direction through the ani-'^^^' mal body, they do not terminate in all the tissues or or- ^erve3- gans indiscriminately, and have been observed to be lost in the following only: 1st, The proper organs of sensa¬ tion, the eye, ear, nose, palate, and tongue; 2dly, the muscles, whether subservient to voluntary or to involun¬ tary motion, as the heart, stomach, intestines, &c.; Sdly, the mucous surfaces; kthly, the skin; 5thly, glands, sa¬ livary, liver, kidneys, &c.; Sthly, bones. _ Nerves, therefore, are not organs of general distribu¬ tion. According to Bichat, they have never been traced to the following tissues:—the cartilages, both articular and of the cavities; fibrous textures, \\z. periosteum, dura meninx, capsular ligaments, aponeurotic sheaths, aponeu¬ rosis in general, tendon, and ligament; fibro-cartilaginous textures—those of the external ear, nose, trachea, and eyelids (cartilages of other authors) ; the semilunar carti¬ lages of the knee-joint; those of the temporo-maxillary articulation ; those of the intervertebral spaces ; marrow; the lymphatic glands. To this we may add the testimony of Walter of Berlin, who, after several laborious researches, came to the con¬ clusion that the pleura, the pericardium, the thoracic duct, and the peritoneum, receive no nerves, and that, contrary to the opinions of the most eminent recent ana¬ tomists, no nerves terminate in the lymphatic or conglo¬ bate glands. Sometimes, indeed, these organs are perfo¬ rated by one or two twigs, as he often had occasion to observe; but they instantly proceed to the next place as¬ signed to them, and in which they are finally lost.2 If, after this conclusion of Walter, personal testimony can ba of any use, I may add, that I have examined the dura mater, the periosteum, and most of the synovial mem¬ branes repeatedly, to discover nervous filaments in them, and always without success; and I may say the same re¬ garding the absence or non-appearance of nerves in the peritoneum and pleura. The nerves have different uses in the different organs and tissues to which they are distributed. 1. In the or¬ gans of sensation they receive the material impressions made on the mechanical part of the organ. In the mu¬ cous membrane of the nasal passages, the filaments of the olfactory nerve are affected by aromatic particles, dis¬ solved or suspended in the air. In the eye the retina re¬ ceives the last image formed by the transmitting powers of the transparent parts. In the ear the terminations of the auditory nerve are affected by the oscillations or minute changes in the fluid of the labyrinth, occasioned by the motions of the tympanal bones. In the palate, tongue, and throat, the gustatory nerves are affected by sapid bodies dissolved in the mouth, or applied in a fluid state to the mucous membrane of that cavity. 2. In the system of voluntary muscles, the nerves retain the action of the muscular fibres in a state of uniformity and equality; and keep them obedient to the will. In the involuntary muscles they appear merely to keep their action equable, regular, and uniform; and in both they maintain a com¬ munication, consent, or harmony of action between dif¬ ferent parts of the same system of organs, or even between organs concurring to the same function. 3. In the glan¬ dular organs the nerves certainly exercise some influence over the process of secretion; but what is the exact na¬ ture of this influence, or in what degree it takes place, is quite uncertain. This may be said to comprehend all that 1 Annotation. Anatom, cap. iii. sect. 9, p- 94, 95. * PrceJ'at. Tab. Nero. Thoracis et Abdominis, J. G. Walter. Berolini, 1783. 736 ANATOMY. General is accurately known regarding the uses of the nerves. Anatomy. Every other doctrine relating to sensibility, sympathy, ir- ritability, &c. is either unfounded, not proved, or altoge- erves. i1Tiaginary and hypothetical. In the foetus the nerves are developed with remarkable perfection. I cannot speak from personal observation much earlier than the sixth month, when I have found the nerves of the extremities and voluntary muscles large and distinct. At the eighth month they are still more conspicuous. The anterior crural nerves are in the form of flat white cords, one and a half line broad, and their branches like good-sized threads. The sciatic is still more distinct. In the form of a thick cylindrical cord, fully a line in diameter, and not unlike a piece of whip¬ cord, it is tough, stringy, and resists tension ; and its con¬ stituent threads are well marked. I immersed a portion of this nerve three and a half inches long in aquapotassa, when it first became much firmer and denser than before, assumed in two days the satin fibrous appearance first described by Fontana, and at length by solution of the nervous matter was separated into chords and neurilema- tic canals. In this state, preserved in spirit of turpentine, it conveys a tolerably correct idea of the arrangement of the neurilematic canals. The nerves of the involuntary muscles are equally dis¬ tinct in proportion. Those of the lung, heart, and splanch¬ nic system are distinct and manifest at the eighth month. The neurilem is much more vascular in the foetus than in the adult. In the same foetus of about eight months I found the neurilem of the sciatic nerve, from the ischiatic notch to its divarication in the ham, covered with a thick net-work of minute vessels, all injected with dark blood. CHAP. II. THE PARTICULAR TISSUES. Cerebral Substance,—Brain. ( Cerebrum.) Brain. The brain or central part of the nervous system may be regarded as a continuous organ, consisting of three divi¬ sions,—the convoluted, the laminated, and the smooth or funicular portions. Of these divisions, which are distin¬ guished according to the peculiar external configuration of each, the first part corresponds to what is named the brain proper {cerebrum); the second to the small brain {cerebellum) ; and the third to the oblong production con¬ tained in the vertebral column, and known under the name of the spinal chord. The convoluted portion presents two surfaces, an outer or convoluted, and an inner or figurate. The laminated portion in like manner presents two surfaces, an outer or laminated, and an inner or central. The third has only one surface, which is exterior. These different surfaces, and their mutual relations, will be more minutely explain¬ ed afterwards. At present we shall examine its physical and anatomical characters as an organic substance. ’ The three divisions of the central part of the nervous system are composed of a peculiar substance, which may be denominated cerebral matter, inclosed in delicate vascular membranes. To exhibit the external characters of this substance, these membranes must be removed by careful dissection. When this is done, and the brain is inspected on its surface, and after sections, the cerebral matter is observed to vary in colour, consistence, and intimate structure in different parts of the organ. These varieties of cerebral matter are most easily distinguished, according to their colour, into white and gray or cinereous. The white cerebral matter is of different shades in dif¬ ferent parts of the brain. Its most usual hue is orange- white, or orange-wdnte inclining to reddish white, or pur- if n. ral plish white. This is most distinctly recognised in the G< mesolobe {corpus callosum), and in the body named hippo- An ny campus major. The consistence of the white cerebral matter is considerable. It is in general more tenacious T and cohesive than the gray matter, and when indurated is less brittle. A section made by a sharp scalpel appears smooth and of a uniform colour, traversed by reddish points and streaks. It presents nevertheless different appearances in different directions. In certain parts, for example the mesolobe, it presents the appearance of minute capillary lines, arranged in parallel juxtaposition, and giving what is named a fibrous appearance. In other regions, however, as in the white matter of the optic chambers, this cannot be recognised. White cerebral matter has been examined microscopi¬ cally by Della Torre, Prochaska, the Wenzels, Sir Everard Home, and M. Bauer. If we trust the observations of Father Della Torre, the white and gray substance of the brain, cerebellum, medulla oblongata, and spinal chord, consist of an aggregation of infinite transparent globules, floating in a pellucid, crys¬ talline and somewhat viscid fluid. The only difference which he admits among the matter of these several parts is, that he represents the globules to be largest in the brain, smaller in the cerebellum, and still more minute in the medulla oblongata and spinal chord. The arrangement of these globules in the central portion of the nervous system he further represents to be promiscuous. Prochaska placed on a thin plate of glass minute slices of cerebral matter, so thin that they were translucent; and in this state he found it consist of innumerable globular particles, united by delicate, pellucid, flocculent matter, like filamentous tissue. These globules varied in size even in the same part of the brain. In general, how¬ ever, he found them both in the brain and cerebellum to be rather more than eight times smaller than the globules of the blood. He was unable to ascertain any thing re¬ garding their intimate structure. The Wenzels found the white cerebral matter to consist of very minute globules, or roundish atoms, resembling spherical cells containing proper medullary or white cere¬ bral substance. The dimensions of these globules they did not attempt to estimate; but represent them in gene¬ ral as exceedingly minute, and all of the same size. They could not recognise any connecting medium. The globu¬ lar appearance was retained in portions of brain exposed to the action of alcohol and muriatic acid, and in those even which had been dried after induration in alcohol. M. Bauer placed a thin slice of white cerebral matter on a plate of glass previously moistened, and allowing a drop of water to fall on it, held obliquely, and thereby to dimi¬ nish its cohesion, brought into distinct view innumerable loose globules, many fragments of fibres of single rows of globules, and bundles of fibres, some of considerable length. The use of the water in this mode of examination is to dissolve and removeaviscid, gelatinous, semifluid substance, on which the adhesive properties of the white matter seem to depend. If the water is not used, the brain adheres to the glass, and the globular appearance cannot be recog¬ nised. These globules vary in size from t0 TGWU an inch in diameter ; the general or average size being Those of the white matter are largest, that is ^Too" are translucent, whitish, and arranged in lines or rows of single globules, which are attached to each other by the vis¬ cid semifluid mucus. The strings or rows of globules are connected into bundles or fasciculi by the same medium. ANATOM Y. 737 Ga.al There is reason to believe that the translucency of the U«ny< globules depends on an albuminous fluid, which on immer- sion in alcohol or acids is coagulated, and thereby render- ed opaque. When a portion of white cerebral matter is immersed in boiling oil, or is steeped for a few days in alcohol, di¬ lute nitric or muriatic acid, or in a solution of corrosive sublimate, it acquires great firmness and solidity, and may be torn or broken like a piece of cheese, which it could not be before, in consequence of its tenacity. Cer¬ tain parts, for example the mesolobe, appear then to be distinctly fibrous, or to consist of long capillary lines placed in close juxtaposition. On the length of these filaments or fibrils, however, nothing is ascertained. It is also undetermined whether the white cerebral matter is in all parts arranged in the fibrous manner. White cerebral matter is well supplied with blood¬ vessels. These, indeed, are minute; but they consist both of vessels containing red and colourless blood. The di¬ vision of these vessels gives rise to the appearance of red points (jpunctula) and streaks, which are exhibited on the surface of sections. It is believed to be less vascular than file gray cerebral matter. On the chemical constitution of white cerebral matter we possess no accurate information ; all the chemical analyses hitherto made having been directed to brain, without distinction of its different varieties. From the circumstance, however, of its becoming indurated on im¬ mersion in alcohol, acids, and solutions of corrosive subli¬ mate, it is manifest that it contains much albumen. It is rendered yellow by nitric acid. If a portion of indurated brain be placed in the sun, or in a warm atmosphere, an oily or unctuous fluid exudes from its surface, which shows that it contains fatty matter; and if brain be im¬ mersed in ether, this fatty matter is partially removed. From the analysis of Vauquelin, it may be inferred that the white cerebral matter contains the 4-43 per cent, of white adipose substance found by that chemist in his ana¬ lysis. It is also believed to contain phosphorus. The gray or cinereous cerebral matter, though variable in colour like the white, is in general a mixture of ash- gray and wood-brown, darker than the former, but lighter than the latter. The colour varies at different ages. It is light in early life, and deeper as life advances. The gray cerebral matter is softer and less viscid and tenacious than white cerebral matter. It is distinctly granular, both in the external surface and when torn or broken. This appearance, however, is most distinctly recognised after induration in alcohol or acidulous li¬ quors. In the convoluted part of the brain, where it is most abundant, it does not present the fibrous or parallel linear arrangement, and is merely an aggregated mass of numerous minute granules. It is uncertain whether it presents the fibrous arrangement in other parts of the brain. An appearance of this kind is recognised in the unciform bundle at the inner end of the fissure of Syl¬ vius, and also in the streaked bodies and the annular protuberance. But the appearance alluded to seems to depend not on the genuine fibrous arrangement of the granules of the gray matter, but merely on the gray Matter being deposited in streaks and lines between the white. Meckel nevertheless maintains that the gray matter is also fibrous. According to the observations of Sir Everard Home and M. Bauer, the gray cerebral matter consists of minute globular atoms, smaller than those of the wdiite matter, or varying from to of an inch in diameter. Fhese globules appear to be united, though more loosely, hy a sero-albuminous fluid of a yellower tint than that of Vol. II. the white matter. Home supposes this albuminous fluid General to be less abundant in the gray matter. Anatomy. Gray cerebral matter is well supplied with blood-ves- sels, which are large and numerous. It must not be •Braia* imagined, however, that all the vessels which are observ¬ ed to enter this substance are therefore distributed to it. These large vessels necessarily penetrate the gray matter of the convoluted surface before they reach the white matter in the centre; and though they send branches to the former, they are ultimately distributed to the latter. The gray cerebral matter has been supposed to be more vascular than the white ; but the circumstance now stat¬ ed renders this doubtful. The statement of Sir Everard Home, that “ the finest and most delicate branches of the arteries and veins are only found in the cortical, i. e. the gray substance,” is contradicted by observation; for the vessels are certainly in general larger and more dis¬ tinct in this than in the white matter. But if they are larger in the former, they are more numerous in the latter. On the whole, perhaps, there is little difference between the vascularity of the white and gray substance of the brain. The chemical constitution of gray cerebral substance has not been accurately examined. The results of ana¬ lysis show, nevertheless, that it contains albuminous matter to the amount of about 7 per cent., with O70 of a peculiar red adipose matter, which is probably the cause of the peculiar colour. These two varieties of cerebral matter are combined in various modes and proportions in the brain. In general the gray matter is found on the exterior, for instance on the convoluted surface of the brain, and on the laminated surface of the cerebellum ; while the white matter is ar¬ ranged in the central parts. Gray matter, nevertheless, is found in the interior, in the streaked bodies and optic thalamus, and in the moriform bodies (corpora dentata) of the cerebellum and olivary eminences. Besides the two varieties of substances now mention¬ ed, a third, of a deeper shade, is found in the brain. Thus, in the centre of the cerebral limbs is a quantity of cere¬ bral matter of a dark or ink-spotted tint, which Vicq d’Azyr therefore named the black spot (locus niger) of the limbs of the brain. The nature of this black spot, which is quite uniform, is entirely unknown. It appears merely to be a modification of the gray matter. A yellow-coloured substance has also been supposed to exist in the centrum semicirculare geminum, a narrow band between the striated body and optic thalamus. This sub¬ stance is certainly firmer than the adjoining white and gray matter, and it is further peculiar in possessing a sort of tint between wax-yellow and wine-yellow. It is highly vascular. Of its other peculiarities, however, we know nothing; and we must be satisfied with regarding it as an anomalous species of animal substance, approaching to gray cere¬ bral matter in colour, but infinitely firmer and more te¬ nacious. The parts named pituitary and pineal glands present several peculiarities deserving attention; but these more properly come under the head of Special than of General Anatomy. Flesh, Muscle. (Mug,—Muss,—Musculus,—Lacertus,— Tori?) Muscular Tissue. (Tissu Musculaire.) The ordinary appearance of the substance named flesh Muscle, or muscle is familiar; and it is unnecessary to enumerate those obvious characters which are easily recognised by the most careless observer. A portion of muscle, when carefully examined, is found to consist of several ani- 5 A 738 ANATOM Y. Muscle. General mal substances. It is traversed by arteries and veins of Anatomy, various size; nervous twigs are observed to pass into it; it is often covered by dense whitish membranous folds (fasciae), or by serous or mucous membranes, all which shall be examined afterwards; and it is found to contain a large proportion of filamentous tissue. But it is distin¬ guished by consisting of numei’ous fibres disposed pa¬ rallel to each other, and which may be separated in the same manner by proper means. The appearance, arrange¬ ment, and characters of these fibres demand particular notice. According to Prochaska, muscle in all parts of the body may be resolved, by careful dissection, into fibres of great delicacy, as minute as silk filaments, but pretty uniform in shape, general appearance, and dimensions. Their dia¬ meter appears not to exceed the 40^00 Par^ an whatever be their length. They seem all more or less flattened or angular, and appear to be solid diaphanous filaments. Prochaska, not doubting that these muscular threads (JHa earned) are incapable of further division, terms them primary muscular fibres. The microscopical examination of the atomic constitu¬ tion of the muscular filament, which was first attempted by Leeuwenhoeck, and afterwards prosecuted by Della Torre, Fontana, Monro, and Prochaska, has been recently reviv¬ ed by M. Bauer, the indefatigable assistant of Sir E. Home. From the observations of this accurate inquirer, each muscular filament appears to consist of a series of globular or oblong spheroidal atoms, disposed in a linear direction, and connected by a transparent, elastic, jelly-like matter. (Phil. Trans. 1818, 1826.) The primary muscular fibres are placed close and pa¬ rallel to each other, and are united in every species of muscle into bundles (fasciculi, lacerti) of different but determinate size; and according as these bundles are large or small, the appearance of the muscle is coarse or delicate. In the deltoid the bundles are the largest. In the vasti, glutcei, and large pectoral muscles the bundles are greatly larger than in the psoce. In the muscles of the face, of the ball of the eye, of the hyoid bone, and especially in those of the perineum, these bundles are very minute, and almost incapable of being distinguished. The number of ultimate filaments which compose a bundle varies in different muscles, and probably in different ani¬ mals. In a muscular fibre of moderate size in the human subject, Prochaska estimates them to vary from 100 to 200; and, in animals with larger fibres, at double, triple, or even four times that number. There is reason to con¬ clude, from correct microscopic observation, that the largest do not exceed the ^ of an inch, and that the small¬ est are not less than ^ By cutting a muscle across, these bundles are observed to differ, not only in size, but in shape. Some are oblong and rhomboidal, others present a triangular or quadran¬ gular section, and in some even the irregular pentagon or polygon may be recognised. These bundles are united by filamentous tissue of vari¬ ous degrees of delicacy, as may be shown by the effects of boiling; and the muscle thus formed is penetrated by ar¬ teries, veins, and nervous twigs, and is inclosed by fila¬ mentous tissue, which often contains fat. This fascicular arrangement appears to be confined to the muscles of voluntary motion. It is not very distinct in the heart or diaphragm; and in the urinary bladder and intestinal canal it is not recognised. Nor is the pa¬ rallel arrangement of the ultimate filaments always strict¬ ly observed in the involuntary muscles. The component fibres of this order of muscles are often observed to change direction, and unite at angles with each other. This fact, which was observed by Leeuwenhoeck, has been verified by Ge w Prochaska. The colour of muscle varies. In man and the mammiA ferous animals, at least adult, it is more or less red; in many birds and fishes it is known to be whitish; in young animals it is grayish or cream-coloured ; and the slender fibres which form the middle coat of the intestines in all animals are almost colourless. The colour of the muscles of voluntary motion in man is red or fawn ; but repeated washing or maceration in alcohol or alkaline fluids renders them much paler. The examination of the physical properties of muscle has occupied the industry of Muschenbroek, Croone, Browne Langrish, Wintringham, and others of the iatro- mathematical school. I cannot perceive that minute knowledge of these properties is of much moment to the elucidation either of its sound or its morbid states. Amidst the variable results obtained in such an inquiry, the only certain point is, that muscular fibre has less tenacity and mutual aggregation than most other tissues. It sustains much less weight and force of tension without giving way. Chemical analysis has not yet furnished any satisfac¬ tory results on the nature of muscular tissue ; but the gene¬ ral results of the numerous experiments already instituted show that muscle contains fibrin, albumen, gelatine, ex¬ tractive matter (osmazome), and saline substances. It is difficult to say how far the gelatine is to be regarded as proper to muscle, or derived from the filamentous tissue in which it certainly exists. The saline matters are com¬ mon to muscle with most other organic substances. There is reason to believe that fibrin in considerable quantity, and albumen and osmazome in smaller proportion, are the proper proximate principles of muscle. Though the vari¬ ous proportions of these principles have been stated in numbers by chemists, it is impossible in the present con¬ dition of animal chemistry to place any reliance on them. It is also to be remembered that the relative proportion of the proximate principles varies at different periods of life. In early life the muscular fibre contains a large pro¬ portion of gelatine, and very little albumen, fibrin, or os¬ mazome. In adult age, however, the gelatine is very scanty, and the fibrin is abundant. The albumen and gelatine found in muscle seem to be derived chiefly from the filamentous tissue and the aponeurotic intersections. During life the muscular fibre possesses the property of shortening itself or contracting under certain conditions. These may be referred to the following heads: dhe will in the voluntary muscles; 2d, proper fluids in the involuntary muscles, as the blood to the heart, articles of food or drink in the stomach, chyme in the small intes¬ tines, excrement in the large intestines, urine in the blad¬ der, &c.; 3J, mechanical irritants in all muscles; kth, chemical irritants; and, bth, morbid products generated in the course of disease. This property of contracting has received various names: contractility, vis contractilis of L. Bellini; irritability of Glisson; vis vitalis of De Gorter and Gaubius; excita¬ bility, mobility, vis insita, vis propria of Haller; and the organic contractility of Bichat. It is peculiar to muscular fibre, and is found in no other living tissue. The inquiry into the properties peculiar to muscles, and the influence of the brain and nerves over muscular con¬ traction, form an interesting subject of investigation, on which many facts have been communicated since the time of Haller and Whytt, and especially within the last ten years by Nysten, Le Gallois, Wilson Philip, Bell, Magen- die, Flourens, Fodera, and Rolando. But it is too exten¬ sive to be considered in this place; and, for information Ana Mi e. ANATOMY. Genal on the subject, I refer to the ordinary physiological tnatiiy. works, and to those journals in which these researches are s~ detailed.1 Mule. musc]es have been divided, according to the man¬ ner in which the phenomena of contraction take place, into, ls£, muscles obedient to the will, or voluntary; 2o?, muscles not under the influence of the will, or involuntary; and, 3 ' gress as a process of repair when bones are divided,broken, Ge or otherwise destroyed or removed. AnatbJ From the first formation of the embryo to the termina¬ tion of foetal existence, and thenceforth to the completion?0111 of growth, the bones undergo changes in which various ev stages may be distinguished. In the first weeks of foetal existence it is impossible to recognise any thing like bone; and the points in which the bones are afterwards to be developed consist of a soft homogeneous mass of animal matter, which has been designated under the general name of mucus. Some time between the fifth and the seventh week, in the situation of the extremities, may be recog¬ nised dark opaque spots, which are firmer and more solid than the surrounding animal matter. About the eighth week, the extremities may be seen to consist of their com¬ ponent parts, in the centre of each of which is a cylindrical piece of bony matter. Dark solid specks are also seen in the spine, corresponding to the bodies of the vertebrae; and even the rudiments of spinous processes are observed in the shape of minute dark points. In the hands and feet rings of bone are seen in the site of the metacarpal and metatarsal bones. All the joints consist of a semi-consistent jelly- like matter, liberally supplied by blood-vessels. At ten weeks the cylinders and rings are increased in length, and are observed to approach the jelly-like extremities, which are acquiring the consistence of cartilage, and when divided present irregular cavities. At the same time the parts forming the head are highly vascular; and between the membranes are deposited minute points of bony matter, proceeding in rays from a centre, which, however, is thin¬ ner and more transparent than the margin. (Howship.) Between thirteen weeks and four months the cavities in the jelly-like cartilaginous matter receive injection. The membranes of the head are highly vascular, transmit¬ ting their vessels through the intervals of the osseous rays, which are occupied abundantly by stiff, glairy, colourless, mucilaginous fluid. In the seventh month the bony cylinder of the thigh¬ bone and its epiphyses contain canals perceptible to the microscope. In the head the bones are proceeding to completion; the pericranium and dura mater are highly vascular; and a quantity of reddish semitransparent jelly between the scalp and the scull, which contain nume¬ rous minute vessels, Mr Flowship regards as the loose cel¬ lular state of the foetal pericranium. This is, however, doubtful. The cylindrical bones have at this period no medullary cavity, but present in their interior a loose bony texture. Between the seventh and eighth months, in a foetus ten inches long, the humerus consists of a cylinder of bone placed between two brownish, firm, jelly-like masses, which correspond to the epiphyses, inclosed by periosteum, which adheres loosely by means of filamentous and vascu¬ lar productions. The radiusisa thin bony rod, also between two jelly-like epiphyses. The ulna is still thinner, more slender and flexible, and even compressible. The interos¬ seous ligament is a continuous duplicature of the perios¬ teum. The metacarpal bones are much as before, only larger. The hands and fingers are complete; but the phalanges consist of minute semi-hard grains, inclosed in periosteum, which forms a general sac to them, and to the intermediate connecting parts. The middle and unguinal phalanges can scarcely be called osseous. The femur, like the humerus, is an osseous cylinder between two jelly-like epiphyses, enveloped in loosely adhering periosteum. I he tibia andfibula are like the radius and ulna. The metatarsal bones are cylindrical pieces, firm, but not very hard. The first phalanx of the toes is complete; the other two, though the toes are fully formed, are much of the consist- ANATOMY. ence of cartilage. The carpal and tarsal bones are in the state of the epiphyses, but of a gray colour. In this state of the osseous system, the periosteum, ane: which is continuous, and appears to make one membrane eve!'e' with the capsular ligaments and the deep-seated portions Ien of the fascia, adheres to the bone chiefly by arteries and filamentous productions; and so loose is this connection, that a probe may be inserted beneath it, and carried round or inwards, unless where these connections are situate. Another point where the periosteum adheres firmly is at muscular insertions, to the humerus at the insertion of the deltoid, and to \X\q femur at that of the glutceus. In the vertebral column the bodies of the vertebrae and the spinous plates are formed; and minute specks are be¬ ginning in the site of the transverse processes. In the scull the parietal bones are well-formed shells of bone, though very deficient at the mesial plane, the an¬ terior margin, and the upper anterior angle. The peri¬ cranium is distinctly membranous and vascular; and the red jelly-like fluid noticed by Mr Howship is exterior to this membrane. At the period of birth the cylindrical bones contain tubular canals filled with a colourless glairy fluid, and ter¬ minating in the surface of ossification. As the bones previous to this period are homogeneous, and contain no distinct medullary cavity, but present in their interior a soft or loose bony texture, it is reasonable to suppose that the developement of the longitudinal canals is connected with the formation of the medullary cavity. At birth in ihe femur may be distinguished a medullary cavity begin¬ ning to be formed, about half a line broad, but still very imperfect. After birth the two processes of the formation of tubu¬ lar canals and medullary cavity go on simultaneously; and at the same rate nearly the outer part of the cylin¬ drical bones acquires a more dense and compact appear¬ ance. The epiphyses, also, which are in the shape of grayish jelly-like masses, begin to present grains and points of bone. Previously to this, Mr Howship repre¬ sents them, while still cartilaginous, as penetrated by canals or tubes, which gradually disappear as ossification pro¬ ceeds. The carpal and tarsal bones appear to observe the same course in the process of ossification. In the bones of the scull, however, a different law is observed. The osseous matter is originally deposited in linear tracts or fibres, radiating or diverging from certain points termed centres of ossification. Each bone is com- f ’ pleted in one shell without diploe or distinguishable table. Afterwards, when they are completed laterally, or in the p radiating direction, the cancellated arrangement of the diphe begins to take place apparently in the same manner in which the medullary cavity and compact parts of the long bones are formed. In the process now described, it is important to observe that the bony matter is deposited round the soft parts, and that the cavities, holes, and canals of bones are merely parts in which the previous existence of vessels, nerves, ligaments or tendons, prevents the subsequent formation of bone. It has been generally supposed that the formation of cartilage is a preliminary step to that of bone. This, however, seems to be a mistake, arising from the circum¬ stance that cartilage is often observed to be converted in the living body into bone. Neither in the long nor in the fat bones is any thing like cartilage at any time observed, fhe epiphyses, indeed, present something of the consist¬ ence of cartilage, but it has neither the firmness nor the elasticity of that substance. It is a concrete jelly, after¬ wards to be penetrated by calcareous matter. The flat VOL II. 45 bones are from the first osseous; and though their mar- General gins are soft and flexible, in consequence of their recent Anatomy, formation and moist state, they have still a distinct osse-^^^-7 ous appearance and arrangement, and bear no resemblance ;Bone‘ to cartilage. In short, true bone seems never at any pe- I)ev^loPe* riod of its growth to be cartilaginous. ment. The progressive growth of bones is effected by accre¬ tion of new matter to their extremities. The cylindrical bones elongate by the addition of new matter to the ex¬ tremities of their diajihyses, and the flat bones by the en¬ largement of their margins. The latter fact is establish¬ ed by simple inspection during the process of ossification of the cranial bones. In proof of the former, the expe¬ riment of John Hunter is decisive. In the tibia of a pig he bored two holes, one near the upper, the other near the lower end, with an interval of two inches exactly, and inserted into each hole a small leaden shot. After some time, when the animal had grown, and the length of the bone was increased, on killing it, the space between the leaden shots was found, as at first, to be exactly two inch¬ es,—thereby showing that no elongation had taken place between the perforations. The experiment was often re¬ peated with the same result. The period at which ossification is completed varies in different individuals. It may be said to be indicated by the completion of the medullary canal, by the ossification of the epiphyses, and their perfect union with the osseous cylinder (diaphysis). The first circumstance is indefinite. The two latter, though more fixed, are still liable to great variation. The epiphyses are rarely united before the age of 14 or 15 ; and they may continue detached to the 20th or 21st year. In general, however, they begin to unite or to be knit, as is said, between the 15th and 20th years. That the main agents of original ossification are the pe¬ riosteum and its arteries, the proofs are manifest. The formation of bone can be ascribed to the vessels of two agents only,—the periosteum and the medullary mem¬ brane. That the latter is not concerned in the pro¬ duction of bone in the foetus, must be inferred from the fact that at that period it cannot be said to exist. To the periosteum, therefore, and its vessels must be as¬ cribed the process of foetal ossification. Of this a cu¬ mulative proof is found in the circumstance, that the pe¬ riosteum adheres more firmly at the ends than the mid¬ dle of the bones; and that the pericranium and. dura mater, which perform the part of periosteum to the bones of the scull, are visibly concerned in the formation and succes¬ sive enlargement of these bones. But though the peri¬ osteal vessels are the main agents of ossification original¬ ly, there is reason to believe that the medullary vessels contribute to its growth and nutrition after it is formed. This may be inferred from the phenomena of fractures, of diseases of the bones, and of those experiments in which the medullary membrane is injured. Ihe perios¬ teum, however, does not act by ossification of its inner layers, as Duhamel, misled by a false analogy between the growth of trees and bones, laboured to establish. A peculiar form of the osseous system requiring notice are the sesamoid bones. These, which derive their name from their minuteness, a grain), most of them, excepting the knee-pan, being ot the size of a grain or pea, are confined to the extremities, and are situate chiefly in positions in which they give points of sup¬ port to the tendons of the flexor muscles. (Tendons of the gemelli, tibialis posticus, peronoeus long us, &c.) The peculiarity of these bones is, that they are formed invariably in the substance of fibrous organs, as tendons in the case of the knee-pan and the sesamoid bones of the gemelii, tibialis posticus, and pevonccus longus ; or ligaments 746 ANATOMY. General in the case of those situate between the chiro-phalan- goal and podo-phalangeal articulations. With this pe- Bone culiarity their mode of ossification corresponds. At Develope- albuminous or fibro-albuminous, in process of time ment. Junctions. they are penetrated by calcareous matter, and present an osseous texture, which, however, is much less firm than that of genuine bone. The period at which this deposi¬ tion commences and is completed varies in different in¬ dividuals ; and hence scarcely in any two persons of the same age is the number of sesamoid bones the same. Though the patella may be ossified at the 20th year, the minute sesamoid bones are sometimes not formed before the 30th or even the 40th. In the patella, when ossified, we find a medullary organ ; but it is uncertain whether the others acquire this mark of osseous character. These bones resemble the epiphyses in uniting, when divided, by fibro-albuminous matter. 4. The bones of which the skeleton consists are united in two modes ; l,s£, by movable junction (diarthrosis) ; ral tween the bifid margin of another, as the azygos pro- Ge cess of the sphenoid bone is received by the plates of Ana ^v. the vomer ; (schindylesis.) The third mode of immov- ^ ~ able union is by implantation or insertion (gomphosis), asBon' the teeth are inserted into the alveolar cavities of the su-Jun!)ns' perior and inferior maxillary bones. The following table exhibits a view of these modes of junction, with their appropriate appellations. 2dly, by immovable junction (synarthrosis). Both modes of union bear the general name of articulation, though this term would with greater propriety be confined to the first or movable union. By . this are connected all the bones concerned in locomotion, and some of those devot¬ ed to the organic functions, as the ribs and the lower jaw. The second is employed in the union of bones forming the walls of cavities. In the movable union, the articular surfaces are unit¬ ed in two modes. In the first, in which one bone moves on the other with different degrees of freedom, the arti¬ cular surfaces are covered by cartilage and synovial mem¬ brane, and the bones are united by ligaments and tendons. In the second (amphiarthrosis), in which the motion is confined to a species of torsion or imperfect rotation, the bones are united without articular surface by fibro-carti- lage. The first is exemplified in the articulations of the extremities ; the second is seen in the union of the bodies of the vertebrae and the bones of the pelvis. The several forms of movable union with free motion, or articulations proper, may be referred to four heads, ac¬ cording to the nature of the motions performed. The first is the motion of radio-central opposition, or pivot-motion in every direction, in which the bone moves in its articular cavity, not only backwards and forwards, or by flexion and extension, but by abduction and adduction, and, by the succession of these motions, may describe a cone with the apex at the joint, or what is termed circumduction. This most extensive form of motion is found in the scapulo¬ humeral and coxo-femoral articulations only. The second form of articular motion is antero-posterior opposition, or cardinal motion (cardo, a hinge), in which the bones move on each other by flexion and extension, as a gate on its hinges. This, which is sometimes named limited opposition, is found in the femoro-tibial and humero-cu- bital joints, and all those which undergo flexion and ex¬ tension. The third form of motion is that of rotation, in which the bone revolves on its axis,—an infrequent vari¬ ety, confined chiefly to the humerus and femur. The fourth, which is the gliding motion, though common to all articular surfaces, is nevertheless the peculiar motion of the carpal and tarsal bones. In the immovable union the surfaces are united in three modes. The first is by mutual indentation, or what is named suture (sutura vera,), in which the margin of one bone is dovetailed by alternate serrated teeth and notches, into that of another. The second is by juxta¬ position (harmonia), in which the margin of one bone is simply fitted to that of another. A peculiar variety of this is, when the acute margin of one bone is received be- JUNCTIONS OF BONES. I. IMMOVABLE ; (sYNABTHROSIS.) Continuous Bony Surfaces, united by Bone and Membrane. aS.

The Carnal and Tarsal Bones; the Oblique Processes of the Ver¬ tebrae. Teeth. (Dentes.) Every tooth consists of two hard parts; one external, Lx white, uniform, somewhat like ivory; the other internal, similar to the compact structure of bone. The first, which is named enamel, is seen only at the crown of the tooth, the upper and outer part of which consists of this substance. It is white, very close in tex¬ ture, perfectly uniform and homogeneous, yet presenting a fibrous arrangement. Extending across the summit of the tooth in the manner of an incrustation, it is thick above, and diminishes gradually to the root, where it dis¬ appears. This fact is demonstrated by macerating a tooth in dilute nitric acid, when the bony root becomes yellow, while the crown remains white. . The enamel is not injectible, and is therefore believed to be inorganic. It is also filed and broken without being reproduced; nor does it present any of the usual proper¬ ties which distinguish organized bodies. The piercing sensation which is communicated through the tooth from the impression of acids seems to depend on the mere che¬ mical operation, and not on the physiological effect. Gn ANATOMY. Ger al the whole, the enamel is to be viewed as the inorganic Anaijny- result of a process of secretion or deposition. The bony part of the tooth is the root and that internal Tt h’ part which is covered on the sides and above by the ena¬ mel. It consists of close-grained bony matter, as dense as the compact walls of the long bones, or the petrous portion of the temporal bone. The fibres which are said to be seen in it are exactly of the same nature as those in bone. In the interior of the bony part of each tooth is a ca¬ vity which descends into the root, and communicates at its extremity with the outer surface by openings corre¬ sponding with the number of branches into which the root is divided. This cavity, which is large in young or new¬ ly formed teeth, and small in those which are old, contains a delicate vascular membrane, which has been named the pulp of the tooth. It is best seen by breaking a recent tooth by a smart blow with a hammer, when the soft pulpy membrane may be picked out of the fragments by the forceps. It then appears to be a membranous web with two surfaces, an exterior adhering to the bony sur¬ face of the dental cavity by minute vessels; the other in¬ terior, free, and, so far as can be determined of a body so minute, resembling a closed sac. The developement and growth of the teeth is a process of much interest. At what time the first rudiments of teeth appear seems not to be determined with accuracy. In the foetus, be¬ tween the seventh and eighth month, I can merely dis¬ tinguish in the centre of the vascular membrane of the al¬ veolar cavity a minute firm body like a seed. I have, hovyever, seen the crowns of teeth formed in foetuses which, I have reason to believe, had not attained the seventh month. But whatever may be the exact period, the process is nearly as follows, i While the bones of the upper and lower jaw are in the process of formation between the third and fourth months, (fourth and fifth, Bichat, tom. iii. p. 93,) a series of soft, membranous, vascular sacs inclosed within the general cavity of the periosteum, may be recognised at their lower and upper margins, which are still without those osseous plates which afterwards constitute the al¬ veoli. Each of the sacs now mentioned consists, like a serous membrane, of two divisions,—one external, attached to the periosteum, the other folded within it, and forming a closed cavity. The outer or periosteal deposits in the in¬ tervals between each sac, bone, which eventually consti¬ tutes the transverse septa of the alveoli. From the inside of the inflected portion the process of dentition commences some time between the fifth and seventh month, by the de¬ position of matter from the vessels at the lowest point of the alveolar division of the sac. This matter is to consti¬ tute the crown of the tooth, which is invariably formed first. After the deposition of the first portions, these are pushed upwards by the addition of successive layers below them, and necessarily carry the inflected part of the sac before them. As this process of deposition advances, the tooth gradually fills the sac, and rises till it reaches the level of the alveolar margins. If a tooth be examined in situ, near the period of birth, it is found to consist of the crown, with portions of enamel descending on every side, and forming a cavity in which a cluster of blood-vessels proceeding from the sac is lodged. In the mean time, bone is deposited from the periosteal division all round each sac, so as to form the alveoli. After the enamel has been deposited the bone begins to be formed; and as this process advances, the tooth is still forcibly thrust upwards by the addition of matter to Jts r°ot. When the latter is well completed, the vessels 747 become smaller and less abundant, until, when the tooth General is perfect, they shrink to a mere membrane, which lines Anatomy, the cavity of the tooth, and still maintains its original connection with the alveolar membrane, by the minute Teeth- vascular production which enters the orifice or orifices of the root. Physiological authors have thought it important to mark the period at which the teeth appear at the gums; and in general this takes place about the sixth or seventh month after birth. This mode of viewing the process of dentition, however, gives rise to numberless mistakes on the period of teething. The process, as we see, commences in the early period of foetal existence; and the time at which they appear above the gums varies according to the progress made in the womb. In some the process is ra¬ pid, in others it is tardy; and even the stories of Richard III. and Louis XIV. receive confirmation from the fact of 19 examples cited by Haller, of infants born with one or more teeth above the gum. Generally speaking, the crown is completed at the period of birth ; and, according as the formation of the root advances with rapidity or slow¬ ly, dentition is early or late. What is here described is the process of the formation of the first or temporary set of teeth, which consist, it is well known, of twenty. In that of the second set the same course is observed. In the same manner is observed a row of follicular sacs, though not exactly in the original alveoli, yet attached to the sacs of the temporary teeth by vascular membranes; in the same manner deposition begins at the bottom of the free surface of the sac by the formation of the crown ; and in the same manner the crown is forcibly raised by the successive accretion of new matter to its base. The moment this process commences, a new train of phenomena takes place with the primary teeth. The follicular sacs of the new or permanent teeth are liberally supplied with vessels for the purpose of nutrition; and as these blood-vessels increase in size, those of the tempo¬ rary teeth diminish; and the supply of blood being thus cut off, the latter undergo a sort of natural death. The roots which, as being last formed, are not unfrequently incomplete, now undergo a process of absorption ; and the tooth drops out in consequence of the destruction of its nutritious vessels. Some authors have ascribed this ex¬ pulsion to pressure, exercised by the new tooth. They forget, however, that before the new tooth can exert any pressure, it must be in some degree formed; and to this a vascular system is indispensable. The increased number of the teeth when permanent, the enlargement of the jaws, and the consequent expansion of the face, though interesting, are foreign to the present inquiry. Gristle, Cartilage. ( Cartilago,— Tissu Cartilagineux.) The cartilaginous system or tissue is found at least in Cartilage, three different situations of the human body; Is#, on the articular extremities of the movable bones; 2c?, on the connecting surfaces or margins of immovable bones ; 3c/. in the parietes of certain cavities, the motions and uses of which require bodies of this elastic substance. The organization of gristle is obscure and indistinct. On examination by the microscope, its surface is pearl- white, uniform and homogeneous, firm and glistening, with numerous minute pores. William Hunter represents the articular cartilages as consisting of longitudinal and transverse fibres. (Phil. Trans, vol. xlii.) Herissant re¬ presents those of the ribs as composed of minute fibres mutually aggregated into bundles connected by short slips, and twisted in a spiral or serpentine direction. (Mem. de TAcad. 1748.) By Delasone, the articular cartilages 74S ANATOMY. General are said to consist of a multitude of minute threads, Anatomy. mutually connected and placed at right angles to the plane of the bone, but so as to radiate from the centre to Caiti age. circumference. (Ibid. 1752.) The general fact of fibrous structure is confirmed by Bichat, who states that it is possible to recognise longitudinal fibres, which are intersected by others, oblique or transverse, but without determinate order. In its purest form no blood¬ vessels are seen in it, nor can they be demonstrated by the finest injections. In the margins of those pieces of gristle, however, which are attached to the extre¬ mities of growing bones, blood-vessels of considerable size may often be seen, even without the aid of. injection. In young subjects a net-work of arteries and veins, which is described by Hunter under the name of ciTculus avticuli vasculosus, may be demonstrated all round, the margin of the cartilage at the line between the epiphysis and it. They terminate so abruptly, however, that they cannot be traced into the substance of the latter. The most certain proofs, however, of the organic structure of this substance are the serous exudation which appears in a few seconds on the surface of a piece of cartilage after division by the knife; and the fact that it becomes yellow during, jaun¬ dice, and derives colour from substances found in the blood. Neither absorbents nor nerves have been found in it. The cellular texture said by Bichat to form the mould for the proper cartilaginous matter appears to be imaginary. * The articular cartilages adhere to the epiphyses by one surface, which consists of short perpendicular fibres placed parallel to each other, and forming a structure like the pile of velvet. This is easily demonstrated by maceration, first in nitric acid, and then in water. The free or smooth surface is covered by a thin fold of synovial membrane, which comes off in pieces during maceration. The exist¬ ence of this, though recently denied by Gordon, was ad¬ mitted by William Hunter, and may be demonstrated either by boiling, maceration, or the phenomena of inflam¬ mation, under which it is sensibly thickened. All other cartilages are enveloped, unless where they are attached to bones, by a fibrous membrane, which has been there¬ fore named perichondrium. The existence of this may be demonstrated by dissection, and also by boiling, which makes it peel off in crisped flakes. The chemical properties of cartilage have not been ac¬ curately examined. Boiling shows that it contains gela¬ tine ; but as much of the matter is undissolved, it may be inferred that it is under some modification, or united with some other principle, perhaps albumen. Immersion in nitric acid or boiling fluids induces crispation, and it dries hard and semitransparent like horn. Fibro-Cartilage, Chondro-Desmoid Texture. (Cartilago Fibrosa,— Tissu Fibro- Cartilagineux.) Fibro-car- Intermediate between the cartilaginous and the fibrous tiiage. tissues, Bichat ranks that of the fibro-cartilages, which comprehends three subdivisions: ls£, the membranous fibro-cartilages, as those of the ears, nose, windpipe, eye¬ lids, &c.; 2c?, the inter-articular fibro-cartilages, as those found in the temporo-maxillary and femoro-tibial articula¬ tions, the intervertebral substances, and the cartilaginous bodies uniting the bones of the pelvis ; 3c?, certain portions of the periosteum, in which, when a tendinous sheath is formed, the peculiar nature of the fibrous system disap¬ pears, and is succeeded by a substance belonging to the order of fibro-cartilages. Beclard follows Meckel in rejecting the first subdivi¬ sion, the individuals of which are quite similar to ordinary cartilage, in wanting the distinct fibrous structure, and being covered by perichondrium, the fibres of which have caused Gei them to be regarded as fibro-cartilages. On this principle Ana1 Beclard gives the following view of the fibro-cartilages. \st, Fibro-cartilages free at both surfaces; those in the^ltr' form of menisci, which are placed between the articularU a° surfaces of two bones (Jibro-cartilagines inter-articulares). These are seen in the temporo-maxillary, sterno-clavicular, and femoro-tibial articulations, and occasionally in the acromio-clavicular and the ulno-carpal joints. These liga¬ ments are attached either by their margins or their ex¬ tremities, and are enveloped in a thin fold of synovial membrane. 2d, Fibro-cartilages attached by one surface. Of this description are those employed as pulleys or grooves for the easy motion of tendons; for instance, the chondro-desmoid eminences attached to the margin of the glenoid cavity for the long head of the biceps, and at the sinuosity of the ischium for the tendons of the obturatores. 3d, Fibro-cartilages, which establish a connection between bones susceptible of little individual motion, as the inter¬ vertebral bodies; or which unite bones intended to remain fixed, unless under very peculiar circumstances, as those which form the junction of the pelvic bones. (Symphysis pubis ; sacro-iliac synchondrosis.) The peculiarities of these substances consist in their partaking in different proportions of the nature of carti¬ lage and white fibrous tissue, and, consequently, in possess¬ ing the toughness and resistance of the latter with the elasticity and flexibility of the former. The structure of the fibro-cartilaginous tissue is easily seen in the interver¬ tebral bodies, and in the cartilages uniting the pelvic bones. In the former, white concentric layers, consisting of cir¬ cular fibres placed in juxtaposition, constitute the outer part, while the interior contains a semifluid jelly. The concentric fibrous layers are cartilage in a fibrous shape. In the latter situation the fibrous structure is equally dis¬ tinct, while the cartilaginous consistence shows the con¬ nection with that organic substance. A similar arrange¬ ment is remarked in the inter-articular cartilage of the temporo-maxillary articulation, and in the semilunar car¬ tilages of the knee-joint. In all, the fibrous is said to pre¬ dominate over the cartilaginous structure. Their physical properties are distensibility and elasticity. Though they are at all times subjected to considerable pressure, they speedily recover their former size. Though their chemi¬ cal composition is not exactly known, they evidently con¬ tain much gelatine. Gland. Glandular System. (Glandulce.) The name gland, though rather vaguely used, may be Gla properly restricted to designate organs of a definite structure, consisting of arteries, veins, and excretory tubes, arranged in a peculiar manner, and destined to separate from the blood a fluid of peculiar chemical an physiological properties. The organs of this description may be arranged in two general divisions,—the follicular glands, or those which occur in an isolated form; and the conglomerate glands, or those which, being of larger volume, are understood to consist of numerous small glands combined in one general organ. The former em¬ braces the sebaceous glands of the skin and the muci parous glands of mucous membranes; in the latter are comprehended the lacrymal and salivary glands, vvi the tonsils, the pancreas, the liver, the kidneys, the tes¬ ticles of the male, and mammce of the female, and per haps the prostate gland. To a third head, denomina ed that of imperfect glands, Meckel refers such 05Ta., as the thymus, the suprarenal capsules, the thyra1 > and the spleen. But since the term imperfect imp here a contradiction, and since it is by no means asc ANATOMY. 749 geii-al tained, either that these organs secrete, or that their isaviy- secretions are removed by the lymphatics, it is manifest that they cannot be justly associated with the organs above defined as examples of glands. The follicular glands, though most minute, are never¬ theless distinguished by the most simple and intelligible structure. They consist of small hollow spherical sacs, or minute membranes moulded into the saccular form, in the attached surface of which are distributed numerous minute arteries and veins, and the free surface of which is smooth and covered with the fluid secreted. The quantity of vascular substance with filamentous tissue surrounding the attached surface of these glands, makes them occasionally project from the surface of the mem¬ brane to which they are attached. In ordinary circum¬ stances, however, they cause no elevation, and appear in the form of simple sacs with a narrow orifice. These glands belong to two textures only of the animal body,— the skin and the mucous membrane. In the former they are named sebaceous glands, from the fluid which they se¬ crete containing a small portion of fatty matter. In the latter they are named follicles, crypts, or muciparous glands. In certain regions of the mucous membranes, for in¬ stance in the male urethra, the crypts are arranged in such a manner that they constitute large sinuous cavities, the free surface of which secretes serous mucus copious¬ ly. These cavities, which have the further effect of in¬ creasing much the superficial extent of the membrane, are denominated lacunae. The peculiarity of this form of mucous gland appears to consist in its membranous sac having unusual extent, and consequently in the glandular vessels being more expanded than in the ordinary glands. The structure of the conglomerate glands is more com¬ plicated. Each gland consists of numerous minute por¬ tions of definite figure, named lobules; and each lobule may be resolved into granules, also of definite shape, in¬ timately connected by filamentous tissue. These granules, which have since the time of Malpighi been denominated acini, are found to consist of clusters of minute arteries and veins aggregated together, with minute tubes for con¬ veying away the secreted fluid. On these points anato¬ mists are agreed. They are seen most distinctly in the liver and kidney, and may be demonstrated in the pan¬ creas, testicles, and female breast, by injection. Every acinus, in short, may be said to consist of two parts, a vas¬ cular or supplying, and a tubular or excreting. On the manner in which these two parts of the acinus communicate, however, there is less certainty and preci¬ sion. In this difficulty, as the point is scarcely a matter of observation, conjecture has been resorted to; and the opinions of anatomists have been divided between two parties. According to one, at the head of which may be placed Ruysch, Haller, William Hunter, and Hewson, the minute arteries terminate directly in the excretory ducts, without intermediate substance. According to the other opinion, which is that of Malpighi, between the arteries and the excretory tubes there are placed minute mem¬ branous vesiculce or pouches, in the substance of which the arteries, still more minutely divided, are distributed, and from the free surface of which the process of secre¬ tion goes on. In short, each acinus, according to Mal¬ pighi, is a separate follicle, and the conglomerate glands consist merely of numerous follicles, combined so as to form a large general secreting organ. Between these two views of the intimate nature of the glandular tissue there is less difference than at first sight might be imagined. The chief difference is in the ulti¬ mate arrangement of the glandular capillaries. According to the view of Malpighi, these capillaries are arranged in clusters, as it were, round the beginning of the excretory General pore, so that even in this condition the termination of the Anatomy, former class of vessels is the commencement of the latter. Conversely, it may be said, that since the delicate mem- Gland* brane in which the secreted fluid first appears neces¬ sarily receives the capillary terminations, the latter can¬ not be said to communicate directly with the excretory tubes. The correct view of the matter is, that by the term vesicles are not to be understood large sacs, but merely the rounded recess of the membrane which forms the excretory tubes. Further, since the researches of Hewson and Monro show that in the kidney and the tes¬ ticle the arteries are convoluted, it may be inferred that this is the character of the capillary arrangement of the glands; and that it is requisite to the performance of the process of secretion that the vessels be disposed in such a tortuous manner as to prevent too rapid motion of the blood. The conglomerate glands, we have seen, consist chiefly of minute vascular ramifications infinitely subdivided. In all the glands, excepting the liver, these vessels consist of arteries to convey blood to the organ, and veins to re¬ turn it to the system ; and in all the glands, excepting the liver, it is a peculiar circumstance that the same arterial trunk conveys blood for nourishing the gland, and for sup¬ plying the materials of the secretion. All the secretions, therefore, excepting that of the liver, are derived from arterial blood. The liver alone, besides receiving a con¬ siderable artery, derived from the coeliac trunk, is remark¬ able for being chiefly supplied with blood from a large venous trunk, formed by the union of the veins of the stomach and spleen, and the mesenteric and mesocolic branches, and which after this union is again subdivided into ramifications in the substance of the gland. Injection shows that the branches and twigs of this vein anastomose freely with those of the hepatic artery; and though it might be imagined that the latter is intended chiefly to nourish the gland, and the former to supply the materials for secretion, this circumstance, with the fact that in some rare instances the vena portae is not distributed in the liver, shows that at present this opinion must be adopted with caution. Besides arteries, veins, and excretory tubes, glands are supplied with lymphatic vessels, which are arranged in two sets, superficial and deep. The former are confined to the surface of the organ, over which they may be seen creeping in every direction, and belong chiefly to the membranous coverings of the glands. The deep-seated lymphatics are those which penetrate the substance of the glands, and in general accompany the large blood¬ vessels. Every gland receives a proportion of nervous branches, generally from the nerves of the sympathetic system. These branches accompany the blood-vessels in penetrat¬ ing the substance of the glands, and are distributed much in the same manner as the arteries before their ultimate division. They exercise some influence over the process of secretion ; but the nature and extent of this influence are still undetermined. Each gland contains a quantity of filamentous tissue, which envelopes the blood-vessels, tubes, lymphatics, and nerves, and constitutes a large proportion of the mass of the gland. The simple tissues, thus united, are inclosed in a general membranous covering, which also partly con¬ tributes with these tissues to retain it in its situation. These membranous coverings vary in different glands. In the liver and pancreas it is the peritoneum ; the kidneys are inclosed in a peculiar tunic; the testes are contain¬ ed in a fibrous membrane; and the acini of the lacrymal 750 ANA T O M Y. General and mammary glands appear to be covered by a form of condensed filamentous tissue. CHAP. III. ENVELOPING TISSUES. Skin. (Cutis, Pellis.) Cutaneous Tissue, Dermal Tissue. (La Peau, Tissu Dermoide,—Die Haut, Das Fell.) Pell, old English; with its appendages, Scarf-skin or Cuticle, Nail, Hair. ( Cuticula, Epidermis,— Tissu Epi¬ dermoids et Tissu Pileux.') Skin. Skin has been said to consist of three parts, true skin (cutis verd), mucous net (rete mucosum), and scarf-skin or cuticle. Haller, Camper, and Blumenbach, are inclined to deny the existence of the mucous net in the skin of the white, and to admit it in that of the negro only; and in point of fact, indeed, its existence has been demonstrated in the negro race only, and inferred by analogy to exist in the white. “ When a blister has been applied to the skin of a negro,” says Cruikshank, “ if it has not been very stimulating, in twelve hours after a thin transparent grayish membrane is raised, under which we find a fluid. This membrane is the cuticle or scarf-skin. When this with the fluid is removed, the surface under these appears black; but if the blister had been very stimulating, another membrane, in which this black colour resides, would also have been raised with the cuticle. This is rete mucosum, which is itself double, consisting of another gray transparent membrane, and of a black web very much resembling the pigmentum nigrum of the eye. When this membrane is removed, the surface of the true skin, as has been hitherto believed, comes in view, and is white like that of a European. The rete mucosum gives the colour to the skin; is black in the negro; white, brown, or yel¬ lowish in the European.” (Experiments on the Insensible Perspiration, &c. London, 1795.) Bichat denies the existence of a mucous varnish (corpus mucosum) such as Malpighi describes it, and regards the vascular surface of the corion as the only mucous net. According to Chaussier the skin consists of two parts only, the derma (fo^iu, cutis vera) or corion, and the epi¬ dermis, cuticle, or scarf-skin; the first embracing the or¬ ganic elements of this tissue; the second being an inorganic substance prepared by the organic, and deposited on its surface. This opinion is adopted by Gordon, according to whom the skin consists of two substances placed above each other, like layers or plates (lamince), the inner of which is the true skin, the outer the cuticle or scarf-skin. Beclard, on the contrary, thinks that a peculiar matter, which occasions the colour by which the several races are distinguished, is found between the outer surface of the corion and the cuticle; and that no fair race is destitute of it except the albino, the peculiar appearance of whom he ascribes to the absence of the mucous net of the skin. The corion of the human skin (pellis, corium, derma, cutis vera) seems to consist chiefly of very small dense fibres, not unlike those of the proper arterial coat, closely interwoven with each other, and more firmly compacted the nearer they are to its outer or cuticular surface. The inner surface of the corion is of a gray colour; and in al¬ most all parts of the body presents a number of depres¬ sions varying in size from ygth to y^th of an inch, and consequently forming spaces or intervals between them. These depressions, which correspond to eminences in the subjacent adipose tissue, have been termed areolce. They are wanting in the corion of the back of the hand and foot only. The outer or cuticular surface of the corion is smooth, of a pale or flesh-red tinge, and is much more vascular than its inner surface. It presents further a number of minute conical eminences (papillae), which, according to Gem i the recent observations of Gaultier and Dutrochet, are Anatc y. liberally supplied with blood-vessels, and are the most vas-^^X cular part of this membrane. In the ordinary state of cir- culation and temperature during life these eminences are on a level with the surrounding corion ; but when the sur¬ face is chilled, this membrane shrinks, while the papillae either continue unchanged or shrink less proportionally, and give rise to the appearance described under the name of goose skin (cutis anserina). This surface was said by the older anatomists to present numerous orifices or pores; but according to Gordon, if we trust to observation, no openings of this kind can be recognised, either by the eye or the microscope, except those of the sebaceous follicles. The hairs, indeed, are found to issue from holes in the corion, but they fill them completely. In certain situations, for instance at the entrance of the external auditory hole, at the tip of the nose, on the margins of the eyelids, in the armpits, at the nipple, at the skin of the pubes, round the anus and the female pu¬ dendum, are placed minute orifices, from which exudes an oleaginous fluid, which is quickly indurated. These openings lead into the cavities of small sacs called follicles (folliculi) or sebaceous glands (glandules sebacece). These sacs, the structure of which is noticed above, consist of hollow surfaces secreting an oleaginous fluid, which is progressively propelled to the orifice, where it soon un¬ dergoes that partial inspissation which gives it the seba¬ ceous or suet-like aspect and consistence. The corion is liberally supplied with blood-vessels, nerves, and absorbents. After a successful injection, its outer surface appears to consist of a uniform net-work of minute vessels, subdivided to an infinite degree of deli¬ cacy, and containing during life blood coloured and co¬ lourless. It can scarcely be doubted that this vascular net-work (rete vasculosum) is the only texture correspond¬ ing to the reticular body of the older anatomists. It is well known that this membrane, when boiled suf¬ ficiently long, is converted into a viscid glutinous liquor, which consists chiefly of gelatine (Chaptal, Seguin, Hat¬ chett, Vauquelin, &c.), and that glue is obtained from it for the purposes of art. As, however, in these operations a portion of matter is left undissolved, and as glue is com¬ pletely soluble in water, while skin resists it for an inde¬ finite time, it may be concluded, that though the chief constituent of the corion is gelatine, it is under some pe¬ culiar modification not perfectly understood. The union of this organized gelatine with the vegetable principle denominated tannin forms leather, which is insoluble in water. _ • J Cuticle or scarf-skin (epidermis, cuticula) is a semi-Cutic transparent, or rather translucent layer of thin light- coloured matter, extended continuously over the outer surface of the corion. Its thickness varies, being thinnest in those parts least exposed to pressure and friction, but thickest in the palms and soles. It is destitute of blood¬ vessels, nerves, and absorbents; and there is reason to believe, from observing the phenomena of its reproduc¬ tion, that it is originally secreted in the form of a semi¬ fluid viscid matter by the outer surface of the corion ; and that, as it is successively worn or removed by attrition, it is in like manner replaced by a constant process of secretory deposition. This semifluid viscid matter, which in truth is found between the outer surface of the corion and the firm cuticle, is the substance mentioned by Mal¬ pighi, and so often spoken of as the mucous net (corpus mucosum). It is inorganic; and it is impossible to ex¬ plain its production otherwise than by ascribing it to the outer vascular surface of the corion, . ANATOMY. 751 Gieral Cuticle is rendered yellow and finally dissolved by im- Aitomy. mersion in nitric acid. It is also dissolved by sulphuric ^.^^acid in the form of a deep brown pulp. These, and some i n> other experiments performed by Hatchett, show that it consists chiefly of modified albuminous matter. This description shows, that if strict observation he trusted, the mucous net has no existence, at least in the European. In the Negro, Caffre, and Malay, however, a black membrane is said to be interposed between the co- rion and cuticle, and to be the cause of the dark com¬ plexion of these races. On this subject I refer to the de¬ scription given by Cruikshank, which is the best (Ex¬ periments, &c. p. 31, 41, and 43) ; the Essay of M. Gaul¬ tier, already quoted; and the observations of Beclard. What is found in the skin of the mixed or half-caste races, i. e. the offspring of an African and a European, or of a mulatto and European ? and how is the transition be¬ tween this colouring layer and its insensible diminution effected ? Na. Nail is a substance familiarly known. On its nature and structure we find many conjectures, but few or no facts, in the writings of anatomists; and almost all that has been written is the result of analogical inference ra¬ ther than of direct observation. It is known that the nails drop off with the scarf-skin in the dead body; that they are diseased or destroyed by causes which act on the outer surface of the corion, and produce disease of the cuticle; and that, if forcibly torn out, the surface of the corion to which they were attached bleeds profusely and inflames. In other respects they are inorganic ; but these facts warrant the conclusion that the root of the nail is connected with the organic substance of the corion, and that the whole substance is the result of a process of se¬ cretion similar to that by which the cuticle is formed. According to the experiments of Hatchett, they con¬ sist of a substance which possesses the properties of coa¬ gulated albumen, with a small trace of phosphate of lime. Ha The root of a hair is not only that part which is con¬ tained in the bulb, but the portion which is lodged in the skin. The middle part and the point are those which project beyond the surface of the skin. The bidb is a small sac fixed in the inner surface of the corion, in the contiguous filamentous tissue, and in which the root is implanted. Every hair is cylindrical, tapering regularly from the root to the point, and solid, but containing its proper co¬ louring matter in its substance. The colour varies, but the root is always whitish and transparent, and softer than the rest; the fixed or adhering part of the root is almost fluid. When hair is decolorized, it becomes trans¬ parent and brittle, and presents a peculiar silvery-white colour; and as hairs of this kind are few or abundant, it gives the aspect of gray, hoary, or white hair. The bulb, though visible in a hair plucked out by the root, is too small in human hair to be minutely examined ; and Chirac, Gaultier, and Gordon, have therefore de¬ scribed its structure and appearances from the bulbs of the whiskers of large animals, the seal for example, in which it is much more distinct. According to researches of this kind, every bulb forms a sort of sac or follicle, which consists of two tunics, an inner one, tender, vascu¬ lar, and embracing closely the root of the hair; and an outer, which is firmer and less vascular, and surrounds Are inner one, while it adheres to the filamentous tissue and the inner surface of the corion. When the hair is¬ sues from the bulb, it passes through an appropriate canal of the corion, which is always more or less oblique, but which, as has been already said, it fills completely; and General it afterwards passes in a similar manner through the scarf- Anatomy, skin. Nervous filaments have been traced into the bulbs of the whiskers of the seal by Rudolphi and the younger Hain Andral. The bulb or follicle, in short, is organic, and forms by secretion the inorganic hair. The structure of hair appears to be either so simple, or so incapable of being further elucidated, that anato¬ mists have not given any facts of consequence regarding it. Its outer surface is believed to be covered with im¬ bricated scales, because in moving a single hair between the finger and thumb it follows one direction only. Hair is believed to be utterly inorganic, though the phenomena of its growth, decoloration, and especially of the disease termed Polish plait (plica Polonica), have led various authors to regard it as possessed of some degree of vitality. These phenomena, however, may be explain¬ ed by the occurrence of disease in the bulbs or generat¬ ing follicles. Hair is insoluble in boiling water ; but Vau- quelin succeeded in dissolving it by the aid of Papin’s digester. From the experiments of this chemist, and those of Hatchett, it may be inferred that hair consists of an animal matter, which appears to be a modification of albumen, a colouring oil, and some saline substances. Mucous Membrane, Villous Membrane. (Membrana 3Iu- cosa, M. Mucipara, M. Villosa,— Tissu Muqueux, Bi¬ chat.) The organic tissue or membrane to which the name of Mucous mucous or villous has been applied, consists of two greatniemt>rane. divisions, the gastro-pulmonary and genito-urinary. The first or gastro-pulmonary division comprehends that membranous surface which commences at the vari¬ ous orifices of the face at which it is contiguous with the skin, and is continued through the lacrymal and na¬ sal passages, and even the Eustachian tube, by the larynx on the one hand to the windpipe and bronchial mem¬ brane, and by the oesophagus on the other through the entire tract of the alimentary canal, at the opposite ex¬ tremity of which it is again identified with the skin. The distribution of the second division, or the genito¬ urinary mucous membrane, is slightly varied according to the differences of sex. In the male it is connected with the skin at the orifice of the urethra, from which it pro¬ ceeds inwards toward the bladder, sending previously small prolongations through ducts on each side of the veru montanum, from which it is believed to be continued through the vasa deferentia, to the vasa efferentia of the testicle. Continued over the inner surface of the urinary bladder, it is prolonged through the ureters to the pelvis and infundibula of the kidney. In the female, besides passing in this direction, it ascends into the womb, and passes through the Fallopian or uterine tubes, at the up¬ per extremity of which it terminates in an abrupt opening into the sac of the peritoneum—the only instance in the whole body in which a mucous and serous surface com¬ municate freely and directly. These two orders of membranous tissue have each two surfaces, an attached or adherent, and a free one. I he adherent surface is attached, \st, to muscles, as in the tongue, most of the mouth and fauces, oesophagus, and whole alimentary canal, and the bladder; 2d, to fibrous membranes, as in the nasal cavities and part of the la¬ rynx, in which it is attached to periosteum or perichon¬ drium, the palate, ureter, and pelvis of the kidney; 3c?, to fibro-cartilages, as in the windpipe (trachea), and bronchial tubes.

Sen'll In certain points, where a communication is observed naUiy- between the general mucous surface and the cavities or recesses of particular regions, anatomists, unable to de- [uc° monstrate a mucous membrane, have inferred its exist- em 11 'ence as a continuation of the general surface. In the tympanal cavity, to which the Eustachian tube leads, the existence of a mucous or fibro-mucous membrane is rather presumed from analogy than proved by obser¬ vation. We know that, where the biliary and pancreatic ducts enter the duodenum, and for a considerable space towards the liver, the interior appearance is that of a fine mucous surface provided with lacuna and villosities; but it is impossible to say at what point of the hepatic duct, or of the smaller canals of which it is formed, the mucous membrane terminates. The tracheal membrane, when traced to the bronchial divisions, presents no arrange¬ ment, either of papilla, piles, or villosities; and nothing is perceived except a smooth uniform surface, of a colour between gray, dun, and red or purple, which is moistened with a viscid semi-transparent fluid, and which is as like the peritoneum as the intestinal mucous membrane. Lastly, the situation where the existence of the mucous system, though believed, is most uncertain, is in the interior of the vasa deferentia, where they take their ori¬ gin from the vasa efferentia of the testis. Regarding the organization of these tubes, no sensible evidence can be obtained, and whatever is stated concerning it is the re¬ sult of analogical inference. Though these membranes have been designated by the general name of mucous, the action of their surface is not in every situation the same. It is not easy to limit the signification of the term mucus ; for this fluid varies in the nasal passages, in the trachea and bronchial membrane, in the oesophagus, stomach, and intestines, and in the urin¬ ary bladder and ureters. But it may be stated that many parts of the two mucous surfaces never in the healthy state secrete any modification of this animal matter; and in others the membrane is almost always moistened by a different fluid. The mucous or villous membrane of the eyelids is never in the healthy state occupied by mucus, but is uniformly moistened with the tears ; the membrane of the mouth and throat is moistened with saliva only; the urethra presents a peculiar viscid fluid, which seems to exude from many minute vessels opening along its sur¬ face, as in the lacuna, but which is widely different from mucus. All those parts, in short, which are not in per¬ petual, but only occasional, contact with foreign or se¬ creted substances, seem to present no mucus in the healthy state; whereas the surfaces of the stomach, intestines, gall-bladder, and urinary bladder, are constantly covered with a quantity, more or less considerable, of this animal secretion. The chemical properties of mucous membranes are com¬ pletely unknown. The analysis of the fluid secreted by them has been executed by Fourcroy, Berzelius, and others, but is foreign to the subject of this article. That the mucous membranes are liberally supplied with blood by vessels both large and numerous, is proved not only by the phenomena of injections, but by the red co¬ lour of which many of their divisions are the seat. This coloration, as well as the injectibility, is not indeed uni¬ form ; for in certain regions mucous surfaces are pale or hght blue, in others their redness is considerable. dims, in those regions in which the mucous membranes coalesce with the periosteum, forming fibro-mucous mem- branes, e. g. in the facial sinuses, the tympanal cavity and the mastoid cells, the colour is pale blue, or approaching to light lilac.

Examined in the gastro-enteric mucous membrane, in which they are most numerous, these vessels are found to consist of an extensive net-work of capillaries divided to an infinite degree of minuteness, mutually intersecting and spreading over the upper or outer surface of the mucous corion. This vascular net-work, though demon¬ strated by Ruysch, Albinus, Haller, and Bichat, has been beautifully represented in the delineations of Bleuland, who thinks he has traced their minute ramifications into the villi. These minute vessels are derived from larger ones, which creep through the submucous cellular tissue, and penetrate the mucous corion, the substance of which receives few or no vessels, to be finally distributed at its exterior surface. The arrangement of the vessels which supply the mu¬ cous surfaces is peculiar. Penetrating, in the form of considerable trunks, between the folds of the serous mem¬ branes, they divide in the subserous cellular tissue into branches of considerable size; and here they form those numerous anastomotic communications which constitute the arches so distinctly seen in the ileum. From the con¬ vexity of these arches are sent off most of the small ves¬ sels, which are then fitted, after passing through the muscular layer and the submucous tissue, to enter the mucous corion. The capillary terminations, then, of these arteries, and their corresponding veins, constitute the physical cause of the coloration of the mucous membranes. This colora¬ tion, however, is not at all times of the same intensity in the same membrane, and varies chiefly according to the state of the organ which the membrane covers. The co¬ loration of the gastro-enteric mucous membrane under¬ goes, even within the limits of health, many variations. Thus, according to the absence or presence of such fo¬ reign substances as are taken at meals, the mucous mem¬ brane is pale, or presents various shades of redness. At the period of menstruation the uterine mucous membrane becomes red and injected. Pressure on any of the venous vessels renders the mucous membranes blue, purple, or livid, as is seen in prolapsus, and more distinctly in as¬ phyxia, in which all the mucous membranes assume a livid tint. (Bichat.) The varieties of red colour observed in the gastric mucous membrane by Dr Yellowly are to be ascribed partly to the latter cause, partly to the vascular redness which the presence of foreign bodies occasions. (Medico-Chirurg. Trans, vol. iv. p.371.) The pulmonary di¬ vision of this membrane is of an ash-gray or dun colour, inclining to pale blue or light red. These colours vary, nevertheless, according to the facility or the difficulty with which the blood moves through the pulmonary ca¬ pillary system. It is also freely supplied with blood-ves¬ sels derived chiefly from the bronchial arteries. These vessels, after accompanying the bronchial tubes and their successive subdivisions, divide into minute branches which penetrate the mucous corion, which here is white, dense, and fibrous, and after anastomosing with the capillaries of the pulmonary artery and veins, form a minute delicate net-work on the outer surface of the pulmonary mucous membrane. According to Reisseissen, to whom we are indebted for a careful examination of these vessels, a suc¬ cessful injection of them from the bronchial arteries ren¬ ders the whole mucous membrane of the bronchi entirely red to the unassisted eye.

Mucous •j'hg serous or sero-mucous fluid with which they membrane. are mojstene(j iias ]e(i every author almost, and among the rest Haller and Bichat, to infer the existence of arteries with orifices, or what are termed exhalant vessels. It has been admitted, nevertheless, more on analogical than di¬ rect proofs. The injections of Bleuland, the only experi¬ ments, after those of Kawe Boerhaave, which tend to con¬ firm the conclusion, require nevertheless to be repeated and varied.1 That lymphatics are distributed to mucous membranes, is a point well established. Cruikshank saw the lympha¬ tics proceeding from the pulmonic mucous membrane loaded with blood in persons and animals dying of hae- moptoe. Their existence in the gastro-enteric mucous membrane has been long established. The mucous surfaces are also freely supplied by nervous twigs and filaments, derived in general from the nerves of automatic life. It is a mistake, nevertheless, to ascribe to these filaments the sensibility and other properties of the mucous membranes, which possess intrinsically certain vital properties independently of the nervous filaments with which they are supplied; and the principal use of these filaments appears to be to regulate these properties, especially that of secretion. The connection between the mucous membranes and the skin was first demonstrated by Bonn, who traces their mutual approximation and reciprocal transition into each other, and represents the former as an interior production of the latter, enveloping the internal as the skin incloses the external organs. This view has been adopted by Meckel and Bedard, to whom I refer for the proofs of its accuracy. I cannot conclude the subject, however, with¬ out observing that one of the most conclusive arguments in its favour is derived from the circumstances of the de- velopement of the intestinal canal during the first months of uterine life. The history of this curious process, which has been investigated by Wolff, Oken, and Meckel, shows that at this period the gastro-enteric mucous membrane, which is previously formed by the vitellar membrane of the ovum, and the allantois or vesical membrane, which afterwards forms the genito-urinary mucous surface, are in direct communication on the median line, and afterwards at the navel, with the skin or exterior integument. Serous Membrane, Transparent Membrane. (Membrana Pellucida, M. Serosa.— Tissu Sereux.) Serous The pleura and peritoneum are the best examples of membrane, the tissue which has been named serous, from the fluid with which it is moistened, and which may be termed transparent or diaphanous as its distinctive character. The distribution or mechanical arrangement of these membranes is peculiar, and though not well understood by anatomists, till Douglas, by his description of the perito¬ neum, rendered it clearer, may now be said, by the la¬ bours of Hunter, Carmichael Smyth, and Bichat, to be quite intelligible. In this, nevertheless, there are certain peculiarities which may perplex the beginner, and prevent him from obtaining at first a clear idea of the distribution and configuration of the pellucid membranes. Thus they have neither beginning nor termination; they have neither orifice nor egredient canal; and they are not continuous Get al with any other membrane or texture. Anat iy. Every serous membrane consists of a hollow sac every-^ where closed, and to the cavity or interior surface ofSerni which there is no natural entrance; a circumstance frommem'ne’ which they have been denominated shut sacs (sacci occlusi; sacs sans ouverture). In every serous membrane one part is inverted or inflected, or reflected, as is commonly said, within the other, so that the inner surface of the former part is applied with more or less accuracy to the inner or like surface of the latter. This mode of disposition has suggested the homely and trite, but not inappropriate comparison of a serous membrane to a night-cap, one half of which is folded or doubled within the other, so that while one half of the inner surface is applied to the re¬ maining half, no communication exists between the inner and the outer surface. Every serous membrane, in short, is a single sac, one half of which is doubled within the other. In every serous membrane the outer surface of the un- reflected portion is applied over the walls of the region which the serous membrane lines, while the outer surface of the inflected portion is applied over the organ or organs contained in that region. From this arrangement it re¬ sults that each organ covered by serous membrane is not contained in that membrane, but is on its exterior surface, and that of every organ so situate, one part at least, viz. that at which its vessels and nerves enter, is always un¬ covered. Thus the lungs are on the outer surface of the pleura; the heart is on the outside of the pericardium; the stomach, intestines, liver, spleen, and pancreas, are on the outside of the peritoneum; and the testicles are on the outside of the perididymis. In the same manner the lungs, though invested by pleura before and behind, at their apex and their base, are uncovered at their roots, or the points where the bronchial tubes and great blood¬ vessels enter their substance; the heart is uncovered by pericardium at the upper part of the auricular cavities; and the intestinal canal is uncovered along the whole ol that longitudinal but tortuous line by which the mesentery is attached, and at which its proper vessels and nerves are transmitted. To comprehend more distinctly the arrangement of the pellucid membranes, it is expedient, by an effort ol abstraction, to trace the course of any one of them, having previously thrown out of the question the means by which their interior free surface is exposed. In this mental process it is requisite to remember that there is no initial point save what is arbitrarily made. If, for example, the course of the pleura be traced, the mem¬ brane presents no natural boundary from which the ana¬ tomist is to commence his demonstration; and he must fix artificially on any point which he finds most con¬ venient for the purpose. Commencing with this under¬ standing, from the circumference of the spot termed root of the lungs, the membrane may be traced first along the internal surface of the chest formed by the ribs and in¬ tercostal muscles, forwards to the sternum, upwards to the first rib and apex of the thoracic cavity, downwards to the diaphragmatic insertions, and over the surface ot that muscle, and the outer surface of the pericardium again to the circumference of the root or connection ol the lungs. From this point again it may be traced over the surface and between the lobes of these organs, both o 1 Experimcntum Anatomicum, quo Artcriolarum Lymphaticarum existentia probabiliter aistruitur, &c. a Jano Bleuland, M.

Trajecti, 1797* ANATOMY. 755 W which, as already stated, are thus situate on the outside natny- of the pleura. The course first described is that of the r/^ unreflected or exterior division of the pleura. The second, «u - or that over the organ covered, is the course of the inflect- ;nll; iC' ed or doubled portion of the membrane, which is thus ne¬ cessarily smaller, and less extensive, than the former. The arrangement thus sketched, which may be easily shown to be applicable to all the serous membranes, de¬ monstrates their twofold character of lining the walls of a cavity and covering the organs contained. From an idea of this property, the old anatomists applied to them the epithet of membrance succingentes. In tracing the course of the serous membranes, the anatomist observes that they present productions which float with more or less freedom in the cavity formed by the free surface, and which may be generally shown to consist of two folds of the single membrane produced beyond the inclosed organ, but still maintaining the unity of the membrane. Of these prolongations, the most dis¬ tinct examples are the epiploon and the appendices epiploicce of the peritoneum. Less manifest instances are the adi¬ pose folds of the pleura near the mediastinum, and the bladder-like appearance at the base of the heart, within the pericardium. The synovial fringes in the interior of the synovial membranes, which belong to a subsequent head, are nevertheless of the same general character. Between the folds of these productions there is invariably more or less adipose substance, which indeed is observed in some quantity in various parts of the filamentous tissue on the outer surface of the serous membranes in general. Every serous membrane I have above represented as a hollow sac everywhere continuous, and the outer surface of which has no communication with the inner. To this character the only exception is the peritoneum in the female, which is perforated at two points, corresponding to the upper extremity or orifice of the Fallopian or ovi- ferous tubes. This has been already mentioned as the only spot at which the mucous and serous surfaces com¬ municate directly with each other. Every serous membrane consists of a thin, colourless, transparent web or pellicle, through which the tissue of the subjacent organ or parts may be easily (recognised; and every serous membrane presents two surfaces, an at¬ tached or adherent, and a free or unadherent. The attached surface, which is also termed its outer one, is that by which it is connected to the tissue or organ which it covers; it is somewhat irregular, flocculent or tomentose, and is evidently connected by fine filamentous tissue. The degree of attachment is very variable in dif¬ ferent membranes, and in different points of the same membrane. In general, serous membranes adhere much less firmly to the walls of cavities than to the surface of the contained organs. Thus, the abdominal peri¬ toneum and the costal pleura are more easily removed than the intestinal peritoneum and the pulmonic pleura. The peritoneum adheres feebly to the bladder, to the liver, and to the pancreas—more intimately to the different regions of the intestinal tube, and seems to be almost identified with the substance of the female organs of generation. From the interior of the capsular and from the vaginal coat, it is almost impossible to detach the serous pellicle. The former, however, is peculiar in having between the serous surface and the fibrous mem¬ brane no filamentous tissue, upon the abundance or de¬ ficiency of which the degree of adhesion depends. The free or unadherent or inner surface is very smooth, polished, and uniform; moistened with a watery fluid, from which it derives its shining appearance; and des¬ titute of fibres or any other trace of organic structure. From this smooth, polished aspect, which is a peculiar attri- General bute of the free surface of serous membrane, all the organs Anatomy, covered by it derive their glistening appearance. Thus the exterior surface of the lungs derives its appearance from Serous the pleura, the heart from the pericardium, and the livermembrane' and intestinal canal from the peritoneum. A successful injection of size or turpentine, coloured with vermilion, brings into view, so many capillary blood-vessels in this membrane, that it might be supposed at first sight to con¬ sist entirely of minute arteries and veins. Further, by proper management, lymphatics may be injected in it with quicksilver to a degree equally minute and delicate. From these experiments, therefore, it may be concluded that serous membrane is chiefly composed of minute arte¬ ries and veins conveying colourless fluids, and of vessels connected with the general trunks of the lymphatic system. Whether it contains any thing else but vessels of this kind, or has a proper, substance or tissue, remains to be ascer¬ tained. Though nerves are often seen passing along their outer or attached surface to the neighbouring tissues, none have hitherto been traced either into the pleura or peritoneum. By most of the older anatomists, and among others by Flaller, serous membrane is considered as of the nature of filamentous tissue or cellular membrane, more or less closely condensed {tela cellulose?, stipatd) ; and this view is adopted and maintained by Bordeu, Bichat, Meckel, and Beclard, the last of whom, however, thinks they par¬ take of ligamentous characters. Macerated, they become soft, thick, and pulpy; and are finally resolved into floc¬ culent filamentous matter. In the course of decomposi¬ tion in the dead subject they first lose their glistening aspect, then become covered by a foul, dirty coating of viscid matter, which appears to exude from their surface ; and eventually they are dissolved into shreds. Immer¬ sion in boiling water renders them thick, firm, and some¬ what crisp. When dried they become thin, clear, and transparent, and, if preserved from humidity or the attacks of animals, may remain long unchanged. The experiments of Hatchett, Fourcroy, and Vauquelin, show that they contain gelatine and a little albumen; but no precise in¬ formation on their chemical composition has yet been given. The principal character of the serous membranes is that of isolating the organs which they cover, and to the struc¬ ture of which they are adventitious, and forming shut ca¬ vities, in which there is incessant exhalation and absorp¬ tion. In some instances they evidently contribute to fa¬ cilitate the mutual motions of contiguous and corre¬ sponding surfaces. From their free surfaces is secreted a fluid containing a small portion of albumen (Hewson, Experimented Inquiries, vol. ii. chap. vii.; Bostock, Ni¬ cholson’s Journal, vol. xiv. p. 147, and Medico-Chirurgi- cal Transactions, vol. iv.), which is greatly augmented du¬ ring the state of disease. The mode of developement of the pellucid membranes is not well ascertained. The investigations regarding organogenesy by Oken, Meckel, and Tiedemann, disclose facts which induce Meckel to hazard the opinion that some of them are not at all times shut sacs. I doubt, however, whether the fact which he adduces for this purpose im¬ plies the open condition of the pericardium and the peri¬ toneum. In the case of the former the developement of the heart proceeds from the basis generally, without affect¬ ing the integrity of the investing membrane. In the case of the latter there is more reason to believe that, at the navel, at least, the peritoneum is either open, or is con¬ tinuous with the vitellar membrane. In the foetus the serous membranes are so thin, that 756 ANATOMY. General Anatomy. Serous membrane they are much more transparent than in the adult. In small animals also, they are more transparent than in large, and in cold-blooded animals than in the mammifer- ous. Of some also the disposition varies at different pe¬ riods. Thus the descent of the testicle,—a process which has been well explained by Albinus, Haller, Wrisberg, and Langenbeck,—is attended with a remarkable change in the arrangement of that portion of peritoneum which the gland impels before it. Synovial membrane. Synovial Membrane. (Membrana Synovialis; Bursa Mucosae.') Bichat enumerates several circumstances in which he conceives that serous and synovial membranes differ from each other. Gordon, who doubts how far the distinctions are well founded as the basis of anatomical arrangement, admits, however, the following peculiarities. Synovial membrane resembles serous membrane in being a thin, transparent substance, having one smooth free sur¬ face turned towards certain cavities of the body, and an¬ other connected by delicate cellular tissue to the sides of these cavities, or to the parts contained in them. But it differs from serous membrane in the following circum¬ stances. Is*, It possesses little vascularity in the healthy state; no blood-vessels are almost ever seen in it after death, nor can they be made to receive the finest injec¬ tion. 2d, Its lymphatics are quite incapable of demon¬ stration. 2>d, Very delicate fibres, like those of cellular substance, or like the finest filaments of tendon, are dis¬ tinctly seen in it after slight maceration, kth, It is con¬ siderably less strong than serous membrane. On these grounds, therefore, synovial membrane is to be anatomi¬ cally distinguished from serous membrane. The synovial membrane, as described above, is found not only in each of the movable articulations, but in those sheaths in which tendons are lodged, and in which they undergo considerable extent of motion, and in certain situations in the subcutaneous filamentous tissue. The distribution of the synovial membranes is much the same in all these situations. They are known to line the ligamentous apparatus of each joint, capsular and funicular; and they are also continued over the cartila¬ ginous extremities of the bones of which the articulation consists. This continuation, which was originally main¬ tained by Nesbitt, Bonn, and William Hunter, and was demonstrated by various facts by Bichat, has been lately questioned by Gordon and Magendie, the former of whom especially thinks it unsusceptible of anatomical proof. The cartilaginous synovial membrane is certainly not so easily demonstrable as the capsular, for the same reason which I have already assigned regarding the difficulty of isolating the capsular pericardium, the ovarian peritoneum, and the serous covering of the tunica albuginea,—the want of filamentous tissue. The presence of synovial membrane in the articular watches and chronometers. BOOK II. DESCRIPTIVE, PARTICULAR, OR SPECIAL ANATOMY. Special Anatomy may be defined to be that science, the province of which is to determine the shape, situation, and component parts of the several textures and organs of which the human body consists. In the course of this, however, it is requisite to premise some observations on the external shape of the body, and the different regions into which it has, for the sake of greater precision, been divided. cartilages is nevertheless established by sundry facts. 1^, Get a| If a portion of articular cartilage be divided obliquely, Anai iv. and examined by a good glass, it is not difficult to recog-O nise at one extremity of the section a thin pellicle, differ- S'Vno'1 ing widely in aspect, colour, ancUstructure, from the blu-mem nc' ish-white appearance of the cartilage. 2d, If the free surface of the cartilage be scraped gently, it is possible to detach thin shavings, which are also distinct from carti¬ lage in their appearance. The free surface of the cartilage is totally different from the attached surface, or from a section of its substance, and derives its peculiar smooth polished appearance from a very thin transparent pellicle uniformly spread over it. Uh, If articular carti¬ lage be immersed in boiling water, this thin pellicle be¬ comes opaque, while the cartilage is little changed. 5^, Immersion in nitric or muriatic acid, which detaches the cartilage from the bone, gives this surface a cracked ap¬ pearance, which is not seen in the attached surface, and which is probably to be ascribed to irregular contraction of two different animal substances. &th, The existence of this cartilaginous synovial membrane is demonstrated by the morbid process with which the tissue is liable to be affected. On the whole, therefore, little doubt can be en¬ tertained that the representation of their course, as given originally by Nesbitt, Bonn, and Hunter, is well founded. The same views may be applied to the synovial linings of the tendinous sheaths, which are equally to be regarded as shut sacs. Attached to the free surface of each synovial mem¬ brane is a peculiar fringe-like substance, which was long supposed to be an apparatus of glands (glands of Havers) for secreting synovial fluid. It is now known that these fringes are merely puckered folds of synovial membrane, and that, although synovia is abundantly secreted by them, this depends merely on the great extent of surface which is the necessary consequence of their puckered arrangement This arrangement is easily demonstrated by immersing an articulation containing the fringed processes in clear water, when they are unfolded and made to float, and show their connections, figure, and terminations. They are analogous to the free processes of serous membranes, and like them are double, and contain adipose matter. The synovial sheaths (bursae mucosae) are very nume¬ rous, and are generally found in every tendon which is exposed to frequent or extensive motion. Though the fluid prepared by these membranes has been examined by Margueron, Fourcroy, John Davy, Orfila, and other chemists, it cannot be said that its che¬ mical composition is accurately determined. It is said to contain water, albumen, incoagulable matter regarded as mucilaginous gelatine, a ropy matter, and salts ot. soda, lime, and some uric acid. On the presence of the incoa¬ gulable gelatine depends its utility in diminishing friction in the finer kinds of metallic machinery employed m The external shape of the human body is so well known, that it is superfluous to describe it. Besides its division into right and left halves, anterior and posterior surfaces, it is divided into head, trunk, and extremities. Hie trun ' is subdivided into neck (collum), chest (thorax, and belly (abdomen). The extremities are subdivide .into thoracic or upper, and pelvic, abdominal, or low er. ANATOMY. 757 S ;ial The shape of the head is ellipsoidal, or oblong sphe- Anp"1/’ roidal; the greater diameter being antero-posterior, and the transverse smallest. The neck is cylindrical, spreading out above and below. The shape of the trunk is that of an irregular cylinder, flattened before and behind, broad above, and tapering below tbe chest, but expanding again at the pelvis. The extremities affect the cylindrical form, inclining to the conical. Db:«c- These several parts may be still further subdivided, tiouito The head is distinguished into two great divisions, the ^£S,|S• head proper, and the face. The former corresponds to the scalp, and may be divided into coronal, temporal, parietal, and occipital regions. The coronal or syncipital may be reckoned from the anterior margin of the scalp to the site of the anterior fontanelle, or the line named the coronal suture. Behind this to the crown (vertex), and downwards on each side, are the parietal or lateral regions; from the parietal and frontal is the temporal; from the crown to the flex¬ ure of the neck is the hind-head or occipital (occiput); from the last point to the level of the shoulders is the cervix ; on eacn side are the lateral regions of the neck; and before is the laryngeal, jugular, or anterior (jugulum). The face consists of the brow, front or forehead (from), with the glabella or mesophryon at its base, in the mid¬ dle, and the eyebrows (supercilia) on each side; the nose (nasus), the upper lip (supralabium), the lower lip (infralabium), the chin (mentum), the cheeks (gence), the chops (buccce), and the upper jaw (malce), and lower jaw (maxilla). The chest, besides its distinction into right and left halves, anterior and posterior surfaces, and upper and lower boundaries, may be distinguished into a sternal re¬ gion in the middle (sternum), a mammary region on each side, an axillary region, a costal region, a hypochondriac region, a scapular region, and a vertebral region. The abdomen may be distinguished into regions in the i following manner. The triangular space between the false ribs and navel, commonly named the pit of the sto¬ mach, is the epigastric region (scrobiculus cordis, epi¬ gastrium). Below this, in the centre, is the umbilical (umbilicus), with the iliac region or flanks (ilia) on each side, and the hypogastric (hypogastrium) below. Behind, on each side of the vertebral column, are the loins (lumbi). Next to the abdomen is the pelvis, the posterior lateral parts of which are the buttocks (nates), the anterior the pubes, and the inferior the hips or ischiatic regions (ischia), with the perinceum in the middle between them. In each pectoral extremity are recognised the following divisions; the shoulder (humerus), the armpit (axilla), the arm (brachium), the elbow (cubitus), the fore-arm (antebrachium), the wrist (carpus), and the hand (manus). The latter is subdivided into the fore-wrist (metacarpus), the fingers (digiti), the palm (vola), and the back-hand (thenar). Each abdominal extremity presents the following sepa¬ rate regions; the haunch (coxa), the thigh (femur), the knee (genu), the ham (poples), the leg (tibia), of which there is the muscular part or calf (sura), the ankle exter¬ nal and internal (malleolus externus et internus), the foot (pes), subdivided into the ankle-joint (tarsus), the foot- joint (^metatarsus), the toes (digiti pedis), with dorsal or upper surface, and palmar surface or sole (solea). These divisions, though not so numerous as they have been made by some, are sufficiently so for the purpose of general anatomical description. Where more minute dis¬ tinction is requisite, it shall be introduced as we proceed. The stature of the body varies in the t\Vo sexes, in individuals, in families, in tribes, and in nations. The Romans, when they first visited Gaul, remarked the Special gigantic stature of the ancient inhabitants of that coun- Anatomy, try compared with themselves; and, generally speak- mg, the modern Italians, though by no means a pure or unmixed breed from the ancient stock, are a di- minutive race. The Germans, and most of the English and Irish, are rather tall. The inhabitants of Finland are distinguished for their great stature, amidst the dwarf¬ ish tribes by which they are surrounded. In general, the Europeans are taller than the Asiatics. The average height of the adult male varies from 5 feet Height or 8 inches to 5 feet 10 or 11 inches, or even to 6 feet.length- The dimensions of different parts vary according to those of the whole body; but the following measurements of a male of 5 feet 8 inches, and one of 5 feet 11 inches, may communicate some idea of the length of different regions of the body. Inches. Inches. Total height... 68-00 71-00 Between the tips of the middle fingers, with the arms extended 68-00 72-75 From the crown to the pubes 34-00 35-00 From the crown to the lower tip of the chin 9-75 9-00 From the tip of the chin to the top of the breast 3-85 3-25 From the top of the breast to the pit of the stomach. ...i 6-08 9-75 Between the pit of the stomach and the navel 6-08 7-00 Between the navel and top of the pubes... 6-08 6-75 Between the top of the shoulder and the bend of the elbow. 12-06 12-00 From the bend of the elbow to the top of the hand 10-02 10-5 The hand, from the wrist to tip of middle finger 7-75 7-375 Between the top of the thigh inside and the knee inside 14*06 17-00 From the knee inside to the sole 18-05 20*00 The foot, from the heel to the point of the great toe 9-75 10-00 The average height of the female varies from 5 feet 3 inches to 5 feet 5 inches and 5 feet 7 or 8 inches. A woman of 5 feet 10 inches is unusually tall. The length of the different regions is proportionally less than in the male. The length of the body previous to adult age varies with the period of life. The length of an embryo of three weeks,, represented by Soemmering, is about ^ of an inch ; one of eight weeks is about 1 inch ; and one at the end of the fifth month is about 10 inches. According to Burns, however, the length of the foetus in the fifth month does not exceed 6 or 7 inches; in the sixth it is about 8 or 9, in the seventh about 12, and in the eighth about 15 inches. At the period of birth, the average length, ac¬ cording to Roederer, is about 20^ inches. The only part of the foetus of "which it is important to determine the average dimensions at the period of birth is the head. Its largest diameter, which is that from the crown to the chin, is in general about 5 inches. The transverse diameter between the parietal protuberances is at the same time about 31 inches. Of 60 male and 60 female infants born at the full time, whose heads were measured by Dr Clarke, the circumference passing through the occipital process and the middle of the brow was at an average 13-8 inches, while the arch from ear to ear over the crown was 7-32 inches. One measured 15 inches in circumference, and one 81 inches from ear to ear; but 758 ANATOMY. Special none were under 12 inches in the one direction, or 6^ Anatomy, inches in the other. it is wen established that there is a difference in the average dimensions of the male and female, even in the foetal state. Roederer found the mean length of 16 male children born at the full time to be 20|f inches, and of 8 females only 20^; and of the 60 male and 60 fe¬ male infants measured by Dr Clarke, the average circum¬ ference was 14 inches in the former, and only 13^ in the latter; and the parietal arch was 7J inches in the former, and 7£ in the latter. Of 120 infants, in 6 only, which were males, did the circumference of the head exceed 14| inches. Weight. The weight of the adult male varies from 9 stone to 11 or 12. Ten stones, or 140 lbs., may be stated as the average. The female weighs about 8 stone, and rarely more than 10. After the age of 35 or 40, when fat begins to be de¬ posited, the weight rises considerably; and the average weight at this age is from 13 to 14 stones. In some ex¬ traordinary examples of corpulence, combined with large stature, the weight of the body amounts to 20 and 25 stones. The average weight of the fcetus in the early months is uncertain. According to Mr Burns, it weighs about 2 oz. in the 12th week; about 1 lb. in the 6th month; and about 4 or 5 lbs. troy in the 8th month. At the period of birth the mean weight is about 7 lbs. avoirdupois. Dr William Hunter states, that of .several thousand new-born perfect infants weighed at the British Hospital in London by Dr Macaulay, the smallest was about 4 lbs., the largest about 11 lbs. 2 oz., and the greater number varied from 5 to 8 lbs. avoirdupois. He knew no instance of a new¬ born infant weighing 12 lbs. Of 60 male and 60 female infants weighed by Clarke, the lightest was 4 lbs., the heaviest 10 lbs., and the average 7 lbs. 13 dr. avoirdupois. The average weight of 26 children at the natural period, weighed by lloederer, was about 6^ lbs.; the lightest about 51 lbs., and the heaviest about 8 lbs. The difference between the weight of the male and fe¬ male infant at birth is estimated by Dr Clarke at about 9 oz. avoirdupois, which agrees with the results obtained by Roederer. In the case of twins, the average weight of each twin is in general less than that of children born at single births; but the combined weight of both is greater. Dr Clarke found the average weight of 12 twins to be 11 lbs. avoirdupois each pair; the heaviest being 13 lbs., and the lightest 8^ lbs. Mr Burns, however, states that he has known instances in which each twin was rather above than below the usual weight of a single-birth child. Special Anatomy has been divided, according to the classes of textures of which the human body is composed, into different parts, with appropriate denominations. Thus the anatomy of the bones has been named osteology, oste¬ ography, and skeletology ; while that of the soft parts in general has been denominated sarcology. Where more minuteness is attempted, the anatomy of the soft parts has been still further subdivided into that of the ligaments, syndesmology; the muscles, myology; the vessels, an- giology; the nerves, neurography and neurology; the membranes, hymenology; the glands, adenography and adenol'ogy ; and the internal organs, splanchnology. Though these are convenient terms to designate the several divisions of Special Anatomy, they afford little as¬ sistance in the general arrangement of the subject. It is justly observed by Bichat, that this arrangement, if such it can be named, is objectionable, by separating different organs which ought to be united. It is indeed remarkable only for connecting organs by arbitrary, and often unna- Spa tural principles; and though it may answer in a subor- Anatc dinate manner, it is unfit to furnish the principles of a^^^ general and natural mode of arrangement. The most eligible method is that which arranges the organs according to their physiological purposes,—a me¬ thod adopted by Haller and Soemmering, but which re¬ quired the hand of Bichat to give it its full and perfect developement, and which has since been adopted from this author by Cloquet. According to this method, the organs of the human body may be arranged in three great classes: first, those pertaining to the animal functions, or which establish the connection between the individual and the objects of the external world—the organs of relation; secondly, those pertaining to the organic functions, or which tend to the continuance of the individual—the organs of nutrition; and, thirdly, the organs relating to the continuance of the species—the organs of reproduction. The first class con¬ tains the organs of locomotion, speech, and sensation ; the second those of digestion, circulation and absorption, respi¬ ration, and secretion ; and to the third are referred the organs of generation. This method may not be altogether free from objec¬ tions ; several of which are anticipated by Bichat. It is sufficient, however, to observe that it is less objection¬ able than any other ; and one of its advantages is, that it furnishes a clearer and more precise idea of the connec¬ tion of the different classes of organs of the animal body than any other yet proposed. This method of arrangement may be conveniently ex¬ hibited in the following table. I. Organs pertaining to the Animal, Voluntary, or Relative Functions. {Instruments—Bones, Cartilages, Ligaments, and Fibro-cartilages.

ANATOMY. 759 Sji'ial hnmy- ANATOMY OF THE ORGANS OF THE ANIMAL, VOLUNTARY, OR RELATIVE FUNCTIONS. The organs belonging to the functions of animal life are those of locomotion, sensation, voice, and innervation. These organs are distinguished by two general characters, symmetry of form and harmony of action. By the first is meant that each organ possesses similar parts on each side of the mesial plane. By the second is meant that the action of that part which is on the right side of the mesial plane corresponds with that on the left. CHAP. I. THE ORGANS OF LOCOMOTION. The organs of locomotion may be arranged in two orders, active and passive. The first are the agents of motion, or the organic substances which produce motion: the se¬ cond are the bodies moved, or the instruments of motion. The muscles, strictly speaking, are the former, though to these are added certain appendages. The bones and their appendages constitute the second. With the latter order of parts it is usual to begin the business of special anatomy, for obvious reasons. The bones are at once the most durable and regular in shape of all the organic solids; and as an intimate relation sub¬ sists between their mechanical figure and the soft parts connected with them, the knowledge of the former con¬ stitutes the best introduction to that of the latter species of organs. SECT. I. OSTEOLOGY, SKELETOLOGY. The assemblage of bones composing the human body constitutes the skeleton, which, like the body, is divided j into head, trunk, and extremities. The length of the skeleton is about an inch less than that of the body; that is, the skeleton of an individual 5 feet 8 inches in height is about 5 feet 7 inches long, and of one 6 feet, about 5 feet 11 inches long. The weight of the skeleton varies at dif¬ ferent periods of life. That of a middle-sized adult ranges between 160 and 200 ounces. A male skeleton, measur¬ ing 5 feet 6 inches long, I found to weigh 168 ounces, or 101 ibStj avoirdupois. The number of separate pieces amounts to 254, of which 56 belong to the trunk, 60 to the head, 72 to the pecto¬ ral extremities, and 66 to the pelvic. Of these several parts, the trunk is the most important, because, ls£, it is developed before the head or extremities; and, 2dly, be¬ cause if we look to its place in the animal kingdom ge¬ nerally, it is the most essential and constant, and pre¬ sents the general modulus or type according to which the osseous pieces composing the head are constructed. The Trunk. Th 1 unk. The trunk of the skeleton consists of three parts, the spine or vertebral column, the chest or thorax, and the pelvis. §. 1. The Spinal or Vertebral Column. (Spina Torsi; Vertebrce.) Tlie vertebral column, situate in the posterior part of the trunk, the length of which it determines, unites the head to the pelvis, supports the former, and is supported by the latter. When completely developed, it consists of 29, and rarely of 30 pieces, named vertebrce (spondyli, anmdu'hoi), from the circumstance that each admits of a slight*degree of rotatory motion. Twenty-four of these bones, which are in the healthy adult separate, are de- Special nominated true vertebrae (vertebra: verce). The 25th, Anatomy, named the sacrum, though in adult life forming a single bone, consists in early life of four separate pieces, which Theverte" become consolidated, and are therefore named false ver- br£e“ tebr marks the lower termination of that cavity. In the former case it is closed by the posterior sacro-coccy- geal ligament. The sides of the sacrum, which are rough, and of an ir¬ regular cuneiform shape, present two surfaces,—one ante- The os coccygis. rior, something cartilaginous, for articulating with the ilia'c bones,—the other posterior, marked by two deep sinu¬ osities, in which are lodged the sacro-iliac ligaments. The inferior termination of the sides tapers towards the apex or coccygeal end. The surface is rough for the insertion of the sacro-ischiadic ligament, and it is terminated by a notch for the exit of the fifth pair of posterior sacral nerves. The structure of the sacrum, like that of the vertebrae, is cancellated, and most loose in the site of the spinal plates and processes. Its mode of ossification is analogous to that of the vertebrae generally. On the middle plane ap¬ pear five points, which correspond to the bodies of the false vertebrae, or the individual bodies of the sacrum ; and on each side of these are formed two others, which become eventually the ridges of bone between the ante¬ rior and posterior sacral holes and the spinal plates. As these enlarge, they coalesce; and consolidating, leave only on the pelvic and dorsal surfaces the rows of holes through which issue the sacral nerves. It hence results that the sacrum is ossified from fifteen separate portions of bone. Besides the muscles connected with the lumbar verte¬ brae, the sacrum gives attachment to part of the glutceus maximus and the pyriformis. The sacrum is attached above to the last lumbar ver¬ tebra by the intervertebral fibro-cartilage, the capsule of the two articular processes, and the yellow ligament of the spinous processes; to the iliac bones by the sacro¬ iliac synchondrosis, and to the coccyx by a similar fibro- cartilage. (Plate XXIV. fig. 1, S.) The coccyx is a symmetrical bone, triangular, occupying the posterior and inferior parts of the pelvis, attached by its base to the sacrum, and with the apex free and slightly incurvated forwards, so as to terminate in a hooked point, which has been supposed to resemble the bill of the cuckoo, (xoxxvj', cuculus.) The anterior or pelvic surface is concave, marked with transverse grooves covered by periosteum, and supporting the lower extremity of the rectum. The posterior or outer surface is convex, gibbous, and unequal, for the in¬ sertion of the sacro-coccygeal ligament and some fibres of the large glutceus, and, like the anterior, is also marked by transverse grooves. ^ The base or upper end of the coccyx is concave be¬ fore for articulation with the sacrum, and presents behind two tubercles continuous with those of the spinal region, and on the sides two notches, which, with those of the sacrum, form holes for the fifth pair of sacral nerves. The margins of the bone are rough, for the attachment of the small sciatic ligament, and meet below at an angle, which is sometimes bifid, sometimes obtuse, and to which the levator ani is attached. The coccyx is generally cellular, with little densit}’’. The transverse grooves by which it is marked indicate its original separation into five portions, two of which be¬ coming united, leave four and occasionally three portions, an upper, a middle, and a lower. These portions, indeed, are so long in consolidating, that they are often separate in the adult. The first is the largest, and resembles a di¬ minutive vertebra without hole, and with truncated or un¬ developed processes. A lateral portion on each side pro¬ jects like a wing, the rudiments of the transverse pro¬ cesses ; and the two tubercles above noticed, rising like An horns, are imperfect articular processes, meeting those of^ the os sacrum. The bony ridge which descends from-111 these are imperfect spinal plates; and as these do not meet, they leave between them a groove corresponding to the anterior half of the vertebral hole; and the spinous processes are wanting. In the second coccygeal bone, which is rounder than the first, the aliform portions cor¬ responding to the transverse processes are also smaller than in the first; and in the third and fourth they are diminished so much that they are scarcely cognizable. Tin pi The series of bones now described form by their union what is called the backbone, chine, spine {spina dorsi), orgei. vertebral column. Viewed in connection, it may be dis¬ tinguished into an anterior and a posterior region, two late¬ ral surfaces, a base, and an apex. The anterior region is large in the neck, narrow in the back, and broad in the loins and pelvis. A series of trans¬ verse grooves of variable depth marks the bodies of the vertebrae ; and a series of transverse elevated ridges dis¬ tinguishes in like manner their upper and lower margins. These grooves, which in the cervical vertebrae are confined to the front, extend in the dorsal and lumbar to the sides. This anterior region is covered by the anterior vertebral ligament. On the sides it answers in the neck to the ante¬ rior or great recti, and the longi colli muscles ; in the chest to the latter, to the vena azygos on the right, and the thoracic aorta on the left; in the abdomen to the abdo¬ minal aorta and the inferior cava; and in the pelvis to the rectum. In the posterior region are seen, on the mesial plane, the row of spinous processes, horizontal above and below, and imbricated in the middle. The intervals, which are con¬ siderable in the neck and loins, are much contracted in the back, in which extension brings the processes in con¬ tact. The apices of all are in general in the same straight line; but this may be disturbed, either from the wrong direction of a process, or an unnatural position of a vertebra. On each side are seen the intervertebral grooves {fissura interspinales), which commence at the occipital bone, and are continued with those of the sacrum. Broad and hori¬ zontal above, smaller and more oblique in the middle, very narrow below, these grooves are formed by the series of spinal plates, between which are left spaces varying in size according to the obliquity of the plates. These spaces are occupied within by the yellow ligaments, which being inserted at their inner surface, are something broader than the spaces, and without by the transversus spina muscle. On each side also is recognised a longitudinal hollow, extending from the atlas to the lower end of the sacrum. This hollow, which is formed by the spinous processes and the transverse processes with the spinal plates below, is superficial at the neck, narrow and deep in the back, and narrow and superficial at the loins and sacrum. In this longitudinal groove is lodged the muscle named multifidus spince. (Plate XXV. fig. 1.) The lateral regions present first the row of transverse processes, which vary in direction in different regions,^ chiefly in consequence of the spinal curvatures. Thus, it a vertical plane pass down along the sides of the column, the transverse processes of the neck and loins will be an¬ terior to it, while those of the back will be behind it. In the first region these processes are distinguished for form¬ ing, by the series of holes in the base of each, a bony canal traversed by the vertebral artery, and which is com- i illy ANATOMY. 763 j pleted in the intertransverse spaces by the intertransver- ny. sales colli. To these transverse processes numerous ^muscles are attached. Between them in the neck, and ne- anterior to them in the back and loins, is a series of holes formed by the union of the vertebral notches. Through these, which are the intervertebral holes {foramina inter- vertebralia), and which increase in size from the neck to the loins, where they are considerable, the anterior branches of the spinal nerves pass. Their shape is ellip¬ tical and their transit short. Anterior to these processes in the dorsal vertebrae are the depressed facettes, in which, with those of the fibro-cartilages, the heads of the ribs are lodged. The base of this column, which is supposed to be the last lumbar vertebra, is articulated with the sacrum in such a manner as to form an anterior convexity and a cavity behind. The base, however, may with greater justice be placed in the upper half of the sacrum, which, being firmly wedged between the thick posterior margins of the iliac bones, transmits to them, and thereby to the bones of the pelvic extremities, the weight of the trunk. The mechanism of this is similar to that of the keystone of an arch, which the sacrum truly represents. The perpen¬ dicular pressure on this bone is counteracted and balanced by the lateral pressure of the iliac bones ; and this lateral pressure is sustained, partly by their mutual pressure on each other before at the pubis, but chiefly by the oblique pressure of the neck of the thigh-bone, and the perpen¬ dicular pressure of the cylinder of the latter and those of the leg-bones. The upper extremity of the column, which is formed by the atlas and axis, receives the weight of the scull and its contents, which are exactly balanced on the articular cavities of the former bone. On this also the head is bent or extended by its proper muscles. Rotation is per¬ formed by the motion of the atlas with the head on the articular cavities of the second vertebra, and round its odontoid process. The holes of each vertebra form, by union, the verte¬ bral canal, in which are lodged the spinal chord, the origins of its nerves, and its membranous coverings. This canal, which is continuous with the cavity of the scull by means of the occipital hole above, and is completed by the sacral canal below, is not in the centre of the spine, nor is every¬ where of the same dimensions. Situate behind the vertebral bodies, and before the spinal plates, it is nearer the posterior than the anterior region of the column. Large at the neck and upper part of the back, it di¬ minishes below, and again enlarges in the loins. Its area is triangular in the cervical region, oval in the dorsal, and triangular again in the lumbar and sacral regions. It fol¬ lows the different curvatures of the spinal column. In the rece%t state, it is formed not by the bones only, but be¬ fore by the intervertebral cartilages, and behind by the yellow ligaments and the interspinales and intertransver- sales muscles. Lined by periosteum, by the posterior vertebral ligament, and by a quantity of loose cellular tis¬ sue, it is further covered by a cylindrical fibrous mem¬ brane, similar to the dura mater, the outer investment of the spinal chord; and within this are contained the liga- mentum denticulatum, the spinal arachnoid, and the spinal chord itself, with its anterior and posterior nervous roots on each side, and its appropriate blood-vessels. In early life the soft parts predominate; and the canal and its component bones are then susceptible of much freer and more extensive motion than afterwards, when ossification is complete, and the fibro-cartilages acquire firmness. In the human subject it may be viewed as a firm but flexible bony cylinder, which performs several functions at once. Resting on the sacrum, which is wedged im- Special movably between the iliac bones, it supports the trunk in Anatomy, the erect position, and transfers to the sacrum, on which it rests, the weight of the head, the chest, and great part116 sPine' of the abdomen. In the vertebrated animals in general it incloses the spinal chord, one of the most essential and constant parts of the nervous system. In the several re¬ gions it forms a sort of posterior protecting wall to seve¬ ral important vital organs. Thus, in the neck it forms a posterior barrier to the oesophagus, the windpipe, and the great sympathetic. In the back it constitutes the poste¬ rior wall of the chest; and in the loins and pelvis it is the posterior wall of the abdominal viscera and the large vessels. In answering these ends, it is important to remark, that the firmness and mechanical arrangement of the spinous processes are of essential service. Their imbricated ar¬ rangement renders it impossible for any foreign body to enter the vertebral cavity and injure the spinal chord, unless between the occipital bone and atlas, or between the atlas and axis; and even at these points much preci¬ sion is requisite to enter the cavity. Between the axis and the third vertebra it is more difficult, and below this next to impossible, without breaking the spinous processes. With this character of security and support, the verte¬ bral column unites a high degree of flexibility. _ Though the degree of motion between each vertebra is trifling, yet # between several it is considerable, and between the whole twenty-four it is multiplied to a great amount. The motions of which the vertebral articulations admit are those of flexion and extension, rotation, and lateral flexion. Of these, flexion is that which is most extensive; for in the anterior direction there is less impediment to the motion of the vertebrae than behind, where the spinous processes allow no great extent of motion, unless where the habit has been acquired in early life, before ossification is completed. The rotatory motion of one vertebra on another is small; but by combining the motion of several or of the whole column, it becomes so extensive that some individuals can turn the head and neck more than half round. That these motions are the passive result chiefly of the inter¬ vertebral cartilages and the articulations of the oblique processes, may be inferred from the fact, that when the former are ossified, or the latter ankylosed, the motions are much impaired generally, and wholly destroyed in the vertebrae affected. The motions of the head on the atlas have been already shortly noticed. Those of the atlas and occipital bone on the axis are, though simple in effect, complex in me¬ chanism. The motion, indeed, is limited to that of lota- tion; but this rotation is extensive. This is favoured by the horizontal position, and the large extent of the infe¬ rior articular processes of the atlas, and the superior ones of the axis, the looseness of the articular capsule, and the absence of spinous process in the atlas. The axis and its odontoid process becoming the fixed point, the atlas, and with it the occipital bone and scull, turn on the ellipii- cal flat articular surfaces, and on the odontoid process. On the first they glide extensively, and in opposite direc¬ tions, while the capsular ligaments are stretched. On the odontoid process the motion is more limited, and ironi right to left, and conversely; and in the latter variety ot motion, the arch of the atlas before, and the transverse ligament behind, move on the anterior and posterior fa¬ cettes of the odontoid process. _ ... . The anatomical construction of this articulation, how¬ ever, which is so favourable to extensive motion, is at¬ tended with the disadvantage of facilitating the luxation of the atlas on the axis. Luxation, indeed, may be re- /o4 ANATOMY. Special gardetl as produced by too extensive motion of these Anatomy, bones, in which the articular processes of the former ver- tebra abandon those of the latter, and instead of resting I he spine. on are p]aced on the same plane, while the spinous processes are separated at least half an inch. It may be further observed, that the want of fibro-cartilages between these bones before, and of yellow ligaments behind, is favourable to displacement. The effect of this change of position on the spinal chord is" obvious. While the one side of the atlas is thrust off the axis, the other is forced so near its body and articular process, that it compresses the spinal chord, and may occasion palsy or immediate death, by injuring the chord above the origins of the phrenic and intercostal nerves. The vertebral arteries at the same time undergo so much stretching, that the blood cannot move through them with the natural facility. It is nevertheless probable that displacement rarely oc¬ curs without such injury to the ligaments as to allow more extensive luxation than that now noticed. The odon¬ toid ligaments, or the transverse, may be ruptured; and in either case the odontoid process is allowed to slip backwards, and plunges into the chord, and destroys its texture almost instantly. These ligaments may be rup¬ tured either immediately by sudden violence, or in conse¬ quence of previous disease. In such circumstances, the injury done to the spinal chord is followed by almost im- , mediate death, in consequence of the influence of the phrenic and intercostal nerves being suddenly suspended. In the same manner, the insertion of a cutting instrument between the occipital bone and atlas, or between the lat¬ ter and the axis, so as to divide partially or completely the spinal chord above the origin of these nerves, an ope¬ ration known by the name of pithing, is followed by im¬ mediate death. § 2. The Chest. (Pectus, Sr^og, Thorax.) The chest may be defined as an osteo-cartilaginous in¬ closure, of an irregular conoidal shape, flattened before, concave behind, and convex on the sides. Its upper ex¬ tremity is truncated. Its basis is irregularly oblique. It consists of the sternum before, the twelve dorsal vertebrcc behind, twelve ribs on each side, and twelve cartilages connecting the ribs and sternum. The ster- The sternum (sternum, aregvov, os pectoris) is a symmetri- num or cal, oblong, flattened bone, broad above, narrow in the breast- middle, broad below, and terminating in a point placed perpendicularly on the anterior of the chest. It presents two surfaces, an anterior and posterior, two extremities, an upper and lower, and two margins. (Plate XXIV. fig. 1.) The anterior or cutaneous surface, covered by skin, the aponeurosis of the sterno-mastoid and large pectoral muscles,and periosteum, is marked by four transverse ridges at intervals of an inch, indicating the lines at which the separate portions of the bone were united. The posterior, internal, or mediastinal surface, is a little concave, occa¬ sionally marked by a longitudinal depression in its mid¬ dle; also presents transverse lines, but rather indistinct; is covered in the middle by the mediastinal cellular tis¬ sue, above by the sterno-hyoid and sterno-thyroid mus¬ cles, and on the sides by the triangulares sterni. The superior or clavicular extremity of the sternum presents three crescentic sinuosities; one on the middle, bounded on each side by an elevated peak, hollowed be¬ fore and behind, and one on each side, incrusted with cartilage and synovial membrane. The first of these cor¬ responds with the trachea on the inside, and has the sterno-mastoid muscle inserted on each outside. With the two lateral cartilaginous surfaces the sternal extremi¬ ties of the clavicles are articulated. Between the two is bone. the interclavicular ligament, and all round are the liga- Spe i mentous fibres of the sterno-clavicular articulation. This Anat v. upper extremity is about double the breadth of the bone^^ J at its middle. Below, the bone becomes narrow, and be- s w. low the fourth ridge it seldom exceeds half an inch in breadth. Here it terminates in an appendage, which is generally named the pointed or ensiform cartilage (carti- lago mucronata, c. ensiformis). The shape of this is by no means always the same. In some subjects it is a flat, thin, and pointed process, not always very firm, but more solid than cartilage ; in others it is a flat thin bone, terminat¬ ing in two thin hooked points. In some it is obtuse and perforated. In some it is thrust forwards, in others it is bent inwards, or towards the one side. To this process the aponeuroses of the recti abdominis are attached. The margins of the sternum, which are generally about half an inch thick, present seven articular depressions crust¬ ed by cartilage. The first of these, in which the sternal extremity of the first rib is lodged, is, immediately below the clavicular depression, superficial and rounded. The others, which are situate at the ends of the transverse ridges, and receive the cartilages of the next six ribs, are deeper, angular, and surrounded by elevated margins, to which, in the recent state, the circumference of a capsular ligament is attached. In general, the seventh depression is formed partly on the sternum, partly on the ensiform cartilage; and the intervals between the depressions are smaller below than above. The sternum is chiefly cancellated, light, and loose, with little density, and a thin crust of compact bone. In the foetus and infant it consists of eight or nine square pieces, separated by transverse furrows, which, by the union of two, are easily reduced to seven, and afterwards to five. By the further union of two of these portions they are afterwards reduced to three; and in this state they re¬ main so long in some subjects that Soemmering describes the sternum not as one bone, but as three. The first of these portions, which is uppermost, is irregularly heart- shaped, or rather octagonal, with the tracheal depression and the clavicular articulations above, the depression for the cartilage of the first rib on the side, and half of that for the second at its lower margin, where it unites with the second. The latter is merely the middle and longest portion of the bone, and is occasionally in three portions, sepa¬ rated at the costal depressions. The third or lower por¬ tion is the ensiform cartilage, the ossification of which renders the bone complete. The ribs may be defined to be long, flat, irregular 1C bones, with an irregular semicircular curvature, placed on each side of the chest, at intervals of an inch or less, be¬ tween the dorsal vertebrae and the sternum. In general their number is twelve on each side, rarely eleven of thirteen. Of these, seven are connected with the sternum before by individual cartilages, and five are connected in¬ directly to the cartilage of the seventh, without attach¬ ment to the sternum. The former are denominated true or sterno-vertebral ribs (costce verce) ; the latter are styled false or vertebral (costce spurice, vel nothce). Each rib varies in length, breadth, and the direction of its curvature. The upper ribs are the shortest, and most incurvated in proportion to their length. The middle ribs, or the fourth, fifth, sixth, and seventh, are the longest, and form curves of the largest circle. The false ribs, which diminish in length from the eighth to the twelfth, are the least incurvated, or form curves of the largest circle. It is chiefly from the middle set that the common characters of these bones should be derived. Proceeding on this principle, we find that each rib ma) be defined as a broad, flat, longitudinal bone, not only in- ANATOMY. 765 Spexl curvated, but twisted from the direction of its original Anawy- curvature. Each rib has a vertebral extremity, a cartila- ginous extremity, and a body. The vertebral extremity Theps. consists of a tuberculated angular head {caput), with two cartilaginous facettes united at an angular line for inser¬ tion in the intervertebral depressions with which they are articulated. In the first and twelfth, and sometimes in the eleventh, there is one facette only corresponding to the single vertebra with which these bones are connected. Immediately before the head the rib is contracted and rounded, so as to form a neck {collum), which varies from five to six or seven lines in length; and before the neck is a tubercle or process {tuberculum) divided into two por¬ tions, one internal, smooth, cartilaginous, and uneven, ar¬ ticulated with the transverse processes of the dorsal ver¬ tebra? ; the other external, rough, giving attachment to the middle costo-transverse ligament. Anterior to the tubercle the rib is straight for about one inch, and rough by the insertion of the sacrolumbalis and longissimus dorsi muscles. Beyond this point, which is therefore named the angle {angulus), the rib begins to be incurvated cir¬ cularly, and bent downwards, so that the surfaces, which were external and internal, become obliquely superior and inferior. To prevent confusion, however, they must still be .distinguished in the same manner. The outer surface of the rib, therefore, is convex, and forms the outer bend of the circle. Behind, it is covered by the latissimus dorsi muscle. The internal, which forms the inner bend of the circle, is convex above, and forms a concave hollow below, bounded by two sharp margins ; one proceeding straight from the head forwards, till it is lost about three inches from the cartilaginous ex¬ tremity ; the other, more acute, from the tubercle, and following the curvature of the rib to about two inches from the same point. In this groove are lodged the in¬ tercostal artery, vein, and nerve. The internal intercos- tals are attached to the inner lip of the margin; the exter¬ nal to the outer. The upper margin of the rib is obtuse behind, where the external intercostals are inserted; but becomes acute and rough before, where the internal in¬ tercostals are inserted. The anterior or sternal extremi¬ ty of the rib is broad and large, and terminates in an oval hollow, in which the cartilage is inserted. In advanced life, when the union between the rib and cartilage is in¬ timate, this hollow becomes less distinct. Besides these common characters of the ribs, several pre¬ sent peculiarities deserving notice. The first rib is short, almost semicircular, and its direc¬ tion is such that its broad surfaces are superior and inferior, not external and internal, as in the others. The head of this rib possesses only one large articular facette, corre¬ sponding with the first dorsal vertebra, sometimes one large one, and a minute one corresponding with a small space of the last cervical vertebra. Its neck is short and round, and its tubercle is identified with the angle which is wanting. The superior surface of this rib is highly im¬ portant. From the head and tubercle extends a rough surface, in which are inserted part of the scalenus posticus, part of the serratus magnus, and the scalenus medius. Next to this is a smooth, deep depression, over which the sub¬ clavian artery passes; then is an eminence, to which the scalenus anticus is attached; afterwards a superficial hollow, in which the subclavian vein is lodged; and, lastly, a rough surface at the sternal or anterior end, for the sub¬ clavian muscle. The lower surface of the first rib is un¬ even and slightly rough, but without groove at its outer margin. The second rib resembles the first in direction, hav¬ ing rather an upper and lower, than an external and in¬ ternal surface. The head is angular and acuminated, and Specip.l the neck contracted; and the upper surface is rough by the Anatomy. serratus magnus ; but the lower surface, from the tubercle, begins to present an angle in the shape of an oblique sur- Tlie rib3, face, bounded below by a rough ridge, within which is the groove for the intercostal vessels and nerves. Ante¬ rior to this flat oblique surface the rib is twisted, and undergoes a change in direction. In the third the angle is not more distinct, and it is only in the fourth that this part is well marked. This character continues to the eleventh, when it becomes indistinct, and in which the tuberosity disappears, or at least is identified with the head, which has only one facette. The groove also is so short as scarcely to be observed. Lastly, the twelfth rib, which is often unconnected with the others by cartilage, is without tuberosity, groove, or angle, and has, like the first, only one facette at the head. The true ribs are connected to the sternum by means The costal of broad rounded pieces of cartilage, variable in length cartilages, and direction in different ribs. That of the first rib is very short, rather broad, and its direction, though oblique from above downwards, is more horizontal than that of the in¬ ferior ones. The angle at which it unites with the ster¬ num is acute above, and obtuse below. It is often ossi¬ fied in the adult. The second is nearly horizontal, and follows the direction of the rib to which it is attached. The next five are more oblique from above downwards, as the lower end of the sternum inclines forwards, and the corresponding ribs bulge towards the base of the chest. Each of these cartilages, invested by perichondrium, is attached by a rough surface to the anterior end of the rib; while the other extremity, which is rounded and covered by synovial membrane, is lodged in one of the articular depressions of the lateral margin of the sternum, and secured in this situation by a capsular ligament, strengthened by anterior and posterior fibrous bands. The anterior or outer surface of the thoracic cartilages is slightly convex, the internal or posterior surface flat, inclining to concave, lined by pleura and covered by the triangularis sterni muscle. The upper margin is concave, the lower convex, giving attachment to the internal inter¬ costal muscles, which in this region fill the intercartilagi- nous spaces. The cartilages of the five false ribs differ from those of the true, in not being articulated directly with the sternum. The cartilage of the eighth rib, after bending forwards and upwards, is attached to the seventh by a tapering point with a minute articular surface. The ninth cartilage is attached in a similar manner to the eighth, the tenth to the ninth, the eleventh to the tenth, and the twelfth is either attached in the same manner to the eleventh, or hangs free, though attached to muscles connected with the others. Hence the twelfth, and not unfrequently tlm eleventh, are denominated floating ribs. The whole of them are mutually connected by ligamentous fibres inserted into their perichondrial covering. The outer surface of these cartilages is covered by the recti and external ob¬ lique, the inner surface by the diaphragm and transversus. Connected with the ribs in the same manner in which those of the true ribs are, these cartilages differ, however, in taking a direction, first of descent, then of ascent 01 of curvature. Ihe spaces which they leave between them, instead of being rhomboidal, as those of the true ribs, are irregularly triangular. In structure the costal cartilages belong to those of the cavities. Analogous to those of the larynx, they are dense, firm, elastic, whitish substances, without distinct traces of organization, and seem to consist chiefly of modi¬ fied gelatine, to which they are with difficulty reduced by ANATOMY. 766 Special long boiling. Their tendency to ossification is consider- Anatomy. able. In few persons above 45 or 50 are they quite free from bony points; and in many they are at this period converted into firm bone. The cartilage of the first rib, especially, is often firmly ossified before 35. When they undergo this change, certain points in their substance are observed to assume an orange or tawny colour, and to ex¬ hibit a porous arrangement, with great hardness, turning the edge of the knife. By long maceration the costal cartilages become soft and gelatinous, and are finally resolved into oval patches, separated by circular or spiral lines, with numerous per¬ forations. It was perhaps on this account that Herissant described them as consisting of spiral fibres. The chest The bones and cartilages now described, with the twelve in general, dorsal vertebrae behind, constitute the bony skeleton of the chest, bearing a remote resemblance to a cone, with truncated apex and oblique base, or, more accurately, to the frustum of a cone. To form a just idea of this assem¬ blage of parts, it is necessary to consider its surface ex¬ ternal and internal, its circumference above and below, its transverse diameter, and its longitudinal extent. _ The anterior region of the external surface, consisting of the sternum in the middle, and the cartilages on each side, is flattened, contracted above, wider and more promi¬ nent below. The intercostal spaces are filled between the sternum and the ribs by the internal intercostals, behind this by the external and internal, and covered by the anterior part of the large pectoral muscle. Behind, the chest presents the vertebrae with their processes, the transverse processes articulated with the tubercles, the angles forming a line obliquely receding from the spine, the transverse grooves, the longitudinal groove on each side filled by the multifidus spince, and the space be¬ tween the processes and the angles of the ribs occupied by the spinalis dorsi, the longissimus dorsi, and the sacro- lumbalis. The intercostal spaces, from the spine to the angles, are filled by the external intercostals; and anterior to this are the two layers of muscles. The lateral regions of the chest are convex, making a larger sweep below than above. They present on each side eleven intercostal spaces, the superior of which are shorter and broader than the inferior. These spaces, which fol¬ low the curved direction of the ribs, cannot be accurately defined in shape. Between the angles and the cartilages, where the curvature is greatest, they are occupied by the double layer of the external and internal intercostal muscles, which, lying inclined in opposite directions, mu¬ tually decussate in this tract. The lateral region of the chest is covered above by the serratus magnus behind, and the two pectorals before; below by the external ob¬ lique on the side, and the recti before. The inferior lateral region, which is formed by the cartilages of the ribs, is therefore named the hypochondres {hypochondria). The inner surface of the chest is, before, correspond¬ ent to the outer surface, unless below, where the anterior inclination of the sternum makes the antero-posterior dia¬ meter greater. The posterior region is marked by the row of vertebral bodies, the prominence of which forms an imperfect partition, which separates the right and left halves of the thorax; and which, notwithstanding the posterior bend which the spine undergoes between the second and eighth vertebrae, diminishes the antero-poste¬ rior diameter of the chest. On each side is a large con¬ cave hollow, narrow above, wide below, and swelling most capaciously in the middle, the walls of which, formed by the ribs and intercostal muscles, are lined by the pleura, and the cavity of which contains the lungs. The upper circumference of the chest, or its apex, is Spe 1 small, oval, transversely oblique from above downwards, AnatL y. and from behind forwards. Bounded before by the ster-1^^ ^ num, behind by the first dorsal vertebra, and on the side by the first rib, it is diminished by the clavicles; and while its antero-posterior diameter is occupied by the wind¬ pipe, tesophagus, and the large vessels connected with the heart, its lateral portions are so much contracted, that each thoracic half (demithorax) has here almost a coni¬ cal termination. Its dimensions in the male skeleton of average size are about 16 inches. As the first rib has little or no motion, the upper circumference remains un¬ changed. The lower circumference of the chest, which is much more extensive, is said to be nearly four times larger than the upper. This, However, is exaggerated; and I find its greatest dimensions in the male to be 32 inches, exactly double the small circumference. It is suscep¬ tible of enlargement from the revolving motion of the ribs. The first rib remains fixed, while the lower ones are capable of being rolled outwards on their heads, tubercles and cartilages, so that the transverse diameter of the chest is enlarged. The lower circumference of the chest presents anteriorly a*large triangular notch (inci- sara trigona), with the apex at the ensiform cartilage, the sides at the margins of the cartilage, and the base repre¬ sented by a transverse line uniting the tips of the twelfth rib on each side. This notch, which, in the recent state, is occupied by the heads of the recti muscles, with their fasciae in the middle, and the anterior margins of the ex¬ ternal oblique at the sides, constitutes what is called the pit of the stomach {scrobiculus cordis), or the epigastric region {epigastrium). The transverse diameter of the chest is small above, but gradually enlarges to the ninth or tenth rib. The average diameter measured between the inner margins of the first ribs on each side in the male skeleton is four and a half inches; the average diameter measured between the tips of the eleventh rib on each side is nine inches, which is also nearly the diameter between the inner mar¬ gins of the fifth ribs; and the average diameter measur¬ ed across the upper margin of the ninth rib, which is about the widest part, amounts to eleven inches. These diameters, it has been already said, are susceptible of slight enlargement, by reason of the lateral revolution of the ribs ; and this motion is most extensive between the sixth and tenth ribs. Above the sixth and below the tenth it is trifling. The longitudinal extent or altitude of the chest varies; but in the same male skeleton it amounts to twelve inches measured between the lower margin of the first rib and the upper margin of the eleventh, which may be regarded as the inferior limit of the osseous part of the chest. From the top of the sternum to the plane of the ensiform cartilage the distance is five inches and a half. If from the lower margin of a mesial plane representing the medias¬ tinum, another plane be drawn on each side to the margins of the false ribs, the space inclosed on each side above this oblique plane will give some idea of the capacity of the thoracic cavities. The dimensions above stated apply chiefly to the adult male, from about thirty to thirty-five years, and of average size. In the female the chest is generally smaller in every direction, rounder, and more taper towards its inferior region. Above, as far as to the fourth rib, it is said to be larger and more uneven before, so that it has less of the conoidal shape than the male chest. It is also shorter. The pectoral cavity is in general symmetrical, that is» ANATOMY. jlpjal of similar shape and dimensions on each side of the me- Ana-ny- gial plane. Sometimes, however, without the interven- tion of disease, the greater convexity of two or three ribs on one side gives it a more ample appearance than on the other. § 3. The Pelvis. This is the name given to the irregular-shaped bony cincture which terminates the lower extremity of the trunk, and which is connected to the spinal column by means of the sacrum. It consists in the adult of four bones, two lateral portions {ossa coxarum), and two on the mesial plane, the sacrum and os coccygis. The latter two have been already described. The lateral and anterior divisions now come under examination. These consist of two bones, one on each side, united with each other before by means of fibro-cartilage, and receiving between them behind, the sacrum, to which they are in like manner united by fibro-cartilage. These bones, which are denominated ossa innominata, coxal or haunch-bones {ossa coxarum), are of a very irregular shape, and may be divided into three regions, the supe¬ rior or iliac, the anterior or_ pubal, and the inferior or ischial. These regions it is not easy to define accurately; but they will appear in the course of description, and they correspond to the original divisions of the bone in the foetal state. Thakal The coxal bone presents two surfaces, an external or femoral, and an internal or pelvic; and a circumference, divided into superior margin, anterior margin, inferior margin, and posterior margin. The external or femoral surface {dorsum), which is alter¬ nately concave and convex, presents behind a rough sur¬ face, to which the glutceus maximus is attached ; between this and a semicircular rough linea lunated hollow, in which the origin of the glutceus medius is lodged; and between the upper semicircular line and the lower a convex and con¬ cave area, for the attachment of the glutceus minimus, and one or two inequalities, to which one of the tendons of the rectusfemoris is attached. About an inch below is a large hemi-spherical cavity, with elevated circular margins, inter¬ rupted at the anterior and inferior corner, named the aceta¬ bulum,ox cotyloid cavity, for receiving the head of the thigh¬ bone. Its inner surface is covered by cartilage, unless at the centre, where is a depression for the attachment of the triangular ligament of the thigh-bone. The lower part of the margin is marked by a deep notch, over which, in the recent state, is stretched a ligament, thus forming a hole for the transit of the vessels and nerves of the articular cavity. The surface behind the acetabulum is slightly convex, indicating its union with the upper edge of apart of the coxal bone, distinguished by the name of hip¬ bone (os ischii), and may be denominated the post-acetabu- Ilar or ilio-ischial eminence ; below, it is concave and sinuous, for the tendon of the obturator externus, and terminating in a sharp spine {spina ischii), to which the small sacro-sciatic ligament is attached. Anterior to the acetabulum is a large opening, named the thyroid or obturator hole, oval in the male, and triangular in the female, closed by a ligament at¬ tached to its circumference, unless at the upper part, where there is an oblique groove forthe oie,tll,in the upper jaw. [heist- The orders of teeth now enumerated constitute arches of a parabolic or semielliptical shape, larger in general in the upper jaw than in the lower. In the upper arch especially, the curvature is more rounded or elliptical; in the lower it is more angular and parabolic,—a cir¬ cumstance which, with the different directions of the axes of the incisor and molar teeth respectively, causes the upper incisors to overlap, and thereby cut upon the lower ones, while the molars are fitted to each other so as to move on mutual surfaces in the lateral motion of die jaw. Faria'S. The teeth vary in number, shape, and position. Though the general number of the adult or perma¬ nent teeth is 16 in each jaw, or 32 in all, it may happen that, in consequence of all the wisdom-teeth not coming through the gum, there are only 28 or 30. Occasionally also the lateral incisors are wanting. In some rare in¬ stances there is a supernumerary incisor or molar tooth ; and Soemmering mentions an instance in which, by the addition of four molar teeth, the total number was aug¬ mented to 36. The union of two or more teeth into one is occasionally observed. The most usual variations in shape are observed in the incisors being excessively large and broad, in the canine being very thick and long, ascending into the antrum, and in some rare instances extremely small. In females the canine teeth are occasionally so small and rounded, that they have the appearance rather of rudiments than of perfect teeth. The cleft roots of the molar teeth are liable to very great varieties in shape. The most usual variety in position is when the inci¬ sors are placed obliquely, with their margins not lateral but antero-posterior. This is in general the result of the teeth being too much crowded in a small alveolar arch; and the malposition is always greatest as the jaw is nar¬ row, or imperfectly formed. One or two incisors even in such circumstances may be entirely behind or before the rest, so as to give the appearance of a double row. The canine teeth are liable to the same change of position; but one greatly more frequent with them is, to be placed so much before the line of the arch as to project consi¬ derably forwards, like the tusks of some animals. Ano- ther form of this variety is, when teeth appear in unusual situations, for instance the palate or pharynx, or even in the orbit. w m The teeth are not at all periods of life the same in num- “ ’ ber. Generally speaking, at birth, when the teeth have not appeared above the gum, the rudiments of five teeth are found in each half alveolar arch. These, which are to con¬ stitute the milk-teeth, the deciduous or temporary, appear above the gum nearly in the following order: the central incisors of the lower jaw about the end of the sixth or beginning of the seventh month; a few weeks after, the central incisors of the upper jaw ; after these, the lateral incisors above or below, without determinate order; and between the 12th and 18th months the first pair of molars, either above or below. These are followed by the lower canine teeth, and about the second year by the upper Canine teeth. About the end of the second year, or in the course of the third, the second pair of molar teeth cut the gum; and about the fourth or fifth year in general, the third pair of molar teeth appear. The following table of tile periods at which the different classes of temporary teeth appear, given by Mr Thomas Bell, may communi¬ cate a general idea of the succession. Special Anatomy. The teeth. From 5 to 8 months, the 4 central incisors. From 7 to 10 the 4 lateral incisors. From 12 to 16 the 4 anterior molars. From 14 to 20 the 4 canine. From 18 to 36 the 4 posterior molars. From these periods, however, there are extensive ex¬ ceptions ; and in no two individuals even of the same fa¬ mily does the same tooth appear at the same period. About the seventh month the milk-teeth begin to ap- Dentition pear above the gum; and about the seventh year theyPermaiient begin to be shed and succeeded by the permanent set. This process begins also in the lower jaw, and advances nearly in the same order: the lower central incisors; the upper, and the lateral above and below; the first pair of molar upper and lower; the second pair of molar above and below ; the canine above and below ; the third pair of molar; the fourth pair of molar in the eighteenth year; and the fifth pair, or wisdom-teeth, in the eighteenth, twentieth, or thirtieth years. The average periods of eruption in the lower jaw are given in the tabular form by Mr Thomas Bell, in the fol¬ lowing order. The anterior larger molars 6^ years. The central incisors 7 The lateral incisors 8 The anterior bicuspids 9 The posterior bicuspids 10 The canine or cuspidati 11—12 The second large molars 12—13 The third large molars, or wisdom-teeth 17—19 Those of the upper jaw are understood to follow these at an interval of two or three months. In structure the teeth of the human subject belong to the order of simple teeth, that is, consist of bone, invest¬ ed at the crown by enamel. The hyoid bone {os hyoides, v, ossa lingualid), though The hyoid entirely unconnected with the skeleton, yet as a bone to ^^lsual which are attached various muscles of the throat, must00 be noticed in this place. It is a bone, or rather a bony apparatus, consisting of five separate pieces, arranged in the parabolic form, and articulated movably with each other. These five pieces are, one middle, two lateral, and two pisiform bones. The middle {os medium linguce), named also the body, is large, broad, and square, with the anterior surface in ge¬ neral convex and rough, divided by a middle ridge into right and left halves, and by a horizontal line into upper and lower parts, and giving attachment on each side of the middle crest to the digastric, the stylo-hyoid, the mylo-hyoid, the genio-hyoid, and the hyoglossal muscles. The posterior surface is concave and smooth, and covered by cellular tissue, connecting it to the epiglottis. To its inferior margin, which is more extensive and irregular than the superior, are attached externally the sterno¬ hyoid, the omo-hyoid, and the thyro-hyoid muscles; and in the middle the thyro-hyoid membrane. To its upper margin the fibres of the hyoglossus are attached. Each of the lateral margins is moulded into a convex cartilagi¬ nous surface, articulated with the lateral bones. The lateral bones {ossa lateralia, cornua), though longer, are less thick than the body. Broad and thick before, with the upper surface concave and the lowei convex, narrow behind, they terminate in a round head, tipped with cartilage, to which the thyro-hyoid ligament is at¬ tached. At the anterior junction nearly of these with the middle portion, there is attached to the latter on each side a small elongated bone, somewhat hooked. These bones, which seldom exceed the size of a grain of wheat, or rye rather, and which they somewhat resemble in 782 ANATOM Y. Special shape, are articulated to the other two by a true capsu- Anatomy. lar ligament. To their outer surface are attached some fibres of the genio-glossus, and to their upper is fixed the stylo-hyoid ligament. The hyoid bone consists externally of compact, and in¬ ternally of cancellated tissue, the latter being most abun¬ dant in the middle piece. Though composed in the in¬ fant and young subject of five portions, the articulations are invariably obliterated by ankylosis in adult life, and they are converted into a single bone. The junction of the middle and lateral portions is effected first, and that of the pisiform bones afterwards. tures. The era- The bones now described, excepting the lower jaw and nium in hyoid, are united immovably, or by synarthrosis. The general. external shape of the cranium is that of an oblong sphe¬ roid, or an ovoid, with the small diameter before. Con¬ vex in general, it is flattened laterally in the temporal regions, and below in the base. The external surface, smooth and regular above, is marked below by muscular impressions, and penetrated by numerous holes. The su- The first objects deserving attention are the serrated lines of junction, or what are named the sutures {sutures), which are in general more conspicuous externally than in¬ ternally, where indeed they are effaced at an earlier period of life than on the outer surface of the scull. The sutures may be most easily understood by tracing them from the sphenoid bone, which may be regarded as the central point of the cranium. The first line is that which passes transversely across at the junction of the sphenoid with the ethmoid and su¬ perior turbinated bones in the middle, and the frontal bone on each side. Concave in the middle, this line bends backward at each extremity, where it follows the outline of the small wings of Ingrassias. It constitutes the trans¬ verse or sphenoidal suture. The posterior margin of the body of the sphenoid bone is marked by another transverse suture, extremely short, and uniting it with the cuneiform process of the occipital bone. This, which is early obliterated by the indissoluble union of the sphenoid and occipital bones, is a cartilagi¬ nous junction, afterwards ossified, and, though scarcely en¬ titled to the epithet, is named nevertheless the basilar suture. A more distinct one is found in the line between the exterior concave margin of the large wing of Ingrassias and the squamous portion of the temporal bone in the spheno-temporal suture. It terminates below at the gle¬ noid fissure, forming an acute angle with a short line between the pyramid and the posterior margin of the spinous process of the sphenoid, named the petro-sphe- noidal. Above, where it terminates on the parietal bone, a short line, between the outer margin of the large wing of Ingrassias and short spaces of the parietal and frontal bones, is distinguished as the lateral sphenoidal or the spheno-parietal suture. This line, produced backwards between the upper margin of the temporal and the lower margin of the pa¬ rietal bone, constitutes a peculiar form of junction, named the squamous suture {sutura squamosa), the temporal, or the temporo-parietal, in which the edge of the former bone is imbricated over that of the latter. In this mode of junc¬ tion, which is confined to the superior part of the tem¬ poral bone, and in which the union of the bones is not se¬ cured by dove-tail ossification, but simple imposition, the lateral pressure is effected chiefly by the force propagat¬ ed from the zygoma and the malar bone. The posterior part, which is united to the posterior- inferior angle of the parietal, and the anterior-inferior margin of the occipital, presents a serrated line, with al- Sj| ternate indentations, which are well marked, but irregu- Anl lar in size. This, which occasionally presents Wormian ^ bones, may be named the posterior-temporal suture. The^i descending portion has been distinguished by the name ofin t mastoid suture. Anteriorly, in the base of the cranium, where it passes the jugular notch, the line of junction, which is cartilaginous, is termed, the petro-occipital suture. The sutures now enumerated agree in being found chiefly at the lower region of the cranium, and in secur¬ ing the junctions of its base. The others to be yet enu¬ merated belong to its superior region, and agree in con¬ solidating and securing the several arches which consti¬ tute what may be named the vault of the cranium. From the point at which the posterior, temporal, and mastoid sutures unite, a serrated line of junction ascends on each side to the common point at which the occipital and parietal bones meet. From the angular junction formed by the two limbs of this suture, it is known under the name of lambdoidal (A, sutura lambdoidalis); and from its situation it is termed the occipital and occipito-pa- rietal suture. By mutual indentations, which are always distinct, it joins firmly the parietal and occipital bones; and it is the most frequent seat of Wormian bones. From the angle of the lambdoidal suture a similar ser¬ rated line proceeds, uniting the two parietal bones on the mesial plane, with equally distinct indentations. The mode in which this stretches between the lambdoidal and coronal sutures, bearing some remote resemblance to an arrow on the drawn bow-string, has procured it the name of the sagittal {sutura sagittalis). In youth and in early life these two sutures are distinct; but in advanced age they are more or less, sometimes entirely, obliterated. In some craniums the sagittal suture is continued along the frontal bone to the nasal spine, thus parting the bone in two lateral halves. This, which constitutes the proper frontal or median suture, is the remains of the original se¬ paration of the bone. Lastly, Between the frontal bone before, and the parie¬ tal bones behind, is seen a serrated line crossing the cra¬ nium transversely, the whole breadth between the two sphenoid bones. This, which is named the coronal suture, presents large indentations on each side and small ones in the middle, on the external table, and a converse ar¬ rangement on the internal. By these sutures the bones forming the vault of the cranium are firmly secured; and each bone is made to press against the other so as to augment rather than di¬ minish strength. The external surface of the cranium may be distin-Thej guished into four regions, a superior, an inferior, and twonalspci lateral ones. The superior region, or the vault, is bounded before and behind by the nasal and occipital protuberances, and on each side by the temporal arches. It presents, besides the coronal, sagittal, and lambdoidal sutures, the superci¬ liary arches, the frontal, parietal, and occipital protube¬ rances, and the parietal holes. It is covered by the epi¬ cranial muscle and its aponeurosis. The inferior region or base, which may be defined from the occipital protuberance behind to the nasal spine be¬ fore, is free as far as the pterygoid processes of the sphe¬ noid bone, anterior to which it is joined to the bones of the face. In the posterior portion are seen the occipital spine and muscular impressions, the occipital hole {foramen mag¬ num), the condyloid processes, the anterior and posterior condyloid holes, and the basilar process. Laterally are the digastric groove, the mastoid, styloid, and vaginal pro- ter ANATOMY. S j:ial cesses, and the stylo-mastoid hole, the glenoid cavity and fissure; the jugular hole {foramen lacerum in basi cranii), Vseparated by a bony process into an internal part for the nervus vagus and the accessory nerve, and an external for ' the jugular vein; the pyramid, with the carotic canal, and the anterior lacerated hole between its extremity, the basilar process, and the sphenoid bone, closed by fibro- cartilage in the recent subject. Before these objects, and nearly in the same transverse line, are seen the ante¬ rior half of the glenoid cavity of the temporal bone, the guttural orifice of the Eustachian tube, the spinous and J elliptical holes of the sphenoid (Plate XXIV. fig. 5), and the pterj'goid processes. • The anterior portion presents the crest or azygos pro¬ cess united with the vomer and ethmoidal plate, the sphenoidal- sinuses, the ethmoidal bone itself, and the nasal spine of the frontal bone ; laterally, the anterior sur¬ face of the pterygoid processes, the Vidian canal, the round or superior maxillary hole, the temporal and orbitar surfaces of the large wings of the sphenoid bone, the sphe¬ noidal fissure {foramen lacerum), the optic holes, and the small wings of Ingrassias; and, lastly, the vault and inter¬ nal wall of the orbit, the former by the frontal bone, the latter by the os planum and lacrymal bone. The lateral regions of the cranium are nearly of an el¬ liptical shape. Each region may be circumscribed by a line drawn from the mastoid process backwards to the union of the temporal and mastoid sutures, then following the semicircular arch of the parietal bone, and the angu¬ lar arch of the frontal to the zygoma, ear-hole, and mastoid process. The objects inclosed in this region are the pos¬ terior mastoid hole, the mastoid process, the ear-hole, and the zygoma, with a large space, defined by the ele¬ vated line extending from the posterior extremity of the zygoma upwards to the semicircular arch of the pa¬ rietal bone, where it is obtuse, and the external angu¬ lar ridge of the frontal bone, where it becomes acute. To this line, the zygoma, and the malar bone, the fascia of the temporal muscle is firmly attached; the muscular fibres adhere to the bone below as far as the line of the sphenoid bone, and pass downwards under the zygoma. The whole region, though convex in early life, becomes less so in adolescence, and in manhood and advanced age it is flattened and even hollowed. ■ yer. The internal surface of the cranium, lined by the dura mater, and marked by cerebral and vascular impressions, is distinguished into the superior region or vault, and the inferior or base. In the former, which is a regular spheroidal concave, the chief peculiarities are, on the mesial plane, the frontal crest, the sagittal groove for the superior longitudinal sinus, pits for the granules of Pacchioni, and the inside of the sagittal suture,, more distinct than the outside; laterally, the upper cerebral regions of the frontal and parietal bones, with their fossce, the coronal suture, and the superior occipital fossae. The base is more complicated, and is generally distin¬ guished not only into lateral halves, but into anterior, middle, and posterior regions. On the median line from before backwards, the objects arej—the blind hole {foramen caecum), for the naso-frontal vessels; the ethmoidal crest {crista galli), and vertical plate, with the perforated plate (e); the spheno-ethmoi- dal suture ; the transverse groove and olivary process, and optic holes (11); the pituitary fossa {ephippium) (3) ; the posterior clinoid processes (4 4) ; the spheno-oc- cipital junction ; the basilar groove for the medulla ob- knigata (6); the occipital hole; and the internal occi¬ pital spine and protuberance. (Plate XXIV. fig. 6.) 783 m a# Of the lateral halves, the anterior or frontal region is Special bounded beroie by an indistinct curved line, formed by Anatomy, the vertical with the horizontal table of the frontal bone, and behind by the sphenoidal arch. In this, which ispranium named the frontal fossa, the anterior lobe of the brainm Seneral- is lodged; while the sphenoidal arch enters the fissure of Sylvius. Between the sphenoidal arch before, and the posterior margin of the temporal pyramid behind, is contained a cavity shaped like a spherical segment. In this, which may be named the spheno-temporal hollow {fossa spheno- temporalis), the anterior part of the posterior lobe of the brain is lodged. In this cavity also are seen the sphe¬ noidal fissure ; the round or superior maxillary hole ; the oval or inferior maxillary hole; the spinous or meningeal hole, with the meningeal groove; the anterior or spheno- temporal fissure {foramen lacerum anterius basis cranii) ; the inner end of the carotic canal; the pyramidal groove ; and the semilunar fossa for the Gasserian ganglion. (Plate XXIV. fig. 6.) Between the temporal pyramid and the internal occipi¬ tal spine is contained the posterior or temporo-occipital hollow {fossa temporo-occipitalis), which is further subdi¬ vided into two cavities, the cerebral above, and the cere- bellic below. From the posterior margin of the pyramid to the transverse occipital ridge, a fold of the dura mater, stretched horizontally, separates the temporo-occipital ca¬ vity into a superior for lodging the posterior lobe of the brain, and an inferior or cerebellic for lodging the lobes of the cerebellum. In the anterior or cerebellic division is seen the posterior surface of the pyramid, with the inter¬ nal auditory hole, the orifice of the cochlear aqueduct, the groove for the lateral sinus terminating in the jugular opening, the groove of the inferior petrous sinus, and the mastoid hole and suture. The only object behind is the posterior cerebral/ossa, traversed by the lambdoidal suture. In the foetus the cranial bones inclosed between theDevelope- pericranium and dura mater, which are thick, soft, and ment and vascular, are incomplete shells not in contact with each dimensions other, with prominent and rather thick ossific centres, from which the osseous radii diverge, and terminate in thin,penoc b' ciliated margins. At birth, and for some weeks after, though ossification is far advanced, the margins of the bones are incomplete, so as to form the open spaces denominated fon- tanelles. Of these there are six at the period of birth ; the anterior or rhomboidal between the frontal and parietal bones; the posterior or triangular between the occipi¬ tal and parietal bones; two lateral anterior between the parietal, sphenoidal, and temporal bones; and two pos¬ terior lateral between the parietal, temporal, and occipital bones, both of irregular shape. At these points the mo¬ tions of the brain are distinctly felt. At the same time the bones have not yet acquired their serrated margins, so that the places of the sutures, which are not yet formed, are occupied by narrow grooves between the cranial bones. As ossification advances, how¬ ever, their fimbriated margins extend, and mutually meet¬ ing, are prolonged so as to be indented into each other by alternate notches and processes. At the same time the bones acquire thickness, so that a distinct space is perceived between the external and internal surface of each. The alternate processes and notches thus acquire firmness, and are immovably dovetailed into each other. In this manner the anterior angles of the parietal bones unite with the frontal, and between the posterior ones the apex of the occipital bone is gradually mortised. In some instances, however, where the ossific centre of the original bone appears deficient in energy, or tardy in progress, a new centre may be developed in the line of 784 A N A T Special junction, while the bones are still much apart. Thus, be- Anatomy. tween the occipital and parietal bones, or between the oc- cipital and temporal bones, maybe developed new cen- Cranium tres? frorn which ossification advances, as from the prin- m gener . cjpa| p0jntSj towards the circumference; and by the suc¬ cessive deposition of bony matter, the margins begin to meet those of the primary bones. The process of mutual indentation takes place exactly in the same manner as with the primary bones; and by this means secondary bones are formed in the lines of the sutures. The period at which the cranium is entirely ossified varies in different individuals. In general the anterior or fronto-parietal fontanelle, which is the largest, is ossified at the end of the 18th or 20th month, while the anterior and posterior lateral are closed at an earlier period. In some instances, however, between the parietal and frontal bones a small space is left till the 6th or 7th year; and in many persons the part continues depressed and tender for the greater part of life. The sutures are completed at the same time, and are always distinctly formed by the 10th or 11th year. A few years after, they become more consolidated, and, as the bones acquire thickness and den¬ sity by the compactness of the external and internal tables, are firmly wedged into each other. The spheno- basilar junction generally remains soft and separable till adult age, when by its union the sphenoid and occipital bones are converted into a single piece. Some time after¬ wards the sphenoid is united with the ethmoid, the two parietals are converted into one, and occasionally one or both are united to the frontal bone. In advanced age many of the sutures disappear entirely, at least in one surface of the cranium, generally the internal first; and the cra¬ nium would be converted into a single bone if life were continued sufficiently long. In shape and dimensions the cranium varies at different periods of life. After ossification is completed in the child, the prominence of the ossific points, which continue more or less conspicuous till manhood and the formation of the frontal sinuses, gives it a cubo-spheroidal shape. Its section is an oval or two hemispheroidal segments, the anterior being the smallest. At this period the parietal tuberosities and the occipital eminence are prominent, the frontal bone is vaulted, and the high open fore¬ head communicates to the countenance an expression of beauty and simplicity which are always associated with the early and middle periods of life. In the progress of years, however, these prominences become less distinct, partly by the operation of muscular action, partly by the uniform rising and swelling of the margins of all the bones ; and the anterior upper and posterior part acquires a uni¬ form spheroidal or vaulted appearance, while the lateral regions are flattened by the action of the temporal muscle. The occipital region also below the spine is flattened, and occasionally excavated; so that while the spine is prominent and unciform, the base is excavated, and overhung by the mastoid processes and the semilunar ridges. The aged scull is thus distinguished by a general rotundity or ovoi- dal character, unless in the temples, which are flat and hol¬ low ; and the convex but occasionally depressed forehead indicates in some degree the transition from youth to age. The dimensions of the cranium are estimated from its diameters, longitudinal, transverse, and vertical. The first, which extends from the foramen caecum of the frontal bone, is about five inches at an average. The largest transverse diameter, which extends between the bases of the temporal pyramids, is about 4*i inches; and a smaller one between the extremities of the two small sphenoidal wings is about 3 inches and 9 lines. The longest vertical diameter, which is between the anterior margin of the O M Y. occipital hole and the middle of the sagittal suture, varies Spcii from 4 inches to 4 inches and 3 lines. From these mea- Anal surements it results, that the most capacious part of the scull is nearly at the union of the two anterior thirds with Pran the posterior, viz. the level of the occipital hole and basi¬ lar groove; and that the ovoidal or oblong-spheroidal is the most general shape. The variations from this shape are found chiefly in the vault, which may be flattened, ob¬ long, cuboidal, or conical. The Asio-European maybe regarded as the best and Varies, most symmetrical shape, and to this most of the European crania belong. According to Soemmering, the Belgic scull is the most oblong-globular, the German and Italian sphe¬ rical, and the Turkish the most spherical of the Euro¬ pean. In this country the most usual shape is the oblong- spheroidal, especially among the inhabitants of England. Among an extensive collection of sculls preserved in the Museum of the University of Edinburgh, and believed to be chiefly Parisian, the prevalent shape is the oblong-sphe¬ roidal, and the globular, or the general spherical shape, with large transverse diameter approaching to the longitudinal From the delineations given by Sandifort {Museum Am- tomicum, tom. ii.), the English appears most prominent in the occipital region, the French the most vertical forehead, and the Italian most elevated in the vertical region, and most prominent between the parietal tuberosities. The scull of the Swede approaches the cubo-spheroidal, and that of the Russ is distinguished chiefly for the verti¬ cal front, considerable transverse width, and large cheek¬ bones. The latter appear not to be peculiar to the Scotish cranium. Of the Asiatic craniums, the Tartar has the forehead large, not much arched, the occipital region large, the nasal bones descending straight from the frontal, the upper maxillary bone slightly overhanging the lower, and the chin prominent. That of the Calmuc has the vertical, occipital, and parietal regions prominent, the frontal bone and face flattened, the cheek-bones large, and the alveolar arches and jaws broad and prominent. The Mongolian is distinguished by the narrow forehead, flattened and ra¬ ther depressed glabellar and nasal regions, great facial width between the cheek-bones, and prominent upper jaw. From the observations of Blumenbach and Soemmering it results, that the ancient Egyptian or Coptic head, as ex¬ emplified in mummies,belongs to the European class of cra¬ niums. The negro head, on the contrary, is distinguished for its oblique forehead, compressed sides, prominent jaws, general wedged shape, and large size compared with the rest of the skeleton. For more minute information on these varieties, the reader will consult with advantage the work of Soemmering (tom. i.), and the Decades Craniorum of Blumenbach. In shape the face forms an irregular hexahedron, with The j’t' a large excavation at its lower region for the mouth andgea ?• pharynx. Its anterior surface is trapezoidal, with the short side below; its sides trapezoidal, with the short side formed by the posterior margin of the maxillary ramus ; and its upper surface is an oblique parallelogram. The greatest transverse diameter is between the zygo¬ matic angles of the cheek-bones, varying from 4J to 5 inches; its smallest at the symphysis of the lower jaw, from 1^ to 2 or 2A inches; and on the extent and promi¬ nence of which depends the general oval shape of the countenance. The height, measured from the glabella to the triangular process of the lower jaw, varies from 42 to 4 inches 9 lines. The direction of the face varies according to the posi¬ tion of the lower jaw. When this is horizontal, the facial plane forms with it an angle of 60°, or deviates 30° from ANATOMY. 785 gpeo the vertical plane; and in some tribes, as the negro, this pitcip deviation is still greater. A more important character, however, is believed to be found by determining the direc- ra® tion of the face in relation to that of the cranium, or ascer- |8en,l‘ taining what Camper denominates the facial angle. This he proposes to fix by drawing one line from the fronto¬ nasal protuberance to the spine of the upper maxillary bone,—the facial (linea facialis) •, another transversely be¬ tween the external ear-holes; and from the latter a third line {linea, horizontalis), drawn at right angles to meet the first. The angle thus formed by the facial and horizontal lines, which is termed the facial, indicates the compara¬ tive prominence of the cranium and face. In European heads generally it is about 80°; in the negro it is not above 70°; and in the Mongolian, which is intermediate, it is about 75°. The effect of this angle in giving the countenance intellectual expression, the nearer it ap¬ proaches to the rectangle, was known to the ancients. In many of the busts of heroes it is almost 90°, and in those of divinities 100° ; and as we know that this is much more rectangular than any specimen of the human scull fur¬ nishes, it may be inferred that it is imaginary. It may be further observed, that in the infant the fa¬ cial angle approaches to 90°, in consequence of the small relative developement of the face. Towards boyhood and puberty, when the face acquires greater size and promi¬ nence, it diminishes to 85° aqd 80° successively. (Cu¬ vier, Bichat.) The face is subdivided into cranial, facial, zygomatic, and palato-maxillary regions. It is unnecessary to enu¬ merate again the objects found in these several regions; but it is requisite to consider shortly the cavities which are formed by the cranio-facial bones. They consist of the nasal cavities, the orbits, the tympanal cavity, and the palato-maxillary region. These cavities are distin¬ guished by the following circumstances. All of them com¬ municate mutually, and are covered by fibro-mucous mem¬ brane, also continuous. In each of them is lodged one of the organs of special sensation; and each communicates with the cranial cavity by openings, through which nerves always, and sometimes vessels, are transmitted. Lastly, these cavities may be regarded as the points by which the cutaneous surface communicates directly with the mucous membrane of the gastro-puhnonary organs. The nasal cavities {cavum nasale, nares), of an irregular quadrilateral shape, consist of four regions; the upper, the lower, and two lateral. The first is bounded before by the nasal bones, behind by the sphenoidal cells, with which it communicates, and above by the cribriform plate ; while its lower limit is a line uniting the inferior margins of the lateral portions of the ethmoid bone. This is parted by the vertical plate of the ethmoid bone into two halves, which are the two superior passages {meatus superior). The lower region is bounded below by the pa¬ lato-maxillary plate; on the sides by the maxillary, palate, and inferior turbinated bones; above by a plane uniting the lower margins of these bones, and is parted into two by the vomer, which opens before at the nasal notch of the maxillary bones, and behind at the posterior margin of the palate bones. This constitutes the lower passage {meatus inferior), at the anterior extremity of which the nasal canal opens. The anterior part of the region pre¬ sents on the mesial plane a vertical triangular notch be¬ tween the middle ethmoid plate above and the vomer below, occupied in the recent subject by the cartilaginous septum of the nose. The middle and lateral regions, which com¬ municate before by this notch, are separated behind by the ethmoid plate and vomer, and are bounded above by the ethmoidal turbinated bone, and below by the maxillary VOL. II. turbinated bone. This constitutes the middle canal {men- Special tus medius), in which the frontal and maxillary sinuses open. Anatomy. These cavities communicate freely with each other; and their parietes are covered by continuations of the?ramum same general fibro-mucous membrane. Their use appears111 Senerab to be to increase the extent without adding to the weight of the facial bones, to afford great superficial extent to the nasal membrane as an organ of smell, and to afford a so¬ norous vault to the organ of voice. These cavities, and their appendages, do not exist in the foetus, nor for some time after birth. The ethmoidal and sphenoidal are early formed; and the maxillary sinus begins to be manifest some months after birth. After the primary dentition they enlarge, and rapidly after the se¬ cond ; and towards the approach of puberty, when the maxillary tuberosity is formed, they increase, and speedily attain their natural capacity. The orbits are two cavities, one on each side of the me¬ sial plane, of the shape of a quadrilateral pyramid, with the apex towards the cranial cavity, and the base ante¬ riorly. Each orbit presents a vault formed by the fron¬ tal bone, a floor formed by the superior maxillary, an internal wall formed by the palate bone, ethmoid, and lacrymal, and an external wall formed by the malar and sphenoid bones. The two internal walls are nearly pa¬ rallel,—an arrangement which renders the axes of the or¬ bits convergent backwards, and indefinitely divergent be¬ fore. The vault of the orbit is so thin, that a pointed instrument easily penetrates; and a thrust in the eye is invariably attended with severe, generally fatal, in¬ jury to the base of the brain. The base of the orbits is oblique, with the temporal margin behind the plane of the nasal, making the eye more exposed without than on the mesial side. The inner or nasal margin presents the up¬ per orifice of the nasal canal. At the posterior extremity of the inner wall is the optic hole; at the apex is the sphenoidal fissure, which forms nearly a right angle with the spheno-maxillary fissure below; and the floor is tra¬ versed by the superior maxillary fissure and canal. The apex of the orbit is occupied by the optic nerve, the third and fourth pair, the ophthalmic branch of the fifth, and the sixth; and the origins of the six muscles of the eyeball, with interposed fat. The base is occupied by the eyeball, surrounded with the tendinous extremities of the muscles, the lacrymal gland at the external region of the vault, and the lacrymal sac in the anterior depression of the nasal margin. To its margins are attached the palpebral and the orbicular muscle. Each orbit communicates with the nasal cavities by means of the nasal duct. The tympanal cavity, formed in the temporal bone, com¬ municates by the Eustachian tube with the posterior part of the nasal and palato-maxillary cavities. Its further examination belongs to a subsequent head. The palato-maxillary cavity is formed by the palatine vault above, the alveolar arches and teeth before, by the lower jaw before and laterally, and behind by the basilar process of the occipital bone and the pterygoid processes. It is very irregular in shape, and consists ot two regions, the palato-maxillary proper and the pharyngeal. Ihe principal objects deserving notice are the incisive duct in the palatine vault, for the naso-palatine nerves ; the ptery- go-palatine canal at its posterior angles, for the pterygo¬ palatine branches; and the posterior opening of the nasal cavities. The vault is covered by periosteum and mucous membrane, with the uvula or soft palate suspended at its posterior margin; and the space inclosed by the lower jaw contains the tongue, attached to the hyoid bone, sublin¬ gual and submaxillary glands, and is completed by mem¬ brane, muscles, and integuments. O G 786 ANATOMY. Special Anatomy. The sea. pula. § 6. The Thoracic Extremities. The superior or thoracic extremities consist of the shoulder, the arm, the fore-arm, the wrist, and the hand. The shoulder consists of two bones,—the scapula or shoulder-blade, and the clavicle or collar-bone. ’ The scapula is a triangular bone occupying the posterior part of the chest, having a dorsal and a costal surface, and a superior, a vertebral, and an axillary margin. The dorsal or posterior surface {dorsum) is divided by a transverse elevated spine into two parts, \he fossa supra- spinata for the supraspinatus muscle, and the fossa infra- spinata for the infraspinatus muscle. The latter is con¬ cave above, convex in the middle, and concave towards the axillary or external margin {costa), from which it is se¬ parated by a round line or crest for the attachment of the fascia which separates the infraspinatus from the teres major and minor. Between this crest and the axillary margin above is a convex surface, of a triangular shape, with the apex above, for the attachment of the teres mi¬ nor, and below a flat quadrilateral surface for the teres major. The spine is a triangular-shaped eminence, rising obliquely from the upper fourth of the dorsal surface ; low at the vertebral, elevated at the axillary margin, where it terminates in a broad, flat surface, also triangular, named the acromion or shoulder-top. In the posterior margin of the spine may generally be distinguished two surfaces separated by a ridge. Above the ridge the cucullaris is fixed; below, part of the deltoid is attached; and be¬ tween is a common aponeurosis. The ridge is hiparted towards the acromion, leaving an interval covered by pe¬ riosteum and integuments only. The anterior part of the acromion presents a cartilaginous facette, for articulation with the acromial end of the clavicle. To its posterior and external margin the deltoid is attached, and to its tip the acromio-coracoid ligament is fixed. The costal or anterior surface is of a triangular shape, with the apex below, generally concave, but subdivided into smaller spaces by two or more oblique ridges, to which intermuscular fascice are attached. This surface, which is the subscapidar fossa {venter), lodges the belly of the subscapular muscle, the fasciculi of which are inter¬ posed between the aponeurotic ridges. Near the verte¬ bral margin is an irregular surface, to which, and also to the margin, the serratus magnus is attached. The superior margin {costa superior) is thin and point¬ ed behind, where the levator and omohyoid muscles are attached, and becomes sinuous externally, with a notch converted by a ligament into a hole for the transit of the suprascapular vessels and nerves. The inner or axillary extremity terminates in an elevated hooked process, the coracoid, to the tip of which are fixed the coraco-clavicu- lar ligament, and the united origin of the short head of the biceps flexor and the coraco-brachialis, to the anterior margin the small pectoral, and to the posterior the acro¬ mio-coracoid ligament. The vertebral or posterior margin {costa posterior, basis of some authors) is thin, and ascends straight to the spine, giving attachment to the rhomboideus ; then bends forward, and forms with the superior an angle, to which, as also to the edge now mentioned, the levator is fixed. The axillary margin {costa axillaris, sometimes inferior) is round and broad above, and narrow below. It presents above, first the glenoid cavity, round at its lower margin, angular above, hollow, covered by cartilage and synovial membrane for receiving the head of the humerus. At the angular point above is a surface for the attachment of the long head of the biceps flexor, and the lower margin presents two tubercular eminences for that of the skj long head of the triceps extensor. Below this are fixed the A no mi teres minor, the subscapularis, and the teres major. The pvt i tissimus dorsi, passing over its lower angle, binds it down. The scapula consists chiefly of compact bone, with^g little cancellated matter interposed. In the subscapular fossa this becomes completely absorbed, rendering the bone thin and translucent, sometimes perforated. The spine, processes, and angles contain cancellated matter. It is formed from one part for the body of the bone, with epiphyses for the coracoid process and the margins. Nutritious holes are generally found in the angle formed by the spine with the body, and in the axillary margin. The collar bone or clavicle is a cylindrical bone, alter-Clave nately incurvated like an f placed at the upper part of thec°k chest, between the sternum and acromion of the scapula. It has therefore two extremities, a sternal and acromial, with intermediate body. The sternal end is triangular, cartilaginous, concave and convex in opposite directions, surrounded by ligamentous insertions. The acromial end is flattened and recurved, presenting a lunated surface for articulation with the acromion. The body, with the shape of a triangular prism at the sternal end, is rounded above for the attachment of the cla¬ vicular portion of the sterno-mastoid muscle, and presents below a rough surface for the costo-clavicular ligament, and a sinuated line for the subclavian muscle. Towards the acromial end, where it is flattened above and below, it presents before, a surface for the attachment of the large pectoral and deltoid muscles; behind, another for the cucullaris; and below, a prominent oblique crest for the coraco-clavicular ligaments. Compact in the middle, and cancellated at its extremi¬ ties, the clavicle is developed from a single point. The arm-bone or humerus {os brachii) is a long cylin- '• *1C drical bone, divided into head or scapular’ end, cubital or x,1‘l lower end, and shaft or body. The head presents three eminences, the articular head, the anterior tuberosity, and the external tuberosity. The first, which is hemispherical, incrusted by cartilage and sy¬ novial membrane, with the axis oblique to that of the bone, and articulating with the glenoid cavity of the sca¬ pula, is separated from the bone by a narrow depressed line named the neck {collum), in which is fixed the margin of the scapulo-humeral capsular ligament. The second is a small, pointed, sometimes bifid eminence, to which the tendon of the subscapularis is attached. In the external tuberosity are distinguished three facettes, to the upper of which the tendon of the supraspinatus, to the middle that of the infra¬ spinatus, and to the posterior the tendon of the teres minor, are inserted. Betwreen the anterior and the external tube¬ rosity is a longitudinal groove named the bicipital, for the transit of the long head of the biceps flexor. The cubital or lower extremity is flattened transversely, and moulded into different eminences and depressions. Internally is the inner or ulnar condyle, large and pro¬ minent, for the attachment of the internal lateral liga¬ ment, and a tendon common to the pronator teres, pahnans longus, flexor sublimis, radialis internus, and ulnaris inter- Externally is the outer or radial condyle, to which are attached the external lateral ligament, and the ten¬ don common to the supinators and extensors, viz. supina¬ tor longus and brevis, anconeus, radialis externus, ulnans externus, and extensor communis. Between these is an articular surface covered by cartilage, moulded into the small head which moves in the cavity of the radius,—f groove corresponding to the margin of the latter; the semicircular crestinterposed between the radius snAulna,— rSHial /<> lli-. >ic [tipi- ps] ANATOMY. 787 another groove rather larger, in which the prominence of the fibro-cartilage of the joint; and behind and without Special the sigmoid cavity is ^lodged ; and the trochlear or pulley- the styloid process is a longitudinal groove for the motion Anatomy. y like eminence, which is received in the internal part of the sigmoid cavity, and the size of which renders the inner side of the humerus larger than the outer, and gives it the ob¬ lique direction when placed on the horizontal plane. Be¬ fore is a superficial pit for the coronoid process of the ulna during flexion of the fore-arm, and behind is a deep one for receiving the olecranon during extension. The shaft is not cylindrical, but prismatic, consisting of three surfaces, bounded by an equal number of lines. The first line, which descends from the anterior tuberosity, and, winding to the side, terminates on the ulnar condyle, is anterior above, where the tendons of the latissimus dorsi and teres major, and the short head of the triceps, are at¬ tached, but becomes internal-lateral below, where an in¬ termuscular aponeurosis is fixed. The second, which de¬ scends from the fore-part of the large tuberosity to the anterior articular pit, is anterior throughout, and gives at¬ tachment above to the large pectoral muscle, at the mid¬ dle to the deltoid, and below to the brachialis externus. The third line, which descends from the back of the great tuberosity to the external or radial condyle, is posterior above, where the triceps is fixed, but external below, where the intermuscular aponeurosis and the supinator longus are attached. Of the three surfaces, the first, which is anterior and in¬ ternal, presents above, the bicipital groove, covered by pe¬ riosteum and synovial membrane for the long head of the biceps; in the middle, the medullary hole and insertion of the coraco-brachialis ; and below, a surface covered by part of the brachialis internus. The second, which is external, is covered above by the deltoid, below by the rest of the brachialis, and in the middle presents the deltoid tube¬ rosity for the insertion of its tendon, and below this an oblique sinuosity traversed by the radial nerve. The third, which is posterior, gives attachment above to the triceps, and below is merely covered by that muscle. The humerus, cancellated at its extremities, and com¬ pact in the shaft, is ossified in three parts; one for the latter, and one for each of the former. The ulna or cubit (cubitus) is a long bone placed at the inside of the fore-arm, articulated above with the humerus, below with the carpus or wrist, and laterally with the radius. Its superior or humeral extremity consists of two eminences, and an intermediate semilunar or crescentic cavity. The first is a large head named the olecranon (uXevris xoum, ulnce caput, or elbow; processus anconeus, anxon) ; irregular above, with a small space behind, where the tendon of the triceps extensor is fixed; concave and cartilaginous before, where it forms part of the sigmoid cavity. The second is a broad, thin-edged process, prominent before, about half an inch below the olecra¬ non, the upper surface of which is cartilaginous, and completes the sigmoid cavity; the lower surface is rough for the brachialis internus, some fibres of tXxepronator teres, the jlexor sublimis, and the internal ligament of the hu- mero-cubital articulation. At the outside, and continuous with the sigmoid cavity, is a small semicircular cartila¬ ginous surface—the small semilunar—for articulating with the head of the radius. The lower or carpal extremity presents a cartilaginous surface, shaped like a circular sector, the circular margin being bent upwards, so as to form a circular surface for the inner articular surface of the radius, while from the centre of its radii arises a pointed process named the sty¬ loid, to the tip of which the external ligament of the ra¬ dio-carpal articulation is fixed. Between the styloid pro¬ cess and sectorial surface is a depression, to which is fixed of the tendon of the ulnaris externus. The shaft has the shape of a trilateral prism, except at the lower extremity, where it becomes cylindrical. Of^161111" the three lines by which the surfaces are bounded, the ieS’ external or radial, which is strongly marked, and sharp at the middle, extends from the posterior tip of the small sigmoid cavity to about two inches above the lower end, and gives attachment to the interosseous ligament. The second, internal or ulnar, which is obtuse, descends from the inner edge of the coronoid process to the inside of the styloid, and gives attachment above and in the middle to the flexor profundus, and below to the pronator quadratus. The third, posterior, obtuse above and below, sharp in the middle, extends from the olecranon to the outside of the styloid process, and gives attachment to an aponeurosis. Of the surfaces inclosed by these lines, to the anterior, which is concave, and contains the medullary hole, the flexor sublimis is attached above, and the pronator quadra¬ tus below. The inner is covered above, where it is broad, by (he flexor profundus, and below by the integuments. The posterior or radial is parted by a line into two spaces, to the larger of which are fixed the anconeus and ulnaris externus, and to the smaller the supinator brevis, extensores pollicis longus et brevis, the abductor pollicis, and extensor indicis. The radius is a long bone, rather shorter than the uhui, The ra- forming the outer bone of the fore-arm, articulated above dius. with the humerus, below with the carpus, and at the in¬ side with the ulna. The upper extremity consists of a circular cartilaginous head, concave for receiving the small head of the humerus, with a cartilaginous surface on its inner or ulnar side for articulating with the small sigmoid cavity of the ulna, and a rough one for the annular ligament on the outside. Be¬ low this the bone is contracted and forms the neck of the radius, and again swells before into a large rough promi¬ nent tubercle, to which the tendon of the biceps flexor is fixed, and which is therefore named the bicipital tube¬ rosity. The lower extremity, which is double the size, forms an extensive surface for articulation with the scaphoid and semilunar bones of the carpus, continuous on the ulnar side with a small cartilaginous surface for articulation with that of the ulna, bounded without by the styloid process, a rough triangular eminence, to which is fixed the exter¬ nal ligament, and bounded elsewhere by a rough margin for ligamentous insertions. The posterior part of this end presents two eminences inclosing a wide hollow, separat¬ ed by a small eminence into two grooves,—an inner or ulnar, large for the tendons of the extensor communis and the extensor proprius indicis, and an outer or radial tor the extensor longus pollicis. Between the middle eminence and the styloid process are two other grooves,—the an¬ terior for the abductor magnus and the extensor brevis of the thumb, and the posterior for those of the radiales externi. The shaft or body, which is thin and round above, prismatic in the middle and below, presents three surfaces inclosed by an equal number of lines. Of the latter, the inner or ulnar descends from the inner margin of the bicipital tuberosity, sharp and prominent, to the small inner articular surface, and gives attachment to the inter¬ osseous ligament. To the outer, which descends from the outer margin of the tuberosity, obtuse, to the base of the styloid process, the flexor sublimis, pronator quad¬ ratus, and supinator longus are attached. The third, also obtuse, is indistinct to the second third of the bone. 788 ANATOMY. Special whence it proceeds to the middle tubercle of the carpal Anatomy. ^ extremity. The anterior surface, which is hollow above, presents the medullary hole and the attachment of the flexor longus pollicis below that of the pronator quadratus. The posterior, hollowed in the middle, corresponds to the supinator brevis, the extensors, and abductor pollicis, which are attached to it; and the common extensors, extensor proprius indicis, and extensor pollicis, by which it is sim¬ ply covered. The external surface, which is rounded, is covered above by the supinator brevis, in the middle by the pronator teres, which are attached to it; and below by the radial extensors (radiates externi), which merely glide over it. The ulna and radius consist of cancellated structure in the epiphyses, and compact inclosing cancelli in the diaphyses, and are each ossified in three points. These two bones are mutually connected by a broad web of periosteum continued from that of the bones, and named the interosseous ligament, the principal use of which is to enable the radius to roll laterally in the mo¬ tions of pronation and supination on the idna, and to give attachment to muscles without adding to the weight of the fore-arm by intermediate bone. bones. The bones of the hand consist of those of the carpus, the metacarpus, and the phalanges. The carpal The carpus consists of eight short and irregular-shaped bones, arranged in two rows. Those of the first are the scaphoid or navicular (os scaphoides, os naviculare), the semilunar (os lunatmn), the cuneiform or trilateral (os triquetrum), and the pisiform or lenticular (os arbiculare, os pisifor me). Those of the second row are the trapezal (trapezium), the trapezoidal (os trapezoides), the large bone (os magnum, os capitatum), and the unciform bone (os unciforme, os hamatum). Of these bones, which it would be tedious to describe minutely, it is enough to say, that their names are intend¬ ed to indicate their shape; that they are connected mu¬ tually by cartilaginous surfaces, so as to allow the gliding motion only; and that, besides periosteum, they are in¬ vested by ligaments which maintain them in their posi¬ tion, and tend to strengthen and consolidate the wrist, as the basis of support for the hand and fingers. By the upper articular surface of the scaphoid and semilunar bones, the carpus is connected to the lower extremity of the radius; while the upper surface of the trilateral bone is contiguous to the fibro-cartilage of the radio-carpal articulation, and the upper surface of which is in contact with the lower articular surface of the ulna. The pisiform bone, which is attached to the anterior sur¬ face of the latter, and thus projects before the plane of the other bones into the hand, may be regarded as a sesamoid bone, which serves as a point of insertion to the tendons of the flexor carpi ulnaris above, the fibres of the adductor of the little finger below, and those of the anterior carpal ligament before. The inferior surface of the navicular bone is articulat¬ ed at once to the superior surfaces of the trapezium and trapezoides. The palmar or anterior surface of the for¬ mer presents a small groove, in which moves the tendon of the flexor carpi radialis, bounded on the outside by the pyramidal process, to which the annular ligament is at¬ tached. The os magnum, which is articulated above with the semilunar bone, on the radial side with the scaphoid and trapezoidal, below with two metacarpal bones, and on the ulnar side with the unciform bone, is thus wedged firmly like a central base between the others, and contri¬ butes much to the solidity of the carpal articulations. The unciform, which is placed at the inside of the range, and Spin] is articulated above with the lunar and cuneiform, later- Ani n ally with the scaphoid, and below with the two inner me-^l' tacarpal bones, is distinguished by the unciform processTho ic rising from its palmar surface, to which part of the abduc- [^‘if' tor and flexor brevis minimi digiti and the annular liga ment are attached, and which, stretched between this and the pyramidal process of the trapezium, form a species of arch over the flexor tendons. The carpal bones consist of cancellated tissue, invested by a thin pellicle of compact bone. In the foetus and in¬ fant they are composed chiefly of brown-coloured, callous substance, homogeneous, but without the smallest trace of bone. Their penetration with this substance takes place about eighteen months or two years after birth. The metacarpus is usually said to consist of five bones. The This is correct so far as situation goes; but one of thesecarPE bears little resemblance either in shape, connection, ort)one purpose with the other four. It appears, therefore, more natural to restrict the name of metacarpal to the four bones which support the digital phalanges, than to extend it to the thumb, the first bone of which is to be regarded as phalanx only. The four metacarpal bones agree in having trapezoidal heads, cylindrical bodies with an elevated longitudinal line before, and rounded convex lower ends for moving on the concave articular surfaces of the phalanges. Besides the upper trapezoidal surfaces for articulating with the trapezoidal, large, and unciform bones, the lateral margins are provided with facettes, the first and fourth on one side only, the mutual, the second and third, on both, for articulation with each other. In this manner the me¬ tacarpal bone of the index finger is articulated above to the trapezoidal and large bone, and on the inside to the metacarpal bone of the middle finger; the latter is arti¬ culated above to the large bone, and on the one side to the index metacarpal bone, on the other to that of the ring finger; while the latter and the metacarpal bone of the little finger are articulated above to the unciform bone and to each other. The bodies of the metacarpal bones are slightly incur- vated before, and form a hollow which corresponds with the palm. In their intervals are contained the interossei muscles, the internal at the volar, the external at the dorsal surface. The anterior surface is covered by the flexor tendons, the lumbricales, and the palmar fascia. The dorsal surface, which is convex in general, is covered by the extensor tendons. The index metacarpal bone has attached to its radial margin the first dorsal interosseus, to its ulnar, before, the first palmar interosseus, and behind the second dorsal in,' terosseus; while to its upper anterior extremity the radicdis internus is inserted, and to the same extremity behind the extensor radialis longior. To the second or middle metacarpal bone, besides the pdmax fascia and the second and third interossei, the ad¬ ductor polticis and. flexor brevis are attached to the palmar surface ; and the extensor radialis brevior is inserted into its dorsal surface. The fourth or small metacarpal bone, besides the pal¬ mar fascia and the third palmar and fourth dorsal interos- seus, gives insertion by its dorsal surface to the extensor carpi ulnaris. . The phalanges or bones of the fingers are fifteen small longitudinal bones placed vertically on each other, three to each finger; or forming ranges distinguished into meta¬ carpal, middle, and unguinal, the first row being the long¬ est, the second shorter, and the third or unguinal the shortest. ANATOMY. tool The metacarpal phalanges agree in having the upper inatiiy- extremities shaped like rounded cubes, with concave car- tilaginous surfaces for receiving the lower extremities of tel?1' the metacarpal bones, and tubercular sides for the attach- I1^: ment of the lateral ligaments. The upper ends of the middle and unguinal are moulded into two cartilaginous cavities with an intermediate ridge, with lateral tubercles for the lateral ligaments. The lower extremities of the me¬ tacarpal and middle phalanges^ which are smaller than the upper, are rounded and separated by a small groove into two condyles, which are received into the cavities of the up¬ per ends. The lower extremities of the unguinal phalanges, which terminate the fingers, are flattened antero-posterior- ly, and moulded into crescentic tips (lunulce) transversely. The bodies of the metacarpal and middle phalanges are convex behind, and have a surface flat before, bounded on each side by a sharp marginal line, and taper gradually from above downwards. Those of the unguinal phalanges, except¬ ing that of the thumb, are convex before as well as behind. The palmar surface of the metacarpal phalanges is covered by the flexor tendons, which in the superficial muscle are inserted into the anterior and upper part of the middle phalanx, while those of the deep-seated flexor are inserted into the upper anterior part of the unguinal phalanx. The first phalanx of the thumb, which is generally considered as a metacarpal bone, has the abductor magnus inserted into its upper extremity, and the opponens suuS. flexor brevis into its body. The dorsal surfaces are covered by the ex¬ tensor tendons, which, with those of the lumbricales and interossei, are inserted into the middle phalanges. The metacarpal and phalangeal bones are compact, with cancellated extremities, and are ossified in three points. or The bones now enumerated are connected so as to ad- ,ons mit of motion to various extents. The humerus, articulat- ;:|!j r’ ed with the glenoid cavity of the scapula by a capsular ligament, while the long head of the biceps serves the purpose of a round ligament, admits of motion in every direction,—flexion, extension, abduction, adduction, cir- Iho cumduction, and rotation. The humero-cubital articulation, * which is secured by two lateral ligaments, admits of ex¬ tension and flexion only; but in any position of the ulna in relation to the humerus, the radius rolls on the former, so as to produce those motions of the wrist and hand which are denominated pronation or internal rotation, and supi¬ nation or external rotation. lr's id The carpal bones are articulated chiefly with the radius, ? so as to admit of flexion and extension, adduction and ab¬ duction, and even some degree of circumduction and ro¬ tation. The metacarpal bones are limited in motion. The metacarpal phalanges admit of flexion and extension, ab¬ duction and adduction, circumduction and rotation ; while those of the middle and unguinal range are confined to flexion and extension. The precision, nevertheless, ot which these motions are susceptible, with the numerous modifications which they undergo in combination with the opposable powers of the thumb, and the nicety and deli¬ cacy of tact inherent in the skin of the fingers, are the means from which the human hand derives its remarkable aptitude for all the mechanical arts, and all operations requiring manual dexterity. By the combination almost endless of a number of simple motions, so many complex motions are produced, that it is difficult to set limits to the degree of perfection which the hand and fingers, as an organ of prehension, may attain. ^OS S 7. The Bones of the Pelvic Extremities. ■the+l.' 3 - The bones proper to the lower or pelvic extremities e are, the thigh-bone {femur), the shin-bone {tibia), and 789 leg-bone {fibula); with the knee-pan {rotula,patella), seven Special tarsal bones, four metatarsal bones, and 15 phalanges. Anatomy. The thigh-bone (femur, osfemoris) is the largest, thick- est, strongest, and heaviest bone of the skeleton. The thiSh- The upper or iliac extremity consists of a head, neck,bone' and two tuberosities named trochanters. The head is globular, incrusted by cartilage and synovial membrane, unless at its internal point, where there is an irregular de¬ pression for the insertion of the round ligament, and is lodged in the cotyloid cavity (acetabulum). It is situate internally in relation to the shaft; and its axis, which forms with that of the latter an obtuse angle, variable in extent according to age and sex, is represented by that of the neck, a contracted cylinder of bone, varying in length ac¬ cording to the same circumstances, flattened before and behind, presenting numerous vascular holes, and covered by fibrous slips and synovial membrane. The junction of the neck with the bone is marked by a large prominent body named the trochanter major (x), in which four surfaces may be recognised ; an external lateral, for the insertion of the glutceus medius, and the motion of the tendon of the glutceus maximus; an internal with a pit, for the in¬ sertion of the tendon of the pyriformis, of the gemelli, and of the obturators; an anterior for the insertion of the ten¬ don of the glutceus minimus ; and a posterior for that of the quadratus femoris. At the union of the neck with the diaphysis below, and externally, is a conical eminence named the small trochanter (t), to which the united tendon of the psoas magnus and iliacus internus is fixed. The spaces between the trochanters before and behind are united by oblique rough lines, to which the femoral margin of the capsular ligament is attached, and the entire space within which is continuous with the articular cavity. The lower or tibial extremity, which is large, is moulded into two rounded eminences named condyles f-MvbuXoi) (1, 2; a, b); the one internal, deeper, and larger than the external, separated by an antero-posterior depres¬ sion (fossa intercondylaris), and prominent and convex behind. Each condyle has an external and internal sur¬ face, while the articular one, which is incrusted by carti¬ lage and synovial membrane, is shaped something like a horse-shoe, incurvated upwards in the middle before, and behind on each side, with elevated irregular margins for the attachment of the articular capsule. The intercondylar depression before receives the upper part of the knee-pan (patella), while in the intercondylar cavity behind are lodged the fimbriated margins of the synovial membrane, with the femoral ends of the cross ligaments, the anterior of which is inserted into the inner surface of the external condyle, and the posterior into that of the internal con¬ dyle. The outer or fibular surface of the external condyle presents an eminence for the attachment ot the external lateral ligament, and a depression below for that of the poplitceus. The outer or tibial surface of the internal condyle has a prominent tubercle, to which are fixed the internal lateral ligament and the tendon of the adductor magnus. In a pit above each condyle the heads of the gemellus (gastrocnemius externus) are fixed. The shaft or body, which approaches the cylindrical shape, is incurvated, with the convexity before, and the concavity behind (F, f). The anterior surface is uni¬ formly round, and covered by the crurceus, which is fixed above to the interval between the trochanters. The pos¬ terior surface presents a rough elevated line, descend¬ ing from the base of the large trochanter, meeting a simi¬ lar line descending from the small trochanter, and in¬ closing a triangular rough space, forming about the middle third of the bone a rough elevated line (lima aspera) (1), which again is parted into two, less distinct; one termi- 790 ANATOMY.

To the upper part of the external line, where it is most prominent, the tendon of the glutceus maximus is inserted ; next is the short head of the biceps ; and to the rest are fixed the fibres of the vastus externus. To the inner line the pectinceus and adductor brevis are inserted above, and the vastus internus is attached below; while the adductor longus and magnus are fixed to its whole length, unless at one point, where it is interrupted about three inches above the condyle by a smooth sur¬ face, on which the femoral artery passes under the tendon of the adductor magnus, to continue its course between the condyles, where it becomes the popliteal artery. The femur, which is one of the most perfect examples of a long cylindrical bone, is compact in the diaphysis, with distinct medullary canal, and cancellated in the epi¬ physes. It is ossified in four portions; one for the dia- v physis and neck, one for the two condyles, one for the head, and in general one for the trochanter major. The neck, which is short in early life, becomes long in adult age, and the body acquires its peculiar incurvation appa¬ rently from muscular action. In the female this incurva¬ tion is greater than in the male, and the neck forms a greater angle with the body. The knee- The knee-pan (rotula,patella) (p) is a short bone, shaped Pan- like a heart, with the apex downward, convex and fibrous before, where it is covered by tendinous matter; flat above, where the rectus, the two vasti, and the crurceus, are inserted; plane and concave behind, where it is covered by cartilage and synovial membrane, and separated into two unequal divisions by a middle ridge, forming the an¬ terior wall of the knee-joint, and applied by its superior half over the anterior intercondylar fossa. The lower apex is rough for the attachment of the inferior ligament; and to the margins are fixed those of the fibro-tendinous capsular, by which it is connected to the femur and tibia. The knee-pan, which has a peculiar cancellated struc¬ ture, invested by a thin plate of compact bone, is to be regarded partly as a sesamoid bone for the insertion of the common tendon of the four extensors of the leg, partly as an appendage or epiphysis to the superior part of the tibia, performing to that bone the same function which the olecranon does to the ulna. The shin- The tibia is a prismatic-shaped long bone, situate at the bone. inner and anterior region of the leg, with the femoral condyles above, the astragalus below, and the Jibida on the external side. The head, upper or femoral end, is large., and of an ir¬ regular oval shape. It presents two slightly concave elliptical cartilaginous surfaces, with the long diameter antero-posterior, separated by a rough vascular space, large before and narrow behind. Of these elliptical sur¬ faces the external margin is most regular, and presents a crescentic or lunated mark for the attachment of the semi¬ lunar fibro-cartilages, which thus increase the concavity of the articular surfaces for the reception of the condyles. The inner or mesial margin of each is elevated into a curved peak, mutually separated by a depression. These eminences, which are jointly named the spine of the tibia, correspond in flexion and extension to the intercondylar fossa. Before is a triarcual surface, rough for the insertion of the anterior crucial ligament, and behind a notch for that of the posterior. The lateral circumference of the head, which is rough, and marked by vascular holes, pre¬ sents before a triangular surface, the upper half of which corresponds to the inner surface of the knee-pan, and is ■ contained within the cavity of the joint; while the lower angular portion is convex for the insertion of the inferior patellar ligament, or the last insertion of the tendon of the rectus and vastus externus. The sides, which are rounded Sj ia and prominent, are named respectively the external and in- An; m ternal tuberosities, and give attachment to the external and'^H > internal lateral ligaments. To the back part of the inter¬ nal also the tendon of the semimembranosus is fixed (d), while that of the external presents a cartilaginous facette for the articulation of the head of the fibula (c). The lower or tarsal extremity, which is much smaller, is nearly quadrilateral, with a cartilaginous surface con¬ cave transversely, with elevated anterior and posterior borders, and the internal raised into a vertical eminence named the inner ankle {malleolus internus') (f), to the apex of which the internal lateral ligament is fixed. This carti¬ laginous surface, which receives the head of the astragalus, is surrounded by a furrow, very distinct before, in which ligamentous fibres are inserted; while the external margin, which is broader than the internal, presents between two prominences a trilateral hollow, in which the tarsal end of the fibula is lodged. The anterior surface is covered by the tendons of the tibialis anticus and extensor pro- prius hallucis; and the posterior, behind the internal ankle, is marked by a groove for the tibialis posticus and flexor longus digitorum, and another for the flexor longus hallucis. The body or diaphysis, which is thick above, is prisma¬ tic, and presents three surfaces, bounded by the same number of lines. The first, which is anterior {crista), descends sharp and prominent from the anterior margin of the external tuberosity to the fore part of the internal ankle, and, though subcutaneous, gives attachment to the tibial aponeurosis and the tibialis anticus. To the ex¬ ternal, which is sharp, and descends from the posterior margin of the same tuberosity to the anterior tubercle of the lower end, the interosseous ligament is fixed. To the internal, which is obtuse, and rather rounded, and descends from the posterior part of the internal tuberosity to that of the inner ankle, the poplitceus above, and the second or inner head of the solceus, with the flexor longus digitorum, are attached. The surfaces bounded by these lines are intenml, ex¬ ternal, and posterior. The first, which is convex, gives insertion above to the sartorius, gracilis, and semitendi- nosus, and is elsewhere covered by integuments only. The external is concave above, where the tibialis anticus is fixed; convex below, where it is covered by the tendons of this muscle, and of the extensor communis and proprim. The posterior is crossed by an oblique line (T, 1, Plate XXV.) descending from the fibular articular surface to the internal line, and forming two spaces, the superior of which, triangular, is covered by the poplitceus inserted into the oblique line, while the lower, occupied by the tibialis posticus and flexor longus, presents also the medul¬ lary holes. The tibia, compact in the diaphysis, with medullary canal, cancellated in the epiphyses, is ossified in three por¬ tions, one for the former part, and one for each of the latter. The fibula, which is the most slender bone of the skele-The ton of equal length, is situate at the outer side of the^one‘ tibia, with its lower extremity anterior to the plane of the upper, articulated above with the latter bone only, below with the tibia and astragalus at once. The head or tibial end, which is of an irregular cuboi- dal shape, presents above an oblique, trilateral, cartilagi¬ nous surface, articulated with that behind the external tibial tuberosity, by which also it is overhung. Before is a triangular surface, slightly convex, for part of the femo- ro-tibial ligament; behind, a tubercular surface for liga¬ mentous insertions; and externally, between the two, is an extensive pentagonal surface for the insertion of the ANATOMY. ! filial bicipital tendon, terniinating above in an angular point, to P which is fixed the peroneo-tibial ligament. The lower or tarsal end consists of a pointed trilateral pyramid, the external surface of which, somewhat convex, is subcutaneous, and forms the external or fibular ankle {malleolus externus) (e). Within is a trapezoidal cartilagi¬ nous surface, which is articulated with the astragalus; and behind and below is a rough triangular surface, with a cavi¬ ty for the insertion of the fibulo-tarsal ligament, while the external ligament is fixed to its angular tip. The poste¬ rior surface presents a groove, sometimes two, incrusted by fibro-cartilage for the motion of the peroncei longus et brevis. The body is marked by several lines inclosing sur¬ faces rather irregular in shape and extent. Among the former the following may be recognised :—An anterior, commencing about 21 inches below the head, distinct in the middle, where the aponeurosis common to the exten¬ sor longus digitorum and peronceus tertius before, and the peronceus longus et brevis behind, is attached, and bifur¬ cating about 21 inches above the lower end into an ante¬ rior and posterior, terminating on the anterior and posterior margins respectively of the malleolus externus, inclosing a triangular space, which is covered by integuments only. The internal, descending from about an inch below the head to the anterior edge of the internal malleolus, coin¬ cides there with the anterior part of the anterior line. To this, above and in the middle, the tibialis posticus and flexor proprius pollicis, and below the interosseous ligament, are attached. The external or posterior descends from the pos- | terior part of the head, obtuse, and winds round below to the posterior part of the tarsal end, giving attachment to an aponeurosis intermediate between the lateral without, and the flexor proprius and solceus behind. Be¬ tween the external and the anterior is an oblique line, to which the interosseous ligament is fixed. The external surface between the anterior and posterior lines, narrow above, convex and broad in the middle, and winding spirally round the axis of the bone, is covered by the perorueus longus and brevis. An anterior, plane, is covered by the extensor longus and peronceus tertius. The internal or tibial is divided by the oblique line into two; an anterior for the extensor proprius, and a posterior for the tibialis posticus. To the posterior surface above, which is convex, the solceus is attached; and in the middle and below the flexor longus pollicis ; while, by the rough trian¬ gular surface below, the bone is articulated with the tri¬ lateral cavity of the tibia. The flbula, which is ossified in three portions, partakes of the general characters of structure common to the long bones. | jus.-' The tarsus consists of seven short irregular-shaped bones, the astragalus, the heel-bone {calcaneum, os calcis), the scaphoid, cuboid, and three cuneiform bones. The first {talus, astragalus) has a convex cartilaginous surface above for articulation with the lower end of the tibia, continuous with a similar trilateral concave surface on the inside for articulating with the malleolar process, and with a smaller triarcual surface on the outside for the fibula; two cartilaginous surfaces, separated by a deep pit below, for articulating with the calcaneum; and an anterior eminence, with a convex cartilaginous surface, for articulating with the scaphoid bone before. The calca¬ neum, which is the largest, consists of the posterior tube- 791 internal lateral sinuosity for the passage of the flexor Special en ons, that or the tibialis posticus, and the posterior Anatomy, tibial artery and nerves; and, lastly, an external lateral sunace, covered by integuments and the tendons of the lateral peroncei. The scaphoid bone is connected by its posterior con¬ cave surface with the anterior convex one of the astra¬ galus, and presents before a cartilaginous surface with three facettes for the three cuneiform bones, and on the outside a small facette for the cuboid. On the inside is a prominent tuberosity for the attachment of the tibialis posticus. The cuboid bone, which constitutes the outer margin of the tarsus, and is articulated with the trilateral surface of the calcaneum, and by a minute facette with the scaphoid bone, is chiefly distinguished by an oblique or diagonal groove, for the tendon of the peronceus longus. The third and fourth metatarsal bones are articulated to its anterior surface. I he three cuneiform bones agree in having posterior car¬ tilaginous surfaces for articulation with the scaphoid bone, and anterior ones for that with the first phalanx of the great toe, and the metatarsal bones of the second and third toes. The internal surface of the large cuneiform bone is convex, covered by integuments ; the external or fibular cartilaginous, with two facettes for articulation with the second cuboid bone and the first metatarsal. Its lower surface is irregular for the insertion of the tibialis anticus, and part of the tibialis posticus. The second cunei¬ form bone, which is the smallest of the three, and the most like its name, is wedged between the scaphoid behind, the first and third on each side, and supports the first metatar¬ sal bone before. The third, which also is not unlike its denomination, is wedged between the scaphoid behind, and the second cuneiform and the cuboid bone, and sustains the second metatarsal bone; while the third and fourth are articulated with the anterior surface of the cuboid. Of the metatarsal bones there are four; the first three The meta¬ similar to each other; the fourth, which sustains the pha-tarsal langes of the small toe, distinguished by a large oblique h01163, angular head for the insertion of the tendon of the pe¬ ronceus brevis, while that of the jmemceus tertius is fixed above. Of the other three the heads are trilateral or wedge-shaped with the base upwards, with cartilaginous facettes on the sides for mutual articulation. The bodies are cylindrical, and, tapering, terminate in round heads flattened laterally. The dorsal or upper surface is covered by the extensor tendons, the extensor brevis digitorum, and the dorsal vessels and nerves derived from the anterior tibial artery and nerve. The surface of these bones is so con¬ structed that it forms an arched or convex inclined plane, descending from the tibial to the fibular side of the foot. In the anterior or plantar surface, which is concave, are lodged the abductor hallucis, abductor minimi digiti, flexor brevis, the flexor tendons, the accessory flexor, the lumbri- cales pedis, flexor brevis hallucis, abductor hallucis, flexor brevis minimi digiti, transversalis, and the external and internal ranges of the interossei. The phalanges of the toes, in number 15, bear a gener The pha- ral resemblance to those of the fingers; but are consider!- langes. ably shorter, unless in the instance of the great toe. Like these also, they are disposed in three ranges,—metatarsal, middle, and unguinal. The bones now described are united so as to admit of The pelvic _ different degrees and forms of motion.

Special the bone to a greater distance, not only from the pelvis, Anatomy, but from the mesial plane and centre of gravity; and this character, with the great proportional length of the bone, and the extent and direction of the pelvis, constitutes the most decisive argument in favour of the doctrine, that man must support himself in the erect position on the two pel¬ vic extremities. In most quadrupeds the neck of the femur is short; the cylinder is shorter than the tibia, and not arched; and the pelvis, both by its vertical direction and peculiar dimensions, is calculated for the quadruped motion only. The femur admits of motion in every direc¬ tion,—flexion, extension, adduction, abduction, circum¬ duction, and rotation. The knee- The tibia, with its appendage the knee-pan, is articu- joint. lated to the condyles of the femur by means of an exter¬ nal and internal lateral ligament, strengthened by an an¬ terior or patellar ligament, posterior fibres, and an anterior and posterior cross ligament, contained within the synovial membrane. The effect of this arrangement, with the ana¬ tomical configuration of the articular ends, is to allow car¬ dinal opposition, or flexion and extension only. A small degree of rotation, nevertheless, may be effected. The fibula is articulated to the tibia above by a genu¬ ine capsular joint, and below by fibrous matter, and con¬ nected at its internal side by a duplicature of periosteum forming the interosseous ligament. These connections ad¬ mit of little motion, and the chief use of the fibula is to give attachment to several muscles which bend or evert the foot. The chief weight of the person, divided as it is between each lower extremity, is communicated from The ankle- the pelvis to the femur, thence to the tibia, and finally to jomt the astragalus and calcaneum behind, and the metatarsal bones before. The motion of opposition is confined to the former, which rolls backwards and forwards in the ca¬ vity formed by the lower extremity of the tibia and the fibula in the flexion and extension of the foot. In this, therefore, which forms the ankle-joint, all the motions of the foot as a whole are executed. It appears further to be susceptible of a slight degree of lateral rotation, so as to contribute to the eversion and inversion of the foot. The tarsal bones are mutually connected by cartilagi¬ nous surfaces, and secured by numerous fibrous bands, so as to admit of the gliding motion only. This motion is further between each individual articulation very limited, and its general amount is inconsiderable. The great use of the tarsal articulations is evidently stability and solidity as a base of support, not mobility. The arches The bones of the foot form two distinct and separate ot the foot. arches,—an antero-posterior and a transverse. The first is constituted by the posterior part of the heel-bone be¬ hind and the metatarso-phalangeal articulations before; and its chief use is to distribute the weight of the extre¬ mity from the astragalus, which may be regarded as the centre, to the os calcis and extremities of the metatarsal bones on each side. In standing, for example, either on one foot or both, the weight of each extremity is distri¬ buted before to the metatarso-phalangeal joints, and be¬ hind to the tuberosity of the os calcis, while the anterior part of the latter bone and the whole second range of tar¬ sal bones do not touch the ground. The second arch re¬ sults first from the arrangement of the cuneiform bones with the scaphoid, and that of the cuboid with the os calcis; and next from the arrangement of the metatarsal bones. These arches, which are indistinct in early life, become conspicuous as the bones are completed, and acquire their complete developement in adult age. These arches are of great use in the alternate elevation of each half of the person in progression, in ascending an inclined plane or a series of steps, and especially in springing and leaping. lihephalanges are articulated with the metatarsal bones Spec and with each other, so as to admit of flexion and exten- AnatoLj sion chiefly, with a very limited extent of abduction and''"x~v' ^ adduction. The articulation of the great toe, also des¬ titute of the power of opposition, abridges much its ex¬ tent of motion. < While these circumstances, with the great brevity of the phalanges, render the foot much less perfect than the hand as an organ of prehension, they extend its sphere of support, and enlarge its powers as a locomotive agent. The pelvic and thoracic extremities present several Paralli points of resemblance which have been well traced bybet'vee Soemmering. The head, neck, and tuberosities of the1!161,1!1 humerus resemble the head, neck, and trochanters of the^3^ femur; and if the lower end of the former bone is arti-m"itie“ culated both with the ulna and radius, while that of the latter is connected to the tibia only, there is still sufficient analogy between the lower ends of both bones. The tibia resembles the ulna above, with the knee-pan corre¬ sponding to the olecranon ; but the lower extremity of the tibia is represented by that of the radius, in consequence of the extensive connection of the latter bone with the carpus for the purpose of pronation and supination. The navicular and lunar bones of the carpus are represented by the single astragalus,—an arrangement which appears to be allied in the latter case to the purpose of stability and solidity. The calcaneum may be regarded as an en¬ larged os magnum, fitted for the same purpose; and even in the shape and position of the scaphoid bone the same object may be recognised. This comparison, however, it is superfluous to pursue farther. The general conclusion is, that the thoracic extremities are intended to combine with strength great extent and precision of motion, while the purpose of the pelvic is stability, solidity, and strength. SECT. II. MYOLOGY ; THE ANATOMY OF THE MUSCLES. The muscles, with their appendages the fasciae, tendons, The it and synovial sheaths, constitute the second division of theses. locomotive organs. By the term muscle, indeed, in Spe¬ cial Anatomy, is meant not only a mass of flesh adequate to effect motion, but an organ consisting of fascia, muscu¬ lar flesh, and tendon, connected by the first and last sub¬ stances to the parts, fixed or movable, to be approximated. While the middle portion is denominated belly (venter), the two extremities are most properly named attachments; though by others they have been termed respectively head or origin (caput, origo), and insertion (insitio) or termi¬ nation (finis), according as the one or the other end has been imagined to be most fixed. By the contraction of the middle portion or belly the two extremities are approximated; and according as the one is connected with a bone or soft part more movable than the other, that movable portion is approximated to the fixed. This, which is the general effect of muscular action, is well exemplified in the primary bones of the extremities, the muscles of which have their fixed end in general in the trunk, and their movable end attached to the bones of the extremities. Thus in the case of ihepecto- ralis major (p), Plate XXVII., and latissimus dorsi (l, l), Plate XXVIII., the fixed ends are in the trunk, and the movable or insertions are in the humerus; and the effect of the contraction of the belly is to carry the humerus for¬ ward over the chest in the one case, and backward on the trunk in the other. This is easily applied to other muscles, as to those of the face. The converse of this arrangement nevertheless may take place. The extremity, which in ordinary circum¬ stances is the most movable, may be converted into the ANATOMY. fixed; while that which is fixed becomes movable. Thus, itiwny- in the case of the two muscles already mentioned, the humerus may become the fixed point; and the effect will 1' be to elevate and approximate the trunk to the part to 1111LS' which the extremity is fixed. Though all the muscles are agents of motion, all are not of locomotion ; and it is chiefly the muscles connected by both ends with the skeleton, and especially those of the extremities, which are entitled to this distinction. The muscles of the face are connected always by one end, often by both, with the skin, and hence are cutaneous muscles. Those of the lower jaw and pharynx are organs of motion simply to move the parts with which they are connected in the acts of mastication and deglutition. Those of the larynx are of two orders, the common or ex¬ trinsic, connected to some of the bones of the head and chest; and the proper or intrinsic, pertaining to the laryn¬ geal cartilages only. Those of the eye and ear, external and internal, are equally unconnected with the locomotive faculty. These circumstances have induced several authors, especially the ancient anatomists, and among the moderns Winslow, to arrange the muscles according to the parts which they move. By others, however, especially Dou¬ glas and Albinus, they have been classified according to the regions which they occupy; and this method, which is certainly more strictly anatomical, has been more or less adopted by Innes, Sabatier, Bichat, and Boyer. To the first method the principal objection is, that the same muscle may pertain to different classes of organs, and may effect different purposes in each; while of the se¬ cond it must be admitted, that it communicates no in¬ formation regarding the remarkable part which the muscles perform in the complicated processes of the animal ma¬ chine. This consideration it was which induced Albi¬ nas, after a minute description of the situation, connec¬ tions, and separate actions of each muscle of the human body, to construct a table representing the various classes into which they may be divided, according to the parts on which they act; for the same reason, doubtless, Soem¬ mering arranged them according to the organs to which they belong; and for the same reason Portal, after a de¬ scription equally minute with that of Albinus, gives a se¬ cond account of the muscles as they are observed to act in the living body. In the following tabular view, modified from that given by Albinus in the fourth book of his Historia Musculorum, the muscles are arranged according to their regions.

Though rendered slightly turbid by boiling water, acids, and al¬ cohol, it does not coagulate,—a phenomenon which is to be ascribed to the small proportion of albumen which it contains. According to the analysis of Berzelius, 100 parts contain 98,4i of water, ’16 of albumen, l-42 of mu¬ riates and lactates, and only y^th of a part of soda.

It consists of two parts, an inclosing capsule and a lens no), and some other narcotics, and when the retina is in¬ sensible, these vessels seem to lose their faculty of dis¬ tension, and, perfectly empty and shrunk, allow the pu- pillar margin to approach the ciliary, etina. The retina, which is the third and internal tunic, is of the same shape as the choroid, thin, like cobweb, whit¬ ish, translucent, inclining to transparent, and very deli¬ cate. Its extreme tenuity and looseness from the choroid causes it to collapse unless inspected under water, when it may be unfolded and expanded for examination. Its outer surface is covered by a very delicate membrane, visible only in a very recent eye, discovered by Mr Ja¬ cob of Dublin. It is almost void of red vessels, unless at the part where the optic nerve enters, where one or two from the central artery may be seen. The others are colourless. The assertion that this membrane is an ex¬ pansion or production from the optic nerve, seems to be gratuitous; for it bears no resemblance to nervous mat¬ ter, or to the appearance of the optic nerve. It appears to be simply a peculiarly delicate transparent web, fitted to receive the impressions of luminous rays, and to communi- ^ cate them to the optic nerve, with which it is continuous, j fSo- On this membrane, about two lines on the temporal side inS- °f the optic nerve, and in the axis of the ball, is a circular yellow spot (^macula luted), from about a line to a line and a half in diameter, with a minute point or hole in its centre {foramen centrale). At this part the retina is much thinner than at any other; and even in the most recent eyes it presents loose folds, which Bichat regards as ca¬ daveric. The yellow spot and its central hole are seen m none of the mammalia except man and the monkeys. 115 The vitreous humour, occupying about three posterior r> fourths of the eye, is spherical and convex behind and on its lateral circumference, but concave before for receiving the posterior part of the crystalline lens. Contiguous only to the retina, it is attached to the coats by the branch sent proper. The capsule is usually distinguished into anterior and Capsule, posterior walls, both covered by hyaloid membrane, both transparent, and both firm and resisting. By boiling wa¬ ter, alcohol, or the acids, it is rendered opaque, whitish, and horny ; and it becomes yellow by contact with the air. The lens, which is perfectly transparent, consists of two portions ; an exterior, peripheral, thick, soft, adhesive, and easily removed ; an interior, central, solid, and consisting of concentric plates. Both are indurated and rendered opaque by boiling water, alcohol, and dilute acids; but the central nucleus is the firmest. When dried in the air it becomes yellowish, but retains its transparency, and may be preserved for years. These phenomena are to be ascribed to the presence of a peculiar form of albumen. According to the analysis of Berzelius, 100 parts of the substance of the lens consist of 58' of water 35-9 of pe¬ culiar matter, chiefly albuminous, 2'4 of muriates, lactates, and animal matter soluble in alcohol, 1‘3 of animal matter soluble in water, and 2*4' of membrane. The lens possesses a high refracting power; and its chief use is to concentrate the luminous rays within the eye, so as to represent distinctly the image of visible ob¬ jects on the retina. Spherical and transparent in early life, it is flattened and acquires a yellowish tint in old age. Between the capsule and lens is found occasionally a fluid which has been named liquor Morgagni. It appears to be the effect of transudation. On the structure of the lens, whether organic or not, anatomists vary. Vessels have not been recognised in it; and the most rational view is, that it is the product of an organic action probably in the capsule. The aqueous humour is contained in the anterior cham-Aqueou* ber, and in that part of the posterior which surrounds thebumour- anterior surface of the lens and vitreous humour. It con- 800 Special Anatomy. ANATOMY. Ocular muscles. I.acryrnal gland. Eyelids. sists of 98-10 parts in the 100 of water, a trace of albumen, and about 2 parts of muriates and lactates of soda. It is contained in a membrane, which lines the posterior sur¬ face of the cornea, and is supposed to cover the anterior surface of the iris. This, however, is questionable. In 1768 a membrane of this kind was described by Demours and Descemet, both of whom claimed the discovery with great eagerness and some animosity. These rival anato¬ mists appear to have forgotten that the aqueous humour may be secreted as well by the cornea and iris as by a proper membrane. The relation of the coats and humours of the eye to each other may be understood by the diagram (tig. 3, Plate XXX.), where A is the anterior chamber, P the pos¬ terior, L the lens, and c, c the ciliary processes. The other parts are easily understood from the foregoing de¬ scription. The eye is supplied with blood chiefly by the ophthalmic artery. The eyeball, thus constituted, is moved in different directions by six muscles, is moistened externally by fluid secreted from a particular gland, and is protected from ex¬ ternal bodies by the eyelids and their appendages. Of the muscles, four are straight and two oblique. The former (attollens, depressor, adductor, abductor), attached to the margin of the optic hole, and terminating in tendons inserted into the superior, inferior, nasal, and temporal parts of the eyeball, raise, depress, adduct and abduct the organ. Of the two latter, the superior oblique (troch- ledris), which is attached to the margin of the same hole, passes through a pulley-like cartilage at the inner margin ot the vault of the orbit, and is inserted into the internal region of the ball, rolls the eye forward and inward, and turns the pupil outwards and downwards ; while the inferior oblique, attached to the orbitar process of the superior maxillary bone, and inserted between the adductor and the optic nerve, rolls it forwards and turns the pupil upwards. These muscles, which occupy the apex of the orbit, are sur¬ rounded by a thick cushion of fat, on which the eyeball rolls in its movements. (Plate XXXIII. fig. 6.) In the hollow, at the outer temporal region of the or¬ bitar vault, is placed the lacrymal gland, a granular gray¬ ish body, about the size of a bean, consisting of lobules, with arteries in the intermediate furrows, derived from a branch of the ophthalmic, and accompanying veins. (Plate XXXIII. fig. 5 and 7, G, g.) These constituent lobules have been represented, on the authority of Steno in the ox, and the elder Monro in the human subject, to ter¬ minate in 7 or 8 minute excretory ducts, opening on the conjunctiva. In man, however, they were sought in vain by Duverney, Morgagni, Haller, and Zinn ; and neither Portal nor Bichat have been able to satisfy themselves of the existence of these ducts. It is nevertheless certain that the lacrymal gland secretes the tears, and that the latter issue from its lobules. The eyes are covered anteriorly by two musculo-mem- branous folds named the eyelids (palpebrce), attached to the margins of the orbit, and forming by their free mar¬ gin the palpebral opening, with commissures at each angle (canthus nasalis, et canthus temporalis). The upper eyelid, which is large, is bounded above by the eyebrow (supercilium), a cutaneous eminence, arched transversely, covered with hairs, and with the corrugator supercilii attached to its nasal end. Between each eye¬ brow is a smooth space, named the glabella or mesophryon. Into the upper eyelid the levator (fig. 5, L) is inserted. Each eyelid consists of skin externally, mucous mem¬ brane within (conjunctiva), intermediate cellular tissue, muscle, and a fibrous membrane, attached by one margin to the base of the orbit, and terminating by the other in the tarsal fibro-cartilages. These are crescentic bodies Sp placed in the free margin of the eyelids, and by their Ana firmness and elasticity giving the requisite tension to the^^ eyelids when the orbicular muscle acts, or the levator is 1.ars| relaxed. The cutaneous border of the tarsi is occupiedglant by a range of short, firm hairs, named the eyelashes (ci¬ lia). In the mucous borders are the orifices of the tarsal or Meibomian follicles, of the same character as the mu¬ ciparous follicles generally. These are placed in the sub¬ stance of the eyelid, beneath the conjunctiva, and behind the tarsal fibro-cartilages. From the inner surface of the eyelids the palpebral conjunctiva is continued over the anterior part of the sclerotic and cornea, forming the oph¬ thalmic conjunctiva. In the nasal angle is lodged a minute red body, named Cam e. the caruncle (caruncula lacrymalis), chiefly consisting of filamentous tissue and vessels covered by mucous mem¬ brane ; and behind this is a fold of tEe membrane, which has been named membrana nictitans, large in the lower animals, but often so imperfect in man as to be merely rudimentary. At the nasal end of each eyelid is a minute capillary Lacr, at orifice which leads into a horizontal canal, terminating inorific a membranous sac lodged in the depression of the lacrymal bone. These orifices, which are named the puncta lacry- malia (p, p, fig. 5), are the superior or palpebral openings of the lacrymal sac and passages, the lower aperture of which is found in the inferior nasal meatus. The tears effused from the lacrymal gland at the temporal region of the orbit are carried, by the frequent action of the orbicular muscle, over the ball, till they reach the nasal angle, where they are gradually absorbed by the capillary orifices of the puncta, and conveyed into the sac, and eventually to the nose. The eye derives nerves from six different sources, allOcul of which, however, maybe distinguished into three classes,nern the sensitive, motive, and entrophic nerves. The first consists of the second, optic or the proper visual nerves. The second class comprehends the third, fourth, and sixth nerves, of which the third or oculo-muscular are distributed to the levator palpebrce superioris, the attollens, the adduc¬ tor, the depressor, and the obliquus inferior; the fourth is entirely distributed to the obliquus superior ; while the sixth pair are confined to the abductor. I he third class of nerves is derived from the ophthalmic or quadrilateral ganglion, which is formed chiefly from the junction of a sub-branch of the naso-ocular branch of the first or oph¬ thalmic division of the fifth pair, with a small branch of the third nerve. From this arise a small superior cluster of three nerves adhering to the optic, and a large inferior cluster of eight or ten nerves, which quickly join the ciliary arteries, and are with them distributed in the ciliary circle and posterior part of the iris. (Plate XXXIII. fig. 7.) From the other branch of the naso-ocular nerve, the caruncle and lacrymal canal, with the orbicular muscle and epicranius on the one hand, and the lacrymal gland on the other, receive nervous filaments. SECT. III. THE ORGAN OF HEARING ; THE EAR. The organ of hearing consists of the auricle or external ear, with the ear-hole ; the middle ear, including the tym¬ panal cavity and its appendages; and the internal ear or labyrinth. . The auricle is a fibro-cartilaginous substance, moulded into a conchoidal shape, covered by skin, attached to the cranium by ligaments, and susceptible of motion by muscles. It is common to distinguish in it the following parts. The helix, a semicircular eminence above the ear- hole ; the groove of the helix below it; the antihelix, an eminence commencing in the groove by a superior, broad, ANATOMY. I icial oblique portion, and an inferior, narrow, horizontal one; : A "ray* the fossa navicularis; the tragus, an anterior eminence below; the antitragus, a smaller eminence behind; the lobule, a pendulous body at the base behind; and, lastly, the concha, a deep conoidal cavity leading to the ear-hole. The latter is a canal about 10 or 12 lines long in the adult. Twisted at first obliquely forward and upward, it bends slightly backwards and downwards, forming a convexity of incurvation above, and a concavity below. Though the extremities are large, the middle is contract¬ ed ; and it cannot be termed cylindrical, for its section is elliptical or oval. The structure of this tube is fibro-car- tilaginous externally where it adheres to the bone, lined by skin passing into mucous membrane, and occupied by minute follicles (glandulce ceruminosce), which secrete the wax {cerumen) formed in this canal. The nature of this secretion is imperfectly known. Though, like oil, it stains paper, it is partly soluble in tepid water, and forms with it a yellow emulsion. It is secreted at first fluid, and acquires consistence by exposure to air and admixture with dust. Alcohol has little influence on it. The in¬ ternal extremity of the auditory canal is bounded by the vertical membrane of the tympanum. Within this is the tympanal cavit}*, a space of an irre¬ gular cylindrical shape, directed obliquely, nearly in the axis of the pyramidal portion, in the base of which it is contained. This cavity is shut up externally by the ver¬ tical tympanal membrane {memhrana tympani), and is bounded within by the bony partition which separates it from the labyrinth. The memhrana, which is oval-shaped, or nearly round, and attached to the margin of the mea¬ tus externus, is directed obliquely downwards and inwards, and is so delicate that it is difficult to determine its struc¬ ture in the human subject. In the elephant, however, and Other large animals, it presents radiating fibres, which are believed to be muscular (Plate XXXVII. fig. 14) ; and Sir E. Home represents it as such not only in the elephant and whale, but in the human subject. The outer part is evidently a sort of epidermis, continuous with that of the canal; the inner is a mucous epidermis, continuous with that of the tympanal cavity; and between these the mus¬ cular fibres are interposed. The tympanal cavity communicates behind with the 801 [T banal stay ^ bhian 1 mastoid cells, and before and internally by the Eus¬ tachian tube, with the pharynx. This tube is estimated to be two inches in length, of which one and a half is in the bone of the pyramid, and about half an inch at its extremity, with the upper side completed by carti¬ lage. Narrow at the tympanal end, it becomes wide and capacious towards the pharyngeal, and presents at length a free open extremity, forming a fissure at the upper and lateral part of the pharynx. The cartilaginous end is covered by mucous membrane continuous with the pha¬ ryngeal, and is surrounded by the peristaphylini, the action of which is believed to separate the walls of the aperture. Within the tube, and towards the tympanal end, this mem¬ brane parts with its pharyngeal spongy character, and be¬ comes thin and semitransparent where it lines the bone. The same kind of membrane, partaking of the characters of periosteum and mucous, is continued over the tympanal cavity, and into the mastoid cells. ‘ - of Above the Eustachian tube is a thin osseous plate, which Jeiisseparates it from a small canal, convex below, concave We,above, and which, commencing in the fissure between the squamous and pyramidal portions, terminates in the tym¬ panal cavity. In this canal is lodged the internal muscle of the malleus, one of the tympanal bones, pal These are four in number, very minute, and denomi¬ nated, from their mechanical figures, the hammer (maU VOL. II. leus), the anvil (incus), the lenticular or round bone (os Special orbiculare), and the stirrup (stapes). Of these the malleus is Anatomy, attached to the vertical membrane by its handle, while its head is articulated with the body of the incus. The latter presents two limbs or branches, to the larger of which the stapes is articulated by the interposition of the lenticular bone; while the base of the former rests on the membrane of the foramen ovale. These articulations are secured by cap¬ sules, which allow the bones to move freely on each other ; and for this purpose the stapes is provided with one muscle, and the malleus with two, an internal already mentioned, and an external passing from the spinous process of the sphenoid bone to the slender process of the malleus. On the motions of these, however, and their part in the pro¬ cess of hearing, we have only conjectural statements. The internal bony wall of the tympanal cavity presents Foramen two apertures and a convex intermediate eminence. Of ovale, the apertures, the first, which is named the oval or vesti-fenestra bular aperture (foramen ovale, fenestra ovalis), is situate ova^s’ above, oval transversely, with its great diameter horizontal antero-posterior. It communicates with the vestibule, but is closed by a fine membrane, to which the base of the stapes is fixed, and for the insertion of which its margin is grooved. The oval aperture is bounded above by a round Promon¬ prominence, corresponding within to the Fallopian aque-tory. duct, and below by a large convex eminence named the promontory (promontorium), which indicates the situa¬ tion of the cavity named the vestibule. Before and above the promontory is the extremity of the thin osseous plate which separates the Eustachian tube from the canal of the internal muscle of the malleus; and behind is an oblique cavity, which is placed between the lower entrance of the mastoid cells and the pyramid. Below the promontory is the round or cochlear aperture (foramen rotundum, fenestra rotunda), trilateral in early life rather than round, and still preserving in the adult the tendency to this shape; smaller than the oval, and directed backwards and out¬ wards. The round aperture is shut by a membrane, the direction of which is oblique to that of the tympanum, and one side of which is towards that cavity, while the other forms part of the cochlea. At the upper part of the tympanum is a triangular-Mastoid shaped opening, which leads into a rough short canal, cells, terminating in the mastoid cells. These are analogous to the cells of the ethmoid, sphenoid, and occipital bones. They are lined by fibro-mucous membrane, and their use is to afford a posterior sonorous apartment for the vibra¬ tions produced in the tympanal cavity. Near this triangular opening is a small bony process named the pyramidal, in which is a canal for the fleshy part of the stapedius, while the tendon issues from its orifice. Near the base of the pyramidal process is the hole by which the nerve of the tympanum (chorda tympani) passes through the glenoid fissure. The labyrinth consists of the vestibule, three semicircu- Labyrinth, lar canals, and the cochlea. By removing the stages and stapedial membrane the Vestibule, oval aperture is opened, and communicates with the vesti¬ bule. This cavity, which is irregular in shape, about the size of a grain of barley, is bounded without by the tym¬ panum, within by the internal auditory canal, before by the cochlea, behind by the semicircular canals, and above and below by the solid bone of the pyramid. It is lined by a membrane common to the whole labyrinth. Besides the oval aperture by which it is separated from the tympa¬ num, it has, above, the two anterior openings (ampullulai) of the superior vertical and horizontal canals ; behind, the two openings (ampidlulce) proper to the posterior verti¬ cal and horizontal canals, and the common opening of the 5 i 802 ANATOMY. Cochlea. Special two vertical canals; and before and below, the orifice of the Anatomy, external scala cochleae. There is still another aperture, which leads into a canal of1 the "es discovered by Cotugno, named the aqueduct of the ves¬ tibule and' tibule* This, which, though distinct in some subjects, is aperture, almost imperceptible in others, is near the common orifice of the vertical canals ; and from it the aqueduct proceeds first upwards, where it is narrow, then backwards and downwards, widening, and terminates in the fissure on the posterior surface of the pyramidal portion. Semicircu- The semicircular canals, situate behind the vestibule, hr canals, are three in number, two vertical and one horizontal. Of the former, one is superior, inclosing by its curvature the substance of the pyramid, and forming a convexity in the adult, very distinct in the fcetus ; while the other, which is posterior but inferior, is placed with its plane correspond¬ ing to that of the posterior surface of the pyramid. The third is placed horizontally between the other two, form¬ ing a curvature with the convexitv towards the base of the pyramid. (Plate XXXIII. fig. 8/9, and 10.) Though denominated semicircular, these canals are larger than semicircular, and may be compared to hollow cylinders, incurvated so as to form large circular segments. Each canal has an enlarged extremity named ampullula ; and as these two vertical canals have one in common, there are five ampullulae. They are lined by the common la¬ byrinthine membrane, and contain a pellucid fluid. The cochlea, which forms the third part of the labyrinth, is a conical canal turned spirally within itself, so that its base is at the lower part of the vestibule, and its apex at the anterior side of the pyramid, with the orifices for the auditory nerve inclosed in the centre of its turns, while the convexity is directed towards the lower margin of the pyramid. The cochlear canal is divided longitudinally by a thin sharp-edged plate, half bony half membranous, into two independent cavities, the superior of which communi¬ cates with the vestibule, while the inferior is bounded by the membrane of the round aperture. These cavities are distinguished as the vestibular and tympanal {scala vestihuli and scala tympani) respectively. At the top they termi¬ nate in a common cavity named the funnel {infundibulum). Both are lined by a delicate membrane, in which are con¬ tained the ramified filaments of the eighth or auditory nerve. (Plate XXXIII. fig. 10.) In the tympanal scala, near the round hole, is a minute aperture leading to a narrow canal, which gradually en¬ larges as it ascends, till it terminates by a slit on the pos¬ terior surface of the pyramidal portion, as formerly men¬ tioned. ' This is the aqueduct of the cochlea, first describ¬ ed, like that of the vestibule, by Cotugno. These different cavities are supplied with blood chiefly sels of the from minute branches of the auditory, a vessel generally ear. derived from the basilar trunk or the vertebral arteries. From the meningeal artery also minute branches enter the auditory canal, and anastomose with those of the auditory artery; and the internal carotid sends to the membrane of the tympanal cavity a branch, the capillary ramifica¬ tions of which anastomose with those derived from the pharyngeal, transmitted by the walls of the Eustachian tube. The eighth or the proper auditory nerve enters the coch¬ lea by several minute apertures in the internal meatus, and is divided into two fasciculi, of which the posterior and largest is expanded in the form of soft pulpy brush-like filaments, like a hair-pencil, in a pellucid fluid, in the coch¬ lea ; while the smallest, which is anterior, is distributed partly to the bottom of the hemispherical cavity of the vestibule, partly to the beginning of the spiral lamina. (Fig. 10.) Aqueduct of the cochlea. Blood-ves- Auditory nerve. The tympanal cavity is chiefly for the purpose of con- Spe< [ veying and augmenting the intensity of sonorous vibra- Anati ^ tions, while the shape of the auricle is supposed to collect them. But of the mechanism of its operation we know nothing satisfactory. The essential part of the organ of hearing is the labyrinth. SECT. IV. THE ORGAN OF TASTE. It is impossible to define the exact limits of the sense of taste. More or less diffused over the cavity of the mouth, it is particularly confined to the tongue and palate. The former, nevertheless, is remarkable for being a mus¬ cular organ, which combines with the faculty of taste the power of prehension and transmission of the alimen¬ tary articles both during and after mastication, and is further an essential agent in the faculty of articulation. It is requisite, therefore, to give a short account of the mouth, the palate, and the tongue. a. The mouth is the cavity formed by the lips before, the The pharynx and isthmus faucium behind, the palatine vaultmoutl above, the intramaxillary membrane and muscles below, and on the sides by the cheeks. Its horizontal direction may be regarded as one among other proofs of the neces¬ sity of the erect biped attitude. The mouth is lined by a mucous membrane, soft, spongy, red, and vascular. It may be traced from the inner or alveolar surface of the lips to the inner surface of the cheeks on each side over the gums, where it is continuous with that of the aheolox folliculi, over the inner surface of each maxillary ramus, and the attached muscles and glands below, until it is identified with that of the tongue, and above over the palatine vault back to the uvula. In these several points, though its organization is the same, its mechanical arrangement varies considerably as the parts are fixed or movable. Thus, on the palatine vault and at the gums it is tense, and adheres pretty firmly to the fibrous layers forming the periosteum of these parts. In the angular space between the lips and gums, however, in that between the inner surface of the alveolar arch, and all over the lower part of the mouth, where it is connect¬ ed to the inferior surface of the tongue, it is extensive, loose, moves easily over an abundant layer of filamentous tissue, and is generally disposed in irregular folds. Ad¬ hering to the internal spine of the lower jaw, a fold or du- plicature containing condensedfilamentous tissue is reflect¬ ed, to be attached to the median line of the tongue, and forms the frenum of that organ. In all points it abounds with muciparous follicles. It also presents on each side of the tongue the orifices of the sublingual glands. The mouth has two outlets, an anterior or facial formed Oiitli by the lips {labia), and a posterior or pharyngeal formed* em by the velum palatinum and its appendages. The lips are musculo-membranous folds, attached all Eie round to the superior and inferior jaw-bones, above and below the alveolar arches, and parted by a transverse opening or fissure into upper and lower, with right and left commissures or angles {canthi). In the Negro race they are particularly bulky and flaccid, with their free margins {prolabia) much everted; but in the Asio-Euro- pean they are thinner, and more constricted. Each lip consists externally of skin continuous with that of the face, internally of mucous membrane continu¬ ous with that of the mouth, with interposed filamentous tissue and muscles, well supplied by blood-vessels and nerves. The point of union between the skin and oral mucous membrane is marked by a rounded edge, covered by a thin, vermilion-red, soft and delicate pellicle, extending between of til. ANATOMY.

In singing on false notes the uvula is progressively ele¬ vated, as the voice ascends. In the space between the anterior and posterior pillars are contained the tonsils (tonsillce, amygdala), bounded above by the commissure of the pillars ; below by the la- matics. The lips are supplied with blood from the branches of the external carotid. The external maxillary sends a large branch over the angle of the inferior jaw, upwards and forwards to the labial commissures on each side. This vessel, which is generally named the labial, sends oft' teral part of the base of the tongue,”where the/are'con- two, a superior and inferior labial, which are subdivided tinuous with the muciparous glands of that organ; before into numerous minute branches, anastomosing freely with by part of the constrictor isthmi faucium ; and behind by each other, and with the submental and inferior dental the pharyngo-staphylinus.

The lobules the inferior maxillary, with anastomotic communications present minute cavities, isolated or mutually communi- ! palate, from the 8th or facial nerve. , b. The posterior or pharyngeal outlet of the mouth (isth¬ mus faucium) is formed by the movable or soft palate (velum palatinum), a membranous fold attached to the posterior margin of the palatine quadrilateral bones, and hanging with its free margin downwards. This curtain, which has two surfaces, an anterior or oral and a posterior or pharygneal, is shaped like a double arch, meeting on the mesial plane, where it terminates in an elongated conical prominence, sup¬ posed to resemble a grape suspended by its stalk, and de¬ nominated therefore uvula (craptAjj), but which, with the lateral arches, bears a closer resemblance to the descending cusp of a Gothic window. From this central process the arch rises on each side; and when it passes to the outer edge of the palate-bone on each side, it is supported by eating, in the recess of which are minute pores, the ori¬ fices of the excretory ducts, and from which a watery but viscid liquor may be expressed. In short, each tonsil may be regarded as an assemblage of muciparous glands, destined to secrete fluid for lubricating the throat during the process of deglutition, when it is most abundant. The chops (huccce) or lateral walls of the mouth con¬ sist externally of skin, internally of mucous membrane and of an intermediate layer of muscles imbedded in abundant filamentous and adipose tissue. The cutaneous covering is in general thin, soft, and pe¬ culiarly smooth, with a minutely distributed and abun¬ dant capillary system, which approaches in its characters to the erectile. Beneath the cutaneous covering is the zygomaticus ma- two musculo-membranous vertical columns, united at the for, the only muscle proper to the cheek, resting on a top, but separating and forming an intermediate cavity, in which the tonsil on each side (amygdala) is contained. The palatine curtain consists of two folds of mucous membrane, with interposed filamentous tissue and muscu¬ lar fibres. The anterior mucous membrane is of the same character with that of the mouth, with which it is con¬ tinuous. The posterior, which is continuous with the nasal mucous membrane, partakes of the charac ters of that tissue, and is redder and more vascular. These two meet in the lower margin of the velum, and pass into each other. Both are well supplied with mucous follicles, but the anterior or oral division most copiously. These mucous membranes rest on filamentous tissue; and beneath this we find, in the middle, the levator or azy¬ gos uvulce, and on the sides the levator of the soft palate thick layer of fat; below this is the buccinator, perforated by the parotid duct; and to the filamentous tissue inside, the buccal mucous membrane, furnished with numerous muciparous follicles, adheres. The orifice of the parotid duct is seen opposite the second molar tooth of the supe¬ rior jaw. c. The tongue is a longitudinal muscular organ, invested The by a mucous membrane provided with numerous papilla, tongue, attached behind to the hyoid bone, below to the mu¬ cous membrane of the mouth, and free above and before. It is shaped like a flattened cone, and is distinguished into a base and tip (apex), an upper and a lower surface, and two sides. The base is somewhat thick and broad, but becomes thin and narrow near the hyoid bone. I rom about 1 inch (peristaphylinus internus), which are expanded in the ve- anterior to this, however, to near 1,] from the tip, the thick lum. The anterior pillar consists of mucous membrane ness and breadth are nearly uniform. 1 he tip (apex) is enveloping the fibres of the constrictor isthmi faucium; the posterior incloses those of the pharyngo-staphylinus ; and both expanding into the velum, augment its thickness and regulate its motions. Between the internal peristaphylini, which are imme flat and rounded or paraboloid in ordinary circumstances, but may be made by muscular action to taper to an angu¬ lar point. The upper surface, which is free, presents the lingual mucous membrane divided into right and left halves by a superficial furrow. On this, near its posterior end, diately below the pituitary or posterior mucous membrane is a depression, variable in size, named the foramen cacum, of the velum and the anterior, is an aponeurotic web, in which are contained the orifices of muciparous follicles, connected with the circumilexi, which, fixed to the margin From this on each side proceeds an oblique line div erging of the palatine vault, tends to consolidate the velum. forward, and forming with that of the opposite side an The free margin of the velum forms the upper boundary acute angle, with the angular point behind. These an- ANATOMY. 804 Special gular lines, which are variable in shape and disposition, Anatomy, depend on the elevation resulting from the mucous glands at the base of the organ. The rest of the surface pre¬ sents the minute conical eminences named, papillce, which belong to the mucous membrane. The lateral margins, which are smooth and void of papillce, form the transition from the upper free papillated surface to the lower, which is chiefly attached by folds of the oral membrane to the lower region of the mouth. The tongue consists of various muscles, connected by filamentous tissue, some adipose tissue, and invested by mucous membrane. Muscles. The muscles are of two orders, those common to the tongue and contiguous parts, and those proper to the tongue. The common or extrinsic muscles are, the stylo¬ glossi, between the styloid process and margins of the tongue ; the hyoglossi, between the branches of the hyoid bone and the margins of the tongue; and the genioglossi, from the upper internal mental tuberosities to the lower part of the organ. The proper or intrinsic muscle (lin- gualis) consists of two parallel layers of muscular fibres running along the lower surface of the organ, and a mass of fleshy fibres irregularly arranged and mutually crossing in all directions, and intermixed with a considerable quan¬ tity of soft but elastic oleo-adipose matter. Of the lingual mucous membrane the most important circumstances are, the leathery thickness and distinctness of its corion and epidermis on the superior surface of the organ, and the papillary eminences with which it is marked. Lingual These papillce. may be distinguished into three orders; papilke. the irregular or granular at the base, the tubercular or rounded about the middle third, and the conical or point¬ ed at the apex. The granular which vary in number from 10 to 15 or 16, are of a spheroidal or ovoidal shape, and are arrang¬ ed on each side of the median furrow, obliquely behind the sides of the angle already mentioned. These bodies are evidently muciparous follicles; and it is in general easy to distinguish the orifice of the excretory duct by the eye or a moderate lens. They seem to receive fila¬ ments from the glosso-pharyngeal nerves, which enter the tongue immediately beneath these granular glands. The tubercular papillce, which are much more nume¬ rous, have rounded truncated summits, and occasionally pedunculated stalks. They are irregularly distributed towards the middle, margins, and apex of the tongue, promiscuously with the conical; and their nature is un¬ known. The conical or acuminated papillce, though occupying the two anterior thirds of the lingual surface, are never¬ theless most numerous towards its apex, where they are also smallest, and somewhat inclined forward. These papillce are asserted by the older anatomists to be the terminations of nervous twigs; and Cloquet allows them to be the expansion of the filaments of the lingual nerve. This, however, is an evident relic of the fanciful represen¬ tations of the older anatomists, and is not supported by inspection. I have examined the structure of the lingual papillce in many instances, and in none have I seen any ground for the assertion that they consist of nervous fila¬ ments. They do not even receive a larger proportion than other parts of the lingual membrane. The papillce consist chiefly of numerous minute blood-vessels, rather tortuous, and communicating directly with veins envelop¬ ed in fine filamentous tissue; and from this they derive their property of erection, while their mucous surface se¬ cretes mucus copiously. These papillce are further the seat of the white fur with which the tongue is liable to be coated in affections of the stomach. The yellow fur Spe 1 seems to be produced from the mucous surface generally. Anally The tongue is supplied with blood by the lingual ar-^^-<- teries, branches of the external carotids, and by the pala-Arter ■ tine and tonsillary of the external maxillary. The blood is returned by the superficial vein, the ranine, the lingual, and submental. The nerves of the tongue are derived from three differ-NervJ ent sources; the inferior maxillary, or third branch of the fifth pair; the glosso-pharyngeal ; and the hypoglossal. From the first it receives the lingual nerve, which, after sending filaments to the sublingual gland, the styloglossus, genioglossus, and proper muscle of the tongue, is distri¬ buted chiefly to the upper surface, sides, and apex of the organ. This is believed to be the proper gustatory nerve. From the second it receives a lingual branch, which, pass¬ ing between the styloglossus and hyoglossus, gives fila¬ ments to these, the proper muscle, and the posterior part of the genioglossus, and to the granular papillce. By means of this nerve the motions of the tongue and pharynx are made to associate. The third, which is distributed chiefly to the muscles attached to the hyoid bone, sends filaments also to the hyoglossus, styloglossus, and chiefly to the genioglossus. The hypoglossal is believed chiefly to preside over the motions of the tongue, and probably those destined for articulation. The tongue is one of the best examples in the human Uses, body, of the felicity with which a single organ may be adapted to a great variety of useful purposes. Endowed with the common sensation of tact, diffused over the body at large, its mucous investment is so organized that it re¬ cognises readily the peculiar impressions communicated by sapid bodies. To render it more serviceable in this respect, its muscles make it an organ of prehension, and elongate, contract, inflect, incurvate, or extend it, so as to apply objects placed on its tip to the palate or any part of the mouth. By the same means it becomes an important agent in the prehension of food, and in deglutition, by transmitting the masticated food to the pharynx. Lastly, it is a most essential and necessary organ of speech, and, by the nice motions which it undergoes, enables the human race to pronounce literal sounds and articulate consonants, which without its aid would be unutterable. Of this the letters 1 and r are examples. d. Connected with the organs of taste are the salivary Saliva| glands, of which there are three pairs, one on each side ofS^anil: the mesial plane ; the parotid, submaxillary, and sublingual. The parotid, so named from its situation before the ear, Parol is the largest of all the salivary glands. It consists of two parts, the parotid proper, a large oblong mass placed in the deep angular cavity formed by the maxillary ramus and the mastoid process; and the soda parotidis, a large flat irregularly oval mass extending beneath the skin of the face. Partaking of the general characters of glandu¬ lar structure, it is supplied with blood from the external carotid, by the temporal and transverse facial; its veins open into the external jugular; and it receives numerous nervous filaments from thefacial and the ascending branches of the cervical plexus. It has an excretory duct, named also the duct of Steno (ductus Stenonianus), which, quitting the surface of the gland a little above the middle of the upper margin of the masseter, proceeds horizontally over the tendinous part of that muscle, and, sinking into the filamentous adipose tissue of the cheek, perforates the buccinator, and termi¬ nates in the mouth at the level of the second superior molar tooth. The submaxillary or intramaxillary is smaller than the Sub-n parotid. Oblong in shape, it is placed on the internal pitilhny f ANATOMY. Ik | (jcial of the lower jaw, bounded by the internal pterygoid and |4ijomy. mylo-hyoid above, the lingual nerve, the stylo-glossus and hyo-glossus, and the external maxillary artery behind, and below by the latissimus colli and integuments. Blood it derives from the lingual and external maxillary arteries, and nerves from the lingual and the myloid branch of the inferior dental. Its excretory duct, named, from its dis¬ coverer, the duct of Wharton, terminates on the side of the frenum, in a narrow tuberculated orifice, ub. The sublingual gland is the smallest of the three. Pa¬ il rallel to that of the opposite side, it is separated from it by the base of the two genio-glossi, and rests on the mylo- hyoideus, which separates it from the intramaxillary. Oc¬ casionally, however, these two glands communicate by a slip from the intramaxillary below the muscle. It is sup¬ plied with blood by the sublingual, ranine, and submental arteries; and its nerves proceed from the lingual and hy¬ poglossal. Its excretory ducts are manifold, and terminate either in several orifices on the sides of the frenum, or unite in a single tube, opening in the same region. The use of these glands is to separate from the blood a watery but somewhat saline and sapid fluid, which has the twofold office of preserving the gustatory membrane in its necessary moisture, and of mixing with the food during mastication. The saliva consists chiefly of water, holding in solution hydrochlorate of soda, sulpho-cyanic acid, and a minute portion of animal matter intermediate between albumen and osmazome. The presence of sulpho-cyanic acid, an active poison, is remarkable ; nor is the purpose of such an agent known. From the saline matters in this fluid the tartar of the teeth is deposited; and occasionally minute concretions are formed in the glands or their ducts. That appearing in the ducts of the sublingual forms one variety of the affection named ranula. CHAP. III. THE ORGANS OF VOICE. Voice is of two kinds, according as it consists in the mere voluntary utterance of sound, or what is named, in refer¬ ence to the animal world, cry, or in the utterance of certain peculiar modifications of this, denominated therefore arti¬ culate voice, or simply speech. Inarticulate voice is com¬ mon to all the Mammalia and Birds. By the posses¬ sion of articulate speech, however, man (/Asgo-^) is parti¬ cularly distinguished from the animal world in general. These two forms of voice have two distinct organs. For inarticulate voice the larynx is placed at the superior ex¬ tremity of the windpipe; and for that of speech, to the larynx are superadded the articulating powers of the teeth, lips, and tongue. The larynx is a tubular organ, consisting of cartilages invested by membranes, connected by ligaments, and moved by muscles. The cartilages are five in number, the thyroid, cricoid, two arytenoid, and the epiglottis. The thyroid cartilage, which forms the anterior and lateral region, consists of two lateral halves united on the mesial plane, where they form an acute salient angle, dis¬ tinct beneath the integuments, and forming what is named thepomum Adami. The anterior surface is slightly concave, covered by the thyro-hyoideus, with an oblique line, to which the muscle now mentioned, the sterno-thyroideus, and infe¬ rior constrictor, are attached, and a posterior space covered by the two latter muscles. The posterior surface of the thyroid has in the middle a re-entrant angle, to which are attached the ligaments of the glottis and the thyro-aryt(enoi~ dei; on the sides two plane surfaces, corresponding above to tiie cellular tissue of the thyro-arytcenoidei, and below 805 to the lateral crico-arytcenoidei, and some fibres of the Special cnco-thyroidei attached to this part. Anatomy. Each lateral half is quadrilateral and quadrangular. the upper margin, which is obliquely sinuated like an f, the thyro-hyoid membrane is attached. To the lower, which though shorter is also sinuated, the crico-thyroid membrane and the crico-thyroidei are attached. The posterior margins, which are oblique and give at¬ tachment to several fibres of the stylo-pharyngei and pa- lato-pharyngei, terminate above in an elevated pointed process incurvated inwards and forwards, connected by a ligament to the hyoid bone, and below in a similar process, shorter however and triangular in shape, and articulated by its tip with the lateral process of the cricoid cartilage. The cricoid or annular cartilage (xgaog, annulus'), which Cricoid occupies the lower part of the larynx, is a complete ring cartilage, of cartilage, narrow before, and broad and elevated be¬ hind, where chiefly it constitutes the laryngeal cavity. Convex in the middle, where it is subcutaneous, it widens laterally where the crico-thyroidei are attached; and far¬ ther back, where it is covered by the thyroid cartilage, it presents the lateral process covered by synovial mem¬ brane for articulation with the triangular process of the thyroid. Its posterior region is broad and quadrilateral, with a ridge on the median line covered by the pharyngeal membrane only, and two depressions on each side, to which the posterior crico-arytcenoidei are attached. The inner surface, which is concave, narrow before and broad behind, is covered by the laryngeal mucous membrane. The superior margin presents before a large notch, to which the crico-thyroid membrane is fixed, laterally the insertion of the lateral crico-arytcenoidei, and behind two convex surfaces, oblique in direction, covered by synovial membrane for articulation with the arytenoid cartilages, and between which this margin is covered by the aryte¬ noid muscle. The lower margin, less irregular, descend¬ ing before, sinuated on the sides and notched behind, is united by a fibro-mucous membrane to the first ring of the windpipe. The arytenoid cartilages are two small bodies, triangu- Arytenoid lar and pyramidal in shape, placed at the posterior part cartilages, of the larynx, in the upper margin of the cricoid cartilage. In each arytenoid cartilage may be recognised a concave anterior surface for the arytenoid gland, a concave posterior surface for the arytenoid muscle, an internal surface covered by laryngeal mucous membrane, a base concave and oval, covered by synovial membrane for articulation with the cri¬ coid, and a thin, convex summit, supporting a small carti¬ lage (cornicula laryngis), invested by mucous membrane. These bodies, which are named the tubercles of Santo- The tu- rini (capitula arytcenoidum) by whom they were discover- bercles of ed, are conical in shape, with a concave base for articulat- Santorini, ing with the summit of each arytenoid cartilage, and a pointed apex incurvated inwards and backwards. To their surface, with part of the arytenoid, the thyro-arytenoid ligament is fixed, and forms the beginning of the glottis. These bodies partake of the general characters of car¬ tilage, and are invested by perichondrium. I he thyroid and cricoid have a great tendency to ossification; and it is rare to find them unossified in advanced life. The epiglottis is a thin slip of fibro-cartilage, of a para- The epi- boloid shape, covered by mucous membrane, attached at glottis, its base by cellular tissue to the inner surface of the hyoid bone and the upper margin of the thyroid carti¬ lage, and by duplicatures of mucous membrane to the summits of the arytenoid cartilages. In this duplicature, The cunei- on each side, is suspended a minute wedge-like cartilagi- f°rm cartl- nous tubercle, with the base upward, named the cuneiform. iaSe:,‘ These cartilages are articulated so as to admit of mo- 800 ANATOMY. Special tlon at the points already indicated. The articulations Anatomy. are secured by ligamentous capsules; but the most im- portant ligament is the thyro-arytenoid, which passes from the base of each arytenoid cartilage to the re-entrant angle of the thyroid, where the fibres are mutually mixed with that of the opposite side. The thyroid moves on the cricoid, which may be regarded as the base of the or¬ gan ; and the two arytenoid move on the upper margin of the cricoid. The epiglottis is depressed over the laryngeal opening by the motion of the tongue in deglutition. The agents of motion in the larynx are of two kinds; ls£, those which move the whole organ in relation to the neighbouring parts; and, ildly, those which move the com¬ ponent parts of the larynx in relation to each other. To the former class belong the sterno-thyroid, thyro-hyoid, and inferior constrictor muscles, with those attached to the hyoid bone, the elevation and depression of which the larynx follows. The second comprehends the crico¬ thyroid, the posterior crico-arytenoid, the lateral crico¬ arytenoid, the thyro-arytenoid, and the arytenoid. The connections and relations of these muscles it is super¬ fluous to detail more minutely than may be understood from the description already given of the cartilages. It is sufficient to say, that while the crico-thyroid causes the thyroid cartilage to perform a swinging motion on the cri¬ coid, the posterior crico-arytenoid draws the arytenoid cartilages back, the thyro-arytenoid draws them forwards, the lateral crico-arytenoid separates them from each other, and the arytenoid, sometimes distinguished into trans¬ verse and oblique arytenoid muscles, approximates these cartilages in different degrees, according to the act in which they are used. The several parts now mentioned are invested on the inside by mucous membrane, continuous above with that of the pharynx and tongue, and below with that of the trachea. Proceeding from the former boundary, it may be traced over the epiglottis and its gland, on the mesial v plane and the thyro-arytcenoidei, and on the sides from the inner surface of the thyroid cartilage before to the outer margin and base of the arytenoid cartilages behind. At this part it rises to form two folds with rounded margins, extend¬ ing from before backwards, and forming on the outsides a cavity with the arytenoid cartilage. These folds, though occasionally named the superior ligaments of the glottis, are truly mucous membrane doubled, with interposed filamentous tissue. They form an intermediate triangular space, with the base before and the apex behind. The inner surface of this membrane, directed to that of the op¬ posite side, is concave, and forms a sort of pouch called the ventricles of the larynx (sacculi laryngis). The mem¬ brane here covers the thyro-arytenoid ligaments, over which it is tensely stretched, so as to form inferior folds, much tenser and firmer than the superior ones. These lower folds, which form a triangular interval with the base behind and the apex before, are the proper ligaments of the larynx, or vocal chords (chordoe. vocales); and the in¬ termediate fissure is named the glottis, or rim a glottidis. Though this opening is triangular in the dead body, its shape varies much in the living. By the joint action of the posterior crico-arytanioidei and the arytcenoidei trans- versi, the thyro-arytenoid ligaments maybe rendered'tense, the arytenoid cartilages approximated, and the fissure of the glottis become a mere slit. Though it is impossible to adopt all the views of Do- dart regarding the powers of the thyro-arytenoid ligaments, it is certain that their tension and relaxation, with the mutual approximation of the arytenoid cartilages, are the essential agents of voice. Without the air passing through the glottis there is no voice. The glottis is also the organ by which the quantity of air admitted into the trachea is Spt™ regulated. By means of its muscles it may be shut, and Anat)rr, the breath retained, so as to fix the chest during any great effort. By contracting it, also, during coughing or forcible expiration, the air is forcibly expelled from the lungs, and necessarily carries at the same time foreign bodies. At the base of the epiglottis, in the angle between it and the thyroid, the laryngeal membrane presents several orifices, which may be traced to a cluster of follicles im¬ bedded in the submucous tissue at this part. This clus¬ ter has been named the epiglottic gland. A similar glandular body, in the anterior depression of each arytenoid cartilage, is named the arytenoid glands. Of the body named thyroid gland, situate on the sides of the upper end of the trachea, and generally referred to the appendages of the larynx, nothing is known. With the larynx it has certainly no relation. The blood-vessels of the larynx are the superior thy¬ roid or laryngeal, the first branch of the external carotid, and the inferior laryngeal branch of the inferior thyroid, the second branch of the subclavian artery. The nerves are derived from the pneumogastric or ner- vus vagus, and may be referred to three divisions; the internal laryngeal, distributed to the proper muscles of the larynx; the external laryngeal, distributed to the thyro-pha- ryngeus, the sterno-thyroid, hyothyroid, and crico-thyroid; and the recurrent, distributed to the laryngeal membrane, the thyro-arytenoid, and posterior crico-thyroid muscles. The division of these nerves, or of the pneumogastric, from which they proceed, is followed by palsy of the muscles, and inability to open the glottis at will, or retain it open; and the result is dyspnoea, terminating in asphyxia CHAP. IV. THE NERVOUS SYSTEM. The nervous system includes two general divisions, a central and a distributed. The first is collected in a single and indivisible mass, contained in the cavities of the cranium and vertebral column, and may be designated by the general appellation of brain {cerebrum). The second consists of long chords connected with some of the central portion and with each other, and distri¬ buted in every direction through the body in the mode of ramification. These are distinguished by the name of nervous chords or nerves {nervi). SECT. I. THE BRAIN AND ITS MEMBRANES. § 1. the brain. Plate XXX. The brain may be considered as a continuous organ, con¬ sisting of three divisions;—the convoluted, the laminated, and the smooth or funicular portions. Of these divisions, which are framed according to the peculiar external con¬ figuration of each, the first part corresponds to what is called the brain proper {cerebrum); the second to the small brain {cerebellum) ; and the third to the oblong body contained in the vertebral column, and known under the name of spinal chord. The convoluted portion presents two surfaces, an outer or convoluted, and an inner or figurate. I he laminated portion in like manner presents two surfaces, an outer or laminated, and an inner or central. The third has only one exterior surface. The shape of the first two divisions is like that of the cranial cavity in which they are contained, oblong sphe¬ roidal or ovoidal, with the small extremity of the ovoid be¬ fore, and the large one behind. The human brain is larger and heavier in proportion than that of any other animal. The three parts, the brain, cerebellum, and spinal chord, after being washed and ANATOMY. ial emptied of blood, weigh in the adult from two pounds my.^five ounces to three pounds three ounces, and at an ave¬ rage about three pounds; and of this the brain alone weighs two pounds. The statement of Haller, that the brain weighs five pounds, is incredible, unless it be under¬ stood of Troy weight, in which case even it seems exag¬ gerated, since of more than 200 brains weighed by Soem¬ mering, not one amounted to four pounds. The statement, that the brain of Cromwell weighed six pounds and one fourth, seems equally incredible. The specific gravity of the adult brain is to water as 1031 to 1000. This, how¬ ever, varies with age. The cerebellum weighs about five or six ounces, and is therefore about the seventh part only of the weight of the brain. The brain (cerebrum) is divided above and before into (^' two lateral halves, named hemispheres (hemisphceria), 1 right and left, separated by a deep furrow, in which the vertical, crescentic, or dichotomous portion (falx) of the hard membrane is received. Each hemisphere is bounded by a superior or convex, an inner or plane, and an inferior convex and concave surface. The lower surface of each hemisphere, also, anatomists distinguish into three lobes, an anterior, posterior, and middle. The cerebellum is also divided into two hemispheres, separated by a middle furrow of less depth, receiving, as that of the brain, a crescentic production, smaller in size, from the hard membrane. The exterior surface of the convoluted division is form- :e ed into eminences longitudinal and rounded, but directed in various ways, named convolutions or circumvolutions (gyri, Soemmering, Wenzel), and separated from each other by deep hollows (sulci). To see this surface, which is termed the convoluted, the vascular membrane termed •pia mater (meninx tenuis) must be removed. The convoluted surface of each hemisphere may be divided into five regions : 1. The commutual or dichoto¬ mous ; 2. the lateral-superior or convex; 3. the antero¬ inferior or frontal; 4. the medio-inferior or spheno-tem- poral; and 5. the posterior or cerebellic region. 1. The commutual, plane, of a shape nearly semicircular, forms the mesial boundary of each hemisphere, and cor¬ responds to the falciform or dichotomous portion of the hard membrane (iirpiy^ meninx dura), by which it is separated from the similar surface of the opposite he¬ misphere. Before and behind it extends from the supe¬ rior to the inferior surface of the brain; but a consider¬ able portion of its middle is terminated by the upper sur¬ face of the middle band (mesolobe, corpus callosum), which lies between the two hemispheres. It is contained be¬ tween the semicircular and the rectilinear margins. 2. The convex region occupies the anterior, upper, lateral, and posterior parts of the hemisphere, from their anterior to their posterior extremity, and from the semi¬ circular margin to a line which extends between these extremities along the lateral borders of the organ. 3. The antero-inferior ox frontal rests on the horizontal part of the frontal and ethmoid bones, commencing before with a curved outline, bounded behind by the curvilinear hollow named the fissure of Sylvius, and at its inner or mesial margin by the great fissure which separates the hemispheres. This inner margin presents one convolution, consisting of a longitudinal eminence, extending in the adult brain about 1^ inch from the posterior towards the anterior end of the notch. The outer furrow contains the cerebral portion of the first pair or olfacient nerves. (1,1.) 4. The medio-inferior or spheno-temporal is situate im¬ mediately behind this region, from which it is separated by the curvilinear hollow (fossa Sylvii). In the ordi¬ nary descriptions this forms the middle lobe; while the 807 posterior part, corresponding to the cerebellum, though dis- Special tinguished by no evident limit, is with equal impropriety Anatomy, named tY\c posterior lobe. I he whole region, from the cur- vilinear hollow to the posterior tip of the hemisphere, may, however, be subdivided into two, the medio-inferior and postero-inferior regions of the convoluted surface, ac¬ cording as they correspond to different containing parts. 5. The posterior cerebellic region of the convoluted sur¬ face, which is plane, corresponds to the horizontal or ce¬ rebellic part of the hard membrane. The convoluted surface is formed of cerebral matter, of a gray or dirty wax colour, the surface of which is smooth and polished where it has not been rent by the removal of the membranes and their attachments. In the fur¬ rows are many minute orifices, into which the soft mem¬ brane (Xsrnj yrpiyZ, meninx tenuis, pia mater) transmits filamentous bodies, containing minute blood-vessels. Neither the eminences nor the hollows are uniform in number or distribution ; and in no two brains is it possible to trace any similarity in their figure, presence, or direc¬ tion, in the upper, lateral, and posterior part of the con¬ voluted surface, unless where it approaches the central or figurate surface, where a number of important objects are presented. The convoluted surface communicates with another interior surface at two parts; ls£, on the middle plane, under the posterior end of the middle band or mesolobe (corpus callosum) ; 2c?, on each side of the middle plane, at the outer margin of the fluted masses termed limbs of the brain (crura cerebri), between these limbs and the posterior end of the optic chamber or couch (thalamus opticus). This surface of the organ may be termed the central or figurate. The exterior surface of the cerebellum consists of thin Laminated portions of cerebral substance named plates (lamince), or surface of leaves (folia), placed contiguously, either parallel or con-d10 cere- centric, and separated by furrows of various depth. Thisbel um‘ surface, which may be named the laminar ox foliated sur¬ face of the small brain, communicates also with the figu¬ rate surface,—ls£, above on the middle plane, between the semilunar notch behind, and the white cerebral plate termed Vieussenian valve before; 2d, at its inferior sur¬ face, between the almonds or spinal lobules above, and the upper end (medulla oblongata) of the spinal chord below. The outline of each hemispherical surface of the cerebel¬ lum describes three fourths of a circle; and as the seg¬ ments mutually meet towards the mesial plane, the mode of union varies according to the figure of the objects to which they are adapted. ls£, The hemispherical border, ap¬ proaching the anterior part of the organ, is suddenly in¬ terrupted where the cerebellic peduncles (crura cei'ebelli) are connected with the protuberance; and, pursuing a retrograde direction on each side towards the mesial plane, forms a re-entrant curvature or notch—the semilunar—Semilunar corresponding to the lower pair of the bigeminous bodies, notch. 2d, The hemispherical borders, approaching the posterior part of the cerebellum, proceed, near the mesial plane, by an acute circular turn, almost straight backwards, and form, at the posterior edge of the organ, a deep rect¬ angular notch, H, not unlike the figure of the ancient Purse-like lyre, named the perpendicular fissure of Malacarne, or notch. the purse-like fissure of Reil, and containing the cerebellic vertical portion of the hard membrane (falx cerebelli). Between these two boundaries the cerebellic plates, of which the hemispheres consist, are united in the middle by an interlacement, named suture (raphe), of the cere¬ bellum. A large hollow between the hemispheres, ex¬ tending backwards from the semilunar to the purse-like fissure, is the small valley (vallecida) of Haller. 808 ANATOMY. Special Anatomy, Cerebellic lobes. The ton¬ sils. The flock, The pyra¬ mid, uvu¬ la, and nodule. Central surface. Central band; cor¬ pus callo¬ sum. Each hemispherical surface consists of five lobes; 1. the anterior-upper or quadrilateral; 2. the posterior- upper ; 3. the posterior-lower; 4. the slender,v rarely ex¬ ceeding three lines in breadth ; 5. the two-bellied or biventral; and 6. the central lobe. The first two belong to the upper or flat hemispherical surface ; the next three to the lower or convex hemispherical surface; and the sixth, common to the two hemispheres, is situate on the mesial plane of the upper surface, between the anterior end of the middle line (raphe) and the middle or apex of the semilunar fissure. The biventral lobe is pointed, and its margin concave; and between this margin and the parts of which the valley consists is placed a group of plates, convex and rounded, named the tonsil or tonsils (tonsillce; amygdalce; the spinal lobule of Gordon). In the angular hollow between the biventral lobe and the peduncle (crus) of the small brain, is the flock, a mi¬ nute body, of irregular shape. Each flock consists of six or seven plates (lamince), starting directly from the begin¬ ning of the peduncle, and with the concave margins di¬ rected towards the protuberance. The valley is distinguished into three bodies, the pyra¬ mid, uvula, and nodidus. The first is a group of 20 parallel plates, with a triangular apex, bounded behind by the purse-shaped notch, and before by another cluster of plates called the uvula. The uvula, which is anterior, consists of twelve laminated leaves, is six lines long and four broad, and is smaller than the pyramid, and conical, with its base turned to that body. Lastly, anterior to the uvida, and separated from it by a furrow, is the laminar tubercle (tuberculo laminoso) or nodule, consisting of about ten thin transverse plates, the smallest in the row. The second surface of the brain, in situation interior or central, may be named the Jigurate or symmetrical. In¬ stead of presenting the uniform eminences and hollows which distinguish the convoluted surface, it is moulded into definite shapes, which correspond with each other, as they are situate on opposite sides of the middle plane,— or the parts of which, when situate on this plane, are ex¬ actly symmetrical. The surface formed by these figured objects bounds what are termed the ventricles or cavities of the brain. They cannot justly be termed cavities any more than the hollows between the convolutions, but ought to be viewed as continuations of the exterior or convoluted surface. The central or figurate surface of the brain presents the following objects. The central band, beam, or meso- lobe, a mass of white cerebral matter, uniting both hemi¬ spheres on the mesial plane, with the twainband or vault below ; the hippocampus major on each side; the anterior pyriform eminence or striated body on each side ; the posterior pyriform eminence or optic chamber on each side; the semicircular band on each side; the ergot on each side; the conarium on the mesial plane; the bige- minous eminences on the mesial plane; the valve on the mesial plane; and its pillars on each side. The commutual or dichotomous region of the convo¬ luted surface is terminated below by the upper surface of a white band uniting the two hemispheres. This, which was named by the ancient anatomists the smooth or po¬ lished body (augu riKkoeidis, corpus Iceve), to distinguish it from surfaces formed by a cutting instrument, appears in the form of white fibrous matter, passing transversely be¬ tween the hemispheres, and marked by three longitudinal lines, one on the mesial plane, and one on each side. This is the middle or central band (mesolobe of Chaussier). Near its middle is a bundle of gray lines, which may be traced to the central portion of the hippocampus major. The posterior extremity of this body is rounded, and Spell communicates with the chamber named third or middle Anatibf, ventricle. This surface is continued forward, and forms''-'’^*- the vault or cieling (fornix, Die Zwillingsbinde, the twain- band, Reil). The names of callous body and vault are used, as if they were denominations of different bodies. If they are still retained, it ought to be stated that they are names applied to opposite surfaces of the same object. The relations of the posterior end of the middle band The Un. are as follow. The handle of a scalpel inserted beneath gular it is found to be in the middle ventricle, with the vaultvaul(" above, the conarium or pineal body, and four eminences of the upper surface of the protuberance (corpora bige- mina) below, and a part of each optic chamber on each side. The vault or inferior surface of the band has the shape of an isosceles triangle, with the base behind. Be¬ fore it is incurvated downward as it becomes narrow; and the space between the band and it is occupied by a thin double plate of cerebral matter, separating the two ven¬ tricles, and named the diaphanous partition (septum luci- dum). (s, s, s.) The fornix terminates before, in two bodies named anterior pillars. (Fig. 3, f, f.) The posterior end of the middle band penetrates intoTheh the substance of the hemispheres; but the gray chordscampif already noticed, pursuing their lateral course, are imme-maj°r- diately enveloped in white plates derived from the sides of the vault, and assuming a cylindrical appearance, form, opposite the cerebral limbs, a body with a free Super rounded surface, which bends in a curvilinear direction lateral laterally and downwards, and is the great hippocampus orc™im cylindroid process. (Chaussier.) In observing this cur-catlon vilinear course, it rests on and corresponds, but without adhesion, to the upper margin of the cerebral limb as it issues from the optic chamber; and the surfaces of both parts, though kept in apposition by vascular membrane, are free and unadherent. It forms the great cerebral fis¬ sure of Bichat. The hippocampus, therefore, consists of two parts. The first, which is the gray indented band (le corps godronnee, Vicq-d’Azyr), is an inner or central portion, as thick as a large crow-quill, gray in colour, indented at the free edge, adhering to the cerebral substance by its opposite margin, and connected with the upper surface of the cen¬ tral band. The outer or second part, which is a broad thin plate of white cerebral matter folded over the gray indented band, as a map is rolled over a cylinder of wood, known under the name of the tape or fringe of the hippo¬ campus, is connected with the lower surface of the same central band, or the vault (fornix) of the brain. At the inferior region the communication is effected Inferii by the curvilinear hollow. (Fig. 1, s, s.) This presents, ]s/,latera! cerebral substance, penetrated by numerous holes of ous size, named the white perforated substance (lamina per¬ forata) ; ‘idly, the unconvoluted space; 3c%, the long cere¬ bral band termed the optic tract; and, \thly, the limb of the brain. This body, with that of the opposite side, is covered by a portion of the convoluted surface, the in¬ ner and prominent surface of the medio-inferior or sphe- no-temporal region. The convoluted surface, which covers the anterior end and outer margin of the cerebral limb, when everted, presents the thin white body named the tape or fringe (tcenia) of the hippocampus; and if the portion of con¬ voluted brain next the curvilinear hollow be raised and everted in the same manner, the anterior end of this ob¬ ject, termed the foot (pes hippocampi), comes into view. The fringe of the hippocampus forms, in the natural position of the organ, the outer and lower border of the opening; while the limb of the brain, and the outer fl] tk^er. ‘:cial and lower surface of the optic chamber, form its inner Aifomy. border. When the central surface is exposed by removing the ppm1-central band and the vault and deling of the ventricles, * two pyriforin eminences, an anterior and posterior, 00016' into view. The anterior is ash-coloured or gray, inclin¬ ing to wood-brown, with the round convex extremity be¬ fore, and the small end tapering backwards and outwards, so as to inclose the round end of the posterior eminence. The surface is smooth and convex, consisting of a thin co¬ vering of gray cerebral matter. The interior consists of an admixture of white and gray, so as to form alternate streaks,—a circumstance from which these eminences on each side have been named the striated bodies (corpora striata). At their anterior mesial extremity are two round¬ ed vertical bodies of white cerebral matter, descending from the anterior end of the vault. These are the ante¬ rior pillars, which are thus interposed between the inte¬ rior front of the striated bodies. Sf 'ircu- The posterior and internal margin of the striated bo- 111 ni1, dies is bounded by a gray, hard eminence, about a line broad, stretching with a sinuous or winding direction from its mesial and anterior to its external lateral and posterior margin. This is the semicircular fillet or band (taenia semicircularis, centrum semicirculare geminum). Always firmer than the neighbouring parts, it appears to be the external margin of a gray-coloured stratum or wall of cerebral matter between the anterior and posterior py¬ riform bodies. Connected before and on the outside to the striated body by means of the double semicircular chord (centrum semicirculare geminum, Vieussens), each optic eminence presents four free surfaces—the upper, the inner, the pos¬ terior, and the lower. The upper is gently rounded, convex, and white in colour; its limits are not easily de¬ fined. The outer margin is bounded by the circular band, which even passes anterior to it, so as to form its bound¬ ary in that direction also. Behind, it is less distinctly limited, unless by the appearance of a considerable pro¬ minence, named the posterior tubercle of the optic couch. The inner margin of the upper surface is distinctly mark¬ ed by a small, sharp, gray line, which, beginning insensibly at the anterior part of the body, becomes more distinct as it extends backwards, and ultimately bends towards the median plane. There it unites with a similar elevated line of the opposite optic eminence; and to the point of union is attached a small conical body with a minute point, of a gray colour, and of a shape like that of the pine-apple. Tins is the pineal gland (glandula pinealis, conarium); and the minute linear eminences which form the inner edge of the upper optic surface have been named peduncles of the pineal gland. The inner surface of the optic couch or chamber pre¬ sents the small portion of soft cerebral matter (commissura mollis) which unites it to the similar surface of the oppo¬ site body; and the intermediate space between the inner surfaces of these bodies on each side constitutes the third or middle ventricle (ventriculus tertius). Its posterior edge, however, is terminated by the cerebral limb of that side; and the lower edge meets that of the opposite one, and is connected to it by a portion of brain which forms the lower part of the middle ventricle, and corresponds on the outside to the bridge of Turin (pons Tarini). yi“'ate The posterior surface of the optic chamber is convex eSl and continuous with the unconvoluted space. Its most con¬ vex part presents two oblong roundish eminences, sepa¬ rated by a linear depression, which may be traced down¬ wards with an outward curvature, and forwards about five or six lines, in a broad white band, crossing two fluted masses mutually converging behind at an angle. These VOL. II. Pil and Nicies. S01 om- t; re uiiiird Veficle. SE: ANATOMY. 80i;) eminences are the geniculate bodies (corpus geniculatum Special externum et internum), the outer the largest of the two Anatomy, (fig. 1, g, g); the white bands are the optic tracts or ori-1^^^^'^ gins of the optic nerve, issuing from the geniculate tu¬ bercles (0, t); and the fluted converging masses are the limbs of the brain (crura cerebri). On the inner or mesial side of the geniculate bodies, Bigemi- and separated only by a linear furrow, are the bigemi- nous omi¬ nous eminences, four orbicular elevations, two above and11611068, two below; two on each side of the mesial plane, with an intermediate cruciform furrow. By the ancients, who ex¬ amined chiefly brute animals, the superior and larger pair were named nates (yXovroi), the inferior testes (ruougoi). These eminences occupy the upper surface of the protu¬ berance, and partly that of the limbs of the brain; and while the eminences are situate between the posterior ends of the optic chambers above, the limbs appear to issue from the centre of these chambers below, and the linear furrow marks the point of junction. These bigeminal eminences, however, though occupy-Cerebral ing the superior surface of the protuberance, adhere not valve, everywhere to its substance. (Fig. 3.) The mesial furrow is formed on the upper surface of a thin plate of white cere¬ bral matter, which extends from the level of the pineal peduncles above, to the upper margin of the cerebellum below, like a veil, and is named the cerebral valve (valvula Vieussenii). The lower surface of this is free for about two or three lines broad; and, though applied to a similar surface on the mesial line of the upper region of the protu¬ berance, does not adhere, but forms a canal with the third ventricle above and the fourth below, named the aque¬ duct of Sylvius (iter a tertio ad quartum ventriculum) (i). While the outer halves, therefore, of the eminences ad¬ here to the matter of the protuberance, the inner are at¬ tached to that of the valve, (n, t.) The lower or cerebellic margin of the valve is free, and Pillars of overhangs as it were the fourth or cerebellic ventricle, the valve. On each side, however, is a longitudinal rounded body of white matter, which passes from the lower pair of bigemi- nous eminences (testes) to the cerebellum. These are named the pillars of the valve (columnce valvula; Vieus¬ senii, processus a cerebello ad testes). The fourth or pathe¬ tic nerve (trochlearis) rises partly from the valve, partly from its lateral pillars, and is seen issuing on the sides of the protuberance not larger than a thread. The lower surface of the optic chambers presents with¬ in the convoluted space the limbs of the brain (crura cerebri), two fluted semicylindrical masses, converging backwards, and inclosing by their junction a triangular space, with the apex behind—the intercrural hollow. The inner margin of the limbs presents the origin of the third or oculo-muscular nerves (oculo-motorii) ; about half an inch anterior on the intercrural hollow are the lenticular or pisiform bodies (tubera, v. corpora candicantia), two he¬ mispherical tubercles of white matter; and immediately anterior is the hypophysis or pituitary gland, a broad quad¬ rilateral reddish-gray prominence, with the anterior mar¬ gin rounded, the posterior concave, inclosed before and on the sides by the converging optic tracts and commissure. (p-) The limbs are obliquely crossed at their outer anterior end by the broad part of the optic tracts as they descend from the geniculate bodies. Their posterior convergent extremities are lost in the substance of the annular pro¬ tuberance (pons Varolii, nodus cerebri), a convex rounded white body, with transverse fasciculi separated by linear furrows, (n.) Connected before with the crura or limbs, from which it is separated by transverse sinuous furrows, it is connected on the sides with the cerebellum by short semicylindrical stalks or peduncles (crura cerebelli), and 5 K 810 ANATOMY.

It is marked on the middle by a longitudinal furrow, in which is placed the basilar artery, the united trunk of the vertebrals. Its convexity corresponds to the concavity of the basilar groove of the occipital bone, on which it rests. This eminence may be regarded as the general central point of the cerebral nervous system, with which all the other parts are connected,—with the cere¬ bral hemispheres by the crura cerebri, with the cerebellic hemispheres by the crura cerebelli, with the upper in¬ ternal part of the optic chambers by the bigeminous emi¬ nences, and with the spinal chord by the medulla oblon¬ gata. From its anterior lateral margin the tergeminal or fifth nerve arises ; from the posterior furrow the abducent or sixth nerve ; and from the upper anterior margin of the cerebellic peduncle the eighth or lateral facial. Continuous with and behind the protuberance is the be¬ ginning or bulb of the spinal chord, a part distinguished on the ground of an obsolete hypothesis by the name of me¬ dulla oblongata. Thick and prominent, its surface is mould¬ ed into six oblong-ovoidal eminences, three on each side of the mesial plane ; the pyriform or pyramidal eminences before, the restiform bodies behind, and the olivary emi¬ nences on each side. The pyriform eminences {corpora pyramidalid) are two oblong-oval bodies, broad above, tapering below, sepa¬ rated by a mesial line, and bounded laterally by a furrow separating them from the olivary bodies, occupying the anterior-inferior part of the bulb of the chord, and rest¬ ing on the lower third of the basilar groove. The mesial line terminates above in the foramen caecum of the poste¬ rior furrow of the protuberance, (p.) The olivary {corpora ovata), placed on the outside of the pyramidal bodies, occupying partly the front, partly the side of the bulb, give it a lateral and transverse pro¬ jection. In the intermediate furrow are the initial fila¬ ments of the hypoglossal or middle lingual nerve ; and in the external furrow and sides those of the glosso-pharyn- geal and pneumogastric nerves, (o, o.) The posterior-upper part of the medulla oblongata con¬ sists of two longitudinal cylindrical bodies, stretching between the cerebellic peduncles above and the spinal chord below. These are the chordal processes of Ridley, the restiform or rope-like processes of Morgagni, the py¬ ramidal bodies of Haller, Malacarne, and Reil, and the posterior pyramidal bodies of Ruysch, Prochaska, and Soemmering. Above, where they are connected with the cerebellic peduncles, they are separated by a triangular space with the apex downward, but below by a deep fur¬ row, the calamus scriptorius of the ancients, at the bottom of which, when separated, may be observed white chords proceeding from the process of one side, plaited with those of the other. These decussating fibres, which are confined entirely to the mesial margin of the restiform processes, are believed to establish a crossing connection between the right and left sides of the peduncles and the protuberance. The intermediate cavity is named the fourth ventricle. From the inner surface of the restiform process issue several of the initial filaments of the seventh or auditory nerve. The spinal chord or funicular brain is a cylindrical body occupying the interior of the vertebral canal, from the margin of the occipital hole to the first lumbar verte¬ bra ; large and round on the cervical region, broad on the dorsal, and terminating in a brush-like expansion, deno¬ minated the cauda equina. On its dorsal surface may be seen a slightly depressed line continued from the middle furrow of the restiform bodies, but becoming faint and indistinct in the region of the back. The central or figurate surface is smooth, polished, and possesses a degree of closeness of texture which pre- Spec vents it from being readily abraded. These qualities are Anatc d ascribed by Reil to a thin pellicle, which he terms epithe-K~*~v J lia. Though there is no proof of the existence of the covering, the term may be used to designate the smooth surface of the organ. Of the central surface not only does every division mu¬ tually communicate, but the central surface of the con¬ voluted communicates with that of the laminated part of the organ. The lateral divisions, named ventricles, com¬ municate directly with each other below the vault, the surface of which lies over the thalami; both communicate with the third ventricle, which by the Sylvian aqueduct communicates with the fourth; and the posterior part of the lateral ventricle communicates with the digital cavity and inferior recess. The central surface is covered by a vascular membrane {plexus choroides), continued from the pia mater of the convoluted surface. Between the two surfaces now described is placed the proper matter of the brain, white and brown, which in dif¬ ferent regions of the organ is differently arranged. The convoluted surface consists of a stratum of gray Struct cerebral matter, arranged in the granular form. When indurated by immersion in alcohol or dilute nitric acid, it breaks with a small conchoidal fracture, occasionally un¬ even, and with an uneven granular surface, void of lustre and without fibrous arrangement. The only part of the convoluted surface presenting the latter appearance is the unciform band* uniting the anterior and posterior lobes. (Fig. 5, v.) Within the convoluted surface is contained a large quan¬ tity of white matter, surrounding the figurate surface and its divisions. The section of this, usually named the oval centre of Yieussenius {centrum ovale), shows merely the extent which this occupies in the upper part of the brain, but communicates no information on the intimate struc¬ ture of the organ. In intimate organization the brain may be distinguish¬ ed into four parts; ls£, the brain, containing the striated nucleus; 2d, the cerebellum, containing the moriform body; Sc?, the head or bulb of the chord, containing the moriform body ; and, bth, the annular protuberance as a central point of the whole. The white fibrous matter of the central band, passing into the hemispheres on each side, diverges like the rods of a fan or the rays of a luminous body, and forms an ar¬ rangement denominated by Reil the radiating crown, and which may be regarded as the exterior investment of the striated nucleus, which constitutes the internal substance of the striated bodies and optic chambers. (Fig. 5, c.) The arrangement of white and gray matter in this part is so peculiar, that within the limits of this sketch it is im¬ possible to convey a distinct idea of it. It may be stat¬ ed in general that the fibrous matter of the limbs ex¬ tends from the protuberance through the substance ot the thalamus and part of the striated body; and while in this manner it maintains a connection between the protuberance and the brain above, by means of the ce¬ rebellic peduncles on the sides, and the head of the chord below, it communicates with the cerebellum and spinal chord behind and below. The moriform bodies {corpora dentata, corjpora ciliata, corpora rhomboidea), which consist of white matter inclosed in a brown capsule, and the cerebellic and olivary eminences, are analogous to the striated nucleus of the brain ; and the three may be regarded as the respective centres of each. The annular protuberance, consisting internally of transverse fibres closely interwoven with longitudinal ones, is the general or common centre of the three. ANATOMY. Sjjial The substance of the funicular or vertebral portion con- inijmy- sists almost entirely of white fibrous matter, extending longitudinally from the cranial to the sacral extremity, but bending off laterally at the origins of the spinal nerves in the form of arches. L|ves- The brain is supplied with blood by the internal ca- rotid arteries and the two vertebral arteries, derived from the subclavian. The former, entering the cra¬ nium by the carotic canals, sends a posterior commu¬ nicating branch, inosculating with the principal division of the basilar, and an anterior communicating, which joins the vessel of the opposite side. By these communi¬ cations, the branches of the basilar artery behind, and the carotids before, form an arterial hexagon round the sella Turcica, from which arise two anterior vessels (anteriores cerebri), distributed to the central band, and two lateral (mediae) or Sylvian arteries, distributed to the perforated spot, the Sylvian fissure and striated nucleus. The verte¬ bral, entering by the occipital hole, send branches to the head of the spinal chord, and uniting to form the basilar, supply the protuberance and cerebellum ; then divaricating into posterior cerebral, finally inosculate with the internal carotid to form the arterial hexagon as mentioned. The blood is returned by triangular canals named sinuses, of which there are the superior longitudinal, the inferior longitudinal, the cerebellic (torcular Herophili), the lateral, the circular, the superior petrous, the inferior petrous, and the cavernous. The four latter pairs are small sinuses opening into the lateral, where it emerges from the cranium by the temporo-occipital fissure (foramen lace- rum in base cranii posterius). § 2. THE CEREBRAL INVESTMENTS OR MEMBRANES. The brain is said to be surrounded by three membra¬ nous envelopes, the hard membrane (meninx dura, dura mater), the web-like membrane (tunica arachnoidea), and the soft or thin membrane (meninx tenuis, pia mater). To this arrangement, which has been adopted by almost all writers, there is perhaps no great objection. But it simplifies the subject, without misrepresenting, to refer them to two only; one of which, the hard membrane (meninx dura, ], dura mater), is common to the brain with the inner surface of the scull; the other, the thin membrane (meninx tenuis, griviyt, pia ma¬ ter), is proper to the brain only. They may be distin¬ guished, therefore, by the terms common membrane of the brain and proper membrane of the brain. The arachnoid, again, is a pellucid web common to the cerebral mem¬ branes. ^ ira The first of these, the common or hard cerebral mem- 1111 brane (meninx dura, dura mater), presents two surfaces, an outer or cranial and an inner or cerebral. The outer surface is irregular, filamentous, and vascular, and the substance of which it consists is distinctly fibrous. The fibres, however, do not follow any uniform direction, but are interwoven irregularly. Maceration causes this mem¬ brane to swell and become separated into fibrous threads. It is liberally supplied with blood-vessels, by which it is connected to the inner surface of the scull. No nerves or absorbents have been discovered in it. This outer or cra¬ nial surface of the dura mater is of the nature of perios¬ teum. Its vessels may be traced into the inner table; it contributes to the formation of the cranial bones in the foetus, and their nutrition during life. The inner or cerebral surface of this membrane is smooth, polished, and shining; and, when examined in water, it appears to be formed by a very thin, transpa¬ rent membrane, through which the cranial or outer sur¬ face and the fibrous structure of the hard membrane may 811 be recognised. This pellucid inner membrime, generally Special termed the inner lamina, is the exterior division of the Anatomy, arachnoid membrane. The dura mater is an extensive membrane, lining Vertebral not only the interior surface of the scull, but, in a modi-sheath, fied form, that of the whole vertebral column. The inner surface of each vertebra has a proper periosteum conti¬ nuous with the periosteum of the outer surface ; and from this issues a quantity of filamentous tissue, which penetrates directly a membranous canal, evidently of fibrous structure (theca vertebralis), tough and firm, but more delicate than the cranial dura mater. The dura mater in its course forms sundry prolongations; for in¬ stance, the large crescentic one named the falx, the hori¬ zontal one termed tentorium, and the small crescentic one named falx minor or cerebelli. The thin, soft, or immediate and proper cerebral mem- The pia brane (pia mater, meninx tenuis) presents in like manner mater, two surfaces, a smooth or cranial, which is exterior, and a filamentous or cerebral, which is interior and central. The outer or smooth surface of the thin membrane (pia mater) has a glistening appearance, and is formed by a very thin transparent membrane, exactly similar to that which forms the cerebral surface of the dura mater. This surface, named in the ordinary works the web-like membrane (tunica arachnoidea), is believed to be a sepa¬ rate membrane from the pia mater ; but that which forms the inner or cerebral surface of the dura mater has a claim equally strong to this distinction. The inner or cerebral surface of the proper membrane is filamentous, flocculent, and sends out many angular fila¬ mentous processes, which, by numerous minute arteries and veins, communicate with the convoluted surface of the brain. These processes (tomenta) correspond to the fur¬ rows of the convoluted surface in which they are lodged. In detaching the membrane from this part of the brain, numerous vessels are drawn out of its substance ; and when the membrane is injected these vessels may be seen dis¬ tinctly filled, and communicating with the gray matter of the convoluted surface. The veins of this membrane may be traced to the sinuses. Neither nerves nor absorbents have yet been recognised in it. Bichat considers it to contain much cellular tissue, which, however, is denied by Gordon, who could not recognise it. The difference, how¬ ever, consists merely in name. The pia mateY, indeed, possesses no cellular tissue like the subcutaneous, the submucous, or the subserous. If, however, a portion of the arachnoid be peeled from it by careful management of the forceps and blowpipe, there is found a quantity of loose filamentous matter uniting this tissue to the fine web of the former. The existence of this tissue betw een the pia mater and arachnoid is further demonstrated by the phenomena of serous infiltration. _ ... The pia mater, or proper membrane of the brain, consists DistribA- of two parts, an outer, covering the convoluted surface of tion an the brain, and an inner or central, entering the cavities formed by the inner, central, or figurate surface, and spread over this surface in the form of what has been termed the vascular or choroid web (plexus choroides; tela choroidea). . .... c The continuity of the pia mater or exterior division ot the proper cerebral membrane, with the choroid plexus or interior division, may be demonstrated in the following manner. First, The pia mater may be traced behind and below the posterior extremity of the middle band (eugM. nWouhn, corpus callosum, der balken), where it is continu¬ ous with the transverse web called velum interpositum, and which may be regarded as the first part of the central division. Secondly, From the situation of the velum in- terpositum, it may be traced forwards on both sides of the 812 ANATOMY. Special mesial plane into the lateral ventricles, spread over the Anatomy, surface of the optic thalamus and striated eminence in the form of the vascular web called choroid plexus, the right half of which communicates with the left by means of a similar slip of vascular membrane lying beneath the vault {fornix), and behind the anterior pillars of that body at the spot termed foramen Monroianum. Thirdly, It may be traced over the geniculate bodies and thalami into the pos¬ terior-inferior cornu, or sinuosity of the lateral ventricle, where it covers the great hippocampus. Fourthly, It may be traced at the angle between the cerebellum and medulla ob¬ longata, or what is named the bottom of the fourth ven¬ tricle, where it forms a very minute choroid plexus, seldom noticed by anatomists, but not less distinct, and which may be traced up the fourth ventricle to be connected with the velum interpositum in the middle ventricle, and with the lateral portions of the hippocampus on each side. Each of the divisions of the choroid plexus now enumerated may be shown to be mutually connected, and to form parts of one general membrane, which again constitutes the inner or central division of the membrane of which the pia mater forms the exterior. Each division of the choroid plexus, in like manner, is connected, by means of minute blood¬ vessels, to the portion of the figurate cerebral surface on which it rests; and it appears to sustain vessels as the pia mater does to the convoluted surface. In clear water the choroid plexus may be spread out, like the pia mater, in the shape of a thin semitransparent web, one surface of which is smooth, the other somewhat flocculent, and the substance of which is traversed by nu¬ merous minute vessels. The transparent web, which forms the basis of this membrane, is filamento-vascular; and its smooth free surface, a continuation of the arachnoid mem¬ brane, is smooth, polished, and thin, like silver paper. The arachnoid membrane is common to the dura mater, pia mater, and choroid plexus. It covers the inner surface of the first membrane, to which it communicates its shin¬ ing polished appearance, though the want of subjacent filamentous tissue causes it to adhere so firmly, that it • cannot be readily demonstrated. After covering the free surface of the pia mater, it follows the course of that membrane into the central surface of the brain, and covers the upper or unadherent surface of the several divisions of the choroid plexus. For the demonstration of this fact we must be permitted to refer to Dr Craigie’s Elements of General Anatomy (chap, xxiii. seet. 1), where the reader will find proofs, which the limits of this sketch do not allow us to adduce here. From these it results that the arachnoid membrane pos¬ sesses in arrangement and distribution a great resem¬ blance to the serous membranes. It differs, nevertheless, in its extreme tenuity, in the closeness with which it ad¬ heres to the collateral tissues, and in its slight disposition to albuminous exudation. It appears to contain in its structure less filamentous tissue than the pure serous membranes. The brain is developed from the branches of the internal carotid and vertebral arteries ramified through the vascu¬ lar membrane {pia mater). Formation commences in two orders of vessels mutually directed to each other,—those of the convoluted surface (pia mater), and those of the cen¬ tral {plexus choroides). The central substance of each part is first deposited; and from these points deposition and moulding proceed to the two circumferences of the organ. The surfaces ar6 therefore formed last; and the vessels gradually shrink as the process approaches to completion. SECT. II. THE DISTRIBUTED CHORDS ; THE NERVES. The nerves may be distinguished into classes according to the parts of the brain with which their cerebral ends are connected. On this principle they may be arranged Spe a in the following order. The brain, The limbs, {Olfactory, 1st pair. Optic, 2d pair. Oculo-muscular, 3d pair. 'Trochlear {nervuspatheticus), 4th pair. (Ophthalmic branch. Ana,, Protuberance or its parts, Head of the chord, Spinal chord, Trifacial, 5th pair, Abducent, Auditory, Lateral-facial, ' Glosso-pharyngeal, Pneumogastric, Accessory, Hypoglossal, 1 Sub-occipital. 7 Cervical nerves. 12 Dorsal. 5 Lumbar. < Superior maxillary. (Inferior maxillary. 6th pair. 7 th pair (portio mcUu). 8th pair ( portio dura). 9th pair. 10th pair (nervus vogtis). 11th pair. 12th pair. , The spinal nerves are derived from anterior and poste¬ rior roots separated by the ligamentum denticulatum, a fibrous notched ligament, covered by arachnoid membrane. According to the researches of Charles Bell and Magendie, the anterior roots furnish motive filaments, and the poste¬ rior sensitive. The central connections of most of these nerves have been already mentioned; and their distribut¬ ed connections have been, and will continue to be, inci¬ dentally noticed under the heads of the several organs. It is requisite, however, to notice shortly the relations and general distribution of several nervous chords which per¬ form an important part in the functions of the animal body. These are the pneumogastric, the phrenic, and the great sympathetic or intercostal nerves. The pneumogastric or nervus vagus, the 8th pair of thePneui old nomenclature, the 10th in correct enumeration of thegastn cerebral nerves, rising by various filaments from the fur-nerve| row between the olivary bodies and the restiform, and from the posterior upper surface of the latter, emerges from the cranium with the jugular vein by the temporo- occipital hole. Here, closely united by filamentous tissue to the hypoglossal, spinal, and glosso-pharyngeal, it de¬ scends before the rectus anticus and longus colli on the out¬ side of the carotid artery, though in the sheath with it, and before the subclavian artery on the right side, on the left before the carotid, enters the chest, where it enlarges in size considerably. (Plate XXXI. v, v.) In the chest it passes behind the bronchi in the posterior fold of the pleura, and is closely connected to the oesophagus in the shape of a thin cord. Both trunks, on reaching the car¬ diac end of this tube, pass with it through the diaphrag¬ matic aperture, and are distributed to the stomach. In this course the pneumogastric nerve is divided into five orders of filaments. 1. In the neck it gives branches to the pharynx, and, communicating with the glosso-pharyngeal, forms the pha¬ ryngeal plexus, and furnishes a superior laryngeal branch, an external laryngeal, and an internal laryngeal, the latter chiefly to the intrinsic muscles of the larynx. 2. In the chest it sends off branches, which, communi¬ cating with those of the superior cervical ganglion, are distributed to the heart. 3. In the chest also it gives off the inferior laryngeal or recurrent nerve (r), which on the right side winding round the subclavian, on the left the arch of the aorta, re¬ ascends in the lateral furrow between the windpipe and oesophagus, and giving off cardiac, pulmonary, oesophageal, thyroid, and tracheal filaments, is finally distributed to the intrinsic muscles of the laryngeal cartilages. These multi¬ plied connections tend to associate the motions of the glottis with the lungs, and to maintain a general consent between the pharynx, larynx, oesophagus, trachea, lungs, and heart. ANATOMY. 813 phre- niiirve. Threat ijt athe. tii. ikial 4. The pneumogastrlc trunk forms with the filaments of A omy. the inferior cervical ganglion the anterior pulmonary plex- ^ us, and alone it forms the posterior pulmonary plexus, which sends filaments to the lower part of the windpipe, the bronchi, the pulmonary artery and veins, and the oeso¬ phagus. 5. After passing the diaphragmatic aperture, the right pneumogastric trunk forms at the cardiac orifice of the stomach a plexus, from which filaments proceed to the pylorus, the gastro-hepatic artery, the right cceliac gang¬ lion, the duodenum, the pancreas, the gall-bladder, and the liver, where it communicates freely with the cceliac ganglions. The pneumogastric of the left side is distri¬ buted chiefly to the pylorus and its arteries, and commu¬ nicates freely with those of the right. The phrenic or diaphragmatic nerve, connected above with filaments of the pneumogastric, hypoglossal, second and third cervical nerves, and some branches of the bra¬ chial plexus, and occasionally with those of the great sym¬ pathetic, descends on the anterior and lateral part of the neck, between the rectus anticus and scalenus anticus, and enters the chest between the subclavian artery and vein. The right passes down on the surface of the right lung, beneath the pleura (p, p, Plate XXXI.); the left over the pericardium; and both are distributed chiefly to the dia¬ phragm. The great sympathetic is much more complicated than either of these nerves. It cannot be said to originate sj chnic ^rom 0116 Part more ^lan from another. Though connected with the brain by means of a communicating filament of the sixth pair, it certainly does not arise from that nerve : nor can it be said to arise from the spinal nerves, though connected with them on each side of the dorsal vertebrae. It appears more rational to regard it as a general and ex¬ tensive network of nervous filaments, which establish a communication between different important organs. Con¬ nected above with three ganglions of the neck, the supe¬ rior, inferior, and middle cervical, and by minute filaments with the lateral-facial, or eighth cerebral, pneumogas¬ tric, and glosso-pharyngeal, with which it contributes to form the pharyngeal plexus, it sends off the nervi molles or superficial cardiac nerve. Below the inferior cervical gang¬ lion, generally regarded as a cardiac, the trunk enlarges, and furnishes filaments to the pulmonary and cardiac plexus, the former divided into right or anterior and left or posterior, and the latter into superior and inferior. About the seventh dorsal vertebra, after being connected with all the intercostal nerves and inferior thoracic gang¬ lions, it forms the splanchnic, which, though only the abdo¬ minal part of the great sympathetic, may be regarded as a separate nerve. The constituent filaments of this nerve, af¬ ter being united into two ganglions, the coeliac or semilunar, are resolved into plexiform arrangements, which surround all the principal arteries, and with them are lost in the sub¬ stance of the organs. Thus the cceliac artery is inclosed by the cceliac plexus; and each of its divisions, the coro¬ nary or proper gastric and the gastro-hepatic and gastro- splenic, are inclosed in similar plexiform networks. In the same manner, the superior mesenteric, inferior mesente¬ ric, and renal arteries, have each an appropriate plexus ; and those of the colon, bladder, and uterus have small plexiform arrangements, which constitute parts of the same general system. In short, the great sympathetic or intercostal forms an independent nervous system of its own, and though not derived from the dorsal nerves, is intimately connected with them; and its distribution to the organs of digestion, of circulation, respiration, and se¬ cretion, is connected chiefly with the associated actions of these organs. Our limits do not, however, admit of details; and the reader who wishes to understand the minute anatomical Special relations of these chords, will find tiie most accurate in- Anatomy, formation in the fourth volume of the treatise of Soem-^v^^ (. CorporisHumani Fabrica, Trajecti ad Mcenum 1798) ; in the third of the Descriptive System of Bichat? and in the magnificent illustrations of Walter (Tabula Nervorum Thoracis et Abdominis, fol. Berolini, 1783) and Scarpa ( Tabulae Neurologicae, fol. Ticini, 1794). PART II. ANATOMY OF THE ORGANS PERTAINING TO THE ENTRO- PHIC OR NUTRITIVE FUNCTIONS. The growth of the animal body is effected, and its size and strength maintained, by a class of organs which may be named the Entrophic or Nutritive. These organs agree in the possession of certain common characters, by which they are distinguished from those of the functions of Relation. The first common character is the want of symmetry in arrangement and harmony in action. Instead of being arranged on the median line, or with similar parts on each of its sides, the organ, or part of the organ, which is on one side, bears no resemblance to that which is on the other. Even in the case of the lungs, though there is a general resemblance, the left differs from the right not only in size and shape, but in the number of its lobes. It must not be understood, nevertheless, that the or¬ gans of this class are altogether void of symmetrical figure. A plane may be made to divide the stomach even into similar halves, so as to leave on each side similar parts of the cardia, of the pylorus, and of the intermediate parts. This plane, however, corresponds not with the mesial plane, but passes transversely from left to right. Nearly the same rule is applicable to other organs. The second general character of the entrophic organs is, that in action they are not under the influence of the will. The contractions of the muscular tissue of the stomach, and the secretion of its mucous surface, the pe¬ ristaltic motion of the intestinal tube, the beats of the heart, and the action of the liver, are equally independent of volition. This character Bichat attempted in every instance to trace to independence on the influence of the brain and the cerebral nerves. In one sense this is a truism, in so far as it merely implies that the organs of the entrophic functions do not belong to those of relation. In another sense it is a gratuitous, if not a hypothetical assumption. Though the brain is evidently very inti¬ mately associated with the organs of the animal functions, it is not yet determined that it is entirely unconnected with those of the entrophic order. Serious lesion or in¬ jury of the brain or the protuberance operates as forcibly on the action of the heart as on that of the muscles of the extremities. On the whole, the safest mode of de¬ fining this character is merely to state the independence of the entrophic organs on the will. Several of the organs of the entrophic function are nevertheless in some degree under the influence of the will. The lungs, for example, by being dilated only by the dilating agents of the chest, are within certain limits under the voluntary power. To this, however, a limit is fixed. Though inspiration or expiration may be effected at the will of the individual, or suspended for a little, very soon the accomplishment of these actions is no longer arbitrary. In like manner, though the bladder is evacu¬ ated by the voluntary effort of the individual, the stimu¬ lus by which the action is induced is involuntary alto¬ gether. A third anatomical character common to the entrophic organs is, that all of them are situate in the interior of the 814 ANATOMY. Special trunk, protected by those of the locomotive system ; and Anatomy, that they are lined on one side by mucous membrane, continuous with the external integuments. By means of this arrangement, which is necessarily allied with their property of converting foreign into proper matter, all the entrophic organs, with the exception of the heart, com¬ municate with the surface of the body. A fourth anatomical character common to these organs is, that though continuous by their mucous investment with the outer surface of the body, their opposite, placed on the outside of the serous membranes, forms shut cavi¬ ties, not communicating, unless in one instance—the peri¬ toneal end of the oviduct in the female—with the external surface. Whatever be the intermediate substance, these organs are placed between the mucous and serous mem¬ branes. The entrophic organs may be distinguished into two orders, according to the degree of the process performed by each. The nutritive function consists of two subor¬ dinate functions, the Umitrophic or alimentary, and the hcematrophic or circulatory; the first the preparation of the materials destined to be employed in nutrition ; the second the distribution of these, after preparation, to the different regions and organs of the system. The organs by which the first process is accomplished constitute the first order; those by which the second is effected constitute the second order. CHAP. I. THE LIMITROPHIC ORGAN'S. The limitrophic organs consist of two divisions ; those for digestion of the food, or the chylopoietic, and those for absorption of its nutritious part. The former is ef¬ fected in successive processes in the divisions of the ali¬ mentary canal, a tubular musculo-membranous apparatus, extending from the mouth to the anus. The second is accomplished by an assemblage of minute valvular tubes, the lacteals, terminating in the thoracic duct. SECT. I. THE ORGANS OF DIGESTION; THE CHYLOPOIETIC ORGANS. The organs of mastication have been described already in the fourth section of the second chapter of Part First. The pha- The pharynx, placed on the median line, symmetrical rvnx. and regular, occupying the upper part of the neck, makes a close approach to the organs of relation, and marks the transition from these to those of the entrophic function. Attached above to the cuneiform process of the occipital bone, behind to the cervical vertebra;, and with the nostrils, mouth, and larynx before, it forms an irregular vaulted apartment about four inches long and two broad at its widest part, and contracting below, where it is continuous with the oesophagus. Besides the opening into this tube, the pharynx presents six apertures; the pharyngeal aper¬ tures of the nostrils, the pharyngeal orifice of the mouth, the upper end of the larynx, and the pharyngeal aper¬ tures of the Eustachian tube. It consists of a mucous membrane stretched over loose filamentous tissue inclosed by three muscles, the superior, inferior, and middle constrictor, and attached to the cunei¬ form process, the cervical vertebrae, and the lateral regions of the neck, by filamentous tissue. By the superior laryngeal, the pharyngeal, the thyroid, the lingual, and palatine arteries, it receives blood, which is returned by a still greater number of veins to the exter¬ nal and internal jugular trunks. The nerves of the pharynx come from the glosso-pharyngeal, the hypoglossal, the pneumogastric, and the great sympathetic. The ceso- The (esophagus(gula) is a cylindrical musculo-membran- phagus. ous tube, communicating above with the pharynx, and below with the stomach. Placed above between the Spetlj cervical vertebrae behind and the windpipe before, at the Anati jy, lower end of the larynx it inclines to the left, returns to^^^ ^ the median line at the sternum, bends again to the left at the bifurcation of the trachea, and continues on the left side of the line, passing the aperture of the diaphragm, near the ninth dorsal vertebra, to its junction with the stomach. With the vertebral column behind, at its first inclination it covers the longus colli in the chest, crosses the vena azygos above, and covers the thoracic duct in the middle, and the aorta below. With the jugular veins and carotids on each side in the neck, below it has the trachea on the right, and the recurrent nerve and common carotid on the left; and in the chest it has the aorta on the left and behind. (Plate XXIX. fig. 2, c.) Lined on the inside by a follicular mucous membrane which assumes longitudinal folds (plicae), the oesopha¬ gus consists of two ranges of muscular fibres, the one transverse, the other longitudinal. The first are most distinct at the pharyngeal end. The second form a mani¬ fest thick layer through the whole extent of the tube. Externally is a quantity of filamentous tissue, connecting the tube to that of the mediastinum and adjoining parts. The oesophagus is supplied with blood from the inferior thyroid, thymic, laryngeal, pharyngeal; the aorta by pro¬ per oesophageal arteries, the superior intercostals and bronchials, the pericardial, mediastinal, diaphragmatics, and even the coronary of the stomach. The blood is returned by veins equally numerous. The oesophageal nerves proceed from three different sources. Above, it receives filaments from the glosso-pharyngeal and pneu¬ mogastric, in the middle from the latter, and below from the pneumogastric and the great sympathetic. The stomach (ventriculus) is a large pyriform musculo-The s membranous sac, incurvated on itself (Plate XXIX. fig. 2, mach. and Plate XXXVI. fig. 4), situate in the epigastric and left hypochondriac regions, communicating above with theceso- phagus, and below with the duodenum. Bounded above by the diaphragm, and the liver, which covers it, it has the spleen attached to its left great extremity, the transverse arch of the colon to the inferior large arch; and its posterior surface corresponds to the duodenum, pancreas, mesoco¬ lon, and large abdominal vessels. The pyriform sac of the stomach is distinguished into a large end or sac (fundus), and a small extremity named the pyloric ; while a particular incurvation of its direction gives it a large inferior arch (arcus major), and a small superior arch (arcus minor). At the left extremity of the latter is the cardia, the orifice by which the (Esopha¬ gus enters the stomach (osteum cesophageum) ; and from this round the fundus is the large arch. A vertical plane drawn from the cardia divides the stomach into two por¬ tions,—-the cardiac (fundus, saccus ccecus), and pyloric, terminating in an annular contracted opening, about an inch broad (pylorus, ostium duodenale sive pyloricum). Between the two arches is the superior-anterior surface, covered partly by the left lobe of the liver, partly by the left rectus and hypochondre, and the inferior-posterior sur¬ face behind. The stomach consists of peritoneum externally, mucous Strut membrane internally, and an intermediate muscular layer with filamentous tissue. The peritoneal covering is arranged in a peculiar man¬ ner. The anterior fold, meeting the posterior at the small arch, joins it, and forms a membranous production (omentum gastro-hepaticum), connecting the organ to thi inferior surface of the liver, where they again separate tc invest the upper and lower divisions of that organ. I best folds, meeting in like manner along the large arch, when they form similar duplicatures, are again separated to in •e. ANATOMY. 815 i I'cial close the spleen at the large end, and the colon along the 4 omy. lower division. In the triangular spaces formed by these ^''-^duplicatures the gastric blood-vessels are lodged. The mucous membrane, void of epidermis, is covered with minute piles (villi) from the cardiac, where they commence at the fringed termination of the oesophageal epidermis, to the pyloric, where they are continuous with i those of the duodenum. It is further puckered into wrinkles (rugai) or folds (plica), intersecting each other i irregularly, and inclosing irregular quadrilateral spaces,— an effect produced by the contraction of the muscular coat, and connected with the great extent of the gastric villous membrane. In this also are contained follicular glands, especially at the pyloric end and along the two curvatures. The muscular coat consists of two ranges of fibres, one longitudinal, following the great diameter from the cardia to the pyloric end; the other circular internal, inclosing the circumference of the organ, and most distinct when the organ is empty. On the latter depends the contracted in¬ curvation of the stomach between the cardiac and pyloric divisions. (Plate XXXVI. fig. 4.) Besides these, there are on the left side of the cardia muscular slips expanded on the two surfaces. (lie The stomach derives its blood from the cceliac artery, war the branches of which are arranged in a peculiar and MP' beautiful manner. The cceliac divides into three vessels ; one gastric proper, the coronary; one common to it and the liver, the gastro-hepatic; and one common to it and the spleen, the gastro-splenic. The first, the coronary, is distributed to the cardiac end, and, lodged in the peri¬ toneal fold of the small arch, proceeds towards the pylo¬ rus, distributing branches before and behind. The se¬ cond, after sending a large vessel to the liver, the hepatic, sends a small one (arteria pylorica), from the pyloric end, towards the gastric, by the superior peritoneal fold, to meet the terminal branches of the coronary; and a large one i (gastro-epiploica dextra), by that of the large curvature, to meet the terminal branches of the left gastro-epiploic. The third or spleno-gastric artery, after transmitting a large vessel to the spleen, and various small vessels (vasa brevia) to the large fundus, sends a large vessel (gastro- epiploica sinistra), in the peritoneal fold of the large arch, to inosculate with the terminal branches of the right gastro-epiploic. The stomach is in this manner em¬ braced, as it were, by arterial canals above and below. It is further remarkable, that while only one proper gas¬ tric artery, of inconsiderable size and limited distribution, proceeds from the coeliac trunk, the gastro-hepatic and gastro-splenic, each not much less than the coeliac itself, send their largest branches to the stomach, and proceed¬ ing from opposite ends of that organ, inclose it, meeting by inosculation in the middle of its great and small curvatures. From the capillaries at the fundus, chiefly the vasa brevia, the gastric fluid appears to be secreted. The blood, re¬ turned by corresponding veins, is poured into the portal. The stomach receives nerves from the pneumogastric and the great sympathetic. In the stomach the aliment- J. ary mass is converted into the pulp named chyme. ^u°- The duodenum (ventriculus succenturiatus), about twelve 1 '■ inches long in the human subject, is distinguished by being the most fixed part of the tube in situation. Placed on the vertebral column, and on each side in the cavity of the •mesocolon, behind the stomach, and concealed by that organ, it is bounded above by the liver and gall¬ bladder, below by the pancreas and lower part ot the mesocolon, and maintains the communication with the pyloric end of the stomach and the ileum. The duodenum is divided by two curvatures into three portions. I he first, which is covered by peritoneum, extending from the pylorus to the site of the neck of the gall-bladder, hori- Special zontally backwards and a little to the right, descends Anatomy, about two inches almost perpendicularly. With this the^-^^^ second portion, forming an angle, ascends obliquely to the left, and terminates opposite the third lumbar vertebra. The third, forming an angle rather more than right, ex¬ tends about two or three inches, and terminates at the peritoneal ring, about one inch on the left of the spine, where the ileum commences. The aperture of the com¬ mon biliary duct, inclosed in a nipple-like process, and the pancreatic, are in the first portion. These curvatures are firmly connected by filamentous tissue; and the bowel retains them even after removal from the body. The duodenum, void of peritoneal covering, consists externally of cellular tissue, inclosing a range of circular muscular fibres, and lined by villo-mucous membrane, ar¬ ranged in numerous folds, or valvulce conniventes. The duodenal arteries are derived chiefly from the gastro-he¬ patic, and are very generally pyloric twigs. This mem¬ brane is provided with follicles, first well described by Brunner. In the duodenum, by admixture of the biliary and pan¬ creatic fluids with the chyme, the latter is prepared for the separation of chyle, which, though more proper to the ileum, is begun nevertheless in this bowel. The comparative im¬ mobility of the bowel is requisite, both in consequence of the admixture now mentioned, and also of the fixed situa¬ tion of the two glands by which the fluids are supplied. The ileum (u'Km) or small intestine (intestinum tenue). The ileum, the longest part of the intestinal tube, extending generally from 28 to 30 feet, commences at the annular process above mentioned, and extends to the head of the colon, in which it opens in the right iliac region. It consists of a cylindrical musculo-membranous tube, surrounded by peritoneum, the two folds of which, meeting behind, at¬ tach it for the space of three or four inches to the ver¬ tebral column, and are again reflected laterally, as de¬ scribed in the first book of this treatise. This attaching membrane is named the mesentery. The great length of the tube, with the small extent of the mesentery, causes it to hang suspended in numerous turns or convolutions. By the ancients this intestine was distinguished into two parts, jejunum or the empty, and the ileum proper; and Winslow idly undertook to fix the limits of this division by referring the two upper thirds to the former, and the two lower to the latter. This distinction, however, for which there is no anatomical foundation, must be rejected as at once arbitrary and useless. The muscular tunic consists of circular fibres entirely. The villo-mucous membrane presents numerous valvulce Structure. conniventes, which increase its surface to at least double that of its proper area. These duplicatures are most nu¬ merous in the upper part of the tube, and diminish as they descend. The mucous surface of the ileum is peculiar in pre-The villi, senting the piles or villosities in their most perfect form. When a portion of ileum is inverted, inflated, and immers¬ ed in pure water, an infinite number ot minute processes are seen waving amidst the fluid; but a powerful glass does not enable the observer to determine whether they are round or flat, solid or hollow, obtuse or pointed. Of their shape and structure various accounts are given. They were first represented, in 1721, by Helvetius, as cylindrical prominences in quadrupeds, but conical in the human subject. According to the microscopical observa¬ tions of Lieberkuhn, each villus receives a minute lac¬ teal tube, arterial branches, a vein, and a nerve; and in each the lacteal is expanded into a minute sac or blad¬ der (arnpullula, vesicula) like an egg, in the apex of which may be seen by the microscope a minute opening. 816 ANATOMY. The villi. Special On this sac the arterial branches are ramified to great Anatomy, delicacy, and terminate in minute veins, which then unite into one trunk; while its inner surface he represents as spongy and cellular. The space between the villi, which do not touch each other, he further represents to be oc¬ cupied by the open orifices of follicles, so numerous that he counted eighty of them where were eighteen villi; and both, he asserts, are covered by a thin but tenacious membrane similar to epidermis. Hewson, while he admits in each villus the ramification of minute arteries and veins, denies the saccular expan¬ sion, and infers that the lacteals are ramified in the same manner as the blood-vessels, and that the whole consti¬ tute a broad flat body, the spongy appearance of which he ascribes to the mutual ramification of the latter. With this in general Cruikshank agrees; while Sheldon, who found the villi not only round and cylindrical as Hewson, but bulbous as Lieberkuhn, and even sabre-shaped, rather confirms the statements of that anatomist. Mascagni and Soemmering, agreeing in the general fact of vascular and lacteal structure, seem to represent the shape of the villus as that of a mushroom, consisting of a stalk and a pileus. Some of these discordant statements Hedwig attempts with equal ingenuity and industry to reconcile. The dif¬ ferences in shape he refers to differences in the animals examined; and in one class finds them cylindrical (e. g. in man and the horse) ; in another conical (the dog) ; in a third club-shaped (the pheasant); and in a fourth pointed or pyramidal (e. g. the mouse). The interior structure he also represents as spongy in all the animals which he examined; and invariably also he found at the apex the orifice of the duct, which, after the example of Lieberkuhn, he conceives constitutes the ampullula. These conclusions are not exactly confirmed by the re¬ searches of Rudolphi, who examined the villi in man and a considerable number of animals. This anatomist never found the orifice seen by Hedwig, notwithstanding every care taken to distinguish it. He maintains that the villi are not alike in all parts of the intestinal canal of the same animal, as represented by Hedwig, but may be cylindri¬ cal in one part, club-shaped in another, and acuminated in a third. Admitting their vascular structure, which he thinks may be demonstrated, he regards the ampullular expansion as doubtful, and denies its cellular arrangement. About the same time Bleuland, who had previously ex¬ amined the intestinal mucous membrane, after successful injection of its capillaries, undertook to revive the leading circumstances of the description of Lieberkuhn. By ex¬ amining microscopically well-injected portions of intes¬ tine, he shows that the villi are composed of a system of very minute arterial and venous capillaries, inclosing a lacteal, which constitutes the ampulla, and in the interior of which a certain order of these capillaries terminates. He also revives the statement of the absorbing orifice at the extremity of each villus. According to the observations of Beclard, the intestinal villi appear neither conical, nor cylindrical, nor tubular, nor expanded at top, as described by several authors, but in the shape of leaflets or minute plates, so closely set that they form an abundant tufted pile. Their shape va¬ ries according to the manner in which they are examined, and according to the part. Those of the pyloric half of the stomach and duodenum are broader than long, and form minute plates; those of the jejunum are long and narrow, constituting piles; at the end of the ileum they become laminar, and in the colon are scarcely prominent. They are semitranslucent; their surface is smooth; and neither openings at their surface, in their cavity, or in their interior, nor vascular structure can be recognised. on The villo-mucous membrane of the ileum is provided Sp|; with mucous follicles of two orders, the glandulce solita- An rice and the glandules agminatce; the former, like gran-^ ules, disseminated over the attached surface of the muAe^' cous membrane; the latter clustered in bodies at the an- ant terior exterior part. They partake of the general charac¬ ters of follicular structure. The ileum is liberally supplied with blood by the supe¬ rior mesenteric artery, the arrangement and distribution of which may be understood from fig. 4, Plate XXIX. The nerves are derived from the solar plexus. The colon, or large intestine (jntestinum crassum), be-The ginning in the right iliac region, extends round the folds of the abdominal cavity, inclosing the Ileum, to the left iliac and pelvic, where it terminates in the rectum. Its length is from six to seven feet. The beginning (caput ccecum) is a round obtuse bowel, with a minute tubular process, varying in length, named the vermiform. The lower end of the ileum is inserted into the beginning of the colon laterally; and to the part below the inser¬ tion the name of caecum or blind gut is restricted. From the ccecum the colon descends to the right hypochondre (colon dextrum), where it is connected at the hepatic flexure to the liver by the hepato-colic ligament, two folds of peritoneum, with intermediate filamentous tis¬ sue ; between the right or hepatic flexure and the left or splenic it is distinguished as the transverse arch (colon transversum), attached to the large arch of the stomach by the gastro-colic margin of the omentum; an angular bend in the left hypochondre forms the splenic flexure; and, finally, after making a long sinuous alternating bend in the left iliac and pelvic regions, named the sigmoid flexure, it terminates in a portion comparatively straight (ro rectum), and following only the antero-posterior incurvation of the inner surface of the sacrum, on which it is placed. The colon is about two inches in diameter at an average. The appearance of this intestine is intimately connected with its structure. Inclosed in peritoneum, by the poste¬ rior junction of which it is connected to the adjoining or¬ gans, it consists of a layer of circular fibres, intersected by three bands of longitudinal fibres. Both are asserted to be muscular; but perhaps the latter are more of the nature of aponeurosis, to give support and resistance to the action of the former. Whatever be their nature, how¬ ever, they give the colon the appearance of being divided into transverse cells, separated by superficial partitions. The mucous membrane of the colon possesses the villous character in the caecum and right part, but loses it towards the lower part of the intestine. It is formed into large transverse folds or duplicatures, which separate the inter¬ nal cells or compartments of the bowel. At the insertion of the ileum into the colon the mucous The jo- membrane of each is prolonged with the submucous tis-^j^ sue, and they mutually meet in two crescentic processes, one superior, small (plica superior, labium superius), the other inferior, large (plica inferior, labium inferius), and approaching, by its greater prolongation, the paraboloid shape. The ileal side of both folds is concave, the caecal or colic convex; and between their free margins, which are rounded, is an intermediate fissure, maintaining the communication between the two intestines. This arrange¬ ment, which is named the ileo-caecal valve (valvula Bau- hini, from its supposed discoverer), is supposed to allow the transit of alimentary and excremental matter from the ileum to the colon, but not in the converse direction. The organization of the rectum is the same as that of the colon generally; but it is uncovered by peritoneum behind. Its lower extremity is surrounded by two circu¬ lar ranges of muscular fibres, named the internal and ex- ANATOMY. rial ternal sphincters.. The lower fibres of the levator ani are omy. inserted into its sides. ^ The caecum and right and transverse portions of the co- llar Ion are supplied with blood from the superior mesenteric, n' by means of the colic arteries. The left iliac or sigmoid flexure receives vessels from the inferior mesenteric. The splenic part is supplied by vessels derived from the great anastomotic communication between the superior and inferior mesenteries. (Plate XXIX. fig. 4.) The rec¬ tum is copiously supplied with blood from three different sources. The first is the termination of the inferior me¬ senteric, which is contained between the folds of the me- sorectum, under the name of superior hemorrhoidal. The second is the middle hemorrhoidal, or proper artery, derived from the hypogastric or posterior iliac. The third is the internalpudic, the lower or perineal branch of which sup¬ plies the sphincter with several branches on each side, dis¬ tinguished by the name of inferior hemorrhoidal arteries. The nerves are derived partly from the hypogastric plexus, partly from the sacral branches. The rectum, like the pharynx, placed between the two classes of organs, entrophic and animal, belongs in some degree to both. As the termination of the alimentary ca¬ nal, it belongs to the former; but by its sphincters and kvator it pertains to the latter. The appendages of the alimentary canal are two glands, the liver and pancreas, and a cellulo-vascular organ, the spleen. ver. The liver (Jiepar,jecur) is a large glandular organ, weigh¬ ing from two to three pounds, situate in the right hypo¬ chondriac and epigastric regions, with the diaphragm above, and the hepatic flexure of the colon and the stomach be¬ low. It has a convex upper surface, a concave lower one, a posterior obtuse margin attached to the diaphragm by cellular tissue, and an anterior inferior acute one which is free. The lower surface is distinguished into right and left lobes by a middle pit {sulcus umbilicalis, v. hori- zontalis'), in which the round ligament, the residue of the umbilical vein, is contained, and which is occasionally a canal by an arch of hepatic substance. The inferior sur¬ face of the left lobe is divided into anterior and posterior parts by a transverse furrow (sidcus transversus, fossa transversa), in which the trunk of the hepatic arteries, and the portal vein, and the hepatic ends of the biliary ducts, are contained. The margins of this furrow, which are elevated in the lower animals, were named gates by the ancients (nvXai, portce), from an erroneous theory. The posterior, which is most prominent, is distinguished by the name of small lobe of Spigelius (lobulus Spigelii). The other distinctions of this surface into lobulus qua- dratus and lobulus caudatus are immaterial. Between the anterior portal eminence and the umbilical fossa is an oval depression (fovea cystica), containing the gall bladder. The liver is invested by peritoneum, the folds of which connect it to the neighbouring organs, and retain it in its place. Of these, the most important are the broad and coronary above, the lower or falciform below, and the gas- tro-hepatic duplicature between the liver and stomach. This forms the investment named capsule of Glisson, in which the portal veins are inclosed. j|re The structure of the liver is glandular. Two classes of ani.vessels and a system of tubes are distributed in it; one ramifying into branches and minute tubes, the hepatic artery and portal vein; another, the hepatic veins, con¬ verging to a trunk, the vena cava hepatica ; the third, the pori bUiarii, converging into ducts terminating in the he¬ patic duct. From the researches of numerous anatomists, it appears that the hepatic artery, which is derived from the cceliac, and the portal vein, formed from the veins of the stomach, intestines, spleen, and pancreas, terminate VOL. II. in minute vessels mutually communicating, further, that these capillaries 817 It appears Special , . communicate with those Anatomy, ot the hepatic veins, and even the origins of the biliary pores; and Soemmering especially infers, that every he¬ patic acinus consists of hepatic artery, portal vein, hepatic vein, bile-pore, and lymphatic. From this, however, it does not altogether result that bile is secreted from the hepatic arterial blood. Each acinus may require a minute artery for nutrition, a portal venule for furnishing the materials of secretion, a duct for receiving the secreted product, and a vein for returning the residual blood. The hepatic duct unites at an angle with the cystic, and forming the common duct, terminates in the duodenum. The gall bladder, which is a pyriform bag, with X\\^ fundus below and before, and a neck above and behind, acts as a receptacle for the bile when it is not required in the duodenum. The fundus, placed between the concave sur¬ face of the liver above, and the convex one of the pyloric division of the stomach below, may be compressed by that part of the organ when distended, so as to expel the bile from its cavity. The pancreas is a flat, oblong, glandular body, measur-Tlie pan- ing from five to six inches in length, and weighing fromcreas. three to five ounces, contained in the posterior epiploic cavity below the duodenum. It consists of lobules similar to those of the salivary glands. It has a proper artery, from which the pancreatic fluid, very similar to the salivary, is secreted, and conveyed into a small duct. The residual blood is conveyed by a proper vein to the portal. The spleen (lien) is an oblong hemispheroidal organ, ofThespleen. a deep blue venous blood colour, varying in weight from 6 to 12 or 15 ounces, placed in the left hypochondre, between the fundus of the stomach and the left side of the dia¬ phragm, with a plane surface applied to the former, and a convex to the latter part. The spleen is covered by peri¬ toneum, which, doubling before, forms along the middle of the organ a gastro-splenic omentum, by which it is attach¬ ed to the stomach. It is generally connected to the colon by a short peritoneal slip. The intimate structure of the spleen is peculiar. It consists of a number of minute communicating compart¬ ments, separated by septa, with white granules intermixed. These cells contain dark-coloured blood; and the organ is indeed more abundantly filled with this fluid than any other in the body. These cells appear to be of the na¬ ture of erectile vessels. The splenic artery is very large in proportion to the organ, and apparently communicates by minute terminations with veins, in which the blood is occasionally accumulated. The principal use of the spleen appears to be, that it serves as a receptacle for a large quantity of blood, which accumulates in the splenic vessels, or flows into those of the stomach, as the latter organ requires. When the stomach is empty, it shrinks ; and its blood-vessels, folded on themselves, neither require nor transmit so much of this fluid as they do when the organ is distended. In the latter case the vessels are stretched, their canals are rectified, and the blood flows freely through them. At this period the additional supply seems chiefly to be de¬ rived from the spleen. The splenic vessels also appear to contribute chiefly to the secretion of the gastric fluid, which is most abundant at the fundus of the organ. SECT. II. THE CHYLOPHOROUS VESSELS. On the lacteals or intestinal lymphatics it is superfluous to add any thing to what is stated in Book I. These vessels arise from the villous surface of the ileum, and proceeding between the folds of the mesentery, unite at the vertebral margin of that membranous duplicature, somewhere between the third lumbar vertebra and the aor- 5 L 818 ANATOM Y. Special tic opening of the diaphragm. Here they terminate in a Anatomy, jointed irregular tube situate behind the aorta, and which, passing through the aortic opening of the diaphragm, pro¬ ceeds through the chest between the artery and vena azy¬ gos, as high as the sixth, fifth, or fourth dorsal vertebra. Here it inclines to the left, and, passing behind the aortic arch and the left subclavian artery, winds to the left of the latter vessel, and, before the longus colli, ascends as high as the seventh or sixth cervical vertebra, where it termi¬ nates in the angle between the internal jugular and sub¬ clavian veins, in the trunk of these vessels. This is the thoracic duct. A similar vessel, though smaller, is found on the right side. CHAP. II. THE HEMATROPHIC ORGANS. The organs of the hematrophic or circulating function consist of the heart as a central propelling agent, and of arteries and veins as distributing and redycent ^channels. The hematrophic organs may be distinguished into three orders; first, those of the general or nutritive circulat¬ ing system; secondly, those of the aerating circulating system; and, thirdly, those of the secreting system. Of these the heart is the central agent; but in the mammalia and man it consists of two divisions, one pertaining to the general arterial, the other to the pulmonary or aerating system. SECT. I. THE ORGANS OF NUTRITIVE CIRCULATION. § 1. THE HEART AND HEART-PURSE. The heart is a conical muscular organ, containing four communicating chambers, inclosed in a membranous sac, and situate in the anterior middle region of the thorax. The peri- The inclosing sac, named heart-purse, or capsule of the cardium. heart (pericardium), consists of two portions or layers, an outer or proper capsular, and an inner or lining division. The outer or proper capsular part of the pericardium pos¬ sesses the characters of a fibrous membrane, of some den¬ sity and considerable strength. When washed, its colour is gray or grayish-white, and it appears to consist of minute fibrous threads, arranged without definite order. These fibres are most distinct at its lower margin, where it is connected to the circumference of the tendinous part of the diaphragm. In the young subject it is generally thin and translucent; in adult age or advanced life it is thicker and more opaque. This part of the pericardium is a mere investing membrane, which bounds the region containing the heart, but which extends no further. It embraces the origins of the large vessels above, adheres to the margins of the tendinous centre below, and is on each side connected with the pleura. The inner surface of the pericardium has the appearance of a transparent or serous membrane, through which the fibres of the outer or capsular part may be seen, and which has the usual glistening aspect of such membranes. It is difficult, however, to insulate it from the outer layer, un¬ less by boiling, when it may be peeled off in minute shreds. Like the transparent membranes, this inner layer has neither beginning nor end, neither origin nor termination. After lining the inner surface of the proper capsule, it may be traced from the angle at which this capsule ad¬ heres to the large arteries and veins, over the auricles, and finally, over the outer surface of the ventricles to the apex of the heart. In this course it preserves the characters of a thin transparent membrane, with a free surface, smooth, glis¬ tening, and moistened by a watery fluid; and an attached one, adhering on the one hand to the inner surface of the capsule, and on the other to the outer surface of the heart by means of fine filamentous tissue. Injection shows that the pericardium consists chiefly of Spei i minute arteries and veins. The former are derived from AnatIJy. the thymic, phrenic, bronchial, oesophageal, and coronaries of the heart. The substance of the capsular part is pro¬ bably a modification of the white fibrous system. Nerves have not been traced to any part of this membrane; nor is it ascertained that it contains lymphatics. Of a general conical shape, the heart (cor) is situate The h k obliquely beneath and behind the sternum, with the base (basis) above and towards the right, and the tip (apex) pointing downwards, forwards, and towards the left. The axis of the cardiac cone lies at once obliquely from right to left and from behind forwards. (Plate XXXI.) The surface may be distinguished into two parts,—the ante¬ rior convex, appearing in the space between the right margin of the sternum and the sinuosity of the left lung; the posterior plane, resting chiefly on the oblique surface of the diaphragmatic tendinous centre. These two surfaces are united by a sharp anterior-inferior margin (inargo acu¬ ta), and an obtuse posterior-superior one (margo obtusa). It generally corresponds in size with the fist of the indivi¬ dual ; its average weight in the adult is about ten ounces; and its length from the middle of the base to the tip is about five inches. The base of the heart is circular, flattened behind, and presents an oblique groove, which indicates the limits be¬ tween the auricles and the ventricles. Each auricle is of a tetrahedral shape, and is distinguish¬ ed into the basilar or membranous part (sinus venosus), and the tip or proper auricle (auricula), a pyramidal angular process, the structure of which is muscular. The right auricle is the largest, the left smaller. The ventricles constitute the great part of the cardiac cone. Their anterior and posterior surfaces present each a longitudinal depression (sulcus longitudinalis superior et inferior), proceeding from the base to the tip, containing the anterior and posterior coronary vessels, and indicating the situation of the fleshy partition (septum ventriculorum) common to both ventricles. The interior of the right auricle behind presents above the opening of the superior cava (ostium venosum superius), below that of the inferior cava (ostium venosum inferius), larger, directed obliquely inward, with an intermediate eminence (tuberculum Loweri), denominated after Lower, and the Eustachian valve below (p. 721). Below and an¬ teriorly is the opening into the ventricle, bounded by a round margin (ostium inferius) ; above is the tip presenting muscular bands (musculi pectinati); and within is the par¬ tition common to both auricles (septum auricularum), with an oval depression (fossa ovalis), the residue of the fora¬ men ovale, occasionally bounded before by a crescentic slip of membrane. The right ventricle (ventriculus dexter velpulmonalis) is trilateral pyramidal in shape, with its base above corre¬ sponding to the inferior auricular aperture, its apex to that of the heart, the anterior-external wall corresponding with the anterior convex surface of the heart, and the pos¬ terior-internal with the common partition (septum cordis). It has two apertures—a right superior, communicating with the auricle ; and a left superior, communicating with the pulmonary artery. To the margin of the superior right aperture (ostium auriculo-ventriculare dextrum), which is round and thick, are attached several membranous triangular folds with two, or occasionally three apices, to which are fixed tendinous chords (chordce tendinece), with their opposite extremities terminating in muscular cylinders (muscuh papillares, m. teretes), connected with the fleshy walls ot the ventricle. This membranous fold, though often com¬ posed of two triangular slips only, is denominated the ANATOMY. 819 Sp:al three-pointed or tricuspid valve (valvula triglochin, v. tri- Anaimy. cuspidalis). Its apices hang into the ventricular cavity, and are prevented by the tendinous chords and their mus¬ cular bands from being forced back into the auricle. The left superior aperture (ostium arteries pulmonalis'), corresponding to the beginning of the pulmonary artery which is attached to it, is placed behind the inner slip of the tricuspid valve, by which also it is covered. The in¬ ner margin of the pulmonary artery presents three cres¬ centic or semilunar slips, named the sigmoid valves (val¬ vules sigmoideee), with their convex surface towards the ventricle, and the concave one towards the artery, and mi¬ nute bodies at the middle (noduli Morgagnii), correspond¬ ing to the axis of the artery. The interior of the left or posterior auricle presents on the right the two openings of the right pulmonary veins, on the left those of the left pulmonary veins, occasionally uniting in a single aperture, to the right and anteriorly the left surface of the septum, bounded before by a small semilunar slip, and below the aperture into the left or aor¬ tic ventricle. The left ventricle has the shape of an obtuse cone, with its base above and behind, and its rounded apex behind and to the left. It is rather larger than the right. The basis has two apertures, a large posterior one, com¬ municating with the auricle (ostium auriculo-ventricidare sinistrum); and a smaller anterior, opening into the aorta (ostium aorticum). To the ventricular margin of the for¬ mer is attached an irregular membranous slip, not dissi¬ milar to that of the right auriculo-ventricular opening, but always terminating in two apices, to which tendinous chords, connected with tapering muscular bands, are also attached. This has been denominated the bicuspid or mi¬ tral valve (valvula mitralis). Like the tricuspid, its apices hang into the ventricle, and are prevented from being re- truded into the auricle by the tendinous chords and papil¬ lary muscles. The aortic aperture, anterior and smaller, corresponds with the commencement of the aorta. Like the pulmo¬ nary aperture of the right auricle, it presents three semi¬ lunar valves, with the convex surface to the ventricle and the concave to the artery, and with central granules (cor- pxiscula Arantii). These valves are occasionally distin¬ guished into anterior, posterior, and inferior or lateral, according to their relation to the plane of the body. In their aortic side are generally small hollows, chiefly occa¬ sioned by distension of the aorta, named aortic sinuses. The heart consists chiefly of muscular fibres, closely united by filamentous tissue, covered externally by the reflected or cardiac portion of the pericardium, and inter¬ nally by a proper membrane. Each auricle consists of two parts,—a membranous- muscular, arranged in the stratified mode (fascia:), distin¬ guished as the sinus; and a fasciculo-muscular, distin¬ guished as the tip of the auricle, arranged in short parallel bundles (funes). The muscular Walls of the left ventricle are more than double the thickness of the right; and while those of the latter collapse on division, those of the for¬ mer retain their original disposition. The fleshy pillars of the interior of the right are small and slender compared with those .of the left, which are thick and strong. The arrangement of the muscular fibres of the heart, which has been studied by Senac, Wolff, Duncan, and Gerdy, is peculiar. Though mutually interlacing, like all the muscles of the entrophic order, the external are ar¬ ranged in layers (strata), while the internal affect the fasci¬ culated form. At the base they are incurvated round the basilar border, and wind obliquely towards the apex; but as they approach the latter region, more especially in the septum, they observe the longitudinal direction. The as¬ sertion of Soemmering, that they are distinguished as be- Special ing connected without filamentous tissue, is inaccurate. Anatomy I he adipose tissue at the surface, and towards the basev'->,“v~v—■ and apex of the heart, appears to be useful in facilitating motion in an organ in incessant action, and forms a soft cushion for the cardiac arteries. The inner membrane of the heart is thin and transpa¬ rent. In the right auricle and ventricle, where it is conti¬ nuous on the one hand with the inner venous membrane, on the other with the inner membrane of the pulmonary artery, it is evidently different from that in the left cavi¬ ties. It is thinner, and more delicate and transparent. Covering every recess, it is doubled to form the different valvular productions. By Bichat it is believed to be iden¬ tical with the inner venous membrane ; but this is mere supposition. In the left cavities the inner membrane is thicker and more opaque than the right; and its valvular duplicatures, which are much thicker, approach to the fibro¬ cartilaginous character. This is particularly the case in the aortic sigmoid valves, which often in the healthy adult are firm and elastic,not unlike the palpebralfibro-cartilages. The supposition of Bichat, that it is identical with the inner arterial membrane, with which it is continuous, is, in regard to the ventricle, not improbable. The heart is supplied with blood from the aorta by means of the right anterior or inferior, and the left su¬ perior or posterior coronary or cardiac arteries (arteries cardiacce), both issuing from the aortic sinus immediate¬ ly above the anterior and lateral sigmoid valves. The right or anterior coronary artery, lodged in the superior furrow, after sending several large branches to the septum and left ventricle, inosculates at the apex with a large branch of the left or posterior coronary. The latter, which is the largest of the two, after winding round the base of the heart towards the right, is recurvated at the thin mar¬ gin to the posterior surface, where it runs in the posterior furrow, and is divided into two considerable branches, the larger of which is distributed to the apex; while the smaller, running transversely between the left auricle and ventricle, winds round to the obtuse border, and terminates at the apex, where all the three vessels inosculate freely. The blood is returned by corresponding veins to the coro¬ nary, which terminate by one aperture in the right auricle. Its nerves are derived from the pneumogastnc and sym¬ pathetic. The four chambers of the heart (atria, atriola) are dis¬ tinguished into pairs,—a right auricle and ventricle com¬ municating mutually and with the pulmonary artery, and a left auricle and ventricle communicating with the aorta. The auricles, separated by the common septum, do not communicate in the natural state; and though in many hearts an oblique opening exists at the anterior margin of the oval depression passing into the left, the crescentic membranous slip by which it is covered prevents the blood of the right auricle from communicating with that of the left. The ventricles are separated also by a thick, fleshy, common partition, through which there is no direct communication, though it was a favourite subject of in¬ quiry before the time of Harvey, to discover communicat¬ ing apertures. The capacity of these chambers varies. The right au- Capacity of ricle is always more capacious than the left. The two the cardiac ventricles are, as near as may be, of equal capacity; and chambers, the discordant results obtained on this point by numerous inquirers show merely that any variation is accidental or dependent on the state of the organ during the close of life. The blood found in the right ventricle after death varies from 1^ ounce to 3 ounces. The capacity of the left, which is generally empty, is estimated by Meckel to vary from 8 to 20 drachms. 820 ANATOMY. Special The blood contained in the right chambers is modena- Anatomy. coloured or venous; that of the left chambers is scarlet- red or arterial. The former is derived from the venee Course of caV(B> which open into the right auricle; the latter from through t^ie pulmonary veins, which open into the left. The di- the cardiac section in which the blood flows on both sides is from the chambers, venous apertures into the auricles, thence to the ventricles, and thence to the respective arteries. The venous blood, on reaching the auricle, distends it, and impels its muscles to contraction ; and the cavity thus diminished expels the blood in the only direction in which it can proceed,—by the aurico-ventricular aperture into the ventricle. This chamber being distended, its muscular walls all round, especially at the base, contract and diminish its cavity, when the blood, extruded, quits the ventricle in the only direction in which it can, viz. by the aperture of the pul¬ monary artery. The blood from the pulmonary veins fol¬ lows the same course in the chambers of the left side. The blood of the ventricles is prevented from returning into the auricles partly by the tricuspid and mitral valves, but chiefly by the annular contraction of the auriculo-ven- tricular apertures, which are drawn from the margins to¬ wards the septum; while the latter is shortened, and the apex is made to approach the base.

Connected with each ventricle is a large tube, in which the blood flows from the trunk to the branches. The pulmonary artery, the first of these, divaricates into a right and left branch, subdivided and distributed respec¬ tively to the right and left lung. The aorta, which is the second, is the large artery which distributes the blood after aeration in the lungs to the system at large. The aorta, rising from the left ventricle, after giving off the cardiac arteries, makes an antero-posterior incurva¬ tion with the convexity upwards, denominated the arch or curvature (arcus aortce). (Plate XXXI. A, A.) From the upper side of this arch arise three large vessels, the innominata or subclavio-carotid, the common trunk of the right subclavian and carotid arteries (i), the left carotid (i), and the left subclavian. The aortic trunk, after this curvature, proceeds downward on the left margin of the dorsal vertebrae, giving oesophageal, bronchial, and superior intercostal arteries, thymic, pericardial, and in¬ ferior intercostal arteries successively. From the level of this arch to the parabolic opening of the diaphragm at the tenth dorsal vertebra, it is distinguished by the name of thoracic aorta ; and below this, to the fourth lumbar verte¬ bra, it is the abdominal aorta. At its transit through the parabolic aperture it sends off the diaphragmatic arteries. The vessels issuing from the abdominal aorta may be dis¬ tinguished into two orders, those which issue from its sides in pairs, and those which issue from its anterior surface sing¬ ly only. The former consists of the capsular, distributed to the renal capsules; the renal or emulgent, to the kidneys ; the spermatic, to the testes ;' and the lumbar, to the lumbar muscles, and that region generally. The latter are three in number only, the cceliac, superior mesenteric, and inferior mesenteric. Opposite the fifth lumbar vertebra, or the fibro- cartilage uniting the fourth and fifth, the aorta terminates by divaricating into two large lateral trunks, the common or primary iliacs (iliacce communes'); while from its middle be¬ hind proceeds a small azygos artery, distinguished as the sacro-median, along the median line of the sacrum. In this course the aorta is placed in the posterior angle of the thoracic and abdominal serous membranes, and, inclosed by the anterior vertebral filamentous tissue, sends from its posterior surface numerous arteries to the vertebral column and spinal chord. % g f External thoracic.

Thus it is often difficult to determine whether the temporal artery or the internal maxillary is the con¬ tinuation of the external carotid, which of the palmo-digital arteries is the continuation of the radial, whether the an¬ terior or the posterior tibial artery is the continuation of the popliteal, and whether the dorsal of the foot is the termination of the former, \thly. In the terminal vessels, where inosculation is frequent, it is impossible to deter¬ mine whether an artery arises from one trunk or another. Thus in the arterial arches of the hand and foot, in which the digital vessels issue from the convexity of the arch, it is impossible to say whether these arteries arise from the radial or the ulnar in the one case, or the anterior or the posterior tibial in the other. The arteries are accompanied by veins, which in gene¬ ral correspond, for the purpose of conveying the residual blood, after distribution, to the right chambers of the heart, to be transmitted by the pulmonary artery to the lungs for renovation. The veins of the head, chest, and superior extremities, open into the superior cava ; those of the lower part of the trunk, the pelvis and pelvic ex¬ tremities, terminate in the inferior cava ; the veins of the stomach, intestinal canal, spleen, and pancreas, terminate in the portal vein; and the regredient hepatic veins are united in one vessel, which terminates in the upper end of the inferior cava. SECT. II. THE ORGANS OP AERATING CIRCULATION, OR RESPIRATION. The lungs are two soft, spongy, vascular bodies, con¬ tained in the cavity of the chest, one on each side, and imitating in shape the internal figure of that region. Each lung, resembling somewhat a cone, with one side truncated, and the base obliquely cut, is distinguished into a convex external surface, corresponding to the concave internal one of the thorax ; a flat inner or mesial surface, corresponding to the mediastinum ; a rounded obtuse apex, corresponding to that of the demithorax; and a concave base directed obliquely from the mesial plane to the hypochondres, cor¬ responding to the convex surface of the diaphragm. Each lung is distinguished into lobes (lobi) separated by fissures (incisurce). The right, which is the largest, consists in general of three lobes, the superior, middle, and lower; the left of two only, an upper and lower. The mesial margin of the left is distinguished from that of the right by a sinuous notch, indicating the situation of the heart (fovea cardiacd). The intimate structure of these bodies, which has been the subject of much research, depends on the nature of the tubes which are distributed to them, and of which chiefly they consist. These are the bronchial or breath- tubes (bronchi), the continuations of the windpipe, and the branches of the pulmonary artery and veins. ’ O M Y. 821 The windpipe (trachea) is a cylindrical tube, about four Special or five inches long, extending from the cricoid cartilasre, to Anatomy, which it is attached by a fibro-mucous membrane behind the sternum, to the level of the third dorsal vertebra, or the fibro-cartilage between it and the second. (Plate XXXI. t.) It consists of from 17 to 18 or 20 cartilaginous rings (annuli), truncated behind, united by a fibrous membrane without, continuous, but particularly firm in the interannu- lar spaces, and along the whole posterior part of the canal. These fibres are white, firm, longitudinal, and closely set. Within is the mucous membrane, continued from the la¬ rynx to the bronchi, resting on filamentous tissue, in which are embedded the mucous follicles. By many, muscular fibres have been represented to exist between the rings ; according to Soemmering transversely and longitudinally; and Reisseissen has recently maintained their reality at the posterior part of the tube. Their fibrous disposition is undeniable, but their muscular character maybe doubted. The windpipe, covered before by the thyroid gland, and corresponding to the sigmoid pit of the sternum, is at¬ tached to the oesophagus behind by filamentous tissue. Opposite the third dorsal vertebra the trachea is bifur¬ cated into two tubes named air-tubes (bronchi), which are directed obliquely to each lung with a mutual intermediate angle of about 35°. The right is about one fourth larger and one fifth longer than the left. Both are cylindrical, but divaricate at their lower end, where they sink into the substance of the lungs, into several smaller tubes (Srowc/«'a), which again ramify and subdivide into tubes still smaller, and successively. The interbronchial angle is occupied by lymphatic glands, which are also arranged round the tubes. The bronchi consist of cartilaginous rings, complete above, but parted into three annular segments between the middle and lower ends, united by whitish fibrous tissue, longitudinal externally, transverse within, and lined by mucous folliculated membrane. As they advance into the substance of the lungs, and are still more minutely divid¬ ed, the cartilages diminish in size and firmness, and their place is supplied by fibrous tissue of transverse circular fibres, which at length also disappear, and mucous mem¬ brane alone is left. These transverse annular fibres have been supposed by Haller, Soemmering, and recently Reisseissen, to be mus¬ cular. It is not improbable that they are so; but no posi¬ tive proof of this fact has yet been adduced, and they ap¬ pear rather to belong to the elastic fibrous system. The larger bronchial tubes are accompanied each by an artery derived from the aorta or the subclavian, and fol¬ lowing their ramifications into the pulmonic substance. The blood conveyed by these vessels is returned either to the vena azygos or the superior cava. The pulmonic or final divisions of the bronchial tubes terminate in blind sacs covered by mucous membrane, and communicate with each other, forming an appearance of intersecting compartments, which have been distinguish¬ ed by the name of air-cells (cellulce aerece), or pulmonic vesicles (vesiculce pulmonis). Lhey are represented as polygonal and irregular, and about one eighth or one tenth part of a line in diameter. (Haller and Soemmering.) On the whole, these air-cells appear to be merely the termi¬ nations of the bronchial tubes mutually communicating, lined by a very delicate mucous membrane. The pulmonary artery, ramified and subdivided to a great degree of minuteness, communicates most freely with a number of vessels, which may be traced into trunks terminating in the pulmonary veins. This capil¬ lary system, enveloped in filamentous tissue, is distributed beneath the mucous membrane of the terminal bronchial tubes or communicating cells. The exterior surface of this filamentous tissue is covered by the pleura. From ANATOMY. 822 Special these facts it results that the lung consists of cartilaginous Anatomy. an(j fibrous tubes mutually intersecting, and the capillary communications of the pulmonary artery and veins, inve- loped in filamentous tissue, lined on one side by mucous membrane, covered on the other by transparent serous membranes. The air-cells, lined by mucous membrane, have no communication with those of the filamentous tissue, as some have absurdly imagined. Except this fila¬ mentous tissue, the lung has no proper substance or paren¬ chyma ; and its structure is entirely filamento-vascular. In the capillary vessels of the pulmonary artery and veins, the venous or modena blood, exposed to the in¬ fluence of the inspired air through the thin bronchial membrane, parts with its dark, and gradually acquires a bright red tint. This may be styled the aerating or ar- terializing capillary system. The lung, however, receives other vessels, the bron- chials, by which its mucous aerating membrane and sub¬ mucous tissue are nourished. Entering with the bron¬ chial tubes between the folds of their pleura, these ves¬ sels are subdivided as they proceed, and at length form a minute network on the attached surface of the bronchial mucous membrane. The lung derives its nerves from the eighth pair chiefly, and a few filaments from the great sympathetic. The lung is well supplied with lymphatics, both superficial and deep. SECT. III.—THE ORGANS OF SECRETORY CIRCULATION, OR SECRETION. Of the organs of secretory circulation, several, as the lacrymal gland, the salivary glands, the liver, and pan¬ creas, have been already considered ; and others, for ex¬ ample the testes, will fall under subsequent heads. This, however, is the proper place to notice the organs of the urinary secretion, which consist of two glands, the kidneys, and two excretory ducts, the ureters, terminating in a common receptacle, the bladder. The kid- The kidneys (renes) are two glandular bodies situate neys. jn ^fie posterior or lumbar part of the abdominal region, one on each side of the lumbar vertebrae, behind the pe¬ ritoneum, and before the psoas muscle and part of the diaphragm, with the quadratus lumborum behind and la¬ terally, and enveloped in a thick layer of adipose tissue. The right kidney is below the liver, above the caecum, behind part of the duodenum, colon, and the right extre¬ mity of the pancreas. The left is bounded above by the spleen, by the transverse arch of the colon before, and it has the sigmoid flexure below. The right kidney is about two inches from the outer margin of the vena cava, and the left at about the same distance from the outer margin of the aorta. The situation of the right kidney is generally lower than that of the left, so that part of its lower extremity is in the iliac/ossa, while the lower extremity of the left is quite above the margin of the ilium. Resembling in general shape the large French bean, named from it, each kidney may be described as an ob¬ long body, convex externally and at both ends, and with a sinuosity at its inner margin, named the renal fissure (fovea renis'), in which the vessels and excretory duct are contained. Each kidney is between four and five inches long, and two broad; and the weight of each varies from three to four ounces. The anterior surface, correspond¬ ing but not attached to the outer surface of the peri¬ toneum, it convex, but becomes hollow at the inner mar¬ gin, where it terminates in the renal fissure. The pos¬ terior surface, which is less convex, is separated from the internal aponeurosis of the transverse abdominal muscle, the diaphragm, and the psoas magnus, by a thick layer Speck of adipose tissue. Anaton The kidney consists of glandular structure, invested by'^’~v''1 a firm membrane, somewhat fibrous in appearance. In the glandular structure the anatomist recognises theStructu I most distinct example of this form of tissue. It consists of two parts, a granular external, and a tubular internal. The former, which occupies the exterior of the kidney, is a homogeneous substance, of a yellow fawn colour, and con¬ sists of minute spherical or spheroidal granules (granuld), aggregated together by filamentous tissue, and forming at their exterior calycoid or cup-like cavities, in which the round fundi of the tubular conoids are lodged. In these the capillary vessels of the kidney are ramified with great minuteness. The tubular part consists of very minute capillary tubes (tubuli uriniferi, tubidi Belliniani), varying in length, united by filamentous tissue, and arranged in parallel juxtaposition, so as to form conoids with globu¬ lar bases, which are lodged in the cup-like cavities of the granular portion, and rounded apices directed to the renal fissure. The number of these tubular cones varies from 10 or 12 to 18 or 20. Their apices form an equal num¬ ber of nipple-like processes (papillae), covered by a thin membrane almost transparent, in which are numerous minute holes, apertures of the tubes of which the cones are composed. These apertures, however, are much less numerous than the tubes, several of which are united in one common orifice. The renal papillae thus constituted project into a series of conical cavities, formed within of the papillary membrane, without of fibrous strata and fila¬ mentous tissue. These cavities, which from their shape are denominated funnels (infundibula, calyces), uniting into three or four larger ones, terminate in a considerable membranous sac named the basin (pelvis) of the kidney. These two parts of the kidney are distinguished not only in structure but in colour and consistence. While the granular part is fawn-coloured, and somewhat soft and flabby, the tubular is pink-red, fleshy and firm; and the boundary line is distinct. The tubular cones are separated from each other by partitions, which appear to be fila¬ mentous tissue. There is no doubt that the granular is the secreting part of the gland; and the tubes are merely conduits of the urine, which indeed may be expressed from their apertures. It is important, however, to determine the mode in which the two portions communicate. The as¬ sertion of Ferrein and Eysenhardt, that the tubes are blind canals, is inaccurate in this respect, that the terminal tubes evidently communicate with others in the interior of the cones, which again are immediately connected with the granular part. It further appears, that in the granu¬ lar part there are very minute white tortuous canals, which appear to communicate with the straight tubes of the cones. All beyond this is entirely conjectural. The kidney, therefore, cannot be said to possess paren¬ chyma or proper substance. The idle distinctions into cortical and medullary ought to be rejected as remnants of an exploded theory. The kidneys are supplied with blood from the aorta by Blood-v, the renal arteries. Issuing at right angles from the late-seh- ral regions of the abdominal aorta, below the superior me¬ senteries, these vessels pass directly into the fissure at its superior and anterior part, the left behind, the right occa¬ sionally before the renal vein, but crossing its direction. The calibre of these vessels is considerable, about three lines at least; and they have been estimated to convey the sixth part of the blood of the abdominal aorta. The left artery is about one inch long, the right is the whole breadth of the vertebral column longer. In the renal fissure each artery divaricates into three or four consider- ANATOMY. pecial atom v. basin I t'/w. un. blad. ^iture. able branches, which enter the kidney a little above the (attachment of the basin (pelvis'). These vessels are a^ain subdivided into an anterior series before, and a posterior cluster behind the ifij^unclibulct^ which they accompany to the papilla!. Dividing more minutely, they form anasto¬ motic arches, fiom the convexity of which proceed minute vessels, radiating into the granular substance of the gland. These vessels are distributed principally to the granular matter at its calycoid surfaces, in which the tubular cones are lodged. The veins are arranged exactly in the same manner, and connected with the renal trunk, much as the arterial branches are connected with it. The kidney is supplied with nerves, accompanying the arteries, derived from a plexus inclosing the renal trunk, and which is originally formed from filaments of the solar of the great sympathetic. The pelvis consists externally of a prolongation of the renal investment, a proper middle membrane, white, opaque, and fibrous, and an inner lining, which, though thin and semitransparent, presents the character of mu¬ cous membrane. I he upper extremity of each kidney is covered by the renal capsule, a substance of no peculiar structure, and the nature of which is unknown. The basin forms the common termination of the renal funnels, and the commencement of the ureter. This is a membranous tube, of the diameter of a moderate-sized quill, passing between the renal basin, behind the perito¬ neum, to the posterior and inferior part of the bladder, in which the lower extremity opens. Each ureter is inclin¬ ed to the mesial plane below. The right ureter is on the outside, and nearly parallel with the inferior cavity. Both cross the psoas at an acute angle, and below the common iliac arteries and veins. In the pelvis they cross the vas deferens in the male, and on reaching the bladder pass ob¬ liquely, from eight lines to an inch, through its coats, and open in the posterior margin of the lower fundus of that organ. These tubes consist of fibrous membrane, lined by mu¬ cous and covered by filamentous tissue. It contains no muscular fibres, notwithstanding the assertions of some. The ureters are supplied with blood derived from the renals, occasionally from the lumbars and spermatics, but more especially from the aorta by two ureteric arteries. The urinary bladder is a muscular membranous bag, spherical above and cubo-spherical below, placed on the lower region of the pelvis, behind the pubal symphysis, and before tbe rectum in the male, and the uterus in the female. From the peculiarity of its figure and relations, it is distinguished into a superior/hncfos, spheroidal, direct¬ ed to the abdominal cavity; an vafeviovfundus, cubo-sphe- roidal, between the ureters and urethral opening; a neck (cervix), pyriform at the latter point; an anterior surface, corresponding to the posterior of the pubal symphysis; a posterior, corresponding to the rectum in the male and the uterus in the female; and lateral regions, corresponding to the ilio-ischial inner surface, and those of the obturator interims and levator ani. In females generally the transverse extent of the blad¬ der is greater than in the male, and in females after child¬ bearing than in the virgin. In infancy its superior fundus is pointed and conical rather than globular,—a peculiarity derived from its foetal shape, which is pointed, with the urachus, a ligamentous chord proceeding to the navel, at¬ tached. The bladder consists of a muscular coat, covered above, behind, and laterally by peritoneum, and lined by mucous membrane. The peritoneal covering is continued from the anterior 823 surface of the rectum, and the lateral regions of the pelvis Special over the posterior and lateral and part of the superior sur- Anatomy, faces of the bladder, all of which are free ; while the infe- nor fundus, the neck, and the anterior, are covered by fila¬ mentous tissue, connecting the organ to the neighbouring parts. This filamentous tissue is abundant, especially below. 1 he muscular coat, always distinct, varies in thickness in different individuals. In females, so far as we have ob¬ served, it is rather thicker than in males. The fibres run in all directions, but are strong at the superior surface, where some anatomists have arbitrarily distinguished them by the name of detrusor urince. There are no fleshy pillars, mentioned by some, in the healthy state. The neck is surrounded by a thick range of circular fibres, which has been denominated the sphincter of the bladder. I he mucous membrane, without villi or epidermis, is ex¬ tended over the whole inner surface of the organ, and is continuous behind with that of the ureters, and before with that of the urethra. The space inclosed between these three orifices is named the vesical triangle (trigonus vesicce); and a minute duplicature of the mucous membrane at the urethral orifice is denominated the vesicce uvula. The bladder is supplied with blood chiefly from the posterior iliac or hypogastric trunk, by means of the com¬ mon pudic, the obturator, the ischiatic, and the hemor¬ rhoidal. Of these, one vesical artery proceeds from the hemorrhoidal; another often comes off' directly from the hypogastric as an inferior vesical; and in some instances they issue from the umbilical. The vesical nerves are partly from the sympathetic, partly from the sacral. The capacity of the bladder varies in different indivi¬ duals. In the female it is generally more capacious than in the male. In the healthy state it may contain a pound of urine, without extreme distension ; and it is often ca¬ pable of containing two, three, or four pounds. Its situa¬ tion varies at different periods of life, and in different de¬ grees of distension. In the foetus and infant, when the pelvis is small, the bladder is contained in the abdomen. In the adult in the ordinary state it is within the limits of the pelvis ; but when much distended, its superior fundus, rising above the pubis, is in the abdomen. During preg¬ nancy, also, it is thrust forwards and upwards by the gravid womb. Urine, the fluid secreted by the kidneys, is particularly distinguished by containing, with various saline substances, urea, an animal principle containing 46 per cent, of azote. As the saline ingredients also abound in principles con¬ taining this element, it may be inferred that the chief pur¬ pose of the kidneys is to remove from the system a con¬ siderable proportion of nitrogen, which would either be injurious by its presence, or disturb the due proportion of the other elements. The urethra, which terminates the urinary apparatus, is nevertheless common to it with the reproductive organs. The male urethra especially is more connected with the reproductive than the secretory organs. In the female, in whom alone this canal is proper to the latter, it is a short muco-membranous tube, terminating in a papillated ori¬ fice in the superior anterior wall of the vagina. PART III. ANATOMY OF THE ORGANS PERTAINING TO THE REPRO¬ DUCTIVE FUNCTIONS. These organs, by the possession of which the indivi¬ duals of the human race are distinguished into two sexes, male and female, consist in the former of impregnating, and in the latter of the impregnable organs. The former may be again distinguished into preparing and transmitting 824 ANATOMY. Special organs; and the latter into receiving and ootrophic organs, Anatomy. 0r those which nourish the product of generation. CHAP. I. THE MALE OR IMPREGNATING ORGANS. The scro¬ tum. The vagi¬ nal coat. The albu¬ gineous coat. The tes¬ ticle. The semi niferous tubes. The male organs consist of two glandular organs, named testicles with excretory ducts, for secreting the impreg¬ nating fluid, and an organ for transmitting it to those of the female. The testicles (testes) are two ovoidal bodies contained on each side of the mesial plane in a cutaneo-cellular sac named the scrotum, attached to the anterior inferior part of the pubal symphysis. The scrotum consists of skin with very thin corion, rest¬ ing on loose filamentous tissue, which forms on the mesial plane a thick wall, separating the right half of the scrotal bag from the left. On the median line is a superficial groove, named suture (raphe), at which the corion and filamentous tissue, elsewhere loose, are united into a solid and firm substance. Most of the old anatomists mention a muscular layer known by the name of dartos, and to which they ascribe the contraction of the scrotum on ex¬ posure to cold; but the existence of this muscular layer is not supported by inspection. The scrotal skin is well Supplied with arteries, and especially veins connected with those of the epigastric, external iliac, femoral, obtu¬ rator, and external pudic, the branches of which anasto¬ mose freely. The nerves are from the lumbar, obturator, and crural. The scrotal filamentous tissue incloses on each side a thin membranous sac of a pyriform shape, with the base below, and tapering to a neck above. Adherent on the outside to the filamentous substance, this membranous sac is free and smooth within, except at the neck, where it embraces a part distinguished by the name of spermatic chord. This, which is the sheath-like or vaginal coat (tunica vaginalis), is distinguished into two parts, an in¬ ferior pyriform, forming a cavity for the testicle, and a su¬ perior cylindrical, covering the spermatic chord, and ad¬ hering to it. This membrane is said to be fibrous exter¬ nally ; but it appears to be merely condensed filamentous tissue. Within it is evidently a transparent serous mem¬ brane, both in qualities and distribution. It is continued from the adherent part of the chord downward, and over the testicle. Within the cavity of the former are contained the tes¬ ticles, both suspended by the spermatic chord, with the epididymis behind. Their substance is inclosed in a firm, opaque, white, fibrous investment, covered by a thin trans¬ parent membrane, reflected from the vaginal coat. The former is the tunica albuginea, or proper tissue of the gland; the latter is the vaginal coat of the testicle (tunica vaginalis testis). The testicle consists of minute irregular-shaped gra¬ nules, of a white or gray-white colour, soft, closely com¬ pacted, and with numerous capillaries distributed through them. More minutely examined, these are found to be capillary tubes of extraordinary length, folded on them¬ selves, and contorted so as to occupy a small space, and when unfolded extending, according to some anatomists, . 16 feet, according to others to 25 or even 100 ells. These long tortuous tubes, which are named the seminiferous (ductus seminiferi), are estimated at about 300 in num¬ ber. They communicate by one extremity with the blood¬ vessels and lymphatics of the testicle, and by the other, after several unite into one common duct, terminate in about 20 larger tubes, denominated egredient ducts (vasa efferentia), which, united in a cluster by means of fila¬ mentous tissue, and invested by part of the tunica albugi¬ nea, form at the upper part of the gland a whitish cylin¬ drical body, about six lines long and two broad, distin- Specif; guished by the name of the process of Highmore (corpus Anatoir Highmori). These efferent vessels unite and form a singlev^v> tube of great length, which, folded on itself by innumer-The Prc able turns, connected by filamentous tissue, and invested VJ by tunica albuginea, constitutes the epididymis, attached The epil by its head to the testicle, and by an incurvated extremity didymis, named tail, continuous with the common excretory duct (vas deferens). The latter is a long fibro-cartilaginous tube, ascending The vas upwards from the tail of the epididymis, and making deferen: part of the spermatic chord, with which it enters the®^1™^ abdomen at the inguinal aperture. At the inner margin duct 01 of this it separates from the chord, and descends into the pelvis, first by the side, then at the posterior and mlerior fundus of the bladder; and, approaching that of the opposite side with the vesicula seminalis on the outer margin, each vas deferens is in contact with the other at the base of the prostate gland. Here each receiving a tube from the corresponding vesicida, forms a common duct (ductus ejaculans), which traverses the prostate, and terminates in the urethra about one inch and a half from its vesical end, on each side of the eminence named veru- montanum. The spermatic chord, by which the testicle is suspended, SpermatS consists of the spermatic artery or its divisions, derived incho^J• general from the aorta, two or three spermatic veins, seve¬ ral lymphatics, and the vas deferens, inclosed in filamentous tissue, and covered by a slip of muscular fibres denomi¬ nated the suspensory muscle (cremaster, tunica erythroides), detached partly from the internal oblique and transverse of the belly, fixed partly at the inner surface of the liga¬ ment of Poupart and the tuberosity of the pubis. The spermatic artery divaricates into several branches, which are distributed, after a few sent to the epididy¬ mis, among the seminiferous ducts. They communicate with numerous tortuous veins, which are collected into a cluster known by the name of \X\epampiniform body, situ¬ ate immediately below the tunica albuginea. Below the mferior fundus of the bladder, on the outside Seminal of that organ, are placed two bodies, oblong, flattened,vesic es' pyriform, with the base behind, composed at first sight of a series of cells separated by septa. Each of these bo¬ dies, which have been named the seminal vesicles (vesicu- Ice seminales), consists of a long tortuous membranous tube, convoluted on itself, and with the folds aggregated by bridles of filamentous tissue, which convert it into communicating sacs. The cavity of this canal, which communicates with the urethra by a tube, common to the vesicles and the vasa deferentia, has been supposed to serve as a reservoir for the seminal fluid after secretion by the testicles ; but this supposition is by no means ve¬ rified, and is open to several objections. The transmitting organs consist of the penis with the urethra and prostate gland. The penis, the shape of which is well known, consists, ofTlm ca\ two parts, the cavernous body (corpus cavernosum), and thenoUs spongy body (corpus spongiosum) containing the urethra. The cavernous body, single before, bifurcated behind, may be described as two cylindrical bodies, inclosed in a fibrous investment, which, uniting them on the mesial plane, forms a partition (septum medium), perforated nevertheless with orifices for vessels. The divaricating posterior extremities (crura) are firmly attached to the ischio-pubal rand on each side. The intermediate trian¬ gular interval is occupied by the perineal filamentous tissue, fat, the perineal muscles, and the spongy body in the middle. Above and before, both are connected to the pubal symphysis by a triangular, flat, fibrous substance, named the triangular or suspensory ligament. ANATOMY. cial TTie spongy body is a cylindrical cellulo-vascular tube, Afomy. inclosing the urethra, and occupying the middle depres- sjon> aiong the lower surface of the cavernous body, from Tl|p°ngyits anterior extremity, where it constitutes the glam, to the angular bifurcation of the cavernous body, where it is expanded into a substance denominated the bulb of the urethra. The spongy body is invested on the side and below by integuments only. Both these parts, but especially the cavernous body, consist of numerous minute arteries, communicating di¬ rectly with elongated and dilatable veins, and constitute the best example of erectile arrangement in the body. The injection of these vessels constitutes the erection of the penis, and induces the contraction of the urethra necessary to expel the seminal fluid. The two extremities of the spongy body, the glam before and the bulb behind, form the limits of the erectile tissue round the urethra. The anterior extremity is covered by loose skin, which forms the foreskin (prceputium), and, in the shape of a thin semi- mucous corion, provided with epidermis, is continued over the glans, from which it passes insensibly into the mucous membrane of the urethra. With the penis several muscular organs are connected. The ischio-cavernosm and tramversus perincei on each side connect the cavernous body to the ischium; and the bulbo-cavernosus connects it to the bulb of the urethra. Mr Houston of Dublin has lately discovered a packet of muscular fibres situate between the pubal arch and the penis on each side, which, by compressing the dorsal vein, may, he imagines, contribute to erect the organ. The cavernous and spongy bodies are supplied with blood from the terminal end of the internal pudic artery, by means of two vessels, the cavernous and the dorsal. The bulb receives branches from the transverse perineal artery. The prostate gland is a body cordiform or flat conoidal m bid. in shape, with the base behind and the apex before, cor¬ responding to the vesical end of the urethra, situate behind the pubal symphysis before, and below the neck of the bladder, in the angle between it and the rectum, and be¬ tween the levator ani of each side. It is distinguished into three lobes,—two lateral, united on the mesial plane,—and a small cellulo-vascular slip in the angle between them, towards the base. In structure it is composed chiefly of minute arteries and veins rami¬ fied in a firm, fleshy, filamentous tissue, amidst which are placed follicles with minute ducts, which terminate in larger tubes, varying in number from seven to twelve, the apertures of which are on the sides and the surface of the urethra. These follicles secrete a viscid liquor, the use of which is unknown. From the fact, however, that, when the prostate gland is diseased or injured, the sexual ap¬ petite is languid or extinguished, it may be inferred that the prostate is essential to the generative functions in the male. It is analogous to the uterus in the female. With the prostate may be mentioned the accessory glands of Cowper, two small bodies, oblong-round, placed on each side of the urethra, before the prostate. They appear to be mucous follicles on the large scale. The urethra is a membranous canal, extending from the neck of the bladder in the pelvis to the extremity of the glans, where it terminates on the surface by an aper¬ ture (orijicium urethra), consisting of two lateral seg¬ ments. Its length and width vary in the erect and unerected state of the penis. In the latter it is about seven or eight inches long, and its calibre is about three lines, but admitting of distension beyond this. Accord¬ ing to the parts with which it is connected, it is distin¬ guished into four different portions ; ls£, the prostatic, about one inch ; 2d, the membranous, from one to one inch and a half; ‘M, the bulbous, scarcely one inch; and, ith, VOL. II. 825 «;r’s !ri the spongy portion, occupying the anterior part of the Special canal, inclosed by the spongy body. Anatomy. .The surface of the urethra is a mucous membrane sup-'^^~v^^ plied with follicles, and moulded into blind sacs named lacuna, which appear to contain mucous ducts. Its capacity varies in different parts. Wide at the middle of the prostate, it is contracted in the membranous part, which is indeed the narrowest of the canal; it enlarges again in the bulb; and from this it preserves the same diameter to immediately behind the glans, where it forms a dilatation distinguished by the name of the navicular (fossa navicularis). The apertures in this canal have been already mentioned to be, besides that of the bladder, one ejaculatory on each side of the veru-montanum, from seven to ten excretory apertures from the prostatic ducts, and one aperture from each accessory gland. The mu¬ cous membrane of the membranous and spongy portions presents longitudinal folds, which appear to be connected with the occasional distensions of the tube for the expul¬ sion of the urine. The urethra, straight in direction on the mesial plane, is incurvated within the pelvis from behind forwards, so that its concave incurvation incloses the pubal arch, while its convexity is turned to the perinaeum. The pen¬ dulous state of the penis, when unerected, causes it to ac¬ quire another incurvation without the pelvis, with the con¬ vexity directed upward. These curvatures are consider¬ ably exaggerated in engravings. The first round the arch of the pubis is much less angular than it is delineated. CHAP. II.—THE FEMALE OR OOTROPHIC ORGANS. The female generative organs consist of the ovaries, the uterine or Fallopian tubes, the womb, and the vagina. These organs are contained in the pelvis. From the time of Steno, anatomists have given the name The ova- of ovaries or eggbeds (ovaria) to two ovoidal bodies, about ries. the size of a pigeon’s egg, placed one on each side of the womb in the pelvis, in a duplicature of peritoneum termed the broad ligament (ligamentum latum) of the uterus. Con¬ vex and free on their anterior and posterior surfaces, and tapering towards each extremity, their lower margin is straight or slightly concave, with a vascular sinuosity. The external extremity is contiguous to a round solid chord (ligamentum teres), forming the anterior margin of the broad ligament, and proceeding from the womb to the internal orifice of the inguinal canal and the pubal extre¬ mity of the ligament of Poupart, and by which the uterus is retained in the pelvis. Each ovary weighs about one drachm and a half. Covered externally by peritoneum, stretched over a Ovarian fibrous membrane of some firmness, the ovaries consist of vesicles or a pulpy brownish-gray substance, very vascular, in which germs* are embedded minute bodies of vesicular appearance and oval shape, varying in number from 15 to 20. These bo¬ dies, which, from the time of De Graaf at least, have been regarded as ova or embryal atoms or germs (ova Graaji- ana, ovarii vesicula), consist of a thin membrane contain¬ ing a viscid, reddish, or yellow fluid. The ovary is supplied with blood from arteries analo¬ gous to the spermatic of the male. Previous to puberty the ovaries are smooth in surface and entire. After this period, both in females who have had children, and even in virgins, they are marked on the surface by minute depressions, which have been denomi¬ nated cicatrices, and which are believed to be the conse¬ quence of minute breaches of the ovarian tunics, occasion¬ ed by the escape of the vesicles from the surface of the ovary. There is no proof that these cicatrices are the invariable result of sexual intercourse. Small before pu¬ berty, at that period they acquire considerable size, and 5 M 826 ANATOMY. Uterine tubes.

Small before puberty, at that period it is about 2\ inches long, broad at its widest part, and weighs from 7 drachms to ounce. It is distinguished into \he fundus, body {corpus), and neck {cervix); the first free, directed surface of which the ovum is attached by a vascular body denominated ihe placenta or after-birth. The vagina is a membranous vascular tube, situate onThevi the mesial plane, behind the pubal arch, and before theg™- rectum and urethra, and extending from the neck of the womb in the pelvic cavity to the external outlet {vulva), where it is continuous with the surface. Not exactly cylindrical, but flattened before and behind, its length is about four inches, its breadth one, but very distensible. It is generally distinguished into the upper vaginal recess {vagince fundus), inclosing the neck of the womb behind the os tincce, the lower vagina {vagina propria), and the upwards; the second also free, between the bladder and vaginal opening {vulva) rectum; and the third connected within and below to The vagina consists of mucous membrane surround- the vagina. At each side of the fundus is a corner or ed by filamentous tissue, a vascular network, and some angular part, which communicates with the uterine ex- muscular fibres. The mucous membrane, wiiich is red tremity of the Fallopian tube. The neck of the womb below, gray above, and not unfrequently marbled, soft may be distinguished into the external or peritoneal, and and spongy, is disposed in numerous large transverse the internal or mucous neck, which terminates in an ellip- and semicircular folds {rugce) on the anterior and poste- tical opening, with rounded, thick, firm margins, not unlike rior surfaces. In the recesses of these folds are numerous the mouth of the tench, and named therefore os tincce, pores, evidently the source of the mucous viscid secretion as well as os uteri. These lips become rough and irregu¬ lar in women after child-bearing, in consequence of the distension during parturition. The cavity of the womb is small compared with the volume of the organ, in consequence of the thickness of its containing walls. It is triangular in shape, with the base at the fundus, and the apex at the neck. The su¬ perior angles are small recesses, in which the uterine ex¬ tremity of the Fallopian tube of each side opens. The cavity is much contracted at the neck, forming a short which is so abundant on this membrane, during sexual excitation, at the period of parturition, and morbidly in gonorrhoea in the female. On the lateral regions it pre¬ sents pyramidal eminences (papillce). The mucous membrane is connected by filamentous tissue to another, which in the vicinity of the uterus is compact, firm, and elastic, and below, towards the ori¬ fice, is thinner, and contains a network of numerous com¬ municating vessels, in which the blood is occasionally ac¬ cumulated in the manner of erection.

Of a hemispherical or conical shape, the female breast consists of a glandular organ, named the mammary, sur¬ rounded by adipose tissue, and covered by integuments. It is distinguished into the breast (mamma'), the nipple (papilla, mammilla), and a coloured ring of skin (areola). The gland is of a flat, rounded figure, and consists of lobes of white pulpy substance, separated from each other by filamentous tissue, and which may be resolved into granules or acini about the size of millet seeds, which again are composed of minute oblong vesicles disposed in a radiating manner. From the granules or acini proceed minute tubes named the lactiferous (ductus lactiferi, tubuli galactophori), which uniting into larger tubes, varying in number from 20 to 30, terminate in the centre of the mammary gland, behind the areola in conical dilated sacs (sinus), varying from one or two to three lines in diame¬ ter. These galactophorous ducts, which are larger than in any other gland, are formed of mucous membrane, which extends into the sinuosities, and is at the nipple identified with the skin. Several of the lactiferous tubes are said to originate from the adipose tissue of the breast; but this seems merely to indicate that they communicate with the vessels of this substance. The lactiferous tubes are indistinct before puberty, small in the virgin, and in general in the sterile, and during the intervals of preg¬ nancy, and large only at the close of that period, and du¬ ring the process of suckling. The nipple of the female breast is a flat, conical process, the shape of which is well known, consisting externally of skin, with thin delicate corion and epidermis, internally of mucous membrane, and an intermediate network of dilata¬ ble arteries and veins mutually and freely communicating. These parts are united by filamentous tissue, which varies in quantity at different periods. But from the vessels now mentioned the nipple derives its property of occasional erec¬ tion, especially under the influence of mental emotions. The breast derives its blood from the internal mamma¬ ries, the intercostals, and the thoracics or external mam¬ maries, the branches of which penetrate between the lo¬ bules of the gland. It has lymphatics, though not more abundantly than any other organ. The nerves are chiefly cutaneous. The mammary gland is separated from the pectoral muscle by a thick cushion of adipose substance, on which it rests ; and it derives a gentle conical elevation from the subcutaneous adipose tissue. The mammary skin is re¬ markable for the delicacy and softness of the corion. CHAP. III. THE PRODUCT OF GENERATION. The ovum or impregnated germ, the result of the union of the sexes, consists of an embryo or new animal, inclosed in several membranes, and attached to the inner surface of the uterus by a vascular mass. Of the membranes, one, the decidua (epichorion), be¬ longs to the uterine surface; the other two, the chorion and amnion, belong to the foetus or embryo. The decidua consists of two parts, an external (decidua vera), and an internal (decidua reflexa) ; both modifications of albumi¬ nous secretion. The chorion, the outer covering of the foetus, is a thin transparent membrane, covered with vil- losities on both surfaces, but especially the external. The amnion is a thin transparent membrane, adhering feebly by toniana ; 2>d, the urachus, a ligamentous chord proceed¬ ing to the superior fundus of the bladder; and, kth, the umbilical sheath (vagina umbilicalis). In the early period of uterine life, it also contains part of the intestinal canal, the vesicida umbilicalis either partly or wholly, and the omphalo-mesenteric vessels. Of these parts the umbilical veins and arteries, by their connection with the placenta, are the most important. The others our limits allow us merely to indicate. The placenta is a round or orbicular, thick, cake-shaped The pla- mass, with two surfaces, a filamento-vascular, attached to centa. the inner surface of the womb, and a smooth membranous one, to which the umbilical chord is fixed. It consists of lobular portions (cotyledones), separable from each other, and each of which receives a small artery derived from the uterine trunks, which are much enlarged during pregnancy. The average weight of the placenta is 1 pound 2 ounces. The placenta, according to Dr Hunter (Anatomical Description of the Human Gravid Uterus, edit, by Dr Baillie, Lond. 1794), consists of two portions ; a foetal or umbilical, and a maternal or uterine part. The fcetal part is composed entirely of ramifications of the umbilical arteries and umbilical vein. These, divid¬ ing with extreme minuteness, are distributed to all parts of the placenta. The branches of the umbilical arteries finally terminate in the umbilical vein, and have no other termination: all the branches of the umbilical vein arise from the umbilical arteries, and have no other commencement. The maternal part consists of a whitish-coloured sub¬ stance, which is spread over the outer surface of the pla¬ centa in the form of a membrane, and sends off innumer¬ able irregular processes, which pervade its substance as deep as its inner surface. These are everywhere so blended and entangled with the ramifications of the um¬ bilical system, that it is impossible to discover the nature of their union. They are interwoven in such a manner, however, as to leave innumerable small vacuities or cells between them, which communicate freely with each other through the whole mass. The maternal part is full of large and small arteries and veins, none of which are de¬ rived from the vessels of the fcetal part, but all from the arteries and veins of the uterus. All the arteries are serpentine, and much convoluted; the larger, when in¬ jected, are almost of the size of crow-quills; and, after little or no ramification, they terminate abruptly in the cells already described. This is their only termination. The veins have frequent anastomoses, pass in a very slanting direction, and generally appear flattened; some of them are as large as a goose-quill, but many of them very small; and all arise abruptly from the cells of the placenta. This is their only commencement. The umbilical arteries, which are branches of the hypo-Umbilical gastric, ascend beside the bladder and before the rectum, arteries, approach each other, pass over the fundus of the bladder, and reach the navel with the urachus. There they alter their direction, and are wound round the umbilical vein, which proceeds from the placenta by the same aperture (the navel) by which the arteries escape. These arte¬ ries, which are almost equal in diameter to the hypogas¬ tric or posterior iliac, of which they appear to be the con¬ tinuation, diminish in size after birth, and appear then to be mere branches. Eventually they are obliterated and con¬ verted into solid chords, about 1£ inch from their origin. The umbilical vein, which is larger than both arteries Umbilical taken together, is the common trunk of the veins of the vein. 828 ANATOMY. ties of the foetus. Special placenta, from which it proceeds through the umbilical Anatomy, opening or navel, in the folds of the falciform ligament, to the umbilical fossa of the liver, where it divides into two branches, one large, proceeding to the venaportce and liver, another small, into the vena cava, known by the name of venous duct or canal {ductus venosus). The umbilical vein is distributed chiefly to the left lobe of the liver. Anatomical The structure of the foetus differs in many respects P.eculiyri- from that of the adult; and these differences depend on the stage which the process of developement has attained. As it is impossible to trace the history of this interesting process within the limits of this sketch, we shall merely specify the principal anatomical peculiarities by which the foetus is distinguished from the full-grown subject. A large vascular body, denominated the thymus gland, is found to occupy the anterior mediastinum. The kid¬ neys are covered by triangular filamento-vascular bodies, named renal capsules, larger than the glands themselves, and supplied with large blood-vessels. The liver is very large, especially its left lobe, and occupies not only the right hypochondriac and epigastric, but the left hypo¬ chondriac region. The lungs are compact and of a deep red colour, and sink in water; and the bronchial tubes are collapsed and void of air. In the heart the right and left auricle communicate freely by an oval aperture in the septum. The pulmonary artery, rising from the right ventricle, divides, not into two, as in the adult, but into three branches; one on each side, going to each lung, small, and conveying little blood; and one in the middle, proceeding to the aorta, about 9 lines long, named the arterial canal {ductus vel canalis arteri¬ osus'). The umbilical vein, proceeding to the liver, is distributed by about 15 or 20 branches to the left lobe of that organ. In the horizontal furrow it divides into two branches, one of which goes to the portal vein, the other, apparently the continuation of the trunk, opens into the vena cava, under the name of venous duct {ductus vel canalis venosus), forming with it an angle acute above, and provided with a valve. The kidneys consist of lobules as numerous as their tubular cones, which indeed these lobules are, separate from each other. The urinary bladder is not within the pelvis, but in the abdominal part of that cavity; and it terminates above in a point, to which a liga¬ mentous process {urachus), connecting it to the navel, is attached. In the male, the testicles are contained in the abdomen, often immediately behind the internal aperture. Lastly, till the seventh month the pupillary aperture is closed by a peculiar membrane. In the foregoing account of the anatomy of the human body, many points have been treated in a manner too short and cursory, considering their importance; and in the attempt to restrain it within due limits, the heads of several have been only indicated. For those who wish to study the subject more minutely, besides the works occasionally mentioned, we refer to the following general systems. 1. S. Th. Soemmering De Corporis Humani Fahrica ; Latio donata, ab ipso auctore aucta et emendata. Tom. i. De Ossihus, Trajecti ad Mcenum, 1794. Tom. ii. De Li- gamentis Ossium, 1794. Tom. iii. De Musculis, Tendini- bus, et Bursis Mucosis, 1796. Tom. iv. De Cerebro et Nervis, 1798. Tom. v. De Angiologia, 1800. Tom. vi. De Splanchnologia, 1801. This work, which is excellent so far as it goes, and is particularly distinguished for clear arrangement, and distinctness, precision, and accuracy of description, is incomplete. It wants the anatomical de¬ scription of the eye, the ear, and the generative organs in the two sexes. The first two defects, however, are Special ably supplied by the author in his Abbildungen des Mensch- Anatomy. lichen Auges, fol. Frankfort, 1801; and Abbildungen desK^'/^sJ Menschlichen Hoerorganes, fol. Frank. 1806. 2. Trade d'Anatomic Descriptive; par Xav. Bichat, Medicin du Grand Flospice d’Humanite de Paris, Pro- fesseur d’Anatomie et de Physiologic. Tome i. a Paris, 1801; tome ii. et iii. 1802; tome iv. par M. F. R. Buisson, 1803 ; tome v. par Philib. Jos. Roux, Prof. d’Anatomie, 1803. The death of the author interrupted the publica¬ tion of this work in the middle of the third volume, the first part of which only is by Bichat; while the sequel of that volume is compiled from the materials left at his death. This constitutes the most accurate descriptive system yet extant; and the strongest proof of its supe¬ riority is, that its descriptive portion has been very closely copied in the work of Cloquet. 3.

Trade dAnatomie Descriptive, redige d'apres I'ordre adopte d la Faculte de Medicine de Paris; par Hippol. Cloquet, Docteur en Medicine, &c. This is a very good system of descriptive anatomy. In arrangement, M. Clo¬ quet follows that of Bichat; and in description the first volume, and a great part of the second, are copied al¬ most literally from the first, second, and part of the third of that author. It would have been quite as well had this been avowed; for it deprives Bichat of much of his most unquestionable merit, and gives an unfavourable impression of the candour of M. Cloquet. In the sequel of the second, on the vascular system, and the organs of respiration and digestion, the author has availed himself of the materials of Soemmering. 7. Elements of the Anatomy of the Human Body in its sound state, with occasional remarks on Physiology, Patho¬ logy, and Surgery, by Alexander Monro, M. D. &c. 2 vols. Edinburgh, 1825. On the subject of General Anatomy, and several details on the anatomical divisions and peculiarities of the brain, we here beg to refer in general to a work already men¬ tioned, viz. 8. Elements of General and Pathological Anatomy, adapt¬ ed to the present state of knowledge in that science, by David Craigie, M. D. Edinburgh, 1828. The engravings with which the foregoing article is illus¬ trated have been sufficiently explained by literal or nume¬ ral references, in the course of description. We have on¬ ly to add, that fig. 1 and 2 of Plate XXX., from Soemmer¬ ing, are intended to show the important parts at the lower surface of the brain ; fig. 3, from the same, the relations ot the middle band, vault, and septum; and the other two, from Reil, the internal arrangement of the nucleus. Plate XXXI., from Scarpa, shows the phrenic nerve, and the thoracic part of the pneumogastric and sympathetic, wit the cardiac plexus and nerves. Plate XXXII., from Crui - shank, gives a general view of the arrangement of t ie lymphatics.
